Sulfur recovery processes Essay Example | Topics and Well Written Essays - 750 words

Sulfur recovery processes - Essay Example gas treatment system, where the effluent gases that remain from the purification process are used to oxidize sulfur into sulfur dioxide, instead of being released to the atmosphere to cause pollution. Most significant is that this process yields high quality sulfur, making it a good source of this valuable chemical (Kohl & Nielsen, 1997). However, the air pollution controls that have been put in place have made the Claus process even more expensive, since some installations that prevent air pollution have to be made, despite the fact that they may not be economical at all. The problem of Claus Process is added to, by the fact that it is unable to fully convert hydrogen sulfide into elemental sulfur, due to some equilibrium limitations. Therefore, no matter how well the emission of sulfur compound is controlled, the process ends-up releasing relatively high quantities of the air pollutant than is actually acceptable (Kohl, 1997). Thus, most of the times, the process requires to be supplemented with specific processes meant to remove the sulfur residue, which ensures that any excess sulfur emission from the process is cleaned-up. Claus process occurs in two forms, referred to as the straight-through process and the split-flow process. The processes are differentiated by the fact that, while in the straight-through process gas is fed through the reaction furnace, it is fed directly into the major catalytic reactor through bypassing the furnace, in the split-flow process (Kohl & Nielsen, 1997). The choice of the process to be used between these two sulfur purification processes depends on the content of hydrogen sulfide in the gas to be purified, and whether the gas contains hydrocarbons. If the gas to be purified contains hydrocarbons, then, the straight-through process is opted for, while the split-flow process is applied where the gas does not contain large quantities of hydrocarbons (Kohl, 1997). There are some fundamental aspects of the Claus process that should

