Health and Safe Legislation and Regulation You are required to research two different engineering environments that you have come knowledge of. It may be best if one is an electrical environment and one a mechanical environment. For each of these environments: • Identify a minimum of four different sets of regulations that would be relevant • Describe a minimum of three key features of each of the sets of regulations you have chosen. Mechanical Provisional and Use of

LABORATORY REPORT FOR BIO411 Experiment 5 : Cellular Respiration Experiment 6 : Photosynthesis Title: Cellular Respiration Objective: To observe and determine cellular respiration in yeast/onion cells. * Measure respiration rate using different substrates. * Measure respiration rate at different temperature. Introduction: In this laboratory experiment‚ we are given 3 task. The first one is respiration in yeast. Second is respiratory indicator and the third one is observing

We recorded our findings on the table labeled table 1. Table 1 shows the transmittance at each wavelength on a table from 400 to 720. The information on Figure 1 came from the leaf extract on the paper chromatography that we used; with the help of acetone we saw the spectrum and the differences of the different pigments. Percentage transmittance in Table 1 show that the lower the number‚ the more dense that solution is at that specific wavelength. As the numbers get higher‚ the less dense it is and

Name of NMR solvent used and its chemical shifts: Acetone-d6‚ the chemical shifts are 29.9 and 206.7 for 13C Questions: 1. 2. The phenol group of methyl salicylate is a weak acid‚ therefore it reacts very swiftly with a strong base‚ in this case NaOH‚ to form a sodium

Title: Freezing and Melting of Paradichlorobenzene Purpose: Melting‚ freezing‚ and boiling points are properties that can easily be determined and help in identifying a substance. These properties can be found in chemical literature ad reference tables‚ and can be used to distinguish a pure substance from many other pure substances. In this lab you will use the pure substance Paradichlorobenzene and determine its melting an freezing points by warming and cooling a sample of the substance

Desiccation of the phenol-killed cells with ’acetone did not provide a satisfactory cell preparation. Such cells gave variable results and were difficult to resuspend properly. It was assumed ’that ’ acetone influenced the ’sensitivity of M. lysodeikticus by reason of its fat
