PREVALENCE OF HYPERDENSE PARASPINAL VEIN SIGN IN PATIENTS WITH SPONTANEOUS INTRACRANIAL HYPOTENSION WITHOUT DURAL CSF LEAK ON STANDARD CT MYELOGRAPHY

Party Pack PURPOSE:A recently identified and treatable cause of spontaneous intracranial hypotension (SIH) is cerebrospinal fluid (CSF)-venous fistula, and a recently described computed tomography myelogram (CTM) finding highly compatible with but not diagnostic of this entity is the hyperdense paraspinal vein sign.We aimed to retrospectively measu

In this study, the wake characteristics of an arc blade were measured by the wind tunnel experiment; the characteristics were defined as the width of the wake, diameter of the vortex, ratio of the DISH vortex scale, and the local lift.The influence of the angle of attack on the aerodynamic noise of the blade was quantitatively predicted by using th

The future of aviation is unmanned and ultimately autonomous.As part of this effort the Office of Naval Research, in partnership with the Naval Air Systems Command, has initiated the advanced autonomous air-to-air refueling system (A4RS) future naval capability (FNC).The A4RS FNC intends to set the interface requirements for any uncrewed aerial sys

Many urban streets are designed with on-street bike lanes to provide right-of-way for bicycle traffic.However, when bicycle flow is large, extensive passing maneuvers could occupy vehicle lanes and thus cause interferences to vehicle traffic.The primary objective of this study is to evaluate how bicycle traffic affects vehicle operation on urban st

Good knowledge of cross section neutron induced reactions on Zr becomes of importance due to the use of zirconium as structural material in reactors, its applicability in neutron dosimetry and the theoretical model testing.Thin Zr foils (0.05 mm thickness, 99.2% purity) were irradiated in the quasi-monoenergetic p-Li neutron fields, Camera Bags the
