100 års kamp for sociale rettigheder og global solidaritet
Authors: Estrup Jørgen
Published: January 2025

Problemstillingen ‘national egeninteresse’ contra ‘globalisering’ er langt fra ny. Den var afgørende for dannelsen af ILO ved afslutningen af 1. verdenskrig. Det gav sociale rettigheder og lige konkurrencevilkår via internationalt samarbejde og fælles regler. National egoisme skaber konflikter og undergraver det globale fællesskabs fordele.

Arbejdernes Børneblad var et lille revolutionært 14-dagsblad udgivetaf tre socialistiske børne- og ungdomsorganisationer. Fastforankret i solidaritet og klassefællesskab tog det kampen opmod de kristne og militaristiske børneblade på markedet. Dethenvendte sig til alle arbejderhjem, hvor der var børn. Redaktørernesambitioner var høje, og bevægelsens interesse for bladetovervældende, men det måtte snart gå ind. Artiklen handler omdriften af bladet, hvordan det præsenterede sig over for læserneog hvad det indeholdt af tekster og illustrationer.

Authors: Bjørnsson Iben
Published: January 2025

Dette er anden artikel ud af tre om Urban Hansen karrierevej i den Socialdemokratiske bevægelse. I hele ‘serien’ forfølges spørgsmålet om, hvad var det for et parti, der skabte politikeren og hvad der skulle til for at komme til tops i det. I denne artikel søges spørgsmålet besvaret ved at se på Urban Hansens tid i den københavnske fællesledelse og AIC. Fokus i tredje artikel vil være hans tid i Folketinget og borgerrepræsentationen indtil han blev socialborgmester.
Den communistiske Hovedmand Wilhelm Weitling og den tidlige arbejderbevægelse
Authors: Nygaard Bertel
Published: January 2025

Siden etableringen af massearbejderbevægelserne fra slutningen af 1800-tallet har man ofte betragtet de tidlige socialistiske retninger entensom historiske blindgyder eller – i bedste fald – som optakter til senere og mere ‘rigtige’ sociale bevægelser. i dag, efter svækkelsen af de sejrssikremodernistiske ideologier, herunder meget af den ofte alt for selvsikre‘videnskabelige’ socialisme, er det formentlig mere oplagt atbetragte de tidlige socialistiske strømninger som historiske fænomeneri egen ret.

Den 31. januar 1933 blev den politiske magt i Tyskland overdragetdet nazistiske parti (NSDAP). De dominerende samfundsgrupperfandt det åbenbart nødvendigt, hvis de skulleundgå et angreb på deres økonomiske interesser og var derfor villige til(midlertidigt) at overdrage den politiske magt til NSDAP. Som historienviser, fandt de politiske kræfter i Danmark den selvsamme dagen helt anden løsning på samfundets krise i form af et klassekompromis:Kanslergadeforliget og Socialreformen.Begivenhederne i Tyskland havde bl.a. til følge, at hvis det tyske socialdemokratis(SPD) partiarkiv skulle overleve, måtte det bringes i sikkerhed.En væsentlig del af dette arkiv bestod af Marx’ og Engels’efterladte papirer: Manuskripter, udkast og korrespondance.
Fortællinger om Pullmanstrejken, 1894
Authors: Friis Jan
Published: January 2025

