Published: June 2023

Evaluating the disturbance of coal beds is important both in terms of conditions of their working out and in predicting such features as methane capacity, outburst hazard and spontaneous combustion. One of the methods for evaluating coal disturbance is its research using optical microscopy. Coal consists of petrographic microcomponents (macerals) distinguished by optical properties and, most importantly, strength properties. This heterogeneity of the coal matter largely determines the nature of coal disturbance. This paper shows the impact of the macerals of the inertinite and liptinite groups on the development of disjunctive and plicative coal disturbance. The purpose of the paper is to establish the features in the formation of plicative and disjunctive disturbance of coal depending on its petrographic composition. The research is carried out with the help of a video-optical complex: MBI-11, HB 200, and Scope photo software. It is noted that the more diverse the petrographic composition of coals is, the less developed fracturing under equal other conditions coals have. The petrographic composition affects the disturbance of coals not only at the level of lithotypes but also at the level of macerals. Liptinite and inertinite prevent the development of endogenous fracturing. Liptinite and inertinite contribute to the development of exogenous fracturing. An increase in the total density of coal at high stages of metamorphism levels out the effect of the petrographic composition. Coals of low stages of metamorphism are characterized by the greatest diversity of composition. With the growth of metamorphism, the difference in strength and optical properties of the macerals is gradually leveled and coals of the C-coke, F-fat marks (CF) are characterized by the greatest fracturing. To the L mark, the composition becomes even more homogenous (features of vitrinite and liptinite fully become the same) but the overall density of coal increases, and the fracturing decreases. As long as differences remain in the strength properties of macerals (low and middle stages of metamorphism) the presence of liptinite and inertinite prevents the development of fracturing. Examples of suppression of fractures by macrospores and fusinite are given in the form of microphotographs. There are cases of interlayer slipping and slickenlines. The importance of petrographic research in evaluating both rupture and plicative disturbance of coals is emphasized.
The global ESG trend and adaptation opportunities in the emerging hydrogen economy: A corporate governance perspective
Authors: Zavarkó Máté
Published: June 2023

The development of the hydrogen economy (HE) has become the main direction of climate-focused economic progress. Although the gap between the potential impact of energy companies and their actual willingness or ability needs to be bridged by corporate governance and economic policy, these dynamics are underrepresented in the literature. As environmental, social, and corporate governance (ESG) considerations could foster adaptation and developing hydrogen technologies, the goal of this systematic literature review is to explore the specific environmental and energy aspects of ESG and the adaptation opportunities which could contribute to HE development. Findings suggest that ESG as a new institution in the economy might be in line with national and international policies, but corporate efforts at improving environmental performance could be further oriented directly or indirectly toward hydrogen technologies, for example, through cost reduction initiatives, favourable taxation, or specific requirements for sustainability reporting. On the corporate level, external and internal change drivers could lead to strategic and governance adaptation measures in line with HE development policy. The study contributes to the literature through the intersection analysis of the global ESG trend and the development policy of the HE, which has been overlooked to date, especially from a corporate governance perspective.

Long Noncoding RNA lnc-TCEA1-3 Affects Osteoclastic Function by Regulating ATP6V1H
Authors: Hou Yuzhuan , Yang Shaoqing , Zhao Zanyan , Huang Yongqing , Zhang Yanli , Ruan Wenyan , Duan Xiaohong
Published: June 2023

H subunit of V-ATPase (ATP6V1H) is specifically expressed in osteoclasts and its deficiency lead to osteoporosis. Our group previously found four intronic SNPs of ATP6V1H related to reduced bone mineral density, but the mechanisms was not clear. In this study, we found that the above four SNPs were located at lncRNA lnc-TCEA1-3 by using bioinformatics analysis. We further detected the function of lnc-TCEA1-3 on regulating ATP6V1H and osteoclast function using Atp6v1h knockout mice, lentivirus transfection and qPCR analysis. Over expression of lnc-TCEA1-3 up regulated the expression of ATP6V1H in HEK293 cells, HOS cells and primarily cultured osteoclasts, and increased the number of primarily cultured osteoclasts. In addition, over expression of lnc-TCEA1-3 exerted distinct effect on two transcripts of ATP6V1H in HEK293, HOS and osteoclasts. This study will facilitate the in-depth analysis of the effects of ATP6V1H on bone diseases, and discover new therapeutic strategies.

