A BLOOD ALCOHOL MEASUREMENT DEVICE USING A FIXED FREQUENCY PHOTOSPECTROMETER BY LUCILLE J. DURFEE ABSTRACT There are many people who go out for a night on the town without thinking about the potential dangers of drinking alcohol and then driving. A simple, non-invasive system is needed to test these people before they leave the bar to determine if they are “okay” to drive. The purpose of this project is to study, design ,build, and test a fixed frequency photospectrometer that will test the blood

Experiment 1 Determination of the Acetic Acid Content of Vinegar. Goal: During this experiment you will gain experience in working with volumetric glassware, and gain knowledge on how to determine the uncertainties in the volumes delivered by these. In addition, you will use a suitable titration to determine the concentration of acetic (ethanoic) acid in vinegar samples. Objectives: On completion of the laboratory you should be able to: Demonstrate proper techniques for using `pipette

Rebecca Walker Forensic Toxicology CRJ 311 Dawn George 4/22/2013 History Forensic science is defined as the application of science to the law. There are different types of forensic science, and each plays an integral part in the criminal justice system. Forensic biology usually involved DNA testing and its results. Forensic anthropologists examine human remains that have become skeletons in an attempt to determine how long the remains have been in a location and to try to determine a

Rate of Fermentation (How Yeast Get Energy) Purpose: To study how the rate of fermentation by yeast cells is affected by the concentration of molasses. You will be using yeast cells (microscopic organisms) and molasses (a product of photosynthesis in sugar cane). You will measure the rate of fermentation by measuring how much carbon dioxide (CO2) is given off by the yeast cells over a certain period of time. Materials Goggles 6 test tubes (18mm x 150 mm, for example)

A : DETERMINATIOPI OF CRUDE FAT OF SUNFLOWER USING SOXHLET APPAATUS ABSTRACT 11e objective of this practical was to determine the crude fat content of sunflower through semi continuous method using Soxhlet apparatus where by 5g of the sample was weighed in to extraction thimble and placed in to the extraction chamber. Then heat was applied to the flask containing the extraction solvent (ethyl ether) and the solvent builds up in the extraction chamber for 5 to 10 minutes and completely

solution (25ul/25ml ddH2O) to each well of a 6-well plate (23ul/3ml or 15ul/2ml Vb). Working conc of VB is 2 ug / ml. 4. Incubate cells 2 – 3 hours in 37oC incubator. 5. Meanwhile, put one bottle of sterile ddH20 and one 50ml tube filled with 70% Ethanol in fridge (4C). Also, put one box of slides at –20C. 6. 45 minutes prior to hood work, put hypotonic solution, 1x PBS, and wash media (DMEM + 5% FBS) in 37C water bath. 20 minutes prior to hood work, put trypsin in 37oC water bath. 7. After 2-3

characterized by excessive consumption which leads to feelings of increased anxiety and other negative emotional states.Consequently, these emotions lead to further consumption.Similar to human alcoholics, ethanol- dependent animals show signs of anxiety like behaviors and self administrate ethanol during periods of withdrawal. CRF, also known as corticotropin releasing factor helps mediate the increased anxiety during withdrawal.Additionally,regions of the amygdala are comprised of the CRF system

"This method measures the alcohol content by volume of any wine,spirit,or beer,using a hydrometer, giving readings as accurate as an ebulliometer used by commercial wineries. The method is based on the research of Dr. William Honneyman,Ph.D." 1.Measure the SG of the wine you wish to test.We will call this figure SG-1. 2.Measure exactly one pint of the wine (500ml).We will call this the sample. 3.In a enamelled or glass pan,boil the sample down to about half it's original volume.This drives

ETHYL CELLULOSE Ethyl Cellulose polymers are derived from cellulose. They inert, high purity powders with no caloric value and are virtually colorless, odorless and tasteless. According to the DOW films made from ETHOCEL (a brand name of Ethyl cellulose) polymers are highly flexible and retain their flexible and retain their flexibility at temperatures well below freezing. It is excellent as a film former. Films made from it are tough, with high tensile strength and unusual
