We Want Your Tools! Or Do We? On Digitized Cultural Heritage Archives And Commercial Content Identification Tools
Authors: Eriksson Maria
Published: September 2023

This article reflects on the technical gap that exists between academic and corporate capacities to study how digitized cultural heritage is reused online. In the context of tracing how audiovisual archival content is remixed and reinserted into new cultural contexts, the article asks what it would mean for humanistic researchers—and cultural heritage institutions more broadly—to utilize content identification tools provided by actors such as Google. How could commercial techniques for policing copyrights and tracing the whereabouts of online content be re-purposed to assist in research concerning remix practices and transformed culturalmemories? What technical and legal consequences would such partnerships yield? And would such collaborations be ethical and scientifically defendable in the first place? Ultimately, the article reflects on the legal and technical discrepancies that exist between academic and commercial actors when it comes to monitoring how cultural content moves online. It also asks questions about what it means to care for digitized heritage collections in the 21st century.

Authors: Alves Daniel Brito , Garcias Marcos de Oliveira , Campos Samuel Alex Coelho
Published: September 2023

Verificou-se de que forma está distribuída a infraestrutura nas escolas públicas de ensinos fundamental e/ou médio do Paraná e quais aspectos precisam de maior atenção dos formuladores de políticas públicas, uma vez que a infraestrutura escolar pode influenciar no desempenho dos alunos e, por conseguinte, no capital humano e no crescimento econômico. Utilizaram-se microdados do Censo Escolar de 2017 e 2019 e empregou-se a Análise Fatorial. Diante dos resultados, recomenda-se a implementação de políticas que visem a melhorias nas estruturas de apoio, atividades extraclasse e aparelhamento eletrônico. Constatou-se que escolas rurais ainda requerem maior atenção das políticas públicas e que, entre as mesorregiões, o Sudeste Paranaense carece de maior atenção quanto à infraestrutura de suas escolas.

Published: September 2023

Introducción: en Colombia son escasos los datos sobre el uso de los inhaladores en pacientes con EPOC. Objetivo: describir la técnica de uso de inhaladores de dosis medida y polvo seco en pacientes de un hospital colombiano. Materiales y métodos: estudio descriptivo en pacientes mayores de 40 años con EPOC atendidos en un hospital en La Virginia, Risaralda, Colombia, entre el 1 de septiembre de 2019 al 31 de enero de 2020. La unidad de análisis fueron los pacientes. Se incluyeron variables sociodemográficas, clínicas y lista de chequeo para uso de inhaladores. Se aplicaron frecuencias y proporciones para variables discretas, estadísticas de tendencia central y dispersión para variables continuas. Resultados: se incluyeron 104 pacientes con edad media de 73,6 ± 10,1 años; 57 eran mujeres (54,8 %). Además, 48 pacientes estaban clasificados como GOLD-D (46,2 %). Igualmente, 89 pacientes manifestaron haber recibido educación sobre el uso de broncodilatadores (85,6 %). Los más frecuentes fueron los inhaladores de dosis medida (DM) en 95 casos (91,3 %), seguido de los de polvo seco unidosis (7,7 %). Así mismo, 37 pacientes que usaron DM sin inhalocámara (35,6 %) no cumplieron los pasos de la lista de chequeo. En el sistema multidosis, el más realizado fue cerrar de manera adecuada el inhalador y el menos ejecutado, expulsar el aire lentamente evitando hacerlo cerca del inhalador (n = 6; 5,7 %). Discusión: se lograron describir las características de la técnica de uso de los inhaladores en pacientes con EPOC. A pesar de que ningún paciente logró utilizar el inhalador de forma “perfecta”, la mayoría han recibido educación por parte de los profesionales de la salud. Conclusión: un alto porcentaje de pacientes usa inadecuadamente los dispositivos para suministrar los broncodilatadores. Esto puede impactar negativamente en el control de la enfermedad.

