As a result, we obtained a comparative analysis of methods for determining the type of defects on digital X-ray images. Scope - determination of the type of defects on digital X-ray image

Professional burnout as a form of alienation

Актуальность. Одной из социальных ценностей, постулируемых современным обществом, является благосостояние людей в самом широком контексте понимания. Мы связываем благо- состояние людей с социокультурными возможностями для развития и реализации потребностей и интересов человека в социальном, психологическом, эмоциональном и физической плане. При этом реальность характеризуется как «лоскутная», динамичная, соединяющая различные взгляды и трансформирующиеся установки. Человек становится уязвимым, не имеет возможности фундаментального самоопределения и стабильного существования в современном мире. Именно поэтому человек в процессе самоосмысления отчуждается от неопределенного внешнего мира и неопределенного себя. В результате в «лоскутной» реальности возникают новые формы явлений, такие как, например, профессиональное выгорание. Цель: рассмотреть профессиональное выгорание как форму отчуждения от современной «лоскутной» реальности. Метод: культурфилософский подход к исследованию проблемы отчуждения. Выводы. Профессиональное выгорание как форма отчуждения является результатом «лоскутной» реальности и проявляется на трех уровнях человеческого существования: внутренний мир, внешний мир, профессиональные качества.Relevance. One of the social values posited by modern society is the well-being of people in the widest context of understanding. We link the well-being of people with sociocultural opportunities for development and realization of the needs and interests of people in social, psychological, emotional and physical terms. At the same time, reality is characterized as «patchwork», dynamic, connecting different views and transforming installations. A person becomes vulnerable, has no possibility of fundamental self-determination and stable existence in the modern world. That is why a person, in the process of self-understanding, is alienated from an indefinite external world and an indefinite himself. As a result, new forms of phenomena, such as professional burnout, arise in the «scrappy» reality. The aim of the study is to consider professional burnout as a form of alienation of modern «patchwork» reality. Method: cultural philosophical approach to the study of the alienation problem. Conclusions. Professional burnout as a form of alienation is the result of «patchwork» reality; it manifests itself on three levels of human existence: the inner world, the outer world, professional qualities

Synergism of microwaves and ultrasound for advanced biorefineries

AbstractConventional energy sources are limited and non-renewable and their consumption contributes to greenhouse gas emissions. The world is in need of advanced biorefineries to meet ever growing energy demands associated with population growth and economic development. An advanced biorefinery should use renewable and sustainable (both in quality and quantity) feedstock that gives rise to higher energy gains with minimum non-renewable energy and resource consumption. Development of advanced biorefineries is currently encircled by two major issues. The first issue is to ensure adequate biofuel feedstock supplies while the second issue is to develop resource-efficient technologies for the feedstock conversion to maximize energy and economic and environmental benefits. While microalgae, microbial derived oils, and agricultural biomass and other energy crops show great potential for meeting current energy demands in a sustainable manner, process intensification and associated synergism can improve the resource utilization efficiency. Synergism of process intensification tools is important to increase energy efficiency, reduce chemical utilization and associated environmental impacts, and finally process economics. Among the many process intensification methods, this commentary provides a perspective on the essential role of MWs and US and their synergy in biofuel production. Individual, sequential, and simultaneous applications of MWs and US irradiations can be utilized for process intensification of various biofuels production and selective recovery of high value bioproducts. Process related barriers, namely mass and heat transfer limitations, can be eliminated by this synergism while improving the reaction efficiency and overall process economics significantly. In this article, a brief review focused on recent developments in MW and US mediated process intensification for biofuel synthesis and associated issues in their synergism followed by a discussion on current challenges and future prospective is presented

Analysis of the construction of the hightemperature gas infrared radiator with the use of virtual prototyping

Method of virtual prototyping with the following mathematical modeling was used to simulate the heat-mass exchange and combustion during the operation of high-temperature gas infrared radiators, and to find optimal technical solutions for its design. The most authoritative and approved software product Ansys Multiphysics was used. The results of the mathematical modeling of heat and mass transfer in a turbulent reaction medium with combustion reproduce the experimental data produced by a measurement in real operating conditions of the gas-fired infrared heat emitter. The temperature distribution along the height of the ceramic nozzle was established. Obtained results enable estimation of the ignition and combustion zones
