Global disparities in transboundary river research have implications for sustainable management
Authors: Sahana Mehebub , Dhali Md Kutubuddin , Lindley Sarah
Published: December 2024

Anthropogenic pressures, climate change, and hydro-politics pose significant risks for sustainable transboundary river basin management. We reviewed 4237 publications using machine learning and conducted a desk review of 325 publications, analyzing 4713 case studies across 286 basins. Our objectives were to: assess major perspectives and key research themes; analyse how they vary based on basin size, location, runoff, water withdrawal, discharge, and consumption; and reflect on implications for sustainable basin management. Findings show that the volume of research in the global south is disproportionately small compared to basin population size, water withdrawals and water consumption. Moreover, research is predominantly led by global north institutions, shaping study themes and locations. While research in the global south focuses on hydro-politics and natural hazards, the global north emphasizes landscape ecology and governance. These insights highlight the need for more comprehensive assessments in the global south to support sustainable management of transboundary river basins.

Published: December 2024

Chronic inflammatory diseases, e.g., obesity, cardiovascular disease and type-2 diabetes, progressively suppress the anti-inflammatory heat shock response (HSR) by impairing the synthesis of key components, perpetuating inflammation. Monitoring HSR progression offers predictive value for countering chronic inflammation. This study quantified HSR in high-fat diet (HFD) and normal chow (NC) mice by measuring 70 kDa heat shock protein (HSP70) expression after heat treatment of whole blood samples. To align with human translational relevance, animals were housed within their thermoneutral zone (TNZ). Whole blood was heat-challenged weekly at 42 °C for 1–2 hours over 22 weeks, and ΔHSP70 was calculated as the difference between HSP70 expressions at 42 °C and 37 °C. Results correlated with fasting glycaemia, oral glucose tolerance test, intraperitoneal insulin tolerance test and 2-hour post-glucose load glycaemia. ΔHSP70 levels >0.2250 indicated normal fasting glycaemia, while levels <0.2125 signalled insulin resistance and type-2 diabetes onset. A logistic model (five-parameter logistic) showed progressive HSR decline, with HFD mice exhibiting earlier ΔHSP70 reduction (t1/2 = 3.14 weeks) compared with NC mice (t1/2 = 8.24 weeks), highlighting compromised anti-inflammatory capacity in both groups of mice maintained at TNZ. Remarkably, even NC mice surpassed insulin resistance thresholds by week 22, relevant as control diets confronted interventions. Observed HSR decline mirrors tissue-level suppression in obese and type-2 diabetic individuals, underscoring HSR failure as a hallmark of obesity-driven inflammation. This study introduces a practical whole-blood assay to evaluate HSR suppression, allowing assessment of glycaemic status during obesity onset before any clinical manifestation.
DC allowable electric field strength for naphthenic‐based and paraffin‐based transformer oils
Authors: Gao Chunjia , Qi Bo , Chen Binhao , Wu Juzhen , Li Chengrong
Published: December 2024

Currently, the design of transformers insulation predominantly depends on the allowable alternating current (AC) field values for insulating oil established by Weidmann in the 1980s, lacking the research under direct current (DC) voltage for converter transformers. This study selects naphthenic oils and paraffin‐based oil transformer oil as research subjects, establishing a practical measurement platform to ascertain the oil breakdown characteristics under DC voltage. Furthermore, it statistically analyses the allowable DC field values of the oil. The findings elucidate that (1) the three‐parameter Weibull distribution is more suitable to conduct a statistical analysis for oil breakdown probability, yielding a fitting degree up to 99.95%. (2) for a constant electrode spacing, a 14.81% voltage increment escalates the breakdown probability of the oil gap from 3.33% to 73.33%. Concurrently, an increase in electrode spacing leads to a substantial decrement in the breakdown field strength of transformer oil, with KI25X experiencing a 54.51% reduction as electrode spacing extends from 5 to 25 mm. (3) the constant terms of the allowable DC field strength for S4, KI50X, and KI25X are found to be 19.728, 17.221, and 19.281, respectively. (4) a thorough analysis for differences in physicochemical properties and electrical parameters elucidates the variations in insulation properties across different transformer oils. The findings presented in this study offer essential theoretical and technical foundations for the design, evaluation, and enhancement of insulation structures in converter transformers.
Estimating uncertainties in the back-mapping of the fast solar wind
Authors: Koukras A. , Dolla L. , Keppens R.
Published: December 2024

Context. Although the most likely source regions of fast solar wind relate to coronal holes, the exact acceleration mechanism that drives the fast solar wind is still not fully understood. An important approach that can improve our understanding involves the combination of remote sensing and in situ measurements, often referred to as linkage analysis. This linkage tries to identify the source location of the in situ solar wind with a process called back-mapping. Typically, back-mapping is a combination of ballistic mapping, where the solar wind draws the magnetic field into the Parker Spiral at larger radial distances, and magnetic mapping, where the solar wind follows the magnetic field line topology from the solar surface to a point in the corona where the solar wind starts to expand radially.

