The geographical history of Map making Research Paper

The geographical history of Map making - Research Paper Example This paper seeks to explore the science of map making with respect to its rich history culminating to modern maps. A map is a diagrammatic representation of a part of the world using from a bird’s point of view to provide guidance to the user on designated landmarks and geographical locations. In this respect, maps indicate the location of important elements in a specified part of the world such as political boundaries, natural resources, roads, topography, as well as economic activities. The science, study, and the art of making maps are descriptive of cartography, which involves examining the information conveyed, and its effective application. The importance of maps cannot be understated as they serve to provide guidance and direction to an area of interest. In this regard, exploration of new areas is easily facilitated by studying maps relevant for direction to various regions. This ensures safety of individuals involved, as they are aware of their surrounding keeping away from potential harm such as cliffs, raging waters, and hot deserts, which facilitates effective tourism. Similarly, geographical illustrations indicate flight patterns that ensure safety in air travel. Notable also is the role of maps in illustrating weather patterns, which is critical for individuals in the vicinity. To this effect, warning can be delivered effectively to residents in the event of eminent weather catastrophes. Maps also serve to safeguard infrastructure through effective planning and engineering. For instance, utility companies such as gas and electricity own maps indicating their infrastructure network, which is critical in the management of cities. This ensures that developers are aware of the network and thus work around it to preserve its integrity and avoid economic repercussions. The most remarkable role of maps, to both ancient civilisations and modern society, is demarcation of borders at national and international levels. This is critical to enhance peace and foster cohesion amongst different cultures in the world. Maps provide a unique opportunity to establish territorial boundaries that fundamental in defining jurisdiction with regard to legal systems and economic activities. International boundaries are often vocal in determining trade among nations, which serves to influence prices of various products such as oil in the world. In addition, maps are of economic importance owing to illustrated trade routes and cargo tracking, which provides essential information to various business parties. In essence, maps are important tools that facilitate understanding and navigation of the world around us. Depending on the application, various kinds of maps exist to illustrate different aspects of the world’s phenomenon. Physical maps indicate identifying physical features of the land with respect to terrain, topography (elevation), rivers, lakes, seas, and oceans. These find effective application among explorers in their navigation an d among policy makers as they plan development projects. Similarly, movement maps are highly specialised to indicate transport networks such as road maps in order to guide users on how to get a round. Distribution maps highlight the presence or absence of a desired interest in an area; for instance, the maps can be used to illustrate demographics or the availability of natural resources in a region. Political maps highlight national and int

Skulls identification Essay Example | Topics and Well Written Essays - 500 words

Skulls identification - Essay Example It also has larger teeth than those of modern humans and the jaw also lacks the projecting bony chin that is found in Homo sapiens. They had large supraorbital height since they had large orbits which suggest they had large eyes and visual cortices. Nuchal area height is small and this is as a result of the high condylar position. Condylar position is quite high and the reason as to why there is imbalance of the head. The taxonomic status of the Mystery skull # 2 is Homo erectus. This is so because the skull has a large face with low, sloping forehead and a massive brow ridge. It also has a broad and flat nose. The skull is also broad and long with sharp angles at the rear unlike the curve found in modern humans. The bones of the skull are very thick and formed a small central ridge, also called midline keel, along the top of the skull. The jaws are large and thick without pointed chin. The molar teeth have large roots which are decreasing towards a modern size. Other than the mentioned, the mystery skull #2 has a rounded skull, a steeper face, and smaller teeth that justify that it matches those of Homo erectus. In Homo erectus, the supraorbital height was enlarged though smaller than that of newly found skull which indicted they had small eyes. They have a well-developed opened masticatory apparatus which clearly define the nuchal area height. Though it had well developed nuchal musculature, th e balance of the head was still less perfect that it is today on modern humans. Condylar position is higher compared to that of Australopithecus aficanus because it has well developed nuchal area that can balance the head. The taxonomic status of the Newly Found skull is Australopithecus aficanus. This is so because the jaws and teeth are midway those of humans. The incisor and canine teeth are shorter and smaller. The gap (diastema) amid the canines and next teeth also shows that the Newly Found skull matches Australopithecus