In the pursuit of disseminating research findings, contributing to the collective body of knowledge and gain recognition, researchers are confronted with the pivotal decision of where to publish their work. While international journals attract attention for their global reach, legibility and impact factor, the significance of prioritizing publication in local journals need not be underestimated. This document aims to underscore the importance of embracing local journals as a priority in the realm of scholarly dissemination, emphasizing their unique contributions to scientific advancement, community engagement, and the holistic progression of research endeavors.
Formononetin enhances the chemosensitivity of triple negative breast cancer via BTB domain and CNC homolog 1-mediated mitophagy pathways
Authors: Li Shan , Zhu Linlian , He Yufeng , Sun Ting
Published: September 2023

This study aimed to investigate the effects of formononetin on triple negative breast cancer (TNBC). Clinical samples were collected from patients with TNBC. Overall survival rates were evaluated using the Kaplan-Meier method. Gene expression was determined using immunohistochemistry, immunofluorescence and western blot. Cellular functions were determined using CCK-8, colony formation and propidium iodide (PI) staining. Xenograft assay was performed to further verify the effects of formononetin (FM) on TNBC. We found that FM combined therapy suppressed the metastasis of TNBC and increased the overall survival rates of TNBC patients. Moreover, FM suppressed the proliferation and induced mitochondrial damage and apoptosis of TNBC cells. FM increased the expression of the BTB domain and CNC homolog 1 (BACH1) in TNBC tissues as well as cells. However, BACH1 knockdown antagonized the effects of FM and promoted the survival of TNBC cells. FM suppressed the tumor growth of TNBC. Taken together, FM suppressed the aggressiveness of TNBC via BACH1/p53 signaling. Therefore, FM may be an alternative strategy for TNBC.

Published: September 2023

The use of mining and metallurgical industry wastes containing calcium, magnesium, and strontium carbonates is described. The initial compositions and transformations occurring during the firing are considered. The best composition was chosen according to the results of laboratory studies, and based on that, ceramic brick was studied in real production conditions. The possibility of using mining and metallurgical industry wastes (dolomite and cake) as coloring pigments in the production of ceramic bricks has been theoretically substantiated and experimentally proven. Magnesium and strontium carbonates, along with calcium carbonates, participate in the formation of multicomponent systems, on the basis of which it is possible to obtain wall ceramics that meet modern requirements.

Mutual synchronization of oscillations in a system of coupled evolutionary games
Authors:   Lobachevsky State University of Nizhny Novgorod, Vershinina Olga , Ivanchenko Mihail ,   Lobachevsky State University of Nizhny Novgorod
Published: September 2023

The purpose of this study is to investigate collective dynamics of coupled communities that evolve according to the population game «Battle of the Sexes». A separate community includes two interacting populations of players of opposite sex, where each player has one of two possible competing behavior strategies. It is necessary to determine the possibility of mutual synchronization of oscillations in the number of players adhering to a particular strategy, build a synchronization region, and also evaluate the dependence of the properties of oscillations on the coupling strength. Methods. In this paper, we study the system of evolutionary games «Battle of the Sexes» interacting through migration. To simulate the evolutionary game dynamics we make use of the stochastic Moran process, as well as the Monte Carlo method to sample game trajectories. Mutual synchronization is defined by the appropriately generalized criteria of frequency and phase locking. Results. It is shown that the system of coupled evolutionary games «Battle of the Sexes» demonstrates mutual synchronization of oscillations under sufficiently strong coupling. In particular, oscillation frequencies of two communities get adjusted to each other and begin to coincide at some interaction parameter, while the oscillations themselves become almost identical. A similar result was also observed for an ensemble of more than two communities. Conclusion. The dependence of the average frequencies of community oscillations on the coupling strength was determined, the adjustment of oscillations with an increase in the coupling strength was demonstrated, thereby showing the possibility of mutual synchronization in the model of coupled evolutionary games «Battle of the Sexes». The region of frequency synchronization was numerically found.
Systemic risk in Russian financial market: A ΔCoVaR approach
Authors:   Saratov State University, Faizliev Alexey R.
Published: September 2023

