Membrane switch technology is a highly reliable interface solution with many advantages. The sealed nature of the overlays makes membrane switch technology an excellent front panel solution where environmental concerns are an issue. The success of any membrane switch design effort is facilitated by effective communication between the design engineers and the vendor. This design guide is intended as an outline for communicating the requirements of our customers to Nelson Nameplate Company. A mutual understanding of the technology is very benefic ....etc

The advent of membranes makes the wastewater treatment easier nowadays. Activated sludge process (ASP) , which is the oldest technique in wastewater treatment , is combined with highly efficient membrane filtration to start a sophisticated technique called Membrane Bioreactor (MBR).It is an efficient process for maintaining a long solids retention time(SRT) at a relatively short hydraulic retention time(HRT),which is needed for the treatment of waste water. MBR is favored to all other conventional techniques because the treated water is free fr ....etc

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 chlorop ....etc

The application of Membrane Bioreactor (MBR) in waste water treatment is widespread. The Membrane Bioreactor process consists of a suspended growth biological reactor combined with a membrane unit located either external to the bioreactor or mounted within the bioreactor. Nowadays researchers have been exploring the use and extend of their applications for treatment of municipal and industrial waste waters. It is an efficient process for maintaining a long solids retention time(SRT) at a relatively short hydraulic retention time(HRT).While a hi ....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 perfor ....etc
