Published: December 2024

Background: Leishmania donovani can cause a serious infection if it is left without treatment. The parasite is transmitted by the bite of an infected female phlebotomine sandfly. The disease is prevalent throughout the world and in at least 88 countries. Objective: This study aims to know the effect of contraceptive pills (OC) on the severity of infection of Leishmania donovani in infected mice, by measuring the levels of the hormones estrogen and progesterone, cholesterol, and total protein in the sera of infected mice. It is taken by dosage in the form of tablets dissolved in water at a dose of 0.012 ml/day and is compared with the drug pentostam, which is given by injection at 0.04 ml/day for a treatment of 21 days. Methods: The animals were divided into five groups, only the first group was uninfected, while the remaining four groups were infected, as follows: The second group was infected only. It was not dosed with pills and was not injected with pentostam treatment., the third group was dosed orally with contraceptive pills, the fourth group was considered a treatment group (pentostam ), and the fifth group was dosed orally with pills and injected with treatment for comparison. Blood was collected from mice after three weeks on the 7, 14, and 21 days in special tubes containing a gelatinous substance for the purpose of conducting the required tests. Results: The results showed that the OC led to a significant increase in all indicators in the third week, which is compared with the drug group pentostam group, Data expressed as mean ± SD and values of ( P>0.05) were considered statically nonsignificant, while (P<0.05) and (P<0.01) were considered significantly different, highly significantly different, respectively. Conclusions: It can be concluded that OC pills had an important role in increasing the severity of parasite infection in laboratory animals through the noticeable increase in the indicators that were measured.

Authors: Abed Abdulrazzaq T. , Al-Rawi Ekhlass S.
Published: December 2024

Background: In many studies, spectral methods based on one of the orthogonal polynomials and weighted residual methods (WRMs) have been used to convert the variable-order fractional differential equation (VO-FDEs) into a system of linear or nonlinear algebraic equations, and then solve this system to obtain the approximate solution. Objective: In this paper, a numerical method is presented for solving VO-FDEs. The proposed method is based on Chelyshkov polynomials (CPs). Methods: WRMs are used to obtain approximate solutions of the governing differential equations. In addition, a new weight function based on Mittag-Leffler functions is proposed. The proposed method is applied to a group of linear and non-linear examples with initial and boundary conditions. Results: Acceptable results are obtained in most of the examples. In addition, the effect of polynomials (such as Chebyshev, Jacobi, Legendre, Gegenbauer, Hermite, Taylor, Mittag-Leffler, and Bernstein polynomials) on the accuracy of the approximate solution is studied, and their effect was found to be minimal in most tests. The effect of the proposed weight function is also studied in comparison with the weight functions presented in WRMs, and it was found that it has a strong effect in most examples. Conclusions: The results obtained indicate that the proposed method is effective for solving equations of variable order.

Published: December 2024

Background: Gastric cancer ranks as the 5th most common cancer worldwide and is the 3rd leading cause of cancer deaths,
responsible for approximately 783,000 deaths annually. In Uganda, its incidence has risen from 0.8 per 100,000 people in
1960 to 9 per 100,000 in 2014. Although vascular endothelial growth factor (VEGF) protein expression is critical for gastric
cancer management, its prevalence in Ugandan patients is unknown.
Objective: This study aimed to determine the prevalence of VEGF protein expression in gastric cancer and investigate related
clinicopathological features at the Makerere University Pathology Department.
Methods: A cross-sectional study was performed using conveniently sampled archived tissue blocks from patients diagnosed
with gastric adenocarcinoma. These samples underwent Hematoxylin and Eosin (H&E) and immunohistochemistry (IHC)
staining.
Results: The study analyzed 100 specimens with a male to female ratio of 1.56:1 and an average age of 59.4 years. VEGF
expression was positive in 57.0% of cases. The intestinal Lauren subtype constituted 79% of cases, while the diffuse
subtype made up 21%. The predominant histological subtype was tubular adenocarcinoma (52.0%). Most cases were
poorly differentiated (42.0%), well-differentiated (31.0%), and moderately differentiated (27.0%). Higher VEGF expression
was observed in lower tumor grades (71.0%) (p=0.059). Tubular adenocarcinomas exhibited the highest VEGF expression
(p=0.099). Male patients showed higher VEGF expression (P=0.610). Mucinous adenocarcinoma had the lowest VEGF
expression (p=0.004), and poorly differentiated adenocarcinomas also had very low VEGF expression (p=0.049).
Conclusion: The study revealed significant overexpression of VEGF in gastric adenocarcinoma tissues, with varying
associations to different clinicopathological variables.

