The Human Immunodeficiency Virus ( Hiv ) Essay - 2078 Words
Introduction The Human Immunodeficiency Virus (HIV) is a Lentivirus (a subgroup of retrovirus) that causes HIV infection and over time Acquired Immunodeficiency Syndrome (AIDS). AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive, without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. HIV infects vital cells in the human immune system such as helper T cells (specifically CD4+ T cells), macrophages, and dendritic cells. HIV infection leads to low levels of CD4+ T cells through a number of mechanisms, including Pyroptosis of abortively infected T cells, apoptosis of uninfected bystander cells, direct viral killing of infected cells, and killing of infected CD4+ T cells by CD8 cytotoxic lymphocytes that recognize infected cells. When CD4+ T cell numbers decline below a critical level, cell-mediated immunity is lost, and the body becomes progressively more susceptible to opportunistic infections. Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, and breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells. Medical technology is one of the professions that is very prone to accidental exposure to this blood borne pathogen due to their nature of work.

Drugs Are Bad, Mââ¬â¢Kay. Drug Trafficking Is A Very Serious
Drugs are bad, mââ¬â¢kay. Drug trafficking is a very serious problem. Simple solutions such as legalization of the drugs to prevent all problems and taxing it to make money off of would be common sense but it doesnââ¬â¢t happen. I know that some drugs arenââ¬â¢t illegal in some states and countries but it hasnââ¬â¢t turned into a problem for them. I am curious to know more about how it affects the economy, why people do it, and what are resolutions for the issue. Most countries have to deal with it everywhere. It has evolved the world into a dangerous violent criminal world. Unfortunately, this type of ââ¬Å"businessâ⬠leads to tons of constant kidnapping, prostitution, murders, and plenty of other crimes that we don t hear much of. Yet, it is a fast andâ⬠¦show more contentâ⬠¦In the article, Transporting Cocaine, it states ââ¬Å"Colombian cartels would pay the Mexican groups as much as $1,000 per kilogram to smuggle cocaine into the United Statesâ⬠(Schmidt, 2). Then Colombian cartels would then pick up the drugs and resume distribution and sales efforts, making personal profits that are unrecorded. Therefore the growing informal drug economy leads to many individuals creating a substantial living through this undercover market. According to up to date studies and statistics, the united states of america is the largest buyer of the illegal drugs in the world. Hundreds of tons of the drugs and narcotics are being ingested b y american citizens daily. The coast guard can only seize a fraction of the amount of products that make it in the us. These individual drug cartels monopolizing the trafficking market are a growing problem for the U.S economy and need to be located and controlled. In order to seize these individuals who are growing in power and numbers, the U.S. must control the connections between Mexico and Columbia. Mexico is the biggest transporter amongst Columbia and the U.S. because it shares a border with the U.S. This increasingly influences the drug trafficking leads to drug dealers giving them motives. If this trafficking continues, the U.S. informal economy will crush the growth of legal industries. The trafficking and abuse of drugs in the U.S. affects nearly all aspects of

Portfolio And Is Situated In The Vineyard â⬠Myassignmenthelp.Com
Question: Discuss About The Portfolio And Is Situated In The Vineyard? Answer: Introducation The vineyard is a part of the portfolio and is situated in the vineyard made is first move its first move in, taking this into account for the past few years the organisation have been reworking and redeveloping its strategy with it main goal of maintaining the integrity and viability of the site. The site when it reaches its capacity produces an approximately 1200 tonne of fruits variations which usually range from C-B in quality. The production is influenced by the seasonal change and the requirement of the company. Measurable objective The main objective is the restoration of the underperforming block in the xxx section of the xxx vineyard. In order to regain the performance both the quality components and the production are to be re-established. The main emphasis is the re-establishment of the vibe cordon in the xx vineyard. This would directly influence the overall viability of the block and increase the productivity and the quality of the block (Liu et al., 2016). Current situation Putting emphasis on the block which has declined its productivity since the time it has been established. The expectation from the sector was for production rates of thirty tomes with it the target of the quality averaging B2 (Fleming Koppelman, 2016). The main influencing factor for the less production of the block is the external influences from the drought which was prolonged over the past season with it the increased pressure from the stress. The Ectype dieback disease was also a factor which accelerated and it resulted in reduce of capability and health (Chevrier, 2016). Putting emphasis on the current situation the overall production has declined to an average which is less than fifty percentages with emphasis on the target which was expected in the past five vintages (Nicholas Steyn, 2017). Problem/ opportunity statement The site had started a program termed as continuous improvement which mainly ensures that the vineyard products and viability are aligned with the necessary changes which are required to ensure the sustainability within the strategic planning of the organisation (Turner, 2016). Keeping pace with the external environment was considered as the continuous focus. Putting emphasis on the current situation of oversupply of low grade chardonnay products in the organisation, it can be estimated that this is the best time to undertake the indicated project (Meredith Mantel, 2017). Critical assumption and constraints The general assumptions are: Site personnels should undertake all the labour components, for this project there would not be any contract labours. No additional equipment would be required with regards to the external sources as all the equipment are supplied by the xxx site. To order to ensure training shift work may be incorporated which are subjected to noise from equipment, spray application and injury from the vehicle of operartion (Kerzner, 2017). From the actual budget no greater than five percentages can increase. The working hours would be from 00am to 4.00pm The implementations of the HSE requirement are to be implemented with all personal with ensuring appropriate procedures. The utilization of the existing employee should be done. These have to be implemented within 200 meters of the site of the project When mechanical engineers are in operation no personals are to involve in their working within the site of the project. Analysis of options and recommendation The main aspect for the site management is the undertaking of the analysis which in the motive of removing the existing vines and with emphasis on the block