Authors: Dugan Matthew , Stein Gary S. , Khan Shamima , Clifford-Bova Sheila Clifford-Bova , Pilcher Finlay , Carney Jan Kirk
Published: June 2023

The human papillomavirus is associated with a range of cancers. A vaccine introduced in 2006 has dramatically decreased the incidence of these cancers, but Americans still experience over 47,000 new cases of HPV-related cancers each year. The situation is worse in rural areas, where vaccination rates lag the national average, making HPV a significant health disparity issue. This article lays out an evidence-based HPV vaccine-promotion strategy that will serve as part of a campaign to improve health equity in rural northern New England in a process that is repeatable and sustainable. The campaign includes the following elements: partnerships with state departments of health and trusted community opinion leaders, evidence-based storytelling, local social media, traditional media, and school-based pop-up vaccination clinics. Borrowing from marketing and social marketing frameworks and guided by public health perspectives, we begin with psychographic and geodemographic information about our target audience, followed by a discussion about relevant models, frameworks, and research related to persuasive storytelling. We conclude with the outline of a guidebook to foster the creation of persuasive stories as part of a sustainable, replicable HPV vaccination campaign.

Published: June 2023

Heat transfer can be realized by increasing the surface area with designs in various geometries and sizes in a compact plate heat exchanger (PHE). However, designs with low volume and high heat transfer area cause high pressure drop. In order to overcome this problem, this study examines the pressure drop of a shark-skin-patterned PHE designed using biomimicry approach. The structure of shark skin consists of an array of pulpolites called dermal denticles. This study is carried out for the first time, taking into account the friction-reducing effect of such structure on nonsmooth surfaces. A dermal denticles-patterned PHE is designed for the first time. The numerical results of the dermal denticles-patterned PHE are compared with those of a standard chevron-type PHE. The results of this study show that the heat transfer rate of the dermal denticles-patterned PHE increases by 50% compared to the standard chevron-type PHE. A 72.5% decrease is provided from the pressure drop of the standard chevron-type PHE. The mechanism that causes the reduced pressure drop is discussed in detail in the article.
Influence of recycled display glass e-waste on ternary dune sand mortar engineering properties
Authors: Toufik Choungara , Ghrieb Abderrahmane , Abadou Yacine
Published: June 2023

The present study explores the feasibility of using recycled materials from display glass electronic waste (DGE-waste) in the production of cementitious mortars as a granular corrector for dune sand and as a cementitious addition. The effects of the DGE-waste replacement ratio (5–20% with 5% steps by weight of three types of dune sand from three different regions) on the engineering properties of reinforced cementitious composite were experimentally investigated to assess the performance of dune sand mortar. The results show that the incorporation of DGE-waste in dune sand mortar can increase the mechanical strengths (flexural and compressive) by up to 35% and 43%, respectively, and improve the dynamic modulus of elasticity by at most 12% as compared with the control mortar, as well as decrease open porosity by up to 28%, which reduces micro-cracks and voids. When cement is replaced with 15% recycled DGE-waste, the mechanical strength and dynamic modulus of elasticity, as well as open porosity and absorption, are decreased by 4–7% and 17–20%, respectively. Considering the environmental impact and engineering properties, the optimal percentage of DGE-waste incorporation is 15% for cement replacement and 20% for dune sand replacement.

PASSPORT OF THE MUNICIPALITY IN INFORMING ABOUT THE TERRITORY (CASE-STUDY: THE REPUBLIC OF KHAKASSIA)
Authors:   Khakass State University named after N.F. Katanov, Eremeeva Olga
Published: June 2023

The article examines the passport of the municipality as a comprehensive source of data on various characteristics of the territory. The purpose of the article is to analyze the opportunities and problems of using the socio-economic passport of the municipality as a comprehensive source of information for different groups of users interested in the territory. The study of passports of municipalities of the Republic of Khakassia has been carried out. To source the information we used official websites of municipalities of the Republic of Khakassia and the database of municipalities of Rosstat. The data of passports of municipalities were compared with the data of official statistical information. We have analyzed the passports' indicators for their sufficiency to characterize the natural, industrial, financial, human, social and infrastructural capital of the territory. The conclusion is made that the existing system of passports of municipalities does not solve the problem of informing the interested users about the territory. It is proposed to develop a new approach to the formation of territorial reporting, based on the principles of integrated reporting.
REVIEW OF HIGHER EDUCATION FINANCING MODELS: FUNDING MECHANISMS AND THE ROLE OF THE STATE
Authors:   National Research University Higher School of Economics, Dmitrienko Aleksandr
Published: June 2023

