The paper presents the results of complex studies of the influence of mixtures of hydrogen gas with natural gas in the ratios of 10%Н2/90%СН4 and 20%Н2/80%СН4 on the operational and thermophysical characteristics of PE-80 polyethylene pipes and their material Research was conducted on an experimental stand, the diagram of which is attached. The results of comprehensive strength and thermophysical studies of the material of PE-80 polyethylene pipes, which were previously operated in the current gas distribution networks of Ukraine for 15 years, after 6 months of hydrogen exposure, are presented. In order to indicate possible changes in the properties of the material, the same complex of studies was carried out before hydrogen exposure of the samples. The influence of gas mixtures on the thermophysical properties of polyethylene pipes has been established, which is manifested in the reduction of the size of polyethylene crystallites and their orderliness in the volume of pipe walls under the influence of gas mixtures. At the same time, the appearance of crystallites of a new shape was found on the surface of the inner wall of the pipes. It is assumed that this may be caused by the competing action of methane and hydrogen molecules. In the course of conducting hydraulic tests on the resistance of pipes to internal pressure and mechanical studies on uniaxial tension, it was determined that all pipe samples, according to their strength characteristics, meet the requirements of regulatory documents issued for polyethylene pipes used for natural gas transportation. The relationship between the concentration of hydrogen in the mixture and the degree of its influence on the strength characteristics of the samples was established. No changes in the chemical structure of the material of polyethylene pipes were detected. It should be noted that the given results are only the beginning of a more detailed study, during which it is also planned to investigate the effect of hydrogen mixtures on technical polyethylenes after 12 and 24 months of hydrogen exposure.

Authors: Borkowski Mateusz
Published: June 2023

Celem artykułu jest pomiar kapitału społecznego oraz określenie jego oddziaływania na rozwój gospodarczy wybranych gospodarek europejskich w latach 2017–2020. W pracy wykorzystano metodę modelowania równań strukturalnych z wykorzystaniem cząstkowych najmniejszych kwadratów (PLS-SEM), która umożliwia pomiar oraz identyfikację związków pomiędzy zmiennymi ukrytymi (bezpośrednio nieobserwowalnymi). Ustalono, że zaufanie społeczne jest bardziej determinowane przez zaufanie interpersonalne niż przez zaufanie względem organizacji. Ponadto stwierdzono, że zaufanie społeczne jest najważniejszym elementem ogólnej miary kapitału społecznego. Mniej ważnym w formowaniu tej zmiennej okazała się zmienna społecznych interakcji i postaw. Ustalono także, że pomiędzy zmiennymi kapitału społecznego i rozwoju gospodarczego występuje silny dodatni i istotny statystycznie związek.
Metabody in Posthuman Architecture: Virtualizing Spatial Dynamics for Transformative Spaces
Authors: Kuran İpek
Published: July 2023

This research examines the concepts of metahumanism and metabody to explore the production of posthuman space. It examines the dynamic nature of posthuman space, which is characterized by fluidity, lack of form, and the interplay of relationships and interactions. Using Deleuze's distinction between the virtual and the actual, this study examines how posthuman space emerges as a convergence of these concepts, continuously shifting between fluid and solid states to accommodate the diverse posthuman experience. Virtualization is a crucial instrument for investigating posthuman architecture, especially within digital environments that foster creative expression and experimentation. Through a case study, this research examines the role of virtualization in forming a posthuman architectural landscape, demonstrating how digital domains offer unique opportunities for innovative space production and exploration. By highlighting the novel spaces that can be realized through virtualization, the study demonstrates the ability of posthuman architecture to cultivate new modes of interaction and engagement, thereby fundamentally altering our relationship with and perception of the built environment. This research contributes to the comprehension of the influence of virtualization on the formation of a posthuman architectural landscape by shedding light on its transformative capacities and implications.
Development: nurturing and destroying a child
Authors: Solinski Sylvia
Published: July 2023

Developmental achievements during the first five years of life are described. From birth children are readily able to engage with and respond to their caregivers, whose attunement is crucial to their welfare. The child learns to differentiate objects and people and develops schemata of relating to others. Spatial exploration and the ability to categorise facilitate the attainment of object and other permanence at around eighteen months of age. At this time children begin to understand that others are intentional agents with internal states that are the sources of attitudes and actions. The child’s identification with others is salient to the formation of identity and the ability to differentiate from others. Play is vital to understanding the nature of symbols. When attachment is secure requisite transitional space is provided and mentalization is achieved. However, a grasp of beliefs and of the difference between appearance and reality is not yet achieved. Attachment characterised by misattunement and/or overt abuse may result in pathological dissociation resulting in developmental deficits that are most extreme in dissociative identity disorder.

