Piping

Introduction: The term fabrication applies to the cutting, bending, forming, and welding of Individual pipe components to each other and their subsequent heat treatment and nondestructive examination (N DE) to form a unit (piping subassembly) for installation. The term installation refers to the physical placement of piping subassembly, valves, and other specialty items in their required final location relative to pumps, heat exchangers, turbines, boilers, and other equipment; assembly thereto by welding or mechanical methods; final NEED; heat treatment; leak testing; ND cleaning and flushing of the completed Installation.Depending on the economics of the particular situation, fabrication may be accomplished in a commercial pipe fabrication shop, or a site fabrication shop, where portions of the piping system are fabricated into subassembly or modules for transfer to the location of the final installation. As a general rule piping NAPS 21/2 (DNA 65) and larger for nuclear and fossil power plants, chemical plants, refineries, industrial plants, resource recovery, and generation units are most often shop fabricated.Piping NAPS 2 (DNA 50) and smaller Is often shop fabricated where special heat treatment or cleaning practices may be required: otherwise it is field fabricated. Pipelines and other systems involving long runs of essentially straight pipe sections welded together is usually field assembled. In recent years, the infusion of new bending technologies, new welding processes, new alloys, fracture toughness limitations, and mandatory quality assurance (QUA) programs have made piping fabrication and Installation much more complex than In the past.Greater emphasis Is being placed on written procedures for QUA and quality intro (ICQ) programs, special processes, and qualification and certification of procedures and personnel. Improper selection of fabrication or installation practices can result in a system, which will not function properly or will fail before its expected life span. Accordingly, fabrication and installation contractors must work closely with the designer and be aware of the mandatory requirements of the applicable codes, the unique requirements and limitations of the materials, and those of the fabrication and installation techniques being applied.Codes and Standards Considerations: A great many codes and standards apply to piping. It is incumbent on the fabricator and/or Installer to be familiar with the details of these codes and standards since some codes have the force of law, As an example, the SAME 331. 1 Power Piping Coded is referenced by SAME Section I Power Boilers: for piping classed as Boiler External Piping. The latter that is law in most states, contains rules for code stamping, data reports, and third-party inspection. Piping under SAME Section 1113 also has legal standing. Most other piping codes are used for contractual agreements.Most codes preference SAME Section for nondestructive examination methodol ogy and SAME Section XIX for welding requirements. Each of the codes covers a deferent piping practices, some have mandatory requirements, while others only have recommendations. Heat treatment requirements may vary from one to another. The manner in which the code-writing bodies have perceived the hazardous nature of different applications has led to differing NEED requirements. Generally, the codes are reasonably similar, but the owner, designer, fabricator, and installer must meet the specifics of the applicable code to ensure a satisfactory installation.It is essential that the designer be very familiar with the code being used and that purchasing specifications for material, fabrication, and installation be very specific. Reference to the code alone is not sufficient. In the design, a particular allowable stress for a specific material, grade, type, product form, and/or heat-treated condition was selected. The specifications issued for material purchase and fabrication must ref lect these specify to assure that the proper materials and fabrication practices are used. It is also incumbent upon the fabricator and/or installer to be very familiar with the applicable code.Each project should be reviewed in detail. â€Å"Standard shop practices† may not always produce the desired result. Communication between the designer, fabricator, and installer is essential. All should be familiar with the various standards used in piping design. Most piping systems are composed of items, which conform to some dimensional standards such as SAME 836. MM and SAME 836. MM for Pipe, 816. 57 for flanges, etc. The Manufacturers Standardization Society (MS) and the American Petroleum Institute (API) issue other dimensional standards.The Pipe Fabrication Institute (IF) publishes a series of Engineering Standards, which outline suggested practices for various fabrication processes. These standards give excellent guidance for many aspects of piping fabrication not covered by t he codes. The American Welding Society (SAWS) publishes a number of recommended practices for welding of pipe in various materials. Materials Considerations: Piping systems are fabricated from a great variety of metals and nonmetals, material selection being a function of the environment and service conditions. Materials must inform to the standards and specifications outlined in the governing code.Some codes such as SAME Section Ill impose additional requirements on materials beyond those in the material specifications. All fabrication and installation practices applied to these materials must be conducted so as to assure that the final installation exhibits all of the properties implicit in the design. For example, hot bending of certain austenite stainless steels in the assassination range will reduce their corrosion resistance if they are not subsequently heat-treated. Accordingly, a heat treatment to restore these properties should be specified.

Huckleberry Finn Essay

Fathers are an important aspect of every person’s life and have a great influence their children. In The Adventures of Huckleberry Finn, a novel by Mark Twain, Huck in a way has two fathers. While Pap Finn is Huck’s real father, Jim also becomes a father figure to Huck because Jim is Pap’s foil. He becomes what Pap is unable to be by protecting him and teaching him right from wrong. While Pap Finn and Jim both become fathers to Huck, they influence Huck in many different ways. Pap lets Huck get away with bad habits and Huck had even stopped cursing, but now he â€Å"took to it again because pap hadn’t no objections† (34). When Pap first finds out Huck goes to school, he says, â€Å"you drop that school you hear? I’ll learn people to bring up a boy to put on airs over his own father and let on to be better’n what he is† (29). Pap thwarts Huck from getting ahead in life, just because he can’t read or write himself. Pap also wastes much of his life and money on alcohol. When Pap hears that Huck has six thousand dollars, he immediately finds Huck to get it from him. When Pap threatens to beat Huck, he â€Å"borrowed three dollars from Judge Thatcher, and pap took it and got drunk† (31). He also teaches Huck things like stealing, and says to â€Å"take a chicken when you have a chance† and that it isn’t â€Å"no harm to borrow things, if you was meaning to pay them back, sometime† (76). Jim however is very genuine and honest. When Huck and Jim separate from each other in the fog, Jim becomes terrified, but when he finds Huck next to him safe he is very happy and grateful. However when Huck starts to play a trick on him saying he was there the whole time he says â€Å"trash is what people is dat puts dirt on de head er dey fren’s en makes? em ashamed† (98). Huck then feels very guilty and apologizes. Jim teaches him right from wrong, and Huck knows now not to hurt people’s feelings. Jim, unlike Pap, values his family as well. Jim is always â€Å"thinking about his wife and his children? and he was low and homesick†, which teaches Huck that black people and white people aren’t very different, and that Jim â€Å"cared just as much for his people as white folks does for their’n† (167). Huck also has a choice of giving Jim up to his rightful owner or helping him escape slavery. Huck finally decides that he’ll â€Å"go to hell† if that is what it takes to save Jim. Because of what he has learned from Jim he disregards what society has taught him and follows his gut to save Jim (227). Because Pap and Jim are so unlike, they teach Huck many different things and have a great impact on him. Pap and Jim treat Huck very differently as well. Pap constantly abuses Huck, and beats him for no reason, and â€Å"by-and-by pap got too handy with his hick’ry† and Huck had welts all over (34). Even when Pap finds a picture that Huck got for doing well in school he tears it up and says, â€Å"I’ll give you something better-I’ll give you a cowhide† (29). Jim however protects Huck. When Huck and Jim are floating along the river, they come across a house. Huck’s father was dead in the house, but Jim finds Pap first and covers him up and tells Huck to â€Å"come in? but doan’ look at his face-it’s too gashly†, without telling Huck who the dead man was (60). Jim wanted to protect Huck from seeing his father dead, despite how Pap treated Huck. Jim is also very grateful of Huck. Jim reminds Huck many times that he is â€Å"de on’y white genlman dat kep’ his promise†, and that Huck is his best and only friend (102). Pap Finn and Jim both affect Huck differently because of the way they treat him. In The Adventures of Huckleberry Finn, by Mark Twain, both Pap and Jim can be seen as Huck’s fathers. Because they are so different, they have very different influences on Huck by teaching him different things and by the way they treat him.

