The Special Properties Of Concrete Construction Essay

The Special Properties Of Concrete Construction Essay Admixtures are used to give special properties to fresh or hardened concrete. Admixtures may enhance the durability, workability and characteristics of a given concrete mixture. Admixtures are used to overcome difficult construction situations, such as hot or cold weather placements, pumping requirements. The use of admixtures to increase the workability or to accelerate the hardening of the concrete will be permitted when approved by the Engineer. Admixture dosages shall result in the mixture meeting the specified plastic and hardened properties. The major reasons for using admixtures are 1. To reduce the cost of concrete construction. 2. To achieve certain properties in concrete more effectively than by other means. 3. To maintain the quality of concrete during the stages of mixing, transporting, placing, and curing in adverse weather conditions. 4. To overcome certain emergencies during concreting operations. CHAPTER 2 Set Retarding Admixtures Set retarding admixtures are water soluble chemicals that have little or no other effect than to delay the setting of the cement. They do not plasticize significantly and have little or no effect on the water demand or other properties of the concrete. Set retarding water-reducing admixtures not only delay the setting of the cement but are also efficient in plasticizing concrete or reducing its water demand. Most commercially available retarders are of this type. Retarding water-reducers and retarding high range water reducers are used to: Give workability retention to the concrete Delay the setting time of concrete Prevent the formation of cold joints Increase initial workability Increase ultimate strength Produce economies in mix designs Materials Used The main types of chemical used for retarding admixtures are: Sucrose and other polysaccharides Citric acid Tartaric acid Salts of boric acid Salts of phosphoric, poly-phosphoric and phosphonic acids. The main types of chemical used for retarding water reducing admixtures are: Hydroxy carboxylic acid salts Hydroxylated polymers Lignosulphonic acid salts These may be also be used in conjunction with sulphonated naphthalene/melamine-formaldehyde condensates or polycarboxylates to produce retarding high range water reducing admixtures. The retarder molecule chemically adsorbs onto the cement particle in a mechanism similar to that described for water reducers. The main difference is the strength of the chemical bond that is formed. This strongly links the retarder molecule onto the cement surface, blocking and slowing down the rate of initial water penetration into the cement. Retarder molecules also chelate calcium ions in solution, slowing the crystallization of portlandite. These two mechanisms slow the growth of hydration products, delaying the stiffening and setting of the cement but once initial hydration starts, the retarder molecules are swamped and normal hydration proceeds. Uses 5.1 Admixture Selection Where predictable set retardation is required, a retarding admixture is the best choice. Where set needs to be continually amended, a graph of dosage rate versus setting time can be determined for a given mix, at a given temperature. For phosphate based products, the retardation time graph may often be linear, and this is a major advantage for this type of retarder. Sucrose and other polysaccharides are more efficient, but a dosage versus setting time graph may often be exponential, making accurate prediction more difficult. These types are often blended with lignosulphonate to produce cost effective, retarding/water reducing admixtures. Hydroxy carboxylic acid salts will often reduce cohesion in the mix potentially enhancing bleed and segregation. Polysaccharides, especially if blended with a lignosulphonate, tend to stabilise some air and may enhance cohesion.The choice between the different types of retarding water reducing admixtures is often determined by other properties such as mix cohesion. Selection may therefore be based on the particular mix characteristics of the concrete. 5.2 Dosage Retarding admixtures based on phosphates and phosphonates are designed to have a linear effect of dosage upon setting time. The dosage rate used may be quite high, as they do not have any effect other than retardation. Depending on the molecule chosen, typical dosages are 0.1% to 3.0% by weight of cement to yield a delay of set of 1 hour to 35 hours. Retarding admixtures based on sucrose and other similar polysaccharides are very powerful, and their retarding effects are rarely linear so that small increases on the intended dosage can lead to large increases in retardation. They are very cost effective, but are more difficult to control than the higher dosage phosphate based types. Typical dosages are 0.1% to 1.5% by weight of cement to yield a delay of set of 3 hours to 50 hours. Retarding water reducing admixtures are very commonly used at a low dose, typically 0.2% by weight of cement, to reduce the water content of the concrete by 7 to 10% with only a small delay in setting. They can be used at higher dosages; typically 0.3 to 0.6% to reduce water content, but simultaneously to delay the setting time. Greater water reductions may be achieved by using retarding high range water reducers, generally at 0.5 to 1.5% dose, depending on the type. Retarders are quite sensitive to temperature. At low temperatures retardation will be further extended. At very high temperatures, the converse is true and it may be difficult to achieve the required workability retention and extension of stiffening time. 5.3 Cement type Retarding admixtures and water reducing retarding admixtures can be used with all types of Portland cement, including all those covered by EN197-1. However, it is very important to note that their effectiveness in terms of retardation of set is very dependent upon the type of cement. Cements such as CEM1 require the highest level of retarder to achieve a given level of retardation. However, as the proportion of slag or pulverised fuel ash, as used in CEM 2 and CEM3 types increases, then the level of retarder will decrease in order to achieve a given level of retardation. The chemistry of the cement is also important in determining the effect of retarders. Cements low in tricalcium aluminate (C3A) require significantly less retarder for a given degree of retardation than normal cements. 5.4 Yield Retarding admixtures do not have any significant effect upon the yield of concrete. Retarding water reducing admixtures, when used to reduce the water content of concrete, will reduce the yield in direct proportion to the water reduction made. This needs to be taken into account when modifying the mix design. 5.5 Overdosing The level of retardation achieved is related to the dosage used. Any overdose will result in an increase in setting time. Large overdoses of retarders can produce very long setting times and even small overdoses can have this effect if the initial dose is high. Provided the overdose is no more than double that which was intended, and the concrete is well cured to prevent it from desiccation, accidentally retarded concrete will normally set and recover strength within two to three days. Where a dosage range is given, the normal dose should be taken as the bottom of the range. Where very large, accidental overdoses occur or where large overdoses of a water reducing retarders have been used without a correspondingly large water reduction, the concrete may not recover its strength in a reasonable time. As a general rule, if concrete contains an overdose of a retarding admixture and has not set hard in 5 days, then it may not gain useful mechanical strength within a reasonable time. Effects upon properties of concrete 6.1 Strength As with water reducing admixtures, ultimate strength gain is increased with increasing water reduction Retardation of set allows the slower formation of a more ordered, smaller, denser cementitous matrix. This has the effect of increasing ultimate strength relative to an unretarded mix with the same water cement ratio. Acceleration of strength by heat produces the opposite effect, with the rapid formation of a coarse matrix. This explains why steam cured precast concrete rarely produces the same ultimate strength as concrete cured at normal temperatures and produced from the same concrete. 6.2 Workability Retarding admixtures do not have a significant effect upon initial workability. However, they generally have a beneficial effect upon workability retention, particularly at elevated temperature. Retarding water reducing admixtures, have a pronounced effect upon workability. Typically, an increase in slump of 60-100mm results from the addition of a dosage of 0.25% by weight cement. Set retarding high range water reducing/plasticizing admixtures may be used to enable workability to be increased to a greater extent, at a typical dosage level of 0.3 to 1.0%. 6.3 Slump loss Retarding admixtures are useful for helping to reduce slump loss, particularly at elevated temperature but it is still important to have a high initial workability. Retarding water reducing admixtures are very effective at reducing slump loss when used to increase the initial workability of the mix, but less so when used as a water reducer. Indeed, if water reduction is taken at the expense of high initial workability, initial slump loss may be slightly faster and will slow when about half the initial slump is reached. 6.4 Setting time The prime function of a retarder is to extend the setting (stiffening) time of concrete, usually in order to prevent the formation of cold joints between deliveries of concrete. Even if workability has fallen to almost zero slump, fresh concrete can be vibrated into, and will bond with, a preceding, older pour. In hot weather, even a small delay in deliveries or a short breakdown of the pump can result in the first concrete pours setting before subsequent pours can be placed and vibrated to form a monolithic joint. In deep pours, if concrete placed early starts to set, the heat generated can cause faster setting of concrete above it and again lead to cold joints. In this situation, retarder dosage can be progressively reduced as the pour proceeds. 6.5 Air entrainment Retarding admixtures do not normally entrain air, and some types, especially those based on hydroxycarboxylic acid, may actually reduce air content. This may cause these retarded mixes to feel harsher and have more tendency to bleed. Most types of retarder can be used effectively in combination with an air entraining agent. 6.6 Bleeding The total volume of bleed water arising from concrete is often related to its setting time because once setting starts, bleeding stops. Thus retarded concretes are always more prone to bleed. Any reduction in air tends to aggravate this potential problem. The plasticising component of a retarding water reducing admixture may help to offset this effect and some types are formulated to slightly air entrain in order to reduce bleed. 6.7 Heat of hydration Retarding admixtures do not reduce the heat output of concrete but do serve to delay the time of peak temperature rise by exactly the same time interval by which it was retarded. In small sections this may allow slightly more heat dissipation and so peak temperature may be a little lower. In thick sections there will be no reduction in peak temperature and there is evidence that the peak temperature may even be increased slightly. 6.8 Volume deformation Creep and drying shrinkage are not significantly affected by the inclusion of retarding admixtures. If the concrete is water reduced by the use of a retarding water reducing admixture, then drying shrinkage will be reduced. 6.9 Durability Provided that the concrete is correctly cured, then retarded concrete should be stronger and just as durable as equivalent plain concrete. However, because of the extended plastic stage, more attention needs to be paid to protecting the concrete before it sets. Retarded water reduced concrete will have a lower water content than the equivalent plain concrete, and will be correspondingly more durable. MECHENISM OF RETARDING ADMIXTURES Retarding admixture is an admixture that retards the setting of concrete. A retarding admixture causes cement set retardation by one or more offollowing mechanisms: (1) Adsorption of the retarding compound on the surface of cement particles, forming a protective skin which slows down hydration; (2) Adsorption of the retarding compound on to nuclei of calcium hydroxide, poisoning their growth, which is essential for continued hydration of cement after the end of induction period; (3) Formation of complexes with calcium ions in solution, increasing their solubility and discouraging the formation of the nuclei of calciumhydroxide . (4) Precipitation around cement particles of insoluble derivatives of the retarding compounds formed by reaction with the highly alkaline aqueous solution, forming a protective skin . Detailed Explanation According to the first mechanism, a retarding admixture is adsorbed on the surface of cement particles. This layer of retarding admixture around the cement particles acts as a diffusion barrier. Due to this diffusion barrier, it becomes difficult for the water molecules to reach the surface of the unhydrated cement grains and hence the hydration slows down, and the dormant period (period of relatively inactivity) is lengthened. Due to the slow hydration, no considerable amount of the hydration products giving rigidity to the cement paste will be formed and thus the paste remains plastic for a longer time. Later, when the admixture is removed from solution by reaction with C3A from cement or by some other way it is removed and incorporated into the hydrated material, further hydration is eliminated. On first contact of water with cement grains (C3S and C2S) calcium ions and hydroxyl ions are rapidly released from the surface of the cement grains. When concentration of these ions reach es a critical value (at which the solution becomes saturated), the hydration products calcium hydroxide and calcium silicate hydrate start to crystallize from the solution and then hydration proceeds rapidly. According to the second mechanism, a retarding admixture incorporated into cement paste is adsorbed on the calcium hydroxide nuclei and prevents its growth until some level of super saturation is reached during the induction period of hydration. Thus, retarder lengthens the induction period by causing an increase in the level of calcium hydroxide super saturation before crystallization begins. This is analogous to the poisoning of crystal growth of calcium hydroxide by the retarding admixture as both calcium and hydroxyl ions are present in the solution but unable to precipitate as a result of poisoning of the calcium hydroxide nuclei. According to the third mechanism, a retarding admixture incorporated into cement paste forms some kind of complexes with calcium ions released by the cement grains during the first few minutes. Formation of the complexes increase the solubility of cement, i.e., increased concentration of Ca2+, OH, Si, Al and Fe in the aqueous phase of the cement pastes will occur when hydrated in the presence of the retarding admixture. Thus the calcium ions and hydroxyl ions will accumulate in solution and will be unable to precipitate to form calcium hydroxide. For example, when ordinary Portland cement is hydrated in sucrose solution, lime is solubilised and a sucrose calcium complex (R -O à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ca+ -OH) is formed in which Ca+ -OH group is attached to the five membered ring (R) of the sucrose molecule. Such sucroseà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬calcium complex will be able to become absorbed on the growing calcium hydroxide nucleus. The adsorption of the complex on the calcium hydroxide nucleu s will inhibit its growth as the calcium and hydroxyl ions will not be able to precipitate. In this way, hydration is retarded. The fourth mechanism is similar to the first but here some kind of insoluble derivatives of retarder are formed by reaction with the highly alkaline solution as pH of the solution rises to over 12 within few minutes after first contact of water with cement. For example, inorganic salt admixtures (borates, phosphates, zinc and lead salts etc.) give insoluble hydroxides in alkaline solution. The cement hydration is suppressed through the precipitation of protective coatings of these insoluble derivatives around the cement grains.