Case study: The Treatment of Depression

Case study: The Treatment of Depression Although depression has been recognized as a clinical syndrome for over 2000 years, as yet, no completely satisfactory explanation of its puzzling and paradoxical features has been found. There are still major unresolved issues regarding its nature, its classification and its etiology. (Beck and Alford, 2009, p3) However, the importance of depression is recognised by everyone in the field of mental health. According to Kline, more human suffering has resulted from depression than from any other single disease affecting mankind. (Kline, 1964) Hammen (Hammen,1997,p3) states that the term depression is used in everyday language to describe a range of experiences from a slightly noticeable and temporary mood decrease to a profoundly impaired and even life-threatening disorder. The severity of depression is generally defined according to the number of symptoms present, the severity of the symptoms and the severity of the associated functional impairment or distress. (Whisman, 2008, p66). This is done by health professionals using the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), a publication where each mood disorder is characterised by a unique set of symptoms or diagnostic criteria which are split into 4 areas: Affective Behavioral Cognitive Somatic The Cost of Depression Government advisor, Lord Layard, worked on a report back in 2004 that outlined mental illness as the biggest social problem facing Britain today. (Layard, 2004) The report pointed to the Psychiatric Morbidity Survey, which suggested that one in six British people would be diagnosed with depression or anxiety at some point in their lives. Yet only one in four of people with emotional disorders receive proper treatment. It imposes heavy costs on the economy (some 2% of GDP) and on the Exchequer (again some 2% of GDP). There are now more mentally ill people drawing incapacity benefits than there are unemployed people on Jobseekers Allowance. Mental illness matters because it causes massive suffering to patients and their families, because it prevents them contributing fully to society, and because it imposes heavy costs on taxpayers. (Layard, 2004). A UK wide strategy to help people with depression was required. The vehicle for this was through the NHS. In September 2007, the UK government launched the biggest state-funded mental health initiative ever. It pledged  £170 million to create a ground-breaking therapy service in Britain, according to health minister Alan Johnson. The service was to include 3,500 extra psychological therapists trained in CBT to be found and trained by 2011. (Evans, 2007). What is CBT? CBT (Cognitive Behavioral Therapy) is the treatment of choice within the NHS for depression. According to The Royal College of Psychiatrists (2010); CBT is a form of psychotherapy which involves: How you think about yourself, the world and other people How what you do affects your thoughts and feelings CBT was developed by Dr Beck, a psychiatrist at the University of Pennsylvania in the early 1960s. Dr Beck had previously studied and practiced psychoanalysis. He designed and carried out a number of experiments to test psychoanalytic concepts on depression. Fully expecting research would validate these fundamental precepts, he was surprised to find the opposite. Beck Institute website (1999-2009) This research led him to begin to look for other ways of conceptualizing depression. Working with depressed patients, he found that they experienced streams of negative thoughts that seemed to pop up spontaneously. He termed these cognitions automatic thoughts, and discovered that their content fell into three categories: negative ideas about themselves, the world and the future. He began helping patients identify and evaluate these thoughts and found that by doing so, patients were able to think more realistically, which led them to feel better emotionally and behave more functionally. (Beck Institute 1999 2009). According to the NHS Choice website (2010) Cognitive Behavioral Therapy differs from most other types of psychotherapies because it is: Pragmatic Highlight structured Focused on current problems Collaborative Cognitive behavioral treatments are developed with particular cognitive contents in mind they are disorder specific. (Scott, 2009, p2) Depression: Cognitive Therapy For people with persistent subthreshold depressive symptoms or mild to moderate depression, consider offering one or more of the following interventions, guided by the persons preference: Individual guided self-help based on the principles of cognitive behavioural therapy (CBT) Computerised cognitive behavioural therapy (CCBT) A structured group physical activity programme Drug treatment Do not use antidepressants routinely to treat persistent subthreshold depressive symptoms or mild depression because the risk-benefit ratio is poor, but consider them