Keeping Elo alive: Evaluating and improving measurement properties of learning systems based on Elo ratings
Authors: Bolsinova Maria , Gergely Bence , Brinkhuis Matthieu J. S.
Published: July 2024

The Elo Rating System which originates from competitive chess has been widely utilised in large-scale online educational applications where it is used for on-the-fly estimation of ability, item calibration, and adaptivity. In this paper, we aim to critically analyse the shortcomings of the Elo rating system in an educational context, shedding light on its measurement properties and when these may fall short in precisely and reliably capturing student abilities and item difficulties. In a simulation study, we look at the asymptotic properties of the Elo rating system. Our results show that the Elo ratings are generally not unbiased and their variances are context-dependent. Furthermore, in scenarios where items are selected adaptively based on the current ratings and the item difficulties are updated alongside the student abilities, the variance of the ratings across items and students artificially increases over time and as a result, the ratings do not converge. We propose a solution to this problem which entails using two parallel chains of ratings which remove the dependence of item selection on the current errors in the ratings.

Authors: Hamal Koshal
Published: July 2024

The 'inter-art' refers to an artwork that is composed of more than one art form of the visual arts, such as sculpture, painting, video art, photography, ceramics, installation, performance, etc., showing the relationship between them. This study reveals the idea of inter-art relationships in the works of Gopal Kalapremi Shrestha, widely known as ‘Kalapremi’. The main objective of this paper is to explore the inter-art dynamics of Kalapremi’s artworks. The paper also aims to identify the key art genres in the creations of Kalapremi and to discuss the underlying meaning of his style. The paper reveals the importance of having multiple skills and techniques for an artist in today's contemporary art contexts. The effect of the inter-art relationship shows the dynamism, progressiveness, limitlessness, and unconventionality of an individual art practice. It mainly focuses on the inter-art relationship as a major tool to analyze creativity.

Published: July 2024

O presente artigo objetiva analisar a relação entre estudantes brasileiros e fronteiriços uruguaios nas escolas municipais de Jaguarão/RS. De acordo com as legislações vigentes, em cidades de fronteira gêmea, fronteiriços uruguaios, amparados pela Lei 13.445, de 24 de maio de 2017, são autorizados a estudar e trabalhar no país limítrofe. Ao longo do texto a fronteira entre Jaguarão e Rio Branco será vista como um local de encontros e desencontros que, embora seja vista como um território plural, a cultura nacional brasileira, em determinados espaços, padroniza e classifica determinados grupos como Outros, aqueles que não seguem os padrões sociais estabelecidos ou que pertencem a classes sociais, raças, culturas e etnias, tidas como inferiores. Metodologicamente adotamos uma perspectiva de estudo de caso, no qual, em um primeiro momento, analisaremos os documentos que regem a educação municipal de Jaguarão, através do seu Plano Municipal de Educação, em um segundo momento, apresentaremos algumas observações realizadas em três escolas municipais de Jaguarão e, em um terceiro momento, analisaremos tais observações, a fim de problematizar a relação entre brasileiros e fronteiriços uruguaios no contexto escolar. Por fim, analisar as escolas municipais de Jaguarão e olhar para os fronteiriços uruguaios enquanto sujeitos Outros dos Outros, abriu caminhos para pensarmos nas diferentes posições que ocupamos na sociedade e que estas não são fixas.
“O pove unide jamais será vencide”: metapragmáticas de violência linguístico-discursiva no X
Authors: Albuquerque Rodrigo , Lopes Gabriela Cristina de Souza
Published: July 2024

