Published: February 2025

Abstract
Infectious healthcare waste (iHCW), after microbial inactivation treatment, primarily ends up in landfills. Although the morphological composition of iHCW depends on the type of health facility, predominantly HCW consists of plastic and textile waste. Furthermore, after the treatment iHCW is cleaner from a microbiological contamination perspective than household waste, making it a highly valuable resource. Recycling iHCW has environmental and economic benefits and by valorising iHCW, it would be possible to reduce the amount of landfilled waste and use it as a resource. The aim of the research is to understand the environmental consequences and potential benefits of treated iHCW valorisation scenarios through the ‘gate-to-gate’ (from iHCW generation at medical facilities to end-of-life or recovery) life cycle assessment framework and to compare it with the existing practice – landfilling with functional unit 1 ton of treated iHCW and using ReCiPe 2016 (Midpoint, Hierarchist perspective) method. Valorisation scenarios (VS) analysed the use of treated HCW as a substitute of feedstock for reinforced asphalt, reinforced cement, RDF, syngas, acoustic panel and plastic components used for hydroponics. The results of the LCA demonstrate that from the environmental impact perspective, the best scenarios are syngas production (VS4) with cumulative result −11Pt and −237 kg CO2 eq for global warming impact category and RDF (VS3) with result −5Pt and −195 kg CO2 eq for global warming impact category, as the entire iHCW flow is recycled into energy. However, when recycling waste, the most valuable product must be created, and then the best results from plastic recycling are plastic components for hydroponics (VS6) with result 50Pt and 1181 kg CO2 eq for global warming impact category and reinforced asphalt (VS1) with result 53 Pt and 1246 kg CO2 eq for global warming impact category. From textile recycling acoustic panels (VS5) with result 55 Pt and 598 kg CO2 eq for global warming impact category and reinforced cement (VS2) with result 55 Pt and 603 kg CO2 eq for global warming impact category. Therefore, additional scenario was created where plastic, textile and residual iHCW streams are fully recycled and fully eliminating landfilling. The results show that BAU with result 75 Pt and 1509 kg CO2 eq for global warming impact category has the greatest environmental impact compared to any of the VS considered in this research. Of the total scenario impacts, the largest impact is caused by waste disposal, followed by transport, which has a similar impact in all scenarios due to assumptions about the distance to be transported, and iHCW treatment also has a similar impact in all scenarios, but the bigger difference is the environmental benefit from recycled waste. Based on the LCA results, recommendations for the stakeholders are developed.
Gender Bias in Succession in Family Companies: Theoretical Analysis With Application to a Portuguese Region
Authors: Tomé Eduardo , Campos José , Gromova Elizaveta 
Published: February 2025

Objective: In this paper we analyse the problematic of succession in family businesses, and we specifically address the situation of women within that process. The problem is important because, in one hand. family business are among the most prevalent in the economy, and because, in the other hand laws, and rules define gender equality as a very important social rule.

Method: We first make a literature review on the topic using the SCOPUS database, and after we detail the results of study made in the Portuguese region of Madeira Island

Results: We conclude that, rather surprisingly, women are discriminated in succession, and this reality has been described in theory and in same empirical studies, and is confirmed, sadly, in our study about Madeira Island.

Research Implications: The implications of these results should be great – it is of no use having all the laws published if they are not enforced and women are still harmed and discriminated in such an important social matter
he practical and theoretical implications of this research are discussed, providing insights into how the results can be applied or influence practices in the field of [insert field of study]. These implications could encompass [list impacted areas or sectors].

Originality/Value: The limitation of this study is that the sample we use in the study is small, but we would underline that the findings of our study are very much aligned with previous ideas. It seems that the old fashioned sexism so well described by Beauvoir in the middle of last century (Beauvoir, 1949) is still a fact. With those results we wonder if that sexism, culturally ignited and learnt as it, can be eliminated. Finally the paper is original because we first make a literature review and then present a case study that illustrates this theory.

Published: February 2025

Objective: Guidance & counselling is an enterprise used globally and in SA as a strategy to promote excellent academic performance of learners. Nevertheless, its effectiveness is not given enough attention regardless that some schools continue to underperform below the national set standards of perfomance. The purpose of this project study was to investigate, ‘The significant aspects of effective guidance and counselling that promote excellent academic achievement in rural Secondary Schools of Vhembe District, South Africa.

