How did the amount of Sodium Citrate‚ an anticoagulant‚ added to a Calcium Chloride solution affect the volume of the clots formed when a sodium alginate solution‚ a blood simulation‚ was introduced? Mackenzie Keesor (Fall Semester 2017-2018) Purpose The purpose of this experiment was to observe the differences in the formation of simulated blood clots when different amounts of sodium citrate‚ an anticoagulant‚ was added to the coagulation process‚ which would help gain information about the process

II. Rationale The history and usage of ink can be traced back to the 18th century B.C.‚ with the utilization of natural plant dyes‚ animal and mineral inks based on such materials. Ink is a pigment in a liquid form or paste form used as colorants and dyes. Ink provides much of the color on paper in the modern world and has many uses in different cultures around the globe. Also‚ they are becoming more and more expensive because of their increasing purposes. Although ink is universally available

Synthesis of Isopentyl Acetate (Banana Oil) Using A Fischer Esterification Reaction Purpose: The purpose of this experiment is to synthesize Isopentyl Acetate using a Fischer esterification reaction. Fischer esterification is an acid-catalyzed condensation of an alcohol and a carboxylic acid‚ yielding an ester and water. Isopentyl Acetate has the scent of banana oil‚ once synthesized it will be purified by distillation. Then the analysis of the sample using H NMR and IR will determine purity

To remove copper penicillamine‚ zinc salts and/or trientine are used. Galzin is used to get rid of some physical symptoms of the Wilson’s disease. It is necessary to take 50MG of Galzine three times a day for it to work properly. Sometimes Zinc Acetate is given to block the absorption of extra copper. It is also necessary for a person with Wilson’s disease to have a different diet. They often have a depletion of pyridoxine or B-6 and need supplements of 25MG daily. The food they eat should stay

INTRODUCTION Sodium hypochlorite is considered one of the most efficient irrigant in endodontics 1-4. Due to its antimicrobial‚ tissue dissolving properties and low cost‚ it is one of the most widely accepted irrigant in Endodontic practice 5-8. Sodium hypochlorite as a solution is relatively an unstable compound. On exposure to organic compounds‚ heat‚ light‚ air and metals‚ the available chlorine ions reduce and there is subsequent loss of tissue dissolving and antimicrobial properties 9-10. Recent
