Extacy the Drug Essay examples -- essays research papers
In the past 20 years, chemically made drugs have been increasing in popularity among drug users all around the world. Although "old" drugs like marijuana and cocaine are still used among addicts, chemically prepared drugs like Extacy and Angel Dust are becoming more common and desired by drugs users today. It is also true that these drugs contain a much larger percentage of life threatening substances. Although Extacy is a dangerous drug, it has been excessively rumored by the media to be the "Killer Drug from Hell". This is unfair though, because the statistics show that deaths due to Extacy are rare and can usually be prevented by the user. Over the past years, it has adapted many other names including E, XTC, X, Ecstasy, MDMA, MDA, Dove, Love, and Adam. (1) Extacy is 3,4 methylenedioxymethylamphetamine, (MDMA). It was invented in 1912 to help in medical science, but was used very rarely. In the 1970?s, it was also said to have been introduced as helping in psychotherapy. It was first used as a street and illicit drug in the mid 1980?s. MDMA is a part of the phenethylamines family of drugs. It is very similar to another drug in this family known as MDA (3,4 methylenedioxyamphetamine). MDA is basically a heavier form of MDMA, where the effects of the drug can last longer, and the symptoms can get more severe. MDMA is also close to MDEA (3,4 methylenedioxyethylamphetamine) which is basically a lighter form of MDMA, where the effects last less and the symptoms are less powerful. It is proven to be extremely dangerous to those suffering from asthma, epilepsy, diabetes, hypertension, glaucoma and pregnant women. (1,3) Extacy is a powerful mood changer, which lets the user act the way he/she wants without having to... ...om the dancing is recommended for the heart to give itself a break. For the body to recover from Extacy, lots of Vitamin C and Calcium are needed. Also, sleeping and eating is another way of recovery, since a lot of energy is lost from the dancing and being hyper while at the peak. (1,3,4,7) Extacy has been one of the drugs most desired by the public in the past decade. It is known to carry a risk factor along with it, but this factor seems to have become exaggerated by the media to certain levels. Although it is no "Killer Drug", Extacy has caused some deaths. Most of these deaths could have been prevented if the users had been careful. After saying all this, I must state again that Extacy is among the Class A group of drugs. This group contains the most dangerous drugs, and that is why all people are recommended to stay far away from this drug as possible.

Strategy Sheet Table of Contents Page Aim of Study Location of Maps Method of Data Collection Presentation of Data Conclusion Bibliography Appendix Aim To identify and examine whether residence of Ensom City, Spanish Town are aware of the origin, development and the precautions to be undertaken during a hurricane. Method of Data Collection How? Fifteen (15) questionnaires were issued by the researcher to 15 persons of Ensom City. They were distributed to every other house in which four (4) was male and sixteen (11) was female. Also Secondary Sources were also consulted for relevant data example internet and textbooks. N. B A copy of Questionnaire is provided in the appendix (1a) Where? The Study was done in Ensom City, Spanish Town. When? The School Bases Assessment (Sba) was conducted on October 24 2011 between the hours 1pm to 5 pm (in hurricane season). Each questionnaire was issued for two days then collected back by the researcher to continue further studies. Presentation of Data According to ucar. du a hurricane is an intense, rotating oceanic weather system that possess maximum sustain winds of exceeding 119km/h (74mph). It is formed and intensified over tropical oceans regions. 11 of the 15 residence agreed that hurricanes are found in the tropics. Figure 1: showing what region hurricane is developed by residence of Ensom City. In Figure 1 it shows how much of the residence are aware of the formation of hurricane. It shows that 11 of the residence chose tropics for the formation region which was correct because hurricanes do develop at these regions, however the other four chose temperate and fringe zones. Figure2 showing the formation of hurricane chosen by the residence of Ensom City Figure2. Shows the amount of residence that agreed to each way how hurricanes are formed. The chart only contains the number of persons who agreed to each given formation. It shows that five of the residence agreed that hurricane needs warm area to make it thrive or to become stronger which was indeed correct as said in Longman Geography for CSEC. The chart also show that four residence chose that hurricane depends on the spinning of the earth