Causes of Failures of Construction Essay Example | Topics and Well Written Essays - 2250 words
Causes of Failures of Construction - Essay Example As the paper discussesà the difference between procedural failures and technical failures is that the former happen because of human errors while the latter occur because of physical proximate causes. In a vast majority of cases, technical failures are an outcome of the procedural failures. Procedural failures include but are not limited to the problems of communication between the parties involved in the project, and lack of resources. On the other hand, technical failures include such circumstances as settlement of the structure because of inadequate soil compaction.à This paper discusses the administrative causes of failure in the construction projects. Administrative causes of failure of a construction project are fundamentally controlled by the project management. Managementââ¬â¢s ability to cope with both the internal and external factors of risk for a certain construction project plays a decisive role in determining the success of a project. Causes of failure of construction projects discussed in this paper include human and organizational aspects and change management with referral to certain case studies.à Canyon Views Project is a project of construction of villas in DHA Phase II Extension, Islamabad, Pakistan. Bridgestone Construction Company has served as the general contractor on this project.à One reason for the delay of accomplishment of milestones is the frequency of change of project managers of the general contractor.à ... Managementââ¬â¢s ability to cope with both the internal and external factors of risk for a certain construction project plays a decisive role in determining the success of a project. Causes of failure of construction projects discussed in this paper include human and organizational aspects and change management with referral to certain case studies. Case Study: Canyon Views Project Canyon Views Project is a project of construction of villas in DHA Phase II Extension, Islamabad, Pakistan. Bridgestone Construction Company has served as the general contractor on this project. Although the project is in progress and cannot be considered as a failure altogether, yet the individual milestones in the way of execution of the project were not timely accomplished due to which the customers of villas had to wait for considerable time to enter their villas after making the payment. One reason for the delay of accomplishment of milestones is the frequency of change of project managers of the g eneral contractor. Bridgestone Construction Company saw many changes of project manager. Within just the first two years of the start of projectââ¬â¢s execution, at least three project managers had been changed. Some left the company on their own after working in it for some while while the others were terminated b the general manager (GM). The reason project managers could not stay for long on the project was not quite hidden from the workforce. The GM had had so much influence and control on the project, that he would not let the project managers exercise their rights as a project manager on the construction site. Any decision taken by the project managers seeked approval of GM before

Hepatitis C Research Paper Example | Topics and Well Written Essays - 1250 words
Hepatitis C - Research Paper Example Transplantation of organs from infected people also spreads the hepatitis C virus. But in 1992 the health professional formulated a blood donation test which detects the presence of hepatitis C virus. After 1992 the blood of donor is tested for the hepatitis C virus before transfusion of blood or transplanting organs due to which the chance of transmission of hepatitis C virus is lowest nowadays. Hepatitis C virus is also transmitted by sexual contact with an infected partner or one having many sex partners. Transmission of virus also occurs from infected mother to baby during birth but the ratio of transmission by this way is low (Centers for Disease Control and Prevention). Anatomy: The liver is one of the main organs of digestive system which is reddish brown in color. Liver is the largest gland of the body which produces different hormones. Liver is divided into two lobes right and left lobe on the anterior and posterior surface. On the inferior surface the liver has two small lo bes quadrate lobe and caudate lobe between the right lobe and the left lobe. In between the caudate lobe and the quadrate lobe is porta hepatis which receives hepatic portal vein, hepatic artery proper and common bile duct. Liver receives blood by two blood vessels hepatic artery and portal vein. The parenchyma of liver is made up of epithelial cells called hepatocytes. Blood sinusoids are present in between hepatocytes which are known as hepatic sinusoids. Portal area is a space which contains three tubular structures collectively called portal triad. The portal triad contains a branch of portal vein, a branch of hepatic artery and bile duct. A delicate covering is present around the parenchyma of liver known as Glisonââ¬â¢s capsule. The liver performs different metabolic functions. Liver helps in protein synthesis like albumin which helps in regulating osmotic pressure. Liver synthesize fibrinogen which helps in blood clotting. Liver produces globulin which helps in immunity. I n fat metabolism liver plays important role. It synthesizes cholesterol and also performs lipogenesis. On the other hand liver produces bile which is necessary for the emulsification of fat which is breakdown of fat so liver plays role in synthesis and breakdown of fat. Bile is then transported to gall bladder for storage. From gall bladder the bile goes to the duodenum for fat emulsification when fat reaches the duodenum for digestion. Liver also plays important role in carbohydrate metabolism as gluconeogenesis, glycogenolysis and glycogenesis occur in liver. Liver also stores the extra glucose in form of glycogen. Thrombopoietin is hormone which is also produced in liver. The function of thrombopoietin is the regulation of platelets production in bone marrow. The liver helps in the breakdown of different substance like insulin, hemoglobin, different drugs and ammonia etc. During the first three months of fetal life the liver produces red blood cells. Liver also plays role in bloo d pressure regulation because it produces angiotensin hormone (Robbins et al 2005). Abnormality: By attacking liver cells the hepatitis C virus make morphological changes in the tissues of liver. The hepatitis C virus starts necrosing the liver cells and causes the shrinkage of the liver. The liver becomes wrinkled and red in color. Cross sectional examination of the necrosed liver shows muddy red appearance and blotchy bile staining. There is complete destruction of

