The Oil Politics Essay Example for Free

The Oil Politics Essay The controversy over oil has been raging for quite a while. It has played into the international politics and the politics of terrorism. The Middle East is the most volatile area of the world at present. Israel is viewed as a satellite of the United States located in the Arab world to represent the superpowers interests in the region. Incidentally the Middle East is a region endowed with oil, a precious commodity sought after by every government. The main occupation and foreign exchange earner for these countries is therefore oil and petroleum products with which they use as a bargaining chip in the global arena. The current fluctuation in the price of petroleum around the world is a cause of worry. Some analysts are leveling blame on the oil producing countries claiming they have deliberately raised the oil prices. On their side, the countries have refuted the allegations instead blaming the rise to private entrepreneurs who hoard the commodity with the hope that prices would increase even further. Apart from the Middle East, North Africa has got also oil deposits. Coincidentally the region is also dominated by Arabs, who have formed grouping the organization of petroleum exporting countries OPEC. As importers complain of the rising oil prices, oil exporters celebrate the economic boom as a result of the rise in prices. Their gross domestic product increases and the general standards of living appreciate. As usual with the developed world to get their hands into any opportunity presenting itself, the oil industry is attracting foreign companies into Africa to help in the exploration of oil. New exploration sites are discovered in the vast continent of Africa, especially in the north. The bedeviled state of Mauritania is so far the latest country in Africa to join the league of oil exporters after explorations proved positive results. Since Exploration costs are damn expensive but this is not a hindrance to the exercise Africa is witnessing the largest investment in the continent ever, in the oil exploration field. Since the year 1990 more than US $20 billion has been spend on explorations around the continent and a further $50 billion is expected to have been spent by the end of the decade. Dominating the oil industry are three international companies, shell, Total and Chevron. Shell is a British Dutch consortium which invested 15% of its global exploration and production budget in the continent of Africa. France-based Total and America-based Chevron has invested 30% and 35% respectively in the industry in Africa. The American oil company has planned for United States$20 billion to be invested in Africa for a five year period. The Gulf of Guinea is the most appropriate part of Africa at the moment attracting the different exploration companies. It is an area with deep waters. This area found in the Western Coast of Africa just at the â€Å"armpit† is suspected to be having large deposits of the precious commodity. Some oil has already been discovered within the coverage area of the Gulf but more is still to be discovered as exploration progresses. Other sub-Saharan countries endowed with oil albeit smaller in quantities are southern Sudan and Southern Chad both under semi desert conditions. They have been producing oil and exporting in small quantities. The explorations are however taking place to find out if more can be tapped. The East Africa margin covering Kenya, Somalia and Tanzania are among targets of explorers for oil. The United States is warming up to reap from the harvest of oil and petroleum products from Africa. The country has been watching Africa from a distant making its calculations on how to have the continents oil. Discoveries in Africa increased making headlines in the last decade. The United States predicted an increase of its oil sourced from Africa by 10% from 16% to 25% by the 2015 the year when the United Nations’ millennium Development Goals are expected to have been achieved. In a report released in December of 2000 the United States National Intelligence Council predicted sub-Saharan Africa’s raise to prominence in the global energy markets. The council is a consultant for the central Intelligence Agency. If the predications come true, then the continent would be ahead of Saudi Arabia in terms of oil export to the United States. In close relation to this, the United States Vice President Dick Cheney formed a taskforce to compile a strategic report on oil. The report finalized by stating that West Africa will soon be among the fastest growing sources in the world in production of oil and gas for the United States (Basedau) As stated earlier, the United States receives around 16% of its oil from Africa a figure is expected to increase to 25% in 2015. at the current consumption rate the United States feels there is due need to increase oil energy inputs. This, the National Security strategy notes will be achieved by the United States strengthening its ties with the continent. In an effort for the United States achieving its dream it plans to invest in democracy crusades to strengthen the political systems in prospective source countries of oil. This is time as some of the target areas are marred by violence a situation that may make it difficult for exploration and transportation of oil. Examples in this case are Nigeria, a country rocked by a rebellion in the Niger Delta where oil is mined. The rebellion is led by people complaining of unfairness in the way resources are distributed. Chad is also facing