EU LAW Term Paper Example | Topics and Well Written Essays - 1500 words

EU LAW - Term Paper Example This implies that there was the evolution of certain relevant legal principles from a national level to conform with European Union laws and systems. The potential conflict led to the creation of the General Principles of European Union Law. The General Principles created a framework through which the new legal instruments of the common market could be streamlined and applied in all national jurisdictions (Tridimas, 2006). The General Principles include a set of concepts that guide the courts in the enforcement of European Union Laws (Schwarze, 2006). They are invoked to ensure that the potential tensions between EU law and local laws are minimized. More importantly, they are applied to ensure that the spirit of the European Union law is honoured in cases. They main concepts in the General Principles of EU Law include fundamental right, proportionality, certainty, equality and subsidiarity (Foster, 2011). Individuals can therefore request for review of their cases on the bases of these principles when they feel it is not fully honoured. Article 5 (3) of the EC Treaty states that â€Å"Any action by the Community shall not go beyond what is necessary to achieve the objectives of this treaty†. This implies that the interpretation of EU law should not be done such a way that people will incur disproportionate hardships. In R V Intervention Board ex parte Man (Sugar) Ltd1, a company was to incur over a million dollars in fines because their application for a permit delayed by a few hours. It was held that the fine could not be imposed on the company because of this principle. The European Union honours the principles of liberty, democracy, respect for human rights, fundamental freedoms and the rule of law amongst Member States (Article 6). This means that the fundamental rights of individuals must be respected in every case. Courts must be sensitive to the rights of humans in cases that are brought

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

Business Service Operations - Essay Example The assignment also portrays the layout of services and service delivery network of Tesco. Furthermore, it also illustrates certain important suggestions for developing the service concept and the delivery system of the organisation. Services can generally appear on the basis of different shapes and forms. For instance, in business to consumer organisation, service can arrive in the form of retail services. Moreover, in business to business organisation, services can arrive from consulting services and in non-profit organisations, services can arrive from charity services. Any kind of service can produce additional value for the customer’s at large (Berry, 1995). With this concern, the assignment is based on understanding the service concept of an UK based supermarket retailer named Tesco and recommending effective strategies to develop its various services. Service is fundamentally considered to be an activity or set of procedures that is used for maintaining smooth interrelation with the customers and enhancing the overall business performance. Service concept is a vital method of apprehending the nature of services so that the customers comprehend about what they are receiving and employees also understand about what they are delivering. It is a shared understanding of nature of service which encapsulates information about classifying thoughts, customers’ experience and service outcomes. Service concept is a core task in managing different service operations. It can be used as a central tool in the design, distribution and improvement of services of a particular organisation. Service concept concentrates on a particular market segment and provides limited range of services for both customers and business operations (Fitzsimmons & Fitzsimmons, 2000). In order to be effective, service concept must deliver adequate information in order to make

The effect of dystrophin on neuron development in the Central Nervous Essay

The effect of dystrophin on neuron development in the Central Nervous System - Essay Example The DMD is the human gene responsible for providing instructions for making dystrophin. Dystrophin is located in muscles such as cardiac muscles (heart) and skeletal muscles (movement). Small amounts of this hormone are present in the brain specifically in the nerve cells. In cardiac and skeletal muscles, this protein hormone is part of a protein complex which work together to protect and strengthen muscle fibers from injury during contraction and relaxation of the muscles (Hart 23). Dystrophin complex often act as an anchor for connecting each framework of the cells of the muscle with protein lattice and other extracellular matrix. Dystrophin may also play an important role in cell signaling through interacting with proteins which receive and send chemical signals. Little is known so far concerning the functions of dystrophin complex in nerve cells (Hart 24). Some studies have suggested that it plays an important role in the normal functioning of synapses and structure, which are sp ecialized connections existing between nerve cells where the occurrence of cell-cell occurs. In this paper, the focus of ascertaining the effect of dystrophin on neuron development in the Central Nervous System According to Shan and Lihsia (13) dystrophin protein plays an integral role in maintaining muscle membrane integrity. Shan and Lihsia showed that accompanying neuropsychiatric disorder and cognitive impairment often presented in most of the DMD proteins suggests that dystrophin plays an integral role in membrane-cytoskeleton function. The study involved growing c.elegans strains on the nematode growth medium plate at 21 degrees Celsius. Transgenic animals were then generated basing mello et al (1991) standard procedure. In order to generate Punc-119::dys-1 (pLC587), the researchers pieced together the 9.0-kb dys-1 genomic sequence obtained from WRM0611bE10 at an exon 30 with the untranslasted region of cDNA and 169-bp dys-1 3 and 3.9-kb dys-1 cDNA, and subcloned was joined in to the pBluescript II KS vector existing between NotI and XmaI. The researchers then crossed evIs78 (Punc-129::gfp and oxIs12 (unc-47::gfp integrated transgenes into the available respective strains with a view to visulize cholinergic neurons, and GABA. Synchronized the young adult animals of such strains and the synchronized dys-1 larvae for different stages were all mounted on the 2percent agarose pads and then scored for neuronal displacement with a 40? 1.3 NA Neofluar. This was done with an aim of using the microscope with the captured image, which was captured in a camera, along with the imaging software. Shan and Lihsia findings showed that DYS-1/dystrophin helps in regulating locomotion and muscle integrity. The findings of this study, also show that SAX-7 and STN-2/Y-syntrophin functions to maintain the neural integrity in c.elegans. In yet another study Hart Lidov, Timothy Byers, Simon Watkins, and Louis Kunkel (7) scientific study, this researchers came up with antibody (a nti 6-10), which was somewhat more sensitive that the immunolabel dystrophin which were previously available. The researhers then used this anti 6-10 antibody in to investgate whether the asoociation between systrophin and the nervous system. The findings of this study revealed that in the mouse, dystrophin is more abundant in the neurons of the cerebral cortices and the cerebral. This study also revealed that

