Plasmids and transposable elements in Salmonella wien.

The plasmids from six clinical strains of Salmonella wien have been characterized. All the S. wien strains were found to carry three types of plasmids: an IncFI R-Tc Cm Km Ap (resistance to tetracycline, chloramphenicol, kanamycin, and ampicillin) plasmid, either conjugative or nonconjugative, of large size (90 to 100 megadaltons); an R-Ap Su Sm (resistance to ampicillin, sulfonamide, and strep...

Wien Fireball Model of Relativistic Outflows in Active Galactic Nuclei

We study steady and spherically symmetric outflows of pure electron-positron pair plasma as a possible acceleration mechanism of relativistic jets up to a bulk Lorentz factor of greater than 10. We assume that at the inner boundary a “Wien fireball” is realized, which is optically thick to Compton scattering but thin to absorption and in a Wien equilibrium state between pairs and photons at a r...

Electronic structure of solids with WIEN 2 k

Aspects of the progress over the last 40–50 years in calculating the electronic structure of solids and surfaces are sketched in the context of collaboration on the code now called WIEN2k. Different facets that are relevant for material sciences are discussed, ranging from quantum mechanics to the augmented plane wave (APW) method, as well as improvements in computer hardware and algorithms and...

Integrated Circuit Implementation of Wien-bridge Chaos Generator

* This work was supported in part by Dean of the Faculty of Electronics and Information Technology, Warsaw University of Technology, under grant No. 503 “G”/1035/263/9. Abstract The paper presents the fully integrated design of the Wien-bridge chaos generator with the piecewise linear element built of MOS transistors. The circuit is implemented using SC technique. It is shown that this techniqu...
