PURPOSE The aim of this retrospective study was to evaluate the rate of recurrence and incontinence after the treatment of fistulae or fistulous abscesses by using the staged drainage seton method. METHODS According to the condition, a drainage seton alone or a drainage seton combined with internal opening (IO) closure and relocation of the seton was used. After a period of time, the seton wa...

this paper aims to assess the quality and accuracy aster dems and the arcgis alogorthms used for hydrologic analyses. to this end, first the plan of drainage networks in the region was extracted from aerial photographs and high resolution satellite images and was set as the real ground. in the next step, using the hydrology tool in arcgis software, raster networks of the region for the whole ca...

In agricultural lands, high nutrient levels of nitrogen, phosphorus and potassium are very important due to the high need of plants. By improving the nutrient content of sodium soils, the fertility and growth of the plants improve. Accordingly, in order to investigate the effect of underground drainage on soil quality in Khuzestan region, this experiment was carried out in a completely randomiz...

The results of an experimental investigation of kerbside bridge deck drainage units are presented. The conveyance capacity, resistance coefficients and sediment transporting efficiencies of different types of drainage unit used in shallow bridge drainage decks are examined over a range of bed gradients likely to be encountered in practice. The use of a V-shaped cross section is shown to be part...
