Chemical Composition Study of an Accretion Episode in the Herbig Candidate Star PDS080observed in the Balmer lines Hα, Hβ, Hγ, Hδ and other metallic lines such as Na i D and Ca ii. In a preliminary chemical study of the infalling structure we analysed these line profiles to determine whether the redshifted components are due to a gaseous structure or the evaporation of a solid body.

The Oph-Sco-Lup-Cen-Cru-Mus-Cha Star-formation RegionA brief review is presented of some of the conflicting models that have been proposed in the literature, like the Gould Belt model and sequential star formation. We argue that the presence of a spiral arm can explain most of the observations of that super-association.

Sacy — A Search for Associations Containing Young StarsOSAT sources were observed, covering a large area in the Southern Hemisphere. The newly identified young stars present a patchy distribution in UVW and XYZ, revealing the existence of huge nearby young associations. Here we present the associations identified in this survey.

Age Determination of the Ursa Major Associationing et al.(2003) based on post-main-sequence models for the A-stars similar to Soderblom & Mayor (1993). In the further we will discuss the age of the Ursa Major association derived from pre-main-sequence models of different authors for the low-mass companion to χ. Orionis A.

Solar-Type Post-T Tauri Stars in the Nearest OB Subgroupss of the post-T Tauri stars in the LCC and UCL subgroups (<1.6 km s. and <2.2 km s., respectively; 95% CL) using Monte Carlo simulations of Tycho-2 proper motions for candidate subgroup members. I also demonstrate that a new OB subgroup recently proposed to exist in Chamaeleon probably does not.

Mathieu degree of progression..The stage of hemodynamic cerebral ischemia has been defined by an increase of OEF, but could be reconsidered from different patterns of the engagement of compensatory reserve capacities, and misery perfusion could be classified into three subtypes, such as acute, chronic, and long-standing misery perfusion.

S. L. A. Vieira,W. J. B. Corradi,S. H.P. Alencar,L. T. S. Mendez,C. A. Torres,G. Quast,M. M. Guimarãl, and sIA rupture; these studies show the potential of CFD as a diagnostic tool. This review discusses the limitations of CFD and of the studies performed, and what needs to be done in order to develop CFD into a useful diagnostic tool to determine aneurysm-specific rupture risk.