The War on Drugs Essay -- Essays Papers

The War on Drugs To fully understand the significance and the seriousness of a War one must first fully understand the reasons that caused it in the first place. In this specific case the solution begins with several important yet seemingly simple questions†¦What is marijuana? How is it used? And why is it so coveted and widely distributed in Jamaica as well as the rest of the world?†¦ All these questions help clarify the reasoning behind the war on drugs and further investigation shows how Jamaica ends up being an important country in this puzzle as well. Lets begin with the first question, (What is marijuana), of course the dictionary definition is simply put,-a preparation of the hemp plant, Cannabis sativa, for use as an intoxicating hallucinogenic drug; applied to a crude preparation of the dried leaves, flowering tops, and stem of the plant that is generally smoked. However, beyond this explanation is what is commonly known as weed, which is simply an alternative to tobacco that results in sensational relaxed feeling that is described as high. This drugs origin can be traced back to ancient days when it was used as a healing supplement to cure several different medical conditions; its been used as a drink as well as an eliminator of menstrual pain and even more ironic marijuana has served as a religious connotation as well. However, the most commonly known usage of marijuana (after its being outlawed in the 1930’s) is as a drug and smoked or consumed by other means. Now that an understanding of the drug has been clarified one must look at the next important question, (Why is marijuana so coveted and distributed in Jamaica as well as the rest of the world?) Although marijuana usage and distribution is illegal ar... ...oes not effect the economy in a harmful way unless it is rendered illegal. This drug problem is much larger than Jamaica and should be handled as such.

A radical democrat: King’s Last Campaign

The task of this paper is two-fold; first, this paper will trace and explain the evolution of Martin Luther King, Jr.’s belief that war, racism and economic injustice are all intertwined and can be dealt with the restructuring of society’s priorities and addressed the necessity of a revolution of values; second, this paper will also explain how he carried out his beliefs in the Memphis Strike and the Poor People’s Campaign in 1968 [what the author and University of Washington professor, Michael K. Honey called â€Å"Martin Luther King’s Last Campaign†]. At the onset of this paper, it is important to note that King’s ‘background’ [which includes his race, habituation, education and religion among many others] is crucial in his struggle against racial discrimination, violence and economic injustice as experienced by blacks in the United States of America. The son of a minister, he was habituated in the teachings of Christianity and was able to attend and complete his formal education with degrees in sociology, theology and divinity. King was a pastor himself at Dexter Avenue Baptist Church in Montgomery, Alabama in the year 1953 prior to finishing his doctoral degree in systematic theology from Boston University on 1955. What prompted the Memphis Strike? Memphis in 1968 was ruled by a paternalistic â€Å"plantation mentality† embodied in its good-old-boy mayor, Henry Loeb. Wretched conditions, abusive white supervisors, poor education, and low wages locked most black workers into poverty (Honey, 2007). This characterization of the political, economic and social conditions of the blacks in Memphis in 1968 by Honey may be cited as cases of â€Å"manufactured and institutionalized oppression†. By manufactured and institutionalized oppression, I mean oppression which involves the mechanisms of law and power relations the basis of which is against the ‘natural law’. Natural law theorists, following the thoughts of St. Augustine that â€Å"an unjust law is not a law at all† and Aquinas’ notion of â€Å"law as an ordinance of reason†, view morality as essentially tied up with the very essence of law. How does King figure in all of this? How can we explain the evolution of King’s ideological perspective? The point is clear: Oppression and unfair treatment of individuals is not morally valid nor is it morally permissible most especially if the basis of such is the individual’s ethnicity or race. As the Kantians believed, each person has a capacity for rational deliberation and choice and as such, an autonomous being with dignity and therefore, ought to be respected by virtue of being human persons. The evolution of King’s ideological perspective may therefore be construed in such way that it is a product, both of his experiences as a black living in a white-dominated society and his philosophical and political development and this may be inferred from Fairclough’s book, â€Å"Martin Luther King, Jr.†, 1995. King’s speeches very clearly communicate his views: â€Å"I believe that unarmed truth and unconditional love will have the final word in reality†¦.I have the audacity to believe that peoples everywhere can have three meals a day for their bodies, education and culture for their minds, and dignity, equality, and freedom for their spirits[†¦] (as cited by Carson, 1998). Three important points about King and his political thrusts, philosophical orientation and as to why he may be called a â€Å"radical democrat† may be inferred from the aforementioned quotation. First, as a leading figure in â€Å"civil rights movement† King believed in the tenets of democracy and liberalism in the sense that he believed that both white and black Americans must have fair treatment in the realm of the law, for the purpose of law itself is the administration of social justice. Second, he believed in the â€Å"non-necessity of violence†. Influenced by Mahatma Gandhi’s â€Å"civil disobedience†, he believed that there are peaceful ways in and through which the problem of political and economic injustice may be resolved. It may further be inferred that for him, political, economic and social change can best be achieved not through violence [and that the government should not keep itself busy from going to war, as in the case of the Vietnam War] nor by transforming a portion or a sector of society but what is needed is a restructuring of the society as a whole. King believed that a â€Å"revolution of values† is a matter of strict necessity. King’s views may be identified as â€Å"radical† in this sense. He emphasized the need to restructure even how we think about black Americans or African Americans. It may be inferred that racism, the feeling of being superior over another race or ethnic group or nationality is grounded on the wrong premises; wrong modes of thinking and reasoning. It is by transforming our psyche and by appealing through reason and conscience that society as a whole may chart its rightful path towards genuine social change. Third, he believed and fought not only for civil rights but also for economic changes especially labor rights and lobbied for law reforms to be enacted to protect Negroes from exploitation and oppressive schemes adopted by employers. These include fair treatment and equal work opportunity, just compensation, etc. This is how he carried out his beliefs in the Memphis Strike and the Poor People’s Campaign. King served as a voice crying for the emancipation not only of black Americans but also of other human beings from the chains of oppression. Based on the above discussion, we can see why King believed that the problems and conflicts brought about by war, racism and economic injustice are all intertwined. What we can infer from his views is the interweaving and interconnecting patterns brought about by racism itself. But racism is not in itself the root of the problem; it is merely an effect of a traceable cause. This cause, this root of racism, is none other than a distorted value system, a wrong frame of mind resulting to feelings of superiority and even contempt and hate which further results to taking an unfair advantage of other human beings, plus a very materialistic market essentially driven by capital. The fault is, at bottom, deeply embedded with the minds of persons and a wrong value system, a wrong sense of pride and nationality, for it fails, in the Kantian sense, to respect persons for the sake of being human persons, not as mere means and tools that another person or race may use but as ends-in-themselves, possessing the capacity for rational thought, capable of making rational choices and thereby, beings that are autonomous and dignified and for the aforementioned reasons, deserve to be respected.