that an animal market in Wuhan, China very likely is
the source of the SARS-CoV-2-virus and its consequent
transmission to humans [1]. Geographical clustering of the
earliest known COVID-19 cases and the proximity of positive
environmental samples to live-animal vendors suggests that

Published: December 2024

Understanding students' perceptions of socio-scientific issues (SSI), particularly in the context of biology, is essential for developing effective teaching strategies. This study analyzes students’ perceptions of SSI in biology, involving 360 participants from 10th- and 11th-grade classes at a high school in Majalengka, West Java, Indonesia. The participants, aged 16 to 17 years, were equally divided between the two grade levels. Data were collected using a 24-item survey questionnaire based on a five-point Likert scale. The results show an overall mean perception score of 3.31, indicating that students generally hold a neutral perception of SSI in biology. A weak correlation was observed between students’ overall perceptions and SSI in biology, with a p-value of 0.08 and an r-value of 0.02. Further analysis revealed minor differences in perceptions based on grade level and gender, with 10th-grade students scoring an average of 3.30 and 11th-grade students scoring 3.32. Male students averaged 3.28, while female students averaged 3.34. These findings suggest that although students exhibit neutral perceptions of SSI in biology, many struggle to connect biological concepts to real-life contexts. This highlights the need for further research to identify factors influencing students’ perceptions and to explore alternative learning models for improving understanding and engagement with SSI in biology.

Published: December 2024

The goal of this study was to reduce students' alternative conceptions (misconceptions) of action-reaction forces through the use of e-rebuttal texts. A mixed-methods approach, incorporating both quantitative and qualitative methods, was employed. The participants included 31 tenth-grade students (15 boys and 16 girls, aged 15-16 years) from a public high school in Sukabumi, West Java, Indonesia. The instrument utilized was a four-tier test consisting of 9 questions related to action-reaction forces: 3 verbal questions for the pre-test, 3 mathematical questions for the post-test (administered after learning), and 3 pictorial questions for the delayed post-test (administered over time). Data were analyzed based on categories of conception and correction of conceptions. The results indicated positive changes from the pre-test to the post-test, which remained consistent in the delayed post-test. The most significant rate of correction in students' conceptions from the pre-test to the post-test was observed in the Acceptable Change (ACh) category, while the highest percentage of changes from the post-test to the delayed post-test occurred in the No Change (NCh) category. It was concluded that e-rebuttal texts effectively reduce students' alternative conceptions (misconceptions) of action-reaction forces both immediately after learning and over time. Future researchers may consider utilizing learning models or strategies that involve group discussions to further facilitate the learning process.

Published: December 2024

This study aims to explore the development of understanding of the concepts of pH, acid-base titration, and buffer solutions among 11th-grade students and 2nd- and 4th-semester university students in chemistry education. It employs a cross-sectional design using open-ended questions and interview guidelines to collect data from 153 11th-grade students, 30 second-semester university students, and 40 fourth-semester university students. The open-ended questionnaire consists of 9 items (2 questions on the pH of solutions, 4 questions on acid-base indicators and titration, and 3 questions on buffer solutions and salt hydrolysis) on a continuous scale, with an Aiken's kappa validity of 0.61 (substantial agreement) and a Cronbach's Alpha reliability (KR-20) of 0.75 (acceptable). The results indicate that scientific understanding of pH concepts, such as the pH of solutions, acid-base titration, and buffer solutions, improves with education. However, comprehension of complex concepts remains low. The study's implications highlight the need for curriculum development and the selection and implementation of learning strategies that enable students to learn in a structured, gradual, and coherent manner. Curriculum development should map out subject matter, distinguish essential from non-essential content, and organize material from simple and essential topics to more complex and non-essential ones.

