EXPERIMENT-2 NAME OF THE TEST: HARDNESS TEST AIM : OBJECT TO DETERMINE HARDNESS TEST OF A METARIAL INTRODUCTION It become necessary to test engineering materials before they are accepted for processing‚ buying or applying to determine whatever or not they meet the spefications required. One of the tests is hardness test. The Rockwell and brinell machines are those most commonly used for this purpose. PROCUDURE AND LABORATORY REPORT 1. Understad thoroughly

· Alpha-1 level test – determines the amount of Alpha-1 Antitrypsin in a persons’ blood. To confirm the severity of the disease other tests may be done such as‚ chest x-rays and Computerized Automatic Tomography (CAT) scans. The chest x-ray examination may reveal a barrel-shaped chest. Also‚ listening to the chest with a stethoscope

bromide (polybrene) test in blood cross matching? Watch out! Abstract: BACKGROUND: Blood cross matching test mainly includes manual hexadimethrine bromide (polybrene) test (MPT) and the automatic analyzer method (by coombs card) at the Department of blood transfusion. Generally instrumental method is used for large quantities of samples. It can save manpower; MPT is used for emergency and few samples. it can save time. Our department recently encountered a case of cross match blood test by MPT was negative

Flame Test Lab Introduction/Purpose: When a certain amount of energy is supplied within an atom‚ the electrons of that atom begin to move up the levels of electron configuration. This level of energy is called a quantum. The object of this experiment was to examine the movement of electrons up and down energy levels through the use of given elemental substances. With heat supplying a large amount of energy‚ the properties of the elements caused them to give off a certain color or tone of

Josh Huggard Mr. Neale SBI3U1 November 6th‚ 2014 Spit and Armpit Lab Partners: Kara Washer and Josh Young Abstract This lab shows the use of salivary amylase with strong and weak starch mixtures to break down complex carbohydrates into simpler sugars. This lab was conducted to physically see the breakdown of carbohydrates into simpler sugars (glucose‚ fructose‚ galactose) using the salivary amylase enzyme. This is extremely important to all metabolic functions in the human digestive system. It

Complexometric Determination Of Water Hardness By Angelica Aquino CHM 152 LL January 5‚ 2013 METHODS: 1. Prepare an approximate 0.004 M disodium EDTA solution. To prepare this solution‚ weigh about 0.7-0.8 g of Na2EDTA and dissolve in 500 mL deionized water in your plastic bottle. Make to to shake the bottle to dissolve the salt. 2. Obtain a 250-mL Erlenmeyer flask and transfer a 10 mL of CaCO3 using a buret into the flask. 3. Measure 30 mL of deionized water and add it into

Hardness of Water by EDTA Titration Introduction Water hardness is caused by natural minerals that are dissolved into the water‚ predominantly calcium and magnesium‚ and is measured as the equivalent concentration of calcium carbonate (in milligrams per litre). Water hardness is usually noticed because of difficulty in lathering soap and the formation of a scum in the bathtub. Ca2+ and Mg2+ form insoluble salts with soaps causing precipitation of the soap scum. Another effect of hard water

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

Materials and Equipment – Slump Test 3. Slump Test 4. Materials and Equipment - Vebe 5. Vebe Test 6. Conclusion 1. Introduction The purpose of this laboratory was to first test the effect that increasing water content would have on the workability of fresh concrete‚ completed by way of a slump test. The second part of the laboratory was to check what the influence of a superplasticiser would have on workability of fresh concrete‚ this was completed by completion of a Vebe test. 2.
