ПРИМЕНЕНИЕ ИМИТАТОРА БИОЛОГИЧЕСКИХ ТКАНЕЙ ДЛЯ ДИАГНОСТИКИ СКВОЗНЫХ ОГНЕСТРЕЛЬНЫХ РАНЕНИЙ, ПРИЧИНЕННЫХ ПУЛЯМИ КАЛИБРА 5,45 мм

The study and diagnosis of perforating gunshot wounds, especially those that are caused by 5.45 mm caliber bullets are connected with certain difficulties due to the instable behavior of these bullets in biological tissues (viscoelastic environment). With regard to that and based on the natural tests with the help of ballistic plasticine, the article establishes the peculiarities of perforating gunshot injuries caused by the abovementioned bullets. The natural tests also allowed to determine the influence of the changes made in the bullet structure in order to increase its expansion properties. In addition, the experiments determined the amount of kinetic energy of 5.45 mm bullets in order to perforate a block of ballistic plasticine of the respective width, it allowed to determine the resistance coefficient of the viscoelastic environment with regard to the unstable behavior of the bullet inside the obstacle. The article suggests a method to determine the speed of the bullet after it leaves the obstacle in the form of a simulator of biological tissues, it allows to determine the ballistic properties of 5.45 mm bullets before and after its contact with the obstacle.На основі результатів натурних випробувань за допомогою балістичного пластиліну встановлено особливості наскрізних вогнепальних пошкоджень, заподіяних кулями калібру 5,45 мм. Експериментально визначені витрати кінетичної енергії зазначених куль, необхідні для повного пробиття блоку певної товщини з урахуванням їх нестабільної поведінки в товщі перешкоди. Запропоновано розрахунковий метод визначення швидкості куль після подолання перешкоди у вигляді імітатора біологічних тканин

Methodology of calculation of construction and hydrodynamic parameters of a foam layer apparatus for mass-transfer processes

Промислова реалізація методу стабілізації газорідинного шару дозволяє значно розширити галузь застосування пінних апаратів і відкриває нові можливості інтенсифікації технологічних процесів з одночасним створенням маловідходних технологій. У статті встановлені основні параметри, що впливають на гідродинаміку пінних апаратів, розглянуті основні конструкції та режими роботи пінних апаратів. Виявлено зв'язок гідродинамічних параметрів. Розглянуто гідродинамічні закономірності пінного шару. Вказані фактори, що впливають на процес масообміну, як в газовій, так і в рідкій фазах. Проведений аналіз ряду досліджень показав, що перспективним напрямком інтенсифікації процесу масообміну є розробка апаратів з трифазним псевдозрідженим шаром зрошуваної насадки складних форм із сітчастих матеріалів. Отже, необхідне проведення спеціальних досліджень гідродинамічних режимів роботи апарату з сітчастою насадкою і визначенням параметрів, що впливають на швидкість переходу насадки з одного режиму в інший.Industrial implementation of the stabilization method of the gas-liquid layer can significantly expand the field of use of foaming apparatus and opens up new opportunities for intensifying technological processes with the simultaneous creation of low-waste technologies. The article establishes the basic parameters influencing the hydrodynamics of foam apparatus, considers the basic constructions and operating modes of foam apparatus. The connection of hydrodynamic parameters is revealed. The hydrodynamic laws of the foam layer are considered. The indicated factors affecting the process of mass transfer, both in the gas and in the liquid phases. The conducted analysis of a number of studies showed that the perspective direction of intensification of the mass transfer process is the development of apparatuses with a three-phase fluidized bed of an irrigated nozzle of complex forms with mesh materials

Lev Evgenevich Shaposhnikov in the context of russian philosophy

Introduction: the present paper aims to portray Lev Shaposhnikov, a Russian scholar, professor, doctor of philosophy as an advocator of the historico-philosophical approach. For this purpose it is essential to provide a holistic analysis of the personality of L. Shaposhnikov as well as his philosophical views in the synchronic and diachronic dimensions.   Materials and Methods: Lev Shaposhnikov’s research papers devoted to the problems of the Russian religious philosophy as well as works of prominent Russian scholars of the XIX-XX centuries served as materials for the given study. The research methods employed included philosophical analysis, interpretation, comparison and generalization. Results: as a result of the conducted research L. Shaposhnikov’ philosophical standpoint has been analysed, including description and evaluation of his academic, scholarly, and managerial activity in the philosophical realm. Overall, it is clear that Prof. Shaposhnikov’s research is centred around a range of topics, such as: history of the religious philosophy and Orthodox theology; development and specific features of spiritual education in Russia. At present this thematic field is being widened due to investigations of philosophical and pedagogical views of Russian scholars of the ХIХ-ХХ centuries. Lev Shaposhnikov's achievements concern not only profound academic enquiry, but also creation of a school of thought on the history of philosophy, involvement in educational activity, organization of large academic events (for example, Rozhdestvenskiye chteniya – an international conference held in Nizhny Novgorod for 30 years), participation in collective research of scholars from Russian leading universities (such as the Moscow State University and others).  Discussion and Conclusion: within the framework of the present paper a scholarly discussion of famous philosophers from Russia (Moscow, St. Petersburg, Nizhny Novgorod) and Belorussia addressed to Prof. Shaposhnikov is presented. It helps comprehend his key ideas in their relation to the modern scientific context and the works of known Russian philosophers of the XIX-XX centuries.Analysis of the historiosophy of Russian philosophers (such as V. Rosanov, N. Berdyaev, and others) is one of the foci in L. Shaposhnikov’s works. The author often uses an innovative approach to interpret the history of philosophy, yet his logic and vision provide reliability of the results obtained. Moreover, investigation of the Russian religious philosophy, in-depth analysis of the ideas of conservatism, research into the history of spiritual education in Russia represent important directions in L. Shaposhnikov’s scholarly work . An obvious asset of L. Shaposhnikov’s works is systematization and classification of the philosophical issues as well as enriching the terminology base of philosophy. Thus it could be posited that research studies by L. Shaposhnikov are sure to have a valuable methodological potential.In general, the authors of the given paper managed to portray Lev Shaposhnikov as a prominent modern scholar and reveal the role of his views in the history of the Russian philosophy

Language Training is A Necessary Component of A Doctor's Professional Competence (to the Anniversary of the Language Training Department)

One of the most important conditions for training a specialist in any field of work is his/her language training, the level of which largely determines the quality of education and the effectiveness of further professional activity. Knowledge of professional terminology allows you to successfully master educational subjects, knowledge of a foreign language expands access to information resources, which contributes to the professional growth of the specialist. The Dnepropetrovsk Medical Academy has always paid great attention to the formation of language competence of students. This year, the language training department celebrates its 90th anniversary, and this article outlines the history of the department, the main areas of work, successes and achievements, goals and future prospects, presents a talented team of teachers-philologists, changing over time, but always remaining purposeful, creative and inspired
