The technique of short bed--continuous development chromatography has been utilized to increase the separation of glycosphingolipids on high performance thin-layer chromatography plates. The theoretical goal of increasing separation of bands by decreasing solvent strength was achieved within a practical time span as a result of the high solvent velocities in the short bed tank. Examples are giv...

We introduce and analyze a general model of a population evolving over a network of selectively neutral genotypes. We show that the population's limit distribution on the neutral network is solely determined by the network topology and given by the principal eigenvector of the network's adjacency matrix. Moreover, the average number of neutral mutant neighbors per individual is given by the mat...

In rats after portacaval anastomosis (an animal model of chronic liver disease), transport of tryptophan and other members of the large neutral amino acid group from blood to brain was markedly enhanced. Increased transport activity was apparently restricted to the neutral amino acid transport system, since brain uptake of glucose, inulin, and tyramine was unaffected while blood-brain arginine ...

This paper deals with optimal control problems for dynamical systems governed by constrained functional-differential inclusions of neutral type. Such control systems contain time-delays not only in state variables but also in velocity variables, which make them essentially more complicated than delaydifferential (or differential-difference) inclusions. Our main goal is to derive necessary optim...

We calculated ideal-gas thermochemical properties (molar enthalpy, entropy, Gibbs energy, and heat capacity, Cp) for 30 primary 12 secondary alkanolamines their neutral, protonated, car...

At present, China is in the historical intersection period of "two centenary" goals. The realization "carbon neutral" goal has brought new opportunities for development China's energy sector. Based on GMM estimation method dynamic panel model, this paper studies relationship between consumption and industrial output by using provincial data from years 2008 to 2018. results show that impact coal...