Considerando que as comunidades LGBTQIA+ testemunham recorrentes estratégias de deslegitimação quanto ao uso da linguagem não-binária em interações mediadas on-line que afetam não apenas a escrita, por si só, mas também ameaçam a própria existência, visamos analisar de que modo a ironia deslegitima o uso da linguagem não-binária e, portanto, constrói metapragmáticas de violência linguístico-discursiva no X (antigo Twitter). No âmbito teórico, aventamos um debate concernente às ideologias linguísticas, às metapragmáticas, à proxêmica linguístico-discursiva e à impolidez na formulação de um framework para o estudo da violência linguístico-discursiva entre os domínios da Sociolinguística Interacional e da Pragmática, inter-relacionando esse conjunto teórico às discussões na esfera da linguagem não-binária. No âmbito metodológico, apresentamos os procedimentos adotados nesta pesquisa, orientados por um enquadre netnográfico, crítico e, sobretudo, qualitativo, que envolvem a seleção de uma interação: uma thread e os comentários (em reação à thread) que abordam a relação entre a prova de redação do Enem e o emprego da linguagem não-binária. No âmbito analítico, evidenciamos que os/as interagentes usaram a ironia não só para deslegitimar o uso da linguagem não-binária na construção de metapragmáticas de violência linguístico-discursiva (interagentes A, B e E), mas também para legitimar tal uso (interagentes C e D). Reiteramos, por fim, ser primordial o desenvolvimento de uma consciência metapragmática para diagnosticar violências e, assim, referendar escolhas léxico-gramaticais não binárias que se alinham às constituições identitárias de pessoas igualmente não binárias.

Published: July 2024

O presente artigo objetiva averiguar a atuação da Comissão Interamericana de Direitos Humanos – CIDH no que diz respeito ao não reconhecimento de violações de direitos linguísticos, considerando as denúncias motivadas por os conflitos linguísticos nos países vinculados à Organização dos Estados Americanos – OEA, especificamente aquelas que foram identificadas nas publicações dos informes dos casos das inadmissibilidades da CIDH. Buscamos compreender a noção de direito linguístico humano com a qual opera a CIDH e, para tanto, procuramos demonstrar as possíveis transgressões denunciadas por minorias linguísticas contra Estados-membros da OEA, uma vez que a CIDH tem, entre suas funções, a de receber e analisar as denúncias para decidir se estas materializam violação de direito humano, resultando dessa análise a admissibilidade ou a inadmissibilidade da denúncia naquele foro. Para esta pesquisa foram analisados 695 (seissentos e noventa e cinco) casos através de informes publicados pela CIDH entre os anos de 1970 até 2022. As bases referenciais e conceituais usadas foram no presente estudo incluem as noções de Direito Linguístico de Abreu (2020); Sigales-Gonçalves (2020), a propositura da ideia de Conflito Linguístico de Daves e Dubinsky (2018), o conceito de conflito social de Honneth (2003), os pressupostos conceituais do campo das Políticas Linguísticas de Ricento (2006) e Severo (2020), bem como a ideia de minoria apresentada por Wucher (2000). Com as análises chegamos a um quantitativo de 16 (dezesseis) casos não admitidos relacionados às denúncias em que constam a possibilidade de violação de direitos linguísticos humanos.

Educação linguística racial: por um currículo de Língua Portuguesa descolonizado
Authors: Sampaio Alves de Sousa Rita de Cássia
Published: July 2024

O conhecimento da história, da cultura e da língua do povo negro é de extrema importância para compreender a constituição da sociedade brasileira assim como a construção do português brasileiro. No entanto, a história desse povo, assim como sua cultura e sua língua são negligenciadas na sociedade e nos sistemas formais de ensino, o que só demonstra o preconceito linguístico e racial – fruto de uma herança do colonialismo. Dessa forma, com base em autores como Nascimento (2019), Bagno (2016), Lucchesi (2015), Silveira (2020) e em leis e documentos como a BNCC, este trabalho tem como objetivo propor uma discussão sobre a importância de uma educação linguística racial de forma que questões que envolvam a história, a cultura e a língua do negro sejam trabalhadas de forma crítica e reflexiva no interior da escola. Para tanto, deixa-se em evidência a necessidade de ações que possibilitem uma descolonização do currículo.
Educação bilíngue de pessoas surdas e resistência em Deleuze e Guatarri
Authors: Pereira Daniane , Almeida Wolney Gomes
Published: July 2024