Discuss The Controversy Surrounding The Chapman Brothers Rectified Essay

Discuss The Controversy Surrounding The Chapman Brothers Rectified Works of Francisco Goyas Disasters of War Series - Essay Example The best in Goya came during the period of war in Spain and this shows that wars really bring out the best in men. The controversy that surrounded the rectification of his work by the Goya Brothers was borne out of the love that this critics had for this great artist and his art work. The Chapman brothers have been accused of defacing the etchings they purchased from Goya’s Disasters of War as the Chapman Brothers’ Insult to Injury had some funny faces that made their collections controversial in nature. The Brothers have been accused of intentionally defacing the appearance of Goya’s Disasters of War and some have even said that they used their Insult to Injury to mock Goya’s works. Although the Chapman Brothers have claimed that Francisco Goya was their model, the fact however remains that the rectification of his Disasters of War actually disproves this notion if one considers the fact that they tried to transform the work of their so called ‘mode l’ in order to produce their own work that is different from his work in several ways (Chapman). The Chapman Brothers succeeded in transforming Goya’s work into sheer pornographic Surrealism but it should be underscored that Goya was more into Romanticism. The issue that has been raised by the critics is that the Chapman Brothers bought a set of 83 etchings from Goya’s Disasters of War and vandalised it. The critics have claimed that the Chapman Brothers were aware that this great art work by Goya is one of the most venerated series of prints in existence (Mey, 2007, p.1). The Chapman Brothers have not only made attempts to erase the memories of the artists from the hearts of men, but they have also destroyed and obscured a great artwork, thus attracting lots of controversies to themselves and their rectified art work. Controversy based on Semiotics The Chapman Brothers unscrupulously rectified the works of Francisco Goya’s Disaster of War Series, which G oya himself used to represent the horrors of the war between 1810 and 1820. In the original work of Goya, he used symbols of humans as an allegory to the sufferings of humans during the war and to express his dissatisfaction and horror at the disgusting lunacy of war. In rectifying the works of Francisco Goya’s Disaster of War Series, the Chapman Brothers used cartoon images to represent the sufferings of humans that Goya was trying to depict through his images and the fact that Chapman derailed from the original message of Goya made people to criticize the revised works of the Chapman Brothers. â€Å"Typical in their broad-brush detestation of Enlightenment tradition are Jake and Dinos Chapman, postmodern artists most famous for ‘Insult to Injury’, their vandalized or ‘rectified’ appropriation of Goya’s Disaster of War prints, in which they pasted fiendish clown and puppy heads over every victim’s grimace....† (Broderick, 2005, p.9). The controversy that surrounded the works of the Chapman Brothers was caused by the cartoon images that they superimposed in their work as they used the symbols of puppies or clowns as figures to represent the human sufferings that Goya intended to show people through his Disaster of War

Poverty, the Never-ending Disease Essay Example for Free

Poverty, the Never-ending Disease Essay Poverty is a lack of goods and services needed to maintain a minimal adequate standard of living. The definition of the term adequate varies, however, with the general standard of living in a society and with public attitudes toward deprivation. No university accepted the definition of basic needs exists because poverty is a relative concept. In poorer countries it means living at the brink of subsistence, while in our country few improvised families confront starvation, although many suffer from undernourishment. Not everyone is born into a life of the rich and glamorous. Those who are fortunate enough know that they are very lucky to be in their position. Others however are totally in different situations. They need to fend for themselves and having meal is something which comes only once a day. Malnutrition is the obvious result of not consuming the right amount of food. This will lead to outbreaks of diseases but in poverty stricken countries there are no hospitals to cure this. Lacking infrastructure means lacking educational rights. People who are living in poverty cannot afford to send their children to school so this will mean an unclear future for their children hence the undernourishment. Furthermore, living in crowded areas, this has a tendency to increase the chances of disease as people are drinking from unsafe sources of water. People around the world are not aware of how immense this issue is and sometimes hesitant to believe the scale that it has risen to. Without understanding the people living at a disadvantage from the rest, there is no cure for the problem. Poverty is not only the problem of the poor, but the rich as well. If the wealthy becomes too concentrated and there are too many people at the low end who cant contribute to the cost of society (taxes t o maintain infrastructure for instance) then more of that burden must fall to the wealthy. The wealthy that derive their wealth by selling goods and services to a mass market will be affected if the market dries up because too many individuals are too poor to be able to buy the goods/services. With hints of the invisible hand playing a role in this, it’s possible that the economy might not adjust to the buyers and sellers. People suffering from poverty may become enraged at the disparity between themselves and the wealthy and may express that rage through a violent revolution and redistribution of wealth. Some wealthy individuals may feel concern about such a disparity and choose to give some of their wealth to better the condition of the poor or to help the poor find a way to prosperity. Poverty in the United States has long been a social, political, and human rights issue. Few people would say that it is not our moral duty, as social human beings to take care of those less fortunate than ourselves, to the best of our ability. These types of people have what is called a â€Å"libertarian†. There is really no specific definition of â€Å"libertarian†, but it is associates justice with liberty. In relation to the matter at hand, specifically poverty in America, libertarians are against taxing the affluent or forcing people to aid the starving and poor. One of the most influential libertarians of our time is Professor Robert Nozik. His theory of justice begins with the principle that all people have rights, which require that we refrain from interfering with others. Other than this we have no obligation to do anything positive for anyone else, and likewise, they have no obligation towards us. These rights are natural or inalienable because all humans have them and they do not come from any social or political institutions. These rights forbid us from interfering with a person’s liberty even if it would promote some general good, or prevent another’s rights from being violated. Overall, the general idea is that people have the liberty to live a life free from intervention of others, and can lead their life however they so choose. In addition, he says that if a person acquired their fortune or possessions without harming, defrauding, or violating the rights of any others, then it is morally permissible to use those things however one wishes. This includes wasting, willing, or endowing the possessions to someone else. Even though many people are dying from starvation and malnutrition, Nozik’s theory of justice states that one has no obligation to help those people. His theory is summarized as follows: 1. A person who acquires a holding in accordance with the principle of justice in acquisition is entitled to that holding. 2. A person who acquires a holding in accordance with the principle of justice in transfer, from someone else entitled to the holding, is entitled to the holding. 3. No one is entitled to a holding except by (repeated) applications of 1 and 2. Relating to poverty, libertarians feel that no matter how the actual distribution of economic holdings may look, if all involved are entitled to the holdings they possess, then the distribution is just. Although Nozik’s theory concentrates on the just of distribution, Rawl’s theory of the difference principle can be thought of as the similar concept. The main moral motivation for the Difference Principle is similar to that for strict equality. The overwhelming economic opinion though is that in the foreseeable future the possibility of earning greater income will bring forth greater productive effort. This will increase the total wealth of the economy and, under the Difference Principle, the wealth of the least advantaged (the poor). The inequalities consistent with the Difference Principle are only permitted so long as they do not compromise the fair value of the political liberties. So, for instance, very large wealth differentials may make it virtually impossible for poor people to be elected to political office or to have their political views represented. These inequalities of wealth, even if they increase the material position of the least advantaged group, may need to be reduced in order for the first principle to be implemented. The difference principle may be the solution to poverty in the near future, but sadly the idea of strict equality between individuals will be a difficult concept for people to grasp. Capitalism is a system designed to produce for private profit, not for public need. We have gotten as far as we have due to decision-making of corporate boardrooms and placing them under the democratic control of the majority that the economy can provide for our needs. To do that, we need to bring into public ownership the largest 500 corporations and financial institutions. If the assets of these giant companies were under our democratic control, then investment and resources could be democratically controlled by working-class people. Resources would be available to address our most pressing social problems and allocated to areas of most need. To achieve this means breaking from giving any support to the two big-business political parties the Republicans and Democrats. They are both fully implicated in creating the present mess we are in. We need to build a new political party to represent our interests as workers, the poor and young people, and which points a finger at the real villains, the super-rich and the capitalist system.

