To explore the effect of dents on tribological behavior “washers-cage-rollers” system rolling element bearings (REBs), friction and wear properties textured thrust cylindrical roller (81107TN) with different diameters (DAOD, 200, 250, 300 μm), depth (DPOD, 4, 8, 12 μm) as well circumferential interval angle (CFIA, 1.5°, 2.0°, 2.5°) were researched under dry wear. The surface stresses REBs influ...

This study aims to look at ESG reporting in India through the lens of greenwashing, with a focus on companies listed National Stock Exchange under NIFTY 50 index using available scores and assessments. Further, it measure indulgence greenwashing by companies. also analyses attempts highlight factors that influence company’s behaviour, focusing specifically Indian context. Data for empirical cal...

Abstract The pretensioning force in bolted joints enhances the lateral strength of connections, and causes embedment metal washers into wood. Despite significance behavior design joints, its mechanism has yet to be fully understood. In this study, a washer wood along radial direction was examined through three-dimensional nonlinear finite-element analysis (FEA). FEA results were validated by co...

OBJECTIVE To evaluate the efficacy and safety of a new adjustable bulbourethral sling (Argus, Promedon SA, Cordoba, Argentina) in the treatment of male stress urinary incontinence (SUI) after prostate surgery. PATIENTS AND METHODS In all, 48 patients with SUI because of prostatic surgery for prostate cancer (39) or benign prostatic hyperplasia (nine) had a new sling implanted in a multicentre...

The formation of boundary layers on bearing surfaces due to the operational conditions has a significant influence lifetimes and frictional properties. Zinc dialkyldithiophosphate is an anti-wear additive widely used in oil grease formulations that forms beneficial surface layers. Under certain circumstances, this can cause early failure white etching cracks (WEC) formation. By influencing chem...

Microplastics (MP) have been detected in bottled mineral water across the world. Because only few MP particles reported ground water-sourced drinking water, it is suspected that enter during bottle cleaning and filling. However, until today, entry paths were not revealed. For first time, this study provides findings of from well to including washing process. At four bottlers, five sample types ...

We propose the design of a tubular phononic crystal (TPC) for purpose sensing physical properties liquid filling hollow part tube. The TPC is constituted by periodic repetition washers along pipe with advantage avoiding any perturbation flowing fluid element inside Using finite simulations, we demonstrate existence complete as well polarization dependent bandgaps which one can localized modes a...