Treason, Terrorism and Wartime Criminal Justice Essay Example for Free

Treason, Terrorism and Wartime Criminal Justice Essay In the history of the United States the acts of treason, terrorism and criminal justice during times of war have taken on various forms. From the Sedition Act of 1798 to the current war on terror, the Constitution and its amendments have been challenged to ensure national security. To understand this we must first look at what treason and terrorism are and the effects they have had in the reduction of civil liberties during times of war. Treason   Treason is defined as: â€Å"The betrayal of ones own country by waging war against it or by consciously or purposely acting to aid its enemies. †Ã‚   (Wehl, 1950) Under Article III, Section 3, of the Constitution, any person who levies war against the United States or adheres to its enemies by giving them â€Å"aid and comfort† has committed treason within the meaning of the Constitution. The term aid and comfort refers to any act that manifests a betrayal of allegiance to the United States, such as furnishing enemies with arms, troops, transportation, shelter, or classified information. If a subversive act has any tendency to weaken the power of the United States to attack or resist its enemies, aid and comfort has been given. The Treason Clause applies only to disloyal acts committed during times of war. Acts of disloyalty during peacetime are not considered treasonous under the Constitution. Nor do acts of Espionage committed on behalf of an ally constitute treason. For example, Julius and Ethel Rosenberg were convicted of espionage, in 1951, for helping the Soviet Union steal atomic secrets from the United States during World War II. The Rosenbergs were not tried for treason because the United States and the Soviet Union were allies during World War II. â€Å"Under Article III a person can levy war against the United States without the use of arms, weapons, or military equipment. Persons who play only a peripheral role in a conspiracy to levy war are still considered traitors under the Constitution if an armed rebellion against the United States results. After the U.S. Civil War, for example, all Confederate soldiers were vulnerable to charges of treason, regardless of their role in the secession or insurrection of the Southern states. No treason charges were filed against these soldiers, however, because President Andrew Johnson issued a universal amnesty.† (Smith, 1956) The crime of treason requires a traitorous intent. If a person unwittingly or unintentionally gives aid and comfort to an enemy of the United States during wartime, treason has not occurred. Similarly, a person who pursues a course of action that is intended to benefit the United States but mistakenly helps an enemy is not guilty of treason. Inadvertent disloyalty is never punishable as treason, no matter how much damage the United States suffers. As in any other criminal trial in the United States, a defendant charged with treason is presumed innocent until proved guilty â€Å"beyond a reasonable doubt†. Treason may be proved by a voluntary confession in open court or by evidence that the defendant committed an â€Å"overt act† of treason. Each overt act must be witnessed by at least two people, or a conviction for treason will not stand. By requiring this type of direct evidence, the Constitution minimizes the danger of convicting an innocent person and forestalls the possibility of partisan witch-hunts waged by a single adversary. Unexpressed seditious thoughts do not constitute treason, even if those thoughts contemplate a bloody revolution or coup. Nor does the public expression of subversive opinions, including vehement criticism of the government and its policies, constitute treason. The First Amendment to the U.S. Constitution guarantees the right of all Americans to advocate the violent overthrow of their government unless such advocacy is directed toward inciting imminent lawless action and is likely to produce it (Brandenburg v. Ohio, 395 U.S. 444, 89 S. Ct. 1827, 23 L. Ed. 2d 430 [1969]). On the other hand, the U.S. Supreme Court ruled that the distribution of leaflets protesting the draft during World War I was not constitutionally protected speech (schenck v. united states, 249 U.S. 47, 39 S. Ct. 247, 63 L. Ed. 470 [1919]). Because treason involves the betrayal of allegiance to the United States, a person need not be a U.S. citizen to commit treason under the Constitution. Persons who owe temporary allegiance to the United States can commit treason. Aliens who reside in the United States, for example, can commit traitorous acts during the period of their domicile. A subversive act does not need to occur on U.S. soil to be punishable as treason. For example, Mildred Gillars, a U.S. citizen who became known as Axis Sally, was convicted of treason for broadcasting demoralizing propaganda to Allied forces in Europe from a Nazi radio station in Germany during World War II. â€Å"Treason is punishable by death. If a death sentence is not imposed, defendants face a minimum penalty of five years in prison and a $10,000 fine (18 U.S.C.A.  § 2381). A person who is convicted of treason may not hold federal office at any time thereafter.† (Chapin, 1964) Terrorism Terrorism is defined as: â€Å"The unlawful use or threat of violence, especially against the state or the public as a politically motivated means of attack or coercion.† (Davenport, 2009) When we speak about terrorism, we initially mean transnational terrorism, which takes the form of the violent conflict between two or more different states. If we take terrorism as violation of certain social norms, the norms of what state should we take into account? On the one hand, terrorism directly violates the social norms of the society against which it is directed. On the other hand, terrorism becomes an acute response to the threats, under which the social norms of the terrorist state may appear. With the growing threats of terrorist attacks, numerous attempts have been made to explain the causation and roots of terrorism. There are several political, economic, and psychosocial theories which explain what terrorism is. The notion of terrorism has been discussed from the viewpoint of different disciplines and from various theoretical perspectives. Terrorism has been depicted more in political and social, rather than criminological terms. There have not been too many attempts to link terrorism to crime. This is why we still lack profound understanding of terrorism’s causation. Research has not produced any new theories which would explain terrorism. As a result, we can only utilize the existing well known crime theories to explain the notions and the roots of terrorism. The traditional picture of modern terrorism implies that terrorism has mainly Islamic roots. The extreme conservatism of the Islamic world and its reluctance to become a part of the worlds technological revolution may also serve the cause of terrorism. Rapid technological change changes the way institutions relate to one another. Change produces new norms, and new values. Those socialized to the old norms take time to adapt, and this ‘time lag’ results in the normative confusion between the old and the new societal values. (Laufer Adler, 1998) When such changes expand beyond the borders of one state and involve whole nations and continents, there will always be those who would refuse to conform to the new norms. The transition from the older to the newer norms actually causes significant stress onto the societal conscience. Terrorism is the ultimate act of opposition against the imposed implementation of the new norms. As states use terrorism to prove their social or political position, they defend their social norms and violate the norms of other states. Trying to determine the roots of terrorism, we must look at the so-called irrationality of terrorism†. This hypothesis stems from the theory of rational choice. Although it is difficult to deny that terrorism is a rational choice activity, in many instances rational choice remains irrelevant to explaining terrorism as a crime. This is further proof of the fact that we need one unified objective theory which would draw the terrorism cause in logical terms. On the one hand, terrorism as a crime is irrational in responsiveness to incentives. (Caplan, 2005) This factor determines the willingness of a person to commit a crime: the better the incentives are, the more inclined towards a crime a person will be. Moreover, rational choice suggests weighing all possible alternatives in choosing the tactics of specific crime. â€Å"The same holds for suicidal terrorism. Groups do not adopt suicide tactics for their own sake. They adopt them because they work†. On the other hand, we cannot explain terrorism within the theoretical framework of narrow self-interests which is integrally linked to traditional rational choice theory of crime. (Wilson, 2005) â€Å"Suicidal terrorism is far stronger counter-example to narrow self-interest. From a non-evolutionary viewpoint, it is impossible to reconcile the two. No matter how much you receive for your services, it does you no good if you are not alive to consume anything. Furthermore, if you get paid first and die later, there is an end-game problem. A selfish agent would take the money, then do everything in his power to back out† (Caplan, 2005). â€Å"Terrorism is first and foremost a criminal matter†. However, criminologists still fail to produce a relevant and explicit theory about terrorism as a crime. We possess sufficient knowledge about terrorism as a political, economic, or social phenomenon, but for some reason we keep forgetting that terrorism is a crime, and we primarily perceive as a crime with its peculiar characteristics. We will never be able to develop sound anti-terrorism preventive measures, if we lack understanding of terrorism from the criminological perspective. (Hamm, 2007) We must be aware of what causes terrorist crimes, what justifies them, and how we can deal with terrorist violence. Our primary task is to shift the emphasis from political to criminological perspective of terrorism. We must ultimately recognize that prevalence and incidence of terrorism requires criminological re-consideration. The new crime theory of terrorism must be multifaceted, and should link criminology of terrorism to its political dynamics and environmental contingencies. (Laufer Adler, 1998) Wartime Criminal Justice Historically, Americans risk losing civil liberties in wartime. Two risks to civil liberties arise out of war situations, first that under the guise of emergency, powers concentrated into the hands of government agents are misused, and second, that when the emergency ends, liberties formerly enjoyed are permanently eroded. The Constitution divides war powers between the Congress and the President.   This division was intended by the framers to ensure that wars would not be entered into easily: it takes two keys, not one, to start the engine of war. The Constitutions division of powers leaves the President with some exclusive powers as Commander-in-Chief (such as decisions on the field of battle), Congress with certain other exclusive powers (such as the ability to declare war and appropriate dollars to support the war effort), and a sort of twilight zone of concurrent powers.   In the zone of concurrent powers, the Congress might effectively limit presidential power, but in the absence of express congressional limitations the President is free to act.   Although on paper it might appear that the powers of Congress with respect to war are more dominant, the reality is that Presidential power has been more importantin part due to the modern need for quick responses to foreign threats and in part due to the many-headed nature of Congress. A brief survey of American history indicates that virtually every war has been accompanied not only by necessary restrictions on individual freedoms, but on overreactions, often hysterical, that has unnecessarily curtailed the liberty of Americans. The undeclared naval war by Britain and France on the fledgling United States in the 1790s led President Adams’ Federalist controlled Congress to pass the â€Å"Alien and Sedition Laws†Ã¢â‚¬â€clear violations of the First Amendment. Prosecutions under the law, soon after repealed, were politically motivated. President Lincoln suspended the writ of habeas corpus in thousands of cases during the Civil War. Although historians have granted the necessity and even the restraint of these acts, the Supreme Court repudiated this unilateral presidential power after the War ended. A World War I sedition law made criticism of the military draft a crime. Sedition prosecutions stifled free speech. In reaction, the ACLU (American Civil Liberties Union) was formed and in a series of landmark cases, the Supreme Court strengthened First Amendment freedoms, limiting the ability of government to stifle unpopular political expression. Fear of Bolsheviks in post-World War I turmoil, a deadly Wall Street bombing, and assassination threats in 1919 led to the â€Å"Palmer Raids†Ã¢â‚¬â€round-ups of thousands of people around the country, mostly leftist or pro-labor, organized by J. Edgar Hoover under the authority of Attorney General A Mitchell Palmer. More than a hundred-thousand Japanese-Americans were interned for the duration of World War II in a tragic overreaction to the Pearl Harbor attack, a move upheld by the Supreme Court. President Roosevelt authorized national security wiretapping and eavesdropping on his authority, a necessary action that led to later abuses that were curbed by the Foreign Intelligence Surveillance Act (FISA). During the Korean War, President Truman nationalized the steel industry in order to break a strike that threatened war production. The Supreme Court swiftly ruled that this was an unconstitutional extension of the president’s war powers. The longest and most severe threat to civil liberty was the rise of the â€Å"national security state† for at least half of the twentieth century in an effort to thwart the real threats of fascism, Nazism, and expansionist Soviet communism under Stalin. Fascism and the Axis Powers were defeated both by military victories in World War II and by post-war assistance that painstakingly built constructed democratic regimes in Japan, Germany and Italy. â€Å"The long struggle to contain communist global expansion, warped American politics and justice in the 1950s, with political trials, loyalty oaths, Sen. Joseph McCarthy witch hunts (which missed real Soviet spies), artists’ blacklisting, local police department ‘red squad’ snooping, CIA spying on Americans within the country, FBI wiretapping Martin Luther King, Jr. And civil rights leaders, and a climate of political fear that equated a belief in racial equality or other liberal opinions with communism by the FBI.† (Stone, 2005) The anti-Vietnam War protests of the 1960s produced repressive political crimes and political trials, which carried over into the wiretapping abuses of the Nixon Administration resulting in the president’s resignation under threat of impeachment. After these emergency periods passed, repressive laws were typically repealed or declared unconstitutional, and excessive law enforcement behavior was curbed. The nations commitment to free speech rebounded, usually rather quickly, and sometimes more robustly than before. A Congressional report declared that the Sedition Act of 1798 had been passed under a mistaken exercise of power and was null and void. The Sedition Act of 1918, which was repealed two years later, helped give birth to the modern civil liberties movement. And in 1976, President Ford formally prohibited the C.I.A. from using electronic or physical surveillance to collect information on domestic activities of Americans, and the new F.B.I. director, Clarence Kelly, publicly apologized for F.B.I. abuses under J. Edgar Hoover. (Sofaer Williams, 2002) In summary, we see how acts of treason against the United States have taken on different forms. If an act can weaken the power of the United States to attack or resist its enemies, aid and comfort has been given, and thus treason has been committed. Terrorism has evolved both in complexity and with technology. It can take on domestic and international forms and is the ultimate act of defiance against a society. Politics and religion feed the terrorists’ fervor and with the advancements in explosives, even suicide bombers pose a significant threat. As terrorism and treason have evolved, so too have the responses to those acts. From the Sedition Act to the Patriot Act, these responses have been controversial but necessary to ensure the safety of our nation. Many think it not only inevitable but entirely proper that liberty give way to security in times of national crisis. The Founders warned us about the risk, and equipped us with a Constitution designed to deal with it. References Caplan, B. (2005). Terrorism: the relevance of the rational choice model.

