ОЭЗ как фактор ускоренного экономического роста региональной экономики (на примере АО «Особая экономическая зона технико-внедренческого типа «Томск»)

Выявлены основные проблемы функционирования особых экономических зон и рассмотрены перспективы развития ОЭЗ ТВТ "Томск".The main problems of the functioning of special economic zones are identified and the prospects of development into special economic zones of the technical-innovative type "Tomsk" are considered

Mathematical model of stacked one-sided arrangement of the burners

Paper is aimed at computer simulation of the turbulent methane-air combustion in upgraded U-shaped boiler unit. To reduce the temperature in the flame and hence NOx release every burner output was reduced, but the number of the burners was increased. The subject of studying: complex of characteristics with space-time fields in the upgraded steam boiler E-370 with natural circulation. The flare structure, temperature and concentrations were determined computationally

Ultrasonography of the larynx for diagnosis of the vocal folds mobility impairment

Purpose. To study a possibility of performance and diagnostic accuracy of ultrasonography (US) of a larynx in identification of motility disorders of VF (vocal folds) in comparison with the laryngoscope which is traditionally applied for this purpose. Materials and methods. According to the objectives of the study, two patient groups were formed. In first group of patients (n = 466) we studied acceptability of ultrasonografy to discriminate various laryngeal structures. In second group of patient (n = 432) we evaluated the diagnostic accuracy of ultrasonography in point of detection of vocal muscles paresis. Results. Laryngeal structures were available to examination by ultrasound (without taking in account age and sex) in 92.7% of patients. Two patterns have been identified in the course of this part of the study: deterioration of visibility of the vocal folds with increasing patient age and better visibility of the vocal folds in women than in men. According to the comparative analysis, ultrasonography accuracy rate (in those patients who had had clearly visible vocal folds during ultrasonography) did not differ from that during videolaryngoscopy. Conclusion. During the conducted research it was found that the US of the larynx is an effective and perspective method for detection of a paresis of VF with sensitivity and specificity 93,55% and 100% respectively. Among those patients whoapos; VF are available to ultrasound evaluation the accuracy of method is comparable with a videolaryngoscopy and can be used with success in daily work of units of endocrine surgery
