  1. 1. Quality of snow deposited in urban areas : Storage, load assessment and release of selected pollutants with snowmelt

    Author : Arya Vijayan; Maria Viklander; Helene Österlund; Jiri Marsalek; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Abstract : Snow deposited in urban areas is exposed to pollutants originating from traffic, wet and dry atmospheric deposition, de-icing chemicals and traction materials. The conventional pollutants found in urban snow include solids (TSS), metals (Zn, Cu, Cd, Pb, etc.), Polycyclic Aromatic Hydrocarbons (PAHs), and chlorides. READ MORE

  2. 2. Studies of molecular clouds at the Galactic centre

    Author : Roland Karlsson; Kambiz Fathi; Aage Sandqvist; Andreas Eckart; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Galactic centre; Astronomy; astronomi;

    Abstract : Interstellar molecular clouds play an essential role in the Universe. Such clouds are invoked for the production and destruction of stars, galaxies and gas and also for energy transport in galaxies. READ MORE

  3. 3. Theoretical Studies of Binaries in Astrophysics

    Author : Johann Dischler; Astronomi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Astronomi; Astronomy; Galaxy: centre; Stars: mass-loss; Binaries: close; Binaries: eclipsing;

    Abstract : This thesis introduces and summarizes four papers dealing with computer simulations of astrophysical processes involving binaries. The first part gives the rational and theoretical background to these papers. In paper I and II a statistical approach to studying eclipsing binaries is described. READ MORE

    Abstract : IntroductionThanks to achievements in paediatric heart surgery and medicine, the population of adults with surgically repaired or palliated congenital heart defects is growing. Many of these adults have reduced exercise capacity, weaker muscular strength and shorter height, all of which suggest an altered body composition. READ MORE

  5. 5. Interactions of chiral ions and molecules in gas phase : Towards an understanding of chiral recognition mechanism

    Author : Oleksii Rebrov; Mats Larsson; Richard Thomas; Vitali Zhaunerchyk; Anne Zehnacker-Rentien; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : This thesis comprises the research related to interactions of enantiopure amino acids with chiral and achiral molecules in gas phase. The investigation of the mechanism responsible for chiral discrimination is of the special interest in this work. READ MORE
