Published: May 2023

Integrated crop–livestock systems (ICLSs) can improve the sustainability of agriculture. The configuration of an ICLS to achieve sustainable development while maintaining the effectiveness of resource utilization is complicated due to conflicts between economic performance and environmental protection. In this paper, a novel optimization model-based emergy evaluation (OMEE) method is proposed for ICLS configuration. OMEE encompasses an emergy analysis and an improved non-dominated sorting genetic algorithm II (NSGA-II) programming model. Based on the emergy analysis, the emergy economic efficiency index (EYR), emergy environmental efficiency index (ELR) and emergy sustainability index (ESI) are used for the sustainable development evaluation, and the results provided the basis for the objective function for economic and environmental equilibrium. Considering programming issues, the configured initial data and hierarchical evaluation results are integrated into the improved NSGA-II (CIHE-NSGA-II) model. This model is capable of (1) configuring the initial solution based on original farming data and (2) performing hierarchical evaluations of EYR, ELR and ESI based on bilevel programming. This exploratory approach was verified based on a real case study in northern China. The results showed that the ESI increased by 16.8% when the proposed approach was applied. This simulation research demonstrates the usefulness of CIHE-NSGA II in optimizing the allocation of resources in ICLSs, and OMEE can provide evaluation results that aid in meeting decision-making goals and configuring crop and livestock resources.

Published: May 2023

A variety of strategies intended to support environmentally friendly and resource-efficient building processes comprise sustainable construction policies. The limited number of bibliometric analyses in the field may hinder the ability to assess the efficacy and impact of research efforts, impede the potential for collaboration, and even limit the dissemination of best practices. Therefore, the present study aims to analyze the impact of published data on the topic of energy efficiency of buildings using the Web of Science core collection database. We perform a bibliometric analysis and science mapping research that assesses significant parameters for the field. A total of 28,555 papers were analyzed using the VOSviewer program. The data was divided into two periods to determine the evolution of trends in this field. The most prolific countries in this field were China, the United States, and England. Following the analysis of the collaboration maps, it was determined that there is a strong collaborative relationship between these countries in the development of papers. The most prolific papers of the first period were published in Energy Policy and Energy and Buildings, which also ranked first in the second period, followed by Energies. It was observed that the most frequent terms used in literature searches in the field differ according to the periods analyzed. In the beginning, the most frequent term was “energy efficiency and performance”, and between 2011 and 2023, the terms “applied energy” and “renewable and sustainable energy” increased considerably with technological development. The results of this research demonstrate the significant and expanding scientific interest in this area and serve as a valuable asset for researchers studying the energy efficiency of buildings.
The Implementation of a Binary Blend of Waste Glass Powder and Coal Bottom Ash as a Partial Cement Replacement toward More Sustainable Mortar Production
Authors: Babajide Olabimtan Stephen , Mosaberpanah Mohammad Ali
Published: May 2023

One way the sustainability and efficiency of concrete production can be improved is by incorporating waste by-products into the mix. This can help reduce the use of natural resources, such as river sand, and prevent the pollution of valuable land. Two specific examples of waste by-products that can be used in the concrete industry are waste glass powder and coal bottom ash. This study presents an experimental investigation that analyzes the influence of adding glass powder and waste bottom ash from 0% to 20% with a 5% interval to produce high-performance mortar for rheological, mechanical, and durability properties cured under different conditions (wet and dry) and temperatures (20 °C), and at several curative processes at 7 and 28 days. The water/cement ratio is a constant 0.35. According to the research findings, blending glass powder and coal bottom ash in the production of mortar results in a significant improvement in performance, particularly in terms compressive and flexural strength (3.4–20.8%) (1.7–20.3%), while employing a 10% WGP and 10% CBA binary blend provides a large increase in the flexural strength (10.6%). In the fire resistance test, 15% WGP and 5% CBA has the maximum bond strength at 200 °C (2.6%). In SEM pictures of WGP and CBA, it is found that the two materials have a low porosity compared to the control cement mortar. Furthermore, the study finds that 10% glass powder and 10% coal bottom ash combined with cement paste is the best percentage of waste by-products to use in the creation of high-performance mortar. This ratio was discovered to be the most successful in terms of increasing mechanical, rheological, and durability qualities.

