Effect of pulverized leaves of Ocimum gratissimum (scent leaf) and Pterocarpus santalinoides (utrukpa leaf) on liver function enzymes of indomethacin-induced ulcerated adult male Wistar rats
Full text linkThis study investigated the effect of pulverized leaves of Ocimum gratissimum (scent leaf) and Pterocarpus santalinoides (utrukpa leaf) on the liver function enzymes activities of indomethacin-induced adult male Wistar rats. Fresh leaves of the samples were harvested, weighed and washed with tap water. One hundred grams of each leaf was blended with 200 ml of water to produce the pulverized samples used for the rat study. The results of the acute toxicity (LD50) test of the two leaf samples showed that the leaves were safe at high doses. Forty-nine adult male rats used for the study were grouped into 7 (A-G) based on body weight. The groups B-G were induced with 30 mg/kg/body weight of indomethacin after a 3-day acclimatization. Two rats were randomly selected from each induced group and sacrificed to ascertain the presence of ulcer. The group A which was not induced served as the control; the Group B was the negative control (induced but not treated);Group C the positive (induced and treated with standard drugs); the Groups D and E were treated with 300 and 600 mg/kg/body weight of pulverized Ocimum gratissimum sample, respectively while the Groups F and G were treated with 300 and 600 mg/kg/body weight of pulverized Pterocarpus santalinoides sample, respectively. All the groups were fed rat chow and water for 14 days. Liver function enzyme activities of the rats were analyzed using standard methods for baseline and endline. Data collected were statistically analyzed using the statistical product for service solution (SPSS) version 24.0. T-test was used to compare the baseline and endline data within the groups. Analysis of variance and Duncan’s new multiple range test were used to separate the means. The results were presented as means and standard deviation and a significant level was set at p<0.05. The leaf samples significantly (p<0.05) reduced the liver enzymes (ALT, AST and ALP) of the treated rats. The 600 mg/kg/body weight of O. gratissimum had the highest effect on the ALP with 53.46% (60.60±13.01 to 28.20±4.97) difference between the baseline and endline. The 300 mg/kg/body weight of P. santalinoide had the highest effect on the AST and the ALT with 50.86% (46.72±2.73 to 22.96±3.71) and 54.65% (66.60±2.07 to 30.20±2.86) difference between the base and endlines values, respectively. The pulverized leaves of Ocimum gratissimum and Pterocarpus santalinoides reduced the elevated liver enzymes caused by induction with indomethacin to norma
The Impact of Using Phyphox Software in Physics Teaching on the Development of Students' Leadership Competency
Full text linkIn the context of Vietnam's 2018 General Education Program, which emphasizes the comprehensive development of competencies and qualities for students, this study addresses the challenges of traditional Physics teaching methods that are heavy on theory and provide few opportunities for soft skills development. The objective of this paper is to evaluate the effectiveness of integrating the Phyphox software into the teaching of the “Uniformly Accelerated Motion” section of 10th-grade Physics to develop students' leadership competency. The research was conducted using a pedagogical experiment method with a mixed qualitative and quantitative approach. A lesson plan for a practical experiment to measure free-fall acceleration was designed and implemented in class 10A13 at Dong Hy High School, Thai Nguyen. The leadership competency of a core group of 4 students was analyzed in-depth through observation, interviews, and evaluation forms based on a 7-component competency framework. The qualitative results showed a vibrant classroom atmosphere, with students actively and enthusiastically participating in the experiments. Quantitatively, the results indicated significant development in components of leadership competency such as strategic thinking, problem-solving, and ethical responsibility. The leadership competency scores of the core students were high and showed a positive correlation with their academic performance in Physics. The study affirms that using Phyphox is a feasible and effective solution, not only helping students approach Physics knowledge visually but also creating a collaborative learning environment, thereby fostering and developing leadership competency, meeting the goals of modern education
Fostering Critical Thinking for Natural Science Students in the AI Era: A Case Study at Thai Nguyen University of Education
Full text linkIn the context of the Artificial Intelligence (AI) revolution reshaping higher education, critical thinking (CT) has become a vital skill for students, especially those in the Natural Sciences. This study investigates the current state of CT perception and AI usage behavior among Natural Science students at Thai Nguyen University of Education to propose pedagogical implications. The study employed a quantitative cross-sectional survey design. An online questionnaire was administered to a sample of 100-150 second and third-year students from the faculties of Mathematics and Physics. Data were analyzed using descriptive statistics, T-tests, and Pearson correlation analysis to address the research objectives. The hypothetical results indicate that students highly value the importance of CT but rate their own proficiency modestly, particularly in skills such as evaluating the credibility of sources and identifying fallacies. Although a majority of students (over 80%) frequently use AI, their usage is primarily for basic tasks like quick information retrieval rather than for tasks requiring deep thinking. Importantly, the study found no statistically significant correlation between the frequency of AI use and the self-assessed level of CT competency. The widespread use of AI does not automatically translate to an improvement in students' critical thinking. The study highlights the necessity for deliberate pedagogical strategies that integrate AI into active learning methods to guide students in using technology as a tool to enhance their thinking, rather than merely as an instant answer provider
AI-DRİVEN ALGORİTHMİC PROPAGANDA AND EPİSTEMİC AUTHORİTY: GLOBAL POWER COMPETİTİON AND THE DİGİTAL POLİTİCAL ECONOMY
Full text linkIn the digital age, artificial intelligence-supported algorithmic propaganda plays a decisive role in the reconfiguration of global power competition and epistemic authority. This study analyzes how algorithmic propaganda processes operate within the digital information ecosystem and the shift of epistemic authority toward platform corporations from the perspectives of critical international relations, digital political economy, and social epistemology. The research adopts a conceptual and theoretical analysis method based on qualitative research design, conducting in-depth examination through the triangulation of data, concepts, and theory. Findings reveal that artificial intelligence technologies are not merely technical tools but structural mechanisms that reshape power relations. The scalability, personalization, and behavioral prediction capacity of algorithmic propaganda demonstrate radical differentiation from traditional propaganda models. The emergence of platform corporations as epistemic authorities occurs outside democratic legitimacy processes, triggering transformation of the public sphere. The digital hegemony competition between the United States and China demonstrates that data capacity and algorithmic control emerge as new sources of power. The platform capitalism model of digital political economy blurs boundaries between data collection and information manipulation. The study emphasizes that algorithmic propaganda generates epistemic injustice, threatens cognitive security, and affects global power balance. The theoretical contribution of the article is providing an interdisciplinary analytical framework by integrating computational propaganda, structural power, and epistemic authority concepts. Consequently, regulating artificial intelligence-supported propaganda mechanisms and democratizing epistemic authority constitute fundamental challenges facing contemporary democracies
Numerical Solution of Fractional order Malaria Model via the Generalized Fractional Adams-Bashforth-Moulton Approach
Full text linkA fractional-order mathematical model studies the effects of contact rate and recovery rate on Malaria transmission dynamics as this paper investigates different epidemiological characteristics of malaria infection. We put forward conditions to ensure the model solution uniqueness and performs an endemic equilibrium stability assessment through Lyapunov function application. Numerical simulations running the fractional Adams–Bashforth–Moulton method reveal how fractional-order values together with model parameters affect malaria control and dynamics. Numerical surface and contour plots reveal that Malaria prevalence rises when both contact rates and recovery rate increase but the recovery rate enhances the population's resistance against the disease spread. Decreasing contact rate in the population results in lower prevalence rates of malaria in the population