with redeveloping them from the initial stage. The overall cost of the project can be considered as minimal when it is balanced with the return of the financial aspect with regards to the site in the current over supply of the industry. Recommendation 1: the site has additional blocks which in the near future can need modification and this approach of the modification is proposed in existing business plan. Recommendation 2: reworking of the xxx block as an option which can be considered as a alternative option that would directly reduce the initial cost and with it, it would involve earlier Return on Investment (ROI) that is expected from the redevelopment. Recommendation 3: instead of capital budget the site can be processed under the existing budget of the site operation. This has been significantly reduced sue to the consolidation process of the organisation. Preliminary project requirement Fortnightly status report This has to be completed by the project manager and it has to be submitted to the Regional manager on a time period of two weeks. The report include mainly: Summary of the work completed Cost to date Actual cost verses budget (Chevrier, 2016). The report would also summarise other important issue and furthermore unscheduled work which has to be completed during the next upcoming month. The major aim of this project is the achievement of the eighty percent cordon wire fills. Budget estimate and financial analysis The variance should not be greater than 5% from the actual estimated budget Labour is the major element of cost and inputs can be considered as the minimal cost. With the project all the associated cost should be undertaken within the xxx vineyard budget of operation. Input supplied through issue related to stock are termed as indirect cost, these are to be coded to the workshop site at the end of each month calendar. Costs which are termed as additional budget which are outside the allocation of the budget are to be carried out by the consolidated budget cost. The budget would consist of only expenditure only; it should not involve any financial return which is faced during the life cycle of the project (Harrison Lock, 2017). Schedule estimate External factors such as weather and environment may directly impact on the schedule of the project and the completion date. This can be considered as a major issue related to the estimation of the time of the project but however the budget constraints are not affected by this mean. No allowance is made for the delay in the work due to conditions of adverse weather conditions. Labour breakdown Task Total hours String typing to new cordon wire from existing vine truck 216 Vine training anticipated foliage manipulation 1104 Herbicide application as determined by the management for the project 32 Fungicide application as determined by the project management 32 slashing that have to be undertaken which are committed before personnel to time task time 48 Potential risk With regards to the project there are risk analyses which are included in the project. There are various potential risks which can affect the project. Adverse weather: the impact of the weather can be considered as a potential risk but there is no such impact which is done through it (Harrison Lock, 2017). Although if prolonged were condition is encountered, some delay to the completion data could be estimated. Strike recovery rate: expectation of good recovery with vines are expected, this is main due to the factor that the vines are in reasonable health and condition at this time which are reasonable. Personnel Injury: a very good safety record is always connected with the site. All personnel have been involved with raining and inducted have been provided. There can be many unexpected risk which can be related to case of snake, trips/falls and wire breakage (Kerzner, 2017). Quality Substandard: with regards to the personnel full training have been provided to them, task which are similar to them have been in corporate with them and quality assurance have to be checked in regular interval Conclusion The project will be setting a new bench mark with regards to the region with mainly analyse of quality objectives and analysis of yield. The experience and the trials have directly shown that the project would be viable option in order to pulling out vine and the cost of the subsequent in order of developing a block from the stage of initiation. The aspect of financial benefit has been seen in the long term prospective and as stated with the financial return will not be seen. The project would be closely monitored with the aspect of fortnightly report in order to keep the management up to date with the associated issue and progress. With the completion of the project there would be a final project report which would be beneficial in the areas which are likely to be improved when undertaking similar projects like this. The sight has been proactive in aligning their goal which is strategic goal with those outside the organisation or inside the organisation. This is mainly supported by annual business plan which is submitted in the previous year. Thus the organisation is planning in a big deal to get the plot under production which can be directly be involved in the plot can be very much beneficial in order to increase the whole productivity process of the organisation.

Reflexive verbs can also be used to express an action in which two or more people do the action to each other, for example, Ellas se miran, or they look at each other. Imperative Mood (Commands)Words in imperative mood (more commonly known as commands) are something that orders a person or group of persons to take an action. They are similar to other verbs and are taken from the other ver bs. They are not conjugated except for singular, or plural commands. Singular command being one that commands only one person, and a plural command commands a group of people. Reflexive verbs also may be used as commands. There are five irregular commands which do not follow the pattern that is set by the commands before it. Polite CommandsTo congugate a not irregular, polite command. 1. Take the first person congugation of the verb (i.e. cantar canto)2. Remove the o from the end of the verb. 3. If an AR verb add e to the end, if an ER or IR verb, add a to the end. 4. If the command is plural, add an n to the end of the verb. 5. If the command is reflexive add an se to the end of the verb, then place an accent mark over the originally stressed vowel. 6. If the command is negative place a no before the verb7. If both negative and reflexive, move the se before the verb (as a separate word), also, remove the added accent mark. 8. If the original verb ended with a CAR, make the C in the new verb a QU. 9. If the original verb ended with a GAR, make the G in the new verb a GU. 10. If the original verb ended with a ZAR, make the Z in the new verb a C. 11. You may place an usted (for singular) ustedes (for plural) lafter the verb, but it is not necessary. 1. Locate the verb on the chart below, then use the appropriate form of the verb.

If the command is negative, place a no before the verb. 3. You may place an usted (for singular) ustedes (for plural) lafter the verb, but it is not necessary.

