Biology Virus Essay

Biology Virus Essay A virus is a microorganism that cannot reproduce without a host. As a result of this, there has been a lot of controversy on whether or not a virus is a living or non-living organism. The dictionary. com definition for life is, â€Å"the condition that distinguishes organisms from inorganic objects and dead organisms, being manifested by growth through metabolism, reproduction, and the power of adaptation to environment through changes originating internally. Viruses have characteristics of both living and non-living organisms, for example, a living characteristic includes reproduction. A non-living characteristic of a virus is that they cannot have both DNA and RNA. The living characteristics of viruses state that viruses can reproduce, but viruses can only reproduce with the help of a host. As a result of viruses not being able to replicate on their own, viruses are not living organisms. Viruses are small infectious particles that have nucleic acid. They can come in many different shapes and sizes. Although viruses vary in shape the common virus has four main parts, the head, DNA or RNA, tail sheath, and tail fiber. The head of a virus is a protein shell that protects the DNA inside it also known as the genome. In comparison, viruses and living organisms both are made up of smaller units that form up to make something larger. The physical appearance of a virus and living organisms are different and what a virus is made up of is different in comparison to a living organism. Viruses are made up of proteins and nucleic acid. The protein comes together to form an encasing shell for the nucleic acid. The protein shell is called a capsid. The nucleic acid inside a capsid can either be DNA or RNA, but never both. Viruses can be classified depending on the features they have, for example the various shapes of a capsid can determine the type of virus. A capsid can be a simple or complex structure. The most complex capsid is found in bacteria called bacteriophages. A virus can also have a viral envelope which contains protein and lipids. Based on shape and structure viruses can infect bacteria, animals and plants. The way in which viruses can infect theses organisms is different. The viruses that infect bacteria are the most common. The life cycle of viruses that infect bacteria are put into two categories known as the lysogenic and lytic cycles. In the lytic cycle, the virus injects its DNA or RNA into the bacteria and makes the bacteria create all the different components that form an entire virus. These parts come together to create individual viruses and as a result of this mass production of individual viruses, the cell bursts. Viruses that go through the lytic cycle are called virulent phages. Phages that go through the lysogenic cycle are known as temperate phages. In the lysogenic cycle the virus injects its DNA or RNA into the host in the same way as the lytic cycle does except the injected DNA or RNA sits and stays inside the host. As a result the virus doesn’t create more individual viruses and the host’s cell doesn’t burst. Although the nucleic acid sits and stays inside the genome, a reaction could occur and the virus could go from the lysogenic to the lytic cycle. In conclusion, viruses have characteristics of both living and non-living organisms. Like non-living organisms, viruses can’t have both DNA and RNA. They can reproduce like living organisms but that is with the help of a host. Without the help of a host viruses can’t perform the characteristics of a living organism. Due to the lack of living characteristics, this shows that viruses are not living organisms.

