Global warming and greenhouse gas emissions pose severe threats to environmental sustainability. A sustainable environment is a prerequisite for long‐term socioeconomic growth and human survival. Green technology is brought about by a country's economic and financial openness, and education provides knowledge to the public and labor, contributing to environmental sustainability. Thus, this research aims to unveil the liaison between human capital, trade openness, and environmental quality for Russia, Brazil, India, China, and South Africa (BRICS) countries from 1998 to 2018. Several econometric methods, including the Driscoll–Kraay standard errors and the Dumitrescu–Hurlin causality approaches, reveal long‐run and causal relationships among the modelled indicators. The Driscoll–Kraay standard error results show that human capital is negatively related to carbon dioxide emissions (CO2 emissions). Imposing high tariffs and excise duties, changing tax structures, discouraging the inflow of polluted commodities, and encouraging green trade can help BRICS combat high environmental pollution. The results show that a one‐point increase in human capital in models 1 and 2 can reduce CO2 emissions by 1.5279 and 0.1538 points, respectively. In contrast, a 1% growth in trade can lead to a rise in CO2 emissions of 0.3731% and 0.2384%, respectively. Similarly, financial development and energy consumption result in high CO2 emissions in the long run. Moreover, a feedback effect of the human capital index on CO2 emissions is discovered. As a result of the findings, the government and responsible authorities should provide financial support and encourage investments in the region's energy‐resourceful and sustainable green projects.

Objective: This study aimed to assess the frequency of internet gaming addiction among undergraduate medical students of Karachi, its effect on their academic performance, and their overall health status. Methods: This cross-sectional study was conducted in selected government and private medical colleges of Karachi from November 2021 to March 2022. Medical students, who were enrolled in year 1 to year 5 of undergraduates health sciences programs of government and private sector of Karachi and had a smartphone and internet connection for past 1 year were included in the study. Internet gaming disorder scale (IGDS-9) was used to determine the proportion of addicted medical undergraduates. Results: Out of 400 medical students, 212 (53%) students were at risk of getting addicted and 13 (3.3%) students were found to be addicted to internet gaming. Male students were found significantly higher at risk of developing internet gaming addiction and were found to be more addicted as compared to female students i.e., 202 (50.5%) vs. 198 (49.5%) (p-value < 0.001) respectively. Students who had a higher-grade point average (GPA) 230 (57.5%) were significantly lesser at risk of developing internet gaming addiction as compared to 170 (42.5%) students who had a lower GPA (p-value 0.003). Conclusion: More than half of the study population with predominant males was at risk of developing gaming addiction and they exhibited more health-related effects. Their academic grades were also affected. It is imperative to counsel this cohort for reducing the effects of internet gaming addiction. [ABSTRACT FROM AUTHOR]

This study details the irradiation of pure (99.995%) and immaculate metallic Zinc using Nd: YAG laser (1064 nm, 10 mJ, 9–14 ns). The influence and impact of multiple laser shots on the formation of microstructures and crystal structure orientations is assessed. Arrays of ablated craters are machined on the whole surface of the target to probe the electrical and topographical characteristics of laser-treated surfaces. Irradiated samples are examined by multiple characterizing techniques such as scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), and a four-point probe for electrical conductivity measurements. SEM and AFM analysis exhibited the formation of laser-induced ripple structures with periodicity sheerly dependent on laser shots. A comparison of surface topography of the virgin and treated samples disclosed a pronounced modification in surface texture. The XRD patterns of laser shined targets indicate no momentous structural change in the crystal structure, whereas the measurements on the electrical conductivity of the irradiated surfaces exhibit an exponential descending trend with an augmentation in laser shots.

Objective: To establish the occurrence of Scianna blood group alleles via genotyping in Pakistani blood donors. Study Design: Cross-sectional Analytical study. Setting: Department of Hematology, Army Medical College (AMC) in association with the Armed Forces Institute of Transfusion (AFIT) Rawalpindi. Period: January 2019 to January 2020. Material & Methods: In this study 300 blood donors were incorporated after taking informed consent; DNA was extracted from their EDTA anticoagulated blood samples and tested for SC*01 and SC*02 alleles by Sequence-Specific Primer Polymerase Chain Reaction (PCR-SSP), which was ensued by gel electrophoresis. The allele frequencies were established and Hardy Weinberg equilibrium was determined. Chi-square test was applied to compare the observed and expected genotype frequencies as well as for comparison with published allele frequencies of other populations. We used SPSS version 22 for the analysis of study data. Results: All donors were homozygous for SC*01, demonstrating allele frequency for SC*01 nearly 1.00. Genotype frequencies were congruent with the Hardy Weinberg equilibrium. The difference between the allele frequencies of SC*01 and SC*02 alleles of population of Pakistan was not statistically significant when compared to those of other populations. Conclusion: This maiden research illustrates Scianna blood group distribution in Pakistani community by PCR-SSP. This method is cheap and proficient and can be applied in developing nations. The findings of this study can aid in the production of local red cell panels, detection of uncommon blood types, and setting up of a domestic rare blood donor platform. [ABSTRACT FROM AUTHOR]
