Minimal deformations of the commutative algebra and the linear group GL(n)

We consider the relations of generalized commutativity in the algebra of formal series $M_q (x^i )$, which conserve a tensor $I_q$-grading and depend on parameters $q(i,k)$ . We choose the $I_q$-preserving version of differential calculus on $M_q$ . A new construction of the symmetrized tensor product for $M_q$-type algebras and the corresponding definition of minimally deformed linear group $QGL(n)$ and Lie algebra $qgl(n)$ are proposed. We study the connection of $QGL(n)$ and $qgl(n)$ with the special matrix algebra \mbox{Mat} (n,Q) containing matrices with noncommutative elements. A definition of the deformed determinant in the algebra \mbox{Mat} (n,Q) is given. The exponential parametrization in the algebra \mbox{Mat} (n,Q) is considered on the basis of Campbell-Hausdorf formula.Comment: 14 page

Adaptation features of sheep of the Edilbaev breed reared in the agroecological conditions of the arid zones of Southern Russia

Aim. The aim of the research was to study the features of formation of adaptive  ability, meat productivity and quality indicators of mutton obtained in the arid conditions of the Volga region from sheep of the Edilbaev breed of different genotypes. Material and Methods. A package of teaching materials has been developed concerning an increase in the productive qualities of different genotypes of the studied  breed in the conditions of arid regions of southern Russia.   Results. The authors’ research has demonstrated the high adaptive abilities of animals of the Edilbaev breed, their economic and biological qualities, food and taste  indicators of their meat, as well as the possibility of further development of the  breed in the arid conditions of southern Russia. As a research base, we selected the  Volgograd‐Edilbay LLC breeding farm (the world's only breeding and genetic center  for raising Edilbaev sheep) which is located in the Volgograd region and specializes  in breeding pure‐bred animals in arid steppe, semi‐desert and desert zones. Due to  the great demand for the livestock of this breed from farms located in arid territories, this study of the comparative aspects of production characteristics of animals  of original and new types in the arid conditions of the Volga region is of interest to  both science and practical animal husbandry.   Conclusion. An assessment of the nutritional value of mutton obtained from animals of the Edilbaev breed has shown its high nutritional and biological qualities

Isolation of a human lactoferrin biosimilar from frozen milk of goat producers

This study offers an additional source of information on isolation and purification of the human lactoferrin biosimilar from frozen milk of goat producers. Thanks to the application of an improved technique of raw material degreasing, a milk filtrate with complete absence of the fat part was obtained, which as a result had a favorable effect on the yield and properties of the finished product, whose quality was confirmed by methods of MALDI-TOF mass spectrometry and microbiological analysis. As a result 135 g of human lactoferrin biosimilar was obtained from 75 liters of frozen milk