Chemistry Assignment Essay

Metals are mined from ores, considering yield to see if it is economically viable for a business to mine at a particular site. However, due to environmental damage and global warming, recycling has increased globally to create a sustainable future. By examining the cost and energy expenditure of recycling and extracting aluminium we can understand why recycling is a better choice than extracting metal from its ore. Discuss the importance of predicting yield in the identification, mining and extraction of commercial ore deposits Yield is the amount of product obtained or in mining terms how much (amount) a particular metal can be extracted from an ore (a deposit of minerals in which a commercial metal can be extracted from). Predicting yield in the processes of identification, mining and extraction is vital to the success of a business. For a business to compete with the global markets, the investment must be profitable and in some cases sustainable to last year’s into the future. Percentage composition is used widely in the mining industries to calculate and measure the yield of particular metal from an ore. For example, haematite (Fe2O3), a compound consisting only of iron and oxygen, can theoretically produce around 70% iron while chalcopyrite (CuFeS2), consisting only of copper, iron and sulphur can produce theoretically 35% copper. However if we express yield as a percentage of the ore dug out, an iron ore would only contain about 16% iron and for a copper ore only contain 1-5% copper. This is because an ore dug out of the ground contains unwanted minerals like dirt, rocks and other waste products which add to the mass of the required mineral ;giving a low yield percentage. Since compounds like chalcopyrite and haematite have uniform composition, ores are mixtures of useful minerals and other waste products which have variable composition (different location will yield different amounts of metals). This will affect if it is economical to mine the ore at a particular location and hence demonstrate that predicting yield is important. Predicting yield in the process of mining and extraction is important, whether extracting the metal from the ore or actually mining it, because it can determine if it is profitable or not. Extraction techniques must be efficient and sustainable. Copper is extracted through roasting it with oxygen before smelting it to form liquid copper. It is then reduced by bubbling air into the liquid copper to reduce copper sulphide to copper metal. Since this sulphur dioxide doesn’t escape fast enough, it forms blister copper with is 98% copper. Electrolysis is used to refine it. Due the significant amount of energy required and the cost involved it may seem copper is unprofitable. Yet if the copper price is high, the consumption is high, location is not far from refinery plants and factories that use copper, if there is a steady sustainable source(abundance) of copper ore and the extraction technique is efficient plus cost effective then a profit can be gained from the high cost of extraction, transport and the money needed to pay for the energy consumption. For a copper ore site to be economical it must contain at least 5% of copper or more. Haematite is extracted through reducing it with carbon monoxide to form iron (metal) which falls to the bottom of the blast furnace. Limestone is also heated in the blast furnace which decomposes and reacts with silica to form a slag that floats on the liquid iron, hence stopping iron from reacting with oxygen. High heat is needed to separate iron from oxygen since iron is reactive to oxygen and sand and limestone is needed to prevent the union of these two elements. Hence for haematite to be economically viable an ore must contain at least 20% iron as the energy needed to extract the metal is large and the world’s demand for iron is great. Since iron ore price is relatively high, a profit can be obtained from deposits of iron ore that contain more than 20% of iron. Hence predicting the yield of ore deposits is important to determine if it is profitable to mine. Justify the increased recycling of metals in our society and across the World Recycling is a process that changes waste materials into new products. In recent years, recycling of metals has increased dramatically in Australia and across the world. This is because we are more aware that recycling metals saves money, energy and causes far less pollution compared to extracting metals from ores. This is also spurred on by the fact that our metal ore deposits are depleting (going to run out) if we mine and extract metals at this rate. Hence recycling has been encouraged by organisation like Planet Ark and this has helped spread the message of the benefits of recycling instead of putting money into extracting and mining ores. ‘Reusing and recycling’ metals allow us to conserve these precious commodities so it would be available for the future generation. Demand for metals will increase as new technology will be discovered. Hence recycling is needed to return back old and useless appliance so it can be made it new useful products. Figure 1: It shows froth floatation Note: The vast amount of water used during the process Generally recycling metals use less energy (melting material requires the breaking of weak intermolecular bonds), water and cost less (less energy is needed to break the intermolecular bonds hence the cost will be minimised and new products with recycled material would be cheaper). Energy used in metal extraction comes from coal, oil or gas (as high temperatures are needed to break strong Intramolecular bonds). These fuels are non-renewable and are limited. It also releases large amounts of greenhouse gases when burnt which can cause global warming. Water is used extensively in mining during froth floatation (figure 1). This water can be better spent for human consumption as some countries are experiencing drought and this can cause famine (Africa). Also, harmful chemicals used in the extraction of some metals can seep into the soil and water making it toxic to fauna, flora and humans (figure 1. 1). Figure 1. 1: Acid mine water pollution For example, Bauxite (aluminium ore) is mined near tropical forest. This can cause irreversible damage to the environment as natural vegetation is destroyed, leaving soil bare and subjected to erosion. It can scar the land(figure 2)(removing so much soil and rock that leaves a gigantic hole in the landscape) and since many chemical process need to take place before aluminium is extracted, slag (unwanted metals) are left behind and pollutants are released into the atmosphere adding to global warming. Figure 2: Shows a mine that is extracting metals Note: The extensive invasion of the land and that it is irreversible. But recycling aluminium on the other hand doesn’t scar the land. Little to no pollution occurs and natural vegetation and fauna are not disrupted. Large amounts of rubbish are no produced and water is not needed. For every 1 tonne of aluminium that is recycled, 5 tonne of bauxite is conserved. Metals make up a small percentage of the ore. A large percentage of the ore is the gangue (consisting of dirt, sand and other material) which ends up in landfills. This reduces the space for cities to expand, limiting the number of farms and communities that can be developed and cause overcrowding. Recycling metals doesn’t take up space; hence reduces landfill, as scrap metals are mostly recycled back to make new products. Since ores are non-renewable resources (created by the Big bang and there is no way of returning it to Earth’s crust) it is conserved, reducing the amount of mines opened and environmental impacts that it is associated with. As ores high in metal concentration decrease, the cost of processing ever less pure ores increase. To compensate for the increase in less pure ores, more must be mined. This increases the price of ores making it a valuable resource which is expensive to the consumer. Recycling metals helps to lower the prices of these ores, as the metal is reused without having to mine for new ores. Metals are used worldwide for a variety of purposes from soft drink cans to aircraft bodies. Australia has recycled 63% of aluminium cans; nearly two billion cans a year with a total value estimated to be 33 million dollars. America has recycled in excess of 62. 6 billion cans in the year 2004, worth more than one billion dollars back into the economy. Since recycled aluminium is exported to other countries, Australia benefits as it generate large amounts of money; positively impacting on Australia economy and its benefit flowing into society. However, recycling can only be done if used material is collected from scattered location. The ore on the other hand is confined to one location (the mining site); where factories are often close by to produce products from the freshly extracted metals. But once the product hits the shelves it is scattered across many different countries and throughout communities. It is hard to keep track of all these products as some end up in landfill, waterways or in the people’s backyard. Collecting used material for recycling would cost money as trucks are needed to transport scrap metal to recycling centres. Hence energy (fuel) is needed to operate this machinery. In recent years (figure3), the media has focused on recycling aluminium drink cans because they are widely used and commonly dispersed inappropriately throughout the community. E. g. In waterways, storm drains and in the ocean. Recycling of others metal like iron, steel, copper and lead have always been significant but never reported as it is mainly used at an industrial/commercial level rather than by consumers. However since iron rust, it can be returned to the environment, but aluminium doesn’t corrode (if it does, it forms an oxide layer that actually protects it from further oxidation) it ends up in landfill; taking up space. The only way to ‘get rid of it’ is to recycle it so it can be made into new products. Notice that recycling of lead and ferrous materials have decreased Figure 3: Shows recycling metals Notice that when metals are recycled they can be reused to make different products. Recycling is a sustainable process, saving the environment from pollution, money, conserving natural resources and reduces landfill. Energy is also reduced as recycling requires less energy than extracting a metal from its ore. This will ensure that future generations will be able to enjoy a better standard of living. Analyse information to compare the cost and energy expenditure involved in the extraction of aluminium from its ore and the recycling of aluminium The recycling of aluminium is cost-effective and uses less energy compared to extraction of aluminium from bauxite. To extract bauxite, land must be cleared for mining. Heavy equipment like bulldozers, hydraulic excavators and explosives are used to clear and mine the ore. These equipment cost considerable amount of money and use vast amount of energy (fuel) to operate. Transporting trucks, ships, railway cars are used to transport ores to extracting facilities or shipped to other countries; cost money and again energy (fuel) is needed to power these machines. Notice the size of the person compared to the truck.

