A Review on Zoonotic and Economic Importance of Anthrax
Authors: A* Mohammed
Published: September 2024

Anthrax is a highly contagious disease caused by the bacterium bacillus anthracis, impacting both humans and animals, with a higher prevalence in livestock and economically significant wild animals. Herbivorous animals can contract the disease by inhaling or ingesting spores while grazing, while carnivores may become infected by consuming infected herbivores. In humans, infection typically occurs through contact with the spores via ingestion, inhalation, or direct contact. The disease does not spread directly from person to person; instead, the resilient spores of bacillus anthracis act as the primary source of infection, capable of surviving in the environment for extended periods. Severe outbreaks of anthrax have been observed in regions with tropical and sub-tropical climates and high rainfall. Essential measures for managing the disease include controlling infected animals, preventing contact with them and their products, implementing quarantine on affected properties, vaccinating potentially exposed livestock, disposing of dead animals properly, and disinfecting contaminated areas. Quarantine restrictions should be lifted only after no new cases of anthrax have been reported for at least six weeks following vaccination. Individuals exposed to the disease may receive an anthrax vaccine as a preventive measure. Bacillus anthracis is susceptible to various antibiotics such as penicillin, chloramphenicol, streptomycin, tetracycline, and erythromycin.

Diante do atual cenário global de esgotamento dos recursos naturais e ameaça à biodiversidade, a temática ambiental desponta como um dos temas mais relevantes para a humanidade. Nesse contexto, o Brasil possui como grande embate conciliar o desenvolvimento econômico à conservação de seus recursos naturais. Dito isso, a proteção do Bioma Caatinga, o único bioma, dentre os 6 existentes no país, exclusivamente brasileiro, constitui um importante desafio. Visto que, o setor econômico mais desenvolvido do país é o agropecuário, responsável por afetar diretamente os ecossistemas naturais. Desse modo, as Áreas de Reserva Legal (ARLs), atuam como instrumento legal de proteção da fauna e flora, garantindo os serviços ecossistêmicos do bioma Caatinga. O presente trabalho objetiva apresentar dados referentes à condição do Bioma Caatinga em ARLs do Rio Grande do Norte (RN), por meio de uma pesquisa quali-quantitativa, organizada em duas etapas de execução: levantamento bibliográfico e estudo de campo. Após análise e discussão, os resultados trouxeram de forma holística, dados referentes ao quantitativo de ARLs distribuídas por bioma, com ênfase no bioma Caatinga no Estado do RN, além de fazer a correlação dos dados numéricos apresentados, com as paisagens referentes ao bioma citado na região escolhida como objeto de estudo.

Propuesta didáctica-pedagógica para fomentar la autonomía del aprendizaje en los centros de autoacceso de idiomas en modalidad virtual
Authors: Morales Sánchez Oscar
Published: September 2024

El objetivo de esta investigación fue determinar el impacto que tiene la implementación de una propuesta didáctica en el aumento del grado de autonomía y el uso de estrategias que contribuyen al aprendizaje del idioma inglés en el Centro de Autoacceso (CAA) en modalidad virtual en la Universidad Autónoma de Querétaro, México. El diseño metodológico fue cuantitativo, descriptivo y correlacional. Para alcanzar el objetivo de la investigación, se diseñó y administró un cuestionario antes y después de la implementación de la propuesta. Este instrumento fue validado por juicio de expertos, y se recurrió a la relevancia entre ítem-constructo a través de la V de Aiken. 
Los resultados obtenidos muestran cambios significativos en la percepción de la autonomía, ya que la propuesta incorpora elementos que buscan desarrollar esta habilidad. Antes de su implementación, se abordaba el aprendizaje a nivel de contenidos lingüísticos.  Este cambio de percepción se atribuye al diseño de actividades para fomentar el aprendizaje autónomo dentro de la propuesta. Entre los cuatro grupos de estudio, se observó una diferencia en los niveles de autonomía entre el pretest y postest, siendo los estudiantes de semestres avanzados los que presentaron una mayor variación. Esto se atribuye a una mayor familiarización de los alumnos de grados superiores con el uso de actividades de autoaprendizaje en el CAA. Se concluye que la autonomía en el CAA se incrementa cuando una propuesta didáctica-pedagógica contiene estrategias y actividades que contribuyen a su desarrollo.
Do Comorbidities and Body Mass Index Influence Shoulder Pain, Disability and Joint Range of Motion?
Authors: Tombak Yasemin
Published: September 2024

Aim: Shoulder diseases are believed to be associated with metabolic factors including diabetes and obesity. Our research aimed to determine how age-related comorbidities and rising body mass index (BMI) affected shoulder pain, disability, and joint range of motion (ROM).

