Manage Risk Essay

First of all, the aim of business is increasing of income. They should consider how to maintain existing regular income and to increase new revenue by the expansion. When the business is expanded, they should have enough research and money. The expand looks dangerous. For the safety, they need life guards who are strong swimmers and helpers to control houseboat in high winds. It has many interceptive problems for the expansion like climate and noise. For the success, they need equip tent, beach parasol and soundproof walls. Before making an investment in the expansion, they should consider with the profitability. ASSESSMENT TOOL 2 In Australia, federal and state laws protect you, your business and your customers from unfair trading practices and mishandling of personal information. These laws, together with industry codes of practice, help to ensure that your business operates fairly and competitively and that all consumers are adequately informed and protected. In tort law, a duty of care is a legal obligation imposed on an individual requiring that they adhere to a standard of reasonable care while performing any acts that could foreseeably harm others. It is the first element that must be established to proceed with an action in negligence. The claimant must be able to show a duty of care imposed by law which the defendant has breached. In turn, breaching a duty may subject an individual to liability. The duty of care may be imposed by operation of law between individuals with no current direct relationship (familial or contractual or otherwise), but eventually become related in some manner, as defined by common law (meaning case law). Duty of care may be considered a formalization of the social contract, the implicit responsibilities held by individuals towards others within society. It is not a requirement that a duty of care be defined by law, though it will often develop through the jurisprudence of common law. Assessment tool 3: project Part1 Current risk management These are the three ways to control the risk of any loss: Insurance Loss prevention Contingency planning Nearly every warehouse operator has insurance. You need to recognize the significant differences in liability among logistics service providers, common carriers and wholesale distributors scope The place where raw material and/or finished goods are stored is referred to as warehouse or store. Generally, warehouse is structure or building design keeping in mind raw material and finished goods it is going to store. Therefore, warehouse management should be able to: Receive the purchase goods and entered upon the stock register. Inventory Accounting of raw material, work-in-progress or finished goods. Preservation of the inventory Ability to access goods whenever called upon. Appropriate record keeping through coding as to preserve goods and reduce obsolescence. Proper stocking of goods as ensure smooth handling. Political environment The political environment is a key component of the business environment that dictates greatly on the success of your home business. What happens in the politics of your country as well as that of other countries influences a lot your home business. Usually, the term political environment is used to refer to the nature of the political situation in the country where you are doing business or where you intend to do business. Economic climate A general characterization of the overall mood of the global economy or of a regional economy, which captures the status of the stock market, the perception of the economy by consumers, and the availability of jobs and credit. Business decisions such as hiring, borrowing, lending, and investment in new initiatives are often strongly influenced by the overall economic climate. Social Factors We all live in either a multicultural or self society so this means there are many factors that affect or direct our lifestyle. These factors are called social factors. some important social actors are: 1. Religion 2. Ethnicity 3. Family 4. Physical attributes 5. Economic Status 6. Education 7. Locality( Location) 8. Life Partner and children 9. Political System Legal factors Legal factors relate to new laws or directives governing how businesses behave. This can be in relation to other businesses, customers or the environment. For example, it is essential that all agricultural products are used safely. Syngenta seeks to meet and exceed the requirements of local and international laws for all the countries within which it operates. Policy context Climate change is a complex issue and responding to it requires the planner to navigate the rapidly evolving landscape of information, advice, policy and legislation. By providing context and background, this section of the toolkit will help you make informed decisions about developing and implementing policy in this area. Critical success factor (CSF) is the term for an element that is necessary for an organization or project to achieve its mission. It is a critical factor or activity required for ensuring the success of a company or an organization. The term was initially used in the world of data analysis, and business analysis. For example, a CSF for a successful Information Technology (IT) project is user involvement. Stakeholder 1. Accountable – some stakeholders are accountable for the success of the entire project or a particular phase of the project, generally they are the departmental or divisional managers or; 2. Responsible – some stakeholders are responsible for the deliverables, generally they have been charged by management to provide a definitive outcome from the project; or 3. Consultation – some stakeholders are used as consultants like an Subject Matter Expert (SME); or 4. Informed – some stakeholders need to be kept informed, generally management who needs to know where their investment dollars have ended up or external parties. Stakeholder Internal Stakeholders Board members Former board members Staff members Former staff members Volunteers Former Volunteers Donors External Stakeholders Clients Community partners Members of groups served by our organization who are not accessing our services Leaders of color from nonprofit, public, or private sectors Stakeholders do not need to know everything about the technology or even the application. A high level overview with the understanding of what is being  delivered is sufficient. What stakeholders need to provide is a positive energy charge to lead the organisation through this project. Working with such stakeholders will provide the project with a boost of confidence knowing that the stakeholders are enthusiastic about this project. Given the right stakeholders in any given project, the success rate of the project will be much better than having stakeholders with judgemental bias whereby these stakeholders will reflect inappropriate reasoning compared with best practises as provided by the implementation team. This is a crucial step in applying the risk management process. Like many aspects of risk management, the identification of significant risks is often subjective and reliant on personal experience and judgement. For this reason, several heads will be found to be better than one during this phase of the process. It is therefore important that relevant operational staff be closely involved in identifying and/or confirming significant risks under each source category. PART 2 STRENGTHS The strengths listed below were identified in the business: The managing member of the business is committed, dedicated and passionate about providing warehousing and distribution services. The creditworthiness of the business owner The knowledge and skills demonstrated by the member The business has done a study of the market and identified potential customers for their business WEAKNESSES The identified weaknesses for ExpressX Warehousing and Distribution (Transportation) Services are as follows: The lack of highly specialized warehousing and distribution expertise within the business The lack of funding to source highly specialized technology is a weakness for the business The lack of a comprehensive marketing plan and strategy is another weakness The small workforce capacity may result in the business loosing out on lucrative warehousing and distribution opportunities OPPORTUNITIES There are numerous opportunities for the business in terms of Government assistance. The business is open to assistance from agencies such as Small Enterprise Development Agency, The National Youth Development Agency and many others Broad Based Black Economic Empowerment presents great opportunities for ExpressX Warehousing and Distribution Services There are opportunities for South Africans to export products. This may bring about a market for warehousing services as some goods need to be stored in a reliable warehouse prior to being exported The opportunity presented by SETA could open better avenues for learnership and development in the business Other opportunities include the growth in middle income groups as well as the increase in double income families THREATS There is a threat from well established competitors that have a solid goodwill The threat attributable to changes in the preferences and tastes of consumers The threat from substitute services The threat from new entrants as the barriers of entry are not too cumbersome Risks Description Mitigation of risks Finance risk The financial risk is observed from the fact that the contribution to be made the owner is considerably less as compared to the required outside borrowings that are to be sourced from banks in form of a loan. The business owner will retain at least 60% of the profits into the business. This will be done in the first year of operations so as to mitigate the risk within the short term. Market risk The market features well established competitors and therefore ExpressX Warehousing and Distribution (Transportation) Services will have to compete for market share. The market risk may also surface from the fact that most manufacturers, wholesalers, retailers and other parties likely to utilize warehousing services already have in house warehouses and handle their own distribution. The business will seek assistance from small business support agencies such as the National Youth Development Agency for assistance with a comprehensive marketing plan and strategy. The marketing plan and strategy will help the business compete with greater strength and position it to attain a greater customer satisfaction rate. Human resource risk In terms of human resource, the risk may be a result of the business not being able to recruit the right employees and retain quality employees. High quality employees may prove to be costly to retain. The human resource risk will be mitigated by actively pursuing learnership and development activities. The business will seek assistance from SEDA for skills development. Operational risk The business might have capacity and equipment constraints as some goods for storage require special storage facilities. There may also be a risk of not being as efficient and effective due to lack of advanced logistics software and other technologies. The business will in the initial stages focus on storing merchandise that does not require specials storage facilities and then pursue advanced storage facilities at a later stage. The business will strive to source affordable support technologies. Part 3 What are the hazards? Who might be harmed and how? What are you already doing? What further action is necessary? Slips, trips and falls All staff may suffer sprains or fractures if they trip over debris or slip on spillages. Flooring kept dry and quality maintained. All staff trained to maintain good housekeeping standards and ensure stock does not project into gangways. Cleaner empties bins and removes loose debris daily. Pallets stored safely in designated area. Protective non-slip footwear supplied and worn. Suitable absorber to be made available for liquid spills. Staff to be trained to clean and dry any spillages immediately. Extra bins to be provided for waste material near loading bays. Operation of lift trucks Injuries such as fractures or, at worst, fatalities can be caused as a result of: the vehicle crashing into other vehicles and/or other objects; staff and visitors being hit by lift trucks; objects falling from lift trucks onto staff and visitors; lift trucks toppling over; people falling from the vehicle or parts of the vehicle; and being crushed by the mast All operators trained and competent for use of the lift truck.