Jan Friis: Tales about the Pullman Strike of 1894, Arbejderhistorie 2/2012, pp. 14-39.Once upon a time, not far from Chicago, Illinois, there was a model industrial town. The town was called Pullman City after its creatorand owner George Pullman. In Pullman City, the Pullman Palace Car Company (PPCC) con-trolled the church, schools, library, localmarket etc. Furthermore, PPCC’s propaganda machine endlessly published material about the city. Nearly all commentators were of the opinion that the relationship between capital and labor could be solved if everybody followed the example of Pullman. However, on the 11th of May 1894 the American Railway Union (ARU) went on strike against the PPCC. The rail traffic in America was ubsequently paralyzed.“NOT A WHEEL TURNS IN THE WEST” writes Chicago Times on the 28th of June 1894, and predicts “the biggest tie-up in all history”. In the end the strike was broken by federal troops; people were shot and the union leaders were arrested and jailed. This world  constantly changes and so do researchers’ theories and ideas. This insight leads to the desirability to create different accounts of history: The Pullman Strike can be understood as a revolt from spoiled and violent workers; a reaction to capitalistic oppression and exploitation; or a reaction – which transcends division of classes – to increased disciplination. In short, and with the help of metaphors, the article investigate the glasses through which a traditional historian perceive this world, followed by how a structural Marxist experiences it and in conclusion investigate the glasses through which a post-structuralist interprets it. To continue with metaphoriclanguage, each perspective should be understood as the design of different houses, the Pullman Strike works as the bricks and mortarthat holds each house together, I am the entrepreneur and you are the customer.
Socialdemokratiets invandrerpolitik

Heidi Vad Jønsson: The Social Democrat’s Integration Policy. Break-up and preliminary parlimentary playoff during Svend Auken’s chairmanship (1987-1992). Arbejderhistorie 2/2013, pp. 22-43.
Immigration and integration are two salient themes, which have proven to be highly problematic for the Danish Social DemocraticParty. This became evident, when the party lost the general election in 2001 to the Liberals, the Conservatives and the new pro-national, anti-immigration party, Danish People’s Party. One of the main explanations for the loss of power was irresolute and vaguepolitical statements, where internal debates and conflicts within the party dominated. The electoral consequences of these intraparty conflicts are clear, but it is, however, not so evident, why immigration and integration were such conflictual themes in the Social Democratic Party. The explanation is to be found within the party: an analysis of the development of an immigrant policy throughan intra-party policy development shows that these themes, immigration and integration, gave rise to a multidimensional conflict where both the problem definition, politicization, suggested solutions etc. were different depending on the level of governance (national or local). Even though there were attempts to coin integration as a Social Democratic solution to immigrants’ problems, the conflicts remained present also after the Social Democrats re-entered office in 1993. This article covers the period from 1987, when a new chairman was elected to 1992, where a Social Democratic parliamentary motion on better integration of immigrants was passed in Parliament. The previous period from 1979 to 1987 is covered in a previous article in Arbejdehistorie no 1, 2013.

Byplanlægning i Kaliningrad og udviklingen af en national sovjetisk identitet
Authors: Duberg Nielsen Eva
Published: January 2025

Eva Duberg Nielsen: Urban Planning in Kaliningrad – Developing National Soviet Identity. Arbejderhistorie 3/2012, pp. 19-32.The Kaliningrad region was not a part of the Soviet Union until 1945 where this Northern part of the former Eastern Prussia with itsmain city Königsberg was incorporated into the Soviet Union. The area was given military status and used by the Red Army as a sluice to transport former concentration camp prisoners, soldiers, and war material back to the Soviet Union. It was in this environment in acity, which had been reduced to ruins by British air raids in 1944, that a new Soviet city was to be formed not only physically but alsoideologically. In this article I analyze the ideological construction of Kaliningrad and what this meant for the citizens of the city. I examine which plans the rulers had for the future of Kaliningrad in the sense that the city was to be built ideologically correct and the population of the city given an identity as ideologically correct Soviet human beings. In the examination of Kaliningrad this process is showed through the execution of the plans to build and frame the city. In this process architecture played a key role and became a defining factor in the construction of an identity for the population in Kaliningrad. With time, however, these plans changed andso did the silhouette of the city from the neoclassicism of late-Stalinism to the squared functionality of the 1960’s and 1970’s. Forthe architects the overall ambition was to build a city for people to live in. With the change in political discourse in the post-Stalin years, they were able to express these visions in public which lead to many discussions between town architects, Soviet rulers, and the rulers of Kaliningrad. In this way the dynamic of a national Soviet identity developed in time, but in the end the city rulers took the decision to put forward the building up of a city, and an identity, that was distinguished Soviet without the traces of a Prussian past. Today Kaliningrad is an example of the general development of the Soviet Union and to this day the city is still left behind in the Soviet past as a symbol of the identity of the people that live at the uttermost Western border of the Russian Federation.

