balance or scale used in testing fine and coarse aggregates shall have readability and accuracy as follows: For fine aggregate‚ readable to 0.1 g and accurate to 0.1 g or 0.1 % of the test load. For coarse aggregate‚ or mixtures of fine and coarse aggregate‚ readable and accurate to 0.5 g or 0.1 % of the test load. 2. Sieves – the sizes and apertures appropriate to the specification of the material being tested‚ complying with BS 410: For coarse aggregate‚ standard sieve size of 50.0 mm‚

no need for distillation. Next‚ a solubility test was given. When one drop of the unknown liquid was added to about 2 mL of water‚ the sample was tested to be soluble due to the dissolubility between the two compounds. By following the chart that was given on the sheet‚ the pH of the solution was tested. Since the two litmus did not changed color‚ the sample was identify to have a low molecular weight and a neutral substance. Based on the solubility test‚ some possible

· 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

The experiment was separated into four stages‚ the first being preparation of cell competency. In this stage two vials were placed in ice baths‚ one vial containing 50 µL of E. coli and the other containing a CaCl2 solution. 630 µL of the CaCl2 solution was then transferred to the E. coli vial‚ using a sterile pipet. After tapping the tube to mix the solution‚ it was then returned to the ice bath to continue incubation for at least 10 minutes. The cell competency preparation was carried out by the

Abstract There are many methods employed to precipitate proteins out of solution. In this experiment we manipulated many physical and chemical variables in order to achieve purification of a protein via precipitation. In the first part of the experiment we purified the protein casein by modifying it’s pH. In the second part of the experiment we manipulated the ionic strength of albumin in egg whites‚ in a process called salting out. By manipulating these chemical properties we were able to

“Use of Biuret Reagent to Test for Proteins In Food” Cindy Zhou Introduction Protein is a series of amino acids that are connected together by peptide bond. The bond is located between the end of previous amino acid‚ which is the carboxyl group‚ and the head of next amino acid‚ which is a amino group. The Biuret reagent is a solution of copper sulfate and potassium hydroxide. When peptide bond are presented‚ the copper (II) will interact with them (MadSci Network: General Biology). It is

Lab #4: The Immune System Purpose: The purpose of this lab was to perform and understand the procedures of conducting an ELISA test to determine whether a particular antibody is present in a patient’s blood sample through a virtual simulation. Hypothesis: If I successfully complete this lab‚ I will then understand how to perform an ELISA test‚ the purpose an ELISA test‚ and also how to interpret the results of this test.

Report on Receptor Proteins According to Abedon (2012)‚ receptor proteins are intracellular proteins‚ or protein fractions‚ that have a high specific affinity for binding a known stimulus to cellular activity. Receptor proteins may be located at cell surfaces or within the interior of cells. They may detect hormones or instead keep track of what otherwise is going on in cell ’s environment. They may be enzymes or serve to relay the occurrence of signal reception in other ways such as by opening
