Alternative fuels essays

Alternative fuels essays When attending school to be certified to fix state emission failures, instructors tell stories about emission subjects. One in particular that comes to mind is about a couple that tried to end their lives. The instructor showed a paper clipping, from what paper I do not remember, of an older couple who closed the garage door with the car inside. It was a newer Lincoln. They started the car and waited for the inevitable to happen. The problem was that after five hours someone else noticed the car was running and found the couple. The car was so clean running it could not do what the couple wanted it to do, end there lives. The car was designed to run on gasoline with zero emissions. It almost leaves the air cleaner, than before it uses it. The way individuals move from one point to another has changed over the years. In the last one hundred years, it has been courtesy of the internal combustion engine. Gasoline has been what drives the engine to move the population. The way an engine works is by vacuum being transformed into compression and downward pressure on the pistons by means of combustion of a fuel. The engine's absolute vacuum is created by the pistons being forced downward by an adjacent cylinder connected by the crankshaft. When the valves open it allows air to enter the air intake and the correct stoichiometric mixture of fourteen point seven to one is attempted. If the correct mixture is not achieved raw fuel is released into the atmosphere through the tailpipe as pollution. The amount of fuels that can be run in this style of engine is numerous. Gasoline was discovered years ago by refining crude oil and adding various additives to boost the octane levels. Lead was introduced as an upper cylinder lubricant. It was found not to be necessary, and to be harmful to the environment and health. Most recently, we are trying to reduce emissions from tailpipes of vehicles that run on fossil fuels. These five major emission...

