Science and Materials for construction and the built Enviroment Essay

Science and Materials for construction and the built Enviroment - Essay Example Its strength and durability make it a great choice for structures exposed to high amounts of stress, such as weather, heat, large amounts of applied force and constant usage† (LaRoche, 1999). Modifying the chemical structure of the alloy permits steel to have enhanced and multiple uses. It has many other benefits apart from construction of roads and buildings, such as building of ships, cars and every other means of transport. It can literally be said that steel is unconstrained in its possible benefits. It is a major element in the construction of home appliances, automobiles, and shipping containers and various other machines. 2. Copper It is a thin wired metal with a high-level of thermal and electrical conductivity. It is used as a conductor of electricity and heat, a building material, and as a constituent element in various metal mixtures. The low stiffness of copper describes its huge electrical conductivity and, therefore, also high thermal conductivity, which is the se cond most important feature among pure metals at room temperature. This is since the resistivity to electron transport in metals at room temperature frequently derives from dispersion of electrons in thermal atmosphere of the network, which is comparatively nullified in case of a soft metal. â€Å"The maximum permissible current density of copper in open air is approximately 3.1?106 A/m2 of cross-sectional area, above which it begins to heat excessively† (Phillip, 2006). Electrical conductivity is a vital property in electrical wiring technique. Copper has the maximum electrical conductivity ranking among all non-precious metals. A distinctive combination of high strength and high ductility enables copper to be perfect for wiring systems. In electrical systems, high thermal conductivity is necessary for dispersing waste heat, mainly at terminations and links. It is also necessary for dropping energy consumption appropriate to the creation of waste heat. 2. Aluminum Aluminum i s a metal similar to copper, steel, brass, zinc, lead and titanium. It can be dissolved, radiated, created and developed like the aforementioned metals and it also conducts electric current. The strength and durability of an aluminum mixture differs generally, not only accordingly of the elements of the specific mixture, but also as a result of heat treatments and production procedure. Aluminum is a tremendous heat and electricity conductor and in association to its weight, it is approximately twice as high-quality a conductor as copper. This has led to aluminum being the main generally applied material in main power transmission approach. 3. Timber Timber is light, strong and reliable form and timber construction is easy and secure than steel or concrete construction material. Good featuring, coating and protection ensure that goods produced from timber are durable. Though many buildings become outdated and are destroyed long before the ending of their usual lives, timber construct ion properly planned and preserved could have an imprecise life. The input to extended life provides security from weather, insects and decomposers, with the help of fixed design featuring, surface coating systems, collection of durable types, and stabilized treatment procedures. The flexibility and strength property is â€Å"due to the (abundance) of interlocked fibers to provide strength. The direction and structure of the cells also effects the strength of the timber, straight grained

Goals Essay Example | Topics and Well Written Essays - 750 words

Goals - Essay Example The first short term goal is communicative competence, communication is the key these days and it is very important to be good at receiving and sending messages. The following procedure will help in understanding this goal. Using language in authentic is the first step towards achieving this goal, banning the use of slangs in the classroom will help in facilitating this goal. Once this is done, providing the appropriate context is the next immediate target, students whose grammar is weak must be worked upon if the goal of communicative competence is to be achieved. The peers will play a pivotal role in this exercise, each student will evaluate the performance of their peer, and this will also facilitate team work in the classroom which will benefit the students in the long run. The last target which will help in achieving the goal of communicative competence is by making the students aware of the cultural use of language; this is extremely important and should be done by every teache r. The following section of the paper will shed light upon the medium term goals (6 months), ways which will be used to achieve this goal will also be comprehensively presented. Encouraging collaboration in the classroom is essential and every successful teacher manages to achieve this goal. ... Students will feel that the collaboration has improved when they work in groups and try their best to achieve the goals set for them. Another important step is to give freedom to students so that they can use language in the way they want, this will help the students learn from each other. Different students will use language in their own way; the teacher must ensure that the students use the language in the right way so that no student learns anything undesirable. Three important things must be taken care off when working towards this goal, the teacher must ensure that there is no communication gap, each activity must have a defined outcome. For instance, drawing a map is an activity which is task oriented and perhaps the best example of a task oriented activity. The teacher must also ensure that there is a time limit set for these activities so that the students can learn within a specific time limit. The long term goal (12 months) would be to facilitate mastery of a field; this is extremely difficult and requires a lot of diligence. â€Å"Your classroom is a training ground not only for future study in your field but also for many aspects of life. Great teachers help students master the fundamentals of their subject matter, which will pay off both for advanced study in their field and for students’ everyday understanding of the world.† (Teaching Goals) These goals will be measured by maintaining a diary which will record events on a daily basis, at the end of the week results will be analyzed. Students will be engaged in leisure activities should the results be good, else more efforts to accomplish the same goals will be put in. At the end of a three-month period if only 50% of the goals are met the