The U.S. Military Fighting Forces in World War II (European vs Research Paper
The U.S. Military Fighting Forces in World War II (European vs. Pacific Theaters) - Research Paper Example However, some of the technological differences made the United States more superior than most of their enemies. Furthermore, despite the disunity in the American military forces, the military of such countries as Japan, which was the strongest force in the eastern bloc, also exhibited such severe disunity thus contributing to the American victory. 1) Geographic and Environmental Conditions (i.e., effecting the style of warfare) Climatic condition played important role in earning America the victory in the war, with an effective knowledge of the pacific climate in summer, the American forces prepared adequately with appropriate attire and carried drugs and mosquito nets to cushion the soldiers from the adverse weather in the continental region. The warm and humid climatic condition of the pacific in summer presented several challenges to the Japanese who did not have adequate information of the climatic condition in the pacific region. The humid condition hastened the pace of metallic . The Japanese did not prepare for such radical ramifications and therefore lost most of their artillery as they rusted fast thus proved inefficient. Additionally, more Japanese soldiers died of rom such tropical diseases as malaria, which they had not prepared effectively for. The warm and humid climate in the region required light attire a feature that the American forces had learnt of thus leaving their Japanese counterparts ill dressed for the combat thus the ensuing inconveniences in the battlefields. The jungle environment in the pacific required specific tactic of warfare, the American formed small patrols hat would maneuver through the jungle more efficiently often relying on the efficient backup owing to the efficient communication among the small troops. Additionally, the American soldiers relied on the marines after they learnt that the terrain would not permit large military formations. American and Japanese soldiers would therefore run into each other unannounced in the ir daily patrols thus resulting in open warfare. The military combat with the infantry and artillery type of fighting this implied that fighting was at close range requiring the use of effective weaponry. 2) Type of Enemy (i.e., German's vs. Japanese soldier & tactics used); The American success in the war portrayed that the country invested a lot of resources in understanding their enemies. Information is often key in military since it helps formulate both the offenses and defenses. With the adequate information about the enemy, the American government often employed the best tactics in either attacking or resisting the advances of the enemy. Technological advancement in the war was important in the ending the war. America had to prove technological advancement in order to end the war. The eastern bloc had a renewed determination to foster the war but their evident technological inferiority influenced their decision to stop fighting. The nuclear bombing of Hiroshima and Nagasaki pr oved to the eastern forces that the United States had the best military technology and could annihilate their population thus influencing their decision to end the spirited fight. The Germans also proved greater

The Main Features and Problems Faced by Service organisations In Essay
The Main Features and Problems Faced by Service organisations In pursuing this Technique(Banks in the UK) - Essay Example More than 74% of the United States work force for example is employed on this sector (Li H. & Smith L.2001).With a dramatic fall in labour cost, the cost of processing information, overheads has become far more important in the present age of advanced manufacturing technology (AMT) with direct labour representing 5%. Thus, it therefore now appears difficult to justify the use of direct labour or direct material as the basis for absorbing overheads.ABC was developed to overcome some of the major problems of the traditional cost accounting. The 80s witnessed an influx of research in to this concept. Activity based costing involves the identification of the factors which cause the costs of an organisations major activities (Lewis; J.R., 1993). In this regard overhead are charged on the basis of their usage of factor causing the overhead. In the UK and the US, information and manufacturing technology are widely used in both manufacturing and the service sector, with both sectors experiencing different degree of the usage (Palmer, A.2000). The four main characteristics inherent to services provide an answer to the main problem of ABC in the service industry. ... There is a strong possibility that the same enquiry would be answered slightly differently by different people. 1.2 Activity based costing and the service industry in the UK (Banking Sector). By the end of the 1980s, ABC became the focal point within the realms of academic researchers, consultants and managers as a means of overcoming the disadvantages of traditional cost allocation methods. Cost accounting was limited to it s usage of one volume sensitive driver (Cooper & Kaplan 1991). By 1990 initial followers of ABC in the manufacturing sector were able to reduce cost, identify opportunities for improvement and determine a more profitable product mix (Cooper & Kaplan 1991). Thus, the concept gradually gain grounds and became popular in the manufacturing sector. In the service sector, the adoption of ABC has been relatively slow, and the concept was rarely used apart from the health and banking sector. A recent study however, by Schultz & Rostocki (2004) concluded that, the rate of adoption of ABC in service and manufacturing industry was now similar. An essential part of managing and ensuring the long term competitiveness of banking institutions in the United Kingdom will be to configure, manage the service deliveries and their chain of distribution processes. The financial sector in the UK, like in any other country is characterised with the following characteristic Banking institutions and other financial houses are price takers. This is so because the prevailing market price has to be accepted. Large number of institutions offering the same services with none of these institutions being able to influence price. However, their actions are not negligible. As a move by institution A will trigger a whole chain of event, in the form of competitive service

