Las mujeres y hombres a menudo comienzan sus carreras científicas con el mismo potencial, pero al final las mujeres investigadoras están subrepresentadas. Esto se debe a que las mujeres enfrentan retos y barreras en el camino que derivan en la deserción, y que a menudo se incrementa conforme avanzan en su carrera.

El objetivo del presente trabajo de investigación fue proponer alternativas para establecer modelos de financiamiento comunitario que permitan atender las necesidades financieras de las empresas del sector rural. Este tipo de empresas contribuye de manera importante al desarrollo de la región donde realizan sus actividades, regiones con ingresos más bajos generalmente. En México existen alrededor de 56,700 organizaciones rurales que realizan principalmente actividades en el sector agrícola, donde los esquemas de crédito vigentes no tienen la misma accesibilidad para ellas, debido a diferentes factores como tasas de interés altas, requisitos complejos y falta de garantías. El trabajo realizado fue del tipo documental descriptivo, lo cual implicó la recolección, selección, análisis y presentación de la información para conocer el alcance que han tenido las fuentes de financiamiento disponibles para las empresas en el medio rural. Los esfuerzos realizados por el Estado con Fideicomisos Instituidos con Relación a la Agricultura (FIRA) y la Financiera Nacional de Desarrollo Agropecuario, Rural, Forestal y Pesquero (FND) para la inclusión financiera ampliando sus programas y cobertura, han tenido resultados.

3D concrete printing (3DCP) is one of the most important priorities for the development of the construction industry around the world. Despite optimistic forecasts for the growth of additive construction technology in the long term, there are various risks that can influence the pace of this development, which are associated, first of all, with the need to develop the regulatory framework, train qualified personnel, create and improve equipment and materials for 3DCP – seal. There is a lot of research aimed at creating and developing the scientific basis for the design of concrete for construction 3D printing; compositions of dry mortars for additive manufacturing based on mineral binders, mainly cement, have been proposed; much less attention is paid to composites based on gypsum and mixed – gypsum-cement-pozzolan binders (GCPB). The purpose of this work is to study the structure and properties of fine-grained concrete for 3DCP based on gypsum-cement-pozzolan dry mortars. The molding of samples during experimental studies was carried out using the layer-by-layer extrusion method on a workshop construction 3D printer “AMT S-6044”. The rationality of using concrete with a ratio of GCPB:aggregate = 1:2 in the additive manufacturing technology with a sand fineness modulus of Mk 3 has been substantiated. A composition of gypsum-cement-pozzolanic concrete (GCPC) modified with a multifunctional complex additive has been developed, which allows increasing the compressive strength by 35.3%, water resistance – by 73% (up to 0.85) compared to the control unmodified composition. It has been established that modification of GCPB with the developed multifunctional complex additive leads to a decrease in the volume of open capillary pores by 20.5%, the volume of open non-capillary pores – by 66.7%, an increase in the volume of conditionally closed pores by 28.1%, and the microporosity index – from 0.22 to 0.89. The synergistic interaction of chemical additives in complex additive composition is confirmed by the results of studies performed to determine the electrokinetic potential on the surface of GCPB particles and the kinetics of heat release during its hydration.

Published: August 2024

The influence of highly dispersed tungsten-containing powders (WC, WO3, a mixture of WC, TiC) obtained as a result of recycling of carbide products on change in the structural and physico-mechanical properties of cement materials at elevated temperatures has been studied. Powders of tungsten carbide WC, tungsten oxide WO3, mixtures of tungsten and titanium carbides WC, TiC (average particle size 20–150 nm, agglomerates 300 nm – 1.5 microns) were added to the cement mortar, by partial replacement of the binder, in various concentrations (1–5 wt. %). The effect of additives on the thermal stability of cement samples was assessed by weight loss, residual compressive strength, exposed to temperatures at 300, 600 and 800оC for 2 hours. The microstructural analysis was performed using scanning electron microscopy (SEM) with an integrated energy dispersion analysis system. It was established that in the entire temperature range under consideration (20–800оC), the modified samples demonstrate a denser microstructure, have less mass loss and have increased residual compressive strength compared with the control composition. The obtained research results are of considerable value for understanding the mechanisms of influence of highly dispersed tungsten-containing particles on the characteristics of cement materials under high-temperature exposure.

