Hydrodynamic characteristics of the capsular polysaccharides ofKlebsiella

Investigations of the acidic polysaccharides isolated from the capsules ofK. scleromatis andK. ozaenae under the conditions of high-speed sedimentation and an approximation to equilibrium (Archibald's method) has made it possible to regard them as polydisperse homogeneous substances with different molecular masses and a nonspherical form of the molecules entering their composition.     

Laser atomic emission analysis of airborne pollution of green stands by deicing agents

We present the results of analysis of airborne pollution of green stands along the Minsk Beltway by components of deicing agents (chlorine). We used laser spectral analysis for rapid determination of chlorine. Comparison of the analysis results for accumulation of salt components in samples collected from trees along the Minsk Beltway with control samples showed that the chlorine content is 3.7–5.5 times higher than the control values. The degree of pollution depends on the position of the trees on the forest edge relative to the highway, which is confirmed by reliable correlation coefficients.     

Inhibition of radiation-chemical oxidation of n-octane by stable iminoxyl biradicals

Conclusions The biradicals are effective inhibitors, their inhibiting action increasing with an increase in the distance between the fragments.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 45–48, January, 1977.
