PURPOSE We describe the pathophysiology, differential diagnosis and urodynamic findings in patients with a large capacity bladder. MATERIALS AND METHODS This was a retrospective, observational study of 100 consecutive patients with voiding dysfunction and a cystometric bladder capacity of greater than 700 ml. Clinical data, cystometric bladder capacity and other urodynamic findings were evalu...

PURPOSE The American Urological Association (AUA) symptom index was originally designed to assess the severity of lower urinary tract symptoms in men with benign prostatic hyperplasia. Data concerning the clinical application of the AUA symptom index to women are sparse. We evaluated the significance of the AUA symptom index in women with urodynamically defined bladder outlet obstruction. MAT...

Moisture in the main cable is cause of steel wire corrosion. Modern suspension bridges utilize dehumidification systems to prevent The ventilation experiment can help selection system parameters. This research based on Xihoumen Bridge obtain design parameters system. According experiment, suitable distance 150–180 m; pressure loss with a length 150 m 200–300 Pa, so inlet should be higher than 3...

In this numerical study, the heat transfer performance of shell-and-tube exchangers (STHXs) has been compared for two different tube arrangements. STHX having 21 and 24 tubes arranged in inline staggered grid considered analysis. Shell-and-tube exchanger with arrangement observed to provide lesser thermal stratification as arrangement. Further, study variation mass flow rate shell-side fluid co...

A macroscopic elastic description of stresses in static, preloaded granular media is derived systematically from the microscopic elasticity of individual inter-grain contacts. The assumed preloaded state and friction at contacts ensure that the network of inter-grain contacts is not altered by small perturbations. The texture of this network, set by the preparation of the system, is encoded in ...

A key component of a sediment yield prediction is an estimate of the sediment deposition between erosion sources and a drainage basin outlet. This technical note presents methods requiring a minimum of data which can be used to assess the importance of sediment deposition within the river system of a basin. The methods were applied to a 4123 km basin in the Philippines. Results indicated that s...

In order to study the effect of dust outlet geometry on the performance of cyclone separators, the gas-solid flow characteristics in four cyclone separators with different dust outlet geometries (without dustbin, with dustbin, with dipleg and with dustbin plus dipleg) have been computationally simulated. The gas flow fields were simulated with Reynolds Stress Model(RSM).The effect of instantane...

As a result of designing an energy absorber in the zone conjugation water outlet structures low-pressure and mediumpressure reservoirs, stilling basin is not only under influence vertical hydrodynamic pressure with variable value but also disappearance stagnation can be affected by stress arising from force horizontal absorber. The hydraulic jump pool junction one simplest absorbers. To increas...

The effect of pulsatile pulmonary flow after the modified Fontan procedure was examined in a model that simulated the right heart. An inlet overflow tank (preload), axial pulsatile pump, Wind-Kessel model (afterload), and an outlet overflow tank were connected in series. The standard conditions were flow 2.00 l/min with 12 mm Hg preload pressure, 3.0 Wood units resistance, and an outlet overflo...

PURPOSE Impacts on hemolysis and backflow using a non-occlusive setting with the Better-Header (BH) roller pump were investigated. METHODS AND RESULTS Pump flow of a non-occlusion setting was measured with a pump speed of 3 L/min and 5 L/min against various after-loads. With the non-occlusive setting (BH-NO350), backflow was less than 10% if the pump pressure head was <300 mmHg. When the outl...