Esse texto visa discutir a educação bilíngue de pessoas surdas e sua resistência político-linguística, estabelecendo conexão entre a filosofia francesa, utilizando as ideias de Deleuze e Guatarri, no que diz respeito à ação conceitual e criativa da filosofia da diferença, através de pesquisa bibliográfica. Discussão relevante para a inclusão e valorização da diversidade linguística e cultural. No contexto da educação bilíngue de pessoas surdas, a resistência refere-se ao movimento e à luta para garantir o reconhecimento e a valorização da língua de sinais nas instituições educacionais. Historicamente, as pessoas surdas enfrentaram discriminação e marginalização na sociedade, e isso se refletiu também no campo da educação. A resistência surge como uma resposta a essas formas de exclusão e opressão. Os sujeitos surdos têm lutado por seus direitos linguísticos e educacionais, reivindicando o reconhecimento e o uso da língua de sinais como um direito fundamental. A resistência busca desafiar as práticas educacionais que priorizam a oralização e desconsideram a língua de sinais como meio de comunicação efetivo para as pessoas surdas. Busca garantir o acesso à educação inclusiva, que valorize a cultura surda, proporcione aquisição plena da língua de sinais e promova o desenvolvimento acadêmico e socioemocional dos estudantes surdos. Ao enfrentar as barreiras e desafios impostos pelo sistema educacional, a resistência tem como objetivo superar a visão deficitária da surdez, que considera a surdez como uma deficiência a ser corrigida, e reconhecer a língua de sinais como uma língua legítima e apropriada para a comunicação e o aprendizado das pessoas surdas.

The growth, development, and yield formation of winter bread wheat depends on renewal of vegetation date (RVD). This is one of the environmental factors most affecting the production process of plants. Purpose. To identify the peculiarities of the manifestation of biometric indicators in the genotypes of winter bread wheat at renewal of spring vegetation date in the conditions of the central Forest-Steppe of Ukraine. Methods: field, laboratory, statistical. Results. It was established that biocenosis formation of winter wheat at renewal of spring vegetation date significantly depended on growing conditions, sowing date, genotype and their interaction. Weather conditions were the dominant (25.2÷69.5%) significant for the influence. It was determined that after renewal of spring vegetation the influence of genotype (its ability to intensive growth and adequate response to changes in environmental conditions) and its interaction with the growing season conditions on all biometric indicators significantly increased. It was noted that under favorable hydrothermal regime, the level of realization of plant potential was maximum, while under conditions of soil and air drought it was minimum. This must be taken into account in breeding process, study of the source material, and selection of genotypes with specified parameters. The breeding line LUT 55198 had the highest biomass on average according to the experiment, which at the RVD formed phytocenosis with stem number per plant 2.60 pcs, leaf number per plant 7.74 pcs, plant height 16.51 cm, and plant weight 0.80 g. The level of variability in plant height was moderate (Cv = 14.08%) and for leave number, stem number, and plant weight it was significant (Cv = 18.39%; Cv = 21.54% and Cv = 29.89%, respectively).

Published: July 2024

The selection of the optimal scheme for the protection of sunflower crops is always relevant, since the protection of crops from weeds is very important and has a direct impact on the productivity of the crop. The goal is to determine the effect of soil herbicides on weediness of sunflower crops. Determining the effectiveness of various options for herbicide protection. Applied materials and methods: field experiment, laboratory, analysis, processing and generalization of data. The results of the application of different options of herbicide protection on the yield of sunflower of the right-bank forest-steppe of Ukraine are presented. It was determined that the experimental plots had a small-year type of weeding and an average degree of weeding. Among chemical protection, the best efficiency was recorded when using the soil herbicide Challenge at the rate of 5 l/ha, the efficiency compared to the control was 86.7%. It is worth noting that the efficiency of the reference herbicide Primekstra TZ Gold at the rate of 4.5 l/ha was 69.7%. The level of destruction of segetal vegetation on other variants of herbicide use ranged from 65.8% to 78.9% 14 days after application. The use of the drug Challenge at the rate of 2.5 l/ha in combination with Prometrex, Racer and Aspect Pro showed average efficiency and ranged from (61.0 to 55.3%). A decrease in the application rate of the drug Challenge - 2.5 l/ha in tank mixtures led to the growth of dicotyledonous weeds. It was established that the highest yield of 3.8 t/ha has the option of using the soil herbicide Challenge with a rate of 5.0 l/ha. In comparison with the control, an increase of 0.6 t/ha is recorded. A significantly lower level of sunflower productivity was obtained with the introduction of tank mixes Prometrex - 1.5 l/ha + Aspect Pro - 2.0 l/ha and Racer - 1.5 l/ha + Aspect Pro - 2.0 l/ha. A promising direction for further research is the study of the impact of herbicide protection on sunflower productivity and the effectiveness of segetal vegetation.