Synthesis and Characterization of K2[Ni(CN)4] , K3[Fe(C2O4)3] and Cu(acac)2 Complexes :: Lab Report

Synthesis and Characterization of K2[Ni(CN)4] , K3[Fe(C2O4)3] and Cu(acac)2 complexes(IV , V and VI) with different structures and Properties 1. Introduction The aim of this experiment was to synthesize HgCo(SCN)4 , [Ni(en)3]S2O3 , NiCl2(PPh3)2 , K2[Ni(CN)4] , K3[Fe(C2O4)3] and Cu(acac)2 but only K2[Ni(CN)4] , K3[Fe(C2O4)3] and Cu(acac)2 were synthesized and explained in this report. Characterization was then done on each of the 3 synthesized complexes by obtaining their UV-Vis spectrum. The UV-Vis spectrum of each complex would identify different properties and would help to explain the observations made when they were synthesized (for example their colour and how they reacted). 2. Method Table 1: Synthesis of K2[Ni(CN)4] Amount of Reagents used Method Observations NiSO4 †¢ 7H2O : 6.00 g KCN : 3.01g In 20ml water NiSO4 †¢ 7H2O was dissolved and the solution containing KCN (dissolved in 7ml water) was added to the Nickel solution. This solution was filtered and the precipitate was washed with small quantities of water. This precipitate was added to the solution of KCN (dissolved in 3ml of water). This solution was heated and swirled so that the crystals that formed dissolved. It was heated again and left so that crystals started forming again. This solution was then placed in an ice bath to enhance crystallization and the crystals were removed by filtration. The water was removed by drying the crystals in the oven at 100 °C. A small amount of the sample was dissolved in water and the UV-Vis spectrum was obtained. Nickel (II) sulphate hexahydrate was used in place of heptahydrate. When the precipitate was added to the KCN solution, it turned dark red. As it was heated it darkened even more but as the crystals started forming the colour changed to a light red. As the crystals dried more its colour changed from light red-orange to a light yellow colour. These crystals were dissolved in water for the UV-vis spectrum. The solution was a yellow colour. Table 2: Synthesis of K3[Fe(C2O4)3] Amount of Reagents used Method Observations (NH4)2Fe(SO4)2 †¢ 6H2O: 5.03g To a solution of (NH4)2Fe(SO4)2 †¢ 6H2O (dissolved in 20ml water) 1 ml of sulphuric acid was added and stirred. The oxalic acid (dissolved in 25ml water) was also added and this combined solution was slowly heated to boiling, resulting in the formation of yellow iron(II) oxalate precipitate. The liquid was decanted and 15ml of hot water was added again to the precipitate, this was stirred and filtered. The precipitate (iron(II) oxalate) was transferred to another beaker and a potassium oxalate solution (dissolved in 10ml hot water) was added.

Characters of Sir Walter Elliot and Anne Elliot in Jane Austens Persua

The Characters of Sir Walter Elliot and Anne Elliot in Persuasion  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In Persuasion, by Jane Austen, there are many exceptional characters. Perhaps two of the most memorable are Sir Walter Elliot, and his daughter, Anne Elliot. These characters are well shaped and have something about them that transcends time and social class, enabling readers of the all ages, to feel they have something in common with them. Jane Austen has created a very silly, vain man with immense family pride in Sir Walter Elliot. Sir Walter is extremely proud of his good looks, his family connections and above all, his baronetcy. The reader is introduced to Sir Walter at the beginning of the novel. Immediately his family pride is seen and the reader cannot help but associate Sir Walter with the aristocracy known to Austen. A simple character sketch of him reveals much: Vanity †¦ was the beginning and the end of Sir Walter Almost unconsciously, the reader feels a strong dislike for a man who: considered †¦ beauty as inferior only to †¦ a baronetcy. Sir Walter’s pride and vanity is reinforced in many different ways: the way he acts in certain situations, his opinions of others, his dialogue, and others opinions of him. Sir Walter is a character who will always act in the same manner, no matter what situation he is involved in. Sir Walter uses his family name for authority and decision making. For example, when Lady Russell suggests economizing Sir Walter reacts: What! Every comfort of life knocked off!†¦even of a private gentleman. Another example is when Sir Walter leaves Kellynch Hall and is "prepared with condescending bows". In each of these examples, Sir Walter reminds others of his title, and that they are l... ...

