For a plane electromagnetic wave at nose-on incidence on a semi-infinite perfectly conducting cone expressions for the surface field components are obtained. These have been programmed for numerical computation and data are presented for the magnitudes and phases as functions of the distance from the tip for three different cone angles. Comparison with results derived from the physical optics a...

Dibutyryl cyclic AMP was administered to 2 patients with severe congestive heart failure. After an intravenous drip infusion of dibutyryl cyclic AMP (300 mg/40 min), marked diuresis and mild improvement of the patients' physical activity occurred. The cardiac index increased and both systemic vascular resistance and pulmonary capillary wedge pressure decreased. Blood glucose and plasma insulin ...

[1] The development of topography within and erosional removal of material from an orogen exerts a primary control on its structure. We develop a model that describes the temporal development of a frontally accreting, critically growing Coulomb wedge whose topography is largely limited by bedrock fluvial incision. We present general results for arbitrary initial critical wedge geometries and in...

BACKGROUND Controversy exists over whether or not single-needle liver biopsies are sufficient to compare histological parameters in patients with non-alcoholic fatty liver disease. AIMS To identify sampling variability, we biopsied four liver specimens per patient, based on biopsy size (needle vs wedge) and location (left vs right lobe), immediately prior to bariatric Roux-en-Y gastric bypass...

The left ventricular (LV) coronary-perfused canine wedge preparation is a model commonly used for studying cardiac repolarization. In wedge studies, transmembrane potentials typically are recorded; whereas, extracellular electrical recordings are commonly used in intact hearts. We compared electrically measured activation recovery interval (ARI) patterns in the intact heart with those recorded ...

This paper describes a hybrid method combining the method of moments (MM) with asymptotic current expansions for the higher frequency range. The physical optics (PO) approximation represents such an asymptotic current expansion which is rather simple to apply. However, for flat polygonal scatterers or scattering bodies containing wedge–like elements, the accuracy is improved by taking into acco...

This paper describes certain properties of the fundamental group of the shrinking wedge of circles. Covering space theory is an inadequate tool since the shrinking wedge of circles is not semi-locally simply connected. We conclude with the fact that the shrinking wedge of circles is not homotopy equivalent to the wedge product of a countable number of circles.

Mine closure includes the rehabilitation process, which is a continuous programme aimed at restoring physical, chemical, and biological quality that has been harmed by mining to level acceptable all individuals involved. BIT Mesra was assigned R&D project on development of dragline dump profile both on-going closed mines. As part study, stability highwall investigated for this mine. The final q...

[1] Dynamic pore pressure changes in the overriding wedge above a shallow-dipping plate interface significantly affect the rupture dynamics of shallow subduction zone earthquakes and their tsunamigenesis. For a wedge on the verge of Coulomb failure everywhere including the basal fault, the dynamic pore pressure increase due to up-dip rupture propagation leads to widespread yielding within the w...

Abstract—This paper deals with the theoretical and numerical investigation of magneto hydrodynamic boundary layer flow of a nanofluid past a wedge shaped wick in heat pipe used for the cooling of electronic components and different type of machines. To incorporate the effect of nanoparticle diameter, concentration of nanoparticles in the pure fluid, nanothermal layer formed around the nanoparti...