Authors: Nabilah Darin Farah , Tjahjadi Bambang
Published: June 2023

The image of the accounting profession has been stereotyped in various visual and social media. Stereotypes strengthen the positive and negative characteristics of the accountant's own perceptions as well as the perception of public opinion in viewing the accounting profession. The research aim is to understand how the image of accountants is portrayed by the media as stated by Honorio et al. (2022) and stereotypes related to the image of an accountant found in the films The Accountant (2016), Tooi Bigltoi Fail (2011), Wanted (2008), The Dark Knight (2008), and Rock&Rolla (2008). The theory used was social representation and stereotypes related to the image of the accounting profession in a film. A qualitative writing method with a literature study approach used to find references regarding accountant stereotypes, as well as their representation in cinematographic productions by analyzing selected films. The results of the research show that visual media plays a bigger role in reinforcing current stereotypes, through the role of accountants in film production. Demystification of several stereotypes in the character of accountants began to be more diverse, no longer represented negatively. Characteristics such as courage, intelligence and credibility are predominant among other characters. Nevertheless, the characteristics raised are not used in accordance with the accounting professions code of ethics. Research contributes to the explanation of distortions involving the image of accountants in relation to what is depicted in the film, which still does not reflect the disclosure by the film and changes the negative image of the accounting profession from the public view. Subsequent research suggests analyzing in more detail from various aspects and can answer questions about professional ethics to generate greater visibility and interest for accounting professionals in the future. This research provides novelty related to the research field of the accounting profession in the world of cinematography.

Published: June 2023

This study aims to model the diet menu problem based on a Boolean Linear Programming approach. A balanced diet is the key to a healthy lifestyle. A balanced diet is a diet that combines foodstuffs in the right amount of food components in one menu (dishes using certain recipes). When you have an unbalanced diet, your body will not get the right amount of nutrients. This is what causes the importance of managing the diet menu. Because of that, a diet menu problem model was formed based on the Boolean Linear Programming approach to cover a varied range of daily diet menu management and meet daily nutritional needs while minimizing costs. The stages of establishing the diet menu problem model are carried out by determining the notations, parameters, variables, objective functions, and some constraints related to the diet menu.

Authors: Leta Vasyl V. , Karabiniuk Mykola M. , Mykyta Mykhailo M. , Kachailo Mykhailo M.
Published: June 2023

Geoinformation technologies are an important element of professional education for future geographers and are widely used in their training program, at the same time geoinformation technologies depend on the participants` technical support in the educational process, both in full-time education and distance learning. The article examines the specifics of the application of geoinformation technologies in the organization of distance learning on the example of certain disciplines of the curriculum of future geography specialists.
The article identifies the advantages and disadvantages of distance learning on the example of the disciplines “Fundamentals of Geoinformatics” and “Cartography and GIS” studied by the students of the Department of Physical Geography and Efficient Environmental Management of the Faculty of Geography at Uzhhorod National University. The absolute advantages of this studying format for teachers are the ability to freely choose the necessary materials, academic mobility and a fundamentally new educational space. Students have the opportunity to master new disciplines in more comfortable conditions for them and in compliance with the principles of equality. At the same time, distance learning involves a wide application of an individual approach to each student, taking into account, in particular, the hardware and software necessary to work with GIS technologies.
The main disadvantages of distance learning of the academic disciplines “Fundamentals of Geoinformatics” and “Cartography and GIS” are considered. The most problematic issue for all participants of the educational process is the technical and software support at home. The process of providing students with a licensed software product taking into account different levels of hardware (personal computers, laptops, tablets) is also resource-intensive. The lack of a social environment for students is another disadvantage of distance education.
Ways and means of overcoming the indicated shortcomings of distance learning of the disciplines “Fundamentals of Geoinformatics” and “Cartography and GIS” using the geographic information system ArcGIS are proposed. While forming the structure of the educational process it is necessary to solve the problem of hardware and software, form the information content of the courses and provide access to it. Google services and the Moodle platform can play an important role here.