Operational Requirements And Service Conditions Of Piston Engineering Essay

Operational Requirements And Service Conditions Of Piston Engineering Essay ABSTRACT There is an extent in changing the trend of the material by its properties and its characteristic. The majority of the materials completely depend on the application of the material in the component and its versatility. The components by material vary from each other by its properties. The materials have the tendency to change its manufacturing process by its character. A component can be manufactured by using various materials depending according to the application and its life. In this paper we discussed about the manufacturing process of the components like piston, connecting rod and the crank shaft. The alternative methodologies and usage of alternative materials are also explained by using CES chart with its advantages. INTRODUCTION Selecting the appropriate material is an integral part of the successful implementation of an engineers design. A design engineers ability to objectively quantify the combined marketing, technical and manufacturing requirements as they apply to the material selection is critical to the actual as well as the perceived success of the product. This paper contains a deep knowledge about the selection of the material and its manufacturing procedure with justification. CHAPTER 1 GENERAL COMPONENT DETAILS 1.1 PISTON The piston is the most essential component of the engine which actually transfer the energy output from the combustion chamber to the crankshaft through connecting rod. This is a pressure-tight cylindrical plunger which is subjected to the expanding gas pressure. Basically, piston structural components are head, skirt, gudgeon pin, grooves and lands. 1.1.1 OPERATIONAL REQUIREMENTS AND SERVICE CONDITIONS OF PISTON Hence in order to transmit this high power output the piston must be designed lightly and must be robust. The piston must be of higher strength material that can with stand the high pressure that is been generated due to the burning of air-fuel mixture within the cylinder. Piston must be fitted properly to control the expansion due to temperature, without which the piston will fit loosely when in cold and they bind themselves when it gets warmed. 1.1.2 FUNCTIONS OF PISTON Transmit energy from combustion unit to piston pin, Serve as a carrier for the piston ring which seals the compression in the cylinder, Act as a guide for upper end of the connecting rod, Withstand high temperature expansion Despite the heat energy to the coolant. piston.gif Fig(1) Piston Assembly Conditions of piston at normally high speed, Piston moves from the top to bottom of the cylinder and vice versa with a acceleration of speed of around 50mph at midpoint and decelerates. The piston is subjected to pressure of about 6.8MPA. The piston is subjected to temperature of about 315 °C.[1] 1.1.3 DESIRABLE MATERIAL CHARACTERISTICS The Piston materials must meet the following conditions, [2] Low thermal expansions for arresting the hot gases. High thermal conductivity for releasing heat from piston head. High strength to mass ratio (light weight) for transmitting high power output. High fatigue strength for increasing the material strength. Good resistance to surface abrasion. To reduce skirt and ring groove wear. 1.2 CONNECTING ROD Connecting rod is a part of the engine which connects the piston to the crankshaft. This connecting rod converts the linear motion of the piston to rotating motion to the crankshaft. 1.2.1 OPERATIONAL REQUIREMENTS AND SERVICE CONDITIONS [] Connecting rods should be made as long as possible to reduce the oblique angle by the cylinder axis. Both tensile and compressive stresses are produced due to piston reciprocating-inertia loads. In order to evade scuffing proper lubrication is needed. Lubrication of the small end by a hole drilled along the shank should be so arranged that the hole intersects the big end bore circumferentially. To prevent buckling the rod shank is made in an H section, i.e., with a central web and two end flanges. Intense heat is generated at high rotational speed, so large bearing area is required to make the rod wear well. They should be checked for the correct length, weight distribution, straightness and freedom from twist. 1.2.2 FUNCTIONS OF CONNECTING ROD As the word is self explanatory, the connecting rod connects the piston and the crankshaft. The connecting rod continuously transmits energy from the combustion chamber to the crank shaft. It actually converts the reciprocating motion of the piston to the rotary motion of the crankshaft. These dynamic motions of the connecting rod makes it as light as possible whilst having a rigid section. 14900_19847.jpg 1.2.3 DESIRABLES MATERIAL CONDITIONS Must be strong to remain rigid under loading and light enough to reduce the inertia forces. Material must have good elastic modulus. It must have high fatigue strength in order to avoid failure due to high cycle fatigue. Heat capacity of the connecting rod must be high. Must withstand buckling stress due to large compressive loads. Must be of low density to avoid bearing failure. 1.3 CRANKSHAFT Crankshaft is the central link-up for the power produced by each cylinder in the engine. This crankshaft is one of the heavier part of the engine which is to be made strong to withstand the load from the con-rod. 1.3.1 OPERATIONAL REQUIREMENTS AND SERVICE CONDITIONS Fillet areas locations are to be verified since both torsional and bending loads are experienced during its service life. Counterbalancing of weight is to be considered in order to counteract the centrifugal forces created by crankpin. The projected areas of the big-end and main-end journals must be adequate to withstand maximum cylinder pressure. After grounding should have a surface finish of 0.5 µm to minimize bearing wear. Crankshaft must have the capacity to absorb the thrust loads from clutches or torque converter. 1.3.2 FUNCTIONS It transmits power from combustion chamber to the flywheel through piston, piston rings and connecting rod. It harness and phase the individual cylinders power impulses transmitted through the mechanism of the connecting rod which converts the reciprocating motion of the piston to rotary motion at crankshaft. It changes the linear displacement due to sudden shock caused by the combustion chamber into smooth rotary motion which is the input to many devices. Crankshaft rotates in the cylinder in the cylinder block of the main bearing which supports the crankshaft which reduces the excessive wear. http://www.motorera.com/dictionary/pics/c/crankshaft.gif 1.3.3 DESIRABLES MATERIAL CHARACTERISTICS Material nominal stress must not exceed 20% of tensile strength in bending and 15% in torsion. Must have the capacity to withstand large force from gas combustion. Must have high heat withstanding capacity. Must have low thermal expansion. Must have high adequate strength, toughness, hardness, and high fatigue strength. CHAPTER 2-MATERIAL SELECTION 2.1 MATERIAL SELECTION FOR PISTON[hh] Material selection process is an integral part of the overall product development process and must be considered in the early phases of the product definition. The material chosen for manufacturing the product is based on the following consideration, Mass consideration Strength and wear consideration Heat-conduction consideration Expansion consideration Based on the above considerations the aluminium alloys satisfies all the factors comparing to cast iron and steel. Mass consideration: Since the pistons reciprocating force is high at high speed, it is necessary to turn to light material instead of cast iron and steel. It has a relative density of 2.6 when compared with 7.8 for cast iron. Strength and wear consideration: Since pure aluminium has low tensile strength of 92 to124 N/mm2 and fall of to 31N/mm2 at 300 °C, it is always alloyed with copper or silicon for piston materials which improves the strength to mass ratio. At high level of silicon, the alloy exhibits excellent surface hardness, wear resistance properties and excellent dimensional stability. Heat-conduction consideration: The better heat dissipation of aluminium-alloy pistons compared to cast-iron pistons greatly reduces the maximum piston-crown operating temperature of 250C 300C for allou pistons and 400 to 500C for cast iron. Expansion Consideration: The thermal expansion is less for Al-Si alloy which has a thermal expansin of 0.000 021 and 0.000 017 per  °C for 12% Si alloy and 22% Si alloy. Fig() CES chart 2.1.1 SURFACE CONSIDERATON: Due to high speed reciprocation of the piston there may be so many losses or issues that must be considered. In that the frictional losses in piston assembly are majorly due to generation of heat. Subsequent raise in temperature can have this effect in the operation. In order to overcome this problem, proper material with good thermal conductivity is chosen. 