The aim of the research is to study influence personality traits and life path on rate biological aging adults, depending their gender age. Methods: diagnostic (questioning path, self-esteem personality, determination age) statistical (automatic neural networks). Subjects: 987 people (including 575 women) aged 35-70 years from various regions Russian Federation. Continuous target variable: rela...

Various surveys of low-mass binaries in star forming regions have been performed in recent years. They reached opposite conclusions concerning possible binary excesses in some of these associations. I develop a consistent method to reanalyze all these studies, so that I can compare all data consistently, and understand the previous findings. I also report the detection of five new companions to...

Auxotrophic mutants of Bacillus subtilis need much higher concentrations of the required adenine, nicotinic acid, riboflavin, thiamine, or tryptophan for optimal sporulation than for maximal growth. Acetate can partially replace thiamine, indicating the importance of the pyruvate dehydrogenase system for differentiation. A glycerol-requiring mutant can sporulate only if its cells contain a smal...

Zn complexes of proline, lysine and arginine are efficient catalysts for the aldol addition of p-nitrobenzaldehyde and acetone in aqueous medium, giving quantitative yields and enantiomeric excesses up to 56% with 5 mol% of the catalysts at room temperature.

Maintenance Supply Chain (MSC) involves Maintenance, Repair, and Overhaul (MRO) organizations and the relationships within and across suppliers and customers. These organizations work with the probability of equipment failure, maintenance, and the use requirements of spare parts. All of these elements increase uncertainty in this environment. Besides, it is difficult to integrate and process in...
