Teenage Pregnancy Essay In years past teen pregnancy created problems in several countries. However in the United States among teenagers, teen pregnancy rose, but there was no help from programs like the National Geographic’s channel, and Teen Mom that aired on MTV. Individuals saw a version of what might have been with cameras rolling, however if the cameras are not rolling then life takes on a different meaning.

Radioactivity In Ionisation Smoke Alarms Environmental Sciences Essay

Radioactivity In Ionisation Smoke Alarms Environmental Sciences Essay In this coursework, I will be discussing the role of radioactivity in ionisation smoke alarms; I will focus primarily on the main radioactive substance used in smoke alarms, americium 241, and will analyse its effects as well as its half life. I will also analyse a variety of data based on smoke alarms, and finally, I will discuss the advantages and disadvantages of smoke alarms. In smoke detectors, Alpha radiation is given out. Alpha particles are made of 2 protons and 2 neutrons. This means that they have a charge of +2, and a mass of 4. Alpha particles are relatively slow and heavy. Alpha emitters must be used for smoke detectors since alpha particles ionise air the most, are mostly likely to be absorbed by cells and are least penetrating. Gamma rays and beta particles easily pass through air without causing ionisation, Beta particles are absorbed by a thin sheet of Aluminium and Gamma is absorbed by either concrete or thick lead. The radiation given out from the smoke detector is essentially zero and in any case very much less than that from natural background radiation. This is the radiation which all around us. The alpha particles  are absorbed within the detector. The small amount of radioactive material that is used in these detectors is not a health hazard and individual units can be disposed of in normal household waste. However, Alpha radiation is most dangerous inside the body because it is most likely to be absorbed by the organs whereas Beta and Gamma radiation is more dangerous outside the body because the skin cannot stop them. Americium-241 is dangerous if it is taken into the body in soluble form. The data which I mainly used for my coursework was from www.communities.gov.uk. I think this website is reliable and valid because it is a government website. It has not been created for the purpose of sale so it isnt biased. However there are a few problems with this website. The problem lies in the data which shows how the % of homes with smoke alarms has changed between 1988-2005. This data is unreliable and invalid. It is invalid because they change from smoke alarm ownership to working smoke alarm ownership in conclusion to that it also has data missing from some years. It is not as valid as it should be because it not the same as what was being looked at in the beginning. But as for the rest of the information, I think it is reliable and valid because it is a government website, not any website just put up on to the internet. The way in which we could make sure that the data we have it valid and reliable is by comparing them with other results from other sources. By doing this we would be able to see if they are similar or they are different and we would be able to find out if they are correct or not. The results which I got could be improved if they were collected in a number of different ways. For example data could be collected from the history of the emergency services, data could also be collected by handing out questionnaires and surveys or even collected via the phone. Advantages and Disadvantages of Smoke Alarms There are many benefits of a smoke alarm and many disadvantages. Below are some advantages of a smoke alarm. Firstly the most important benefit of a smoke alarm is that it saves lives. Smoke alarms are a powerful and effective fire safety technology. The smoke detector also allows the emergency services to react quicker so they are able to get to the fire quicker and save lives. The most important thing is the life of a person. Besides this, a smoke detector also saves money and property. Some people may have money stored at home. For these people it would be a great loss if they were to lose everything in a fire. With a smoke detector, a person is able to quickly put out the fire so a lot of the property does not get damaged. Another advantage is that the americium-241 is very sensitive. Ionization smoke alarms respond first to fast flaming fires. A flaming fire consumes flammable extremely fast, spreads rapidly and generates considerable heat with little smoke. It responds very quickly to small amounts of smoke. Americium-241 has a half life of 442 which is not too long or too short. It is just right. If it had a long half-life then it wouldnt have to be replaced very often but it would stay dangerous for a long time. If it had a short half-life then it would fall to safe level quickly but it would have to be replaced very often. The Americium is just right, not too short or too long, in the middle. One advantage is that to have a smoke detector reduces the insurance cost. This is because a house which has a smoke detector has less chance of burning down because the smoke alarm will detect the fire so the occupants are able to put it off. For this reason there is cheaper insurance for the house which has a smoke alarm. Finally, smoke alarms are very cheap. They are even free for many houses but for some people who have to buy it, it is of a very low price. With the advantages, there are also disadvantages of smoke detectors. Below are some disadvantages of smoke alarms. The biggest disadvantage is that it contains a very small amount of radioactive material. These devices are probably not a problem unless they burn, in which case the Americium would be released in particulate form an inhalation hazard. Another big disadvantage is that it is a bit too sensitive. It can be vulnerable to nuisance alarms if placed too close to cooking. It goes off many times especially if it is kept near a kitchen. This can be very annoying especially if it happens repeatedly. One disadvantage is that because there are many smoke alarms which give out radiation in this country, they will be radioactive for 1000 of years. The radioactivity in the environment will increase. The disposal of this type of smoke alarm is very harmful, when the building is demolished and new buildings are made, the smoke alarm still emits radioactivity which is not good for the environment. Finally, another disadvantage is that it works on battery and after a long period, the battery runs out. Therefore, smoke detector stops working so the batteries have to be replaced. Overall, I think that smoke detectors are beneficial because it could save a persons life if a fire was to occur and its also very cheap to buy but it has it drawbacks that it emits radioactive material, however the advantages outweigh the disadvantages.

