Alterität und maskiertes weibliches Schreiben in den Reiseberichten von Karl Eduard Zachariä [von Lingenthal]
Authors: Blioumi Aglaia
Published: February 2025

Es ist wenig bekannt, dass der deutsche Jurist und Byzantinist Karl Eduard Zachariä [von Lingenthal] in der zweiten Hälfte des 19. Jahrhunderts im Abstand von vierzig Jahren zwei Reisewerke verfasst hat. Die vergleichende Sichtung beider Werke im vorliegenden Beitrag ist dem Wandel des Bildes von Athen gewidmet, zumal im Kontext einer humanistischen Sichtung Athen schlechthin den symbolischen „Ort“ des klassischen Griechenlands verkörpert. Die Fragestellung des Beitrags betrifft konkret die Alteritätsformationen zwischen dem Eigenen und dem Fremden und ihre Verzahnung mit Aspekten weiblichen Schreibens, die vor allem im zweiten Buch zu konstatieren sind.
Die Rezeption der altgriechischen Philosophie bei G. W. F. Hegel vor dem Hintergrund des Philhellenismus
Authors: Iliopoulos Georgios
Published: February 2025

In diesem Beitrag soll ein Zusammenhang zwischen dem Philhellenismus des 19. Jahrhunderts und der Rezeption der altgriechischen Philosophie bei Hegel als herausragendem Vertreter des deutschen Idealismus hergestellt werden. Die Grundlage dieser vergleichenden Betrachtung besteht darin, dass dieses Kapitel deutscher philosophiehistorischer Aneignung seine Entstehung sowie seine konkrete Ausgestaltung einer Zeit verdankt, in der das vielseitige und umfassende kulturelle Phänomen des Philhellenismus seine Hochkonjunktur erlebte. In dieser Hinsicht können demnach Parallelen und Ähnlichkeiten zwischen philosophischer Rezeption und den allgemeinen, praktisch übergeordneten Tendenzen des Philhellenismus zum Vorschein kommen. Besondere Bedeutung kommt dabei der Hegelschen Rekonstruktion der philosophischen Vergangenheit Griechenlands insoweit zu, als es sich um eine im Grunde systematische Darstellung handelt, die – zumal im Hinblick auf relevante politische Anschauungen – dem seit der Aufklärung maßgeblichen Fortschrittsgedanken verpflichtet bleibt und diesen konkret zu rechtfertigen sucht.
Uterine stromal but not epithelial PTGS2 is critical for murine pregnancy success
Authors: Massri Noura , Arora Ripla
Published: February 2025

Use of non-steroidal anti-inflammatory drugs that target prostaglandin synthase (PTGS) enzymes have been implicated in miscarriage. Further, PTGS2-derived prostaglandins are reduced in the endometrium of patients with a history of implantation failure. However, in the mouse model of pregnancy, peri-implantation PTGS2 function is controversial. Some studies suggest that Ptgs2-/- mice display deficits in ovulation, fertilization, and implantation, while other studies suggest a role for PTGS2 only in ovulation but not implantation. Further, the uterine cell type responsible for PTGS2 function and role of PTGS2 in regulating implantation chamber formation is not known. To address this, we generated tissue-specific deletion models of Ptgs2. We observed that PTGS2 ablation from the epithelium alone in Ltfcre/+; Ptgs2f/f mice and in both the epithelium and endothelium of the Pax2cre/+; Ptgs2f/f mice does not affect embryo implantation. Further, deletion of PTGS2 in the ovary, oviduct, and the uterus using Pgrcre/+; Ptgs2f/f does not disrupt pre-implantation events but instead interferes with post-implantation chamber formation, vascular remodeling, and decidualization. While all embryos initiate chamber formation, more than half of the embryos fail to transition from blastocyst to epiblast stage, resulting in embryo death and resorbing decidual sites at mid-gestation. Thus, our results suggest no role for uterine epithelial PTGS2 in early pregnancy but instead highlight a role for uterine stromal PTGS2 in modulating post-implantation embryo and implantation chamber growth. Overall, our study provides clarity on the compartment-specific role of PTGS2 and provides a valuable model for further investigating the role of stromal PTGS2 in post-implantation embryo development.
THE INTRODUCTION OF COMICS ABOUT RUSSIAN-UKRAINIAN WAR IN EDUCATIONAL PROCESS
Authors: Derkachova Olga
Published: February 2025