Published: May 2023

Gunungkidul district, situated in the Karst Mountain area, represents one of the more poverty-stricken regions in Indonesia. The arid nature of this area, coupled with the scarcity of surface water, poses significant challenges to economic development endeavors, particularly in agriculture and animal husbandry. The vulnerability of the natural environment, unfavorable agro-climatic conditions, and unsuitable geographical features further hamper agricultural economic activities in the Karst Mountains of Gunungkidul. This condition causes dryland farm households to be vulnerable to food insecurity. Therefore, this study attempts to investigate dryland farm households’ food security in the Karst Mountain area and examine the associations of food insecurity using the share of household expenditure on food (SEF), energy intake levels, protein intake levels, and food security classification. Food security classification is specifically considered by two indicators, food expenditure proportion, and energy intake levels. The result showed that the number of family laborers, farming experience, household income, farm size, and production negatively impact the share of household expenditure on food. The average household energy consumption is sufficient, but the average protein consumption is less than others. Household food security in the Girisubo sub-district is still low since most households (70.09%) are undernourished, food vulnerable, and food insecure. Dryland farmer households need to get assistance from the local government or the private sector to grasp information about good expenditure management and food nutrition fulfillment in order to improve food security.

Authors: Tu Hongxing , Wang Lin , Xiao Xu
Published: May 2023

In December 2019, a novel coronavirus broke out in Wuhan City, Hubei Province, and, as the center of the coronavirus disease 2019 (COVID-19) epidemic, the economy and production throughout Hubei Province suffered huge temporary impacts. Based on the input–output and industrial pollution emissions data of 33 industrial industries in Hubei from 2010 to 2019, this article uses the non-parametric frontier analysis method to calculate the potential production losses and compliance costs caused by environmental regulations in Hubei’s industrial sector by year and industry. Research has found that the environmental technology efficiency of the industrial sector in Hubei is showing a trend of increasing year-on-year, but the overall efficiency level is still not high, and there is great room for improvement. The calculation results with and without environmental regulatory constraints indicate that, generally, production losses and compliance costs may be encountered in the industrial sector in Hubei, and there are significant differences by industry. The potential production losses and compliance costs in pollution-intensive industries are higher than those in clean production industries. On this basis, we propose relevant policy recommendations to improve the technological efficiency of Hubei’s industrial environment, in order to promote the high-quality development of Hubei’s industry in the post-epidemic era.

Published: May 2023

The comparative analysis of the effect of economic policy uncertainty on environmental sustainability is imperious as it can provide critical insights into the link between economic policies and environmental sustainability. Economic policy uncertainty may have different impacts in different economies. The present study provides a comparative analysis of the effect of economic policy uncertainty on environmental sustainability in developed and emerging economies. The study employs pooled ordinary least squares and panel quantile regression to analyze data from 2001 to 2019. Moreover, the study also compares the impact of economic policy uncertainty on environmental sustainability across two different econometric methods. It also compares the results across different quantiles of the distribution of variables. Moreover, the study includes the agriculture output, renewable energy consumption, and foreign direct investment in the model. The results show that economic policy uncertainty negatively and significantly impacts environmental sustainability as it increases GHG emissions. Moreover, agriculture output increases GHG emissions in developed economies at higher quantiles. Furthermore, the results also confirm the pollution haven hypothesis, while renewable energy consumption has a positive effect on environmental sustainability as it significantly reduces GHG emissions. The study stresses that governments should take measures to minimize economic policy uncertainty to improve environmental sustainability. In addition, effective policies to enhance openness in the policymaking process and offer long-term policy certainty and foster more stable investment conditions would encourage renewable energy and reduce GHG emissions.
Sustainable Power Grid Expansion: Life Cycle Assessment, Modeling Approaches, Challenges, and Opportunities
Authors: Byles Dahlia , Mohagheghi Salman
Published: May 2023

