Causative mechanisms and functional correlates of MTT reduction in stallion spermatozoa
Authors: Medica Ashlee Jade , Gibb Zamira , Sheridan Alecia , Harrison Natasha , Aitken Robert John
Published: March 2022

MTT is a commonly used cell vitality probe, due to its ability to form insoluble formazan deposits at cellular locations of intense oxidoreductase activity. Although this response is considered a reflection of mitochondrial redox activity, extra-mitochondrial sites of MTT reduction have been recognized within the spermatozoa of several mammalian species. Therefore, the aim of this study was to determine the major sites and causative mechanisms of MTT reduction in stallion spermatozoa. Our results show that stallion spermatozoa displayed substantial mitochondrial formazan deposition, as well as a single extra-mitochondrial formazan deposit in various locations on the sperm head in approximately 20% of cells. The quality and capacitation status of stallion spermatozoa were positively correlated with the presence of an extra-mitochondrial formazan granule. Additionally, extra-mitochondrial formazan deposition was suppressed by the presence of an NADPH oxidase (NOX) inhibitor (VAS2870; active against NOX2, NOX4 and NOX5), MnTMPyP (SOD mimetic) and zinc (NOX5 inhibitor) suggesting that extra-mitochondrial MTT reduction may be facilitated by NOX-mediated ROS generating activity, conceivably NOX5 or NOX2. When comparing MTT to resazurin, another well-known probe used to detect metabolically active cells, MTT reduction had a higher correlation with sperm concentration and motility parameters (R2= 0.91), than resazurin reduction (R2 = 0.76). We conclude that MTT reduction in stallion spermatozoa follows a species-specific pattern due to a high dependence on oxidative phosphorylation and a degree of NOX activity. As such, MTT reduction is a useful diagnostic tool to assess extra-mitochondrial redox activity, and therefore, the functional qualities of stallion spermatozoa.

Published: March 2022

La pandemia de COVID-19 ha impactado al turismo religioso en México en número de peregrinos y derrama económica: el objetivo del artículo es analizar mediante un estudio observacional con fuentes documentales y hemerográficas la afectación del sector durante 2020 y 2021 en el estado de Jalisco y la respuesta de las autoridades. Antes de la pandemia, los santuarios mostraban un elevado número de visitantes y tenían gran importancia para la economía regional. En las celebraciones religiosas de San Juan de los Lagos, los visitantes disminuyeron de 2 millones de personas en 2019 a 2.500 en 2020, en Zapopan de 1,8 millones a 1.300 y en Talpa se registraron 20 visitantes. Dichos santuarios han mantenido su continuidad por redes sociales y telecomunicaciones, desarrollando nuevos lazos con los peregrinos. La cooperación de autoridades locales y religiosas, comerciantes, hoteleros y visitantes es clave para la recuperación del turismo religioso en la nueva normalidad.

Introducción. Colombia tiene una variedad de territorios, de gente, de culturas, de afiliaciones políticas y religiosas, sin embargo, ha sido afectada por una historia de violencia, de desigualdad, de corrupción, de politiquería, entre otros, hechos asociados con la falta de tolerancia, la diferencia y la desprotección a las comunidades y las minorías. Objetivo. El estudio se propuso develar los saberes producidos por las organizaciones, sus modos culturales de construcción de conocimiento, aprendizajes interculturales, prácticas educativas y saberes. Como apuesta contrahegemónica se planteó visibilizarlas a partir de sus territorios, sus historias de vida y sus experiencias. Metodología. Se llevó a cabo desde la investigación-acción-participación, con 38 personas coinvestigadoras de 10 organizaciones a partir de encuentros pedagógicos/investigativos, de visitas a territorios, círculos de reflexión y entrevistas. Resultados. Se identificaron líneas de fuga en clave de la descolonización de las manifestaciones estéticas, epistémicas y la configuración de la pedagogía en territorio como vehículo de relaciones, el cuidado de si, de los otros en espacios comunes desde diálogos y prácticas plurilógicas y pluriculturales. Conclusiones. se logra evidenciar el reconocimiento de una diversidad epistémica y una pedagogía otra, esto es, un llamamiento de otras lógicas/ruptura de la idea unitaria de mundo. Al interior del proceso de educación de las organizaciones también es posible encontrar trayectos para educar diferenciales, donde los conceptos y los métodos educativos se desinstalen del tiempo pasado, presentados como aconteceres cotidianos que son interrogados en espacios deliberativos.