The crop protection industry Essay Example
The crop protection industry Essay Example The crop protection industry Essay The crop protection industry Essay The AHP firm Cynamid was purchased by German based company BASF in 2000. This purchase results in a reduction of the competitive ability of AHP and increases the threat posed by BASF. Previously Monsanto had entered agreements with Cynamid in which they were able to sell glyphosphate for use in the herbicide created by Cynamid called Extreme. This increase in the products ability to provide protection is an example of Cynamids focus strategy, providing particular customers with their specific needs. BASF is a major power in the pharmaceutical organisation with many branches into different areas of research. While this draws on its resources it also provides substantial revenue for RD which is essential in the biotechnology industry. More recently BASF claims to be aiming to remain the worlds leading chemical company. (Dorothe Myer 2005) They intend to do this by helping customers and providing sustainable development. While farmers who purchase technologies may want to produce the best yields they also want their customers to be happy with their products. For this reason the strategy BASF is adopting is appropriate for achieving future profits. Monsanto focuses its business on agricultural crop growers. It exceeds in this industry and has obtained a large amount of revenue due to its creation of the Roundup herbicide. Novartis is not completely concerned with crop protection but concentrates on health products. It does not focus solely on crop protection and I dont believe they pose the most significant threat to the market share of Monsanto. BASFs firm Cynamid has developed products that directly impact Monsantos market share. The organisation accumulates large revenues each year and through this revenue can spend more on RD then less successful companies. These revenues are spent over a number a more substantial area as BASF is involved in more industries then crop protection. I dont believe that they are the most significant threat to Monsanto as they have just acquired Cynamid and are not as established as some other organisations in the crop protection industry. DuPonts firm Pioneer focuses on crop protection and in the past has developed useful and profitable products using Monsantos glyphosphate ingredient. Although it has proved competitive it has used Monsantos technology to its advantage and has increased profits partly due to Monsantos patent conclusion. Pioneer is still a threat but I do not believe it is as much a threat as the established Syngenta organisation. Syngenta is another competitor of Monsanto that focuses solely on crop protection. It is a greater threat to Monsanto as it has worldwide operations with high revenues and continually innovative products. Syngenta had sales in 2004 equal to approximately US$7. 3 billion. (Syngenta 2005) It has also been granted recent court ruling that allow it to enter markets and compete with Monsanto. (Corey Gillam 2004) Syngenta is also responsible for releasing a new combination product called LOMAX which provides season long control of broadleaf weeds and grasses. (Syngenta2005) I believe Syngenta has the resources to create innovative products and threaten any thoughts of a monopoly by Monsanto. It is a well established organization with the revenue and technology to expand in the crop protection industry.

International Financial Manager
International Financial Manager International Financial Manager The financial manager of IKEA store in Abu Dhabi is James McGowan His role as a financial manager is to envisage the close supervision of the work performed by the finance staff including day to day contact with the banks to check in level of payments made per day and to transact the payment of materials and external credits through the bank. He is the one responsible for the production of all management reports including monthly financial management report. He budgets for IKEA store annually reforecast periodically. In the process of all these, he operates financial tasks like setting and varying all the internal credits limits and funding employees. He assures cash creditors by paying them on time and prepares payment for the distributors He also liaises with professional advisors like auditors and oversees the works performed by infrastructure developers and ensures timely reporting of results and payment. The financial manager is focused and has more that ten years of experience since he has served as a manager and financial assistant in different firms (Kendrick Vershina, 2005). To manage his financial risks, he has involved the future risks and has made a sport in the banking system so that the company can have a lock-in set exchange rate in the current financial period. He also uses foreign exchange option markets which are managed by global banks. This enables Ikea to purchase options to buy and sell the foreign money they get from the sell of their furniture and other products are sold for them by the institution in future. In the meanwhile he waits so that he would exercise the selling option depending upon the changes of market values against the U.S dollar (Bradstreet Corporation, 2003). Finally, his last approach to managing and mitigating financial risk is to manage the financial risk is through managing their functional currency of the businesses they have overseas. This takes the form of balance sheet management or income management in that instead of IKEA borrowing locally from Abu Dhabi, they could borrow overseas inform of U.S dollars so that there will be no impact on their balance sheet at the time of payment when other currencies move up or down against the U.S dollar (Bradstreet Corporation, 2003).

