background and objective: our aim was to evaluate the prevalence and population ratio of violence in our center which is one of the tertiary referral centers of trauma in tehran. we also aimed to evaluate the motiva-tions of the struggle, the instrument used, and the type of injuries in the patients who had referred to us after a struggle. methods: in this cross-sectional retrospective study, a...

background: evaluation of intra-city roads in terms of environmental factors of motor vehicle injuries can help us to better identify these factors and the share of each of the factors in injuries. therefore, this study was conducted to determine the high injury areas and the risk factors of motor vehicle crashes resulting in injury and death in tehran, the capital city of iran, from november 2...

In order to describe the characteristics of traumatic brain injury (TEC) in children seen at the Cayetano Heredia National Hospital from 2004 to 2011, a case study was conducted. 316, 14 year-old minors were included, the median age was 4 ± 3 years old. 63.9% were male. The main causes of TEC were falls (80.1%) and car accidents (10.4%). 42.4% (134/316) occurred in the afternoon. There was a hi...

Below is a discussion of an FDA-approved noninvasive Functional Electrical Stimulation (FES) System for ambulation by traumatic T1 to T12 paraplegics having no sensation and no motor function below their spinal cord injury (SCI). The system’s ambulation training, its ambulation performance evaluation and its medical evaluation are summarized.

PURPOSE Electric field stimulation can interact with brain activity in a subthreshold manner. Electric fields have been previously adaptively applied to control seizures in vitro. We report the first results from establishing suitable electrode geometries and trajectories, as well as stimulation and recording electronics, to apply this technology in vivo. METHODS Electric field stimulation wa...

the computer simulation program of a practical scale reverse electrodialysis process has been developed based on the program for saline water electrodialysis. the program is applied to compute the performance of an industrial-scale reverse electrodialysis stack (effective membrane area s = 1 m × 1 m = 1 m2, cell pair number n = 300 pairs). the stack operatingconditions are optimized. seawater a...
