Analyzing The Structure, Synthesis, Function,...

Magnetotactic bacteria are a group of prokaryotes of varying morphologies. The morphologies include coccoid, helical, multicellular, rod-shaped, and vibriod (Bazylinski 1995). Magnetotactic bacteria were first discovered by Salvatore Bellini in 1963 (Jogler 2009). The commonality of all members of magnetotactic bacteria is that they passively orient and swim along the geomagnetic field by means of a method called magnetotaxis. The ability to swim along the geomagnetic field is made possible by an intracellular structure that all magnetotactic bacteria have, called the magnetosome ( ). Other commonalities that magnetotactic bacteria share is that they are all gram-negative bacteria, are motile by means of flagella, exhibit negative growth†¦show more content†¦Multiple morphologies of magnetosomes have been identified with electron microscopy. The forms include bullet-shaped, cubo-octahedral, elongated prismatic, and rectangular (Yan). Although there is some variation in the m orphology of magnetosomes, the morphology is consistent within a single magnetotactic species or strain (Bazylinski 1994). Magnetosomes are surrounded by a lipid bilayer membrane that is 3-4 nm thick (Bazylinksi 2004). MORE *Talk about size of magnetosome, how they line in a row, dipole moments Synthesis of Magnetosomes As stated before, iron sulphide magnetosomes are not well researched. Consequently, very little is known about the conditions needed to synthesize greigite crystals. It is speculated that iron sulphide mineralization occurs in the absence of oxygen, as these types of magnetosomes are found in anaerobic and sulphidic conditions (Bazylinski 1993). As magnetite is well-researched, multiple factors influence the formation of iron oxide magnetosomes have been identified. The most important factors are the presence of oxygen, and substrates in the form of nitrogen oxides (Bazylinski 2004). MORE Synthesis of the magnetosomes is performed as a multistep process. The steps include magnetosome vesicle formation, iron uptake by the bacteria, iron transport into the magnetosome vesicle, and controlled biomineralization of either magnetite or greigite into the vesicle (Bazylinski 2004). Although the steps are known,

Race Film The Great And Only Essay - 10250 Words

Chapter One Race Films as a Genre in American Cinema â€Å"Most people pronounced his last name ‘Mee-show,’ though some who knew him insist it was ‘Mi-shaw.’ The correct pronunciation of his name is only the beginning of the ambiguities and mysteries associated with Oscar Micheaux† Patrick Mulligan—Oscar Micheaux: The Great and Only: The Life of America s First Black Filmmaker From the very beginning of the early stages in American cinema, African Americans had a presence on the silver screen. The twentieth century created a new era of cinema that consisted of films produced for and targeted to an all-Black audience. â€Å"Race films† which existed in the United States for over thirty years (1913-1948), were films produced by African Americans that focused on Black themes and highlighted the talents of African American directors, producers, scriptwriters, and actors. However, according to African American film scholar Thomas Cripps, these early films were not truly Black because their function, more or less, were to enlighten and mollify White people’s curiosity concerning Black culture. The argument presented by Cripps creates an opportunity for speculation on how to categorize a well-known group of films about Black people that in most cases included the participation of White filmmakers. How do we define the term â€Å"race film†? Moreover, can these films be considered a â€Å"genre† or are they imitations of similar narratives produced by White filmmakers such as comedies,Show MoreRelatedThe African American Portrayal Of The Film Genre, Big Timers ( 1945 ) And Dirty Gertie From Harlem871 Words   |  4 PagesThe African American portrayal in white-American entertainment, especially in films has produced malicious and ignorant beliefs of the everyday Black person.

