Background: Gangue is the concomitant product of coal mining. The traditional approach for gangue treatment is to transport it from underground to ground level to accumulate and form gangue hills. Objective: On the basis of summarizing previous research results, this paper introduces the hydraulic roller crusher and the electric machine built-in coal gangue roller crusher, which avoids the complex transmission problems caused by the movement of the central axis when the roller crusher is allowed to roll. Methods: The hydraulic counter-roll crusher directly separates large pieces of coal and underground gangue such that large pieces of coal gangue do not escape from the well. The electric machine built-in roller crusher is an explosion-proof electric machine used in the crushing roller. Results: Both of these crushers can be used in the selective crushing technology of coal gangue in a coal mine and can meet the requirements of crushing different material sizes and generally avoid the centre of the roller crusher. Conclusion: Both of these crushers reduce transportation costs, minimise land occupation, prevent surface subsidence, decrease environmental treatment costs, reduce environmental pollution, and decrease the transport volume of gangue underground. Various patents have been discussed in this article.

Background: Suicide prevention is a major challenge for penal institutions in many countries. The traditional approach relies on the expertise of health professionals and is supplemented by the intervention of other professionals and the inmates themselves. New methods of suicide prevention based on peer support have been developed in recent years. Peer prevention programs rely on the ability of inmates to identify suicide risk. Aims: This study examines perceived suicide risk among inmates and explores possible explanations. Method: 54 inmates and 17 professionals working in prisons responded to a questionnaire. Results: The peer prevention program was found to change inmates’ expectations of support in the event of a suicide crisis. The study also found that the inmates involved in the program tended to underestimate the risk of suicide. The perception of the prevention program and the level of self-consciousness were found to account for the underestimation of suicide risk. Conclusions: Support for inmates involved in suicide prevention programs must take into account their isolation in prison. The training provided to inmates must also consider the biases affecting the assessment of risk.

Informatization of education has been going on for 30 years. During this time, a good material and technical base appeared in schools, there are repositories of e-learning resources to which teachers have access. However, it is difficult to use these e-learning resources due to their too large number and not always high level. It is advisable to introduce a system of reviews and recommendations, to conduct a comparative analysis, as well as to make reviews of resources on a particular subject/topic. In addition, the demand for e-learning resources is affected by the fact that education authorities encourage not so much the use of e-learning resources as their development by the teacher himself. In general, the load on teachers has increased instead of the promised saving of time and effort when using the e-learning resources. At the same time, many e-learning resources are not very effective, since they do not meet the requirements of cognitiveness (they contribute not to learning, but to simple memorization of the material). It is necessary to explore the process of learning new material: this will allow you to create cognitive e-learning resources and other resources that would help you with equal probability to successfully acquire new knowledge for students belonging to different psycho-types. At the initial stage of the study of any subject, it is more expedient to use the usual “paper” method, that is, a textbook and not overload the student’s brain with excessive information. Only when he has mastered the basic provisions, we can turn to e-learning resources, bearing in mind that they must be cognitive, that is, they are aimed at logical perception and rapid intuitive learning, only in this case e-learning resources can be considered effective. The conclusion is formulated that cognitiveness is the next stage of informatization of education after the stage of electronization.

If we want securitization to become one of the main channels to attract funding in leasing activity, as the Bank of Russia predicts, one needs to revise some stereotypes. Relying on foreign and domestic research, the author gives a critical assessment of the postulate of the need for uniformity of securitized assets; proves that real estate, contrary to the traditional approach, rather than equipment and transport, prevails in securitization transactions, and explains why this happens. The article presents a new perspective on the behavior of issu- ers concerning the timing of securities circulation; considers feasibility approach to the calculation of variable character of leverage in leasing; explains pro and contra of evaluating the leasing market based on the volume of the portfolio of contracts; reveals the validity of ratings of bonds issued in the course of secu- ritization of leasing assets.

ISBN: 978–9984–742–68–7 The last year saw the appearance of two significant contributions to the study of Latvian dialects. These are the phonology part of the Latvian Dialect Atlas prepared by Alberts Sarkanis (2013) and Latviešu ģeolingvistikas etīdes by Edmunds (Edmundas) Trumpa (2012a). The two are very different in their aims and methods, even though both deal with phonetic isoglosses of traditional rural dialects. In fact, traditional rural dialects are still considered as the only object of research by Latvian dialectologists in spite of the considerable changes to the field elsewhere, marked by the breakdown of the barriers between dialectology and sociolinguistics (see e.g. Chambers & Trudgill 2004 and Auer & Schmidt 2010). However, of the two reviewed books, Trumpa (2012a) seems to be closer to the modern understanding of research into language and space, and therefore his work can be seen as a promise of changes in Latvian dialectology, whereas Sarkanis (2013) almost entirely belongs to the traditional approach. Nevertheless, in the context of Trumpa’s rather innovative book, Sarkanis’ Phonological Atlas serves as a summary of achievements from the previous stage.