the same problem with so many attempted coups, necessitating intervention by France to bring order and due process. Southern Sudan is equally bedeviled by the political instability problems. Of late, the Southern Sudanese leader Omar Hassan El Bashir has been recommended for arrest by the international criminal court prosecutor Moreno Ocampo for committing acts of genocide among other crimes against humanity. The fact that oil is in Southern Sudan a section that is demanding its independence from the mainland is a sign of worse times to come. This explains why the United States is busy pushing for a democratic regime in the region. On the 17th of May 2001 President Bush remarked on the importance of diversifying the source of energy used. He mentioned that overdependence on one source may result into a rude shock subjecting the United States to blackmail, supply interruptions and price shocks. The alternative available then remains to search for other sources west cost of Africa being in the list. Other areas are Latin America and the Caspian Sea basin (Klare, 2004). In Africa therefore, United States is planning for Nigeria, Angola and the states within the Gulf of Guinea. However the greatest hindrance for the United States would be as mentioned earlier, the political and ethnic tensions in the oil producing countries. The Delta region in Nigeria had the United States and other explores sent packing in 2003 due to the ethnic animosities and demands for more community project funding. The site produces much of onshore oil in Nigeria. The demands of these groups brought about massive vandalism of oil exploration sites causing a downsizing of Nigeria’s oil production instead of increasing. In its commitment to tap oil from Africa, the United States has therefore opted to give military assistance to friendly regimes to help them fight the menace of the cartels and armed groups blackmailing the government. Nigeria and Angola received United States assistance totaling to three hundred million American dollars from 2002 to 2004. The Excess Defense Articles program of the Pentagon also advanced eligibility to the two countries to receive surplus arms for the same reason. The United States has also been considering establishing naval bases especially in Nigeria and the Sao, Tome and Principe Islands. Currently the United States is supplied with oil from various countries with the highest supplier being Canada. Mexico and Saudi Arabia follow in the list in that order with Venezuela and the African country of Nigeria closing the top five list. Five to eight percent of 20 million barrels total United States demand per day is what each of these countries supply to the United States. An analysis of the 2005 oil supply to the United States puts Latin America highest at 34% of the total imports to the United States. The Middle East comes second supplying 24% while Africa supplied 19%. Canada stood at 16% and lastly Europe and Asia exported seven percent to the United States (Kern 2006). Africa’s oil is advantageous for its lack of sulphur thus making it preferable for stringent refined product requirements. It gives it a growing share in the market for refining centers in the United States. It is estimated that the Economic Community of West African States, ECOWAS, holds 3% of the total oil reserves globally. This is to the environs of 40 billion barrels, in the West African region alone (Kern 2006). The figures provided are conservative as the total estimates proven or otherwise may be more by four percent- that is 7%. West Africa countries the Bush Administration is targeting include- and the order remains arbitrary- Equatorial Guinea, Angola, Chad, Nigeria, Gabon and Congo. The fifth largest supplier of oil to the United States, Nigeria is the largest producer in Africa with a daily pumping of 2 million barrels. The figures also represent the quantity produced per day by Iraq before it was unilaterally invaded by the United States in March 2003. Being a member of the international cartel- the Organization of Petroleum Exporting Countries- Nigeria has to go by the policies and standards set by this grouping. They include limiting production to a certain level subject to the world market conditions. Due to a weak political system, Nigeria, with a population in excess of 130 million people is wallowing in the miasma of corruption and bad governance. Its annual per capita income reduced substantially from US $1000 to a mere $390 in 2006 with most of the proceeds from oil finding its way into individual’s pockets. The continent’s most populous nation earned more than US $300 in 25 years to 2006 but the revenue was shared among the bourgeoisie and the political elite. Only 1% of the population benefit effectively from 80% of the oil proceeds according to the World Bank (Kern 2006). In its recommendation, a 2005 report by the Center for Strategic and International Studies pointed out that America should prioritize explicitly the security and governance issue in the Gulf of Guinea in its foreign policy towards the continent. Titled â€Å"A Strategic US Approach to Governance and Security in the Gulf of Guinea† the report called for a promulgation of a robust and comprehensive policy for the West African region (Kerk 2006). As a matter of strategy the United States is considering softer military interventions in the continent. Through the Pentagon’s Trans-Saharan Counter-Terrorism Initiative, the United States provides military training to some nine African countries on ways of dealing with terrorism and on how to