for people with: a past history of moderate or severe depression or initial presentation of subthreshold depressive symptoms that have been present for a long period (typically at least 2 years) or subthreshold depressive symptoms or mild depression that persist(s) after other interventions. For Those with Moderate or Severe Depression: For people with moderate or severe depression, medical practitioners are advised to provide a combination of antidepressant medication and a high-intensity psychological intervention (CBT or IPT). (NICE Guidelines 2009) The Royal College of Psychiatrists (2010) highlight the medication used within the NHS for the treatment of depression to include: Tricyclics MAOIs SSRIs SNRIs NASSAs Although medication can help lift the patients mood, it does not tackle any underlying problems they may be experiencing. There are also various known side effects to the medication including abdominal pain, nausea, headache, suicidal thoughts, constipation, blurred vision to name but a few. People react differently to different drugs, so until they try them they are unable to know if they will have a negative impact on them. Psychological therapies can help patients to explore what may have contributed to their depression in the first place, and what might be keeping them depressed. (Depression Alliance UK, 2010) CBT can be done individually or with a group of people. It can also be done from a self-help book or computer programme. Unfortunately, in many parts of the country, there are long waiting lists for CBT and sometimes people end up going to private therapists instead of waiting to see an NHS appointed therapist. The Benefits of CBT in the Treatment of Depression The Royal College of Psychiatrists (2009) state that: CBT is one of the most effective treatments for conditions where anxiety or depression is the main problem. It can help patients break the vicious cycle of altered thinking, feeling and behaviour. It is the most effective psychological treatment for moderate and severe depression. It is as effective as antidepressants for many types of depression. This is also supported by Townend, Grant, Mulhern and Short (2009, p 254) who state that CBT remains the psychological therapy with the widest and broadest evidence base. This is also backed by (Gabbard, Beck and Holmes, 2007, p115), CBT has been demonstrated to be an effective treatment for depression in the large number of studies that have accumulated since the original study by Rush et al (1977). They go on to say that CBT produces a greater improvement in symptoms than no treatment or waiting list controls (Dobson 1989) and demonstrates equivalent efficacy as pharmacotherapy for depression. This is also further supported by (Freeman and Power, 2007, p30) who state, There have been numerous randomised clinic trials that support the efficacy and effectiveness of cognitive therapy for depression, across a variety of clinical settings and populations (for review, see Clark, Beck and Alford 1999; De Rubeis and Crits-Christophe 1998; Dobson 1999; Robinson,Berman and Neimeyer 1990) (Freeman and Power, 2007,p30). According to (Ingram, 2009, p174) In the acute treatment phase, combination therapy, consisting of medication and CBT, has been found to be superior to either medication or CBT used alone for patients with more severe, recurrent or chronic forms of depression. (Gabbard, Beck and Holmes, 2007, p115), state that One of the main potential benefits of CBT for depression is that it reduces relapse / recurrence to a greater extent than antidepressant medication. Today, CBT remains the gold standard for the treatment of depression with psychotherapy (Wasmer-Andrews, 2009, p3). The Limitations of CBT in the Treatment of Depression However, although highly praised, CBT does have its limitations and indeed its critics. In terms of limitations, these are set out below: To benefit from CBT, the patient needs to commit themselves to the process. A therapist can help and advise, but cannot make someones problems go away without the patients co-operation (NHS Choices, 2010). Therefore, the patient needs to be open to CBT and play their part in their recovery, including taking a full part in each therapy and doing their homework in order to recover from depression. This is also highlighted by the Royal College of Psychiatrists (2009) who state that CBT is not a quick fix. A therapist is like a personal trainer that advises and encourages but cannot do it for a patient. If a patient is feeling low, it can be difficult for them to concentrate and get motivated. (Royal College of Psychiatrists,2009) Because of the structured nature of CBT, it may not be suitable for people who have more complex mental health needs or learning difficulties. (NHS Choices, 2010) This is further supported by (Wasmer-Andrews, 2009, p3) who states that CBT has limitations for treating certain groups, including people with treatment-resistant depression and those with both depression and a personality disorder. Critics of CBT argue that because the therapy only addresses current problems and focuses on very specific issues, it does not address the possible underlying causes of mental health conditions, such as an unhappy childhood. (NHS Choices, 2010). This