Purpose of the study: the concept of complex endoscopic treatment of refractory benign cicatricial strictures of the esophagus and esophageal anastomoses is outlined, including the methodology of long-term planned supportive bougienage with intramural injections of glucocorticosteroids based on our own extensive experience. The results of an analysis of immediate and first long-term results in this group are presented, as well as detailed recommendations for the management of patients after interventions. Materials and methods. For the period from 2013 to 2023 in the endoscopic department of the Federal State Budgetary Institution “Petrovsky National Research Center of Surgery” 70 patients with refractory cicatricial strictures of the esophagus and anastomoses underwent complex endoscopic treatment, including the main course and long-term planned supportive bougienage, supplemented with intramural injections of Dexamethasone and triamcinolone according to the protocol we developed. Results. Of the total number of patients, 16 (23%) patients, after one or several courses of intramural steroid injections, did not have restenosis for 1 year or more, and 38 (54%) patients required no more than 3 sessions of prophylactic bougienage. In 49 (70%) patients, the duration of treatment was less than 1 year, and the average number of bougienage sessions was from 11 to 20. Conclusion. During the endoscopic treatment of patients with esophageal stenoses of various etiologies and strictures of the esophageal anastomoses, it is very important to assess the refractoriness of the narrowing at an early stage and determine the indications for intramural injections of glucocorticosteroids. Only if all recommendations and a regimen of long-term planned supportive bougienage are followed is it possible to achieve lasting stabilization of the lumen in the narrowing zone and avoid recurrence.
Automatic identification of streamlined subglacial bedforms using machine learning: an open-source Python approach
Authors: Abrahams Ellianna , McKenzie Marion , Pérez Fernando , Venturelli Ryan
Published: June 2024

Subglacial processes exert a major control on ice streaming. Constraining subglacial conditions thus allows for more accurate predictions of ice mass loss. Due to the difficulty in observing large‐scale conditions of the modern subglacial environment, we turn to geologic records of ice streaming in deglaciated environments. Morphometric values of streamlined subglacial bedforms provide valuable information about the relative speed, direction, and maturity of past ice streams and the relationship between ice streaming and subglacial erosion and deposition. However, man‐ ually identifying streamlined subglacial bedforms across deglaciated landscapes, sometimes in clusters of several thousand, is an arduous task with difficult‐to‐control sources of variability and human‐biased errors. This paper presents a new tool that utilizes a machine learning approach to automatically identify glacially derived streamlined features. Slope variations across a landscape, identified by Topographic Position Index, undergo analysis from a series of supervised machine learning models trained from over 600,000 data points identified across the deglaciated North‐ ern Hemisphere (McKenzie et al. 2022). A filtered dataset produced through the combination of scientifically driven preprocessing and statistical downsampling improved the robusticity of our ap‐ proach. After cross‐validation, we found that Random Forest detected the most true positives, up to 94.5% on a withheld test set, while an ensemble average of models provided the highest stability when applied within the range of applicable datasets. We build these models into an open‐source Python package, bedmap, and apply it to new data in the Green Bay Lobe region, finding the general ice flow direction and average streamlined subglacial bedform elongation with minimal effort. This type of open, reproducible machine learning analysis is at the leading edge of glacial geomorphol‐ ogy and will continue to improve with integration of newly acquired and previously collected data.
Modeling the Impact of Storm Surge Flooding and Associated Costs on North Carolina Coastal Region Corn and Soybean Fields via Remote Sensing
Authors: Chen Peggy
Published: June 2024