effect regional security. The US is further planning on establishing military bases in some African countries bordering the ocean for strategic reasons. Nigeria The damning story is the bloodshed and the hostage taking in Nigeria in Ogoniland. Hostage taking of foreigners is a way of life with the perpetrators demanding for resource control and access to oil money. The continent in general is a hotspot for oil, as east Africa is just about becoming the next oil boom for the continent, after the successful explorations in the west. In the East however, China would be the beneficiary due to proximity, the reason why it has its explorers in Kenya and Sudan. Nigeria is a strategic partner for the west. As the anchor for British and American foreign policies in Africa, the country has developed warm relations with the west. It is the most populous country in Africa with one out of every six Africans being a Nigerian (Ghazrinian 2007). The country has a large experienced army participating in peace-keeping missions around the world. The oil in Africa has not been used to its optimum potential. It is a bad news in some countries bringing on to the continent proxy wars of the west. China for instance gets 30% of its oil from Africa (Ghazvinian 2007). Of this 10% is from the Sudan where the Asian country has been accused of supplying ammunitions to the Sudanese Government, the ammunitions which are used to terrorize the people of Darfur in southern Sudan. The positive side of the Chinese is however, the human resource base they help build in Africa. They have participated in the development of infrastructure in Africa, as is the Angolan case where they jetted in for construction of railway line and tarmac roads with minimal conditions. Getting to the central African country of Chad, a country marred by violence and political instability. The country is in the Sahel region, twice the size of France with a 400 km-long paved road. It is among the poorest countries on earth, with the national airline having only one airplane. Ironically, the country lacks any gas station yet it produces the commodity. Its people are languishing in hell yet the country exports crude oil through Cameroon to Europe and America. The oil is traded through ExxonMobil Company. Worth mentioning also is the fact that some of these oil producing countries have the largest gaps between the poor and rich. In fact they are gulfs, not even gaps. The rich continue flourishing out of oil proceeds with the lower cadre of society languishing in abject poverty, malnutrition, diseases and low education, and living on less than a US$ a day! This then encourages prostitution as the effluent individual use the poor fellows as sex objects thus contributing to the spread of HIV/AIDS among other infections venereal diseases (Ghazvinian 2007). The oil factor is a cause of anarchy in most African countries. Democratic reforms are poised to increase with the decrease of oil revenues, as taxes would take up the position currently received for oil revenue. The regime has been neglecting the tax-paying middle class, concentrating instead on oil revenue thus neglecting social reforms. The case in Gabon is a pretty example. It is only when world oil prices fell and prospects for a decline in Gabonese oil realized that the Omar Bongo regime considered the economic reforms by the Breton Woods institutions aimed at democratization. The opposition gained a voice in governmental affairs as was a rise in civil society groups. He had to limit state allocations in 1986 after facing a rear break in the oil industry (Basedau). The presence of petrol-dollars retards people’s thinking on alternative income. Banana project, for instance, has been neglected yet it can earn handsomely to the nation and entrepreneurs in particular. Now they have left unpicked bananas as they import goodies from abroad. Sao Tome and Principe is yet another tiny African Island rocked in political instability but rich in oil resources yet to be exploited. It is facing a dilemma over how to share billions of barrels of oil reserves, offshore its territory. Anticipated are hostilities from its neighbors including the popular Nigeria. As tiny as it is, the country is so different from Africa: from its politics, society and culture. It is more European with little if any traces of African lifestyle (Ghazvinian 2007). In a 2003 speech in Washington USA, Sao, Tome and Principe President Fradique de Menez reiterated his hope and commitment that his Island would not drown into civil war, ethnic hatred and economic regression, because of oil. Oil is instead supposed to bring more development and economic satisfaction to the population (Ghazvinian). The country is however miserably poor with only high school but without any university. Half of the capital city is occupied by government officer. The national budget sums to a meager $50 million financed majorly from agriculture and fishing. Agricultural produce are coffee and cacao, putting the island in the list of the major recipients of direct aid relative to GDP as 35million is received annually in the form of international development aid. The country is not strange to armed coups. It is among the African countries who political cultures are informed by armed coups. Between 1991 and 2007, the island experienced fourteen changes of guard, with more uncertainties expected in case oil would be discovered. Nigeria is on record as having help crush an armed rebellion in Sao Tome in 2003,a clean indication of its involvement in the tiny African state.

