Blockchain in Agroecological Certifications: Innovation and the Challenges of Socio-Environmental Autonomy in the Face of Technological Colonization
Authors: Stroparo Telma Regina , Floriani Nicolas
Published: November 2024

Objective: This article explores the application of blockchain in agroecological certifications, through the theoretical framework of Socially Disruptive Technologies (SDTs), focusing particularly on technosocial disruption, examining how these innovations transform technical processes and the social and cultural dynamics involved.
 
Theoretical Framework: The theoretical foundation relies on Bruno Latour’s Actor-Network Theory (ANT), which considers technology as an active actor in socio-technical networks. In this context, blockchain is analyzed as a tool that can modify interactions among farmers, consumers, and certifiers. This perspective incorporates discussions proposed by Jürgen Habermas and Herbert Marcuse to explain the risks of technological colonization and instrumental rationality, which may occur when technologies like blockchain are implemented without regard for traditional knowledge and local practices.
 
Method: Using a qualitative approach and integrative literature review, the research addresses local governance and the risks of technological colonization through observation in rural communities.
 
Results and Discussion: The results suggest that the disruptive blockchain technology can promote greater transparency and traceability, yet it also presents challenges to the socio-environmental autonomy of rural communities. The social and cultural context of these communities needs to be respected, and blockchain implementation should promote participatory governance that values local knowledge.
 
Research Implications: This study discusses how the results may be applied or influence practices in the field of agroecology, highlighting the consequences for governance and local autonomy. These implications span areas such as participatory governance, the management of disruptive technologies in agricultural practices, and the preservation of socio-environmental autonomy in certification systems. The research proposes a hybrid governance model for the implementation of socially disruptive technologies, ensuring that they are used as support tools rather than as replacements for local practices.
 
Originality/Value: This study contributes to essential reflections on transformations occurring in agroecology by exploring the interaction between socially disruptive technologies (SDTs) and their interconnections with environmental autonomy. The research takes a critical perspective on the impacts of SDTs on the traditional practices and knowledge of rural communities. Additionally, it offers an approach that balances technological innovation and the preservation of sustainable practices, thereby promoting the ethical and inclusive use of emerging technologies in agroecological certification and production, serving as a reference for future policies and sustainability practices.

Published: November 2024

Aim. To study the antiviral activity of a soft medicine with mangiferin against the herpes simplex virus.
Materials and methods. The studies used samples of the soft dosage form developed with mangiferin, a xanthone belonging to the class of polyphenols. Mangiferin is a light yellow fine crystalline powder obtained from the leaves of the mango tree (Mangifera indica), (manufacturer Shaanxi, China). The substance contains 98.5 % of mangiferin.
The antiviral activity was studied on Vero kidney cells of an African green monkey obtained from the Cell Bank of the Institute of Experimental Pathology, Oncology and Radiobiology named after R. E. Kavetsky of the National Academy of Sciences of Ukraine. The cell cultivation was performed according to standard methods. The cultivation and accumulation of the virus was carried out on Vero cell culture. The infectious titer of the virus was 7.4 log10 TCD 50/ml. The MTT modification analysis was used to study the cell viability. The antiviral activity was studied according to standard methods. The virulicidal activity against HSV-1 was determined by decreasing the cytopathic effect of the virus on cells and the virus titer using the MTT method.
Results and discussion. The determination of the direct effect of the test sample on the extracellular herpes virus (virucidal effect) of an undiluted sample and samples in a dilution of 1:2.5 and 1:5 showed their ability to exhibit a significant virucidal effect against HSV-1 regardless of the dilution used and the exposure time with the virus. It was found that the decrease in the titer of the herpes virus was within 1.7-2.2 log10. When studying the ability of the test sample to influence the development of the cytopathic effect of the herpes virus on cells, it was determined that in dilutions (1:20-1:320), the sample inhibited the reproduction of the virus and the development of HSV-1 on Vero cells compared to the control virus. The greatest efficiency was found when using the sample in dilutions of 1:80-1:320; the reduction in the development of the cytopathic effect of the virus on cells was in the range of 59-64 %. When studying the infectious titer of the herpes virus synthesized de novo after the treatment with various dilutions of the test sample, it was shown that the test sample in the dilutions used did not significantly affect the synthesis of the infectious progeny of the virus, the decrease in the viral titer did not exceed 1.1 log10. Cytotoxicity assays showed that in the dilutions of 1:40 or more, the maximum reduction in cell viability was 18 %, indicating low toxicity of the sample.
Conclusions. According to the results of the study, the ability of the test sample containing 5 % mangiferin to effectively inactivate the extracellular herpes simplex virus Type 1 and significantly inhibit the development of the cytopathic effect of the virus on cells has been found.