Villa San Girolamo Essays

Villa San Girolamo Essays Villa San Girolamo Paper Villa San Girolamo Paper The Role of the Villa San Giordano Symbolism adds layers of meaning to novels. It can either have a significant, insignificant or negative Impact on the progression of the novel. In Michael Nonnatives The English Patient, the lives of four Individuals are scarred due to the destructiveness of the war. Four Individuals gather at one common area in Tuscany, Italy known as Villa San Giordano (hereafter cited as the Villa). Annotated represents the Villa in many ways. As a representation of a Sanctuary, the Villa protects the lives f the characters, act as a holy place and as a place of refuge. As well, the Villa represents a place where the theme of death and rebirth is present and helps them move past their war wounds. Lastly, the Villa provides a sense of belonging among the characters since they have all been affected by the war In a similar fashion. In the English Patient, Annotated uses the Villa to symbolize a healing aid to the following characters: Kip, Hanna, Aggravating and the English Patient (hereafter cited as Almasys) as it proves to be of greater use than Just a place of rest. The Villa is a representation off Sanctuary that portrays itself as a safe haven, a holy place and a place for refuge. Kip, Hanna, Alms and Aggravating meet in the Walla. Hanna and Almasys room In what used to be a small nunnery before being invaded by German soldiers. As Hanna and Almasys begin their lives together In the Villa, the war Maniacs 2 has yet to conclude. Although not being its primary function, the Villa is providing protection for Hanna and Almasys from the outside world of war and violence. Annotated provides the readers a sense of the conditions in which they were living, From outside, the place seemed devastated. An outdoor staircase disappeared In midair, Its rallying hanging off. [Hanna and Almasys] life was a foraging and tentative safety [Hanna and Almasys] were protected by the simple fact that the villa seemed a ruin. But [Hanna] felt safe here (Annotated,The English Patient, 14). Deeper into the novel the description continues: The Villa San Giordano Had the look of a besieged fortress, the limbs of most of the statues blown off during the first days of shelling. There seemed little demarcation between house and landscape, between damaged building and the burned and the shelled remnants of the earth In spite of the burned earth, In pity of the lack of water. Someday there would be a bower of limes, rooms of green light. (Annotated 43) With Nonnatives descriptions, the environment in which they are living appears harsh, unstable and uninhabitable. This provides protection as it would be unworthy for invasion. This allows Hanna to fully concentrate on Alms healing of the burns on his body rather than protecting themselves from war enemies. This also helps KIP to focus on disarming the bombs around the Villa. Secondly, ten Via Is valley as a only place Decease It NAS a strong resume the garden of Eden. In the biblical garden, Adam and Eve were given Maniacs 3 lance to much more than they needed. They had plentiful food and all the necessities for survival. In the villa, the inhabitants Had enough vegetation planted in the bombed out orchard above the house for them to survive Some beans, some meats (Annotated 7). Hanna spends most of her day in the garden gathering anything she c an from the plants and tries to maintain whatever life the plants have. When the Germans retreated, the Villa was used as a war hospital treating patients of their injuries and later became vacant. The Villa has plenty of first aid material making it easy for Hanna to tend to Alms injuries. Throughout the course of the novel, the characters in the Villa are not faced with destruction despite the many hidden, UN- detonated bombs. This can be Gods watchful eye over the recovering characters. With the given necessities, the characters in Villa have all the essentials needed to aid in their healing. Lastly, the Villa is also seen as a place of refuge where the characters are safe and in a place of shelter from danger. The obvious danger in the novel is the passing war but a second danger in this novel is the former life of these characters. Hanna is desperately trying to remove the memory of the loss of her husband and unborn hill. Kip is trying to remove himself from his Indian heritage and become Westernizes. Aggravating is trying to remove the memory of captivity by the Germans as he was attempting to steal information. As well, Alms is trying to carry on his life with severe burns to his body. None of these fragile characters is whole in either body or soul; each is a casualty of this desperate age (Williams, Canadian Literature. N. Page), Williams describes how the lives of these characters are at a breaking point. The fragility of these characters explains why they need a new beginning; a way to start anew. The Maniacs 4 sat life of these characters has been devastating an d very tragic making them difficult to heal. They come together at the Villa, depicted as a vacation place from their past lives. The Villa helps begin a new chapter in their lives. As a safe haven, the Villa provides protection and shelter from the passing war. As a representation of the garden of Eden, the Villa is viewed as a holy place. Lastly as a place of refuge, the characters are able to come together and help rid themselves of terrible memories. The Villa, presents these three qualities of a sanctuary that allows the characters to progressively heal over the course of the novel. The theme of death and rebirth is apparent in The English Patient. Rebirth is a term commonly used to describe a new beginning and is present in various ways in the novel. The characters in the novel experience a death and rebirth scenario that forces them to take on a new life. Prior to his accident, Alms was a highly trained general in the army. As he is in flight with an old war plane, the plane is leaking oil and later ignites. The flames engulf Alms and he Jumpers out of the plane to try and save himself: [Alms] dug down towards the tarpaulin, and Madams old plane gradually emerged The plane came out of the sand He looks down and sees oil pouring onto Nils Knees en plots up an a ten 011 sees all over ten seat .. I nerve was a spark from a short, and the twigs at her knee catches fire Pivots upside down breaking free of glass, wind flinging his body back And he is in air, bright not knowing why he is bright until he realizes hes on fire. (Annotated 174-175) Maniacs 5 Although not physically experiencing death, this crash and burn is a figurative death of an old life, the life off soldier of war. Having sever burns, he is saved by a tribe named the Bedouin and is taken under the care of Hanna who believes he is too fragile to move. Instead of leaving the Villa with the army, she decides not to move Alms, She would remain with the one burned man the call The English patient, who, it is now clear to her, should never be moved because of the fragility of his limbs (Annotated 51). Alms begins his new life in the Villa under Hennas care. Alms plane crash figuratively signifies his death and his rebirth brings him to the Villa. With the injuries sustained, he is no longer able to fight in the war. The rest allows his body to heal from his severe physical injuries. Learning of her fathers passing from the war, Hanna experiences pain not many an relate to, The way Hanna broke in Santa Chair Hospital when an official walked down the space between a hundred beds and gave her a letter that told her of the death of her father (Annotated 41). When the opportunity arises to care for this fragile patient, she Jumps at the chance. She views Alms as a way to fill a void in her life by personally assigning the role to herself. With the role off full time nurse, she recognizes that she must to do everything in her power to care for the dying patient. She has nursed him for months and she knows the body well (Annotated 1). At this point, Hanna experiences a death and rebirth. Hennas father passes away and she is given no choice but to abort her baby. As she takes on the role of being the nurse of Alms, this is the start of her new life that begins at the Villa. Helping Alms with his Maniacs 6 injuries allows her to forget the loss of her father and child by taking her mind off of them, allowing her to heal mentally. Aggravating, a friend of Hennas father, is on a mission to steal some information from the German army that later captures him. Before escaping, they sever his thumbs as a way of punishment. After being in the hospital in bandages for four months, he goes in search of Hanna when he learns from the doctors that she is living in the Villa. Hanna is delighted to see Aggravating once again but fears there will not be enough food available for the three of them: We need some chickens. [Hanna] is looking at Aggravating, knowing his skills from the past, not quite saying it. l lost my nerve, [Aggravating] says. Ill come with you, then, Hanna offers. Well do it together. You can teach me how to steal, show me what to do. You dont understand. I lost my nerve. l was caught. They nearly chopped off my bucking hands. (Annotated 33-34) Without the use of his thumbs, Aggravating believes he is useless and inadequate. Tater Telling Hanna, en access to remain In ten Via. In tens case, ten Tie AT a war soldier dies after the severing of his thumbs, since he would be of no use to the army. The life without the use of his th umbs begins at the Villa. Beginning his new life here helps him forget his injury and progressively heal mentally by not feeling useless anymore. Finally, Kip, a British sapper who does not fear death at all, makes his way to Maniacs 7 the Villa. A sapper is a name given to those skilled in diffusing bombs. One night, during a party in Alms room, there is an explosion outside. Kip does not think much of it until he examines the damage. He finds his friend Hardy, another sapper dead, He had found the location of the death and what was left there and they had buried his second in-command, Hardy (Annotated. 113). At this point, Kip comes to the realization of how dangerous his Job really is. This realization brings forward a new side of Kip, from being fearless of death to being fearful. This realization heals him mentally by making him see the danger in his Job placement which helps inhibit IM from taking risks. The characters in the novel all experience diverse deaths and rebirth as they congregate at the Villa to help represent the healing that occurs at the Villa. Furthermore, the Villa itself experiences a death and rebirth scenario. Ata point in time during the war, the Villa was the home of German soldiers. As the Germans were forced to retreat, the Villa became a war hospital and later became vacant. After the destruction of the war subsides, nature fills this area with new life. The characters presently living in the Villa are forced to learn how to live again after the extraction of the war. In Learn Gileitiss paper she writes the inhabitants of the villa are all displaced because they are exiles who have found new identities in a place other than their homeland (Glittle Identity Crisis in Michael Nonnatives The English Patient. N. Page). In other words, the characters in the Villa begin a new life and find new identities for themselves allowing them to live a new life. A town that is scarred by war debris is now a new home. Its a formation off new community. With the four characters involved, they too must learn how to adapt to the changes to their odd. The Maniacs 8 Villa, therefore, proves to be the starting point of new life by allowing the theme of death and rebirth to appear in The English Patient and for the characters to heal individually. Whether it is physical or mental damage, the characters are living through some kind of pain. The fact that the characters are living together under one roof provides a sense of belonging amongst them as a community. With the traumatic injuries they experience, an individual may feel despair, but they are able to feel a part of a group. They each find their new life despite the wounds they carry. All four characters are able to relate to one another since they have all suffered from the war: For the four inhabitants of the Villa San Giordano the only way out of their own suffering is through each other (Historian In Near Ruins n. Page). Isolated from the war ravished world, the characters in the Villa can connect and support each other to be able to live their transforming lives. The Villa allows the inhabitants to recognize that they are not alone in their suffering and many others share their wounds. It is through these wounds that new friendships and relationships are created, The residents of en Via as Allspice Monolinguals Tar away Trot tenet melanoma nave unreal physical and psychological wounds They try to heal themselves through their friendship while their old identities have dissolved (Guillotine n. Page). Hanna loves Alms and Alms grows fond of Kip and Aggravating since all three played a part in the war. Also, a sexual partnership between Hanna and Kip is formed. These relationships creates a more comfortable setting in the Villa aiding in recovery time for the characters. Maniacs 9 Annotated is able to portray the Villa as a community of diverse individuals that encourages their sense of nationality. After the news of the bombing of Hiroshima and Nagasaki, Kip realizes who he truly is, an Indian. Kip, who does not believe in Western aggression, discovers that it is still present through the bombings, Never trust the Europeans, [Kips brother] said When you start bombing the brown races of the world, youre an Englishman They would never have dropped such a bomb on a white nation A new war. The death of a civilization (Annotated 284-286). Kips brother is very anti-European, he is a man who always stuck to his roots, unlike Kip. This shows that no matter how hard you try to remove yourself from your roots, they will always be apparent. Furthermore, Annotated reveals Alms identity as Hungarian spy and desert explorer who helps the Germans navigate through the deserts. By trying to not remember who he is, his identity was not known until the latter stages of the novel. The last person I expected to find here in the shelled nunnery was [Alms] (Annotated 252) said by Aggravating. Annotated also uses the villa to reveal more information about the characters living in it. Hanna is constantly trying to erase the memory of war and hide from her adulthood. To erase the memory of the war, Hanna lives in the Villa and takes Alms under her care, viewing him as a defenseless child. She re-lives her childhood by p laying hopscotch on her free time in the dark hall: She drops the chalk into the pocket of her dress. She stands and pulls up the looseness of her skirt and ties it around her waist. She pulls from another pocket a piece of metal and flings it out in front of her so it falls Just beyond the farthest square. (Annotated 15) Maniacs 10 Hanna is constantly re-living her childhood by doing activities typically done by children because of the shell shock she experienced during the war. Lastly, Aggravating is trying to forget the memories of the torture he endures as a captive. The community-like atmosphere around the Villa provides a sense of belonging amongst them. Along with this, the Villa allows the characters to become more comfortable with their fellow Villa- mates. It also provides a representation of a house of nations. The Villa is able to connect four individuals that share a common thread by their involvement in the war. These characters come together despite having different nationalities but the Villa is able to prove that no matter the race or nationality, people get along, as a family unit. The villa is a place, once again, A symbol of their friendship as they seem to disregard their national and racial origins Here nations, races anything artificial that divides human beings is meaningless (Guillotine n. Page). An example is the celebration of Hennas 21st birthday In Alms room. Nonnatives Is addle to relate ten lives AT Tour snatchers tongue a small Villa that aided in their healing process. Victoria Acidosis explains in her critical summary that, In the Villa San Giordano in Italy, four shattered survivors cope with the physica l and emotional suffering the war has brought about. They come from different parts of Europe UT they share similar kinds of pain (Acidosis The English Patient n. Page). The Villa proves to be a major symbol in The English Patient. The story line of the novel is set in the Villa. In many ways, Annotated is able to use the Villa as a way of healing the injured. The Villa is able to heal the characters as a representation of a sanctuary by providing all the necessary items such as first aid materials as well as protecting them from any danger. The Villa Maniacs 11 also allows the theme of death and rebirth to occur by being the starting point of heir new life.