Marketing and Nike Essay

We can evaluate Nike’s core marketing strategy as related them to the relevant marketing theories. First of them is distribution theory. Nike distributes its products on different level basis. The high quality products are given to a certain distributers while the low price to be sold at highly discounted price at the retail stores such as Wal-Mart. Nike has also become the leader in the e-commerce by being the first to the market whit its e-commerce website. This program represents the first time a company has offered mass footwear through the internet and provides competitive advantages to Nike. One of the other theories is advertising and promotion. Nike makes contracts with some celebrity athletes which can take attention to their products such as Michael Jordan, Tiger Woods, Maria Sharapova, Ronaldo. This has created a relatively high level of Nike’s awareness. Nike also employed a large amounts of advertisements. Their aggressive advertising campaigns, celebrity endorsements and quality products all enhance their brand and image. The other theory is price. The price is not effective on their strategy because Nike’s target market is based on the consumers who care more about the utility and quality of the product . This strategy focuses on the consumers who like Nike and pushes the products value to a higher level. Once the consumer develop the product intimacy, they come to associate their person with the products and will pay whatever price quoted on the products. Nike use vertical integration price strategy and they also engaged in various channel level operations both to control costs and influence the price function. And when we look at the market segmentation theory, we see that most of the consumer of Nike’s products is mainly athletic. Their segmentation market typically targets athletes, both women and men, from the age 15 to 35. Nike focuses on creating premium consumer experiences on product innovation, brand leadership and elevated retail presence. But Nike focuses on athlete more than any group of individuals. This strategy is especially successful because of its ability to reach a large number of athletes. Although Nike’s core marketing strategy had brings lot of positive directions to the company, but it will bring negative directions to Nike too. The mainly negative theory is the cost theory. Nike had incurred high costs in producing and promoting its products. The costs are increasing among handling inventory, designing, advertising and production. The inflation had also rised the costs. So Nike has increased the products prices and reduces its marketing budget. Nike had also employed child labor in Cambodia to reduce its production and labor costs. This affected brand image negatively and many people stop buying products from Nike. Furthermore, Nike has been using child labor in the production of its soccer balls in Pakistan. One of the Nike’s core marketing strategies is depend on a group of athletes to promote its products. Nike prefers to have high profile athletes as its endorsers, like Runner Steve Prefontaine, Michael Jordan and LeBron James. The action and attitude of Nike’s chosen spokespersons could bring the impacts on its promotional strategies. For instance, it will attract the athlete’s idolater to purchase the products if Nike using a popular athlete as endorser. On the other hand, if the athlete were caught in drug addicted or any immoral attitude, it will affect the customers not to buy Nike’s products, thus will affect Nike’s sales, revenue and profit. There is intense competition faced by Nike. Their competitors are Adidas, Reebok, Puma, and so forth, whilst competition is tighter with the coming of Adidas. More, the product line is slightly different between Nike and Adidas. Nike faces many risks when they use their core marketing strategies to achieve their goals and these risks can come from both internally and externally environment. The risks will have a negative influence about Nike’s future development. Nike needs to stay on the top of changes in consumer taste and preferences as evidenced by changes in fashion. So Nike face the risk that fashion trends may change so fast that Nike fails to follow. If Nike cannot follow the fitness trends in the market they will face risks of losing market shares. To compete with this risks and problems, Nike should position it as a trendsetter and not a trend follower and be responsible to their customers. The global trends are to be fashion and personality. So Nike change its marketing strategies and products design to become more fashion and focus on the youth consumers. It brings risks to Nike because in the traditional mind of customers, they consider Nike only sell the athletic products. The fashion or the changing style products is unimaginative for customers to purchase. Not all the customers can follow the changing of Nike. Therefore, Nike should analyse the market and customers’ preference as well as customers’ buying behavior from time to time. One of Major Nike’s marketing strategies is to expand to overseas and become the leader in the world. It also will bring risks to Nike when they expand their business globally. Currency exchange rate fluctuations can disrupt the business of the independent manufacturers that produce Nike products by making their purchase of raw materials more expensive and more difficult to finance. Besides that, the global economic recession influence the overall business operation in the outsourcing countries. 2) If you were Adidas, how would you compete with Nike? One difficulty most likely to be faced by Adidas is in its marketing, compared to its competitor Nike, Nike spends more money on advertising and promoting their products reputation. Adidas will have a hard time trying to compete with Nike in terms of advertising and promotion, considering Nike’s utilization of low labor cost of production, Nike can afford to spend so much money in creating awareness for their products and gaining consumers loyalty by utilizing celebrities. If I were Adidas I would invest more money on advertising and create innovative means of advertising their product, having consumers in mind and following the trends of technologies, for example, Adidas can collaborate with IT companies such as Samsung to create innovative means of advertising their products. Also a merger could be good for the Adidas, if the right strategy has chosen. For example; Adidas and Reebok joining up together as a merger would be a good deal for leading over Nike but the two companies have a bad reputation due to financial problems which almost led them to bankruptcy and since they are to work together.

