Description
The article presents results of the study on the use of associations of probiotic bacteria in black-and-white breed calves. We have analyzed the effect of associations of probiotic bacteria on hematological (red blood cells and white blood cells, hemoglobin and hematocrit) and blood biochemical parameters at calves. It was found that the associations of strains of Bifidobacterium bifidum DSM 20456, ATCC 29521, and Enterococcus faecalis H22; Bifidobacterium bifidum DSM 20456, ATCC 29521 and Enterococcus faecium UDC 86 do not have significant changes in the basic blood parameters of the animals, while improving some of counts during their use

DescriptionIn 1893, the French mathematician J. Adamar raised the question: given a matrix of fixed order with coefficients not exceeding modulo this value, then what is the maximum modulo value can take the determinant of this matrix? Adamar fully decided this question in the case when the coefficients of the matrix are complex numbers and put forward the corresponding hypothesis in the case when the matrix coefficients are real numbers modulo equal to one. Such matrices satisfying the Hadamard conjecture were called Hadamard matrices, their order is four and it is unknown whether this condition is sufficient for their existence. The article examines a natural generalization of the Hadamard matrices over the field of real numbers, they are there for any order. This paper proposes an algorithm for the construction of generalized Hadamard matrices, and it is illustrated by numerical examples. Also introduces the concept of constants for the natural numbers are computed values of this constant for some natural numbers and shown some applications of Hadamard constants for estimates on the top and bottom of the module of the determinant of this order with arbitrary real coefficients, and these estimates are in some cases better than the known estimates of Hadamard. The results of the article are associated with the results of the con on the value of determinants of matrices with real coefficients, not exceeding modulo units

Description
After analyzing scientific papers on the topic of many scholars, the author focuses on the situational approach as a major factor of the organizational aspects of the investigation planning by an investigative team in cases of multi episode complex collective crimes. It has been suggested that the planning and organization of the investigation is preceded by the predictive assessment of the investigation situation, determination of the pattern of a detective’s actions and programming and simulation of the investigation process. All processes require the implementation of organizational and administrative activity of the head of the investigative team. However, the initial investigation planning for one or more crimes is reduced only to a description of the investigative situations, to the presentation of a list of investigative actions and operational searching activities without the agreed plan and appointment of the participants in such activities. Consequently, the situational approach in planning can minimize errors during investigative activities and optimize the work of the investigative team dealing with the multi episode crime particularly complex in terms of investigative and procedural actions and operational and searching activities