The chosen geographics for this research is Greece. Chapter 5: Decision This chapter reviews the aims of the research followed by supplying the decision to the study. Chapter 2: Literature Reappraisal 2.1: Historical overview Concrete, typically a mixture of sand, crushed rock and cement day of the months back to ancient history when ruddy calcium hydroxide was used as a cementing constituent in doing concrete ( Leif Berntsson Satish Chandra, 2002 ) . This makes it clear that the current mixtures of concrete have evolved over the historic periods to provide assorted technology demands with the developments in scientific discipline and the inventions in technology as argued by Leif Berntsson Satish Chandra ( 2002 ) . A classical illustration for the development of concrete since the ancient history is the usage of concrete by Romans in 300 BC when they found that blending a pink sand-like stuff which was volcanic ash they obtained from Pozzuoli with their normal lime-based concretes resulted in a far stronger stuff. The history behind the usage of sum to do concrete mix day of the months back to every bit early as the early the Roman period when the Romans used advanced methods in fixing concrete mixes with different sum stuffs to accommodate the structural demands and strength. The classical illustrations for the above statement include the usage of lightweight sums as in the roof of the Pantheon, and embedded support in the signifier of bronze bars as argued by Leif Berntsson Satish Chandra ( 2002 ) . The engineering in concrete utilizing different sums every bit good as accounting for thermic and other physical qualities of re-enforcing stuffs to do concrete mixes that provide the coveted strength is apparent throughout history although the industrial revolution and the addition in the technology and the function of steel in the 20Thursdaycentury have increased the invention every bit good as developments around the engineering of doing the right concrete mix. Concrete is non merely a critical component in the civil structural applications but besides a cardinal component in many other applications environing the building concern doing it one of the of import and most sought after merchandise in the technology concern itself as argued by Fu-Tung Cheng and Eric Olsen ( 2002 ) [ 3 ] . This is of course because of the fact that concrete is non merely a constituent in the building of civil constructions but besides a design ingredient in make up one's minding upon the strength, truss and other physical elements that govern the stableness of a given edifice. This is besides justified in the statements of Leif Berntsson Satish Chandra ( 2002 ) . The definition of cement in technology footings refers to pulverize stuffs which develop strong adhesive qualities when combined with H2O. This makes it clear that the cementing action of volcanic ash that was used to do concrete by the Romans autumn under the cement. It is farther apparent that concrete is referred to as a composite edifice stuff made from the combination of sum and cement binder. From the above it is clear that the developments in the quality of cement and the innovation of Portland cement, gypsum plaster, etc†¦ have a direct influence on the development of the concrete engineering although the aggregative constituent of the concrete composing plays an every bit of import function in assorted mixes of concrete that serve a coveted intent as argued by Leif Berntsson Satish Chandra ( 2002 ) . Another component of greater significance to the development of concrete engineering in the recent old ages every bit early as the 1900s is the development of concrete boats during the 2nd universe war where the lightweight sum concrete played a critical function in the design and building of the ships itself as argued by Glenn A. Black ( 2004 ) [ 4 ] . It is besides interesting to observe that the importance of concrete has increased with the demand for refined and purpose specific concrete mixes where the function of concrete has been non merely to supply the structural support but besides the coveted strength at the needed physical conditions that is set in the given geographical location as argued by Glenn A. Black ( 2002 ) . The growing of the expanded clay and shale industry since the morning of the 20Thursdaycentury and the developments during the Second World War when the lightweight sum concrete utilizing clay and shale was used to build the war ships marked the accelerated growing of the usage of lightweight aggregative concrete as argued by Glenn A. Black ( 2004 ) . 2.2: Definition of lightweight sum In order to specify the lightweight sum – the subject under research in this thesis, it is indispensable to show the basicss environing the lightweight sum. Hence this subdivision foremost presents a brief research on sum, its function in building as portion of the concrete mix and so travel towards the nucleus subject ( i.e. ) the definition of lightweight sum. Aggregate is the footings used to jointly mention to the ingredients in doing a concrete mix that gives strength and texture to the overall concrete composing made of sand, cement and sum as argued by Glenn A. Black ( 2004 ) . Aggregate is the composite stuff of the concrete that is aimed to defy compressive emphasis doing it clear that the size, strength and weight of the aggregative stuffs are critical constituents for the overall efficiency of the concrete to pull off the compressive emphasis as argued by Glenn A. Black ( 2004 ) . The modern twenty-four hours concrete utilizations Portland cement as the cementing component and the sum that is held together by the cement and H2O to plan concrete for different grades of strengths, lastingness, heat & A ; sound insularity, and H2O stringency as argued by Glenn A. Black ( 2004 ) . This makes it clear that the sum is the critical constituent of the concrete that attributes to observe merely the strength and quality of the concrete but besides dictates the nature of the applications and the extent to which invention in technology can be taken to. The cardinal physical quality of the sum is the compressive strength that it can back up for a given composing. The lightweight sums that are researched in this study typically attribute to up to 80 lbs per square inch which is used chiefly applications that demand lightweight concrete by virtuousness of the placement or for the support, insularity etc. specific gravitation is another critical component in depicting the quality of sum as the specific gravitation off the substance is straight relative to its emphasis and squeezability factors as argued by Glenn A. Black ( 2004 ) . A typical combination and most popular in the building industry for the sum is the crushed rock and sand mix at different sizes and squeezability that are used in high demand building structural applications as argued by Glenn A. Black. Hence sum in concrete is defined as the constituent of concrete that attributes to the strength, lastingness, squeezability and insularity properties to back up the coveted building application. Lightweight Aggregate Glenn A. Black ( 2004 ) says â€Å"The term â€Å" Lightweight Aggregate † describes a scope of particular usage sums that have an evident specific gravitation well below normal sand and crushed rock which were at one clip used in about all concrete† . From the above it is clear that the lightweight sum is one of the critical elements that makes concrete flexible and various to do the overall structural design and specifications as to run into the building demands as argued by Leif Berntsson Satish Chandra ( 2002 ) . It is besides interesting to observe that the lightweight sum in the concrete that is made utilizing light weight stuffs besides provide an appreciable degree of squeezability every bit good as possess strength that can be defined based on the composing therefore doing it a versatile and cost effectual procedure in the production procedure itself. The scope of lightweight sum is extended in nature from highly light stuffs used for insularity and non-structural concrete all the manner to expanded clays and shales used for structural concrete. This makes it clear that the lightweight sum in the concrete is chiefly aimed to accomplish high degree of physical stableness and squeezability through efficaciously using the physical qualities of the aggregative stuffs. This is farther justified in the statements of Leif Berntsson Satish Chandra ( 2002 ) who argues that the lightweight sum in the concrete is a major measure towards invention in the field of technology itself. The strength and the air trapped in each single atom of the constituents of the aggregative stuffs are reciprocally relative to each other therefore doing it clear that in order to derive lightweight aggregate the sum of air trapped in the single atoms must be high therefore doing it clear that the strength of the concrete therefore obtained is low. The above relationship stated provides the counsel to guarantee the balance between the air trapped and the strength required in the concrete mix therefore doing the overall lightweight sum concrete customisable to run into the structural demands of the application on manus. Lightweight Aggregate Concrete Spectrum The concrete spectrum ensuing from the usage of the lightweight sum is highly diverse in nature runing from really lightweight sum concrete up to high strength sums dedicated for specific bespoke applications as argued by Glenn A. Black ( 2004 ) . The ace lightweights scope of aggregative concrete that are derived from Vermiculite and Perlite are the capable of presenting weights every bit low as 15 to 20 lbs per three-dimensional pes therefore doing it clear the application of lightweight sums in the technology concern provides a diverse scope of applications for concrete. The natural sums, Pumice and Scoria for illustration can be used to do concrete deliberation at approximately 25 to 30 lbs per three-dimensional pes and extended every bit high as 65 lbs per three-dimensional pes as argued by Glenn A. Black ( 2004 ) . Furthermore, the usage of coal clinkers and expanded shale, clay and slate sums produced utilizing rotary kiln method can present weights in a varying scope from 75 to 120 lbs per three-dimensional pes. Another popular production method for this scope of sums includes the sintering where the weights are delivered typically runing from 90 to 120 lbs per three-dimensional pes. The high terminal applications of aggregative concrete include the production of sums capable of presenting weights up to 150 lbs per three-dimensional pes utilizing the air-cooled scoria sums and the hard-rock sums such as sand and crushed rock and crushed rock, which produce conventional concretes as mentioned by Glenn A. Black ( 2004 ) . From the above it is clear that the sums that lie in the lower terminal of the weight that have lower compressive strength are used chiefly for insularity intents whilst those in the in-between spectrum are used for insularity and filling. The high terminal of the lightweight sum concrete spectrum are used in a broad scope of structural applications that demand high compressive strengths every bit good as efficient direction of weight as argued by Glenn A. Black. The concrete spectrum for the lightweight sum concrete is presented in the figure below Fig 1: Lightweight Aggregate Concrete Spectrum ( Beginning: Glenn A. Black ( 2004 ) ,Lightweight Concrete history, Applications and Economics,Indiana University ) 2.3: Economicss environing lightweight Aggregate Concrete The cardinal facets of Lightweight Aggregate Concrete that attribute to the economical and structural benefits derived through the structural applications utilizing LAC include the undermentioned 2.3.1:Fire opposition– Resistance to fire is one of the critical elements that is expected in concrete to guarantee that the fire opposition and the structural stableness of the civil construction is maintained through the usage of aggregative concrete as argued by John P. Ries and Thomas A. Holm ( 2006 ) [ 5 ] . The fire opposition of lightweight sum is higher compared to the typical concrete sum chiefly because of the fact that the aggregative stuffs composing the lightweight sum have lower thermic conduction, lower coefficient of thermic enlargement as argued by John P. Ries and Thomas A. Holm ( 2006 ) . The fact that the aggregative stuffs possess built-in fire resistant belongingss is the cardinal component that is emphasised and strengthened in instance of the lightweight aggregates where the aforesaid heat opposition belongingss help accomplish higher fire opposition. It is besides interesting to observe that the built-in fire stableness of sum is high and in instance o f the lightweight sum it is at a heat of over 2000 grades Fahrenheit. As it is stated in the â€Å"ACI 216 â€Å" Standard Method for Determining fire Resistance of Concrete and Masonry Construction Assemblies † , when slab thickness is determined by fire opposition and non by structural standards ( Goists, waffle slabs e.g. ) , the superior public presentation of lightweight concrete, will cut down the thickness of slabs ensuing in significantly lower concrete volumes† , ( John P. Ries and Thomas A. Holm, 2006 ) . From the above it is clear that the fire opposition belongingss of the lightweight sum straight contributes to the overall structural stableness and the decrease in the volume occupied by the concrete in the structural applications. This justifies the various nature of the lightweight sum therefore enabling it to be used in advanced structural applications as argued by John P. Ries and Thomas A. Holm ( 2006 ) . 