Criminology - Essay Example All of these ideologies have their impacts on all spheres of the society including thegovernment. Socialist ideologies stand for maximization of wealth and opportunities for all people through communal control and ownership of social services and industries. Socialism aims to reduce human suffering and promote equality and enhance quality of life for all people. Unlike capitalism which aims at private ownership and control of property; socialism believes that communal ownership and control of property is what the world needs for the benefit of everyone. Socialism came into being in the 19th century when the industrial revolution started (Caputo, 2011). Over the years, socialism has had he impacts on government policies. While many have viewed socialists as anti-government forces, others believe that it is because of socialists that many people today are able to access basic social services. Socialists have fought for human rights and helped in the promotion of equality and inclusivity within the government. Social policies influence different areas of life such as education, health and social care. As a result, they also influence how the government formulates its policies (fried, et. al, 1992). In the 1980s, the Conservative Social Policies were very common in the UK. The Conservative Party introduced the New Right thinking in the UK under John Major. The party also showed special preference to the nuclear family. The party influenced the formation and enactment of the Child Support Agency and the Family Law Act in 1996. The Child Support Agency aimed at making sure that fathers provided child support even when they were no longer with the mother of their child (Bochel, 2008). Socialists believed that this would reduce suffrage for single mothers and that children would not lack anything despite not having a father around them. This benefitted the government as it reduced theamount of money the state paid to single mothers. The Family Law Act was