The article deals with the study of Ukrainian comics devoted to the russian-Ukrainian war and their introduction in educational process. Creating a new modern reading space is an important problem today, especially after the full-scale russian invasion of Ukraine. Comics already become a part of the Ukrainian reading space, their creation is suggested by teachers to students like a task in lessons, and they are becoming more and more popular. The paper examines the history of the development of Ukrainian comics from the first to the latest, and analyzes the thematic and topical segments. The main focus is on “The Cyborgs” comics, social comics from Inker, educational projects “enWar Mental”, and “We'll Be Back Soon...”. Their plots, structure, and graphic design were analyzed. Each of them is based on real events. The series of comics “The Cyborgs” describes some episodes of the struggle for the Donetsk airport in 2014-2015, during which our defenders began to be called cyborgs for their courage, bravery, and strength. All the events and characters are real. The plots are based on the stories of the direct participants of those events. Inker comic series are also based on real events after February 24, 2022. The main heroes are the Ukrainians who resist the occupier, impress with their heroism and ability not to lose themselves in the war. “enWar Mental” (about the ecological consequences of war) and "We will soon return" (about forced migrants) are not comics in the classical sense, but rather educational projects, as the didactic component plays an important role in their stories: in the first one, the emphasis is on the formation of an eco-responsible personality, in the second on information hygiene and rules of conduct in the information space during war. Conclusions are made about the importance and necessity of introducing these comics into the Ukrainian educational process.
MODERN APPROACHES TO UPDATING THE PRIMARY EDUCATION CONTENT AND THEIR IMPLEMENTATION DIRECTIONS FOR THE DEVELOPMENT OF JUNIOR SCHOOL STUDENTS’ EMOTIONAL INTELLIGENCE
Authors: Kotyk Tetiana , Shkleda Lesia
Published: February 2025

The reorientation of the modern Ukrainian school from knowledgeable to competent one is aimed at forming students’ life experience, necessary knowledge, skills and values important for successful implementation in a rapidly changing society. The New Ukrainian school concept proclaims personality-oriented education, i.e. oriented not on the usual mastering of knowledge, but on the formation of the child's personality, his character and attitude to the world. The goal of education system modernization is to transfer the vector of child's external world cognition, created by nature and a man, to mastering the processes of interaction with this world, understanding the meaning of one's own activities. Therefore, the meaningful content of the educational process in primary school becomes particularly relevant in order to implement the New Ukrainian School tasks, especially in the aspect of the development of such student’s personal quality as emotional intelligence. The article reveals the prerequisites for the formation of modern approaches in the educational process organization, the structural components of the work content on the development of the primary school students’ personal worldview, the features of new approaches to the implementation of the primary education content and their personal value orientation and emotional components of education. The results of the analysis of software for the development of younger schoolchildren’s emotional intelligence, presented in current standard educational programs and the State Standard of General Primary Education of Ukraine are highlighted. We have come to the conclusion that the development of emotional intelligence of younger schoolchildren is a cross-cutting content line, i.e. a mandatory educational result which is formed by means of all educational branches and serves as a qualitative changes indicator in the primary education system.
DEVELOPMENT OF DISTANCE LEARNING IN HIGHER EDUCATION ABROAD IN THE HISTORIOGRAPHY OF UKRAINIAN PEDAGOGICAL SCIENCE
Authors: Snitovska Olha
Published: February 2025

The problem of developing distance learning in higher education in Ukraine became relevant at the intersection of the 1990s and 2000s. During its implementation, foreign experience in this area was actively studied. Thus, the historiography of Ukrainian pedagogical science has accumulated a significant array of various studies that require systematisation and comprehensive analysis. The purpose of the article is to analyse the historiography of Ukrainian pedagogical science on the development of distance learning in the higher education system abroad in order to identify the achievements, bottlenecks and prospects for further research on this issue. It has been determined that the dynamics of the historiographical process under study were marked by three main stages: 1) post-Soviet (1991 - 2000/2001); 2) pro-European (2002 - 2009/2010); 3) ‘globalist’ (since 2011-2012). The scientometric analysis of representative and special thematic bibliographic indexes allowed us to determine the dynamics of the development of research on the foreign experience in organising distance higher education, their thematic perspectives, and the views of scientists on the role of this problem in the structure of scientific and pedagogical knowledge. In addition to scientific articles, which constituted the vast majority (85-90%) of this array of historiographical sources, two to five or seven textbooks and approximately the same number of materials from scientific conferences appeared annually in it. A substantive analysis of representative monographs and theses has been carried out, which reflect the main trends and nature of the development of the historiography of Ukrainian pedagogical science on the organisation of distance learning in the system of higher education abroad. The conclusions indicate that with the appearance of the first studies on the problem under consideration in 1996/7, their growth during the second and third historiographical periods did not actually decrease, but their thematic perspectives changed. Despite the narrow regional studies orientation of such studies, their authors tried to comprehensively cover all the aspects of the development of distance learning in HEIs of foreign countries.
Corpos entre o paradigma ocidental e saberes afro-diaspóricos: o caso do Projeto CorpoFronteiras
Authors: Diniz do Couto Leonardo , De Carvalho Bastos Wanja
Published: February 2025