Authors: Kondratenko S. I. , Serhiienko O. V. , Marusyak A. O.
Published: July 2024

As a result of domestication, the created varieties and hybrids F1 of the cultivated form of eggplant (Solanum melongena L.) are characterized by low genetic variability and unsatisfactory adaptive potential for a set of quantitative traits useful for breeding and therefore require a significant renewal of the genetic plasma due to interspecific hybridization with other representatives of the Solanum genus. The goal is to create, for adaptive breeding, the starting material of a cultured form of eggplant (Solanum melongena L.) due to hybridization with a line of interspecies origin, derived from the fertile progeny of the hybrid F1(S. melongena / S. aethiopicum Gilo group). Methods: general scientific, measuring, weighting, variational statistics (calculation of root mean square deviation (σ), coefficient of variation (V)). Results. As a result of the hybridization of varieties and lines of the cultivated form of eggplant (Solanum melongena L.) with the line of interspecific origin BC2[F5 (Pavlotas-20 / Almaz variety)], the hybrid progeny F2 and the inbred progeny I1, derived from the hybrids F1, which according to the levels of manifestation quantitative traits valuable for breeding had a steady tendency to exceed the standard Almaz variety. The hybrid F2(BiboF8 / ВС2[F5(Pavlotas-20 / Almaz variety)]) (Xmed = 1101.8 g/plant) was highly productive. The high level of manifestation of the traits “number of fruits per plant” (Xmed = 5.56 pcs.) and “average weight of the fruit” (Xmed = 263.1 g) was noted by the hybrid F2(ВС2[F5(Pavlotas-20 / Almaz variety)] / BiboF8). Compared to the standard variety, the same F2 hybrid showed trait of early ripeness (by 2 days) in terms of the duration of the period from the appearance of mass seedlings to the technical ripeness of the fruits. In the studied sample of different eggplant progeny, those in which the coefficient of variation (V) did not exceed the limit of 33.33% already in the second year of breeding, which, according to the theory of statistical analysis, is a criterion of genetic stabilization of the corresponding quantitative trait at the level of the varietal population of plants. According to this criterion, samples F1 (Aisberh variety / ВС2[F5(Pavlotas-20 / Almaz variety)])I1 and F1(ВС2[F5(Pavlotas-20 / Almaz variety)] / BiboF8)I1, according to the trait “average fruit weight” – F2(Long Violet / ВС2[F5(Pavlotas-20 / Almaz variety)]), according to the trait “productivity of one plant” – F1(ВС2[F5(Pavlotas-20 / Almaz variety)] / BiboF8)I1. Discussion. Valuable genetic sources obtained on an interspecies basis will be involved in the breeding process of creating highly adaptive varieties and F1 hybrids of eggplant, suitable for organic growing technologies due to high abiotic resistance and the presence of genes for resistance to fungal diseases (Fusarium oxysporum f.sp. melongenae, Ralstonia solanacearum).

Published: July 2024

This article presents the results of the yield potential of Huberi and Himalaya wheat hybrids based on field research. A comparison of hybrids was carried out according to valuable economic characteristics. Research on the Huberi hybrid was conducted in 2014-2016, and the Himalaya hybrid in 2020-2022. Phenological observations of winter wheat crops and resistance to the main pathogens and pests were conducted according to generally accepted methods. As a result of the conducted research, it was established that the hybrids formed higher productivity indicators, compared to the standard, had higher indicators of grain quality, as well as resistance to biotic and abiotic factors. The Huberi wheat hybrid exceeds the average yields in all agro-climatic zones and is characterized by high winter hardiness, resistance to lodging and shedding of grain, as well as other important characteristics. The hybrid of the new generation of Himalaya stands out not only for its highest yield among all tested hybrids, but also for its high grain quality. This hybrid makes it possible to obtain grain of the highest class (A) with a high protein content. For the Himalayan hybrid, high resistance against the most common pathogens and stressful conditions in all growing zones was noted. The conducted research allows us to determine the advantages and disadvantages of each hybrid, as well as to identify the possibilities of using new hybrids to increase the productivity of wheat.

