Coincidence of them can be missed because the patient is usually asymptomatic or has mild symptoms related to rhabdomyolysis. The development of rhabdomyolysis as a complication of diabetic ketoacidosis is not well understood and only a few clinical studies address the phenomenon. We are reporting, along with a literature review, a 39-year-old male, who presented with diabetic ketoacidosis complicated with rhabdomyolysis and acute kidney injury. To the best of our knowledge, this is the first case reported in the United Arab Emirates. We highlight the syndrome because it is curable with early detection and proper treatment.展开更多

The buildings are designed according to the response spectrum procedure defined in the 2009 International Building Code （IBC＇09）. Two ensembles of ground motion records with 10% and 2% probability of exceedance in 50 years （10/50 and 2/50, respectively） are used. The nonlinear dynamic resPonses to the earthquake records are computed using IDARC-2D. Key seismic design parameters are evaluated; namely, response modification factor （R）, deflection amplification factor （Cd）, system overstrength factor （Ωo）, and response modification factor for ductility （Rd） in addition to inelastic interstory drift. The evaluated seismic design factors are found to significantly depend on the considered ground motion （10/50 versus 2/50）. Consequently, resolution to the controversy of Dubai seismicity is urged. The seismic design factors for the 2/50 records show an increase over their counterparts for the 10/50 records in the range of 200%-400%, except for the D~ factor, which shows a mere 30% increase. Based on the observed trends, perioddependent R and Cd factors are recommended if consistent collapse probability （or collapse prevention performance） in moment frames with varying heights is to be expected.展开更多