Hurricane and tropical storm-driven storm surge flooding places coastal farmlands at high risk of crop damage and soil salinization. The damage can total to millions of dollars in costs and force farmers to abandon coastal fields. Additionally, many agricultural, and often rural, areas are unable to access accurate and reliable flood-risk projection maps and analyses that can inform prevention and mitigation strategies. This study developed a simplistic methodology for cropland loss analysis that can be utilized by those in regions without advanced GIS specialists, but still wish to explore flood analysis. While similar studies have been conducted in the past, few focus on North Carolina, and most use techniques that require years of expertise and formal training to be able to execute. Soybean and corn, two crops that are critical suppliers to the state economy and have a multitude of uses, were selected to be analyzed. Soybean and corn fields in three of North Carolina’s coastal counties were evaluated under various storm surge models. Cropland maps were taken from CroplandCROS, a geospatial database maintained by the United States Department of Agriculture (USDA) for the selected counties. Storm surge models of one, three, five, and nine meters in elevation were overlaid with crop data, and total farmland area submerged by the models was calculated. Models were validated with official flood risk projections and high-risk cropland areas were identified. Under the highest storm surge model, an estimated 672,226,470 m2, or 86.775% of farmland across all three counties is at risk of flooding. Economic losses were calculated under each model, resulting in damages as high as $135,148,007.30. Further research will be conducted to include more data layers in order to produce more holistic risk projections and enhance the accessibility of flood risk assessment, as well as improving the accuracy and efficiency of the current methodology.
A Comparison of Pragmatic and Scalable Strategies to Assess Fidelity to Cognitive Processing Therapy in Routine Care Settings
Authors: Stirman Shannon Wiltsey
Published: June 2024

Fidelity monitoring is crucial for successful implementation of evidence-based practices, buttraditional methods such as observation and video recording are impractical for routine mentalhealth care due to their high resource demands. A reliable, low-burden fidelity (adherence andcompetence) assessment can be helpful in improving the sustained implementation of cognitivebehavioral therapies (CBTs). This study evaluated two pragmatic alternatives to the time andcost-intensive “gold standard” observer ratings based on session recordings to assess fidelity inCognitive Processing Therapy (CPT). We assessed the feasibility of clinician-completedadherence checklists and ratings of clinical worksheets that were completed during sessions inpublic and private mental healthcare settings by a diverse sample of patients with significanttrauma histories and their therapists. We also examined whether fidelity ratings using theseapproaches were associated with observer ratings of fidelity and with subsequent PTSDsymptom change. Results indicated high overall rater agreement for adherence and competenceon CPT worksheets and session recordings. We found significant associations among traditionalobserver ratings of adherence and our two low-burden alternatives for assessing adherence.Clinician-completed adherence checklists were also associated with subsequent symptomchange. Checklists and worksheets required substantially less time to rate than sessionrecordings. Overall, checklists and worksheets emerged as reliable and feasible methods forfidelity assessment, potentially diminishing the necessity for time- and labor-intensive fidelityratings based on session recordings. Our findings suggest a scalable approach for integratingfidelity monitoring and support into policies aimed at enhancing the accessibility andeffectiveness of evidence-based care.
The Role of Social Media in Teenage Lifestyle Change (G-Z)
Authors: Amalia Salma
Published: June 2024

Social media has become an important part of everyday life, especially among teenagers. This research examines the role of social media in changing teenagers' lifestyles, including social, cultural and psychological aspects. Social media provides a platform for teenagers to communicate, share information and express themselves, but it also greatly influences their lifestyle. The research results show that social media use can influence teenagers' communication patterns, self-esteem, and cultural and consumption habits. On the one hand, social media can increase connections and access to information, but on the other hand, it can cause problems such as addiction, online bullying and mental health disorders. Therefore, it is important for parents, educators and policy makers to understand these dynamics and take appropriate steps to maximize the positive benefits of social media and minimize the negative impact on teenagers' lifestyles
Complex associated factors of depression in general population
Authors: rezapour
Published: June 2024

Depression is a common and serious mental phenomenon that affects many people. Previous studies have mostly focused on the simple and direct association between depression and other factors, ignoring the potential interactions and complexities. This study uses data from the National Health Interview Survey (NHIS) on noninstitutionalized US adults to explore the possible complex and multidimensional nature of depression by considering all pairwise interaction terms across variables. Some of the findings are the association between sexual orientation and depression is moderated by how often individuals have trouble relaxing or feel on edge; the association between education level and depression is influenced by how worried they are about paying medical bills and their age; and various pain variables are associated with higher levels of depression, such as back pain and sleeping problem. The study concludes that depression is a complex phenomenon that requires careful consideration of its associated factors. It also suggests that special attention should be given to the lower educated, younger, smokers, people with pain and sexual minority groups.
Moderation analysis in two-instance repeated-measures designs: Probing methods and multiple moderator models
Authors: Montoya Amanda Kay
Published: June 2024