and ten agreed that hurricanes needs winds that change direction and increase speed. Also five persons choose that hurricane must have atmosphere that cools fast. Figure 3 showing the precautions chosen by residence of Ensom City, Spanish town that is to be undertaken during a hurricane. Figure3. Above show the precautions that are to be undertaken during a hurricane. It shows that the entire residents are aware that they are to stay in during a hurricane, stay away from windows and doors during a hurricane but 7 are aware to watch down power lines etc. Conclusion The research had showed that some amount of the residence of Ensom City Spanish town is aware of hurricane development origin and precautions . This is proven because of the response on the questionnaires. The awareness of Residence on the origin of hurricane The questionnaire shows that 73. 3% of the residence questioned is aware of the origin of hurricanes. They agreed that hurricanes are formed in the hot regions of the world. The awareness of Residence on the development of hurricane The questionnaire shows that about 50 % of the residence questioned is aware of the development of hurricanes. Hurricanes needs a warm area to develop The awareness of Residence on the precautions to be undertaken during a hurricane The questionnaire shows that about 90 % of the residence questioned is aware of the precautions to be undertaken during hurricanes. The agreed that they are to stay in, stay away from windows and doors and also to watch out for downed power lines Bibliography Paul Guiness et al, Geography for CSEC Nelson Thorns, 2008 Marolyn Gentles et al, Longman Geography for CSEC, 2006 Appendix

Cement Clinker Manufacturing Process Manual
What is cement? Cement is a fine powder which sets after a few hours when mixed with water, and then hardens in a few days into a solid, strong material. Cement is mainly used to bind fine sand and coarse aggregates together in concrete. Cement is a hydraulic binder, i. e. it hardens when water is added. There are 27 types of common cement which can be grouped into 5 general categories and 3 strength classes: ordinary, high and very high. In addition, some special cements exist like sulphate resisting cement, low heat cement and calcium aluminate cement.The quarry is the starting point Cement plants are usually located closely either to hot spots in the market or to areas with sufficient quantities of raw materials. The aim is to keep transportation costs low. Basic constituents for cement (limestone and clay) are taken from quarries in these areas. A two-step process Basically, cement is produced in two steps: first, clinker is produced from raw materials. In the second step cement is produced from cement clinker. The first step can be a dry, wet, semi-dry or semi-wet process according to the state of the raw material.Making clinker The raw materials are delivered in bulk, crushed and homogenised into a mixture which is fed into a rotary kiln. This is an enormous rotating pipe of 60 to 90 m long and up to 6 m in diameter. This huge kiln is heated by a 2000à °C flame inside of it. The kiln is slightly inclined to allow for the materials to slowly reach the other end, where it is quickly cooled to 100-200à °C. Four basic oxides in the correct proportions make cement clinker: calcium oxide (65%), silicon oxide (20%), alumina oxide (10%) and iron oxide (5%).These elements mixed homogeneously (called ââ¬Å"raw mealâ⬠or slurry) will combine when heated by the flame at a temperature of approximately 1450à °C. New compounds are formed: silicates, aluminates and ferrites of calcium. Hydraulic hardening of cement is due to the hydration of these compounds. The final product of this phase is called ââ¬Å"clinkerâ⬠. These solid grains are then stored in huge silos. End of phase one. From clinker to cement The second phase is handled in a cement grinding mill, which may be located in a different place to the clinker plant.Gypsum (calcium sulphates) and possibly additional cementitious (such as blastfurnace slag, coal fly ash, natural pozzolanas, etc. ) or inert materials (limestone) are added to the clinker. All constituents are ground leading to a fine and homogenous powder. End of phase two. The cement is then stored in silos before being dispatched either in bulk or bagged. What is concrete? Concrete is a solid material made of cement, sand, water, aggregates and often with admixtures.When fresh, it has a certain workability and takes the form of the mould into which it is put. When set and hardened, it is as strong as natural stone and resists time, water, frost, mechanical constraints and fire. Typically, concrete is the essentia l material used in all types of construction [residential (housing), non-residential (offices) and civil engineering (roads, bridges, etc. )].

