Mathematical model for calculating the heating of glass-kremnezit material

Abstract: A technology and a facility for cost-effective fabrication of glass-kremnezit based on modular production methods have been developed. A mathematical model is proposed for calculating heat transfer. This model makes it possible to determine the required thicknesses of the thermal insulation for the covered heater and the shapes for which the heat losses into the surrounding atmosphere during continual operation of the heater are reduced to a minimum.

Analysis of the efficiency of external carotid surgery.

Abstract: The authors confirmed efficacy of external carotid artery plasty in occlusion of the internal carotid artery. The findings of triplex scanning and transcranial dopplerography demonstrated a considerable increment in the blood flow through the middle cerebral artery in the operated zone, amounting to approximately 30% one year after surgical treatment. Twenty-two patients before and after surgery were subjected to single-photon emission computed tomography. The majority of patients after surgery were found to have improved perfusion of the previously ischaemized zone of the brain on the side of operation according to the data of single-photon emission computed tomography.

Probabilistic Prediction of Residual Operating Life of Measurement Equipment Using Results of Parametric Monitoring

Abstract: The problem of probabilistic prediction of residual operating life of measurement equipment with parametric failures is investigated. A general analytical solution of the problem with an arbitrary finite number of defining parameters is presented. The obtained solution is applied to a practical example.

Utilization of Cr(VI) solutions with steel shavings

Abstract: New single-stage method was developed for chemical utilization of wastewater containing 0.25 to 400 g L–1 of chromium in terms of chromium anhydride with the us of sulfuric acid and steel cuttings. The method makes it possible to convert hexavalent chromium into easily used ferrochromium precipitates. It was found that there occur periodic synchronous concentration fluctuations of Cr(VI) and Cr(III) up to, respectively, 400 g L–1 and 150 mg L–1 in the course of reduction of hexavalent chromium with the use of steel cuttings in sulfuric acid solutions.