Introducción: dada la creciente prevalencia del consumo de cannabis en adolescentes y su impacto en la salud mental, surge la necesidad de detectar a aquellos individuos más susceptibles a sus efectos perjudiciales. La reserva cognitiva (RC), es la capacidad del cerebro para hacer frente al daño cerebral sin manifestar síntomas de deterioro. Este enfoque resulta especialmente interesante para identificar individuos susceptibles durante etapas de vulnerabilidad, como la adolescencia. Objetivos: describir el protocolo del estudio y los resultados preliminares, resultado de evaluar la RC en una muestra de adolescentes con diagnóstico de trastorno por consumo de cannabis, así como su influencia en la psicopatología, funcionamiento y rendimiento cognitivo. Material y métodos: estudio transversal y observacional, que utiliza escalas clínicas. Se emplearon la prueba de Chi cuadrado para variables categóricas relacionadas con el consumo de cannabis, la prueba de U de Mann-Whitney para variables cuantitativas como la severidad del trastorno, y la prueba de Rho de Spearman para explorar correlaciones. Resultados: se incluyeron 12 participantes, 58,33% chicas, con 16,5 ± 1 años. La mayoría de la muestra se ubicó en el grupo de baja RC (90 %) y con casi un 50% de bajo funcionamiento. Se observó una asociación entre bajo funcionamiento global y sintomatología psicótica positiva, maníaca, gravedad clínica global y peor adherencia a la dieta mediterránea. Conclusiones: en la muestra preliminar se observa una importante baja RC en adolescentes con trastorno por consumo de cannabis. Identificar individuos con baja RC y riesgo de psicopatología podría dirigir programas preventivos y terapéuticos más efectivos y precisos.
Sex-Selective Infanticide and Sociality in Brown Bear Populations
Authors: Puchkovskiy S. V.
Published: August 2024

An analytical review of scientific publications containing materials or discussion of the concept of sexually selective infanticide (SSI) in brown bear populations (Ursus arctos) is presented. The authors of the SSI concept refer to the idea of sexual selection, which is a rather shaky conceptual basis. The concept was formed largely on the basis of materials obtained during the study of intraspecific relations in lion populations (Panthera leo). However, the facts from the behavioral ecology of the lion, which accumulate relatively quickly, can be interpreted quite ambiguously and even only when applied to this species, the concept of this does not look convincing enough and is obviously unnecessarily anthropomorphic. Infanticide, cannibalism and their combination are recorded in both lion and brown bear populations. However, the behavioral ecology of these species differs significantly. Brown bear populations are characterized by: pronounced seasonality of reproduction; the presence of a reproductive interval in bear females, which can vary significantly in populations with different habitat conditions and varies from 1 to 5 years; mating patterns can vary from lax monogamy to panmixia. Multiple paternity is possible within the litter (single fertility) of a brown bear. It follows from the review that brown bear populations are characterized by many features of sociality, the lifestyle of bears being both solitary and group. It is hardly correct to classify the brown bear (and other species of bears) as uniquely unsocial. From the analysis of publications on the behavioral ecology of the brown bear, it follows that the application of the SSI concept without significant additions is hardly useful for understanding the intraspecific relations of this species.

This review summarizes information on the main negative factors affecting the state of floodplain water bodies ecosystems, describes the most common consequences for abiotic and biotic processes, and suggests possible ways to conserve these ecosystems. Evidence of the negative impact of hydraulic construction, embanking of floodplains, channelizing of rivers, agriculture, and other anthropogenic impacts is presented. A special role is played by climate change, which leads to a decrease in flood inundation, drying and overgrowing of water bodies, and their eutrophication. The authors suggest criteria to choose correct indicators that can testify not only to special stages of water body succession (e.g., vegetation) or its trophic status (zooplankton), but also to the long-term effects of anthropogenic and climatic changes. As a recommendation, it is proposed not to consider water bodies separately, but to assess the whole waterscapes and use the change in β-diversity as an indicator. Further conservation strategies can be based on the approaches of the Red List of Ecosystems of the International Union for Conservation of Nature and Natural Resources (IUCN), which will help to draw attention to the problem. The key role for the conservation of floodplain water bodies should be played by territorial protection measures, up to the development of a separate category for small water bodies.
Внутренние давления адсорбата в мезопорах разной геометрии и вопросы анализа механизмов его течения
Authors: Зайцева E. S. , Товбин Ю. К.
Published: August 2024

