In this paper we review the modeling of the Local Bubble (LB) with special emphasis on the progress we have made since the last major conference “The Local Bubble and Beyond (I)” held in Garching in 1997. Since then new insight was gained into the possible origin of the LB, with a moving group crossing its volume during the last 10 15 Myr being most likely responsible for creating a local cavit...

I present an overview of some of the recent advances in our understanding of the distribution and evolution of the ordinary, baryonic matter in the universe. Two observations that strongly suggest that most of the baryons seen at high redshift (z ≥ 2) have turned into some forms yet undetected at z = 0 are highlighted. With the aid of large-scale cosmological hydrodynamic simulations, it is sho...

The endogenous tonB gene of Escherichia coli was used as a target for 9-aminoacridine-induced mutations that were identified in recA(-) and uvrA(-) cells. The cytotoxicity of 9-aminoacridine was enhanced in the uvrA and recA strains compared to the wild-type strain, and the mutagenicity of 9-aminoacridine in the uvrA and recA strains was similar to that in the wild type. For all three strains, ...

Approximately 30− 40% of all baryons in the present day universe reside in a warm-hot intergalactic medium (WHIM), with temperatures between 10 < T < 10 K. This is a generic prediction from six hydrodynamic simulations of currently favored structure formation models having a wide variety of numerical methods, input physics, volumes, and spatial resolutions. Most of these warm-hot baryons reside...

NGC 4449 is an irregular galaxy with a moderately high star formation activity. The massive stars in NGC 4449 have given rise to many bright HII regions, superbubbles, supergiant shells, and “chimney-like” radial filaments. ROSAT X-ray observations of NGC 4449 have revealed four point-like sources and a wide-spread diffuse emission. The spectral properties of the diffuse component suggest that ...

Recent developments for the finite-element modelling of the plastic forming of the metallic materials are described in the paper. The model consists of three parts; mechanical, thermal and microstructural components. First two are described in earlier publication and the focus here is put on the modelling of the microstructural phenomena. Two approaches are described. First uses conventional cl...
