  1. 16. Fluid and suspension hydrodynamics in the impeller discharge flow of stirred tanks

    Författare :Ziyun Yu; KTH; []
    Nyckelord :hydrodynamics; stirred tank; phase Doppler anemometer;

    Sammanfattning : The hydrodynamics of an agitated tank have been studied byphase-Doppler anemometry. The focus is on the impeller anddischarge region of a 45o pitched blade turbine (PBT). Thestudy includes agitation of pure water as well as of a dilutesuspension of process particles. LÄS MER

  3. 17. Area Selective Chemical Vapor Deposition of Metallic Films using Plasma Electrons as Reducing Agents

    Författare :Hama Nadhom; Henrik Pedersen; Daniel Lundin; Kostas Sarakinos; Erwin Kessels; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Metallic films are used to improve optical, chemical, mechanical, magnetic, and electrical properties and are therefore of high importance in many applications, from electronics and catalysis, environmental protection and health, to wearable and flexible electronic materials. Many of these applications, however, require that the metal films are deposited uniformly on topographically complex surfaces and structures. LÄS MER

  4. 18. Development of the Laitaure Delta, Swedish Lappland : A Study of Growth, Distributary Forms and Processes

    Författare :Hans Andrén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Recent delta formation; hydraulic geometry; distributary forms and processes; X-ray radiography; Sarek; Lappland; Earth Science with specialization in Physical Geography; Geovetenskap med inriktning mot naturgeografi;

    Sammanfattning : Deltaic processes were studied on the Laitaure delta. Specific aims were to: analyse forms and processes in distributaries with regard to hydraulic geometry relationships; investigate the distribution of water into different distributaries; analyse the morphological development of the delta; and quantify the advance of the delta front.

  5. 19. Soil and stream water chemistry in a boreal catchment - interactions, influences of dissolved organic matter and effects of wood ash application

    Författare :Sara H Norström; Ulla Lundström; Dan Bylund; Mittuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Boreal forest; catchment studies; dissolved organic carbon; soil solution; Chemistry; Kemi;

    Sammanfattning : Two small bordering catchments in Bispgården, Central Sweden, wereinvestigated in regard to soil solution and stream water chemistry during the frostfree seasons of 2003-2007. Both catchments were drained by first order streams,Fanbergsbäcken and Gråbergsbäcken, and in Fanbergsbäckens catchment anextensive investigation of the soil and soil solution chemistry was conducted bylysimeter and centrifugation sampling.

  7. 20. Hydrological processes in firn on Storglaciären, Sweden

    Författare :Thomas Schneider; Andrew G. Fountain; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geography; Physical Geography; geografi med naturgeografisk inriktning;

    Sammanfattning : Understanding hydrological processes in temperate glaciers is important for both scientific and practical issues. Modelling glacier response to climatic change and the use of water from glaciers for electric power generation are some topics that require detailed information on water storage and drainage in glaciers.
