welding produces residual stresses and distortion, having detrimental effect on structure integrity and service performance of the welded pipe joints. this paper investigates residual stresses and distortion during gas metal arc welding (gmaw) of pipes of schedule 40 and 60, nominal diameter 100mm and 200mm and thickness 8mm and 10mm with ansi flanges of class 300#. welding parameters including...

this study was carried out to determine effects of phosphorus residual applied to wheat on vetch (vicia panonioca) growth, yields and some  soil  physical, chemical  properties in soil. the experiment was conducted with randomized completely block design in a field with three replications including four levels of p residual (applied for wheat p0, p15, p30, and p45 kg p2o5 in hectare) from tripl...

A sensor network is made up of a large number of sensors with limited energy. Sensors collect environmental data then send them to the sink. Energy efficiency and thereby increasing the lifetime of sensor networks is important. Direct transfer of the data from each node to the central station will increase energy consumption. Previous research has shown that the organization of nodes in cluster...

conclusions we conclude that volume of residual pneumoperitoneum is a contributing factor in the etiology of postoperative pain after laparoscopic cholecystectomy. results at the end of the study, 17 patients (30.9%) had no residual pneumoperitoneum after 24 hours; which 23 (41.81%) had mild residual pneumoperitoneum, eight (14.54%) had moderate pneumoperitoneum and seven (12.72%) had severe pn...