is something that could be achieved using a Diagnostic Scan under hypnosis, if hypno-psychotherapy could be used instead. CBT focuses on the individuals capacity to change themselves (their thoughts, feelings and behaviours), and does not address wider problems in systems or families that often have a significant impact on an individuals health and wellbeing. (NHS Choices, 2010) The Royal College of Psychiatrists (2009) state that For severe depression, CBT should be used with antidepressant medication. When a patient is very low, they may find it hard to change the way they think until the antidepressants have started to make them feel better. Critics of CBT in the Treatment of Depression Critics of CBT, as with all clinical theories, vary depending on the thoughts of the analyst. Townend, Grant, Mulhern and Short (2009, p 254) point to many of these discussions. Specific issues have been raised over the necessity of, for example, challenging thoughts in CBT (Longmore and Worrell, 2007); and cognitive interventions in severe depression (Dimidjian et al, 2006). Additionally, there is still ongoing discussion (e.g. Gilbert and Leahy, 2007) about the nature an impact of the therapeutic alliance as causes of the changes seen in CBT. Weiner, Freedheim and Stricker (2003) point out that Although the scope and efficacy of CBT are impressive, much work needs to be done. In particular, future efforts of CBT clinical researchers must demonstrate the effective of treatments outside research centres as well as turn more attention towards disorders overlooked by CBT (e.g. personality disorder). Kotler and Shepard (2008) highlight that human beings are multi-faceted, with feelings as well as thoughts. It is suggested that CBT puts undue emphasis on thought processes to the exclusion of many legitimate feelings, thereby contributing to repression and the denial of feeling. They go on to highlight some other criticism leveled at CBT as follows: CBT is less effective with some kinds of clients those who have a problem with overintellectualising or those who dont have the capacity to reason logically, or clients with minimal intelligence (e.g. young children, very old people, schizophrenics and those with other personality disorders). Many CBT therapists complain of boredom and burnout from continuously repeating the same arguments and processes with all clients. CBT is difficult for some people for some professionals to practice if they are not outgoing and assertive and dont enjoy vigorous debate and confrontation. Because the therapists role is so verbal, active and direct, the client may feel overpowered, dominated and not responsible for the outcome. (Kotler and Shepard, 2008) The Debate There is much debate on the subject of CBT as a treatment for depression within the NHS. Oliver James article (James, 2006) sumarises much of this debate. He indicates that Depression and anxiety costs the (British) economy  £17 billion per year. Being cheap, quick (15 20 sessions) and simplistic, CBT appeals to the Government. In fact, in June 2006, Professor Richard Layard labeled the government happiness tsar claimed that CBT can lift at least half of those affected out of their depression or their chronic fear. (James, 2006) Another attraction for the government is that CBT aims to get you to a point where you can do all this on your own and tackle problems without the help of a therapist. (NHS Choices, 2010). Thereby, it is argued that using CBT could reduce the future costs of treatment in current users. In addition, there are also now computerised CBT approved for use by the NHS Beating the Blues which has been approved for the treatment of depression. (NHS Choices, 2010). Again, this is a cost effective treatment for some people who find they prefer using a computer rather than talking to a therapist about their private feelings. (NHS Choices, 2010) In a follow up article, in March 2009 (James, 2009) resurrected the debate when he reported that CBT is not a real cure, just a form of personal spin. He went on to argue that work by eminent US psychologist, Professor Drew Weston found that after two years, two thirds of those who had CBT for depression has relapsed or sought further help. It is important for patients to keep practicing their CBT skills, even after they are feeling better. There is some research that suggests CBT may be better than antidepressants at preventing depression coming back. (The Royal College of Psychiatrists, 2009) James (2009) went on to argue that If given no treatment, most people with depression drift in and out of it. After 18 months, those given CBT have no better mental health than ones who have been untreated. On the other hand, in the same article by James (2009), Derek Draper a CBT practitioner and author states that CBT draws on the obvious truth that how we feel is inextricably linked to the way we think and behave. It isnt remotely sinister and is rather simple and it works. Many of my patients have been helped by CBT. New Research According to the Royal College of Psychiatrists website (2009) Cognitive behavioural therapy (CBT) is most effective in patients who have had four or more prior episodes of depression, according to new research from The Netherlands. The study, published