Published: July 2024

The relevance of this study lies in the need to determine the role of the autonomic nervous system in the metabolism of unsaturated fatty acids, especially essential ones, in the body of goats, which will improve the understanding of individual metabolic characteristics in these animals. The use of established blood markers will make it possible to analyse the state of lipid metabolism in the body of goats and ensure an increase in the effectiveness of methods of its correction. The purpose of this study was to determine the specific features of the autonomic nervous system influence on the relative content of unsaturated fatty acids in goat plasma lipids. The experiment involved goats of the Zaanenska breed, of which, using electrocardiographic analysis according to the Baevsky method and depending on the tone of the autonomic nervous system, three experimental groups were formed: normotonics, sympathotonics, and vagotonics. The method of gas-liquid chromatography was used to determine the percentage of unsaturated fatty acids in goat plasma lipids. Thus, in goats with sympathotonics, which have a predominance of sympathetic nervous system activity, a high percentage of the following lipids in blood plasma was noted: linolenic (P < 0.01), cis-4, 7, 10, 13, 16, 19-docosahexaenoic (P < 0.05), docosahexapentaenoic (P < 0.001), and arachidonic acids (P < 0.001) compared to normotonics. These animals also had a lower content of palmitoleic (P < 0.05) and oleic acids (P < 0.01) in plasma lipids against the background of normotonics. In vagotonic goats, in which the influence of the parasympathetic nervous system predominates, the relative content of cis-4, 7, 10, 13, 16, 19-docosahexaenoic (P < 0.05), linoleic (P < 0.001) and arachidonic acids (P < 0.001) and high cis11-eicosenoic acid (P < 0.01) in blood plasma lipids was found to be low compared to normotonic goats. The established features suggest a substantial influence of the tone of the autonomic nervous system on the quantitative redistribution of unsaturated fatty acids in the composition of goat blood plasma lipids and the need to consider them when analysing the state of the corresponding metabolism in the body, which will substantially improve not only the effectiveness of scientific research, but also its reliability

The relevance of this study is conditioned by the lack of detailed information on the structure and topography of the digestive organs of the Yemeni chameleon (Chamaeleo calyptratus). The purpose of this study was to find out the specific features of changes in body weight, topography, and structure of the digestive organs of the Yemeni chameleon, to determine their morphometric parameters in animals from 1 day to 1 year of age. The research material included the tongue, oesophagus, stomach, intestines, liver, and pancreas of chameleons of different sexes of 9 age groups. The data obtained were processed by one-factor analysis of variance (ANOVA). According to the topography, macroscopic structure and surface of the mucous membrane, there are three intestines in the small intestine: duodenum, jejunum, and ileum, and two intestines in the large intestine: the colon with a diverticulum and the rectum, which passes into the cloaca. A feature of the serous membrane of the chameleon intestine is that it is coloured black by melanin. From 1 day to 1 year of age, the body weight of chameleons increased 185.9 times, the snout-vent length (SVL) increased 6.7 times, the length of the digestive tract increased 3.8 times, and the ratio of the length of the digestive tract to SVL decreased from 3.2 to 1.8 times. The most intensive increase in body weight and SVL occurred during the second and third months of life. The relative length of the small intestine in chameleons of different age groups was 65.1- 81.6%, with the longest part being the jejunum. The increase in the morphometric parameters of the stomach, intestines, liver, and pancreas was asynchronous. The most pronounced changes in their relative weight were determined in animals of 2-3 months of age. The obtained materials supplement and clarify the information on the topography and structure of the digestive organs of the Yemeni chameleon, and therefore they will be useful in X-ray and ultrasound examination during veterinary manipulations
Thanatognomonic substantiation of the forensic veterinary diagnosis in the death of dogs and cats due to haemodynamic disorders and hypoxaemia
Authors: Kazantsev Roman , Yatsenko Ivan
Published: July 2024