They are also more qualified than their baccalaureate prepared counterparts to collect, analyze and interpret statistical data in order come up to identify problems within the health sector and design solutions to these issues. This paper discusses the competencies the masters’ prepared nurses acquire during the program and how they aid in improving the health sector. Nursing as an education and a profession is able to address some of the critical issues that arise in this evolving health care system. A study conducted in the USA showed that the US government could save up to 8.75 US dollars annually if hospitals used advanced practice nurses (APNs) in place of physicians for some medical cases. This way they can also plan for their career (American Association of Colleges of Nursing, 2007). They also help the consumers because they ensure that the service the patients they receive is of high quality and meets set standards. This paper will examine masters’ level competencies for determining the areas that need improvement and if they are still viable given the health care system. I will hence discuss competencies from the American Association of Colleges of Nursing (AACN), Quality, and Safety Education for Nursing (QSEN) and National League for Nursing (NLN). The AACN outlines master-level competencies for adult nurse practitioners that add to the core competencies for all nurse practitioners (American Association of Colleges of Nursing, 2007). The adult nurse is the provider of direct health care services. Within this role, the nurse applies nursing theories, scientific knowledge, and contemporary clinical knowledge to assess and manage the health and illness state of a patient. In the assessment of health, the adult nurse practitioner assesses all aspects