Methods: The study included 137 individuals aged 20–80 who sought treatment for chronic shoulder pain at the physical medicine and rehabilitation outpatient clinic and, they were recorded for their demographics, BMI, comorbidities, pain duration, dominant shoulder, affected shoulder, history of treatment, joint ROM, visual analogue scale pain score, and shoulder pain and disability index score.

Results: The study found that the obese group had a high mean age (p=0.047) and substantially more common thyroid dysfunction (p=0.031). When individuals with and without diabetes mellitus (DM) were compared, it was observed that the DM group had significantly less ROM. Similarly, ROM was found to be considerably lower in the group with hypertension (HT) when a comparison was made for having or not having HT. In comparison of patients with or without hyperlipidemia (HL), the group with HL had significantly lower BMI compared to the group without HL (p=0.047). Upon comparing the groups with and without thyroid disease, it was discovered that the former had a considerably higher BMI (p=0.012).

Conclusion: We found that the two most prevalent disorders associated with shoulder pain, DM and HT, have a particularly positive influence on joint range of motion. We also observed a connection between thyroid problems and BMI. In the management of shoulder discomfort, managing comorbidities and BMI are crucial.

Published: September 2024

Increasing the resource base and extraction of hydrocarbons remains one of the main tasks of engineers and scientists, and this is especially relevant in the war conditions in Ukraine. Ultra-deep drilling (>6 km) and the extraction of hydrocarbons from low-permeability unconventional reservoirs are possible directions for the implementation of these tasks, especially taking into account the high depletion of active deposits (of about 75 %) and the good cover of the Dnipro-Donets Basin by exploratory drilling. The results of laboratory studies and the interpretation of well logging data of unconventional reservoirs of Visean sediments (V-23 and V-24-25) indicated that these intervals are promising. An important feature is that these layers are located within the northwestern and southeastern parts of the Dnipro-Donets Basin, with a total area of promising areas of about 8,000 km2. However, ultra-deep drilling and extraction of hydrocarbons from unconventional reservoirs requires modern technological approaches and solutions. In order to choose the optimal location (a «sweet spot»), to investigate the optimal program of drilling, geological study, and completion of the studied wells, it is necessary to construct the most accurate geological model of this reservoir. This paper constructed a petrophysical model of unconventional-type reservoirs with high total organic content (TOC) based on well logging data of old fund wells with a typical complex of well logging. The model was calibrated on the data of modern geophysical complexes (SGR, neutron-gamma spectroscopy, NMR, lithodensity, etc.) and special core studies (XRD, LECO, TOC, etc.). The equation for calculating the target formations’ total porosity, TOC, and mineralogical composition was derived using the method of multilinear regressions in the «Techlog» wellbore interpretation software complex. The results showed good correlations for unconventional reservoirs of Dnipro-Donets Basin North-Western Play (Glynsko-Solokhivskiy oil and gas region) and Dnipro-Donets Basin Southeastern Flank Play. The magnetic susceptibility of the target reservoirs was researched, and its correlation dependences with other physical parameters of the rocks were also investigated. In particular, a direct correlation of magnetic susceptibility and porosity was determined. This article is a continuation of a series of publications on the study of Visean unconventional reservoirs within the DDB.

