HUBUNGAN KUALITAS HIDUP PASIEN HEMOFILIA DEWASA DENGAN STATUS GIZI, AKTIVITAS FISIK DAN TINGKAT KEPARAHAN HEMOFILIA DI KOTA MANADO
Authors: Kaunang Timothy Abiel Salomo , Mongan Arthur Elia , Rampengan Novie Homenta
Published: January 2025

Hemofilia yakni gangguan bawaan yang dapat menyebabkan darah sulit berhenti dengan normal, sehingga bisa menimbulkan perdarahan spontan apalagi setelah cedera atau operasi. Gejala perdarahan yang biasanya pada hemofilia meliputi perdarahan otot/jaringan lunak (hematoma) serta perdarahan sendi (hemarthrosis). Aktivitas fisik diperlukan bagi pasien hemofilia untuk mempertahankan status gizi baik. Namun, bagi pasien hemofilia harus membatasi jenis olahraga yang dilakukan karena gerakan atau kegiatan fisik yang berlebihan dapat menyebabkan perdarahan. Tujuan penelitian ini ialah menilai hubungan kualitas hidup pasien hemofilia dewasa dengan status gizi, aktivitas fisik dan tingkat keparahan hemofilia di Kota Manado. Penelitian ini mengaplikasikan desain observasional analitik dengan pendekatan potong lintang (cross-sectional). Populasi terdiri dari 30 pasien hemofilia dewasa di komunitas HMHI cabang manado, yang seluruhnya dijadikan sampel (total sampling). Variabel terikat kualitas hidup, variabel bebas status gizi, aktivitas fisik dan tingkat keparahan hemofilia. Instrumen penelitian meliputi lembar karakteristik responden, kuesioner WHOQOL-BREF dan IPAQ serta alat pengukur IMT. Hasil penelitian menggunakan uji korelasi Spearman mengungkapkan bahwa tidak terdapat hubungan yang bermakna antara status gizi dan kualitas hidup pada pasien hemofilia dewasa (r = -0.124, p = 0.513). Namun, ditemukan hubungan yang signifikan antara kualitas hidup dengan aktivitas fisik (r = 0.523, p = 0.003) serta dengan tingkat keparahan hemofilia (r = -0.472, p = 0.008). Kesimpulan dari penelitian ini ialah kualitas hidup pasien hemofilia menujukan adanya hubungan dengan aktivitas fisik dan tingkat keparahan hemofilia, sementara status gizi tidak menunjukkan hubungan signifikan.

Authors: Chin Chur
Published: January 2025

Sudden accerelation of cars and plane crash can be caused by the violation of a proper time dilatation of General Relativity by the existance of pair production under electromagnetic energy provision in the cars or the planes. Gravity wave is produced from evaporating primordial black holes (BH) in the living object. These black holes emit gravitons which are registered as gravity waves.
The Awakening Society: Conscious Anarchy as a New Beginning
Authors: Marozau Raman
Published: January 2025

This manuscript introduces Conscious Anarchy, a philosophy designed to align human society with principles of sustainability, equity, and cooperation. It addresses the flaws of current systems – control, inequality, and unsustainable hierarchies – by proposing a transformative framework grounded in decentralized governance, ethical resource distribution, and the responsible use of technology.Conscious Anarchy fosters a gradual awakening to humanity’s interconnectedness. It emphasizes practical steps such as integrating empathy into education, testing decentralized governance models, and leveraging technology for transparent resource management.While full transformation may take generations, immediate action is essential. By embracing balance and cooperation, humanity can avert systemic collapse and create a sustainable, equitable future. Conscious Anarchy invites individuals, communities, and institutions to contribute to this shared vision of lasting harmony and collective growth.