Electric demand is steadily increasing, hence requiring continuous investments in modernizing, and expanding power grids worldwide. Traditionally, power system planning projects have considered minimizing the costs of capacity expansion and minimizing the amount of energy not served as the main objectives. With climate change policies enforcing the decommissioning of fossil-fuel-based generation, new clean and renewable generation technologies are being considered for power system capacity expansion projects. However, the environmental impacts of energy resources are not limited to carbon emissions and their contribution to global warming. In fact, every power generation technology can result in undesired impacts during its entire life cycle, which could negatively affect air quality, water resources, material resources, and/or human health. This paper provides an overview of how to assess the sustainability of power systems and power generation technologies based on life cycle assessment (LCA). A review of LCA, as applied to power systems and generation technologies, is presented with a discussion of general findings, challenges, and limitations. A review of the literature is then provided related to how sustainability objectives are currently incorporated in power grid design and capacity expansion models. Finally, shortcomings of the current models are discussed, along with opportunities for future research.

Published: May 2023

Tree residue removal from Eucalyptus plantations after timber harvest can reduce soil functioning by reducing the organic matter input. To assess the effects of residue management systems (RMS) on soil aggregation, carbon (C) and nitrogen (N) content, and biological activities, a field trial was conducted in a commercial Eucalyptus plantation (loamy sand soil) in Mato Grosso do Sul, Brazil. The study assessed three RMS: cut-to-length (CTL), tree-length (TL), and bare litter (BL), respectively. After 21 months, undisturbed soil samples were collected and physically isolated into three aggregate-size fractions: large macroaggregates (LM), medium macroaggregates (SM), and microaggregates (MI). Results showed that these soils are mostly composed of LM (54%), and that removing harvest residues from the growing site included total organic carbon (TOC) by 28%, microbial biomass-C by 20%, fluorescein diacetate hydrolysis by 17%, and β-glucosidase activity by 26%, when compared to CTL. TL outperformed CTL for the proportion of LM and LM-associated TOC. Across fractions, a higher microbial quotient was observed in SM and MI fractions, suggesting that the TOC has higher stability inside the LM. This study suggests that leaving harvest residues on the soil should be recommended for Eucalyptus plantations, especially in low-fertility sandy soils, as it helps in maintaining the soil structure and biological activities critical for soil health and ecosystem function.

Published: May 2023

The current study investigates a cogeneration cycle of power and freshwater integrated with a solar system. The solar system is of the heliostat type, which is considered to preheat the inlet air in the combustion chamber of a 25-MW gas turbine. The waste heat of the turbine output stream is used to produce freshwater. Parameters such as the ambient temperature and solar irradiance significantly affect the system’s performance; hence, all analyses, including those pertaining to energy, exergy, economics, and environment, were conducted transiently, with a one-hour time step throughout the year so that the impacts of these effective parameters could be examined. Besides the analysis assuming a constant mass flow rate for the air entering the compressor, the calculations were repeated with the assumption of a constant volumetric flow rate to evaluate the cycle in the same conditions as those of natural gas power plants. Given the constant volumetric flow rate, for every 10-degree increase in temperature, the compressor power consumption decreased by approximately 2%. Moreover, a sensitivity analysis of the cycle performance in terms of ambient temperature was performed, and the corresponding results are presented. Finally, some correlations are presented to estimate variations in compressor power consumption and net turbine power due to temperature variations. The results demonstrate that in Bushehr, Iran, every one-degree increase in ambient temperature leads to an approximately 0.67 percentage decrease in net-generated power. In the end, the performance of the cycle was investigated under climatic conditions and solar irradiation intensities in several cities in Iran and some cities in different countries in which heliostat power plants have already been established. The results obtained in these cities were compared; it was concluded that the lowest annual cost of electricity generation is related to Isfahan in Iran, which reduces the cost of electricity generation by more than 20% (2.32 Cents/kWh) compared to the base cycle.