Published: September 2024

The paper aimed to determine the relationship between water discharge and the concentration of nitrate nitrogen compounds in a river during spring and rainfall floods. The study was carried out in a small experimental catchment of the Boguslavka River in the forest-steppe zone of Ukraine, most of which is used for agricultural production.
Analysing the hysteresis of nitrate compounds (hysteresis is the phenomenon of lagging system response to the action of a factor associated with the «memory» of its previous action) allowed us to obtain new information about the patterns of nitrate nitrogen compounds inflow during runoff-forming phenomena.
During the spring flood, the highest concentrations of nitrate compounds in water were observed before the snowmelt began. A sharp increase in water discharge led to a decrease in the N–NO3-content,which began to increase on the downward limb of the runoff hydrograph. During the spring floods of 2017-2018, a counterclockwise hysteresis was formed, indicating that the main supply of nitrate compounds came from remote sources. In 2017, the frozen topsoil did not contribute to the flow, whereas in 2018, prolonged flooding led to the washing of the coastal zone soils.
During the summer floods, N–NO3- concentrations in the river water during the decline phase of the hydrograph were caused by significant nitrogen emissions and exceeded the concentrations before the event. The hysteresis loop was directed clockwise, indicating a higher concentration of nitrate compounds in the coastal zone. During the rain with wet preliminary conditions, the hysteresis shape was complex and resembled an 8-like shape. In this case, the increase in concentrations in the stream began at the limb of the hydrograph rise.
When snowmelt was combined with rainfall or prolonged rains in the summer, a two-peak hydrograph was formed, and the hysteresis index of the second one was much lower than the first. The area of the hysteresis loop was significantly affected by the conditions of preliminary moistening.

The aim of this research is to analyze changes in social construction and the division of domestic labor in modern households in an urban environment. Social construction, which involves norms, values and social expectations, plays an important role in the division of domestic labor in the family. Factors such as cultural traditions, religion, internalized gender roles and influences from the social environment contribute to the formation of social construction. The research method used is qualitative literature study, researchers analyze and collect scientific articles, journals, books and other sources relevant to this research topic. The theory used is social construction theory developed by Peter L. Berger and Thomas Luckmann. This theory is used to identify how norms, values and social roles in domestic work are constructed, internalized and changed in the context of the modern family. The results of this research show that stereotypical gender roles and behavioral expectations for women in domestic work burden women in the unequal division of work between husband and wife. Apart from that, this research also shows that there are various significant changes in the social construction related to domestic work in modern families, such as shifts in gender roles and awareness of gender equality. One of the factors that can influence a husband and wife or a modern family to adopt an egalitarian division of labor is education, work experience and individual values.

The key goal of the study is to identify aspects of the implementation of blockchain technologies in human resource management and argue for the moderating role of institutional support. The need to introduce new technologies at both the tactical and strategic levels is substantiated. It is highlighted that the key core of modern organizations is the human resource management system. The role of integration of blockchain technologies in human resource management, which ensures the effective training of qualified personnel at the right time and in the right place, is argued. It has been determined that the introduction of blockchain technologies in human resource management facilitates the organization of cooperation between countries in updating skills and knowledge based on compliance with competency standards and corporate governance rules. A survey of 300 employees of the pharmaceutical industry in Jordan was conducted, which served as the basis for a multivariate analysis to confirm reasonable hypotheses. The results obtained are valuable and can be applied in practice in terms of determining the impact of the implementation of blockchain technology in the human resource management system and on the UTAUT structure, which in turn provides institutional support.
Incorporating economic indicators and market sentiment effect into US Treasury bond yield prediction with machine learning
Authors: Li Zichao , Wang Bingyang , Chen Ying
Published: September 2024

Accurate prediction of US Treasury bond yields is crucial for investment strategies and economic policymaking. This paper explores the application of advanced machine learning techniques, specifically Recurrent Neural Networks (RNN) and Long Short-Term Memory (LSTM) models, in forecasting these yields. By integrating key economic indicators and policy changes, our approach seeks to enhance the precision of yield predictions. Our study demonstrates the superiority of LSTM models over traditional RNNs in capturing the temporal dependencies and complexities inherent in financial data. The inclusion of macroeconomic and policy variables significantly improves the models’ predictive accuracy. This research underscores a pioneering movement for the legacy banking industry to adopt artificial intelligence (AI) in financial market prediction. In addition to considering the conventional economic indicator that drives the fluctuation of the bond market, this paper also optimizes the LSTM to handle situations when rate hike expectations have already been priced-in by market sentiment.
The mechanism and boundary conditions of farmers’ income increase in financial services: A case study of Yunnan Province
Authors: Khan Muhammad Shahid
Published: September 2024

