Az egységes pedagógusképzés koncepciója és kivitelezésének lehetőségei a Veszprémi Egyetemen
Authors: Zsolnai József
Published: November 2024

A koncepció részben a Veszprémi Egyetem rektorának kérésére készült, részben pedig az egységes tanárképzés szervezési és szervezeti kérdéseit tárgyaló, az oktatási miniszter mellett működő és Hunyady György által vezetett bizottság megbízásából. Az általam írt előteijesztés a Veszprémi Egyetem Tanárképző Karának Pedagógiai Kutatóintézetében készült, az általános megközelítés mellett mérlegelte a Veszprémi Egyetemen történő egységes pedagógusképzés kivitelezésének lehetőségeit is.
Az előterjesztés harminckilenc oldalnyi terjedelmű. A XXI. század jövőképével, a tudástársadalom és a tanulótársadalom kihívásaival indító tanulmány a közép-európai régiót érintő Európai Uniós csatlakozás pedagógusképzési kihívásainak elemzéséig jut el. Részletesen tárgyalja a magyar közoktatás jellemzőit és az egységes pedagógusképzés összefüggéseit. Sor kerül a pedagógusképzés helyének, szerepének vizsgálatára a magyar felsőoktatásban, a szervezetfejlesztési, minőségbiztosítási és akkreditációs folyamatok továbbfejlesztési lehetőségeinek áttekintésére. Kitüntetett figyelemmel kezeli a neveléstudomány (pedagógia) fejleszthetőségének szerepét a közoktatás és a pedagógusképzés professzionalizációjában, különös tekintettel az egységes pedagógusképzésre. Számba veszi az egységes pedagógusképzés kimunkálásához, egyáltalán a pedagógus szakma fejlesztéséhez szükséges feltételek megteremtésének fő problémáit. Az anyaghoz kapcsolódó függelékekben a bolognai modell alapján szerveződő egységes pedagógusképzés első és második ciklusának alapvető jellemzői kerülnek bemutatásra, illetve az egységes pedagógusképzés koncepciójának kivitelezhetősége a Veszprémi Egyetemen, valamint a hiányzó pedagógusszakmák listája. Az eredeti előteijesztés címe: A magyarfelsőoktatás keretei között életre hívandó egységes pedagógusképzés koncepciója. Ebből a koncepcióból a folyóirat terjedelmi lehetőségeihez igazodva az eredeti tanulmányból csak a pedagógusképzés szerkezetét befolyásoló tényezőket áttekintő és a veszprémi modellt leíró részek kerülnek közlésre.

Tehetséges tanárok a tehetségekért
Authors: Gyarmathy Éva
Published: November 2024

A tehetséggondozás egyik nagy problémája, hogy a tehetség mibenléte nem definiálható pontosan. így a tehetségek azonosítása is csak a teljesítményen keresztül valósulhat meg. Ehhez tehetséggondozó programokra és megfelelően képzett tehetséggondozókra van szükség. A tehetséggondozó a tehetségekhez nagyon hasonló tulajdonságokkal, átlag feletti képességekkel, kreativitással és motivációval kell, hogy rendelkezzen. Számos szerepet kell elvállalnia, így edző, menedzser, mentor, tanácsadó és szülői csoportok vezetője. A tehetséggondozók képzésében a tehetséges gyerekek fejlesztésében használt módszereket alkalmazzuk, hogy mintát és sajátélményt kapjanak ezen hatékony eszközök tekintetében.
Természettudomány szakos tanárképzés
Authors: Victor András
Published: November 2024

A komplex világlátás igénye — nem csak a természettudományok terén — egyre erősebb. A kis óraszámú természettudományos tárgyak oktatását jól (és gazdaságosan) elláthatnák olyan tanárok, akik mind a négy természettudomány (fizika, kémia, biológia és földrajz) terén rendelkeznek a szükséges szaktárgyi és tantárgypedagógiai ismeretekkel. A Természettudomány szak bevezetését főiskolai szinten és mindig valamely hagyományos természettudományos szakkalpárosítva tartjuk lehetségesnek. Kidolgoztuk ennek a tervezett szaknak az óratervét és a tematikáit. A komplexitásból is adódóan a környezeti nevelés nagy hangsúlyt kap a tervezetben.