Aims. By examining the different model ingredients that can affect the derived back-mapped position, we aim to provide a more precise estimate of the source location and a measure of confidence in the mapping procedure. This can be used to improve the connection between remote sensing and in situ measurements.

Methods. For the ballistic mapping, we created velocity profiles based on Parker wind approximations. These profiles are constrained by observations of the fast solar wind close to the Sun and are used to examine the mapping uncertainty. The coronal magnetic field topology from the solar surface up to an outer surface (the source surface) radius RSS is modeled with a potential field source surface extrapolation (PFSS). As inputs, the PFSS takes a photospheric synoptic magnetogram and a value for the source surface radius, where this latter is defined as the boundary after which the magnetic field becomes radial. The sensitivity of the extrapolated field is examined by adding reasonable noise to the input magnetogram and performing a Monte Carlo simulation, where we calculate the source position of the solar wind for multiple noise realizations. Next, we examine the effect of free parameters –such as the height of the source surface– and derive statistical estimates. We used Gaussian Mixture clustering to group the back-mapped points associated with different sources of uncertainty, and provide a confidence area for the source location of the solar wind. Furthermore, we computed a number of metrics to evaluate the back-mapping results and assessed their statistical significance by examining three high-speed stream events. Finally, we explored the effect of corotation close to the Sun on the derived source region of the solar wind.

Results. For back-mapping with a PFSS corona and ballistic solar wind, our results show that the height of the source surface produces the largest uncertainty in the source region of the fast solar wind, followed by the noise in the input magnetogram, and the choice of the velocity profile. Additionally, we display the ability to derive a confidence area on the solar surface that represents the potential source region of the in situ-measured fast solar wind.

Development of a standard mileage for large-sized tires under moderately severe quarry conditions
Authors: Yusupov Umidbek , Shavkatov Xumoyun
Published: December 2024

The tire life depends on many factors, such as the correct loading of the dump truck, longitudinal and transverse slopes of the road, turning radius, internal tire pressure, uniform distribution of the loaded ore, average operating speed of the dump truck, road surface, its condition and type, driver skill, ambient temperature, etc. It has been studied that one of the ways to increase the mileage of tires can be to reduce the number of sections, if technically possible, with longitudinal slopes of more than 8%. Based on the results of the experiment conducted at Navoi Mining and Metallurgical Combine, standard mileage of large-size Michelin tires for average operating conditions has been developed, i.e. with an average longitudinal (4%) road slope along the entire length of the transportation route and a strength factor of the mined rock of 7, according to the M.Protodyakonov scale, from which the quarry road is laid. This makes it possible to estimate the tire service life in any quarry conditions according to the developed standard mileage. Based on the test results, recommendations were developed for the rotation of large-size dump truck tires separately for the summer period and separately for other seasons, as well as recommendations for the correct use of tires.

Environmental behavior and mindset: Utilitarianism vs. duty ethics
Authors: Bikmetov Evgeniy , Lukyanov Arkadiy , Pushkareva Marina , Garipova Galiya , Itkulova Leisian
Published: December 2024

The purpose of the research is to develop philosophical and ethical foundations of ecological behavior, as well as thinking that generates creative consciousness, dialog communication, directed against the utilitarian approach to reality. The novelty consists, firstly, in substantiating the idea of developing the essential forces of man, which are not opposed to the everyday world, but harmonize it with spiritual satisfaction. Ecological thinking and behavior do not arise randomly and automatically, but require moral effort. Normative action is connected with human efforts to join the world of humanism and love as an invariant that remains unchanged in various cultural and historical forms. Secondly, the modern understanding of the ethics of human duty involves requirements for human action to be neither destructive of future existence nor threatening to the preservation of life. The conclusions are based on the deontological understanding of ethics of duty. The applied dialectical method, which is based on the principle of activity of self-consciousness, is associated with the rise above utilitarianism, overcoming the consumerist, technocratic attitude to the surrounding world, operating with quantitative indicators of intellectual progress. The research is based on the principle of additionality of sensuality and reason, pleasure and duty. The authors substantiate the transcendental way of cognizing the ecology of man and society. Human needs and interests lie at the foundation of understanding the social and spiritual consequences of a committed action. Harmony of the principles of duty and love is promoted by creative overcoming of utilitarianism and recognition of the limits of possibilities of impact on the natural environment. Environmental behavior must be viewed in the context of the rich world of human individuality, which contributes to the harmonization of ethical duty and pleasure.