Проведен анализ молекулярных однофазных распределений внутри щелевидной и цилиндрических пор с однородными стенками в широком диапазоне давлений и температур, когда в них находятся жидкость или пар. Стенки пор считаются недеформируемыми, они формируют внешнее поле для флюида. Состояние фаз “жидкость в поре” и “пар в поре” удовлетворяет равенству химического потенциала с химпотенциалом объемной фазы. Расчет распределений молекул проведен в рамках модели решеточного газа (МРГ) с простейшим парным потенциалом взаимодействия ближайших соседей. Распределение плотности молекул в неоднородном поле стенок пор связано с локальными распределениями двух видов давлений: изотермического, связанного с химпотенциалом системы, и внутреннего механического давления (или давление расширения в терминах МРГ). Разность каждого из двух видов давлений с соответствующим давлением в объемной фазе определяет расклинивающее давление, которое активно используется при термодинамической интерпретации характеристик тонких прослоек в зависимости от их ширины. Получено, что оба вида расклинивающих давлений в щелевидных и цилиндрических порах пропорциональны друг другу. Коэффициент пропорциональности зависит от параметра потенциала взаимодействия адсорбент – адсорбат и его протяженности, геометрии поры, температуры, а также зависит от ширины цилиндрических пор, но не зависит от ширины щелевидных пор. Размерные производные двух видов расклинивающего давления от ширины поры, через которые выражаются потоки адсорбата, также связаны между собой теми же коэффициентами пропорциональности.

Проведен сравнительный анализ состава и структуры свежеосажденных осадков гидроксида железа(III), полученных из раствора сульфата железа(II) в присутствии сульфата натрия (400 мг/л) при рН 7 и 8 до и после сорбции на них ионов никеля. Методами ИК- и КР-спектроскопии, рентгенофазового и термогравиметрического анализов показано, что осадки имеют брутто-формулу Fe2O3 × 2H₂O и содержат небольшое количество гетита (α-FeOOH) и лепидокрокита (γ-FeOOH). Установлено, что сорбция ионов никеля на этих осадках не сопровождается хемосорбцией, т.е. образованием смешанных соединений между железом и никелем. Дзета-потенциал частиц осадков при рН 6 имеет положительное значение, а при рН 6 становится отрицательным. Точка нулевого заряда частиц осадков соответствует рН = 6.

Published: August 2024

A study was carried out to identify the influence of the size of the cycloalkenyl ring and the nature of the substituent at the nitrogen atom on the structure and stability of the halogen cyclization products N-acyl-N-(2-cyclopent-1-en-1-yl-6-methylphenyl)glycines, which were synthesized from N-acyl-2-(1-cyclopenten-1-yl)-6-methylanilines and methyl bromoacetate followed by alkaline hydrolysis of the resulting methyl glycinates. It was shown that in the reaction of N-benzoyl and N-(4-nitrobenzoyl) derivatives with molecular bromine, 2′-bromo-9-methyl-N-aroyl-1,2-dihydro-3H-spiro[4,1-benzoxazepine-5,1′-cyclopentan]-3-ones and 8-methyl-N-aroyl-3,3a,6,7- tetrahydrobenzo[e]cyclopenta[g][1,4]oxazocin-5(2H)-ones is formed, the ratio of which in the case of the N-benzoyl derivative is ≈1:4, in the case of the N-nitrobenzoyl analogue reaches ≈1:1. Spiro-fused benzoxazepinones, unlike eight-membered heterocycles, are unstable. Samples of these compounds isolated by chromatography decompose with strong darkening within a few hours. In the case of the N-acetyl homologue, the resulting halogenlactonization products cannot be isolated due to their rapid decomposition. The aS*,R*-configuration of the substituents along the N⁷–C⁷a axis and at C³a center of chirality of N-aroylbenzoxazocinones was established by X-ray diffraction studies.
A REDOX-REGULATED, HETERODIMERIC NADH:CINNAMATE REDUCTASE IN Vibrio ruber