Moderation hypotheses appear in every area of psychological science, but the methods for testing and probing moderation in two-instance repeated measures designs are incomplete. This article begins with a short overview of testing and probing interactions in between-participant designs. Next I review the methods outlined in Judd, McClelland, and Smith (Psychological Methods 1; 366–378, 1996) and Judd, Kenny, and McClelland (Psychological Methods 6; 115–134, 2001) for estimating and conducting inference on an interaction between a repeated measures factor and a single between-participant moderator using linear regression. I extend these methods in two ways: First, the article shows how to probe interactions in a two-instance repeated measures design using both the pick-a-point approach and the Johnson–Neyman procedure. Second, I extend the models described by Judd et al. (1996) to multiple-moderator models, including additive and multiplicative moderation. Worked examples with a published dataset are included, to demonstrate the methods described throughout the article. Additionally, I demonstrate how to use Mplus and MEMORE (Mediation and Moderation for Repeated Measures; available at http://akmontoya.com), an easy-to-use tool available for SPSS and SAS, to estimate and probe interactions when the focal predictor is a within-participant factor, reducing the computational burden for researchers. I describe some alternative methods of analysis, including structural equation models and multilevel models. The conclusion touches on some extensions of the methods described in the article and potentially fruitful areas of further research.

Published: June 2024

In this study, we aimed to expand the domain specificity of grit by exploring it in the realm of parenting. Parental grit was defined as parents’ inclination to demonstrate perseverance, sustained passion, and adaptability in pursuing long-term parenting goals. With longitudinal data from 1,373 U.S. parents, we developed and validated the Parental Grit Scale (PGS) in three phases: item development and revision, establishment of factor structure, and examination of criterion-related and incremental validity. The PGS exhibited a three-factor structure and (partial) scalar measurement invariance across genders, the status of the child’s special needs, and measurement occasions. The PGS demonstrated moderate temporal stability. We found evidence of its validity in predicting parental emotional exhaustion, self-efficacy, autonomy support, and parents’ perceptions of children’s school well-being. Parental grit explained variance in these outcomes beyond domain-general grit and conscientiousness. The PGS has sound psychometric properties and is a valuable measure in the parenting domain.
Modeling probabilistic reduction across domains with Naive Discriminative Learning
Authors: Stein Anna Sophia , Tang Kevin
Published: June 2024

The predictability of a word modulates its acoustic duration. Such probabilistic effects can compete across linguistic domains (segments, syllables and adjacent-word contexts e.g., frequent words with infrequent syllables) and across local and aggregate contexts (e.g., a generally unpredictable word in a predictable context). This study aims to tease apart competing effects using Naive Discriminative Learning, which incorporates cue competition. The model was trained on English conversational speech from the Buckeye Corpus, using words as outcomes and segments, syllables, and adjacent words as cues. The connections between cues and outcomes were used to predict acoustic word duration. Results show that a word's duration is more strongly predicted by its syllables than its segments, and a word's predictability aggregated over all contexts is a stronger predictor than its specific local contexts. Our study presents a unified approach to modeling competition in probabilistic reduction.
Experience in sports and music influences implicit motor imagery
Authors: Bek Judith , O'Farrell Richard , Cooney Sarah Maeve
Published: June 2024

Background. Motor imagery (MI) can be an effective strategy for learning and enhancing movement or as an alternative training modality when physical practice is compromised. Individual differences in MI ability are widely documented but the role of experience in different activities in influencing MI is not well understood. The present study examined how experience in activities associated with the use of MI influences implicit and explicit MI. Methods. Participants completed a hand laterality judgement task (N=125) and a MI questionnaire (MIQ-3; N=89) online. These implicit and explicit measures of MI were analysed in relation to frequent experience in individual sports/exercise, team sports, dance, and playing a musical instrument. Results. The majority of participants reported using both visual and kinesthetic MI within their activities. Across activities, frequent experience was associated with more accurate hand laterality judgement, as well as increased biomechanical constraint effects, particularly for hands viewed from the palm. In relation to the different activity types, significant effects were found for individual and team sports and music. No effects of experience were found for explicit MI (MIQ-3). Conclusion. Experience in activities that utilise MI influences implicit MI strategies more than explicit MI ability. Activity-specific effects on MI may reflect differences in kinesthetic and visual experience of the different hand surfaces.
Signed Consent Revisited
Authors: de Cheveigné Alain
Published: June 2024