This study aims to evaluate the fatigue phenomenon in recycled hot asphalt mixture for an asphalt surface layer. Eight mixtures were evaluated in the laboratory, and the samples were divided into two major groups: four mixtures containing neat binder and RAP from source 1 (RAP with neat binder) and four mixtures containing SBS-modified binder and RAP from source 2 (RAP with SBS-modified binder). The levels of RAP incorporation were 0%, 10%, 20%, and 30% in relation to the total weight of the mixtures. The mixtures followed the Marshall mix design methodology. The results indicate that mixtures with polymer-modified binder presented better performance, whereas the addition of RAP slightly decreased the resistance to fatigue cracking. In terms of economic analysis, the use of RAP, for all cases, leads to a reduction in production costs due to the reduction of the binder and aggregate added, with savings of up to 14.1% in the case of 30% of RAP for the SBS binder. When evaluating the economic impact of inserting RAP and its relationship with fatigue performance in the long term, it can be observed that the type of binder added impacts the results: mixtures with SBS binder present economic gains within acceptable quality parameters up to 30% RAP insertion; for mixtures with neat binder, the percentage of up to 10% RAP is advantageous.
Analyzing the Time Spectrum of Supernova Neutrinos to Constrain Their Effective Mass or Lorentz Invariance Violation
Authors: Moura Celio A. , Quintino Lucas , Rossi-Torres Fernando
Published: May 2023

We analyze the expected arrival time spectrum of supernova neutrinos using simulated luminosity and compute the expected number of events in future detectors such as the DUNE Far Detector and Hyper-Kamiokande. We develop a general method using minimum square statistics that can compute the sensitivity to any variable affecting neutrino time of flight. We apply this method in two different situations: First, we compare the time spectrum changes due to different neutrino mass values to put limits on electron (anti)neutrino effective mass. Second, we constrain Lorentz invariance violation through the mass scale, MQG, at which it would occur. We consider two main neutrino detection techniques: 1. DUNE-like liquid argon TPC, for which the main detection channel is νe+40Ar→e−+40K∗, related to the supernova neutronization burst; and 2. HyperK-like water Cherenkov detector, for which ν¯e+p→e++n is the main detection channel. We consider a fixed supernova distance of 10 kpc and two different masses of the progenitor star: (i) 15 M⊙ with neutrino emission time up to 0.3 s and (ii) 11.2 M⊙ with neutrino emission time up to 10 s. The best mass limits at 3σ are for O(1) eV. For νe, the best limit comes from a DUNE-like detector if the mass ordering happens to be inverted. For ν¯e, the best limit comes from a HyperK-like detector. The best limit for the Lorentz invariance violation mass scale at the 3σ level considering a superluminal or subluminal effect is MQG≳1013 GeV (MQG≳5×105 GeV) for linear (quadratic) energy dependence.

Avian infectious bronchitis is a serious and highly contagious disease that is caused by the infectious bronchitis virus (IBV). From January 2021 to June 2022, 1008 chicken tissue samples were collected from various regions of southern China, and 15 strains of the IBV were isolated. Phylogenetic analysis revealed that the strains mainly comprised the QX type, belonging to the same genotype as the currently prevalent LX4 type, and identified four recombination events in the S1 gene, among which lineages GI-13 and GI-19 were most frequently involved in recombination. Further study of seven selected isolates revealed that they caused respiratory symptoms, including coughing, sneezing, nasal discharge, and tracheal sounds, accompanied by depression. Inoculation of chicken embryos with the seven isolates resulted in symptoms such as curling, weakness, and bleeding. Immunization of specific pathogen-free (SPF) chickens with inactivated isolates produced high antibody levels that neutralized the corresponding strains; however, antibodies produced by vaccine strains were not effective in neutralizing the isolates. No unambiguous association was found between IBV genotypes and serotypes. In summary, a new trend in IBV prevalence has emerged in southern China, and currently available vaccines do not provide protection against the prevalent IBV strains in this region, facilitating the continued spread of IBV.

