Use of biocompatible calcium-phosphate glass ceramic BGC in surgical treatment of maxillary cysts

The possibility of using the granulated form of biocompatible material made of calcium-phosphate glass ceramic BGC for treatment of maxillary cysts was demonstrated.     

Determination of the melting point of ice in porous glass in relation to the size of the pores

The method of proton magnetic resonance is used to determine the melting point of ice particles in the pores of monodisperse porous glasses ranging from 10 to 1000 Å in radius.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 48, No. 3, pp. 461–466, March, 1985.     

Physical modeling of urban air-pollutant transport

Air-pollutant transport within an urban setting is conditioned by local urban geometry, urban-modified meteorological variables, a wide variety of source characteristics and local topography. Extreme complexity and local specificity of the resulting dispersion process requires the use of physical modeling rather than numerical or analytical methods to predict concentration distributions. Serving as an analog computer the boundary-layer wind tunnel provides reliable concentration data which can be applied directly to design and/or decision making.A brief review is made of similarity criteria for simulating physical modeling of the atmospheric boundary-layer and source characteristics in a boundary-layer wind tunnel. Applications to several problems related to stack, vent and automobile emissions are described. Rudimentary portions of a data bank are presented which, with additional data acquisition, can provide a practical method for prediction of automobile exhaust concentrations that will result from proposed freeways or alternative traffic routings.     

Convergence

Convergence is the idea of merging the duties and responsibilities of physical security with that of digital security to make them part of a common reporting structure--to employ tools and techniques that are parallel if not collinear.