The paper considers the higher education financing models used in different countries. The funding mechanisms, as well as the role of the state in financial resources allocation, are discussed. An analysis of a wide range of research papers shows that there are two key financing models in accordance with a typology of budgetary financing approaches: institutional and demand-based. In the institutional model of higher education funding, the object of financial flows is represented by universities, while in the demand-based model it is students. The models may include different sets of mechanisms to fund. Each mechanism, in addition to the conditions for obtaining budget funds, contains an institutional framework which determines the procedure for spending funds for the needs of the university. The results of the analysis demonstrate that the format of the higher education budgetary financing system is a derived element from the institutional landscape of the state and the form of public finance management. At the same time, the role of the state is largely determined by policy aspects related to the structure of funding and the level of universities autonomy.
REPUTATION IN PUBLIC PROCUREMENT: REGULATORY FEATURES, KEY INDICATORS AND PERFORMANCE EVALUATIONS
Authors:   National Research University Higher School of Economics, Emelianova Milena
Published: June 2023

The article presents a literature review on reputation factor in public procurement. Reputation is one of the tools for solving the principal-agent problem, which is typical for contractual relations. In line with the spread of New Public Management theory in public procurement, alternative methods of supplier selection are being developed, in particular, based on suppliers’ reputation. In contrast to the private sector, public buyers’ ability to consider reputation when choosing a supplier is highly regulated. It is shown that in the world practice of public procurement the reputation of suppliers is considered to varying degrees, there is no single approach to indicators, mechanisms for providing information and procedural aspects. Therefore, it is timely to analyse the arguments for and against expanding the possibilities of reputational considerations in public procurement. To answer this question, a separate block focuses on the effects of reputational considerations in public procurement in terms of barriers to entry, public procurement efficiency, and building trust between procurers and suppliers. Conclusions about the positive effects of reputational considerations are of interest to procurers who decide on the choice of supplier evaluation criteria. Relevant aspects of reputational considerations for Russian regulation concerning reputation indicators and mechanisms for providing information are identified. The article differs from existing reviews on the topic of reputation by focusing on the specificity of public procurement. An original classification of sources is presented in accordance with the following parameters: definitions and indicators of reputation, possibilities and limitations of reputational considerations and their effects in public procurement. Poorly studied aspects of interest for further research are identified.

diversidad no es perversidad
Authors: Affectio Societatis  , Uribe Cano Juan Manuel
Published: June 2023

El presente artículo explora los cimientos del saber psicoanalítico en su génesis y, con esta, la pregunta por lo fundante humano: el reconocimiento de un cuerpo y un psiquismo sexuales. De otro lado, aborda la relación entre la identidad humana en relación con la sexualidad, la pulsión, sus objetos y lo diverso que connota la “pervertida” sexualidad humana por efecto de la introducción y caída del significante en el cuerpo. Finalmente, propone una revisión de la anatomía y el destino biológico de los cuerpos para sostener desde allí que cuando se trata de la sexualidad y de Eros, en relación con el gozo, hay un escenario en el inconsciente del cual se ocuparán en adelante la teoría y la praxis psicoanalíticas.

This study looks at illustrated popular literature as a tool for shaping its readers–viewers’ perceptions of national histories. The author explores this issue through the example of Rudolf Herzog’s book for German school students «History of Prussia» ("Preußens Geschichte'', 1913) illustrated by Arthur Kampf and Georg Belwe. Despite the book’s popularity in the 1910s, this paper offers its first academic examination. The study combines terminology and methods coming from the fields of history of representations, political mythologies’ and visual cultures studies as well as art history. The author also adheres to methodological recommendations formulated by researchers in illustrated literature. The paper demonstrates that «Preussens Geschichte» exemplifies personality- and event-centred «official-nationalist» approach to history writing. The book’s contents reflect the current political situation and seek to promote the imperial government’s agendas as well as certain moral values. The author argues that the specific purpose of Kampf and Belwe’s illustrations consisted in stressing and simplifying the book’s key subject matter and facilitating its memorisation. The ballads performed the same function. The author maintains that the stylistic unity and repetition of similar subject-matter in Belwe and Kampf’s work contribute to the book’s overall representation of Prussia’s history as a coherent narrative. Belwe’s pictures encapsulate the book’s main ideas through the use of generalised images rather than directly translating Herzog’s prose and poetry into pictures. Kampf’s illustrations further stress the role of monarchy and army as the key actors of Prussian history through the artist’s selection of subject-matter and employment of artistic devices. Together with Herzog’s text, his pictures promote determination, courage, and self-sacrifice for the sake of the country. Two other themes that dominate Kampf’s illustrations are the bond between the monarchy, the nation, and the church (an element of The Second Reich’s official nationalism) as well as Prussia’s technological advancement as an epitome of its political power.
The Image of War in America and the Image of America in War: the U.S. Visual Propaganda Strategies in 1939-1945

