Event horizon as alternative to cosmological singularity

The general relativistic equations for a homogeneous istoropic metric of the most general form are considered. It is concluded that an event horizon is a possible alternative to a cosmological singularity for “usual” matter. This conclusion is illustrated by the case of a flat spatial universe.     

Reaction of tetrafluorobenzobarrelene and tetrafluorobenzodihydrobarrelene with nitrosyl chloride

Conclusions Reactions of tetrafluorobenzobarrelene and tetrafluorobenzodihydrobarrelene with nitrosyl chloride were studied. It was shown that during attack at the sp²-hybridized carbon atom the exo-direction is more accessible sterically in the first case and the endo-direction is more accessible in the second.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 679–681, March, 1976.     

τ-Pseudocompact Mappings

We consider the problem of extending the notion of -pseudocompactness from spaces to continuous mappings, obtain conditions under which the product of -pseudocompact mappings is -pseudocompact. Since any space X can be considered as a continuous mapping from X into a singleton, we obtain consequences of the theorems on multiplicativity of -pseudocompactness for spaces. Thus, we study the notion of -pseudocompact mapping and some its properties similar to those of a pseudocompact space as well as consequences of the obtained assertions for spaces.     

Singular Integral Equations on Non-Smooth Curves in Hölder–Frechét Space

We consider singular integral equations on non-smooth rectifiable curves and on certain classes of curves of infinite length.     

Stabilized phospholipid dispersions based on organosilicon amphiphiles

Cerasome-forming amphiphile based on L-aspartic acid dihexadecyl ester derivative with (3-aminopropyl) triethoxysilane moiety in its structure was synthesized. Mixed storage-stable lipid dispersions containing phosphatidylcholine were prepared and their properties were examined.
