Abstract:

Irish mechanics' institutes have received little attention from historians of science, but their history presents intriguing questions. Whereas industrialization, Protestant dissent and the politics of liberal social reformers have been identified as crucial for the development of mechanics' institutes in Britain, their influence in Ireland was regionally limited. Nonetheless, many unindustrialized, provincial, largely Catholic Irish towns had mechanics' institutes in the first half of the nineteenth century. This paper investigates the history of the two mechanics' institutes of Galway, founded in 1826 and 1840, and analyses how local and national contexts affected the establishment, function and development of a provincial Irish mechanics' institute. Situating these institutes within the changing social and political constellations of early and mid-nineteenth-century Ireland, it shows how Catholic emancipation, the temperance movement and different strands of Irish nationalism affected approaches to the uses of science and science education in Ireland.

Abstract:

In the 1950s - 1970s, the most important organizational form of higher education science was research institutes attached to higher education institutions. Having appeared in the 1920s, it proved effective. The first thematic laboratories were organized in Leningrad in 1956 at the Polytechnic Institute by Professor B.P. Konstantinov (who later became an academician) and the Electrotechnical Institute named after V.I. Ulyanov (Lenin) by Professor N.P. Bogoroditsky. The desire of scientists to increase efficiency of the research, to bring it closer to the practical needs of the national economy reflected in the organization of 13 research institutes at the Polytechnic Institute in 1963. In the 1950s - 1960s, the Leningrad State University had the previously formed research institutes: the Institute of Mathematics and Mechanics, Physical, Chemical, Biological and Physiological institutes, the Institute of the Earth’s Crust, the Geographical and Economic Institute. In 1959 – 1965, the University’s scientists completed the research on 5,300 planned topics. They performed 3,017 separate experimental and theoretical research, prepared 785 textbooks and teaching aids, completed 543 dissertations, and conducted contractual work on 955 topics. Only in 1969, 3,500 research papers created by LSU scientists were published. Among them were 107 monographs and 74 textbooks. Creative collaboration with industry workers was an integral part of the activities of the Leningrad State University’s scientists. Many of the LSU collective’s research were directly related to production needs. In 1959, the collective of the Physical faculty concluded 32 contractual works and 19 agreements on creative cooperation with industrial enterprises. In 1963, they performed research on 60 contractual topics for a total of 1,100,000 rubles, at the same time conducting 22 topics, provided by the agreements on the creative cooperation for a total amount of 1,300,000 rubles.

Abstract:

This study aimed to explore a methodology for the professional teaching of students of technological institutes (whether it is middle and/or higher level) in inverted classrooms. It is based on the alternative and interactive method of content appropriation based on projects, which integrate the face-to-face modality with the virtual modality. The scientific novelty lies in the establishment of a dynamic that integrates the face-to-face modality with the virtual modality, based on the link between academic, labor, and research. Document review methods, the system approach, direct observation in the field, the pedagogical pre-experiment, and the Chi-square statistical test (X2) are used. As a result, the favorable impacts on the development of professional skills were observed in a sample of 100 students of the Mechanics career at the University of Holguín, Cuba, with the application of the result. It can be generalized in any worker training center with flexibility and adaptability to the characteristics of these entities.

Abstract:

In the short historical essay, the ways of formation of Materials Science in Ukraine are considered, and tendencies of its development over the World were taken into account. The outstanding human resources and excellent raw deposit capabilities of Ukraine have led to creating Ukrainian scientific schools back in the days of the Russian Empire, which were comparable to the Ural and another world schools of metallurgists and metal scientists. The further development of science on materials in Ukraine is closely related with establishing the Academy of Sciences in 1918. From the first twelve members of the All-Ukrainian Academy of Sciences, three of them namely V.I. Vernadsky, P.A. Tutkovsky and S.P. Tymoshenko, had represented the natural sciences. The election of E.O. Paton to the Academy in 1929 for "technical sciences" specialty had initiated the usage of promising achievements of fundamental sciences for development of applied ones. Since that, the famous Institutes of Ferrous Metallurgy (1936), Metal Ceramics and Special Alloys (1955) and others were founded. The idea to develop the new area of knowledge, which would combine the different types of interatomic bonding to be resulted in new materials and would not be preferable to metallic materials only, has been already in time, namely in 1963. B.Ye. Paton jointly with I.M. Frantcevych had created the Department of Physical and Technical Problems of Materials Science, which included a few institutes namely: electric welding (Paton Welding Institute, PWI), cermets and special alloys (Institute for Problems of Materials Science (IPMS since 1964), foundry (problems of casting since 1964, and Institute of Physics and Technology Metals and Alloys (PTIMA since 1996), mechanical engineering and automation (Institute of Physics and Mechanics (IPM since 1964). And although the institutions are quite different in their profiles, their uniting direction is materials science. As early as 1963, V.N. Yeremenko was elected as the first academician for the "materials science” specialty. Therefore, the issue of a new collection of scientific papers under the title "Progress in Materials Science" is natural and vitally required. It is corresponding to global trends in the formation of scientific and technical priorities in developed countries and is as the task for Ukraine too.