Introduction. Recent financial crises have highlighted the need for increa sed attention to systemic risks and indicators to track them. This study is devoted to the assessment of systemic risk, which is a popular subject of economic research. The paper analyzes systemic risks in the Russian stock market for companies included in the RTS index. Theoretical analysis. We will focus on one common measure of systemic risk, CoVaR, which is the notional value at risk (notional VaR), defined as the change in the value of a financial system (asset) at risk versus another asset (system) in decline. The CoVaR risk measure is a powerful risk management tool and can be viewed as a simultaneous measure of system vulnerability, allowing the identification of assets that are classified as systemically important. Еmpirical analysis. The study tests the hypothesis of structural changes in the risk propagation network over time and looks at various measures of strength centrality, betweenness centrality, eigenvector centrality and Page Rank to identify assets that can propagate negative shocks through the network. Results. The results show that during the shocks of 2014 and 2020 the Russian stock market was exposed to more systemic risk and greater interconnectedness between assets. Shares of Sberbank and Tatneft contributed significantly to this risk during the political crisis and beyond, with company size not a dominant factor.

Published: September 2023

Introduction. The relevance of studying the industrial enterprise digitalization processes and developing a methodology for implementing production process control systems is due to the fact that digital technologies introduced into the manufacturing sector are important drivers for improving production management processes, improving labor productivity indicators, reducing the labor intensity of manufacturing products, reducing the cost of products and increasing quality. Theoretical analysis. The information systems and products most commonly used in modern practice of industrial enterprises in aviation industries are analyzed. Empirical analysis. The analysis of options for making managerial decisions to create an ERP complex that automates the processes of production’s technological preparation was carried out using the methods of analyzing advantages and disadvantages, paired comparisons and Kepner – Trego. A mechanism for making informed management decisions on the analysis of alternatives is presented, as well as the evaluation and selection of options for digitalization of the technological preparation processes based on the use of the principles of developing a management decision. Results. The choice of the Global ERP system for managing production preparation processes at industrial enterprises in the aircraft industry is justified, since it most closely matches the selected evaluation criteria.
Free use of someone else’s work for educational purposes: Some problems of legal regulation and law enforcement
Authors:   Saratov State University, Ilyukhina Yuliya Yu.
Published: September 2023

Introduction. Among the protected works of science, literature and art related to the results of creative work, there are objects that are significant from the point of view of the interests of society and can be tools for solving socially significant tasks, including those in the field of education. The general approach of the legislator to the legal regulation of such objects is aimed at ensuring their maximum accessibility to all interested parties. Maintaining a balance of private and public interests in the process of such regulation requires the use of effective legal means limiting the exclusive rights of the author. Theoretical analysis. Restrictions on the exclusive rights of the author are represented in civil law by the institute of free use of someone else’s work, which guarantees interested persons access to the use of other people’s intellectual activity results without the consent of the author and without payment of remuneration to him or her. Empirical analysis. In relation to educational activities, the law establishes two ways of using someone else’s work, which are permissible limitations of exclusive rights: quoting and illustrating. The normative acts do not disclose these terms, for their semantic analysis it is necessary to refer to the legal positions of the judicial authorities. The free use of someone else’s work is permissible subject to mandatory compliance with the set of conditions established in the norm, failure to fulfill any of which may lead to the recognition of the use as illegal. A number of rules establishing such conditions allow for significant flexibility in interpretation. Results. The specificity of the legal regulation of the free use of other people’s works for educational purposes lies in the evaluative nature of the key terms used by the legislator in the process of such regulation. For law enforcement, it would be advisable to use as clear and accurate a description of these definitions as possible.
Legal aspects of using information technology to compensate for physical disabilities
Authors:   International University “MITSO”, Vasilevich Dmitriy G.
Published: September 2023