A természettudományi szakos pedagógusok képzése és a NAT
Authors: Nahalka István
Published: November 2024

A Nemzeti alaptanterv 2003-as változatának elkészítése közbenjelentős vitákat váltott ki az a döntés, hogy a közoktatás tartalmi szabályozásának ez a legfelső szintű dokumentuma nem fogalmazza meg az egyes évfolyamokon tanítandó ismereteket, vagyis a tananyagot. Ez a megoldás jelentős mértékben befolyásolja a pedagógusképzést, hiszen a leendő tanítók és tanárok képzése során a felsőoktatási intézmények nem támaszkodhatnak egy egységes, részletesen szabályozott tananyagra. A szakmódszertani oktatás új feladata lesz ebben a helyzetben annak alapos átgondolása, hogy milyenfeladatokra és milyen módon kellfelkészítenie a leendő pedagógusokat, ha nem a mindenkire kötelező, általánosan érvényes tananyag tanítása áll a hallgatók felkészítésének középpontjában. E tanulmányban érveketsorakoztatunk fel a megoldás, vagyis a tananyag kihagyása mellett, s az egyik műveltségi területen, a természettudományos nevelés területén bemutatjuk, hogy mi az, ami adott a NA T-2003-ban, s hogyan befolyásolhatja az egyetemi ésfőiskolai képzést is.

Analytical methodologies for the determination of sterigmatocystin in food and current concentration levels
Authors: Pardo Olga , Esteve-Turrillas Francesc A.
Published: November 2024

Sterigmatocystin (STE) is a possible human carcinogenic compound (2B) according to the International Agency for Research on Cancer classification. Structurally, STE is a precursor to aflatoxins, sharing a similar polyketide-derived biosynthetic pathway, which underscores its toxicological relevance. It has been reported to occur in a variety of foodstuffs including cereals and cereal-based products, spices, cheese, and nuts, among others. STE poses a substantial challenge to food safety and addressing this issue requires a comprehensive strategy encompassing prevention, monitoring, and regulation to protect both human and animal health from its harmful effects. The present paper presents the analytical methodologies for the determination of STE in foodstuffs and the reported levels of STE in food, based on a review of scientific publications from 2021 to 2024. Significative progress has been made in the development of analytical methodologies for STE determination in food; however, further advancements in analytical techniques, standardized protocols, and monitoring are essential to improve risk assessment and guide effective mitigation strategies.
Pinaceous evolution illuminated by additional diversity of Early Cretaceous seed cones
Authors: Rothwell Gar W. , Stockey Ruth A.
Published: November 2024

An anatomically preserved fossil conifer seed cone has been discovered near Ono, California, providing additional evidence for the diversification of Pinaceae during the Aptian Stage of the Early Cretaceous. The specimen was measured and photographed, and then serial anatomical thin sections were prepared by the cellulose acetate peel technique. Selected peels were mounted on microscope slides, viewed, and photographed with transmitted light microscopy. Structure of the seed cone is similar to that of living and extinct representatives of the Pinaceae in the occurrence of helically arranged and imbricating foliate bract/scale complexes consisting of a small bract that subtends an ovuliferous scale bearing two inverted winged seeds on the adaxial surface. However, details of bract/scale complex vasculature, a wing that is obviously lateral to the seed body, and distinctive histological features reveal that this cone represents a new genus of extinct Pinaceae. This new genus of fossil conifers, represented by a seed cone of unique structure, further enriches the known diversity of Early Cretaceous Pinaceae. When added to the existing record of fossil seed cones, the new genus and species, Onostrobus elongatus Rothwell et Stockey, highlights knowledge that among early-diverging lineages of Pinaceae there has been considerable Cretaceous and Paleogene evolution that is reflected by variations among subtle characters that are recognizable only from anatomically preserved specimens.
Anisopteris shuteana sp. nov., a fertile adpression fossil from the Mississippian (lower Carboniferous) of Teilia Quarry, North Wales, UK
Authors: Hayes Peta Angela , Pearson Hugh Lance
Published: November 2024

