A reasonable reduction in the time of scheduled preventive maintenance of nuclear power units is a current direction for increasing the operational efficiency of the nuclear power industry in Ukraine. The main indicator of the operating efficiency of nuclear power plants (capacity factor) actually directly depends on the time of scheduled preventive maintenance of nuclear power units. One of the most effective approaches to reducing the time of scheduled preventive maintenance of power units is related to optimizing strategies of scheduled repair according to the technical condition of safety related systems. The introduction into operational practice of the concept of repair according to the technical condition of systems and equipment of nuclear power units determines the need to develop methods for substantiating strategies for optimizing the organization of scheduled repairs of the safety related systems of nuclear power plants, that take into account the impact of modernization of strategies for scheduled repairs of safety related systems on the safe operation conditions. A risk-informed method for optimizing safety related systems of nuclear power plants has been developed, which takes into account the impact of modernization of strategies of repairs according to technical condition on probabilistic safety factors. The developed risk-informed method defines permissible strategies of repairs according to technical condition of safety related systems in the three-parameter format “compliance of the determining parameters of the technical condition with the established criteria, Fussel-Veseli safety importance factor, Birnbaum safety importance factor”. Based on the developed method, a simplified example of optimizing strategies of repairs according to technical condition for the fittings of safety related systems of the 1st power unit of the South Ukrainian NPP is given, and the conditions of admissibility of modernization of the regulations of scheduled repairs are determined. The operating organization National Nuclear Energy Generating Company “Energoatom” can use the developed risk-informed method to reasonably reduce the time of scheduled preventive maintenance of power units and increase the capacity factor of Ukrainian nuclear power plants

Published: June 2024

This article provides an overview of global experience of radioactive waste (RAW) conditioning in terms of organizing and methodological approaches in using this RAW processing method, which were generalized in the documents of International Atomic Energy Agency (IAEA), in various analytical materials and scientific publications. Based on the analysis of available information materials, in different countries with developed nuclear fuel cycle, the conditioning is an integral part of the system of integrated RAW management, which includes the operations, during which they have be transferred to a form ensuring their stable chemical, thermal and radiation resistance for further transportation, storage and burial. The list of RAW produced during NPP operation and belonging to the conditioning, combines a variety of materials, which differ in their shape, concentration of nuclide activities and contamination type. The levels of specific activity of nuclides in the RAW vary from very low levels to extremely high levels inherent to spent nuclear fuel, which requires providing conditions of their subcriticality underway technological operations. It is stated that the most worked out method of RAW conditioning within the industrial scale is immobilization, which is aimed at wastes transformation into a solid form using the processes of their solidification after inclusion in any matrix, or inclusion in sealed casings. Radioactive components can be immobilized into a matrix material based on bitumen, polymers, cement, glass, ceramics, and glass ceramics by using two main processes: binding them into a material at atomic level — chemical inclusion or physical environment and isolation — encapsulation.

The methodology of radioecological zoning of the territory of possible radioactive contamination was applied to analyze the consequences of a hypothetical radiation accident at the Khmelnytskyi NPP (KhNPP). With the help of the European decision support system in the event of a radiation accident RODOS, as well as a set of models of aerial and root contamination of vegetation, developed at the Institute for Safety Problems of Nuclear Power Plants of the National Academy of Sciences of Ukraine (ISP NPP NASU), modeling of the transport of radioactive emissions, their deposition on the underlying surface and radioactive contamination of agricultural products within the 100-kilometer zone of the KhNPP influence. Using the obtained calculation results as an example, it is shown that preventive radioecological zoning of the territory of influence of a nuclear power plant, with following highlighting the most radioecologically critical areas, ensures the most optimal interaction between a computer system for forecasting the radiation situation and a radioecological monitoring network. This makes it possible, in the initial period of the accident, to reduce the uncertainty interval of the resulting estimates, to create an optimized scheme for radioecological monitoring of the territory of the agricultural production, and to allocate areas for the production of products with exceeded standards of radionuclides concentration.