Este artigo é resultado de uma investigação ainda incipiente na educação física e noutras áreas do conhecimento que tomam o corpo humano como o seu objeto de interesse. Trata-se de uma investigação reflexiva sobre alternativas aos mandamentos das ciências consolidadas no Ocidente sobre saúde e beleza. O objetivo deste texto foi mostrar que, primeiro, epistemologicamente tais ciências da modernidade partem da compreensão do corpo das pessoas como coisa, separável da natureza, da cultura e da mente, entendendo-o tal como se fosse um objeto à espera do olhar investigativo das ciências que os destrincharão para descobrir seus segredos universalizáveis. E, segundo, pretendeu-se mostrar que outras compreensões sobre o corpo são possíveis. Para exemplificar essas alternativas foi apresentado o Projeto CorpoFronteiras — uma possibilidade de lidar com o corpo e a mente, singularizando-os, sem separá-los, e relacionando-os à sua ancestralidade, à natureza e à cultura em que se desenvolvem suas perspectivas e racionalidade.

Cuidado de si e técnicas corporais: implicações e contribuições na Educação Física — uma revisão sistemática
Authors: Oliveira Raimundo Geovana , De Oliveira Aguiar Milena , Costa da Silva Priscilla Pinto , Brandão de Souza Mendes Maria Isabel
Published: February 2025

O presente estudo teve como objetivo analisar as aproximações entre os conceitos de “cuidado de si” e “técnicas corporais” na produção de conhecimento, com vistas a trazer contribuições para a Educação Física. Trata-se de uma revisão sistemática, que consistiu em realizar buscas por artigos contendo os dois termos nas bases científicas PubMed, SciELO, ScienceDirect, Scopus, Citas Latinoamericanas en Ciencias Sociales y Humanidades e Web of Science. A conceituação dos termos ainda é escassa na produção de conhecimento analisada, entretanto, foi possível aproximar o “cuidado de si” e as “técnicas corporais” em alguns estudos analisados. Isso mostra que as técnicas corporais e o cuidado de si, para os seus praticantes, podem favorecer na qualidade de vida, bem-estar e questões psicoemocionais, sendo de grande relevância para a Educação Física. Além disso, as aproximações conceituais dos termos estudados são novas para essa área do conhecimento.

Impact of physical fitness on adolescent health and academic and cognitive performance: Systematic review
Authors: De Albuquerque Matheus Jacobs , Pasqualotti Adriano
Published: February 2025

Among adolescents, physical activity can also improve academic performance and cognitive outcomes. Research on the impact of school-based physical activity interventions on students’ academic performance is limited. This study conducts a systematic review of the impact of physical fitness and exercise on adolescent health, as well as academic and cognitive performance. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) method was adopted. The results indicate that aerobic exercise can enhance memory and attention, hippocampal metabolism, and academic performance in adolescents, along with other aspects of physical and mental well-being. Additionally, the importance of introducing school programs that encourage physical activity to prevent a sedentary lifestyle and enhance learning among this age group is emphasized.
El concepto de cuerpo desde la perspectiva de la psicomotricidad
Authors: Pellegrino María del Rosario
Published: February 2025

El cuerpo como objeto de estudio es abordado por diferentes disciplinas, y la psicomotricidad es una de ellas. De ahí que resulte necesario especificar su concepción acerca de éste. Dado que no hay una concepción del cuerpo única y homogénea ni siquiera dentro de la misma disciplina; el objeto de este trabajo es realizar precisiones sobre las formas de entenderlo como objeto de estudio, que permitan avanzar en la búsqueda de especificidad. Por ello, se elaboró una posible conceptualización general en la que se articularon aquellas nociones que resultan nodales para dicha perspectiva respecto a su modo de entender al cuerpo, a su construcción y a su funcionamiento. Entre las nociones centrales que dan soporte a esta concepción de cuerpo, se encuentra la importancia que otorga a la historia del sujeto en relación con los otros desde los primeros vínculos.
Cuerpo narrado: urdimbres y resistencias en clave performático escolar

