the quantitative analysis of cardiac motions in echocardiography images is a noteworthy issue in processing of these images. cardiac motions can be estimated by optical flow (of) computation in different regions of image which is based on the assumption that the intensity of a moving pattern remains constant in consecutive frames. however, in echocardiographic sequences this assumption may be v...
Introduction: Cardiotoxicity is an unavoidable complication after chemotherapy. The present study investigated the effect of 12 weeks of aerobic exercise (high-intensity interval training or moderate-intensity continuous training) with and without blood flow restriction on some anthropometric indices in women with breast cancer who had chemotherapy-induced cardiotoxicity. Methods: Twenty breas...
Background and Aim: Conducting exercises with various methods can have different effects on the body tissue. The purpose of this study is to evaluate the effects of one session of resistance training with high and low intensities, while both restricting and not restricting the blood flow, on the levels of irisin and glycerol serum in trained male subjects. Methods: This quasi-experimental study...
in this paper, considering the importance of incoming flow turbulence intensity into combustion chamber, tripping wire effect on the flow wake has been experimentally investigated within a linear compressor cascade. to do this, two wires were implemented along each blade and their effects on average velocity, turbulence intensity and vortices frequencies at reynolds number 45500 were accurately...
Background and Aims: Physical activity and blood flow restriction (BFR) training can affect bone metabolism. This study aimed to investigate the effect of a plyometric exercise session with and without blood flow restriction on bone metabolism markers, such as bone alkaline phosphatase (BALP) and C-terminal telopeptide of type 1collagen (CTX), as the markers of bone formation and destruction, ...
the efficiency of a collar in reducing the scour depth around circular and rectangular piers is studied at different flow intensities (ratio of upstream shear stress to sediment critical shear stress). rectangular piers aligned with the flow as well as skewed at 5º, 10º, 20º were examined. previous studies had shown that with collar the equilibrium time of scouring increases considerably. to re...
in this study, changes in speed and turbulence intensity in the wake of a peugeot model and the drag coefficient changes with increases vehicle speed in unsteady flow measured and evaluated. the blow open circuit wind tunnel to simulate fluid flow is used. disturbances and nominal maximum speed of the device, respectively is, 30 m / s and 0.01%. has been continuously increasing speed by an inve...
background: this cross sectional comparative study was performed to compare the mean fluorescence intensity of cluster of differentiation 45 between healthy individuals and patients with acute lymphoblastic leukemia. patients and methods: thirty three healthy individuals (mean age 11 years) and 41 patients with b cell acute lymphoblastic leukemia (mean age 7 years) were enrolled in the study in...
