The surface morphology of micro- and nano- scale fiber determines its application to a great extent. At present, variety secondary microfibers nanofibers, such as porous, wrinkle, groove so on, have been prepared. Among them, grooved fibers are attracting more attention because their unique properties. In this paper, we review the literature on due void-based elongation, wrinkle-based collapsed...

PURPOSE The aim of the present study was to investigate whether previous long-term exposure to manganese (Mn) via inhalation of welding fumes can cause persistent impairment in neuromotor function even long after cessation of exposure. METHODS Quantitative tests of tremor, motor speed, manual dexterity, diadochokinesis, eye-hand coordination and postural stability were administered to 17 reti...

OBJECTIVE To digitally model (three-dimensional, 3D) the course of the pudendal arteries relative to the bony pelvis in the adult male, and to identify sites of compression with different bicycle riding positions as a potential cause of penile hypoxia and erectile dysfunction. SUBJECTS AND METHODS 3D models were made from computed tomography scans of one adult male pelvis (a healthy volunteer...

Abstract This paper presents the results of a theoretical and experimental investigation potential enhanced groove geometries to increase bearing clearance Herringbone Grooved Journal Bearing (HGJB) supported rotor. The study investigates various different complexities their effect on stability threshold particular rotor geometry. obtained from rigid-body rotordynamic model suggest an more than...

Abstract Hydrodynamic herringbone-grooved journal bearings (HGJBs) are analyzed by solving Navier–Stokes and energy equations. It is well known that the load capacity of hydrodynamic may be affected high temperatures low oil viscosity. Therefore, main objective this study to understand pressure distribution HGJBs under different viscosity eccentricity ratios. In paper, 3 configurations studied,...