Revolutionen udskudt
Authors: Nygaard Bertel
Published: January 2025

Bertel Nygaard: Revolution postponed. Danish Trotskyists during the 1940’s, Arbejderhistorie 3/2012, pp. 77-94.Small groups of Trotskyists – dissident communists following the ideas of Leon Trotsky, the exiled Russian revolutionary – had existed in Denmark since German Trotskyist refugees arrived in Copenhagen following the Nazi takeover in 1933. During the Second World War and the German Occupation of Denmark, a core group of Danish Trotskyists advocated a strategy of mass-based resistance instead of the type of guerilla sabotage conducted by the main resistance movements. This strategy was premised on anticipations of a great wave of social revolution in the West as well as the USSR on the heels of the war. When this did not occur, the Danish Trotskyists were forced to revise their approach. In the process, a number of tiny networks of people, held together internally and differentiated from each other by personal as well as political considerations, expressed widely different anticipations for the Immediate future as well as a variety of political and organizational tactics considered necessary to the continuation of revolutionary politics in unrevolutionary circumstances. One network around Poul Moth, working to combine Trotskyism with the spread of Esperanto and the ‘anationalist’ ideas of the labour Esperantist movement, SAT, insisted on spiting circumstances by continuing mass agitation for revolutionary ideas. Another network, around Jacob Vedel-Petersen, was markedly pessimistic about the immediate future and revolutionary agitation, predicting the imminent rise of new forms of Fascism in Western Europe. These people opted for critical revisions of Marxist theory and analysis of contemporary society, in order to cope with such anticipations. A third, more heterogeneous network around Børge Trolle strove to continue their engagement in mass movements, but in forms adapted to circumstances characterized by the immediate impossibility of revolution. Despite a series of attempts at holding these factions together, even expanding them by short-lived attempts to establish a new communist party, Revolutionære Kommunister, they found it difficult to sustain collaboration when faced with extremely modest success. By late 1947, and, after some attempts at reviving their collaboration, the three groups had fallen apart, leaving only the group around Moth to continue Danish Trotskyism.

Antonio Palomino y la construcción de un programa iconográfico: significado y procedencia del concepto de idea
Authors: Giannotta Gaetano
Published: January 2025

Muchos estudios se han ocupado de desvelar mediante el método icono­gráfico el significado de la producción pictórica de Antonio Palomino (1655-1726), pero falta aún un análisis integral de la forma en que el pintor del rey construía sus imágenes y de cómo éstas actuaban en el observador. El presente artículo pretende abordar esta tarea desvelando el significado del concepto de idea, que es como Palomino se refería al proceso de invención y construcción de un programa iconográfico. Remitiéndonos al Museo pictórico y escala óptica y a la obra de ese artista, evidenciaremos, en primer lugar, su carácter a la vez especulativo y práctico. Esta doble naturaleza del concepto de idea nos llevará a profundizar en su origen y procedencia y, finalmente, en el modo en que Palomino lo absorbió.

Primary Antiphospholipid Syndrome Causing Critical Limb Ischemia and Ultimately Amputation in an Otherwise Healthy Young Female
Authors: Lyons Katherine , Adelman Ronald , Adelman Vanessa , Wenig Britney
Published: January 2025

This case report describes an otherwise healthy 43-year-old female who presented with severe pain, foot drop, and critical limb ischemia to her left foot caused by thrombosis of a peripheral artery secondary to antiphospholipid syndrome. Antiphospholipid syndrome is an autoimmune disease that frequently manifests as recurrent arterial and/or venous thrombotic events, ischemic strokes, and miscarriages. Antiphospholipid syndrome affecting primarily the arteries is less common as compared to venous thrombosis. Our patient underwent several vascular surgical interventions and anticoagulant treatment; despite this, she ultimately underwent a below-the-knee amputation due to worsening ischemia. The purpose of the current case report is to emphasize that antiphospholipid syndrome should be kept on the differential for arterial ischemic events such as critical limb ischemia without another known cause and should be managed with an interprofessional team approach.