Convergent margins are gateways to Earth’s interior where volatile species are cycled between the planet's surface and interior. At these locations, carbon is recycled from deep reservoirs in two main forms: oxidized carbon, such as carbon dioxide, and reduced carbon, such as methane. While the former is quantitatively more important and its volcanic fluxes have been better constrained, the latter represents the most reduced form of carbon on Earth and greatly contributes to greenhouse effects and climate stability. Understanding the geological and biological processes underpinning the origin and fate of methane in convergent margins is thus pivotal to constraining carbon cycling and redox balance in convergent margins. Here, we present coupled geochemical and microbiological data from 47 geothermal deeply-sourced seeps spanning the Costa Rica and Panama convergent margin. By analyzing the presence and diversity of methane-cycling microorganisms and using clumped isotope data, we observed that biotic and abiotic processes are both involved in driving the quantity and isotopic signature of methane cycled to the surface, providing an unprecedented snapshot of the geobiological processes controlling methane cycling in convergent margins.
Learning to be confident: How agents learn confidence based on prediction errors
Authors: Le Denmat Pierre , Desender Kobe , Verguts Tom
Published: January 2025

Decision confidence should normatively reflect the posterior probability of making a correct choice, conditional on relevant information. However, how individuals learn to calibrate their sense of confidence to that probability remains unknown. The standard approach to estimate any quantity is to use trial-by trial samples of that quantity to train a function approximator (such as a neural network) based on the prediction errors (quantity minus prediction of the quantity). We tested whether humans learn about confidence using this principle in a perceptual decision-making experiment where participants repeatedly alternated between two manipulated feedback regimes (negative vs positive) every few blocks of trials. As anticipated, confidence ratings tracked feedback, with confidence gradually increasing when participants received overall positive feedback (and thus positive prediction errors), and decreasing when receiving negative feedback (and thus negative prediction errors). These feedback-induced dynamic changes were specific to confidence, as objective performance was unaffected by the manipulation. We propose a single-layer neural network model for confidence which updates the computation of confidence based on trial-level prediction errors, and demonstrate that it provides a good fit to the behavioral data. Taken together, these results show that the computation of confidence is dynamic: humans constantly update how they compute confidence based on prediction errors (feedback minus prediction), in a statistically efficient manner.
Gratification Control in Adult Health Risk Behaviors: Development of the HeRBs GCI
Authors: Verma Adarsh K. , Chivukula Usha , Thasleema Aysha
Published: January 2025

Effective impulse control over gratifying stimuli is a crucial skill with significant implications for decision-making across various life domains. While research has traditionally centered on the concept of delayed gratification (DG)- primarily studied in children - its application to adult behavior reveals distinct complexities. This study shifts attention to gratification control (GC), a construct that focuses on how adults navigate competing desires in the context of both immediate and long-term health risks. The Health Risk Behaviors' Gratification Control Inventory (HeRBs GCI), designed to measure GC, comprises 12 items across four domains: alcohol consumption, smoking, drug abuse, and risky sexual practices. Validated with a sample of 442 emerging adults, the HeRBs GCI offers insights into impulse control concerning health risk behaviors. This inventory provides a tool for research and practical interventions aimed at enhancing decision-making and managing health-related risks.

Authors: Choma Joshua , Griffiths Alys , Henley William , Mueller Christoph , Williams Nefyn , Ballard Clive , Hopkins Rhian , Young Katherine , Dennis John , Creese Byron
Published: January 2025

Background: Agitation and aggression occur in up to half of people living with dementia over the course of the disease. While non-pharmacological interventions are first line treatment strategies, in severe cases associated with a risk of harm, antipsychotics may be indicated. A major adverse effect of antipsychotics in dementia is an increased risk of stroke and the atypical antipsychotic risperidone’s mechanism of action has been linked to cardiovascular disease (CVD) biological pathways. Aims:To evaluate the risk of stroke associated with risperidone use across different patient subgroups defined by stroke and CVD history.Method:Anonymised primary care data from the UK-based Clinical Practice Research Datalink (CPRD) was used to identify individuals diagnosed with dementia after the age of 65 between 2004 and 2023. Risk of stroke over one year was compared between individuals initiating risperidone and propensity score-matched controls.Results: In the overall cohort (28,403 Risperidone Users and 136,324 Matched Controls), patients treated with risperidone had an increased risk of stroke (adjusted hazard ratio (HR): 1.28; 95% confidence interval (CI): 1.20-1.37). In the Risperidone User group, the incidence rate (IR) of stoke was substantially higher in those with a prior history of stroke (IR: 222 per 1000 person-years (PY)) and CVD (IR: 94.1 per 1000 PY) than in the overall cohort (IR: 53.3 per 1000 PY). Relative risks related to risperidone were similar across all CVD and stroke subgroup comparisons (HRs between 1.23 and 1.44). Conclusions:People with dementia with a prior history of CVD are at a significant increased risk of stroke and risperidone further exacerbates this risk. Moreover, risperidone also increases risk of stroke in patients without a prior history of CVD. This quantification of stroke risk across subgroups with and without history of CVD may help with communication risk and aid more judicious prescribing.

