THE STRUCTURE OF THE LOCAL INTERSTELLAR MEDIUM. I. HIGH-RESOLUTION OBSERVATIONS OF Fe ii, Mg ii, AND Ca ii TOWARD STARS WITHIN 100 PARSECS
High-resolution absorption measurements ( =D & 100;000) of the resonance lines of Fe ii, Mg ii, and Ca ii are presented for all available observed targets within 100 pc. The Fe ii andMg ii spectra were obtained with the Goddard High Resolution Spectrograph (GHRS) and the Space Telescope Imaging Spectrograph (STIS) instruments aboard the Hubble Space Telescope (HST). Of the 63 observations of ta...
متن کاملNifedipineExtended-release Tablets, USP30 mg, 60 mg and 90 mg
Nifedipine Extended-release Tablet depends for its action on the existence of an osmotic gradient between the contents of the tablet core and fluid in the GI tract. Drug delivery is essentially constant as long as the osmotic gradient remains constant, and then gradually falls to zero. Upon swallowing, the biologically inert components of the tablet remain intact during GI transit and are elimi...
متن کاملIsotope Shift in Mg I
The lines of the Mg I spectrum, lying in the visible and in the photographic infrared regions, have been examined and some of them found to show structure. It is pointed out that the structure should be attributed to isotope shift, which, in the case of the 3s3p 'P —3s3d 'D series, owes its origin to the fact-that the smd 'D terms, perturbed by the p''D term, have passed on to this term some of...
متن کاملMg II Absorbing Galaxies : Morphologies and Kinematics
In this contribution, we review our current knowledge of the properties of galaxies, and their extended halos, selected by Mg ii absorption in the spectra of background quasars. We then describe recent efforts to quantify the morphologies and orientations of galaxies and explore how these relate to the gas kinematics. In a sample of 26 galaxies, we find no clear connection between the orientati...
متن کاملFRACTIONAL RECRYSTALLIZATION KINETICS IN DIRECTLY COLD ROLLED Al-Mg, Al-Mg-Sc AND Al-Mg-Sc-Zr ALLOY
The evaluation of texture as a function of recrystallization has been characterized for directly cold rolled Al-6Mg, Al-6Mg-0.4Sc and Al-6Mg-0.4Sc-0.2Zr alloys. Samples were annealed isothermally at 400 °C for 1 to 240 minutes to allow recrystallization. Recrystallization kinetics of the alloys is analyzed from the micro-hardness variation. Isothermally annealed samples of aluminum alloys were ...