Chronic inflammation via dysregulation of T cell immune responses is critically involved in the pathogenesis of atherosclerotic cardiovascular disease. Improving the balance between proinflammatory T cells and anti-inflammatory regulatory T cells (Tregs) may be an attractive approach for treating atherosclerosis. Although C-C chemokine receptor 4 (CCR4) has been shown to mediate the recruitment of T cells to inflamed tissues, its role in atherosclerosis is unclear. Here, we show that genetic deletion of CCR4 in hypercholesterolemic mice accelerates the development of early atherosclerotic lesions characterized by an inflammatory plaque phenotype. This was associated with the augmentation of proinflammatory T helper type 1 (Th1) cell responses in peripheral lymphoid tissues, para-aortic lymph nodes, and atherosclerotic aorta. Mechanistically, CCR4 deficiency in Tregs impaired their suppressive function and migration to the atherosclerotic aorta and augmented Th1 cell-mediated immune responses through defective regulation of dendritic cell function, which accelerated aortic inflammation and atherosclerotic lesion development. Thus, we revealed a previously unrecognized role for CCR4 in controlling the early stage of atherosclerosis via Treg-dependent regulation of proinflammatory T cell responses. Our data suggest that CCR4 is an important negative regulator of atherosclerosis.
Food intake enhances hippocampal sharp wave-ripples

Published: January 2025

Effective regulation of energy metabolism is critical for survival. Metabolic control involves various nuclei within the hypothalamus, which receive information about the body’s energy state and coordinate appropriate responses to maintain homeostasis, such as thermogenesis, pancreatic insulin secretion, and food-seeking behaviors. It has recently been found that the hippocampus, a brain region traditionally associated with memory and spatial navigation, is also involved in metabolic regulation. Specifically, hippocampal sharp wave ripples (SWRs), which are high-frequency neural oscillations supporting memory consolidation and foraging decisions, have been shown to influence peripheral glucose metabolism. However, whether SWRs are enhanced by recent feeding–when the need for glucose metabolism increases, and if so, whether feeding-dependent modulation of SWRs is communicated to other brain regions involved in metabolic regulation, remains unknown. To address these gaps, we recorded SWRs from the dorsal CA1 region of the hippocampus of mice during sleep sessions before and after consumption of meals of varying caloric values. We found that SWRs occurring during sleep are significantly enhanced following food intake, with the magnitude of enhancement being dependent on the caloric content of the meal. This pattern occurred under both food-deprived and
ad libitum
feeding conditions. Moreover, we demonstrate that GABAergic neurons in the lateral hypothalamus, which are known to regulate food intake, exhibit a robust SWR-triggered increase in activity. These findings identify the satiety state as a factor modulating SWRs and suggest that hippocampal-lateral hypothalamic communication is a potential mechanism by which SWRs could modulate peripheral metabolism and food intake.
Combining radio-telemetry and radar measurements to test optimal foraging in an aerial insectivore bird
Authors: Bloch Itai , Troupin David , Toledo Sivan , Nathan Ran , Sapir Nir
Published: January 2025

