Lusian - dichotomous data model as a finite sequence of independent Bernoulli trials with, generally speaking, different probabilities of success. The tasks of statistical hypothesis testing, classification, averaging lusians are discussed. In accordance with the requirements of practice the problems are considered primarily in the asymptotic behavior of increasing dimension, in which the number of unknown parameters increases in proportion to the size of data. The method of testing hypotheses on set of small samples and the theory of unbiased statistical estimates were proved to be useful
In this article we discuss a version of the metric theory
of the fundamental interactions in which it is assumed
that the physical constants due to the presence of extra
dimensions of space-time. The estimation of the
number of physical constants based on the theory of
supergravity in 112D is that the minimum number of
constants is equal to 222, and the maximum number -
1404928. At present, the number of parameters that
characterize the elementary particles, isotopes and
chemical elements is about 150920. This number is 9.3
less than the maximum possible number of parameters
that indicate still great potential of modern science.
Functions describing the area and volume of a unit
hypersphere, embedded in a Riemannian space of
arbitrary dimension, were used to find the fundamental
physical constants. A satisfactory agreement with a
relative error of 0.03% calculated and experimental
values of the fine structure constant found out. For the
ratio of the average mass of a nucleon to the electron
mass is obtained coincidence with the experimental
value with an accuracy of 0.002%. The proposed
theory of physical constants different from that Bartini
theory that established the optimal dimension of the
space is a hypersphere 5 and 7, rather than 6 as in
Bartini theory. The problems of the compactification
of extra dimensions in describing the motion in fourdimensional
space-time are discussed
In the article, we have suggested a general mathematical model of non-stationary and non-isothermal process of a binary electrolyte transfer in dilute solutions in an electro-membrane system (EMS), taking into account the joint action of gravitational convection, forced convection and electro convection in potential dynamic mode. This model is a boundary problem for a system of two-dimensional quasi-linear Navier-Stokes equation and Nernst-Planck-Poisson in partial derivatives equation. We have developed a theory of similarity of the process of heat and mass transfer in electro-membrane systems, specifically, in a desalting channel of electro dialysis apparatus, taking into account joint actions of concentration polarization, space charge, gravity convection, forced convection and electro convection. It is shown that the criterion of electro convection does not directly depend on the initial concentration, and, therefore, electro convection occurs at any initial concentration. At the same time, the criterion of concentration convection linearly dependents on the initial concentration, and, therefore, at high concentrations, concentration convection prevails, while at lower concentrations, the role of gravitational convection begins to fall whereas the role of electro convection increases. The theory of similarity of the process of heat and mass transfer in the desalting channel of electro dialysis apparatus built in this work taking into account the joint action of concentration polarization, space charge, gravity convection, forced convection and electro convection is important for engineering calculations, for scaling the results of experiments in an electro-membrane cell for industrial electro dialysis water desalting apparatus
This article is about the theory of social motivation as a tool to increase social performance in Sub Saharan countries. So in the first part we will retell the theoretical understanding of motivation and its limits and then the explanation of the concept of social motivation as an alternative to complete the existing and old form of motivation. The second part of the article will talk about social performance and how to measure it. Several techniques are available for measuring performance of an employee. But the difference is in the sources of traits or qualities to be appraised. Jobs are different and have different requirements and different opinion of the management too. The practice is difficult sometime because of different kinds of workers (factory workers, executives or salespeople), which cannot be measured with the same indicators all the time. In this article we will see some theoretical and practical models of performance appraisal based on effectiveness and efficiency at work with concrete indicators. Also the readers will understand how social motivation, when well used in a company can increase the performance and transform the work place into a livelihood place for all stakeholders. And the article will end with the conclusion in which we have a piece of advice and literature references
The completely closed model of wall turbulence was derived directly from the Navier-Stokes equation. The fundamental constants of wall turbulence including the Karman constant have been calculated within a theory. This model has been developed also for the accelerated and non-isothermal turbulent boundary layer flows over rough surface
Numerical solutions of equations system of turbulent transport of admixtures in a surface layer of the atmosphere and for a large scale have been studied
The model of continuous transition from the laminar flow to the turbulent flow is proposed and the theory of the spectral density of turbulent pulsation is given

Blood samples were taken from newborn calves and sent to the Rostov regional veterinary laboratory. The result of the general analysis of blood showed increased erythrocytes, increased red blood cell count and increasing white blood cell count as well as low hemoglobin levels. The results of the studies on the content of phosphorus, calcium, zinc, vitamins A and C in the blood showed that the sick calves have hyperphosphatemia, namely violations of the phosphorus-calcium ratio. A decrease in vitamin A in sick calves to 8.2±0.5 mcg% and zinc to 74.1±1.2 mcg% was found .This indicates a violation of mineral metabolism, which occurs due to a lack of minerals in the diet, but also with intensive withdrawal from the body, as a result of poor absorption and impaired renal filtration. As a result of typing on O-antigen, using a set of polyvalent and serogroup agglutinating O-coliseums, the presence of an adhesive A20 antigen was revealed. In the course of research, faeces from 9 newborn calves of 1-8 days of age were sent to determine the sensitivity to antibacterial drugs. Thus, 9 samples of cultures of E. coli sensitive to the following antibiotics: enrofloxacin, imipenem, meropenem, levofloxacin, and vancomycin, gentamicin, cefotaxime, and rofloxacin. Based on data from blood tests and sensitivity to anti-biotics, the animals were divided into 3 groups. And each group used three different treatment regimens. Observing the calves of the experimental groups, we found that the condition of the sick animals stabilized within 2-4 days. In the first group of 12 calves, 1 calf fell and 11 survived. In the second group of 11 calves, all survived. In the third control group of 12 calves, 7 fell, and 5 survived. When determining the sensitivity of Escherichia cultures isolated from calves of this farm to antibiotics, 100% sensitivity to levomycetin sodium succinate was obtained
The important historical feature of the period examined by us was that the economic events of party and state, conducted in an agrarian sector in his chronologic scopes, were aimed at the correction of defects of former politics in the village conducted from the beginning of collectivization. Politics of soviet guidance in area of agriculture in 1958-1964 carried contradictory enough and inconsistent character. From one side, it fully realized the necessity of changes for this sphere, with other, it could not renounce political and ideological principles and to give large freedom to the peasantry