Urban Legend of the The Monsters Chase Essays -- Urban Legends

The Monster's Chase Background and Story It was late on a weekday night a couple of weeks ago when I was unexpectedly told an urban legend by a friend of mine in my dorm. I brought up a report I had to prepare about a local urban legend and my desire to find someone who knew a tale of the â€Å"Goatman,† a famous figure in folklore. My friend immediately recounted to me a story about a hairy monster that sounded rather similar. He had been told the story by a member of his group one night at a youth hostel in Japan during an organized trip. The person who told him the story originally is from western Maryland. One night on this trip, we were in the hostel at night and one of the guys in the group told us a story about this monster. He said this actually happened to him. He lives out in western Maryland, further west and north than Montgomery and Frederick counties. He and his girlfriend had snuck out to a party one night and were returning when they decided to stop at McDonald’s to get dinner. They pulled over by the side of the road they were traveling on, knowing that the McDonald’s was through a short tract of woods on the side of the road. About halfway through the woods a furry monster, black as space, with bright red eyes and sharp white teeth [embellishes features with gestures], appeared and started chasing them. They turned around and sprinted back to their car. They got inside, and the monster caught up and started banging on their doors and windows. The car started, and they burned rubber driving off, but they noticed that another car had pulled up [and par ked] behind theirs. The monster man got into his car and also peeled off, chasing after them [performs hand motions for two cars]. After a couple m... ... whim and rather than drive to it, pull over and choose to cross through woods because it saves them time. They’ve been out having fun, and the dangers of dark woods by a lonely road at night don’t concern them. This carelessness nearly costs them. The disappearing tire tracks the next day help to add to the message, they could’ve been killed and disappeared, and the killer wouldn’t have even left a trace.

War and Peaceful Fables :: Stories War Peace Essays

War and Peaceful Fables War stories, fantasy stories, sci-fi and simplistic fable stories, the list trails on like fans behind a famous actor. From books or movies to computer games and music videos, the element of story penetrates a broad array of interests; the public longs for engaging stories and seeks them in any form they can. Keeping this in mind, please do not be shocked when I state that gruesome war stories and simple fables are, in principle, one in the same. Of course, I dont deny that one form of story may be more preferable for readers. However, we can know that the meaning of story (a written work that shows character and the motivations that spring from it) puts such extremely different stories and genres on the same plane. In The Things They Carried, Tim OBriens mastery of the concept of character comes through to us clearly. He portrays Lieutenant Jimmy Crosss inner struggles and unpredictable actions in such a way that we can identify with himeven though the lieutenants character comes out under the stress of war, and ours may not. Just like many an average person, Lieutenant Cross adds to his burden, physical and mental, by carrying pictures and letters from his love, Martha. He knows she really doesnt love him, but, from the pressure of war, he turns by default to the comfort of his far away love, countering the harsh reality. The second sentence of the selection of The Things They Carried begins with, They were not love letters, but Lieutenant Cross was hoping (706). This quote shows what the letters meant to Cross, and why he carried them. He and the other men cling to material things in this mannerwhether it be love or dope, tranquilizers or too much ammunition, or even slingshots and comic book s. Doesnt this seem a silly thing for soldiers to do? Maybe. But their reactions to war are certainly realistic. OBrien continues to expand character throughout the piece. In the lieutenants mind, the pressure and even pointlessness of war grows with its morbidity and loss. But it was not a battle, just an endless march without purpose (713). OBrien continues this prose with revealing that the men would often discard things. Purely for comfort they would throw away rations (713). But no matter how they discarded the objects that they needed physically, it was so difficult to shed the emotional weight They carried all the baggage of men who might die (716).