Sandstone Reservoirs Research Paper Example | Topics and Well Written Essays - 1250 words

Sandstone Reservoirs - Research Paper Example Examples of sandstone reservoirs are found in Western Canada Sedimentary Basin, coastal basins of Equatorial Africa, United States’ Gulf Coast, Rocky Mountains and Southern North Sea (Stoneley 39). 2. Carbonate Rock Reservoirs Carbonate reservoirs comprise of geologic formation that are naturally fractured which are characterized by heterogeneous permeability and porosity distributions. These are the predominant types of reservoirs all over the world accounting for about 50% of all reservoirs. The distinctive aspect of carbonate reservoirs is their intrabasinal origin. Their mode of formation was primarily dependent on organic activities. They were formed through biochemical processes in special environments. Organisms involved in their formation also contributed in determination of their qualities. Carbonate reservoirs are highly susceptible to processes of modification as a result of post-depositional mechanisms. The variations observed among various carbonate reservoirs res ult from processes such as lithification and compaction (Ahr 50). A notable feature of these reservoirs is their high sensitivity to environmental changes. Changes in temperatures affect biogenic activities thus affecting sediment production. This aspect is what makes carbonate reservoir development depth dependent. Favorable conditions enhance organic productivity while in unfavorable conditions productivity ceases. Carbonate reservoirs are considered autochthonous since they develop close to their final depositional sites. Water energy and basin configuration influences deposition which leads to formation of carbonate reservoirs. Examples of carbonate reservoirs are found in Big Horn Basin in Wyoming and south Caspian basin which encompasses... They develop better vugs and fractures that are relatively important for flow and storage of fluids. Carbonate reservoirs are also harder and tighter than sandstone reservoirs (Renpu 9). Primary porosity of sandstone reservoirs is exclusively interparticle while that of carbonate reservoirs can either be intraparticle, interparticle, intercrystalline, vuggy, fenestral or cavernous. Porosity-permeability relationships of sandstones are relatively consistent and dependent on particle texture while that of carbonate reservoirs are highly varied and independent of particle size (Ahr 53). Shale reservoirs differ from sandstone reservoirs in that shale reservoirs can contain organic mudstones which are not present in sandstone reservoirs. They can also have open fractures which are not common in sandstone reservoirs. Conglomerate reservoirs differ from sandstone reservoirs in that conglomerate reservoirs exhibit an extra-high heterogeneity as a result of a complex pore structure. They also display rapid changes in permeability and porosity between their layers which is not the case with sandstone reservoirs (Zou 298). Advantages of Sandstone Reservoirs Porosity of sandstone reservoirs is uniform over time since it does not diminish with increasing saturation of the reservoir. Chemical processes do not affect the permeability and porosity of sandstone reservoirs. Effects and of micro and macro organisms do not impede fluid transfer through sandstone reservoirs as can be the case with carbonate reservoirs (Renpu 11).

Legal Systems Assignment Example | Topics and Well Written Essays - 1750 words

Legal Systems - Assignment Example On March 22, 2005 six men were acquitted from a fraud case costing 60 million. Considered to be one of Britain's longest and costliest fraud trials, it just collapsed after twenty-one months of court proceedings at London's Old Bailey.2 The jury's inability to come up with a fair verdict was pointed out to be the reason for such failure. There had been disruptions and problems with the selected jury and further allegations regarding an unfair trial rose. The verdict cause the public to not to remain in silence that caused unrest among the government. This situation led to the Attorney general to impose on the Criminal Act of 2003 regarding fraud trials that put the juries out of the scene. 4 There had been protests even when it was proposed by the Attorney General Lord Lord Goldsmith. However, the pressure to remove juries from the most difficult cases dates back to the Roskill committee on fraud trials, which recommended trial by a judge with expert lay assessors in 1986.5 The implementation of Part 7 of the Criminal Justice Act of 2003 seemed to be the most appropriate practice in complex fraud trials as what happened in the Jubilee line trial. The Government is no longer willing to lose millions of money spent on a single trial thus a trial without a jury is an alternative. The parliament's approval on the said proposition was justifiable through certain aspects that may seem unreasonable for some conservative groups who are not able to see the real deal behind the fraud trials with a judge-only trial. Further explanations regarding this provision were explained in the Explanatory Memorandum to the Criminal Justice Act 2003 (Commencement No. 12 and Transitory Provisions) Order 005. The following are some of the details regarding its implementation. The Government considers that there are certain fraud cases where the length or complexity of the trial is likely to be so burdensome to the jury that it is in the interests of justice that the trial be conducted without a jury by a judge sitting alone. Provisions in Part 7 of the Criminal Justice Act 2003 give effect to this policy and provide for prosecution applications for certain fraud cases to be conducted without a jury. The requirement that the provisions apply only to cases where a notice has been given under section 51B of the Crime and Disorder Act 1998 limits them to cases of serious or complex fraud.6 The provisions operate only where an application is made by the prosecution, the judge is satisfied that the length or complexity of the trial is likely to make it so burdensome upon the jury that the interests of justice require a non jury trial, and the Lord Chief Justice or a judge nominated by him gives his approval.7 It is the Minister's view that the provisions in Part 7 of the Criminal Justice Act 2003 for non jury trials for certain fraud cases are compatible with Convention Rights, as Article 6 of the Convention (right to a fair trial) does not include a right to trial by jury. The Joint Committee on Human Rights commented (Second Report: Criminal Justice Bill, paragraph 5) -