How can a BMW franchise create Customer Engagement through Social Research Paper
How can a BMW franchise create Customer Engagement through Social Media - Research Paper Example According to the research findings the reasons behind the utilisation of the social media sites depend upon multifarious factors. Its utilisation may depend upon components such as company profile, products and customers that the company is serving. Social media websites can be considered as a good way through which the dependability as well as the goodwill of a company can be enhanced. People make use of social media sites for certain reasons such as for the purpose of interacting, collaborating, looking for counsel from the experts, disseminating of the multimedia, looking for opinions, contributing reviews as well as entertainment. Most of the people argue the fact that social media tends to bring a new sense of community by permitting them to connect with those who are similar to themselves i.e. like-minded people and people with similar tastes and preferences. A number of people are making use of the social media while initiating purchase decisions. The figure below demonstrates the use of social media by BMW and others and the benefits obtained by it in order to gain higher return on investment. The figure makes it apparent that BMW scores high in terms of revenues earned by making use of the social media. It is a well known fact that the new media environment is featured by interactivity and multi-dimensional communication flows. With the pace of time, the marketing functions have also started incorporating social media in its campaigns. (Yamamichi, 2011). The increased utilisation of social networking sites such as Facebook as well as Twitter in order to market the products as well as the services is gaining huge attention in the recent times. The companies make use of the social media sites as one of the significant communication channels so that they can gain feedback of the consumers. It has been recognised that on-line communities are considered as a vital component of social media since they offer the companies with cross-selling opportunities to v arious user groups sharing the similar platform (Donath, 2004). Social media can offer BMW with immediate feedbacks and present the company with quick indications regarding what is required in order to resolve pertinent issues. In the present times, the companies make use of the social media so that they can improve their marketing schemes. The purpose of social media must be to improve branding of the business of BMW and to increase the popularity of the product. It can be mentioned that the social media must also be utilised for the purpose of tracking the presence of the business online in order to ensure that the clients are not deteriorating the value of the brand (Zwart, Lindsay, Henderson, & Phillips, 2011). Certain authors have stated the fact that one of the main benefits of social media is to identify precisely regarding what the customers are thinking. Businesses also make use of the social media sites in order to increase the sales of the products and the services and in turn to increase the market share (Ali, 2011). Social media makes it easier for the companies to create relationships, position the brand properly and share exciting experiences and information with their customers (National Association of Insurance Commissioners, 2011). Web Users Frequency It has been found that the rate of internet penetration in Europe in the year 2011 had been 61.3% while the world average was 32.7%. Internet penetration in rest of the world has been 28.9%. The figure presented below helps

Thomson Greenhouse Essay Example | Topics and Well Written Essays - 250 words
Thomson Greenhouse - Essay Example These figures show that a the potential new greenhouse would offer a good return on investment and could be paid back relatively fast; however, profitability would have to be increased slightly in order to break even. 3. Thomson Greenhouse has very healthy current and debt ratios, so this means that the firm is able to borrow money easily. Also, productivity is healthy because inventory is replaced only every three months or so. The profitability of Thomson Greenhouse is also very strong, so the long-term outlook is positive. The business is now at the point where it could potentially expand and not be affected too much because of the strong financial position that it is in. 4. If the business was passed to one of the sons then specific organizational roles would have to be given to ensure the future success of the business. Any son that took on business would have to have the desire and commitment to Thomson Greenhouse. On the other hand, if the business is sold to an outsider, what kind of profit will Earl and Lisa make from the sale. The deal would also need to be attractive to the potential

Do you agree that the advertising of alcohol should be restricted to such an extent and how far do you believe any governments should be able to control advertising? Introduction In responses to a mass of alcoholic advertisement appears to catering to adults and youth, governments have paid more attention on this, for example, the Government has pledged to introduce a comprehensive alcohol harm-reduction strategy in 2004, which is likely to place restrictions on drinking advertisement which encourage binge drinking among youth. See more: Ethnic groups and racism essay Does all restrictions or guidelines published by governments like this that playing a part in controlling advertising? This essay will mainly concentrate on why such alcoholic advertisements should be restricted; and to what extent should any governments be able to control advertising. Generally, people drinking because they are happy or not, maybe because they get a raise in their salary, or get a rough patch at work, or just enjoy a night out at pub and so on. Mintels exclusive research confirms that the majority of adults, three quarters in the 2003 survey, believe that there is nothing wrong with drinking in moderation, and far more people drink occasionally-and mostly at home-than do so on a regular basis outside the home(Clark, 2003). As for the youth drinking alcohol, most of them just out of curiosity, or bear heavy burden from not only the economy but also the psychology like experiencing a disappointed love affair. In addition, alcoholic advertisement is found to be fancy and attractive for young people, which leave the impression of fun, or cool if they were drinking. According to health expert saying, since ancient times, drinking alcohol in moderation can be beneficial for our health, especially for red wine or beer, drinking a little per day is very good for preventing cardiovascular disease(Locke, 2011). But how about drinking too much? It may become easy for you to become emotional and suffer greatly from more other diseases, like chronic gastritis, alcoholism. Moreover,statistics show that alcohol-related admissions to hospital in England have topped 1m in a year for the first time. In other areas, up to 70% cases sent to the hospital were related to alcohol, and violence, accident and health issues that relating to alcohol are thought to cause thirty thousand premature deaths a year. Meanwhile, prescriptions for treating alcohol abuse have also risen(Meikle). Therefore, drinking too much is harmful for people both in physically and mentally. So how do people know about alcohol, from which channel? Absolutely, media is the main place for alcohol industry spending their money, it is the main channel for people get new information about alcohol, and it is believe that exposure to alcoholic advertisement can increase consumption and influence peoples attitudes towards alcohol especially for young people as they have not formed the correct understanding of it. In order to prevent the large amount of alcoholic advertising appears on media, over the last few decades, governments have set far stricter guidelines and regulations, in spite of this, the following table will disclose another side. Figure1: main alcoholic advertising expenditure on media, 1998-2003* | |? m |Sales ? m | |1998 |219. 7 |28,301 | |1999 |247. 3 |29,808 | |2000 |228. 6 |31,327 | |2001 |210. 2 |32,637 | |2002 |233. 7 |33,942 | |2003* |114. 7 |34,870** | *January to August **estimate Source: Nielsen Media research/Mintel The figure1 shows the advertising expenditure on alcohol, which discovers that during the 1998-2003, although the cost dropped almost half, the percentage of sales did not change a lot, conversely, it roses every year. According to an Kusserow(2001), who works on alcohol controlling revealed that regulations and standards placed on advertising control are almost invalid. Procedures are hard to follow through each department, the viability and effectiveness of huge criteria still have to be established. So Britain wants to balance of economy and health, the duty is not just the governments, and only depending on the polices of government is not far enough, alcoholic and other related-sectors should be self-regulated. On one hand, it is necessary for government to set out a series of limitations on advertising of alcoholic drinks, such as limiting the timing of advertisements on television, ads can be only allowed to display after 10:00pm, trying to avoid youth from it. Meanwhile, prohibiting the liquor company being the sponsor in sport, as Professor Gilmore(2007) said that the limitations should include alcohol sponsorship in sport as the alcohol was being advertised 24 hours a day. Besides,the contents of advertisement should be restricted, images like violence and potential crime should be forbidden as it is easy for young people doing the same things that shows on television. On the other hand, because of the boundedness of governments control, both public and private sectors have responsibilities to help to set out limitations to restrict its promotion and sales through ads. For examples, clubs and music pubs should abolish the unlimited drinking for a certain time only with the fixed money, people who are too young should not be permitted into this occasion. Besides, the price should be increased to reduce the alcohol consumption. In addition, manufacturer should develop a new production line, as an alternative to replace alcohol. Conclusion Now, alcohol has abounded in UKs society, being consumed by both adults and youth, which forms an unbalanced condition between economy and health. The mass advertising appears on television or networks or other channels is the main selling way. Naturally, to control alcoholic advertising is becoming more and more important in UK. But obviously, the actual effects that caused by governments policy is not big, so alcohol-related sector should play an increasing important part in controlling alcoholic advertising, then it must be more powerful and effectiveness.