Design Methodology Essay Example for Free

Design Methodology Essay A design methodology is series of phases that guide a project lifecycle. Generally speaking there are an uncountable number of design methodologies, but the two most utilised are the predictive and the adaptive approach. The predicative approach assumes that a project can be planned in advance and the adaptive approach assumes the opposite. These design methodologies are also referred to as traditional or waterfall approach and spiral or iterative approach respectively. The phases involved generally fall into the categories of planning, analysis, design, implementation and support. Whether implementing the predictive or adaptive approach, each phase is an important step in the design methodology but can differ depending on the approach taken. Additional, depending on the design methodology implemented, the phases may not exist as separate entities and can be combined, split up or even removed all together. During the planning phase the problem and scope are defined, a work breakdown structure and schedule is developed, a feasibility study is undertaken, team members are assigned and official approval is sought for commencement. The analysis phase involves gathering information relevant to the scope of the problem, constructing models or prototypes to assist information gathering, defining the goals or requirements and assessing and prioritising those goals or requirements. Information gathering techniques involve interviews, observation, reviewing industry standards, questionnaires, joint application design (JAD) sessions and general research. The design phase includes designing and integrating the system controls, designing the system and designing the system interfaces. The implementation phase involves constructing the system, verifying and testing the system, data conversion, training users, documenting the system and installation of the system. Finally, the support phase encompasses maintenance of the system, improving the systems and providing continual support for users of the system. The traditional or waterfall approach follows a sequential set of phases that need to be complete in order, one after the other. In most cases the waterfall approach does not contain overlapping phases and each phase must be completed before beginning the next phase. On the other hand, the adaptive approach involves repeating phases and/or overlapping phases. Usually the phases are repeated in a looping or spiral fashion but can also follow the more traditional linear pattern with overlap or loopbacks to only a few of the phases. Design methodologies encompass not only how the project lifecycle is planned out but also the models, tools and techniques used to assist the project lifecycle. Models can include anything from diagrams and charts to real world representations and abstract representations. Tools range from simple programs to produce models to complex Computer Aided Software Engineering (CASE) tools. Finally, techniques consist of step-by-step instructions, guidelines or advice to assist the completion of the phases or the project lifecycle. Design methodologies are mostly notably applied to project management and technological industries such as software development. In project management, design methodologies allow projects to be directed to achieve the expected goals within the given constraints. Technological industries also follow a very similar approach to project management. Methodologies can also be applied to everyday tasks, especially within the area of business. In retail, staff are often given guidelines on how to deal with customer complaints. Most notably, ALARA involves the steps of acknowledge, listen, ask questions, recap and act. This is in essence a design methodology which begins with the planning phase (acknowledge), the analysis and design phase (listen and ask questions), the support phase (recap) and implementation phase (act).

Renaissance and Baroque Eras: Art Comparison

Renaissance and Baroque Eras: Art Comparison Comparing the Eras of the Renaissance and Baroque Since the beginning of time Art has been used as a form of expression. With each historical art era came new advances and techniques. Each era was influenced by the unique characteristics, style and social conditions of its time. Although each era bought forth new forms and unique styles of art many historical art periods were influenced by an earlier period of history. The following essay will describe and explain the characteristics, style and influences of the Renaissance and Baroque eras as individual periods. It will also analyze painting from each period and explain the similarities and differences of both paintings; it will also discuss the relationship between the two eras. A look at the Renaissance The Renaissance era is known as the period of transition into modern day. The term Renaissance originated from the French language meaning rebirth, which precisely describes the period of the Renaissance. The Renaissance began in Italy and quickly spread across Europe between the 14th and 17th century. During this period Europe experienced large social, intellectual and economic changes. Europes ability to surface from the stagnated economy of the Middle Age had large effects on the period. Possibly the most significant and popular advancements made were in the cultural, social and political institutions. The progression into Individualism during the Renaissance made way for major advancements. This progression removed the traditional values of the Church and allowed individuals the freedom to explore the human mind, body and their surroundings. The issue of religion had a significant effect on the Renaissance era. With the Catholic Church tangled up in controversy over power, corrup tion, simony, nepotism and the Popes fathering of