Finance is the core of the modern economy and the bloodline of the real economy; adherence to the people-centered value orientation and the financial services of the real economy as the fundamental purpose is an important connotation of the road of economic development with Chinese characteristics. Financial work is distinctly political and people-oriented, and must consciously practice the concept of the people, serve agricultural and rural development and farmers to increase their income and contribute to the common prosperity of farmers and rural areas. This study is based on the key factors affecting the multidimensional poverty of rural households—external rural financial resources availability and internal rural household entrepreneurship, rural household risk resilience, and rural household financial capability joint analysis. Based on financial exclusion theory, financial inclusion theory, poverty trap theory, and financial literacy theory, to build a logical framework between the rural financial resources availability, farmers’ financial capability, farmers’ entrepreneurship, farmers’ risk management capability, and farmers’ poverty, and then empirically explore the optimization mechanism of poverty reduction for farmers, and analyze the heterogeneity of the financial resources availability, to reduce the return to poverty caused by the lack of entrepreneurial motivation and the low level of risk resilience of rural households. The study aims to improve the farmers’ financial capability and promote sustainable and high-quality development of rural households. In this study, we modeled financial resource availability and rural household poverty using structural equations and surveyed rural households using a scale questionnaire. It was found that financial resource availability significantly affects rural household risk resilience, farmers’ entrepreneurship, and rural household poverty and that rural household risk resilience significance mediates the relationship between financial resource availability and rural household poverty, financial capability plays a significant moderating role. However, the mediating effect of farmers’ entrepreneurship on the availability of financial resources and farmers’ poverty is insignificant. Here, we put forward corresponding countermeasures and recommendations: guiding the allocation of financial resources to key areas and weak links; optimizing financial services; and building a long-term mechanism.

Published: September 2024

Improvement of life quality, food production and sustainability requires search for better, efficient natural resources extracting methods, while minimizing environmental impact, which is determined by carbon and water footprint calculation. In order to counter global phenomena, it is necessary for food-producing chain to work together to take conscious action on environment. Restoring balance demands action to reduce greenhouse gas emissions and rational water use, by reducing energy intensive processes or increasing efficiency of wastewater treatment methods. This requires a thorough understanding of all phenomena that determine a given process. Viscous fingering occurs during such processes as enhanced oil recovery, metal crystallization in batteries, sugar refining, groundwater purification and many others. Research to improve knowledge of this phenomenon and ability to predict its effects is crucial in development of basic industrial processes. This paper presents an experimental study of tracking immiscible viscous fingering in modified Hele-Shaw cells filled with a granular bed of known parameters. The influence of bed parameters and flow conditions on the observed phenomenon was investigated. During the tests, beds with the following grain diameter ranges were used: 200–300, 300–400 and 400–600 μm; the liquid was injected at three different flow rates in the range of 100–400 ml/h. On the basis of carried out work, a model of the studied phenomenon was proposed, which made it possible to determine the extent and the fingering scale.

Published: September 2024

These studies were carried out within the framework of the European FuelSOME Project (No. 101069828), which focuses on establishing a multi-fuel energy generation system based on utilization of Solid Oxide Fuel Cells (SOFC) and is dedicated mainly to the long-distance maritime shipping. For the SOFC stacks, the removal of sulphur contaminations from fuels is crucial as the content of sulphur compounds is strictly limited, even to dozens of mol ppb. The modelling and calculations were performed for a selected testing system of deep adsorptive purification of methanol to remove dibenzothiophene (DBT) on activated carbon (AC), where DBT was taken as a representative of compounds contaminating sulphur. An appropriate model of the adsorption column packed with activated carbon pellets was elaborated as a basis for process simulations and further techno-economic considerations. The research focused on modelling sulphur removal to achieve the required purity of methanol, then on cost analysis to optimize the proposed purification process. At the current stage, the aim of the performed studies was a preliminary check of a possibility of successfully performing deep adsorptive desulphurisation of methanol and an estimation of purification costs.
Study on microbioplastic leachates: Released compounds and impact on higher plant growth
Authors: Liwarska-Bizukojć Ewa , Bizukojć Marcin
Published: September 2024