It is common in behavioural sciences to require subjects of an experiment to sign an informed consent form. The form explains the procedures and risks, and the signature certifies that the subject is aware and consents. The motivation for this requirement – protection of the subject – is noble and uncontroversial, but the implications do not all align with that motivation. I argue that the subject's signature is often unnecessary. Signature commits – rather than protects – the subject, and produces a trace with sensitive personal information that prevents full anonymization and puts a burden on the investigator and institution to protect and curate that information. Trust based on shared norms is replaced by a contract that has to cover every eventuality and thus may be hard to understand. Those downsides are absent when a signature is not gathered. Signed consent might protect the investigator or institution, but that is distinct from protecting the subject. The decision to gather a signature should be justified to the IRB by the investigator, rather than the decision to not gather it. A well-designed informed consent form, unsigned, can protect both subject and investigator.
Review of Strategies and Policies for Participation in Global Value Chains
Authors: Dutta Sourish
Published: June 2024

This article reiterates the importance of understanding and addressing the strategic inquiries and potential responses in the context of global value chain (GVC) participation. Policymakers must address these crucial matters to engage in GVCs effectively. Governments aspiring to participate in GVCs must focus on determining which tasks to prioritise and exploring various forms of GVC governance. The challenges and opportunities of establishing top-notch GVC connections and fostering a favourable environment for foreign assets are significant for countries looking to integrate into GVCs. While navigating power dynamics and supply chain risks, these efforts can attract suitable foreign investors, enhance market connectivity, and develop high-quality infrastructure and services, all of which can lead to significant economic growth and development. The potential benefits of GVC participation are vast, and by understanding and addressing the strategic inquiries and possible responses, policymakers can take control of the situation and pave the way for a prosperous future.

Published: June 2024

This study investigates the teaching strategies implemented at Madrasah Ibtidaiyah Negeri 3 Banjarmasin to enhance students' ability to read the Qur'an. Employing a qualitative research approach, the study utilizes descriptive methods to analyze how these strategies are executed within the classroom setting. Primary data were gathered through structured observations and in-depth teacher interviews, supplemented by a literature review to contrast current findings with established pedagogical practices. This comprehensive approach aimed to provide a nuanced understanding of the instructional methodologies, their implementation, and the contextual factors affecting their efficacy. The findings indicate combining traditional and contemporary teaching strategies significantly improves students' Qur'anic reading abilities. Repetitive recitation and group readings are pivotal in fostering phonetic skills and memorization. At the same time, incorporating digital tools and visual aids enhances engagement and aids in understanding complex Tajweed rules. Role-playing exercises have also proven to boost students' confidence and interactive learning. However, challenges such as inconsistent student engagement levels, limited technological resources, and large class sizes have been identified as substantial obstacles. These issues highlight the need for continued institutional support and resource allocation to optimize the effectiveness of teaching strategies and ensure comprehensive learning outcomes for all students.
Монастирі та чернецтво Київської єпархії синодального періоду: регламентація діяльності в системі російського церковного законодавства
Authors: Чучалін Олександр
Published: June 2024

The article aims to specify the status of Orthodox monasteries and monasticism in the Kyiv eparchy between the 19th and early 20th centuries within the framework of the then-existing Russian church legislation. Research methodology is grounded in the principles of historicism and scientific objectivity, using critical, systematic and comparative analysis of sources. These methods and principles have enabled a comprehensive study of various phenomena in their dynamics and totality, taking into account all conflicting factors. By employing these diverse methods, the study has traced the impact of Russian church legislation on events and processes regulating the activities of monasteries and monasticism in the Kyiv eparchy during the synodal period. Conclusions. The 18th-century reforms in the Russian Empire’s ecclesiastical sphere designated the Holy Governing Synod as the legislative authority over the Orthodox Church, fully subordinating it to the Russian imperial government. During this century, church legislation was established, which, with minor modifications and additions, remained in effect throughout the 19th and early 20th centuries and applied to Ukrainian Orthodox eparchies. The 18th century marked a period of profound and comprehensive transformations in the history of monasteries and monasticism, characterized by strict regulation of monastic life, daily routines and the rights of the inhabitants. The primary feature of church-state relations in the 19th and early 20th centuries was the state’s total control over the Church’s affairs. The Holy Synod controlled matters such as the establishment of new monasteries, granting them status, accepting individuals into monasticism and determining the number of monastics. The monasteries of the Kyiv eparchy during this period were managed by the eparchial bishop and were entitled to elect an abbot, who was then approved by the Holy Synod through its decree. Monasteries, both male and female, were classified into three categories, either communal or non-communal, with a clearly defined monastic staff determined by the Synod.

