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 – what he had felt and thought - in the short story ‘Now I Lay Me’ (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 GEF’s. Activation of GTP-proteins leads to activation of several protein kinases (known as ‘MAP-kinase’). MAP-kinase can bring about phophrylation and activation of nucleus transcription .B. Pertussis sticks to the cell with the help of â€Å"filamen tous hemagglutinin† (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 ‘complement receptor-3’ (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 worlds’ 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 â€Å"†¦one Indian name for â€Å"river†: lok-mata, or â€Å"mother of the people. † (World History Book, page 52). Now the Nile River Valley was very fertile, which made â€Å"†¦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 â€Å"Black Land† was the rich and irrigated area of the Nile Valley and â€Å"no more than 10 miles wide, lay the ‘Red Land,’ a sun-baked desert that s tretches across North Africa. † (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 â€Å"†¦high mountain ranges- the TienShan and the Himalayas-and brutal deserts blocked the easy movement of people†¦southeast, thick jungles divided China from Southeast Asia†¦the north lay the forbidding desert, the Gobi†¦to the east, the fast Pacific Ocean. † (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 Egypt’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 â€Å"†¦hundreds of bays, the Greek coastline provided safe harbors for ships. † (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, â€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. â€Å"During the Han period, new foods such as grapes, figs, cucumbers, and walnuts flowed to China from western Asia. † (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. â€Å"China also traded t ons of silk westward to fill a growing demand for the prized fabric† (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; â€Å"at the western end, trade was controlled by various people, including the Persians. † (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 today’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.

Anton Chekhov - Biography and Profile

Anton Chekhov - Biography and Profile Born in 1860, Anton Chekhov grew up in the Russian town of Taganrog. He spent much of his childhood quietly sitting in his fathers fledgling grocery store. He watched the customers and listened to the their gossip, their hopes, and their complaints. Early on, he learned to observe the everyday lives of humans. His ability to listen would become one of his most valuable skills as a storyteller. Chekhovs YouthHis father, Paul Chekhov, grew up in an impoverished family. Antons grandfather was actually a serf in Czarist Russia, but through hard work and thriftiness, he purchased his familys freedom. Young Antons father became a self-employed grocer, but the business never prospered and eventually fell apart. Monetary woes dominated Chekhovs childhood. As a result, financial conflicts are prominent in his plays and fiction. Despite economic hardship, Chekhov was a talented student. In 1879, he left Taganrog to attend medical school in Moscow. At this time, he felt the pressure of being the head of the household. His father was no longer earning a living. Chekhov needed a way to make money without abandoning school. Writing stories provided a solution. He began writing humorous stories for local newspapers and journals. At first the stories paid very little. However, Chekhov was a quick and prolific humorist. By the time he was in his forth year of medical school, he had caught the attention of several editors. By 1883, his stories were earning him not only money but notoriety. Chekhovs Literary PurposeAs a writer, Chekhov did not subscribe to a particular religion or political affiliation. He wanted to satirize not preach. At the time, artists and scholars debated the purpose of literature. Some felt that literature should offer life instructions. Others felt that art should simply exist to please. For the most part, Chekhov agreed with the latter view. The artist must be, not the judge of his characters and of what they say, but merely a dispassionate observer. Anton Chekhov Chekhov the PlaywrightBecause of his fondness for dialogue, Chekhov felt drawn to the theatre. His early plays such as Ivanov and The Wood Demon artistically dissatisfied him. In 1895 he began working on a rather original theatrical project: The Seagull. It was a play that defied many of the traditional elements of common stage productions. It lacked plot and it focused on many interesting yet emotionally static characters. In 1896 The Seagull received a disastrous response on opening night. The audience actually booed during the first act. Fortunately, innovative directors Konstantin Stanislavski and Vladimir Nemirovich-Danechenko believed in Chekhovs work. Their new approach to drama invigorated audiences. The Moscow Art Theatre restaged The Seagull and created a triumphant crowd-pleaser. Soon after, the Moscow Art Theatre, led by Stanislavski and Nemirovich-Danechenko, produced the rest of Chekhovs masterpieces: Uncle Vanya (1899) The Three Sisters (1900) The Cherry Orchard (1904) Chekhovs Love LifeThe Russian storyteller played with themes of romance and marriage, but throughout most of his life he did not take love seriously. He had occasional affairs, but he did not fall in love until he met Olga Knipper, an up-and-coming Russian actress. They were very discreetly married in 1901. Olga not only starred in Chekhovs plays, she also deeply understood them. More than anyone in Chekhovs circle, she interpreted the subtle meanings within the plays. For example, Stanislavski thought The Cherry Orchard was a tragedy of Russian life. Olga instead knew that Chekhov intended it to be a gay comedy, one that almost touched upon farce. Olga and Chekhov were kindred spirits, though they did not spend much time together. Their letters indicate that they were very affectionate to one another. Sadly, their marriage would not last very long, due to Chekhovs failing health. Chekhovs Final DaysAt the age of 24, Chekhov began showing signs of tuberculosis. He tried to ignore this condition; however by his early 30s his health had deterorated beyond denial. When The Cherry Orchard opened in 1904, tuberculosis had ravaged his lungs. His body was visibly weakened. Most of his friends and family knew the end was near. Opening night of The Cherry Orchard became a tribute filled with speeches and heartfelt thanks. It was their was of saying goodbye to Russias greatest playwright. On July 14th, 1904, Chekhov stayed up late working on yet another short story. After going to bed, he suddenly awoke and summoned a doctor. The physician could do nothing for him but offer a glass of champagne. Reportedly, his final words were, Its a long time since I drank champagne. Then, after drinking the beverage, he died Chekhovs LegacyDuring and after his lifetime, Anton Chekhov was adored throughout Russia. Aside from his beloved stories and plays, he is also remembered as a humanitarian and a philanthropist. While living in the country, he often attended to the medical needs of the local peasants. Also, he was renowned for sponsoring local writers and medical students. His literary work has been embraced throughout the world. While many playwrights create intense, life-or-death scenarios, Chekhovs plays offer everyday conversations. Readers cherish his extraordinary insight into the lives of the ordinary.