Published: March 2022

Introducción. La educación inclusiva está actualmente consolidada en lo referente a sus planteamientos y bases teóricas; pero la puesta en práctica de la inclusión en los centros educativos ordinarios requiere una actuación distinta del proceso de enseñanza-aprendizaje, que no está aún consolidada. Objetivo. Determinar como la aplicación de las metodologías activas, dentro de educación primaria, favorecen el proceso de inclusión educativa, mostrando como la Presencia, la Participación y el Progreso de todo el alumnado puede ser una realidad en los centros y aulas escolares. Metodología. Se presenta un estudio explicativo de corte cualitativo, con la participación de ocho maestros y maestras de primaria de diferentes escuelas de Mallorca, con los que se realizaron seis sesiones de grupo de discusión para la recogida de la información, posteriormente se efectuó un análisis, mediante el software de análisis de datos NVIVO, a partir del método deductivo. Resultados. Los resultados ponen de manifiesto cómo las metodologías activas pueden ser inclusivas sí atienden a determinados factores tales como la necesidad de una presencia física y emocional vinculada a la identidad grupal del aula; la participación real en procesos de planificación, comunicación y a partir de equipos cooperativos y el desarrollo de un aprendizaje competencial. Conclusiones. Se destaca el rol docente y su intervención como elementos clave de las buenas prácticas inclusivas en los centros escolares, donde la presencia, participación y progreso del alumnado son tres eslabones progresivos de actuación docente y un punto de partida para la mejora y el desarrollo profesional.
A novel approach: Handmade papermaking
Authors: Bhodiwal Shweta , Chauhan Sunita , Agarwal Reenu , Barupal Tansukh
Published: March 2022

We can say that handmade paper is the heritage art of India which gives a huge opportunity of creating something novel only with very few resources. The paper industry is a forest based industry. Depleting forest cover is a major cause of concern. Thus the sustainable method for this is handmade paper making. Handmade paper industry is one of the fastest growing industries in India. Paper can be made either synthetically or naturally. Synthetic papers are generally preferred for work yet these papers have unfavorable impact on the climate and this can be replaced by handmade paper. The paper industry is a forest based industry. Depleting forest cover is a major cause of concern. Agricultural waste disposal is a major problem because of the presence of cellulose content and high lignin which results in pollution and affects the environment, which are very difficult to degrade. The misuse of natural resources has come closer to the limits of earth’s capacity. The life cycle of mill made paper actually damages the environment from beginning to the end. Thus the study emphasizes on alternative eco-safe materials for production of handmade paper. The main purpose is to highlight the potential of agriculture waste used as non-wood materials for paper production.
A New Species of Rhagoletis (Diptera: Tephritidae) from Switzerland, with Discussion of its Relationships within the Genus
Authors:   1Schmalhausen Institute of Zoology NAS of Ukraine, Korneyev S. V.
Published: March 2022

Rhagoletis merzi sp. n., is described and illustrated based on specimens swept and reared from Juniperus sabina L. in Switzerland. A comparative review of Palaearctic species and a key to Palearctic and Nearctic species similar to R. merzi is provided. Based on DNA sequences from the COI, CAD, 28S, period, and AATS genes (4270 bp) of 92 isolates from two outgroup species (Anastrepha ludens, Euphranta canadensis), one species of Carpomya and 35 species representing most of species groups of Rhagoletis, a MrBayes analysis recovered a monophyletic lineage of Juniper-infesting species within a monophyletic cluster of R. fausta, R. batava, as well as the suavis, cingulata, pomonella, tabellaria and juniperina groups. Th e juniperina group includes both Nearctic (R. juniperina and undescribed forms) and Palaearctic species (R. fl avigenualis and R. merzi). Rhagoletis merzi is more similar to the Nearctic R. juniperina in both morphological characters (wing pattern, occiput, mesonotum and legs coloration, shape of male surstyli) and molecular sequences than to the Palearctic R. fl avigenualis.
Factors Affecting Avifaunal Diversity in Selected Agro-Ecosystems of Himachal Pradesh Agricultural University, Palampur, Himachal Pradesh, India
Authors:   Tea Research Institute of Sri Lanka, Talawakelle, Sri Lanka, Kottawa-Arachchi J. D.
Published: March 2022

