gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
The purpose of the study was to compare tubing-related injuries to wakeboarding- and water skiing-related injuries. Data was collected from the 2000-2007 National Electronic Injury Surveillance Survey for 1,761 individuals seeking care at an emergency department due to a tubing-, wakeboarding, or water skiing-related injury. Data included patient age and sex, as well as injury characteristics i...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
Rowing injuries have been attributed to poor technique, suggesting a need to understand the mechanics of rowing and the influence on technique of different training regimes and ergometers. The aims of this study were to investigate the repeatability of the kinematics of the lumbopelvic region during rowing and to compare these kinematics between rowing on two different ergometers. An electromag...
Tournament water skiing is an increasingly popular and internationally successful sport in Great Britain, despite the climate. The kinematics and injury patterns of the three disciplines will be unfamiliar to most clinicians and are described, with estimation of the stresses. Advances in equipment over the last 15 years have reduced the risk of severe injury in the tricks event, while high spee...
Rowing is a physiologically intense sport which requires consistent and economically efficient strokes. Therefore, the muscles synergy is crucial to determine success in rowing either on ergometer or water. However, there is no studies have been done comparing the muscle synergy during rowing with and without slides system. Thus, the purpose of this study is to evaluate the muscle synergies dur...
A high performance seating unit has been produced for a water-skier with bilateral transfemoral amputations. The system, in which the user sits whilst skiing, has helped the client to further her sporting career and enabled her to compete successfully at the highest levels of disabled water-skiing competition.
In this paper we present an instrumentation system which integrates inertial motion sensing and mobile computing technologies to acquire sensory information during on-water rowing. The use of miniaturized piezoelectric gyros is proposed and tested to sense the oar rotation. By time-integrating the gyro output signal, the pitch angle, namely the angle the blade is away from perpendicular to the ...
Data fusion of relative movement in fast, repetitive-action sports using body wireless area networks
Rowing is an intensive, all-body sport, where bad technique can lead to injury. Crew cohesion, particularly timing, is vital to the performance of the boat. The coaching process, and injury prevention, could be enhanced if data relating to the movement of the oarsmen could be collected, without hindrance to the oarsmen, during on-water training. Literature until recently has concentrated upon b...
