Enzyme - Lab Report ExampleConclusively, increase in temperature increases the activity of the enzyme up to the maximum level, and further increase leads to the denaturing of the enzyme.For all chemical reaction to proceed within a cell, activation energy is required to cause and complete this process. This is made possible by the use of enzymes. Enzymes fundamentally work within the cells and their ability determined as a result of their specificity brought about by the shapes from the amino acid sequences (Daniel and Danson 2740).The enzymes have active sites on their surfaces to accord the binding of a substrate through the help of coenzymes to form enzyme-substrate complex. The chemical reaction thus converts the substrate to a new product then released and the catalytic cycle proceeds.Many factors, for example, pH and temperature affects the way enzymes work by either increasing the rate or determining the type of product produced (). The report, therefore, analyses the effect s of the enzyme peroxidase in metabolic reactions and determining its optimum temperature in the reactions.The effect of temperature was then determined on the activity of enzyme peroxidase through monitoring its effects under different temperatures of 4, 32 and 600C on the dye guaiacol when it turned brown.Temperature increased from 40 C to room temperature of 22.20 C resulting to the increase of the peroxidase activity. This explained that increase in temperature up to the optimum point lead to the increase of the breakdown of guaiacol dye to color brown with intensity increasing up to this optimum point. Further increase in temperature to 60C denatured the enzyme and therefore the exertion of the brown color stopped and its intensity reduced.From the experiment therefore, the optimum temperature for peroxidase is at 22.20C from graph on figure 1. The temperature effect is reversible in the case whereby the peroxidase is uncovered to temperatures that negatively affect

Why does the US continue to label Hezbollah as a terrorist Research Paper

Why does the US continue to label Hezbollah as a terrorist organization - Research Paper ExampleThe US perceives Hezbollah as a terrorist organization and is constantly urging the European nations and the United Nations to brand it a terrorist organization. The British have the perception that it has two wings, one that is policy-making and the other, the military which is responsible for terrorism. This claim has since been refuted by Hezbollah leader Hassan Nasrallah (ITIC, p. 2). Other regimens mostly Moslem and Islamic nations, consider Hezbollah a legitimate resistance group. The problem is, the branding is based on governments perceptions (Stewart 137). Terror is perceived as war against Islam. So wherefore does the US continue to label Hezbollah as a terrorist organization, yet the organization has well defined manifesto of resisting Israeli invasion, and any other colonialist invasions? The aim of this essay is to explain the other side of the organization. It is to show that Hezbollah is not a terrorist organization, tho a governmental fellowship that fights against invasion as well as development. It is also to show that the branding of the organization as a terrorist organization needs more facts and explanations as to why. ... This shows how dominate the organization is, a characteristic of a political party. Anti Defamation League, notes that Hezbollah has been labelled as a terrorist group, but its actions have shifted its political baulk to advocating for the electoral interests of the Shiis community. Shii community is about 40% of the population of Lebanon (2008). Hezbollah is a political entity that does not only fight against Israeli invasion, but for its existence and power as well. In May 2008, an agreement was formed between Lebanons western backed government and Hezbollah. This was meant to end a political crisis that had lasted 18 months and was on the brink of causing a civil war in Lebanon. From the agreement, Hezbollah and it s allies obtained prohibition powers over the government decisions and were awarded 11 lay out of 30 cabinet seats (ADL 2008). In 2009 parliamentary elections however, Hezbollah and its allies were defeated and remained with 11 out of its 128 seats. A new unity government formed in November, which now holds two cabinet seats belonging to Hezbollah (ADL 2008). All these are indications of a political party with its own strategies of acquire power from the Lebanese government. There are several reasons why Hezbollah is considered a Terrorist country and these will be discussed, but the main reason why Hezbollah exists in the first place is because of the Israeli Invasion. The formation of Hezbollah explains all their actions. The Formation of Hezbollah Hezbollah was founded in 1985 and is a major political force (Tucker p. 529), although considered a terrorist group or organization by the US, the British and some other countries. In 2001, President George W. Bush in his speech to a joint session of congress, noted that there

Exam questions - Essay ExampleEach division in the larger firm is responsible for the maximisation of its profits and production.The central office overlooks the other divisions with the primary responsibility for formulating the overall strategy for the entire line of work but not directly controlling the operations at the divisional levels. Large firms have adopted the M-form as opposed to the traditional Unitary structure (U-form) in which the operations of the business are centrally managed with no independence given to either sub-division. While Chandlers multidivisional form advocates for growth through diversification across industries, markets and products, Williamsons M-form does not make any reference to diversification. The multidivisional form explained by Chandler supports the delegation of complete power and authority to the divisions while that of Williamson is for the retention of control by the management at the major company.The vantage of the M-form over other di visional structures is based on its ability to combine the economies of scale and different brand benefits of a large collection while maintaining the practicable flexibility. It provides the central optimisation level within a company (Besanko, 2010). Unlike other divisional structures, the M-form solves the dilemma of the differences observable in profit maximisation strategies, business needs, and output across the divisions when organisations grow to be too large. Each group, with its independence and flexibility, can be kept in the centralised profit maximisation expectation. Williamson proposes a perfect coordination between the general direction of the business and the daily operations of the divisions under the M-form structure. However, there lies a limitation on the wide adoption of the M-form that arises from Williamsons requirements for this divisional structure. The largest

