Published: September 2023

This in vivo study aimed to investigate the effects of a multi-component mycotoxin-detoxifying agent, containing clays (bentonite, sepiolite), phytogenic feed additives (curcumin, silymarin) and postbiotics (yeast cell wall, hydrolyzed yeast) on the antioxidant capacity, health and reproductive performance of pregnant and lactating sows challenged by mycotoxins. Eighty (80) primiparous sows (mean age 366 ± 3 days) per each of the two trial farms were divided into two groups in each farm: a) T1 (control group): 40 sows received the contaminated feed and b) T2 group (experimental group): 40 sows received the contaminated feed plus the mycotoxin-detoxifying agent, one month before farrowing until the end of the lactation period. Thiobarbituric acid reactive substances (TBARS), protein carbonyls (CARBS) and total antioxidant capacity (TAC) were evaluated as biomarkers of oxidative stress. Clinical and reproductive parameters were recorded. Our results indicate that the administration of a multi-component mycotoxin-detoxifying agent’s administration in sow feed has beneficial effects on oxidative stress biomarkers and can improve sows’ health and performance.

Published: September 2023

Understanding Influenza B virus infections is of critical importance in our efforts to control severe influenza and influenza-related diseases. Until 2020, two genetic lineages of influenza B virus—Yamagata and Victoria—circulated in the population. These lineages are antigenically distinct, but the differences in virus replication or the induction of host cell responses after infection have not been carefully studied. Recent IBV clinical isolates of both lineages were obtained from influenza surveillance efforts of the Johns Hopkins Center of Excellence in Influenza Research and Response and characterized in vitro. B/Victoria and B/Yamagata clinical isolates were recognized less efficiently by serum from influenza-vaccinated individuals in comparison to the vaccine strains. B/Victoria lineages formed smaller plaques on MDCK cells compared to B/Yamagata, but infectious virus production in primary human nasal epithelial cell (hNEC) cultures showed no differences. While ciliated epithelial cells were the dominant cell type infected by both lineages, B/Victoria lineages had a slight preference for MUC5AC-positive cells, and B/Yamagata lineages infected more basal cells. Finally, while both lineages induced a strong interferon response 48 h after infection of hNEC cultures, the B/Victoria lineages showed a much stronger induction of interferon-related signaling pathways compared to B/Yamagata. This demonstrates that the two influenza B virus lineages differ not only in their antigenic structure but also in their ability to induce host innate immune responses.

Authors: Zhang Cheng , Su Guodong , Li Xia
Published: September 2023

Socioeconomic development often leads to environmental pollution and degradation initially while, beyond a certain point, there is the potential for improvements in environmental quality. In this study, we conducted a comprehensive review of published literature and national data to investigate changes in nutrient concentrations and limitations in Poyang Lake from 1978 to 2021. Our objective was to examine the relationships between these changes and the process of socioeconomic development in the watershed. The findings revealed a rapid socioeconomic development of the Poyang Lake Watershed, showing significant changes in various indexes. For example, population, Gross Domestic Product (GDP), urbanization, grain and meat productions, sewage amount and treatment rate, and forest coverage in the watershed showed increasing trends with different fitting curves, each following distinct fitting curves such as exponential, binary, and linear models. Concurrently, the concentrations of total nitrogen (TN) and total phosphorus (TP) in Poyang Lake exhibited a linear increase over the years, surpassing eutrophication thresholds since the early 1980s. However, TN and TP have shown a decreasing trend in recent years. Notably, the lake displayed co-limitation by N and P, with TN primarily driving the N:P ratio. TN and TP showed a significant “∩” shape with the increase in GDP and urbanization, while they increased with the population. TN:TP showed an increasing pattern with GDP and urbanization but a “U” shape with the population. This research contributes significant insights into the long-term changes in nutrient concentrations, shifts in nutrient limitations, and their associations with socioeconomic development. The findings highlight the need for a balanced and strategic approach to appropriately manage both nutrients for effective eutrophication mitigation.

