BACKGROUND AND OBJECTIVES Although there have been so many reports of catheter ablation of atrial fibrillation (AF) with magnetic navigation system (MNS), it is not necessarily obvious that MNS is more effective than conventional ablation. We performed AF ablation with MNS and compared the clinical outcomes and radiofrequency ablation parameters with those of conventional ablation. SUBJECTS A...
Statement of Problem: Computed tomography (CT) has proved to be the most precise method to evaluate the quantity of jaw bones.In recent years, patient dose which is much more greater in CT than conventional methods has attracted more attention, and has brought the idea of using the conventional method in more accurate ways or applying new methods with lower doses.Purpose:radiovisiography for pr...
improving cleaning and disinfection performance must be taken into account for prevention and control of infection. health care settings are engaged in a battle against healthcare associated infection (hais). the importance of infection prevention and control is increasing due to rapidly developing strains of multi-drug resistant organisms (mdros) that can result in serious illness and even dea...
Ru/Al2O3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of RuCl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. The samples were characterized by TEM, XRD and TPR techniques. The catalytic performance tests were carried out in a fixed-bed micro-reactor under diffe...
Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...
Electronic learning introduces a teaching device for deeper and more efficient learning. A study was conducted by the Pathology Department of Tehran University of Medical Sciences, Tehran, Iran. The topic of practical pathology was selected earlier based on the curriculum. High-quality digital images of the slides were presented in the form of an e-file. The medical students were asked to regis...
