Abstract

The object of the present paper is an analysis of factors causing considerable variability of functional systems (P. K. Anokhin) in their efferent part. This variability concerns the structure not only of different movements but has been established as well for similar repeated (cyclic, in particular) movements during work performed with the same working power. The problem of variability of the functional systems in fatigue is discussed.

Severity of illness and the welfare effects of moral hazard.

The extent to which the moral hazard caused by health insurance represents economic inefficiency has been the subject of much debate. This paper incorporates health status in a model of moral hazard, and finds that seriously ill patients are likely to exhibit greater moral hazard than healthier patients but the proportion of moral hazard that is inefficient declines with the severity of illness. Because of these competing tendencies, the cost of resource misallocation is parabolic in the severity of illness. The effect of the consumer's initial wealth endowment is also considered.

Improved production of ethanol by deleting FPS1 and over-expressing GLT1 in Saccharomyces cerevisiae.

To improve ethanol production in Saccharomyces cerevisiae, two yeast strains were constructed. In the mutant KAM-3, the FPS1 gene, which encodes a channel protein responsible for glycerol export, was deleted. The mutant KAM-11 had the GLT1 gene (encoding glutamate synthase) placed under the PGK1 promoter while having the FPS1 deletion. Growth rate and biomass concentration remained virtually unchanged with the mutant KAM-11, compared to that of the parent. Over-expression of GLT1 by the PGK1 promoter along with FPS1 deletion resulted in a 14% higher ethanol production and a 30% lower glycerol formation compared to the parental strain under anaerobic fermentation conditions. Furthermore, acetate and pyruvic acid formation was also reduced in order for cells to maintain redox balance.