It was established that the conducted special course promoted the educators’ interest in bringing Earth observation to classrooms. Increased number of GIS and Remote Sensing after-school clubs in the territorial branches of the Junior Academy of Sciences (from 1 in Kyiv as of 2019 to 9 in the regions as of 2022, namely in Poltava, Sumy, Volyn, Kyiv, Kirovohrad, Zakarpattia, Lviv, Kharkiv and Chernivtsi) is indicative of the course’s effectiveness.
Diseño e implementación de una arquitectura de microservicios orientada a trabajar con transacciones distribuidas
Authors: Rodriguez Brayan , Cedeño Denis
Published: June 2023

Al trabajar con microservicios existen diferentes caminos que se pueden tomar, un sinfín de tecnologías que se pueden utilizar y por ahora no hay un camino estandarizado que los arquitectos y desarrolladores de software deben tomar para implementar este patrón de arquitectura. Para transacciones distribuidas a nivel de diferentes microservicios, no existe un camino especifico a tomar, como en tecnologías anteriores que se apalancaban en servidor de aplicaciones y componentes especializados, desarrollados a medida para tecnologías de una casa de software que lograban que la confianza en las soluciones fuese alta. Es por ello por lo que en esta investigación se propone un sistema de procesamiento de transacciones para aplicar compensación y marcha atrás en transacciones distribuidas de microservicios, ajena a la tecnología implementada y sin que afecte el rendimiento de los microservicios. Se propone y se implementa una arquitectura basada en el patrón de eventos, apalancándonos en la computación en la nube para disponibilidad los microservicios, el procesamiento de los eventos y la persistencia de datos. Esto con el fin de brindar una herramienta a los arquitectos y desarrolladores de software para resolver el problema de orquestar transacciones distribuidas a nivel de diferentes microservicios.
Understanding Islam: Positions of Knowledge, Bryan S. Turner (Edinburgh: Edinburgh University Press), 176 pages, ISBN 978-1474498746
Authors: Babacan Muhammed
Published: June 2023

İngiliz ve Avustralyalı bir sosyolog olan Bryan S. Turner, bu eserinde, bilginin içeriden ve dışarıdan gelen farklı konumlarını inceleyerek İslam’ı anlamayı amaçlar. Dine akılcılık bağlamında yaklaşan Turner, İslam dini hakkındaki tartışmasını hukuk (şeriat) veya dogmatik teoloji olarak ifade ettiği inançlar bağlamında değil, bir ‘deneyim dünyası’ (life-world) olarak adlandırdığı dini pratiklerin günlük yaşamda nasıl somutlaştığı ve yaşam biçimlerini ve kültürel değerleri nasıl etkilediği bağlamında yapar. Turner, Siyasal İslam, şeriat, Oryantalizm ve İslamofobi gibi temel konuları, pragmatizm ve postmodernizm gibi modern felsefeyle yapılan tartışmalar aracılığıyla keşfeder. Bilim ve nesnellik gibi geleneksel kavramlara bazı postmodern ve pragmatist itirazlar geliştiren Turner, dışarıdakilerin daha nesnel olabileceğine ve bir dinin veya kültürün içeridekiler tarafından görmezden gelinen veya ihmal edilen yönlerini fark edebileceğine inanmanın da mümkün olabileceğini tartışır. İslam’ı, özellikle, siyasi çatışma tarihi üzerinden anlamaya çalışır. ‘Siyasal İslam’ tabirinin aşağılayıcı bir şekilde kullanıldığının farkında olan Turner, Taliban ya da El Kaide gibi grupların eylemlerinin istisna olduğunu vurgulayarak okuyucuya Müslüman siyasetinin ve toplumsallığının birçok çeşidi olduğunu hatırlatır. Turner, özellikle Edward Said’in Oryantalizm tezine ve İslamofobi’nin sarih ampirik gerçekliklerine karşı olumsuz tutum geliştirir. Turner, her ne kadar İslam’ı anlamayı amaçlasa da kitabın birçok yerinde Hıristiyanlar ve Müslümanlar arasında diyalog yoluyla ortaya çıkabilecek bir anlayışın imkânını da arar. İslam’ın dışından biri olan Turner’ın içeridekilerin dünyasını anlamaya çalıştığı bu kitap, günümüz Müslüman toplumlarının sosyal ve siyasi meseleleri üzerine çalışan akademisyenlere ve genel okuyuculara kapsamlı ve önemli bir tartışma sunar.
El parlamentarismo difuminado español comparado con los modelos de parlamentarismo racionalizado
Authors: Ruiz Robledo Agustín
Published: June 2023