Published: September 2023

The Qinghai-Tibet Plateau (TP) is susceptible to climate change and human activities, which brought about drastic alterations in vegetation on the plateau. However, the trends and driving mechanisms of vegetation changes remain unclear. Therefore, the normalized difference vegetation index (NDVI) was used to analyze the spatiotemporal distribution of vegetation and the consistency of dynamic trends in the TP from 2000 to 2020 in this study. The independent contributions and interactive factors of natural and human activities on vegetation changes were investigated through the Geodetector model. The drivers of vegetation under different dry–wet zones and precipitation gradients were quantitatively separated, and the internal mechanisms of vegetation changes were discussed from multiple perspectives. The results showed that from 2000 to 2020, the NDVI had an overall increasing trend, with an increasing rate of 0.0027 a−1, and the spatial pattern was different, increasing gradually from the northwest to the southeast. Consistent improvement occurred in the central and southeastern parts of the TP, while the western and northern parts consistently deteriorated. The annual mean precipitation had the greatest explanatory power for vegetation changes (0.781). The explanatory power of the integrated effects between two factors was greater than that of individual factors. The integrated effects between annual mean precipitation and other driving factors had the strongest explanatory power on vegetation variations. The driving mechanisms of vegetation dynamics varied among different dry–wet zones, and the vegetation growth was more sensitive to the response of precipitation in arid and semi-arid climate zones. This study enhances our understanding of the intrinsic mechanisms of vegetation changes on the plateau, which can provide a reference for ecological conservation, and has implications for further prediction and assessment of vegetation ecosystem stability.

Published: September 2023

The availability of remotely sensed (RS) actual evapotranspiration (ET) provides a possibility for improving runoff prediction in ungauged basins. To develop a general practical method to improve runoff prediction by directly incorporating RS-ET into rainfall-runoff (RR) models, two modeling schemes are proposed: (i) using RS-ET as direct input; and (ii) using RS-ET as partial direct input. The principle is to use RS-ET in cases where the runoff prediction can be improved. The two schemes are compared in over 200 basins using three RR models (Xinanjiang model, SIMHYD, and GR4J) and RS-ET inverted from AVHRR, and the modeling results in ungauged basins are assessed using the spatial proximity method. Results show that: (i) it is beneficial to incorporate RS-ET into the Xinanjiang model for over 85% of the basins, but this is not the case for SIMHYD and GR4J models; (ii) further model improvements can be obtained by using RS-ET as partial direct input, and are achieved in 91.1%, 59.0%, and 53.2% of the basins for Xinanjiang, SIMHYD, and GR4J, respectively; and (iii) incorporation of RS-ET is more applicable for Xinanjiang while less so for GR4J, and the efficacy is superior for basins that are relatively arid and were originally poorly simulated. Overall, using RS-ET as partial direct input is recommended.
Application of Closed-Circuit Television Image Segmentation for Irrigation Channel Water Level Measurement
Authors: Kim Kwihoon , Choi Jin-Yong
Published: September 2023

Measuring water levels in an irrigation channel is an important task in irrigation system decision making and estimating the quantity of irrigation water supplies. This study aimed to measure water levels with image information from an irrigation channel. Images were obtained from a CCTV (closed-circuit television) camera and manually annotated to create ground-truth mask images. A comparative analysis was performed using four backbone models (ResNet-18, ResNet-50, VGGNet-16, and VGGNet-19) and two segmentation models (U-Net and Link-Net). ROIs (Regions of Interest), mostly related to the water levels, were selected for converting water pixels to water levels. The U-Net with ResNet-50 backbone model outperformed other combinations in terms of the F1 score and robustness, and selecting an ROI and using a quadratic line between water pixels and water levels showed an R2 of 0.99, MAE (Mean Absolute Error) of 0.01 m, and ME (Maximum Error) of 0.05 m. The F1 score of 313 test datasets was 0.99, indicating that the water surface was sufficiently segmented and the water level measurement errors were within the irrigation system’s acceptable range. Although this methodology requires initial work to build the datasets and the model, it enables an accurate and low-cost water level measurement.

