Principles of Building Structure - Essay Example When the beam has sufficient supported against any form of buckling, a failure of the beam is experienced. This results in the generation of the maximum material yield at one point of the maximum moment (Brett 1989). Hence, the applied loads have the potential of ensuring that the beam reaches its plastic moment capacity. This beam is regarded as laterally supported beam and the yield stress governs the design strength. When beams bend on a major axis, they tend to develop a stronger stiffness and strength. Thus, such beams become vulnerable to failure that results from lateral torsional buckling before they acquire their in-plane capacity of the plastic moment, which will brace them against lateral twisting and deflection. These types of beams are regarded as laterally supported beams. Beams bending strength design is governed by yielding and supported against buckling. A laterally braced section of a beam has a bending strength, which is the plastic moment Mp. Inelastic deformation is expected at the service load when the shape factor of the beam is large. However, for shape factors that exceed 1.5, 1.5My limit is applied at the factor load in order to control the inelastic deformation of the various sections of the beam. Such a provision is not expected to limit the plastic moment for the hybrid section when the yield stress is considered to be less than the expected flange yield stress. However, web yielding is not associated with any significant inelastic deformations. When the inertia moment about the axis of bending is less or equal to the out of plane inertia moment, lateral-torsional buckling never develops. Therefore, for shapes, which are bent within the minor axis and those that have lz = ly, lateral-torsional buckling limit state does not apply. Such shapes include circles and squares. Lateral buckling of a beam does not occur when the compression of the flange is adequate and the flexural

Management is an art Essay Example | Topics and Well Written Essays - 3000 words

Management is an art - Essay Example Any company was considered as a machine, the managers were the operators and the workers, merely pawns. Today management has a whole new concept (McCrimmon, n.p. 2007). Suppose a manufacturing firm hires me as a manager. The workers over there used to make 6 units in an hour. After they hired me, I trained them, taught them some new techniques and now they make 8 units per hour. This efficiency in the workers reflects the efficiency of the manager. If the manager is incompetent then the efficiency of the workers does not change, rather in some cases it goes down. Managers take responsibility of what they do. They are creative and analyzing. Managers discover what is unique about a person and then use his unique quality to achieve their goals. The job of a manager is to achieve performance using a person's talent (Buckingham, n.p. 2005). In order to understand how managers work, let us first understand how many levels of managers are there in an organization. Let us take the example of a manufacturing company. In this company there are three levels of management as shown in Fig 1, Appendix A. The top most level is where the President, the Vice President or the CEO is present. These managers have the greatest responsibility because they are sitting on top of the organization. These people set the goals and objectives of the company. As their work is so important therefore they have to have extensive knowledge of management roles and skills. Their decisions are long term; therefore they are responsible for the company's strategic policies. Next is the second level of management. The managers here set realistic goals for the first line managers. They drive these goals from the long term plans their top most management has made. Managers of this level have specialized understanding of certain managerial tasks. Their tactical decisions actually come from the strategic decisions of top level management. The last, but not the least is the first level managers. Their decisions are usually short term, but these decisions effect the long term decisions made by the top management. They have direct contact with the workers on the job, hence they are responsible for assigning them work. An office manager, supervisor and Forman, all lie in this category. They do not have much experience in managerial skills, but they do have a lot of technical knowledge. In our case, they have production knowledge; can troubleshoot, but there might come a point where they cannot do anything, and will then go to the middle management for help. 3. LEADERSHIP AND COMMUNICATION Leadership means to influence and motivate others. In an organization it affects the cost, revenue, earnings, share prices, motivation and engagements. Management is a subset of leadership. Effective leadership ensures effectiveness in organization. In an organization a leader sets direction, puts in effort to influence people so that they may follow this direction. This direction if set by the higher management and it goes towards goal attainment. There are four major functions of management. Planning, organizing, leading and