illegitimate children, many followers turned away from the Church and embraced a new reformed version of their beliefs causing a decrease power level for the Church. The increase of literacy also affected the Catholic Church, as believers learned more they realized that the Church was preaching only what they favored to the followers. Possibly the most significant religious event during the Renaissance history, was the Protestant Reformation, which was founded by Martin Luther in Germany. The new found views towards religion had major effects on society and their way of thought. Freedom from the Church allowed individuals to explore freely which resulted in a completely new way of life in all fields. (The Renaissance,n.d.) The Renaissance era allowed art to develop and mature far beyond the traditional and conventional religious subject matter to replicate human emotion and realism in art. While religion remained the main influence during the renaissance the origination and recognition of human form, expression and scientific study became very active influences in the arts. Painting and sculpting techniques developed greatly during the Renaissance. Artists began using new techniques such as linear perspective, laws of portion, balance and physical presence. The key distinctiveness that characterized Renaissance art includes an adoration and praise of the human figure and nature, realistic linear perspective and prominence on the association of light and shadow. Most of the best known artists and masterpieces were produced during the Renaissance period. During the Renaissance era famous artists such as Masaccio, Michelangelo, Raphael and Leonardo da Vinci created unique and untraditional techniques neve r used before. (The Renaissance,n.d.) A look at the Baroque period The term Baroque originates from the Portuguese language meaning irregular pearl. The era was dubbed the name to imply strangeness and irregularity. The baroque style began roughly at the end of the 16th century and lasted until the mid 17th century. The Baroque style first developed out of the Catholic spectacle and poise associated with the Counter-Reformation. Later, as the technique expanded north, it quickly became famous at royal courts, where it represented the rising rule of the new monarchies. The religious differences which begun during the Renaissance with the Reformation and Counter Reformation continue well into the 17th century. The religious conflict among the two groups influenced art greatly in this era. As a result of the Catholic Churchs Counter-Reformation, amazing churches were built, decorated and furnished to the extreme. Consequently, the demand for unique extraordinary religious themed artwork was great. As the economy flourished many European capitals began to raise, therefore the increase for architecture and decoration was high. (Guisepi, n.d.) Art during the Baroque period produced a sensation of progression, dynamic and apprehension. The technique of powerfully using distinction of light and shadow and a never-ending quantity of space is famous during this era. The presence of passionate spirituality and realism were also vastly utilized. Artists were famous for showing an individuals personalities, passion, emotions and thought merely through their facial expressions. Baroque art was a form of exaggerated Renaissance style art. Baroque painters utilized the fundaments of art distinctively from prior eras. In paintings lines were typically smooth and gentle; the color scheme consisted mainly of a single tone. The difference between shade and little was an essential technique. Time was particularly important to painters during the Baroque era. Artists viewed time as an assessable object. They believed time fades lies away leaving truth and justifies good over evil. The use of time would be a recurring theme throughout the Baroque era. Similar to the Renaissance, the Baroque artists ornamented the interior of grand buildings such as chapels and palaces. Along with art, the Baroque style surpassed the modern form of sculpture. Baroque sculptures were full of uniqueness, expression, and action. The sculptures of this period also expressed a passionate emotional bliss and creativity. (Guisepi, n.d.) Analysis Both the Renaissance and the Baroque eras created several of the most famous artistic works produced in the Western world. While the two eras illustrate distinctive distinction in work style and theme, nonetheless they reveal many characteristics in common. To better understand the similarities of the eras a comparison of two works of art from the two different periods is helpful. The two paintings that will be analyzed and compared are Leonard da Vincis Mona Lisa and Peter Paul Rubens The Straw Hat. Analysis of the Mona Lisa The woman portrayed in the Mona Lisa painting is known as La Gioconda or the Smiling One. The structure of the Mona Lisa forms a pyramid shape, her folded arms and hands serving as the bottom base, her shoulders and arms forming the sides and her head as the peak all connecting to form a pyramid. The support on which her left arm lays is hardly noticeable, extending to a vanishing armrest. Leonard da Vincis keen Renaissance period infatuation with features and detail is enthusiastically obvious in the painting. The smallest details such as the creases in her gown, the superior use of detail of the background, and the structure of her hair are accurately and thoroughly painted. The painting looks as though it was submersed in a smoky haze which was created by da Vincis expert ability to gradual blend one area of color into another without a sharp outline. This technique allows the viewer to recognize the shadows and light of both the image and background. The paintings lighting is sub missive, however extremely natural. The use of natural and realistic highlighting and shadowing