2.3.2: Service Life of the Structure– The service life of the construction is another critical component that is used as step of economic usage in instance of measuring the concrete and the aggregative efficiency against the capital invested as argued by John P. Ries and Thomas A. Holm ( 2006 ) . Glenn A. Black ( 2004 ) further provinces that the lastingness of lightweight sum is high and the life of the constructions constructed utilizing lightweight sum prove to hold higher life lastingness. The historical grounds to warrant the aforesaid include popular constructions likeThe Port of Cosa –built about 273 B.C. where the builders used lightweight concrete made out of natural volcanic stuffs,The Pantheonthat was finished in 27 B.C that incorporates concrete changing in denseness from underside to exceed of the dome and the most popular Amphitheater, built in 75 to 80 A.D. where the foundations were cast as lightweight concrete utilizing crushed volcanic lava as argued b y John P. Ries and Thomas A. Holm ( 2006 ) . From the above statements it is apparent that the lastingness of the constructions designed utilizing the lightweight concrete is extended in nature. Looking into the more modern illustrations to warrant the service life of the lightweight sum used in concrete for building include the lightweight concrete ships built by the American Emergency Fleet Corporation during the First World War. The compressive strengths of the concrete used were in the scope of 5000 pounds per square inch ( 35 MPa ) obtaining a unit weight of 110 lb/ftJ ( 1760 kg/mJ ) or less utilizing the rotary kiln produced expanded shale and clay sum as identified by John P. Ries and Thomas A. Holm ( 2006 ) . The service of these lightweight concrete boats during the universe wars and their subsequent in the merchandiser ships warrant the lastingness and service life of the lightweight sum used in concrete building applications. Furthermore, the fact that the higher degree of air trapped in the atoms make the submergence efficient in instance of the marine applications makes lightweight sum as a natural pick for the Marine applications although the usage of lightweig ht concrete extends to commercial structural applications in many Bridgess across the United States of America where the structural efficiency and stableness on Bridgess that were deemed unserviceable due to hapless burden bearing capablenesss was improved through the usage of lightweight aggregative concrete as argued by John P. Ries and Thomas A. Holm ( 2006 ) . Furthermore, the critical component that attributes to the service life of the lightweight concrete is the heat opposition, opposition to environmental corrosion and its lightweight that reduces the burden on the construction doing its service life longer than the typical concrete applications. 2.3.3: Economic sustainability John P. Ries and Thomas A. Holm ( 2006 ) argue that the structural applications in the modern yearss are judged against the cost, functionality, aesthetics or a combination of these as argued by John P. Ries and Thomas A. Holm ( 2006 ) . This makes it clear that the costs associated with the building of the construction every bit good as the running costs associated with care, infinite and fix are the critical elements that attribute to the pick of a given concrete mix over another. The lightweight sum that is used in the LAC is higher in costs compared to the typical concrete mix as argued by John P. Ries and Thomas A. Holm ( 2006 ) . This is of course because of the demand to bring forth the concrete mix utilizing stuffs of alone physical belongingss and the extent of research and development involved with the overall design of the building application. Alongside, the cost is treated as the cardinal component in instance of commercial execution of building applications preponderant ly because of the fact that the step on the returns in footings of return on investing is attributable when compared against the costs associated with the building of the construction. John P. Ries and Thomas A. Holm ( 2006 ) say that although the capital involved with the building of lightweight constructions is high, the fact that the low care costs and costs associated with other back uping constructions during the buildings like the decrease in steel, girders and besides the decrease in the slab thickness will equilibrate the costs with the production of the LAC concrete mix itself. This farther justifies that the economic sustainability where the return on the investing and the optimal pick for building is accomplishable utilizing lightweight sum as argued by John P. Ries and Thomas A. Holm ( 2006 ) The statements of Glenn A. Black ( 2004 ) that the lightweight sum besides has the benefit of lower degree of care and negligible fixs associated due to its lastingness features farther justify that the effectivity of the lightweight sum in accomplishing economic sustainability is high. Hence the lightweight sum is extremely recommended in the building of critical structural applications like Bridgess and commercial edifice where the burden bearing is high and the infinite is a critical component to salvage costs. 2.3.3: Energy ingestion and energy nest eggs– The Energy Performance of Buildings Directive of the European Union is a classical illustration for the justification that the composing of the concrete and the belongingss of the constituents consisting the construction of constructing commercial and domestic contribute straight to the overall energy ingestion as argued by John P. Ries and Thomas A. Holm ( 2006 ) . This is farther justified in the statements of Sarah Gaventa ( 2006 ) [ 6 ] where the writer has justified that the concrete mix and the design of the overall construction to accommodate the structural demands have a direct impact on the energy ingestion. Alongside, the heat immune belongingss of the lightweight sum and the ability to pin down higher sum of air within the atoms consisting the sum further do the lightweight sum to be able to run into the warming and chilling demands in a given construction as argued by Sarah Gaventa ( 2006 ) . It is besides interesting t o observe that the energy public presentation efficiency in the edifice particularly in the West where a major part of the energy is used for heating intents justify that the concrete mix and the aggregative composing to do the concrete mix are critical for the successful energy nest eggs in the edifices as argued by Sarah Gaventa ( 2006 ) . The lastingness, stableness and other physical belongingss including the squeezability of an aggregative stuff property to the ability of the concrete used in the edifice to retain heat therefore cut downing the ingestion of energy for interior warming intents as argued by Sarah Gaventa ( 2006 ) . It is besides a good known fact that the decrease in the concrete denseness increases the thermic opposition therefore doing it clear that the lightweight sum will increase the thermic opposition due to the lower specific gravitation of the aggregative composing that reduces the denseness of the concrete used in the building of the construction. A typical illustration is the concrete denseness of 90lb/cubic pes will hold a opposition ( R value ) of 0.26/inch whilst the R value for a denseness of 135lb/cubic pes is about 0.10/inc therefore doing it clear the energy efficiency is greatly increased through the usage of lightweight sums as argued by John P. Ries and Thomas A. Holm ( 2006 ) . Chapter 3: Concrete Production 3.1: Overview The production of concrete mix utilizing the sum is achieved through the commixture of the sum, sand and cement with right sums of H2O to bring forth the concrete mix of the necessary strength. The concrete commixture is dependent upon the quality of the sum every bit good as the cement used to accomplish the coveted denseness, strength and squeezability of the concrete for the structural application. In this chapter a critical overview on the cement production followed by the production methods for lightweight sums is presented to the reader. 3.2: Cement Production The chief ingredient for the production of cement is limestone of changing chemical composings that are freely available in the preies as argued by Sarah Gaventa ( 2006 ) . The lime rock is processed and farther chemicals are added to derive the cement of the necessary strength and squeezability. The undermentioned explains the production procedure briefly The natural limestone of changing chemical combinations is foremost collected to fix the natural mix where the limestone is assorted with minerals of minerals incorporating Ca oxide, Si oxide, aluminum oxide, ferrous oxide, and Mg oxide. This mixture is prepared to a all right mixture which forms the natural mix for a typical Portland cement. This is so blended to organize the natural blend where the natural mix is formulated to a really tight chemical preparation to derive the coveted strength from the finished green goods of the cement as argued by Sarah Gaventa ( 2006 ) . The natural blending procedure is conducted in a manner where the comparative content of each oxide in the chemical composing is kept changeless throughout the production procedure in order to guarantee that the belongingss of the concluding merchandise is non altered. It is besides argued by Sarah Gaventa ( 2006 ) really little alterations to the Ca content in the natural mix may take to big alterations in the ratio of alite to belite in the cinder, and to matching alterations in the cement ‘s strength-growth features ( Sarah Gaventa, 2006 ) . This makes it clear that the effectual control of the natural mix is critical for the production of consistent quality cement to run into the demands of the structural application. The following phase is the preparation of the cinder where the blend natural mixture is put through a complex chemical reaction procedure in a big cement kiln with temperature increasing over the length of the cylinder as argued by Sarah Gaventa ( 2006 ) . The concluding merchandise of the procedure is called cinder which is the concluding merchandise of the cement produced in the solid signifier at the coveted chemical combination. This is so put through a cement crunching procedure where the cinder that is produced is assorted with little sums of Ca sulfate to crunch the cement to the desired coarseness in order to back up the structural application. Sarah Gaventa ( 2006 ) further argues that the major constituents that decide on the strength and quality of cement include the undermentionedCinderGypsumLimestoneBlast Furnace SlagThe Blast Furnace Slag is one of the critical elements in lending to the stableness of the chemical reaction in the cement kiln as argued by Sarah Gaventa ( 2006 ) . Another interesting component with the blast furnace scoria is the fact that the effectual usage of the scoria in the cement production procedure besides allows to command the specific gravitation of the cement when assorted with aggregative and H2O to organize concrete every bit good as the ability to make the coveted strength of the cement concrete through the right combination of limestone and gypsum. The schematic of the cement production procedure is presented in the fig 2 below. Fig 2: Cement production Schematic ( Beginning: hypertext transfer protocol: //www.cimnat.com.lb/Production/Model.gif ) 3.3: Sum production The aggregative production is the following critical component in the lightweight concrete readying as the lightweight sum is one of the major elements that must be produced at a higher degree of preciseness in order to guarantee the coveted degree of strength and specific gravitation are achieved as argued by John P. Ries and Thomas A. Holm ( 2006 ) . The rotary kiln method is a traditional method of production which is popular since 1946 as argued by Glenn A. Black ( 2004 ) . The procedure of the production involves the application of heat to shale, clay and slate under controlled conditions. The conditions include the force per unit area and other features that trigger chemical reactions in order to accomplish the preferable specific gravitation and denseness of the sum constituent which is so land to the needed coarseness as argued by Glenn A. Black ( 2004 ) . The sintering method every bit good as the rotary kiln method typically use the similar base natural stuff that comprise of a extremely silicious clay or shale that exhibits a bloating characteristic which is achieve through gas-forming minerals which release gas on exposure to the desired degree of heat as argued by Glenn B. Black ( 2004 ) . It is besides interesting to observe that the readying of the sum is dependent upon the extent to which the force per unit area and the external temperature is controlled that set the temperature-based chemical reactions as argued by Glenn A. Black ( 2004 ) .

