Description
Researches were spent in the conditions of the branch of FGBOU VPO «Orenburg State Agrarian University » of the Ilek zoo technical school and on the chair of noncontagious illnesses of animals at Orenburg State Agrarian University. The absolute and relative growth of the weight of a pancreas in ontogenesis was studied. All facts are subjected a statistical processing and during development the absolute and relative growth of the weight is established

PECULIARITIES OF GROWING NOMINALLY PURE AND NEODYMIUM DOPED STRONTIUM TUNGSTATE SINGLE CRYSTALS
01.00.00 Physical-mathematical sciences
Description
The Nd3+ doped and nominally pure SrWO4 single crystals have been grown by modified Czochralski method. The nature of thermo physical behavior of the growth system with an additional afterheater for crystals with different light transmission was shown. The distribution of Nd3+ ions along the obtained crystals was investigated, the effective distribution coefficient was equal to 0.71

01.00.00 Physical-mathematical sciences
Description
In the article, a text is considered as a system, which includes both verbal and nonverbal subsystems of different levels of hierarchy. System generalization of the classical Shannon measure of information in text and a quantitative measure of the level of systematic text, called the "coefficient of emergence of Shannon", which is based on it, is proposed. This article shows mathematical relationship between the obtained coefficients of emergence of Hartley in 2002 and Shannon's proposed rate of emergence. It is shown that every object of cognition can be associated with a text reflecting its composition and structure. The process of learning from this perspective is seen as a process of constructing a text object models of learning and research process of these models. The definition of procedures for encryption and decryption, as well as quantitative measures of their effectiveness based on quantitative measures systematic texts is given. From this standpoint, the relationship of encryption and decryption with zipping and unzipping is shown. We propose a computer program for the numerical measurement of systemic and specific texts of the simulated systems and present some numerical examples in this article