Importance of Providing Soils with Mobile Potassium in Increasing the Yield and Efficiency of Nitrogen Fertilizers
Authors: Shafrаn S. A.
Published: June 2024

The results of a study devoted to the study of the effect of the content of mobile potassium in various soils on the yield of major crops and the effectiveness of the use of nitrogen fertilizers for them are presented. According to the data obtained, the availability of mobile potassium in soils plays a very significant role in increasing the yield of cereals, potatoes and flax. To the greatest extent, this affected sod-podzolic soils, on which the yield increase was higher due to an increase in their potash level and a higher return on nitrogen fertilizers. Among the studied crops, winter wheat stood out, which reacts better than others not only to an increase in the K2O content in the soil, but also in general to their agrochemical cultivation. On sod-podzolic and gray forest soils, its yield increased 3 times, on leached chernozems – 2.5 times, whereas on the same soils, the yield of spring wheat increased 1.2–1.3 times, potatoes – 1.5 times and flax, depending on the predecessor – 1.7–1.9 times. The dependence of the efficiency of nitrogen fertilizers on the content of mobile potassium in soils has been established.

In 2020–2021, in the central zone of the Krasnodar Territory, a study was conducted on the effectiveness of a biostimulator based on triterpene acids Grow–B on tobacco of the promising variety Sheptalsky 63. According to the results of the use of a growth-stimulating agent with a fungicidal effect in laboratory conditions, it was found that pre-sowing soaking of tobacco seeds at a concentration of 0.05% for 6 hours increased the weight of tobacco seedlings by 43%. Sowing of treated tobacco seeds in a greenhouse together with additional double treatment of seedlings in the development phases “ears” and “fit for planting” with a solution of the biostimulator Grow–B in a concentration of 0.05% increased the number of leaves on plants by 18, the length of seedlings from the root neck to the point of growth – by 37, to the end of the elongated leaves – by 24, the diameter of the stem is by 30, the crude mass of the aboveground part and the root system is by 96 and 95%, respectively. The yield of standard seedlings per unit of greenhouse area increased by 29%. The survival rate of plants in the field reached 98, their height increased by 12 by the end of the harvesting period, the area of tobacco leaves of the middle tier – by 28, yield – by 37% compared with the control. Pre-sowing soaking of seeds and seedling treatment with the Grow–B biostimulator increased the amount of nicotine in tobacco raw materials by 34, carbohydrates by 68, and reduced the amount of proteins by 13%. The number of Schmuck (carbohydrate-protein ratio characterizing the quality of raw materials) increased by 89% against the background of a biostimulator.

Published: June 2024

Angeli’s salt is regarded as a nitroxyl donor, so it can counteract hemolysis-driven adverse effects such as the vasoconstrictive effects of free hemoglobin in blood plasma. However, the molecular mechanisms of interaction of nitroxyl with various heme proteins are not fully understood. Oxoferryl forms of hemoproteins emerged under oxidative stress are known to be strong pro-oxidants. This study has been carried out to investigate reductive nitrosylation of metand oxoferryl forms of hemoglobin and myoglobin upon interaction with nitroxyl. Experiments were performed in vitro using electron paramagnetic resonance spectroscopy for detection of nitrosyl forms. The results obtained indicate the antioxidant effect of Angeli’s salt in model systems of hemoglobin or myoglobin oxidation with hydrogen peroxide. Moreover, the addition of hydrogen peroxide to methemoglobin and metmyoglobin led to the appearance of an EPR signal of free radicals with g = 2.005, associated with the protein part of hemoproteins. Thus, nitroxyl acts both as a reducing agent and a nitrosylating agent, thereby preventing the formation of oxoferryl forms of hemoproteides. The therapeutic properties of Angeli’s salt may be largely related to the antioxidant effect it has on blood components.

