LAB WRITE-UP NAME: Gabriel-Ohanu Emmanuel PARTNER: Baptiste Gilman TITLE: Graph Matching PURPOSE: The purpose of the experiment was to analyze the motion of a student walking along a straight line in front of the motion detector moving back and forward with different speed trying to match the graph provided. To also understand and interpret graphs of distance vs time and velocity vs time. To also know what the slopes of the each graph represent which tells how far the student travelled

compared to the homeogenous appearance of the nerve‚ and should be relatively easy to distinguish. If the optic nerve sheath is markedly dilated‚ it may be possible to diagnose this from visual estimation alone. In general‚ however‚ the software calipers should be used to ensure accurate measurement and recording. In severely raised intracranial pressure‚ it may be possible to visualisa a ‘crescent sign’(40)‚ an echolucent circular artefact within the sheath separating the sheath from the nerve due

A Study of Cellular Respiration & Gas Production in Peas We conducted this lab in order to determine the relationship between gas production and the cellular respiration rate between germinating peas and dormant peas. Cellular respiration is the procedure of changing the chemical energy of organic molecules into a form of energy that can be used by cells called ATP (adenosine tri-phosphate). Cellular respiration is conducted in 3 processes: Glycolysis‚ Citric Acid Cycle‚ and Oxidative

In order to determine the acidity of certain substances‚ we used moist and dry pH paper (litmus tests)‚ and observed the results. First we used dry pH paper to test the acidity of household ammonia‚ and it turned yellow. According to the legend‚ this indicates a weak acid. This is‚ however‚ not accurate as the vapor of the household ammonia wasn’t able to react as strongly with the pH paper since it was dry. Then‚ we used moist DI water pH paper with the same substance‚ household ammonia‚ and it

For example‚ paperboard differs by basis weight (or thickness as determined by caliper measurements) for a specified length of product. Additionally‚ paperboard may be uncoated or coated with an opaque‚ white clay-based material that masks cosmetic flaws and smoothes surface variability. Customers