Visiting seafarers spent time in the ins titute’s library, leaving behind crafts or souvenirs picked up in exotic ports of call as a token of thanks. In the 1930s, honorary curator Vernon Smith refi ned the collection to focus solely on nautical material and searched for artifacts to enhance it. Th e collection now comprises over twenty thousand objects.

Abstract:

Magnetic pulse forming is based on the principle of generation of a repulsive force called, Lorentz force due to opposing magnetic fields of adjacent conductors. Magnetic pulse forming of light weight materials such as aluminum, magnesium has been studied by many universities, institutes due to its advantages. But magnetic pulse forming is a complicated research area involving different topics in electromagnetic mechanics, plastic working, and materials mechanics. Therefore, development of FE-model of magnetic pulse forming process is a useful approach for better insight into workpiece deformation mechanics with electromagnetic interaction and further provides design and quality control information. To successfully accomplish this objective, a 3-dimensional ax-symmetric electromagnetic numerical model has been developed. The equation was solved using a general mechanics computer program, ANSYS EMAG and LS-DYNA code.

Abstract:

From the late eighteenth century onwards, urban life underwent increasingly rapid change as towns outgrew their limits, industries polluted their skies and rivers, and a host of new types of building appeared to cater for new needs and activities. Not only did towns look different, but, as Thomas Markus has said, ‘they also ‘felt’ different in the organization of the spaces they contained.’ Buildings which housed scientific activities—the learned societies, literary and philosophical societies, professional institutes, mechanics institutes, and by the end of the century the new civic universities—were one manifestation of this different ‘feeling’. These were quite new types of building, and we should therefore expect them to give us valuable information about the development of science, about ‘images’ of science and the meaning of those images, as well as the actual practice of science.

Abstract:

Technical Mechanics being a complex of fundamental general technical disciplines is the theoretical and scientific basis for the study and development of modern engineering. Using its laws and principles buildings, constructions, machines and equipment can be developed and researched. However, Technical Mechanics is the most difficult discipline to learn. The main difficulties of this course are based not only on the application of the principles of theoretical mechanics to complex mechanisms of different types but also the course stands out with its specific and particular features and also based on previously unknown terminology for students as well as is an introduction to the Mechanics of Machines in general. Difficulties in the acquisition of learning content are also caused by time constraints devoted to the study of this subject in higher technical educational institutions. Consequently, teaching Mechanical Engineering in today's context requires a widespread involvement of computer technologies into educational processes that meets the requirements of intensification of students’ individual study and diversifies forms and means of learning, motivates students and optimizes their learning process. The problem of the research is to identify the possibilities of intensifying the process of teaching Technical Mechanics which is a fundamental discipline for other special courses in Technical Institutes using computer training software GIM. The article justifies the feasibility of using GIM software during Technical Mechanics course by students of engineering and technical higher education institutions. GIM software is used during practical classes to support and supplement theoretical lectures; GIM functions as an educational supplementary tool to enhance students' knowledge. Training of first and second year students of general engineering disciplines based on GIM computer training program enhances the professional culture of the future specialist, stimulating his need for continuous self-improvement. New educational technologies are an effective method of teaching students and help better understanding of the subject, promotion and spreading of scientific knowledge

This paper analyses the historical accuracy of a statement made in Justinian's Institutes about the development of the late-antique tripartite will, and finds that the enactments of emperors are given too much credit, and the practice of men too little. The paper follows the chronologically uneven and geographically disparate ways in which writing came to be used in wills, and notes the ways in which the problems writing could pose were systematically ignored by imperial enactments until very late.