Biography of Ernest Hemingway Essays -- American Writers Novelists Ess
Biography of Ernest Hemingway "Certainly there is no hunting like the hunting of man and those who have hunted armed men long enough and liked it, never really care for anything else thereafter. You will meet them doing various things with resolve, but their interest rarely holds because after the other thing ordinary life is as flat as the taste of wine when the taste buds have been burned off your tongue." ('On the Blue Water' in Esquire, April 1936) A legendary novelist, short-story writer and essayist Ernest Miller Hemingway was born on July 21, 1899, in the village of Oak Park, Illinois, close to the prairies and woods west of Chicago. His mother Grace Hall had an operatic career before marrying Dr. Clarence Edmonds Hemingway. While growing up, the young Hemingway spent lots of his time hunting and fishing with his physician father, Dr. Clarence Hemingway, and learned about the ways of music with his mother, who was a musician and artist. He was the second of Clarence and Grace Hemingway's six children. He was raised in a strict Protestant community that tried as hard as possible to be separate themselves from the big city of Chicago, though they were very close geographically. Both parents and their nearby families fostered the Victorian priorities of the time: religion, family, work and discipline. They followed the Victorians' elaborate sentimental style in living and writing. He attended school in the Oak Park Public School system and in high school, Hemingway played sports and wrote for the school newspaper. At Oak Park and River Forest High School, Ernest reported and wrote articles, poems and stories for the school's publications largely based on his direct experiences. Hemingway was awarded the 1954 Nobel Prize for Literature. He was unable to attend the award ceremony in Stockholm, because he was recuperating from injuries sustained in an airplane crash while hunting in Uganda. In July, 1961, he ended his life in Ketchum, Idaho. Hemingway may have been a homosexual in denial. His determination to keep up his manhood's "good name" may have been a decoy to hide his true homosexuality. As a Rolling Stone article notes, his son was in fact gay. Perhaps he got it genetically from his father, Ernest Hemingway. Many things were repeated in that family. Hemingway, the depressed drunk, committed suicide just like his father. However,... ...the death struggle in his mind - it is very explicit in books such as A Farewell to Arms and Death in the Afternoon, which were based on his own experience. Modern investigations into so-called Near-Death Experiences (NDE) such as those by Raymond Moody, Kenneth Ring and many others, have focused on a pattern of empirical knowledge gained on the threshold of death; a dream-like encounter with unknown border regions. There is a parallel in Hemingway's life, connected with the occasion when he was seriously wounded at midnight on July 8, 1918, in Italy and nearly died. He was the first American to be wounded in Italy during World War I. Here is a case of NDE in Hemingway, and I think that is of basic importance, pertinent to the understanding of all Hemingway's work. In A Farewell to Arms, an experience of this sort occurs to the ambulance driver Frederic Henry, Hemingway's alter ego, wounded in the leg by shellfire in Italy. Hemingway touched on that crucial experience in his life ââ¬â what he had felt and thought - in the short story ââ¬ËNow I Lay Meââ¬â¢ (1927): "my soul would go out of my body ... I had been blown up at night and felt it go out of me and go off and then come back".

