    Add Attention Deficit Disorder For centuries children have been grounded, beaten, or even killed for ignoring the rules or not listening to what they're told. In the past it was thought these "bad" kids were the products of bad parenting, bad environment, or simply being stubborn, however it is now known that many of these children may have had Attention Deficit Disorder, or A. D. D., and could've been helped. A. D. D. is a syndrome that affects millions of children and adults in the United States and is a very frustrating and confusing syndrome that often goes undiagnosed. While there is no clear-cut definition of A. D. D., it's known that it's a genetic disorder that affects males more oft ...

  • Aluminum - 1,420 words
    Aluminum Aluminum is one of a number of soft metals that scientists call poor metals. It can be shaped and twisted into any form. It can be rolled into thick plates for armored tanks or into thin foil for chewing gum wrappers. It may be drawn into a wire or made into cans. Aluminum is a generally popular metal because it does not rust and it resists wear from weather and chemicals. (Bowman, 391) Aluminum is an element. Its atomic number is thirteen and its atomic weight is usually twenty-seven. Pure aluminum melts at 660.2C and boils at 2500C. Its density is 2.7 grams per cube centimeter. Aluminum is never found uncombined in nature. (Bowman, 391) Aluminum is a very useful metal that is ligh ...

  • Bipolar Disorder - 729 words
    Bipolar Disorder Bipolar disorder is perhaps one of the most tragic mood disorders, because it virtually taunts with the affected persons mind. Bipolar disorder (also known as manic-depressive disorder) is a mental condition in which the person alternates between feelings of mania and depression (Kalat, 614). These feelings are extreme opposites, and thus create tremendous mental and physical stress on the person affected. This unfortunate disorder affects one to two percent of the adult population. Before bipolar disorder can be fully understood, the two main mood stages must first be identified. During an endless bout with bipolar disorder, a person experiences many stages of mania and dep ...

  • Bipolar Disorder 2 - 1,276 words
    Bipolar Disorder 2 Bipolar affective disorder has been a mystery since the 16th century. History has shown that this disorder can appear in almost anyone. Even the great painter Vincent Van Gogh is believed to have had bipolar disorder. It is clear that in our society many people live with bipolar disorder; however, despite the amount of people suffering from it, we are still waiting for explanations for the causes and cure. The one fact of which we are aware is that bipolar disorder severely undermines its' victims ability to obtain and maintain social and occupational success. Because bipolar disorder has such debilitating symptoms, it is important that we keep looking for explanations of ...

Bipolar people abuse drugs, such as alcohol, cocaine, and sleeping medications. They also often deny that they are manic because they think that everything is okay with them because they feel so good about themselves (Bipolar Disorder 2). The other side of being Bipolar is the lows that a person has to go through, the depressed part of the disorder.

    ... re senile plaques (SP) and Neurofibrillary tangles (NFT). There are two types of SP, neuritic and diffuse, both plaques share antigenic determinants with the Beta amyloid 4 protein. Neuritic plaques can be distinguished by their abnormally thickened neurites ( i.e., axons or dendrites) arranged around a central core of amyloid (Mirra & Gearing, 1994). By contrast the diffuse plaques lack the thickened neurites and the amyloid core seen in the neuritic plaques (Mirra & Gearing, 1994). Plaques of both types are found in varying degrees in the neocortex, entorhinal cortex, hippocampus, and in the amygdala. SP also occur in the brains of healthy people. It is only when they exceed a certain ...

  • Depression And Relationships - 1,147 words
    Depression And Relationships A primary concern for Psychology research is depression. Depression affects a great deal of our population and many aspects of an individual's mental health and well-being. In my research of books, articles, and Internet pages on depression, I chose to base my paper mainly on a 1994 article of a study of depression, entitled Depression, Working Models of Others, and Relationship Functioning, by Katherine B. Carnelley, Paula R. Pietromonaco, and Kenneth Jaffe. This study focuses on the idea that the type of care received in childhood, positive or negative, has a great effect on relationship functioning later in adulthood. But there are two links between child-rear ...

  • Depression Is A - 607 words
    Depression is a psychiatric disorder characterized by feelings of worthlessness, guilt, sadness, helplessness, and hopelessness. It is different then normal sadness or grief from the loss of a loved one because it is persistent and severe. Clinical depression has many related symptoms trouble sleeping, eating disorders, withdrawal and inactivity, self-punishment, and loss of pleasure. People that are depressed do not like to do things they may usually like to. Surveys that have been taken that show approximately 20 in 100 people suffer from depression at any one time. About one if four Americans will suffer from a depression over the course of their lifetime. Depression strikes men and women ...

  • Dothiepin Vs Fluoxetine Mechanism Of Action And Pharmacodynamics - 1,290 words
    Dothiepin Vs. Fluoxetine (Mechanism Of Action And Pharmacodynamics) Comparison Between Mechanism of Action and Pharmacodynamics of Dothiepin and Fluoxetine Description of medicines Mechanism of action and pharmacodynamics Dothiepin Dothiepin is a tricyclic antidepressant. It acts by promoting the effectiveness of several amines (dopamine, norepinephrine, and 5-hydroxytryptamine, which is also known as 5HT and serotonin). It functions by inhibiting their reuptake at the terminals of nerve cells, thus leading to their prolonged presence at the synaptic cleft and an increased effect on the neuron.(1) The reuptake pumps for the above amines are responsible for reducing the concentration of these ...