Atomism - Pre-Socratic Philosophy

Atomism - Pre-Socratic Philosophy Atomism: Atomism was one of the theories the ancient Greek natural philosophers devised to explain the universe. The atoms, from the Greek for not cut were indivisible. They had few innate properties (size, shape, order, and position) and could hit each other in the void. By hitting one another and locking together, they become something else. This philosophy explained the material of the universe and is called a materialist philosophy. Atomists also developed ethics, epistemology, and political philosophy based on atomism. Leucippus and Democritus: Leucippus (c. 480 - c. 420 B.C.) is credited with coming up with atomism, although sometimes this credit is extended equally to Democritus of Abdera, the other main early atomist. Another (earlier) candidate is Moschus of Sidon, from the Trojan War era. Leucippus and Democritus (460-370 B.C.) posited that the natural world is comprised of only two, indivisible bodies, the void, and atoms. Atoms continually bounce around in the void, bouncing into each other, but eventually bouncing off. This movement explains how things change. The Motivation for Atomism: Aristotle (384-322 B.C.) wrote that the idea of indivisible bodies came in response to the teaching of another Pre-Socratic philosopher, Parmenides, who said that the very fact of change implies that something that is not either really is or comes into being from nothing. The atomists are also thought to have been countering the paradoxes of Zeno, who argued that if objects can be infinitely divided, then the motion should be impossible because otherwise, a body would have to cover an infinite number of spaces in a finite amount of time. Perception: The atomists believed we see objects because a film of atoms drops off the surface of the objects we see. The color is produced by the position of these atoms. Early atomists thought perceptions exist by convention, while atoms and the void exist by reality. Later atomists rejected this distinction. Epicurus: A few hundred years after Democritus, the Hellenistic era revived the atomist philosophy. Epicureans (341-270 B.C.) formed a community applying atomism to a philosophy of living a pleasant life. Their community included women and some women raised children there. Epicureans sought pleasure by getting rid of things like fear. Fear of gods and death are inconsistent with atomism and if we can get rid of them, we will be free of mental anguish.

Basic Parts of the Brain and Their Responsibilities

Basic Parts of the Brain and Their Responsibilities The scarecrow needed it, Einstein had an excellent one, and it can store a whole lot of information. What is it you say? Why, the brain of course.  The brain is the control center of the body. Think of a telephone operator who answers incoming calls and directs them to where they need to go. Similarly, your brain acts as an operator by sending messages to and receiving messages from all over the body. The brain processes the information it receives and ensures that  messages are directed to their proper destinations. Neurons The brain is composed of specialized cells called neurons. These cells  are the basic unit of the nervous system. Neurons send and receive messages through electrical impulses and chemical messages. Chemical messages are known as neurotransmitters and they can either inhibit cell activity or cause cells to become excitable.   Brain Divisions The brain is one of the largest and most important organs of the human body. Weighing in at about three pounds, this organ is covered by a three-layered protective membrane called the meninges. The brain  has a wide range of responsibilities. From coordinating our movement to managing our emotions, this organ does it all.  The brain is composed of three main divisions: the forebrain, brainstem, and hindbrain. Forebrain The forebrain is the most complex of the three parts. It gives us the ability to feel, learn, and remember. It consists of two parts: the telencephalon (contains the cerebral cortex and corpus callosum) and the diencephalon (contains the thalamus and hypothalamus). The cerebral cortex allows us to understand the mounds of information we receive from all around us. The left and right regions of the cerebral cortex are separated by a thick band of tissue called the corpus callosum. The thalamus acts as a telephone line of sorts, allowing information to get through to the cerebral cortex. It is also a component of the limbic system,  which  connects areas of the cerebral cortex that are involved in sensory perception and movement with other parts of the brain and  spinal cord.  The hypothalamus is important for regulating hormones, hunger, thirst, and arousal. Brainstem The brainstem consists of the midbrain and the hindbrain. Just as the name suggests, the brainstem resembles the stem of a branch. The midbrain is the upper part of the branch that is connected to the forebrain. This region of the brain sends and receives information. Data from our senses, such as the eyes and ears, are sent to this area and then directed to the forebrain. Hindbrain The hindbrain makes up the lower portion of the brainstem and consists of three units. The medulla oblongata controls involuntary functions such as digestion and breathing. The second unit of the hindbrain, the pons, also assists in controlling these functions. The third unit, the cerebellum, is responsible for the coordination of movement. Those of you who are blessed with great hand-eye coordination have your cerebellum to thank. Brain Disorders As you can imagine, all of us desire a brain that is healthy and functions properly. Unfortunately, there are some who suffer from neurological disorders of the brain. A few of these disorders include: Alzheimers disease, epilepsy, sleep disorders,  and Parkinsons disease.

The middle east - a hotbed of conflict Essay Example | Topics and Well Written Essays - 2000 words

The middle east - a hotbed of conflict - Essay Example Speaking from a truly global standpoint, Middle East has proven to be a linchpin as far as having a clear cut understanding of the Arab nations is concerned. This is because the entire Arab region is linked with severe problems left, right and center. These problems have taken place due to lack of cultural adherences, an improper infrastructure within the different nations that exist within the Middle East region, and an overall mistrust in each other’s issues and undertakings. It would be appropriate to state that the Middle East has become a hotbed for conflict to arise sooner rather than later. The same happens on a very proactive basis whenever the world’s stock prices fluctuate and whenever there are financial issues arising in the wake of the economic aspects taking place. The Middle East has been a conflict hotbed because the people, who matter the most, i.e. the governmental top heads and the like, have paid less heed towards the domains of their own people. All they have focused on is to exponentially increase their respective capitals and to double their relevant investment regimes . They have not emphasized on how bad the economic domains of their countries are or how they are coping up with the other countries within the region. A lack of a coherent strategy within the entire Middle East lays the basis for serious conflict to arise, and this is a very grave anomaly indeed.

