series of tests. From factors of bone thickness, burial depth, and the presence of water and climate. The results of the tests are that DNA is calculated that DNA of 174 base pairs could not survive long but small thirty base pairs at negative five Celsius predicts a half-life of 158,000 years. The most DNA can survive in extremely small base pairs was calculated in extreme deposition of deep freeze in Greenlandic ice cores is one-million years. The research is reliable. The conclusions come…
degrees Celsius for 12-16 hours (1). Volatile compounds were extracted from the ACS, and the samples underwent Gas Chromatography-Mass Spectroscopy (GC-MS). Then, Almirall and Fulton administered controlled pyrolysis burning in order to provide a classification standard of what pyrolysis products can be expected at a crime scene under certain conditions. This was achieved by placing a small piece of the sample into a pyrolyzer without air and pyrolyzed for 25 seconds at 800 degrees Celsius.…
The Continental Divide has a tremendous impact on weather in North America and even as far away as Norway. Situated in the western half of North America running north and south, the Continental Divide creates a wall that moisture rich prevailing winds from the west continually bunch up against. As the pressure of packed moist air continues to build, the prevailing winds carry the energy up the western side of the divide allowing the system to build until it is released to the east to dump its…
National Labor Committee in 2010. There are nearly a thousand “work study” students, most of which is below age 15. They would have to world 15 hours a day, seven days a week, paying 65 cents per hour. The working conditions are on average 32 degree Celsius with no air-conditioning, talking and music were not allowed, o shower but a bucket of water with sponges and in each dorm there lived 14 workers. Security guards were often reported for sexual harassment. KYE is an electronic supplier for…
Imagine living somewhere where the temperature averages between 25 to 30 degrees Celsius year round, there are beaches and palm trees around every corner and there’s green grass and bright colourful flowers everywhere you look. Today I’m going to be talking to you about the Hawaiian culture. The Hawaiian culture has a wide range of interesting topics but the ones that I have chosen to enlighten you on today are the different extreme sports that the people in the culture enjoy, the famous Hula…
nuclear explosion the radiation cloud can cause diseases like cancer. It can also cause mutation which make life very hard. It can also cause nuclear winters if enough nuclear bombs are dropped. This would make temperatures drop 20 to 30 degrees celsius. Which would kill most plant life, one other thing it would do is cause air pollution. Another problem is we have way too many nuclear bombs. We have around 16,000 known nuclear bombs in the world. There are 4,800 alone in the US which is enough…
They were fed rabbit blood that was kept at a temperature of 37 degrees Celsius. This temperature was maintained because the blood was immersed in a water bath that circulated. The membrane that was used for the blood to be sucked through was a parafilm-membrane. The selected bugs were kept at a controlled humidity and temperature…
The search for a form of power that is almost completely renewable and its energy output far exceeds the energy required to start and maintain the reaction has been a focus for many years. Energies that are present today that involve burning things to produce electricity, such as coal, produce tons of pollution at a worldwide level. One of the newest energy sources being researched is a nuclear fusion reactor. This type of power generation has the ability to satisfy this search for a sustainable…
Case study one 1. Principle of APTT: Platelet poor plasma (PPP) is incubated at 37 degrees Celsius then phospholipid (cephalin) and a contact activator (e.g.: Kaolin, ellagic acid) are added followed by calcium (all pre-warmed to 37 degrees Celsius). Addition of calcium initiates clotting and timing begins. The APTT measures the time required to regenerate thrombin and fibrin polymers via the intrinsic and common pathways. Reagents: Platelet poor plasma (PPP) Surface activator: example;…
the atmospheric pressure exceeds one bar, the pressure found on Earth at sea level. Just above the "surface", since Uranus is a gas giant, of Uranus lies the troposphere. The temperature ranges from minus 243 degrees Fahrenheit (minus 153 degrees Celsius) to minus 370 F (minus 218 C), with the upper regions being the coldest. With temperatures like those it makes the atmosphere of Uranus one of the coldest in the solar system. Within the troposphere are layers of cloud;water clouds at the lowest…