Optimal foraging theory posits that foragers adjust their movements based on prey abundance to optimize food intake. While extensively studied in terrestrial and marine environments, aerial foraging has remained relatively unexplored due to technological limitations. This study, uniquely combining BirdScan-MR1 radar and the Advanced Tracking and Localization of Animals in Real-Life Systems biotelemetry system, investigates the foraging dynamics of Little Swifts (Apus affinis) in response to insect movements over Israel’s Hula Valley. Insect movement traffic rate (MoTR) substantially varied across days, strongly influencing swift movement. On days with high MoTR, swifts exhibited reduced flight distance, increased colony visit rate, and earlier arrivals at the breeding colony, reflecting a dynamic response to prey availability. However, no significant effects were observed in total foraging duration, flight speed, or daily route length. Notably, as insect abundance increased, inter-individual distances decreased. These findings suggest that Little Swifts optimize their foraging behavior in relation to aerial insect abundance, likely influencing reproductive success and population dynamics. The integration of radar technology and biotelemetry systems provides a unique perspective on the interactions between aerial insectivores and their prey, contributing to a comprehensive understanding of optimal foraging strategies in diverse environments.

Published: January 2025

This study conducts a comparative analysis of the performance of ten novel and well-performing metaheuristic algorithms for parameter estimation of solar photovoltaic models. This optimization problem involves accurately identifying parameters that reflect the complex and nonlinear behaviours of photovoltaic cells affected by changing environmental conditions and material inconsistencies. This estimation is challenging due to computational complexity and the risk of optimization errors, which can hinder reliable performance predictions. The algorithms evaluated include the Crayfish Optimization Algorithm, the Golf Optimization Algorithm, the Coati Optimization Algorithm, the Crested Porcupine Optimizer, the Growth Optimizer, the Artificial Protozoa Optimizer, the Secretary Bird Optimization Algorithm, the Mother Optimization Algorithm, the Election Optimizer Algorithm, and the Technical and Vocational Education and Training-Based Optimizer. These algorithms are applied to solve four well-established photovoltaic models: the single-diode model, the double-diode model, the triple-diode model, and different photovoltaic module models. The study focuses on key performance metrics such as execution time, number of function evaluations, and solution optimality. The results reveal significant differences in the efficiency and accuracy of the algorithms, with some algorithms demonstrating superior performance in specific models. The Friedman test was utilized to rank the performance of the various algorithms, revealing the Growth Optimizer as the top performer across all the considered models. This optimizer achieved a root mean square error of 9.8602187789E−04 for the single-diode model, 9.8248487610E−04 for both the double-diode and triple-diode models and 1.2307306856E−02 for the photovoltaic module model. This consistent success indicates that the Growth Optimizer is a strong contender for future enhancements aimed at further boosting its efficiency and effectiveness. Its current performance suggests significant potential for improvement, making it a promising focus for ongoing development efforts. The findings contribute to the understanding of the applicability and performance of metaheuristic algorithms in renewable energy systems, providing valuable insights for optimizing photovoltaic models.
Safety profile of EZH2 inhibitors for cancer: a systematic review and meta-analysis
Authors: Zhao Zhou , Chen Xiufeng , Pang Huayang , Shi Yan , Sun Hao
Published: January 2025

Objective

To evaluate the safety profiles of EZH2-targeted inhibitors in cancer treatment, focusing on treatment-related adverse events (TRAEs) across various clinical trials.

Methods

We conducted a systematic review and meta-analysis using data from clinical trials involving EZH2 inhibitors reported up to May 31, 2024. Databases searched included PubMed, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), and ClinicalTrials.gov. Studies included were those involving patients treated with EZH2 inhibitors as monotherapy or in combination, specifically detailing the incidence of TRAEs. Data on all-grade TRAEs, grade 3 or higher TRAEs, and severe TRAEs were extracted and analyzed using random-effects models.

Results

Our systematic review and meta-analysis included 22 studies encompassing 1,002 patients who met the inclusion criteria. TRAEs were commonly observed during EZH2 inhibitor therapy, affecting 86% of patients (95% CI [79–94%]%; I2 = 89.5%). The incidence of grade 3 or higher TRAEs was 33% (95% CI [21–44%]; I2 = 93.5%), while severe TRAEs occurred in 15% of the cases (95% CI [9–22%]; I2 = 87.5%). The most frequently reported grade 3 or higher TRAEs in the pooled analysis were neutropenia (8%), thrombocytopenia (8%), and anemia (6%). Specifically, for tazemetostat, the most common grade 3 or higher TRAE was neutropenia (5%). For SHR2554, the most prevalent grade 3 or higher TRAEs were thrombocytopenia (17%), neutropenia (8%), and anemia (7%). Notably, treatment-related fatalities were rare, with only 0.9% of patients experiencing potentially fatal outcomes due to therapy.

