The glass tubing must be dry before experimentation to easily see the white ring inside. 2. What are the possible sources of error? • If the cork is not properly placed. • The tubing wasn’t dry before the experiment. • Human error in measuring the distance at both sides. • Wrong computation.

Title: Purification of Egg white protein Name: Michael Johnson Partner: David Logad & Nandita Date: 2nd 9th September 2004 Group: Thursday 11:30am - 3:30pm Introduction Salting Out In 1888 Hofmeister that it can be possible to dehydrate a protein by adding salt to the solution‚ salting out. When a protein in a aqueous solution it is surrounded by water‚ in fact there can be up to 0.35g of water tightly bound to 1g of protein (Simpson 2004). Also the effectiveness of the salting out

In the humus lab were were trying to find out if hydrogen peroxide would cause a reaction and show us the amount of humus in the soil by putting gas into a graduated cylinder with water to make the water level lower therefore showing us how much humus the material being tested contained. It showed that the sand was lacking humus but the mushroom compost was the most rich in humus. My hypothesis was correct because I predicted that the mushroom compost would produce the greatest amount of humus out

The dialysis treatments or transplanted kidney will take over some of the work of your diseased kidneys and remove wastes and extra fluid from your body. This will improve many of your symptoms. Transplantation has many advantages. It eliminates the need for dialysis and helps patients enjoy a life filled with more freedom‚ energy and productivity. Although most patients are on

Two weeks later‚ the patient again presented to the same outside hospital where she was still found to be bacteremic and her dialysis catheter was exchanged for a second time in which a left subclavian dialysis catheter was placed. After placement of the dialysis catheter‚ the patient had three incomplete dialysis sessions that were cut short due to patients complaint of chills and shortness

reached. The steeper the gradient the faster the rate of diffusion. There are a few types of diffusion. Three (3) of those are: Facilitated Diffusion- refers to diffusion of substances across a cell membrane with the help of transport protein. Dialysis- refers to the diffusion of solutes across a semipermeable membrane. Osmosis- refers to the diffusion of the solvent across semipermeable membrane. The concept of diffusion is widely used in physics (particle diffusion)‚ chemistry‚ biology‚ sociology

into the urine. If a person experiences kidney failure‚ waste products can’t pass out of the blood‚ which causes waste to build up in their bodies. While a patient can choose to replace their kidney with a working one‚ dialysis is also an option in cases of kidney shortage. Dialysis provides the same functions a kidney does. It clinically purifies the blood as a replacement for the lost kidney‚ by separating the particles in a liquid of the basis of differences in their ability to pass through a membrane

AKNOWLEDGEMENT During the reflective study‚ there a lot of partier giving helpful hand to make and finish my reflective study. Therefore‚ it will be unfair if I put a side their contribution rather. Firstly‚ the special thank goes to my helpful Staff Nurse Suhaini. The supervision and support that he gave truly help the progression and smoothness of the internship program. Also thanks for your skill and knowledge that you have thought me in the progress of completing my research. The skills and
