The fluid mosaic model of the cell membrane. What is the fluid mosaic model? The fluid mosaic model is a model conceived by S.J. Singer and Garth Nicolson in 1972 to describe the structural features of biological membranes. The membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid‚ but more like a ’fluid’. The membrane is depicted as mosaic

Buffers‚ and pH‚ and Diffusion oh my The pH of a solution is the measure of the concentration of charged Hydrogen ions in that given solution. A solution with a pH lower than seven is considered to be acidic. A solution with a higher pH is a base. It is very important for organisms to maintain a stable pH. Biological molecules such as proteins function only at a certain pH level and any changes in pH can result in them not functioning properly. To maintain these constant pH levels‚ buffer solutions

Abstract Case Services’ software provides production optimization for a variety of different methods of artificial lift. This paper discusses the dominant factors in electrical centrifugal submersible pump design and monitoring. Emphasis is placed on three areas: • • • Well inflow performance behavior. Fluid Pressure-Volume-Temperature and phase behavior. Pump equipment

regulation. When someone has to be placed on dialysis their body goes through a process that waste products are excreted from our bodies artificially by a process called diffusion. This process of removal of waste products in a healthy person is facilitated by kidneys. People that is diagnosed with kidney failure experiences problems with waste removal this is where dialysis comes into place. People with renal failure and are in the process of dialysis have been known to have several homeostatic

Introduction Medical textiles‚ also known as biomedical textiles‚ are textile products and constructions for medical and biological uses‚ e.g.‚ first aid‚ clinical‚ or hygienic purposes. (SASMIRA‚ 2007) The term medical textile literally means textile used for medical purposes. Textile apart from being a vital part human life is long since been used in medical field‚ though the term has been coined very recently. Textile materials have wide range properties such as flexibility‚ elasticity‚ strength

M.D. Stegall in “A Curious Chain of Events” acknowledges that chain transplants or PKD can save certain death of renal patients on dialysis whereby granting them an allograft donor kidney bypassing the long wait on the UNOS deceased donor list. This impact of removal from UNOS also allows another potential recipient to be moved up on the UNOS list. Alison Tierney states in “Gift or

most common form of transplant after the corneal one is the kidney transplant. It is the most effective and efficient way of resuming kidney function in the body caused due to kidney failure (various causes) and is proven to be more effective than dialysis. The number of people waiting for a kidney transplant is growing and the number of kidney donors is decreasing rapidly. The sale of kidneys has spawned a raging debate regarding its legal‚ ethical and economical implications. To know the debate‚
