We are interested in the numerical modeling of wave-current interactions around beaches’ surf zones. Any model to predict the onset of wave breaking at the breaker line needs to capture both the nonlinearity of the wave and its dispersion. We have formulated the Hamiltonian dynamics of a new water wave model. This model incorporates both the shallow water(More)
Wave action, particularly during storms, drives the evolution of beaches. Beach evolution by non-linear breaking waves is poorly understood due to its three-dimensional character, the range of scales involved, and our limited understanding of particle-wave interactions. We show how a novel, three-phase extension to the classic “Hele-Shaw” laboratory(More)

A cryptic plasmid from a soil strain of Bacillus subtilis was found to contain a sequence having features of IS element. Homologous sequences were also found in the chromosome of this strain and in the chromosomes of some other B. subtilis strains.
Two fragments of conjugative plasmid p19 (95 kb) from the soil strain Bacillus subtilis 19 were cloned and sequenced; these fragments carry genes, products of which are indispensable for the conjugative transfer. One of the fragments 4518 bp in size carries five open reading frames and their fragments (ORF1-ORF5). The protein corresponding to ORF4 is(More)
Methods The naïve human ScFv antibody library expressed on the M13 surface was created using total RNA from lymphocytes of 20 HIV-1 subtype A infected Russian patients. Standard RT with random hexanucleotide oligos, cDNA matrix heavy and light repertoires PCR-amplification, ScFv genes PCR assembly and pCANTAB5E phagemid cloning were used. HIV-1-specific(More)
The Bacillus subtilis 1387 soil strain, which contains three cryptic plasmids simultaneously, was described. Two small plasmids (6.3 and 8.5 kb) were homologous to each other, and a large plasmid (30 kb) had no homology with them. The plasmids were separately transmitted into cells of the Bac. subtilis 168 strain, and some plasmid characteristics were(More)