Machine learning in environmental sustainability factor analysis in the agricultural sector
Authors: Kukartsev Vladislav , Kozlova Anastasia , Kukarceva Svetlana
Published: December 2024

The study employed several key data analysis methods aimed at enhancing the understanding of relationships between variables and improving prediction accuracy. The primary tool used was correlation analysis, which allowed for the identification of the degree of association between two variables by determining how changes in one variable relate to changes in another. This established a foundation for further in-depth data analysis. For a deeper understanding and simplified interpretation of the data, factor analysis was utilized. This method helped to identify latent factors that explain the relationships between observed variables and to reduce the number of variables by grouping them. This made the analysis easier and facilitated the identification of key components affecting the data. Logistic regression was applied to build data models. This method is used to model the probability of a specific event occurring based on independent variables, allowing for the classification and prediction of categorical outcomes. The logistic function was used to estimate probabilities and the relationship between the dependent variable and predictors. To enhance the performance of the logistic regression model, a Weight of Evidence (WoE) analysis was conducted. This method converts categorical and continuous variables into numerical formats, simplifying data interpretation and improving the model’s predictive capabilities. WoE analysis helps to identify significant factors, improve the linear relationship between predictors and the dependent variable, and reduce the impact of outliers, which is particularly important in areas such as credit scoring. The results of applying these methods showed that the model based on correlation and factor analysis explained 27.51% of the information on the training set and 76.04% on the test set.

Authors: Gorbatov Sviatoslav
Published: December 2024

Currently, the tourism industry is actively involved in solving the problems of climate change and environmental protection. The dependence of many tourist destinations on natural attractions makes the tourism industry responsible for the ecological deterioration of the host territories. In the modern world, favorable conditions have been created for the travel of young people, and therefore youth tourism is a self-sufficient tourism sector. The study proposes to consider the development of youth tourism in terms of sustainability, and hence an analysis of the attitude of the younger generation to the environment during tourist trips was undertaken. A comparative assessment of the negative impact of tourists of different age groups, in particular, young people, on the environment was carried out. Using a sociological survey, the position of young tourists on the issues of careful attitude to natural attractions, and the priority of environmentally friendly tours based on the principles of sustainability was revealed. The young people's degree of understanding of the signs and criteria of an ecologically friendly tour was established. The difference in the price that young tourists are willing to pay for a tour that meets all the sustainability criteria was revealed. As a result, by analyzing the responses to the questionnaire, those respondents who have high environmental awareness were highlighted.

According to the principle of different methods, the existing forecasting methods are roughly divided into three parts: traditional forecasting methods, intelligent forecasting methods, and hybrid forecasting methods. Through the introduction and analysis of each method, this paper finds that the traditional prediction method is only effective in simple linear or nonlinear models. The intelligent prediction method has wider applicability and accuracy, and is also the mainstream prediction method. The hybrid prediction method is a relatively new prediction method, which has better prediction effect. The induction and summary of the prediction methods in this paper provide reference for the follow-up research on agricultural product price prediction.

Authors: He Xiaoyan
Published: December 2024

Agriculture is a complex process that requires a great deal of knowledge and experience. Yet, the complexity and often chaotic nature of web data presents a considerable challenge in obtaining suitable results. Given these production requirements, there is an urgent need to develop a model that enables machine reading comprehension and caters to automatic question-answering scenarios within the scope of agricultural production. In this paper, we construct a dataset for the experiments of document QA in agricultural scenarios. We import two model (ask-my-pdf and chat-pdf) as our baseline and use them to do the single and multiple document QA task. Then, we proposed several methods to improve the performance of the model in agriculture scenarios. At the end of the experiment, we achieved 33.3% improvement in F1 score compared to baseline and 92.8% overall answer accuracy in single document QA. For our final multiple documents QA model, we achieved 53% improvement in F1 score compared to baseline and 83.3% overall answer accuracy in the task.