Ethical Issues in the Criminal Justice Field (Untruthfullness) Article

Ethical Issues in the Criminal Justice Field (Untruthfullness) - Article Example s; stealing money and/or drugs from drug dealers; selling stolen drugs; protecting drug operations; providing false testimony; and submitting false crime reports† (General Accounting Office, 1998: 8). Between 1993 and 1997, at least half of the law-enforcement personnel convicted of corruption offenses while on duty were led to their actions through drug-related activities. In addition, more than 100 drug-related cases involving police officers are prosecuted within the country every year. Another indication of the widespread problem is found in the fact that all of the nation’s federal drug enforcement agencies have had at least one of its agents implicated in a drug-related offense. Throughout the country, officers have capitulated to the same temptations and potential rewards of the drug market that attracts their criminal counterparts. The ethical cost of this corruption has far-reaching repercussions not only within our law enforcement units, but also in our concept ion of society itself. It seems the causes of police corruption would be fairly easy to explain given the tremendous rewards associated with the drug trade. The financial rewards offered by the sales of illegal drugs in relation to other forms of income are enormous. This temptation comes on top of an increasing sense of frustration among law enforcement officers realizing the futility of their efforts as the number of drug traffickers continues to grow. This is also exacerbated by a society that has come to value material wealth much more than personal integrity or honorable behavior. The War on Drugs has been officially declared for 30 years now, resulting in the incarceration and prosecution of millions of people, but there has been no discernable positive effect. Drugs are now more available, cheaper and often more potent than ever before. Disheartened police officers often put their lives in jeopardy daily to fight against drugs, but must also deal with being under-paid and