Published: August 2024

Genes of putative reductases of α,β-unsaturated carboxylic acids are abundant among anaerobic and facultatively anaerobic microorganisms, yet substrate specificity has been experimentally verified for few encoded proteins. Here, we co-produced in Escherichia coli a heterodimeric protein of the facultatively anaerobic marine bacterium Vibrio ruber (GenBank SJN56019 and SJN56021; annotated as NADPH azoreductase and urocanate reductase, respectively) with Vibrio cholerae flavin transferase. The isolated protein (named Crd) consists of the sjn56021-encoded subunit CrdB (NADH:flavin, FAD binding 2, and FMN bind domains) and an additional subunit CrdA (SJN56019, a single NADH:flavin domain) that interact via their NADH:flavin domains (Alphafold2 prediction). Each domain contains a flavin group (three FMNs and one FAD in total), one of the FMN groups being linked covalently by the flavin transferase. Crd readily reduces cinnamate, p-coumarate, caffeate, and ferulate under anaerobic conditions with NADH or methyl viologen as the electron donor, is moderately active against acrylate and practically inactive against urocanate and fumarate. Cinnamates induced Crd synthesis in V. ruber cells grown aerobically or anaerobically. The Crd-catalyzed reduction started by NADH demonstrated a time lag of several minutes, suggesting a redox regulation of the enzyme activity. The oxidized enzyme is inactive, which apparently prevents production of reactive oxygen species under aerobic conditions. Our findings identify Crd as a regulated NADH-dependent cinnamate reductase, apparently protecting V. ruber from (hydroxy)cinnamate poisoning.

This paper presents new structural data about mitochondria using correlative light and electron microscopy and cryo-electron tomography (cryo-ET). These state-of-the-art structural biology methods allow the study of biological objects at nanometer scales in natural conditions. The non-invasiveness of these methods makes them comparable to observing animals in their natural environment on a safari. The paper highlights two areas of research that can only be accomplished using these methods. The study visualized the location of Aβ42 amyloid aggregates in relation to mitochondria to test a hypothesis for the development of mitochondrial dysfunction in Alzheimer’s disease. The results showed that Aβ42 aggregates do not interact with mitochondria, although some of them are closely located. Therefore, the study demonstrated that mitochondrial dysfunction is not directly influenced by aggregates on mitochondrial structure. The source of mitochondrial dysfunction should be investigated in other processes. Second unique area presented in this work is the high-resolution visualization of mitochondrial membranes and proteins in them. The analysis of cryo-ET data reveals toroidal holes in the lamellar structures of cardiac mitochondrial cristae, where ATP synthases are located. The study proposes a new mechanism for sorting and clustering protein complexes in the membrane based on topology. According to this mechanism, the position of oxidative phosohorylation system proteins in the membrane is determined by its curvature. High-resolution tomography expands and complements existing ideas about the structural and functional organization of mitochondria. This makes it possible to study the previously inaccessible structural interactions of proteins with each other and with membranes in vivo.

Published: August 2024

Nowadays, people spend a lot of time in the information space, communicating within various social platforms. Content of those platforms can influence people’s feelings and personalities, which is especially relevant for young people. In this research, we made an attempt to prove this hypothesis. For the experiment, we selected the VKontakte social network and analysed users profiles together with the results of the psychological tests passed by them. The goal of the experiment was to find correlations between the information provided within the social network communities and the users’ personalities. Moreover, in this paper, we made an attempt to enhance the results of the classifier accuracy using the sentiment analysis. The experiments were conducted to test the sentiment analysis models, to analyse the proposed feature based on posts’ sentiment, and test the classifier for the detection of the potentially destructive impacts. The analysis of the correlation of the proposed feature with the communities that have potentially destructive impacts on anxiety is conducted. The analysis of the obtained results is provided. During the experiments, the authors found out that consideration of the posts’ sentiment allows increasing accuracy of the classifier for anxiety destructive impacts on 12.24 %. Additionally, we analysed the relationship between the user sentiments metric and destructiveness.