  • Fusion - 1,323 words
    ... eating, and the onset of nuclear fusion. The situation in star formation differs in one respect: after gravitational collapse ceases and star begins to expand again due to heat from exoergic nuclear fusion reactions, the expansion is arrested by the gravity force associated with the enormous mass of the star. In a star a state of equilibrium in both size and temperature is achieved. In ICF, by contrast, complete disassembly of fuel occurs. The fusion reaction least difficult to achieve combines a deuteron (the nucleus of the deuterium atom) with a triton (the nucleus of a tritium atom). Both nuclei are isotopes of the hydrogen nucleus and contain a single unit of positive electric charge ...

  • Fusion Energy - 860 words
    Fusion Energy A fusion reaction is one in which two atomic nuclei merge to form a heavier nucleus. this is the process that happens in in the stars. In average stars, like the sun, the process of fusion is converting hydrogen nuclei (or protons) into helium nuclei. There is an enormous amount of kinetic energy and gamma rays released in this process that heat the star's interior, and this realease is what maintains it at the extreamly high temperatures (greater than 10 million K) required to continue the fusion. This process has been making the stars go for billions of years has clear potential as a power source on earth. Once we have started the reaction, Fusion requires no energy and reale ...

  • Hydrogen - 638 words
    HYDROGEN Hydrogen, symbol H, is reactive, colorless, odorless, and tasteless gaseous element. The atomic number of hydrogen is 1. The element is usually classed in group 1 of the periodic table. Hydrogen was confused with other gases until the a British chemist demonstrated in 1766 that it was evolved by the action of sulfuric acid on metals and also showed at a later date that it was an independent substance that combined with oxygen to form water. The British chemist Joseph Priestley named the gas "inflammable air" in 1781, and the French chemist Antoine Laurent Lavoisier renamed it hydrogen. Like most gaseous elements, hydrogen is diatomic, but it becomes and turns into free atoms at high ...

  • Hydrogen Bomb - 821 words
    Hydrogen Bomb The Hydrogen Bomb The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release huge amounts of energy. The hydrogen bomb is about a thousand time more powerful than the atomic bomb, which produces a nuclear fission explosion almost a million times more powerful than that of a comparably sized bomb using conventional high explosives such as TNT. The atomic bomb was an essential first step towards the development of the hydrogen bomb, before the atomic bomb w2as developed by the United States during World War 2, there was no way to produce the extreme amounts of heat needed to initiate the ...

    Marijuana Should Be Legal Seven Leaves Aren't Bad: Marijuana Should Be Legal Thesis: Should marijuana be legalized and can it be used in positive ways? In 1937, the Marijuana Tax Stamp Act prohibited the use, sale, and cultivation of hemp/marijuana in the United States. Marijuana is a drug that is highly used through out the world. It comes from the cannabis plant. THC which stands for delta-9-tetrahydrocannabinol is the major psychoactive ingredient. Over sixty five million Americans today use marijuana. Today it is a lot stronger than how it used to be in the 1970's because of careful cultivation. It can be smoked threw a pipe, joint, or it can even be used as an ingredient in food. Althou ...

  • Nuclear Bombs - 1,087 words
    Nuclear Bombs THE FIRST DESIGN of a nuclear weapon in the United States was a gun-barrel assembly, in which two sub-critical masses of very highly enriched uranium (HEU), were brought together by normal artillery propellant in a short gun barrel into a single over-critical configuration. (Criticality defines the minimum amount of a fissionable material in a particular configuration and density capable of a self-sustaining chain reaction). The second type of fission weapon is the implosion assembly, in which a high explosive (with a much faster detonation speed than the propellant used in a gun-type weapon) compresses fissile material so that it reaches a super-critical mass. Less fissile mat ...

  • Nuclear Fusion - 508 words
    Nuclear Fusion Nuclear Fusion is the energy-producing process which takes place continuously in the sun and stars. In the core of the sun at temperatures of 10-15 million degrees Celsius, Hydrogen is converted to Helium providing enough energy for us to sustain life on earth. For energy production on earth, different fusion reactions are involved. The most suitable reaction occurs between the nuclei of the two light forms (isotopes) of Hydrogen - Deuterium and Tritium; eventually reactions involving just Deuterium or Deuterium and Helium may be used. A brief breakdown of the fuels used are as follows, Deuterium is a very abundant isotope of hydrogen and can be extracted from all forms of wat ...

  • Nucleosynthesis - 1,314 words
    Nucleosynthesis The big bang which created the universe, only created the elements Hydrogen (H) and Helium (He) and possibly a very small amount of Lithium (Li). However, a glance at the periodic table of the elements shows that today (some 15 billion years after the big bang) there are at least 108 known elements. Every atom of every element heavier than Li has been produced since the big bang! The factories which make these elements are stars. Nucleosynthesis or the synthesis of nuclei, is the process by which stars (which start out consisting mostly of H and He) produce all other elements. The key is nuclear fusion, in which small nuclei are joined together to form a larger nucleus. (This ...
