01.00.00 Physical-mathematical sciences
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

NUCLEI SHELLS AND PERIODIC TRENDS
01.00.00 Physical-mathematical sciences
Description
Parameters describing periodic trends in the formation of nuclear shells have been established based on the theory of nuclear interactions and data on the binding energy of nucleons for the set of known nuclides

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

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

NUTRITION AND HEALTH OF HIGH-PRODUCTIVE COWS
Description
It this article, the situation in dairy practice with nutrition factors caused metabolic diseases such as ketosis, acidosis, lameness and a decline in fertility is shown. The article has the proposes on the nutrition of highly productive cows in transition period

A NEW METHOD OF THE RAGWEED INHIBITION (AMBROSIA ARTEMI-SIIFOLIA L.) OF SOUTH RUSSIA
Description
Adventive weeds control using classical approach of biological protection against adventive species is not always satisfactory. A new method of the ragweed inhibition is developed that is based on shifting of the natural phenological stage of the phytophage growth. It makes possible to produce a large group of ragweed noctuidae under laboratory conditions on an artificial nutrient medium and to inundate weed infested areas with them by the time of the invader emergence