The utilization of Quantum Multi-Agent Systems (MAS) and Quantum Protocols in distributed agent environments has gained attention due to the need for enhanced protocol efficiency in quantum computing applications. Conventional methods often face limitations in achieving optimal performance, hindering the full potential of quantum computing in distributed settings. Existing approaches lack the necessary robustness to fully exploit the advantages offered by Quantum MAS, leading to inefficiencies in computational performance within distributed agent environments. In this context, we propose a novel Quantum MAS framework, which harnesses the principles of quantum superposition, entanglement, and advanced Quantum Protocols, including the quantum key distribution mechanism. The framework facilitates collaborative decision-making among agents through the utilization of joint quantum states and enables seamless synchronization of actions via the entanglement operator. The computational efficiency is optimized using quantum gate operations, thereby enhancing the overall computational performance in the distributed agent environment. We quantify the efficiency, showcasing the significant improvements achieved by the proposed Quantum MAS framework. Our research employs diverse datasets, including synthetic and real-world data, to comprehensively evaluate the performance and efficacy of the proposed Quantum MAS framework. Experimental results demonstrate a notable efficiency enhancement, with the proposed Quantum MAS achieving an average efficiency value of 0.92 across various experimental configurations and datasets. The findings underscore the significant potential of Quantum MAS in effectively addressing efficiency concerns within distributed agent environments, thus paving the way for broader applications of quantum computing in real-world scenarios.

Efforts are currently being made around the world to mitigate the impact of human activity on climate change. The construction sector is one of the largest sources of emissions. To reduce emissions, buildings must be energy efficient and use a significant amount of renewable energy. NZEB buildings are an important part of our transition to a lower carbon future. Efficient energy consumption in buildings is one of the most affordable ways to reduce the negative impacts of climate change and health-related problems. The purpose of the study is to analyze the regulatory requirements of European countries for NZEB buildings and compare them with the current norms in Ukraine. Determining the cost of energy-efficient structural solutions with current regulatory values. Based on the calculations and research, the following scientific and practical results were obtained. Analysis of norms in European countries for NZEB buildings and compare them with current norms in Ukraine. The calculated design values for NZEB buildings in Ukraine were considered. The needs for insulation of the wall, roof, and basement floor coverings were calculated according to the current norms in Ukraine and the norms proposed by the NZEB. The economic feasibility of measures to insulate the proposed normative options of NZEB was calculated. As a result of obtaining scientific and practical results of increasing the energy efficiency of enclosing structures, it shows that in terms of indicators of enclosing structures, Ukrainian standards are not lagging behind European countries, although they require further improvement and additional changes. The results of the economic calculation of the increase in the thickness of the insulation show that the NZEB standards have a more economic and thermal insulation potential in the long term compared to the current standards in Ukraine. The obtained research results can be used, as an example, in the design or reconstruction of buildings to increase the level of energy efficiency.

