results in severe dehydration and even death. The cholera toxin causes chloride ion protein channels in the plasma membranes of the small intestine epithelial cells to open. Causing chloride ions to move into the lumen. The build up of chloride ions lowers the water potential in the lumen. Water then moves out of the

ORIGINS OF INTERNATIONAL LAW PRELUDE: Man is a social animal‚ in the past it has been living in caves‚ as the time passed man gradually became civilized and started living in communities. In past there were no laws and rules to be followed by the human being. In the long march of mankind from the cave to the computer a central role has always been played by the idea of law- the idea that order is necessary and chaos inimical to a just and stable existence. Every society has a framework of

a clear blue solution of sodium and copper salts. In presence of simple sugars‚ the blue solution changes color to either green‚ yellow or brick-red‚ depending on the amount of sugar. Method 1) Mix smalls amount of each food sample (i.e.‚ Egg lumen‚ cylindrical piece of potato tuber‚ bread crump and crisps) in different test tubes with distilled water to make a liquid test. Take another test tube with glucose solution to act as a control so as to compare the difference in color after the completion

(Learn About LED Bulbs). An L.E.D. bulb gives about 100-110 lumens per watt. They last about 35‚000-100‚000 hours.(Vakil). This research is relevant to my experiment because I am trying to determine which light bulb is a better choice overall. I think that if the lights are given the same amount of energy and are

Data Projectors Amy Shipman $50- $66‚525 What is a data projector? It is “a device that projects computer output onto a white or silver fabric screen that is wall‚ ceiling or tripod mounted." The three most common types of data projectors are the LCD‚ DLP‚ and the LCoS. Each type of projector will project your audio and video‚ they just have different ways to process the output of your audio and video. DLP stands for Digital Light Processing. This type of data projector has a light that

Then take another glow stick (same brand) and make sure you crack the controlled variable glow stick and this glow stick at the same time and put them both in 20 degrees Celsius water and just leave the controlled variable one alone. The temperature of the water is the manipulated variable. The amount of light in lumens is the responding variable. Then add ice in the beaker until the temperature

the plaque cap tears ( ulcerates‚ fissures or ruptures)‚ allowing blood from the lumen to enter the inside of the plaque itself. The core with lamellar lipid surface‚ tissue factor ( which triggers platelet adhesion and activation ) produced by macrophages and exposed collagen‚ is highly thrombogenic. Thrombus forms within the plaque‚ expanding its volume and distorting its shape. Thrombosis may then extend into the lumen and cause reduction in lumenial diameter which then develop into stenosis or blockage
