The possibility of sympathetic vasoconstrictor control of blood flow to active muscles was studied in dogs during graded exercise by comparing the blood flow in the normal with that in the sympathectomized hind limb. Blood flow was measured by electromagnetic flow transducers around each external iliac artery, or inferred from the oxygen saturation of blood samples from the common iliac veins. ...

Abstract Nonlinear saturation mechanism of ion-temperature-gradient turbulence at finite normalized pressure is identified by analysis the nonlinear entropy transfer in global gyrokinetic simulations turbulence. Turbulence such electromagnetic and often exhibits non-saturation due to a lack zonal flows influence magnetic fluctuations local simulations. The present study identifies new caused tu...

[1] The paper investigates the influence of relative bend curvature on secondary flow, energy losses, and turbulence in sharp open-channel bends. These processes are important in natural streams with respect to sediment transport, the bathymetry and planimetry, mixing and spreading of pollutants, heat, oxygen, nutrients and biological species, and the conveyance capacity. Laboratory experiments...

Background During exercise, there is an increased demand for oxygen. Increasing blood flow may provide an ergogenic effect. Dietary nitrate supplementation, such as pomegranate extract (PE), has been linked to reduced vascular resistance, enhanced vasodilation, and increased blood flow to possibly improve exercise efficiency. The purpose of this study was to evaluate the effects of acute PE sup...

The multi-actuator load-sensitive (LS) system has gained widespread usage in engineering machinery applications due to its energy efficiency, exceptional composite action performance, and precise tuning capabilities. However, when the demand for load flow exceeds supply of hydraulic pumps, saturation conditions may arise thereby impacting coordination actions diminishing sensitivity characteris...

The karstic Rijab Spring with an average discharge of 3290 l/s is located in the Alvand River basin in the northwest of the Zagros, Iran, which drains Asmari formation. To investigate groundwater flow in the catchment area of the Spring, the physicochemical parameters include major cations and anions, discharge, EC, pH, and temperature were studied from September 2000-2002. The results indicate...

Abstract We perform a qualitative and quantitative analysis of various multi-frame color optical flow methods for synthetic and real panning and zooming image sequences. We show that optical flow accuracy improvement can be slightly improved if color images are available instead of gray value or saturation images. We show the usefulness of a directional regularization constraint for computing o...
