Abstract: Introduction: Urinary incontinence after radical prostatectomy is a major complication with profound impact on the social life of the patients. we report inicial cases of patients treated with male sling implant. Methods: Eight patients with urinary incontinence after radical prostatectomy underwent to male sling (Argus-T® - Promedon) implant. We analyzed the age, the number of transurethral resection previously of the implant, the degree of incontinence before the sling (by urodynamics) and the subjective satisfaction with the surgery by telephone. Results: The patients (08) were submitted to a radical retropubic prostatectomy for localized prostate cancer. All incontinent patients developed stenosis of vesico-urethral anastomosis and were underwent transurethral resection of the anastomotic fibrosis (ranging from one to three procedures). Five patients had moderate to severe urinary incontinence before the procedures. After the implant, five pa-tients had no improvement in the degree of incontinence, three patients had a subjective improvement, two of them were completely dry. These, previously, had the lowest degree of incontinence in the objective analysis (urodynamics). Conclu-sion: The urinary incontinence after prostatectomy is a morbidity with challenging treatment. The male sling is a good method for mild cases and motivated patients, not being the first choice for more severe cases.

Abstract: Main objective of this study is to compare and assimilate the digital elevation models (DEMs) generated using C-band Envisat, L-band ALOS PALSAR Interferometric SAR (InSAR) datasets and Cartosat-1 optical stereo data. The study area is Dehradun city and surroundings including lower Shivalik hills i.e. the younger Himalayas in the south and higher Himalayas on the north. The general elevation of the area ranges from 400m to 2000m AMSL. Ground control points (GCPs) collected from Differential Global Positioning System (DGPS) survey, were used for satellite triangulation of optical data & geocoding of InSAR data. RMSE for satellite triangulation for cartosat-1 is 0.745 using 6 ground control points and 3 check points. It is found that when GCP’s are used along with reference DEM (SRTM), the DSM generated by ALOS PALSAR and DSM generated from Cartosat-1 stereo data are well representing the terrain. The fusion of imagery from multiple sensors has been in use in remote sensing for scientific exploration in the past but there is a little work done on data fusion application for generation of topography (DEM) through Optical stereo and SAR interferometry data sources. The defined framework for data fusion uses three fundamental steps in the analysis of the system namely, identification, estimation, and validation for algorithm preparation. The knowledge of the study area, i.e. the field, and the processes involved in the DEM generation of optical and InSAR data are cognitively used for rule-based decision making in the algorithm for mathematical generation of resultant DEM through data fusion implemented at feature level.

Abstract: For many years, sand has been predominantly used as fine aggregate in civil engineering construction. More recently, the source of quality sand has been fast diminishing resulting in ever increasing cost of construction. Laterite is now seen as a possible replacement for sand in concrete mix. This paper presents the results of the laboratory tests carried out to investigate the ultimate strength behaviour of laterised concrete. Five classes of specimens incorporating 0, 10, 20, 30, and 40% laterite as replacement by weight of sand were prepared. For each specimen class, reinforcement was varied using 2, 3, 4, and 5 numbers of 10 mm high yield bars as tensile reinforcement- with minimum shear provision, at 300 mm centers. When subjected to compressive tests using Avery Denison Universal Testing Machine, the compressive strength of normal concrete beam specimens ranges between 17.48 N/mm2 and 20.39 N/mm2 while that of laterised concrete ranges between 15.29 N/mm2 and 35.69 N/mm2. The analyses showed that laterised concrete beam specimens give satisfactory performance compare to normal concrete beam specimens when the content of laterite in the concrete as partial replacement for sand does not exceed 25%. This result supports the earlier findings that laterised concrete beams can be a satisfactory substitute for normal concrete in building construction.