Essay Religious Study

Essay Religious Study Essay Religious Study Max Weber, the German Philosopher and an author, in his book The Protestant Ethic and the Spirit of Capitalism, theorizes the relationship between the Protestantism and the emergence of capitalism. Weber argues that the religious ideologies of group such as the Calvinist Protestantism paved the way for the rise of the modern capitalism. According to Weber, the two significant theological differences between the Protestant Reformation and the Roman Catholic Church that which brought changes in people’s belief during the 16th century were concerning the value of works and ideas of vocation. In Catholicism, the ideas of value of works require one to perform good work in order to attain salvation. In contrast, Weber found motivation in radical form of Protestantism - Calvinism - and its doctrine of predestination. Calvinist Protestants believe that God has already chosen each person for either eternal salvation or for eternal damnation. Therefore, if a person performed good deeds and were successful it was simply because they were predestined. Unlike in the Catholic practice in which one may also earn salvation through a monastic lifestyle and performing good work for others, Calvinist doctrine of predestination stated that the salvation could not be earned and there was no need of a mediator because of the preor dained fact of being saved or dammed. Weber theorizes that people could make sure, if they were among the elect through worldly activities. Weber interpreted these worldly activities as one being successful at whatever they do. The Calvinist emphasized that for a person to be successful they must invest, make profit, and reinvest all of the profit while living a frugal life. For example, a fruit vendor he re invests his profits back into his business and he was successful in his business, therefore he was chosen for salvation. However, the overall objective for an individual was to achieve the inner satisfaction and assurance that he/she is the one chosen for salvation. Weber argued that

Donne John essays

Donne John essays To say that Blake and Donne do not write uplifting poetry is a great injustice to their works. Although some of their poems discuss themes of depressing nature, on a wider scale both Blake and Donne write poetry which is not only uplifting but also inspiring and extremely worthwhile to read. The two main themes covered by these two writers are love and death. The poems which use love as the main theme inspire the reader and offer hope that true love exists and is not a fragment of their imagination. The feelings that are discussed in these poems are feelings that all people can experience but are difficult to describe and put into words. This is what makes the poetry so worthwhile to read, to see how the feelings that relate to love are expressed and how they are shown with images and other writing styles. A Valediction: Forbidding Mourning by John Donne was written to express his feelings for his lover. The poem talks about the feelings of love being so intense that nothing will ever dull the bond between the two souls. A Valediction: Forbidding Mourning is uplifting because Donne talks of a love so refined that ourselves know not what it is, in other words a love so perfect it cannot be explained. This is what makes the poem because Donne has said the love cannot be explained but then he goes on to explain what the two people are feeling and it is done in a way that can never be reproduced or attempted by other poets. This poem is as perfect as the love it describes. Donne explains how the love that is shared by the two is a love that is not affected by sensory things. care lesse eyes, lips and hands to misse, or dont think that being apart dulls this love, because the love is so strong that even the non-existence of one or both partners cannot bring an end to the intense love felt by both. A Valediction: Forbidding Mourning is also talking about death however it does not affect the uplifting na ...

How to Read and Write Binary Numbers

How to Read and Write Binary Numbers When you learn most types of computer programming, you touch upon the subject of binary numbers. The binary number system plays an important role in how information is stored on computers because computers only understand numbers - specifically, base 2 numbers. The binary number system is a base 2 system that uses only the numerals 0 and 1 to represent off and on in a computers electrical system. The two binary digits 0 and 1 are used in combination to communicate text and  computer processor instructions. Although the concept of binary numbers is simple once explained, reading and writing binary is not clear at first. To understand binary numbers, which use a base 2 system, first look at the more familiar system of base 10 numbers. Writing in Base 10 Take the three-digit number 345, for example. The farthest right number, 5, represents the 1s column, and there are 5 ones. The next number from the right, the 4, represents the 10s column. Interpret the number 4 in the 10s column as 40. The third column, which contains the 3, represents the 100s column. Many people know base 10 through education and years of exposure to numbers. The Base 2 System Binary works in a similar way. Each column represents a value. When one column is filled, move to the next column. In a base 10 system, each column  needs to reach 10 before moving to the next column. Any column can have a value of 0 through 9, but once the count goes beyond that, add a column. In base 2 or binary, each column can contain only  0 or 1 before moving to the next column. In base 2, each column represents a value that is double the previous value. The values of positions, starting on the right, are 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, and so on. The number one is represented as 1 in both base ten and binary, so lets move on to the number two. In base ten, it is represented with a 2. However,  in binary, there can be only a 0 or a 1 before moving on to the next column. As a result, the number 2 is written as 10 in binary. It requires a 1 in the 2s column and 0 in the 1s column. Take a look at the number three. Obviously, in base 10 it is written as 3. In base two, it is written as 11, indicating a 1 in the 2s column and a 1 in the 1s column. This becomes 21 3. Binary Number Column Values When you know how binary works, reading it is simply a matter of doing some simple math. For example: 1001:  Since we know the value each of these slots represents, then we know this number represents 8 0 0 1. In base 10, this would be the number 9. 11011:  Calculate what this is in base 10 by adding the value of each position. In this case, this becomes 16 8 0 2 1. This is the number 27 in base 10. Numbers at Work in a Computer So, what does all this mean to the computer? The computer  interprets  combinations of binary numbers as text or instructions. For example, each lowercase and uppercase letter of the alphabet is assigned a different binary code. Each is also assigned a decimal representation of that code, called an  ASCII code. For example, the lowercase a is assigned the binary number 01100001. It is also represented by the ASCII code 097. If you do the math on the binary number, youll see it equals 97 in base 10.

Critical evaluation of Fuchs, Fuchs & Karns (2001) article Essay

Critical evaluation of Fuchs, Fuchs & Karns (2001) article - Essay Example (Pagani et. al. 2006) Considering all these, there is growing importance placed on understanding those stages of life. This report aims at critically analyzing one of such researches done on children’s mathematical development. In this process, views of external critics are taken into account and the choice of the method applied is critically analyzed along with its results and outcomes. The other aspect that is discussed in this report is the benefits that are obtained in implementing this method and the probable ethical issues that might arise if this is to be implemented in practical scenarios. Research problem The background for this research is based on the results obtained from the analysis done by Griffin and Case in 1997. (Griffin & Case, 1997) According to them, children, when they attain the age of six, should have developed a ‘mental number line representation’ by combining the two basic concepts of mathematics – counting and comparison. (Fuchs e t. al. 2001) Once they achieve such a line, the required ground work gets established and with that as base, they can build on it to solve further problems in mathematics and understand the concepts better. But, many of the children who come from poor financial backgrounds and from utter poverty fail to achieve this line of understanding and hence wound up facing long term mathematical failures. The research under discussion aims to improve the students from high poverty background to achieve this mental line representation before they move on to higher studies. The research is actually an extrapolation of the research works done by the authors, Griffin and Case in the year, 1997. (Griffin & Case, 1997) Based on the three research exercises that they had done on a select number of students grouped under experimental and control group categories, they received high percentage of success, with many of the guided students who underwent this study were able to cope up with the middle le vel students, thus allowing them to compete equally and subsequently improve their mathematical knowledge. (Fuchs et. al. 2002) Research methodology Peer Assisted Learning Strategies of (PALS) is the method followed here to achieve the goal of this research. It is a method where the teachers deploy a program that allows them to identify and assist students who lack in specific set of areas. (Ashwin, 2003) Did their hypothesis/research problem correspond to the adopted collection and analysis of the research design? The aim of their research is to improve the understanding level of the students in mathematics. The purpose of the research problem is to extrapolate the previous results in three ways. 1. To expand the research area. That is, to involve more numbers of students, whose levels of understanding varies drastically. This is to present the teachers with details about how to proceed with the treatment in diversified classrooms. This dimension of the problem was addressed during the design phase of the research by identifying and including students with different performance levels and from both disabled and nondisabled sections. 2. To evaluate the capacity of the teachers. The need for this result was to identify the response from students, to explore the fidelity of their teaching method and to generate an informative feedback about the treatment. This dimension of the problem was addressed by choosing teachers who were from different demographical