The Island of Lauropia
Secluded in the middle of the Atlantic Ocean, is a place called Lauropia, a wonderful society. It is always peaceful and nothing bad ever happens on the island. The island's air is always fresh and free of any toxins or pollution. Temperature on the South side of Lauropia is always warm with no humidity present. On the North side of Lauropia the weather is always perfect for winter activities, the temperature is just cold enough for the snow to fall. The North side of the island is full of steep, snow-covered mountains that are perfect for skiing. On the South side of the Lauropia clean, sandy beaches cover the land. The ocean water is crystal clear and warm. Lauropia is the perfect place to live. On the island every person would be treated as an equal. No one person would think or act like they were better than someone else. There would be no racism present, all types of people would reside here and get along together. It wouldn't matter if you were African American, Caucasian, Asian, Spanish, Mexican or any other race each and every individual would treat each other the same. Whether a person was heterosexual, homosexual, or bisexual wouldn't matter. Lauropians wouldn't judge each other by their appearance or whom they interacted with. There would be a diverse amount of different religions that would not criticize the other religions for their beliefs. Once a month all the different religions would get together at the island community building and congregate together to discuss their viewpoints and thoughts on each faith. The Lauropians would be involved in a wide variety of sports and leisure activities all year long. This would be made possible because of the extreme temperature differences on the North and South sides of the mountain. The North side would always be cold so the citizen could go skiing and snowboarding at the Lauropian Mountain Resort. The resort would offer a wide variety of different leveled slopes for the skiers on one half of the mountain. On the other half of the mountain there would be a Snowboard Park consisting of a slopes and half pipes strictly for the snowboarders. A snow tubing park would also be available for any whom has interest in snow tubing. There would family tubes and single tubes available for use. For all the snow mobilers on Lauropia, The Lauropian Mobile Park will be open for their riding enjoyment. All these activities and more on North Lauropia will have minimal charges to take advantage of the facilities. On the warm and sunny South Lauropia, the beaches will be clean and free of charge for all citizens. The beaches would have volleyball courts open to anyone. At the piers there would be docks where people could rent Jet Ski's, Speed Boats, Yachts, and Party Boats for their recreational pleasure. Sidewalks and paths would be on hand for Lauropians to roller blade, skateboard, ride bikes, and run, jog, or walk. Boating trips would also be available that take groups out in the middle of the ocean to scuba dive and snorkel. Throughout the whole island shopping centers, eateries, and sports complexes of all types will be accessible. Any store imaginable would exist for the Lauropians to shop for their wants and needs. The women would be in shopping heaven with the amount and variety of stores available to them. The amounts of places to eat would be incredible. They would range from places like Burger King and McDonalds, to Chi Chi's and Lone Star, to five star restaurants. Any type of food that a person had a craving for would be accessible. Sports Complexes would be placed all over the island for Lauropians to participate in any athletic event that they enjoyed. There would be football, baseball, field hockey, softball, soccer, and lacrosse fields. Indoor and outdoor courts for tennis players would be accessible. If there were any sports that a person or group of people would want to play and the facilities were not available the Lauropian Sports Board would do their best to make them available. The Lauropian Society would always try to make the island enjoyable for each person. Schooling would be one of the most important aspects of life on the island. It will be required for all citizens to start their education at elementary school level and continue up to collegiate level. It would not be required, but if the parents wanted to start sending their children to nursery or preschool the facilities would be open for use free of charge. All schooling on the island would be free of charge because education is of great importance to the people of Lauropia. The schools would administer the best education possible. There would be a large variety colleges available for students to choose from depending on their individual or dual major. If a person decided that they did not want to finish their schooling, being banished from the island would punish them. When and if the person decides they want to come back to island to finish their education the school board will have a meeting and decide if that certain person deserves to be let back on the island. On most occasions the student will be allowed to come back. Once a person graduates from college and gets a job, if they decide they want to go back to college to further their education, the company that they work for will usually give them funding for it. Students will be required to go to school for nine months out of the year. Altogether students would be required to attend seventeen years of schooling. In order to insure that the students would be getting an excellent education the teachers would have to take a Teaching Exam every five years. If the teachers fail to complete the requirements and the written section of the test they will not be permitted to teach for one year. After the period of time is up the teacher may retake the test and if he or she passes it, they will then be allowed to teach again. Teachers would also be required to go back to college annually and take two courses to broaden their knowledge. All measures would be taken that would be necessary to maintain the finest quality of education for Lauropians. The citizens of Lauropia would be able to make up their own laws and rules. Each year the members the government would sit down and revise the laws from the years before if necessary. Each community on Lauropia would have representatives that would go around and take ideas and thoughts on how the island could be changed and run to make it better place to live. Laws would never be passed if a large number of people on the island disagreed with them. The main concern that the government would have is the Lauropians happiness.