Abstract:

This article brings to the fore the work of the Public Pedagogies Institute, a not-for-profit organisation, as an enactment of the public realm. This Institute stands within a lineage of education beyond formal sites of learning such as the Raphael Samuel History Centre and, prior to this, Mechanics Institutes. In each of these instances these educational sites either challenge or depart entirely from knowledge generated in authorised or elite institutions. The continuation of instances where education can occur beyond sites of formal education is becoming increasingly critical in a challenge to what and whose knowledge is considered of value. One of the central questions this article attends to is how knowledge that circulates outside of the academy, such as that which occurs within the Public Pedagogies Institute, can be recognised. An analysis of the Institute as a site for knowledge formation is undertaken through the ideas of Hannah Arendt, specifically her concept of the public realm, to critically examine the possibilities for knowledge. For Arendt, her concept of the public realm is a space where the revelation of who we are engenders the possibility of new beginnings. The significance of undertaking such an analysis through the work of Arendt is to foreground how iterations of the public can be recognised as sites of education.

Abstract:

The work is devoted to earthquake forecasting. The physics of an earthquake, despite the fact that this problem has been facing humanity for more than 100 years, it still remains unclear. What is the reason and why this is a very important problem, which is being solved by a huge number of universities, institutes and companies around the world. The physical model of a tectonic earthquake is presented in the form of a plate connection loaded with a shear force, in which the non-displacement is provided by friction forces. In calculating the contact interaction, the pliability of the plates and the tangential pliability of the contact layer are taken into account. A system of equations has been obtained, the solution of which makes it possible to specify to some extent the location, strength and time of the earthquake occurrence.

Abstract:

In the context of the great challenges of our time, scientific heritage has an urgent and resource value for the development of science, taking into account the public needs for its socio-cultural communication and personalization. The historical experience of the organization and management of science through the prism of the activities of outstanding scientists of Russia – the founders of academic institutions at the Novosibirsk Scientific Center (NSC) of the USSR Academy of Sciences in the late 1950s. Its results and prospects are summarized in the monograph N. Kuperstokh, I. Kraineva “The institutes of the Novosibirsk Scientific Centerare named after them”. Using the example of 14 named institutes, the authors analyzed the role of leading scientists in the formation of new scientific directions for Siberia in the fields of mathematics, computer science, mechanics and energy, physics, chemistry, biology, geology. The book reveals the specifics of the organization of research in each field of knowledge. The naming of the first directors to the institutes of the NSC testifies to their expedient time and perspective vision of scientific directions, which in the XXI century are implemented by their students and followers. A new approach to the study in historical dynamics of the role and influence of the scientific heritage of leaders in the context of socio–cultural space shouldbe developed in relation to other scientific centers of Siberia – Tomsk, Krasnoyarsk, Irkutsk, Yakutsk, adapted to the project “Akademgorodok 2.0”.

Abstract:

The history of the creation of the first Soviet universal electronic computers is an excellent example of the ability and readiness of the Academy of Sciences to be a leader in the creation and development of new areas of science and technology. All work, starting with the design of computers and ending with the stage of creating computers and software, was carried out at the institutes of the Academy of Sciences. On December 4, 1948, I.S. Brook and B.I. Rameev received a copyright certificate for the invention of an automatic digital machine. It was the first official document indicating the beginning of work on the creation of computers in the USSR. The first Soviet computer, the M-1, was created at the Power Energy Institute under the leadership of Corresponding Member I.S. Brook. At the Institute of Precise Mechanics and Computer Engineering, under the guidance of Academician S.A. Lebedev, the most successful series of Soviet computers, BESM, was produced. The first copies of all new models of computers before being launched into a series were subjected to comprehensive tests at the Institute of Applied Mathematics, whose director was Academician M.V. Keldysh. Academician S.L. Sobolev was the ancestor of the Russian school of programming. The article contains little-known information about the first steps of computer science in Russia. Some facts about the history of those years were hidden in the archives for a long time and are now published for the first time.