Published: January 2025

Building on the long and successful tradition of incorporating games (e.g., chess or Mastermind) into the psychological assessment of cognitive ability, this registered report focuses on Wordle—one of the most popular online word games. We will examine (1) the psychometric properties of the game (e.g., dimensionality, reliability), (2) the nomological network of Wordle proficiency including vocabulary, verbal fluency, and reasoning at the latent level, (3) correlations with socio-demographic (age, education), reading habits, game experience, and strategy efficiency, and (4) the game’s potential for rational test construction through an analysis of the linguistic determinants of Wordle item difficulty.
Formal-Informal Paradox of Indigenous Entrepreneurship in Bangladesh
Authors: Juha Sharmin Jahan , Mizan Arefin
Published: January 2025

Recent research in the emerging field of ‘Indigenous Entrepreneurship’ is revealing that there are various conditions and values present when it comes to Indigenous businesses and enterprises, that fundamentally challenges the common assumptions about entrepreneurship. This study aims to address the challenges that ethnic minorities in Bangladesh, otherwise known as Indigenous people (IP), face in their entrepreneurial ventures while remaining in the informal sector, and recommend policy initiatives to counteract those challenges. We hypothesize that the Indigenous economy’s entrepreneurial landscape mainly comprises informal entrepreneurship. Which inevitably creates barriers to accessing financial institutions, incentives and services provided by the Government of Bangladesh (GOB) and other formal institutions, necessary for Small and Medium Enterprises (SME) to scale up and maximize market development. For this study, we used 67 case studies of IP-led businesses and startups in Bangladesh, in conjunction with the Future of Business Survey Data from Facebook. We use Fuzzy-set Qualitative Comparative Analysis (Fs/QCA), a novel analytical method to identify complex interacting causal factors from a large body of case studies. We hope to provide a sound basis for policy interventions based on practical and perceived needs of IPs, which are required to make entrepreneurship in Bangladesh more inclusive and ensure that IPs have a level playing field in the formal economy of Bangladesh.
Bridging the Divide: Temporal Inequality as a Neglected Dimension in Sociological Research
Authors: Shi Yuan
Published: January 2025

Time is an essential but overlooked dimension of inequality in modern societies.While money can be earned and saved, time remains finite, shaped by labor markets,caregiving duties, and institutional frameworks. Despite its importance, mainstreamsociological research on inequality and resources have predominantly focused onmaterial and economic factors and overlooks temporal factors. This manuscriptcenters on the concept of temporal inequality—the unequal distribution of and controlover time—to demonstrate that focusing solely on material resources overlookscritical constraints on daily life and offers ground work for further research. Buildingon sociological theories of capital, intersectionality, and economic stratification, thisarticle argues that time poverty intersects with race, class, and gender inequalities,deepening existing social divides. By foregrounding time, this article aims to advancea more holistic understanding of social stratification.