in the December issue of the British Journal of Psychiatry, suggests GPs could use the number of prior episodes to determine which patients are likely to benefit most from therapy and prescribe treatment accordingly). In another recent study, a comparison of a cognitive behavioural therapy (CBT) website with an information website for depression has found that after 6 months only the CBT website was significantly effective in reducing symptoms. After 1 year, both interventions were significantly better than no intervention (control condition). Research has shown that internet-delivered brief CBT may be effective in reducing depression, but it has not been clear whether these gains are maintained over time. The aim of this Australian study, published in the February 2008 issue of the British Journal of Psychiatry, was to see whether the benefits of internet-delivered brief psychoeducation and CBT were still there 6 and 12 months later, compared with a control condition, in which participants were asked questions about their lifestyle. Summary In summary, CBT is the treatment of choice in the NHS for moderate to severe depression and having reviewed all of the benefits and limitation, read from the critics and the ambassadors, the writer feels that there is still much to learn and evaluate in the treatment of depression. Whilst the results so far have appeared to show that CBT is very effective in the treatment of moderate to severe depression, there are large groups of people that will not benefit from this treatment, e.g. young children, those with personality disorders, late-life depression suffers. The writer suggests that there is not a universally acceptable treatment for all that some treatments will work for some people with some therapists and other treatments will work for others with another therapist the willingness of the client to seek help, play their part in their recovery alongside their chosen therapy will help some of the people, some of the time. But what about in the longer term ? Is this a sticking plaster over a gaping wound ? CBT can help in the here and now, but relapses can occur as the root of the problem if it is in the past is not usually discussed in a CBT session, which is focussed on the present. While the costs of depression to individuals, families and businesses are huge, the writer feels that the government, through the NHS has made very positive steps to try to assist people living with depression by welcoming the use the talking therapies. As more studies are commissioned in the future, new information will be gained and new decisions made based on this. For the moment, embracing the talking therapies is a very good step in the right direction and it is hoped that other therapies will continue to be evaluated so that patients of the future would have a choice of talking therapies, including CBT, but also others like life coaching, NLP and hypno-psychotherapy.

Dred Scott v. Sanford :: American History, Slavery, Freedom

Dred Scott, an African American man who was born into slavery, wanted what all slaves would have wanted, their freedom. They were mistreated, neglected, and treated not as humans, but as property. In 1852, Dred Scott sued his current owner, Sanford, about him, no longer being a slave, but a free man (Oyez 1). In Article four of the Constitution, it states that any slave, who set foot in a free land, makes them a free man. This controversy led to the ruling of the state courts and in the end, came to the final word of the Supreme Court. Is he a slave or a free man? Being born into slavery meant that Dred Scott had been exchanged from owners to owners (Knappman 16-17). His first owner, the Blows, died, and before their death, they sold Scott to Dr. Emerson. Dr. Emerson soon gave Scott away to his wife’s brother, Sanford (Knappman 16-17). Scott tried to buy his freedom away from Dr. Emerson’s wife but she just wouldn’t accept (Dred Scott Decision 1). Since Scott moved from place to place as a slave, he was able to go to Illinois, which was a free state (Richie 40). Because of the Constitution, Scott used his rights to sue Sanford claiming that he was a free man (Richie 40). With this in mind, it lead to arguments about both parties, the prosecuted and the defendant. With the help of the antislavery lawyers, they were able to assist the prosecution, Dred Scott, with his court case (Dred Scott Decision 1). Unfortunately, in the first trial, Scott lost due to the reason of not having enough evidence (Dred Scott Decision 1). Scott, determined to get his freedom, was given the chance for a second trial (â€Å"Dred Scott Case Collection†). Their main argument, about Sanford violating his Fifth Amendment rights, made them win their case in their second trial (Justia 1). The Fifth Amendment mentions that a person’s life, liberty, or property cannot be taken away without due process of law. They were taking away Scott’s liberty, but he deserved to be free because he was taken to a free state (Dred Scott Decision 1). Does this whole controversy end there? With Sanford losing in the second trial, it did not just end there. Sanford’s sister, Mrs. Emerson, appealed and because of that, it went to the Missouri Supreme Court (â€Å"Dred Scott Case Collection†).