Introduction. In the modern period there is a dynamic introduction of information technology in all spheres of social life. Scientific and applied achievements concerning the development of IT began to be actively used for the rehabilitation of people who became disabled, including those with problems with the musculoskeletal system, muscle atrophy, loss of hearing, vision, etc. Theoretical analysis. Advances in scientific and technological progress, especially in medicine, biomedicine, genetics, bioengineering, mathematics, programming, psychophysiology and neurophysiology, alongside the use of information and communication technologies, are changing the quality of life of people who find themselves in extreme health situations. The “industry of smart devices” is developing, assisting people in restoring the functions of lost organs. The use of “smart” devices raises the problem of ensuring free will and mental privacy, respect for privacy, which is one of the manifestations of individual freedom. In this regard, there is a need for the development of scientific directions that study the legal support for the implementation of neuro-interfaces and other “smart devices”. Results. Emphasis is placed on advances in biomedicine, psychophysiology and neurophysiology and other sciences, which, in interaction with the possibilities of information and communication technologies, contribute to the return of people with disabilities to active and fulfilling life activities. While using “smart” devices, there is a problem of ensuring free will and mental privacy, respect for privacy, which is one of the manifestations of individual freedom. It is emphasized that in the future there will be a need to resolve the dilemma between the benefits that “smart devices” can provide for people and the equality of people. The use of these devices in the absence of objective requirements may lead to inequality between people, creating advantages not conditioned by the natural qualities for some of them. The author puts forward an idea of the need to address the issue of qualification of the actions of those who hacked the neuro-interfaces, which caused death or additional harm to the person who uses it.
Calculating the amount of tax when using the simplified taxation system: Mathematical and statistical patterns of achieving a socially significant result
Authors:   Saratov State University, Konduktorov Anton S.
Published: September 2023

Introduction. The social orientation of legal regulation should be manifested in the process of performing any of the state functions, including the collection of taxes and fees. The balance of the “material interests” of the state and individual members of society when paying a mandatory payment is determined by the dynamics of variable economic indicators used in calculating its size. Within the framework of this work, the distribution of resources of a taxpayer applying a simplified taxation system between his or her employees and the budget (state) is investigated. Theoretical analysis. By means of mathematical constructions based on the normatively defined procedure for calculating the tax, an inversely proportional relationship between the amount of tax and the size of the payroll fund of employees of a taxpayer using a simplified taxation system is established. This effect was revealed regardless of the applied object of taxation. Graphic constructions illustrating the specified dependence are made. Empirical analysis. Based on the data of the Federal State Statistics Service, the correlation between the dynamics of gross domestic product and the dynamics of real accrued wages in the Russian Federation is studied. As a result, it was found that the growth rate of real accrued wages in the study period exceeded the growth rate of GDP. At the same time, however, there is a steady decrease in the difference between these values. Results. The systematic analysis of statistics allowed us to state that in the period under study, the socially oriented nature of the distribution of resources between the taxpayer’s employees and the state remains. However, the “orientation to the interests of the employee” is becoming less and less significant and, if current trends continue, the allocation of resources of a taxpayer using a simplified taxation system will soon be carried out more in the interests of the budget than of an employee.
The subject and procedure for consideration of cases of compliance of the initiative to hold a referendum on the proposed issue (proposed issues) of the referendum with the Constitution of the Russian Federation by the Constitutional Court of the Russian Federation
Authors:   Saratov State University, Sychev Vitalii B.
Published: September 2023