NSB224 RESEARCH APPROACHES IN NURSING - Essay Example (2). The abstract is a very important paragraph of the article. The length of the abstract is based on the journal for which the article is written, and normally does not extend beyond 250 words. This makes precision in the use of words and coherence of the matter important elements of the abstract. It is written as a single paragraph without references, providing the substance of the article. From such a perspective of a good abstract, the abstract the article can be rated as good. (3) The introduction is usually a few paragraphs in length written with the purpose of introducing the issue being investigated by the article, the relevance of the issue to the health care services and nursing. The problem of debilitation associated with hemodialysis is clearly mentioned at the outset, though not easily identifiable, owing to the structure of the introduction, wherein a number of issues are brought in one after the other. The problem is of significance to nursing, as it is nursing care that is essentially involved in patients on hemodialysis recovering their functional abilities and improving their well-being. (3). The main purpose of the literature review is to provide an understanding of what is known on the health subject or health problem. In doing so it gives clarity to the deficits in the current understanding of the health subject and how the article contributes to enhancing the understanding of the subject or problem. A good literature review draws information from reliable sources like peer-reviewed journal articles and books on the subject. It does not just summarize the information from these resources, but critically evaluates the information and looks at the connection of the information provide by these resources with regard to the topic of the article. In this way the literature review links the information from the different sources, provides

Learing protfolio Essay Example | Topics and Well Written Essays - 1500 words

Learing protfolio - Essay Example We did majority of the work but he was the one on the limelight and this made him take all the success for himself and not acknowledging the team. He tried charming customers with his looks once the team disintegrated but he only received failure reports after that as only looks alone do not work to gain success. Research by (Judge, Hurst & Simon, 2009) indicates that success of leaders is an accumulation of different attributes from the physical appearance to the mental ability as well as their core self-evaluation which basically deal with the confidence level of the leader. What this means is that without all these attributes mentioned above which are integrate with team work, a leader cannot be successful. When a leader is unaware of the factors that make him or her successful, when failure come s along, the leader is unlikely to rise back to the success domain again as he took the success as purely a fundamental attribute. The other thing highlighted by the article by (Gino & Pisano, 2011) that is mentioned in the topic is that overconfidence is one of the main impediments of learning about success and failure as a leader. An overconfident leader tends to be overshadowed by biasness as well as the fundamental attribution error. This therefore leads them to failing to ask for guidance or assistance even when they are on the verge of plunging into failure. What these does is that is leads the organization into eminent failure and underperformance that they cannot recover from to reach their levels of success once again. The topic basically is full of advice on how a leader should behave and what attributes to consider and remember when they are successful so that they can use them in case of any failure. The tips on success depending largely on mental ability, physical attractiveness and self-evaluation will really come in handy in future when I will have a chance to be a leader or even now in case I am chosen as a group

Papers - Essay Example The payment gateway used at the time of completion of an online transaction normally involves World Wide Web and some times even wider range of technologies. There are a few transactions for which there is no need of any physical labor like access to premium contents on a web site, being a paid member of some of the web group or library, transferring money from one bank account to another but most of the other transactions include transportation of goods in at least some way. Interesting terms like e-tail or e-tailer are used to define online retailers these days. Almost every bid retailer has a presence on the internet and even the websites comparing prices of same product that available online from different vendors are present for the ease and comfort of the consumer. Referred to as business-to-business or B2B and the other that is conducted between business and a consumer also called Business-to-consumer or B2C. In a B2B, there can be predefined business parties or arbitrary parties involved over the internet whereas B2C is primarily practiced The National Privacy Policy for Australia says that any organization must not collect data until and unless it is important for the smooth functioning of the organization. Ebay appears to be following most of the underlying principles of national privacy policy for the country including Use and Disclosure, Data Quality, Data Security, Access and Correction etc. but I felt that there are a few fields which may not be essential for the smooth functioning of the organization and thus therefore not in accordance with the privacy policy. For example a phone number is one such field that you need to enter while creation of the account on eBay and that you need to verify. If a person chooses not to verify his phone number then he is required to verify his credit card which is even more sensitive

Multimedia and Design Essay Example | Topics and Well Written Essays - 1000 words

Multimedia and Design - Essay Example Norman (2007) reveals that it is particularly important that before we judge these people we try step into their shoes. Before allowing one to label this person, try imagining they are acting like so or saying those things they are saying. Maybe this person always keeps to him/herself because s/he is uncomfortable around others, they just are not used to conversing with people hence they are a little cold, or most probably, they were not feeling well at the particular time you encounter them. We need to put ourselves on the receiving end, as in being treated the way we may be treating these people. It is necessary to note this before saying anything to the other person. It is definite that you would be pretty hurt if a stranger or someone you are not familiar with said something mean to you because you did not look or sound or act to their expectations or anticipated thoughts. If you could not take the pain, then you would not want to subject someone else through the same path. Just because the first encounter with this person gave you a poor impression does not mean that they are constantly saying or acting in that manner.

Why English Colonization Never Succeeded Roanoke Research Paper

Why English Colonization Never Succeeded Roanoke - Research Paper Example Spain was on the lead during that time especially in colonizing the West in lieu of propagating the Catholic faith and cramming for the western abundance making them even more powerful in their pursuit of colonizing as many lands as they can. On the other hand, Anglican England would never settle the dispute against Spain but rather made a way in pursuit of finding a new Eden in the western land in finding abundance the same way Spain was having. Hence, on March 25 of 1584, Walter Ralegh secured from Queen Elizabeth a patent which granted him the exclusive right to establish a colony in remote and heathen barbarous lands, countries and territories that were not actually possessed by any Christian prince or inhabited by Christian people.1 In pursuit of a great land that would suffice the criteria that the English monarchy had been looking for, England had set forth a mission to scout for a land that fitted the criteria. As a first step toward pursuing this grand ambition in finding a new settlement in the west, Ralegh commissioned Arthur Barlowe and Philip Amadas to scout a location for the settlement and have found Roanoke Island to be promising with its great and untouched abundance. Roanoke was thought to be perfect and was chosen because it offered protection from Spanish assaults and at the same time it could cradle as a base for launching raids that they had been pursuing for some time to raid Spanish ships and rob them of the good materials they carried. Many great things were written about Roanoke especially by the early colonial settlers that had reached the island. They thought that they successfully penetrated the island but the first land was far from what they expected. The colonizing pursuit never came into realization though no obvious resentment was made by the natives at first because the English colonizers took the process abruptly and dominatingly hurried up to surpass the Spaniards as things were not made with plan but with urge that ignited two different worlds living in misunderstanding and with barriers. Ralph Lane describes Roanoke as having the goodliest soil under the scope of heaven, which is abundant with sweet trees that bring sundry rich and most pleasant fruits compared to Europe’s France, Italy and Spain. Moreover, Lane described it had many sorts of apothecary drugs and food resources such as wheat. Early colonists such as Lane were easily so blinded by the land greatness that they described it as a land of unknown greatness due to the many discoveries that they made during their first step into the savage land. Due to its geographical location and difference from Europe, the climate was very different and was found to be amazing. They found a land of great abundance but claimed that that abundance was hidden from its use since savages resided at the place that they described as being courteous and eager to have clothes rather than silk.2 The early and original settlers of Roanoke before the coloniza tion attempts were Native American Indians. And the whole island was not just actually under one rule with different groups, but with a set of different leaders that did not follow one particular rule. Though the first step of the European colonizers came out well with the first natives that they saw upon touching the grounds of the newly found land, this accommodation did not imply the totality of the native Indians dwelling in the island. The native settlers were likewise awestruck by the coming of foreign strangers and were also amazed by the abundance the outsiders brought in the island, which they had never seen before. Trade instantly came into place as

