Abstract
An unsteady three-dimensional mathematical model describing processes of convection-diffusion mass transfer of harmful substances and excess heat in the industrial premises with active ventilation is offered. The model takes into account both stationary and mobile sources of pollution and allows to predict air quality of the working area in the premises of the complicated configuration.

Abstract
'Chemical assembly' method of the nanoprecursors multifunctional matrixes which skeleton structure is similar to the structure of a final reaction product is developed. The method is used for the synthesis of various oxide phases on the basis of zirconate-titanate and lead niobate. The method allows to control the structure, size of particles, deficiency of the produced powders, and electrophysical parameters of piezo-ceramics made on their basis. Application prospects of high values of d31 и d33 и Кр as ultrasonic detectors, acoustic-surface waves filters, etc., are shown.

Abstract
Calculation of the vibration and noise spectra in processing box bodies with the ball-point reinforcer and theoretical research results of vibro-acoustic performance of this kind of treatment are presented. Dependences for the vibro-speed and acoustic power levels are detected. It is established that abatement of noise can be achieved only by decreasing the vibrational energy loss factor.