Comparing bluetooth technology and infrared Essay
Comparing bluetooth technology and infrared - Essay Example The following paper analyses the relative advantages of all three. Bluetooth is an always-on, short-range radio based technology that resides on a microchip. Controlled and moderated by the Bluetooth Special Interest Group, this short range wireless communication technology started off as a utility to enable laptop users to make calls via a mobile phone. It was commissioned by the mobile phone company Ericsson but soon started spreading. The concept behind the technology is fairly simple. It uses a 2.4 GHz band to connect blue tooth devices that may be within ten meters of each other to share at up to 720 Kbps (How Bluetooth Works). This technology can operate with many users to create a piconet, further networks of which allow larger communication. Safety and privacy is assured through encoding each link, thus not allowing third parties to access the data being transferred without the relevant PIN code or authorization. As a radio broadcast communication system is being utilized here, line of sight communication is not a problem in the case of Blu etooth technology. This leads to many possible applications of this technology. First of all wireless communication between various devices such as personal computers in small network or between mobile phones or between a personal computer and its connecting devices such as mouse and keyboard can be employed. This leads to easy communication without the use of long wires that can easily occupy useful space and is unseemly to the eyes and in cramped computer rooms. Game consoles use this technology to allow communication between the processing machine and the controllers. Dial-up internet facility on Personal Digital Assistants makes use of Bluetooth as well. Seeing the range of applications of this technology, one can surmise that it has some obvious benefits. First of all, it replaces serial equipment making use of wires spreading everywhere and allows easy communication with devices near it. There is the further advantage of mobility, where the user is not required to be tethered to the electronic device to be able to use a Bluetooth active device. Such practical advantages make its use worthwhile and convenient. Unlike the Infra Red technology discussed later, it does not require the connecting devices to be in line of sight which gives it an advantage in terms of range over Infra red enable devices. However, there are many disadvantages as well. As many applications as it has, Microsoft chose to not include Bluetooth support in its new operating system as it claimed there were still not many Bluetooth enables devices that required Windows support (How Bluetooth Works). This limits its uses for personal computer users who make use of the Windows operating system. Furthermore, the microchip that is required for Bluetooth technology can be labeled relatively expensive. This presents a challenge to its use in mobile phones which are hugely competitive in terms of prices and companies may see costs rising. This diminishes its extended use by the mobile phone industry unless its cost drops. There is also the problem of security. A number of weaknesses have been pointed out in Bluetooth's pin number based production of a device's initiation key. This can lead to possible cracks in security, allowing a third

Roman and Mongol Conquests Essay Example | Topics and Well Written Essays - 750 words
Roman and Mongol Conquests - Essay Example The leaders crafted policies that ensured continued survival and expansion through ruthless crusades and strategic treaties. It may also have been their dogged determination and ability to rise from the ashes of defeat on to victory as was the case for Rome (Livy, 1905). Monarchies and ruling hierarchies were established along either blood or loyalty lines depending on which strategy served best. At times, it included both cases, for instance, in the case of Genghis Khan. In each case, the subjugation of conquered territories through force, surrender or the brokering of peace treaties fortified the might of the Empire and gave strength and momentum for expansion. During their various conquests and expansion under various rulers, initial wars were fought with neighboring nations or tribes. Campaigns were sent out in all directions to conquer new lands for the Empire. The rise of the Mongol Empire began at a time when the usually dry and cold steppes of Central Asia got their most favorable conditions for over a hundred years. Thus, the rapid growth in numbers of battle horses, other livestock and