Gender and Work - Essay Example been expected to find work and earn for the livelihood of the family, and the women have stayed home, bearing children, caring for the immediate needs of the family. From the 1950s onwards, new trends were observed as women have been prompted by financial constraints to find work and also help sustain family needs. Such trends grew to more significant proportions, to the current trends which have now been observed in society. Men and women are now equally expected to find work, have careers, or simply work for themselves, not necessarily for their families. Regardless of the seeming egalitarian situation such work conditions have created, issues on discrimination have still been observed. Moreover, such issues have also been very much apparent as far as leadership or managerial positions are concerned. The male: female ratio for managers in organizations very much favours more men occupying leadership roles. However, organizations are often quick to dismiss such trend, arguing that t he difference is mainly caused by the fact that men are more interested in gaining managerial roles, and that women can have as much chance to be leaders much as men. This argumentative essay shall analyse the issue or contention that: Women are being discriminated in the workplace in relation to leadership or managerial roles and positions. This essay shall first provide facts relating to statistical figures on women versus male leadership ratio in organizations. Next, it shall argue on one hand how women are still being discriminated against for leadership roles. A different perspective on the argument will also be presented. Also, both sides of the argument will be considered in order to indicate a logical and well-evidenced position on the issue. A conclusion will summarize the arguments and provide a clear and logical answer to the issue raised. A reflective analysis will also provide a personal perspective on the issue. Although women are already making up a huge proportion of

United Arab Emirates Law and How It Bacame United Essay

United Arab Emirates Law and How It Bacame United - Essay Example in the history of this strategic region, which later on flourished through the rearing of camels at the latter stages of the second millennium BC (Adias-uae.com). Additionally, at the beginning of the 1st century AD, overland caravan traffic begun between Syria and Southern Iraq cities. Furthermore, the existence of water prone transport to the important port of Omana, which is presently referred to as Umm al-Qaiwain, which later on ended up to India, came up. These routes played integral roles to the region since they were alternative transport zones to the Red Sea, which was mostly used by the Romans (UAE Interact). During the mid 19th Century, the United Arab Emirates economy was varied as a result of different population living in different areas and possessed different resources. Several industries came up in the UAE, including pearl fishing, dates, trade, fishing, handicraft and grazing. At this particular instance, the Bedouins and the fishermen enjoyed a simplistic type of li fe. The preceding years saw an important evolution in Abu Dhabi and Dubai due to pearl fishing and trade (Noack, 2007). The discovery of oil in Abu Dhabi in 1962 saw major transformation in the UAE. The oil boosted the economy of the UAE which ultimately made the Trucial States to gain political and national power, thus imposing adverse pressure on Britain, forcing it to withdraw from the region by 1968. This significant freedom made the rulers of the Emirates to hold a round table meeting and agree to form a union known as the United Arab Emirates in July 1971. The United Arab Emirates was formally established in on 2nd December 1971. Initially, the union was composed of six emirates of Abu Dhabi, Dubai, Sharjah, Ajman Umm al-Quwain and Fujairah. Amazingly, Ras al-Khaimah joined the union... United Arab Emirates Law and How It Bacame United Though each emirate is governed by a hereditary emir, the seven emirates are governed by a single national president. The seven emirates are; Abu Dhabi, Dubai, Sharjah, Ajman, Fujairah, Umm al-Quwain and Ras al-Khaimah. Abu Dhabi serves as the capital as well as being the state’s center of political, industrial and cultural activities. In 1971, prior to independence, the United Arab Emirates was referred to as the Trucial States or Trucial Oman. This was in reference to the truce entered between the local sheikhs, hereditary rulers and the United Kingdom in the 19th century. This paper is going to highlight the United Arab Emirates Law and how the seven principle emirates became united and formed a union called United Arab Emirates. United Arab Emirates History and Formation Sascha Noack asserts that archaeological evidence has some reasonable proof that there were settlements from as early as 4000BC. However, a population of high culture developed around 2500BC. Historical in dications suggest that the population has a major composition of Bedouins and fishermen. Prior to 1820 before the conclusion of a contract between the Great Britain and the Sheikhdoms of Abu Dhabi, Sharja, Dubai, Ajman, Fujairah, Umm al-Quwain and Ras al-Khaimah, the area was commonly referred to as Pirate Coast. while the UAE has a federal system of government, each emirate has its own ruler, has some degree of autonomy and can make its own laws, so long as they comply with the federal law.

Securing a Crime Scene Paper - Essay Example Ultimately, the importance of maintaining a contamination-free crime zones and one that is not meddled with has a profound impact with respect to the equity of the entire justice system (Lehmann et al., 2013). Due to the fact that an individual is generally charged with a crime based upon the evidence that exists at one given time, the ability to go back and retrieve evidenced in the past is not always readily available (Aquila et al., 2014). As such, the strength of the prosecution and the overall equity of the criminal justice system rests upon the ability of stakeholders to derive useful inference from a pristine crime scene that was left just as it was left by the individual responsible for committing it. Within this frame of understanding, the consequence of the contaminated crime scene relates to a situation in which scientific inquiry, police investigation, and jurisprudence is potentially led astray to understand a faulty representation of the way in which events and situatio ns actually transpired (Vivona, 2014) Aquila, I., Ausania, F., Di Nunzio, C., Serra, A., Boca, S., Capelli, A., & ...

Cross-Cultural Communication Essay Example | Topics and Well Written Essays - 1000 words - 1

Cross-Cultural Communication - Essay Example Some say relations come before work regardless of the situation, whereas other cultures may not agree with this point.   Individuals should profoundly understand the differences between cultures before starting work in any multicultural organization at the global level, which is constantly becoming more common business practice today (LeBaron). This article enhances that time and space should be the powerful and effective tool in cross-cultural communication. Time perceptions is about punctuality and willingness to wait, in addition the time impact on, people is also refer as the speediness of verbal communication that how long people are keen to listen. Time and space as referred in the article can make a great difference in terms of the future aspiration and productivity. Being a student, I have come across many people from different cultural backgrounds (LeBaron). I have noticed that students from the Far East are much more conscious about time, and they are always quick in terms of assignments submission, project activities and time management since they strongly believe â€Å"time is money†. While, students from Asia are known for procrastination in their work, Western students are relatively more punctual and follow deadlines because they consider time as money. The issues that are caused by such cultural differences with respect to time and space should be co-ordinated in group meetings (LeBaron). I suggest that in order to get away with the issues of multiculturalism in a group project as mentioned above, it is necessary to conduct a briefing session for all the members of the group. This will help in understanding the goal and dimension of the group work. In this way, members of the group will be able to refine their abilities and decide which task to work on. It is also recommended that members of the group are

Piaget and the Concrete-Operational Period Assignment

Piaget and the Concrete-Operational Period - Assignment Example The concrete operational stage, which is the element of focus, begins from seven and ends at around eleven years. It involves integration from preoperational stage and children in this stage are able to apply logical reasoning based on principles of conservation (Flavell, 1994). Beyond the concrete operational stage, a child is able o apply deductive techniques in reasoning and solving seemingly complex problems (Garcia & Nanez, 2011). The following is a play to elaborate the concept of a concrete operational period and involves four children (Adam, Isaac, Norah and Cynthia). Adam is six years eight months, Norah is seven years, Isaac is ten and Cynthia are 11 years. The mission of the play to investigate how the children were at different ages will determine or explain changes in the quantity of sugar poured in three different containers using one standard measuring container. An adult named James is going to guide the children through the play and ask questions as well as record observations. (James uses a cylindrical container of one kilogram, 10-centimetre diameter and 30 centimetres height to scoops a kilogram of sugar and pour into the three containers. The first container is cylindrical, 30 centimetres high and 40 centimetres diameter. The second container is cube and measures 20 centimetres length, 20 centimetres wide and 20 centimetres height. The container is also cylindrical in shape and measures 60 centimetres height and 5 centimetres diameter. Transfer of the sugar is such that all the contents of the scooping container fit into each of the three containers. James ensures that each child is attentive and observes the distribution process. James then asks each child to comment by showing container with most and least quantities, and explain their observations). Adam: The third container is taller than the rest and capable of holding more sugar.  In addition, the sugar has filled it near to the brim.     