Published: January 2025

Over the past 50 years, large transnational "keystone" corporations have concentrated power and gained significant influence over the world's resource reserves, production and trade. The Kunming-Montreal Global Biodiversity Framework emphasizes the crucial role of businesses in setting and disclosing targets to mitigate their impact on nature. In this study, we identified 180 keystone corporations from highly concentrated sectors with significant environmental impacts and assessed their biodiversity commitments. Our findings reveal that while 79% of firms have made some form of biodiversity pledge, only 13% have reported sufficiently detailed, transparent and specific commitments (“robust commitments”) to allow others to assess if the targets have been met – a key prerequisite of accountability. We discuss future directions and underscore the urgent need for companies, governments, and civil society – including the research community – to work collaboratively to develop, implement, and monitor credible corporate strategies that drive meaningful action for nature.
The Irizarry Hair Texture Scale
Authors: Irizarry Yasmiyn
Published: January 2025

The Irizarry Hair Texture Scale (IHT) is a novel framework that captures both the physical and socio-cultural dimensions of hair texture, challenging traditional classification systems that perpetuate racial hierarchies. Developed through interdisciplinary research and informed by critiques of racialized beauty standards, the IHT spans a spectrum from straight to coily textures, incorporating factors such as curl pattern, density, and style. This scale provides a scientifically grounded approach to studying hair as a marker of identity and systemic inequities.

Published: January 2025

This study was conducted in Kaski district among 100 commercial vegetable farmers using a pretested interview schedule to access the pesticides used, respondent's knowledge, health hazards experienced and safety measures on use of pesticides. MS Excel and SPSS were used to analyze the data. Insecticides, fungicides and neem-based herbal pesticides were majorly used in vegetables while agro-vets were the major source of information to the farmers. Majority of the farmers were aware about the trade names, color label, banned pesticides, waiting period and effect of misuse of pesticides while only a minority of them were aware about the working mode of action of pesticides. About 40% farmers reported health issues on use of pesticides; major symptoms experienced were dizziness and skin irritation. Majority of farmers only used mask and gloves during application of pesticides. It was found that a majority 52% farmers were categorically spending less on pesticides while pesticide use was found to be a determining factor of income in vegetable farms.

Political Consciousness Among Dalit and Non-Dalit
Authors: Adhikari Ram Chandra
Published: January 2025

This study examines caste-based discrimination against Dalits in Bharatpur 12, Chitwan district, Nepal, focusing on their social, economic, and political conditions. Data were collected through a survey of Dalit and non-Dalit households using structured questionnaires. The results showed that most household heads were male. Unemployment was higher among Dalits (54.20%) than non-Dalits (45.80%), and more non-Dalits (51.60%) worked in agriculture compared to Dalits (48.60%). Average land ownership was small at 0.14 hectares, and most families were nuclear. Hinduism was the main religion (71.25%), followed by Christianity (16.25%) and Buddhism (12.25%).
Mobile phones were the most commonly used communication tool, followed by television (88.75%) and social media (70.00%). Participation in political campaigns was low, especially among Dalits. About 90% of respondents said caste did not influence their voting decisions. However, 15% admitted voting for money. Awareness of political agendas was high (70%), and development issues influenced 53.75% of voters. The most important criteria for voting were commitment to development (63.75%), followed by the candidate’s education (25%) and personal relationships (11.25%). Dalits were less consistent in their political preferences, often changing parties based on the performance of candidates and their community’s needs.
The findings highlight the ongoing challenges of unemployment, limited resources, and political disengagement among Dalits. Addressing these issues requires focused efforts to improve economic opportunities, increase political participation, and reduce caste-based discrimination

Light in the Dark: Thick and Thin Development during the Rana Period in Nepal
Authors: Nepal Ratna Mani
Published: January 2025

In Nepalese political history, the Rana period (1846-1950) is characterized as a ''dark age'' representing the state of skimpy social, economic, and political changes. This article examines the period through modern development perspectives and explores if the politically dark period endured developmental lights. This objective is based on the assumption that development is a necessary as well as sufficient condition of any society in any historical context and, therefore, embedded in its social, economic, and political processes. This article applies a historical and analytical-interpretative approach to examine archival records obtained from various sources, including the TU-Central Library, Gorkhapatra Sansthan, CNAS-TU, and Department of Archeology, Nepal Government, and online databases. Collation of the documentary evidence reveals that the Rana period commenced and endured glimpses of development in perspectives and patterns. The era instituted a foundation of some significant socio-economic development in Nepal. Two concepts can better represent the trends in the period, namely, thick development and thin development. The thick development appears in reform initiatives undertaken by the Rana Regime while grassroots mobilizations represent thin development. This article concludes that in a combination of thick and thin developments, several flashlights qualified the Rana period, the so-called “dark age.” The finding of this article also qualifies the term development. It implies that development transcends history, meaning that development is a historical concept. Any attempt to bracket development in timelines is questionable. It also reveals that development is primarily local, embedded in the specific ecological, social, economic and political contexts of a society.

