Evaluation of Morbidity and Mortality in Iatrogenic Colonic Perforation During Colonoscopy: A Comprehensive Systematic Review and Meta-Analysis.

This systematic review and meta-analysis explores the clinical and patient-specific factors contributing to increased morbidity and mortality following iatrogenic colonic perforation (ICP) during routine colonoscopy. A comprehensive search of Scopus, PubMed (Medline), Embase, and Google Scholar was conducted, reviewing studies published between 2010 and 2024. Data were synthesized through thematic analysis for qualitative data and meta-analysis for quantitative outcomes.

Machining performance, economic and environmental analyses and multi-criteria optimization of electric discharge machining for SS310 alloy.

With the expansion of the manufacturing sector, it has become crucial to incorporate sustainable production methods in order to remain competitive in the market. This study focuses on addressing the needs of the manufacturing industry by conducting a sustainability analysis of electric discharge machining for SS310 alloy. The analysis explores the impact of various electrode materials, for instance, copper and brass, as well as different machining variables, including discharge current (I = 4-12 A), spark gap (SG = 6-12 mu), pulse duration (Pon = 15-45 μs), and duty cycle (DC = 75-85%) using Taguchi method.

Characteristics of higher education students who reported sexual violence: a Nigerian national study.

Background: Sexual violence among higher education students is a global public health problem. Identifying the characteristics of students who report victimization can serve as basis for programmes that target vulnerable students.

Methods: The study was conducted among 30,114 Nigerian higher education students.

Application of non-ionic liquids-based modified dielectrics during electric discharge machining (EDM) of Ti6Al4V alloy to enhance machining efficiency and process optimization.

The non-conventional manufacturing technologies are notorious when it comes to productivity and processing time in production-related industries. However, the aerospace and other high-end sectors enjoy another quality matrix of these processes and compromise on the processing time. For instance, the machinability of hard-to-cut materials such as Ti6Al4V aerospace alloy for micro-impressions is challenging and commonly carried out through non-conventional processes.