Strict requirement that only competent drivers may operate lift trucks to be explained to all staff. Disciplinary action to be taken against anyone involved in breaking this rule. Falling objects From racking and during movement A member of staff or any other person in the warehouse may suffer serious injury if struck by a falling object Racking is designed to be suitable for the loads carried and has not been modified. Staff report any damage to racking immediately. System in place to make sure defective pallets withdrawn from use immediately. Protective footwear used by all entering warehouse. Protective gloves provided to handle pallets. Sign fixed to racking stating maximum loads/configuration. Hazardous substances Vehicle exhaust fumes The fumes may cause staff eye irritation and respiratory irritation. Number of vehicles delivering materials is relatively low and exposure very limited; this prevents build-up of fumes. Drivers not allowed to leave vehicles’ engines running in warehouse. Roller shutter doors and warehouse windows open, where practicable, to assist ventilation. No further action required. Bleach and cleaning fluids Direct skin contact could lead to the cleaner getting skin irritation. The vapour may cause the cleaner to have eye irritation or breathing difficulties Cleaner made aware of safe procedures. Rubber gloves used. First-aid facilities (including eye wash) are readily available. Investigate availability of safer alternatives for cleaner. Recharging of forklift truck batteries – potential explosion by release of hydrogen, spillage of acid Burns or fractures from material ejected could affect any worker nearby at the time Batteries charged in designated bay that is well ventilated. Safe system of work used which includes provision and use of goggles and gloves. Potential sources of ignition controlled. Supervisor to monitor and ensure protective equipment is being worn. Falls from height Staff could suffer severe or even fatal injuries if they fell whilst climbing racking All staff are given strict instructions never to climb racking – monitored by supervisors Part 4 Suitable absorber to be made available for liquid spills. Staff to be trained to clean and dry any spillages immediately. Extra bins to be provided for waste material near loading bays. Supervisor to ensure truck drivers check trucks each day before starting. Separate pedestrian entrance(s) with protective barrier rail to be provided next to roller-shutter doors. Housekeeping standards and floor condition to be covered by a monthly inspection by manager and brief record kept. Strict requirement that only competent drivers may operate lift trucks to be explained to all staff. Disciplinary action to be taken against anyone involved in breaking this rule. Sign fixed to racking stating maximum loads/configuration To identify the hazards The manager then wrote down who could be harmed by the hazards and how. For each hazard identified, the manager recorded what controls, if any, were in place to manage these. She then compared these controls to the good practice guidance laid out in Warehousing and storage: A guide to health and safety and Essentials of health and safety at work publications. Where existing controls did not meet good practice, the manager wrote down what further actions were needed to manage the risk. Putting the findings of the risk assessment into practice, the warehouse manager decided who was responsible for implementing the further actions and when it should be done. She wrote this down and when each action was completed it was ticked off and the date recorded. The warehouse manager discussed the findings with the safety representative. They decided to review and update the assessment at least annually, or at any time when major changes to the workplace occurred. The warehouse manager gave out copies of the risk assessment to all members of staff.