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has caused a highly challenging and threatening situation worldwide. SARS-CoV-2 patients develop various clinical symptoms. The olfactory and taste dysfunctions are potential neurological manifestations among SARS-CoV-2 patients; however, their relationship with blood groups has rarely been investigated. This study aimed to investigate the prevalence of chemosensitive neurological disorders of smell and taste and their association with blood groups in SARS-CoV-2 patients. The present cross-sectional study was performed in the Department of Pathology, and Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia. A well-structured, self-administered questionnaire was designed and distributed through social media platforms. A total of 922 Saudi and non-Saudi adults aged 18 years or older participated in the study. Out of 922 participants, the number of people who had anosmia was 309 (33.5%), 211 (22.9%) had hyposmia, and 45 (4.8%) had dysosmia. Moreover, 180 (19.52%) had ageusia, 47 (5.1%) and 293 (31.8%) had hypogeusia and dysgeusia, respectively. Among all the participants, 565 (61.27%) had smell-related disorders and 520 (56.39%) participants had taste-related clinical symptoms. The occurrence of anosmia and ageusia was relatively high among females compared to males (p = 0.024). The prevalence of smell-related disorders was 25.0% (230) and taste-related disorders was 23.21% (214) among the study participants with blood group O compared to all other blood group (A, B, and AB) participants who have smell allied disorders 30.69% (283), and taste allied disorders 27.98% (258). The prevalence of chemosensitive neurological disorders involving impaired smell and taste was higher in SARS-CoV-2 patients. These clinical symptoms were common among the participants with blood group type O compared to all other ABO blood group types. The role of certain demographic characteristics was consistent throughout multiple studies, notably with female gender and young adults.

Background: Post-marketing vaccine safety surveillance aims to monitor and quantify adverse events following immunization in a population, but little is known about their implementation in low- and middle-income countries (LMICs). We aimed to synthesize methodological approaches used to assess adverse events following COVID-19 vaccination in LMICs. Methods: For this systematic review, we searched articles published from 1 December 2019 to 18 February 2022 in main databases, including MEDLINE and Embase. We included all peer-reviewed observational COVID-19 vaccine safety monitoring studies. We excluded randomized controlled trials and case reports. We extracted data using a standardized extraction form. Two authors assessed study quality using the modified Newcastle–Ottawa Quality Assessment Scale. All findings were summarized narratively using frequency tables and figures. Results: Our search found 4254 studies, of which 58 were eligible for analysis. Many of the studies included in this review were conducted in middle-income countries, with 26 studies (45%) in lower-middle-income and 28 (48%) in upper-middle-income countries. More specifically, 14 studies were conducted in the Middle East region, 16 in South Asia, 8 in Latin America, 8 in Europe and Central Asia, and 4 in Africa. Only 3% scored 7–8 points (good quality) on the Newcastle–Ottawa Scale methodological quality assessment, while 10% got 5–6 points (medium). About 15 studies (25.9%) used a cohort study design and the rest were cross-sectional. In half of them (50%), vaccination data were gathered from the participants’ self-reporting methods. Seventeen studies (29.3%) used multivariable binary logistic regression and three (5.2%) used survival analyses. Only 12 studies (20.7%) performed model diagnostics and validity checks (e.g., the goodness of fit, identification of outliers, and co-linearity). Conclusions: Published studies on COVID-19 vaccine safety surveillance in LMICs are limited in number and the methods used do not often address potential confounders. Active surveillance of vaccines in LMICs are needed to advocate vaccination programs. Implementing training programs in pharmacoepidemiology in LMICs is essential.
Influence of Natural Barriers on Small Rivers for Changes in Water Quality Parameters
Authors: Połeć Katarzyna , Grzywna Antoni
Published: May 2023