Abstract:

The study aimed to evaluate the extent of occupation-related injuries and accidents, the use of Personal Protective Equipment (PPE), Occupational Health and Safety (OHS) training, and awareness and implementation of OHS policy among Technical Training Institutes (TTIs). The study used qualitative and quantitative methods to analyze data from 99 final-year trainees, including 47 auto mechanics, 24 electricians, 16 welders, and six OHS focal persons. Data was collected through self-administered questionnaires and in-depth interviews and analyzed using SPSS-16 and MAXQDA-2020. The study revealed a commendably low rate of hazards in training institutes (TTIs), with a mere 10.26% and a mean score of 2.1. This positive outcome, a testament to the high awareness of OHS and PPEs, should give reassurance about the current state of OHS practices in TTIs. The training system was a resounding success, with a mean rating of 4.09 for trainees' understanding and use of PPEs. However, the study also identified areas for improvement, particularly the urgent need for improved monitoring and management support. This need for immediate action is crucial for sustaining and enhancing these standards, and it should make the audience feel the urgency of the situation. [Abstract continued in PDF]

Abstract:

This paper demonstrates sensitive analyses of probabilistic fracture mechanics (PFM) for reactor pressure vessel (RPV) during pressurized thermal shock (PTS) loading, and comparison of our calculation with the results of the international round robin (RR) analyses in Asian countries (Korea, Taiwan and Japan). The international Round Robin activity was performed in PFM sub-committees in the Atomic Energy Research Committee of Japan Welding Engineering Society (JWES) in conjunction with Korea and Taiwan research groups. The purposes of this program are to establish reliable procedures to evaluate fracture probability of reactor pressure vessels during pressurized thermal shock and to maintain the continuous cooperation among Asian institutes in the probabilistic approach to nuclear safety. Some parameters to RPV failure probabilities are chosen to evaluate their significance quantatively. The differences caused by selection of analyzing programs and some input parameters will be discussed.

Abstract:

We propose two stochastic models for the Coronavirus pandemic. The statistical properties of the models, in particular the correlation functions and the probability density functions, were duly computed. Our models take into account the adoption of lockdown measures as well as the crucial role of hospitals and health care institutes. To accomplish this work we adopt a kinetic-type reaction approach where the modelling of the lockdown measures is obtained by introducing a new mathematical basis and the intensity of the stochastic noise is derived by statistical mechanics. We analysed two scenarios: the stochastic SIS-model (Susceptible ⇒ Infectious ⇒ Susceptible) and the stochastic SIS-model integrated with the action of the hospitals; both models take into account the lockdown measures. We show that, for the case of the stochastic SIS-model, once the lockdown measures are removed, the Coronavirus infection will start growing again. However, the combined contributions of lockdown measures with the action of hospitals and health institutes is able to contain and even to dampen the spread of the SARS-CoV-2 epidemic. This result may be used during a period of time when the massive distribution of vaccines in a given population is not yet feasible. We analysed data for USA and France. In the case of USA, we analysed the following situations: USA is subjected to the first wave of infection by Coronavirus and USA is in the second wave of SARS-CoV-2 infection. The agreement between theoretical predictions and real data confirms the validity of our approach.

Abstract:

One of the main and responsible stages of creating an apparatus for numerical analysis of structures using the finite element method is its implementation in the form of a set of programs. The principles of complex construction should take into account modern requirements for strength calculation software in modern calculation complexes. Among them, first of all, automation of the main stages of the computing process, rational use of the resources of the operating and external memory of storage devices, non-closedness in relation to the classes of problems to be solved, algorithms for the task of input data, the method of discretization and solution of systems of equations and etc. In addition, the structure of the programs should take into account the specifics of the semi-analytical method of finite elements, for which such a large experience of creating developed systems of mathematical support for the search of spatial structures has not yet been accumulated, as when using the traditional version of FEM. Considerable experience in solving finite element mechanics problems, accumulated over the past decades, has been reflected in a number of industrial commercial software complexes of domestic (LIRA, SCAD) and foreign (ANSYS, Nastran, ABAQUS) production. The developed finite element base of these software complexes allows you to obtain solutions to a wide range of problems of the mechanics of a deformable rigid body for objects of different dimensions, including for massive spatial bodies, and convenient means of input-output of information and processing of the obtained results make them very accessible to a wide circles of users and allow to display the obtained results with the maximum degree of visibility. There are also object-oriented complexes created at manufacturing enterprises and research institutes, for example at the Institute of Strength Problems of the National Academy of Sciences of Ukraine, at the Dnipropetrovsk National University. The conducted research will determine the most optimal ways of solving the listed problems from the point of view of computing costs and complexity of implementation, as well as outline the circle of unsolved issues.

