Wounds come in many shapes and sizes often requiring washout and exploration. The limb is prepared and draped in the desired fashion. A large sterile x-ray C-arm cover is placed under the limb and secured proximally with a towel clip. A suction tube is placed in the lowest part. This tube can be cut and dropped into the bag when washout is completed and the bag removed, allowing further procedu...

Intussusception is an invagination of a segment of the gastrointestinal tract into an adjacent one. Jejunojejunal intussusception is a rare complication of jejunostomy tube placement with an incidence of 1%. We are reporting a case of 35-year-old man who was suffering from severe oral, lesions due to Ingestion of acide agents. He received Witzel jejunostomy for early feeding. Ileus developed po...

Jejunojejunal intussusception is a rare complication of jejunostomy, and its preoperative diagnosis and surgical treatment have not been reported. A 78-year-old man suffered from vomiting off and on after emergency exploratory laparotomy with omentoplasty for perforated duodenal ulcer. He also received Witzel jejunostomy for early feeding. Ileus developed postoperatively and plain X-ray of the ...

The present work shows the results obtained from experimental investigations of the augmentation of turbulent flow heat transfer in a horizontal tube by means of mesh inserts with air as the working fluid. Sixteen types of mesh inserts with screen diameters of 22mm, 18mm, 14mm and 10mm for varying distance between the screens of 50mm, 100mm, 150mm and 200mm in the porosity range of 99.73 to 99....

A conical shell-tube design with non-uniform fins was addressed for phase change latent heat thermal energy storage (LHTES). The shell filled nano-enhanced material (NePCM). cone aspect ratio of the and were adopted as geometrical parameters. type volume fraction nanoparticles other investigated alumina, graphite oxide, silver, copper. finite element method employed to solve natural convection ...

The behaviors of bar-reinforced concrete filled steel tubular columns subjected to axial load were studied. One plain concrete filled steel tubular column and three bar-reinforced concrete filled steel tubular columns were tested. The deformation of specimens and the strain of steel tubes were measured. Based on experimental researches, a simple numerical analysis method was presented to simula...

Three-dimensional CFD simulations are carried out to investigate heat transfer and fluid flow characteristics of a four-row plain fin-and-tube heat exchanger using the Commercial Computational Fluid Dynamics Code ANSYS CFX 12.0. Heat transfer and pressure drop characteristics of the heat exchanger are investigated for Reynolds numbers ranging from 400 to 2000. Fluid flow and heat transfer are s...

A 2-day-old baby boy, 38 weeks gestation, weight 2000 g was brought due to hypersalivation and imperforate anus with gasless abdomen on plain X-ray. He underwent a gastrostomy tube insertion and colostomy. In contrast study of the stomach, on the 5th postoperative day, the dye spilled into the tracheo bronchial tree and the catheter was seen, entering the right main bronchus. The patient underw...

The optimization of the louver angle (θ) and the louver pitch (Lp) for a louver finned and tube heat exchanger was investigated numerically along with a simplified conjugate-gradient method (SCGM). The area reduction ratio relative to a plain surface is the objective function to be maximized. A search for the optimum louver angle (θ) and louver pitch (Lp), ranging from 15°< θ < 40° and 2 mm < L...