Pertussis caused by Pertussis toxin
B. Pertussis is a bacterium that is responsible for causing whooping cough. The symptoms and signs develop as a result of action of the Pertussis toxin on the upper respiratory tract (containing ciliated ciliated pseudostratified columnar epithelium). The individual develops several episodes of uncontrollable coughing. The characteristic whoop sound is heard during the cough. It develops especially when the individual is breathing in. The individual also develops fever, diarrhoea and a running nose .Before understanding the mechanism by which the toxin acts (that is a transduction mechanism), it is important that the physiology of transduction is understood. Receptors are present on the surface of a cell which helps it to communicate with its external world. Specific molecules bind with these receptors present in the external environment and are recognised by the cell. Once these molecules bind to the receptors a cascade of intracellular signals may be produced which brings about sev eral processes and actions in the cell.A number of antigens or molecules can be recognised by receptors preset on the surface of the cell, following which signals are transmitted within the cell. The lymphocyte cells can bind with and recognise several antigens (belonging to various microorganism and foreign substances). The receptors which are present on the surface of the lymphocytes are made up of complexes containing multiple proteins. Some of the antigens are capable of binding with receptors present on the surface of the lymphocyte and stimulate them to divide further or differentiate into specific effectors cells having a certain function.Some of the antigens are also capable of brining about death of degeneration of the cell. The receptors present on the two types of lymphocytes may be different from each other and are able to recognise different molecules or antigens. However, in both lymphocytes, the intracellular signal pathway is similar. Ultimately, the nucleus is activ ated and alterations occur in the genes to enable a reaction from the lymphocyte (including gene expression) . Receptors are present on the surface of the cell, where molecules bind, and the cell is able to identify the molecule that has attached.The receptor proteins are able to produce a signal once the molecule has attached to the receptor. This signal is transmitted across the plasma membrane, and brings about intracellular events. Signal transduction is a process by which signals are transformed from one form to another. The transformation of the intracellular signal ensures that the message is transmitted in a forward direction, to its destination. The signal may be transmitted to various portions of the cell and may be also get amplified. Finally, the nucleus receives the intracellular signal and the genetic transcription helps to bring about division of the cell .Most of the studies conducted currently for signal transduction were performed on animals, and only a few are con ducted on human subjects . Hence, a lot need to be studied in the field of signal transduction. In some receptors present on the surface of the cell, once antigens are bound with specific molecules, certain ion channels are opened up and an ionic gradient exists that works as an intracellular signal. In certain other cells, when the receptor combines with the molecule, a change in the protein occurs that causes the cytoplasm to get stimulated, resulting in transmission of intracellular signals.When the receptor combines with the specific molecule, a signal is transmitted that enables the receptors to cluster on the surface of the cell. This clustering results in the receptor producing a very strong signal. The exact manner in which the receptors clustering occur is still not understood. However, if the cell contacts another cell that has several copies of the MHC protein complex, they begin to recognise it and cluster around . The receptors present on the cell, usually bring about i ntracellular signals by stimulating the enzyme protein tyrosine kinase (they add phosphate group to tyrosine residues).The receptors on the cytoplasmic front contain tyrosine kinase that is usually inactive. However, when clustering occurs, they begin to stimulate each other through transphosphorlyation, which further activate the biochemical signalling molecules present in the cytoplasm. On the antigen front of the receptor, no tyrosine kinase is available and hence the cytoplasmic front combines with the tyrosine kinase present in the cytoplasm. During clustering, the enzymes are closer to each other, which help to activate the intracellular signalling mechanism.The biochemical activity of the cell is regulated by phosphorylation of the enzymes and proteins by the tyrosine kinase. Phosphorylation makes certain enzymes active, and once they are dephosphorylated (by the enzyme protein phosphatase), they become inactive. Once an enzyme is phosphorylated, new binding sites are created for the target proteins . Phospholipase C-gamma enzyme is present at the tyrosine receptor or the plasma membrane and can attach itself to phosphotryrosine. This enzyme amplifies and forwards the signal.Once tyrosine kinase gets phosphrylated, the phopholipid is broken down into 2 components, namely DAG and IP3. Many DAG and IP3 molecules are produced from single molecules of PLC-gamma, and in this way the signal gets amplified. The IP3 combines with the receptors present on the endoplasmic reticulum, causing the release of calcium ions, and thus raising the level of calcium intracellularly. The signal is maintained even when the Calcium ions are exhausted, as calcium channels present on the cell membrane are opened and the extra-cellular calcium flows in.The Calcium ion binding protein Calmodulin is also activated that controls the activity of other enzymes present in the cell. The signal is transmitted to the nucleus. DAG on the other hand activates the enzyme Protein kinase C. T hey may act in several mechanisms to finally ensure that the signal has reached the nucleus . Calmodulin also controls the activity of the enzyme adenylate cyclase produced by the human cell GTP-proteins help to transmit the signal from the tyrosine kinase receptors to the nucleus. Ras is the most common type of GTP-proteins.It may be activated once the molecule comes in contact with the receptor. Ras can be bound to GTP or GDP. The GDP form of Ras is inactive compared to the GTP. This inter-conversion is brought about by the enzyme Ras-GTPase. Usually, the GTP-proteins are present in an inactive form and are activated once the specific molecule comes in contact with the receptor. GDP can also be converted to GTP by