Abstract:

The publication is dedicated to the contribution of Professor Aleksandr Petrovich Bychkov (1921–2009) to the development of Tomsk State University. Bychkov devoted more than 50 years of his life to Tomsk State University (TSU). As the rector of TSU (1967–1983), he made a significant impact on the improvement of not only TSU, but the entire scientific and educational complex of Tomsk Oblast. As the rector, Bychkov worked a lot and fruitfully on strengthening the material base, raising the scientific and pedagogical level of professors and research workers of faculties and research institutes and, on this basis, the level of training of university specialists. Throughout its history, Tomsk State University has striven for a close combination of training highly qualified specialists with conducting fundamental and applied scientific research. In this regard, an important event for the university was the opening (1968) of the Research Institute of Applied Mathematics and Mechanics (the first director was A.D. Kolmakov). In the same 1968 the Research Institute of Biology and Biophysics was opened (the first director was V.A. Pegel). One of the indicators of the recognition of TSU’s merits in the field of scientific work was the approval of Tomsk State University as the basic university of the West Siberian Scientific and Methodological Council of the Ministry of Higher and Secondary Specialized Education of the RSFSR. The contribution of Tomsk State University named after V.V. Kuibyshev in the training of highly qualified specialists and in the development of science was marked by the awarding of TSU with the Order of the October Revolution in 1980. Over 70 professors and teachers were awarded orders and medals. In the 1960s–1970s, when Bychkov was TSU’s rector, the material base of the university improved noticeably. A new building of the Research Library was put into operation, including a 12-tier storage for 2.5 million volumes; three buildings for research institutes, a sports complex, a university stadium, four dormitories for students and one for graduate students, four apartment buildings for teachers and scientific workers, a children’s center (in Yuzhnaya Square) were built. In 1970, the reconstruction of the tropical greenhouse of the Botanical Garden began. As a rector, Bychkov used to delve into all the little details in the economic life of the university, attend lectures and exams (he attended the lectures of all professors who worked at TSU at that time); he also found time for intensive social work. Bychkov was one of the initiators of “Professor Days” (since 1978) when professors and associate professors organized lectures and talks at enterprises and in districts of the region. He was recognized for his benevolence, abilities to hear the interlocutor, to unite and motivate to accomplish the assigned task. Optimist by nature, he was able to instill optimism in those around him.

Abstract:

Dynamische Systeme, insbesondere Transportmittel, unterliegen der permanenten Forderung des Leichtbaus. Hierbei ist die Zielstellung, die Masse der technischen Konstruktionen so gering wie möglich zu halten, um vor allem den Energieverbrauch zu reduzieren. Darüber hinaus wird dieser Themenkomplex auch infolge des Leitgedankens CO2-Reduzierung durch die Bundesregierung getragen und in Forschungsprojekten gefördert. Jedoch sieht man sich beim Thema Leichtbau mit der Kostenfrage konfrontiert, denn Leichtbauwerkstoffe können im Vergleich zu den schweren Standardwerkstoffen teurer sein. Erhöhte Material- und Fertigungskosten sind im jeweiligen Anwendungsfall gegenüber der Gewichtseinsparung abzuwägen. Gerade im Automobilbau und im Flugzeugbau gehören der Leichtbau und dessen finanziellen Aufwände zum Tagesgeschäft der Entwickler. Durch die Integration des Deutschen Kunststoff-Institutes DKI im Jahre 2012 als Bereich Kunststoffe in das Fraunhofer-Institut für Betriebsfestigkeit und Systemzuverlässigkeit LBF steht nun die gesamte Prozesskette von der chemischen Harzentwicklung und Formulierung, über die simulationsgestützte Bauteil- und Systemauslegung, bis hin zur Fertigung und Prüfung für Faserkunststoffverbunde zur Verfügung.

