Published: September 2024

Mangroves grow near the sea and inland. However, the mangroves that develop inland have a high and variable salinity. The salinity is a key factor in the anatomy of mangrove wood, this work aimed to show the impact of salinity on the vessel density, and the infradensity of Avicennia germinans (A. germinans). To do this, the trees of A. germinans were collected from the sites of Mamboumba (near the sea) and Oveng (inland), and analyses of vessel density and infradensity were performed in the laboratory. The results obtained show that the density of the vessels and the infradensity of heartwood, for example of A. germinans collected at the Oveng site are significantly higher with values of 38.11 ± 5.99 mm-2 and 0.95 ± 0.06 g/cm3 respectively compared to 28.75 ± 8.19 mm-2 and 0.81 ± 0.05 g/cm3 for A. germinans collected at the Mamboumba site. Also, we note that the vessels in Oveng wood are smaller than those in Mamboumba wood. This high salinity is responsible for the formation of small vessels and consequently for the increase in the infradensity of the A. germinans wood from the Oveng site.

Authors: Negrete-Moreno Daniela , Miller Annabel , Cieniewicz Elizabeth
Published: September 2024

Description: Potted tree experiments and detached leaf assays are used for many purposes, including: observing the effects of a single pathogen on a host cultivar, observing the effects of multiple pathogen interactions on a host cultivar comparing the defense responses and tolerance of different cultivars to pathogen attack. Abstract: South Carolina is the leading peach-producing state in the southeastern United States, where multiple pests and pathogens regularly threaten orchards. Here, we describe a methodology for controlled inoculations of potted peach trees or detached peach leaves with the bacteriumXanthomonas arboricolapv.pruni(Xap). This protocol is used primarily to study interactions between Xap and viruses in peach. To further understand the effects of a bacterial-viral co-infection, detached leaf assays serve as a controlled representation of what happens in the field. Hence, we report developing a Xap-specific spray inoculation method that inoculates a medium directly from bacterial colonies.

The Politics of Disconnective Media: Unraveling the Materiality of Discourses on Disconnectivity
Authors: Bozan Veysel , Treré Emiliano
Published: September 2024

The commodification of disconnection has attracted growing scholarly attention. Previous research highlighted the instrumentalisation of disconnection for productivity, self-governance, and healthy life. Researchers have also explored the politics of the “products” used for disconnecting, such as smartphone applications and offline commodities. Yet, current studies generally neglect to connect digital disconnection’s symbolic and material dimensions. In this article, we critically examine the discourses of what we call “disconnective media,” the products (hardware and software) that offer disconnection from digital devices. To explain how discourses and products find a basis in material and social structures, we deploy a discourse-theoretical analysis grounded in a Marxist materialist approach to neoliberalism and the materiality of discourse. We critically analyse six disconnective media and focus on these key dimensions: justifications (why to disconnect), time/space (when/where to disconnect), devices/platforms (which devices are appropriate to disconnect from), and class (who is addressed to disconnect). Findings show that digital technologies in the workplace have been naturalised, whereas phones and social media remain problematic. Leisure time is constructed with a set of obligations to use time meaningfully and improve the self, while work time is presented through a scientific work management mindset that promotes efficiency. Disconnective media advocate the ideal image of healthy, efficient workers. This study stresses the importance of investigating disconnection concerning commodified labour and neoliberalism’s material consequences.
Coping With Turbulence and Safeguarding Against Authoritarianism: Polycentric Governance as a Resilience Resource
Authors: Behnke Nathalie
Published: September 2024