Published: June 2024

The purpose of the article is to analyze the prerequisites, reasons and circumstances of the establishment of one of the oldest educational institutions in Ukraine, and to characterize the quality of its teaching staff. The research methodology is based on a combination of general scientific and special historical methods and adherence to the main principles of historical research: historicism, objectivity, systematicity in the process of processing archival sources and documents and preparing conclusions. The scientific novelty is that, for the first time, a set of archival sources related to the history of the First Boys' Gymnasium in Zhytomyr has been thoroughly processed, the historiography of the problem has been characterized, and the process of the foundation and formation of this educational institution, the formation of the teaching staff, has been followed in detail. For the first time, biographical information about the teachers of the gymnasium from the initial period of its existence is presented. New archival sources were introduced into scientific circulation. Conclusions. The establishment of the First Boys' Gymnasium in Zhytomyr took place in the context of a change in the national policy of tsarism towards the Poles after the suppression of the Polish uprising of 1830-1831. By creating a network of Russian-language educational institutions, the tsarist authorities aimed to overcome Polish influence on the territory of the Volyn Governorate and implement the imperial Russification policy in the region. The Boys' Gymnasium in Zhytomyr, founded in 1833, is one of the oldest educational institutions in Ukraine and one of the first (after Kyiv and Nizhyn) to train future scientists for the newly established Kyiv University. Using the example of the First Boys' Gymnasium in Zhytomyr, we state that in the initial period of formation of gymnasium education in Ukraine, turnover of teaching staff, their flow from one educational institution to another, was characteristic. By transferring teachers from the Zhytomyr Boys' Gymnasium to St. Volodymyr University, the problem of staff shortage in the latter was solved.

The purpose of the study is to analyze the problem of juvenile delinquency in the 1970s in a regional context, using the example of Zhytomyr region and the measures of their prevention by the relevant state authorities. The methodological basis of the research is the methods of analysis and synthesis, comparative, statistical (to characterize juvenile delinquencies, their dynamics) methods; the principles of objectivity, scientific, and historicism were also used, which contributed to a more impartial and comprehensive analysis of the mentioned problem and period. The scientific novelty of the study consists of a comprehensive analysis of the delinquency problem among the minors in Zhytomyr region in the 1970s, based on archival sources (reports of relevant authorities). Conclusions. For the period of the 1970s in the social sphere of the Ukrainian SSR, one of the difficult tasks of the authorities was solving the problem of the delinquency among the minors. We considered the regional aspect of the problem, using the example of Zhytomyr region. In the mentioned period, offenses among the minors tended to increase, which was primarily due to the work of the relevant authorities, schools, vocational schools, which were supposed to control the teenagers’ behavior. The analysis of the juvenile delinquencies shows that crimes against citizens' property, hooliganism and rape were mainly committed. The tendency to commit group crimes intensified. Reports and resolutions of the relevant authorities (regional executive committee, juvenile commissions) show that the problem of juvenile delinquency was quite urgent in the districts of Zhytomyr region. It should also be noted that inspections of the juvenile commissions’ work revealed their insufficiency and formal attitude to solving those problems. The work of law enforcement agencies was also insufficient. The authorities proposed a number of measures to prevent delinquency among teenagers, but they were not always effective. The measures in educational sphere were also predominant. The problem of youth’s leisure was supposed to be solved among others. At the same time, the authorities also provided anti-religious upbringing of teenagers. Regional problems of the juvenile delinquency in Ukraine during the transitional period (years of “perestroika” 1985-1991) require further research.