The article explores the strategy of American visual propaganda during World War II. The author demonstrates how the methods and forms of propaganda reflected the general trends in the socio-political life of the United States from 1939 to 1945. The strategies adopted by the state were aimed at shaping the image of the war within the country, which was geographically distant from the theaters of war, as well as creating practices for representing the image of America in the global conflict. This approach was driven by the fact that the issue of relations between the United States and the outside world, particularly with European countries, was traditionally associated with the problem of self-identification of Americans, who were born as a nation in the struggle against the former metropole. It has been established that the success of military propaganda was ensured, in particular, by the infrastructure of social relations in the field of art created by the New Deal reforms, namely, the Federal Art Project (FAP) program. Collaborating with the state in the 1930s, artists emphasised the «American» and democratic nature of US art, which allowed it to be successfully instrumentalised during the war to serve ideological needs. According to the author, one of the most demonstrative examples is the interpretation of the concept of «Four Freedoms» by F. D. Roosevelt in the paintings of N. Rockwell, who «translated» the president's abstract statements into a visual language understandable to the people. Several projects organized by the Museum of Modern Art (MoMA) in New York, which were supported by US ministries, are also indicative. These include the 1941 war poster competition and the exhibition project «Airways to Peace. An Exhibition of Geography for the Future,» featuring politician W. Willkie. Due to the predominant use of radio and cinema in the dissemination of propaganda, the work of MoMA during World War II acquired special significance: both the artist and the viewer were endowed with an important social function of participating in the defense of the country's freedom and independence. The article shows how the direct involvement of the population in the process of propagating (re)production contributed to the rapid acceptance by Americans of the political goals of the United States during the war and in the post-war world.

The paper looks at the works of modern Ukrainian graphics (both printed and digital), which dealt with the events of the war in Ukraine from 2022 onwards. It focuses on the artworks, which use Christian symbolism and iconography and looks at how these symbols were reinterpreted in the context of modern visual culture and the current expectations of Ukrainian society. The study is structured around the categories of cultural memory and representation, in particular the visual and narrative strategies when dealing with the wartime events. It, too, is informed by approaches of visual studies, developed in the works of W.T.J. Mitchell, D. Freedberg, and T. Wright, which helped to determine the primary message of the artworks, secondary elements, and to treat them as a very specific visual message. To systematise the graphic material collected after the full scale invasion 2022, a topical approach was chosen, which means that the focus was not on the chronology of the war, but on the crucial categories in the subject matter of the religious imagery: images of the Mother of God, holy warriors, motifs of the Passions, martyrology, etc. The artworks in question demonstrated a shift from conventional patterns of religious iconography to updated ones. For example, the theme of Christ’s Passion and the tools for torture was altered to become an image of Ukraine's suffering in the course of history with all the struggles and losses of political independence and constant resistance through these centuries. Obviously, the photos and videos from the war omnipresent in the mass and social media became an important visual basis for most graphic works. The article reveals the process of transforming the local war narrative into a universal one, by virtue of the mental imagery fixed in the Ukrainian public consciousness. Analysing the graphic artists’ responses and their use Christian imagery demonstrated how the war stimulated the creation of a new mythology, a new pantheon of heroes, designed to motivate, resist and , ultimately, lead to victory. The images of Christian saints, whose iconography was reinterpreted in several graphic works, gained particular importance for forming this new mythology.

Socio-Political and Cultural Environment of Azerbaijan Press in the End of XIX – the Beginning of XX Century

The article discusses the historical conditions for formation of the Azerbaijan press, which conveyed to the people the socio-political problems of the Caucasus and the East, emanating from religious fanaticism, alienation of the Muslim society from science and education, lawlessness, caused by ignorance. The research method was historical one aimed at studying the specific circumstances of formation of conditions for printing the Azerbaijan press. In particular, these processes that took place in the society in the last decades of the 19th century were the unchanging model of tough imperial policy, and the mass illiteracy of the people. The issues of need to create the pro-gymnasiums for the Muslim community and the efforts of our intelligentsia to conduct the classes in their native language in the schools were touched in the newspapers. Jalil Mamedguluzadeh, the magazine editor was convinced that the magazine «Molla Nasreddin» was created by «nature and time itself» that showed the determining role of the social, political and cultural environment in creation of the Azerbaijan press. The main goal of the press at that time was to appeal to every representative of the Azerbaijan people to find the reserves that were hidden in the public consciousness, related to the real world, but that were not realized. During that specified period, the Azerbaijanis did not have any national school, national organization, or even an ordinary charitable society in the region. However, other nations had daily newspapers, weekly magazines, national secondary schools, charitable societies, banks, various scientific and public publications in their native languages. That was the situation of the Turko-Muslim population in the Caucasus. Therefore it was unthinkable for the society in that situation to have any goals related to national development.
