Induced Membrane Stresses Limit in Hydrotest Condition as per ASME VIII-2 E
2009-05-23 14:09:00 Why induced membrane stress limit in hydrotest condition is increased in Edition 2007 VIII-2 from 90% of Yield stress (Edition 2004) to 95% of yield stress (Edition 2007) ?? ? similarly why Pm+Pb limit is increased from 1.35 to 1.43 of Yield stress why???.....my guess is to take lower thickness of v

2009-05-02 21:45:00 hi all.. i wanted to get a sheet of either cell membrane, or any solid matrix embedded with a number of cilia fibrils.. the cilia should remain functional , i.e. should beat when ATP and other stimulants are added.
How can we know if the membrane dryer is still working?
2009-01-12 03:05:00 How do I know if the Membrane dryer is damaged or not? As we noticed that the purge loss is getting higher and higher as time goes by, to the extend that our compressor does not cut-off. can a membrane dryer be serviced? we are using it with an oil-less compressor, and the prefilter is a 0.01

iKey's Membrane Keyboard
2008-05-19 07:46:00 Industrial hardware manufacturer iKey has just announced a new keyboard addition to its rugged hardware portfolio. The new device features a waterproof rubbery membrane that is said to keep water off the delicate circuitry inside.According to the company, the device is especially built for industrial environments with increased humidity and dust. It is also equipped with a hardcoated, textured, polyester film that offers increased ruggedness to the conventional silicone rubber keypads."What's great about the membrane keyboard is there are no crevices," said Joel East, Director of Technical Design at iKey. "If you're working around processing byproducts, grease, or other things that might accumulate between the keys of a regular keyboard, you can just spray it down and know that it's clean," East continued.The keyboard's design includes raised, mechanical snap-dome keys with an integrated Synaptics touchpad, similar to the notebook mouse trackpad. Therefore, the keyboard can subs...

Remember To Protect Your Reverse Osmosis Membrane
2007-11-29 14:35:00 Water quality in the aquarium is of upmost importance and the aquarist needs to do everything they can to ensure that the water qualty does not drop to below par levels. Water quality is measured in many ways with probably one of the most important being the water which is used to mix with the salt - in this instance reverse osmosis water. The majority of reverse osmosis units are made up of numerous stages. Each of these stages has a function the main one of which is the membrane. The other stages used are normally along the lines of a pre-filter (sometimes called a sediment filter), a carbon filter and a DI stage. The pre-filter and the carbon filter are normally located prior to the membrane and the DI unit located after the membrane.