The effects of leachates from newly-synthesized bioplastics on the early stages of higher plant growth were studied together with the putative identification of the chemicals in the given microbioplastic leachates. Three polylactide-based bioplastics and pure polylactide (PLA) were subjected to the phytotoxicity tests (1) to determine the intrinsic effects of chemicals on the germination and early growth of plants without prior incorporation of the chemicals into a soil and (2) to find the impact of the chemicals introduced into a soil on the germination and plant growth. Plants Sorghum saccharatum, Lepidium sativum and Sinapis alba were used. For two out of four microbioplastics the total ion chromatograms revealed the presence of chemicals in the leachates. Out of 20 individual m/z values, 6 were putatively attributed to the known compounds. Microbioplastic leachates did not affect seed germination and contributed rather to the stimulation than inhibition of the early plant growth. In the soil tests the inhibition of root and shoot growth of dicotyledons occurred more frequently than in the liquid phase tests. It indicates the potential interactions between the chemicals in the leachates and soil matrix. Dicotyledons were more sensitive than monocotyledons in the evaluation of phytotoxicity of microbioplastic leachates.

Published: September 2024

Purpose

To address the “anomalies” that occur when scientific breakthroughs emerge, this study focuses on identifying early signs and nascent stages of breakthrough innovations from the perspective of outliers, aiming to achieve early identification of scientific breakthroughs in papers.

Design/methodology/approach

This study utilizes semantic technology to extract research entities from the titles and abstracts of papers to represent each paper’s research content. Outlier detection methods are then employed to measure and analyze the anomalies in breakthrough papers during their early stages. The development and evolution process are traced using literature time tags. Finally, a case study is conducted using the key publications of the 2021 Nobel Prize laureates in Physiology or Medicine.

Findings

Through manual analysis of all identified outlier papers, the effectiveness of the proposed method for early identifying potential scientific breakthroughs is verified.

Research limitations

Objetivo: O objetivo deste estudo é avaliar a perda de solo por erosão em áreas da Bacia Hidrográfica do Rio Capim (BHRC), localizada no Nordeste Paraense, utilizando a Equação Universal de Perda de Solo Revisada (EUPSR) e ferramentas de sensoriamento remoto e geoprocessamento, gerando um mapa de perda de solo por erosão hídrica.
Método: utilizou-se a versão Revisada da Equação Universal de Perda de Solo (EUPS). A Variável R (Erosividade) foi calculada através das medições históricas de 2001 a 2021 nas estações meteorológicas ao longo da Bacia Estudada, enquanto as variáveis LS foram obtidas com a utilização de imagens de satélite para determinação de Modelo Digital de Elevação (MDE). O fator K (Erodibilidade do solo) foi determinado a partir de uma revisão bibliográfica e o fator CP foi calculado através da elaboração do mapa de uso e ocupação do solo.
Resultados e Discussão: Os resultados classificam a erosão da área estudada com grau suave a moderado cujo valor médio de perda de solo correspondeu a 3,2318 t/ha.ano. Os fatores com maior contribuição para este resultado foram a erodibilidade e a declividade do terreno.
Implicações da Pesquisa: Estes resultados podem nortear o planejamento do uso e ocupação dos solos da área, bem como a adoção de técnicas adequadas de manejo visando a sustentabilidade do uso das terras.

Federal state educational standards set teachers the task of preparing students for project, educational and research activities. Teachers gain experience in design and scientific research in the process of obtaining professional education, participating in scientific and methodological conferences, preparing coursework, diploma work, and master's research. At the moment, it has not been sufficiently studied to what extent the experience gained by future teachers influences their activity in this area at the stage of professional activity, which is the problem considered in this article. The study uses theoretical (analysis, synthesis) and empirical methods (questionnaires, correlation analysis, N. Kruskal-Wallis statistical test). The results of the study show that the presence and characteristics of the connection between the research experience gained by future teachers at a university and their research activity in the profession is determined by the professional experience of teachers. Teachers whose experience is more than 20 years, who were actively involved in science at a university, are more inclined to believe that research activities are part of their professional activities and they are more diverse; they take part in organizing the project and research activities of students. Teachers with less than 5 years of experience who were active in research activities during their studies at a university are statistically significantly more likely to note that they continue to engage in this activity in an educational organization. The responses of teachers with 5–10 years of experience and 10–20 years of experience did not show a statistically significant correlation. Analysis of the survey data suggests that maintaining and increasing the activity of teachers in the field of research activities requires organizational and managerial decisions on the part of the leadership of the educational institution, and also suggests that advanced training and retraining of the teaching staff should be carried out in programs where writing a final qualifying work is a prerequisite for obtaining a certificate. These assumptions require separate research.

