LEDs… Release only ONE color of light Produce very little heat What is an LED? They are semiconductor devices that can convert electrical energy directly into light due to the nature of the bonding that occurs in the semiconductor solid. Type of bonding is directly related to conductivity of solid. Bonding in Elemental Solids Electronegativity – the ability of an atom to attract electrons to itself. Atoms with low e.n. (metals) don’t hold valence electrons tightly valence

CASE STUDY: LYME DISEASE Cherron Boswell‚ Denise Colton‚ and La Nita Hood Bowie State University Introduction Lyme disease is the most common tick-borne disease in North America and Europe. Lyme disease is steadily increasing in the United States and the majorities of health care providers are unfamiliar with the disease; primarily because of its complexity and as a result lack the clinical skills necessary to provide comprehensive care to infected patients. The purpose of this

What is Transfer Factor In the first critical days of life for humans and other mammals‚ a mother passes on vital immune knowledge through the first meal—colostrum—which contains transfer factor molecules. As nature’s first supplement‚ these memory molecules transfer immune experience to educate and prepare the newborn’s immune system to function in the world. While vitamins and herbs provide nutrition to the immune system‚ transfer factors provide information so immune cells can do their

Coffee Green Coffee- Before coffee is roasted‚ it is referred to as “green coffee”. The green coffee is primarily made up of caffeine‚ lipids‚ carbohydrates‚ proteins (amino acids)‚ and organic acids (although inorganic acids exist in coffee as well). These groups are quite stable in the green phase‚ and it is the carbohydrates‚ proteins‚ and acids that will undergo significant reactions during roasting to produce coffee. The important groups of carbohydrates in beans are from the monosaccharides

Problem Set 1 Solutions: Chapters 1 1 Cell sizes: E. coli is a cylindrical bacteria with 1 M wide and 2 M long. Liver cells are approximately spherical with a diameter of 20 M. Plant palisade cells are cylinders 20 M wide and 35 M long. A) Calculate the volumes of each cells? A) Since E.Coli is cylindrical Volume of a cylinder = r2h‚ where r is half of bacterial width/diameter = 1M/2 = 0.5M and h is the length of the bacteria

02 December 2012 1. Title and Author 1. The Effect of Extreme Temperatures on the Rate of Photosynthesis 2. Jeffrey Xia 2. Abstract A previous lab in which we conducted‚ tested whether or not the light intensity had an effect on the rate of photosynthesis. We concluded that light intensity did possess an effect on the rate of photosynthesis – the closer the experimental plant units were to the light source‚ the more experimental plant units exhibited the effect of gas exchange in photosynthesis

Liver Disease and Medium Chain Triglycerides Seth Fraley Liver disease encompasses numerous disorders which disrupt the normal functions of the liver. Normal liver functions include: breaking down harmful substances‚ removing waste products from the blood‚ storing nutrients and vitamins‚ and moderating chemical levels in the body. Types of liver disease include: viral hepatitis‚ autoimmune diseases (primary biliary cirrhosis)‚ genetic diseases (hemochromatosis)‚ alcoholic hepatitis‚ and non-alcoholic

Outline and evaluate the role of neural mechanisms in controlling eating behaviour (24 marks) Today there is enormous interest in the psychological factors that can affects a person’s eating habits‚ but some of the clearest research findings have come from research into the brain (neural) mechanisms controlling eating behaviour. One important mechanism to consider is the role of homeostasis in all mammals. Homeostasis is how the body maintains a constant internal environment. Our diet is essential
