In a 2012 study published by the Journal of American College Health, by senior year, Adderall and other prescription stimulants are offered to two-thirds of college students. Furthermore, about 31 percent are taking the drug in hopes to enhance their concentration to get better grades (Zadrozny 2013). Students who take Adderall that don’t have ADHD report that they have a increased sense of focus, motivation, and concentration, which are all the ingredients you need to have for a successful all-nighter to help on providing an added boost before an exam. With characteristics such as difficulties in focusing, reasoning, problem solving and planning, ADHD is a neurobehavioral-based disorder and is associated with an insufficient amount of dopamine (Student Health: Drug & Alcohol Abuse among College Students 2015). Adderall is enticing to students because they believe it can help them perform enhance their academic skills. On the other hand, some students abuse the drug because simply for the high it gives
Like Jason, more and more children are being diagnosed with ADHD or its less hyperactive cousin, attention deficit disorder (ADD). And, correspondingly, during the past decade the production of stimulants used to treat ADD has risen dramatically, (see Graph 1.). However, an increasing number of parents, doctors, and public health officials are becoming alarmed about the jump in the use of Ritalin and amphetamines to treat ADD. In the last year, at least three prestigious medical journals published articles examining whether the condition is being overdiagnosed and American children are being drugged unnecessarily, (N...
Bayon's first body paragraph illustrates America's economic vulnerability in order to prove the topic of America's dangerous overdependence on oil. We consume more than our domestic oil supply due to being so oil dependent, and as a result the author indicates Washington D.C. is practically forced to do business with hostile countries for oil. This creates economic vulnerability of the United States to oil price spikes and inflation possibilities. In 2008, "The United States imported 4 million barrels of oil daily, or 1.5 billion barrels yearly from "dangerous or unstable" countries at a cost of about $150 billion per year. (www.americanprogress.org)." These oil prices of $150 billion dollars per year can be decreased if hydrogen fuel cells were in greater use. As a result of the laws of supply and demand, the United States will have no power over the increasing prices o...
U.S. energy dependence is higher today than it was during the oil shock of the 1970's, and oil imports are projected to increase. Passenger vehicles alone consume 6 million barrels of oil every single day. If just 20 percent of cars used full cells, we could cut oil imports by 1.5 million barrels every day. 10,000 fuel cell vehicles running on non-petroleum fuel would reduce oil consumption by 6.98 million gallons a year.
Hip implants have been utilized even longer than metal-on-plastic implants. Metal-on-Metal bearings (cobalt chromium alloy, titanium alloy or from time to time stainless steel) were in use from as distant back as 1955 nevertheless they were not agreed for use in the U.S. by the FDA till 1999. They proposal the possible for considerably decreased wear, alongside less inflammation and less bone loss. A little mechanism recalls have held negative attention to Metal-on-Metal. Metal-on-metal constituents permit the biggest heads across the whole scope of implant sizes. Colossal ball heads furnish increased scope of gesture and larger stability, that can considerably cut the chance of hip dislocation, a critical factor in the long word accomplishment of an implant.
Enzymes are an important part of all metabolic reactions in the body. They are catalytic proteins, able to increase the rate of a reaction, without being consumed in the process of doing so (Campbell 96). This allows the enzyme to be used again in another reaction. Enzymes speed up reactions by lowering the activation energy, the energy needed to break the chemical bonds between reactants allowing them to combine with other substances and form products (Campbell 100). In this experiment the enzyme used was acid phosphates (ACP), and the substrate was p-nitrophenyl phosphate.
Abuse of drugs has not however been limited to the professional athletic world. According to research conducted by Dr. Philip Veliz, Dr. Carol Boyd, and Dr. Sean Esteban McCabe, there has been a connection discovered between the abuse of ADHD medication and male athletes in high school. Beyond sports, there has been a recent development that is becoming a cause for concern in high school and college classrooms. More and more students have admitted to abusing the drug Adderall. They have turned to it in the hope of improving focus, helping their memory during study sessions, and increase performance on exams. This is an issue that is demanding a solution.
U.S. Heath News reported (2013) that 6.4 million children ages 4 to 17 have been diagnosed with Attention Deficit Hyperactivity Disorder. Since 2007, the utilization of stimulant medication to treat ADHD has jumped 11% nationally as a whole. It was also reported that the U.S. spends more on prescription drugs to treat Attention Deficit Hyperactivity Disorder than it does for all but six other medical conditions (U.S. News Health, 2013). The number of ADHD diagnosed teens prescribed stimulants, such as Ritalin and Adderall, will be increasing over time as the new guidelines set by the American Academy of Pediatrics now recognizes physicians prescribing ADHD stimulant medications to childre...