The Indian Armed Forces

The Indian Armed Forces The Indian Armed Forces have long enjoyed the reputation of being one of the finest in the world. The armed forces render invaluable service to the country, in times of war as well as during peace, ensuring the security of the nation. They are also called to help restore law and order, ensure the safety of the people in times of internal strife, provide help and relief to victims of natural calamities also contribute to the building of vital infrastructure facilities like roads and bridges in remote and war torn areas. The Indian Armed Forces are facing an acute shortage of officers in all three services. The shortage of officers in the Army is around 11,500 and in the Navy, it is around 1507. Air Force is approx 1237 offrs short of its requirement  [1]  . Statement of Problem. Is there a need to enhance the social standing of Armed Forces personnel to continue to attract the right talent to serve the nation? Hypothesis Though the profession of arms is a calling not a career, lately, some decline in the status social standing of the combatants, particularly the officer cadre of the three services has been perceived. It has led to the present generation of youth preferring other professions, leading to a significant shortage of officers in all the three services. If not arrested, this trend can get aggravated and begin to compromise operational efficiency of our Armed Forces. Justification For the Study Though the subject of status of Armed Forces has been touched upon by a large number of eminent personalities, no writer has comprehensibly addressed the complete issue. The approach of all the writers was either towards financial aspirations or changing social environment or it was a fragmented effort, touching a large number of inter-related issues, eg promotional aspects social standing in civil society. Prominent writings on present day leadership challenges, change in socio economic environment, growing involvement of Armed Forces in IS duties, changes in the Warrant of Precedence etc along with practical approaches to meet the present day challenges have been drawn up by a large number of military minds, journalists, politicians eminent scholars. It is felt that there is a requirement of articulation of these works in a comprehensive manner to recommend an appropriate approach towards the issue. Scope. This paper aims to highlight the erosion in status in the Armed Forces starting from the time of Independence. The reasons for this erosion will be debated. The lack of intent and complete endeavor of defence and civil personnels will be brought to light. Finally some recommendations for making the Defence Services more attractive would be discussed. Methodology It is proposed to study the subject in the following parts:- (a) Part I. Status of Armed Forces Officers before Independence. (b) Part II. Post Independence era. (c) Part III. Pay commission effects. (d) Part IV. Warrant of Precedence Present Status. (e) Part VI. Intent and endeavor with Limitations Positives (f) Part VIII. Recommendations. Source of Data The study has been conducted based on books and columns written by eminent writers on the subject, official history and gazete notifications of GOI, newspaper articles and write ups from internet sites. A bibliography of sources is attached. PART I STATUS OF ARMED FORCES OFFICER BEFORE INDEPENDENCE Warrant of Precedence Before 1947 Status of the Commander-in-Chief. The Warrant of Precedence of British India kept the Armed Forces Officers on a very high pedestal. The Precedence in India was regulated till the independence by a Royal Warrant which was promulgated on the 6th of May 1871  [2]  . As per the Royal Warrant, the Army Chief, the erstwhile Commander-in-Chief was higher in rank to the Chief Justice of the Supreme Court while Military Officers above rank of Major-General were higher than the Judge Advocate General of India also the Secretaries to the Government of India. Status of the Major-Generals. It is important to note that First Class Civilians of 28 years standing were equated with Major-Generals while in the present day it is with IAS of 14 years of service. Similarly Civilians of 20 years standing were equated with Colonels and included Commissioners of Divisions. Status of the Colonels Below. Inspector General of Police, then the highest post in any state were similarly equated with Chief Engineers were in the same league as the Colonels. The next grade comprised of the Third Class Civilians of 12 years standing who were equated with the Lieutenant-Colonels. These comprised of the Under-Secretaries to Government of India, Inspector-Generals of Jails etc. The next grade comprised of the Fourth Class Civilians of 8 years standing who were equated with the Majors and so on. The Comparison. It is evident from the above comparison, the high esteem of the officers of the Armed Forces which they enjoyed during the era. The Inspector General was responsible for the complete state but was considered equivalent to a Colonel of a Battalion with 20-25 officers. The same was required because the State machinery was generally static but the Armed Forces were considered to be working in a volatile environment requiring split second decision making which resulted in a situation of life death. There was no requirement felt of large number of officers in the police, where the job was to catch thieves and petty criminals. This task was found suitable for the lower staff in the police forces comprising one Darogah, one Jamadhar and a number of constables who were maintained at each district headquarters  [3]  . Later the same were controlled by the Deputy Superintendent, Inspectors, Head Constables and Constables. The Indian Armed Forces as the Preferred Occupation of Royals and Dynasties The Kashtriya Way of Life. Kashtriya meaning warrior formed one of the four varnas (social orders) in Hinduism. Kshatriyas constituted the military and ruling elite of the Vedic-Hindu social system outlined by the Vedas and the Laws of Manu  [4]  . A Kshatriya was a fighting man, he was bound by the holy scriptures to govern as a Dharma-Raja, with the main duties being protection of his subjects and livestock. The people looked upon Kshatriyans to protect them from all dangers. The great kings and generals on ancient and medieval India took pride in their Kshatriya lineage and took pride in being the kings and warriors in the army. The British Age. During the British Empire, most of the royals had to give up the rights to their land. Some of the royal dynasties even acted as British protectorates. In such times, only some of the dynasties could kept their own armies but the same was not possible with the smaller states. In time, it became a tradition of the royal princesses to either join the British Indian Army or to command their own troops in their small princely states. It was considered bounteous for these princes to command troops in the old Kshatriya ways, be it in the Indian army or the state troops. Serving the Army. Due to the above reasons, the British Indian Army was always associated with the rich royalty who served its ranks often rising to the officer cadre due to their competence and efficiency. Even after independence, the tradition continued. The Indian royalty found itself in the whos who of Indian army with few of them rising up to the highest ranks while serving the Army. Some of the prominent names among them are Colonel Sardar Bahadur Muzzaffar Jung Bahadur Thakur Girdhari Singh, O.B.E, O.B.I Brigadier Th. Harish Chandra Singh, V.S.M. of Kuchela royal family  [5]  ; Capt Amarinder Singh of Patiyala royal family  [6]  ; Brig Sukhjit Singh, MVC of Kapurthala royal family  [7]  ; Brigadier Bhawani Singh, MVC of Jaipur royal family  [8]  . The tradition of joining the Army gradually started to decline with time. The reasons can be attributable to a large number of facts to include the changing socio economics, the changing of family values and the perceived social standing of Armed Forces personnel in civil society. PART II POST INDEPENDENCE ERA START OF THE DECLINE Involvement of Mil in Pakistan, Bangladesh and Mayanmar in their pol affairs During the middle of 20th Century, most of the countries in Indian peninsula got their independence. Independent India found itself sandwiched between large numbers of politically unstable states in which the military frequently thrust itself in the political arena replacing the democratically elected political leaders. Large numbers of coups were accomplished by the military in the nearest neighborhood of India which fuelled mistrust for the Indian Generals in the political circle. The political class often found itself worried because of presence of influential leaders in the military. Military coups in Pakistan began in 1958 and number three successful attempts. There have also been numerous unsuccessful attempts since 1949. Since its independence in 1947, Pakistan has spent several decades under military rule (1958 1971, 1977 1988, 1999 2008)  [9]  . On the other hand, Bangladesh had military coups in 1975, 1977, 1981, 1982, 1996 then in 2007. Bangladesh remained under military rule from 1975 1990 under two different military rulers  [10]  . Mayanmar had its share of military rule when democratic rule ended in 1962 when General Ne Win led a military coup dà ©tat  [11]  only after fourteen years of democracy. The reaction by the politicians to all of the above was obvious. Firstly the Defence Services were increasingly isolated from the process of decision making in defence matters. During the British era, India was perhaps the only country in the world which had a single Commander-in-Chief for all the three Services. In 1947, this arrangement was discarded and each Service came to have its own Commander-in-Chief, independent of each other. The nomenclature of the three Chiefs was changed in 1955 from Commanders-in-Chief to Chiefs of Staff. In this set up, the Chiefs of Staff are not part of the Ministry. They are not authorized to take any decision on behalf of the Government nor issue any Government orders. These functions are performed by civil officials in the Ministry of Defence (MoD). The Service Chiefs continue to function as Commanders-in-Chief of their Service  [12]  . Each war increased the popularity of the Indian Army among the common masses and the status of the service chiefs was lowered after successive wars in the Official Warrant of Precedence due to the perceived threat of a possible coup by the Armed Forces. Such was the popularity of eminent military leaders like Field Marshal Sam Manekshaw after the 1971 Bangladesh libration that late Indira Ghandhi feared a massive military coup in 1977  [13]  . Mistrust of the Political class fuelled by Bureaucrats. The mistrust of politicians for the military generals was always exploited by the bureaucrats in every way to increase the rift between them. The incidents of armed rebellions coups in the neighboring countries the world over always added fuel to the fire. Gradually the military generals were sidelined by their political masters the bureaucrats made a place for themselves in between the political masters the military started making important decisions which made an impact on national security matters. Tradition History of Police Ranks The Police followed the following system of rank badges till about independence : (a) Superintendent of Police / Assistant Inspector General of Police. Three Stars (Upgraded to Crown on reaching the basic pay scale of Rs 950/-). (b) Deputy Inspector General of Police. Crown with one Star. (c) Inspector General of Police (highest police rank). Crown with Two Stars. In the late 1950s and early 60s, the police establishment went in for a major overhaul and upgradation of rank badges. This followed the introduction of additional ranks such as Selection Grade etc. To meet new ranks, rank badges were appropriately upwardly modified. Contrary to popular perception, the Ministry of Defence very vehemently protested the rank confusion created by junior police officers wearing senior military rank badges but the issue was sorted out in a high level meeting between MHA and MoD (the meeting is documented and minuted) where it was rather unusually concluded that there could be no confusion between police and military ranks since police rank badges are silver in colour whereas military ranks are made of brass, and it was also decided that rank badges would not reflect the actual status comparison of military and police officers. This later resulted in the rank of DIG (then established by pay and by the MHA as being between a Lt Col and a full Colonel) weari ng rank badges as worn by a Brigadier of the Army. So far so good. But this came to haunt the military years later when by forgetting the historical background of the issue; police officers started demanding status and pay equation by virtue of the rank badges worn. The skewed situation got adversely solidified when the 6th CPC commented about an established relativity between a Brig and a DIG in all probability based on the equality of brass carried on the shoulders by the two ranks  [14]  . PART III PAY COMMISSION EFFECTS Effect of Successive Pay Commissions The Post War Pay Committee of 1946. The first attempt at rationalisation of the remuneration structure was made by the Post War Committee in 1946. The mendate of the Committee was to produce pay scales exclusively to Indian conditions, to simplify the pay system and achieve maximum amount of harmony between the three Services. A decision was also taken by the Government that the future pays of the Armed Forces should be linked with civil pays. Based on these parameters and guided by the Post War Pay Code of the British Armed Forces, the Post War Committee recommended a remuneration system based on the following equations  [15]  :- (a) Service officers should broadly receive equal treatment with police officers. (b) A fully trained infantry soldier with three years service was equated with a semi-skilled worker who in turn was equated with an Able Seaman of the Navy and the juniormost Leading Aircraftman of the Air Force. Comparison of Officers. The closest comparator to Defence Services officers was identified as the Police as both wore a similar uniform due to the fact that the Indian Police was manned