Crisis management during the pandemic stimulated a bulk of analyses and debates on how states and societies coped with this challenge. In many countries, authority migrated temporarily from parliaments to executives and from the subnational to the national level, involving even violations of democratic and individual rights. Such reactions are motivated by the assumption that crisis management requires prompt, decisive, and uniform responses best delivered by a strong and centralised leadership. In contrast to this widespread assumption, crisis and disaster management research compellingly stresses the virtues of polycentric governance and processes based on flexibility, decentrality, and dispersed information in coping with turbulence. In this article, a framework is proposed for analysing empirically the question of what makes states and societies resilient. Core to this framework is the notion of resilience resources. In linking resilience resources to properties of socio-ecological systems and their reactions to turbulence, the resilience concept becomes accessible to empirical analyses. The potential of the framework is illustrated by an empirical example of the coordination of decentralised pandemic management by the German Minister-Presidents’ Conference. This example shows how the resilience resource of polycentric governance is put into practice. The results of the analytical, as well as the empirical part of the article, underpin the claim that resilience is fostered by coordinated decentrality, flexible adaptation, and bricolage instead of centralisation of authority. Fostering resilience in this sense provides also a safeguard against authoritarian tendencies.

Authors: Aleksandrov A. G. , Petrenko D. A.
Published: September 2024

Background. Diagnostics, treatment and rehabilitation of newborns with injury of the central nervous system (CNS) tissues are one of the pressing problems of contemporary medical community. Early diagnostics of hypoxic-ischemic damage to CNS tissues is a key element in the strategy of supporting newborns with asphyxia. The search for sensitive and specific diagnostic tools will improve the prognosis of disease outcome and the effectiveness of rehabilitation.

Objective: to identify promising serum biomarkers of brain tissue damage for screening and monitoring in neonates.

Material and methods. The search for publications was carried out automatically in scientific databases (PubMed/MEDLINE, Google Scholar, ScienceDirect) and electronic library (eLibrary) as well as manually in search engines (Yandex, Google). The subsequent selection of articles was carried out according to PRISMA recommendations. Of 3778 publications found, 52 were included in the review.

Results. The promising biomarkers of brain injury determined in the blood serum of newborns were detected: dipeptidyl peptidase 4, a number of cytokines, neuron-specific enolase (NSE), butylcarnitine, calcium-binding protein B S100 (S100B), F2-isoprostanes, nucleated erythrocytes, and some other biomarkers, the change in the level of which correlated with the severity of CNS tissue damage.

Conclusion. Blood-brain barrier dysfunction causes the appearance of highly specific proteins of neuronal and glial injury, in particular S100B and NSE, in blood serum, which can be determined as biomarkers. It is necessary to expand the evidence base and validation of using the mentioned biomarkers for subsequent implementation in clinical guidelines on managing patients with CNS tissue damage in the early postnatal period for timely diagnosis and correction of rehabilitation measures.

Published: September 2024

The paper explores Large Language Model (LLM) training on custom datasets for classification microservice development. As training general purpose models for every possible situation is not feasible on smaller scale, because of limitations of computation power, usage of smaller model architectures, such as NanoGPT for training LLM model for specific use-case is a more cost-effective solution. In this article the dataset “Internet Movie Database (IMDB)” is applied in the experiment for LLM training. The dataset IMDB contains user comments about movies. Training criteria was Cross-entropy Loss (CELoss) and Binary Cross-entropy Loss (BCELoss), which were compared in the experiment. LLM training showed that validation accuracy for CELoss is 85.84% while validation accuracy for BCELoss is 86.1%. The biggest difference was in the consistency of results as distance between minimal and maximal accuracy for CELoss was 2.36%, but BCELoss distance between minimal and maximal accuracy was 1.04% providing more stable accuracy.

Published: September 2024

BACKGROUND: The Russian Federation is among the top ten countries in terms of obesity prevalence among adults.
AIM: To identify the endogenous (biological factors such as age and FTO genotype) and exogenous (diet and physical activity level) factors that influence body fat accumulation and distribution among a group of women and men from Moscow.
MATERIAL AND METHODS: A total of 464 volunteers, consisting of 231 women and 233 men aged between 18 and 60 years, from Moscow took part in a single-center, cross-sectional, observational study. The program involved measuring body height, weight, body and limb girths, as well as conducting caliperometry, bioimpedance analysis, and administering questionnaires. Indices of body fat distribution were calculated. Additionally, differences in genotype, specifically the rs9939609 TA variant in the FTO gene, were also determined.
RESULTS: Maintaining a vegetarian diet for at least three years was associated with lower fat and fat-free mass, but not with abdominal fat in both men and women. Engaging in regular physical activity had the most significant impact on abdominal fat in both genders.
Furthermore, participating in amateur or professional sports activities for a minimum of 180 minutes per week was associated with lower overall body fat. We found no association between the FTO rs9939609 gene and fat accumulation or distribution, regardless of diet and physical activity levels.
CONCLUSION: The results suggest that vegetarian diet and regular physical activity are likely to be the most effective total and abdominal fat loss strategy for male and female adult residents of Moscow.