Landscapes in Transition: A Study of Agricultural Land Use Change in Inner Terai of Nepal
Authors: Timilsina R.H. , Ojha G.P. , Nepali P.B. , Tiwari U.
Published: January 2025

Agricultural land use has raised concerns about the sustainability of locally led food systems. With urbanization in Chitwan district, cropland has been haphazardly used for different purposes. However, spatial-temporal cropland use changes in municipalities have not been explored. This research assesses the land use and land cover changes in six municipalities of Chitwan over two decades (2001 to 2021). Landsat images and the Google Earth platform were used to classify the land use. The study mainly focuses on the conversion of cropland to seven other land uses categories, and vice versa. The findings reveal a significant increase in built-up areas, particularly between 2011 and 2021, at the expense of agricultural land. The key drivers of these changes include the political system change notably the introduction of federalism and local governance in 2015, which has led to rapid migration, infrastructure development, and the expansion of urban centers. These land use changes pose challenges for sustainable agricultural land management, with cropland being replaced by built-up. Nevertheless, advancements in agricultural technologies have also converted other land use categories to cropland. This study emphasizes the urgent need for locally adaptable land use policies in line with national agricultural development strategies. The findings assist policymakers in developing sustainable land use strategies that maintain agricultural productivity while accommodating urban expansion. Timely intervention from the policy level is critical to protecting agricultural land and promoting a resilient, self-sufficient agricultural system in the face of ongoing urbanization and demographic changes.

Reporting Lines of Inquiry: Documenting Evaluations and Making Values Explicit
Authors: Teasdale Rebecca M. , Moore Ceily L. , Strasser Mikayla
Published: January 2025

The Program Evaluation Standards call for “rigorous documentation of evaluations” and emphasize evaluators’ responsibility to make explicit the key values that shape evaluations. Clear, complete, values-attentive evaluation reporting is necessary so constituents can understand, learn from, critique, improve, and take action based on evaluations. Yet, scholars have documented gaps in reporting that can limit understanding of evaluations. In this practice note, we provide guidance for reporting a central, value-laden component of evaluations: lines of inquiry. An evaluative line of inquiry is a linked set of an evaluation question, associated criteria or constructs/variables, data collection or analysis method(s), findings, and evaluative conclusion(s) that addresses a specific dimension of quality. We draw on a recent empirical analysis to outline the elements evaluators should include when reporting lines of inquiry and share exemplars that illustrate ways to communicate the links among these elements. We offer this guidance to assist evaluators in documenting their evaluations and making key values explicit to ensure meaningful understanding of evaluations.
ФОРМУВАННЯ ЕКОЛОГІЧНОЇ КОМПЕТЕНТНОСТІ У ФАХІВЦІВ ПРИРОДНИЧИХ НАУК ЗАСОБАМИ ЦИФРОВИХ ТЕХНОЛОГІЙ
Authors: Бондаренко Л. І.
Published: January 2025

