Girls Academic Performance in Science Subjects: Evidences from the Industrializing and Least Industrialized Countries

The study reviewed the published empirical evidence on girls’ academic performance in science subjects in Industrializing and Least Industrialized Countries. Empirical evidences suggest that girls have been outperforming boys in education across the globe. Policy makers and academics have extensively studied this gender reverse change in the context of technologically advanced countries. The issue is an emerging phenomena in the context of industrializing and least industrialized countries and has received some academic attention in the last two decades. This gender reversal change in academic performance is an interesting trend in the context of industrializing and least industrialized countries. Nevertheless, girls as compared to boys, are not doing well in science subjects: technology, engineering and math (STEM). This review paper seeks to give a succinct picture of gender differences in academic performance in STEM subjects in the socio-cultural contexts industrializing and least industrialized.  The findings of our umbrella review of different studies in the developing countries show girls’ underperformance in STEM subjects in the industrializing and least industrialized countries. Findings (skimmed from a number of empirical studies) suggest boys’ outperformance in STEM subjects

Trend of Research Visualization of Learning, Classroom, and Class Participation in Higher Education Institutions: A Bibliometric Analysis from 2001 to 2020

The main objective of this research is to inspect the classroom environment, student learning, interactive learning, class participation, higher education institutions using bibliometric analysis from 2001 to 2020. For the scientometric analysis, we extracted data from the Science Citation Index database, Web of Science (Core Collection) using a searched query. The data was extracted on February 27, 2021 (GMT-4:29 AM). Further, the period was 2001 to 2020. There were 6340 published documents were found. The study findings illustrate that the topic of higher education institutions was on top of the topic list and a major proportion of published documents was an article. The English language was used and the frequency of published documents was gradually increased as per year. The author \u27Lepori B’ was on the top with 13 publications and 205 citations. Further, organization Univ. Colorado and United States country was on top of the top. Furthermore, higher education was the top keyword and computer & education were the top sources of published documents. Likewise, the top funding agency was \u27National Science Foundation NSF\u27. In the end, a conclusion was drawn

Enhancement of Mechanical & Ballistic Properties of Quenched & Tempered (Q & T) High Strength Low Alloy (HSLA) Steel Weldments.

HSLA (High Strength Low Alloy) Q & T (Quenched & Tempered) Steel Weldments  prone to number of Welding defects as regard to the Mechanical & Ballistic properties. In this investigation an attempt has been made to design such Welding methodology which gives sound Weldment by keeping the adequate Mechanical and Ballistic properties intact as well.Uptill now Hardfaced layer was deposited in between the ASS (Austenitic Stainless Steel) Welding layers of Q & T HSLA Steel Weldments for good Ballistic & Mechanical properties but this didn’t work well and cracks were observed in between Base metal and Hardfaced layer.This study was made ,as extracted from literature, to eliminate these cracks and defects by depositing soft buttering layer in between the Base Metal and Hardfaced layer and also utilized the newly recommended class of consumables ,i.e. LHF (Low Hydrogen Ferritic) as well.The said design methodology exhibited adequate results. &nbsp