characterize the shape, features and expression of Mona Lisa. Unlike her face, her dark tone clothing easily blends into the softly lit setting behind her, merging the work of art in the classical Renaissance manner. Regardless of the proficiently blended colors, the features of the scenery behind Mona Lisa are obviously noticeable, another distinctive technique of the Renaissance. The utilization of linear perspective is delicately understated due to the absents of individually positioned lines, but nonetheless are still present and noticeable, as the observer stares back into the scenery the vanishing point can easily be located behind the head of the figure. The stream flowing behind her, the distant mountains, the path and canal near the center of the painting are distinctive features of the painting regardless of the haze and create addition interest to the entire painting. ( da Vinc i, 1605) Analysis of The Straw Hat The subject of Peter Paul Rubens The Straw Hat is Susanna Fourment. In the painting Fourments stand is positioned to formed a pyramid structure. Resembling the structure of the Mona Lisa her folded arms also serve as a base, her shoulders and arms as the sides and her head as the peak all corresponding to form a pyramid like shape. The hat on her head is placed casually with a minor slant, which creates a line that cuts the peak of the pyramid. Her flared skirt which is slightly noticeably under her folded arms creates the sense of a second, shorter pyramid that is concealed under the first. In his painting, Rubens demonstrates the classic Baroque freestyle brushstrokes. This technique is noticeably observed in the features of Fouments dress and hat. Her laced cuff and the feathers in her hat are visibly identifiable; however their finer details are buried by the graceful flowing brushstrokes, which is a typical technique of the Baroque era. Rubens employed the classic Baroque method of strongly contrasting shadows and lights to highlight and focus on features in his painting. To create a naturalistic light in the painting the lighting was focus directly on Fourment. Rubens use of strong bold colors for Fourments clothes along with the contrast of color and texture among fabric and skin allow her to stand out and clearly portray her as the focal point of the painting. The backdrop of this painting is merely a mistily illustrated group of clouds with a hint of blue sky scarcely peeping through. As a result, the background of The Straw Hat painting is utterly inferior to the focal point of the piece. Without distinctive images in the backdrop to supply an allusion point, the use of linear perspective is unseen. ( Rubens, 1625) Similarities in both paintings Both artists treat the similar themed topic according to the technique of their particular periods. Both paintings illustrate a young lady in nearly identical poses, both bodies are positioned at a 75 degree angle with the head somewhat turned back in the direction of the observer. Both women have their hands carefully positioned under the bust in front of them. Both woman gaze towards the right of the viewer neither one stares directly towards the viewer. Both women display a slight content grin on their faces. Another similarity among the paintings is observed in the background of both painting. Both paintings create mysterious and foggy sceneries behind the woman. In addition Rubens composition resembles the Mona Lisa so much that many questioned if Ruben intentionally setup his painting that way. Differences of the paintings In the Mona Lisa painting da Vinci uses precise and magnificent technique in the details of the background; the eras passion for details is enthusiastically noticeable. On the other hand, the background of The Straw Hat demands no attention. During the Baroque era artist primarily focused on the main subject matter. Another difference in the paintings is the use of linear perspective, in the Mona Lisa da Vinici creates a clear vanishing point in the background of his painting, unlike Rubenss painting were he pays no attention to the background scenery and only focuses on the main subject. Another distinction in the paintings is the color scheme, in the Mona Lisa deep dark colors are blended smoothly with the background and the sfumato technique is used perfectly to bring focus to the details of both the image and background, in The Straw Hat bold daring color tones are used to make the image stand out, also instead of the sfumato technique Rubens uses the traditional Baroque techniqu e of combining strongly differing lights and shadows to focus on and emphasize the features in his painting. Relationship and connection of both historical eras Although both eras are unique in different respects, yet the eras share similarities and also continuing relationship. The Baroque era is said to have been generated at the end of the Renaissance era, which progressed to a dramatic, illuminate, energetic sophisticated form of art. The techniques of the Baroque art era united the sophisticated techniques and magnificent advances of the Renaissance along with the emotion, intensity and drama of the high Renaissance with the Baroque style of mixing the basic fundaments of the naturalist and classicist manners that are characterized by magnificence, energy and emotional enthusiasm. Many art scholars consider the Baroque style a representation and continuation of the Renaissance era. Similar characteristics of both eras include the use of light and color, focus on realism and idealism, strong perspective effects, religious themes and nude portraits. ( Myers, n.d.) To conclude the Renaissance and Baroque eras generated several of the most celebrated artist as well as masterpieces of all time. Although both eras share many similarities each era has its own unique characteristics and is unique in its own way.

