Diabetes mellitus is a growing problem across the world. By the year 2010, it was estimated that over 221 million people would be afflicted with the disease. Type 1 diabetes is the result of absolute insulin deficiency and is treated through the addition of exogenous insulin. Type 2 diabetes, non-insulin dependent diabetes (NIDDM), is characterized…

Abstraction Fourier-transform infrared spectrometry has been really utile in assisting scientists analyzing molecules of HCl and DCl. Because heavy hydrogen has a greater mass than H. the IR set shown for HCl is at a higher wavelength than DCl. The soaking up of visible radiation in DCl was at lower frequence 1700-2200 cm-1 because D…

ynthesize my own aspirin Analyse the purity of my aspirin samples (aspirin and recrystallized aspirin) compared to commercial aspirin by use of analysing melting points, TLC plates and colorimetry tests Investigate how pH effects the rate of hydrolysis of aspirin Background theory Making my own sample of Salicylic acid (to then be converted into Aspirin)…

Table of Contents Abstract Introduction Aims Theory Apparatus Procedure Result Calculation Discussion Conclusion Recommendation References Abstract The growth kinetic of microorganism in shake flask is studied using Escherichia coli as a sample. Microorganism in different volumes is transferred into 250ml Erlenmeyer/shake flasks containing nutrient media. The effect on the constant volume of media used is…

Introduction: The Diels-Alder reaction is a [4+2] cycloaddition of a conjugated diene and a dienophile. This type of reaction was named for Otto Diels and Kurt Alder who were the first to investigate this reaction (Weldegirma, 2012). The Diels- Alder reaction is one of the most important reactions in all of organic chemistry because of…

The ruddy chou index shows how a usual family merchandise such as ruddy chou can do a suited index and be able happen out if a chemical is either and acid. base or impersonal. Acids are a chemical that reacts with an base neutralizing it bring forthing H2O and a salt. Acids are besides normally…

Purpose: The purpose of this lab is to utilize, demonstrate, and understand the various techniques and procedures used in gravimetric labs. Specifically, we will apply our scientific knowledge of gravimetric procedures to determine the chloride content in an unknown soluble salt. The concept of this theory is to determine the chlorine content in a specific…

A uninterrupted moved armored combat vehicle reactor ( CSTR ) is a uninterrupted reactor that runs at a steady province. They are used most often with liquid stages. but can manage gas or solid reactions as good. No affair what the reactants are or the merchandise is. all CSTR’s have the same constituents. There is…

Magnetic particle testingNon destructive metal testing Magnetic particle testing involves a non destructive method of testing to detect imperfections on top of the metal or below its surface. This is usually an easy and very reliable means of detecting and locating of faults such as cracks on metal’s surface.The procedure; a flux is ran through the…

The end for this lab was to find the conditions that demonstrate what chemicals in musculus fibres are necessary for contraction and which 1s prevent musculus contraction from happening in a simplified system in order to find the minimal demand for contraction. Methods In order to fix musculus fibres, a individual yarn was obtained from…
