Imaging technology is becoming increasingly prevalent in our society.Even though there were many successful imaging modalities ever since the advent of roentgen rays, they all have their shortcomings. And imaging of dental tissue had always been a challenge in imaging science due to the various layers which differ in physical and chemical and structural properties. Considerable improvisations of existing techniques and new research activities.

Nowadays, the Industry 4.0 concept affects every area of the industrial, economic, social and personal sectors. The most significant changings are the automation and the digitalization. This is also true for the material handling processes, where the handling systems use more and more automated machines; planning, operation and optimization of different logistic processes are based on many digital data collected from the material flow process. However, new methods and devices require new solutions which define new research directions. In this paper we describe the state of the art of the material handling researches and draw the role of the UMi-TWINN partner institutes in these fields. As a result of this H2020 EU project, scientific excellence of the University of Miskolc can be increased and new research activities will be started.

The aim of this study was to measure and assess the physical and chemical parameters of water quality in the area of ​​fixnet cage cultureat Lake Tutud Tombatu TigaVillagewhich included temperature, pH, DO, TDS, NO3, NO2, NH3 and PO4 in a different time.This research was conducted from August to November 2016. The research activities consisted of direct measurements in the field (in situ) using a Horiba instrument and laboratory analysis (ex situ) at the Agency for Industrial Research and Development Research Institute of Standardization and Industrial Manado. Determination points were done by purposive sampling which refers to the physiographic location wherever possible in order to represent or describe these waters.Water quality measured at4 stations using a Horiba at a depth of 0.5 meters from the bottom of the lake.Station I represented Inlet water, Station II where the cultivation A, Station III where the cultivation B and Station IVwhere no cultivation. The data obtained and collected were primary data i.e., measurement of physical and chemical parameters of water quality as well as watching for signs of sick fish, dead fish, and the growth of farmed fish.The results showed the water temperature ranged between 28-29 ° C, TDS 0266-0412 mg/L and chemical parameters for dissolved oxygen 2-5 mg/L, pH 7-8 and for the results of laboratory analysis, N03(0.7 - 6.3 mg/L), NO2(0001-0002 mg/L), NH3 (0180-1920 mg/L), PO4(0020-0209 mg/L). In general, the existence of water quality of lake Tutud were still in good condition except for NH3 concentrationthat exceeded quality standard limitsof Government Regulation No. 82 of 2001. Basically lake Tutud can still be used for fish farming, but the addition of new cages were not recommended.   Keywords: Lake Tutud,water quality, physical parameters, chemical parameters, fix net cage

The subject of study in the article is the discourse specifics of representation of economic entities in German newspaper and magazine texts of the last two decades. The purpose of the analysis is to elucidate the factors that stimulate univerbation in connection with the generation and textual integration of co-referential structures different in genesis, structural properties, semantic characteristics and stylistic potential. The study, conducted on the basis of a functional-communicative approach to language, relies on methods and results of studies on text linguistics considering text as a whole structural-semantic unit. Conclusions. 1) Mentioning of a company name is accompanied by integration of the univerb indicating the relevant industry into the text. Along with a two-member chain of co-referential nominations, a three-member chain is also possible (the location of a company is mentioned). 2) Co-referential pairs of the type “company name ‒ collective designation of employees according to headquarters location” (Siemens ‒ Münchener) are characteristic, which demonstrates the lability of univerb toponym semantics. 3) The integration of a proper name into the text requires the usage of characterizing common nouns in order to prepare the reader for the perception of unique names, which is a factor motivating univerbation. 4) Synthetic compounds of the nomina agentis type (Autobauer, Stromversorger) are widely used to describe the kind of activity of an enterprise. In such cases a lexeme with the expected semantics is eliminated (Unternehmen ‘company’, Konzern ‘concern’ etc.). The reduction of the base lexeme of a compound as well as representation of the verb lexeme in the form of nomen agentis has an impact on the semantics and stylistics of the univerb. The results of the study can be used both in research activities on problems of word-formation, semantics and in the training of business translators.

В данной статье проанализировано основное различие понятий учебно-исследовательской и научно-исследовательской деятельности. Основной проблемой является развитие мотивации к учебной научно-исследовательской деятельности учащихся. Выявлено, что на мотивационную готовность студентов к научно-исследовательской деятельности могут оказывать влияние многие факторы, рассмотрено их воздействие. В статье приведены различные студенческие мероприятия, которые могут способствовать повышению мотивации учащихся к исследовательской деятельности. Выявлены, проанализированы научно-исследовательские умения и их компоненты (операционный, содержательный, мотивационный). Реализация в профессиональной подготовке традиционных форм обучения (лекции, лабораторные, практические, семинарские занятия, коллоквиумы, курсовые и дипломные работы, консультации, индивидуальные занятия) помогает овладению учащимися научной информацией, но не всегда способствует формированию необходимых умений и навыков. Очевидно, что внедрение новых теоретических обобщений в учебный процесс (чтение преподавателями проблемных лекций, введение новых теоретических разделов по наиболее актуальным проблемам современной науки, расширение перечня учебной литературы и интернет-источников, освоение новых методик исследования, подготовка мультимедийных презентаций) повысит интерес студентов к исследовательской деятельности. Образовательный процесс будет проходить более успешно, если в вузе сформирована эффективная образовательная и научно-исследовательская среда, направленная на развитие личности студента. This article analyzes the main difference between the concepts of educational research activity and research activity. The main problem is the development of motivation for educational research activities at students. The authors revealed that many factors can influence students’ motivation readiness for research activities; considered the impact of those factors. The article presents various student activities that can help to increase students’ motivation for research activities; identifies and analyzes the research skills and their components (operational, content, motivation). The implementation of traditional forms of education in professional training (lectures, laboratory, practical, seminars, colloquiums, term papers and theses, consultations, individual classes) helps students master scientific information, but does not always contribute to the formation of the necessary skills. It is obvious that the introduction of new theoretical generalizations in the educational process (delivering of problem lectures, introduction of new theoretical units on the most relevant problems of modern science, expanding the list of educational literature and Internet sources, development of new research methods, multimedia presentations) will increase the interest of students in research activities. The educational process will be more successful if the University has an effective educational and research environment aimed at the development of the student’s personality.