Information Systems and Business - Essay Example In this background, this paper analyzes the questions where these researchers make significant compromises and who does the better job of operationalization in their research article. In their article, Hirschheim and Sabherwal make significant compromises when they deal with the issue of alignment between IS and the business strategies which has traditionally been a key issue facing IS management. Due to insufficient research being conducted on how such alignment is achieved and sustained over time, the authors find it difficult to conceptualize and operationalize their original variables. "Thus, our view of strategic alignment focuses on an organization's ongoing efforts to establish and maintain a series of interdependent relationships between business and IS strategies. These relationships involve the movement (i.e., change) of business strategy and/or IS strategy in such a way that the two are in alignment." (Hirschheim and Sabherwal, 2001, p. 87).

Life Course Theory Research Paper Example | Topics and Well Written Essays - 1500 words

Life Course Theory - Research Paper Example The life course theory can best be internalized by analyzing life occurrences in respect to stages in lives, turning points and routes which are all engraved in the social school of thought. This ranges from personal traits, the environment around the person, educational differences and the family or community status. Ingredients of Building a Criminal The emergence of a criminal is attributed to two main sources of influence on the life of an individual: transitions and trajectories. A transition comprises of the periodical short lived occurrences or decisive moments that create a particular life change like parenthood, marriage or divorce (Glen, Johnson & Crosnoe, 2003). Trajectories on the other hand refers to a route over the course of life which entails long lasting trends or patterns of occurrences like the history of the family and state of employment. Notably, there is a key role played by transitions in the course of oncoming trajectories (Heather and Farrington, 2001). Adap tation of an individual to a specific transition can result into change of course of the person’s life into a respective trajectory. Childhood experiences can have a great impact on occurrences in the adolescent stage and later into adulthood the same manner adolescence or adulthood events can shape later trajectories. If a child is exposed to too much criminal activities or violence, there is likelihood that the child or the adolescent will modify into one in his or her future life. Besides, exposing an adolescent to rejection in a social group increases the chances of the child developing into a violent adult. This is because the person has a tendency to feel neglected and thus the only way to obtain attention is by resolving to be a violent person. Provided this, transitions or occurrences at various stages of life can have a permanent effect on various consequences during a life course. Eventually this can lead into a one main trajectory or pathway. Environment Most crime s in the inner city emerge as a result of the environment a person lives and the kind of exposures the person is subjected to. As mentioned earlier, this falls under transitions. For example; the type of housing one dwells has a major impact on the life course of the person. This coupled with a desire to live in a decent apartment beyond the capacity of earnings of the person will automatically make the individual to attempt earning beyond his/her means. The individual may resolve to obtain the house or money by any fraudulent means which result into change of a life course. Besides, family structure has a greater role to play in this scenario. The family structure dictates the form of education a person acquires. According to Heather and Farrington (2001), the family is the corner stone of a human community. Children or adolescents who are constantly rejected by their fathers and mothers, those who are brought up in homes with significant level of conflicts and those are not adequa tely monitored are exposed to risk of developing into delinquents. Deborah, et al. (2002) assert that justice or fairness can be executed in a better way when the young individuals are directed on the best paths by involving the family members in Juvenile crime proceedings. It is vital for the society at large to understand the impact of family make up in getting to roots of delinquency. The structure of a family is one of the profound socialization foundations in one’