The purpose of the article is a comprehensive analysis of the study of parks as monuments of landscape art in Vinnytsia region. Attention is focused on historical and cultural tourism, the purpose of which is to visit places related to history and historical heritage, which includes such objects as palace and park ensembles, historical buildings, and natural monuments of the native land.  The research methodology is based on the principles of historicism, scientific objectivity, and systematicity. The purpose and objectives of the study led to the use of general scientific and special historical methods. The former include the methods of analysis and synthesis (of historical facts and sources), comparison and generalization in drawing conclusions. Among the historical methods is the chronological method, which allowed us to study the process of development of landscape gardening in Ukraine and in Vinnytsia region in chronological order. We also used the following methods: regional (which allowed us to trace the regional peculiarities of the region), problematic-chronological, comparative-historical. The scientific novelty of the study is that the information about parks as monuments of landscape gardening art of Vinnytsia region is comprehensively systematized. The main objects of garden and park tourism of national and local importance are characterized. Conclusions. Parks adorn the Vinnytsia land, have great natural, historical, scientific, educational, recreational, tourist and aesthetic significance, and are an integral part of the cultural heritage of our people. For this reason, they should be considered as important objects of tourist activity in the region. The article covers the history of the parks: Antopilskyi, Verkhivskyi, Nemerchenskyi, Nemyrovskyi, Obodivskyi, Tyvrivskyi, Cherniatynskyi, Pecherskyi and Tulchynskyi. Each of these parks-monuments of landscape art has its own past, associated with historical events, prominent personalities who visited it, legends and stories. The parks have preserved valuable plantings and architectural and artistic monuments that are important not only historically but also have a certain significance for contemporary practice. The main purpose of parks-monuments of landscape art is to preserve, maintain and restore park landscape compositions, as well as to conduct excursions and public recreation. Their territories can also be used for scientific research. They combine environmental protection functions with historical, tourist, cultural, and aesthetic ones. That is why they deserve special attention, care, maintenance and protection.

The last barrier to the release of radioactive elements into the environment in the event of an accident at a nuclear power plant is hermetic fencing (HF). After each scheduled preventive repair, leak tests are carried out to confirm the ability of the system to perform its functions. The tests consist of five stages (vacuuming, air injection, parameter stabilization, integral leakage measurement and pressure relief). A mathematical model of the state of the environment in the HF is developed, which consists of differential equations of energy balance, material balance and temperature change in materials of passive heat absorbers at non-stationary thermal conductivity. The model takes into account the evaporation of steam from the spent fuel pool. The system of differential equations is solved by the Runge–Kutta–Fehlberg method. The adequacy of the model was checked on the basis of comparison of the calculation results with the data of the test report of the HFS at the 4th unit of the Rivne NPP. In the process of stabilizing the parameters, the rate of temperature change almost coincides with the full-scale data. To shorten the stabilization stage, it is proposed to regulate the air temperature at the outlet of the compressor through the use of an ejector, which will suck in the required amount of ambient air with a lower temperature. It is shown that with a difference between the temperature of the discharged air and the temperature in the HF of 0.5 °C, stabilization is achieved in 30 minutes.
Comparison of Heat Pump Location Options for Hot Water Supply from NPP
Authors:   Odesa National Polytechnic University, Ovеrchenko A. O. , Leus V. I. , Kravchenko V. P.
Published: June 2024

Fuel consumption for heat supply makes up about a third of the total amount of fuel and energy resources consumed in the country, and this value is twice as large as the amount of fuel consumed for electricity production. This means that in order to solve the problems related to climate change, it is necessary to use nuclear power plants (NPP) more widely in the direction of heat supply. The way to reduce heating costs is to use cogeneration. As the experience of using combined heat plants shows, fuel savings due to the combined production of electric and thermal energy is 13 % of the fuel consumption for electricity production. In the future, heat supply from NPPs should expand. This saves energy resources and reduces the burden on the environment. The use of steam condensation heat in the condenser of the NPP turbine as a low-potential source for a heat pump (HP) is considered. In this case, thermal pollution from the NPP is reduced. Currently, taxes for thermal pollution from NPPs are not charged, but, considering that this is one of their disadvantages and the great attention of humanity to the preservation of the environment, such taxes may soon be introduced. The work considers two options for the location of heat pumps to provide hot water supply to the city of Varash from the Rivne NPP: 1. Location of a powerful HP directly next to the NPP and transportation of hot water to the city. 2. Transportation of circulating water, heated in the condenser, to the city to provide HPs located near consumers. The comparison of these options was carried out on the basis of reduced costs, which took into account the cost of HPs, heat losses during the transportation of hot water and the cost of electricity for pumping. When taking into account the cost of HPs, the well-known formula for the dependence of specific equipment costs depending on capacity was used. As a result of the comparison, it was determined that the first option has the advantage. In the structure of reduced costs, the main contribution is made by the cost of heat pumps.
Study of temperature impact of discharges and balance of biogenic elements in the water of the Styr river in the impact zone of the Rivne NPP