2.2 MATERIAL SELECTON FOR CON-ROD The connecting rods are crucial and highly stressed component of the automotive engine subjected to alternative tensile and compressive stresses. Hence the material must be chosen based on the following conditions; Good elastic modulus, High fatigue strength, Low density to avoid bearing failure and High heat capacity. Based on the following conditions microalloyed steel is chosen which meets all the requirements mentioned above. This steel has a hardness level of 20-30 HRC. Small microalloying additions of vanadium and niobium are used to increase the strength of carbon steel plates. 1.1%Mn-0.5%Cr is the best combination to obtain thee high fatigue strength. Lowering the carbon content down to 0.33% and increasing the vanadium content to control the hardness gives toughness which improves the fatigue strength of free machining grades with S and Pb. The finally obtained chemical composition is 0.33%C-1.05%Mn-0.5%Cr-0.12%V-.055%S-0.20%Pb-Ca which has fatigue strength of 26% higher than a conventional microalloyed forging steel. As for connecting rod, application of light metal like titanium alloys and aluminium alloys are been tested, due to high cost in light metal the connecting rod are made of microalloyed steel. This structure contains ferrictic-pearlitic-bainit. Fig() CES chart 2.2.1 SURFACE CONSIDERATION The connecting rod is one of the highly stress concentrated part of the automotive engine. It is known that in the four cycle engines the connecting-rod small end is particularly stressed when the con-rod is at top dead centre at the beginning of the induction stroke, since the small end is ovalized by the tensile inertial forces exerted by the mass of the piston assembly. During both the stroke condition (expansion and compression) gudgeon pin pushes the small end along the lower end of the arc, by which the compression load directly acts on the con-rod without considerably stressing the eye. The eye is therefore subjected to repeated stresses, whereas the con-rod shank stress are reversed.(10) 2.3 MATERIAL SELECTION FOR CRANKSHAFT (hh) Crankshaft are from materials which can be readily shaped, machined and heat-treated and which have desirable mechanical properties such as adequate strength, toughness, hardness and high fatigue strength and of course , low cost. The highest quality steels are usually specified for satisfying the constraints given. Metals with optimum combination of bending and the stiffness are identified by creating a charts in CES by using performance indices in axes. From the figure it is clear that the low carbon steel, high carbon steel, low alloy steel and medium carbon steel are satisfying the given constraints. Low alloy steel with chromium-molybdenum is used for crankshaft. This forging steel is suitable for medium to heavy-duty petrol and diesel-engine crankshafts. It presents no difficulty in hot working and afterwards can be easily machined to size. The alloying composition is 0.4% carbon, 1.2% chromium and 0.3% molybdenum. 2.3.1 SURFACE CONSIDERATIONS Since crankshaft is the most highly strained part of the engine with high load acting on it the following factors must be considered. Pitting failure can occur in the crank-pin Due to lack of surface integrity lack of control over stress and temperature. CHAPTER 3 MANUFACTURING PROCESS 3.1 MANUFACTURING PROCESS FOR PISTON[SS] Based on the material selected as aluminium alloys for piston, the manufacturing process is carried-out through casting because of its capability to produce near-net shaped parts at the required production rate. Hence the process selected for this component is the Gravity die casting. 3.1.1 GRAVITY DIE CASTING The pistons are produced from high-silicon alloys, such as 413.0 aluminium alloy. This alloy has high fluidity and can create high-definition surfaces through permanent mould casting; it also has high resistance to corrosion, good weldability, and low specific gravity. The universal acceptance of aluminium pistons for internal combustion engine applications is due to mainly to their light weight and high thermal conductivity.[ss] This type of casting is suitable for high volume production. The main advantages are the dimensional accuracy and surface finish. Castings ranging from few grams to 100kgs of aluminium alloy could be casted. This process could achieve higher mechanical properties than other casting by heat treatment. Since silicon has got good properties like, low shrinkage and imparting high fluidity which results in good casting. The maximum amount of silicon in cast alloy are in range of 22%-24%.(11) Manufacturing route: [ss] The h13 tool-steel mould is preheated to 200 °C to 450 °C, depending on the cast alloy and part size. Initially, the preheat is achieved with a hand-held torch, the mould reaches a steady-state temperature. Molten aluminium is heated to between 100 °C-200 °C above its liquidus temperature as shown below. Once the molten shot is in place the piston drives the mould in its place. Because of high thermal conductivity of the mould material, heat extraction from the molten metal is rapid and the metal solidifies in small channels before filling the mould completely. [9] 3.1.2 MICROSTRUCTURAL CHANGES Silicon has a diamond crystal structure and is consequently very brittle. These silicon structure damage the mechanical properties and nucleates on aluminium phosphide particles that is present in the melt as impurities. Further addition of sodium to the melt getters the phosphorous, which thereby increases the difficulty of sodium nucleation. Solidification is suppressed to lower temperature where the nucleation rate is large. This leads to remarkable refinement of microstructure. [9] Aluminium Silicon [9] From the figure above the dark feature is a shrinkage pore caused by a casting defect. This figure shows the coarse silicon plates in an aluminium matrix. 3.2 MANUFACTURING PROCESS Microalloyed connecting-rod is manufactured by a simplified thermomechanical treatment like controlled cooling following hot forging. Through these processes desired properties could be obtained without quenching and tempering treatments. Hence powder forging was selected which would conveniently satisfy the manufacturing process for the selected material and component. 3.2.1 POWDER FORGING Powder forging rods are manufactured by combining metal powders into a pre-form that is sintered and reheated to forging temperature. Then it is completely forged to its final shape and machined to its final dimensions. This mixed powder is compacted at room temperature and high pressure upto to 200 to 400MPa. At the end of the process the powdered material acquires a density of 70 to 85%. This process has resulted in fully dense shape part which makes it suitable for high performance applications where high durability and strength are required. The detailed manufacturing route of this PF process is shown below: [12] The advantages of using PF process are, Good dimensional accuracy Minimum scattering of weight Energy saving [12] 3.2.2 MICROSTRUCTURE [13] [13pdf] From the photograph of the microstructure of the connecting-rod material it is clear that the component contains pearlite and ferrite materials in composition. The above picture clearly indicates that in the powder metal connecting rods oxides are removed from the material surface by shot peening but the oxides are entrapped and remain below the surface causing the crack to originate below the surface . 