Introduction. The issue of the subject of review of cases of compliance of the initiative to hold a referendum on the proposed issue (proposed issues) of the referendum with the Constitution of the Russian Federation by the Constitutional Court of the Russian Federation is not regulated in the federal legislation. In addition, the federal legislation regulates the procedure for considering cases of this category only in general terms. Theoretical analysis. The systematization of the opinions presented in the scientific literature regarding the subject of verification in this category of cases allows us to distinguish two positions: the subject of consideration by the Constitutional Court should include both the issues proposed for a referendum and the entire procedure for the initiative of holding a referendum; only the issues proposed for a referendum should be the subject of consideration by the Constitutional Court. Empirical analysis. The analysis of the criteria (limits) of verification for the category of cases under consideration showed that, in any case, they should include compliance of the issues proposed for a referendum, the division of jurisdiction and powers between the state authorities of the Russian Federation and the state authorities of the constituent entities of the Russian Federation with the Constitution of the Russian Federation. The criteria for the admissibility of the motion, the procedural form and procedural periods of consideration of cases of the category under study need to be improved. Conclusions. The subject of verification in cases of the category under consideration should be not only the issues proposed for a referendum but also the entire procedure for the initiative of holding a referendum. The author proposes to amend the legislation providing for the exemption of the President of the Russian Federation from paying state duty when bringing the matter before the Constitutional Court of the Russian Federation in cases of the category in question, the possibility of participation of representatives of the electoral association or public authority proposing the initiative to hold a referendum, the Central Election Commission of the Russian Federation and the President of the Russian Federation in consideration of cases of this category. The author also proposes to provide a special chapter in the relevant law regulating the consideration of cases of compliance of the initiative to hold a referendum on the proposed issue (proposed issues) of the referendum with the Constitution of the Russian Federation.

Authors: Guesmi Mohamed Lakhder , Nafa Zahreddine , Bordjiba Abdelhak , Bouras Faouzi
Published: September 2023

This paper investigates the effects of burnt sawdust as an additive in asphaltic concrete, aiming to enhance the material's properties. The study sourced redwood sawdust from a carpentry workshop in Djelfa state, Algeria, and obtained bitumen, coarse aggregates, fine aggregates, and mineral filler from the Public Works Laboratory for the South in Ghardaïa state, Algeria. The sawdust was burned at 200°C in a furnace, cooled, and sieved through an 80 µm sieve. Standard procedures were employed to determine the material properties. Asphaltic concrete samples were then prepared with burnt sawdust at varying weight percentages of 0, 5, 15, 20, and 25% of the filler. The Marshall Stability test was conducted to assess the mixtures' stability, flow, density, voids filled with bitumen (VFB), air voids (AV), and voids in mineral aggregate (VMA). The results indicated an optimal sawdust content of 15%, showcasing improved properties when burnt sawdust was added to asphaltic concrete. Additionally, this utilization of sawdust contributes to preserving nonrenewable materials and reduces pollution from mineral filler manufacturing. Furthermore, the use of fine sawdust, typically considered waste, proves an environmentally responsible alternative to disposal.

"Głównym celem pracy była próba określenia możliwości generacji węglowodorów z poziomu łupku miedzionośnego na podstawie wyników badań pirolitycznych. W celu oceny materii organicznej 13 próbek rdzeniowych pochodzących z rejonu złóż rud miedzi w południowej części monokliny przedsudeckiej poddano badaniom pirolitycznym Rock-Eval. Dodatkowo próbki skalne badano również przy użyciu pirolizy wysokotemperaturowej sprzężonej z kapilarną chromatografią gazową (Py-GC/FID) i studiowano pod kątem zmienności trzech grup węglowodorowych: lekkich – C1–C9, ciekłych – C10–C15 oraz ciężkich – powyżej C15+. W przypadku każdej próbki została zastosowana jednoetapowa piroliza, prowadzona w programowanej temperaturze 500°C przez 0,4 min. Uzyskane wyniki były interpretowane kompleksowo i pozwoliły na rozróżnienie charakteru generowanych produktów na podstawie dystrybucji węglowodorów otrzymanych w wyniku pirolizy substancji organicznej zawartej w skale. Do określenia potencjalnych możliwości generacyjnych badanych łupków miedzionośnych wykorzystano zarówno udział procentowy poszczególnych frakcji, jak też bezwymiarowy wskaźnik uzysku (liczony z analizy Py-GC/FID). Na podstawie wyników badań pirolitycznych Rock-Eval oraz zbieżnych z nimi wartości wskaźników uzysku Py-GC/FID stwierdzono doskonały potencjał węglowodorowy dla wybranych próbek pochodzących z poziomu łupku miedzionośnego. Stopień dojrzałości substancji organicznej wyrażony poprzez parametr Tmax w przypadku większości badanych próbek z poziomu łupku miedzionośnego mieści się w zakresie okna ropnego, co potwierdziły również badania Py-GC/FID. Dodatkowo o możliwości generacji węglowodorów świadczy fakt występowania wysokiej zawartości ekstrahowalnej substancji organicznej oraz bardzo wysoka wartość parametru S2 (nawet do 41,88 mg HC/g skały). Analiza wyników badań geochemicznych pod kątem oceny potencjału generacyjnego poziomu łupku miedzionośnego udowodniła, że poziom ten nie powinien być pomijany jako potencjalnie macierzysty przy rozpatrywaniu źródła napełniania pułapek węglowodorów w systemie naftowym Niżu Polskiego."
Modelowanie pracy dubletu geotermalnego przy użyciu symulatora DARTS
Authors:   Instytut Nafty i Gazu – Państwowy Instytut Badawczy, Łętkowski Piotr
Published: September 2023