Published: June 2024

Regardless of the type of cooling cycle, all nuclear power plants (NPPs) have a cooling water discharge with residual heat energy. Significant volumes of water are circulated in the cooling system of an NPP, which is withdrawn and discharged into a natural water body, thus transferring heat from the power plant to the water body. Changes in the content and balance of biogenic substances in surface waters under the influence of water discharges from an NPP can be considered as important indicators of water and environmental reactions to heat emissions from an NPP. The study aims to determine the dynamics of changes in the content of biogenic elements for the coexisting forms of nitrogen (N), phosphorus (P), and carbon (C) with the establishment of variability factors and correlations between their forms in the water of the Styr River, which is in the zone of water discharges influence from the Rivne Nuclear Power Plant (Rivne NPP). According to the results of the study, it was determined that the content of P (orthophosphate ions РО4 3-), C (biochemical oxygen demand for 5 days BOD5 and chemical oxygen demand COD) and N (ammonium nitrogen N-NH3 , nitrate ions NO3-) in the water of the Styr River in the zone of influence of water discharges from the Rivne NPP has seasonal dynamics. The correlation of the balance content of nutrients in the water of the Styr River before water intake and after discharge by the Rivne NPP was estimated. Regression statistical dependencies were established, which allow predicting the content of nutrient forms depending on the temperature by environmental and technical factors of temperature influence. In general, the research results indicate that there is no negative impact of the Rivne NPP water discharges on the balance of nutrients, and therefore no manifestation of the Styr River water-ecological reactions to the Rivne NPP heat release.

The influence of chelated complexes of trace elements (Mn, Zn, Cu, Co) with ethylenediaminedisuccinic acid on reducing the accumulation of radionuclides 137Cs and 90Sr in plants and animals was studied. Foliar feeding of fodder plants (lupins, rapeseed, oats, clover, etc.) in the conditions of the Ukrainian Polissia on turf-podzolic soils contaminated with radionuclides, with aqueous solutions of complexonates of trace elements reduces the accumulation of 137Сs in the vegetative mass and grain by 1.6–2.8 times and 90Sr in 1.4–1.6 times. Compared with sulfates of microelements, complexonates have a much higher radio-blocking efficiency. Treatment of plants with microelement complexes increased the yield of vegetative mass and grain by 17–36 % and 16–38 %, respectively. At the same time, there is an improvement in their nutritional quality in plants, the content of some metabolites (crude protein, crude fat, crude fiber, sugars) increases by 30–35 %. Addition of zinc-manganese and cobalt-copper complexonates to the diet of cows in amounts compensating for the natural lack of trace elements led to a decrease in the accumulation of 90Sr and 137Cs in milk and meat by almost 2 times. At the same time, when using complexonates, an increase in the milk productivity of cows by 15–25 % and the content of fat, proteins, weighty components in the milk of cows, which characterize the quality of milk, by 2–3 % were noted. At the same time, some immune indicators of the animals increased: leukocytes — by 11 %, basophils — by 44 %, rod and segmented leukocytes — by 30 and 37 %, respectively, monocytes — by 43 %, which indicates an improvement in the state of their immune system. Probably, the effect of the use of complexonates is due to greater permeability of microelements through cell membranes and the ability to directly integrate into the molecular structures of enzymatic systems, bypassing many transport chains.