How oil exploitation in Alberta affect local enviorment Essay

How oil exploitation in Alberta affect local enviorment - Essay Example Despite the benefits associated with the exploitation, the process has numerously adverse effects on the environment. To begin with, oil sand exploitation in the area affects the availability of water in the area. The whole process requires large volumes of water for the separation of sand and oil. Therefore, the whole process of extraction brings about a deficiency in water content in Alberta (Alvarez, 2013). The process of exploitation of oil in Alberta is associated with the introduction of harmful gases, as well as metals into the earth’s surface and atmosphere. Naturally occurring carbon dioxide and other harmful emission are exposed to the atmosphere during the exploitation. In addition, the exploitation process leads to the concentration of heavy metals such as nickel, mercury, copper and zinc, among many others in the area (Dusseault, 2002). Admittedly, the exploitation process is associated with deforestation. Normally, trees in the area are cleared before exploitation starts. In addition, the overburden top soil is removed from the area of exploitation so as to increase the accessibility of the oil sand. This whole process has a general effect of soil erosion in the area. The exploitation of oil in Alberta also affects aquatic life. Research revealed that there exist a relationship between deformity of fish embryos and their exposure to oil sands. Therefore, as much as the exploitation process takes root, the aquatic life in the area is exposed to the oil sands, thus affected (Dusseault, 2002). A research done in 2007 showed that wildlife and human beings had generally been affected by the exposure to the oil sands. For example, research done on moose revealed that the organisms had as much as 454 times the acceptable levels of arsenic in their body systems due to the exploitation process. Moreover, there have been great concerns about

Art - Essay Example Reproductions of his work appear on posters, calendars, mouse pads, and other widespread consumer items. Even those works not immediately known today are quickly recognized by his unique style and approach, such as his painting Wheatfield with Cypress. Wheatfield with Cypress is an example of Van Gogh’s work while he was a resident at Saint-Remy hospital for the mentally unstable. It is a member of a series of paintings in which Van Gogh explored an image or a theme. Whether it was this painting or another one of the series, he wrote to Theo that the trees â€Å"are always occupying my thoughts, I should like to make something of them like the canvases of the sunflowers, because it astonishes me that they have not yet been done as I see them. The tree is as beautiful of line and proportion as an Egyptian obelisk. And the green has a quality of such distinction. It is a splash of black in a sunny landscape, but it is one of the most interesting black notes, and the most difficult to hit off exactly that I can imagine† (cited in Wallace, 1969: 144). His fascination with the trees themselves as well as their contribution to the landscape overall is evident within this painting. The image depicts an initially confusing scene. The brightly lit landscape is covered by a swirling mass of clouds in a sky that seems eternally blue. The scene depicts a golden wheatfield not far from the hospital in which Van Gogh stayed in southern France (Wallace, 1969). The field is interrupted by a set of wind-swept green bushes in its center to provide balance and a pair of flame-like cypresses standing proudly to one side. This is backed by small green foothills and then blue-tinged mountains rising to back the cypress trees. In the extreme foreground, a glimpse is given of a spring-green field filled with wild flowers in the bottom right corner. Another vividly green bushy area surrounds the two cypress trees, providing a solid base to the narrow

Rights of the Child and the Childcare Essay Example | Topics and Well Written Essays - 1000 words

Rights of the Child and the Childcare - Essay Example Being young human beings, children cannot and are not allowed to acquire certain rights that adult humans enjoy. Due to their premature and underdeveloped intellectual, emotional, social, and spiritual faculties, they are not permitted by laws to vote, to marry, to engage in sex, etc. that only fully developed humans are able to responsibly do. It is because of children's limited power that critics question the capacity of children to have rights. Advocates of the will and interest theory of rights argue that a right is protected choices that only those who are capable of exercising can enjoy (Archard). But, in response to will theorists, it is also due to children's limited power that spurred the need to give them a set of special set of rights distinguished from adults. The Universal Declaration of Human Rights proclaims that 'childhood is entitled to special care and assistance (Article 25).' This has entitled them to enjoy a new set of rights that the government of UN member countries should uphold and protect. This is what the United Nations Convention on the Rights of the Child contains. One of the primary violations of children's rights is child abuse. ... Children suffering from these may experience serious negative effects that would largely impair the growth of an abused child. Low self-esteem, depression and anxiety, injury, criminal and anti-social behavior, delinquency, or even death could from these. Protecting children from impaired development of their faculties provides them the need for a different set of rights that adults should respect.  

