6.5.5.1Energy-efficient sequences of simple columns When amulticomponent mixtureis to be separated into three or more products, a sequence of two or more simpledistillation columnsis needed. Once the sequence of separations is selected, each simple column could be designed for energy efficiency, co...
aBase nematic mixtures were modified with various other two, three and four rings aromatic fluorinated compounds in order to evaluate the relationship between BP stability and molecular structure of mixture components. 基本的向列的混合物修改以各种各样的二种,三种和四种圆环芳香fluorinated化合物为了评估BP...

In all exposure conditions, 76% of transcripts were down-regulated (196/256) vs 23% (60/256) upregulated (Fig. 3a). Strikingly, few differ- entially expressed transcripts were common to two or more periods of exposure; that is the majority were specific to single exposure periods (Fig...
growth promotion14,15,16; though, undesirable influences of some microbes were also documented17. The utilization of probiotics of multi-species as feed additives is perhaps more effective than monospecies in terms of higher adhesion and multiplicity of antimicrobial compounds on the intestinal mucus...
One can see from [Equation 12.1] that td is an increasing function of the sample thickness L. As a result, one can distinguish two distinct kinetic regimes, depending on the relative predominance of the previous steps: 1. Regime 1: Evaporation (or dissolution)-controlled kinetics. In the cas...
About one-quarter of drugs are composed of a racemic mixture of two isomers that often have different pharmacodynamics, pharmacokinetics and toxicity. The racemate can be problematic, especially when the adverse effects of the combination are due to the least active enantiomer. Isolating and developin...
