The doppler color flow imaging method was employed to detect the vesicoureteral reflux. The ultrasound examination was performed by using the doppler color flow imaging system. Ultrasonic sector scan was carried out by the use of the 3.75 MHz phased array and/or conbex array transducer with a transabdominal approach. The flow in the bladder from the ureteral orifice to the bladder was detected ...

I A simple, cheap and reliable method of measuring rheological properties of massecuites and molasses is described. This involves measuring the head loss across an orifice for a given flow rate. Comparisons between results obtained with the orifice viscometer and a pipeline viscometer are presented. INTRODUCTION I The measurement of the rheological properties of massecuites and molasses is impo...

The PIS A-method, Proximal Isovelocity Surface Area, is a method for quantifying regurgitant flow through the mitral valve. The volumetric flow is calculated as the velocity at the center line times the iso-vehcity area. Unfortunately, this method is correct only for a non-viscous fluid flowing towards an orifice with zero radius. In order to study effects from a viscous fluid as well as influe...

Vertisol soils, which cover large lands in irrigated areas Turkey and the world, swell when wet form deep cracks dry. These properties of soils cause a significant decrease irrigation efficiency irrigating with surface methods, thus causing water insufficiency drainage problems. If appropriate time, flow rate furrow-border lengths are used, application can be increased these soils. For this pur...

Structural Integrity Meter Verification is a robust new Coriolis verification technology which uses the onboard electronics to very accurately measure the stiffness of the flowtubes. The flow tube stiffness is directly related to the flow calibration factor and is uninfluenced by process conditions. Meter Verification compares the measured stiffness to the factory baseline stiffness to confirm ...

OBJECTIVES We attempted to determine the accuracy and pitfalls of calculating the mitral regurgitant orifice area with the proximal isovelocity surface area method in a clinical series that included patients with valvular prolapse and eccentric jets. BACKGROUND The effective regurgitant orifice area, a measure of lesion severity of mitral regurgitation, can be calculated by the proximal isove...