Published: September 2024

Introduction. The paper presents a reconsideration of the foundations of the discipline of Science Studies, taking into account post-non-classical ideas about science. This approach positions Science Studies not only as a scientific field but also as an educational discipline aimed at novice researchers. Aim. The present research aimed to assess the current state of science as a scientific and educational discipline in the Russian and Euro-American scientific traditions. It also aimed to present the project of teaching the discipline of Science Studies as a rigorous science, encompassing both its fundamental and applied aspects, and utilising quantitative and qualitative research methods. Methodology and research methods. The synthesis of universal evolutionism approaches (including deterministic chaos concepts) and the methods of quantitative and qualitative content analysis were employed. Results. A quantitative analysis of the state of science in Russia was conducted. The analysis revealed an increase in the interest of Russian researchers in scientific issues. However, it also highlighted a lack of clear understanding of its disciplinary parameters. Scientific novelty and practical significance. It is proved that Science Studies can be a significant incentive for the growth of scientific knowledge in Russia. The work has led to an understanding of the role of epistemological (cognitive) and social mechanisms in the development of science.
Mathematisation of specialised disciplines as the basis for fundamentalising IT training in universities
Authors: Perminov E. A. , Testov V. A.
Published: September 2024

Introduction. The widespread mass dissemination of digital technologies in all spheres of human activity places high demands on the quality of university students’ training in the field of IT. However, the quality of such training, and especially its fundamental nature, in many universities lags behind the requirements of the time. Additionally, a significant gap has emerged in higher education regarding the development of basic education curriculum for IT training. Aim. The present study aims to explore the potential of establishing the methodological foundation for the fundamental nature of education by incorporating mathematical principles into various specialised disciplines. This involves integrating discrete and continuous modelling principles and algorithmisation to create synergy. Results and scientific novelty. The synergy between discretion and continuity in mathematics, physics, and information processes is analysed. This analysis characterises the role of discrete mathematics in achieving a synergetic effect in teaching mathematics and computer science. It reveals the fundamental importance of mathematics in teaching formal modelling and algorithmisation languages. The significance of abstract algebra in the introductory teaching of formal languages at both school and university levels is justified. The significance of structures and algorithms, which are prevalent in discrete mathematics for training highly skilled programmers, is emphasised. Practical significance. The research findings will be of interest to both educational theorists and teachers, who provide IT training for students in various fields.

Published: September 2024

Introduction. Today higher education has become one of the spheres of active application of artificial intelligence (AI) systems capable of modelling human cognitive activity to solve various tasks. The possibility of independent application of AI tools by students and teachers has become a prerequisite for changing the model of educational process realisation. Aim. The study aimed to investigate the attitudes of teachers and students to the use of widely available artificial intelligence tools in education on the example of Tomsk State University (TSU). Methodology and research methods. The main research methods were sociological and statistical methods. A survey of students and teaching staff of TSU was conducted. The study sample was 1597 students and 250 teachers. To check statistically significant differences between subsamples by socio-demographic characteristics, the Pearson Chi-squared criterion was used, as well as the Z-test for comparing proportions (at a significance level of 95%, p < 0.05). A comparative analysis was carried out between the subsamples, as well as between the results obtained from students and teaching staff. Results. The results of the research showed that students are more likely than teachers to have a positive attitude towards AI tools. Teachers are more inclined to pay attention to the risks and negative factors that the integration of AI in education may entail. The respondents with experience in using AI are more positive about such tools in education. Undergraduate students are more optimistic about the prospects for the implementation and use of AI in higher education. Students who completed coursework assignments using AI-enabled tools noted that most of the time teachers did not notice it. Both teachers and students admit that AI tools can be used as information processing aides without compromising educational outcomes. Scientific novelty consists in identifying teaching staff and student attitudes towards AI tools in wide access: risks and opportunities of such tools in education. Practical significance. The data obtained and the results of the analysis allow recording a cross-section of the existing attitude of students and teaching staff to the opportunities for using artificial intelligence in higher education. It can become one of the bases for the development of principles and strategies for working with the subjects of the educational process on the possibilities of using new technologies with AI in their activities, in particular, through the creation of methodological recommendations, professional development courses for teaching staff, educational modules for students.