The present study has been carried out to investigate changes in the structural characteristics of mitochondrial membranes isolated from epicotyls of pea seedlings of variety Nemchinovskiy 100 under the influence of different concentrations of NaHS. It was shown that treatment of pea seeds with NaHS at doses of 2∙10–4 and 5∙10–6 M resulted in the shift of thermally-induced structural transitions toward the region of lower temperatures and an increase in the microviscosity of both lipid and preprotein regions of mitochondrial membrane due to a decrease in the volume of their crystallization matrix. The presence of exogenous NaHS or endogenous hydrogen sulfide can enhance the activity of antioxidant defense enzymes and lead to accumulation of osmolytes. As a result, the microviscosity of the lipid bilayer could increase. To test this hypothesis, the effect of resveratrol, an antioxidant agent, on microviscosity of the lipid bilayer of epicotyl mitochondria of pea seedlings was investigated using normal pea seeds treated with resveratrol with or without pre-treatment with NaHS. Additionally, bioenergetic characteristics of mitochondria were studied. The results obtained confirmed that hydrogen sulfide has an effect on the structural characteristics of mitochondrial membranes through the activation of antioxidant enzymes and accumulation of osmolytes.

Cryptoization and Shadow Currency: Legal Overview of the Importance of Digital Rupiah in Indonesia
Authors: Sulistiyono Adi , Kharisma Dona Budi
Published: June 2024

Cryptoization in Indonesia can be seen in the number of investors and crypto asset transactions. As of January 2024, the total number of crypto asset investors reached 18.83 million investors. Meanwhile, the total accumulated value of crypto asset transactions throughout 2024 was recorded at IDR 48.82 trillion. Various types and developments in crypto assets trigger shadow currency risks. Shadow currency is a currency function that can be replaced by another form. In this regard, research is needed regarding the relationship between crypto assets as shadow currency in financial stability and the importance of regulating digital rupiah in Indonesia. The approach used is the statute approach. This research will examine various laws and regulations relating to crypto assets, fintech, financial systems and currencies. The research results show that the crypto asset transaction process occurs outside the official monetary system and can develop into a digital currency area outside certain jurisdictions. The materialization of this risk can threaten a country's monetary sovereignty, thus triggering the risk of shadow currency. Therefore, it is recommended that the Digital Rupiah be a Central Bank Digital Currency (CDBC) which is officially implemented in Indonesia. However, there needs to be regulatory and policy support needed so that CBDC can be implemented in Indonesia, one of which is through a revision of the Indonesian Act on Currency.

Published: June 2024

This study aims to determine the role of parents in Agam Regency in preventing bullying against children in elementary schools. Juridically, the state regulates that parents are obliged to maintain, educate, and instill good ethical values to children. On that basis, each parent is obliged to carry out their respective roles to develop children's potential so that children avoid bullying in elementary schools. This research departs from field research with descriptive research type. The subjects of this study were parents of elementary school students in Agam Regency as many as 79 respondents consisting of 60 women (mothers) and 19 men (fathers). The research instrument is a valid questionnaire on the role of parents in responding to bullying. The data obtained were analyzed using the percentage technique. The results of this study reveal that fathers and mothers have played a good role in encouraging the development of children's potential positively. Likewise with the item of equipping children with self-concept strengthening. Meanwhile, the item about parents' actions to provide time with children has not produced good percentage criteria. The wrong perspective of parents in carrying out their roles has implications for the non-optimal guidance, education, and guidance to children in terms of preventing bullying in elementary schools.

Preparing Pre-service Teachers to Teach Reading Strategies within a Mixed Reality Simulation Environment
Authors: Nel Carisma
Published: June 2024