Conclusion

EZH2 inhibitors demonstrate a manageable safety profile with a low incidence of severe TRAEs, emphasizing their potential as safe therapeutic options in cancer treatment. The low rate of severe TRAEs and the rare occurrences of treatment-related deaths support the continued clinical use and further investigation of EZH2 inhibitors.
Habitar un lugar reconstruido: la recuperación de los vínculos sociales de las personas mayores post-desastres socionaturales. Estudio del caso de Santa Olga a 7 años del incendio.
Authors:   , Chackiel Durán Camila Valentina
Published: January 2025

Esta investigación comprende cómo las personas mayores que experimentaron el incendio de 2017 en Santa Olga, Chile, han reconfigurado sus vínculos sociales, tanto informales –familia, amistades y vecinos– como formales –en el Club de Adulto Mayor y las iglesias– tras el proceso de reconstrucción. Se abordan brechas en la literatura de desastres, como la tendencia a homogeneizar la experiencia de las personas afectadas y la escasa consideración sobre cómo el desastre y la reconstrucción afectan los lazos sociales y el capital social. Desde un enfoque cualitativo utilizando entrevistas individuales, los hallazgos destacan que, aunque la reconstrucción física fue exitosa, la cotidianidad del envejecimiento en el lugar cambió debido a la reubicación de vecinos o familiares, la falta de reconstrucción de lugares clave como la plaza y sede del club, y los cambios materiales en las viviendas. Problemas de salud y movilidad propios de la vejez han limitado los esfuerzos para mantener vínculos sociales. Quienes permanecieron en Santa Olga reconfiguraron sus relaciones más fácilmente que las personas reubicadas en Renacer. A pesar de estos desafíos, han demostrado resiliencia, rearmando redes de apoyo, manteniendo vínculos importantes, adaptando espacios públicos y privados, y retomando su vida diaria tras el incendio y la pandemia. Este estudio contribuye a una comprensión amplia de la recuperación post-desastre, destacando la relevancia de elementos espaciales sobre los vínculos sociales y el buen envejecimiento. Se sugiere diseñar políticas públicas de reconstrucción que prioricen la reconstrucción de espacios clave para el desarrollo de los vínculos sociales de las personas mayores.

Sheet metal forming is the basic method of processing of deep-drawing quality steel sheets used in the automotive industry. A properly planned technological process of forming should include guidelines for friction conditions, or rather the coefficient of friction. Determination of the coefficient of friction is carried out using various methods. In this article, the strip drawing test was used to analyse the friction of low-carbon DC04 steel sheets. The tests were carried out at different contact pressures and with the use of different vegetable-oil based biolubricants. The most common edible and non-edible oils were selected for the tests: sunflower, rape-seed, moringa and karanja. The analysis of the experimental results was carried out using multilayer artificial neural networks (ANNs). Different learning algorithms and different transfer functions were considered in ANNs. Based on the analysis of experimental data, it was noticed that the coefficient of friction decreased with increasing contact pressure. The lowest values of the coefficient of friction, in the entire range of analysed pressures, were observed during lubrication with karanja oil. It was also found that Levenberg-Marquardt training algorithm with log-sigmoid transfer function provided the lowest values of performance errors and at the same time the highest value of the coefficient of determination R2 = 0.94719.