Response to Evolution questions Research Paper Example | Topics and Well Written Essays - 1000 words

Response to Evolution questions - Research Paper Example In addition, all human beings have a common ancestor in some part. Hence all living organisms connect or relate through the tree of life in some respect. The second most common feature is that only the fittest of organisms survive and reproduce offspring. Evolution can be noted in various organisms such as butterflies. Butterflies have modified their shape, color etc. over time to adapt to the environment in which they live. Evolution has also affected humans in many ways, and, theorists believe apes are the predecessors of evolved species called humans. The authors, Hughes et al. observe that humans share nearly 95% of their DNA structure with chimpanzees who are considered closest animal relatives to humans. Since evolution has come into the knowledge of people, a conflict between religion and science has emerged. Evolution is primarily based on ideas and concepts taken from religion. Bascom argues that the concept of creation and evolution are not contradictory and, therefore, should be studied together in this respect. Very strong controversy erupted when Charles Darwin presented his theory of natural selection in the year 1859. The author, Myers states that the concepts, which were presented, by Darwin altogether changed the human ideology related to evolution and how we study the human race today. Evolution can be regarded as the mutation which takes place in an organism in consecutive generations. Heng postulates that predecessors often inherit such changes and evolution explains the variety of such changes at each and every level of organic structure. Natural selection is a slow and steady process by which biological mannerism becomes common in any population of an organism. This is the primary mechanism of biological change and is referred to as evolution. The most renowned feature of evolution is that all species living today are somehow successors of species which existed earlier. In addition, all human beings

Introduction to management enquiry Essay Example | Topics and Well Written Essays - 1000 words

Introduction to management enquiry - Essay Example Although there are no large-scale changes taking place practically. Just three universities are going to charge less than maximum. Many standard universities still feel that teaching undergraduates is not profitable. The other reason universities hesitate to accept that all institutions and degrees are of equal standard, they fear that their credibility may get damaged. Thus one can feel relieved that just few institutions are going to adopt the new system. Bradford University is planning to give scholarship to computer science students, and the number of students would be reduced on the basis of grades. Poorly performing students would have to choose less important courses. The standard universities are still stuck up in managing the cost of teaching undergraduates. Yet the most acceptable way is to use research money and get finances from over seas students. The result is universities are planning to accommodate more foreigners by reducing the number of home students. This implementation of new system would be difficult because of low cap on fees. Expansion of popular courses would also be an option when extra students are taught at lower expenses. Universities should recruit right number of students because drastic increase or decrease would be unprofitable for them. If the university increases the number then it would lose government funding and also it would be fined. Let us see how it goes. The government 's target of bringing 50% of youngsters to universities by 2010 will not be achieved too. The government must have to ignore those universities that are expanding popular courses if the planned number is to be achieved. The implementation of this new system may bring some ridiculous situation to the over all scenario of the whole education system. It may look like chain of super store offering various incentives for their clearance sale or for increasing the revenues. It seems that all these binding conditions will not be successful, it will make universities like half-markets and it would be very difficult to manage. Critique The article paints a very bleak picture of the whole scenario. Although it contains some valid points but still there are some positive aspects of the Education bill 2004. The authority gained by universities for fixing tuition fees up to 3000 would give a much-needed fiscal width to universities. It is true that government funding has dropped but the gap created by this reduction could be fulfilled by the increase in the fee. It is also correct that the gap was financed from research and maintenance funds, but it had slowed down much needed research work. That retarded research will also get a boost from the income gained by the universities by increasing the tuition fee. The writer admits this fact that the students are real beneficiaries and they should pay more, so the academics may also get reasonable ruminations. The fear of rise elitism indicated by writer can be ignored keeping in view other benefits of this new system. Baroness Diana Warwick, chief executive of Universities UK said that the passage of this bill was essential, in her view, for the future health and strength of universities. She