The occurrence of the protected species Castor fiber L., which creates a network of natural barriers for its own needs, may affect the changes in water quality parameters. This study shows changes in the water quality parameters (EC, BOD5, COD, TN, N-NH4, N-NO3, N-NO2, TP, P-PO4, Cl−, SO42−) of small rivers in eastern Poland. The results were analysed using the one-way and three-way ANOVA Tukey’s HSD post hoc test to identify the significance of the changes in the water quality parameters for habitats, seasons, and land use. All parameters, with the exception of P-PO4, met the standards of a good ecological status. The average values of P-PO4 exceeded the threshold of the good ecological status in summer and meadows. The average annual changes in the water quality parameters, with the exception of N-NH4, are characterised by a decrease in pollution. The highest concentration decrease of 57% was found for P-PO4 and 45% for TP at the sites after the barriers. The lowest concentration decrease of 5% was found for EC. In the case of N-NH4, the concentration increase was 33%. The situation was completely different in the case of removing barriers, where an increase in the concentration of pollutants of about 30% was found. Changes in the water quality were significantly influenced by the season and land use. Due to the various construction, age, and removal of the barriers, beaver habitats may positively or negatively impact the water quality. It is crucial for the improvement of the water quality to ensure the durability of the functioning of barriers and the proper use of the land.

The study of anxiety and depressive disorders has not lost its relevance for many decades, and is even more relevant due to the possibility of their development after illnesses caused by new infectious agents. Currently, anxiety and depressive disorders can be attributed not only to general medical, but also to social problems. These disorders affect all aspects of the patient's life and disrupt his/her social adaptation. Anxiety and depression are the most common mental disorders with a high incidence and have become a major public health issue worldwide. The purpose of this work was to analyze the possibility of development of depression and anxiety in students of higher medical educational institutions who had the novel coronavirus infection. The results of the study confirmed the possible relationship between the development of anxiety and depressive disorders in students in higher medical schools during the year after the COVID-19 caused by SARS-CoV-2.

Patients with small acute traumatic subdural hematomas in the compensated clinical condition can be managed conservatively and have a favorable outcome. We have analyzed our own experience of conservative management of 94 patients with small acute traumatic subdural hematomas. In 16 patients (17 %), hematoma expansion occurred in the next 2–7 days and surgical treatment was required. Significant factors of hematoma expansion are its initial maximum thickness of 8–9 mm and arterial hypertension during the observation period in the hospital. There were no lethal cases in the group of patients who required delayed surgical treatment. Clinical outcomes, both in the conservative group and in the group requiring delayed surgery, did not differ significantly; all patients were discharged with 4–5 points on the Glasgow Outcome Scale. Thus, conservative management of patients with small acute subdural hematomas is safe even in case of hematoma expansion with timely surgical intervention

Currently, against the backdrop of the common fight against the coronavirus, the issue of using plasma with specific antibodies from donors who have recovered from the coronavirus infection for transfusion to patients in the acute stage of the process has been repeatedly raised. In Russia, this practice was first resorted to in St. Petersburg, but it is too early to speak about any high efficiency of these transfusions. It is necessary to take into account the fact that in the presence of three hundred patients requiring immune plasma transfusion, the antibody titer was detected in only 12 donors. Given the circumstances, it is essential to remember the importance of donation intervals, whether it be plasma or whole blood. Failure to adhere to these intervals, the lack of regular monitoring of clinical and biochemical blood parameters in donors, and failure to comply with recommendations on diet and rest between donations can lead to decompensation of recovery processes and seriously affect the donor’s health. Rehabilitation of donors during the recovery period requires the normalization of the diet and in some cases — oral administration of iron supplements.

More than 400 million people worldwide have been affected by the novel coronavirus infection (COVID-19). Most of them suffered from the disease in the pulmonary form, but the SARS-CoV-2 virus has a tropism for other organs as well. A k ey factor in the pathogenesis of COVID-19 is the influence of the virus on angiotensin-converting enzyme 2 receptors, which are located in the epithelium of the respiratory tract, gastrointestinal tract, and other organ systems. This paper will consider the main diseases of the esophagus and stomach that have developed or aggravated against the background of COVID-19, such as gastroesophageal reflux disease, superficial exfoliative esophagitis, gastric ulcer, and others.
Honor to the blood donor. June 14 is the World Blood Donor Day

Published: May 2023

Every year on June 14, World Blood Donor Day is celebrated. 2023 will be no exception. The word «donor» itself comes from the Latin «donare» meaning «to give as a gift», because often donors give others not only blood, but also life. Donation saves thousands of people every day, but every year more and more free blood is needed. Transfusion helps to prolong life; it is an integral part of some surgical procedures during natural disasters and catastrophes. To pay respect to people who donate blood voluntarily and free of charge, as well as to attract new donors, World Blood Donor Day was created.