Published: September 2023

We aimed to determine the optimal conditions for the mass culture of rotifers, which can be used as feed for cold-water fish species at low temperatures. The growth and specific growth rates (SGRs) of rotifers were assessed considering water temperature, salinity, density, dissolved oxygen (DO) levels, and the amount of Chlorella supplied as feed. The growth of rotifers was higher at 15 °C than at 10 °C and at salinities of ~11–17 psu. Initial inoculation densities of 500 and 700 individuals/mL resulted in the highest rotifer density, and SGR was highest at 100 individuals/mL. DO concentration did not significantly affect the growth and SGRs of rotifers. Enrichment with fatty acids is important to supplement the diet of cold-water fish species. Highly unsaturated fatty acid content increased with enrichment time to 14.04 ± 0.86% at 12 h and 15.58 ± 2.20% at 24 h. Thus, the optimal conditions for rotifer mass culture are a water temperature of 15 °C, salinity of 11–17 psu, initial inoculation density of 300–500 individuals/mL, DO concentration of 8 mg/L or more, and Chlorella supply at 7.5 × 1012 cells/mL. Therefore, the present study suggests optimal culture conditions of rotifers at low temperatures for breeding cold-water fish species.

Published: September 2023

A land cover map of two arctic catchments near the Abisko Scientific Research Station was obtained based on a classification from a Sentinel-2 satellite image and a ground survey performed in July 2022. The two contiguous catchments, Miellajokka and Stordalen, are covered by various ecotypes, from boreal forest to alpine tundra and peatland. Two classification algorithms, support vector machine and random forest, were tested and gave very similar results. The percentage of correctly classified pixels was over 88% in both cases. The developed workflow relies solely on open-source software and acquired ground observations. Space organization was directed by the altitude as demonstrated by the intersection of the land cover with the topography. Comparison between this new land cover map and previous ones based on data acquired between 2008 and 2011 shows some trends in vegetation cover evolution in response to climate change in the considered area. This land cover map is key input data for permafrost modeling and, hence, for the quantification of climate change impacts in the studied area.
Football Culture and Domestic Violence: Dissecting the Link among a Focus Group of Non-Abusive Youth Football Fan’s
Authors: Lindsay Jessica , Willmott Dominic , Richardson Emma
Published: September 2023

Increased reports of domestic violence and abuse (DVA) have been identified following football games. Yet, the relationship between DVA and football culture remains qualitatively underexplored. To better understand this phenomenon, we conducted a focus group with male, non-abusive football youth fans to gain their perceptions of why domestic violence increases following football matches in England. Using thematic analysis, we present a unique insight into the link between DVA and football culture. The findings align with previously identified risk factors for DVA, including the role of alcohol consumption, gambling, and other violent behaviours. We also identified game-specific (e.g., the intensity of winning or losing) and individual factors (e.g., previous exposure to violence and awareness of what constitutes DVA) as heightening the effects of these cultural behaviours, alongside an increased sense of identity with ‘football culture’ after attending a game. We conclude by considering the implications of these findings for policy and practice, such as considering placement of advertising campaigns during matches to increase awareness, increasing threats of punishment and considering the scheduling of matches to reduce triggers of such cultural, and often violent, behaviours associated with football fandom. In addition, we call for further research in this area.
Degradation Mechanisms of a Li—S Cell using Commercial Activated Carbon

Published: September 2023

In lithium–sulfur (Li–S) batteries, encapsulation of sulfur in activated carbon (AC) materials is a promising strategy for preventing the dissolution of lithium polysulfide into electrolytes and enhancing cycle life, because instead of solid–liquid–solid reactions, quasi-solid-state (QSS) reactions occur in the AC micropores. While a high weight fraction of sulfur in S/AC composites is essential for achieving a high energy density of Li–S cells, the deterioration mechanisms under such conditions are still unclear. In this study, we report the deterioration mechanisms during charge–discharge cycling when the discharge products overflow from the AC. Analysis using scanning electron microscopy and energy-dispersive X-ray spectrometry confirms that the sulfur in the S/AC composites migrates outside the AC as cycling progresses, and it is barely present in the AC after 20 cycles, which corresponds to the capacity decay of the cell. Impedance analysis clearly shows that the electrical resistance of the S/AC composite and the charge-transfer resistance of QSS reactions significantly increase as a result of sulfur migration. On the other hand, the charge–discharge cycling performance under limited-capacity conditions, where the discharge products are encapsulated inside the AC, is extremely stable. These results reveal the degradation mechanism of a Li–S cell with micro-porous carbon and provide crucial insights into the design of a S/AC composite cathode and its operating conditions needed to achieve stable cycling performance.

