.... caused by injuries, strokes, exposure to toxic substances, ethnicity, and bacterial infe- ction. The plaques, formed in the brain areas affetcts the memory of the patient. They are loated outside and around neurons as dense de- posits of an amyloid protein. According to researchers, amloid is a cause of Alzheimer. Even thougt there is no cure for AD, it exist a number of treat- Ment. If you suspect a patient of AD, ask him an attention question, like, “why people who lives in glasses houses shouldnt throw rocks.” If he fails to answer, he might have Alzheimer disease and should be refered to a treatment.. There is 3 stages in AD. Mild: the patient might .....

.... the disorder. The disorder is defined as a person having inappropriate degrees of inattention, impulsiveness and hyperactivity. The symptoms that have been displays with in the degree of inattention are: „h The difficulty of paying attention in tasks or a certain amount of time. „h Trouble with following instructions. „h Often losing things for needed tasks. Impulsiveness of the disorder may include the following: „h Acting before thinking - this may lead to failing academically or friction in social relationships. „h Difficulty in waiting turns, interrupting or intruding on conversations/games. Examples of hyperactivity will be seen through the child oft .....

.... at the same time the voltage decreases. As a result the rate at which the capacitor is discharged, which is the current, is decreased. The outcome of this is that the capacitor will be completely discharged meaning that both the current and voltage will equal zero. At this time all the energy stored in the circuit will have been transferred to thermal energy at the resistor. A heater uses electrical power. The power dissipated in a resistor is in return proportional to the resistance and the square of the current that passes through it. As the energy is changed from electrical to thermal the resistor gets hot. In long distance transmission, current is r .....

.... wars were fought over it (Korea and Vietnam) and a nuclear war was almost waged (Cuban Missile Crisis). Now with the breakup of the Soviet Union into a loose Commonwealth no one is exactly sure who has all the weapons. Certain nations inherited them, Belarus, Kazakhstan, Ukraine, and Russia, while others tried stealing them, Iran, Libya, and North Korea. And since the breakup certain people have been caught stealing the materials needed to make a bomb. These terrorists have never been caught in the United States but numerous times in Europe.(www.pbs.org) As a matter of fact, the Russians say someone stole a bomb simulator, which will explode and make mushroom c .....

.... only. They store their toxin in their meat or skin. If someone or something eats the animal, the predator may get sick or even die. Most marine creature fall into two categories invertebrates (animals without backbones) and vertebrates (animals with backbones.) These animals are further broken down into phylums and classes. ECHINODERMS Echinoderms are marine invertebrate animals of the phylum Echinodrmata, having external skeletons of calcareous plates just under the skin, no head, and a water vascular-system with tube feet. Echinoderms are radially symmetrical, lack specialized ecretory organs, and reproduce sexually. Echinoderms have the ability to rege .....

.... detect pathogens. It relies upon amplification technology utilizingthe heat stable DNA polymerase from a thermophilic organism." (from http://www.genes.com/pcr/pcrinfo.html) Dr. K.Mullis recently received the Nobel prize for inventing the technique. This is how they go about doing this: They first get their small DNA sample. Then they mix all the chemicals (this includes the primer, etc). Then they have to run it through the PCR machine. Here is a (rather detailed) description of the process: "The cycling protocol consisted of 25-30 cycles of three- temperatures: strand denaturation at 95degC, primer annealing at 55degC, and primer extension at 72deg C, t .....

.... advantages of different types of clones, such as they are useful for research. We will also be discussing the disadvantages and different techniques that result from the cloning of different organisms. First lets start with the history of cloning. The modern era of laboratory cloning began in 1958 when F.C. Steward cloned carrot plants from mature single cells placed in a nutrient culture containing hormones. The first cloning of animal cells took place in 1964. John B. Gurdon took the nuclei from tadpoles and injected them into unfertilized eggs. The nuclei containing the original parents’ genetic information had been destroyed with ultraviolet light. When t .....

.... patterns that are a result of atomic planar spacing. Before getting into the specifics of the Debye-Scherrer camera it will be advantageous to beginning with the fundamental concept of simple harmonic motion as it relates to light waves. Simple harmonic motion is the condition in which a particle that is moving along the x-axis has a displacement function given by the following relation x = Acos(wt + f) where x is the position along the x axis A is the amplitude or in other words the maximum possible displacement w is the angular frequency and f is the phase constant or phase angle and has units of radians per second. The phase constant determines t .....