An Outline of the Cell Theory

Chapter 2 IB Biology 2. 1 Cell Theory 2. 1. 1 Outline the cell theory (2). †¢All organisms are composed of one or more cells †¢Cells are the smallest units of life †¢All cells come from preexisting cells †¢TOK: cell theory replaces the former ideas of spontaneous generation or abiogenesis in which inanimate matter assembles itself into living forms †¢Exception: muscle cells- more than 1 nucleus, very long; (fungal cells) hyphae roots- not a single unit; protoctista- not specialized to single function; subcellular things like organelles 2. 1. Discuss the evidence for the cell theory (3). †¢Robert Hooke first described cells in 1665 while observing cork with a microscope he built. Coined the term â€Å"cell†Antoine van Leeuwenhoek observed the 1st living cells and referred to them as animalcules. â€Å"microscope† †¢In 1838, botanist Mathias Schleiden stated that plants are made of independent separate being called cells. Later, Theoder Schwann made a similar statement about animals. †¢The 2nd principle continues to gain support because we have not been able to find any living entity that is not made of at least one cell. Louis Pasteur in the 1860s performed experiments to support the last principle. After sterilizing chicken broth by boiling, Pasteur showed that living organisms would not ‘spontaneously’ reappear. â€Å"biogenesis† †¢Only after exposure to preexisting cells was life able to re-establish itself in the chicken broth. †¢Eukaryotes- mitosis; prokaryotes- binary fission; thus all cells have a common ancestor- original ancestral form 2. 1. 3State that unicellular organisms carry out all the functions of life (1). †¢Functions include: Metabolism- chemical reactions that occur within an organism †¢Growth- may be limited but is always evident in some way †¢Reproduction- hereditary molecules that can be passed to offspring †¢Response- to environment is imperative to survival †¢Homeostasis- maintain a constant internal environment ex: temp †¢Nutrition- provide a source of compounds with many chemical bonds which can be broken to provide the organism with the NRG and the nutrients necessary to maintain life CHNOPS 2. 1. 4 Compare the relative sizes of molecules, cell membrane thickness, viruses, bacteria, organelles and cells, using the appropriate SI unit (3). Cells- 100 micrometers (plant) †¢Organelles- < 10 micrometers †¢Bacteria- 1 micrometer †¢Viruses- 100 nanometers†¢Membranes- 10 nanometers thick †¢Molecules- 1 nanometer †¢Animal cell- 10 micrometers †¢cm = 10-2 m †¢mm = 10-3 m †¢um = 10-6 m †¢nm = 10-9 m †¢A = 10-10 m 2. 1. 5 Calculate the linear magnification of drawings and the actual size of specimens in images of known magnification (2). †¢Magnification = size of image divided by the size of specimen †¢Magnification = measured length / scale ba r level †¢Actual size = measured length / magnification 2. 1. Explain the importance of the surface area to volume ratio as a factor limiting cell size (3). †¢In the cell, the rate of heat and waste production and rate of resource consumption are functions that depend of its volume. †¢Most of the chemical reactions occur in the interior of the cell and its size affects the rate of these reactions.†¢The surface of the cell, the membrane, controls what materials move in and out of the cell. †¢Cells with more surface are per unit volume are able to move materials in and out of the cell, for each unit volume of the cell. As the width of the object increases, the surface area also increases but at a much slower rate than the volume. †¢This means that a large cell has less surface area to bring in needed materials and to rid the cell of waste than a small cell. †¢Because of this, cells are limited to the size they can attain and still be able to carry ou t the functions of life. Large animals have more cells not larger ones. †¢A large surface area to volume ratio means the cell can act more efficiently: for every unit of volume that requires nutrients or produces waste, there is more membrane to serve it. But this is not always an advantage- cell can lose heat quickly.†¢As organisms grow, cells divide. 2 small cells are more efficient than one. †¢Alveoli in lungs maximize surface for gas exchange. 2. 1. 7 State that multicellular organisms show emergent properties (1). †¢Different things come together to make process †¢Cells-tissues-organs-etc. †¢Ability to reproduce themselves. Allows possibility of growth and for replacement of damaged or dead cells. 2. 1. 8 Explain that cells in multicellular organisms differentiate to carry out specialized functions by expressing some of their genes but not others (3). Start out as single cell that reproduces at a rapid rate then the resulting cells go through a dif ferentiation (different cells- different functions- to run an organism) process to produce all required cell types that are necessary for organism. †¢Every cell in a multicellular organism contains all the genes of that organism. However, the genes that are activated vary from cell to cell. †¢Differentiation- when we break something complex into its component pieces, they each appear to be simple. Combined, they can perform a whole new function.Cells within a multi cellular organism specialize their function. †¢Examples: muscles cells, cardiac cells †¢This differentiation process is the result of the expression of certain specific genes but not others †¢Genes allow for the production of all different cells in the organism †¢Each cell contains all the genetic info for the production of the complete organism †¢Each cell becomes a specific type of cell dependent of which DNA segment becomes active 2. 1. 9 State that stem cells retain the capacity to d ivide and have the ability to differentiate along different pathways (1). Retain ability to divide and differentiate into various cell types †¢Embryonic stem cells retain the ability to form any type of cell in an organism and can even form a complete organism †¢When stem cells divide to form a specific type of tissue, they also produce some cells that remain as stem cells. This allows for the continual production of a particular type of tissue.†¢Pluripotent- give rise to any type of cell †¢Treating diseases? 2. 1. 10 Outline one therapeutic use of stem cells (2). †¢Replace differentiated cells lost due to injury Therapeutic cloning- implanted stem cells replace lost cells †¢Tissue- specific stem cells- these cells reside in certain tissue types and can only produce new cells of that particular tissue †¢For example, stem cells have been introduced to humans to replace the damaged bone marrow of some leukemia patients †¢Bone marrow transplants are one of the many therapeutic uses of stem cells. Stem cells found in the bone marrow give rise to the red blood cells, white blood cells and platelets in the body. These stem cells can be used in bone marrow transplants to treat people who have certain types of cancer.When a patient has cancer and is given high doses of chemotherapy, the chemotherapy kills the cancer cells but also the normal cells in the bone marrow. This means that the patient cannot produce blood cells. So before the patient is treated with chemotherapy, he or she can undergo a bone marrow harvest in which stem cells are removed from the bone marrow by using a needle which is inserted into the pelvis (hip bone). Alternatively, if stem cells cannot be used from the patient then they can be harvested from a matching donor.After the chemotherapy treatment the patient will have a bone marrow transplant in which the stem cells are transplanted back into the patient through a drip, usually via a vein in the chest or the arm. These transplanted stem cells will then find their way back to the bone marrow and start to produce healthy blood cells in the patient. Therefore the therapeutic use of stem cells in bone marrow transplants is very important as it allows some patients with cancer to undergo high chemotherapy treatment.Without this therapeutic use of stem cells, patients would only be able to take low doses of chemotherapy which could lower their chances of curing the disease. †¢Ethical issues- embryonic stem cells come from embryos obtained from labs doing IVF. involves death of embryo. 2. 2 Prokaryotic Cells 2. 2. 1 Draw and label a diagram of the ultrastructure of Escherichia coli (E. coli) as an example of a prokaryote (1). †¢Plasmid is circular thing not on diagram. Refer to book. †¢Size of cell: 1-2 um †¢Absence of membrane bound organelles Prokaryote examples: (look at notes for pictures) †¢straight rod- Escherichia †¢Club shaped rod- corynebacterium â⠂¬ ¢Spore forming rods- bacillus †¢Coccus Staphylococcus 2. 2. 2 Annotate the diagram with the functions of each named structure. †¢Cell wall: Protects the cell from the outside environment and maintains the shape of the cell. It also prevents the cell from bursting if internal pressure rises. †¢Plasma membrane: Semi-permeable membrane that controls the substances moving into and out of the cell. It contains integral and peripheral proteins.Substances pass through by either active or passive transport. †¢Cytoplasm: Contains many enzymes used to catalyze chemical reactions of metabolism and it also contains the DNA in a region called the nucleoid. Ribosomes are also found in the cytoplasm. †¢Pili: Help bacteria adhere to each other for the exchange of genetic material. Involved in transfer of DNA in a process called conjugation (direct contact between bacterial cells in which plasma DNA is transferred between a donor and a recipient cell) †¢Flagella (s ingular flagellum): Made of a protein called flagellin.Helps bacteria move around (mobility) †¢Ribosomes: They are the site of protein synthesis. Contributes to protein synthesis by translating messenger RNA. free in cytoplasm (70s) †¢Nucleoid: Region containing DNA; involved with cell control and reproduction †¢Plasmid- small, circular DNA not connected to main chromosome; replicate independently of chromosomal DNA; not required by cell under normal conditions but it may help the cell adapt to unusual circumstances; normal to find at least one anti-biotic resistance gene within a plasmid †¢Slime capsule- sticky layer outside of cell wall, sticks cells together . 2. 3 Identify structures from 2. 2. 1 in electron micrographs of liver cells (2). 2. 2. 4 State that prokaryotic cells divide by binary fission (1). †¢Binary fission- simple division process in which DNA is copied and 2 daughter chromosomes become attached to different regions on plasma membrane and cell divides into 2 genetically identical daughter cells. Process elongation of cell 2. 3 Eukaryotic Cells 2. 3.1 Draw and label a diagram of the ultrastructure of a liver cell as an example of an animal cell (1). . 3. 2 Annotate the diagram with the functions of each named structure. †¢Ribosomes: Found either floating free in the cytoplasm or attached to the surface of the rough endoplasmic reticulum and in mitochondria and chloroplast. Ribosomes are the site of protein synthesis as they translate messenger RNA to produce proteins. †¢Rough endoplasmic reticulum: Can modify proteins to alter their function and/or destination. Synthesizes proteins to be excreted from the cell. Lysosome: catalyze the breakdown of proteins, nucleic acids, lipids and carbs, fuse with old or damaged organelles so recycling can occur, breakdown of materials that are brought in by phagocytosis †¢Golgi apparatus: Receives proteins from the rough endoplasmic reticulum and may further modify t hem. It also packages proteins before the protein is sent to it’s final destination which may be intracellular or extracellular. †¢Mitochondrion: Is responsible for aerobic respiration. Converts chemical energy into ATP using oxygen. †¢Nucleus: Contains the chromosomes and therefore the hereditary material.It is responsible for controlling the cell. Extra: †¢Smooth ER- production of membrane phospholipids can cellular lipids, production of sex hormones, detoxification of drugs in liver, storage of calcium ions needed for muscle contractions, transportation of lipid based compound, to aid in liver in releasing glucose into bloodstream when needed †¢Centrosome- a pair of centrioles at right angles; involved in assembling microtubules which are important in providing structure and allowing movement and cell division †¢Vacuole- storage organelle; store potential food to provide nutrition, metabolic wastes and toxins to be expelled, and ater; enables cells to have a higher surface area to volume ratios even at larger sizes; in plants, uptake of h2o provides rigidity 2. 3. 3 Identify structures from 2. 3. 1 in electron micrographs of liver cells (2). 2. 3. 4 Compare prokaryotic and eukaryotic cells (3). Prokaryote Eukaryote DNA in a ring form without proteinDNA with proteins as chromosomes/chromatin DNA free in the cytoplasm- no nucleusDNA enclosed within a nuclear envelope No mitochondriamitochondria 70S ribosomes80S ribosomesNo internal compartmentalization to form organellesinternal compartmentalization present to form many types of organelles Size less than 10 micrometersSize more than 10 micrometers †¢also: unicellular vs. multicellular †¢no membrane bound organelles vs. membrane bound organelles †¢binary fission vs. mitosis †¢asexual reproduction vs. asexual and sexual reproduction †¢similarities: both cells have some sort of outside boundary that always involves a plasma membrane, both carry out all fun ctions of life, DNA is present in both . 3. 5 State 3 differences between plant and animal cells (1). Plant Animal Outer cell wall with a plasma membrane just insideOnly a plasma membrane Chloroplasts No chloroplasts Large centrally located vacuolesNo vacuoles/ or small ones Store carbs as starchStore carbs as glycogen Do not contain centrioles within a centrosome areaContain centrioles within a centrosome area Fixed, often angular, shape because of a rigid cell wallCell is flexible and more likely to be a rounded shape . 3. 6 Outline 2 roles of extracellular components (3).†¢The plant cell wall gives the cell a lot of strength and prevents it from bursting under high pressure as it is made up of cellulose arranged in groups called microfibrils. It gives the cell its shape, prevents excessive water up take by osmosis and is the reason why the whole plant can hold itself up against gravity. Prevents entry of pathogens. Allows turgor pressure/ high pressure to develop inside the cell. The animal cell contains glycoproteins in their extracellular matrix (ECM) which are involved in the support, movement and adhesion of the cell. Cell to cell interaction, strengthens plasma membrane, allows attachment between adjacent cells, directs stem cells to differentiate 2. 4. 1 Draw and label a diagram to show the structure of membranes (1). 2. 4. 2 Explain how the hydrophilic and hydrophobic properties of phospholipids help to maintain the structure of cell membranes (3). One area of membrane is water soluble and polar and is hydrophilic †¢The other area isn’t water soluble and is non polar- hydrophobic†¢These hydrophobic and hydrophilic regions cause phospholipids to always align as a bilayer if there is water present and there is a large number of phospholipid molecules †¢Membrane is flexible since fatty acid tail do not strongly attract one another †¢What maintains the overall structure of membrane is the tendency water has to form hydroge n bonds †¢In hydrophobic region (fatty acid tails) in animal cells these are cholesterol molecules- determine membrane fluidity (changes temp) †¢Proteins are embedded in fluid matrix of phospholipid bilayer (mosaic effect) †¢Integral proteins have both hydrophobic and hydrophilic regions in the same protein †¢Hydrophobic region (mid section of phospholipid membrane) holds protein in place †¢Hydrophilic region is exposed to water solutions on either side of membrane †¢Peripheral proteins do not protrude into the middle hydrophobic region but remain bound to the surface of the membrane 2.4. 3 List the functions of membrane proteins (1). †¢Hormone binding sites- have specific shapes that fit shape of specific hormone †¢Enzymatic action- catalyze chemical reactions †¢Cell adhesion- proteins hook together to form connections †¢Cell to cell communication- provide identification †¢Channels for passive transport- high to low concentrati on †¢Pumps for active transport- proteins shuttle a substance from one side of membrane to another by changing shape; ATP 2. 4. 4 Define osmosis and diffusion (1). †¢Diffusion is the passive movement of particles from a region of high concentration to a region of low concentration.Osmosis is the passive movement of water molecules, across a partially permeable membrane, from a region of lower solute concentration to a region of higher solute concentration (hypo-osmotic solution to hyperosmotic solution). †¢Facilitated diffusion- involves a membrane with specific carrier proteins that are capable of combining with the substance to and its movement 2. 4. 5 Explain passive transport across membranes by simple diffusion and facilitated diffusion (3). †¢Simple diffusion- substances other than water move between phospholipids molecules or through proteins which possess channels †¢Facilitated diffusion- nonchannel protein carriers change shape to allow movement of substances other than water. No NRG.Polar molecules need help. †¢Substances that move passively across membrane are influenced by size and shape †¢Small substances and nonpolar move with ease; large, polar, or both do not †¢Channel proteins- create a hydrophilic pore in membrane through which small changed particles (ions) can diffuse into cell †¢Transport proteins- help move substances (glucose) into cell. Substrate binds to protein which carries molecules across membrane and releases it inside cell 2. 4. 6 Explain the role of protein pumps and ATP in active transport across membranes (3). †¢Active transport involves the movement of substances through the membrane using NRG from ATP.The advantage of active transport is that substances can be moved against the gradient, meaning from low to high concentration †¢This is possible because the cell membrane has protein pumps embedded it which are used in active transport to move substances using ATP †¢E ach protein pump only transports certain substances so the cell can control what comes in and goes out †¢Transport or carrier proteins †¢Ex: Na +/ K + pump. Sodium moved out of cell, potassium moved in (important for nerve cells) 2. 4. 7 Explain how vesicles are used to transport materials within a cell between the rough ER, Golgi apparatus, and plasma membrane (3). †¢Materials are transmitted between rough ER, Golgi app, and plasma membrane †¢Nucleus contains chromosomes that contain genes for coding proteins.RNA passes from nucleus to cytoplasm †¢Rough ER contains ribosomes which make proteins intended for export †¢Protein goes into lumen of Golgi app for processing before it leaves through the cell surface membrane by exocytosis 2. 4. 8 Describe how the fluidity of the membrane allows it to change shape, break and reform during endocytosis and exocytosis (2). †¢The phospholipids in the cell membrane are not solid but are in a fluid state allowin g the membrane to change its shape and also vesicles to fuse with it. †¢This means substances can enter the cell via endocytosis and exit the cell via exocytosis. The membrane then returns to its original state. †¢In exocytosis the vesicles fuse with the membrane expelling their content outside the cell.The membrane then goes back to its original state. Endocytosis is a similar process which involves the pulling of the plasma membrane inward so that a vesicle is pinched off it and then this vesicle can carry its content anywhere in the cell. †¢Cell takes up substance by surrounding it with membrane, ATP †¢2 types: †¢pinocytosis (substance is liquid) †¢phagocytosis (substance is solid) †¢endocytosis and exocytosis- active transport that requires ATP; common in unicellular organisms Summary of processes: ATP requiredConcentration gradient DiffusionNoDown (high to low) Facilitated diffusionNoDown OsmosisNoDown Active transport with carrier proteinsYes Against is possible EndocytosisYesAgainst is possible 2. 5 Cell Division 2. 5. Outline the stages in the cell cycle, including interphase (G1, S, G2), mitosis, and cytokinesis (2). †¢The first stage of cell division is interphase which is divided into 3 phases; G1, S and G2. The cell cycle starts with G1 (Gap phase 1) during which the cell grows larger. This is followed by phase S (synthesis) during which the DNA is replicated. Finally, G2 (gap phase 2) is the second growth phase in which organelles increase in number, cell grows and preps for mitosis, DNA begins to condense form chromatin to chromosomes and microtubules begin to form. †¢? The fourth stage is mitosis, which is divided into prophase, metaphase, anaphase and telophase.During mitosis the spindle fibers attach to the chromosomes and pull sister chromatids apart, providing the same genetic material to each of these locations. This stage separates the two daughter genomes. †¢Finally, cytokinesis is the last stage during which the cytoplasm divides to create two daughter cells. In animal cells the cell is pinched in two to form a cleavage furrow while plant cells form a plate between the dividing cells. 2. 5. 2 State that tumors (cancer) are the result of uncontrolled cell division and that these can occur in any organ or tissue (1). †¢Proto-oncogenes are genes that produce proteins, which stimulate growth (cell division). If mutation occurs, a tumor will form.