Anisopteris shuteana Hayes et H.L.Pearson sp. nov., a rare fertile adpression fossil, is described from the Mississippian of Teilia Quarry, Gwaenysgor, North Wales, UK. The new species is based on material from the Margaret Benson Collection and named in honour of Cedric H. Shute who curated the Palaeobotany Collections at the Natural History Museum, London. The account arises from an unpublished typescript by Benson, who considered the specimen to be a fern fructification. A. shuteana is of particular importance because only two fertile fronds of Anisopteris have previously been described. Detailed comparisons are drawn between these two species, Anisopteris fertilis (J.Walton) Hirmer, 1940 and Anisopteris lindseaeformis (Bunbury) Hirmer, 1940 and A. shuteana, which is assigned to the Lyginopteridales.
Lower Devonian Tortilicaulis is an early tracheophyte and not a bryophyte
Authors: Morris Jennifer L. , Edwards Dianne , Axe Lindsey , Crooks Tom , Murdock Duncan , Donoghue Philip C. J.
Published: November 2024

Tortilicaulis D.Edwards is a genus of long-standing unknown affinity in which there are two species: the holotype T. transwalliensis D.Edwards, known only from coalified compressions and T. offaeus D.Edwards, Fanning et J.B.Richardson, known from an assemblage of minute, exceptionally well preserved charcoalified fossils from a Lochkovian deposit in the Welsh Borderland. It has previously been interpreted as bryophyte-like after comparisons based on twisted cells in both stems and sporangia were made with certain extant liverwort and moss genera, there being no evidence of vascular tissues. It has previously been grouped within the horneophytes in cladistic analyses. Subsequent studies of T. offaeus confirmed the presence of stomata on their isotomously branching stems and dehiscence of the sporangium into two valves, but the absence or presence of tracheids has not been demonstrated. Despite numerous attempts to observe the internal anatomy of stems through physical splitting followed by scanning microscopy, we turned to synchrotron radiation x-ray tomography microscopy. Here we describe five Tortilicaulis specimens that were selected for scanning and demonstrate simple annular tracheids within their twisted stems. We conclude that Tortilicaulis was an early diverging tracheophyte, although whether a member of the stem or crown group awaits further detailed cladistic analyses. While architecturally similar to Psilophyton Dawson, the hypothesis that Tortilicaulis was ancestral to the trimerophytes remains unproven.

Organizational Necrosis Autopsy: How Extremist Openness Can Threaten Open Organizing
Authors: Langlois Margaux
Published: November 2024

Existing research highlights the imperative nature of addressing inherent tensions when implementing organizational openness, necessitating actors to navigate explicit or implicit emergent closure mechanisms. However, certain literature warns against the absolute conception of openness prevalent in academic and practical spheres. This article thus explores what occurs in organizations that eschew closure mechanisms in favor of openness. I draw on the ethnographic inquiry of Managers du 21e siècle, a non-profit organization championing openness as a pivotal organization tenet, whose existence has come under threat amidst escalating crises. The metaphor of organizational necrosis serves to highlight that an extremist pursuit of open principles can hamper action by fostering depersonalization, to align with extremist open values, and triggering disempowerment, through strategies that deflect conflicts of value. My first contribution emphasizes the detrimental repercussions of an extremist openness paradigm on organization sustainability. The second explores how medical metaphors can assist in grasping organizational decline.

Domain Generalization Prognosis Method for Lithium-ion Battery State of Health with Transformer and Multi-kernel MMD
Authors: Zhu Yafei , Guo Tianyi , Li Xiang , Zhang Yewei , Zhang Wei
Published: November 2024

In recent years, a number of intelligent algorithm have been proposed for forecasting the lithium-ion battery state of health (SOH). Due to the varying specifications and operating conditions of batteries, it is difficult to anticipate the health condition of lithium battery as it begins to deteriorate. There are still few studies on health state prediction models for different types of batteries. In this paper, 40 battery data from 5 public datasets are selected to carry out research, and a model architecture consisting of Denoising Autoencoder and Transformer is designed. One or two types of battery packs are identified as the source domain, and multiple types of battery packs are identified as the target domain. By employing Maximum Mean Discrepancy (MMD) on the Transformer architecture, the source and target domains were evaluated and found to converge as training continued. Finally, 29 transfer learning combination tasks were constructed. Results show that the model built with two kinds of batteries as the target domain has the best prediction accuracy and excels in prediction and is versatile in its application. The experimental results also reveal that this study provides a promising tool for predicting Lithium-ion batteries' SOH and strives to build a generalized model of the Lithium-ion batteries' SOH indicators.

