This work reviews the failure modes, mechanisms and causes of bearings in mechanical
equipment. Bearings are among the most important basic mechanical components. Their …

Formulating nanofibers loaded with active compounds for biomedical purposes has recently
drawn great attention. In this work, polycaprolactone (PCL) was blended with peppermint oil …

Photochromic and long‐lasting photoluminescent transparent, rigid, ultraviolet (UV)
protective and superhydrophobic poly (methyl methacrylate)(PMMA) plastic able to switch …

This paper analyses failures of one hundred idler roller bearings of a belt conveyor. It
indicates possible causes of damage and proposes measures to eliminate them or at least …

Rotating machinery failure analysis requires signal preprocessing to extract fault-related
information. However, to promote accurate condition monitoring of bearing following two …

Generally, the determination of the wear in the mechanical systems is done by checking the
critical components in periodic maintenance or by monitoring the secondary indicators such …

Skid damage to mainshaft bearings on aeroengines severely reduces aircraft reliability. In
this study, a batch of cylindrical roller bearings extracted from mainshaft of inservice …

For angular contact ball bearings (ACBBs), the unacceptable vibrations caused by the
manufacturing errors including the roundness and waviness imperfections can greatly …

Rolling element bearings play an essential role in rotating machines. It is estimated that
more than 90% of rotating machines contain bearings, and therefore their failure may lead to …

The study was undertaken to examine how documented systems are used to aid the
activities that were applied to ameliorate physical assets reliability. A documented system …