An Unconventional Love- Sonnet 130 Essay

If one were talking about a beloved, one would go out of one’s way to praise her and point out all of the ways that she is the best. However, in William Shakespeare’sSonnet 130, Shakespeare spends the poem comparing his mistress’s appearance to other things, and tells the reader how she doesn’t measure up to the comparisons. While using the standard Shakespearean iambic pentameter with a rhyme scheme of AB-AB/CD-CD/EF-EF/GG, he goes through a laundry list, giving us details about the flaws of her body, her smell, and even the sound of her voice. Yet at the end of the poem, he changes his tune and tells the reader about his real and complete love for her. Shakespeare’s Sonnet 130 takes a turn from the clichà © love poems of his time by mocking the common comparisons and telling the truth about his lover’s appearance. The first quatrain briefly describes the woman’s physical appearance by using comparisons to nature. To begin the poem, Shakespeare uses a simile by saying, â€Å"My mistress’ eyes are nothing like the sun† (1). One may mistake this line as a criticism, but he is merely saying that her eyes are nothing like the sun because they are better than it. The speaker also says, â€Å"If snow be white, why then her breasts are dun† (3). By avoiding a direct simile, Shakespeare gives the reader a strong mental image of sparkling white snow and lays it next to the equally vivid image of dun (grayish-brown) breasts. â€Å"Dun† is often used to describe the color of an animal and is not the kind of thing a woman would like her breasts to be compared to. Throughout the second quatrain, the speaker continues to criticize his mistress’ appearance and breath. Shakespeare says, â€Å"I have  seen roses damasked red and white,/ but no such roses see I in her cheeks† (5-6). White, red, and damasked were the only three colors during the poem’s time period. The speaker says he has seen roses separated by color (â€Å"damasked†) into red and white, but he sees no such roses in his mistress’ cheeks. The use of the word â€Å"damasked'† encourages Shakespeare’s criticism that his mistress is not like the rest of the women. The speaker also says, â€Å"And in some perfumes i s there more delight/ than in the breath that from my mistress reeks† (7-8). The word â€Å"reeks† promotes a strong image of just how far from perfect this woman is and forces the reader to take a look at the definitions of female beauty. The word was not as suggestive of unpleasant exhalations as it is nowadays, but it tended to be associated with steamy, sweaty and unsavory smells. The expression is relative with the earlier description of dun breasts. The third quatrain is a shift from the previous quatrains that describe what the mistress is not by describing her voice and contrasting her to a goddess. Shakespeare says, â€Å"I love to hear her speak, yet well I know/ that music hath a far more pleasing sound† (9-10). In these lines, the speaker draws on a more cultural image, comparing music to his mistress’ voice. He is saying that he literally loves to hear her voice, even though he knows that music is much more pleasant to hear. Alliteration is used in line 11 to emphasis the woman’s gait when the speaker says, â€Å"I gr ant I never saw a goddess go† (line 11). He also says, â€Å"My mistress, when she walks, treads on the ground† (line 12). In ancient times, a mortal was able to recognize a goddess by her particular manner of walking. The speaker could be talking about her graceless gait but could also be commenting on the fact that she is not a goddess and walks the earth like any other woman would. William Shakespeare’sSonnet 130 takes a turn from the clichà © love poems of his time by mocking the common comparisons and telling the truth about his lover’s appearance. In the couplet, the speaker shows his full intent, which is to insist that love does not need conceits in order to be real, and women do not need to look like flowers or the sun in order to be beautiful. The exaggerated comparisons make this sonnet enjoyable because the reader is constantly wondering if the speaker hates his mistress or is simply being witty. I chose this poem because I appreciate Shakespeare’s approach in writing this love poem, and I continuously enjoy the poem no matter how many times I re-read it. The satiric tone and use of metaphors  were the most successful elements of the poem, with no unsuccessful elements, in my opinion. Sonnet 130 plays an elaborate joke on the conventions of love poetry common to Shakespeare’s day, and is so well perceived that the joke remains humorous today.

Critical response Assignment Example | Topics and Well Written Essays - 500 words

Critical response - Assignment Example Each of these decisions has both inherent good and harm in it. Therefore, the second step is for Sam to evaluate what good or harm will be obtained from each action and who will be affected. If he keeps silent, then the wellbeing of a large number of people will be placed at risk and the company will keep on expanding and earning massive profits. If he breaks the confidentiality agreement and exposes the company then the public will be informed and harm will be prevented, but the company will suffer serious losses, he will lose his job and throw his family into financial instability once more. Hence, Sam, being a utilitarian and believing that the ‘end justifies the means’ will choose to keep silent, saving the company, as well as himself and his family. For Sam, the greatest good is the one that will benefit his family and, indirectly, the company. He will not sacrifice his job and his family for things that are out of his control, such as the people choosing to buy cigarettes from Greyarea. They have their own choice, and Sam has his own. If Sam is a Deontologist, then he will definitely break the confidentiality agreement and expose the unethical actions of Greyarea, regardless of the consequences to him, to his family, to the company, and to other stakeholders. Deontology is duty-based ethics and it claims that individuals are morally obliged to make decisions or act based on a specific set of rules and ideals irrespective of outcome (Alavudeen et al. 40). Thus, Sam, being a deontologist, knows that what the company is doing is immoral, for it deceives and cheats the public. And so, based on such knowledge alone, of such discovery that the company is unethical, Sam will carry out his moral duty, and that is to inform the public about the company’s unethical behavior. Sam will do something about the situation out of respect for the moral or ethical codes and out of

Design an Alternative Interface Essay Example | Topics and Well Written Essays - 2500 words

Design an Alternative Interface - Essay Example First of all, the interface should ensure that all key characteristics are among the inclusions in the design. These are the ten principles of interface design. This is in reference to discussions in â€Å"Hierarchical Task Analysis,† by Shepherd. There are ten key principles for the design of a user interface. Heuristics refers to these principles because of their nature in reference to usability guidelines. Below is a list of these general principles (Buxton, 2007). 6. Recognition rather than recalling – the designer does not require the user to remember information in different sections of the dialogue. The instructions should also be visible enough for easy comprehension. 8. Minimalist and aesthetic design – dialogues should avoid unnecessary information. All units of information compete for relevant units of information in dialogues, as the relative visibility diminishes. The following is an illustration of the appearance of the design. It includes implementation of the information above. It should provide the user with different applications which enables them access sufficient information. One of the characteristics of the new interface is it enhances sharing of data; the book by the name â€Å"Hierarchical Task Analysis† has further illustrations. This capability should have no limits as it will ensure the promotion all over the world. User will feel changes as the limitation of the current interface are solved in the new interface. This capability will be impacted by an account so that; senders can always drop the data for the receivers to download at their own disposal (Shneiderman, 1998). The interface should have the capabilities of analyzing weather changes. This is because areas like California suffer highly depending on daily activities, which rely on weather; this is in reference to, Human Computer Interaction. The interface should perform this task by automatically, detecting location through time zones (Buxton, 2007). The

Literature review saudi arabian culture Example | Topics and Well Written Essays - 2750 words

Saudi arabian culture - Literature review Example that the Western understanding of Muslim women appears unduly influenced and limited by evidence from only a few regions of Saudi Arabia2. The social science scholarship most familiar to the West about Muslim women seems to focus disproportionately on the Middle East and North Africa region (MENA). Often seen as the land of Muslim excellence, ‘MENA’ is in fact home to fewer than 20 percent of the world’s Muslims. Nevertheless, it is an unfortunate reality that women in Saudi Arabian society, and in its local communities, face gender-based inequalities associated with Saudi’s so-called ‘patriarchal gender system.3’ Aspects of this originally pre-capitalist system persist in rural areas across a wide swath of lands, both Muslim and non-Muslim, from East Asia to North Africa. The Saudi Arabian social system, regardless of its religion, features and encourages kin-based extended families, male domination, early marriage (and consequent high fertili ty), restrictive codes of female conduct, the linkage of family honour with female virtue, and occasionally, polygamous family structure. In all Muslim areas, veiling and sex-segregation generally form part of the gender system.4 The seclusion of women from the rest of the world alongside the concurrent ban on sexualisation of women in the public eye has led to increased levels of sexual violence and abuse directed towards both women and children5. It is only recently that researchers have uncovered more accurate statistics on the occurrence of this abhorrent violence following the establishment of human rights based projects and refuges to rescue and protect women and children as well as to promote the welfare of the wider-public in general. 1) General Theoretical Background: Women and Gender An important foundation for the study of women and gender is to be found in the feminist literature of the 1970s. Around this time scientists had begun to untangle the complex interplay betwee n biological gender differences, and the abstract concept of gender, which is now a socially determined construct imposed on all human beings from the moment they are born. (Maccoby and Jacklin, 1974) Terminology such as ‘the sexual revolution’ (Millet, 1970) were used to describe the birth of consciousness about women’s subordination to men in patriarchal societies and many aspects of women’s lives were re-examined in this light. This analysis is similar to some Marxist ideas because it identifies the concentration of wealth and power in one area as the source of oppression: â€Å"the position of women in patriarchy is a continuous function of their economic dependence.† (Millet: 1970) Another American feminist studied the ways in which women in patriarchal societies are conditioned to adopt domestic and subservient roles, stressing the social constraints, which are described as â€Å"a comfortable concentration camp.† (Friedan: 1963, p. 438 ) Later, scholars moved away from

International law extra Essay Example | Topics and Well Written Essays - 500 words

