Metabolic syndrome is one of the causes of gestational diabetes, along with which dysfunctional deviations develop in all types of metabolism, which is accompanied by the formation of numerous obstetric complications. The aim of this investigation is to study the influence of the initial (lateral behavioral profile) and the forming gestational asymmetries (placental lateralization) of the female body on the nature of carbohydrate and lipid metabolism in pregnancy. In a longitudinal retrospective study, using a modified Annette test, the patients with the right behavioral asymmetry profile were selected, of which, depending on the lateralization of the placenta, 3 clinical groups were formed: right-oriented placentation, ambilateral placentation and left-oriented placental. The content of lipid fractions and the parameters of carbohydrate metabolism was determined by means of biochemical and enzyme immunoassay. It has been established that as the gestation period increases, there is an increase in insulin resistance and an increase in the atherogenicity coefficient, which is statistically significantly prevalent in women with counter-directional orientation of gestational asymmetries (patients with the right lateral behavioral phenotype) and the forming gestational asymmetry (left-oriented placental arrangement). The most pronounced changes in metabolism in right-handed women are noted in the case of the left-oriented placenta, mediating afferent impulses in the right non-dominant hemisphere of the brain, which is metabolism-associated. This category of women has the highest risk of obstetrical pathology.

Authors of this research study space-time characteristics of movement of the athlete with a bar when performing squat in powerlifting with burdening of 50%, 60%, 70%, 80%, and 90%. The obtained data are compared with data of bio-electric activity of previous researches. It has been established that increase in burdening of more than 50% leads to change in space-time order of bar movement. Changes have been found on the site of the trajectory characterizing a space-time order of bar movement upward. At the same time a part of the trajectory characterizing a space-time order of bar movement down is stable at all applied burdenings. Comparison of data on change in space-time order of bar movement and the indicators of bioelectric activity of skeletal muscles presented in earlier published works allows us to state that increase in burdening leads to change in coherence of work of skeletal muscles that changes a space-time order of bar movement.

Bone metastasis is a common sequella of solid malignant tumors such as prostate, breast, lung, and renal cancers, which can lead to various complications, including fractures, hypercalcemia, and bone pain, as well as reduced performance status and quality of life. A multidisciplinary approach is usually required not only to address the etiology of the pain and its complicating factors but also to treat the patient appropriately. Currently, the treatment of bone pain remains palliative at best with systemic therapy (analgesics, hormones, chemotherapy, steroids, and bisphosphonates) as well as local treatments (such as surgery, nerve blocks, and external beam radiation). Bisphosphonates, which inhibit osteoclast-mediated bone resorption, are standard care for tumour-associated hypercalcaemia, and as it has been shown reduce bone pain, improve quality of life, delay skeletal events and reduce their number in patients with multiple myeloma and other cancer forms.

Data on a cardiorespiratory system are some kind of integrated indicator of a condition of an organism. Heart rate is closely connected with complex physiological changes which happen in response to regular physical exercises. In this regard we studied the working capacity of athletes in vitro by using indicators of energy consumption, the efficiency coefficient, oxygen consumption and work of a cardiovascular system during loading and during restoration. Authors suggest that if work of identical intensity is set to athletes, its duration will be objective criterion of endurance.

Authors have studied graphic trajectories of speed of barbell movement when performing squat with a bar in powerlifting without burdening and with burdenings of 50%, 60%, 70%, 80%, and 90%. It has been established that the form of a graphic trajectory of speed of bar movement at squat without burdening (with a barbell) and also when overcoming 50% of burdening represents the sinusoid which is characterized by manifestation of two extrema. The first (negative) extremum characterizes the speed of bar lowering, and the second (positive) – speed of bar lifting. Change of a form of a sinusoid of speed of bar movement happens at increase in burdening of more than 60%. This is demonstrated in emergence of two extrema on a sinusoid of speed of raising between which the period of decrease in speed up to a movement stop when burdening is 90% and above is shown. The obtained data make it possible to allo-cate two types of dynamics of speed of bar movement: continuous and discrete.

