INTRODUCTION We report the incidence, distribution, etiology, and outcome of the urogenital trauma in 8 major cities of Iran according to the database of national trauma project. MATERIALS AND METHODS Between 2000 and 2004, we prospectively collected the data of all the traumatic patients hospitalized for more than 24 hours in 8 cities (Tehran, Mashad, Ahwaz, Shiraz, Tabriz, Qom, Kermanshah, ...

We analyze pattern formation in doubly resonant intracavity second-harmonic generation in the presence of competing nondegenerate parametric downconversion. We show that for positive cavity detuning of the fundamental frequency the threshold for parametric oscillation is lower than that of transverse, pattern forming instabilities. The parametric oscillation strongly modifies the pattern dynami...

introduction: today sport is one of the important social criterion and athletes are trying to be a champion. therefore, there is an increase in misuse of doping agents especially anabolic-androgenic steroid. this study was carried out to determine the prevalence of the doping agents' abuse among male bodybuilders' and to access their knowledge about their side effects in kermanshah gymnasiums i...

We investigate the impact of cyclic competition on pattern formation in the rock-paper-scissors game. By separately considering random and prepared initial conditions, we observe a critical influence of the competition rate p on the stability of spiral waves and on the emergence of biodiversity. In particular, while increasing values of p promote biodiversity, they may act detrimentally on spat...

We present a comprehensive study of pattern formation in single-field relaxational systems with field-dependent coefficients. A modulated mean-field theory leads to a form amenable to analysis via the geometric architecture developed in our earlier work for systems that exhibit phase transitions between global steady states [Phys. Rev. E 69, 011102 (2004)]. We demonstrate that the phase diagram...

introduction: kawasaki disease is a systemic vasculitis that usually involves children younger than 5 years old. etiology is unknown and since there is no labaratory test to diagnose kawasaki disease, the major diagnosis is based on clinical findings .the objective of this study was to determine incidence, complications, time of treatment and clinical manifestations in children with kawasaki di...
