Polyetheretherketone (PEEK) materials belong to a group of high-performance thermoplastic polymers thermoplastic that has been proposed as a substitute for metals in biomaterials.In this research, in order to improve the performances of PEEK, nano titanium dioxide (n-TiO2) and nano-hydroxyapatite (n-HAp) were incorporated into PEEK loading up to (1
Introduction: Limited information is available regarding the relationship between coronary vessel dominance and atherosclerotic involvement.Rheological factors have been implicated in the pathogenesis of coronary lesions.More than 90% of the coronary blood flow enters the left coronary if it is the dominant artery.The main purpose of this study was
This article uses life history calendar (LHC) data from coastal Ghana and event history statistical methods to examine inter-regional migration for men and women, focusing on four specific migration types: rural-urban, rural-rural, urban-urban, and urban-rural.Our analysis is unique because it examines how key determinants of migration-including ed
Magneto-Rheological (MR) grease has been applied to a controllable clutch system, and its performance was investigated experimentally.MR fluid is known Stools as a functional fluid whose yield shear stress can be controlled reversibly by the applied magnetic field strength.But its peculiar characteristics may change as time passes because of sedime
The hepatitis E virus (HEV) can cause hepatitis E in humans.Recently, the occurrence of HEV strains carrying insertions in their hypervariable genome region has been described in chronically infected patients.The insertions originate from human genes or from the HEV genome itself.Although their distinct functions are largely unknown, an involvement