Authors: Aksenova N. I. , Usacheva O. V. , Chernyakov M. K.
Published: September 2024

Introduction. Today, there is no unified approach to understanding the main areas of digitalisation in education, its types, and elements. It is relevant to explore approaches to assess the state of digitalisation, reducing the subjectivity of assessments, and relying on objective data. Aim. The present research aimed to systematise and expand the areas subject to digitalisation in universities and to describe an algorithm for assessing the level of digitalisation using public information posted on university websites. Methodology and research methods. The main research methods involved morphological analysis, index, and matrix and score-rating methods. On the basis of the morphological matrix, the rating of a higher education institution was formed as an integral assessment, taking into account the weight values of its spheres. Results. The results of the research include the developed methodology for scoring and rating the assessment of the state of digitalisation in higher education institutions. This methodology encompasses four spheres of digitalisation: management and information security, organisation of the educational process, organisation of extracurricular activities, and profiling. Within these spheres, various types of digitalisation are identified, and elements are defined for each type. Higher education institutions in the Novosibirsk Region are ranked and grouped into clusters (six levels) based on the calculated integral assessment of their digitalisation level. Scientific novelty. The current research contributes to the development of a scientifically based approach to assessing the state of digitalisation in higher education institutions for comparative analysis using public information. The data obtained confirmed the necessity for further digital development to establish a comprehensive profile of a digital university. Practical significance. The practical significance of the results lies in the possibility of different groups of stakeholders (applicants, students, university management, and authorities) using the developed methodology to assess the state of university digitalisation and make various decisions, including managerial decisions.

Published: September 2024

Este artigo refere-se à investigação da própria prática no contexto de sala de aula, com a utilização de uma tarefa exploratório-investigativa, mediante a prática de discussão nas aulas de matemática. Nota-se que dada as demandas da vida escolar, como preencher formulário com o acompanhamento dos alunos, lista de chamada, dentre outras atividades, o professor, possivelmente, tende a perder o olhar crítico a sua conduta metodológica no ambiente de ensino e aprendizagem. À luz da problemática citada, a pesquisa foi realizada com alunos do 9º ano do Ensino Fundamental de um Colégio Estadual da região Norte do Paraná, no 2º semestre de 2018. Os   objetivos norteadores consistem em: (i) apresentar elementos reflexivos da professora-pesquisadora, com base em uma experiência de prática de discussão matemática; e  (ii) evidenciar aspectos do seu desenvolvimento profissional. A metodologia é de natureza qualitativa e centra-se em registros escritos dos alunos na resolução da tarefa, e da professora-pesquisadora em seu diário de campo, e, ainda, de gravações de áudio e imagem. Os resultados apontam para a importância de o professor pesquisar a sua própria prática, pois acaba por investigar sua atuação em sala de aula, suas metodologias de ensino, seus conhecimentos científicos e pedagógicos, podendo refletir e rever sua ação, atrelando o saber pedagógico ao saber da experiência. Esse resultado aponta para uma alternativa promissora em prol da formação do professor que atua na Educação Básica.