Стаття присвячена питанню обґрунтування необхідності формування екологічної компетентності у фахівців природничих наук з умовах повномасштабної війни в Україні засобами цифрових технологій. Екологічна компетентність представлено як інструмент, що сприятиме прийняттю екологічно обґрунтованих рішень, щодо екоцидів зараз та швидшому й ефективнішому відновленню територій, що зазнали нищівних змін внаслідок військових дій.
Поточна ситуація в Україні потребує перегляду освітньої моделі й розширення екологічного вектору навчання. Внаслідок повномасштабної війни відбулась переоцінка світоглядних позицій. Вона починалась з виявлення і усвідомлення всіма громадянами значення не лише володіння певною базою теоретичних знань, а вміння застосовувати їх в своїй практичній діяльності, особливо в критичних ситуаціях, що потребують рішучих дій.
Це стосується й екологічної складової життя суспільства. Станом на січень 2024 року було зафіксовано близько 3,6 тис. злочинів проти довкілля, знищено Каховську ГЕС, заміновано великі за площею території тощо, а отже необхідність фахівців різних галузей достатньо компетентних в питаннях усунення екологічних наслідків військових дій буде зростати. Серед іншого важливим є набуття екологічної компетентності у фахівців природничих наук як майбутніх вчителів закладів освіти. Важливо не лише давати загальні теоретичні екологічні знання, а й вчити здобувачів використовувати набуті знання, як під час викладацької діяльності в майбутньому, так і у повсякденному житті.
Набуття екологічної компетентності фахівців природничих наук засобами цифрових технологій має не лише підвищити доступність екологічної освіти та розширити коло порушених питань, а й забезпечити формування чіткої позиції та практичних навичок.

Published: January 2025

У статті розглянуто проблему корекції мовлення у дітей з дизартрією засобами цифрових технологій.
Висвітлено погляди вчених на психолого-педагогічний потенціал цифрових технологій щодо корекції особливостей мовлення, які вказані у науковій літературі. Дослідники вбачають у цифрових технологіях навчання методологію і технологію освітнього чи навчально-корекційного процесу з використанням найновіших електронних засобів навчання, сукупність навчальних програм різних типів: від найпростіших до систем, що базуються на штучному інтелекті. Засоби інформаційної освіти – це засоби нових інформаційних технологій, зокрема й цифрові технології у сукупності з навчально-методичними, нормативно-технологічними й організаційно-інструктивними матеріалами, що забезпечують їхнє педагогічно доцільне використання.
Доведено, що граматична будова мовлення дітей з дизартрією характеризується незасвоєністю складних граматичних форм: місцевого відмінку, атипових форм, розмежування закінчень по типам відмін. Такі діти оволодівають граматичною будовою мовлення значно пізніше, ніж діти з нормальним мовленнєвим розвитком.
Проведено аналіз програмного забезпечення з погляду психолого-педагогічних особливостей його використання в навчанні дітей з порушеннями мовлення. Зазначено позитивні аспекти впровадження цифрових технологій, зокрема діагностичних програм для раннього виявлення порушень розвитку у дітей. Визначено основні пріоритетні напрями використання цифрових технологій навчання дітей з дизартрією. Порушення морфологічної системи мови у дітей із дизартрією виражається у суттєвих труднощах словозміни, що виявляється у великій кількості атипових словозмін, несформованості системи продуктивних словозмінних моделей, наявності варіативних замін афіксів, які розрізняються за значенням.

У статті досліджено проблему самореалізації особистості майбутнього вчителя музичного мистецтва у сучасному освітньому процесі. Розглянуто напрями професійного самовдосконалення важливих аспектів його професійної діяльності. Визначено, що формування готовності майбутніх вчителів музичного мистецтва до саморозвитку в творчій галузі потребує аналізу та обґрунтування освітніх умов, які створюються в освітньому середовищі.
Вказано, що сучасний професіонал вчителя має характеризуватися високим рівнем розвитку ціннісної свідомості, самосвідомості, духовної, моральної, інтелектуальної та методологічної культури, а також здатністю до співтворчості й творчості. Він є важливим суб’єктом освітнього процесу і головним вектором у будь-яких змінах щодо системи освіти.
Уточнено поняття «самореалізація» майбутніх учителів музичного мистецтва. Зазначено, що мета творчої самореалізації майбутніх вчителів полягає в трансформації змісту професійної підготовки для розвитку їхньої здатності до самостійної творчої діяльності, авторської ініціативи, майстерності у створенні власних музичних творів та повного розкриття їх художньо-творчого потенціалу. Визначено, що творча самореалізація вчителя музики передбачає творчий пошук, саморозвиток, професійний розвиток.
Окрім цього, в дослідженні було розглянуто форми творчої самореалізації. Наголошено, що творчі можливості для вчителів музичного мистецтва постійно розширюються завдяки розвитку технологій, міжнародному співробітництву, підтримці творчих ініціатив.
Доведено, що ефективність професійної самореалізації залежить від гармонійного поєднання цілей особистісного розвитку всіх учасників педагогічної взаємодії. Ключовим елементом цього процесу є творча настанова, що виявляється у прагненні до професійного самовдосконалення, самостійності та ініціативи.