Contextes comportementaux de l’émission sonore chez les Holocentridés : synthèse
Authors: Banse Marine
Published: November 2024

This synthesis addresses acoustic communication in holocentrid fishes, based on the combination of several recent findings from the author’s doctoral thesis and existing literature. To assist readers unfamiliar with the field of acoustic communication, the article begins with an overview of this fascinating discipline, accompanied by a brief introduction to the family Holocentridae. The manuscript then delves into the knowledge gained about the ethology of acoustic communication in this taxon and demonstrates how these research findings enrich this field of study. These results are the product of several months of research conducted in various regions around the world. An extensive data collection (sound and video recordings) was undertaken across the Indo-Pacific Ocean (Seychelles, Philippines, Guam, French Polynesia). These data document the behavioural contexts of sound production in several holocentrid species, based on about 77 hours of video recordings in the natural environment. Additionally, an experiment was conducted in aquariums to study the behavioural response, including sound production, of a holocentrid species to the introduction of a predator (e.g., a moray eel). The large number of species investigated in this research, along with the combination of data from both the natural environment and laboratory experiments, constitutes to my knowledge, the largest dataset on the ethology of sound production ever collected to understand acoustic communication in teleosts.
Development of an air quality indicator as a decision-making tool for urban development
Authors: Falzone Claudia
Published: November 2024

Au travers des Objectifs du Développement Durable (ODD) adoptés en 2015 par les Nations Unies, les villes ont mis au centre de leurs préoccupations la qualité de l’air lors de leur développement urbain. À l’heure actuelle, les outils à leur disposition pour l’évaluation de la qualité de l’air ne sont pas destinés à de la planification urbaine. Suite à ce constat, cette recherche propose de les outiller à l’aide d’un indicateur basé essentiellement sur des observations. Il présente un avantage en temps et en argent, car aucune mesure de polluant n’est nécessaire et les données sont disponibles librement. Cet indicateur, nommé Air Quality Observed Index (AQOI), pourrait être utilisé à des fins de comparaison de sites ou de projets lors de futurs développements urbains (rénovation ou nouvelle implantation). L’information sera relative à la qualité de l’air et fournirait aux autorités compétentes une aide dans leur prise de décision.

Methodological Approach to an Integrated Assessment of Systems for Remote Renewable Energy Supply
Authors: O.A. Baldynov , S.P. Popov
Published: November 2024

The use of renewable energy sources to reduce greenhouse gas emissions has become a global trend. According to forecasts of various international energy research organizations, this trend will persist in the future. As resources located near consumption centers are developed, the long-distance renewable energy transportation from areas where renewable sources operate with greater efficiency becomes a more pressing issue. Thus, the objective to establish an energy system using remote renewable sources arises. The study aims to elaborate a methodological approach for an integrated assessment of systems for energy supply from remote renewable energy sources. A distinctive feature of the proposed approach is a separate analysis of the main technological processes of production, conversion, storage, and use of energy carriers, with specific attention given to the generation of electricity from renewable energy sources. The Technique for order of preference by similarity to ideal solution (TOPSIS) is used for multi-criteria analysis of various solutions. This study aims to compare different energy systems for a project designed to export renewable energy from Russia (Sakhalin Island) to Japan (Yamagata Prefecture).

