Pervasiveness of inorganic gunshot residue (IGSR) in handguns after cleaning and conditioning procedures

Journal of Forensic Sciences, Volume 69, Issue 3, Page 1035-1044, May 2024.
Abstract Memory effect in firearms that is, the possibility for a weapon to release inorganic particles whose elemental composition depends on its entire shooting history, is responsible for most of the interpretation difficulties encountered in forensic gunshot residue analysis. The presence of residues chemically inconsistent with the last discharged

Deform 3D Simulation and Experimental Study in Machining of AISI 1020 Mild Steel

Journal of Engineering, Volume 2024, Issue 1, 2024.
The drilling process plays a crucial role in the assembly process of modern‐day manufactories. One of the major causes of component rejection during drilling operations is the incorrect selection of spindle speed and feed rate. Therefore, this study aimed to investigate the impact of process factors such as spindle speed and feed rate on torque, thrust