Published: January 2025

The purpose of this study is to present a lightweight wearable (jeans) monopole antenna configuration for body area network (BAN) communication, breast and head tumors detections with back lobe reduction (i.e., low SAR), and it does so without introducing any special methodologies like as, AMC, EBG, HIS. The planned antenna has dual symmetrical slots as well as a ring-shaped slot (DSSRS) at the top, and it is in the form of a radiating rectangular patch with a ground plane. The design procedure has been finished with the help of CST MWS, and the next step will be to fine-tune the parameters of the antenna structure to achieve resonance at the ISM band (5.79 GHz). Testing for BAN, breast, and brain tumor detection was done using this prototype.

Beams of electrons confined in space are widely used in technological operations on welding, cutting, surface treatment. During the passage of electrons in matter, redistribution of beam energy losses occurs. The results of energy loss modeling using the Monte Carlo method presented in this paper demonstrate the redistribution of energy losses in the volume of the substance. There is an increase and then a decrease in energy loss as the electron beam moves deeper into the material. In the direction perpendicular to the beam axis there is an ex- pansion of the energy loss region and then a decrease in the diameter of this region. The presented calcula- tions well explain the results of synthesis of refractory dielectric ceramics. The redistribution of energy losses in the substance determines the morphology of the synthesized samples.

The article highlights the 50-year development of ELV electron beam accelerators at the Budker Institute of Nuclear Physics for industrial applications. ELV accelerators are used primarily for radiation modification of polymers, such as cable insulation, and are known for their high reliability, ease of use, and adaptability to various industrial needs. The evolution of these accelerators is traced from early models with 20 kW power to modern versions reaching up to 100 kW, and even a unique 400 kW machine. The article also discusses the integration of automated systems and specialized equipment that enhance the efficiency and quality of radia- tion-chemical processes. Applications include a wide range of industries, from telecommunications to nuclear power, where reliability under harsh conditions is essential. Despite past challenges, such as economic disrup- tions, the production of ELV accelerators continues to thrive, with over 220 units delivered worldwide. The institute is focused on advancing these technologies to meet future demands.

Thermoluminescent and dosimetric properties of ultrafine alumina and zirconia ceramics exposed to high- dose pulsed electron beam (130 keV, 1.5 kGy per one pulse) were studied. To synthesize ceramics with dif- ferent sizes of crystallites, the authors sintered nanopowder compacts in air in an electric furnace at T=700- 1700 оС, and exposed them to high-energy electrons (1.4 MeV) with high power density. It was found that ce- ramics annealing at Т>1000 оС greatly increases crystallite sizes, which correlates with a significant growth of intensity of thermoluminescent peaks. Maximum thermoluminescent response is present in the ceramics that were obtained with an electron-beam method. This is due to formation of radiation-induced trapping and luminescence centers during synthesis. Analysis of dose dependences of thermoluminescence of the irradiated a-Al2O3 и ZrO2 ceramics showed that these dependences are predominantly sublinear. Unlike their single- crystalline modifications, alumina-based ceramics have anomalous fading, which value increases as crystal- lites grow in size. The presence of the intensive isolated peak of thermoluminescence and sublinear character of the majority of dose dependences prove usability of the oxide ceramics synthesized in this work for meas- uring high doses of pulsed electron beams (unities-tens of kGy). Alumina-based ceramics require correction of thermoluminescent response by a fading value.

