ABSTRACT
Digital versus analogue X-ray studies in identifying different X-ray symptoms are analyzed; their accuracy, sensitivity, and radiation load on a patient were established. The costs of consumables used at digital and analogue X-ray studies have been calculated. An algorithm for monitoring artificial pneumothorax and pneumoperitoneum has been proposed for patients with destructive pulmonary tuberculosis. A procedure has been developed to determine a commissural process in the pleural cavity by digital X-ray study and X-ray computed tomography. The findings are indicative of the expediency and medicoeconomic effectiveness of digital X-ray study used in the monitoring collapse therapy in patients with destructive pulmonary tuberculosis.

Time-temperature dependence of concentrations of outgasing products of polymers and rubbers was studied. Applying the principle of time-temperature equilibrium, the exposure time for a laboratory rapid study of polymers at 100 degrees C was estimated to be 1 hr for enamels, lacquers and dyes, 1.5 hr for block and sheet polymers, 2.5 hr for sealants and rubbers, and 4 hr for textile materials, measured from the time when the preassigned temperature was achieved. The rapid method can be recommended for preliminary chemical study of polymers at the stage of their laboratory testing.