3.3 MANUFACTURING PROCESS 3.3.1 FORGING [ss] The material selected for the crankshaft is forged steel which has a desirable mechanical properties such as adequate strength, toughness, hardness, and high fatigue strength. Hence the suitable manufacturing process for this steel is forging. Forging is a basic process in which the work-piece is shaped by compressive forces applied through various dies and tooling. For this forging process the dimensional tolerance range from  ±0.5 to  ±1% of the forging dimensions. At higher temperatures of about 700 °C dynamic forging recrystallisation occurs which increases the stress and strain deformation of the metal to make it hard. Manufacturing route: Prepare a slug or billet Heat the work-piece in the suitable furnace For hot forging, preheat and lubricate the dies Forge the billet in appropriate dies and in the proper sequence Clean the forging and check its dimensions Perform additional operations such as heat treatments and straightening Inspect for defects In the hot forging process to form a metal billet two or more dies are brought together to each other at a suitable room temperature in a shape of the die impression. This process follows two basic requirements, The strength of the material must be low so that the die pressure can be kept within the limits. The material should be capable of deforming without failure and should allow required amount of deformation. The flow of metal and die filling are mainly determined by (i) flow stress and cooling ability (ii) friction and cooling effects at the material interface. In this process, definite amount of heat is received by all the parts after machining in heat treatment process. This is mainly carried-out to improve fatigue and wear properties. High quality parts with moderate cost can be made by this process. Thus this process offers high strength to weight ratio, toughness and resistance to impact and fatigue to the material which is considered in the performance of the crank shaft. [14] 3.3.2 MICROSTRUCTURE Heating above recrystallisation temperature causes recrystallisation that removes the microstructure deformed and generated recrystallised grains. After eutectoid-carburizing martensite transformation takes place and a black portion near the surface is formed consisting of fine grains of ferrite and carbide. On quenching from the austentite (ÃŽ ³) phase martensite is formed. This transformation is a diffusion-less shear transformation . Martensite is too brittle in plain carbon steel for practical applications and is subsequently tempered to restore some toughness. CHAPTER 4 ALTERNATE MATERIAL 4.1 ALTERNATE MATERIAL FOR PISTON[hh] Cast iron refers to the family of ferrous alloys composed of iron, carbon ranging from 2.11% to about 4.5% and silicon of about 3.5%. They are classified by their structure ferritic, pearlitic, quenched and tempered or austempered. The equilibrium phase diagram relevant to cast iron is shown below where right boundary is 100%C. The eutectic temperature is 1154 °C and thus cast irons are completely liquid at temperatures lower than those required for liquid steels. One of the major disadvantage of the aluminium as the base metal of the piston is that it has high co-efficient of linear expansion in the range of 0.0000221per °C, compared with 0.0000117per °C of cast iron. Aluminium has twice the expansion rate of cast iron. Cementite is metastable (not completely stable) which has a tremendously low decomposition rate. However it can be made decomposed into alpha-ferrite and graphite. The graphitization can be controlled, promoted and accelerated by adding silicon, controlling the rate of cooling and modifying the composition.[ss] [15] 1.4.1 LIMITATIONS Relative density is high of about 7.8 When in tension, the presence of graphite acts as a stress riser weakens the material. Strength properties of the cast iron are significantly affected by the shape and size of graphite. Higher material and manufacturing cost. The major disadvantage is the shrinkage. 1.4.2 POTENTIAL BENEFITS Presence of graphite in cast iron improves wear-resistance as it acts as a lubricant. High carbon content-degradation of ductility and fracture toughness. Good corrosion-resistance. Easy machinability Wide range of composition and microstructures-easy weldability. 4.2 ALTERNATE MATERIAL FOR CON-ROD The alternate material chosen for connecting rod is aluminium alloyed material as it is light in weight and provides long service life to the part. The aluminium alloys are high strength-to-weight ratio, resistance to corrosion by many chemicals, high conductivity and ease of formability. The material composition of aluminium is 7.6 to 8.4% Zn,1.8-2.3%Mg, 2-2.6%Cu, 0.08-0.25%Zr, 0.10%Si, 0.15%Fe, 0.05%Mn, 0.04%Cr and 0.06%Ti. When compared to othe alloys it convinces the constrains like low thermal expansion, wear-resistant, high fatigue strength and buckling. Majorly this material is chosen based on the following consideration: Mass consideration Strength and wear consideration Expansion consideration Heat-conduction consideration http://www.streetperformance.com/ART/PRODUCTS/100687/14012-8.jpg[19] 2.4.1 LIMITATIONS It is more expensive than cast iron. Low dimensional accuracy and poor surface finish. Solidification is very slow. Occurrence of fracture in short transverse direction. Expansion rate is high when compared to cast iron with oure aluminium. 2.4.2 POTENTIAL BENEFITS Aluminium alloys can be easily machined and welded and formed. High dimensional accuracy with long service life. High yield strength in both tensile and compression. Aluminium is much better conductor of heat than cast iron. Aluminium alloys provide improved resistance to abrasion and produce strength over temperature range. Improves the performances of the piston and thus the engine. 4.3 ALTERNATE MATERIAL FOR CRANKSHAFT As the crankshaft is the heavier moving part in the automotive engine, the material selected for this part has to be strong and light. Titanium alloys having high strength with reduced weight is used for crankshaft until and unless cost is not considered, as this material is very expensive. http://amt-advanced-materials-technology.com/s/cc_images/cache_867254901.jpg[17] 4.3.1 POTENTIAL BENEFITS OF TITANIUM ALLOYS Titanium has high melting point of about1678 °C which specifies strong creep and strength above wide temperature range. The density is about 55% of steel with comparable strength. Ti alloys exists in two allotropic forms ÃŽ ± and ÃŽ ² Presence of thin oxide surface film-resistance over atmospher and sea environments including chlorine and organic chemicals. Reacts rapidly with oxygen, nitrogen and constituents in cutting tools at high temperature. 4.3.2 LIMITATIONS Embrittlement occurs during fabrication because of susceptibility of hydrogen, oxygen and nitrogen. Forging with titanium alloys is expensive but it increases the strength of the material. Ti alloys has a tendency to madden when tightening with connecting rod using bolt. Titanium is more difficult to machine due its reactive nature. Niobium Titanium[16] CHAPTER 5 ALTERNATE MANUFACTURING PROCESS 5.1 ALTERNATE MANUFACTURING PROCESS FOR PISTON 5.1.1 SAND CASTING Sand casting is a one of the most feasible manufacturing process where the unit production is comparatively less. In this process a mixture of sand and clay is compacted around the pattern in which the pattern retains the shape of the original component to be produced. Then the pattern is removed in order have the cavity in the shape of the pattern. Generally low cost wooden patterns with gateways and runner are used. The molten metal is poured into the gateway by which it runs through the runner and fills the cavity and forms the exact shape of the cavity. Actually this whole system is housed in a box called flask. After which the molten metal allowed to solidify by cooling it. As the molten metal is solidified the sand pattern is broken and final work is done to obtain the finished component. The figure below shows the manufacturing process of the sand casting in detail. http://openlearn.open.ac.uk/file.php/1689/T173_2_020i.jpg Fig(8.1) Sand Casting Process [18] 5.1.2ADVANTAGES Low tooling and equipment cost Component with any complicated shape can be produced Relatively cheap process Possibly components can be produced in large quantity. 5.1.3 DISADVANTAGES High tolerance ratio is required Labour cost is high. 5.2 ALTERNATE MANUFACTURING PROCESS FOR CON-ROD 5.2.1 SQUEEZE DIE CASTING Squeeze die casting or liquid metal casting involves the process of solidification of molten metal under high pressure. The machinery includes a die, punch and ejector-pin. Under the pressure applied by the punch keeps the entrapped gases in solution and the rapid heat transfer takes place at the die-metal contact which results in fine microstructure with good mechanical properties.[ss] Elimination of shrinkage and gas porosity happens because of precise metal metering, quiescent die filling and high pressure. 5.2.2 ADVANTAGES Precise dimension, Excellent surface finish, Fully shaped component is obtained Complex part can be made to near-shape. 5.2.3 DISADVANTAGES High initial cost Limitation of high fluidity metals[20] 5.3 ALTERNATE MANUFACTURING PROCESS FOR CRANKSHAFT 5.3.1 FORGING In forging operations the metal is squeezed to shape by die in which the metal is subjected to large plastic deformation. These metals are placed in-between closed dies under high temperature and pressure which results in succession of the final shape. http://www.forcast.ca/images/00436_faq1.gif[21] Forgings generally are subjected to additional finishing operations, such as heat treating to modify properties and machining to obtain accurate final dimensions and surface finish. 5.3.2 ADVANTAGES Good utilizations of materials Good dimensional accuracy High production rate Good reproducibility Low die costs 5.3.3 DISADVANTAGES Initial cost is high Not economical for small quantities Machining often necessaries