Analyse the Rise to Power of Joseph Stalin free essay sample

Joseph Stalin became the leader of the USSR after it’s first leader Vladimir Lenin died. Stalin’s rise to power was violent and ruthless, however the result was just what he wanted to achieve. In this essay I will analyse the rise to power of Joseph Stalin as well as look at the steps, which he took towards becoming a totalitarian leader of the USSR. Joseph Stalin was studying to be a priest but he was expelled for his revolutionary activity. Stalin has attracted Lenin’s attention because of this revolutionary activity and Lenin was helping Stalin to rise in party leadership. This can be considered Stalin’s first step towards becoming a dictator. This clearly shows that his way up in the party leadership began from being promoted by Lenin. After Lenin’s death, there were five main people struggling to achieve the position of a leader of USSR. We will write a custom essay sample on Analyse the Rise to Power of Joseph Stalin or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page These were: Trotsky, Bukharin, Kamenev, Zinoviev and Stalin. Stalin wanted to become the leader of USSR. His main rival was Leon Trotsky because he had the support of the Soviet people. Trotsky, Kamenev and Zinoviev joined together to oppose the continuation of the New Economic Policy (a new and more capitalized economic policy, which was supposed to revive the Soviet economy that was ruined after the Civil War. NEP allowed farmers to earn extra money). Their wishes appeared to go against Lenin’s. Trotsky had a policy called ‘Permanent Revolution’. He wanted to spread communism to the neighboring countries. Stalin had a different point of view – he believed that at first it was important to establish and strengthen communism in the USSR. Stalin was able to appoint his supporters on key positions in the communist party. He was able to do that mainly due to the fact that Trotsky was busy gaining the support of the people because he wanted to convince them about the benefit of ‘Permanent Revolution’ and also he believed that it is important to have the support of the nation. As a historian Norman Pereira said about Stalin putting his supporters around him: ‘He was an arch-bureaucrat who put together a coalition of party secretaries who had no truly revolutionary intent and were preoccupied by a concern for bureaucratic privilege. ’ Stalin sided with Bukharin. Trotsky, Kamenev and Zinoviev were announced as traitors to Lenin as they didn’t want the continuation of the NEP (New Economic Policy). They were expelled from the party. Later, Trotsky was killed by Stalin’s NKVD (secret police) in order to eliminate him as a competitor completely. The two of his very important rivals and his main rival were no longer an obstacle for Stalin. Bukharin has originally sided with Stalin to get rid of Trotsky, Zinoviev and Kamenev. After they were gone, he wanted to continue the NEP, as this is what Stalin told him they should do. In 1927 Stalin sent soldiers to arrest anybody who was making profit as a result of the NEP. Bukharin now accused Stalin of being a tyrant. Due to that, Bukharin was expelled from the party as Stalin had appointed his supporters on key positions in the party, making it possible for him to expel Bukharin. Stalin became an undisputed leader of the USSR. Conclusively, I believe that Stalin has used several methods to rise to power, most of them being manipulative such as assigning his supporters to key positions in the communist party and alliance with Bukharin in order to eliminate other rivals. In the end, he has successfully become a dictator of the Soviet Union who will later lead the country through its biggest challenge – the Second World War.

Manufacturing The Products In House Samples †MyAssignmenthelp.com

Question: Discuss about the Manufacturing The Products In House. Answer: The decision regarding whether a business needs to manufacture or purchase a product depends on both tangible and intangible factors, which might change with the passage of time. Manufacturing the products in-house might help in saving money and time. However, it is convenient as well to purchase from a vendor specialising in the particular item. Moreover, making a product from the initial stage could be a method of providing additional work for the valued staffs during the slowdown of the business. A make or buy decision is the act of selecting between making a product or purchasing the same from an external supplier. In make or buy decision, the most significant factors to be taken into account include portion of quantitative evaluation like the related production cost and whether the organisation has the capacity to manufacture at the needed levels. It is referred as the decision of outsourcing, as it contrasts the benefits and costs related to production of a particular product or service internally to the benefits and costs associated with hiring an external supplier for the questionable resources. In order to contrast the costs rightfully, each aspect about the acquisition and item storage needs to be taken into consideration. The primary factors to be considered in deciding whether to manufacture the canisters or buy the same from the outside supplier include the following: Quality: If Playdough Company could develop a product, which is better in contrast to purchasing from a vendor, it is necessary to make the canisters in-house. It is assumed that the organisation could charge a greater price in justifying labour and materials. However, if the organisation fails to specialise in canisters, a specialist vendor would be highly effective. Since Playdough Company is involved in making value-added canisters, it could provide greater quality by making raw materials from the beginning, as they would be fresh optimally. Quantity: The product volume that the organisation requires would affect the decision of whether to manufacture or purchase the same. For instance, if Playdough Company needs a box of canisters, it is impractical to fashion the same from the initial stage. However, sometimes a huge demand in the market could be a cause of not to make an in-house product. In case, the organisation uses 10,000 boxes for packaging products, it could be considered as cost-effective to contract to a third party firm foe making them to a custom size (Fullerton, Kennedy and Widener 2013). Convenience: When Playdough Company has been operating in high gear to meet the current demand, it would be highly feasible to make the products, instead of purchasing the same. However, if the vendor of the organisation that manufactures the product belongs to a cross-border nation and it could not dispatch the needed items on short notice, it is feasible to manufacture the product in-house. The convenience of purchasing or making products might change in relation to the overall sales volume that the organisation is presently transacting along with the amount of additional space and labour of the same. Marketing: In the words of Otley and Emmanuel (2013), making in-house products is a significant strategy of marketing. For instance, in case of clothing store making and selling its own dress line provides the customers with an added value and a strong brand. Similar is in the case of a restaurant making its own sauces and dressings, which provide unique flavours. In case of Playdough Company, making canisters could add additional features to the product. However, the discriminating and savvy customers often concentrate on whether the organisation has made or purchase the products it sells. Hence, Playdough Company could develop its own inventory for building an educated and loyal client base. Thus, based on the above discussion, it could be stated that the factors affecting the decision of Playdough Company to purchase canisters instead of producing them in-house comprise of lack of internal expertise, small requirements of volume, desire for varied sourcing and the fact that the item might be crucial to the strategy to the organisation. Excessive consideration might be provided, if the organisation obtains the opportunity to work with a firm providing outsourcing services successfully in the market to develop a long-term association. In a similar fashion, the influential dynamics towards manufacturing an item include the current capacity of production, effective quality control and proprietary technology needing protection. Finally, it is necessary for the firm to consider whether the supplier could seek for long-term arrangement, if necessary during high demand situations.