Obligations Essay Example | Topics and Well Written Essays - 1500 words
Obligations - Essay Example The specific performance of the task by the offerree is the objective indicating that the offerree has agreed to the terms of offer and acceptance. Therefore, it flows that there are three aspects to it, firstly, there is a valid offer flowing from the offeror to the offerree, secondly, the offeree accepts the offer by promise or conduct and thirdly, the object of consideration is fulfilled by the offerree. Therefore it could be logically analysed that the offer is an expression of willingness to contract on certain terms and the intention of the offerree, upon specific performance, becomes binding as soon as it is accepted by the person to whom it is intended. (Offer). In the above case, Aishah fulfilled the terms of the offer made by her father, Hasan, by attending all her seminars and also by graduating with a first class degree. By conduct she has accepted and fulfilled all the terms of the agreement. Thus her father is bound to pay her à £1000 and also give her a car as promised to her through a valid offer. This could be enforced by Aishah on her father, Hasan. There are several rules which govern offer and acceptance. In the first place, the communication of acceptance has to be communicated to the offeror by the offeree, or by any other person. Again, in case of non-acceptance, the fact should also be communicated to the offeror. In the leading case, Felthouse v.Bindley (1862) 142 ER 1037, it was held that silence was not tantamount to acceptance. The details of this case were that an uncle wrote to his nephew expressing his intentions to buy one of his horses. He wrote if he did not hear from the nephew, he would consider the horse as his (uncle) own. The nephew did not reply. The uncle though he had established ownership over the horse by implicit acceptance. However, later, the horse was sold through auction. The uncle sued the auctioneers, on the grounds that

Protein Concentration Lab Report Example | Topics and Well Written Essays - 1000 words
Protein Concentration - Lab Report Example The two most common examples are -helix and -sheet (fig. 1) Proteins are not completely rigid systems and they shift between several related structures while they perform their biological functions or roles. Such changes are often induced by the binding of a substrate to the protein's active site. The Biuret reagent is composed of potassium hydroxide (KOH), copper (II) sulphate (CuSO4) and potassium sodium tartrate (KNaC4H4O64H2O). This reagent is used in a protein assay, a colorimetric test to determine protein concentration by detecting the Cu2+ ion with the help of spectrometric methods. In the presence of proteins, this blue reagent turns purple, while when there are short-chain polypeptides in solution it turns pink [MadSci Network]. A spectrometer is an optical instrument used to measure properties of light (intensity, polarisation, etc) over a specific range of the electromagnetic spectrum (in this experiment UV-Vis at a 560nm). The independent variable is generally the wavelength of the light expressed as nanometers. These instruments are used in spectroscopy to measure the interaction between radiation and matter. In this experiment, UV/Vis spectroscopy is used to determine the concentration of a solution of proteins with the aforementioned Biuret agent. The Beer-Lambert law (A=lc, where A is the absorbance, is the absorption coefficient, l is the distance light travels through the material, c is the concentration of the species that absorbs the light) establishes that the absorbance of any solution is directly proportional to the concentration of the solution [Sheffield Hallam University]. To establish the concentration of a solution, it is necessary to know first how the absorbance changes with the concentration. In order to achieve this, the calibration curve must be determined. AIMS Protein solutions are colourless so cannot be easily determined by simple colorimetric methods. Biuret reagent (copper sulphate, sodium hydroxide, and sodium potassium tartrate) reacts with compounds containing two or more peptide bonds to give a purple-violet colour, so this reaction can be used for a colorimetric method for estimating the concentration of protein in solution. This experiment involves treating a series of proteins of known concentration with Biuret reagent. The data obtained may be used to draw a standard curve. This curve can then be used to estimate the concentration of 2 protein solutions for which the concentrations are not known. METHODS You have been provided with: (a) protein standard solution (albumin) 10 mg/ml (b) albumin solutions X and Y of unknown concentration (c) Biuret reagent (d) de-ionised water Prepare the following in labelled test tubes, mix well and leave for 20-30 minutes at room temperature: Tube A B C D E F G Protein standard (ml) 4 3 2 1 0 - - De-ionised water (ml) 0 1 2 3 4 - - Unknown albumin X (ml) - - - - - 4 - Unknown albumin Y (ml) - - - - - - 4 Biuret reagent (ml) 6 6 6 6 6 6 6 Read the absorbance at 540nm for solutions A - G (first using tube E as the blank to zero the

Money and Banking - Essay Example To put into effect the ruling, federal authoritarian agencies inspect banking association designed for CRA compliance, in addition to get this information into deliberation when appreciative applications for fresh bank branches otherwise intended for mergers or acquisitions. The Worker-Community Reinvestment Act of 1977 looks for to address inequity in loans prepared to persons and businesses as of less and reasonable -income neighborhoods. The Proceed mandates that the entire banking organization that take delivery of FDIC insurance be assess to ascertain if the organization is suggest credit in cooperation in which the banks receive deposits, in a mode consistent by means of safe and sound process. The regulation does not file exact criteria for assess the performance of economic institutions. To a certain extent, it through that the assessment process must provide accommodation the circumstances and context of every one particularized institution.
