چکیده
Currently, the general trend of global fishing industry is to increase production fish food products not only due development aquaculture, but also biological characteristics body sturgeon. The aim study was theoretical justification and practical implementation assessment growth beluga juveniles their hybrids with sterlet aged 0+ 2+ (three-year-olds) in industrial Krasnodar Territory. determined: mass, live weight gain, linear growth. By end control cultivation, experimental groups 1728.3 2236.4 g, respectively. In group, absolute 2198.2 while group it 1692.2 g. difference average daily gains 0.71 g favour hybrids. length 32.7 37.3 cm. positive effect heterosis had a on first- generation crossbreeds obtained from sterlet.

" Environmentally Friendly " Way!
We discuss how to implement an " environmentally friendly " renormalization in the context of finite temperature field theory. Environmentally friendly renormalization provides a method for interpolating between the different effective field theories which characterize different asymptotic regimes. We give explicit two loop Padé resummed results for λφ 4 theory for T > T c. We examine the impli...

متن کاملSocially Responsive, Environmentally Friendly Logic
We consider the following questions: What kind of logic has a natural semantics in multi-player (rather than 2-player) games? How can we express branching quantifiers, and other partial-information constructs, with a properly compositional syntax and semantics? We develop a logic in answer to these questions, with a formal semantics based on multiple concurrent strategies, formalized as closure...