Of all representatives of sturgeon aquaculture, Siberian sturgeon Acipenser baerii occupies about 40% of its volume and is grown in 50 countries, including Russia. In 2018, the volume of commercial biomass production of this fish in the world was estimated at about 22–23 thousand tons [17]. In order to increase the efficiency of industrial production of this fish in aquaculture in the extreme conditions of Siberia, it is advisable to use feeds enriched with non-toxic components of natural origin, which increase the viability and productivity of objects and have no adverse affect to products quality and environment. In aquaculture, including sturgeons, the phytobiotic garlic and complex organic molecules of humic compounds are used for this purpose. In this experiment the industrial factory feeds, enriched with the humic additive Humiton from peat at a dose of 25 ml/kg of feed and/or dried garlic powder at a dose of 30 g/kg was used. The effectiveness of these feeds was evaluated for training of the rearing stock of Siberian sturgeon juveniles for maintenance in cages in winter conditions, depending on the initial weight of the objects. In sturgeons with a higher initial weight, by the end of the experiment, the use of feeds enriched with each of the components was effective in terms of safety, weight gain and improvement in the feed conversion rate FCR against the background of cold stress. In small fish, the main effect was an improvement in FCR when fed with garlic powder.

This article analyses the content of the most important component of the national agricultural industry — private subsidiary farms. The author relies upon the idea that the development of horticulture is an inexpensive and stable strategy that allows to improve the food security of households by providing them with quality and environmentally friendly personally made food. According to the estimates of the Union of Gardeners of Russia, 125 million Russians belong to families receiving products from the land they cultivate themselves, or to those going to help their relatives in summer. At the same time, according to Rosstat estimates, if the entire volume of agricultural production at actual prices in 2022 preliminarily amounted to 8.851 trillion rubles, households account for 2.071 trillion rubles at actual prices (i.e. a quarter of all products). Today, in the conditions of increasing pressure of sanctions on the agricultural sector of Russia, horticulture is of great importance for achieving the principal parameters of the country’s food security. The article shows that there is a signifi cant decrease in the number of both farms themselves and indicators of production effi ciency for personal consumption and for sale. Being a practitioner — chairman of an allotment society and a leading expert of the Federal Center for Agricultural Consulting, the author highlights the main issues, regulatory and legal restrictions that signifi cantly hinder the development of households, in particular: the inability to use the "dacha amnesty" for most allotment gardens, serious cadastral errors, the growth of abandoned land plots, as well as legislative innovations related to restrictions on keeping of farm animals and birds on garden plots.

The article deals with the theoretical foundations of the use of algorithmic trading technologies. The relevance of the study lies in the fact that in modern conditions there are more and more exchange robots, their algorithms are being improved and the technical capabilities of their application are expanding, moreover, increasing the competitiveness of exchange bots is becoming an acute problem, from the standpoint of increasing forecasting accuracy, which ensures their digital competitive advantage. The novelty lies in the fact that the study proposed a developed stock advisor based on the Random Forest Deep Learning model "Random Forest Regression". The purpose of the study is to develop an algorithm for predicting the closing price of a SiU3 dollar futures contract on the Moscow Exchange. To achieve the goal, the following tasks were set and solved: to explore the theoretical foundations for the use of ensembles of decision trees and develop an exchange advisor based on the Random Forest Regression Deep Learning model, as well as to form a VaR model for assessing fi nancial risk, in addition, to study competition in the fi eld of algorithmic trading in the stock market. The practical significance is that the results of the study can be used in practice in exchange trading. As a result, a high accuracy of the forecast was obtained, since the level of the average absolute error of the model does not exceed the value of 49.01 rubles, and the level of the maximum absolute error does not exceed the value of 162.52 rubles, while MSE (R2) is equal to –0.2573 for the option in which the share of the test sample in the dataset was 0.20.
Çin Din ve Düşünce Geleneğinde Muğlak Bir İdeal Olarak Wu-Wei: Kavramsal ve Tarihsel Bir İnceleme
Authors: ÖZALP Mürsel
Published: May 2023