Avifaunal diversity in eight different habitats of Himachal Pradesh Agricultural University, Palampur was studied in order to find factors affecting the occurrence of bird species. Bird populations were sampled in different agro-ecosystems such as farm fields (experimental and organic), wetland, abandoned tea plantation, administration area, playground, secondary forest and stream vegetation. A total of 125 species of birds belonging to 51 families, including 33 winter visitors and 27 summer visitors have been recorded. Among them, 78 insectivores followed by 18 carnivores were recorded. The abandoned tea field was a diverse habitat that maintained the highest species richness recording 50 species, followed by stream vegetation and organic farm. Seasonal variations and habitat heterogeneity play crucial role in shaping species richness. Plant diversity, vegetation structure and microhabitats support different feeding guilds, temporary refuge and migratory route which result in increased bird diversity. Based on different categories of birds, the cluster analysis revealed three distinct clusters of habitats, first cluster containing administration area and secondary forest habitats, experimental farm and wetland grouped in cluster II, whereas cluster III contained habitats viz. abandoned tea plantation, playground, organic farm and stream vegetation. Several conservation measures such as increasing plant diversity, conducting regular and long-term systematic studies, introducing bird friendly management plan are recommended to conserve and enhance avifaunal diversity in the university.

Authors: Burchard Paul R. , Lay Raymond , Ruffolo Luis I. , Ramazani Suzanne N. , Walton J. Mark , Livingston Michael H.
Published: March 2022

BACKGROUND AND OBJECTIVES

Premature infants are often given glycerin suppositories or enemas to facilitate meconium evacuation and the transition to enteral feeds. We reviewed the best-available evidence for the use of glycerin suppositories and enemas in premature infants.

METHODS

We searched MEDLINE, Embase, and Cochrane Central for randomized controlled trials (RCTs) of premature infants treated with glycerin suppositories or enemas through January 2022. Studies were screened and data extracted independently and in duplicate. We included RCTs of premature infants <32 weeks gestation and/or birth weight <1500 g who were treated with glycerin suppositories or enemas. Meta-analysis was performed using random effects and reported as relative risk or mean difference.

RESULTS

We identified 6 single-center, RCTs of 389 premature infants treated with glycerin suppositories (n = 207) or enemas (n = 182). Mortality rates ranged from 0% to 17%, and the meta-analysis revealed no differences between treatment groups (P = .86). Active treatment was associated with earlier meconium evacuation (mean, 1.5 days; 95% confidence interval, 3.0 to 0.01; P = .05) but not a faster time to enteral feeds (mean, 0.5 days; P = .48). We identified 1 ongoing trial with a target recruitment of 220 premature infants. The quality of evidence was very low to moderate because of inadequate statistical power and other methodologic issues.

CONCLUSIONS

The use of glycerin suppositories and enemas in premature infants is associated with earlier meconium evacuation, but the clinical significance of this finding is uncertain. Treatment has no definitive effects on mortality, necrotizing enterocolitis, or enteral feeds.
The Influence of Teaching Quality, Social Support, and Career Self-Efficacy on the Career Adaptability Skills: Evidence from a Polytechnic in Indonesia
Authors: Mahfud Tuatul , Mulyani Yogiana , Setyawati Ria , Kholifah Nur
Published: March 2022

Introduction. Changes in the industry impact the stable condition of working in a company or industry and it is not something that can be guaranteed again in the future. The proof is that there are many phenomena of job transfers or even layoffs in various business sectors due to COVID-19 pandemic. Many studies have examined the importance of developing career adaptability skills to face the changing needs of the industry. However, studies that discuss the mechanism of forming career adaptability skills involving important antecedent factors such as teaching quality, social support, and career self-efficacy of polytechnic students are still limited. Therefore, this study aims at examining the effect of teaching quality, social support, and career self-efficacy factors on the career adaptability skills of polytechnic students.
Materials and Methods. This study involved 265 students at a polytechnic in East Kalimantan, Indonesia. The students expressed their perceptions of the quality of their internship learning, social support, and career selfefficacy – data analysis used Structural Equation Modeling by Amos 18 software.
Results. This study reveals that teaching quality and social support does not have a direct effect on career adaptability skills. Meanwhile, career self-efficacy has a direct effect on the career adaptability skills of polytechnic students. Other findings, teaching quality and social support have a direct effect on the career self-efficacy of polytechnic students. Finally, career self-efficacy mediates the effect of teaching quality and social support on the career adaptability skills of polytechnic students.
Discussion and Conclusion. This study provides important implications for the development of learning in vocational education so that students have a good mastery of career adaptability skills. Vocational education practitioners must design a vocational teaching model that combines vocational teaching, social support, and career self-efficacy to form mastery of career adaptability skills for pop-polytechnic students. In addition, the development of a vocational education curriculum needs to include mastery of career adaptability skills for students in vocational education, be it vocational high schools or polytechnics. In further research, it is necessary to develop a vocational learning model that aims to inculcate career adaptability skills for vocational students.