At present, there are no legally consolidated, regulated procedures for conducting forensic veterinary examination of animal cadavers in Ukraine, which makes it difficult for law enforcement agencies to objectively qualify forms of administrative and criminal offences within the framework of pre-trial investigations. Therefore, scientifically sound research results in the field of animal treatment are of particular relevance. The purpose of this study was to substantiate the cause-and-effect relationships in the genesis of violent death of animals caused by mechanical injuries, thermal trauma, and mechanical asphyxiation with the identification of thanatognomonic patterns according to a two-level system of evidence. Methods of comprehensive forensic veterinary examination of animal cadavers were employed, followed by logical and epistemological processing of the results. It was argued that the main links of thanatogenesis in the case of death of animals from these species are irreversible haemodynamic disorders and acute hypoxemia. Based on this approach, an estimate of the area of pathological damage to internal organs incompatible with life is proposed, followed by an “expert hypothesis” regarding the determining cause of the animal’s death. The morphological positions of the forensic veterinary diagnosis in the form of thanatognomonic positions inherent in a certain subspecies of violent animal death were distinguished by two levels of evidence and their criterion informativeness was proved. Patterns of rapid death of animals of the first level of evidence common to the fatal consequences of mechanical and thermal trauma and mechanical asphyxiation were established: “asphyxiated heart”, congestive venous hyperaemia of internal organs, Tardieu’s spots, alveolar emphysema of the lungs. Patterns of the second level of evidence were selectively randomised and their species specificity was presented. The circumstances under which animals suffer fatal mechanical and thermal injuries and asphyxiation were detailed, and the mechanisms of death were substantiated. The study focused on the specific features of argumentation in concluding the necessary direct causal link between the genesis of violent death and the cause of death. The findings obtained following the standard of evidentiality “study of the object of forensic veterinary examination at different morphological levels” are recommended for implementation in the practice of forensic veterinary examination of animal cadavers

Published: July 2024

Road transport enterprises must constantly pay attention to increasing the efficiency of the production of quality transport services, in accordance with the requirements and expectations of consumers. During the production and provision of transport services, the flow of production processes in the transport system, problems often arise in the external and internal environment of the enterprise, which require a mandatory solution. The most common problems include the following: non-compliance of technical means with the requirements and expectations of service consumers in terms of the quality of passenger service, ensuring the necessary conditions for cargo transportation; significant negative impact of the transport process on the natural environment; not fully ensuring the safety of passenger transportation and ensuring the safety of traffic on the roads; imperfection of the system, methods, mechanism of planning and monitoring of transportation processes; imperfection of regulatory and legal regulation and control of the technical condition of vehicles in the organization of transportation; the level of driver training is not always sufficient.
When conducting research on the organization of transport processes and ensuring traffic safety on roads, the enterprise must use a methodical approach to evaluate the process of production of transport services, the functioning of the enterprise's production process, which must include three main stages: development of indicators and mechanisms for evaluating the flow of processes; assessment of the efficiency of the transportation process; analysis of assessment results and development of measures to improve service production processes. The main tasks of improving the processes of service production are the formation of the transport system of the enterprise, which includes: transport flows, personnel and technical support of transport, road environment in the transport zone. The transport system and all its constituent parts must be provided with means of monitoring and mechanisms of influence and improvement of the processes of production of transport services.
The process of improving the functioning of the enterprise's transport system should be conducted in three important directions: monitoring the transport process, studying and analysing the service market and taking into account the requirements and expectations of consumers, using calculation methods to determine negative impacts on the process and developing measures and mechanisms to prevent them.
Methodological basis of determination and control biofuels expenditure in the vehicle movement process
Authors: Ilchenko Andrii
Published: July 2024

The paper proposes a methodological approach to determine and control fuel consumption (biofuels) of a car that has known design parameters and moves in known conditions at known modes. It is noted that at this stage it is more attractive to use mixed fuels based on gasoline or diesel fuel with the addition of various impurities of biological origin. For gasoline-based fuels, impurities can be methyl or ethyl alcohol, for diesel fuel – vegetable oils, as well as their methyl and ethyl esters of these oils.
A structural and logical scheme has been developed, which explains the main provisions of the proposed determining method and controlling the biofuels consumption. In the structural and logical scheme, the following groups of parameters that take place during the car movement are highlighted: parameters of the conditions, the driving mode design. The mutual influence of parameters among themselves and between groups, the influence of the biological component concentration on its consumption, which must be taken into account to determine and control the consumption of biofuels during the movement of the car, was analyzed. It is shown that when switching to the use of biofuel, there is a change in the indicator coefficient of the internal combustion engine, which also affects the change in consumption.It has been proven that in the process of using biofuel, important factors affecting its consumption are density, lower heat of combustion, and the theoretically required amount of air for kg of biofuel combustion, which depends on the volumetric a specific biological component concentration in it.
It has been proven that in the biofuel use process, important factors affecting its consumption are density, lower heat of combustion and the theoretically necessary amount of air for combustion in 1 kg of biofuel, which depends on the volumetric a specific biological component concentration.
Taking into account the relative indicators of the «main» fuel (lower combustion heat, density and theoretically necessary air amount for the combustion of 1 kg impurities), it was established that the smallest increase in fuel consumption by the car engine during operation occurs when rapeseed oil is added to diesel fuel.