E-Learning Methodology: Technology and Livelihood Education Teachers’ Affordances and Limitations
Authors: T. Yubal Janet
Published: November 2024

This study aimed to explore the implementation of E-learning methodology based on the perspective of TLE teachers. This study employed a phenomenological research design which aims to determine the experiences and perceptions of the seven (7) participants. Three themes emerged from the experiences of TLE teachers in implementing the E- learning methodology. The three themes were flexibility and convenience, delayed communication and unavailability of technical support from teachers. Meanwhile, on the coping mechanism of teachers the themes generated were willing to take professional development, addressing technical problems at a different angle and utilizing more mechanisms towards efficient communication. Further, the following are the themes generated from the insights drawn from the experiences of the teachers which were realistic optimism, provision of authentic learning, and collaboration and cooperation. The results implied that school administrators design teachers’ readiness program on E-learning methodology based on the empirical results of this study. Moreover, the results generated provided comprehensive data in conducting future research with similar or relevant scope. This will yield advantageous findings tailored to the organization and hierarchical context of the education sector.
Evaluation of Peri Menopausal Syndrome at the Age Group of 43-48 Years. A Study from Tamilnadu, India
Authors: Anusha R. , Christuraj P. Allwin , Shrimathi Jenifer , Hema I. , Sakthi S.
Published: November 2024

The perimenopause, sometimes referred to as the menopausal transition, is associated with significant changes in hormones and reproduction. Both these changes and the symptoms that go along with them have been well documented. The perimenopause is an ill- defined time frame that surrounds advancing years of a woman's reproductive life. The onset of irregular menstruation and its cessation after a year of amenorrhea constitute the final menstrual cycle. This study was conducted at the Sree Ramakrishna Medical College of Naturopathy and Yogic Sciences and Hospital in Kulasekharam, Tamil Nadu, India. The study's female participants were between the ages of 43 to 48. Following the description of the investigation's goals, vocal agreement was achieved. This survey had thirty responses. In this study the questionaire were consists of thirty questions such as hot flashes, thirst, pain, increased bleeding, and an unpleasant mood . Female participants who were unwilling or uncooperative were not included in the study. Many women find the menopausal transition to be a challenging time in their lives. If they lost any of their human potential, it would be catastrophic for both individuals and society. Therefore, it is essential to keep working to comprehend how perimenopause fits into women's lives and to predict and treat the common and uncommon symptoms that could lower their quality of life. Future health care initiatives should concentrate on these areas to enhance the general health and well-being of perimenopausal women.
Cultural Integrations for Organisational Performance: Synthesising Western Liberal, Sinocentric and Ubuntu Perspectives in South African Career Management Services
Authors: Sikwela Shereen , Diedericks Melvin
Published: November 2024

South African public organisations intrinsically integrate diverse cultural perspectives by embracing and promoting developmental state ideals, democratic principles of equality and fairness, and communitarianism in their governance frameworks. This embrace reveals the interplay of Western Liberal principles, Sino-centric values, and Ubuntu cultural perspectives in influencing organisational performance. This paper thus explored these dynamics by examining how conflicting and integrating perspectives affect and enhance career management practices for organisational performance. Key cultural themes, including individual autonomy, hierarchy, collaboration, societal order, and communitarianism, were reviewed at the North West Province Departments of Cooperative Governance, Traditional Affairs, and Human Settlements through mixed methods research. Findings revealed cultural conflicts culminating in unfairness in career management practices and a lack of collaborative efforts by role players involved. These findings underscored the necessity of weakening and integrating strong ontologies through panentheism to enhance economic and employee development, societal order, hierarchy, and communal well-being through structured governance, pluralist choice, collective fingers and societal order frameworks. This research offers practical implications for improving organisational performance in African multicultural contexts, which are valuable for career management and public administration professionals.