food supplies (Burgan, 2005). The growth may have enhanced the military ability of the Mongols. The strategic placement of Rome gave it unrivaled dominance of the Mediterranean Sea and allowed it to encompass peripheral lands was its greatest advantage (Livy, 1905). Won wars always led to subjugation of conquered peoples. While Rome imposed measures such as payment of taxes and tributes to Rome, Mongols approached matters from a platform of unification by making conditions more favorable for the People. Genghis Khan united rival tribes by banning fighting among Mongols, successfully ending civil strife. He also forbade trading of women, pilfering of otherââ¬â¢s property and desiccation of animal populations during the breeding season. According to Burgan, He shared his bounty among all crusaders and their

Abortion Essay Example | Topics and Well Written Essays - 1750 words
Abortion - Essay Example Nothing is more demoralizing than a life without freedom. A life in which one can be compelled into parenthood is just such a life. Rape is among the most reflective rejections of liberty, and convincing a woman to accept a rapist's child is a murder or an attack on her humanity. How diverse is it to force her to remain pregnant and become a mother just for the reason that efforts at birth control by chance failed? From her standpoint, the pregnancy is also unwanted. From the point of view of the fetus, how the pregnancy began certainly makes no difference. If compelling a woman to persist a pregnancy that will just about surely kill her is not permitted, how different is it to force her to maintain a pregnancy that will almost certainly shorten her life? Or a pregnancy that will leave her life a shambles? Are there means of approaching issues like abortion that evade pitting these absolutes against one another? Approaches of choosing that uphold respect for the deepest principles on both sides of the equation? Ways that face the authenticity of sex and power that trigger the struggle? Analysis One of the famous cases in the American history has been the case of Roe V. Wade. It was a case in which the Supreme Court said that except in narrow state of affairs, the Constitution of the United States does not allow the government to interfere with a woman's right to desire abortion. Roe v. Wade is various things. It is a legal verdict by the Supreme Court; a rallying cries for both sides in the abortion debate. But it is in addition, and was in the beginning, a completely human story, one that has become by now common to numerous as a story similar to other stories repeated all over the United States daily. It seems telling that in Roe v. Wade both the woman on one side of the "versus" ("Roe") and the fetus on the other (stand for by Wade) are anonymous. In much of the debate over abortion in our society, one side or the other is condensed to ghostly secrecy. Many who can willingly imagine the concrete humanity of a fetus, who hold its picture high as well as weep, hardly see the woman who carries it and her human dilemma. To them she becomes an all but invisible abstraction. Numerous others, who can willingly imagine the woman and her body, who cry out for her right to control her fate, hardly imagine the fetus within that woman and do not envisage as real the life it might have been permitted to lead. For them, the life of the fetus becomes a similarly invisible concept (Tribe & Norton, 1992). America is at a junction. In the year 1989, the sixteen-year era of judicial defense of legal abortion rights that started with the Supreme Court's 1973 decision in Roe v. Wade ended with that Court's five to four decision maintenance certain state regulations of abortion in the case of Webster v. Reproductive Health Services. A right that, ever since the time of Watergate and Vietnam, had been kept by judges from the horseplay of local politics-the woman's right to make a decision for herself whether to finish a pregnancy-is now focused to regulation, and perhaps even prohibition, by our chosen legislature. A right that numerous Americans took for granted is now in a real sense up for grabs. Anyone who doubts that this is the meaning of Webster needs look no further than the morning newspaper. As the 1990s dawn, the nature of politics in America is altering daily, and the gloom of the question of abortion rights grows, with extensive worth for our society. Even as the public program is prolonged to deal with such new questions as the right to die, no matter intimidates to split us politically in quite as influential a way as the abortion issue does. Our national institutions are braced for an