Na rynku funkcjonuje szereg narzędzi oferujących możliwości modelowania zjawisk przepływu masy i energii, wśród których można wymienić symulatory TOUGH, AD-GPRS czy Eclipse. W artykule przedstawiono wyniki modelowania pracy dubletu geotermalnego z wykorzystaniem symulatora DARTS, przy czym jako benchmark wykorzystano symulator Eclipse 100 z opcją TEMP, pozwalającą na modelowanie efektów temperaturowych w sytuacji zatłaczania zimnej wody do złoża. DARTS, który został zbudowany na uniwersytecie w Delft, jest stosunkowo nową propozycją na rynku narzędzi symulacyjnych, oferującą jednak szeroki zakres możliwości modelowania. W szczególności bardzo dokładnie modelowane są właściwości wody i pary, dla których korelacje charakterystyk termodynamicznych zbudowane są na podstawie IAPWS-IF97. Ponadto możliwe jest uruchamianie symulacji bazujących na siatkach nieregularnych (ang. unstructured grid) pozwalających na dowolne zagęszczanie siatki w zadanym obszarze. Symulator DARTS bazuje na nowej metodzie rozwiązywania nieliniowych równań przepływu – OBL (ang. operator-based linearization), która umożliwia skrócenie czasu obliczeń o około 1/5 (test na modelu składającym się ze 192 tys. bloków dla 500 kroków symulacji). Symulator DARTS, który jest rozpowszechniany na zasadach open source, zbudowano w języku wysokiego poziomu C++, lecz interfejs pozwalający na budowanie modeli został napisany w języku Python 3.9. Przeprowadzone na modelach analitycznych testy porównawcze wskazują na bardzo dobrą zgodność wyników uzyskiwanych przez wybrane symulatory. Błąd względny dla ciśnień dennych oraz wydajności wypływu wody dla odwiertów dubletu geotermalnego nie przekracza 1%, podczas gdy maksymalne różnice w rozkładach ciśnień i temperatur uzyskane w czasie testów zgodności nie przekraczają 2,5%. Istotną niedogodnością w stosowaniu DARTS jest brak dokumentacji oraz opisu technicznego, co powoduje, że pomimo szerokich możliwości modelowania zjawisk przepływu może on obecnie znaleźć zastosowanie bardziej w projektach badawczych niż komercyjnych.

