Calcium is essential to health yet it holds a hidden danger that brings us to our graves much quicker then we would like. Calcium is the most promoted nutrient by proponents of conventional‚ nutritional‚ and alternative medicine. This is a great and tragic mistake. They should have been promoting magnesium. Magnesium deficiency leads to an increase in myocardial levels of both sodium and calcium. This is a problem because Coronary Artery calcium is a predictor of near-term coronary heart disease

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

The purpose of this experiment was to test how effective certain homogenates were as buffers. Buffers are devices that keep pH within maintainable boundaries so something can function. When something is too basic (has too much OH-) the buffer adds H+ and vice versa in order to create water to keep the pH at an acceptable range. Each group (I was with William Yung for this experiment) was tasked with testing one homogenate. The homogenate tested by our group was liquid spinach. Each team added HCl

Solubility is the ability of a substance‚ or solute‚ to dissolve and homogenously disperse throughout another substance‚ or solvent. In order for drugs to be therapeutically effective and bioavailable‚ it must first be highly soluble. Poor solubility and low dissolution rates of drugs in the aqueous gastrointestinal tract lead to decreased bioavailability. Solubilization of poorly soluble drugs is a challenge in the formulation of newly developed drugs. Because many medications are administered orally

By measuring the reaction rate between bleach and the dye‚ the order of the reaction was determined to be first order. Introduction The study of kinetics is important for studying the amount of time it takes for a particular reaction to reach

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚

below this number is categorized as acidic and urine with a higher pH is alkaline. pH is playing a important role in the development of renal calculi. Acidic urine will lead to xanthine‚ cystine uric acid‚ and calcium oxalate stones. However alkaline urine can cause calcium carbonate‚ calcium phosphate‚ and magnesium phosphate stones. For protein‚ normally there will be no protein or only small amount of protein in the urine‚ Protein in the urine may be a sign of kidney disease. If the result finds

Lab Report Diffusion is - One of two kinds of passive transport‚ - Diffusion can transport ions from higher concentration to lower concentration region without any other forces. - A net movement of molecules in and out of cell membrane - Diffusion can be affected by the steepness of the concentration gradient. Lab question: Is the rate of diffusion influenced by the presence of second molecule? Prediction: the rate of diffusion is influenced by the presence of second molecule