Published: February 2025

El texto trasciende el relato del lenguaje intimista y alcanza la narrativa para problematizar los desarrollos de sentido y subjetividad que se encuentra en las prácticas docentes en la constitución de sí, pero también, de la pluralidad y externalidad en la voz de la maestra. Desde el cuerpo que se narra: el cuerpo sentipresente, sentipensante, que es ausencia en la presencia, en busca de sentidos para resignificarse en la condición como sujeto escolar que configura la existencia misma en la acción educativa y política del cuerpo narrado desde la performática escolar.
Shelf-life assessment of canola protein bio-adhesive

Published: February 2025

The storage stability of binders before their application is a crucial factor in the wood panel industry, as it impacts the mechanical properties, quality control, economic efficiency, and market competitiveness of the final products. In the present study, the long-term stability of two canola protein isolate (CPI) and two canola meal (CM) adhesive variants was investigated. The protein-based adhesives were prepared and tested on one-layer particleboards after one week, one month, two months, three months, and four months of storage of the formulations. Results indicate that the CPI-based outperformed the CM-based variants in terms of internal bonding strength (IB), modulus of rupture (MOR), and modulus of elasticity (MOE) due to the higher protein concentration of the CPI over the CM. While the IB strength of the CM-bonded particleboards was lower than the EN 319 requirement after the first four weeks of storage (0.34 N/mm2 and 0.29 N/mm2 for nitrite and bisulfate-crosslinked respectively), that of the CPI-bonded was still superior to the EN 319 after four months (0.44 N/mm2 and 0.3 N/mm2 for nitrite and bisulfate-crosslinked respectively). This indicates that the nitrite-crosslinked variants had a more robust chemical formulation, leading to stronger and more durable bonds.
«Dizen que le enseño el Ynga que él mismo se auía tornado otorongo»: Poder y transmutación en la imagen del jaguar durante el estado Inca y el periodo Colonial
Authors: Ortiz Luna Alejandro J.
Published: February 2025

Starting from the images of jaguars present in Inca and colonial pieces, and through the articulation of diverse sources, this work attempts to intersect Archaeology with relevant values and practices in native memory, which lead us to rethink the relationships between humans, animals and objects. The pieces and stories studied speak of the intergroup relations, the border spaces and the social dynamics that had the jaguar as a protagonist and intermediary in the framework of practices that consolidated the social order. Explaining to us that this successful process during the Inca expansion would have seen forced to adapt with Hispanic intervention, becoming visually enriched and preserving its essence. These lines constitute a way of approaching the interaction between the mechanisms of legitimation to the Inca political-religious power and the Andean-Amazonian fauna, questioning certain paradigms about the role it plays in the construction of culture, memory and territory.
Policy Reform, Movement Toward Universal Social Needs Screening, and Future Directions
Authors: Leary Jana C. , Garg Arvin
Published: February 2025

Pediatric clinicians can make a positive impact on some of the adverse social determinants of health that patients face. At the practice level amid recent policy reforms, we can implement family-centered social needs screening and referral strategies that are tailored to the pediatric setting. We do not need to start from scratch in these efforts; rather, we can leverage available screening tools, referral platforms, and implementation toolkits, as well as forge partnerships with community-based organizations to strengthen the social care we provide to our patients and families. Looking to the future, we can also think creatively about how to use information technology innovations in our screening and referral efforts to improve reach, efficiency, and effectiveness. Ultimately, no matter which approach a clinic or an institution takes to social needs screening and referral, we must strive to do so with an anti-racist lens. We must take the time to explain the universal nature of screening and our intent to understand patients’ lived experiences so we can provide equitable care. If we demonstrate empathy, humility, and non-judgment throughout this process, we may avoid unintended consequences from screening, strengthen our therapeutic relationships with caregivers and patients, and destigmatize social services.
Financial Assistance and Access to Care
Authors: Lax Yonit , Bouchelle Zoe , Vasan Aditi
Published: February 2025

Pediatric clinicians have long advocated for programs that provide families with financial assistance and support accessing health care, recognizing the potential impacts of financial need and decreased access to care on children’s health and well-being. In this chapter, we introduce pediatric health care providers to local and national programs that can provide financial support and improve children’s access to care. Specifically, we highlight programs that provide income support (eg, cash assistance, tax credits, employment services), address concrete resource needs (eg, nutrition programs, child care, and infant supplies), and support access to care (eg, health insurance, transportation, and internet access). We review eligibility criteria for these programs and outline practical steps providers can take to connect families to support. Finally, we discuss how pediatric providers can leverage research and patient stories to advocate for evidence-based local and national programs that reduce financial strain and bolster access to medical care for children and families.
Food Insecurity
Authors: Teli Radhika , Domaratzky Michaela , Duh-Leong Carol
Published: February 2025