Theoretical Framework: This study was informed by the role of the teacher as a leader. According to Ma and Marion (2021) the teacher promotes academic achievement in South African rural schools. The guidance and counselling teacher in this role is seen as the catalyst for change, a visionary who is not content with the status quo and always looking for a better way of doing things. Guidance and counselling teachers serve the purpose of exposing different learning opportunities for learners in rural schools and fellow educators.

Method: Convergence design was used; mixed methods approach purposive sampling procedure was followed to select participants who were interviewed telephonically, and questionnaires were distributed physically to the respondents.

Results and Discussion: Results showed that Life Orientation teachers and curriculum advisors teachers (participants) agreed that guidance and counselling is an enterprise that promotes learners’ performance. The study concludes that if guidance and counselling is implemented effectively the performance of learners in rural areas will improve.

Research Implications: The study recommends that the department should promote the implementation of guidance and counselling by reviewing areas of guidance and counselling that need to be strengthened in rural areas.

Originality/Value: This study contributes to literature by highlighting the imperative aspects of guidance and counselling which promome excellent academic achievement.

Euterpe oleracea (naidí, murrapo o Açai) es una especie de palma que posee frutos oleaginosos con alto valor nutricional, su comercialización como pulpa constituye una fuente de ingreso económico para algunos pobladores en el sur del Pacífico colombiano. La pulpa contiene proteínas, minerales (calcio, magnesio, potasio, manganeso, cobre, níquel, boro, cromo) y vitaminas (B1, B6). Sin embargo, su aprovechamiento en el norte del Pacífico es limitado. Con la finalidad de conocer el estado de las poblaciones de esta especie en bosques inundables del Chocó, se estudió una población en el municipio de Quibdó desde octubre de 2022 hasta octubre de 2023. Se evaluó la biología floral, éxito reproductivo y eficiencia reproductiva (N=30 individuos). Se registró el número de raquilas por inflorescencias y la cantidad de flores masculinas y femeninas presentes en cada raquila, el éxito reproductivo se registró mediante la relación total de flores producidas por inflorescencias y la cantidad de frutos que se desarrollaron. El naidí es monoica con flores masculinas y femeninas en la misma inflorescencia, pero se desarrollan primero las masculinas (9-12 días) y luego las femeninas (9 días). Presenta flores en las raquilas en tríadas en la parte proximal y en díadas hacia la apical. La palma naidí produce entre 3±1 inflorescencias (1,4 ± 0,8 SD n=30). Su floración y fructificación se da durante todo el año. Cada inflorescencia produce 119,6 ± 19,27 SD (n=30) raquilas y con un total aproximado 1395,4 ± 241,7 SD (n=30) flores masculinas y 698,5 ±1207 SD (n=30) femeninas. Además, cada racimo produce en promedio 1287,7 ± 421,8 SD (n=30) frutos. Aquellos individuos con una mayor cantidad de flores también producen más frutos. Esta relación positiva presenta una gran variabilidad individual, con algunos individuos que exhiben un alto éxito reproductivo (60 %). En conjunto, la población evaluada tiene un alto éxito reproductivo promedio. Las palmas en la población mostraron una alta eficiencia reproductiva. La producción promedio fue de 1421,34 flores por inflorescencia con alto rendimiento de frutos (promedio de 1287,7 frutos). La tasa de abortos fue baja (entre 0,34 y 1,36), lo que indica que las palmas son eficientes en la producción de frutos. La notable alta significativa producción de frutos registrada, convierten al naidí de la localidad de estudio en un producto forestal no maderable con oportunidad para su aprovechamiento sostenible.
A correlation study of arterial stiffness with P300 event-related potential in non-haemodialytic and haemodialytic chronic kidney disease patients of renal origin

Introduction:
Chronic kidney disease (CKD) is associated with hypertension. The renal micro-vessels are vulnerable to the pulsatile nature of systemic pressure leading to arterial stiffness, which may lead to progressive renal disease besides other mechanisms. The stiffened cerebral vasculatures may also cause neural injury. Thus, cognitive impairment is prevalent in CKD patients. However, very few studies have attempted to examine the association of arterial stiffness with P300 event-related potential (P3ERP) in CKD patients of primary renal disease in the Indian population, which forms the basis of the study.

Materials and Methods:
Twenty-three age- and sex-matched non-haemodialytic and haemodialytic CKD patients were recruited in this cross-sectional and observational study. Montreal cognitive assessment questionnaire was applied to them to estimate global cognitive level. Peripheral and central blood pressure, augmentation index, brachial-ankle pulse wave velocity (baPWV), heart rate and P300 ERP were recorded. Biochemical analysis of the serum was also done. Appropriate statistical tests were performed to compare the differences between the variables of the two groups. Spearman’s Correlation test was performed to examine the relationship between vascular parameters and P300 ERP metrics.

