The New Principle of Transformation Heat into Electricity

The overall scheme of heat-to-electric power conversion in a closed thermally inhomogeneous heterogeneous flow with a constantly renewable local imbalance is investigated. A high-speed motor-generator is rigidly linked with a propulsor in the conversion system. Propulsor is a revolving vessel that contains the liquid phase of the working ingredient. It has nozzles on it that…

Frequencies of Genotypes and Alleles of the K232A Substitution in the DGAT1 Gene in Four Cattle Breeds of Russian Selection

The enzyme DGAT1 is involved in the synthesis of triglycerides. The most well-known polymorphic variant of the DGAT1 gene is substitution of lysine with alanine at position 232 of the protein (K232A). The 232K allele is associated with increased enzyme activity and a higher content and yield of fat in milk. There is less data…
