The main scientific and practical calculations used to increase the efficiency of vertical mine workings based on studying the operation of tunneling complexes and road-heading machines, as well as by sectional blasting of the deep wells are presented in the article. This will ensure high-quality mine workings in accordance with the design and improve the operational safety throughout the entire service life. The methods are used related to the complex generalization, analysis and assessment of the practical experience and scientific achievements in the field of the underground geotechnology, theory and practice of explosive destruction of the solid media, mechanics of continuous media, mathematical statistics, as well as studies of the wave processes according to the standard and new methods developed by the leading experts from the leading mining countries of the world, including with the authors participation. Technological audit of the vertical working drilling and blasting was conducted using KPV-4A tunneling complex and the tunneling machine Robbins 73R, as well as the efficiency of conducting them in the cycle of mining operations was established. Mathematical modeling and calculation of the parameters of drilling and blasting operations were carried out using the contour blasting of explosive charges when driving vertical mine workings. Rounder of RS-220 type for the hole boring was recommended (complete with machine tool NKR-100MPА) of the downward wells with a diameter of 220 mm in rocks with a coefficient of f = 8–14 according to the scale of M.M. Protodyakonov, which is already being used at the mines of Ukraine, Russia, the Republic of Kazakhstan, and other countries. The new device for the contactless transmission of electricity from the stationary object to a mobile one was proposed, which will allow to improve the operating conditions of KPV-4A tunneling complex, LMSh-1 mine type elevator used for lifting and lowering people, small equipment, and materials along the rise workings, which is achieved due to external location of the cable rewinding mechanism and the absence of complex, for example, planetary mechanisms. It will also improve the efficiency and safety of work for the vertical mine workings in the rock massifs.

Main Component

High-quality grass feeds (hay, haylage, silage) decrease cost price, improve consumer properties and increase competitiveness of cattle products significantly being the main component of agricultural export for the Republic of Belarus. An important issue of grass feed procurement is acceleration of mowed grass drying process. Reduction of drying time or drying process acceleration has a positive effect on feed quality. To achieve this goal, technique of laying the mowed grass on stubble, in rolls or spreading, turning and conditioning is applied. Based on practical experience of application and analysis, the relevance of repeated rolling (reconditioning) of mowed grasses in rolls is substantiated. Design and workflow of new device for such grass rolling has been developed. Its working unit is designed as a sawn-deck or roller flatting apparatus. The kinematic parameters of the upper and lower rollers have been determined experimentally: the rollers rotation ratio should make 1.01 m ωв / ωн m 1.03. Field tests of the device with legumes helped to determined that it accelerates drying by 15–20%, reduces protein loss by 10–15% compared to drying with no treatment. The presented research materials present the development of the theory of grass feeds procurement mechanization. Use of the materials in practice will improve the quality of grass feeds by accelerating the mowed grass drying process.

<p>In the article recent technologies of formation and development of social and communication skills in children with autism spectrum disorders are analyzed. A systematic review summarizes the most effective and verified interventions of support to socialization of children with ASD: applied behavior analysis (ABA); cognitive-behavioral training (CBT); social stories method; social skills training (SST). We pay special attention to virtual technologies and video simulations so these methods allow to form social skills in children with ASD more efficiently and psychologically safe. Problems and prospects of using virtual technologies for children with ASD needs are discussed.<strong> </strong>The specificity of Russian practical experience and researches in development of heuristic technologies of development of social communication of persons with ASD is described: animal-assisted therapy, somatosensory correction, author art therapy and folk forms of intervention. On the basis of analytical work it is concluded that the gap between theory and practice needs to be neutralized, when scientifically unfounded practical developments are introduced in helping autistic people and researches of scientists are not always verified in an empirical manner.</p>