Failures caused by offshore oil and gas structures operations are investigated. This work is based on the description and analysis of real case studies of accidents on offshore stationary and floating platforms; it combines foundational knowledge and current research on the latest developments in the field. It was shown that strength characteristics of offshore reinforced concrete and steel elements change during operation and cause the accumulation of defects and damages. It was established that corrosive wear, corrosion-mechanical processes, and crack-like defects are the decisive causes of element failure. It was shown that up to 60–75% of all damages to and failures of offshore engineering facilities' steel structures occur due to the corrosion-mechanical influence of an aggressive environment and force loads. This means that issues of corrosion-mechanical failure of such structures have become an industrial-scale problem. It thus allows us to draw the following conclusions: improvement of steel offshore drilling platforms (ODPs) maintenance system involves the development of new models and methods of managing the operational reliability of these structures, aimed at making decisions that take into account the crack resistance and fatigue-corrosion strength of steel ODPs in contact with the corrosive-active environment. Only on the basis of such scientifically and economically grounded models can rational strategies be shaped for carrying out revisions of the ODPs technical condition, ensuring the necessary level of their reliability during the operation period. This investigation can be very helpful to improve the design and construction of more reliable and durable offshore stationary and floating platforms.

Energia jest niezbędnym czynnikiem, który napędza wszystkie współczesne gospodarki. Według powszechnej opinii tradycyjne zasoby energetyczne, głównie paliwa kopalne, wyczerpują się, a ich użycie powoduje wzrost zanieczyszczenia środowiska naturalnego. Dlatego też na znaczeniu zyskują odnawialne źródła energii (OZE), które są neutralne dla otaczającego nas środowiska. Poprawa sytuacji energetycznej świata wymaga ukierunkowania na konieczność, a nie na opcję korzystania z zielonych nośników energii. Aby tak się stało, wymagane jest upowszechnianie odnawialnych źródeł energii oraz ich konkurencyjność ekonomiczna w porównaniu z pierwotnymi nośnikami energii, które w przyszłości ulegną wyczerpaniu. Warunkiem przeprowadzenia zielonej rewolucji jest eliminacja istotnych wad odnawialnych źródeł energii, takich jak: uzależnienie od zmienności warunków atmosferycznych, naturalna zmienność w cyklu rocznym oraz sprzyjające ukształtowanie terenu. Najbardziej perspektywicznym i stabilnym zielonym źródłem energii w naszych krajowych realiach jest biomasa, a dokładnie produkcja biogazu rolniczego z biomasy. Biogaz rolniczy i biogazownie rolnicze należą do najszybciej rozwijających się segmentów energetyki odnawialnej w Europie. W pierwszej części artykułu dokonano rozeznania literaturowego dotyczącego procesu wytwarzania biogazu, rodzajów biogazowni oraz surowców stosowanych do produkcji biogazu. Przedstawiono obecną sytuację rozwoju energetycznego rynku biogazu na każdym z kontynentów, poziom zróżnicowania pod względem liczby instalacji, stopnia ich skomplikowania oraz zastosowanych technologii i rozwiązań konstrukcyjnych, zwłaszcza w przypadku dużych, scentralizowanych biogazowni. Część doświadczalna obejmowała próby otrzymania surowego biogazu. W tym celu skonstruowano instalację umożliwiającą produkcję biogazu. Zastosowano surowce takie jak jabłka, marchew, trawę pochodzącą ze skoszenia terenów zielonych INiG – PIB oraz produkt uboczny powstający w procesie odśluzowania oleju rzepakowego. Na wyprodukowanych próbkach biogazu przeprowadzono porównawczą analizę intensywności pasm dwutlenku węgla do metanu FTIR, za pomocą której określono przybliżony udział tych dwóch składników. Na podstawie tej analizy wytypowano próbkę biogazu, który charakteryzował się największym udziałem metanu i dla którego wykonano pełną analizę składu gazu.