Results:
Haemodialytic CKD patients exhibit early vascular ageing than non-haemodialytic CKD patients as evidenced by increased heart rate (P = 0.001) and higher central diastolic (P = 0.035) and peripheral diastolic blood pressure (P = 0.042). Although there was no significant difference in latency and amplitude of P300 ERP between the two groups, a significant positive association between baPWV and amplitude of P300 ERP was found. Moreover, higher serum phosphate (P = 0.021) and uric acid levels (P = 0.017) in haemodialytic patients promote vascular stiffening.

Conclusion:
It may be concluded that early vascular ageing in CKD patients occurs due to the interplay of multiple physiological factors, which finally perturb cerebral haemodynamics and are responsible for the cognitive impairment observed in these patients.

В работе представлены результаты численных расчетов распространения в акватории Охотского моря и проявления на его северном побережье в бухте Нагаева цунами от гипотетических очагов, расположенных вдоль тихоокеанского побережья Курильских островов. Выявлено, что в районе Тауйской губы, в которой расположена бухта Нагаева, происходит увеличение значений положительных амплитуд волн цунами от всех очагов по сравнению с окружающей акваторией. В бухте наибольшие значения высот волн отмечаются при расположении очагов цунами в районе ценртальных и южных Курильских островов. Анализ показал, что для северной части бухты Нагаева максимальные высоты заплесков волн цунами могут достигать 2,0 м, а скорости потоков - 1,6 м/с.
The paper presents the results of numerical calculations of the spread in the waters of the Sea of Okhotsk and the manifestation of a tsunami on its northern coast in Nagaev Bay from hypothetical foci located along the Pacific coast of the Kuril Islands. It was revealed that in the area of the Tauiskaya Bay, in which Nagaev Bay is located, there is an increase in the values of positive amplitudes of tsunami waves from all foci compared with the surrounding water area. In the bay, the highest values of wave heights are noted when tsunami foci are located in the area of the central and southern Kuril Islands. The analysis showed that for the northern part of Nagaev Bay, the maximum heights of tsunami wave surges can reach 2.0 m, andflow velocities - 1.6 m/s
ПРОСТРАНСТВЕННАЯ И ВРЕМЕННАЯ НЕОДНОРОДНОСТЬ СНЕЖНОГО ПОКРОВА В СМЕШАННОМ И ТЕМНОХВОЙНОМ ЛЕСУ И В ПОЛЕ

В работе рассмотрена изменчивость параметров снежного покрова в течение зимнего сезона в разных ландшафтах -смешанном лесу, поле и темнохвойном лесу на трех площадках, расположенных в окрестностях г. Южно-Сахалинск. В ходе наблюдений с периодичностью раз в неделю измеряли среднюю высоту снежного покрова, плотность по слоям, определяли структуру каждого слоя и средний диаметр кристаллов. По данным о плотности и высоте снежного покрова был рассчитан снегозапас. Установлено, что между параметрами снежного покрова в смешанном лесу, поле и темнохвойном лесу, нет четкой зависимости, позволяющей вывести коэффициенты для корректировки значений, определенных в одном типе ландшафта, для другого типа для малоизученных территорий. Разница в значениях различных параметров снежного покрова в лесу и поле заметно увеличивается в периоды оттепелей и метелей. Применение при расчетах для различных изысканий данных о снежном покрове, полученных на метеостанциях, расположенных даже на относительно небольшом расстоянии от исследуемой территории, приводит к значительным погрешностям. То же справедливо и для использования наблюдений, проводимых в разных ландшафтах даже на участках, расположенных на одной высоте и на небольшом удалении друг от друга.
The paper examines the variability of snow cover parameters during the winter season in different landscapes - mixed forest, field and dark coniferous forest at three sites located in the vicinity of Yuzhno-Sakhalinsk. During observations, the average height of snow cover, density by layers were measured once a week, the structure of each layer and the average diameter of crystals were determined. Based on the density and height of snow cover, snow reserve was calculated. It was found that there is no clear relationship between the parameters of snow cover in mixed forest, field and dark coniferous forest, which allows deriving coefficients for adjusting the values determined in one type of landscape for another type for poorly studied territories. The difference in the values of various parameters of snow cover in the forest and field increases significantly during thaws and snowstorms. The use of snow cover data obtained at meteorological stations located even at a relatively small distance from the study area in calculations for various surveys leads to significant errors. The same is true for the use of observations conducted in different landscapes, even in areas located at the same altitude and at a small distance from each other.
МОДЕЛЬ ОБОБЩЕННОГО ГАЗА
Authors: ФЕДОТОВ П В. 
Published: February 2025