Food insecurity is defined as unstable and unreliable access to adequate, nutritious food. In the United States, at least 1 in 7 children experiences food insecurity. Because this critical social determinant of health can have negative implications on child health and development, it is important for pediatric practitioners to screen for, and identify, food insecurity in children and their households by using the Hunger Vital Sign. Food insecurity has been shown to disproportionately affect high-risk groups, including racially marginalized groups and homes headed by a single caregiver. In the clinical setting, food insecurity can present in various ways, including nutrition deficiencies, less optimal child feeding behaviors, poorer mental health and academic outcomes, and higher rates of emergency department use. This chapter also summarizes resources available at the local, state, and national levels to address food insecurity and outlines possible strategies for managing food insecurity in the clinic setting. As we expand our understanding of food insecurity in the pediatric population, recommendations on how to best approach it will continue to evolve.
Social Care Interventions
Authors: Luke Michael J.
Published: February 2025

Health systems interested in screening for health-related social needs must first ensure they are equipped with accessible and family-centered intervention strategies to address any identified needs. Several factors, such as variability in severity of need among families and differences in resource availability based on geography, serve as considerable barriers to designing and streamlining social needs interventions. Some common strategies used in health care to overcome these barriers and address families’ needs include aggregated resource lists, in-person support to navigate these resources, and partnerships with community organizations that can offer resources directly. Over time, more and more creative models have been developed to address specific social need domains, which can serve as examples for any health system interested in designing its own interventions. Given the increasing overlap between medical and social care complexity in pediatric care, continued collaborative, family-centered, and community-engaged approaches will be critical to achieve health equity.
Medical Trainee Education Around Health-Related Social Needs
Authors: Berman Rachel Stein , Hassan Iman
Published: February 2025

In this chapter, we describe several frameworks for social determinants of health (SDOH) in medical education and specific strategies for teaching around the SDOH, with a focus on interdisciplinary training to engage with health-related social needs in the clinical setting. We include a model workflow for screening for social needs and placing referrals, discuss documentation of social needs and the plan to address them, describe strategies for communicating with patients about social needs in a trauma-informed and culturally humble way, and share cases that can be used for case-based learning. We discuss how clinical teams can make a bigger impact on addressing SDOH through research, performance improvement, and advocacy projects. Last, we describe methods to evaluate learners engaged in SDOH curricula and discuss future steps to advance medical training in this field.
The influence of solid-state welding modes on the structure of the 12Cr18Ni10-Cu system joint

Published: February 2025

This study investigates the friction welding technology for joining the 12Х18Н10Т stainless steel and copper, focusing on optimizing welding parameters and analyzing the mechanical properties of the resulting joints. The research was conducted using experimental methods to determine the optimal parameters of friction welding. Mechanical tests, including tensile strength, hardness, and microstructure analysis, were performed to evaluate the quality of the welds. The results indicate that proper selection of friction welding parameters significantly affects the quality of the joint between the 12Х18Н10Т stainless steel and copper. Optimal welding conditions were identified, leading to strong mechanical properties and reliable joint performance. Microstructural analysis revealed uniform material distribution across the weld zone. This study contributes to the understanding of friction welding processes and the effects of different welding parameters on the microstructure and mechanical properties of dissimilar metal joints. The findings provide practical recommendations for the friction welding of dissimilar materials, emphasizing the importance of parameter control to prevent defect formation and optimize joint strength. This study offers valuable insights into the friction welding process of dissimilar materials, highlighting the role of specific parameters in controlling the formation of defects and improving mechanical properties. The findings are applicable to industries requiring durable joints between stainless steel and copper. The study focused on a limited range of welding speeds and pressures. Future research should explore a broader set of parameters to further refine the welding process and address issues related to internal oxidation and joint durability.