Abstract:

The article observes public interests, firstly, as a social regulative system in the Russian law, and secondly, as a scientific conception of law in legal science. It also researches possibilities of building legal constructions based on public interests with an aim to improve the legal regulation. Basing on the general theory of law and administrative law, the authors analyze: 1) the essence and grounds of public interests; 2) transformation of the Russian historical-theoretical conceptions of public interests; 3) modern interpretations of the phenomenon of public interests in the Russian legal doctrine, legislation and judicial practice; 4) some differences in the Western and Russian conceptions of public interests; 5) separate legal mechanics based on public interests. I.e. the authors talk about objectivating public interests, defining its forms of appearance and possibilities of implementation in the Russian society, law and state. Nowadays categories «public interest», «state interest», «social interest», «general public interests» as well as similar ones are widely used in the Russian legal science, law-making and law enforcement. The problem of its defining as well as identifying public and state interests is still not solved. The article emphasizes the absence of legal definition of public interests in the Russian legislation what causes its use as an evaluation category in the law enforcement practice. This follows by uncertainty in the legal regulation. From other side the term remains flexible and movable, helps coordinate moral and legal content, allows take into account specificity of public interests in each and every case. The article observes position of the Constitutional Court of Russia which defines correlation between public interests and similar categories, e.g. general interest. According to the authors’ opinion, public interests form legal mechanics uniting legal principles, institutes and rules. Examples of such mechanics are corporate-public regulation and public-private partnership.

Abstract:

Addressing environmental security and sustainable development depends on the policy of the government, and from the technological development of society. Ideally, this is the development of technologies that are able to work on the conditions of waste-free production. Unfortunately, such technologies do not actually exist, and getting a useful product is associated with the simultaneous formation of waste both production and consumption (MSW-solid household waste), which involves the entire population of the country. The problem of waste disposal can be solved by creating waste processing plants equipped with special thermal waste disposal plants and effective multi-stage flue gas cleaning systems. In recent years, there has been increasing interest in the method of waste heat treatment in rotating furnaces, where it is possible to jointly neutralize liquid, solid and pasty waste. A similar unit with capacity of 250–300 kg/h to 5 t/h household waste developed by OOO «Fire technology» in cooperation with the Institutes of theoretical and applied mechanics, Thermophysics and operated in the Republic of Korea, China and RP Kochenevo Novosibirsk region.

Abstract:

Although rigid foam core structures have gotten a lot of attention, there have only been a few researches on foam reinforced sandwich panels with aluminum alloy A6061 sheets as face-sheets. In this research, the sandwich concept was applied to develop lightweight panels for roofing system. Analysis on the influences of core thickness, density, and foam layer arrangement on energy absorption, bending strength and displacement of sandwich panel under the quasi-static three-point bending test were investigated. Sandwich panel core is made of closed-cell polyurethane foam with densities of 40 kg/m3, 60 kg/m3, and 80 kg/m3. The quasi-static three-point bending tests were conducted in accordance to ASTM C-393 Standard and the polyurethane foam cores are design accordingly to the guideline of National Institutes of Standards and Technology (NIST). Load–displacement curves and mechanical properties are shown using data from experimental works. Results demonstrate that increased in thickness of the sandwich panel, also increased the bending strength, energy absorption and displacement. Furthermore, the sandwich panel with 50 mm thickness and 60 kg/m3 density foam core has the maximum bending strength.

Abstract:

Identifying EFL writing components involves an intricate network of principles and approaches that also involve assessment models. Methods of teaching and assessing writing are normally compatible with the purposes or expectations of writing-specific courses/programs. This study investigated the most important academic writing constructs in Iranian EFL students based on principal component analysis. To this end, an Oxford Placement Test (OPT) was administered and based on its results, 60 (out of 114) Iranian EFL male and female learners from Islamic Azad University, Broujerd Branch, Iran, were randomly selected as the homogeneous sample of the study. Additionally, 100 EFL teachers from four language institutes were asked to participate. Three instruments were used, namely OPT, a survey questionnaire, and writing tasks. The data were analyzed through principal component analysis. The findings revealed that the most important constructs in the Iranian EFL students’ writing skills were “mode”, “assessment”, and “mechanics”, respectively. The findings of the study suggested implications for L2 writing improvement from a practical and theoretical perspective. The findings, more specifically, could shed light on current practices and theories, and could prove useful for practitioners and future studies in the field of second language writing.