Authors: I.V. Filimonova , V.Y. Nemov , A.P. Samatova , N.G. Akopov
Published: November 2024

The paper applies machine learning methods to make projections of natural gas consumption volumes in China. It is critical for Russia as a major supplier of natural gas to China to have a reasonable estimate of possible volumes of exports. This contributes to the proper allocation of available raw materials, reduces the cost of excess gas storage, and also facilitates long-term planning for future trade. These aspects are critical for sustaining Russia's economic security and developing international economic relations. It is possible to estimate possible exports based on the projected volumes of natural gas consumption in China. This study uses machine learning methods, which are considered a promising data analysis tool, to model such consumption. We used multiple models for their benchmark comparison. Ridge regression was used as a linear model, whereas random forest and gradient boosting served as nonlinear models. The simulations performed proved gradient boosting to be the best choice. The study revealed the decisive role of socio-demographic factors, such as the population and the urban area size. The most significant factors were the total population, gas reserves, urban area size, number of passenger cars, and the population in urban agglomerations with over 1 million inhabitants.

Recent advances in the synthesis of graphene fragments that possess unpaired π-electrons and display high-spin ground states have unlocked possibilities to explore exotic physical phenomena related to magnetism. The high degree of spin-delocalisation makes these non-metal-based systems ideal building blocks for the construction of chains and lattices with strongly correlated magnetic ground states, which is the main requisite for measurement-based quantum computation. In this work, we demonstrate the magnetic bistability of a diradical nanographene that allows direct spin manipulation at the single-molecule level. To this end, we made use of solution-phase synthesis and tip-induced activation on a metallic surface to construct a helical non-Kekulé hydrocarbon spin switch, with a reversible transformation between a magnetic ground state and a non-magnetic one via intramolecular bond formation/breaking.

Photocatalytic proximity labelling has recently emerged as a powerful tool to resolve a wide variety of biomolecular and cellular interactions. While the use of high-resolution probe species, such as diazirines, enables cell-surface protein labelling with nanometre precision by generating highly reactive intermediates, intracellular applications are limited either by the intrinsic toxicity of frequently employed photocatalysts or lower resolution when long-lived reactive intermediates are used. In this work, we describe the discovery and application of an organic flavin cofactor derivative, deazaflavin, capable of diazirine activation to form carbenes through triplet energy transfer and offers unparalleled biocompatibility. We demonstrate deazaflavin-diazirine energy transfer labelling (DarT-labelling) not only allows for targeted extracellular scenarios using antibody conjugates but, most importantly, for intracellular interactome mapping of cellpenetrating peptides (CPPs). We successfully mapped the localisation of two popular polyarginine CPPs and identified potential key membrane interactors. Furthermore, we showed the applicability of DarT-labelling over extended time by mapping the intracellular trafficking of a stable cyclic derivative to reveal its eventual exocytosis from the cell. We envision DarT-labelling has the unmet potential to enable detailed profiling of intracellular dynamics across diverse biological systems with unprecedented spatiotemporal control.

We propel photopolymerizable liquid crystalline (LC) shape memory materials from solely elastomeric performance to the thermomechanical performance of tough, yielding thermosets. LC elastomers are at the forefront of smart, stimuli-responsive materials development. To apply their properties to mechanically superior thermosets, we demonstrate main-chain incorporation of high quantities of preordered LC motifs into a densely crosslinked network via thiol-ene photopolymerization to achieve a new material class hybridizing the advantages of LC elastomers and liquid crystalline networks. A terminal alkene mesogen with a robust LC phase is combined with multiple trithiol comonomers and selected based on resulting polymer crystallinities (13-37%). The bulk materials exhibit high strength, stiffness and pronounced yielding under stress with elongations around 200%. Their excellent thermomechanical properties were explained by phase separation observed in atomic force microscopy. Furthermore, we demonstrate shape memory of these materials with fast, near-perfect shape imprinting (99%) and recovery (97%) over at least 20 cycles, and their light-based 3D printing at high temperature.