Impact of Volcanic Eruptions on Iceland

Impact of Volcanic Eruptions on Iceland Massimo Fanara Describe the three different types of volcanic eruptions that have given rise to rise to Iceland’s volcanic landforms. There are three different types of volcanic eruptions based on the lava texture. These are; Effusive: eruptions in which lava with low viscosity and settles on the side of the volcano forming gentle slopes. In this type of eruption, gases escape easily and thus there is no explosions due to the build-up of pressure (The Geological Society, 2014). Explosive: occur when gas pressure builds up in the volcano until it is released catastrophically. The highlyviscousmagma magma is trapped in the volcano by a blockage, which prevents gases from escaping. As the magma rises towards the surface, pressure increases until a weak point in the blocked crater is found. At this point all the pressure is released in a massive explosion of pyroclastics, volcanic gases and lava (The Geological Society,2014). Mixed: Eruptions involving explosions and magma flows Describe the characteristics of a thuya. How does this acquire its distinctive shape? Tuyas are eruptions occurring underneath ice sheets resulting in a layer-cake structure with a flat-top and steep-sidedvolcano. This steep sided layer-cake shape results from the rapid cooling of lava which does not travel far from the vent and thus piles up into a steep-sided mount. When the eruption is long enough that melts all the ice, a flat cap of basaltic rock on top of the hill is formed. Definethe term jà ¶kulhlaup and explain its significance to Iceland. Jà ¶kulhlaups: refers to an outburst flood event of glacial origin. Jà ¶kulhlaups erode, deposit, and re-work sediment simultaneously; they usually cause significant glaciological and sedimentological impacts creating large canyons and transport sediment and icebergs over vast outwash plains and sandur deltas (Russell, Roberts, et al., 2005). Another important aspect of jokulhlaups is the significant heat exchange between the magma and glacier, which result in subglacial eruprions and formation of hyaloclastite ridges and tuyas (Bjà ¶rnsson, 2010). What are the origins of Icelandic river waters? Describe the relevant main characteristics. Most of the Icelandic river waters originate from abundant glacier melting. This result in distinctive characteristics including; Huge amount of debris High turbidity Usually yellowish-brown in colour. The maximum discharge usually occurs in July or early August. Most of the rivers are unnavigable. Explain  the following terms: (i) tephrachronology, (ii) crytotephra,and (iii) isopachs. Tephrochronology: is a method for relating and dating geological, palaeoecological, palaeoclimatic, or archaeological sequences or events (Lowe, 2011). Crytotephra: It involves the use of volcanic ash which travelled long distances and which may have formed distinct but invisible layers within a sites stratigraphy (Lane, Cullen, et al., 2014). Isopachs: Isopachs are line drawn on a map connecting all points of equal thickness of a particular geologic formation. These allow the user to create isopach mapsillustrating variations in thickness within a layer orstratum. Isopach maps are used are utilized inhydrographic survey,stratigraphy,sedimentology,structuralgeology,petroleum geologyandvolcanology. One measure used totackle the problem ofsoil erosion is re-seeding with appropriate floral species. What characteristics of a plant would make it suitable for such a purpose? Roots are important structures not only for the plant but also for the underlying terrain. Plant roots; Describe one method that could be used to measure the profile of a beach. Beach profiling can be carried out by the use of a clinometer. This method consist of first, finding two points to use as reference points which define the line to follow when measuring a beach profile. The instruments needed are a clinometer, a compass, GPS (for the starting point coordinates), a measuring tape and a piece of wood (to place the clinometer on it when taking the readings). Measurements of the beach surface are taken by the use of a clinometer which measures the angle of the slope. This is done at different intervals between the two reference points until the sea is reached. Explain the following: (i) lateral moraine, (ii) kettle lake, and (iii) outwash plain. Lateral moraine: Unconsolidated material deposited on the sides of an alpine glacier. Most of the material deposited results from the freeze-thaw weathering of alpine valley walls (Lemke, 2010). Kettle lake: Kettles arefluvioglacial landforms created when depressions left behind by the melting of partially-buried ice blocks are filled with water (Schaetzl, n.d.). Outwash plain: Outwash plains areplainsformed fromglacialsediments such as gravel, sand and claydeposited by meltwater outwash at the terminus of aglacier (The Geography Site, 2006). Explain the presence of wave-cut platforms in areas ofIceland presently distant from the coast. Studies were carried out on the lithostratigraphy and biostratigraphy in the northern coast of Iceland in the attempt of reconstructing deglaciations relative sea level changes. According to these studies sea level felt by approximately 45m between 11300 and 9100 BP. This corresponds to an isostatic rebound of 77m. Therefore, this change in sea level explains the presence of wave-cut platforms distant from the coast (Rundgren, Ingolfsson, 1997) Distinguish between mafic and felsic lava. Mafic lava: is less viscous than felsic lava due to lower silica content. This causes non-violent eruptions where lava moves slower. Mafic lava tends to be associated more with interplate volcanism and mid-ocean ridges and produces basaltic type rock. Felsic lava: found mainly at convergent zones. This type of lava has a high silica and water content, causing the lava to be highly viscous and causes very violent eruptions. This lava produces rhyolite and andesitic rocks. What is the nominal fix accuracy of a GPS? Why can a DGPS improve this nominal accuracy? Nominal fix accuracy of a GPS is how accurate a GPS can be. There are several factors affecting the accuracy such as atmospheric effects, sky blockage, and receiver quality. A higher accuracy is attained when using GPS in combination with augmentation system. These enable real-time positioning to within a few centimeters (National Coordination Office for Space-Based Positioning, Navigation, and Timing, 2014). A Differential Global Positioning System(DGPS) is an enhancement toGlobal Positioning Systemthat provides improved location accuracy, from the 15-meter nominal GPS accuracy to about 10 cm in case of the best implementations. The DGPS is a combination of local land stations connected with satellites for more accurate data. In cartographic terms, explain why the datum used by a GPS navigation set must be the same as for the reference chart being used. A datum is any numerical or geometrical quantity serving as a reference point from which to measure other quantities. With regard to chart datums, these are also used in plotting GPS positions or transferring positions from one chart to another. When plotting and transferring points from one chart to another GPS positions must be on the same datum as the chart being used in order to prevent any inconvenience regarding with hazards and safe distances.

The Battle for Space in Shaw Essay -- Development Space

The Battle for Space in Shaw "Groups, classes or fractions of classes cannot constitute themselves or recognize one another as ‘subjects’ unless they generate (or produce) a space. Ideas, representation, or values which do not succeed in making their mark on space†¦.will lose all pith and become mere sign†¦Space’s investment - the production of space – has nothing incidental about it: it is a matter of life and death." Henri Lefebve, The Production of Space Lefebvre's quote speaks of the production of space as a common, inevitable Occurrence. Different groups, organizations and people, are constantly producing spaces. These groups are in existence only because they have generated a space and occupied it. Today, a battle for space is occurring throughout DC and other urban areas throughout the country in the vision of new Global, high tech cities. What is left of the existing space and the people who occupied it prior? Lefebvre suggests that these 'ideas, representation, and values' that are unsuccessful in keeping their ground eventually fade and become mere memory.