International law extra - Essay Example It was however difficult to pinpoint the location of the 48th Battalion responsible for the Tet offensive. After gathering intelligence reports, the military authorities collectively decided that the 48th Battalion was near the village of My Lai. American military authorities then planned to seek out and neutralize the 48th Battalion through the elements of the Task Force Barker. Their orders from their military officers were to clean out the area and destroy the villages. The civilians however were to be spared. When the different platoons, including Charlie Company, were deployed to the suspected area, they met no resistance, no Viet Cong, no 48th Battalion. Only Vietnamese civilians appeared to occupy the village. And for William Calley and other members of the Charlie Company, they felt it was their time to take revenge for the men they lost in combat and for the atrocities that the Viet Cong committed against them. â€Å"Soldiers shot old men sitting outside their homes, women carrying water, children searching for places to hide† (Olson & Roberts, p. 22). Not one of these Vietnamese fired back, and yet they were gunned down by the soldiers. Calley ordered his men to shoot all the civilians because their superior officers ordered them to. Some of the soldiers disobeyed the orders and others reluctantly carried out the orders. Calley was in his element. He happily pulled the trigger on every man, woman and child at the My Lai village. And in the end, Charlie Company â€Å"rounded up and killed as many as 500 unarmed women, children, and elderly Vietnamese in the hamlet of My Lai 4 in Son My, South Vietnam† (Wilkins, p. 77). Lt. Calley was court-martialed, charged with the murder of Vietnamese civilians. Four officers and nine enlisted men were also charged with murder. However, most of these charges were dropped and only a few, especially the charges against Calley, made it through to trial. Private

Play And Childrens Development Research Paper Example | Topics and Well Written Essays - 1500 words

Play And Childrens Development - Research Paper Example In a study that measured the rate of video game playing by students compared to their academic performance, video gaming or passive gaming was found to have negative effects on the cognitive ability of students. The study reported decreasing interest in academic work due to its strong addictive nature that ties the students’ mind to such video gaming. According to this study, teachers and policy makers in education have constantly voiced their concerns regarding the detrimental effects of video passive gaming and TV watching. The study found that video gaming was negatively correlated to academic performance among college students, with the variation being much higher in male students compared to females. This may be explained by the time displacement hypothesis where media consumption takes away most of time that would be used in the intellectually challenging academic activities. Shelving such intellectual challenging activities thus leads to lower cognitive development amon g such constant passive game players, resulting to lowered cognitive development. Thus as Kantor (259) asserts, physical or active play would lead to improvement in cognitive development due to the mental activities and body systems involved, all which work to improve healthy development of an individual. Russel and Newton (295) relate passive gaming to the acute increase in obesity cases among teenagers today. According to this study, child obesity increases due to lack of enough time for physical activities, and increase in passive gaming and watching screen content.TV watching and passive gaming are rapidly displacing children physical activities with more teenagers showing increased preference to passive gaming over physical activities. The... The self-efficacy of children becomes critical in social development. Increasing children efficacy can be enhanced through increased self-confidence, which is attained when children learn to do things alone. Independence can be developed by ensuring children plan their own games and are supported and not guided in such unstructured games, which improve a child’s efficacy. Structured games will, therefore, reduce the learning process in a child compared to unstructured games, which reduces their self-efficacy, and limits their social development. Some of the plays that children can use freely to express themselves and enhance development are drawing, collages, using paper mache and block games where children arrange blocks to form different patterns. Playing is not only beneficial in developing physical health and abilities but has a great impact on social and psychological attributes in children. To ensure the benefits of physical play among children for both psychological and physical health, child play should not be directed. Allowing children to design their games and construct meanings from such games leads to creativity and self-drive, which is critical in ensuring cognitive development in children. Therefore, active play in children has to be encouraged and facilitated in any way possible to avoid health complications in obesity and other negative behaviors related to passive gaming. Such an approach in a child’s play promotes major psychological, social and physical benefits involved in physical gaming.

Cracking the Code of Change Essay Example | Topics and Well Written Essays - 1500 words

Cracking the Code of Change - Essay Example In most of the cases we see that change management is considered necessary and good (Ogbonna, and Wilkinson, 2003, p. 1151). The contemporary ideas for change reflect that the managers must be capable enough to plan out organizational changes and also be responsive enough to the changing environment. Organizational changes require large efforts and time of the managers as well as other employees. According to a British Survey, about 94 percent of the organizations experienced planned change in 1997 (Study, and Grey, 2003, p. 2). This study aims at discussing the change management theories and every other dimensions of change in the organizations. It would begin with a basic overview on change and the traditional approaches on change management in organization. Then the essay would lead the readers to the different theories presented by different authors on change and its strategic impact on the organization. The essay would also include the impact of change on the competitive advanta ge of the company by citing examples from the article â€Å"Cracking the Code of Change". ... Other authors have different perspectives. They believe that organizational change includes behavioral patterns of blocking higher performances of the organization and analyzing the consequences to understand the underlying values and assumptions. The secondary reason could be the culture, which should also be considered. There are numerous approaches to change or change management and many ways to categorize them. The two major ones are the Planned and Emergent approach. Since 1950s to 1980, the theories of organizational change were dominated by the planned approach. This was developed by Kurt Lewin and further revised by the Organization Development movement (Simms, 2005, p. 121). The planned approach focused on improving the effectiveness and the operation of the human resource of the organization. This could be done with the help of team based programmes for change management (Collins, 1998, p. 60-62). However, in 1980s the world received the oil shocks and this led to the sever e economic downturn in the western countries. In this scenario, it was absolutely clear that organization had to transform them to face the situations. In this situation the Planned changed started receiving criticism and questions were raised with regards to its effectiveness and efficacy. Against the backdrop of the economic downturns in the west, the Emergent approach began taking the position of the traditional change approach. This approach was based on the new economic situation of the market and organization found the touch of reality in this approach. The emergent approach viewed change as a process where individuals are the parts of the organization who deal separately with individual goals, one at

Promoting diversity within a health and social setting Essay Example for Free

Promoting diversity within a health and social setting Essay In this report I am going to outline The Mental Health Act alongside this, the procedures and codes of practise and how both of these aim to promote diversity and assessing the effectiveness of these measures in place. The Mental Health Act aims to safeguard the vulnerable, by ensuring they are treated fairly and equally by services and given permission to health care, for example hospital treatment if required. The term mental illness or a personality disorder is used to describe someone with a mental disorder. The key principles of the act include keeping the service users best interest at heart and if unwise decisions are made by the user, the least restrictive option should be made. The mental health acts helps to promote diversity, because it ensures that the individual themselves will not be taken advantage of and their choices are met with full understanding before a decision has been made. This also makes sure that the person who holds the right to overrule the decision making follows under the act closely. The codes of practise aim to provide rules and regulations on how professionals should behave in a health and social care service. Most importantly, they provide specific standards of practise for each situation. For example, there is a code of practise for nursing and midwifery, known as ‘the nursing and midwifery council’. Another example of how codes of practise provide specific rules for each situation is the including standards of practise specially tailored for social care workers. This is known as the ‘General Social Care Council.’ The standards of practise must comply with the employers and employees responsibilities non- discriminatory practise. These responsibilities include staff promoting choices about service users and the care they receive; promoting a sense of self – concept for each service user; promoting diversity by considering their preferences, the service user’s individual needs and their wishes being taken into consideration of every aspect of their care. These responsibilities help to promote diversity, because it prevents victimisation and respects individual’s different views, with providing equality for all and promoting non – discriminatory practise. Overall, this piece of legislation is effective, because it aims to promote diversity by providing important legislation with lawful regulations that helps to meet service user’s needs. For example, the mental health act ensures the individual focused on if necessary, will be ensured to have informed and respectful decisions made based on their needs and preferences. Codes of practise are effective for aiming to promote diversity, because they provide standards of practise for individual situations, which all consequently aim to promote diversity and help staff and carers to use non – discriminatory practices that respect all individual service user’s needs while also aiming to promote and respect differences within each individual.

