OBJECTIVE To find out various modes of benign prostate hyperplasia (BPH) presentation in our region and their relation to postoperative failure to void after transurethral resection of prostate (TURP). METHODS A study was conducted at Urology Department, Sandeman Teaching Hospital Quetta and Akram Hospital (Private) Quetta from January 2000 to December 2003. All BPH patients in whom the prima...

A multi-scale methodology that includes microscale finite element simulations, physical experiments, and a macroscale phenomenological model was used to determine the appropriate first-order influence parameters relating to void/ crack nucleation. The finite element analyses were used to examine the role of seven independent features (number of silicon particle sites, uniformity of particle siz...

We apply the HotQC method of Kulkarni et al. (J Mech Phys Solids 56:1417–1449, 2008) to the study of quasistatic void growth in copper single crystals at finite temperature under triaxial expansion. The void is strained to 30% deformation at initial temperatures and nominal strain rates ranging from 150 to 600K and from 2.5×105 to 2.5×1011 s−1, respectively. The interatomic potential used in th...

The stress and displacement fields are determined inside and outside a circular inclusion located in the vicinity of a circular void in an infinite elastic solid, within a circular cylinder, or near the free surface of a half-space, in the case when the inclusion is characterized by a uniform eigenstrain of the antiplane shear type. The fields are obtained as the sum of their infinite-medium st...

OBJECTIVE The aim of the study was to determine the effect of massage to the sacral region after cesarean delivery instead of employing a urinary catheter for the prevention of urinary retention. STUDY DESIGN Cross sectional study. MATERIAL AND METHODS This interventional study population consisted of 60 women who were divided into two intervention groups and one control group. For the firs...

nowadays, quality control of bread, especially in large scale production, requires application of novel methods. in this research, image analysis of digital images of barbary bread enriched with soy flour was carried out at two storage intervals. using imagej software, crumb features (mean cell area and void fraction) were computed for each image. fractal dimensions of bread crumb images were m...

in this paper, direct numerical simulation of two-phase incompressible gas-liquid flow for simulation of bubble motion in a microtube is presented. microtube radius is 10 µm. the interface is tracked using volume of fluid (vof) method with continuous surface force (csf) model. the flow is solved using a finite volume scheme, based on piso algorithm. numerical simulation is performed on a axisym...

We study the behaviour of spherical Voids in Lagrangian perturbation theories L(n), of which the Zel’dovich approximation is the lowest order solution L(1). We find that at early times higher order L(n) give an increasingly accurate picture of Void expansion. However at late times particle trajectories in L(2) begin to turnaround and converge leading to the contraction of a Void, a sign of path...

Abstract: Rainfall runoff collection in ephemeral streams is an objective in semi-arid zones. Rack intake systems are proposed to collect these flash floods with intensive sediment transport. The design parameters address the problem of clogging the spacing between bars. Experiments for two different void ratio racks are shown. Flows, longitudinal slopes in the rack, and water with three gravel...