El sistema parlamentario se caracteriza porque el ejecutivo es elegido, controlado y cesado por el poder legislativo. El sistema parlamentario racionalizado es una variante de este sistema que juridifica las relaciones entre los dos poderes con un fin predeterminado: garantizar la estabilidad de los gobiernos frente a ocasionales mayorías negativas en los Parlamentos. Nace en la Europa de los turbulentos años veinte del siglo xx y se consolida, por toda la Europa democrática después de la Segunda Guerra Mundial, con multitud de reglas entre las que destaca la moción de censura constructiva, establecida por vez primera en la Constitución de Württemberg-Baden (1946). En España, la Constitución republicana de 1931 ya incluía algunas reglas de este parlamentarismo racionalizado, que se aumentaron y perfeccionaron en la Constitución de 1978, hasta el simbólico punto de invertir el orden en que aparecen los dos poderes en el título constitucional correspondiente: «De las relaciones entre el Gobierno y las Cortes Generales» (v). Si el texto constitucional ya basculaba a favor del Gobierno, la Constitución efectivamente vigente, su aplicación, lo ha hecho mucho más. Resalta especialmente que se ha hecho cotidiana la intrusión del Gobierno en la potestad legislativa —pensada para situaciones de «extraordinaria y urgente necesidad»—. La pandemia de COVID-19 ha reforzado esta tendencia, tal y como —Churchill dixit— sucedió en Gran Bretaña con la Primera Guerra Mundial.
El Patrimonio Nacional en el Parlamento. Una historia de la Transición
Authors: Sala Arquer José Manuel
Published: June 2023

En el contexto de la ingente obra legislativa de la Transición política española, la regulación del Patrimonio Real o Patrimonio de la Corona, hoy llamado Patrimonio Nacional, fue un mandato de la Constitución de 1978 que quedó relegado ante la necesidad de hacer frente a cuestiones políticas y económicas más acuciantes, y que sólo se abordó en el último momento, casi al final de la i legislatura de las Cortes Generales. La Ley de 16 de junio de 1982, que finalmente se aprobó, contó con el respaldo unánime de prácticamente todos los grupos del arco parlamentario.

La literatura científica se ha ocupado de este tema de forma monográfica en varias ocasiones. Con posterioridad a la Ley de 1982 existen varias publicaciones destacables, que analizan distintos aspectos del régimen jurídico de estos bienes. Falta, sin embargo, un trabajo que dé cuenta del proceso de elaboración y tramitación parlamentaria de la Ley de 1982. Es esta, efectivamente, una pequeña historia de nuestra Transición política que merece ser recuperada por muchas razones. El hecho de que fuese aprobada con un amplio consenso permitió dejar sentadas las bases del régimen jurídico de estos bienes para mucho tiempo, dejándolos fuera de los vaivenes políticos y las alternancias en el poder.

OO.) puedan personarse en un recurso de inconstitucionalidad como parte coadyuvante con base en lo dispuesto en los artículos 7, 10.2, 24 y 28 de la Constitución.
El estatuto jurídico de los parlamentarios y los requisitos de acceso al cargo
Authors: Lacambra Escobedo María
Published: June 2023

Las sentencias 148/2022 y 149/2022, ambas de 29 de noviembre de 2022 y dictadas por el Tribunal Constitucional, resuelven dos recursos de amparo planteados en el seno del proceso penal como consecuencia de los hechos acontecidos en España en relación con la comunidad autónoma de Cataluña que conllevaron la celebración del referéndum relativo a la independencia unilateral del territorio el 1 de octubre de 2017 y la aplicación del artículo 155 de la Constitución española. Dicho proceso penal se ha seguido contra los entonces dirigentes políticos de dicha comunidad autónoma y fue resuelto por la Sentencia del Tribunal Supremo, Sala 2.ª de lo Penal, de 14 de octubre de 2019.

En estas sentencias, el Tribunal Constitucional analiza el requisito manifestado por el acuerdo de la Junta Electoral Central de acatamiento presencial de la Constitución a efectos de la proclamación de candidatos electos al Parlamento Europeo, la emisión al Parlamento Europeo de suplicatorio de suspensión de la inmunidad de aquellos y la vulneración de diversos derechos fundamentales, relacionado con el artículo 23.2 de la Constitución.