Assessing the impact of the Russia-Ukraine war and COVID-19 on selected European currencies and key commodities
Authors: Aliu Florin , Apanovych Yelyzaveta , Bajra Ujkan , Nuhiu Artor
Published: November 2024

This study measures the spillover effects of the Russia-Ukraine war and the COVID-19 pandemic on currency pairs as the Russian ruble, Czech koruna, Polish zloty, Hungarian forint, Swedish krona, Bulgarian lev, Danish krone, Romanian leu, Ukrainian hryvnia, and Turkish Lira. By employing the TVP-VAR model we investigate the dynamic connectedness among these currencies and key energy and agricultural commodities. The data series encompasses two consecutive non-economic shocks – the Ukraine war and the COVID-19 pandemic – and a preceding period of general stability during 2018 and 2019. The importance of geopolitical context in shaping currency dynamics was present in countries with heavy dependence on Russian gas. The findings indicate a limited direct impact of commodity price fluctuations on the value of these currencies. At the same time, geopolitical decisions primarily related to the Russian Ruble and energy dependencies significantly impacted their valuation. The study reveals the complexity of currency dynamics and the influence of geopolitical risks and global health crises on exchange rate volatility and commodity dependencies.
The New GGBN Data Portal and GGBN Stable Identifiers
Authors: Droege Gabi , Güntsch Anton
Published: November 2024

The Global Genome Biodiversity Network (GGBN) Data Portal plays an important role in the global biodiversity informatics infrastructure by providing standardized access to 3.8 million DNA, tissue, and environmental samples as well as 2.4 million associated vouchers and cultures from 39 repositories. In addition, more than 3.5 million references to sequence data can be derived from these records and are accessible through the GGBN Data Portal. By making all these resources available in one portal, GGBN is bridging the gap between sequences, samples and vouchers based on well curated physical collections.

In order to increase the usability and interoperability of GGBN data, stable identifiers have been developed based on the Consortium of European Taxonomic Facilities (CETAF) stable identifiers (Güntsch et al. 2017). Each GGBN stable identifier represents a physical object in our member collections, e.g., a sample or voucher.

The landing pages for these identifiers will be embedded in a new version of the GGBN Data Portal, which will be launched by the end of 2024. The portal underwent a complete redesign of the user interface, especially the search and members pages. In addition to the stable identifiers, it will then also be possible to search across all four major GGBN resources (data portal, registry, document library, and wiki). This, in particular, will facilitate the access to information on biobank management, Access and Benefit Sharing, tutorials as well as GGBN conference presentations (Figs 1, 2, 3).

In this presentation we shared information on the new GGBN Data Portal as well as how the GGBN stable identifiers are structured and their future potential use to enrich data in other infrastructures such as the European Nucleotide Archive (ENA).
Analysis of balancing solutions for simple assembly lines
Authors: El Machouti Sana , Hlyal Mustapha , Babay Amel , El Alami Jamila
Published: November 2024

Purpose: Assembly Line Balancing (ALB) is critical to manufacturing efficiency and productivity. It involves assigning tasks to workstations to optimise performance while satisfying task priority and cycle time constraints. The Simple ALBP (SALBP) is a simplified version of the general problem that has received considerable research interest. Many academic works have been published on this topic, using a variety of methods, including exact, heuristic, and metaheuristic approaches. Therefore, the purpose of this research is to present a comprehensive evaluation of the literature on the methods used to solve the SALBP.Design/methodology/approach: A comprehensive literature review was conducted to identify, select, analyse, and summarise 126 papers on SALBPs. The study started with the selection of relevant keywords. The selected papers were then narrowed down using various criteria.Findings: The analysis showed that SALBP-1 and SALBP-2 are the most common types, with metaheuristic approaches being the most widely used. Despite extensive research, there is a significant need for studies focusing on SALBPs for multi- and mixed-models, particularly in the context of U-shaped and two-sided lines.Originality/value: This literature review contributes to the identification of key areas for improvement in the SALBP and provides insight into potential directions for future research.
Hopf bifurcation and Turing pattern of a diffusive Rosenzweig-MacArthur model with fear factor
Authors: Zhang Jing , Fu Shengmao
Published: November 2024

