The Beckenstein-Hawking black hole entropy in string theory and its generalizations, as expressed in terms of charges that correspond to central extensions of the supersymmetry algebra, has more symmetries than U-duality. It is invariant under transformations of the charges, involving a 12th (or 13th) “dimension”. This is an indication that the secret theory behind string theory has a superalge...

Mixing of air containing small water droplets is investigated in the laboratory model to elucidate smallest scales of air entrainment and mixing in real clouds. Particle Image Velocimetry (PIV) is applied to evaluate turbulent characteristics of the flow field generated in the cloud chamber by buoyancy of the introduced mist. It permits to investigate dynamics of the process for scales from 0.0...

The rat fibroblast cell line Rat 1 was transfected with total DNA of a gastrocarcinoma cell line, BGC-823. The transforming gene was cloned from the genomic library of the secondary transformants using in situ hybridization with a probe of the human Alu repeat sequence. This cloned gene is homologous to the protooncogene c-Ha-ras. The activation lesion of the transforming gene was identified by...
