State-specific boundary conditions for nonequilibrium gas flows in slip regime.

Boundary conditions for fluid-dynamic variables of strongly nonequilibrium multicomponent gas mixture flows in slip regime are derived systematically by two different approaches. The flow is described in the framework of the state-to-state model for coupled detailed vibrational and chemical kinetics. The specular-diffusive model is applied for particles interaction with the solid wall, and the surface is assumed to be partially catalytic with possible state-specific chemical reactions and vibrational energy transitions described by a simple model based on the analogy with recombination coefficients.

[Cholera in Kazan. Organization and implementation of cholera control interventions].

Data on emergent epidemiological analysis of the cholera outbreak in Kazan are presented. A version of the cholera focus emergence was confirmed, namely water route of transmission as a result of bathing in a water reservoir where sewage waters had penetrated. The outbreak had local and acute character.