Published: September 2023

Recently, game-based learning has been increasingly popular in education to increase the colleges' student participation in learning activities, especially conducting tests. This study examined the college students' learning experiences by conducting a pretest and posttest through the Kahoot application. This study recruited four college students aged twenty to twenty-two to participate who were selected purposely to provide "information-rich" cases. Focus group discussions were conducted to obtain rich information to solve the research question and analyzed through four steps: analyzing interview data, writing memos, creating the final report, and organizing the structure. The findings highlight three themes to describe such as (1) the implementation of game-based learning, (2) Students' challenges using Kahoot, and (3) The positive students learning outcomes of using Kahoot. The implementation of Kahoot can create a more attractive, exciting, and quality test atmosphere because students answer questions purely within a limited time setting. This activity also encourages students to repeat the previous material to think faster in submitting answers to the Kahoot!

QUALITY OF WORKING LIFE AND JOB SATISFACTION OF RUSSIAN WOMEN AND MEN: A COMPARATIVE ANALYSIS
Authors:   Institute of Economics, Russian Academy of Sciences, Moscow, Russia, Chernykh E.A.
Published: September 2023

The relevance of the study is due to the fact that the quality of working life (QWL) is an important factor determining the effective implementation of the labor potential of employees, which, in turn, leads to a high quality of life. The object of the research is women and men employed in the Russian labor market. The subject is a comparison of the quality of working life and job satisfaction of working women and men in the Russian labor market. The purpose of the paper is to quantitatively and qualitatively assess the individual parameters of the QWL of Russian workers, as well as to analyze the job satisfaction of those employed in dynamics and depending on gender; to establish by what parameters of the QWL there is a difference between the sexes and how large it is. The main research method was a comparative analysis of microdata from the Russian Monitoring of the Economic Situation and Health of the Population of the National Research University Higher School of Economics (RLMS-HSE) for 2000-2021, and data from the Comprehensive Surveillance of Living Conditions of the Population (CSLS-2020). The author put forward a hypothesis about a "gender paradox" in Russia and the presence of different factors underlying job satisfaction for men and women, as well as the presence of gender inequality in a number of QWL indicators. Based on the results of the study, it was concluded that the gender paradox persists in Russia; the hypothesis that JS factors for men and women differ was not confirmed. The area of application of the results is the development of theoretical, methodological, and instrumental approaches to measuring the differences between the parameters of QWL of men and women, the improvement of employment policy, the improvement of working conditions to improve QWL, and the development of appropriate strategies.
NEUTRON-PHYSICAL CALCULATION OF THE VVER-1000 ON MOX-FUELED REACTOR
Authors: Egorov Mikle , Blinnikov Alexander
Published: September 2023

The use of mixed uranium-plutonium fuel in thermal reactors makes it possible to effectively use highly toxic weapons-grade plutonium for peaceful purposes. The world's reserves of such plutoni-um are a serious problem. The use of this fuel in thermal reactors significantly reduces the amount of enriched uranium needed, as well as to dispose of plutonium-239. The plutonium processed in this way can be reused in fast reactors. In that way, a significant part of nuclear waste can be used in the process of energy release, and the number of potential radioactive waste that would otherwise be buried in the soil will also decrease. The paper presents the results of the neutron-physical calculation of the VVER-1000 reactor on mixed uranium-plutonium fuel for three fuel assemblies: 30%, 50% and 70% MOX fuel from the total amount of the produced substance. The total enrichment is 5%, which will not make critical changes to the reactor operation. Effective multiplication coefficients are obtained for all variations in several approximations: the 4-factor method, the multigroup approximation. The neutron spectrum for the multigroup approximation is obtained. Xenon and samarium poisoning of the reactor was calculated. The analysis of the kinetics of the reactor and the change in the neutron flux at different input reactivity is presented. The possibility of using the selected assemblies on real power plants and the degree of plutonium reproduction during reactor operation are evaluated