Актуальність роботи пов'язана з вирішенням екологічних проблем, виникаючих при збільшенні кількості стічних промислових вод, забруднених важкими металами. Мета роботи полягала в обґрунтуванні та визначенні ефективності функціональних матеріалів для очищення вод від іонів важких металів. Експериментально підтверджена можливість одержання мідно-цинкових феритних матеріалів із сульфатного мідно-цинкового електроліту методом співосадження за співвідношення вихідних молярних концентрацій компонентів ∑(Cu2+ + Zn2+) : Fe3+ = 1 : 1. Визначено основні стадії отримання мідно-цинкових феритних матеріалів: змішування відпрацьованого сульфатного мідно-цинкового розчину з з кристалічною сіллю Fe(ІІІ); утворення гідроксидів металів; введення реагенту Na2SO3 для утворенням γ-Fe2O3; барботування киснем повітря; відокремлення отриманих феритів від елюату та їх промивання; визначення складу отриманих феритів. Досліджено склад та фізико-хімічні властивості отриманого феритного композиту. Доведено, що присутність феритних фаз у вигляді шпінелі із загальною формулою FexZnyCuzO4 і складна розвинена текстура поверхні нанокомпозита можуть характеризувати їхні ефективні сорбційні властивості. Доведено ефективність сорбційних властивостей феритного композиту, які зумовлюють швидку кінетику та різке зменшення концентрації іонів Cu(ІІ) у часі при різних відношеннях мас феритних композитів та іонів Cu(ІІ) у розчині (n) та проведенні сорбції в стаціонарному режимі. За допомогою апроксимації кривих та аналізу даних CurveExpert Professional запропановано математичну модель, яка дозволяє за будь-якої концентрації іонів Cu(ІІ) в розчині розрахувати сорбційну обмінну ємність, що характеризує ступінь відпрацювання сорбенту.
ПІДВИЩЕННЯ ЕЛЕКТРОХІМІЧНОЇ АКТИВНОСТІ ЕЛЕКТРОДНИХ МАТЕРІАЛІВ НА ОСНОВІ НІКЕЛЮ ШЛЯХОМ КОРОЗІЙНОЇ ОБРОБКИ

Published: February 2025

Останнім часом значну увагу приділено вивченню каталітичних властивостей і хімічному синтезу халькогенідних матеріалів, зокрема сульфідів металів групи заліза. Особливий інтерес викликають сульфіди нікелю, зокрема такі, що за стехіометрією відповідають природнім мілериту та хізлевудиту. Ці халькогенідні сполуки характеризуються високою електропровідністю, порівнянною з провідністю чистого нікелю, а також значною каталітичною активністю в процесах електровідновлення кисню. На основі даних циклічної вольтамперометрії встановлено, що збільшення тривалості корозійної обробки блискучих нікелевих осадів, що містять сульфур, в концентрованій оцтовій кислоті сприяє підвищенню поверхневого вмісту сульфуру, що, у своєю чергою, призводить до зростання густини струму на циклічних вольтамперних кривих. Аналогічно, обробка безсульфурних нікелевих осадів у насиченому розчині сульфіду натрію також сприяє збільшенню катодної густини струму. Отже, незалежно від способу обробки, утворення сульфідів нікелю чи адсорбція сульфуру на поверхні електродного матеріалу забезпечує підвищення його електрохімічної активності. Таким чином, вперше показано, що в обох випадках, як після корозійної обробки блискучих сульфоровмісних нікелевих осадів в оцтовій кислоті, так і під час адсорбційної обробки безсульфоровмісних нікелевих осадів в насиченому розчині сульфіду натрію відбувається стабілізація величини катодної густини струму після 24 годин проведення обох видів обробки. Відповідно катодна густина струму в даному випадку є параметром, що визначає електрохімічну активність досліджуваних матеріалів. Показано, що сульфіди нікелю, які утворюються під час корозійної обробки, є найбільш стійкими та ефективними для електровідновлення кисню в помірнолужному середовищі.
Hypereides: Verteidigungsrede für Euxenippos gegen Polyeuktos wegen Landesverrats– Zur Frage der Datierung
Authors: Horváth László
Published: February 2025

Hypereides' In defence of Euxenippus against Polyeuctus upon his indictment for treason was dated by its first editor Churchill Babington to the year 334 BC, while the second editor, Domenico Comparetti, places the possible date of composition almost ten years later, to the period between 330 and 324 BC. According to Comparetti, the orator could only have quoted the expression ‘Molossia is mine’ from the letter of Alexander's mother Olympias to the Athenian people at the time when Olympias was already ruler of the territory in question, i.e. after the death of her brother in 331 BC. This date has been accepted as the factual date of composition for over 150 years, so editors have adapted several emendations and alternative interpretations to this view. This study argues that the speech should be dated to 334/333 BC according to the surviving, clearly interpretable text and that any emendations are therefore superfluous – Churchill Babington was right.

