VARIOUS LAB TEST ON CEMENT: Checking of materials is an essential part of civil engineering as the life of structure is dependent on the quality of material used. Following are the tests to be conducted to judge the quality of cement. 1. Fineness 2. Soundness 3. Consistency 4. Initial and Final Setting Time of Cement FINENESS OF CEMENT: We need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The principle of this is that we determine the proportion of cement

substrate is brought into the catalase and broken apart into water and oxygen. This process may be able to happen naturally‚ but the enzyme‚ catalase‚ speeds up the process.

proteins that catalyze metabolic reactions vital for the survival and functioning of cells [1]. Without enzymes‚ metabolic processes would occur at unfeasible rates. Catalase is a naturally occurring enzyme that breaks down hydrogen peroxide into water and oxygen; it is essential to cellular respiration. I asked if enzyme activity was affected when exposed to different conditions‚ such as temperature‚ substrate concentration‚ and pH levels. My first hypothesis is that higher temperatures amplify

The end product of the process will produce urine‚ which contains mainly water and a range of substances that such as inorganic salts‚ organic compounds and some metabolites. The quantity and composition of the urine reflects various biochemical processes that occur in the body. Thus‚ the composition of the urine of an individual

Wanni Lin Biology 110 March 2‚ 2015 DNA Lab BACKGROUND In this laboratory experiment‚ students were introduced to DNA electrophoresis. DNA electrophoresis is an instrument that many forensic scientists use to get a DNA fingerprint as an evidence for crimes. Not only can it be used for forensic science‚ people can use this for paternity test‚ as well as look for evolutionary relationships among organisms. Agarose is used to make the gel that the DNA fragments are going into. Since DNA particles are
