It is generally believed that, on slender delta wings, there is a critical state at which strong asymmetric vortices are found along the leading edge on the lee-side of the delta wing. These asymmetric vortices can lead to high lateral forces even when slender delta wing is at the zero angle of yaw. Some experimental studies reported recently, cast considerable doubt as to the validity of the a...

abstract background: increase in nitric oxide (no) concentration accompanied by alteration in peritoneal immune defense reactions is involved in the pathogenesis of endometriosis. asymmetric dimethylarginine is an endogenous competitive inhibitor of no synthase. this study was designed to compare no metabolite (nitrite), asymmetric dimethylarginine, and estradiol concentrations in serum and per...

We calculate the friction force acting on a hard cylinder or spherical ball rolling on a flat surface of a viscoelastic solid. The rolling-friction coefficient depends non-linearly on the normal load and the rolling velocity. For a cylinder rolling on a viscoelastic solid characterized by a single relaxation time Hunter has obtained an exact result for the rolling friction, and our result is in...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background : distraction osteogenesis is an established option for reconstruction of amputated fingers. in contrast to the primary method of distraction osteogenesis, using kirschner wire (k-wire) as an internal fixator is not common today. this study was conducted to evaluate distraction osteogenesis with and without k-wi...

A magnetic field sensor was developed using the asymmetric giant magnetoimpedance (AGMI) effect. Amorphous ferromagnetic (Fe0.06Co0.94)72.5Si12.5B15 wires were used in this study. The 2-cm-long wire showed an approximately 88% effect, and 7-cm-long 197% When two micromagnets placed 1 cm from ends of wire, a distortion peak shapes GMI curve observed, asymmetry created by micromagnets. 148% AGMI ...

Wire electrical discharge machining (WEDM) is a method to cut conductive materials with a thin electrode that follows a programmed path. The electrode is a thin wire. Typical diameters range from .004" - .012" (.10mm - .30mm) although smaller and larger diameters are available. WEDM is a thermal machining process capable of accurately machining parts with varying hardness or complex shapes. WED...