Adderall is a useful drug when used correctly at the right moment. There are serious cases when people, mostly college students, don’t need the drug, but use it to stay focused on studying and homework. They’re typically cheating on tests when the drug is being used without a prescription from a doctor. They soon become dependent of the drug and have issues in the near future. Adderall can be a helpful drug, but if used incorrectly can lead to a bad mental state, but if you do need it, it could be the key factor in making your life successful.
Alumina and zirconia ceramics have been widely used in orthopaedic hip replacements for the past 30 years. The advantage of using these was lower wear rates than those observed using polymers and metals. Because of the ionic bonds and chemical stability of ceramics, they are relatively biocompatible and therefore more preferable to use than metals and polymers. Alumina is most commonly used as a femoral head component instead of a metal in a hip prosthesis because this would reduce the polyethylene wear that is generated. Alumina is a desirable biomaterial to use in hard tissue implants because of characteristics like excellent wear resistance, high hardness, bio inert, low abrasion rate and good frictional behaviour. Furthermore, it has excellent surface finish as well as high fatigue streng...
College can be a challenge with endless papers, tests, and other tasks. A pill that allows extreme focus helps accomplish necessary tasks. Adderall is a prescription medication given to patients with Attention Deficit Hyperactivity Disorder (Jaffe). However, this drug has become known as a “smart drug” around college campuses (“Daily News & Analysis”). About 6.4 percent of college students have taken Adderall without a prescription (Carver). At more competitive schools, about twenty-five percent of students have taken Adderall (Pantovich). Students take the drug with hope to improve a grade. However, in the long run, the student only hurts himself or herself.
... we may see a serious act in the near future to start the process of drilling. With a solid combination and profitability factor the U.S. could prevent the rising gasoline prices. We need to however, continue our search for other alternatives do to our limited resource of oil. For this reason, I am in favor of opening up the Arctic National Wildlife Refuge to oil drilling and also the exploration of alternative fuel sources, as well as ways to conserve fuel. This combination should provide the United States with an energy policy that is both financially stable and environmentally sound.
Prescription stimulants are sensationalized in the media as the ticket to a 4.0 GPA. “In one study, the primary reasons students provided for illicitly using prescription stimulants were to help concentrate, increase alertness, and get high. Of note, many students also wrote in ‘to study’ as a motive that was not provided as a fixed item in the survey...” (Hall, 2005). Students hear their friends with ADHD talk about the benefits they receive from taking their prescribed stimulants, then decide to use prescription stimulants that are not theirs, in hopes to achieve the same effects.
Enzymes are protein molecules that are made by organisms to catalyze reactions. Typically, enzymes speeds up the rate of the reaction within cells. Enzymes are primarily important to living organisms because it helps with metabolism and the digestive system. For example, enzymes can break larger molecules into smaller molecules to help the body absorb the smaller pieces faster. In addition, some enzyme molecules bind molecules together. However, the initial purpose of the enzyme is to speed up reactions for a certain reason because they are “highly selective catalysts” (Castro J. 2014). In other words, an enzyme is a catalyst, which is a substance that increases the rate of a reaction without undergoing changes. Moreover, enzymes work with
Wind is a form of solar energy. The term wind energy describes the process by which the wind is used to generate electricity or mechanical power. Wind turbines convert mechanical energy from the wind into electrical power. Wind turbines usually have three main parts. There are blades that connect to a central hub, a box behind the blades that contains the generator, and a long stem that connects to the ground. The way how it works is that the wind turns the blades, which spins a shaft that connects to a generator making electricity. After the electricity is produced it is sent through transmission lines to a substation that is sent to business and homes. For the sake of our planet, we must promote a renewable energy economy. Wind power can be a foundation of that sustainable energy future because it provides jobs in states that are building wind turbines, is a renewable energy source, and does not damage our environment. The environment will not be damaged by the pollution, the natural resources will not be used up, and there won’t be generating of hazardous wastes. Welcoming wind energy today will lay the foundation for a healthy tomorrow that will affect everyone in the United States. There are obstacles and challenges that will make it more difficult, but the environmental impact is well worth it to invest more money into wind energy.
