.... that is black and sticky known on the streets as “black tar heroin”. Opiates are drugs that are derived from a naturally occurring substance found in the poppy plant. Although the purity of the heroin that reaches the streets is becoming greater, most street heroin is cut or diluted. Usually this is done with another drug, or a substance such as sugar, starch, powdered milk, or quinine. Street heroin can also be cut with strychnine or other poisons. The reason heroin is one of the most deadly drugs is because there are varying rates at which the drug is diluted. Therefore a user never knows exactly how pure the drug is, hence, they do not know how much of the drug t ....

.... a roll of paper towels, and a spraycan. By dividing the circumference of the circle by the diameter I was able to calculate the experimental ratio, and I knew that the accepted ratio was pi. Then I put both ratios in the chart. By subtracting the accepted ratio from the experimental you find the error. Error is the deviation of the experimental ratio from the accepted ratio. After I had the error I could go on to find the percentage error. The equation I used was, error divided by the accepted ratio times 100. For example, if I took the error of the experimental ratio for the paper towels, which was 0.12. I took that and divided it by the accepted ratio giving me .03821651. ....

.... floors of buildings, automobiles and anything else that may have fallen victim to the hurricane's epic floodwaters. Workers hack and chip at the mud with shovels and pickaxes, and an endless procession of shopowners scurry between their gutted businesses and the river in a desperate attempt to wash and salvage their goods. A muddy valley runs past the Central Prison, where some of the incarcerated swam to freedom as Mitch's floodwaters rose and propelled them over the walls. Hundreds of homes, streets, and businesses were washed away, and those that remained standing found themselves anchored beneath several feet of mud and debris. In some places, the stenc ....

.... to urinate and perform sexually. SYMPTOMS OF PROSTATE CANCER Prostate cancer occurs when some of the cells that make up the prostate gland escape from the normal controls on their growth and start to divide, grow and spread in an uncontolled manner. At first the growth of the cancer occurs very slowly and is usually limited within the prostate gland. Later on in the course of the illness, the prostate gland cells can spread around the body, particulary to the bones where they can paues pain and disability. Estimates show that the cancer may have been growing in some men for up to 10 yearsbefore it causes symptoms and is diagnosed. Some men dev ....

.... The result was pulses of red laser light. Once they made the device they had to name it. They had think of some word or words to described it. They came up with Light Amplification by Stimulated Emission of Radiation. Using the first letter of each main word they named it laser. The laser had everyone excited. The laser was put through many tests and experiments to see what it could do to help modern civilization. At first there weren't many uses for the laser. Then in the 1970's it became very important. It was finally being used in everyday life. As years went on the uses grew in number. Today lasers were being used in a variety of ways. This includes entertai ....

.... They have several single-syllable call notes which include tchick, an aggressive social note; a tick and a tkhirrr, which are alarm notes. There is also a location call, known as a "whinny", made up of a dozen or more tchicks all strung together. Scientific Names The downy woodpecker's scientific name is Picoides pubescens. There are also six particular downies with six particular scientific names all from different regions of the United States and southern Canada which I have listed below: southern downy / Dryobates pubescens Gairdner's woodpecker / Gairdneri pubescens Batchelder's woodpecker / Leucurus pubescens northern downy / Medianus pubescens Nelson ....

.... it loses quality. Digital audio uses a binary code representation of the continuous stream of data. Once in this form, it can be modified in any way without any degradation of the original sound. One can make copies of copies with digital audio, and the hundredth will be exactly like the first. The great advantage of digital audio with respect to radio is the possibility of listener interactivity. Currently, any interactivity is limited by the inability of the individual talk to the other end of a radio transmission chain. When one switches stations on our radio, there is no interaction, we are simply selecting from a series of predefined options, just like changing cha ....

.... between the African, Eurasian and North American Plates. Africa and North America were joined into one super continent. The collision of these land masses over 1 billion years ago metamorphosed the original rock producing the Pedler gneiss and Old Rag granite which can be observed in the Shenandoah National Park. In late Precambrian time this super continent began to rift apart under the tensional forces producing the Catoctin rift basalts that can be observed in the Shenandoah. As they rifted apart, they created a growing ocean called the proto-Atlantic or Iapetus after the father of Atlas, for whom the Atlantic Ocean is named. Towards the end of the Precambrian, the ....
