We review the properties of classical p-brane solutions to supergravity theories, i.e. solutions that may be interpreted as Poincaré-invariant hyperplanes in space-time. Topics covered include the distinction between elementary/electric and soli-tonic/magnetic solutions, examples of singularity and global structure, relations between mass densities, charge densities and the preservation of unbr...

Data from the first run of the BABAR detector at the PEP II accelerator are presented. Measurements of many rare B decay modes are now possible using the large data sets currently being collected by BABAR. An overview of analysis techniques and results on data collected in 2000 are described.

متن کاملGenotoxicity and mutagenicity of Echinodorus macrophyllus (chapéu-de-couro) extracts
Echinodorus macrophyllus, commonly known as chapéu-de-couro, is a medicinal plant used in folk medicine to treat inflammation and rheumatic diseases. In this work, we used short-term bacterial assays based on the induction of SOS functions to examine the genotoxicity and mutagenicity of an aqueous extract of E. macrophyllus leaves. Whole extract and an ethyl acetate fraction showed similar geno...
متن کاملThe Imperial Animal
scriptions of genital and sexual development are clear and thorough. However, his description of the various genetic and hormonal factors involved in sexual development is skimpy and very difficult to follow. For example, Jost's classic experiments on the factors involved in determining sex and internal and external genital development are hardly mentioned, and certainly not dealt with in a way...