In this paper, the dynamic behavior of a diffusive Rosenzweig-MacArthur (R-M) predator-prey model with hyperbolic tangent functional response and fear effect was investigated. For the local system, we gave a detailed classification of equilibria and performed bifurcation analysis. It was shown by numerical simulation that both the capture rate and fear factor have a stabilizing effect. Furthermore, the existence of limit cycles was discussed when the prey was in low fear or carrying capacity was sufficiently large. For the reaction-diffusion system, we considered the local stability of a unique positive equilibrium, Turing instability of both positive equilibrium and homogeneous periodic orbits under weak fear effect or strong carrying capacity, the direction of Hopf bifurcation and the stability of bifurcating periodic solutions under small fear cost and large diffusion coefficients, as well as the existence of positive nonconstant steady states. However, in the absence of fear effect, Turing instability of both positive equilibrium and homogeneous periodic orbits did not occur. Meanwhile, numerical examples were given to illustrate the corresponding analytic results.
Dans les cercles de Luis García Hevia à Bogota
Authors: Zalamea Patricia
Published: November 2024

Cet article se concentre sur l’œuvre du peintre et photographe colombien du xixe siècle, Luis García Hevia, dans le contexte du développement de la photographie dans la Colombie du milieu du siècle. Les premiers portraits au daguerréotype ont été réalisés en Colombie dans les années 1840 et 1850, dans le cadre d’un réseau international de peintres et de photographes qui coexistaient à Bogota, notamment après l’arrivée du baron Jean-Baptiste Louis Gros en tant que diplomate français en 1839 et l’association d’Hevia avec le photographe nord-américain Louis Armstrong Bennett. Ainsi, les premières tentatives photographiques de Hevia sont ici contextualisées et analysées en relation avec la manière dont il a, pour le portrait, expérimenté différents médias tout en s’appuyant sur des modèles classiques, bien avant la création de l’Académie colombienne des arts dans les années 1880.

Ces appareils, outils et articles photographiques circulaient, au tournant des xixe et xxe siècles, aussi bien dans les mains des professionnels de la photographie que des amateurs qui en expérimentaient l’usage. Ils traversaient également les frontières, en dessinant les contours d’un marché global en plein essor. C’est à ce monde matériel que s’intéresse cet article dans le cadre de l’Empire ottoman des années 1880 aux années 1920, dans une approche de l’histoire de la photographie par le prisme de la culture matérielle. On observe ainsi les réseaux d’exportation du matériel photographique, les coulisses de la production, une nouvelle conception de la consommation ainsi que le développement d’une communauté de photographes amateurs accompagnée de guides, publicités, catalogues, rayons des grands magasins, concours de photographies et photographies publiées dans les journaux illustrés.
Photographe / photographié

La photographie a dès son origine déterminé un cadre technique, pragmatique et esthétique dans lequel les relations humaines se sont trouvées infléchies. L’observation de différents cas de figure, depuis le protocole de la photographie posée à la chambre des années 1850 jusqu’aux rencontres plus intempestives permises par l’introduction des appareils instantanés à main dans les années 1890, permet d’esquisser une histoire interactionnelle de la prise de vue, de mettre en lumière l’asymétrie des rapports induits par la médiation photographique et d’interroger l’acculturation progressive des sociétés humaines à ce cadre relationnel asymétrique.
Présence de militaires ou fonctionnaires et de “Barbares” en Lyonnaise centrale et Aquitaine Nord-Est (fin IIIe-fin Ve siècle) : réalités et limites

On se propose d’examiner ici, d’un point de vue synthétique mais fondé sur des corpus de données aussi complets que possibles, la documentation mobilisable pour reconnaître la présence de populations exogènes barbares, d’une part, de membres de la militia (armée et administration) de l’autre ; ceci dans un vaste territoire couvrant le Centre et le Centre-Ouest de la Gaule, entre le dernier tiers du iiie s. et la fin du ve s. : sources textuelles, voire épigraphiques, et archéologiques (immobilières et mobilières).
Une nouvelle crémation du Bas-Empire au Nord de la civitas Carnutorum
Authors: Fourré Alix
Published: November 2024

Un diagnostic archéologique réalisé à la Fontaine-la-Guyon (28) a révélé une importante occupation antique constituée, notamment, d’un ensemble funéraire. Ce dernier se compose d’incinérations et au moins d’une inhumation. Toutes les incinérations sont datées du ier s. à l’exception d’une crémation. Celle-ci, isolée du secteur funéraire, présente un dépôt constitué de deux vases datés du Bas-Empire. La présence d’une incinération datée de l’Antiquité tardive est inédite dans ce secteur géographique où la pratique de l’inhumation a remplacé celle de l’incinération dans le courant du iiie s. ap. J.-C.

