Quench and temper - Lab Report Example The first step in a quench and temper process is the intense heating that that aims at ensuring homogeneity of the steel’s elements and requires a temperature that is above the component’s transformation potential. This therefore eliminates possible asymmetries that reduce strength of normal steel. The sudden cooling then yields a â€Å"body centered ‘martensite’, which is hard† but is brittle (Black and Kohser, 2011, p. 133). The temper process however, defines a reheating of the material, at moderate temperatures to reduce the brittleness towards more malleable material (Black and Kohser, 2011, p. 133). The achieved strength of the material however depends on a number of factors. One of the factors that determine the achieved strength, and toughness, of a material from a quench and temper process is the level of orientation of microelements of the materials. Quenching and tempering process alignS the microelements to a level of homogeneity, a process that is done at the tempering process. Homogeneity can however only be achieved if the material is heat to a higher temperature, above the transformation level of each element of the material. A lower temperature exposure, relative to the elements’ transformation temperature is therefore expected to have little impacts on the achieved level of toughness and strength of a material while a high temperature heating is likely to achieve an increased level of toughness and strength. This factor directly relates to the nature of treatment (Shah, 2007, p. 58). The nature of treatment that a material is subjected to also plays a role in the acquired strength. Inappropriate processes are for instance identified with lower gained strength and hardness. In some cases however, poor treatment conditions even worsen a material’s strength and hardness to make it weaker than its original condition. Other factors that affect the effects of

Critical Issues Essay Example | Topics and Well Written Essays - 500 words

Critical Issues - Essay Example This sorting out procedure will require following of five stipulated principles some of which include provision of funds to states with lowest capacity to raise their own revenue, consider the effects of fiscal responsibility and provision of clear separation of responsibility between the state and local government (Foundation Fiscal Partners, 1999). I was not aware that there is controversy of finances. I always assumed each state received its funding of basic projects such as education and health from the federal government and then they dealt exclusively with the delivery of the services. I also had no idea of the fat that these duties and responsibilities even though they intertwine have separation through the constitution. Smith, Greenblatt and Mariani, (2007) sheds more light by use of the constitution of the roles which should be performed by the two in regards to finances. The tenth amendment for example explains that the state carries out the most mandates in regards to the running of the state and federal government only comes in when it is mandated by the constitution. The main themes include the relationship between state and federal government and how the tenth amendment and the commerce act and even the constitution itself have tried to differentiate the duties and responsibility to no avail. There is also separation of duties of the state and local government which are slightly intertwined. The other theme discussed in the reading by Smith, Greenblatt and Mariani, (2007) is the division of labor in the state and the roles of some of the people such as governor. This also leads to the theme about the responsibilities that the state has towards the towns and counties. The controversy between the powers and laws of federal and state government have left me opting for the federal government to leave the states to run their own affairs as best as they can without interference from the federal

Role of US in the Arab-Israel Conflict Essay Example | Topics and Well Written Essays - 1250 words

Role of US in the Arab-Israel Conflict - Essay Example This essay talks about the Arab-Israel conflict which is one of the main threats to the world peace because of the multi dimensional aspects it covers. A lot of people around the world believed that the current trends of terrorism have its roots in the Arab-Israel conflict. The US foreign policy towards this issue questions by many because of the soft corner it keeps towards Israel. Though the US tried immensely to convince the world that it has taken a neutral policy on this issue, nobody takes this claim seriously. There are several lenses through which one can interpret US policies aimed at the Arab-Israeli conflict like, contrasting national interests, special relationship politics with Israel, bureaucratic politics and individual beliefs. Because of these multi dimensional aspects of the conflict, the reaching of a compromise is extremely difficult. The conflict is filled with regional, religious, political, cultural and communal aspects. It is not easy to address each problem s eparately. For example, Avineri Shlomo wrote that in the post-September 11 context, Israelis hope that the United States-now a victim of massive domestic terrorism-will have more sympathy for them while Palestinians hope that the United States will revive peace talks, and thus solidify Arab support for the war on terrorism. The September 11 attack on the trade center has, in fact, turned out to be a blessing for Israel. It is only after this attack the communal dimensions of terrorism has come to exist.

Miracles week 3 Essay Example | Topics and Well Written Essays - 500 words

Miracles week 3 - Essay Example He works through Noah whom he instructs to construct an ark that He would use to save only eight righteous people (Genesis Chapters 7 and 8). The miraculous saving of Noah and his family is extraordinary and it portrays God’s supreme authority. In a similar manner, God also appears to Moses in the form of a bush in flames. The bush was not consumed at all by the fire (Exodus chapter 3). Cognizably, this is an extraordinary happening as it defies the laws of nature. That way, God demonstrated that He is above nature and human understanding. Moving on to the New Testament, Jesus raises Lazarus from death was miraculous (John chapter 11). When Jesus died, He also resurrects (Luke chapter 24). Reviewing these two events, it is observable that life is eternal and that God is life. In our contemporary society, if one performs such a miracle, the power may be attributed to the person rather than to God. The truth is that one can perform miracles through supernatural powers alone. During the call of disciples, Jesus performs a miraculous catch of fish (Luke chapters 4 and 5). That makes Peter recognize Jesus as the Son of God since he knows that only God performs miracles for the good of the people (Elwell, 1996). From this, it is observable that miracles are limitless. In conclusion, the Biblical concept of a miracle explains that God is Almighty, all-knowing and present everywhere. He manifests His power through people. When one performs miracles consistently for the good of the people, it is a revelation that the person is a true messenger of God. Elwell, W.A.