Published: January 2025

Background: This study explored the effects of Vitamin A supplementation on glucose tolerance among female undergraduate students at Ambrose Alli University, Ekpoma, adopting a comprehensive metabolic approach. Recent evidence has established that retinoid signaling pathways interact with glucose metabolism through nuclear receptor networks, particularly through Retinoid X Receptor (RXR) pathways, which regulate insulin sensitivity and glucose homeostasis. Objective: The primary goals were to assess the influence of Vitamin A supplementation on fasting blood glucose levels and to evaluate its impact on glucose tolerance test results, specifically through the oral glucose tolerance test (OGTT), based on the molecular understanding of retinoid-mediated metabolic regulation.
Method: The research involved conducting an OGTT on participants under two conditions: one without Vitamin A supplementation and another following a 100,000 IU dose of Vitamin A. Blood glucose levels were measured at six intervals (0, 30, 60, 90, 120, and 150 minutes) using an ACCU-CHEK Active glucometer, allowing for a detailed analysis of temporal glucose responses. Statistical analysis was carried out using a two-way ANOVA with GraphPad Prism 5 software to rigorously examine variations in glucose metabolism.
Result: The results revealed subtle but statistically significant fluctuations in blood glucose levels across different time points. However, the data indicated that Vitamin A supplementation had minimal direct effects on glucose tolerance. While the study was limited by its sample size and generalizability, it provides valuable baseline data on the metabolic responses of young female adults.
Conclusion: This research highlights the complex interplay between micronutrient supplementation and glucose metabolism. By investigating the effects of Vitamin A intake on glucose metabolism, the study addresses a critical gap in understanding the metabolic role of this essential micronutrient.

This study aims to investigate not only how learners perceive the effectiveness of this approach for long-term retention and practical application, but also how they experience the learning process in terms of cognitive load. Effectively managing cognitive load, the amount of information learners can process at once, is crucial for successful implementation of SR and SpR techniques. Building a strong vocabulary is essential for becoming fluent in a second language. Traditional methods like memorization often prove ineffective. Recent breakthroughs in understanding of memory and learning offer promising alternatives. such as spaced retention and spaced retrieval, believed to work even better together. The integration of SR and SpR positively influences the overall learning experience by promoting deeper cognitive engagement and better retention. Research shows that combining different instructional strategies, such as top-down and bottom-up processes, enhances vocabulary learning and retention. Cognitive load refers to the amount of information that learners can process at one time. While spaced learning offers advantages, it can be overwhelming if learners are presented with excessive vocabulary or complex retrieval tasks. As research on this combined approach continues to evolve, educators can utilize these findings to create inclusive and effective learning environments that empower L2 learners to achieve fluency and confidence in their vocabulary usage.

Currently, Sri Lanka is facing a major economic crisis. In the face of this economic crisis, it is clear that the government has failed to provide the necessary facilities for individuals to carry out their daily activities properly. It has become a challenge for the institutions as well as the industrial sector to carry out their work in an atomic manner through the daily electricity disruptions. Due to the inefficiency of electricity consumption in Sri Lanka, the amount of electricity wasted annually is very high. Therefore, the objective of this study was to find factors affecting electricity consumption in domestic applications in order to reduce the wastage of electricity. For achieving the objective, three cities of Colombo, Gampaha, and Rathnapura were selected using the cluster sampling method. Accordingly, the total sample was 75. A questionnaire and interview methods were used to collect data. Principal Component Analysis and Multiple Linear Regression Analysis were used for the data analysis. The findings revealed that the number of family members, the size of the house, the income, the use of Florence bulbs, living in a rented house, and the use of electrical appliances contribute to the increase in household electricity consumption. Considering those factors that are affecting domestic electricity consumption, the government, focusing on sustaining electricity consumption and providing necessary facilities to consumers, should take necessary steps.