Enzymes Essay example -- essays research papers

The structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction, called feedback inhibition. Enzymes are catalytic proteins; therefore they change the rate of a reaction without being consumed. This means that once and enzyme does its job it can still perform the same function as it did before. Organic catalysts change the rate of a reaction without being permanently changed. Enzymes are polypeptides that are made up of amino acids. Enzyme variable groups that are exposed are the places in which biological processes take place. These side chains, commonly called "R groups," make up the active site and catalyze the conversion of the substrate to make a product. These side chains are often called variable groups because they are often what determines the kind of enzyme it is, therefore determining what substrates it will bond with. A change in temperature or a fluctuation in pH can alter the enzyme’s structure. Anent temperature the alteration of the enzymes occurs when the temperature is very high and the enzyme denatures and is unable to perform the desired task. The temperature is so high that the active site of the enzyme changes and it is unable to bond with substrates. The pH at which different enzymes denature differs from enzyme to enzyme. Similar to too high a temperature, if a specific enzyme is at a pH at which the active site changes, the enzyme is unable to function. This illustrates how the structure of an enzyme is vital to its proper functioning. Allosteric enzymes differ in structure than the previous enzymes addressed. The extreme temperature and pH rules, however, still apply. Most allosteric enzymes are composed of two or more sub units, each having its own active site. The allosteric enzymes are constantly changing between two conformational states, active and inactive states anent functioning. This oscillation helps in the regulation of the enzymes. Enzymes function as organic catalysts, meaning that they are organic molecules (proteins) that change ... ...r to the allosteric site while the enzyme is in the inactive form will impede the ability of the enzyme to function. Cooperativity is when a substrate binds to the active site of an allosteric enzyme thus leaving the enzyme in active form and aiding in the binding of other enzymes to the other active sites of the enzymes. Feedback inhibition occurs when a metabolic pathway is turned off by the end product of the reaction. For example, the end product of a specific reaction may be an allosteric inhibitor to the specific enzyme that makes the product; this prevents the enzyme to make more products when they are not needed. As the product accumulates the product slows down the synthesis or products. In conclusion, the structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction, called feedback inhibition.

Cooperativity is when a substrate binds to the active site of an allosteric enzyme thus leaving the enzyme in active form and aiding in the binding of other enzymes to the other active sites of the enzymes. Feedback inhibition occurs when a metabolic pathway is turned off by the end product of the reaction. For example, the end product of a specific reaction may be an allosteric inhibitor to the specific enzyme that makes the product; this prevents the enzyme to make more products when they are not needed. As the product accumulates the product slows down the synthesis or products. In conclusion, the structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction, called feedback inhibition.

Aristotelian :: essays research papers

Can a Child be Virtuous?   Ã‚  Ã‚  Ã‚  Ã‚  In this paper I will argue against Aristotle and his idea that children cannot be virtuous, as we discussed in class. I will do this by giving concrete examples that a certain widespread religion believes in this virtuosity of a child. I will also use a more common example that occurs all the time in America.   Ã‚  Ã‚  Ã‚  Ã‚  Aristotle says that children cannot be virtuous because virtues are something that, to be acquired must be practiced over and over again. A child has not had enough practice, time or understanding of what he is doing to be considered virtuous. However, I think that there are virtuous children, and that not only â€Å"Athenian gentlemen† are virtuous, but some other people also, these including children.   Ã‚  Ã‚  Ã‚  Ã‚  For my first example let us consider the religion of Tibet. These people elect a child, in fact a newborn to be in charge of their entire religion, this child is the Dali Lama. They think that this child is holy, and pure. Obviously they think that he is good, and virtuous. He has the most power in their entire religious system of beliefs. There are many many people who believe in this religion, and have done so for centuries. This child is trained from a very young age on and is selected to lead a virtuous life. He practices things that Aristotle would view as virtuous, for example, courage, pride, justice, and temperance. This child could easily get in more â€Å"practice time† of virtuous activity than the average person, even more than a person who is on their way to being virtuous who is an adult. According to Aristotle’s own beliefs, there is a certain amount of virtuous activity that must be done to become a virtuous person. This child could easily do as many virtuous activities by the age of 10 as say someone who is 20 in another situation. That is one problem with Aristotle’s theory, when does the virtuous activity start adding up so that one may become a virtuous person? How long is someone considered a child? Do his activities not count until he reaches a certain age, and then suddenly there is a breakthrough and they start to count? I think not. A good act is a good act no matter what the age, if the intent is correct.   Ã‚  Ã‚  Ã‚  Ã‚  Those who wish to support Aristotle could in a certain context use the Christian religion to counter the Dali Lama example. Christians believe that all â€Å"men† are born sinful and not good. There is no way that a child is any better than anyone else. The Dali Lama would be considered just