South India and Maharashtra Essay Example for Free

South India and Maharashtra Essay Maharashtra is a state in the western region of India. It is the second most populous state after Uttar Pradesh and third largest state by area in India. Maharashtra is the wealthiest state in India, contributing 15% of the countrys industrial output and 13.3% of its GDP. Maharashtra is bordered by the Arabian Sea to the west, Gujarat and the Union territory of Dadra and Nagar Haveli to the northwest, Madhya Pradesh to the north and northeast, Chhattisgarh to the east, Karnataka to the south, Andhra Pradesh to the southeast and Goa to the southwest. The state covers an area of 307,731 km2 (118,816 sq mi) or 9.84% of the total geographical area of India. Mumbai, the capital city of the state, is Indias largest city and the financial capital of the nation. Maharashtra is the worlds second most populous first-level administrative country sub-division. Were it a nation in its own right, Maharashtra would be the worlds twelfth most populous country ahead of Philippines. Etymology The modern Marathi language developed from the Maharashtri Prakrit,[7] and the word Marhatta (later used for the Marathas) is found in the Jain Maharashtri literature. The terms Maharashtra, Maharashtri, Marathi and Maratha may have derived from the same root. However, their exact etymology is uncertain.[8] The most widely accepted theory among the scholars is that the words Maratha and Maharashtra ultimately derive from a compound of Maha (Sanskrit for great) and rashtrika.[8] The word rashtrika is a Sanskritised form of Ratta, the name of a tribe or a dynasty of petty chiefs ruling in the Deccan region.[9] Another theory is that the term is derived from Maha (great) and rathi or ratha (great chariot driver), which refers to a skillful northern fighting force that migrated southward into the area.[9][10] History The Nashik Gazetteer states that in 246 BC Maharashtra is mentioned as one of the places to which Mauryan emperor Asoka sent an embassy, and it is recorded in a Chalukyan inscription of 580 CE as including three provinces and 99,000 villages.[11][12] The name Maharashtra also appeared in a 7th-century inscription and in the account of a Chinese traveller, Hiuen-Tsang.[11] In 90 AD Vedishri,[13] son of the Satavahana king Satakarni, the Lord of Dakshinapatha, wielder of the  unchecked wheel of Sovereignty, made Junnar, thirty miles north of Pune, the capital of his kingdom. It was also ruled by Kharavela, Satavahana dynasty, Western Satraps, Gupta Empire, Gurjara-Pratihara, Vakataka, Kadambas, Chalukya Empire, Rashtrakuta Dynasty, and Western Chalukya before Yadava rule. Maharashtra was ruled by the Maurya Empire in the 4th and 3rd century BC. Around 230 BCE Maharashtra came under the rule of the Satavahana dynasty which ruled the region for 400 years.[14] The greatest ruler of the Satavahana Dynasty was Gautamiputra Satakarni. The Chalukya dynasty ruled Maharashtra from the 6th century to the 8th century and the two prominent rulers were Pulakesi II, who defeated the north Indian Emperor Harsha and Vikramaditya II, who defeated the Arab invaders in the 8th century. The Rashtrakuta Dynasty ruled Maharashtra from the 8th to the 10th century.[15] The Arab traveler Sulaiman called the ruler of the Rashtrakuta Dynasty (Amoghavarsha) as one of the 4 great kings of the world.[16] From the early 11th century to the 12th century the Deccan Plateau was dominated by the Western Chalukya Empire and the Chola dynasty.[17] Several battles were fought between the Western Chalukya Empire and the Chola dynasty in the Deccan Plateau during the reigns of Raja Raja Chola I, Rajendra Chola I, Jayasimha II, Somesvara I and Vikramaditya VI.[18] In the early 14th century the Yadava dynasty, which ruled most of present-day Maharashtra, was overthrown by the Delhi Sultanate ruler Ala-ud-din Khalji. Later, Muhammad bin Tughluq conqu ered parts of the Deccan, and temporarily shifted his capital from Delhi to Daulatabad in Maharashtra. After the collapse of the Tughlaqs in 1347, the local Bahmani Sultanate of Gulbarga took over, governing the region for the next 150 years. After the break-up of the Bahamani sultanate, in 1518, Maharashtra split into and was ruled by five Deccan Sultanates: namely Nizamshah ofAhmednagar, Adilshah of Bijapur, Qutubshah of Golkonda, Bidarshah of Bidar and Imadshah of Berar. These kingdoms often fought amongst each other. United, they decisively defeated theVijayanagara Empire of the south in 1565. Also present area of Mumbai was ruled by Sultanate of Gujarat before capturing by Portugal in 1535 and Faruqi dynasty ruled Khandesh region between 1382 and 1601 before Mughal annexation. Malik Ambar was the regent of the Nizamshahi dynasty of Ahmednagar from 1607 to 1626. During this period he increased the strength  and power of Murtaza Nizam Shah and raised a large army. Malik Ambar is said to be the one of proponent of guerilla warfare in the Deccan region. Malik Ambar assisted Shah Ja han wrestle power in Delhi from his stepmother, Nur Jahan, who had ambitions of seating her son-in-law on the throne. By the early 17th century, Shahaji Bhosale, an ambitious local general in the service of the Mughals and Adil Shah of Bijapur, attempted to establish his independent rule. His son Shivaji succeeded in establishing Maratha Empire which was further expanded by Bhonsle of Nagpur, Gaekwad of Baroda, Holkar of Indore, Scindia of Gwalior and Peshwas (prime ministers). The Marathas defeated the Mughals, and conquered large territories in Northern and Central parts of the Indian subcontinent. After the defeat at the Third Battle of Panipat in 1761, the Maratha restored their supremacy and ruled central and north India including New Delhi till the end of the eighteenth century. The Third Anglo-Maratha war (1817–1818) led to the end of the Maratha Empire and East India Company ruled the country in 1819. After Indias independence, the Deccan States, including Kolhapur were integrated into Bombay State, which was created from the former Bombay Presidency in 1950. In 1956, the States Reorganisation Act reorganised the Indian states along linguistic lines, and Bombay Presidency State was enlarged by the addition of the predominantly Marathi-speaking regions of Marathwada (Aurangabad Division) from erstwhile Hyderabad state and Vidarbha region from the Central Provinces and Berar. Also, southernmost part of Bombay State was ceded to Mysore one. From 1954–1955 the people of Maharashtra strongly protested against bilingual Bombay state and Samyukta Maharashtra Samiti under the leadership of Dr. Gopalrao Khedkar was formed. Mahagujarat Movement was also started for separate Gujarat state. Gopalrao Khedkar, S.M. Joshi, S.A. Dange, P.K. Atre and other leaders fought for a separate state of Maharashtra with Mumbai as its capital. On 1 May 1960, following mass protests and sacrifice of 105 human lives the separate Marathi-speaking state was formed by dividing earlier Bombay state into new states of Maharashtra and Gujarat. The demand of the local people of merging some of the Marathi speaking areas of Karnataka namely Belgaum, Karwar and Nipani is still pending. Geography Maharashtra encompasses an area of 308,000 km ² (119,000 mi ²), and is the  third largest state in India. It is bordered by the states of Madhya Pradesh to the north, Chhattisgarh to the east, Andhra Pradesh to the southeast, Karnataka to the south, and Goa to the southwest. The state of Gujarat lies to the northwest, with the Union territory of Dadra and Nagar Havelisandwiched in between. The Arabian Sea makes up Maharashtras west coast. Pune is located at the confluence of theMula and Mutha rivers. The Western Ghats better known as Sahyadri, are a hilly range running parallel to the coast, at an average elevation of 1,200 metres (4,000 ft). Kalsubai, a peak in the Sahyadris, near Nashik City is the highest elevated point in Maharashtra. To the west of these hills lie theKonkan coastal plains, 50–80 kilometres in width. To the east of the Ghats lies the flat Deccan Plateau.