Oil Market Essay Example | Topics and Well Written Essays - 1000 words

Oil Market - Essay Example In case the price of oil went down, then the price of such commodities were also stable, and if the price of this commodities went down, then these products also follows such occurrences. If we are to analyze this, one might ask, what is with oil that it has the power to control different scenario On the second thought, analysts particularly economists suggests that it is not only the oil that can have such a trend, but almost every product that is available to the market. This kind of occurrences is dictated by the demand of the customers and the availability of the product. In this case, the law if supply and demand comes into picture. Therefore, what is the law of supply and demand Before analyzing such a law let us first scrutinize the meaning of demand and supply with regards to economics perspective. The Columbia encyclopaedia (2005) described supply and demand as, 'Supply refers to the varying amounts of a good that producers will supply at different prices; in general, and a higher price yields a greater supply. Demand refers to the quantity of a good that is demanded by consumers at any given price. According to the law of demand, demand decreases as the price rises.' Upon analyzing this premise we can now have a clearer picture of what supply and demand has something to do with the oil market. It is now clear that oil will be regarded as the supply and the wanting of the consumers to get the oil to compensate their needs is the demand. Upon looking into this scenario, one might conclude that the oil as a commodity has the power to dictate its price regarding to the demand of world market. As stated on the first page that almost every human activities on earth needs the consumption of oil, therefore, it would be safe to conclude that there is a huge amount of demand for oil. From cooking meals, generating electricity and running automobiles, this kind of activities consumes oil. If we are to base such things with the aforementioned premises, the price of oils would tend to go up and it is due to the law of demand. The law of demand is defined as " a microeconomic law that states that, all other factors being equal, as the price of a good or service increases, consumer demand for the good or service will decrease and vice versa (answers.com 2006)." In this regard, the flow of the prices of oil would tend to go up if we are to base this phenomenon to the worldwide demand of oil. All over the world, oil is a necessity in life. On the second thought, one might ask that why it is that oil can dictate the flow of economics of some countries in the world Why is it expensive than other necessities The answer would be, it is because of the availability of the product. If we are to compare oil's prices in the majority of Middle East countries where oil is abundant against distant countries such as the Philippines where there is a minimal source of the said product, there is a huge amount of difference with regards to the amount of oil. In countries such as Saudi Arabia, UAE, Kuwait and the likes, oil prices ranges from $20-$30 centavos per liter to judge against $1.2 per liter. This is due to the following reasons: 1) the fact that oil production is limited, then the priorities of the distribution of oil would be in the countries were it was extracted and therefore, counties

Operations Strategy Essay Example | Topics and Well Written Essays - 2500 words

Operations Strategy - Essay Example For instance, it is not only enough to focus the whole energy of an organization on production activities, but considering that there are existing processes in the business world as it continuously evolves, other aspects need to be substantially focused and even strategic actions have to be implemented. History The existence of business itself paves way to the formulation of operations strategy. Businesses ended up to the creation of business strategies. These led to the formulation of effective operations strategies (Waters, 1999). Businesses have to function efficiently and this is the reason why strategies are necessary to be integrated with the whole business operation. In fact, this is evident on how the United States’ business evolved over time. The evolution of business policy and management started between 1930 and 1960 as highly influenced by American dominance in the global market (Amatori & Jones, 2003). It is during this period that business was considered as an is olated American subdiscipline. During this time, the United States has become one of the leading countries that introduced business sophistication into the world. This resulted to significant innovation and major changes how the business including its operations was conducted. Throughout history, businesses evolved and primarily this is sped up by the onset of globalization in the modern business world. In globalization, there is increasing interdependence between national systems through different aspects including trade, military alliance, domination and cultural imperialism (Waters, 2001). It is not surprising therefore that the business world has significant changes over time due to the fact that interdependence between nations existed. This includes maximization of resources and operation. This is the very reason why business has become international and has turned into a good opportunity for international organizations to maximize their operations and resources. As the effect, each organization that tries to compete with each other is trying to create competitive strategies for their competitive advantage (Porter, 1990). For instance, marketing strategies existed and companies are after of stimulating needs not just relying purely on production oriented operation approach (Boone & Kurtz, 2006; Kotler et al., 1999). In short, the need for operations strategy is necessary in order to compete. The need for innovation is not just on producing new service or product offerings, but there is substantial consideration on business operation approach in which strategies are become its integral parts in the process. In other words, as business itself evolved, its corresponding operation which has been an integral part in its existence has also become so involved with business strategic formulation. This is in line with the creation of competitive advantage due to spiraling growth of competition everywhere most especially that the world has become so compressed when it comes to interdependence in trade. Thus, every organization is expected to formulate their very own operation strategies in order to sustain their ventures and even maximize their full advantage in their respective industries. Relevance It is important to understand that the relevance of operations strategy at present can be traced back to how business has substantially evolved. Operations element of a business