GEFââ¬â¢s. Activation of GTP-proteins leads to activation of several protein kinases (known as ââ¬ËMAP-kinaseââ¬â¢). MAP-kinase can bring about phophrylation and activation of nucleus transcription .B. Pertussis sticks to the cell with the help of ââ¬Å"filamen tous hemagglutininâ⬠(FHA). The Pertussis Toxin also helps to bind the bacterial cell to the host cell. During the colonization of the bacteria, the toxin plays a very important role in invasion . The substance Filamentous hemagglutinin (FHA) produced by B. Pertussis combines with the receptor integrin present on the plasma membrane. This in turn stimulates increased binding of another portion of FHA with another receptor present on the plasma membrane known as ââ¬Ëcomplement receptor-3ââ¬â¢ (CR-3).In this way as the binding of the B. Pertussis antigen is increased with the receptors present on the plasma membrane, the signal produced is strong . The Pertussis Toxin mainly helps the bacterial cell to attach itself to the epithelium of the trachea. The Pertussis toxin is made up of 5 subunits (obtained through the process of gel electrophoresis), namely S-1, S-2, S-3, S-4 and S-5. In fact, the S-4 component is two in number . The subunit S-4 is present in a larger ratio co mpared to the others.The Pertussis toxin has two components namely, A-promoter (S-1) which brings about the toxin enzymatic activity, and B-oligomer (S-2, S-3, S-4 and S-5), which helps the toxin to bind to the receptor present on the plasma membrane. The Pertussis toxin produces several physiological effects including rise in the lymphocyte count, activating the islet cells to release greater amounts of insulin and exaggerating the effects of histamine. The physiological effects of Pertussis toxin mainly brings about it effect on the G-i component of the adenylate cyclase.The toxin works by ADP-ribosylation of G-i protein provided by the S-1 component of the toxin . Compared to normal stimuli, activation with the Pertussis toxin results in greater accumulation of the cAMP within the cells. Agents that obstruct production of cAMP are inactivated by the Pertussis toxin. When the cell is affected with Pertussis toxin and toxin acts on G-i protein, the responses to various chemotactic agents are reduced, suggesting that G-i plays a very important role in the development of immunity.Transducin is Guanine-protein present in the rods and the cones that activates cyclic AMP-selective phosphodiesterase. ADP-ribosylation of tranducin is also stimulated by Pertussis toxin . By altering the manner in which G-proteins are bound, the bacterial toxin can obstruct the signal transduction process. The toxin brings about ADP-ribosylation of certain alpha subunits of the G-protein component of adenylate cyclase namely G-i, G-o, G-t, G-gust, and G-s is not converted to G-olf. Once G-i is ribosylated, the enzyme adenylate cyclase is reduced increasing the level of cAMP .Once the levels of cAMP are raised, the function of the phagocytic cells is reduced (such as chemotaxis, engulfment, bactericidal action, etc) . The S-1 component of the Pertussis toxin is united with the B-oligomer portion in a non-covalent manner. The B-oligomer portion helps the toxin to attach to the receptor present on the plasma membrane. Without the B-oligomer portion, the S-1 component of the Pertussis toxin is unable to pass through the cell . The S-2 and the S-3 components of the Pertussis Toxin mainly help in adhesion of the cell to the host cells.Ciliated epithelial cells contain a glycolipid that helps the S-2 component to bind, whereas the phagocyctic cells contain glycoprotein that helps to bind the S-3 component . Certain opioid receptors are present on the surface of the cell that is linked with the G-protein receptor family. Once the opioid receptors have been activated by the Pertussis toxin, the G-proteins that are sensitive to the Pertussis toxin (namely G-i and/or G-o) are stimulated. The ADP-ribose portion of the NAD is transferred to the G-i. G-i gets inactivated and does not obstruct adenylate cyclase.The intracellular concentration of cAMP increases because the transformation of ATP to AMP cannot be controlled . This results in generation of an intracellular signal which activates the gene transcription in the nucleus and brings about cell division. Once the opioid receptor has been activated, the enzyme Adenylate cyclase is decreased and the Cyclic AMP levels present in the cell are increased. Calcium channels are repressed and inward flow of potassium ions are stimulated by the opioid receptors. When the opioid receptors were stimulated, neuronal excitability reduced.Opioid receptors activation can also bring about activation of the MAP-kinase. Once this occurs, arachidonate may be released and genes c-fos and jun-B are expressed . BvgA and BvgS proteins help the B. Pertussis to express adhesions, virulence factors and toxins. BvgA appear similar to the regulator component, whereas BvgS appears similar to the regulator and sensory component. This system helps to bring about phosphorylation cascade following sensory inputs. As transmission and receiving can occur in this system, a signal pathway system does exist.The cytoplasmic front of the BvgS autophosphorylates with ATP (r-phosphate portion). BvgA is phosphorylated following transfer of BvgS of the phosphate group to the Asp. Gene expression may occur in relation to phosphrylation of BvgA . The human IL-1 stimulates release of kappa Ig-L by the pre-B Cell lines, IL-2R by the Natural Killer cell Lines and PGE2 by the rheumatoid synvovial cells. However, all these IL-stimulated factors are reduced by the Pertussis toxin, which may be associated the cAMP production.As IL-1 stimulates GTPase activity, Pertussis Toxin brought about a reduction in GTPase activity. Pertussis toxin also stimulated ADP-ribosylation of the enzyme adenylate cyclase in the membrane of cells that are usually activated in cells sensitive to IL-1 . Once the cell is affected with the Pertussis toxin, agents that would otherwise obstruct the collection of cAMP are no longer effective. The Pertussis toxin brings about certain cell transduction mechanism that further enables the cell to be invaded by the microorganism .Many of the bacterial toxins such as Cholera Toxin, E. coli labile toxin and the Pertussis toxin act in the same manner and produce the same effect (that is a rise in the cAMP levels of the cell). However, the symptoms and signs of each of these disorders are different. This is mainly because the target tissues and cells of each of these toxins are different. The Pertussis toxin mainly acts on the epithelium of the respiratory tract causing several symptoms such as whoop, cough, breathing problems and cyanosis .