Benzathine Benzylpenicillin

There are many people around the globe who would benefit from an injectable drug designed to release small amounts of medication over the course of a month. This is particularly necessary for people suffering from bacterial meningitis as they are required to receive injections on a regular basis. Additionally, there are countless other populations that would benefit from the availability of injectable medication. This type of medication dispension is useful for third world populations since they don’t have access to doctors on a regular basis.An injection that lasts for one month would ensure that these people were receiving necessary medication on a regular basis. At the same time, an injectable form of medication increases patient compliance since they are only responsible for getting the injection once a month instead of on a more regular basis. Similarly, injectable forms of medication allow patients to receive constant therapeutic levels of drug maintenance that ensures t hey get well.Finally, making medication available in injection form eliminates the need to refrigerate drugs and also reduces the number of trips a patient must make to a clinic to receive necessary medication. Therefore, this researcher aims to look at benzathine benzylpenicillin and its usefulness as an injectable drug. The lab already purchases benzathine benzylpenicillin but it is not in pure form. As a result, the job of this researcher would be to coat the benzathine benzylpenicillin with different polymers in order to slow down the dissolving process.If successful, this process would improve the lives of sick people all over the world who are required to receive frequent doses of penicillin. Penicillin is known to be unstable in liquid formations (Ogunleye, et al, 2004). Therefore, the first goal this researcher would have is to work with one type of polymer that uses heat rather than water. This polymer will be used to coat the penicillin so particles will not clump up. It i s essential to develop a way to keep penicillin particles from clumping so they can be released on a consistent basis after the initial injection.Further, benzathine benzylpenicillin will be injected using a needle and PVA is hydrophilic so clumping must be avoided in order to successfully inject the medication. The polymer this researcher will use is called polyvinyl alcohol. Establishing a way to prevent penicillin from clumping will contribute much to the research being conducted around the possibilities and benefits of using injectable benzathine benzylpenicillin. The second aim this researcher has is to develop a way to slow down the dissolving process of the benzathine benzylpenicillin in order to ensure that it releases constant dosages for an entire month.The main goal in slowing the dissolving process is to achieve a minimum level of concentration in order for the drug to be effective at a low level for a very long time. Discovering a way to slow this process is essential f or may patients, particularly those suffering from bacterial meningitis because benzathine benzylpenicillin cannot be given orally as the gastric acid and absorption of the intestinal tract is too slow to deem the oral form of the drug effective (Shaheen, 2004).There are several steps this researcher will take in preparing penicillin to be coated in order to make an injectible form of benzathine benzylpenicillin successful and worthwhile. After successfully determining the polymer concentrations that would be most effective, this researcher would use a fluid bed coater to apply the polymers to the penicillin. A fluid bed coater looks like an upside down bottle where the drug particles are dried as they travel in a clockwise circular motion. The penicillin will go into the machine and the polymers will go into a spray gun.The penicillin will be blown up into the upside down bottle and as it passes the spray gun it will be coated with the two different polymers. The inside of the bott le is hot so that the penicillin can dry before being sprayed with the polymers subsequent times. This process goes on until the researcher stops the machine. This allows the researcher to control how much polymer is allowed to coat the penicillin. The final step in this process is a dissolution test on the polymer coated penicillin. This researcher will place the penicillin in water (used as a medium of blood) and stir until dissolved.Then, this researcher will use a visible spectrospectry to determine the concentration of the drug in the water. This process allows the researcher to figure out how much of the drug was dissolved based on the amount of polymer coating the penicillin. In order to calculate the exact concentration, a sample of the water is placed in a cubbet and a UV light is shined on the sample. Concentration rates are determined based on how much light is able to come through, what type of light is coming through and the wavelength of the light coming through.Any gi ven molecule has a characteristic spectrum for a specific concentration of the drug, so by looking at the spectrum you can find drug concentration. This researcher is right for the job based on an in depth understanding of benzathine benzylpenicillin and the process it must go through to become safe and effective as an injectible drug. Additionally, this researcher is enthusiastic about the possibilities such an injectible drug will have to positively impact the lives of many people required to take constant doses of medication.The penicillin family of medication is an important tool in the arsenal for fighting illness (Wright, 1999). They are of low toxicity, they are highly effective and they are easily distributed through the body (Wright, 1999). This work won’t be accomplished quickly and there will be challenges along the way. However, this researcher is willing to persevere in order to discover new and innovative ways to make drug administration easier and more effectiv e for people required to take benzathine benzylpenicillin.When a correct mixture of polymers is discovered and dissolution is slow, this researcher will consider the project a success.