Incidence of chronic groin pain after Lichtenstein hernia repair at the  National Hospital Sri Lanka
Authors: Bandara Nimeshana , Senevirathne Sanjeewa
Published: November 2024

Background
Chronic inguinal pain is the most common complication following inguinal hernia repair and it affects patient quality of life. This study aimed to find its incidence and how severely it affects day-to-day life in the Sri Lankan population.
Methods
100 patients were recruited to the study on admission for inguinal hernia repair to the National Hospital Sri Lanka and follow-up regarding pain was done at 6 months over the phone. We surveyed the incidence of pain, the severity of pain during day-to-day activities and how activities are limited due to chronic groin pain.
Results
Out of 100 initial participants, 75 patients completed 6-month follow-up. From 75 patients, 31 (41.3%) patients had chronic groin pain. No patients had severe pain at rest and only one (1.3%) had severe pain either during home chores or workplace activities. Mild pain at rest was seen in 4 (5.3%) and mild pain, either during home activities or workplace activities, in 21 (28%) of participants. Moderate groin pain at rest, at home activities and at workplace activities was seen in two (2.7%). two (2.7%) and one (1.3%), respectively. Of 75 participants at 6 months, only one (1.3%) had restricted home activities, seldomly. But three (4%) had seldom restrictions on leisure/religious activities and one (1.3%) had occasional restrictions. One (1.3%) had always restrictions on workplace activities and four (5.3%) had seldom restrictions.
Conclusions
 
The incidence of chronic inguinal pain after inguinal hernia repair in our study is similar to that found in the literature. However, there is a marked reduction in the effect of pain on day-to-day activities in our study. Which may be due to less severity of pain, good pain tolerance or poor health-seeking behaviour. This needs further evaluation to find out the exact cause for less reporting of the severity of pain and to improve health-seeking behaviour.
Comparisons of apple cultivar suitability for Rhagoletis pomonella (Diptera: Tephritidae) from Washington State, United States of America
Authors: Yee Wee L.
Published: November 2024

It is unclear whether larval infestations of Rhagoletis pomonella (Walsh) (Diptera: Tephritidae) in earlier (softer) apple (Rosaceae) cultivars are greater than in later (firmer) apple cultivars in Washington State, United States of America, where flies were introduced and are quarantine pests of apple. Here, a field survey of apples in a noncommercial setting in Washington and experiments testing whether earlier apples are more suitable than later apples for Washington-origin R. pomonella were conducted. Early season ‘Gala’ and ‘Golden Delicious’, midseason ‘Red Delicious’, and late-season ‘Granny Smith’ and ‘Fuji’ were exposed to flies reared from early and midseason apples in laboratory experiments and to wild flies in apple trees in field experiments. The field survey provided evidence for softer apples being more infested and suitable. Likewise, most of the laboratory and field experimental data showed that ‘Gala’ and ‘Golden Delicious’, two of the softer apples tested, produced the most larvae and were most suitable, regardless of whether test apples were conventional or organic and ripe or unripe. To optimise fly trapping protocols in Washington, trapping in early apple trees near ‘Gala’ and ‘Golden Delicious’ orchards should be prioritised over trapping near mid- or late-season apple cultivar orchards.
Diagnostic performance of dual-energy CT with electron-density reconstruction for lumbar disc herniation

