.... Since these children do not meet the expectations of society and their learning environment they are usually met with anger, punishment, and rejection. In turn these children develop a low-self esteem and low levels of motivation (Morgan, 1997). The etiology of ADHD is still a mystery to researchers. Within the field there are many correlates to biological (genetic) and social causes. The present paper seeks to explore current research through investigating the social and bio-genetic influence of ADHD on child intelligence. Testing and treatments of those with ADHD will also be discussed. In accordance with Dulcan et al. (1997) ADD, ADD-H, ADHD, althou .....

.... discussing the individual fossil specimens to to preface with what exactly is meant by the terms “modern” and “archaic” in reference to skull morphology. “Modern” features in skull morphology as the word is used here include thin cranial walls, small supraorbital ridges, small teeth, small eye sockets, broad, flat foreheads, large cranial volume (above 1200 cc.), low prognathism in the area of the lower face, and a high, vaulted shape in the area of the cranium. “Archaic” features in skull morphology include thick cranial walls, heavy supraorbital ridges, large teeth, large eye sockets, sloping foreheads, low c .....

.... colloidal state in which the molecules of the dispersed phase form a three- dimensional structure in the continuous phase to produce a semisolid material such as a jelly. For example, a warm, dilute(2 percent) solution of gelatin(a protein mixture) forms, on cooling, a stiff gel in which the molecules of the continuous phase are trapped in the holes of a "brush-heap" like structure of the gelatin. Administered orally. Microemulsion: Microemulsions are thermodynamically stable, optically transparent, isotropic mixtures of a biphasic oil-water system stabilized with surfactants. The diameter of droplets in a microemulsion may be in the range of 10 .....

.... 9 yards. The History of the Golf Ball: The first ever golf ball was called the Feathery and introduced in the 1400's it was a stitched leather pouch soaked and then stuffed with goose feathers. Upon drying, the feathers expanded and the leather contracted, forming an extremely hard mass. This was hammered round and painted white. The feathery sometimes flew over 300 yards and was durable - until it got wet. Then it would split open. The Gutta percha was introduced in 1850 and was made of a rubberlike sap from the Malaysian sapdilla tree. The material was heated to soften it and then hand-formed into a solid, one piece ball.Gutta percha was black, so the .....

.... pin 6 and 2 of the 555 IC. If the voltage is LOW, the bottom LED lights. If the input voltage is HIGH, the top LED lights. When the input probe is disconnected, both LEDs light. Note that pin 3 of the 555 IC always goes to the opposite logic level of the input. Therefore, if the input is HIGH, the output of the 555 IC, which is pin 3, goes LOW. This in turn activates and lights the top LED (the HIGH indicator). Logic probes derive their operating power from the PCB under test. Care should be taken in attaching the clips to safe voltages; you may want to first use a Volt Meter (Digital Multi Meter) to verify the hook up points have good voltages. The four diodes .....

.... acidic. It is caused by today's industry. When products are manufactured many chemicals are used to create it. However because of the difficulty and cost of properly disposing of these products they are often emitted into the atmosphere with little or no treatment. The term was first considered to be important about 20 years ago when scientists in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a .....

.... The nucleus is pretty solid and stable, composed mostly of ice and gas with a small amount of dust and other solids. The surface of the nucleus is best described as a black crust. Comet nuclei can range from 1 kilometer to about 50 kilometers across. The black crust on the surface of the nuclei helps the comet to absorb heat, which causes some of the ices under the crust to turn to a gas. Pressure builds up underneath the crust and causes the surface to bubble up in some places. Eventually, the weak spots of the crust break open from the pressure, and the gas shoots outward; this is referred to by astronomers as a jet. Dust that had been mixed in with the gas .....

.... work where they spend the day in a well lit workspace. Yet, they never give a second thought to the source of the energy that their daily lives depends on. Over eighty-five percent of the energy that powers the planet is derived from the burning of fossil fuels (Information 16). Fossil fuels contain impurities and these “impurities such as sulfur also burn and produce potentially dangerous oxides” which are released into the air (Burning www 1). Releasing these oxides into the air has many consequences including smog, which is the most noticeable of these problems. The hazy smog that hangs over us in the summer is actually ground level ozone; .....
