The Plasma Membrane and Homeostasis


Homeostasis Maintaining a Balance

Cells must keep the proper concentration of nutrients and water and eliminate wastes.

The plasma membrane is selectively permeable it will allow some things to pass through, while blocking other things.

Structure of the Plasma Membrane

Lipid bilayer two sheets of lipids (phospholipids).
-Found around the cell, the nucleus, vacuoles, mitochondria, and chloroplasts.

-Embedded with proteins ....etc

Proton Exchange Membrane FuelCell Characterizationf or Electric
Vehicle Applications

ABSTRACT

This paper presents experimental data and an analysis of a proton exchange membrane fuel cell system for electric vehicle applications. The dependence of the fuel cell system s performance on air stoichiometry, operating temperature, and reactant gas pressure was assessed in terms of the fuel cell s polarity and power density-efficiency graphs. All the experimen were performed by loading the fuel cell with resistive heater ....etc

Abstract
Ultra Wide Band (UWB) sensors are one of the greatest inventions to provide high security for power plants, reservoirs and other critical infrastructures by detecting unauthorized intrusion. The principle behind these is they use high fractional bandwidth and low frequency of operation. Compared to other Doppler radars these have very high resolution because of wide band width, and these have good propagation through many materials because of low frequency of operation. Types of UWB sensors are UWB Ground Penetrating Radar (GPR) to k ....etc

Membrane Bioreactor for Wastewater Treatment

Recent technical innovation and significant membrane cost reduction have pushed membrane bioreactors (MBRs) to become an established process option to treat wastewaters. The combination of membrane separation with a suspended growth bioreactor is now widely used for municipal and industrial waste treatment (Judd, 2006). When used with domestic wastewater, MBR processes could produce effluent of high quality enough to be discharged to coastal, surface or brackish waterways or to be reclaimed for u ....etc