Authors: Oraibi F.H.
Published: September 2024

It was essential to investigate the features of overlapping nanocomposites because of the significance they have in the fields of science, industry, electricity, and medicine. As a result, it garnered a lot of attention and led a lot of scientists and researchers in the direction of studying the features of nanocomposite. Investigations have been conducted into the fabrication of (polystyrene (PS)-zinc oxide (ZnO)) nanocomposites and the examination of the optical characteristics of these nanocomposites for use in optoelectronic applications. Various concentrations for PS polymer & ZnO NPs were used in the fabrication of the nanocomposites using the solution casting process. The results of the experiments performed on (PS-ZnO) nanocomposites appear that each of the absorbance (A), absorption coefficient (α), extinction coefficient (K), refractive index (n), real and imaginary dielectric constants (εr & εi ), and optical conductivity (σopt) of polystyrene increase by increasing ZnO NPs concentrations. On other hand, the transmittance (T) and energy gap (Eg) decrease by increasing ZnO NPs concentrations. Nanocomposites made of zinc oxide have a high absorption in the ultraviolet spectrum.

Published: September 2024

Childhood uveitis is complex condition, and it is very rear in children compared to adults. It accounts for 5-10% of all uveitis seen in tertiary referral clinics. Prevalence of uveitis is 22 per 100,000 persons. Uveitis in children is commonly asymptomatic. It can become chronic and cause damage to ocular structure. Diagnosis can be delayed due to various reasons, including preverbal age and difficulties in examining young children. Uveitis morbidities in pediatric patients include cataract, glaucoma, and amblyopia. Close follow up is necessary as uveitis can flare up during immune-modulary therapy. Here, we represent an interesting case of uveitis in a 7 years old boy who had idiopathic uveitis and presented with red eye which is most common presentation in primary care.

Background: Empathy in healthcare, particularly therapeutic empathy, is vital for understanding and validating patients' emotions, leading to better patient care and outcomes. Despite its benefits, empathy often declines during medical training. While various training programs aim to enhance empathy are designed, there is a need for standardized methods and more qualitative research to address this. Therefore, in the current study, to enhance the combined concept of empathy and compassion, developmental interventions called "HR nurturing connects” (HRNC) were implemented.
Methods: This two-arm, prospective, randomized study involving 28 doctors. 14 doctors in the intervention group underwent the HRNC training which focused on enhancing empathy and compassion through training modules and constructive feedback. Whereas the control group received no developmental intervention. Evaluation for parameters of empathy and compassion were evaluated by using the cumulative Bhaktivedanta’s index of compassion and empathy in physicians and surgeons (BICEPS) score which involved assessments from doctors and 2 nurses, 2 ward clerks working with respective doctors at multiple time points.
Results: The intervention significantly increased empathy and compassion (p<0.001) of the doctors randomized in intervention group, with BICEPS scores rising from 66.51±3.87 (baseline) to 84.12±7.43 (12 months). In contrast, the control group showed minimal changes, with scores increasing from 63.48±4.56 (baseline) to 69.5±4.87 (12 months).
Conclusions: The ‘HRNC’ program has proven effective in enhancing empathy, compassion, kindness, and understanding in doctors, resulting in better patient outcomes, an improved workplace environment, and higher overall healthcare quality.

Gallstone ileus, a rare complication of cholelithiasis. This condition occurs when a large gallstone causes mechanical obstruction within the gastrointestinal (GI) tract, often due to a fistula between the gallbladder and the duodenum or stomach. Bouveret syndrome, a subset of gallstone ileus, involves gastric outlet obstruction caused by a gallstone. Here, we present the case of a 61-year-old female admitted with acute biliary pancreatitis, later diagnosed with gallstone ileus. Imaging revealed Rigler’s triad, and surgical intervention included an exploratory laparotomy, enterolithotomy, and staged management of a cholecystoenteric fistula. Despite successful surgery, the patient’s follow-up was limited due to voluntary discharge. This case highlights the complexity of gallstone ileus management and underscores the challenges in determining the optimal surgical approach, particularly in transient patient populations.