Published: February 2025

ABSTRACT Purpose: to characterize unhealthy oral habits and oral health-related quality of life in a group of children from Santiago, Chile, comparing these results by sex and the presence or absence of unhealthy oral habits. Methods: parents/caregivers of 100 boys (4.06±0.7 years old) and 92 girls (4.09±0.7 years old) from preschools answered the Unhealthy Oral Habits Identification Instrument and the Early Childhood Oral Health Impact Scale via Google Forms. Results: altogether, 63.3% had one, and 16.9% had two unhealthy oral habits; 57.6% used a bottle with a regular nipple. The mean Early Childhood Oral Health Impact Scale score was 16.5 out of 52 points. Quality of life did not differ significantly between children with one or more habits and those without unhealthy oral habits. Conclusions: bottle use with a regular nipple was the most prevalent habit. Quality of life had a greater impact on children at a functional level, with no significant differences by sex or in quality of life, based on the presence or absence of unhealthy oral habits.

Published: February 2025

Dealing with aleatoric uncertainty is key in many domains involving sequential decision making, e.g., planning in AI, network protocols, and symbolic program synthesis. This paper presents a general-purpose model-based framework to obtain policies operating in uncertain environments in a fully automated manner. The new concept of coloured Markov Decision Processes (MDPs) enables a succinct representation of a wide range of synthesis problems. A coloured MDP describes a collection of possible policy configurations with their structural dependencies. The framework covers the synthesis of (a) programmatic policies from probabilistic program sketches and (b) finite-state controllers representing policies for partially observable MDPs (POMDPs), including decentralised POMDPs as well as constrained POMDPs. We show that all these synthesis problems can be cast as exploring memoryless policies in the corresponding coloured MDP. This exploration uses a symbiosis of two orthogonal techniques: abstraction refinement—using a novel refinement method—and counter-example generalisation. Our approach outperforms dedicated synthesis techniques on some problems and significantly improves an earlier version of this framework.
Contact-scale insights into the shear stiffness of non-spherical granular materials

Published: February 2025

Small-strain shear stiffness (G0) is an essential parameter to predict deformation characteristics and dynamic properties of granular materials. It is empirically known that G0 increases with decreasing a void ratio (e0) and increasing isotropic stress level (p0′). Recently, the effect of particle shape on G0 has been studied; however, the mechanism underlying the evolution of G0 is not fully understood. Using the discrete element method (DEM), this contribution quantifies the G0 of granular materials by performing small-strain probing where multi-sphere clumped particles are used to vary particle shape and surface topology systematically. The Hertzian contact theory is applied for each sphere-element contact to capture the stress-dependent contact stiffness. The results reveal that G0 is well correlated with e0 or mean coordination number for a given particle shape; however, G0 is measurably reduced when finer sphere-elements dominate inter-particle contact responses. The present study proposes two contact-scale expressions of G0 for non-spherical particles based on contact area (CA) and micromechanical effective medium theory (EMT) by extending the EMT expression for spherical particles; both can capture the effects of particle shape and p0′ on G0 under given conditions where particle breakage does not occur.
Dike flow and heat transfer with geomembrane defects: experiment and simulation

Published: February 2025

The damage of geomembranes in dikes can result in leakage. In order to investigate the efficacy of heat tracing in the detection of geomembrane defects, a series of laboratory experiments were conducted utilising a self-made 2D sand trough and temperature sensors. The heat tracing response of geomembrane defects was evaluated. The findings indicate that the temperature distribution within the dike, resulting from geomembrane defects, exhibits a comparable spatial-temporal pattern to that of the seepage field. Furthermore, the heat tracing response is discernible. A flow-heat coupling model (FHCM) was constructed based on the heat transfer theory of porous media and the saturated-unsaturated seepage theory. The accuracy of the FHCM was tested by combining the laboratory experiment results. The The numerical simulation results show that the superposition of multiple geomembrane defects results in an acceleration of leakage. In order to reduce the amount of debugging work required for model parameters, the Morris method was employed to analyse the global sensitivity of six parameters within the FHCM. It was determined that the parameter exhibiting the greatest sensitivity is hydraulic conductivity. This work provides a reference for the wide application of heat tracing technique.