California Vaccine Mandate Bill Research Paper Example | Topics and Well Written Essays - 1500 words

atomic number 20 Vaccine Mandate Bill - Research Paper ExampleInitially, the philosophical exemption law protected some groups of Americans against needful vaccination based on their religious and philosophical perspectives of them. It means that while it is almost necessary that children are vaccinated before they enter school, some children were exempted. However, the California vaccine mandate bill forget eliminate the privilege starting 2016 (McGreevy, 2015). thitherfore, the implication of the new bill is that families with negative religious beliefs will no hourlong be exempted. The new bill demands that a greater number of Californian children is vaccinated before they enter schools. According to the LA Times (April 22, 2015), the Senate passed the legislation on Wednesday 28, 2015 and will become a law beginning 2016 (McGreevy, 2015). The bill also provides that have negative perception of vaccines as a way of protecting their interests. There is a question of how suitabl e the proposed legislation is towards safeguarding of the rights of religious minorities in the state. While there is an acknowledgement of the rights of minority groups in the state, the new legislation will overturn such a privilege. The rationale for the deduction is that as some parents already complained, the number of children in schools will go lower. The reasoning is simple because parents with such beliefs will opt to keep their children away from schools as a way of protecting their interests. Some may argue that the legislation provides for parents with such opinions to home school their children.

Writers choice - Essay ExampleThe short cuff gloves exposed the wrist to say-so injury prompting players to start attaching specially molded malleable to the front part of their elbow pads to protect the lower part of their forearm (National Hockey federation 9).Ideally, the evolution depicts the significance of plastic material in making ice hockey skates where plastic pads and fiberglass replaced leather shoulder and elbow pads to heighten protection. With a special(prenominal) focus on the impact of plastics material on hockey sticks, pucks, skates, and safety, we can derive how plastics revolutionized ice hockey. Indeed, plastic has revolutionized traditional hockey sticks that were initially wooden via nanotechnologies that enhance the durability and speed of handling hockey sticks (Canadian Plastics diligence Association 1). Moreover, manufacturers use plastic material to make hockey pucks through modern technologies like vulcanization. more or less specifically, plastic materials advanced hockey skates that initially had leather with metal marks (Canadian Plastics Industry Association 1). Unlike old skates, the modern skates have a protective plastic cowling made of a major polymer, high-end polyvinyl chloride (PVC) (Canadian Plastics Industry Association 1). Indeed, the PVC is dominant in covering the lower half of the hockey boot (Canadian Plastics Industry Association 1).Modern manufacturers of hockey skates rely on PVC polymer subject to its good insulation properties. Indeed, PVC can only start decomposing when the temperature exceeds 140 C since it has a melting point of about 160 C. Moreover, the polymer has a small linear expansion coefficient and good flame retardancy that enhances the sliding action of the skate blade and skating speed. This relates to its high hardness and good mechanical properties. Indeed, with a thermal coefficient of expansion of 80 x 10-6 and density of 1.38 g/cm3, PVC promotes the production of hockey skates that generate less

Poetry essay Essay?How does Owen Sheers use language, form and structure to explore ideas roughly separation and division in Winter Swans? The Poem Winter Swans seems to convey a strong launch of natural love. The verse form begins with setting a tantrum of a peaceful day, where nature seems to be stilled by and by the torrential weather that is referred to in the first line through The clouds had given their all. It goes on to say that in that respect was then a break, and throughout the poem the poet uses words such as silent and rolling, stilling and slow-stepping to capture this scene of peace and serenity, as if the sphere was resting after being thrashed about by a storm. With the idea of a natural love, there comes the confusion and the inartificial knowledge that love is not materialistic, a stamp and something that can not be brought on by force.Through all natural love stories come feelings of hurt and division. A separation that brings the subjects closer and strengthens the emotion. Sheers uses the theme of leaving, and then returning, or rage, and then peace, or the unknow, and then the known to reoccur throughout the poem, compensatetually strengthening the love, which could be argued as the main emotion of the poem. The poet also uses imaging such as lakes and swans, to symbolise the peacefulness, and also to symbolise love.You notice words that show the subject is not alone, with we and our. These words and also the motion of the swans, the lake, and the peacefulness be foreshadowing that the poem exit take a turning onto love that is more literate. However I dont think that the poems theme is so much about love in particular, but about a natural love, a natural pull that brings two people together even after hard times.Sheers uses Swans as a metaphor of love, the way swans will smoothly dip in and out of the water, and how they are known to curve towards and away from each other as if dancing on ice. They are the perfect examp le to show the way love will hook on away and then come back. He uses vocabulary ranging from silent and rolling to righting and rough to show the separation and how quickly the emotions get confused, and how quickly compassion will turn into anger, and vice versa.The poem begins referring to this in the first stanza with weather, as raging storm. And then a break. The poet then adds on in which we walked, showing maybe that the subject and whoever they are with also went through a hard time, but are now peaceful along with the nature. In the fourth stanza it describes the swans halving themselves in the lightless water, to portray a hard time, but then returning again like boats righting in rough weather It then moves onto the poems only piece of speech, they mate for life. Which rounds off the conclusion of the theme of the poem, that although there are hard times, they will always be pulled back together. The poem then shows this also applies for the people, as at the beginnin g of the poem it describes them as being silent and apart, but right at the end it shows them holding hands, symbolising how they are together. The poems theme is concluded with comparing them to a pair of wings settling after flight, to show that finally, the emotion has strengthened, and they can settle after the confusion and separation.