Chris Layton 12 September 2013 Block 1 Rough Draft Drugs & Athletes During the advancement of technology, athletes have been able to get powerful drugs that help them during physical activity. These drugs are also banned by the World Anti-Doping Agency (WADA). They use these drugs to give them a competitive edge to keep up with the competition. Some athletes have distinctive trait that some do not like having a gene that helps them perform like the ACE gene helps perform in long distance events. Other athletes that compete have to use performance enhancing drugs (PEDs) to be able to keep up with them and have a chance to win. Performance enhancing drugs, including blood doping, stimulants, and human growth hormone, should be prohibited because of moral and ethical concerns and the personal consequences to athletes. Performance enhancing drugs have been used since ancient times. The use of enhancement substances for sporting events dates back to the ancient Greeks and ancient Maya. () Performance potions were utilized by the Greeks to increase their abilities and cocoa leaves were thought to be used by ancient Maya. () Today, athletes will go to many lengths to increase athletic ability, including: steroids, HGH, Amphetamines, and even animal or human organs just as the Greeks did in their time. () The most common performance enhancing drugs or treatment is blood doping, stimulants, human growth hormone (HGH), and anabolic steroids. Stimulants are a generic term to describe various substances that are ingested by athletes into the human body for the purpose of increasing alertness or general physical performance. Common stimulants that have been typically utilized by athletes in various disciplines are caffeine, amphetamines, a... ...drugs and go suspended for one and a half seasons. Performance enhancing drugs are not worth all the problems they can cause and definitely not worth your fans losing respect for you because they’re the ones who support you throughout your years. Overall, the negative effects of PED’s overweigh the positive effects of the use and abuse of them. The head of sports made the right move to ban, performance enhancing drugs, including blood doping, stimulants, and human growth hormone, should be prohibited because of moral and ethical concerns and the personal consequences to athletes. Performance enhancing drugs granted give you an edge over your competitor, but later in life you will regret using them because it’s effects will still be there rather you’re still on them or not. The World Anti-Doping Agency made the right move to ban all substances that harm yourself.

Intro to Rh Bill Essay

Introduction: Humans are naturally born governed with laws and that’s what we call the natural law. And as we, humans grow to become more intellectual, we generated our own laws and rules to govern our lives for better quality and discipline. But sometimes, there are laws or proponents that have gained different viewpoints among us as to its necessity, value, and morality. One of these is the Reproductive Health Bill. Almost over a decade has passed since the Reproductive Health Bill in the Philippines was for the first time proposed, now that the pursuance of the bill has gained its rebirth, still it has become a part of the national debate bringing about a wider division. The Reproductive Health Bill, popularly known as the RH Bill, Is this essay helpful? Upgrade your account to read more and access more than 650,000 just like it! get better grades is a Philippine bill aiming to guarantee universal access to methods and information on birth control and maternal care. While there is general agreement about its provisions on maternal and child health, there is great debate on its key proposal that the Filipino taxpayer and the private sector will fund and undertake widespread distribution of family planning devices furthermore, 81% Filipinos are Catholics, the Catholic Church exerts a strong influence in public life. Its staunch of opposition to the bill has drawn the ire of non-Catholics and Catholics alike who support the bill, and they invoke the principle of separation of church and state to stop the church. Passage or non-passage of the bill has negative implications depending on the views.

John Dalton and Atomic Theory Outline and Sources

John Dalton and Atomic Theory John Dalton was a British scientist who made important contributions to science and to the atomic model specifically. I. Experiences in his life that led to his interest in science and the study of the atom A. Education and teaching career brought him in contact with amateur meteorologists B. Mentors and meteorology directed his interest toward air pressure and properties of gaseous elements C. Study of elements led to interest in components of elements and his atomic theory. D.This is the general path to his discoveries. However, no one knows specifically how he reached most of his conclusions about atoms. II. Work on the atom and its contribution to the modern atomic model A. Lavoisier’s Law influenced Dalton’s assertion that atoms cannot be created, destroyed, or subdivided. B. Proust’s Law of Definite Proportions led Dalton to his Law of Multiple Proportions C. He was trying to explain why water absorbs different gases in differe nt proportions. D. Contributions 1. All matter consists of tiny particles, atoms. 2.Atoms cannot be created, destroyed, separated into smaller parts or transformed into another element. 3. All atoms of the same element have identical weights, while atoms of different elements have different weights. 4. When elements react, their atoms combine in simple, whole-number ratios. 5. When elements react, their atoms sometimes combine in more than one simple, whole-number ratio. 6. When atoms combine in only one ratio, they are combining in a 1:1 ratio. III. Contributions which were eventually disproven and thus are not part of the modern model A.The idea that atoms that combine in only one ratio do so in a 1:1 ratio not only led him to wrong conclusions, but also caused his theory to be rejected for many years. B. Another mistaken idea was that atoms cannot be separated into smaller parts or transformed into another element. C. The assertion that all atoms of the same element have identica l weights, while atoms of different elements have different weights is inaccurate. IV. Conclusion A. His work was important and foundational to modern atomic model. Sources [1] â€Å"John Dalton (British Scientist): Atomic Theory. Encyclopedia Britannica Online. Encyclopedia Britannica, n. d.
