Renal control of effective circulating volume is key for circulatory performance. When renal Na+ excretion is inadequate, blood pressure rises and serves as a homeostatic signal to drive natriuresis to re-establish effective circulating volume (ECV). Recognizing that hypertension involves both renal and vascular dysfunction, this report concerns proximal tubule Na+/H+ exchanger 3 (PT NHE3) regu...

Radiometer Blood Micro-system 2 was used in studies designed to, (a) compare the mean blood gas and acid-base values of 38 normal horses and 20 horses with chronic obstructive pulmonary disease (COPD), (b) determine the means and standard deviations of blood gas and acid-base values of Thoroughbred horses in training, and (c) investigate the relationships between clinical data, blood gas values...

We present exact results for the contact forces in a three dimensional static piling of identical, sti and frictionless spheres. The pile studied is a pyramid of equilateral triangular base (“stack of cannonballs”) with a FCC (face centered cubic) structure. We show in particular that, as for the two dimensional case, the pressure on the base of such a pile is uniform. c © 1999 Elsevier Science...

We present models for the thermal and mechanical equilibria of slender magnetic loops on rapidly-rotating stars. These loops are embedded within an arcade located on the stellar equator. The loop properties are governed principally by the specified base pressure and conductive flux. While rapid rotation is important in determining the pressure structurewithin the loop, its main effect on the lo...

PURPOSE Sonography provides a fast, portable, and noninvasive method for patient assessment. However, the benefit of providing real-time ultrasound (US) imaging and fluid quantification shortly after patient arrival has not been explored. The objective of this study was to prospectively validate a US hemoperitoneum scoring system developed at our institution and determine whether sonography can...

The proximal tubule Na(+)/H(+) exchanger 3 (NHE3), located in the apical dense microvilli (brush border), plays a major role in the reabsorption of NaCl and water in the renal proximal tubule. In response to a rise in blood pressure NHE3 redistributes in the plane of the plasma membrane to the base of the brush border, where NHE3 activity is reduced. This NHE3 redistribution is assumed to provo...

building pounding occurs between two adjacent buildings with small gap or without sufficient separation distance. it leads to damage buildings during earthquake due to impact. many researchers have investigated building pounding based on impact force reduction and energy dissipation increase, when two buildings collide with each other. in numerical investigations, using specific link element, i...

Radiatively-driven flow in a luminous disk is examined in the subrelativistic regime of (v/c), taking account of radiation transfer. The flow is assumed to be vertical, and the gravity and gas pressure are ignored. When internal heating is dropped, for a given optical depth and radiation pressure at the flow base (disk “inside”), where the flow speed is zero, the flow is analytically solved und...

Tractor hydraulic power is used on a wide range of agricultural implements; however, the availability of operational hydraulic data at points other than full engine throttle position is limited. Operators could utilize this hydraulic data to maximize field efficiency and minimize machinery costs when determining suitable machinery for field operations. A field usable hydraulic test apparatus ca...

Hydrous silicate melts appear to have greater compressibility relative to anhydrous melts of the same composition at low pressures (<2GPa); however, at higher pressures, this difference is greatly reduced and becomes very small at pressures above 5GPa. This implies that the pressure effect on the partial molar volume of water in silicate melt ( partial differentialV-H2O/ partial differentialP) ...