Objective. To develop the personalized model for predicting the risk of acute pancreatitis after endoscopic transpapillary interventions. Material and methods. A retrospective analysis of treatment outcomes included 366 patients with benign and malignant pancreaticobiliary diseases who underwent endoscopic transpapillary interventions. Risk factors associated with patients, underlying diseases and interventions were analyzed. Logistic regression analysis was used to present the personalized model for predicting the risk of acute pancreatitis. Results. Female gender (p=0.028), age <40 years (p=0.001—0.018), calculous cholecystitis (p=0.010) and stenosis of the major duodenal papilla (p=0.008) are patient-associated risk factors of acute postoperative pancreatitis. Stenting of the main pancreatic duct and thoracic epidural analgesia reduced this risk by 6.5 and 4.6 times, respectively. We developed significant (p<0.001) regression model to determine the likelihood of acute post-manipulation pancreatitis. Conclusion. Original prediction model is valuable to determine the risk of acute pancreatitis after endoscopic transpapillary interventions. This model justifies various methods to prevent this complication.

Objective. To identify prognostic factors and role of preoperative therapy for resectable intrahepatic cholangiocarcinoma (IHCC). Material and methods. We analyzed the results of surgical and combined treatment of IHCC between 1999 and 2023. Immediate and long-term outcomes were evaluated depending on negative prognostic factors and additional therapy. Results. The study included 195 patients. Postoperative complications grade ≥III were observed in 35 (17.9%) case. Mortality rate was 3.1% (n=6). Thirty-eight patients (19.5%) underwent treatment before surgery, 109 (55.9%) ones — after surgery. The median overall survival was 31 months, 5-year overall survival — 32.0%. The following factors worsened overall survival: node size ≥8 cm (HR 1.45; 95% CI 0.97—2.17), invasion (HR 1.63; 95% CI 1.07—2.47), multiple lesion (HR 1.51; 95% CI 1.00—2.28). R1 resection worsened disease-free survival (HR 1.88; 95% CI 1.14—3.10). Lymph node metastases decreased overall (HR 1.96; 95% CI 1.27- 3.04) and disease-free survival (HR 2.37; 95% CI 1.63—3.44). Two and more negative factors worsened overall (p=0.0013) and disease-free survival (p=0.0005). Absence of adjuvant therapy worsened overall (HR 2.12; 95% CI 1.41—3.20) and disease-free survival (HR 1.42; 95% CI 0.99—2.04). There was a trend towards higher overall (p=0.088) and progression-free survival (p=0.029) in case of preoperative therapy (n=195). In unfavorable prognosis group, preoperative therapy (n=33) was superior to standard treatment (resection+capecitabine after surgery, n=26). There was a trend towards higher overall survival (p=0.066) and significantly better progression-free survival (17 vs 13 months, p=0.018). Conclusion. Negative prognostic factors for resectable IHCC are lesion size ≥8 cm, intrahepatic and regional metastases, invasion into neighboring structures, R1 resection. Combination of negative factors worsened prognosis. Adjuvant therapy improved postoperative outcomes. Preoperative therapy may be advisable in case of negative factors and high risk of R1 resection.

Published: February 2025

We present simultaneous aortic valve reimplantation, replacement of aortic arch, right common carotid artery and proximal parts of the right subclavian and left common carotid arteries in a patient with type I aortic dissection. Involvement of supra-aortic arteries is the main predictor of cerebral malperfusion and mortality in acute aortic dissection. Optimal surgical intervention in such patients is still unclear. Moreover, patients with acute ascending aortic dissection rarely undergo valve-sparing surgery, since such interventions require much time and prolong myocardial ischemia.

Forfeiture to the State: Using Grammar to Interpret Section 35 of the Criminal Procedure Act
Authors: Carney Terrence R
Published: February 2025

Section 35(1)(a) of South Africa's Criminal Procedure Act 51 of 1977 allows a court of law to declare items forfeited to the state if they were used as weapons or instruments in aid of committing an offence. However, it is not always clear what qualifies as potential instruments of crime or what the proximity of the instrument is to the offence. For the purpose of statutory interpretation, this contribution identifies a grammatical construction frequently present in abstractions of offence descriptions as a means to identify an instrument and its direct involvement in an offence. It takes the form of the construction, "X does Y to Z with A", which contains the instrument prepositional phrase "with A". Read with other thematic roles like "Agent" and "Patient", the statutory interpreter should be able to determine both the relevant instrument role and its potential to affect a change in the object of a sentence, suggesting direct involvement. To better understand the grammar, this contribution modestly explains the Cognitive Linguistic approach to argument structure and thematic roles and briefly summarises Ronald Langacker's "action chain" model. The grammatical construction is then applied to examples taken from South African and Dutch case law dealing with forfeiture to illustrate its potential as a tool for interpretation.