As a language teacher, teacher educator and researcher, to me the name Rebecca Oxford has always been synonymous with language learning strategies across the world and specifically the theme of its teachability. Rebecca has always stated that the language teacher’s role includes strategy instruction even if it achieves only partial success. Research has focused almost exclusively on how reading comprehension strategies, the focus of this study, can be taught to learners, but the preparedness of pre-service teachers to teach reading strategies has seldom been the focus within initial teacher education programs. The purpose of this study was to determine participants’ perceptions of teaching within a mixed reality simulation environment with a specific focus on the explicit instruction of reading comprehension strategies. A case study approach was utilized, and ten second-year pre-service teachers enrolled for the Bachelor of Education (B.Ed) degree as well as one mentor teacher and one teacher educator were purposefully selected to participate in the study. The results indicated that the themes corresponded with the activities during the different stages of a mixed reality simulation action review cycle and included show and tell, collaborative brainstorming, deconstruction of the core teaching practice, anxiety and disbelief, pause and redo, coaching and feedback and focused reflection.
Language Learning Strategies, Proficiency And Gender: The Case of Palestinian University Students
Authors: Abuzaid Muhannad , Griffiths Carol
Published: June 2024

This case study, conducted at a Palestinian university, explored the language learning strategies employed by learners of English as a foreign language and the relationship with proficiency. Furthermore, since gender is often considered a major variable in learning success in some areas of the world, the study wished to explore the role of gender in strategy use and level of proficiency in the Palestinian context. The study included 109 (41 male, 68 female) students studying in English preparatory courses prior to entering the university. The data were gathered through an original 60-item language learning strategy questionnaire, modelled to some extent on the Strategy İnventory for Language Learning or SILL (Oxford, 1990) and constructed from material contributed by the students themselves. The results indicated that students reported medium to frequent strategy use, which was not significantly related to proficiency level, and there were only three significant gender differences according to strategy use, in favor of the females. This suggests that gender is not a salient influence in these students' strategy use or levels of proficiency. This article concludes by suggesting implications both for the immediate context of the study and also for environments beyond the location of the current study.

The purpose of this corpus-based study is a bottom-up investigation of strategic devices used by heritage language speakers (HLSs) during narration and conversation. It offers a critical review of compensation/communication strategy definitions and classifications, and presents the results of an investigation into strategies employed by an under-researched target group, that of HLSs. The study is not based on any a priori classification scheme; rather it is data-driven. Conversation analysis used to analyze the data revealed, among other, that the 70 Greek HLSs, a heterogeneous group with diverse linguistic, cultural, and affective characteristics from the U.S. (Chicago) and Russia (Moscow and St. Petersburg), employed 14 strategic resources. All three communities used the same strategies, except for loanblends, which were used only by HLSs from Chicago. The latter also exhibited a more frequent use of strategies overall. We conclude that, in spite of their linguistic challenges, the HLSs were capable of achieving their interactional goals. HLSs generally have opportunities to use HL in the community/family, which enriches their strategic repertoires and facilitates language production. However, not all HL environments are language conductive and, as a result, HL learners’ curricula should provide explicit strategy instruction in order to increase their speaking skill.

BACKGROUND: Fibromyalgia is a debilitating condition marked by persistent pain and reduced functionality. Various therapeutic methods have been suggested to alleviate symptoms in individuals with fibromyalgia, yet the impact of diverse rehabilitation strategies remains unclear. OBJECTIVE: This systematic review and meta-analysis aimed at assessing the efficacy of rehabilitation interventions in improving functioning in fibromyalgia patients. METHODS: We conducted a comprehensive literature search of multiple international databases (PubMed, Scopus, and Web of Science) from their inception until November 22nd, 2023. We identified 23 randomized controlled trials (RCTs) assessing multiple rehabilitation strategies. The primary outcome was the Fibromyalgia Impact Questionnaire (FIQ). Study quality was assessed using the Cochrane Risk-of-Bias Tool for Randomized Trials (RoB 2). The study protocol was registered in PROSPERO (CRD42020197666). RESULTS: Our meta-analysis rehabilitation interventions significantly reduce FIQ scores (MD =-11.74, 95% CI: -16.88 to -6.59, p< 0.0001). Notably, the subgroup analysis showed that different rehabilitation modalities seem to induce different therapeutic responses. CONCLUSIONS: Rehabilitation strategies hold promise in addressing the functional impairments and improving the overall well-being of individuals with fibromyalgia. The study underscores the need for further research to determine the optimal rehabilitation approach and its potential impact on the multilevel disability characterizing patients with fibromyalgia.
Sustained acoustic medicine treatment of discogenic chronic low back pain: A randomized, multisite, double-blind, placebo-controlled trial
Authors: Ortiz Ralph , Motyka Thomas , Petterson Stephanie , Krystofiak Jason
Published: June 2024

