Electrochemical Aspects of Microfiltration and Ultrafiltration,distribution and pore structure. However, such membranes cannot be understood simply as sieves. Neither in this context can the materials to be separated, particles, colloids, microbial cells or proteins, be sufficiently characterised in terms of size or molecular weight. In particular, the electroc可商量 发表于 2025-3-27 07:49:27
The Use of Pervaporation in Biotechnology, mass separation task, generally referred to as ‘downstream processing’, is often particularly difficult. As stated by Wang (1987) this is because most microbiological processes are carried out in dilute solutions with the actual product in rather low concentration in mixture with large amounts of wplasma 发表于 2025-3-27 12:19:58
WB without proteinase digestion. The amino acid sequence of PrP of Japanese deer was found to be the same as sequence as the one reported for mule deer. These antibodies were then used for CWD surveillance in Japan. When 127 of hunter-killed deer from Hokkaido were examined, PrP. was not detected in any of the animals.Hemiparesis 发表于 2025-3-27 16:32:08

Gases rising from the ground in a waste tip can be piped away and the carbon dioxide separated from the methane by a membrane process allowing the methane then to be used as a fuel, simultaneously saving energy and reducing the greenhouse effect sinceGNAT 发表于 2025-3-28 05:06:30
