The One-Way Light Speed Is Measurable: Nonequivalence of the Lorentz Transformations and the Transformations Preserving Simultaneity and Spacetime Continuity
Authors: Gift Stephan , Spavieri Gianfranco 
Published: January 2025

Based on our analysis of the GPS and other physical effects, we confirm the well-known view that the Lorentz transformations (LT) fail in interpreting light propagation along a closed moving contour. We show in detail that, with the LT based on light speed invariance, in the standard linear Sagnac effect, a photon cannot cover the whole closed contour in the measured interval \(T\). Thus, the LTs imply a breach in spacetime continuity related to the "time gap" due to relative simultaneity. Our results invalidate Mansouri and Sexl’s conventionalism of the speed of light and the contended equivalence between relative and absolute simultaneity[1].

Published: January 2025

Background: Obesity has emerged as a global epidemic in children with a spectrum of psycho-social and medical consequences manifesting across the lifespan. Obesity-related morbidities that emerge early in childhood are an alteration in glucose metabolism and fatty infiltration of the liver. Non-alcoholic fatty liver disease (NAFLD), chronic liver disease is a metabolic complication of obesity.
Objective: To identify the prevalence of NAFLD among obese children and anthropometric and metabolic abnormalities among these obese children with NAFLD.
Methodology: This was a cross sectional study included 50 obese children and adolescents, attending Paediatric Endocrine OPD, BIRDEM from June 2010 to December 2010. BMI e” 95th centile for age and sex was used as an anthropometric marker to diagnose obesity. Obesity with dismorphism, endocrine, chromosomal abnormalities, chronic liver diseases due to infectious or metabolic causes were excluded from the study. Fasting blood samples were collected for measurement of blood glucose, lipid profile, FT4, TSH and SGPT. Fatty liver was diagnosed by USG which includes increased echogenicity of liver, blurring of vascular margins and increased acoustic attenuation.
Results: The prevalence of fatty liver disease among obese children was 36% with male predominance(M72.2%, F 27.8%). Mild NAFLD was 72% followed by moderate 28%. High Cholesterol, high LDL and high SGPT were more prevalent in obese children with NAFLD which was statistically significant (P <0.004, <0.05and <0.04 respectively.
Conclusion: Obesity with liver disease can get overlooked among the plethora of adverse outcomes related to childhood obesity. Our study was attempted to find out the obese children with NAFLD and related metabolic abnormalities, so that delebarate strategies could be taken to prevent this irreversible liver damage among obese children.

Published: January 2025

Background: The developmental, medical, economic and social impacts of acute malnutrition in children are serious and long lasting for individuals, families, communities and countries. Malnutrition in childhood damages a child’s both physical and cognitive development and this damage is largely irreversible. These ultimately perpetuate illness, poverty and inequality. Childhood acute malnutrition is multifactorial in origin and majority of them are preventable. Objective: The purpose of this study was to identify the factors of acute malnutrition among under five years children in northern Bangladesh. Methods: This case-control study was carried out in Chapainawabganj general hospitals, Chapainawabganj. Total 180 children aged 6-59 months (90 cases-WHZ < -2 and 90 control-WHZ ≥ -2) were included for this study based on selection criteria. Informed written consent was taken from the guardians of all children. Data were recorded by using a semi-structured questionnaire. Height and weight of children and their parents were measured by measuring tape and weight machine. BMI of children and parents, and weight-for-height Z scores of children were calculated. Collected data were analyzed by the SPSS 23. Chi-squared (ꭓ2) test and unpaired t-test were performed to compare the frequencies and means between the groups. Results: The mean age of the acute malnourished children was 25.84±15.09 months with slight male predominance (male female ratio 1.14:1). The mean weight for height Z score of the cases was -2.93±0.41. Monthly family income <10000 BDT, younger mother (age ≤20 years), younger father (age ≤20 years), less educated mother (Illiterate or upto primary), less educated father (Illiterate or up to primary), undernourished mother (BMI <18.50 kg/m2) and predominant breast feeding stop before 4 months had found to be significantly associated with acute malnourishment (p<0.05). Conclusion: Acute malnutrition was found to be significantly associated with low monthly family income, younger mother and father, less educated mother and father, undernourished mother and early stop of predominant breast feeding.

Published: January 2025

The success of an education is associated with the high and low learning outcomes that have been achieved. The results of mathematics learning are very important, because they measure whether the learning that has been carried out so far has been successful or not. One learning model to improve mathematics learning outcomes is the reciprocal teaching learning model. The aim of this research is to analyze articles on the topic of mathematics learning outcomes in the reciprocal teaching model. The method used in this research is the meta analysis method. The research obtained results that there were three articles with effect sizes in the medium category and three articles with effect sizes in the strong category. The average effect size value of the six articles analyzed was 1.27 in the strong category. So it shows that the reciprocal teaching learning model has a strong influence in improving students' mathematics learning outcomes. Apart from that, the results of hypothesis testing were carried out using the t test, namely t test = 10.89 > 1,968 = t table. This shows that the average mathematics learning outcomes of students using the reciprocal teaching learning model are better than the average mathematics learning outcomes of students using the conventional learning model.