Authors: Kashkanov Andriy , Moskaliuk Mykola
Published: July 2024

The article formulates directions and analyzes the possibilities of substantiating and choosing the most optimal variant of applying mathematical models for forecasting the number and range of spare parts. The provided recommendations allow to take into account the multi-brand fleets of motor transport enterprises and trends for extrapolation in the short term, identified by the results of observations in real operating conditions.
The main reasons for the occurrence of prolonged vehicle downtime due to technical malfunctions are considered. Traditional methods of planning spare parts inventories based on the use of reliability theory and results of mileage forecasting, standard time to failure; inventory management theory and statistical methods for forecasting random processes; methods of operations research; economic and mathematical methods; stochastic methods of transformation of random variables are analyzed. The article formalizes the grouping of factors that affect the size of stocks and the range of spare parts in the operation of rolling stock of enterprises, depending on the state of the system of organization of work of services for maintenance and repair of vehicles; structure of the fleet and technical characteristics of vehicles; level of development of the production base; availability, interest and qualification of personnel; operating conditions of automotive equipment.
It is proposed to improve the logistics of spare parts inventory management and to formulate measures to improve the performance of carriers based on an assessment of the total costs incurred by the enterprise to maintain the reliability of rolling stock in operation and taking into account the amount of lost profit due to vehicle downtime in the technical service units. At the same time, it is recommended to use the mathematical apparatus of fuzzy set theory for decision-making, which allows formalizing the parameters of vaguely defined expectations of consumers of motor transport services and reducing the subjectivity of decision-making when solving problems of optimizing spare parts stocks in the transport process management system based on the analysis of the structure of consumer properties and service quality indicators.

Authors: Virk Nirmaljeet Kaur , Salman Syed Ahmed , Bhaumik Amiya
Published: July 2024

As technology advances, individuals have more significant opportunities to apply innovative technologies at work and in their daily lives, and education is no exception. As technology becomes an essential part of education, higher education institutions face challenges in integrating technology into the instructional and educational experience. As e-learning facilitates greater convenience, flexibility, and self-paced learning, existing models for predicting individual adoption of online education may be inadequate. Considering the continually evolving and pervasive developments in technology-based learning, the present study aims to analyze and expand the existing technology adoption theories. This article proposes a conceptual framework to highlight the role of mindfulness in making informed decisions about technology-based learning, as well as to integrate the notion into existing adoption theory. The expanded TAM is expected to outperform the original TAM in explaining actual behavior in online learning.
Rare simultaneous fetal posterior cerebral artery and conventional posterior cerebral artery duplication in a patient with a ruptured posterior communicating artery aneurysm: illustrative case
Authors: Ahmed Abrar A , Hatipoglu Majernik Gökce , Alvarado-Bolaño Alonso , Bres-Bullrich Maria , Pandey Sachin K
Published: July 2024

BACKGROUND

The fetal-type posterior cerebral artery (PCA) is defined as a variant anatomy in which the posterior communicating artery (PCOM) is larger than the hypoplastic or aplastic P1 segment of the PCA. The authors present the novel case of a patient with a duplicated right PCA in parallel with fetal-type and conventional PCAs supplying adjacent components of the PCA cerebral territory.

OBSERVATIONS

A 59-year-old woman presented with a modified Fisher Scale score 4 subarachnoid hemorrhage. A right irregular PCOM aneurysm that measured 9.5 mm × 4.5 mm × 4.5 mm arose from the base of a variant branch supplying a portion of the PCA, rather than a conventional PCOM, and was found on digital subtraction angiography. Following endovascular coil embolization, the patient was discharged home.

LESSONS

The fetal-type variant has implications for thromboembolic events. If an embolism occludes the anterior circulation in a patient with a fetal-type PCA, it may result in an infarct in the PCA territory. Awareness of cerebral arterial anatomy, including an atypical collateral supply, informs a treating team’s latitude in tolerance of which sites must be preserved and which can be safely sacrificed.