In 2023, rice production reached 523.9 million tons, making it the fourth most produced crop globally. Accounting for 14% of global fertilizer use, the demand for rice continues to increase. However, the unbalanced application of NPK fertilizers poses significant environmental risks. An integrated nutrient management approach, combining organic and inorganic sources, offers a cost-effective solution to meet crop nutritional needs while enhancing soil health. Therefore, a field experiment was conducted in Experimental Farm of Annamalai University during kuruvai (June-September) 2023 to evaluate the effect of different levels of inorganic fertilizers with different sources of organic manures along with foliar zinc sulphate on the yield and yield components in lowland rice. The experiment was laid out in randomized block design with nine treatments. These treatments included different sources of organic manures viz., farm yard manure, vermicompost, press mud and poultry manure and foliar application of zinc sulphate. The results revealed that combining 75% nitrogen through urea and 25% nitrogen from vermicompost and 100 % P and K along with foliar application of zinc sulphate (0.5%) at 25 and 50 days after transplanting (DAT) significantly improved all nutrient uptake of nitrogen, phosphorous and potassium and also yield parameters viz., number of productive tillers m-2, number of filled grains/panicle, grain yield, straw yield and harvest index of rice.

This study seeks to gain a thorough understanding of the essential elements of inclusive education policy in Indonesia, as well as the obstacles faced in putting inclusive education into practice. This study used the Systematic Literature Review (SLR) method to collect and analyze data from 25 relevant articles on the topic under study and then selected 5 articles per topic. The findings show that there are several key components to ensuring equitable access to education for all children, including those with disabilities or special needs. However, the implementation of this policy is faced with various challenges, such as limited community involvement, lack of infrastructure and experts, inadequate teacher competence, limited teaching time, and policy misunderstandings and inconsistencies.

In the field, the effect of liquid mineral fertilizers and carbamide ammonium nitrate (LMF and CAN) in the agrocenoses of peas, chickpeas, coriander and flax on the biological activity of chernozems treated for a long time using null technology was studied. Among the biological parameters, the activity of enzymes involved in the carbon cycle (invertases, dehydrogenases), the intensity of soil respiration, the number of microorganisms, and the content of active carbon were evaluated. There is a difference in the effects of fertilizers on crops and different parameters of biological activity. The biological activity of the studied soils varied depending on the type of mineral fertilizer, as well as the cultivated crop.

A laboratory assessment of the effect of 4 fungicides containing active substance (a. s.) of different chemical classes on the growth of strains of 2 dominant species of Fusarium fungi, pathogens of fusarium dry rot of potatoes, was carried out. The drug containing benomyl most effectively suppressed the growth of F. sambucinum and F. solani strains by an average of 76 ± 4% compared with the control. The drug containing azoxystrobin turned out to be the least effective ‒ inhibition of strain growth averaged 35 ± 5%. The significant influence of the factors “species affiliation” and “region of origin” of the strain and their interaction on the sensitivity of strains of both Fusarium species to each of the 4 fungicides has been shown. The risk of developing resistance in F. sambucinum to a. s. of different classes was noted.

House flies Musca domestica L. (Diptera: Muscidae) serve as a common model organism for testing of insecticides and research of insecticidal resistance mechanisms in insects. One of important stages is to assess of detoxifying enzyme activities including carboxylesterase activities (CarE). In this study, we compared specific activities and kinetic parameters (Vmax and Km) of CarE in adults M. domestica of two laboratory strains (TY, UF) depending on the enzymatic substrate used. The specific CarE activities towards α- and β-naphthyl acetate (α-NA and β-NA) were similar in both males and females of the TY strain. In males of the UF strain, the value of the specific and the maximal velocity (Vmax) of β-NA hydrolysis was 1.90- and 1.57-fold respectively less than that of α-NA; this difference was not observed in females of the same strain. Some characteristics of CarE varied depending on sex of insects when p-nitrophenyl acetate was used as an enzymatic substrate. In particular, the specific activity was 1.62-fold less in males of the UF strain compared to this value in females. The activity and main kinetic parameters of CarE towards α-NA not differed statistically significant depending on sex and the strains. Based on the results obtained we suggest that α-naphthyl acetate is the preferred substrate to evaluate the CarE enzymatic activity in the model insect M. domestica of different strains.
