Arsenic contamination and possible remediation Victoria Reyes Texas A&M International University Abstract Arsenic can be found in many places on Earth. This includes from natural sources and as a by-product from different anthropogenic activities. The fact that arsenic can be found so commonly on Earth has lead to the contamination of several countries’ drinking water. This has put many people at risk for arsenic poisoning. There are many complications that come from the continuous ingestion…

3.4.2.1 Test for milk:- 1. Determination of SNF in milk AIM: - to determine the SNF of milk Apparatus: - lactometer jar, lactometer and thermometer Principle: - It is calculated by using lactometer method. Procedure:-  Warm the milk sample to 40 to 45oCand maintain at this temperature till 5 min.  Mix the contents by rotating and inverting the bottle, taking care to avoid the formation of air bubbles.  Cool the sample to 15.5oC  Invert the sample bottle 2 to 3 times; pour enough milk into…

The genitals are a warm, damp region of the body which is conducive to the presence and transmission of many bacteria, virus, and yeast pathogens such as Syphilis. It is an infectious venereal disease; the microorganisms spread during intercourse as a result of exchanging reproductive fluids or bleeding, from mother to unborn child, when lesions come in contact with broken skin, and through blood transfusions. The disease is caused by Treponema pallidum which originates from the spiral-shaped…

Glycerol consists of three alcohol groups. Fatty acids can be attached to these two groups to form mono glycerides (one fatty acid), di glycerides (two fatty acids) and tri glycerides (three fatty acids). 3.3 Why vegetable oil as a lubricant? Vegetable…

Thermoplastic starch is a biodegradable polymer mixture which is biologically degradable and has also a great mechanical and thermal properties. Thermoplastic starch is made by blending starch with a plasticizing agent such as sorbitol or glycerol to make thermoplastic melt. This is why thermoplastic is non harmful to humans, it contains non toxic materials which are easily compostable and biodegradable. On the other hand, DINP is toxic and not compostable or degradable. Jelu-Werk is a toy…

Role, and Structure,” 2003) It is not a solid. Some of the things the plasma membranes need in order to carry out it’s functions is lipids, proteins, and carbohydrates. They move freely and fluidly in the plane of the membrane. Lipids, made up of glycerol, two fatty acid tails, and a phosphate- linked head group, are used to make a barrier between the cell and its environment. Phospholipids are the main fabric of the membrane. Cholesterol is placed in between the hydrophobic tails of the…

Breaking down the chemical, there is a liquid called Propofol that is injected but only a certain amount can be taken. A persons weight determines that. The ingredients contained in Propofol are soybean oil, egg lecithin, and glycerol. Propofol has a milky, white appearance and the effects it produces are hypnosis and the absence of pain. Another liquid called Sevoflurane, is made into a vapor by a machine. Highly fluorinated, Sevoflurane is used as an anesthetic in surgery today…

Introduction The purpose of this lab was to identify the lipids in an egg yolk and to identify the amount of lipids in milk [1]. To extract the lipids from the egg yolk, the egg yolk needed to be combined with an organic solvent such as a mixture of CHCl3/MeOH. An organic solvent was needed to carry the extracted lipids up the TLC plate because the plate was polar, due to the presence of silica gel (silanol groups). To compare relatively similar lipids to the ones found in the egg yolk, the egg…

Introduction: Centrifugation is a process used to separate or concentrate materials suspended in a liquid medium. It is a method used to separate molecules under the centrifugation field based on their sedimentation rate with the help of centrifugal force. It is also used to measure the physical properties of a molecule like molecular weight, density, shape, etc. If it is used for the separation of one type of materials from others is termed as preparative centrifugation and when used for…

High fructose corn syrup is a simple carbohydrate also known as a monosaccharide. Sweet corn kernels are harvested and converted into starch by using caustic soda. Typically, cornstarch is 93% to 96% glucose. Because pure corn syrup is not sweet enough for food manufacturing, food processors add Enzymes to convert glucose into fructose, which changes the molecular structure. The exact ratio of glucose to fructose depends on the manufacturing process. Researchers from Princeton University…
