conclusions although skin traction had no effect on analgesic consumption, it significantly decreased the pain at the end of the first day. the application of skin traction in patients with intertrochanteric fractures is recommended. results the severity of pain was significantly decreased in skin traction group only at the end of the first day after traction application (2.7 ± 0.8 vs. 3.3 ± 0....

Analog circuits are essential in everyday life and electrical engineering [...]

due to the expected increase of defects in circuits based on deep submicron technologies, reliability has become an important design criterion. although different approaches have been developed to estimate reliability in digital circuits and some measuring concepts have been separately presented to reveal the quality of analog circuit reliability in the literature, there is a gap to estimate re...