Published: December 2024

Today, China’s productivity is steadily growing, and the output of agricultural and sideline products is also increasing. There is an increasing need for the preservation of fresh foods such as vegetables that are not consumed immediately after harvest or sale. Electric field technology, as a new method of preservation, features the advantages of extending the shelf life, being sustainable, pollution-free, and consuming less energy. Compared to traditional preservation methods, it better meets modern demands for healthy, green food. This article evaluates the effects of high-voltage pulsed electric field treatment on the preservation of fresh milk and carrot juice through experimental verification. The study found that within the range of output voltages from 20kV to 30kV, output frequencies from 100Hz to 200Hz, and treatment times from 1 minute to 2 minutes, the factor that most significantly affects the high-voltage pulse electric field sterilization and preservation effect is the output frequency, while the impact of the output voltage is not significant. Based on the results, the paper discusses the potential applications and future prospects of electric field technology in the field of food preservation, providing suggestions and directions for future research and application.
Research on Risk Control in Coffee Milk Beverage Production Based on HACCP and FMEA
Authors: Wang Zihang
Published: December 2024

This study aims to identify hazards and potential risks at each stage of coffee milk beverage production through a combined approach of HACCP (Hazard Analysis and Critical Control Points) and FMEA (Failure Mode and Effects Analysis). It proposes risk control measures and determines the production process's CCPs (Critical Control Points). The analysis of the production process categorizes it into five parts: “Raw Materials and Auxiliary Materials Inspection”, “Preprocessing of Coffee Milk Beverages”, “Post-Processing of Coffee Milk Beverages”, “Physical Hazard Detection”, and “Allergen Hazard Prevention.” Through the CCP decision tree and RPN value calculation, hazards, including physical, chemical, biological, and allergenic hazards, were accurately identified. The results show seven CCPs in coffee milk beverage production. First, chemical hazards from pesticide residues, heavy metal contamination, and excessive food additives during raw material acceptance and mixing. Second, biological hazards from mycotoxins and pathogenic bacteria during roasting and sterilization. Third, physical hazards from metal and plastic residues and allergenic hazards from allergens during processing and packaging. Finally, the study presents specific prevention and corrective plans using HACCP teams and planning charts, effectively reducing production risks and ensuring product quality and consumer safety.

Published: December 2024

As a higher social insect, ants have a clear hierarchy within them. According to the different divisions of labor, ant groups mainly include worker ants, soldier ants, male ants, and queen ants. In this paper, the social division of labor and its influencing factors on ants are studied in-depth. The main characteristics, physiological functions and behaviors of different grades of ants are explained, and the strong correlation between them and the social division of labor of ants is discussed from the aspects of gene differential expression, epigenetic regulation and brain specificity. From the behavioral level to the molecular level, this paper reveals the social division of labor and influencing factors of ants and lays an essential foundation for the study of ants' social behavior.

Chlorella has been widely used in bioenergy, environmental protection, carbon reduction, food, pharmaceutical and other fields. In this paper, a comprehensive analysis is made on the optimization of light conditions in chlorella in recent years by way of literature review. The results showed that the biomass accumulation rate of chlorella was faster in the light intensity range of 5500-7000lux, but the growth rate of chlorella reached a limit in the extremely high light intensity range of 10000-14000lux；blue and green light had the greatest effect on the biomass and photosynthetic pigment accumulation of chlorella; blue and green light monochromic light culture mode had the highest lipid yield; adding green light to blue-white light, red-white light and white-green light was beneficial to the lipid accumulation of chlorella; In the 24h culture mode, the low frequency light period of 14L:10D is the best scheme in general. According to the above conclusions, the light conditions, the effects of composite light on Chlorella and the optimal low-frequency light cycle will be the main research directions of large-scale cultivation of Chlorella in the future.
Deceleration of liver regeneration by knockdown of hepatic stimulator substance gene expression in mice
Authors: Han Lihong , Yan Bin
Published: December 2024

Hepatic stimulator substance (HSS), an active protein extracted from the liver of a newborn animal or from the residual liver after partial hepatectomy. HSS only stimulated the proliferation of hepatocytes or hepatogenic tumor cells, but had no stimulating effect on other tissue cells or non-hepatogenic tumor cells, indicating that its effect was tissue-specific. In addition, HSS can protect liver cells and reduce the damage of CCl4, galactosamine, thioacetamide and other drugs on liver cells. Although the hepatoprotective function of HSS has been understood to some extent, as a hepatogenic growth factor, the role of HSS in liver regeneration remains unclear and needs further study. To demonstrate if HSS plays a role in the regulation of liver regeneration and its possible mechanisms, we detect liver regeneration related index changes by knockdown of HSS after partial hepatectomy (PH). Results showed that knockdown of HSS lead to decreased liver regeneration, inhibit hepatocyte proliferation and impair mitochondrial. HSS can promote liver regeneration and protect liver cell function, and its protective mechanism may be related to the stabilization of liver cell membrane. In conclusion inhibition of HSS expression by shRNA during liver regeneration obviously delayed the process.