Published: December 2024

In the context of the Fourth Industrial Revolution, equipping students with critical and creative thinking skills within the framework of Education for Sustainable Development is essential but remains insufficiently explored, particularly in relation to nutrition concepts. This study evaluates the critical and creative thinking skills of eighth-grade students at a private junior high school and examines the relationship between these skills in the context of Education for Sustainable Development and nutrition. A total of 62 students participated in the study, which employed a correlational design to analyze data from a written test comprising fifteen multiple-choice questions on critical thinking and eight essay questions on creative thinking. To minimize guessing, the critical thinking test included well-designed distractors. Descriptive analysis was followed by the application of the Spearman test to determine the correlation between critical and creative thinking skills. The results indicated low performance in both areas, with average scores of 31.61 for critical thinking and 43.34 for creative thinking. Furthermore, no significant correlation was found between the two skills, as the significance value of 0.126 exceeded the threshold of 0.05. The findings suggest that systematic planning and continuous learning are necessary to enhance these skills and improve academic performance. The study emphasizes the need for structured educational strategies to develop critical and creative thinking concurrently, thereby informing curriculum development to support Education for Sustainable Development goals and prepare students to address future sustainability challenges.

Authors: Burzyńska A.
Published: December 2024

The concept of 'Industry 4.0' has introduced great dynamism into production environments, making them more integrated, connected and capable of generating large volumes of data. The digital transformation of traditional companies into innovative smart factories is made possible by the potential of Artificial Intelligence (AI), which is able to perform predictive analytics inspired by the development of Industrial Internet of Things (IoT) technologies or to support highly complex decision-making, in the era of zero-defect manufacturing. The need for innovative techniques and automated decision-making in diagnosing the causes of casting defects is increasing due to the growing complexity and higher level of automation of industrial systems. Particularly important are fully data-driven predictive approaches that enable the discovery of hidden factors influencing defects in castings and the prediction of the specific time of occurrence by analyzing historical or real-time measurement data. In this context, the main objective of this article is to provide a systematic overview of data-driven decision support systems that have been developed to diagnose the causes of casting defects. In addition, different methods for predicting casting defects are presented. Finally, current research trends and expectations for future challenges in the field are highlighted. It is hoped that this review will serve as a reference source for researchers working in the field of innovative casting defect prediction and cause diagnosis.

Authors: Ganesan Thenmozhi , Vanaraj Chandra , Subramanian Manoharan , Alagesan Radhika
Published: December 2024

The core concept in this paper is to hybridize a conventional engine-powered two-wheeler into a hybrid electric vehicle. The shift in the consumers' mindset from conventional IC Engine vehicles to Electric/hybrid vehicles may be a challenge due to the high initial investment. Hence, as a preliminary work, it is proposed to convert an IC engine vehicle to a hybrid electric vehicle considering factors such as affordability, user control, and flexibility. To make the hybrid vehicle available at an affordable price, lead-acid batteries are used for the study. Also, the BLDC motor used in this vehicle has been designed and developed according to the available design constraints. The moped has been redesigned to operate in either engine or electric mode individually depending on the rider’s desire and can switch over to any mode at any time as intended. This is achieved using a unique switching mechanism constructed using needle roller bearings. The concept of hybridization thus results in reduced emissions, especially in stop-go traffic where electric mode can be used, and the performance of hybrid electric vehicles is estimated.

Composite materials are defined as new materials formed by combining two or more materials that do not mix with each other, leveraging the best properties of each constituent. Composite materials are used in important industrial sectors such as aerospace and automotive due to their superior properties. In this study, XPS (extruded polystyrene) polymer foam was utilized as the core material. Glass fibers were combined with resin in a total of 8 and 12 layers, applied to both the top and bottom of the core structure. Production involved both manual laying and vacuum bagging methods. Two types of glass fiber, weighing 200 g/m2 and 300 g/m2 , were employed. After production, the composites were cut to standardized dimensions, followed by three-point bending and low-speed impact tests. Impact experiments were conducted with a constant energy of 50 J. Results showed that the 200 g/m2 glass fiber composites experienced perforation in the 8-layer samples and rebound in the 12-layer samples. Although greater deformation was observed in the impact tests of the 300 g/m2 glass fiber composites in the 8-layer samples compared to the 12-layer samples, rebound occurred in both. In three-point bending tests, the bending strength increased as the number of layers increased, and at the same number of layers, composites with 300 g/m² properties showed higher strength than 200 g/m² composites.