The results of calculating the coefficient of thermal conductivity of the developed construction of the pipeline from multilayer composite spatially oriented fiberglass are given. A method of calculating the coefficient of thermal conductivity of a pipe wall with a complex structure of reinforcement has been developed. The fiberglass pipe is made by the continuous method of oblique-layer longitudinal-transverse winding on a self-feeding frame of reinforcing pseudo-tape moistened with a binder in the form of a rarefied mesh. With each rotation of the mandrel, it shifts by the amount of hardening of the obtained two-component material under the influence of temperature. A comparison of calculated and experimental data was made. When comparing various known calculated dependencies and experimental values, the accepted physical model and the real structure of the material are determined. The known dependences obtained for a medium with infinite long parallel cylindrical inclusions for unidirectional and orthogonally reinforced materials and therefore for materials with a complex structure and scheme of reinforcements give errors and deviations. The work assumes that fiberglass consists of two components - a reinforcing filler and a binder with pores, the reinforcing fibers are endless and have a circular cross-section, the reinforcing fibers are evenly distributed in the matrix of the binder, there is an ideal thermal contact at the boundaries of the distribution between the reinforcement and the binder. Experimental data on determining the transverse thermal conductivity of unidirectional fiberglass rods with reinforcement based on aluminoborosilicate or magnesium-aluminosilicate glass and epoxy binders showed the smallest error in comparison with the calculated ones (8-10%). They investigated the fact that the coefficient of thermal conductivity of a fiberglass pipe is 100 times lower than that of a steel pipe. It was determined that it is possible to replace a steel pipe with a diameter of 219 mm with a fiberglass pipe with a diameter of 146 mm.
Understanding Bonded Labor: A Traditional System of Slavery in India

Published: August 2024

Bonded labor is a traditional system of slavery that continues to plague numerous countries, including India. It is often referred to as a traditional form of slavery as it has deep roots in the caste system that has historically denied equal rights and status to members who do not hail from the upper castes. The pain inflicted upon individuals and families through the bonded labor system is in fact much worse than the caste system itself. This system is a form of debt servitude in which individuals and their families are duped into a life of forced labor that is characterized by degrading treatment, physical violence, and mental suffering at the hands of the perpetrators. The objective of this article is to offer a thorough examination of the characteristics of this crime, its history, its frequency, the underlying factors contributing to its existence, the financial and psychological repercussions experienced by the victims, and the initiatives that have been implemented thus far in an effort to combat this issue. The present article on bonded labor highlights a major barrier to the 16th Sustainable Development Goal, which is about promoting just, peaceful, and inclusive societies. One of the key reasons why bonded labor continues to exist is the lack of sufficient international attention to it. The authors hope to help change that through the dissemination of key information about the bonded labor system that can be used to weaken and break this inhuman system and restore the health and wellbeing of the survivors.

In the era of revolution 5.0, advances in technology and information brought significant changes. From these changes, it is able to affect the system of everything related to humans such as in social, economic, political, educational and other life. The use of the play store as a medium and method of application in the learning process is a form of technology contribution to assist the education system. For example, the media for the dissemination of scientific studies, especially in the field of hadith, can be found in applications available on the play store. The study of hadith currently includes a lot of hadith historiography, the history of codification in the previous era and only a few studies that specifically discuss the development of hadith using the internet, especially in the realm of distributing hadith in the play store. In the past, the form of hadith can only be studied in the original print, it is different from now it can be seen in non-printed form such as applications. Of the many hadith applications available on the play store, the author takes three hadith applications, namely the hadith encyclopedic application of the book of 9 imams, children's hadith and hadith bushes. This study wants to show that hadith learning can be done other than through the original book and the three applications above are real evidence that hadith can be accessed easily through the play store with the help of the internet. This research is a type of qualitative research that has a descriptive nature and tends to use analysis. The results of this study indicate that the distribution of hadith in the play store has an influence on users in studying hadith. Then, the three hadith applications in the play store provide a new learning space for users to make it easier to solve the problems to be solved.

In ancient times, Japan sent a large number of scholars to China to learn cultural and economic knowledge. In the Tang Dynasty, it even reached its peak. At this stage, the number of Japanese entering China showed a trend of rapid growth. China's porcelain, agricultural products and tea also began to enter the Japanese market, which played a positive role in promoting the development of Japanese economy and the development of Japanese society. Subsequently, Japan entered the Meiji restoration stage, and they began to actively learn the cultural concepts of Europe. English and Spanish began to enter Japan, which had an impact on Japan's development, accelerated the progress of Japanese civilization to a certain extent and also had a certain impact on China. In this paper, the author will briefly study the characteristics and terms of Japanese language, hoping to provide corresponding reference for people to learn Japanese.