Female gemital circumcision or mutillation Research Paper

Female gemital circumcision or mutillation - Research Paper Example The women are still subjugated and made docile in order to be the minions of men forever. This smacks of the wider agenda on the part of men in those countries to keep silent on the practice so that their supremacy is not threatened. Female genital mutilation is (FGM) a procedure forcibly practiced on girls for non-medical reasons mainly prompted by religious beliefs. This age-old practice has been under severe criticisms for the past more than two decades. It is a deliberate assault on the female body that is physically and psychologically damaging. In the era of human rights, the practice is highly barbaric and condemnable. This paper aims to make a systematic review of literature on the subject ranging from age-old practice, human rights violations to health ramifications. The review should rest with the latest status of the practice and conclude whether it has been completely eradicated, on the decline, on the increase instead or in the same old status and to ascertain what health authorities and human rights enforcement have achieved so far in containing the practice. Various practices include Sunna, Modified Sunna, Clitoridectomy/excision and the most extreme form of infibulations. In Sunna which means tradition in Arabic, prepuce of the clitoris is prickled, slit or removed In Modified Sunna, clitoris is either partially or totally excised. In Clitoridectomy or excision, clitoris is partly or entirely removed as also all parts or part of the labia minora. The extensive scar tissue as a result occludes vaginal opening. In the most extreme form called infibulation or pharoanic circumcision, clitoris is removed and labia minora is excised along with its inner layers (Lightfoot-Klein, 1989). The last of these procedures is followed by stitching of the raw edges with cat gut or even thorns to make the edges adhere together so as to form a scar issue as a bridge to cover the vaginal opening. And some stuff such as silver of wood

Bizland ,inc - Case Study Example The company is evolving as the firm has added other products to its offering including marketing advice to small businesses, payroll and telephone services. II. Had they compiled an exhaustive list of criteria for their â€Å"must haves†? Had some important qualities been omitted? Were all of the items really necessary? If he and John did make changes, how would the four candidates measure up to the revised list? The firm formulated an exhaustive list of thing they were looking for in the CEO they seek to run the firm. Upon further review of their list I believe Ravi and his management team included a lot of important items needed to perform the job well. Despite their efforts there were some critical things that were left out. First the company did not include having excellent interpersonal and communication skills as part of the list. A CEO is the highest position in a company and this person must interact with a variety of people including employees, shareholders, board of directors, suppliers, and governmental agents. Another flaw in the list is that it did not include the requirement of being an expert negotiator. The CEO during a fiscal year faces numerous business opportunities in various facets of his job in which negotiation skills are vital to the success of the missions. III. Did the four candidates offer any real possibilities? Should they invite any of them for an interview with the entire Board of Directors? Or, even though it would further elongate the process, should Ravi and John begin considering other candidates not previously screened or interviewed? I think that the four candidates have real possibilities. All candidates hold MBA degrees and have over 10 years experience working in the business industry in various positions of importance. I do not think that it is required for the board to invite any more candidates because they already have some excellent