Introduction. Many foreign students study at universities in the provincial regions of Russia. At the same time, research into criteria and factors that influenced the choice of a Russian regional university among foreign students have not been carried out until now. The main purpose of the study is to identify the criteria and factors of the attractiveness of a university located not in the capital region, but on the periphery of Russia, according to foreign students.
Materials and Methods. Stages of the research: analysis of statistics on the number of foreign students in Russia, analysis and generalization of literary sources in the field of identifying the motives of applicants when making a decision to study at a foreign university, a sociological survey of foreign students studying at universities in the Volga Federal District, processing and generalization of the survey results, development of recommendations to increase the attractiveness of Russian higher education for foreign applicants.
Results. According to the results of a sociological survey among foreign students studying at universities of the Volga Federal District, the attractive factors of choosing Russia as a country for higher education, as well as repulsive (negative) factors in their native country, were revealed. The reasons and goals of admission to the Russian university, the sources of information about Russia and the university, the criteria for choosing a Russian university were analyzed, the strategic goals of foreign students after graduation were identified.
Discussion and Conclusion. The conclusions made by the authors contribute to the development of theoretical approaches and methodological tools for studying the choice of foreign universities by foreign students for their studies, identifying the motives and factors that influenced this choice. The materials of the article will be useful to scientists and researchers dealing with such problems, as well as to federal and regional governments, ministries of education, regional universities in developing programs to increase the international competitiveness of higher education in Russia and attract an international contingent of students.
Social Practices of Resource Provision in the Non-Profit Sector of the Resource Region
Authors: Urban Olga A. , Demchuk Natalia V.
Published: March 2022

Introduction. The relevance of studying social practices in the non-profit sector is due to the need to identify the potential of non-profit organizations in the development of the social sphere of the resource region. The purpose of the article is to study institutional opportunities and obstacles in providing non-profit organizations with the resources necessary for the development of the social sphere and reducing social risks of the population of resource regions.

Materials and Methods. The conclusions of the article are based on the results of a comprehensive study of the non-profit sector of the Kemerovo region. The study was conducted by using quantitative and qualitative methods (questionnaire survey, semi-formal interview, expert survey), which allowed to identify the features of interaction of social actors in the non-profit sector. The empirical objects of the study are managers, employees of non-profit and public organizations, heads of charitable foundations established by the large companies to support local social initiatives, the population of monotowns of Kuzbass region, in which the main industrial potential is concentrated.

Results. Non-profit organizations have market restrictions in the consumer practices of the local population. A passive pattern of behavior dominates. It is an institutional obstacle to recruiting volunteers and employees and it limits the social base of the non-profit organizations. The authors prove that the prevailing of paternalistic attitudes enroots the traditional pattern and prevents partnership between the authorities and non-profit organizations in achieving common interests. Institutionalized informal practices of the intra-sectoral interaction hinder social partnership as an institutional mechanism for reconciling the interests of the non-profit sector actors in the long-term development goals. The applied significance of the article lies in the fact that the directions of transformation of institutionalized practices are proposed and the experience of organizing relevant types of support for non-profit organizations to contribute to the growth of resource availability of non-profit organizations is described.

Discussion and Conclusion. The identified imperfect practices are systemic in nature and act as an inefficient institution in terms of the resource availability of the non-profit sector in the region. The paper has the practical importance for representatives of the non-profit sector and state and municipal authorities.

Published: March 2022

Introduction. The study of organizational culture of Russian companies as a tool of improving production efficiency has been actively carried out since the beginning of the XXI century. In this regard, the study of diagnostics of new characteristics of the organizational culture of enterprises and the prediction of their responds to changes in the external environment and management systems is an topical task. The aim of the article is to carry out sustainability diagnostics of industrial enterprises of the Republic of Mordovia based on new characteristics of organizational culture, as well as to determine the factors that have an impact on various socio-demographic groups involved in the clusters of the industrial enterprises.