American Civil War Essay Example for Free

American Civil War Essay From the start of the Civil War until the end of the Reconstruction period, America faced what can be considered a revolution. During this time, many social and constitutional developments emerged and brought great change to the country. Social developments that contributed to the revolution were the Freedmen’s Bureau, the Ku Klux Klan, and the Black Codes. Constitutional events that sparked dispute were the three civil rights bills, the Emancipation Proclamation, and the reconstruction. Between 1860 and 1877, both constitutional and social developments merged to created drastic changes that threatened the balance of life in the United States, causing revolt throughout many Americans and bringing about reform to the nation. Before 1860, the United States was split into two sides fighting for power: the North and South. Slave states and free states were constantly competing for representation in Congress. In order to reduce conflict, the Missouri Compromise and the Compromise of 1850 were passed. Tensions lowered to a degree, but the compromises only delayed the inevitable discord. State’s rights was a critical topic during this time period. The south believed that they had the constitutional right to secede. After Lincoln was inaugurated in 1860, seven states seceded from the Union. Four more states followed after that. South Carolina, in particular, felt their rights had been stripped off of them, and challenged the Constitution of the United States. Document A) South Carolina feared the north would gain enough power that they would abolish slavery in the south, crippling their slave-based economy. This sequence of events induced the bloody Civil War, later leading to the enactment of the Emancipation Proclamation, which meant the freeing of slaves that were still under possession in 1863. Eventually, the 13th amendment, which abolished slavery, was passed. The end of the Civil War meant the end of bloodshed but the start of reconstruction of the nation. Although slaves were finally freed, it was still rough life for the freedmen. Some blacks felt betrayed by their own government. They were baffled at the fact that they fought for their nation but could not vote for their representatives. In the petition to the Union convention of Tennessee, it is stated that blacks were treated unfairly in court, as the courts would not even receive â€Å"negro testimony. † (Document C) Gideon Welles, Lincoln’s Secretary of the Navy wrote in a diary that the Federal Government has no control of whether or not blacks can vote; he felt it was up to the states to decide. Document D) In attempts to unite the nation, several acts were put into effect. The Freedmen’s Bureau, for example, was set up to help blacks read and write in order to counteract their disadvantages in education. It also provided food shelter, welfare, and medical attention to those affected by the war. Unfortunately, some acts were not in favor of the blacks, such as the Black Codes. The Black Codes prohibited blacks from renting land or e ven borrowing money to buy land. It also forced them to sign working contracts, synonymous to slavery. President Johnson felt that the Black Codes were necessary because he did not want America becoming â€Å"Africanized. † In a petition to the commissioner of the Freedmen’s Bureau, some African Americans felt their promised rights were being neglected. (Document E) On the other hand, political actions were taking place in the struggle for equal rights for all Americans. Republicans were taking control of government and were also ignoring the orders of President Johnson. Radical Republicans were struggling for equal rights throughout nation. In 1866, the Civil Rights Act was created. This act stated that African Americans were United States citizens, shielding them from the Black Codes, and essentially overriding the Dred Scott decision. Shortly after came the Civil Rights Act of 1866. The changing of the Constitution to include the 14th amendment was considered revolutionary. (Document F) President Johnson was impeached in 1868 due to 11 crimes and misdemeanors. He was the first president in history to get impeached. After his impeachment, blacks now started to receive more equal treatment. Blacks were finally able to vote in the 1868 election, which ended up giving the Republicans a victory. (Document G) The 15th amendment was also added to the Constitution, prohibiting any state from denying a citizen the right to vote. Although revolution was going positively throughout, the creation of the Ku Klux Klan was a negative addition. Their goal was to terrorize and scare blacks by force. (Document I) In 1870, Congress decided to ban these secret organizations and enforce the 14th and 15th amendments through the Force Acts. Document H) All in all, between 1860 and 1877, both constitutional and social developments caused great reform in America. Revolutionary ideas such as the freedom of slaves, anti-secession, and rebellion played a key factor throughout these years. The once estranged country was back on track as a unified whole. African Americans, as a result of constant struggle, gained their rights and freedom. It is safe to say that the United States faced a period of reconstruction, which amounted to the shaping of the country.