Анализ применяемых в термодинамике уравнений и методов термодинамических расчетов показал, что в термодинамике используются два метода расчета энтропии газов: метод парциальных давлений (метод Дальтона) для смесей газов и метод парциальных объемов (метод Авогадро) для чистых газов. На основании этого показано, что причина появления парадокса Гиббса в методике расчетов энтропии для газовых смесей, в применении расчетов по закону Дальтона. При вычислении энтропии газовых смесей методом Авогадро, парадокс Гиббса исчезает. Анализ энтропии идеального газа показывает, что частицы идеального газа взаимодействуют друг с другом, предположительно посредством поля идеальных частиц. Анализ применения модели идеального газа на практике показывает, что в настоящее время данная модель применяется нелегитимно, в условиях, когда давление газов не предполагает обязательное требование малых плотностей, заложенного в постулатах модели идеального газа. Для исправления ситуации предложена модель обобщенного газа, постулаты которой распространены на любые давления (плотности) газов, с условием использования уравнений идеального газа, с учетом потенциального взаимодействия частиц идеального газа.
An analysis of the equations and methods of thermodynamic calculations used in thermodynamics showed that two methods of calculating the entropy of gases are used in thermodynamics: the method ofpartial pressures (Dalton's method) for gas mixtures and the method of partial volumes (Avogadro's method) for pure gases. Based on this, it is shown that the reason for the appearance of the Gibbs paradox in the method of calculating entropy for gas mixtures is in the application of calculations according to Dalton's law. When calculating the entropy of gas mixtures using the Avogadro method, the Gibbs paradox disappears. An analysis of the application of the ideal gas model in practice shows that this model is currently used illegitimately, in conditions where the gas pressure does not imply the mandatory requirement of low densities, laid down in the postulates of the ideal gas model. To correct the situation, a generalized gas model is proposed, the postulates of which are extended to any pressure (density) of gases, with the condition of using the equations of an ideal gas, taking into account the potential interaction ofparticles of an ideal gas.

Indonesian language learning at the elementary school level faces challenges in engaging students and improving learning outcomes. This study aims to enhance Indonesian language learning outcomes in fourth-grade students at SD Lafau Fadorozai through the implementation of the STAD (Student Teams-Achievement Divisions) cooperative learning model. The study adopts a Classroom Action Research (CAR) design involving a single class as the research subject. Data were collected through observations, learning outcome tests, and questionnaires on student response. The implementation of the STAD cooperative learning model was conducted two cycles, focusing on Indonesian language learning. The research results indicate a significant improvement in students' learning outcomes with average score after the application of the STAD model, as evidenced by an increase in The average post-test score (Mean = X) was significantly higher than the average pre-test score (Mean = Y), with a significant difference (p < 0.05) on learning outcome tests and positive student responses toward cooperative learning. The pre-test score was 63.47 and the post-test 66.53 the increase was 4.82%. These findings suggest that the STAD cooperative learning model is an effective strategy for improving Indonesian language learning outcomes at the elementary school level. This study underscores the importance of cooperative learning models in enhancing the quality of Indonesian language education at the elementary school level.
Discourse Markers in the Introductory Section of Research Articles in National accredited Journal

Published: February 2025

Discourse markers provide writers with signaling devices to connect ideas and guide readers in grasping the connection of ideas in the texts. An introductory section of a journal article represents a unique text which should be written with clear and interconnected arguments. This paper aims to reveal how discourse markers play vital roles in realizing the development of the arguments in this knotty text. To achieve this, introductory sections of articles published in a nationally accredited journal were examined. Using Fraser's (2009) functional classes of discourse markers, 22 introduction sections were analyzed employing text analysis to determine the usage of these markers. It was found that despite employing all types of discourse markers, not all of them were applied appropriately. Their uses may not be in line with their functional classification. Among others, there are three functional classes of discourse markers proposed by Fraser (2009), they are contrastive markers, elaborative markers, and inferential markers. Elaborative markers were the most used type among the different types, followed by contrastive and inferential markers. This implies that authors tended to develop ideas more often, whereas contrastive and inferential markers were used less frequently but were crucial for indicating differences and making conclusions within the texts.
