There is scarce data about prevalence of stroke in Brazil.The National Health Survey (PNS) is a community-based epidemiological survey, with a nationally representative sample to assess the absolute numbers with respective prevalence rates of stroke and post-stroke disabilities.It was estimated 2,231.000 stroke and 568,000 stroke cases with severe
The transmission system is the key components of the helicopter,the study and analysis of the dynamics characteristic and virtual simulation have an important function for the whole life cycle in every stage.The 3D model of the helicopter transmission system is established by CATIA software,the load under the typical working condition is calculated
Blunt carotid artery injury (BCAI) is a rare sequelae of blunt neck trauma.It may lead to stroke and major neurological deficits.Therefore, early diagnosis and management are crucial to prevent or reduce associated morbidity.We report a 22-year-old male who sustained an accidental left BCAI with an air-gun bullet.The injury was suspected on clinica
In this paper, computational fluid dynamic (CFD) analysis and experiments have been carried out to study the effect of nozzle pressure ratio, i.e.the ratio of inlet pressure to atmospheric pressure, and the pitch circle diameter of the control jets to regulate the base pressure.The variables considered for the analysis as well as the experiments ar