Published: December 2024

The Syr Darya River’s lower reaches of floodplain geosystems face growing environmental pressures, necessitating a thorough understanding of their vulnerability on which this study focuses, emphasising the role of natural and climatic factors. The research analyses the correlations and impacts of elevation, soil density, precipitation, air temperature, and normalised difference vegetation index (NDVI) on environmental vulnerability. The results indicate a strong positive correlation between elevation, precipitation, air temperature, and environmental vulnerability, with NDVI also playing a significant role. The study employs principal components analysis to further explore these relationships and generates an integrated vulnerability map, highlighting vulnerable areas, particularly near Kyzylorda city. The map also aligns with different land cover types, emphasising the dominant influence of environmental and climatic factors, especially maximum air temperature, precipitation, and elevation, on environmental vulnerability. The research concludes that the integrated vulnerability map serves as a valuable tool for guiding environmental management and conservation strategies, enabling targeted interventions and sustainable practices in areas of high vulnerability. The study’s methodology and findings offer crucial insights for effective environmental management and conservation in floodplain geosystems, promoting informed decision-making for sustainable development in the region.
The Logic of Sociability in the Scottish Enlightenment: Thomas Reid’s Social Operations of Mind1
Authors: Ivana Dragoş
Published: December 2024

This article sheds light on the logic of sociability in the Scottish Enlightenment, which has been regarded as a characteristic mode of thought and action, given the authoritative influence of David Hume’s “Science of Man” (1739). Hume’s “Science” focuses on the interaction between the moral self and other fellow beings able to display feelings of sympathy and thus to participate in the moral good and wellbeing of civil society. Hume’s influential argument left a legacy to other Scottish Enlightenment philosophers, among them being Thomas Reid, one of his well-known opponents, who was the first to coin and discuss “the social operations of mind.” The article seeks to provide an overall epistemological account of “social operations,” with particular focus on the act of promising and testimony. Opposed to “solitary operations” (cf. Reid), “social operations” become successful if and only if their expression by words or signs elicits the addressee’s reaction understood as the latter’s choice to accept it or not. In the case of testimony, I will show how Reid’s argument – sometimes paradoxical or contradictory – cannot get rid of judgement or reasoning when it comes to checking the veracity of what is testified, on the one hand, and of what is to be believed, on the other.
Flotsam and Jetsam: Art, Allegory, and Shipwreck in the Twenty-First Century (III)
Authors: Howard David Brian
Published: December 2024

This allegorical postcard is organized around two groups of photographs. The first group was the result of a joint collaboration with the Vancouver artist Scott Saunders, and it produced photographs which have peppered several of my previous texts published by American, British and Canadian Studies. The second is a series of photographs taken by Scott Saunders from the window of his apartment in Vancouver, in which he documents the street life constantly ebbing and flowing on the sidewalk below. The catalyst for bringing these two groups together was a photograph I took several years ago in Sambro, Nova Scotia (a small fishing village located just outside of the city of Halifax), depicting a forlorn sunken fishing vessel. The term “flotsam” is applied, according to the Oxford Reference Dictionary, to “the wreckage of a ship or its cargo floating on or washed up by the sea,” while “jetsam” describes the things or objects deliberately “thrown away, especially from a ship at sea and that float toward land.” Combined, these images of words and devastated human beings are caught in an apparently endless circulation of violence and contingency located at the heart of the urban fabric of a modernity bereft of any horizon of hope, redemption, or rescue.
Biomechanical effect of en-masse versus substep extraction space closure on posterior teeth using clear aligners: a finite element study
Authors: Jiang Yiru , Mei Li , Xu Li , Wang Jue , Feng Xiaoxia , Chen Xiaoyan
Published: December 2024

Objective

To evaluate the biomechanical effects of en-masse versus substep extraction space closure on posterior teeth during clear aligner treatment and to provide guidelines for optimising anti-tipping designs.