Feminism in Fifth Business

Feminism in Fifth Business The role of women in the novel Fifth Business is essential and fundamental to the character development and spiritual meaning that Dunny seeks throughout the novel and whether they shape and influence his life in a positive or negative way. Dunny remains in the background essential to the action but not a principal, interlaced in a thread of numerous subplots and themes. Dunny peruses his passion for hagiology which sets him on a journey of discovery through a path of materialism and spirituality plagued by his consistent guilt which carries an underlined theme throughout the novel. The importance of women is consistent throughout the novel since his upbringing in the town Depthford onwards and we will see these women sculpting, damaging or setting him free. The roles of the women will be analyzed through the view of Dunny and how they contributed to his development. The novel Fifth Business which is written by Robert Davies and although they are entirely unalike in character similar experiences enclosed in a fictional reworking of arrangements and situations are consistent with the life of Robert Davies specifically with a similar childhood in a small town in Ontario which give you an account of his thoughts, emotions and experiences in a deeper sense. First, Dunnys mother is a determined and controlling person with a strong and strict Calvinist belief who raises Dunny accordingly which fits her role as a protecting and loving mother who likes to help others, until their situation drastically changes when the focus of her love changes and isolation coupled with resentment builds after the snowball incident with the Dempsters family. This is evident, when Dunny states I began to believe that I was more responsible for the birth of Paul Dempster than were his parents, []. Part of that dreadful fate would undoubtedly be rejection by my mother (Davies 17). Undeniably, his mothers love and focus begins to change attention towards the Dempsters family instead of her own household which initiates Dunnys feeling of isolation and begins to feel resentment for his mother who is unable to provide consolation for his adolescent heart. Furthermore, Dunnys mother continues the passage of isolation and it is particularly felt when Dunny responds Being unofficial watchdog to the Dempsters family was often a nuisance to me and did nothing for my popularity (Davies 22). Obviously, the feeling of isolation is felt by Dunny and it affects his social life with his friends and himself as a person in the future. Next, Dunnys mother imposes fear on his juvenile youth and the resentment for his mother arguably evolves to hate when he is severely beaten by his mother and replies I have been very miserable since-miserable not for an hour but for months on end-but I can still feel that hours misery in its perfect desolation, if I am fool enough to call it up in my mind (Davies 29). Consequently, this incident causes an atmosphere of tension throughout the rest of the novel whenever Dunnys mother is mentioned and he instead turns his attention and love towards Mrs. Dempster. In the long run, Dunnys mother is responsible for his deep isolation, his stance on women, and the insecurities around them which boundaries his feelings and emotion s throughout his life and does anything only through obligation and nothing out of desire for himself which is the reason for his life being miserable and despiteful leaving him unable to form lasting relationships with women and relatively unattached to his mother and women in general. Second, Mary Demspter is considered Dunnys first love and a simple women and more so after the incident with the snowball which is the reason Dunny carries the plague of guilt with him throughout the novel but in essence the guilt remains with himself alone which is a weak cause to hold it against Mary and claim it as her role for she is not the reason it occurred. On the contrary, with that established let us not overlook that Mary plays arguable one of the most vital roles in the novel as Dunnys inspiration for the path of mythology, saints and longing for knowledge and inner spirituality. This begins, with the second miracle when Mary has supposedly raised Willie from his deathbed and Dunnys response to himself is For me, Willies recall from death is, and will always be, Mrs. Dempsters second miracle (Davies 57). Undeniably, to Dunny this is seen as a complete miracle whether anyone believes him or not and will commence his journey of mythology and validating Mary as a saint. Furt hermore, is apparent with the first miracle that occurs but is not known until later when Dunny reencounters Joel Surgeoner and discuses the miracle with him and Joel acknowledges, He worked through that women, and she is a blessed saint, for what she did for me-I mean it as I say it-was a miracle (Davies 135). Clearly, this acceptance of Mary as a saint without a doubt in the eyes of Joel who is forever changed since that night leaves a strong impression on Dunny and motivates him in continuing his direction in the path of mythology and to comprehend the complications and serious possibilities of Mary being a saint. In addition, the third and last miracle is during the war when Dunny is about to lose consciousness and during this time has visions of Mary and her being the Madonna statue but does not fully acknowledge it till later in the novel when he contemplates to himself that, [H]er miraculous appearance to me when I was at the uttermost end of my endurance at Passchendaele (Da vies 161). Without doubt, Dunny is talking within the context of the 3 miracles and confirms to himself that the vision of Mary was the third and final miracle and might be all the proof that he needs to convince himself that it is so but his conviction also plays a destructive influence yet on the other hand brings him academic and personal growth and pleasure. On the whole, Mary plays a critical role providing the three miracles that occur and essentially changes his life profoundly while recognizing her as wholly religious and his experience with her offers him a greater insight about the nature of a life lived with the knowledge of the presence of the mythic world in the actual world and reassures his childhood interest in mythology and saints to come to the forefront of his life and career. Third, Diana Marfleet plays a significant role in the novel as his first meaningful and realistic love but more importantly gently guides him in his self-transformation with the change of his name and being with her made him realize what he really wanted in life and she helped him mentally with the damage that his mother has caused. Plainly, it is clear when his self-transformation begins as Diana is taking care of him and he receives the news of death of his family during the war due to the influenza epidemic of early 1918 and Dunnys remark to himself was, It was years before I thought of the death of my parents as anything other than a relief; in my thirties I was able to see them as real people (Davies 78). It seems that Dunny is finally able to escape his mother even though it was through death it was something he has been longing for and finds great freedom in it while finding closure at the same time during the care of Diana. Also, Dunnys time with Diana helps his figure out wh at he wants to do with his life now that he is physically and mentally able with the care of Diana by his side and the freedom he has just received. Distinctly, being with Diana has made him think about himself for once in life and made him realize that he loves Diana but is not in love with her and that is when Dunny mentions to himself That decision, made at that time, has shaped my life and doubtless in some ways it has warped it, but I still think I knew what was best for me. In the long periods of rest in the hospital I thought as carefully as I could about my situation (Davies 85). Certainly, he is referring to the decision he has made with Diana and how things would not work out between them in the future because she is too similar to his mother which he just got rid of and does not want another. Moreover, to complete his transformation she decides that he should change his name to Dunny which mentally gives him the psychological push to complete and realize his transformatio n into a new person when his reply was I liked the idea of a new name; it suggested new freedom and new personality (Davies 90). Unmistakably, Dunny has taken a liking to his new name which was changed from Dunstable to Dunny and enjoys the freedom and the possibilities that it holds and he remains grateful for what she has made him realize and done for him which no other women has so far. To sum up, it is ironic that consequently Diana who was the one to sever the link between Dunny and his mother by renaming him does not end up marring him and more so because his mothers full name was Fiona Dunstable Ramsay. Nevertheless, his relationship and time with Diana has matured him and broaden his scope of life, understanding and culminated in his rebirth and renaming. In conclusion, the role of women have been extensive and necessary throughout the novel and has matured and turned Dunny into the man he is today although his mother has been the root of the problems in his life the majority of the women have been a positive influence on Dunny and will forever change his outlook on women and life. Dunny has remained and fulfilled his role as Fifth Business by bringing resolution or meaning to the story or merely by observing or explaining it. Throughout the novel he was always the odd man out and continually searching for meaning and significance in life whether it be from his mother who molded him during his childhood, Mary who gave him a lasting connection with the mythology, magic, and the inner spirituality of one self and life or Diana who gracefully opens and heals his heart and mind regarding women and himself again. Ultimately it is an incredible quest for knowledge and happiness which he has finally found even though it was a long and tiring journey with many sacrifices.
