The impeller under consideration is a rotor wheel of a centrifugal compressor, made of 17-4PH martensitic precipitated hardening stainless steel.Its total operating lifetime was estimated to 80,000 h, but it fractured beforehand, 4 days Ice Bucket after the scheduled overhaul without any observed pre-symptoms.The important causes of the failure wer
Background: Tobacco chewing is attributed to oral cancer.Prediction of cancer development by genotoxicity analysis is a major challenge to identify tobacco users at greater risk.Therefore, present study aimed to analyze tobacco related genotoxic effects in chewers monitoring micronuclei (MN) and chromosome aberrations (CA).The biomarkers were compa
Abstract Recent seismic events have unequivocally highlighted the susceptibility of fault-crossing bridges to the synergistic effects of ground surface vibrations on either side of the fault plane and the tectonic dislocations arising from fault-induced surface Chairs ruptures.This study delineates both seismic and parametric response analyses of f
Warm anoxia-reoxygenation induces ferroptotic cell death in mouse proximal renal tubular epithelial cells (RPTECs), whereas RPTECs of the native hibernator Syrian hamster resist cell death.Clarifying how hamster cells escape ferroptosis may Hoodies/Fleece reveal new molecular targets for preventing or ameliorating ischemia-reperfusion-induced human