Materials and Methods. The study was conducted in 2019 using the expert evaluation method in accord with the adapted OСAI methodology. In the study 458 respondents of 7 industrial enterprises of the Republic of Mordovia were interviewed. The obtained expert evaluations were arranged and generalized in the framework of two groups of industrial clusters of the Republic of Mordovia. The clusters differed from each other by the types of their production and the number of employees.

Results. The study shows that the economic and administrative-management status of the region have a major impact on the current organizational culture of the industrial enterprises. It was found that the current profile of organizational culture of the enterprises has not achieved a balance ensuring most favorable conditions for sustainable development. The desired profile of organizational culture of the regional enterprises shows the aspiration of employees, regardless of their job positions, to achieve the balance state. The study has revealed that administrative and management personnel are more stressed than production personnel due to the responsibility for the current and future state of the enterprise.

Discussion and Conclusion. The research analyzes the influence of the specifics of the industrial activities of enterprises on achieving a balanced state of organizational culture as a condition for sustainable development. It shows that the development of organizational culture of industrial enterprises is affected by major regional influence consisting of a set of factors that characterizes the state of the economy, the regional labor market and the administrative management of the region. The implementation of organizational changes leading to an increase in the efficiency of the industrial activities of enterprises can be carried out on the basis of the results of this study. The article can be used by the heads of industrial enterprises of Mordovia to map an integral program for the development of the regional enterprises as efficient and fully-fledged participants of market economy.
Calculation Methods of Total Nitrogen and Total Phosphorus Distribution in Pig Manure Fractions
Authors: Shalavina Ekaterina V. , Uvarov Roman A. , Vasilev Eduard V.
Published: March 2022

Introduction. The study aims to develop and test a comprehensive calculation methodology in a case study of pilot pig complexes to verify reliability of estimates. The methods are required for reliable tracking of the nutrients flow at the farm level and for adjusting the application doses of resulting solid and liquid organic fertilizers with due account for the crop rotation in place, agrochemical analysis of soils, and specific crops to obtain the target yields.
Materials and Methods. Calculations of the content of total nitrogen and total phosphorus in pig manure before separation and in resulting solid and liquid fractions were carried out by the developed method. At that, coefficients from corresponding normative documents and results of previous research were used. Samples of initial material were collected in three replications at two closed-cycle pig rearing complexes located in the Leningrad Region. The experimental data were statistically processed with StatGraphics Centurion v.16 software.
Results. The calculated nutrient content of the manure before separation and the separated solid and liquid fractions was compared with the results of laboratory analysis of the physicochemical composition of the manure and its fractions from the selected pig rearing complexes. The difference between the calculated and average actual values of all considered indicators did not exceed 10%, with the differences in nitrogen content turning out to be much bigger (up to 10%) than the differences in phosphorus content (up to 5.7%) in the solid and liquid fractions of pig manure.
Discussion and Conclusion. The identified differences can be explained by the instrumental uncertainty and heterogeneity of the analyzed initial material ‒ a mixture of excrement and process water. The results of the study confirmed that the developed method is reliable, and it can be used to account for the nutrients in the solid and liquid organic fertilizers in calculating and adjusting doses for certain crops to produce expected yield and reduce the negative impact on the environment.

Fiscal sustainability vs tax gap – Evidence from Poland
Authors: Uryszek Tomasz , Klonowska Alina
Published: March 2022

The main goals of the article are to investigate the level of fiscal unsustainability in Poland and estimate the tax gap necessary to stabilize the size of the public debt and to follow a path to fiscal sustainability. It hypothesizes that by closing the tax gaps for value-added tax (VAT) and personal income tax (PIT), Poland can cover most of its current fiscal needs and stabilize the country’s fiscal situation. We estimated a modified version of the equation describing Ponzi games, calculated the primary gap indicator, and conducted cointegration tests for ex-post data on public expenditures and revenues to investigate the actual level of fiscal unsustainability. The research period covers yearly observations between 2003 and 2017. Empirical evidence confirmed our research hypothesis. We found out that closing the tax gap could change the situation dramatically. If the public authorities were able to collect the VAT and PIT that currently go uncollected, Poland could easily embark on the path towards fiscal sustainability.
Children's rights in European education. Dilemmas, challenges and implementation regarding Roma children in selected European countries – An introduction
Authors: Óhidy Andrea , Riddell Sheila , Boutiuc-Kaiser Alina
Published: March 2022