Ceramic samples of monocomponent (CaO, MgO, ZnO and WO3) and two-component (ZnWO4, MgWO4, CaWO4) compositions were synthesized by direct impact of high-energy electron flow on the charge of stoi- chiometric composition. Radiation synthesis of samples weighing about 50 g is realized in time of 10s with- out the use of any additional substances to stimulate the process. Systematic studies of the dependence of ra- diation synthesis of tungstate ceramics on the flux power density have been performed for the first time. It was found that the dependences of synthesis efficiency on the flux power density of monocomponent (CaO, MgO, ZnO and WO3) and two-component (ZnWO4, MgWO4, CaWO4) ceramic samples have the form of constantly increasing curves. There is a threshold above which the synthesis is realized for all synthesized samples. The effect of mutual influence of charge components on the efficiency of synthesis of two- component systems was found. Synthesis of ZnWO4, MgWO4, CaWO4 ceramics is realized under the same conditions of radiation treatment, while the thresholds of synthesis realization of one-component samples of CaO, MgO and ZnO and WO3 ceramics differ significantly. It is shown that at all used modes of radiation treatment the formation of ceramics with the same properties are realized. This effect is due to the inhomoge- neous distribution of electron flux energy losses in the substance. Synthesis of two-component (ZnWO4, MgWO4, CaWO4) ceramic samples is realized at the same power density above 1,0 kW/cm2. The radiation synthesis of the ZnWO4, MgWO4, CaWO4 ceramics is mainly determined by tungsten oxide.
Obtaining and studying the luminescent properties of zinc oxide synthesized in a stream of high-energy electrons

Published: January 2025

For the first time, zinc oxide samples were obtained by a method based on irradiation of nominally pure zinc with a stream of high-energy electrons with an energy of 1.4 MeV and a power density of 7 kW/cm2 in at- mospheric air. The morphology of the synthesized substance was studied by transmission electron and optical microscopy. Particles of ultrafine zinc oxide in the form of needles were found at a distance (1‒3) cm from the irradiation zone, with average lengths and diameters of 150 and 10 nm, respectively. Ultrafine samples are characterized by the presence of a hexagonal wurtzite structure. By optical microscopy, ZnO whisker micro- structures with a diameter of ~ 1 μm and a length of 50‒100 μm were detected in the irradiation zone. The photoluminescence spectrum of all samples is represented by one narrow exciton band with a maximum at λ
= 380 nm and a decay time of τ ˂ 13 ns in the absence of other bands due to intrinsic and impurity defects, which indicates the high crystalline perfection of the synthesized crystals.
Сlarification of the state diagram of “Metal 1-Metal 2” systems by analyzing the “cloud” of data of combustion parameters of “Metal 1-Metal 2-Nitrogen” SHS systems
Authors: Shkoda O.A.
Published: January 2025

The combustion of the “Metal 1 — Metal 2 — Nitrogen” systems in the layer-by-layer mode of self- propagating high-temperature synthesis was studied. A large amount of experimental data was obtained by changing the initial synthesis parameters. As a result, a “cloud” of data was obtained, and not a single curve. Since self-consistency of many factors that ensure the propagation of the combustion wave occurs in this sys- tem, the structure of the “cloud” of data obeys strict laws characteristic of dissipative structures of nonequilibrium nonlinear systems. Variations in the initial data made it possible to obtain changes in the combustion parameters in a wide range. The combustion parameters reflect the properties of the solid-liquid medium that is formed in the chemical reaction zone in the combustion wave. The combustion temperature is between the “liquidus” and “solidus” temperatures of the corresponding “Metal 1-Metal 2” binary phase dia- grams, where titanium, molybdenum, tungsten, and aluminum were used as the Metal. The resulting data “clouds” were compared with the corresponding phase diagrams of state.
It has been established that the shape and outline of the “cloud” of date for combustion parameters coincide with the shape and outline of the region bounded by the liquidus and solidus lines of the binary phase dia- grams of the state “Metal 1 — Metal 2”. Clarification in the phase diagrams of state has been carried out. The other arrangement of the liquidus and solidus lines on the melting diagrams of aluminum-tungsten and alumi- num-titanium is proposed.