Spiritual Views in Emersons The Poet Essay -- Emerson Poet Essays

Spiritual Views in Emerson's The Poet Transcendental, and therefore pantheist, views run fluidly throughout Emerson's texts, especially as he attempts to define his image of the perfect poet in his essay, The Poet. He continually uses religious terms to express his feelings, but warps these terms to fit his own unique spirituality. This technique somewhat helps to define his specific religious views which mirror the view of transcendentalism and pantheism. Emerson's ideal poet is a pantheist who can express the symbols of the world through words. Emerson begins the essay by explaining that many people are taught "rules and particulars" to decide what is good art, and therefore deem themselves worthy critics although they have no feeling for art in their soul. He states that intellectual men, perhaps the cold Unitarians from which he broke away, theologians, and modern 'poets' do not acknowledge a relationship between the physical world and the mind and then praises the "highest minds" (such as Swedenborg, Plato and Heraclitus) who instead examine everything to its fullest manifold meaning. I find it interesting that in the lines "We were put into our bodies, as fire is put into a pan" and we are "but children of the fire, made of it, and only the same divinity transmuted, and at two or three removes, when we know least about it" that Emerson compares human souls to fire. Heraclitus believed that fire was the essence of everything, similar to Anaximander's concept of 'apeiron.' Emerson here shows his pantheistic view that we have all come from the same divine 'stuff,' and being "two or three removes" away from its Godly source, we are unable on a basic level to fully comprehend it. This is also remin... ...his ideal poet, and in doing shows that he feels the "poet is representative," both in using words as representative symbols and as a representative of life itself. The ideal poet becomes a portrait of a man incredibly close to nature, and therefore close to Emerson's view of God. The poet is a spiritual man who transcends our man made reality through introspection into the abyss of 'God's Reality,' bringing back with him carefully sculpted words for man-kind's consumption in an effort to help man-kind better understand life and the world in which it is lived.

Government and Politics - The Benefits of Federalism :: Exploratory Essays Research Papers

Government and Politics - The Benefits of Federalism In the early days of the United States, it was obvious to many that a system combining both federalism and representative democracy was needed. According to the textbook, â€Å"the people were too widely dispersed, and the country’s transportation and communication systems too primitive to be governed [solely] from a central location† (pg. 58). Although today both communication and transportation are highly advanced, America still maintains a federal system. The driving force behind that system is our increasingly expanding diversity. The United States ranks fourth in the world in size (www.stats.demon.nl/chart.area25.htm) and third in population (www.census.gov/ipc/www/idbrank.html). There are 213 languages spoken in America (www.sil.org/ethnologue/countries/USA.html) and probably just as many religions practiced. Federalism is the method by which this diverse population is better represented in the democracy of the United States. The national government makes many important decisions that impact our daily lives; however, there are some issues on which the opinion of the American public varies widely. In our federal system, the states are usually responsible for making policies that involve social, family, and moral/religious issues. This is one of the most important advantages of a federal system. The decentralization of the government allows the desires and needs of smaller groups of people to be acknowledged and fulfilled at the local level. Californians differ in many ways from residents of Arkansas who differ greatly from Alaskans. Variations in culture and lifestyle create needs for different political policies. A large, single, centralized government would be unable to make efficient social policies that were compatible with the convictions of a majority of America’s diverse groups. However, the national government still has enough power, through a system of checks and balances , to obliterate local policies that infringe upon the human rights of smaller factions. Federalism is not, of course, without disadvantages. To begin with, more levels of government equal a larger bureaucracy with many more people involved in the decision-making process. This provides more opportunities for corrupt government officials. Federalism also means that a complex tax system must exist so that each level of government receives funds from those in its jurisdiction in order to carry out laws and policies.

Genetically –modified food of persuasion Specific Purpose: To persuade our audience that genetically modified foods are not safe for consumption. Central Idea: Genetically modified foods may bring a new allergen that we may not be prepared to treat. We put more synthetic toxins into our bodies. I. Introduction A. (Attention Getter) Soon, kids may actually have a good reason not to eat vegetables. Genetically modified foods, vegetables and fruits, â€Å"Frankedfoods†, are making their way from science labs to the dinner table.B. (Thesis Statement) The processed food that has the entire chemical added in it in order to make the food to last longer has the effect of harming the people due to the fact that everyone has their own reaction to certain chemicals. C. (Justification) Currently genetically modified (GM) crops are grown in more than 25 countries. Big transitional companies are carrying out dangerous global experiment by introducing large numbers of genetically modi fied foods into our diet. D. Speaker Credibility) I work at the fast food industry for about six years and I know fast food is bad but I didn’t know how bad it really is. After researching and reading articles about engineered food I have learn so much more what the food contains and it is shocking. E. (Preview of Main points) 1. First I will discuss the health problems of GM foods. 2. Next, how it is important to label the food, and how the government should be involved. 3. Lastly, how we can stop genetically modified foods.