The UN Convention on the Rights of the Child (UNCRC) recently had its 30th anniversary. Emerging from the United Nations General Assembly in 1989, it has since become the most ratified international human rights treaty ever. Most European countries ratified it and are thus obliged to ensure the implementation of children's rights in practice. Operationalizing the UNCRC raises practical, conceptual and ethical issues. For example, questions arise concerning children and young people's competence to make autonomous decisions in different social domains, especially in education. There are also debates about children's involvement in dispute resolution and the extent to which rights must always be associated with redress in order to make them meaningful. Clearly, the relationship between the rights of children and young people on the one hand and those of parents and teachers on the other are particularly salient. In addition, challenges may arise in relation to children from the Roma-minority in educational institutions. Article 28 (1) of the UNCRC stresses that “States Parties recognize the right of the child to education, and with a view to achieving this right progressively and on the basis of equal opportunity”. Nonetheless, Roma students frequently experience multiple forms of discrimination in educational institutions which amplify their existing disadvantage. Across Europe, there have been different rates of progress in terms of incorporating aspects of the UNCRC into domestic law and put them into practice in schools and other education institutions, and in many cases Roma children have yet to experience the benefits of enhanced children's rights.
Kísérlet néhány magyarországi ötvösjegy feloldására XIX.

Published: March 2022

To continue my previous papers, I wish to present and try to elucidate the new makers’ marks and mark variants found in private collections and the art trade. The time interval is again the 18–19th centuries. The first to be mentioned are the twin capital cities Buda and Pest, as well as Óbuda. In Buda, new data have been found about Franciscus Mechthler, in Pest about Carolus Schmidt and Menyhárt Boll, in Óbuda of Fülöp Adler. This is followed in alphabetic order by several cities of the Hungarian Kingdom. Arad (Arad, R), Balassagyarmat, Besztercebánya (Banská Bystrica, Neusohl, SK), Eger (Erlau), Esztergom (Gran), Győr (Raab), Igló (Spišská Nová Ves, SK), Kassa (Košice, Kaschau, SK), Kismarton (Eisenstadt, A), Liptószentmiklós (Liptovský Svätý Mikuláš, SK), Losonc (Lučenec, Lizenz, SK), Miskolc, Nagybecskerek (Zren­ janin, SR), Nagykanizsa (Großkirchen), Nagyszeben (Si biu, Hermannstadt, R), Rimaszombat (Rimavská Sobota, Großsteffelsdorf, SK), Selmecbánya (Banská Štiavnica, Schemnitz, SK), Szatmárnémeti (Satu Mare, Sathmar, R), Szentendre, Temesvár (Timişoara, Temeswar, R), Tolna, Zágráb (Zagreb, Agram, HR). The weight of new infor­ mation varies by settlements. In some places only a new version of the known hallmark was found, there are places where new goldsmiths were come across or new biographic data were found of known masters. Finally, I enumerate the goldsmiths’ works in Hungary which display Viennese city mark imitations in addition to the makers’ marks. The article is accompanied with a diagram of 117 goldsmiths’ marks.

Bevezetés

Az arteria (a.) brachialis aneurysma ritka előfordulású kórkép, mely a perifériás aneurysmák 5%-át teszi ki. Többsége pseudoaneurysma, mely iatrogen behatás vagy trauma hatására alakul ki. Ismert entitás az elzáródott, dialízis céljából készített arteriovenosus (AV) fistula után kialakuló valódi a. brachialis aneurysma. A szerzők egy 43 éves, két alkalommal vesetranszplantáción átesett páciens esetét mutatják be, aki akut bal kar ischaemia miatt került kórházba. Művesekezelés céljából a beteg először bal oldali Cimino fistula képzésen, majd az első transzplantált vese rejectióját követően bal oldali brachiocephalicus AV fistula képzésen esett át. A képalkotó vizsgálatok (angiographia, CT angiographia) bal oldali a. brachialis aneurysmát és a korábbi brachiocephalicus arteriovenosus (AV) fistula thrombotizált vénás szárának tágulatát és perifériás embolisatiót igazoltak. A beteg sikeres kezelése kórházunkban több szakma bevonásával történt. A kiáramlási pálya megnyitása minimál invazív katéteres thrombolysis segítségével, az embóliaforrás kiiktatása hagyományos érsebészeti módszerrel, az aneurysma lekötésével, az elzáródott tágult vénás szár resectiójával és autolog vena saphena bypass végzésével történt. Az eset ismertetésével a szerzők a sikeres kezeléshez vezető komplex gondolkodásmódra szeretnék felhívni a figyelmet.
A review on chemical bath deposition of metal chalcogenide thin films for heterojunction solar cells
Authors: Sengupta Sucheta , Aggarwal Rinki , Raula Manoj
Published: March 2022

