A fully automatic anemometer calibrator intended for performing fast and accurate calibrations has been developed to fulfil the increasing demand and strict requirements of the wind energy industry. Different sensors are connected to a computer where a virtual environment acquires and processes the incoming signals and controls a wind tunnel, allowing the calibration of the anemometer at the pr...

BACKGROUND AND PURPOSE Pretreatment diagnosis for the location of shunts and arterial feeders of spinal arteriovenous fistulas is crucial. This study aimed to evaluate the utility of subtracted CT angiography imaging by using nonrigid registration (R-CTA) in patients with spinal arteriovenous fistulas compared with conventional CTA imaging. MATERIALS AND METHODS The records of 15 consecutive ...

Thin films made of a polymer (cellulose triacetate, CTA) and plasticizer have been studied as novel sorptive phases for chlorpyrifos, triclosan tonalide. The preparation is reproducible only requires the to be added into an organic dispersion containing CTA. evaporation solvent leaves easy manipulate continuous homogeneous thin film, which has investigated in terms both composition extraction e...

Abstract The work is devoted to the development of a new experimental method for entering controlled disturbances with given frequency-wave structure into supersonic boundary layer. Experimental data on formation from two pulsed sources (pulsed glow discharge) in laminar flat-plate layer at Mach number equal 2 are given. experiments were carried out T-325 wind tunnel ITAM SB RAS. localized spac...

Triaxial sonic anemometer velocity and temperature measurements were used to investigate the local structure of the velocity and temperature fluctuations in the unstable atmospheric surface layer above a grass-covered forest clearing. Despite the existence of a 2/3 power law in the longitudinal velocity (2 decades) and temperature (1 decade) structure functions, local isotropy within the inerti...

BACKGROUND AND AIM The role of computed tomography angiography (CTA) on the management of acute overt obscure gastrointestinal bleeding (OGIB) remains unclear. We designed a study to evaluate the impact of CTA before enteroscopy for acute overt OGIB. METHODS All patients undergoing CTA followed by enteroscopy for acute overt OGIB were enrolled in this retrospective study. Clinical characteris...