BACKGROUND: Sustained acoustic medicine (SAM) is a noninvasive long-term treatment that provides essential mechanical and thermal stimulus to accelerate soft tissue healing, alleviate pain, and improve physical activity. SAM increases localized deep tissue temperature, blood flow, cellular proliferation, migration, and nutrition exchange, resulting in reduced inflammation and an increased rate of tissue regeneration. OBJECTIVE: To assess the efficacy of SAM treatment of discogenic back pain in the lower spinal column to reduce pain, improve quality of life, and lower pharmacotherapy use. METHODS: Sixty-five subjects with chronic low back pain were randomly assigned to SAM (N= 33) or placebo (N= 32) groups. Subjects self-applied SAM device bilaterality on the lower lumbar region for 4 hours daily for 8 weeks and completed daily pain diaries before, during, and after treatment. Subjects recorded pain reduction using a numeric rating scale (NRS), medication use, and physical activity using the Global Rating of Change (GROC) and Oswestry Disability Index (ODI). RESULTS: SAM treatment significantly reduced chronic lower back pain from baseline relative to placebo treatment (p< 0.0001). SAM treated subjects reported significantly lower back pain at 4 weeks, with the highest pain reduction (-2.58 points NRS, p< 0.0001) reported at 8 weeks. Similar trends were observed in improved physical activity (3.48 GROC, p< 0.0001, 69–88% ODI, p< 0.0001) and 22.5% (15.2 morphine milligram equivalent) reduction in the use of opioid medication from baseline to 8 weeks. CONCLUSION: Daily, home-use SAM treatment significantly improves the clinical symptoms of chronic lower back pain, improves physical mobility, and reduces daily medication use. SAM treatment is well-tolerated by patients and may be considered a safe, non-invasive treatment option for chronic discogenic, lower back pain.

Bangladesh is one of the most vulnerable countries in the world to climate change. However, data relevant to ocean warming (OW) and ocean acidification (OA) are not readily available. This is the first study to review the available data relating to OW and OA covering the three parts (eastern, central and western parts) of the coastal marine waters (CMWs) of the Bay of Bengal (BoB), Bangladesh. The review compared the data collected from the three parts of the BoB, Bangladesh with the data and information of previous research carried out within the Indian subcontinent of the BoB (2000-2023). The present research provides an overview of water quality data relevant to OW and OA and the correlation among different water quality parameters. Our research found that the sea surface temperature is increasing and pH levels are decreasing in the BoB, Bangladesh. The current pH in BoB, Bangladesh is still alkaline, with an overall mean pH of 7.58 compared with the global ocean pH of 8.1. DO (overall mean: 6.09 mg/L), Ωarg (overall mean: 2.27) and Ωcal (overall mean: 3.59) levels were found to be within the safe thresholds for marine biota (fish, crustaceans, mussels, oysters, corals and echinoderms). Conversely, nitrate levels (mean: 2.29 mg/L) were found to be high, the concentration of which may enhance nitrogen pollution, algal blooms and hypoxia in the BoB, Bangladesh. The implications of OW and OA on Bangladesh’s fisheries and seafood have been briefly discussed.
Discovery of Besdolus bicolor (Navás, 1909) in France, and complements to the description of its vibrational duet (Plecoptera, Perlodidae)

Besdolus bicolor (Navás, 1909) is identified for the first time in France. Surveys resulted in the collection of individuals from historically known or more recently stations, as well as the examination of specimens stored in collections (previously identified as “Besdolus ventralis”). The species is present in the southern third of France. Its distribution is compared with that of other Besdolus, thus allowing us to observe an overlap or proximity of distribution areas for certain species. Recordings of sexual vibrational signals from France confirmed the species identification and allowed for the description of the female’s answer and the duetting pattern.