Promiscuity, or selectivity on a spectrum, is an encoded feature in biomolecular anion recognition. To unravel the molecular drivers of promiscuous anion recognition, we have employed a comprehensive approach – spanning experiment and theory – with the Staphylococcus carnosus nitrate regulatory element A (ScNreA) as a model. Thermodynamic analysis reveals that ScNreA complexation with native nitrate and nitrite or non-native iodide is an exothermic process. Further deconvolution of the association and dissociation kinetics for each anion reveals that the release event can be limiting, in turn, giving rise to the observed selectivity: nitrate > iodide > nitrite. These conclusions are supplemented with molecular dynamics simulations that capture an entry and exit pathway coupled to subtle global protein motions unique to each anion. Taken together, our data point to how structural plasticity of the binding pocket controls the relative promiscuity of ScNreA to guarantee physiological nitrate sensing.
Trends and problems of higher education in Ukraine in contemporary conditions

Published: November 2024

The war in Ukraine, which began as a full-scale war on February 24, 2022, destroyed the usual rhythm of existence, led to severe destabilization in all areas of the country's life, disoriented the majority of the population, and raised questions about the search for ways to survive. Education is one of the most vulnerable areas of the socio-economic sphere. This is due, first of all, to the fact that it did not have time to fully recover after the stage of a difficult and protracted period of the global pandemic. Educational institutions were forced to significantly reform and adapt their work to the requirements of quarantine restrictions, conditions of limited communication in the educational institutions themselves and with students. These issues and tasks of guaranteeing safety, reliability, and accessibility of education in such life-threatening conditions were slowly resolved. However, this was only the first test for educators. The functioning of the education system in the conditions of war is an extremely difficult issue, because the preservation of the foundations of the state, its spiritual-mental, cultural, intellectual component depends on it.

The purpose of this article is to identify the leading trends and problems of the functioning of higher education in Ukraine. Based on the analysis of data received in response to a request for access to public information, in particular on the number of students in institutions of higher education of the I and II levels of accreditation, the number of students in institutions of higher education of the III and IV levels of accreditation, the teaching staff of higher education institutions, we established structural and dynamic features of higher education in large cities of Ukraine (for example, Kharkiv, Odesa, Dnipro and Lviv) during 2001-2021 as leading centers of higher education. The autrors revealed peculiarities of higher education in Ukraine in the conditions of the Covid-19 pandemic, the features and trends of the functioning of the higher education system in the conditions of a full-scale war and identified the existing problems, challenges, and opportunities for the further development of higher education.

A Study on the Mental Space of Subjunctive Mood
Authors: Zhan Haiying
Published: November 2024

Cognitive linguistics offers a novel approach to studying and elucidating language phenomena, with the theory of mental spaces being particularly adept at interpreting many “non-canonical” linguistic occurrences and providing a fresh cognitive framework. The subjunctive mood, one of the three primary moods in English, is integral to English grammar. Yet, it remains a contentious topic within the field, with a lack of consensus among different linguistic schools regarding this significant grammatical category. The substantial role of human cognition in the construction and interpretation of the subjunctive mood’s meaning has been infrequently explored. This paper, from a cognitive perspective, employs the theory of mental spaces to discuss the English subjunctive mood, addressing the questions of its theoretical foundation, the reasons for its use, and the methods of its application.

Authors: Zhu Xiaoyun
Published: November 2024

Leveraging the Baidu Qianfan model platform, this paper designs and implements a highly efficient and accurate scoring system for subjective questions, focusing primarily on questions in the field of computer network technology. The system enhances the foundational model by utilizing Qianfan’s training tools and integrating advanced techniques, such as supervised fine-tuning. In the data preparation phase, a comprehensive collection of subjective data related to computer network technology is gathered, cleaned, and labeled. During model training and evaluation, optimal hyperparameters and tuning strategies are applied, resulting in a model capable of scoring with high accuracy. Evaluation results demonstrate that the proposed model performs well across multiple dimensions—content, expression, and development scores—yielding results comparable to those of manual scoring.