Methods

Twenty-four maxillary finite element models incorporating first premolar extractions treated by clear aligners were constructed. The models were divided into two groups: en-masse closure (I0, en-masse retraction; II0, en-masse mesialisation), and substep closure (Ia, canine distalisation; Ib, incisor retraction; IIa, premolar mesialisation; IIb, molar mesialisation). Within each group, different anti-tipping designs (1°, 2°, 3°) were applied to the posterior teeth.

Results

Compared to I0, groups Ia, Ib, and Ia+b exhibited less crown mesial displacement, root distal displacement, and mesial tipping of the posterior teeth. In contrast, groups IIa, IIb, and IIa+b demonstrated more crown mesial displacement, root distal displacement, and mesial tipping. Of note, IIa increased the mesial movement of the premolars and generated a distal force on the molars, mitigating their mesial inclination. IIb had a similar effect. Consequently, Ia, Ib, and Ia+b required significantly less anti-tipping design to maintain the pretreatment mesiodistal angulation of the posterior teeth. Conversely, IIa, IIb, and IIa+b necessitated more anti-tipping design to achieve bodily movement of the posterior teeth.

Conclusion

Substep retraction may reduce the mesial tipping and anti-tipping design of the posterior teeth. Substep mesialisation, however, may increase crown displacement, posterior mesial tipping, and the anti-tipping design; nevertheless, the reaction forces from adjacent teeth can partially alleviate these effects. Further clinical validation is necessary to confirm these findings.
PLS-PM Model for Sustainable Development of Ecotourism: Case Study of Ulytau Nature Park
Authors: Seidualin Darken A. , Mussina Kamshat P. , Mukanov Aidar H.
Published: December 2024

This article is devoted to a comprehensive study of the factors influencing the development of ecotourism in the Ulytau Nature Park, Kazakhstan. The authors use an integrated methodology that combines quantitative (statistical analysis) and qualitative (Analytic Hierarchy Process, survey of the local population) methods of analysis. The purpose of the study is to develop a model that allows predicting the development of ecotourism and justifying strategic decisions for its sustainable development.

As a result of the survey, 8 key factors affecting the development of ecotourism were identified: perceived environmental sustainability, perceived social cost, perceived economic benefits, maximizing community participation, long-term planning, community-centered economy, sense of place, and support for tourism development. Both subjective estimates (Analytic Hierarchy Process) and objective statistical data were used to determine the weights of these factors. Comparative analysis revealed discrepancies between subjective assessments and objective indicators, especially in the perception of the region’s image.

The main result of the study is the development of a qualitative model that uses logistic regression to assess the impact of factors on the development of ecotourism. This model, which considers both subjective and objective data, allows to simulate various scenarios and predict the development of the industry. The results obtained make it possible to identify priority areas for the development of ecotourism in Ulytau and develop recommendations for the creation of a sustainable and socio-economically effective model for the development of ecotourism both for Ulytau and for other regions with similar conditions. The article contributes to the existing body of knowledge on sustainable tourism development by offering a multidimensional data-driven approach that goes beyond theoretical discussions.
Televising the Space Race in Francoist Spain: Sebastià Estradé and the “Friends of Outer Space” (1967-1969)
Authors: Gorostiza Santiago
Published: December 2024

In the context of the space race, space science became an area of collaboration between the Spanish dictatorship and the United States of America during the 1960s. The Francoist regime leveraged its collaboration in the space race as an internal tool for political legitimization. This article examines the role of science popularization in this legitimization process by focusing on the TV show Amigos del Espacio (“Friends of Outer Space”), broadcast between 1967 and 1969 and aimed at young audiences. Specifically, it analyses the available episodes of the show and the trajectory of its scriptwriter, science writer and PhD in Law Sebastià Estradé (1923-2016). The article examines three key dimensions of Amigos del Espacio: the celebration of Spanish science and technology; the portrayal of the relationship between Spain and the United States; and the program’s integration of Catholic faith with the popularization of space science.