Heterojunction (HJ) thin-film II–VI solar cells are emergent substitutes to the traditional silicon solar cells because of improved efficiency and cost-effectiveness. A renewed interest in depositing the constituent layers employing chemical bath deposition (CBD) is shown because of the absence of any stringent reaction conditions which ensures the preservation of the properties of the constituent layers. Variation in the growth conditions has strong effects on the morphologies and the properties of the resultant films specially the interface. Inappropriate or alloyed interfaces may result in pinholes formation affecting the resultant electric field because of reduced junction area and enhanced recombination for carriers which in turn affects the efficiency. In this review, we provide an overview of the different combinations of metal chalcogenide/chalcopyrite thin-film layers for HJ solar cells by CBD and achieving control over the resultant morphology, particularly focusing on interfacial epitaxial relationship which is found to have substantial influence on the efficiency of the resultant cell.

Graphical abstract

Heterojunction (HJ) thin-film II–VI solar cells are emergent substitutes to the traditional silicon solar cells because of improved efficiency and cost-effectiveness. A renewed interest in depositing the constituent layers employing chemical bath deposition (CBD) is shown because of its simplicity and versatility. Variation in the growth conditions like temperature and the reagent concentrations have strong effects on the morphologies and the properties of the resultant films specially the interface. In this review, we provide an overview of the different combinations of metal chalcogenide/ chalcopyrite thin-film layers for HJ solar cells by CBD and achieving control over the resultant morphology and phase composition, particularly focusing on interfacial epitaxial relationship, which is found to have substantial influence on the efficiency of the resultant cell.
Ancient Egyptian Coffins in 3D: Digital Analysis, Visualization, and Dissemination
Authors: Lucarelli Rita , Johnston Kea
Published: March 2022

This chapter discusses the importance of digital data capture techniques such as digital photogrammetry for expanding access to texts carved on Egyptian sarcophagi by creating collections of digitized large mortuary objects. Such large objects are often stored in museum warehouses and not easily shared with scholars and the public. By providing a thorough explanation of the digital techniques and results of the “Book of the Dead in 3D” project at UC Berkeley, this chapter highlights the significance of conducting text analysis on the 3D models of the coffins by creating interactive annotations--including text transcription and translation of the magical spells--on the digital models themselves. This kind of embedded metadata is critical to scholars of Egyptology. The case study presented--the sarcophagus of Psamtik in the collections of the Phoebe Hearst Museum at Berkeley--describes in detail the technique of digital photogrammetry combined with custom programming to create the annotated 3D models.
The Digital Context of At-Risk Textual Archives
Authors: Anderson Adam G.
Published: March 2022

By describing the case study of a large collection of Assyrian tablets, this chapter illustrates the benefits of digital curation and textual analysis for re-establishing the missing context of looted and unprovenienced ancient artifacts. It tackles the main theme of heritage at-risk from a different perspective than other chapters in the book. The author details the creation of an ontological structure for data analysis using digital curation methods combined with innovative machine learning and network analysis and visualization techniques. The result is an important new research tool for scholars focusing on reinterpreting ancient Assyrian cuneiform writing from unprovenienced texts.
COX4-1 promotes mitochondrial supercomplex assembly and limits reactive oxide species production in radioresistant GBM

