Another lab partner should prepare a test tube with 10 mL of the lactose solution and 1 mL of the lactase solution. Take caution in measuring the solutions. Label the tube with lactase and lactose as being Tube Two and cut off an appropriate amount of paraffin wax paper to cover the opening of the tube. Press the paper tightly to the tub and turn upside down several times. Wait for six minutes (timer is suggested) so that the solutions are properly mixed. During the wait, prepare two…

LDL-c, VLDL-c, alanine aminotransferase (ALT) and aspartate amino transferase (AST), alkaline phosphatase (ALP), blood urea nitrogen (BUN), uric acid and creatinine were purchased from ELIPSE, United diagnostic industry, UDI, Dammam, Saudi Arabia. Paraffin oil, carbon tetrachloride (SpectrosolW BHD chemicals ltd pool, England) and other chemicals and solvents were of highest grade commercially available. Camel’s milk Camel’s milk samples were collected daily…

4.2.3.5. Antioxidant assays in gastric tissue homogenate 4.2.3.5.1. Catalase activity Catalase activity in the gastric tissue was measured according to the procedures of Sinha (1972). One ml of homogenate solution was taken and mixed with 5 ml of phosphate buffer of pH 7.4. To this 4 ml of 0.2 M H2O2 was added and time noted. Exactly after 180 seconds of adding H2O2, a set of 1ml of reaction mixture from the above was taken and 2 ml dichromate acetic acid was added. It was then kept in a boiling…

Candles are made up of chemical compounds pressed together in the form or a candle. They are made of two totally different types of wax which is Paraffin wax and Beeswax. The Paraffin candles are 95% of the world’s population of candle production. But when it comes to the beeswax the beekeepers can only used one or two pounds of the wax for every hundred pounds of honey they are able to harvest. They are also thought being able to clean the air because when the beeswax candle is burned it…

With the recent advances in the economic and industrial sectors in India, the energy demand has been reaching its peak. The conventional methods of power generation using fossil fuels are not only adequate, but also leading to environmental pollution. The predominance of fossil fuels in Indian electric power generation leads to 40 percent contribution to the total carbon emissions cite{Ghosh02}. So in order to suffice the growing energy demand with minimal emission of the greenhouse gas (GHG),…

James Chadwick was a Physicist during the 1900’s who was born and raised in England. He attended Manchester High School and Manchester University. He then was awarded the Exhibition Scholarship and attended a school in Berlin, Germany. This placed him in Germany at the very beginning of World War I, where he was held a civilian prisoner of war for four years. Once he was finally free, he returned to England to work with Ernest Rutherford in Cavendish Laboratory at Cambridge. Together, they were…

Magic Shell has a “secret ingredient”. 1. Magic Shell’s “secret ingredient” is edible-grade paraffin wax, or a colorless soft solid. 2. Magic Shell isn’t the only food product that uses this ingredient, chocolate uses edible-grade paraffin wax for the shiny effect produced. B. Magic Shell has a special way of using this ingredient as well. 1. Magic Shell makes sure the ingredient is kept warm before using. 2. Magic…

Equal amounts of water, hexane, and ethyl alcohol were added to the test tubes and mixed thoroughly. The solubility of the sample was observed and noted. This procedure was repeated using Naphthalene and paraffin as the solutes. Density determination Mass of a beaker was measured. Then, a volume of 10mL of the unknown substance was placed into the beaker and the mass of the beaker and the sample measured. Using the obtained mass of the unknown liquid, its…

Daniel DiMarcella Dr. Margaret Bryans BIT 120 December 6th 2016 Biofuels: Are they the Future? Everything humans need come from our planet whether it is food, water, metals or fuels. It has been determined that if we use up any one of these resources then we will be without forever. Fossil fuels, coal, oil, and natural gas are non-renewable resources. Formed from plant and animals that lived up to 300 million years ago, fossil fuels are found in deposits deep beneath the earth. The fuels are…