How to Change a Flat Tire

You can easily get sucker into paying more than fifty dollars for having a towing company change flat tire for you. Instead, you can save yourself money by doing it yourself. It is a simple process that takes less than half an hour. Most of the tools you need are already in your car. These tools include a Jack, a tire iron, a spare tire, and road flares. The first step is to set up the road flares. Flares are available at most department stores and are a very good idea to carry. Setting flares makes the car more visible, decreasing the chance of an accident while you are changing the tire. To properly set flares, you should have four of them. Take each flare and light it, following the directions on the package. After you light them, lay them on the ground in the following pattern. Lay the first one about fifty feet behind your car, and about four feet from the white line on the side of the road. Set the rest of the flares in a straight line, with the last one being about three feet from the driver’s side rear corner of your car on the white line. This will allow other drivers to see that there is an emergency, and allow them time to merge. The next step is to begin the tire change. To do this you must take the rest of the tools out of your car. The tire iron is probably in the trunk along with the spare tire. The car jack might be in the trunk, or it might be under the hood next to the engine. It depends on what type of car you have. Once you have all of the tools out, find the tire iron. The tire iron in most vehicles is a bent piece of steel flattened on one end, with a socket on the other. Use the flattened end to pry off the hubcap. Then use the socket to loosen all five lug nuts. Do not remove the lug nuts at this time because it will cause the car to fall. Once you loosen the lug nuts, you will begin lifting the car with the jack. There are only four places on the car where you can put the jack. They are close to the tires, and reinforced to hold the weight of the car. There are pictures and written directions on the side of the jack, telling you where to use it. Find the spot where the jack goes, and determine if the ground will support the weight of your car. If it might not, you will want to stick a board, or another hard object under the jack. This will allow you to jack up the car, even in the softest ground. Once the tire is off the ground about four to five inches, remove the lug nuts, and take the tire off. Take your spare tire, line it up with the lug bolts, and slip it on. Put all five lug nuts back on and tighten them as much as possible. It is easier to put the top ones on first, because this will keep the ire from falling off. Lower the car back to the ground, and remove the jack. Tighten the lug nuts as tight as possible. There is a special way to tighten the lug nuts, if you do not do it this way, your tire may be on the hub crooked. After tightening one lug, go directly across to tighten the next one, be sure to re-tighten all of the lug nuts at least four times. This will make your tire go on the hub perfectly straight. Then, put all of the tools away, and put your flat tire in the trunk. Before you go, read the spare tire to see if there is any speed limitations. Some car manufacturers design their spares to travel only at slow speeds. Check your tire for any specific regulations. If you do not abide by speed limitations, the tire could blow out, causing not only damage to the rim, but also possibly body damage to the car. How to Change a Flat Tire Donna Pierce ENG032 G02 02-21-2013 Illustration Essay First Draft Going back to College As a college student, all my fellow students are worried about what they will do for spring break. I, on the other hand, am trying to figure out what to do with my grandchildren. I have been out of school for 28 years. Being back in college is exciting, but it can also be very stressful too. So many things have changed since I was in school. For instance, the subjects are a lot harder than 28 years ago.For example, the math classes with algebra are nothing like the algebra that I learned back in the day. Also, all of our homework has to be done online. We didn’t really use the internet back then. Furthermore, it’s really nice getting to meet new friends that are my age and older. For instance, we all get together and have study groups to try to help each other out. To sum it up, going back to college at an older age has its advantages and disadvantages.The subjects are different to s ome extent, but I just have to work that much harder to understand and learn the internet better. It’s really nice having friends that you can get together with as a study group to help each other understand and try to accomplish our goals. I feel that going back to school will help me learn that it doesn’t matter how old you are, you still can accomplish your goals in life if you put forth the effort.