Disability Discrimination In The Work Force

Disability refers to the state in which a person may be physically or even mentally impaired. Impairment may limit a person from performing certain tasks. Disability may either be in form of a terminal disease or physical like the inability to use some parts of the body. People with disability have for quite some time been sidelined especially in the carrying out of public duties. Discrimination has especially been rampant in the working areas and in job markets. There has been believe that physically or mentally challenged persons are unable to perform tasks like the other persons. Another form of discrimination is the racial discrimination.Person subjected to this kind are often thought inferior to their counterparts. This may subject them to rejection in job markets regardless of their qualifications. Despite the many laws relating to the rights of the disabled persons, employment rate is still high rated as current estimates have discovered. The issue of discrimination has raised concern especially with organizations which protects and fights for the disabled human rights. It has been found out that many physically challenged individuals have the capability to perform similar jobs with other persons. They also compete fairly in the job areas.There is thus need to create favorable environment for such individuals. Challenges faced by the disabled persons at work places A study conducted in March 2008 by David Grinberg on job discrimination showed an increase of 9% in a span of five years. Out of this, 14% were disability related discrimination. Job places have been identified as areas where physically and mentally challenged persons are highly discriminated. To begin with, to get a job for these people takes much longer than for their counterparts. Employers are usually prejudiced and end up turning off disabled persons even when they qualify for the jobs.This has led to high levels of unemployment for the disabled persons, (Grinberg & Nazer para. 2). Potent ial employers also site the lack of facilities to accommodate them. They argue that the cost of accommodating them is high which may only mean additional cost to the businesses. They are afraid that the disabled persons may not perform as expected which may lead to a decrease in their output thus profitability. Also most building has not been constructed in a way to accommodate especially the physically challenged persons. This poses a major obstacle even to the potential employers (Grinberg & Nazer para.3).In the jobs however, the situations are not much different for the disabled. They suffer discrimination from they colleagues at work and even sometimes from their employers. This is usually notable by the exclusion they face from the social cliques of other employees. They are also looked down upon and the environment is usually not so conducive for them. They also tend to be segregated from the major activities in their work places. This has led to high turnover for the disabled and even worse a low morale in their work. Promotion for the disabled also comes in hardy in the job areas.Though they perform fairly the same with their counterparts, or even sometimes better as research has discovered, their labor is barely recognized by their employers (Barnes, et al pp. 27). Harassment in job areas for the disabled is also high. For a long time, the disabled have been equaled to beggars. Some employees feel that they are helping the disabled and it’s not really for job purposes. They thus end up threatening them with dismissal with others demanding for special offers from these kind of employees. Harassment has also been seen in the area of granting leaves and in termination.Most disabled persons are rarely granted family leaves and when they do; their allowances are scrapped off (Australian Public Service Commission para. 3). This has led to a cry of justice in the recent past with people calling for enactment of laws to protect the disabled. Ignorance of the rights of the disabled has also led to an increase in harassment behavior in the job areas. The disabled persons are unaware of the set rules which protect them from these practices. Other forms of harassment may include comment or actions aimed at demeaning their subject or conduct meant to intimidate its target person (Barnes, et al pp.34). Sexual harassment on disabled person at work places has also been reported. Employers take advantage of especially the mentally challenged persons to exploit them. This has challenge has been camouflaged by the lack of well coordinated government and welfare associations. The aggrieved parties thus do not know the right channels to use to seek for assistance (Barnes, et al pp. 43). Most mentally disabled person face challenges in the work place because unlike their counterparts, they tend to be slower. The organizations have not set up enabling environment to accommodate them.This has in turn lead to criticism and accuses of laziness. Su ch persons are demoralized as they are led to believe do not measure up to others. Physically challenged individual also find it hard in areas where they are restricted due to their disabilities (Australian Public Service Commission para. 4, 5). Most offices for example have no places for wheeling the wheel chairs making it impossible for these persons. Others affected by office arrangements are the blind. Many organizations lack facilities for them and if they do, they are rarely updated. This makes the disabled to lag behind in matters of technology and information.Most disabled person also requires adjustments in their working hours. This however is not provided in the job places thus posing a major block to this people. There are also few job varieties available for the disabled persons. This leads to high potential of them being under-utilized. This jobs are most often low paying and with low prospect of promotion (Australian Public Service Commission para. 8). Apart from job r elated areas, the disabled are better talented in other areas than their counterparts. However, this potential is always not recognized as they are not included in the organizations out of office activities.Also, whereas the management offers training to the other employees, this is not so with mostly the mentally and visual challenged employees. The management sites high costs for such training thus rendering these employees unproductive and inefficient. For the physically impaired employees, no arrangement is done for them to attend job related seminars. This diminishes their chances of promotions (Daniel pp. 4). Disabled persons also face problems of low esteem at work places. This is because they are led to believe that they are less endowed than their counterparts.This in turn may lead to poor performance which ultimately leads to dismissals. Interpersonal relation between the disabled and the rest is characterized by prejudices from both sides. This leads to formation of unhea lthy social classes thus tension at work places. Many laws have so far been passed regarding the plight of the disabled. The public seem to be ignorant of them; this calls for public awareness and education on how to handle people with disabilities. However, the physically, mentally and visually challenged persons have a role to play to ensure that these practices are done away with in working places (Daniel pp.7).Disability should not be a reason to make one look down his abilities or even allow other to do so. They should work to ensure that all the prejudices surrounding them due to disability are eliminated (Taylor pp. 12, 13). They should also learn to fight for their rights at job places. Disability rights should be well explained to the employers as well as other employees to ensure that such conflict does not arise in job areas. Conclusion The government should ensure that they set up agencies to look into the plight of the disabled persons.These people should also be synthe sized on these matters and encouraged to seek legal actions against a person violating their rights. The employment laws should also be revised to ensure the correct working environment is created and the necessary adjustments are made to accommodate the challenged persons. Employment agencies should also be set up to help link the disabled persons with potential employers. Managers should also be given funding and other support necessary so as to reduce the costs associated with employing the disabled persons (Taylor pp.17).Lack of proper and up to date information to the disabled persons has also been noted as a major drawback at the work areas. The government should ensure that these people are taught relevant and current affairs so as to be competitive enough at their work areas. Organizations should also set measure to ensure that all the employees are well represented in all educational issues. This would help raise the morale of the disabled persons and as well help improve t he inter-relations among all employees.

Nuclear Technology

One question that has caused a great deal of controversy over the years is nuclear technology. Although it offers a number of advantages in world peace and green power, it is also a dangerous technology. In this essay I intend to show how these benefits outweigh that disadvantage. The opponents of nuclear power generally base their arguments on the danger it represents to the world. There are two main dangers: the risk of nuclear warfare and the nuclear disasters. If one thinks about Chernobyl, it is easy to understand why people are worried about nuclear power, as it can cause major suffering. There are, however, two good reasons for believing that nuclear technology is generally advantageous. The first of these is that there has not been a major world conflict since the invention of nuclear weapons. While there have been wars, they have not been on the same scale as the Second World War. It is possible to say that the world is a safer place because of nuclear weapons. The other most significant benefit relates to the environment. Perhaps the greatest danger facing our world today is a combination of global warming and the greenhouse effect. This danger is caused partly by burning fossil fuels which leads to our polluted atmosphere. Nuclear power, however, is a much greener alternative which does not have such negative effects. Furthermore, in the last 50 years there have not been too many nuclear disasters and many experts claim that it is in fact a safe technology. In conclusion I would say that nuclear technology is better than the current alternatives. However, I also believe we should keep looking for ways to make it safer.

Unit 3 Theoretical Criminology Anomie Theory Essay

Unit 3 Theoretical Criminology Anomie Theory - Essay Example Indeed, the above fact can be used to account for white-collar crime. Of interesting to note is that mertonian approaches leaned towards white-collar crime and the anomie theory was used in explaining this kind of crime. This is based on the fact that the theory tends to explain why crime occurs and as such this can be used to explain why there is occurrence of white collar crime. Notably, criminals adopting cultural endorsed objective or goals of financial success illegally mainly characterize white-collar crime. Most white-collar crimes are related to the need of the offenders to gain money or other stuffs in order to fit in particular social classes or culture. This is more seen in criminals who are out there to become richer than before. As such, social and cultural factors, as considered by Merton, influence white collar jobs (Gomme 56). To emphasize on this, some researches carried out have showed that most convicted white collar criminals were caught while still working and they claim that they were trying to achieve economic success through illegal means (Akers and Sellers 45). As such, they can be said to be innovators given that at the time of committing crime they were after economic success. Innovators are considered to be those individuals who continually embrace material and monetary success as a goal to follow; however, they turn to criminal activities to achieve this success. Street gangs are groups formed mainly youth who are not capable of obtaining what they require through conventional means. Indeed, through these streets groups, the individuals find money and friendship and most of what they desire. Using strain theory, one may attempt to explain how various factors such as homelessness, poverty, lack of opportunity and parenting largely contribute to the formation of crime and crime (Warner and Flower 511).

Methods of Investments Essay Example | Topics and Well Written Essays - 750 words

Methods of Investments - Essay Example Money market accounts are a type of savings account, in which money is invested at a high-interest rate, with high restrictions on its withdrawal.A money market account offers a very high rate of interest on the amount deposited. Furthermore, the interest is compounded daily, and paid monthly, which means that the interest amount keeps on increasing based on the compounded interest. This normally pays off the highest, and it is safe due to the fact that most money market banking systems are insured by Federal Deposit Insurance Corporation.There mostly is a high cap on the minimum amount that may be left in a money market account so most banks might not even accept the $1,000 as a deposit amount. Furthermore, there are restrictions on the number of transactions that can be made per month which limits user control, and there are high transaction fees as well. All these things have to be kept in check when a money market account is made.A passbook savings account is one for which all tr ansactions including deposits, withdrawals, and interest, are recorded in a passbook accessible to the account holder. This is updated by the bank on a routine basis.A passbook savings account allows the account holder to observe his banking trends and extract profitable patterns from the records. Also, this account has a higher degree of transaction freedom than a money market account. Thus it is beneficial to those account holders who have a keen interest in the trends and they do not need a monthly statement.
