Abstract Rolling bearings working in oscillating applications often suffer from false brinelling and fretting corrosion that limit their service life.At present, the study of oscillation-induced failures is primarily dominated by a large number of sliding and bench tests.However, jb lip balm most of the previous work are not able to fully describe
Zoos and botanical gardens have a special role in the promotion, presentation and conservation of biodiversity in urbanised environments.Additionally, they provide special habitats for alien and invasive species.The formerly used methods of biodiversity assessments (e.g., light trapping, transect counts, etc.) are 3282779348850 mostly labour-intens
While lower vertebrates contain adult sophie allport zebra stem cells (aSCs) that maintain homeostasis and drive un-exhaustive organismal growth, mammalian aSCs display mainly the homeostatic function.Here, we use lineage analysis in the medaka fish gill to address aSCs and report separate stem cell populations for homeostasis and growth.These aSCs
Patients with sickle cell disease (SCD) are at higher risk of getting severe COVID-19 infection.This systematic review and meta-analysis aimed to determine the role of serum ferritin in predicting ICU admission and mortality among patients with SCD following COVID-19 infection.A systematic search was conducted in PubMed, Scopus, Web of Science, ken