The article discusses the preparation and implementation of a complete comprehensive safety assessment of a hazardous production facility, such as environmental risk management, the risks of designing and operating enterprises, taking into account the human factor, engineering psychology, the development of labour protection management systems and other risks. When assessing risks when implementing various processes, for example, the transport support of offshore fields, it makes sense to prepare a comprehensive safety assessment of the individual operational structures. In this case, bow tie analysis is used to examine risk by demonstrating a range of possible causes and effects. The method should be applied in a situation where it is difficult to perform a complete fault tree analysis or where the research is more focused on creating barriers or controls for each failure path. The methodology for this analysis is the same as preparing and implementing an HSE for whole enterprise. The possibility to apply the Pareto principle to estimate technogenic risk parameters of composite systems was studied. According to the Pareto principle there are a few important parameters among many unimportant ones. Hence, the main success is achieved not by the many actions, but the few. This is applicable to a wide range of research areas, including manufacturing, economical and physical ones. In a bow tie diagram, some calculations may be applied for example, in a situation where the paths are independent and the probability of certain outcomes is known. Such a quantitative assessment is necessary to ensure the effectiveness of control.
Red-letter Reading Days: An eye-tracking perspective on Dr Seuss’ Green Eggs and Ham
Authors: Bergh Luna , Beelders Tanya
Published: September 2023

This article examines eye gaze while a multimodal text with vibrant and colourful images is read and furthermore specifically investigates the effect of the Stroop test on eye gaze. The Stroop colour-word test was designed to test the ability of a reader to suppress a habitual response. This particular variation of the test presented readers with words that refer to colour, but are presented in a different colour.

Results indicate images are used when unfamiliar objects are referred to and faces and characters attract attention. The use of incongruent colours definitely causes cognitive dissonance and negatively affect reading.
Slovene language from word to sign. An example of the use of the Slovene Sign Language in school
Authors: Kerman De Luisa Ana Elizabeta , Žele Andreja
Published: September 2023

Both language systems, spoken Slovene and Slovene Sign Language, are composed of basic word formation or sign formation elements, which act as cornerstones for compounded words and signs. The formation of new words in Slovene language is realised by adding suffixes after the base or stem of a word, linking together two or more bases with infixes, or adding prefixes before the base or stem of a word. To express these word formation types, sign formation adopts visual elements: facial expression, hand- and finger shape, signing speed, signing orientation and signing space.
The Implementation of Visual Grammar in Slovene Classes to Mother Tongue Speakers
Authors: Starc Sonja
Published: September 2023

The discussion focuses on the implementation of visual grammar in the study program for primary school teachers in the course Slovene language 1 - basics of text. It points out the theoretical premises of the Systemic Functional and Visual Grammar as the basis for discussing the multimodal texts, and along with a case study (34 student exam solutions) and findings from practice, presents the more challenging areas of student acquisition of theory and metalanguage. It justifies the need and shows the possibility of teaching multimodal textual analysis in school education.
Humour in Multimodal Textbooks for Slovene in Primary School
Authors: Rodela Martina
Published: September 2023

Research mostly establishes the benefits of humour in the learning process when used properly. We determine how primary school textbooks for Slovene as a mother tongue use verbal and pictorial semiotic resources to create humour when learning grammar, which resources are used more often, and how humour is perceived by pupils. Images are the main carrier of information in the creation of humour. An essential component of it is discrepancy with reality, most often expressed as exaggeration. For pupils aged 8 and 10, the involvement of humour is more important than for pupils aged 14.

The safety and economic feasibility of a coal-seam production is largely based on the stable operation of modern tunneling equipment. Identification of such heterogeneities of coal seam as sand down-cuttings and other is an important element of this. Information on the geometry of coal seams and their large-scale characteristics is often provided by a relatively dense network of exploration wells, however, these data are usually insufficient to identify such local features of the coal seam structure as down-cuttings. The present work shows the applicability of new method by means of wave field modeling. This method is based on focusing channel waves scattering on the seam heterogeneity. The result of applying the method is a medium image whereon an energy is focused at the combined point and at the point of the simulated scatterer. It is obvious that the practical applicability of the approach is based on the signal extraction against the background of intense surface noises and noise attenuation is supposed to be achieved through crosscorrelation processing.
