III. RESULTS AND DISCUSSIONS: A. Characteristics of Aluminum-Graphite composites and the in-situ reaction To examine the reaction condition of carbon flakes and Al powders, 4 wt. % carbon flakes were added to Al powders. Fig. 1 shows the DSC plot obtained during heating and cooling of the green compact from room temperature to 750 0C and from 750 0C to room temperature at a heating/cooling rate of 3 0C /min under argon gas atmosphere. From the DSC heating curve it is evident that the total…

The physiochemical properties of this combination tablets were assessed through the evaluation of uniformity of tablet weight, thickness test, hardness test, friability test,disintegration test, dissolution test and potency test according to the standard method. They have generally two type of test. First compendial test and another one in non compendial test. Compendial tests are test methods that…

ANALYTICAL METHODS Determination of λ max Gemifloxacin mesylate λ max is determined by preparing one standard concentration of 10μg/ml and scanning should be done. Preparation of 0.1N HCL 8 ml of hydrochloric acid is taken in 1000ml volumetric flask and dissolved with distilled water and then make up to 1000ml with distilled water. Standard graph of Gemifloxacin mesylate: The λmax of Gemifloxacin mesylate in 0.1N HCL was scanned in UV-Visible Spectrophotometer and found to have maximum…

and indicate which are physical properties and which are chemical properties. Zinc is a silver-gray—colored metal that melts at 420 oC. When zinc granules are added to dilute sulfuric acid, hydrogen is given off and the metal dissolves. Zinc has a hardness on the Mohs scale of 2.5 and a density of 7.13 g/cm3 at 25 oC. It reacts slowly with oxygen gas at elevated temperatures to form zinc oxide,…

The crisis that unfolded in Flint, Michigan is not an isolated one. The United States has had an extensive history of using lead in water systems and not knowing just how dangerous it was, especially when using in very soft, acidic waters. In the beginning of the 19th century, lead pipes were already commonly used for service lines directly to residences because of its malleability and durability. Unlike iron or galvanized steel, lead could be easily bent around obstructions and it was highly…

How do I pick out a foam roller? Probably the most common question people ask themselves, before purchasing a foam roller. Allow me to share a 7 step guide, that will help you make the best choice. I wish a had this guide, when i picked up my first one. It would have helped a whole lot with the process of selecting the correct one. 1. Try one. Before buying one, try one first. It can indicate if it's something for you, and also give you a better idea of the things you might seek from it. 2.…

whatever reason, been considered inappropriate, and its removal from library shelves has been requested.” Second, are banned books. A banned book is actually removed from shelves. “I saw nothing, but heard much through the closed closet door” “Hardness, Hardness! Wetness, Wetness!” As I read this it struck me as something an adult book would read and this therefore justifies my reasoning for this book only being portrayed to a certain age group. “Even Tanzania is better than Vietnam.” This and…

in the water and the hardness of the water. Three hach kits were used to measure three different properties of the water of the stream. The Dissolved Oxygen hatch kit was used to measure the dissolved oxygen in the water. The Nitrate hach kit was used to measure the Nitrate (NO_3) in milligrams per liter. The Phosphate hach kit was used to measure the Phosphate (PO_4) in the stream water also in milligrams per liter. The LaMotte hardness test kit was used to test the hardness of the water. An…

Preformulation Study Preparation of calibration curve of Amoxicillin trihydrate [51,53,76] Preparation of stock for Hydrochloric acid Stock solution in 0.1N Hydrochloric acid (0.1N HCl): 10 mg of Amoxicillin was accurately weighed and transferred into 10 ml volumetric flask. It was dissolved and diluted to volume make up to mark with 0.1N HCl to give stock solution containing 1000 µg/ml, after than 1ml take to from 1000 µg/ml and dilute to volume make up to mark of 10ml volumetric flask with…