Ancient Civilization Essay
Ancient Civilizations Essay: Understanding Geography and History Amanda Honors World History Period 2 Mrs. Ocasio October 15th, 2012 People. Mountains. People. Culture. People. Water. Ever wonder why history and geography very often studied together? Well it is because geography has a lot of influence on the worldsââ¬â¢ overall history and how it all connects together. Learning geography is also important in understanding history because people need to know where and how were the locations are and why the civilizations formed there.To continue, all civilizations are connected in some way, from trading to religious beliefs or wars to traditions; some of the civilizations that are going to compared are very similar. That is why the understanding of geography is crucial to the understanding of history because it impacted the development of city-states, caused isolation, and allowed cultural diffusion between the civilizations. To begin, geography impacted the development of many city -states. India and the Nile River Valley had been majorly impacted by the Earths geography in early civilizations.Many rivers flowed through India, which included the Indus and the Ganges Rivers. Most Indian city- states were close to these rivers because the people wanted to be near water making it easier to get excess to it. It was also important for Indians to be near the Ganges River because that river was sacred to them and ââ¬Å"â⬠¦one Indian name for ââ¬Å"riverâ⬠: lok-mata, or ââ¬Å"mother of the people. â⬠(World History Book, page 52). Now the Nile River Valley was very fertile, which made ââ¬Å"â⬠¦farmers take advantage of the fertile land of the Nile Valley to grow wheat and flax, a plant whose fivers were used for clothing. and have excess to water in the dry Egyptian heat. The ââ¬Å"Black Landâ⬠was the rich and irrigated area of the Nile Valley and ââ¬Å"no more than 10 miles wide, lay the ââ¬ËRed Land,ââ¬â¢ a sun-baked desert that s tretches across North Africa. â⬠(24). All these physical features impacted where the Indian and Egyptian city-states were set up and governed. Following that, most geographical features caused isolation. China and Egypt had a lot of isolation because of the mountain ranges and deserts that surrounded and bordered them. China had the ââ¬Å"â⬠¦high mountain ranges- the TienShan and the Himalayas-and brutal deserts blocked the easy movement of peopleâ⬠¦southeast, thick jungles divided China from Southeast Asiaâ⬠¦the north lay the forbidding desert, the Gobiâ⬠¦to the east, the fast Pacific Ocean. â⬠(59). Because China was so isolated by many physical features caused by the geographical movement they believe that they were the center of the Earth and the sole source of civilization. But Egypt was isolated from other civilizations by a vast stretch of desert and large bodies of water, making it a peninsula. This desert is the Sahara Desert, the largest desert in the world.The Sahara is difficult to get through making it harder to reach Egypt, thus making it isolated from migrating people and trade. Although the bodies of water created some isolation, it however helped with Egyptââ¬â¢s trade and excess to many ports. This shows that geographical knowledge is also important to understand history because if one did not know what type of physical features were available thou would now know what to expect. Lastly, geography allowed cultural diffusion between civilizations. Greece and China had a lot of cultural diffusion because both civilizations depended on trade to grow and prosper.The Greeks had ââ¬Å"â⬠¦hundreds of bays, the Greek coastline provided safe harbors for ships. â⬠(105). This shows that the Greek economic system highly depended on trading overseas; Greeks became skilled sailors, who carried cargoes of olive oil, wine, and marble around the Mediterranean area. Because the Greeks were traveling so much to other are as to trade they went back home with new ideas and different traditions, some making their lives easier. For example, ââ¬Å"Greeks expanded the Phoenician alphabet. The resulting Greek alphabet became the basis for all western alphabets. (105). All of the trading and traveling overseas made Greece become more populated and prosperous forcing man Greeks to leave their own overcrowded valleys and vineyards and when they left they brought the Greek culture and ideas with them. Now moving eastward toward China to the Silk Road to the West, which was very important link to China and the rest of the world. ââ¬Å"During the Han period, new foods such as grapes, figs, cucumbers, and walnuts flowed to China from western Asia. â⬠(95) Making this region grow even more culturally more than ever.Although China is very isolated, it still traded as much as Greece would have; the Silk Road eventually stretched for 4,000 miles linking China to the Fertile Crescent. ââ¬Å"China also traded t ons of silk westward to fill a growing demand for the prized fabricâ⬠(95) and in return China would return with furs from Central Asia, muslin from India, or glass from Rome. The Silk Road was not only an important trade route it was also had many controllers making it more likable; ââ¬Å"at the western end, trade was controlled by various people, including the Persians. â⬠(95).This makes geography even more important to understand history. In conclusion, the study of geography is very important to the understanding of history. People. Mountains. People. Culture. People. Water. Everything is connected. The development of city-states, suspended isolation, and cultural diffusion all has to do with ancient civilizations history and geography. It also has effect on todayââ¬â¢s environment. In the end it is important to know both subjects even though that knowledge may not be applied to lives in any way, shape, or form it is still something useful to know.

Biological molecules lab report Essays
Biological molecules lab report Essays Biological molecules lab report Paper Biological molecules lab report Paper This does not mean to just restate what was in your sample. Think about it. Analyze it. Does the result make sense, based on the label and on what is known about the food. Do the results make sense to you. If they do not, think about, and research, what might be going on. Do not judge, just report (i. E. The soda is bad because it is full of sugar is a judgmental statement). A series of tests were performed on various different products to determine whether any of them contain glucose, starch, protein, or lipids. The Benedicts test is used to determine whether a product contains glucose. From the products used only Peptidase, chicken broth, regular lime soda, and red bull tested positive for glucose molecules. When a test is positive it turns into a red-orange color. The results for most of these products make sense with the exception of the peptidase. At first glance, peptidase does not seem like it should be in this category. After doing research, it was found that peptidase is actually made with the amount of glucose and fructose recommended by the American Academy of Pediatrics. Next was the Iodine test for starch. When an Iodine test is positive, it turns black. After conducting this test, it was found that chicken broth was the only product in the list that contains starch. Later the Beirut test was performed to check for protein in products. After conducting the test it was established that rice milk and coconut water both contain protein. At first, this does not seem logical. After doing research it was discovered that rice milk and coconut water do indeed contain protein, although they are not significant amounts. Last, the Sudan IV test for lipids was performed. When a Sudan test is positive, the red dye will disperse and dissolve within the lipid.
