.... living species of hammerheads. The following four are the main categories: 1. Scalloped hammerhead (Sphyrna lewini)-Pectoral fins are tipped with black this grey shark. The maximum length is about 12 feet. 2. Bonnethead (Spyrna tiburo)-With a head shaped like a shovel the bonnethead rarely grows more than four feet long. This shark is commonly seen inshore. 3. Smooth hammerhead (Sphyrna zygaena)-Bronze with dusky fin tips, it can grow to thirteen feet. 4. Great hammerhead (Sphyrna mokarran)-Attaining a length of a possible 18 feet, this is the largest and most dangerous of all the hammerheads. One of the most interesting things about the hammerheads is the unique ....

.... which obeys Ohm's Law and has been designed to have a specific value for its resistance. As an extension of the Ohm's Law, two more relationship can be drawn for electric circuits containing resistors connected in series or/and parallel. For resistors connected in series, the sum of their resistance is, RTOTAL=R1+R2+ ..... +Rn . And for resistors connected in parallel, 1/RTOTAL==1/R1+1/R2+ ..... +1/Rn . Complex dc circuit involving a combination of parallel and series resistors can be analyzed to find the current and voltage at each point of the circuit using 2 basic rules formulated by Kirchhoff. 1) The algebraic sum of current at any branch point in a circuit is z ....

.... At this distinctive location, the country is affected by the alternate seasonal expansion and contraction of the polar continental highs and tropical maritime air masses, along with the seasonal shifts of the overhead sun. These changes in the pressure systems over Asia generate the unique Asian monsoon circulation which prevails over China throughout the year. Surface Pressure Field and Winds: For any fluid to initiate movements, pressure gradient must exists. Therefore, for a close understanding of the circulation system that operates over China, we should start from discussing the seasonal pressure distribution at sea-level over the Asia-Pacific region, which is the dri ....

.... "resulting from acute intoxication following inhalation of butane gas." Hemiparesis is when half of a person's body is paralyzed. Through reactions alkanes can be transformed into chloroform. This has been shown to accumulate in lungs of swimmers after they swim for extended periods of time. As mentioned above chloroform can be produced which can be used for anesthesia. Also dichloromethane, or paint stripper and 1,2-dichloroethane which is a dry cleaning fluid. Here is a sample reaction where a halogen replaces a hydrogen. CH4(g) + C12(g) ----> CH3Cl(g) + HCl(g) There are many uses for alkanes, for instance: Propane is used in gas grills, butane is used in c ....

.... in muscle growth. Steroids basically speed up muscle repair and slow down the body’s natural tendency to break down muscle. Popular media has insinuated to the public about horror stories and the dangers. If they are so dangerous then why do doctors prescribe them? Why do pharmacies all over the planet still make them and sell them? To have an opinion on whether steroids are safe are not, it would help to know how they work and what responsibilities are needed when choosing to take them. are a synthetic for of the naturally occurring hormone, testosterone. are used to promote accelerated muscle hypertrophy in both males and females. Hypertrophy describes the ....

.... and the extreme in which asthma symptoms occur vary from one person to another. Most attacks occur at night, beginning with coughing or wheezing and shortness of breath, but in some people a dry cough may be the only symptom. This may be partially due to the fact that you stay in your room sleeping for eight hours at a time. Dust mites collect in your bedding, curtains, pillows and rugs. To avoid this, you should have your mattress and pillows sealed in a plastic covering, no curtains and you should have hard wood floors in your bedroom, instead of rugs or carpets. " Office Visits: From 1975 to 1993-1995, the estimated annual number of office visits for asthma more than ....

.... use of animals for research and testing is only one of many investigative techniques available. We believe that although animal experiments are sometimes intellectually seductive, they are poorly suited to addressing the urgent health problems of our era, such as heart disease, cancer, stroke, AIDS and birth defects." He goes on further to say that animal experiments can not only mislead researchers but even contribute to illnesses or deaths by failing to predict any toxic effect on drugs. The majority of animals in laboratories are used for genetic manipulation, surgical intervention or injection of foreign substances. Researchers produce solutions from these animal ....

.... cell bearing the recombinant vector, in a short time a large amount of DNA of interest is produced. This can be purified from contaminating bacterial DNA easily and the resulting product is said to have been "cloned". So far, scientists have used genetic engineering to produce, for example: - improve vaccines against animal diseases such as footrot and pig scours; - pure human products such as insulin, and human growth hormone in commercial quantities; - existing antibiotics by more economical methods; - new kinds of antibiotics not otherwise available; - plants with resistance to some pesticides, insects and diseases; - plants with improved nutritional qualities to enhan ....
