[Species composition and microbial contamination of atmospheric humidity condensate and potable water from the Mir water supply systems during Mir main missions 4 through 27].

Analyzed were quantitative and qualitative characteristics, and processes of formation and transformation of microflora in the atmospheric humidity condensate (AHC) and potable water (PW) regenerated from the condensate by the long-operating system (SRV-K) aboard space station Mir. The paper presents data on species composition of microflora of AHC, and PW regenerated by SRV-K in the period from 1989 through to 1999. The following microbial species were identified in AHC: Alcaligenes (14.

[A comparative study of sun-protective glasses for locomotive team workers].

Solar flashes of 1500 to 9000 kd/m2 have been ascertained to have an adverse impact on the functional status of a visual analyzer. Comparing Russian and foreign sun-proof filters has indicated that a HC-9 neutral light-proof filter and a NIIOOIK film have the optimum light-protective properties, which may be recommended for use in the sun-proof glasses for locomotive workers.

[The development of methodology, means and device for quick detection of aquatic bacteria in water supply systems of spacecrafts].

Microbial contamination is one of the major characteristics of potable water. The authors give data illustrating occurrence of various microbial species in the inlet products of the water regeneration and supply systems aboard spacecraft. Cultural/biochemical techniques of microbial monitoring (TMM) seem to have the best outlook for potable water assessment in space flight.