Behaviour of Termites: Breeding and Effects of Repellents

Behaviour of Termites: Breeding and Effects of Repellents Introduction and Review of Literature General biology of termite Termites are social insects that live in colonies, which, in turn, function because the complementary roles played by the different caste. In United States, subterranean termites, Coptotermes spp. and Reticulitermes spp. are the most destructive and cause substantial economic damage to buildings/structures (Su Scheffrahn 1990). A population of subterranean termites is comprised of distinct colonies. Colonies may occupy underground networks that link several foraging sites (Thorne Breish 2001). Termite foraging behavior The nutritional ecology of termites has played a significant role in shaping their evolution and ecology organization (Thorne, 1999). To understand colony structure and the organization of foraging termites, it has been necessary to map both nest and feeding sites, frequently using behavioral assays of aggression to ascertain the colony affinity of a given nest or group of workers occupying a food source (Long Thorne 2006). Also, dye indicators and mark release recapture studies have been developed to attempt to census colonies, determine colony boundaries, and plot the distribution of foragers and other spatial aspects of resource use (Su et al. 1984, Forschler Townsend 1996, Thorne et al. 1996, Abdul Hafiz et al. 2007). Studies of termite foraging range generally offer statistic description of colony nest and satellite sub nest distribution and sometimes reveal the temporal dynamics of foraging range expansion and territorially, similar to what has been described in ants. Colony structure and the spatial organization of foraging in termites are, nevertheless, poorly understood in comparison to other social insects. The cryptic nesting and foraging habits of subterranean termites have hindered our understanding of many important features of their population biology, especially the distinctness of colonies and the breeding system within colonies. Their cryptic foraging and nesting habits, many features of subterranean termite biology have been difficult to study by using the traditional methods of field investigation. The main obstacle has been a lack of practical methods for delineating large numbers of colonies (Long Thorne 2006). Termite control Chemical and physical barriers to prevent them from reaching wood construction are two basic methods that have been used to control termites. Currently, insecticides used for termite control can be categorized into three groups, organochlorine, cyclodiens, which are being phased out of use because of potential damage to the environment and human health; pyrethroids, which considered not effective because of their repellency and short residual life in soil; and new termiticides that are considered as non repellent and slow acting termiticide (Potter and Hillary 2003). Remedial control is extremely difficult with acutely toxic chemicals because termites avoid area with dead termites, preventing any further contact with the toxicant. For the Formosan subterranean termites, remedial control using slow-acting toxic baits is are more acceptable method than the use of acutely toxic insecticides. Sub lethal insecticide exposure may be expected to influence insect behavior because most insect icides attack the nervous system resulting in detection by insects, distruption of physiological processes, and behavioral resistance (Haynes 1988, Silverman and Bieman 1993). The purpose of applying insecticides to soil proximal to a structures foundation of a continuous insecticide barrier in soils under and around the structure (Kamble, 1991). This barrier may be created by using either pre or post construction techniques. Post construction insecticide application technique include void treatments, soils trenching, sub slab injections, and soil rodding application. Chemical and physical barriers to prevent them from reaching wood construction are two basic methods that have been used to control termites (Abdul Hafiz et al. 2007). Remedial control is extremely difficult with acutely toxic chemicals because termites avoid area with dead termites, preventing any further contact with the toxicant. Sub lethal insecticide exposure may be expected to influence insect behavior because most insecticides attack the nervous system resulting in detection by insects, disruptions of physiological processes, and behavioral resistance (Haynes Baker 1988, Silverman Bi eman 1993) Non repellent termiticide Termiticide that do not repel termites from penetrating into treated soil but rather successfully kill them were recently registered in the United States (Kard 2003) and other parts of the world. They have become popular alternatives to conventional repellent soil-poisoning agents (Shelton and Grace 2003). Nonrepellent termiticides have been shown to be effective for the elimination of termite infestations when applied around the exterior perimeter of the building (Potter Hillary 2001) New generations of termiticides which contain imidacloprid (Premise ®), fipronil (Termidor ®) and indoxacarb, chlorfenapyr (Phantom ®), Chlorantraniliprole are used as soil-applied or by direct injection in the colony, posed lethal effects to subterranean termite (Osbrink Lax 2003; Kamble Davis, 2005; Hu et al., 2005; Spomer et al.,2009). The advantages of these new termiticides are slow-acting and non-repellent. Thus, termites cannot detect these termiticides when applied in to the soil or when used on filter paper in the laboratory. The transfer effect of imidacloprid, fipronil and indoxacarb among termite workers was studied by researchers and results showed that the termites were able to transfer the termiticides from the treated termites (donors) to the untreated termites (recipients) (Kard 2003, Thorne and Berisch 2001, Vargo Parman 2004, Tomalski and Vargo 2005, Hu et al. 2005, Shelton Grace 2006; Spomer et al.,2009). Termite baiting Baiting for suppression or elimination of subterranean termites is not a new idea. The ultimate goal of termite baits is to eliminate termites from structure (Su 1994, Su et al. 2000). Recently, hexaflumuron baits have successfully been applied to control the field colonies of Coptotermes spp. and Reticulitermes spp. (Su 1994, Su et al. 2000). At the same time Nouviflumuron also have been widely used in termite baiting. In laboratory trials in which R. flavipes were fed radiolabeled noviflumuron or hexaflumuron, noviflumuron demonstrated significantly faster speed of action, greater potency, and nearly 4-fold slower clearance from termites compared with that of hexaflumuron (Sheets et al. 2000; Karr et al. 2004, Spomer Kamble, 2006). Primer pheromones (Wilson Bossert, 1963) are chemical messengers that can be passed among individuals, thereby triggering a physiological response in a recipient. In termites, JH is one such primer pheromone (Henderson 1996); it includes presoldiers differentiation from workers at excessively high titer. The differentiation of the soldier caste, a development end point, in respond to JH is indirect in maintaining immature features in all other non social insects (Henderson, 1996). In the last decade there has been a dramatic increase in the research on and the development of bait systems for termite management. The increasing availability of bait systems for the control of active termite infestations is already significantly affecting termite management practices in many part of the world. There is even discussion of using such system as standalone measures for the long- term protection of a structure (Su et al. 2001; Grace et al. 1996). Even though these important and remarkable trends, baiting is developing technology, and many more changes to existing bait technology can be expected (Potter 1997). The bait matrices containing hexaflumuron, a chitin synthesis inhibitor, were most effective in reducing or eliminating foraging populations of Coptotermes formasanus Shiraki and Reticulitermes flavipes Kollar (Su Scheffrahn, 1996, Su, 1994). Molecular genetic marker The application of molecular genetic markers to the field populations of subterranean termite provides a powerful way to discriminate among large numbers of colonies be identified and distinguished from each other. The application of molecular genetic marker to field populations of subterranean termites provides a powerful way to discriminate among large numbers of conspecific colonies in a population as well as to determine colony breeding structure (Husseneder et.al. 2003) Genetic markers provide the most powerful means for delineating the boundaries of colonies and for determining colony affiliation for groups of foraging workers (Thorne et al.1999, Vargo 2003a,b). Microsatellite markers, with their co-dominant nature and high variability, are especially useful for investigation of colony distinctness (Vargo 2003b). Genetic markers are also the most practical way to determine colony breeding structure (Thorne et al.1999, Ross 2001), and there have been a growing number of genetic studies of breeding systems in termites (Luykx 1993, Husseneder et al. 1997, 1999, Husseneder Grace 2001a, 2001b, Vargo et al. 2003), including some on Reticulitermes spp. (Cle ´ment 1986, Reilly 1987, Jenkins et al. 2002, Bulmer et al. 2001, Vargo 2003b). The most detailed studies to date of the eastern subterranean termite, R. flavipes, are those of Reilly (1987) using allozymes, Bulmer et al. (2001) using allozymes and mitochondrial DNA haplotype data, and Vargo (2003a,b) using microsatellites and mitochondrial DNA sequence data. These studies have revealed variation in colony social organization in R. flavipes from very highly inbred colonies in Tennessee (Reilly 1987), to a mixture of approximately one third simple families and two thirds inbred colonies headed by many neotenic reproductives in Massachusetts (Bu lmer et al. 2001), to three fourths simple families and one fourth inbred families with only a few neotenics in North Carolina (Vargo 2003b). The above studies were conducted in natural areas, and there are no comparable studies performed to date in urban areas around buildings. Colony social organization in R. flavipes may vary in response to local ecological conditions (Bulmer et al. 2001), raising the possibility that for a given geographic area, colonies in urban habitats may differ in their social organization from those in natural habitats. In a study of Reticulitermes Hesperus Banks in southern California, Haagsma and Rust (1995) found differences in colony size, foraging activity, and body weight between colonies in natural and urban habitats. In addition to providing a powerful way to determine colony distinctness and to infer colony breeding structure in subterranean termites, molecular genetic markers are useful for applied studies, such as tracking colonies over time after exposure to an insecticide treatment and determining whether termites that reappear after treatment are part of the originally treated colony or are from a neighboring untreated colony that has moved into the area (Husseneder et al. 2003). Such studies are critical in the evaluation of management practices that target septic colonies and aim to eliminate them or greatly suppress their populations. Genetic/breeding structure population Colony fusion For social organisms, genetic structure assumes additional significant not only for the evaluation of social behavior, but also for the evolution of multiple queen societies, reproductive skew, sex ratio conflict, conflict over growth versus reproduction. Colony fusion has long been a suspected mechanism generating unusual colony genetic structure in termites. Colony genetic structure, reported a lack of genetic differentiation between colonies of Reticulitermes grasseiacross some regions of France and Spain. Together with this genetic data, a lack of distinct nest mate discrimination in laboratory trials (Clement 1986) suggested that colony fusion was widespread in some populations. Although recent studies have failed to corroborate these earlier descriptions of widespread colony fusion in this species (DeHeer et al. 2005), Clements work raised considerable awareness about colony fusion for those working on other subterranean termites. In introduced populations of Coptotermes formos anus, inter-colony aggression is often found to be weak or variable (Husseneder and Grace 2001a, Cornelius Osbrink, 2003) and one mark-release-recapture study described patterns consistent with a colony fusion event (Su and Scheffrahn, 1988). Nevertheless, genetic evidence for colony fusion in this species has remained elusive in spite of the relatively large numbers of colonies which have been assayed (Vargo et al., 2003, 2006; Husseneder et al., 2005). For Reticulitermes flavipes many experimental results have suggested the possibility that colony boundaries were porous. Laboratory agonism studies (Grace 1996, Polizzi and Forschler 1998, 1999, Bulmer and Traniello 2002, Fisher and Gold, 2003) and field surveys of molecular diversity (Jenkins et al. 2002, Bulmer et al. 2001) both suggested that individuals originating from different colonies may not distinguish between nestmates and non-nestmates, and consequently share the same nests or tunnel systems. However, in contrast to other species of subterranean termites these findings in R. flavipes have been confirmed via more direct assessments of colony fusion (Fisher et al. 2004), including one molecular study that provided a time course of colony genotypes before and after merger (DeHeer and Vargo 2004). Such fused colonies also appear to occur in other groups of termites. The relatedness hypothesis indicates that fused colonies are preferentially formed between groups of related termites because any costs associated with fusion are reduced when relatedness remains high in these colonies. This argument necessarily assumes that such colonies experience some general benefits to increasing their size (Costa and Ross, 2003). The genetic diversity hypothesis posits that increased genetic diversity provides sufficient group-level benefits to offset the costs of decreased relatedness within colonies. The specific benefits of increased genetic diversity could include the same types of benefits hypothesized to occur elsewhere (Schmid-Hempel and Crozier, 1999), in addition to the potential benefit that could result from a reduction in inbreeding. Simple family extend family Subterranean termite colony such as Coptotermes formosanus, generally begin as simple families headed by two primary (alate derived) reproductives that pair after mating (Tamashiro et al. 1987, Raina et al. 2003). As time goes by, the primary king and/or queen will be replaced by varying numbers of neotenics (non alate derived reproductives) from within colony; where this replacement leads to extended families with different degrees of inbreeding depending on the number of reproductives and number of generation of inbreeding (Thorne et.al 1999, Bulmer et al. 2001, Vargo et al. 2006, Husseneder et al. 2007) Bioinformatics/ Computational Molecular Biology Biological database is a large, organized body of persistent data, usually associated with computerized software designed to update, query, and retrieve components of the data stored within the system. A simple database can be a single file containing many records, each of which includes the same set of information (Lewis et al. 1995). For example, a record associated with a nucleotide sequence database typically contains information such as contact name, the input sequence with a description of the type