This review of the literature examines the use of antiepileptic medications and how they relate to gut microbiota. Relationships exist between the makeup of the intestinal microbiota and the development and execution of the most fundamental physiological processes. Additionally, it affects the functioning of the central nervous system (CNS) by interacting with the microbiota-intestine-brain axis. The use of pharmaceutical medication is one of the factors that can alter the composition of the gut microbiota. When treating epilepsy, various drug types are used, each with a different mechanism of action. Among the medications in question are to piramate, primidone, phenytoin, carbamazepine, and phenobarbital. The similarity in structure and function between enteric and nerve cells establishes the connection between the brain and the gut. Valproic acid significantly reduced intestinal inflammation in research involving rats with colitis. Its limited ability to treat seizures in these circumstances may be due to the enterocytes limited ability to absorb this medicine. The study came to the conclusion that colitis patients and people with healthy gut, brain, and microbiota interactions typically respond better to antiepileptics and anticonvulsants than people with imbalances in this axis. These imbalances can result in a lower seizure threshold and an increased frequency of epileptic seizures.
Processing, characteristics and applications of expanded grains

Published: September 2023

The popping and puffing are adiabatic expansion process in which the grains are exposed to high temperature for short time. The heat increases vapour pressure inside the grain leading to rupture of outer shell with expansion of starchy endosperm to several folds creating a crispy and aerated puffed snack. Conventional puffing methods use hot air, oil and sand as medium of puffing, whereas non-conventional puffing methods make use of microwave, fluidized air and pressure differential in system. Although it is commonly believed that processing conditions solely influence the quality of expanded grains, many other variables such as physical, chemical and genetic characteristics of grain, post-harvest handling practices, storage conditions and pre-treatments can also largely affect quality indices of expanded grains.  As exposed to heat for only short time, expanded grains retain majority of nutrients and even improved digestibility and nutrient bioavailability traits. Flour obtained by milling of expanded grains exhibit desired functional properties expected in bakery products. This paper briefly discussed the factors influencing puffing quality and effects of puffing on physicochemical and morphological characteristics of grain along with its applications.
Research on the Rice Bran Oil – Flammability Tests on a High Temperature Surface
Authors: ȘOLEA Liviu Cătălin , CREȚU Romică
Published: September 2023

In this work rice oil was tested when it is dripped onto a high temperature surface. The tests conducted determined the lowest temperature at which rice oil ignited and the highest temperature at which rice oil did not ignite in three tests conducted at the same temperature. The results of this study show that the values of the evaluated temperatures are of major importance regarding the use of rice oil as an eco-friendly lubricant. Thus, the highest temperature at which rice oil did not ignites is 465 °C, while the lowest temperature at which rice oil ignited is 470 °C. Moreover, at the end of the 8 tests performed, part of the oils collected in the tray of the installations used in the present study were subjected to spectrophotometric tests. Based on the obtained data, the transmittance spectra were plotted and the trichromatic components and coordinates were calculated, as well as the colour differences of the tested oils.

The generic name of the washing head will be FA 100.We use 3D printing technology because, on the one hand, it is technically possible to make the part and on the other hand, for economic reasons. It is approximately ten times cheaper to make the part through 3D printing than through conventional technologies.
Limit Values of Dissolved Nutrients for the Assessment of Eutrophication in the Northeastern Mediterranean Rivers
Authors: AKÇAY İsmail , ÖZBAY Özgür
Published: September 2023

In this study, an attempt was made to determine limit values of dissolved nutrients for assessing trophic status and water quality of Northeastern Mediterranean Rivers from the previously published nutrient data sets. Study findings indicated that the oligotrophic river waters should have concentrations of total phosphorus, orthophosphate, ammonium and total nitrogen less than 0.13 mg/L, 0.07 mg/L, 0.11 mg/L and 0.90 mg/L, respectively. The proposed limit values defining oligotrophy, mesotrophy and eutrophy were different than the values reported by the Surface Water Quality Regulation and the commonly used reference values. These discrepancies were probably due to distinct physical and biochemical characteristics of the rivers. For defining threshold and reference values of dissolved nutrients, new approaches, such as modeling studies, are needed to produce more sensitive assessment tools for sustainable management of NE Mediterranean Rivers.