The comprehensive nature of nurse training needs the involvement of almost all health team personnel, including unit managers to gain practical experience and learn to correlate theory and practice. The overall aim of the study was to explore and describe the experiences of unit managers regarding teaching of student nurses in the clinical area and to develop recommendations that will enhance clinical teaching, for the production of competent future nurse practitioners who will render quality care to patients. A qualitative design, which is explorative, descriptive and contextual in nature, was employed, utilizing a phenomenological approach to capture the experiences of unit managers regarding teaching of student nurses at selected hospitals, where students are allocated for their clinical exposure. Ethical measures as well as measures to ensure trustworthiness were adhered to. In-depth phenomenological interviews were conducted with unit managers who shared their experiences regarding clinical teaching of student nurses. Data analysis was done according to Tesch’s (1990) open coding method. One major theme emerged, namely that unit managers experienced problems when doing clinical teaching of student nurses. Based on the findings the following recommendations were made: Colleges should open a two-way communication with unit managers, involvement of unit managers in the activities that take place at the college like courses, seminars and workshops on clinical teaching, learning contracts should be developed for the students and issues of clinical learning should be addressed and unit managers should be included in both summative and formative evaluations.

In the field of protection and improvement of people?s health, there is a special importance of legally, efficiently, regularly, professionally, and punctually providing medical care, performing other healthcare services, or simply providing medical assistance or care. In this way, an essential social function is achieved, as well as the protection of the constitutionally proclaimed right of physical and mental integrity of the public. However, deterioration of an individual?s health who has been medically assisted is possible in the process of providing medical, or any other assistance in the field of medicine. If it is a gross medical misconduct or any other type of medical misconduct, or gross violation of a profession?s rules, because of which there is a possibility of deterioration of health of one or more individuals, then the crime of medical negligence, for which there are strict statutory offences, applies. This article addresses the aspect of theory and practice about the significance, social jeopardy, and prevalence of this crime, or criminal policy of courts in the Republic of Serbia, alongside many articles in the printed and electronic media which provoke great public attention and rough comments.

The article compares conditions and procedures for the adoption of Constitution and amendments to thecurrent constitution between the Republic of Bulgaria and the Republic of Kazakhstan. The criteria used inthe legal theory for the classification of the constitutions according to the way of their change are used. Bothconstitutions refer to the category of the hard. Bulgaria has a solid core of the constitution, which can onlybe changed by a specially elected institution — a Great (Grand) National Assembly. In Kazakhstan there areeven texts that are not subject to change. The experience of several changes to the two basic laws has beenconsidered. Whit them some of the questions have been answered by juridical theory and practice, whileothers remain open. At the end, conclusions are drawn from the parallel between the changes to the bothconstitutions, some of which are of universal significance.

This article carried out a detailed scientific analysis of the nature and content of operational search tactics. Analysis of the vocabulary literature suggests that, despite minor differences in the interpretation of the concept of tactics, in general, this term means "an integral part of the art of war that combines the theory and practice of preparing and conducting combat." According to the results of the study, it was established that the theoretical basis for the formation of operational-search tactics was the groundwork of forensic scientists. The author's wording of the concept of “operational-search tactics” is provided as a direction of operational-search activity, formed on the basis of its theoretical principles and practical experience of entities carrying out this activity legally with the goal of fulfilling the tasks stipulated by the Law of Ukraine “On operational-search activity” Based on the analysis of the scientific heritage of scientists, it has been established that operational-search tactics in the theory of operational-search activity can be divided into general and special ones.The questions about the delimitation (ratio) of the tactics of secret investigative (search) actions and tactics of operational search activities are considered. Despite some common signs of tactics for conducting secret investigative (search) actions and operational search activities, it should be remembered that investigation tactics are traditionally considered in the framework of criminalistics, but operational search activities are the subject of the study of the theory of operational search activities. At the same time, it was noted that the tactics of secret investigative (investigative) actions, although individual in their sense, should predominantly be based on the provisions of operational investigative activity, and not criminalistics, at least taking into account the fact that the theoretical and practical operational search tactics worked over the years.It is concluded that both forensic and operational search tactics will require a high-quality update. In particular, the results of a survey of investigators and operational workers indicate the need and desirability of borrowing foreign experience in terms of education and training of investigators and operational units on tactics of identifying, preventing and investigating crimes in the field of high technologies (as noted by 81% of respondents).