of molecule, the scientific name of the source organism from which it was isolated, and often, literature citations associated with the sequence. The term of Bioinformatics meaning the application of information technology to the field of molecular biology. Bioinformatics currently contains the creation and advancement of databases, algorithms, computational and statistical techniques, and theory to solve formal and practical problems arising from the management and analysis of biological data (Hogeweg1980). Over the past few decades rapid developments in genomic and other molecular research technologies and developments in information technologies have combined to produce a tremendous amount of information related to molecular biology. It is the name given to these mathematical and computing approaches used to glean understanding of biological processes. Common activities in bioinformatics include mapping and analyzing DNA and protein sequences, aligning different DNA and protein sequences to compare them and creating and viewing 3-D models of protein structures (Huang 2004) Bioinformatics focus on developing and applying computationally intensive techniques (data mining, machine learning algorithms, and visualization) to achieve this goal. Major research efforts in the field include sequence alignment, gene finding, genome assembly, protein structure alignment, protein structure prediction, prediction of gene expression and protein-protein interactions, genome-wide association studies and the modeling of evolution (Huang 2004). In the application of molecular ecology studies of termites, mitochondrial genes were used for taxonomy purpose in termites (Cameron Whitting, 2007). Thus, the whole mitochondrial genome can be used to predict useful regions for further investigation in the multiple alignments methods application. Multiple alignments are the key starting point for prediction of protein secondary structure, residue accessibility, and the identification of residues important for specificity. Multiple alignments can provide the basis for the most sensitive sequence searching algorithms (Barton Sternberg, 1990). Furthermore, methods in multiple alignments affective analysis of a well-constructed multiple alignments can provide important clues about which residues in the protein are important for stabilizing the second and tertiary structure of the protein (Altschul et al. 1997) ClustalW will calculates the best match for the selected sequences, and lines them up so that the identities, similarities and differences can be seen and will provide a better quality for sequences (Thomson et al. 1994). Meanwhile, T-Cofee application is better to overcome with some of the problems that standard hierarchical method s have in aligning sequences of very different length or that share only local region similarity (Notredame et al. 2000). The program works by building a library of pairwise alignments for the sequence interest. Furthermore, T coffee has been adapted to include structural alignment and alignments from threading algorithms since it can work from pairwise alignments that originate from any source (Notredame et al. 2000). In addition, the program PSI-BLAST searches database with a single sequence, any high-scoring sequences that are found are built into a multiple alignment, and this multiple alignment is then used to derive a search profile for subsequent s earch of the database. This process is repeated until no new sequences are added to profile, or a specific number of iteration have been performed (Jones 1999). Research Objectives To test non-repellent termiticide model assay for their ability to induce detectable molecular changes in worker termites e. g., hemolymph proteins their corresponding genes. To infer the colony social organization of R. flavipes in urban habitat based on colony and population genetic structure and to compare this social organization in nearby natural habitat, To track the foraging locations of a large number of Reticulitermes colonies from natural forest (Wilderness Park) over the course of three field seasons using previously developed microsatellites by Vargo (2000). To analyze colony and population genetic structure/breeding system in natural and urban regions in order to determine the prevalence of neotenic reproduction and improve our understanding of the factors facilitating the spread of subterranean termites to new urban areas To determine the termite colony either a simple colony or extended colony using molecular ecology methods and also to determine if the colony undergo any kind of colony fusion To delineate the genetic structure of swarm aggregations of alates in order to infer potential mechanisms leading to inbreeding avoidance that do not require kin recognition. To utilize bioinformatic/molecular computational biology application tools to analyzing data at molecular level using BLAST, Clustal X, TCofee for sequencing analysis, pairwise/multiple alignment to study colony breeding structure of R.flavipes MATERIALS AND METHODS Termite Collection Sampling Reticulitermes flavipes, the Eastern subterranean termite, will be collected from locations within Wilderness Park Recreational Area, Lincoln; NE. Twenty workers will be sampled in each collection point located every 20 m along two intersection transects. The termites will be maintained on moistened corrugated cardboard and only 3-5th instar worker termites will be used for the study. Detection of fused colonies In order to detect colonies that had undergone fusion, collections of termites from large numbers of established colonies of R. flavipes will be collected between May 2009 and October 2011. At each location, minimum of 20 adult workers in 95%ethanol from multiple feeding sites, and mapped the locations of these feeding sites relative to one another using compass and measuring tape (DeHeer and Vargo, 2004). Samples will be stored in alcohol at 480C until DNAisolations could be performed. Microsatellite genotyping (Fusion Inbreeding) Using the Puregene DNA purification kit (Gentra systems, Minnepolis MN, www.gentra.com), genomic DNA will be isolated from each of 20 whole worker bodies from each of the feeding sites. At the location, minimum of 20 adult workers in 95% ethanol from multiple feeding sites will be collected, and mapped the locations of these feeding sites, and the locations of these feeding sites will be mapped relative to one another using compass and measuring tape. Each genotype individual termites at six different microsatellite loci : Rf1-3, Rf21-1 and Rf24-2 from Vargo (2000) and Rs15, Rs76, and Rs78 from Dronnet et al. (2004). PCR reactions will be setup in 96oC. Well plates in 5ul reaction mixtures containing 1X PCR buffer (Eppendorf), 2mM MgCl2, 0.2 mM of each dNTP, 0.2 U Taq polymerase (Eppendorf), 0.4 pmol of forward primer. Forward primers will be labeled with IRD 700 fluorescent dye (LI-COR), and samples were run on Li-Cor 4200L automated sequencer. Gel image will scored manually on Adobe Photoshop 7.0 by comparison to a size ladder. Colony affiliations To determine colony affiliation of the collection points, methods of other studies will be followed. Testing all pairs of collection points within each species for genotypic differentiation by means of a permutation test by using the program FSTAT (Goudet 2001). Pairs of collection points that will be significantly differentiated will be grouped into the same colony Morphology Scanning electron microscopic pictures (coronal and profile views) will made of the heads for each species) and will be studied using a binocular microscope to evaluate the profile of the post clypeus. Colour of the tibia of reproductives will be noted because this feature is an informative morphological indicator in association with the postclypeus profile. Genetic Data Analysis/ Simple or Extend Colony (Breeding Structure) The collection points will be analyzed to determine belonged to the same colony. The genotypic frequencies between all pairs of collection points by means of a log-likehood (G) based test of differentiation using the program GENEPOP on the Web (Raymond Rousset 1995; http://genepop.curtin.edu.au/). The overall significance will be determined via Fishers combined probability test. G-test analysis will be performed with collection points over the large scale with multiple collection points within the extensively sampled sites and finally among the colonies from each population to verify genetic differences will be used. Colonies will be classified as simple families when workers had genotypes consistent with being the direct offspring of one pair of reproductives and when the observed frequencies of the genotypes did not differ significantly from those expected under Mendelian segregation of alleles from two parents. Significance will be determines by a G-twst (P Colonies will be classified as extended families when the genotype distributions within colonies were not consistent with being produced by a single pair of reproductives (e.g more than four genotypes at a locus or three or more homozygote genotypes) or genotypes frequencies deviated significantly from those expected in simple families. Genetic relatedness among workers will be estimated for each colony and averaged over colonies for the same site will be using the computer program RELATEDNESS 5.00 (Queller Goodnight 1989) Inbreeding-adjusted estimate of relatedness r* that better reflects the number of reproductive presents in each colony by using Pamilo (1985) formula R*= r- [ 2FIT /(1+FIT)]/ [1-2FIT/(1+FIT)] I,C,T representing different colonies The breeding system and genetic differentiation among colonies will be investigated with hierarchial F statistics, assuming the infinite allele model and with individuals nested in colonies. The hierarchical analysis will be performed with F-stat program. It will be investigated whether there will be isolation by distance (a positive correlation between genetic differentiation and geographical distance) by calculating Fst between pairs of collection points within large colonies using the programe FSTAT 2.9.3.2 and by testing the significance of correlation between FST/(1-FST) and logarithm of geographical distances with MANTEL test (Mantel 1967). Computer program GENEPOP, with 10 000 permutations and the Mantel correlation coefficient r can be obtained with MANTEL (http://life.bio.sunysb.edu/morph/soft-mult.html) Estimating Colony Foraging Area Termite collected at a sampling point will considered to be affliated with a given colony if Fct, which measured genetic differentiation between collection points, will not significantly different from zero (i.e., 95% confidence interval did not overlap with zero. Fct will be measured between all possible combinations of collection points pair at each site. Variation in mitochondrial DNA markers will be provided additional support for colony designation (Bulmer et al. 2001). The maximum linear distance between collection points affiliated with the same colony will be used to estimate foraging range. For colonies that will be composed of three or more collection points (n+4), will be estimated the area encompassed by non intersecting lines drawn between collection points and adjusted so it did not overlap with neighboring collection points affiliated with different colonies. Swarming trap The swarm aggregation of alates will be collected alive with light traps. The traps consisted of buckets with a battery operated black light attached to attract the alates. Flight Observation Sticky trap will be used to monitor the dispersal flights of these species, which, in hindsight, may help explain some of the differences in how they are genetically structured. In addition their emergence and landing location. Sex ratio Sex ratio in swarm aggregations were tested for significant deviation from 1:1 using Binomial tests. Swarm aggregations were tested for significant genotypic differentiation with log likehood G Statistics using FSTAT 2.9.3.2 Bioassay Genetic mutation/change after being exposed to non repellent termiticide The concentrations were 0.001, 1.00, 10,100 and 1000 ppm for fipronil, imidacloprid and indoxacarb. In addition, distilled water was used as control for each termiticide. The method used for treatment was described by Hu (2005). Five kilograms of soil were collected from the site of the subterranean termite C. gestroi colony. The soil was then oven-dried. One kilogram for each termiticide was sieved and subsequently divided into six parts. The soil was placed in 100g increments into self-sealing plastic bags for treatment. Ten milliliters of the five concentrations of, fipronil, imidacloprid and indoxacarb will be added to the 100 g bag of soil for testing. The bags were sealed and allowed to mix thoroughly. The soil will be removed from the bags and placed in plastic bags (12 by 115 cm). The termiticide-treated soil was air-dried in a hood for ten days to allow solvents in the formulation to evaporate. Treatments were replicated three times using new stock solutions for each replicate. Bioassay design: Bioassay tubes designed by Su et al. (1995) will be used to investigate termite penetration in various thicknesses of termiticide-treated soil (Figure1). At time of testing, dried treated soil will be removed from the hood, placed into plastic bags and 10 ml of water was pipetted into the bags to obtain 10% moisture content. Three (3 cm) wooden applicator sticks were placed at the bottom of the glass test tube (2 by 15 cm), and 7% non-nutrient agar was inserted into the test tube until it rested on the wooden sticks. Oven-dried and sieved soil will be placed into plastic bags and moistened to concentrations of 10% (10ml /100g) to serve as untreated sand in the test designs. A 0.0, 1.0, 3.0, 5.0, or 10cm layer of termiticide-treated soil was centered between two layers of untreated soil (Figure.1). A glass funnel will be used to place the soil in the test tube and a scintillation vial (10ml) attached to the shank of a screwdriver was used to lightly and level the layers of soil. A 5 cm segment of termiticides-treated soil and a 5 cm segment of untreated soil served as control. Additionally, layers of untreated soil at various thicknesses in the bioassay tube will be served as control. The soil segment will be capped with a 1.0 cm core of agar and a 4cm by 4 cm portion of paper towel folded placed on the top of the tube. Eighty C. gestroi workers and five soldiers (20:1) were placed in each test tube to simulate normal termite activity and prevent overcrowding. A piece of aluminum foil will be placed over the top and end of each tube, and will be covered with black plastic container to allow for darkness and prevent desiccation of the termites. Bioassay tubes will be kept at 29 ±1 °C. The experiment was a 6 (concentrations) x 3 (replicates) x 5 (soil thickness) factorial design with concentration and thickness as the main effects. Test tubes will be held vertically in test tube racks with termites at the top of the tube. Observations will be made daily up to one week for the number of worker termite mortality, vertical distance of treated soil penetrated by termites and percentage of penetration into treated soil. The percentage of termite mortality and soil penetration data were subjected to arc-sine transformation before analysis of variance and means were separated with Tukey HSD. Then percentage of penetration into treated soil and the percentage of mortality were analyzed with analysis of variances (ANOVA). Also the percentage of surviving termites located at the bottom of the bioassay unit was analyzed. DNA will be isolated from dead termite to b