The fauna of ixodic ticks in the foothill zone of the Republic of North Ossetia-Alania is represented by 3 species: Dermacentor marginatus, Ixodes ricinus, and Boophilus annulatus, the quantitative composition and activity of which depend on the season of the year. The material was collected from cattle. By using an example of the species of B. annulatus dominant for this zone, the dependence has been revealed of the fertility of Ixodes ticks on environ-mental and biological factors. On the average, the cycle duration in the spring period was 12 days, with fecundity of up to 1737,35 eggs/individual. In the autumn period, the duration of the gonadotrophic cycle of B. annulatus is on the average 14 days, but with a lower fecundity – 782,6 eggs/individual. Thus, the fecundity of B. annulatus in the foothill zone in spring is 2,2 times higher than that in the autumn period.

Quite often, experts in the field of information security and information protection in their work are faced with the need to generate random sequences and numbers. Most often, random numbers are required in problems of modeling, numerical analysis and testing, but there are many other very specific tasks. It is known that in all modern programming languages there is a function random or its analogs. These functions most often give really good pseudo-random numbers. This article discusses the features of the implementation of a linear congruent method, which is most often used in the random function, and a method for obtaining random numbers using a polynomial counter, which is often used to test hardware.

To create corporate information systems, we use at present the Oracle database management systems (DBMS), which are characterized by high productivity, reliability and resiliency and occupy a leading position in the market of DBMS. With increasing number of users and volume of data, the probability of performance degradation of the database (DB) invariably increases. Often it is difficult to detect the reason of slow work of system. Therefore, a significant portion of administrator time is spent for monitoring databases and identifying problems, their reasons and finding solutions before these problems become noticeable to users. The main purpose of tuning is to achieve adequate response time of the system without reducing performance of other users or applications. Thus, in order to ensure high productivity of users and application, the database needs to be under constant surveillance. Oracle has a large arsenal of tools to alert the database administrator of emerging problems. This article discusses the monitoring tools of the Oracle DBMS. Such diagnostics is in the ability to identify the causes of dysfunction, and to provide a high DB performance.

To solve practical problems, it is necessary to carry out a special preliminary data transformation for their successful assimilation with the help of Kalman filtering and further forecasting the dynamics of changes in the production system. Methods of preliminary data processing are suggested: coding of input and output data streams, data normalization, data preprocessing: removal of obvious systematic errors, jumps and regularities. The general principle of preliminary data processing, both for inputs and outputs, is maximization of entropy. The series of data obtained during the monitoring of production have a significant specificity. They can contain complex irregular variations and nonstationary effects of various kinds. To ensure the required accuracy and consistency of data on the production process, it is necessary to integrate various formats of data representations and to avoid their duplication. Data cleaning is a special mechanism for detecting and removing explicit errors and other inconsistencies in the input data. Filters for data assimilation work only with numerical data, which indicates the need for coding input and output data. In order for the assimilation filter to treat input and output values uniformly, all quantities must be normalized. The data obtained as a result of preliminary processing allows increasing the accuracy and reliability of the work of the time series forecasting module by optimizing the configuration of the filter operation and the parameters of the production system model.

This article discusses modern tools for analyzing and processing textual information. A method is proposed for automatically comparing documents of various dimensions for the authenticity of information presented in one of them with respect to the second one, which, in turn, is a proven source for a given subject area. And also describes the best way to select the desired source for the question, the answer to which is the text to be checked. The technique is based on a comparison of knowledge graphs derived from the “relationships” of keywords with other elements of the text. In addition, adapted models for obtaining vector representations of documents in a multidimensional space, taking into account the semantics and context in which they are used. The proposed approach provides for a pre-formed database with sources (theoretical materials of the subject area) and a question-answer module (which will be checked for authenticity).
