Experimental and numerical analyses of the hemodynamics impact on real intracra...
Souza, A.; Lopes, D.; Souza, S.; Ribeiro, J.; Lima, R. A.; Ferrera, C.This study investigates the impact of hemodynamics on real intracranial aneurysms (IAs) using experiments and computational fluid dynamics (CFD) simulations. A particle tracking velocimetry (PTV) approach was used to study the vortical structures inside a real aneurysm and validate numerical simulations performed at a steady regime for different flow rates. Moreover, this and two additional patient-specific cas...
Artery stenosis of the renal graft : experience of a center of northeastern Brazil
Nasserala, Jarinne Camilo Landim; Oliveira, Cláudia Maria Costa; Cerqueira, João Batista Gadelha de; Souza, S.; Silva, S. L.; Santos, L. C. D. O.Background. Transplant renal artery stenosis (TRAS), the most common vascular complication after transplant (Tx), leads to resistant hypertension, impaired renal function, and even loss of the graft. The purpose of the study was to investigate the prevalence and factors associated with TRAS in northeastern Brazil. Methods. The study was conducted as a retrospective case-control study in a population of Tx recip...
Student bystander behavior and cultural issues in cyberbullying: when actions s...
Costa Ferreira, P. A. N.; Veiga Simão, A. M.; Ferreira, A.; Souza, S.; Francisco, S.This study aims to investigate whether student bystander interventions can influence the relationship between being a bystander of a cyberbullying incident and being the victim or the aggressor. Another aim is to understand the specific behavior presented by students bystanders, namely whether they noticed incidents of cyberbullying and interpreted these events as an emergency and which actions they determined ...
