2013/2014 Assignment 1 (10 marks) Answer ALL the questions. 1. Discuss briefly fluid mosaic model for membrane structure. (6 marks) Answer: The lipids and most of the protein in the plasma membrane are free to bob about‚ sliding from one location in the membrane to another. Because lipids and proteins move about laterally within the membrane‚ the membrane is a fluid mosaic of lipids and proteins. The membrane fluid is since the composition of any location on the membrane can change. In the same

Class: DME2 Title: Flow Measurement Date: 11/02/2013 Lecturer: Mr Higgins Summary: In this experiment many different meters were used to measure fluid flow rate; the orifice plate‚ the venture meter‚ the rota meter and the weigh tank. Each meter works by its ability to alter a certain physical property of the flowing fluid and then allows this alteration to be measured. The measured alterations are linked directly to the flow rate and these measurements are subbed in to adjusted equations

Fluid Catalytic Cracking Fluid catalytic cracking* (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling hydrocarbonfractions of petroleum crude oils into more valuable [1][2][3] gasoline‚ olefinic gases and other products. . Cracking of petroleum hydrocarbons for conversion of heavy fractions into lighter fractions was originally done by thermal cracking which has been almost completely replaced by catalytic cracking because

Although a significant distinction exists between liquids and gases‚ both types of fluids obey the same laws of motion. In most cases of interest‚ a fluid can be regarded as continuum‚ i

P4 – Explain the role of the kidney in the homeostatic control of fluid balance Homeostasis is how our body works to keep the internal environment constant. The kidneys play a role in the control of fluid balance. For this assignment I will be discussing the gross anatomy of the renal system and the kidney. Renal System The renal system is a group of organs that work together to produce‚ store‚ and release urine. It consists of 2 kidneys‚ ureters‚ the urinary bladder‚ urethra and renal vessels which

laboratory sessions are compulsory course-work. You must attend them. Should you fail to attend either one you will be asked to complete some extra work. This will involve a detailed report and further questions. The simplest strategy is to do the lab.] Notes For the First Year Lecture Course: An Introduction to Fluid Mechanics School of Civil Engineering‚ University of Leeds.