by mostly retired British Army Officers in the past. This relativity had no other logic with regard to job content. The same continues till date, much to the detriment of the Service officers pay scales. In establishing this relativity, it was agreed that the end of the Maj scale should not exceed the end of the Senior Time Scale of the Police in which the SP was placed, thereby establishing a linkage between the two. The next link in the Police then was the DIG. The Service representatives sought a linkage of the DIG with the rank of Lt Col. However, DIG was finally placed between the service ranks of Lt Col and Col. One of the factors in establishing this linkage was that the three pillars of administration, namely the DIG of a Range, the Commissioner of a Division and the Commander of a Military Di strict (of the rank of Colonel) had near identical years of service, were of approximately the same age and required to socially interact with each other. The Raghuramaiah Committee Report. Consequent to the Second Pay Commissions Report in 1960, a Departmental Committee, headed by Shri Raghuramaiah, examined the pay and allowances of the Armed Forces. It stated that  [16]  :- The Service representatives felt that pay scales approximating to the scales prevalent on the civil side were preferable to the existing pay structure, but that a revision would be such a complex and lengthy process that it was not practicable at the present juncture. In view of these practical difficulties, we decided that the present pay structure might be retained until such time as the Government finds it convenient to carry out a detailed review. Initiation of Major Changes in Cadre Structure by IAS IPS. As the benefit of a review of their conditions of service and pay scales could not be done, the Armed Forces emerged into the post second Pay Commission scene with a arithmetical revision of their pay and allowances. At this stage the Civil Services, especially the IAS and IPS, initiated major changes in their cadre structure. A Selection Grade was introduced in the IPS, between the SP and DIG. This grade was equated to the service rank of Col and pressure was built up for revision of DIGs pay scale. By 1969, the DIG had overtaken the rank of Col, and started drawing relativity with the ranks of Commodore and Brigadier, thereby lowering the status and relativity of the Armed Service Officer vis a vis the Police. The Third Pay Commission. In early 1970, the Government while announcing the formation of the 3rd Pay Commission, for the first time, entrusted the task of reviewing the pay and allowances of the Armed Forces to a Pay Commission and not to a Departmental Committee. However, there was a major difference between the terms of reference as applicable to the Armed Forces and that of the civilians. In the case of the Armed Forces, the Commission was not asked to make recommendations on the conditions of service but take them as given. This difference was prominently highlighted by the Commission in their report. On the question of the presentation of the Services case, the Commission was of the view that the service personnel should have the liberty to represent their case directly before them like civilian employees. But this request to the Ministry of Defence was turned down on the grounds that the requirement of Armed Forces discipline would not permit such an approach. Thus the three S ervices could not explain their case directly to the Pay Commission. As a result, many of the anomalies injected by earlier Committees remained uncorrected  [17]  . Status of Officers. The main thrust of the services was to seek parity in pay scales with the IAS. The Third Pay Commission was of the view however that the officer cadre of the Armed Forces was an omnibus group of individuals of varying disciplines, status and job responsibilities. Whilst there would certainly be some categories, though difficult to identify, who could claim parity with the IAS, the 60,000 strong Armed Forces officer cadre could at best be compared with the Class I officers cadre which had a similar disparate composition. Parity with IAS was therefore not accepted and the existing relativities were retained  [18]  . Expert Cell. The Ministry of Defence now created an Expert Cell comprising the Chairmen of the three Services Pay Cells, a Joint Secretary and an Additional Financial Adviser. The Expert Cell was asked to scrutinise the Memorandum of each Service and give their own views to the Pay Commission. Unfortunately no agreement could be reached between the Service Members on the one side and the Ministry of Defence on the other. Eventually a report was submitted only by the Service Members. This resulted in the impact of their report being lost and the Third Pay Commission had to seek views of Ministry of Defence seperately. Compensation for X Factor. In the British Armed Forces Pay Structure, the X factor compensated for the uniqueness and distinct disadvantages of service life. Service Headquarters sought the extension of the X factor to the Indian Armed Forces. The Third Pay Commission examined the advantages and disadvantages of Service life, considered that the former outweighed the latter and concluded that there was no justification for the X factor. One of the advantages of naval life taken into consideration was the opportunity for naval personnel to visit distant foreign countries at Government expense  [19]  . Formulation of Rank Pay. The third pay commission also crafted a rank pay out of the existing pay for defence personals. This was to differentiate the pay from Captain to Brigadier in a running pay band. It was specified by the pay commission that the rank pay was part of basic pay for calculation of all emoluments for consideration of status. The successive pay commissions continued with the same. But in the sixth pay commission, when the rank pay was abolished, the pay of all service personals was calculated erroneously as rank pay was not taken into consideration. This created a major anomaly. Research of XLRI Jamshedpur for sixth pay Commission in Estimating cost of Benefits For Armed Forces to government Incongruous Deductions XLRI Jamshedpur was tasked by the sixth pay commission to estimate cost of benefits of all government servants including defence personals. In their estimate, mundane things like loans for housing, car computer, canteen facilities, medical care etc were taken into consideration to calculate the cost of living of defence personals. The picture thus pasted was a very rosy one. The problems faced by defence personals in form of frequent transfers, separation from family, lack of stable education for wards of defence personals were not taken into consideration. Comparison with IPS, PMF and Other gp A services The sixth pay commission compared the Brigadier rank of Defence forces with DIG of the IPS. This comparison was wrong because the DIG was placed between Lt Col Col in all previous comparisons. The DIG wore the insignia of Ashoka a Star till early 1970s but later it was changed to Ashoka three Stars. On being questioned, it was clarified by the MoH that police ranks wear Silver Stars which was different from the Brass Stars of the military hence no comparison was possible. The Commission also used the PMF for comparison with the Armed Forces forgetting that PMFs are not Group A services. A service is considered Group A service only if at least 80 % of its employees hold ranks equivalent to Jt Secy above. The same was utilized by the bureaucracy in creating a rift between the Armed Forces the CPMFs quoting the problems faced in empowerment of CPMFs whenever the injustice faced by the Armed Forces were highlighted. Delinking the rank pay from the basic pay caused a major setback to the pay parity of Armed Forces with the other Group A services. Certain ranks with a higher pay scale till fifth pay commission turned up with a lower grade pay after the Sixth Pay Commission. In a noteworthy judgment, the Supreme Court of India directed that Rank Pay forms part of Basic Pay. The same was prayed by the Govt of India to reconsider the same is still pending. Comparison with Defence Support Services It must also be brought to light that Defence Support Services like Defence account services, Ordinance Board Services etc which are primarily existing for supporting the Armed Forces now enjoy a better pay scale that what is enjoyed by the services they serve. Also the promotion rate is much faster with an officer making it to Jt Secy level in 16 yrs while a equivalent Maj Gen makes it after almost 32 yrs of service. The Govt Doctors also have a faster promotion rate due to the MACP scheme but the same could never be implemented for Armed Forces doctors due to the acute disparity they would cause. PART IV WARRANT OF PRECEDENCE PRESENT CONDITION Successive Lowering of Status The status of Armed Forces Officers was lowered after each war as it was perceived by the civil society that the image of Armed Forces Officers was augmenting the political as well as bureaucratic class found itself threatened by the same. Analysis Effects of 6th pay commission to Include Financial Effects The pay commission was near sighted in determining the grade pay of Armed Forces Officers but when faced with a large amount of criticism, it delinked grade pay from status clarified that grade pay was only for determining inter services seniority. This was a knee jerk reaction but the damage was done. The grade pay differences was not only to be used to determine the seniority for all practical purposes but also determined the amount of Entitlements Benefits for all personals. This caused a major Financial Loss to all personals including loss of Social Standing among peers. Misinterpretation of the Warrant by Vested Interests The Warrant of Precedence shows Jt Secy to the GOI to be equivalent to Maj Gen. The official warrant does not cover the lower ranks. This was taken as a guide map by vested interests in equating all civil posts of IG police similar posts with a Maj Gen. In view of the above, it must be stated that very few posts are equivalent to Jt Secy to the GOI posts like IG police of a state is not equivalent unless empanelled by the GOI. These minor rules are not known by a large number of people are being used by some persons for their advantage. The Economic Boom the Present IS Situation The boom in the economy added to the aspiration of all persons including that of the Armed Forces. The present IS situation also increased the commitments lead to further increase in difficulties faced by the Defence personal. The same was not adequately compensated by the successive pay commissions or the government thus causing a steady decline in their strata in the society. Status as Perceived by the Society In the present society where the visible factors of money power are taken as guidelines for deciding the Social Standing of a person, the persons of Armed Forces take a beating. This has caused a visible change in the social environment has also affected the intake of officers in the Armed Forces. This of status has even affected the parity which is perceived by the civil society which can be seen from various agencies intake of ex-servicemen. In a recent UCO bank intake, the post of Security Officer was open to Commissioned Officer in Army (Captain)/Navy (Lieutenant)/Air Force (Flight Lieutenant) and to Any officer in the rank of Inspector (Executive)/Inspector (GD) from Para-Military forces like BSF, CRPF, ITBP, CISF etc. Shortage of Officers in the Armed Forces The Armed Forced are facing a acute shortage of officers in all three services. The shortage of officers in the Army is around 11,500 and in the Navy, the shortage is around 1606. The numbers which are less in Air Force is around 1342. This shortage is causing serious hamper in the operational efficiency of the services the trend need to be arrested at the earliest. Noteworthy Judgment Rank Pay Judgment Maj Dhanapalan case are major judgments of Honorable Supreme Court of India stating rank pay forming part of basic pay for all intent purposes. The Supreme Court slamming the union for treating Armed Forces personnel like beggars in respect of emoluments and pension asking authorities to adopt a more humane approach towards those bravely defending the countrys borders. Treatment of Veterans by Civil and Military The agenda of One Rank One Pay is present in the election manifesto of most of the National parties but no party in power has done anything on the same except giving lip service. The ex-servicemen returning their medals to the President of India was a day of national shame but no concrete steps have yet been taken to meet the demands. PART V LACK OF INTENT AND ENDEAVOR CERTAIN POSITIVES Approach of Govt to Incl Politicians and Civil Bureaucrats The apathy towards Armed Forces was well observed when the Committee of Secretaries formed to look after the anomaly of Sixth Pay Commission was formed without a military member and established more anomalies in its verdict. The Group of Ministers formed after the same to look into possible anomalies has not given any verdict even after a year of its formation. When the veterans demanding One Rank One Pension marched toward the Rashtrapati Bhavan for returning their medals, the President who is the Supreme Commander of Armed Forces did not even feel it important to meet them and assigned a Joint Secretary to receive the medals in her behalf. Negating the Effects of AVC Commission AVC Commission lowered the intake service for the rank of Captain to two years and that of Major to six years. This was done to increase the satisfaction level of the officers of the three services. The same effect was reversed by the Sixth Pay Commission in which the grade pay of all ranks Captain onwards was lowered such that now the Major equaled the Captain of the pre-AVC Commission days. It must be noted here that the Major of post AVC Commission is not even authorized the Majors Accommodation he possesses in a military station but now being equal to a erstwhile Captain, is authorized only the Captains Accommodation. This may not be a area of concern in a pure military station, but causes major embarrassments in a mixed station where the status has declined substantially. Similar problems exist for all military ranks. The Working of Mil Machinery Before the