Published: November 2024

Background: Magnetic resonance imaging (MRI) is used for the evaluation of degenerative spinal disease. However, its utility is restricted in routine practice because of contraindications and a lack of widespread availability. Dual-energy computed tomography (DECT) is a newer technique for the evaluation of degenerative spinal disease.Objectives: This study aimed to evaluate the diagnostic performance of DECT with electron-density (ED) image reconstruction compared to standard CT for the detection of lumbar disc herniation, with MRI as the gold standard.Method: The retrospective study included 84 patients between 01 July 2023 to 31 December 2023 who underwent DECT and 1.5-T MRI within 1 week. Four radiologists, blinded to the clinical and MRI information, independently evaluated the standard CT series and DECT series with ED reconstructions for lumbar disc herniation and spinal nerve root impingement. The gold standard for comparison was lumbar spine MRI, and diagnostic accuracy was measured with sensitivity and specificity.Results: MRI revealed 417 lumbar disc herniations. Dual-energy computed tomography with ED reconstruction showed higher sensitivity (86.36% [532/616] vs. 57.79% [356/616]) and specificity (96.86% [1019/1052] vs. 95.82% [1008/1052]) for the detection of lumbar disc herniation compared to standard CT.Conclusion: Dual-energy computed tomography with ED reconstruction shows better diagnostic performance for the detection of lumbar disc herniation compared to standard CT and can be a useful alternative imaging modality when MRI is contraindicated or unavailable.Contribution: This study shows the usefulness of DECT as an alternative imaging technique for screening of degenerative spinal disease whenever MRI is contraindicated or unavailable.
On the Cahn–Hilliard equation with kinetic rate dependent dynamic boundary conditions and non-smooth potentials: Well-posedness and asymptotic limits
Authors: Lv Maoyin , Wu Hao
Published: November 2024

We analyze a class of Cahn–Hilliard equations with kinetic rate dependent dynamic boundary conditions that describe possible short-range interactions between the binary mixture and the solid boundary. In the presence of surface diffusion on the boundary, the initial boundary value problem can be viewed as a transmission problem consisting of Cahn–Hilliard-type equations both in the bulk and on the boundary. We first establish the existence, uniqueness, and continuous dependence of global weak solutions. In the construction of weak solutions, an explicit convergence rate in terms of the parameter for the Yosida approximation is obtained. Under some additional assumptions, we further prove the existence and uniqueness of global strong solutions. Next, we study the asymptotic limit as the coefficient of the boundary diffusion goes to zero and show that the limit problem with a forward-backward dynamic boundary condition is well posed in a suitable weak formulation. At last, we investigate the asymptotic limits as the kinetic rate tends to zero and infinity, respectively. Our results are valid for a general class of bulk and boundary potentials with double-well structure, including the physically relevant logarithmic potential and the non-smooth double obstacle potential.
Stability of a cross-diffusion system and approximation by repulsive random walks: A duality approach
Authors: Bansaye Vincent , Moussa Ayman , Muñoz-Hernández Felipe
Published: November 2024

We consider conservative cross-diffusion systems for two species where individual motion rates depend linearly on the local density of the other species. We develop duality estimates and obtain stability and approximation results. We first control the time evolution of the gap between two bounded solutions by means of its initial value. As a by-product, we obtain a uniqueness result for bounded solutions valid for any space dimension, under a non-perturbative smallness assumption. Using a discrete counterpart of our duality estimates, we prove the convergence of random walks with local repulsion in one-dimensional discrete space to cross-diffusion systems. More precisely, we prove quantitative estimates for the gap between the stochastic process and the cross-diffusion system. We first give rough but general estimates; then we use the duality approach to obtain fine estimates under less general conditions.
Spanning trees for many different numbers of leaves
Authors: Noguchi Kenta , Zamfirescu Carol T.
Published: November 2024

Let $G$ be a connected graph and $L(G)$ the set of all integers $k$ such that
$G$ contains a spanning tree with exactly $k$ leaves. We show that for a
connected graph $G$, the set $L(G)$ is contiguous. It follows from work of
Chen, Ren, and Shan that every connected and locally connected $n$-vertex graph
-- this includes triangulations -- has a spanning tree with at least $n/2 + 1$
leaves, so by a classic theorem of Whitney and our result, in any plane
$4$-connected $n$-vertex triangulation one can find for any integer $k$ which
is at least $2$ and at most $n/2 + 1$ a spanning tree with exactly $k$ leaves
(and each of these trees can be constructed in polynomial time). We also prove
that there exist infinitely many $n$ such that there is a plane $4$-connected
$n$-vertex triangulation containing a spanning tree with $2n/3$ leaves, but no
spanning tree with more than $2n/3$ leaves.

Animal manure has been used to manage soil fertility since the dawn of agriculture. Applying of this residual organic matter on agricultural soils can cause heavy metals accumulation, migration of pathogens to water sources, and food and generation of greenhouse gases. Biochar obtained through thermochemical conversion shows potential in agronomic uses. This study investigated the chemical composition and environmental risk of heavy metals in cattle manure and their biochar developed in the thermal range 700°C-850°C.