Role of securitization and structured finance products in the recent Essay

Role of securitization and structured finance products in the recent banking and financial crisis - Essay Example The paper describes the role of securitization and structured finance products in the recent banking and financial crisis. Financial institutions cater to the needs of different types of customers by providing relevant financial services. Financial institutions worldwide have been affected by the adverse market environment created by the US sub prime fiasco. Trouble began when the financial companies started relying too much on the innovation in the blind faith that it will yield returns. As it is common knowledge that banking industry has suffered the most due to the current meltdown, the symptoms of the malaise started emerging in the US mortgage business first. The cracks appeared in the banking system. Housing prices, according to Financial World started falling in the year 2005. Initial symptom appeared in the market for sub prime residential mortgage-supported securities as investment demand shrank in 2006. In February 2007, auctions to finalise rates on ARS instruments failed because of decreasing investor demand. Cracks in financial market became wide open in June 2007 with the failure to meet the lenders’ call on Collateralised Debt Obligations by two Bear Stearns hedge funds for subprime loans. ... After a reset period of two years, interest rates went higher as Fed interest rates also touched a high level, on which sub prime mortgage interests were based. Housing prices started declining sharply after the boom period. A wave of repossessions was behind this trend. Banks started taking precautionary measures, cutting back on credit to cover risks to their investments. Being forced to dry up the whole sale bond market and their balance sheets from the adverse affects, banks started shrinking their portfolio. The Pension Funds suffered the severe losses being the prime purchasers of sub prime mortgage bonds. As the banks have hidden their holdings of sub prime mortgages in off-balance sheet instruments such as â€Å"structured investment vehicles† or SIV’s, they were reluctant to bear the losses. 2. What caused the crisis? The US financial system was under observation, as reported for planning its restructuring and strengthening control but still there is no clarity on what regulatory policy change has been enforced even till June 2009. Limits on mixing of the investment with commercial banking within the financial market were put off by getting away with the Glass-Steagall Act. Investment banks were not regulated for levering up their conditions. Financial innovations promoted easy availability of credit. Loan s against mortgages were â€Å"securitised† and forwarded by associates of Lehman Brothers and other financial companies. The outcome was unhindered consumer spending and reducing household savings. (Schneider & Kirchgassner, 2009). In the US, internal policies and globalisation was responsible for the financial crisis, which was fuelled by innovative products like complex derivative securities,