Glioblastoma (GBM) is a fatal disease with recurrences often associated with radioresistance. Although often effective at treating newly diagnosed GBM, increasing evidence suggests that radiotherapy-induced alterations in tumor metabolism promote GBM recurrence and aggressiveness. Using isogenic radiosensitive and radioresistant GBM cell lines and patient-derived xenolines, we found that acquired radioresistance is associated with a shift from a glycolytic metabolism to a more oxidative metabolism marked by a substantial increase in the activity of the mitochondrial res-piratory chain complex cytochrome c oxidase (CcO). This elevated CcO ac-tivity was associated with a switch in the isoform expression of the CcO regulatory subunit COX4, from COX4-2 to COX4-1, assembly of CcO-containing mitochondrial supercomplexes (SCs), and reduced superoxide (O2●-) production. Overexpression of COX4-1 in the radiosensitive cells was sufficient to promote the switch from glycolytic to oxidative metabolism and the incorporation of CcO into SCs, with a concomitant reduction in O2●- production. Conversely, silencing of COX4-1 expression in normally radiore-sistant cells reduced CcO activity, promoted the disassembly of mitochon-drial SCs, and increased O2●- production. Additionally, gain or loss of COX4-1 expression was sufficient to induce the radioresistant or radiosensitive phenotype, respectively. Our results demonstrate that COX4-1 promotes SC assembly in GBM cells, and SC assembly may in turn regulate the pro-duction of reactive oxygen species and thus the acquisition of radiore-sistance in GBM.

The features of the retention indices determination in reversed phase high perfor­mance liquid chromatography (RP HPLC) are discussed, namely the different possibilities of the application of the recurrent relations. At first, not the experimental, but the precalculated values are recommended as the retention parameters of non-sorbable compound (dead time, t0) in RP HPLC. It is because just the precalculated values provide the linearity of rela­tionships lg (tR – t0) = anC + b, where nC is the number of carbon atoms in molecules of ho­mologs selected as reference compounds (n-alkyl phenyl ketones). Besides the known Peterson and Hirsch equation for the theoretical evaluation of t0 using the retention times of three consecutive homologs, the following recurrent relations are also recommended: tR(nС – 1) = atR(nC) + b, from where it follows that t0 = lim (tR)½(nC ® 0) = b / (1 – a) under the condition that 0 < a < 1. Another area of the effective application of the recurrent relations is caused by the following fact: the ranges of the concentrations of the eluent’s organic constituents during the separation of hydrophilic analytes and hydrophobic reference n-alkyl phenyl ketones may not overlap, or over­lap only partially. In such cases, expanding the data arrays seems to be reasonable using the extrapolated values both for the target analytes, and (preferably) for the reference compo­unds. For these purposes, another kind of recurrent relations can be recommended, name­ly tR(C ± DC) = atR(C) + b, DC = const. All recommendations on the application of recurrent relations in RP HPLC are illustrated with examples.
Institutions of Higher Education in the Russian Federation: Budgetary and Private Impact of Education at the University Level
Authors: Parandekar S. , Volgin A.
Published: March 2022

This article considers at the university level the graduates’ income information, as well as budgetary and private cost estimates to determine budgetary and private impact of education using the calculation of internal rate of return. Since the graduates’ income information is available for only three-year period after the graduation, the synthetic profile of the graduates’ income during their lives is constructed according to the regional microdata. Results of the calculation show that the average impact of higher education is about 9 %, which is consistent with other estimates. In addition to list of universities indicating their impact, the article presents conclusions and recommendations, based on the analysis of the impact’s types and the correlation with other parameters, particularly with Unified State Examination scores for entry into higher education. The article’s value consists in demonstration of the possible approach for estimates, considering impact of investment in higher education at the university, faculty or department level. Researchers of the future can build on methodology and estimates, presented in this article, to obtain more accurate and reliable data on private impact of investment in higher education.

Barriers to Academic Career Development for University TeachersThe relevance of the issue in the present study is determined by the fact that it is difficult to engage and retain employees (including young ones) in the academic sphere because of various career barriers, which complicate pursuing a career in higher education. The study was conducted using the method of expert interviews with 108 full-time employees of Russian universities including administration, management, academic and teaching staff. These interviews identified the key barriers to academic careers for researchers and also classified these barriers. Presented findings can be useful for HR departments of higher education institutions for building various career paths for the employees of different ages, or for identifying specific types of barriers in career development to be overcome. The results of the study are relevant for academic and teaching staff interested in career development. The prospect of further research is to conduct a quantitative analysis based on the questionnaire results received from interviewing academic and teaching staff with the use of the proposed classification of academic career barriers.