MIC :: essays research papers fc

MIC   Ã‚  Ã‚  Ã‚  Ã‚  Products and machines made of steel have long been considered to be solid, strong, and very durable. The effects of general corrosion, â€Å"rust†, were considered to be the only factor limiting a steel product’s ability to last forever. It is thought that the general corrosion of steel is recognizable and its effects are easily limited by the application of various coatings and paints. Only in more recent years have the destructive effects of Microbiological Influenced Corrosion, â€Å"MIC† been discovered. Today MIC, whether it is on the bottom of a barge, in a water pipe, or in a nuclear power plant’s cooling tower, has evolved into a billion dollar problem. To cure this problem, I have created a device that cleans MIC out of the bilges of barges operated on the Mississippi River system. The bilges or confined void spaces have never been able to be cleaned due to the extremely tight or inaccessible area in which you would have to work. I found that most barges have a coating on the steel which provides a food source that the MIC bacteria absorbs (eats) and the bacteria’s resulting acid actually can penetrate the steel barge. Businesses that clean these barges to rid them of the MIC and the organic coating can charge as much as $10,000 to do just the ends of the barges, which is an area less than a tenth of the entire barge. The inner bottom void spaces which take up the remainder of the barge’s area are only 15† high, 27† wide, and 28’ long. Some barges have as many as 90 of these confined spaces, and none of them have been cleaned because their limited size makes them inaccessible. With the completion of my product it will be the first time the inner bottom void spaces of a barge can be cleaned. This will mean the MIC and its food source, the organic coating; will be completely removed from the barge for the first time since its original construction at the ship yard. For many years, MIC was incorrectly identified as the corrosive effects of saltwater on steel in ocean going vessels. Although salt certainly does have a corrosive effect on steel, it was not until more recent years that the term MIC was originated, and its effects are only starting to be discovered. MIC is responsible for the accelerated corrosion in ocean going ships, water storage tanks, fire protection sprinkler systems, commercial and military aircraft, and most recently discovered affecting the inland river barge fleet.

Ad Strategy Report Essay

Vermont’s famous ice cream markers, Ben & Jerry’s, started the City Churned campaign summer of 2013; where five major cities voted in traditional and non-traditional ways to create a unique flavor that capture elements of the city. The five major cities were Seattle, Portland, San Francisco, Washington DC and New York City. Ben & Jerry’s also teamed up with local favorites to make the flavor even more represent the city it is for. At the end of the summer, Ben and Jerry’s served the final product the city chose at community events. Ben & Jerry’s objective from start this campaign was of course to increase sales, but also to create a deeper connection was their consumers, Mike Hayes, Ben & Jerry’s assistant digital marketing manager, told Adweek. Another main objective of the City Churned campaign was to remind people of the social mission the company stands for and the importance of local roots. Their social mission is about keeping ingredients real (no GMO’s) and doing what is best for the planet at large. The company wanted to also focus on the importance of local roots by using products from companies local to that city. There were main three strategies that Ben & Jerry’s used in order to meet their objectives. The first strategy was having an interactive campaign. They made it so people were voting by doing everyday life activities, such as what turn gate you use when heading to train. The second strategy was taking a modern twist on crowdsourcing. They used the traditional method of having a website where people would directly vote right there, but also used new different ways to gather even more input. Ben & Jerry’s teamed up with transportation services popular to the city to count votes as well. In New York City, the cabs headed uptown counted as a vote towards peppermint, whereas a cab headed downtown was a vote Fairtrade vanilla. In Portland, they watched the men entering Cartopia and whether he had a mustache or a  beard was vote for different flavors. The last strategy they used was making local elements the main part of the campaign. This made locals to the city or people who knew the place interested in what was being picked. That created a lot of free press for Ben & Jerry’s. Local newspaper throughout the summer kept track of the voting and what was happening. Some of the techniques that Ben & Jerry’s used to accomplish the goal was repetition. Their name was all around the cities, especially at local hot spots. They also promoted the product being special to each city by capturing the local elements and flavors, and letting the people decide what flavors and elements really show the city. Another technique used was creating excitement, which created participation. The whole campaign was based around the people getting what they wanted. People took pictures are local monuments and used the hashtag for their city to vote and get into the campaign.