The relevance of research into personal factors of socio-psychological adaptation of military personnel is due to increased requirements for ensuring the defense capability and security of the country. The purpose of this study was to empirically substantiate the relationship between aggressiveness as a personal characteristic of military personnel undergoing military service and their socio-psychological adaptation. In a study using Diamond-Rogers socio-psychological adaptation questionnaires adapted by A.K. Osnitsky and the personal aggressiveness of Bass-Darka in the adaptation of S.N. Enikolopov and N.P. Tsibulsky interviewed 50 conscripts aged 18 to 24 years. The results of the correlation analysis showed that there is a connection between indicators of adaptation and aggressiveness as a personal characteristic among conscripts. At the same time, socio-psychological adaptation was most associated with indicators of physical and verbal aggressiveness. The indicator of maladaptation turned out to be consistently associated with the index of hostility, suspicion and guilt. The results obtained were interpreted in the context of data obtained by other researchers that aggressiveness in certain conditions performs a positive function and manifests itself in perseverance and fearlessness in the face of difficulties.
Synergistic enhancement of photoelectrocatalytic activity and photostability in CdS photoanodes by ultrathin polydopamine layer

CdS-based photocatalyst and photoanode have recently drawn the attention of several investigators primarily in connection with its excellent visible light response in various catalytic reactions involving light, especially photoelectrochemical (PEC) water splitting. The present approach highlights the concept of constructing a biological functional layer incorporated for photochemical instable semiconductors for practical PEC applications. However, practical applications of CdS-based photoanodes are limited by rapid charge recombination and severe photo corrosion. This study introduces a novel approach to enhance reaction kinetics and stability. We present a CdS nanorod photoanode with an ultrathin layer of polydopamine (PDA), prepared through a conformal polymerization assembly process, which serves as a robust platform for subsequent assembly of hole cocatalysts FeOOH. The resulting sandwich structure of CdS/PDA/FeOOH photoanode demonstrates an incident to current efficiency (IPCE) of 7.1% at 420 nm and a photocurrent of 1.9 mA/cm2 at 1.23 V versus the reversible hydrogen potential (RHE). The integrated photoanode exhibits significantly prolonged photostability compared to CdS, CdS/PDA, and CdS/FeOOH photoanodes. The significance of this work lies in constructing a FeOOH structure (with hole extraction and consumption capabilities) on the CdS outermost layer using an easy-to-operate preparation process, thereby revealing the ability of PDA to enable the passage of photogenerated holes. The present approach highlights the concept of integrating biologically functional layers to stabilize photochemically unstable semiconductors for practical PEC applications.

The current control methods for virtual synchronous generators (VSG) in regulating inverter frequency in standalone microgrids at border posts and remote mountainous regions remain suboptimal. This study introduces a small-signal VSG model to elucidate the intrinsic dynamics of the virtual inertia and damping coefficient, along with their coupled interrelationship. A novel VSG control approach is proposed, featuring synergistic adaptive regulation of both virtual inertia and damping coefficient. This approach is designed to optimize the interaction of the virtual inertia and damping coefficient with the frequency difference and rate of frequency variation, within a predefined operational range. Additionally, it adaptively modulates these parameters to mitigate further frequency reductions, taking into account the frequency difference and active power when deviations occur outside the predefined range. The experiments demonstrate that this approach effectively moderates the rate of frequency change, diminishes frequency departure velocity for approximately 4 times the original during disturbances, expedites frequency stabilization post-disturbance, the stabilization time is reduced by at least half of the original and prevents excessive frequency deviations. The implementation of this method significantly enhances the response speed and accuracy of frequency control in standalone microgrids, contributing to improved overall system stability.
