the effect of a combined system of the bed suction and jet injection as a pier-scour countermeasure on the turbulent flow field is studied in a laboratory flume using an acoustic doppler velocimeter (adv). the three components of the velocities in the vertical symmetry plane in the equilibrium scour hole in front and rear of the pier under 3-jet injections and bed suction rate qs/q0 = 2%located...

sludge drying bed is preferred to mechanical methods due to the need for very simple technology. due to restriction of natural dewatering, we tried to eliminate some of these limitations by the tests and studies of assumptions. in this study, the effect of hydrostatic suction and sludge chemical conditioning has been studied in the natural sludge dewatering optimization. at first, hydrostatic s...

The effect of a combined system of the bed suction and jet injection as a pier-scour countermeasure on the turbulent flow field is studied in a laboratory flume using an Acoustic Doppler Velocimeter (ADV). The three components of the velocities in the vertical symmetry plane in the equilibrium scour hole in front and rear of the pier under 3-jet injections and bed suction rate Qs/Q0 = 2%located...

rest of the patients may get but scant nursing attention and are generally disturbed by the noise of machines and the frequent visits of doctors. A great deal of space is required around the bedside to allow for bulky respirators, suction apparatus, oxygen cylinders, E.C.G. oscilloscopes, etc., and usually at least two bed spaces are occupied. Since piped oxygen and suction are not universally ...

Bed rest deconditioning leads to physiological cardiac atrophy, which may compromise left ventricular (LV) filling during orthostatic stress by reducing diastolic untwisting and suction. To test this hypothesis, myocardial-tagged magnetic resonance imaging (MRI) was performed, and maximal untwisting rates of the endocardium, midwall, and epicardium were calculated by Harmonic Phase Analysis (HA...

A variety of grafting procedures using autologous melanocytes have achieved promising results in the treatment of vitiligo. We here report on the preparation of an adequate graft recipient bed by pulsed Erbium-YAG laser skin ablation. In particular, for irregular lesions on delicate sites, which cannot be approached by utilization of suction blisters or dermabrasion, this technique may offer a ...

Chyle leak following axillary lymph node clearance is a rare yet important complication. The treatment of postoperative chyle fistula still remains unclear. Conservative management is the first line of treatment. It includes axillary drains on continuous suction, pressure dressings, bed rest, and nutritional modifications. The use of somatostatin analogue is well documented as a treatment for c...

The surgical retractors are integral parts of almost any surgery. Surgical aspirators were introduced into the surgical field after the development of powered suction devices. This new suctioning power improved the visibility of the surgical fields tremendously. The retractors being the aid in access to surgical filed come in numerous shapes and sizes for various procedures. In the recent past,...

TO THE EDITOR: Zhang et al. (6) elegantly discuss the concept of diastasis (static equilibrium volume) and diastolic suction and address the idea that diastasis provides a measure of ventricular equilibrium. While this definition provides a very useful working model, one must also consider differences between early diastolic filling and diastolic suction when examining ventricular function. Ina...