Atherogenesis has been well demonstrated to proceed in an ordinal fashion. Imaging technologies have advanced substantially in recent decades, enabling early detection of atherosclerosis. Some modalities, such as coronary CT, have seen broad clinical adaptation. In contrast, others, such as flow-mediated dilatation, remain predominantly research-based. Optimal and appropriate usage of these technologies remains an area of active investigation. We hypothesise that investigators ought to consider which stage of atherosclerosis is under investigation when choosing imaging modalities. Additionally, when assessing the efficacy of a particular treatment, some imaging modalities may be more appropriate than others. We review the most important available imaging modalities and suggest stages at which each may or may not be well used. Conceptual application of the classic stages of atherosclerosis model to the variety of modern imaging modalities available will result in more effective investigation and treatment of cardiovascular disease.

The article elaborates on the topic about abrupt catagenetical alterations in sedimentary rocks and postulates the topicality and problematics of the study during exploration of new and already existing oil and gas deposits. The goal of the research is the identification of compacted zone which was formed under secondary physical and chemical processes within 110–120 temperature interval (including possible paleotemperature effect). To get the most qualitative/comprehensive results, integrated analysis of lithology, petrophysical characteristics of cored intervals in the slide sections and geological information has been done by the authors. Essential part of the article is devoted to the methodology, study description and interpretation of outcome results. Four gas condensate fields were chosen based on their similarity. They have similar tectonic, structural, generation and accumulation conditions and all of them are located in the axial and pre-axial zone of the central part of Dnieper-Donets basin. After well log data processing and precise microscopy study of slide sections, the authors concluded that 110–120 temperature surfaces, which frame compacted and altered zone (identified by the Ukrainian Research Institute of Gas), have to be shifted according to new research findings. Practical value of this work is to identify compacted and decompacted zones at a great depth, which can be an indirect indicator of traps existence for hydrocarbons and possible manifestations of abnormal pressures.

This article attempts to reveal, based on archival materials, the main directions of research activities of the outstanding scientist A. N. Frumkin (1895-1976) during His work at the L. ya.Karpov research Institute. It was at this time, from 1992 to 1946, that A. N. Frumkin worked his way up from the head of the Department of surface phenomena to the Deputy Director of the Institute for scientific work. The main directions of his research interests in the field of physical chemistry are shown. He paid special attention to the study of the surface properties of metals. In the circle of his interests included the study of adsorption phenomena. The "Frumkin isotherm" was developed, and the fundamental position about the zero charge potential was proved. A. N. Frumkin has repeatedly made scientific reports in leading scientific institutions in Germany, the USA, the Netherlands, and others. A. N. Frumkin's contribution to the development of electrochemistry, which is of great importance for both science and practice, was appreciated. His scientific work was highly appreciated by the government. Thus, it was during the "Karpov period" of A. N. Frumkin's scientific activity that the most important fundamental research was carried out, which for many years determined the directions of development of physical and chemical science, and an authoritative scientific school of electrochemistry was formed.

Background The project “Precision Health and Everyday Democracy” (PHED) is a transdisciplinary partnership that combines a diverse range of perspectives necessary for understanding the increasingly complex societal role played by modern health care and medical research. The term “precision health” is being increasingly used to express the need for greater awareness of environmental and genomic characteristics that may lead to divergent health outcomes between different groups within a population. Enhancing awareness of diversity has parallels with calls for “health democracy” and greater patient-public participation within health care and medical research. Approaching health care in this way goes beyond a narrow focus on the societal determinants of health, since it requires considering health as a deliberative space, which occurs often at the banal or everyday level. As an initial empirical focus, PHED is directed toward the health needs of marginalized migrants (including refugees and asylum seekers, as well as migrants with temporary residency, often involving a legally or economically precarious situation) as vulnerable groups that are often overlooked by health care. Developing new transdisciplinary knowledge on these groups provides the potential to enhance their wellbeing and benefit the wider society through challenging the exclusions of these groups that create pockets of extreme ill-health, which, as we see with COVID-19, should be better understood as “acts of self-harm” for the wider negative impact on humanity. Objective We aim to establish and identify precision health strategies, as well as promote equal access to quality health care, drawing upon knowledge gained from studying the health care of marginalized migrants. Methods The project is based in Sweden at Malmö and Lund Universities. At the outset, the network activities do not require ethical approval where they will not involve data collection, since the purpose of PHED is to strengthen international research contacts, establish new research within precision strategies, and construct educational research activities for junior colleagues within academia. However, whenever new research is funded and started, ethical approval for that specific data collection will be sought. Results The PHED project has been funded from January 1, 2019. Results of the transdisciplinary collaboration will be disseminated via a series of international conferences, workshops, and web-based materials. To ensure the network project advances toward applied research, a major goal of dissemination is to produce tools for applied research, including information to enhance health accessibility for vulnerable communities, such as marginalized migrant populations in Sweden. Conclusions There is a need to identify tools to enable the prevention and treatment of a wide spectrum of health-related outcomes and their link to social as well as environmental issues. There is also a need to identify and investigate barriers to precision health based on democratic principles. International Registered Report Identifier (IRRID) DERR1-10.2196/17324
