In the coming years, estimates of the glomerular filtration rate (GFR) may replace the measurement of serum creatinine as the primary tool for the assessme... LA Stevens,AS Levey 被引量: 13发表: 2014年 Frequently asked questions about fractals In this lecture we will try to address the "...
2) Filtration is an important part ofchemistryas it deals with the separation of materials of different chemical composition. A solvent is taken into account which has the ability to dissolve one component, while not dissolving the other. 3) Filtration is widely in use as one of the key unit...

Techniques of ecological engineering are given with examples that include maintaining biodiversity with multiple seeding, experimental mesocosms, enclosed systems with people like Biosphere 2, wetland filtration of heavy metals, overgrowth and climax ecosystems, longitudinal succession, exotics, domestication ...
(>140 kDa) from small proteins and peptides. However, except with specialized columns and equipment, these techniques alone cannot purify antibodies from other proteins and macromolecules that are present in typical antibody samples. More commonly, g...
Concentration(Chemistry)VelocityThe document is concerned with new methods of filtration for aircraft fuel systems, presenting a study of the vortex separator principle. The report discusses its basic principles of operation and the calculated performance of the separator in specific engine fuel systems....
The measured filtration efficiency was most sensitive to changes in face velocity and particle charge. Relative to the NIOSH method, users of the ASTM F2299/F2100 method have commonly used non-neutralized (highly charged) aerosols as well as smaller face velocities, each of which may result in ...
(detergents), biocides (antimicrobial agents) and protease inhibitors. Different salts, denaturants, reducing agents and chaotropes may also be included. After filtration or centrifugation to remove the cellular debris, typical samples wi...
This review covers sample acquisition and handling, virus recovery/concentration, and the determination of targets using molecular biology and mass-spectrometric approaches. The concentration methods discussed include precipitation, antibody-based concentration, and filtration; the detection methods discussed ...
it cannot automatically achieve the standard effect of in-situ leaching and filtration. The advantage of the ectopic impregnation method is that with the help of corresponding machines, the soil is loosened and mixed with the impregnation solution. After mixing, the treatment effect is very good,...