Literal olarak “gayretsizlik/eylemsizlik” şeklinde tercüme edilen wu-wei, en belirgin şekliyle Lao Tzu’ya atfedilen Tao Te Ching (Yol ve Erdem Klasiği) adlı eserde geçer ve yüce Tao’nun önemli bir vasfı olarak ta-nımlanır. Ancak Lao Tzu tarafından idealize edilen bu prensibe daha önceki dönemlerle tarihlendirilen ko-runmuş Çin literatüründe de atıfların olduğu ileri sürülmüştür. Bu iddiaya göre wu-wei, Shih-ching (Şiirler Kitabı) gibi eski Çin şiirinde aristokrat beyefendi veya karizmatik genç asilzadenin tutum ve davranışların-da ete kemiğe bürünmektedir. Lao Tzu ile aynı dönemde yaşayan Konfüçyüs ve daha sonra gelen Chuang Tzu, Wang Pi ile Shen Pu-hai ve Han Fei gibi bazı Taocu teorisyen, filozof ve devlet adamları da wu-wei kav-ramını farklı şekillerde -bireysel manevi tekâmül veya siyasi-politik yönetim minvalinde- kullanmışlardır. Farklı dönem ve alanlara teşmil edilip birbirine yakın veya uzak pek çok anlam yüklenmesinin sebebi ise wu-wei’in tanımlanması ve anlaşılması zor bir kavram olmasıdır. Bundan dolayı wu-wei geçmişten günümü-ze farklı açıklamalar, sembolik, alegorik ve mecazi benzetmeler ve metaforlarla tanımlanmaya çalışılmıştır. Bu çalışmada, Taoizm özelinde manevi bir sükûnet modeli olarak resmedilen wu-wei kavramının Çin din ve düşünce geleneğindeki izleri sürülecektir

The article defines proposals aimed at improving the normative provisions of the law on discharge from criminal responsibility in view of admission by bail (the Art. 47 of the Criminal Code of Ukraine). In particular, it is proposed: a) the introduction of effective control by the state (its bodies) in compliance with the terms of the transfer of a person to bail, which provides for the supervision of the person's performance of the duties assigned to him in connection with his release from criminal liability on the basis of the Art. 47 of the Criminal Code and, at the same time, supervision over the implementation by the staff of the enterprise, institution, organization of educational measures in relation to the person who has been transferred to bail; b) consolidation in the Art. 47 of the Criminal Code, the authority of the court, in addition to the application of educational measures, which are provided for in the very request of the collective to transfer the person to bail, also to impose on the person one or more such duties: 1) to compensate property damage caused by a criminal offense; 2) comply with the requirements established by the court regarding the performance of certain actions, restrictions on communication, movement and leisure activities; 3) referral for a probationary program. The issue of the expediency of setting a bond as an additional guarantee of compliance with the terms of the transfer of a person to bail was analyzed. On the basis of the conducted research, proposals were formulated regarding amendments to the Art. 47 of the Criminal Code of Ukraine, based on the results of a survey of 90 judges and 483 prosecutors regarding the outlined problems. Implementation of the proposed changes regarding the establishment of proper control by the state in compliance with the conditions of discharge from criminal liability based on the Art. 47 of the Criminal Code must ensure the strengthening of the differentiated educational influence on persons who are transferred to bail, the establishment of additional mechanisms for the real restoration of violated rights of a victim in terms of compensation for property damage caused by a criminal offense, and the introduction of additional guarantees of the proper fulfillment of the obligations undertaken as a person trying to prove their correction, as well as by the collective of the enterprise, institution or organization. Also, the formulated proposals will contribute to increasing the effectiveness of the researched form of public participation in the fight against criminality, as well as allow to get rid of Soviet stereotypes in the perception of such a provision of criminal law as discharge from criminal responsibility in view of admission by bail.
