others. Mysticism aside‚ the study of blood clotting and the development of laboratory tests for blood clotting abnormalities are historically inseparable. The workhorse tests of the modern coagulation laboratory‚ the prothrombin time (PT) and the activated partial thromboplastin time (aPTT)‚ are the basis for the published extrinsic and intrinsic coagulation pathways‚ even though it is now known that these pathways do not accurately reflect the function of blood clotting in a living organism.

Introduction: Dependence of Methane Production on Ambient Temperature in Bovine Waste The purpose of this experiment was to determine the effect of temperature in bovine waste on the amount of methane evolved. The hypothesis stated that the bovine waste heated to 48.9oC would produce the most methane. The manipulated variable in the experiment was the temperature of bovine waste. The responding variable was the amount of methane evolved from the waste. The experiment can be applied to real world

Chapter 2 REVIEW OF RELATED LITERATURE AND STUDIES Related Literature Spider silk (Parasteatoda tepidarium) commonly known as agiw in Filipino‚is a material spun by varieties of spiders.Spider silk has a unique combination of mechanical strength and elasticity that makes it one of the toughest materials we know.(Arizona State University‚2013). Furthermore‚silk consists of very repetitive blocks of mainly glycine and alanine.These are the simplest and smallest amino acids allowing strands to be packed

The Children of Destiny The streets of the dingy‚ smog-filled city city were quiet‚ so silent‚ one could hear a pindrop from several feet away. Soot clung to the city air‚ and seemingally to the buildings themselves‚ which‚ along with the darkness of the night‚ left the city in pitch darkness‚ with the glow of the streetlamps failing to penetrate the thick‚ smoggy cloak that had been cast over the capital city of Hila. No one was about; only the occasional army patrol or bandit broke the silence

confidence interval for μ (true mean processing time) is given by 3.8 ± 1.645 × 1.2/ √40 = 3.8 ± 0.31 = (3.49‚ 4.11) minutes. Q.3 The amount of PCBs (polychlorinated biphenyls) was measured in 40 samples of soil that were treated with contaminated sludge. The following summary statistics were obtained. x = 3.56‚ s = .5ppm Obtain a 95% confidence interval for the population mean μ‚ amount of PCBs in the soil. Solution: For large n‚ a 95% confidence interval for μ is given by X ±z0.025 ×S/√n Using

malaria‚ but instead he accidently started a new movement in the fashion industry. In 1856 Perkin was attempting to create artificial quintine‚ an anti-malaria drug derived from tree bark. He failed‚ however his failure resulted in a thick purple sludge. The color caught his eye‚ it was a very unique shade of purple. He was able to isolate the compound producing the color which he named mauve. Perkin had created the first ever synthetic dye. Perkin’s dye was quite vibrant and didn;t fade or wash

Nuclear Power‚ Friend or Foe? Its seems that the world is in a constant search of a cleaner‚ cheaper and safer power plants. Nuclear energy has emerged as a new alternative for power. The first nuclear power plant was built in the 1950’s and is now used all over the world. France receives 80% of their electrical energy from nuclear power plants‚ however; here in the U.S. we only receive 19% of our electrical energy from nuclear power plants. Whereas nuclear power comes with cons‚ such as safety