This study aimed to assess important population bio-parameters of Synodontis schall in the Upper Atbara and the Setit dam complex (Sudan), comprising asymptotic length, growth curvature, length at maturity, optimum length, growth performance index, and mortality rate. The study was based on the need to assess capture fisheries; whose success depends on understanding the species' population structure. For five months (September 2019 and January 2020), 500 specimens of S. schall were collected randomly using gillnet from fishermen monthly. Morphometric parameters were taken in the field. The length-weight relationship demonstrated a strong correlation coefficient of r = 0.902, indicating a negative allometric growth pattern with a b-value of 2.619. The von Bertalanffy growth function was used in estimating population parameters obtained from length-frequency data; The asymptotic length (L∞) was 36.75 cm, the growth curvature (K) was 0.78 yr.-1, and the optimum length (Lopt) was 23.09 cm. The total mortality (Z) was 2.09 yr.-1; exploitation rate (E) = 0.34 yr. -1, natural mortality (M) and fishing mortality (F) = 1.39 and 0.7 yr. -1, respectively. The overall growth performance index of 3.023 indicated a slow rate of growth. The results suggest that this species and other commercial species require further research on population dynamics.

Lead acetate is arguably one of the environmental pollutants that threats the lives of living beings in multiple ways. Lead acetate occurs both naturally & due to human activities. Lead Acetate, a potential carcinogen, can enter the body through inhalation, ingestion, or dermal contact. Green tea and polyphenol have recently drawn attention of cell biologists. Multiple studies have confirmed the anti-inflammatory, anti-oxidative & anti-diabetic activities of polyphenols. In the Green tea extracts, Catechins including EGC (Epigallocatechin), ECG (Epicatechin-3-gallate), EGCG (Epigallocatechin-3-gallate) and EC (Epicatechin) are the major polyphenols which show a vast range of ameliorating effects on deleterious effects of different organs. Proper supplementation or dosage of green tea extracts may improve TAC (Total antioxidant capacity) and reduce the concentration of MDC (Malondialdehyde) in liver, brain and blood of vertebrates. Epicatechin supplementation could significantly lower the MDA levels and increase the glutathione concentration & catalase. It also increases superoxide dismutase (SODs, helpful antioxidant to defense against oxidative stress) & glutathione peroxidase activities in major organs. Though, high doses might have adverse effects, it has the capability to protect against oxidative damage & promote overall health.  Twenty mature albino rats were used, divided into four groups of five rats per group. Group 1 (control male) were not administered with lead acetate or green tea extract; it received water only. Group 2 (male) was given lead acetate solution 0.003 ml/g; Group 3 (female) was administered with lead acetate 0.003 ml/g and Group 4 (male) was treated with lead acetate (0.003 ml/g) followed by green tea extract (0.0002 ml/g) daily. This study investigated the effect of lead acetate intoxication and ameliorating upshot of green tea extract on some haematological, histological, cytogenetical factors of Albino Rats.

Aims: To study soil organic carbon content across different land use systems along four elevational gradients in the Himalayan Region of West Bengal.
Place and Duration of Study: Kalimpong and Darjeeling districts of West Bengal, India, between April to June 2019.
Methodology: Six major land use systems were selected spanning an altitudinal gradient of 400-500 m, 900-1000 m, 1400-1500 m, and 1900-2000 m, ensuring that each land use system was represented at every elevation. The land use systems included: 1. open cropland with rice, maize, winter vegetables, and pulses; 2. mandarin orchard; 3. large cardamom-based agroforestry under alder and Albizia species; 4. ginger-based agroforestry with mixed shade trees; 5. tea plantation under Albizia species; and 6. undisturbed forest.
Results: Undisturbed forests had the highest OC content (21.74 g kg-1), followed by tea plantations (19.28 g kg-1), large cardamom (17.86 g kg-1), ginger-based agroforestry (15.98 g kg-1) and mandarin orchard (13.94 g kg-1). While, open crop fields had the lowest OC content (10.92 g kg-1) across various elevational gradients. Soil organic carbon showed a positive correlation with elevation and a decrease with soil depth. At higher elevations, high soil moisture and relative humidity enhance the production of above- and below-ground biomass, increasing soil organic carbon content, while lower temperatures reduce microbial decomposition, further promoting organic carbon sequestration.
Conclusion: These findings provide crucial insights for researchers and policymakers, providing valuable information to assist in decision-making for sustainable land use management.
