The Charge/Mass (e/m) Ratio of the Electron PHYS 0212: Introduction to Laboratory Physics Fall 2012 Abstract The experiment conducted demonstrated correlation between the charge and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found

Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Kidney Dialysis There are two types of kidney dialysis: Haemodialysis and Peritoneal dialysis Both types carry out the function of the kidney: filtering our blood of metabolic wastes. Kidney dialysis is necessary when someone suffers kidney failure. Failed kidneys cant perform their excretory function‚ but also cant regulate ion concentration‚ PH levels‚ and blood volume. Haemodialysis: (carried out 4 hrs every 2-3 weeks) -patient is connected to dialysis machine by two thing needles inserted

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

Dialysis Dialysis is a treatment for those with end stage renal disease (ESRD). Damaged or diseased kidneys cannot remove toxins from the body. Dialysis removes the toxins and regulates the pH of the blood when the kidneys do not work. Side Effects of Peritoneal Dialysis (PD) and Hemodialysis: * Side effects may be mild or severe‚ depending on the patient’s condition and whether or not they are following their dietary and fluid restrictions. * Infections Exchanges between the catheters
