an experimental study was carried out on the wake of a cylinder on the back of which a plate is installed parallel to the fluid flow, with different terminal angles, where the reynolds number is 50000. at the end of the plate, blades with the height of 0.25 equal to the cylinder diameter and with 45, 90 and 135 degrees angle from the horizon, are installed where the cylinder diameter is equal t...

conclusion the myocardial grayscale intensity, velocity and displacement can effectively reflect the situation of steiri in patients after cardiac operation, and ti (cvi) has a higher performance in discriminating between patients with and without steiri. background the timely diagnosis of presence or absence of reperfusion injury after cardiac operation is critical for the patient’s outcome. w...

objective(s):high-intensity interval training (hiit) increases energy expenditure and mechanical energy efficiency. although both uncoupling proteins (ucps) and endothelial nitric oxide synthase (enos) affect the mechanical efficiency and antioxidant capacity, their effects are inverse. the aim of this study was to determine whether the alterations of cardiac ucp2, ucp3, and enos mrna expressio...

aim and background: alexithymia is a psychological construct that is prevalent in a wide range of psychiatric and medical disorders. because of its importance in mental and physical health, many surveys today assess the different aspects of alexithymia in clinical and nonclinical populations. the aim of the present study was to investigate the prevalence of alexithymia and compare male and fema...

the paper presents an analysis of both energy intensity and energy demand for the italianindustrial sector. the aim of the paper is twofold: making a decomposition of energy intensity at the aggregate level and modeling energy demand at the firm level. the decomposition of energy intensity shows different patterns for the different sub-sectors in the period of interest. in the micro approach, p...

background & aim: arteriovenous fistula (avf) is one of the inevitable elements in the take care of patients on hemodialysis. pain of avf puncture is a real problem for patients. the purpose of this study was to assess the effect of inhalation of lavender aromatherapy on pain intensity of arteriove-nous fistula puncture in patients on heamodialysis. methods & materials: in this before and after...

background : road runoff is a linear diffuse source of pollution, with very specific pollutant characteristics and ability to discharge into the environment. heavy metal pollution in road runoff has caused widespread concern since the last century. therefore, the purpose of this study was to assess fe, pb, and cd concentrations in surface runoff from regions with high traffic intensity in the c...

intensity is one of the useful information in extract earthquake analyzing of a region; then, preparing a complete dataset of them is necessary for each region. one of the best intensity information of the most historical and several instrumental earthquakes in iran (from year 658 to 1979) was reported in an intensity scale with five degrees. there are also several earthquakes with reported int...

Kerr effect accounts for the change in refractive index of a material with the light intensity and appears in all known optical materials. In this work we analyze Kerr effect in structured superluminal media (e.g some specific types of resonators). We show that Kerr effect in these structures can be cancelled or even reversed (in comparison with the Kerr effect of the material composing the str...

Parity-time-symmetric (-symmetric) optical waveguide couplers offer new possibilities for fast, ultracompact, configurable, all-optical signal processing. Here, we study nonlinear properties of finite-size multimode -symmetric couplers and predict the nonlinear oscillatory dynamics that can be controlled by three parameters: input light intensity, gain and loss amplitude, and input beam profile...