Colin Powell :: essays research papers

My Written Report is a Short Biography of Colin Luther Powell. He was born on May 5, 1937 in Presbyterian Hospital. He was born, and grew up, in the South Bronx, New York. There was a big influence of drugs and gangs where Powell lived but, he seemed to steer away from all of that (source 1, page 23). Powell's parents were immigrants from Jamaica. His mother's name is Muad Ariel McKoy. In Jamaica the McKoy fammily watched over sugar plantations. She came to America with her mother (Colin's grandmother). Powell's father's name is Luther Theophilus Powell. In Jamaica the Powell families were peasant farmers. Muad and Luther while in New York not in Jamaica (source 1, page 20, 21). Colin Powell is a smart man. Surprisingly when he was in fourth grade he was in the slow class. When he attended Junior High School, he went to an all male school. He did well academically but he was over looked by his parents because his sister, Marilyn Powell, always did better. He attended Morris High Scho ol in 1950. He was good in high school; he never got into any fights or any sort of trouble. He completed High school in 1954 (source 1, page 29, 30, 32). Powell applied to two colleges City College of New York (CCNY) and New York University (NYU). Both accepted him but he went to CCNY because it only ten dollars a semester as opposed to seven hundred and fifty dollars a semester at NYU. Powell majored in Engendering. He finished college in 1958 (source 1 pages 32, 36). While in college Powell joined the Recruit Officer Training Corps (ROTC). Powell said he joined ROTC because of the discipline and "The sense of comradery among a group of young men who were similarly motivated. Maybe it was the uniform." Another reason he said he joined is because of the association with the military [source 2 (interview page 1) (biography page 1)]. While Powell was in ROTC, he was in the Pershing Rifles. The Pershing Rifles showed that a cadet was more serious about ROTC than a regular ca det. The Pershing Rifles had to stay in ROTC their whole college career. They were distinguished through a yellow wrap worn on their right shoulder (source 1, page 40). In 1987 Powell was the Nation Security Advisor to Ronald Regan. Two years later in 1989 he became the first black officer and the youngest officer to hold the nation's highest military office, the Chairman of Joint Chiefs of Staff.

Transformation: Randle McMurphy & Patients Essay -- Essays Papers

Transformation: Randle McMurphy & Patients He waltzed into the ward and introduced himself to every patient as a gambling man with a zest for women and cards. Randle P. McMurphy, a swaggering, gambling, boisterous redheaded con man, arrived at the ward from the Pendleton Work Farm. He was sentenced to six months at the prison work farm, but pretended to be insane in order to obtain a transfer to the hospital because he thought it would be more comfortable than the work farm. Bromden senses that there was something different about this new patient. After his first experience with the excruciating routine of the Group Meeting, McMurphy tells the patients that Nurse Ratchet is a genuine â€Å"ball-cutter.† The other patients tell him that there is no defying Nurse Ratched because, in their eyes, she is an all-powerful force. True to his nature as a gambling man, McMurphy makes a bet with the other patients that he can make Ratched lose her temper. At first, the confrontation between Ratched and McMurphy provides some humorous entertainment for the other patients. However, McMurphy’s confrontation soon becomes their confrontation as he draws them into the conflict by encouraging their rebellion. The success of his bet hinges on a failed vote to change the television schedule so they can watch the World Series. The Series was on television during the time allotted for cleaning chores. McMurphy and the other patients staged a protest by sitting in front of the blank television in...
