  1. 21. Kinetics for oxidation of CRUD model compounds

    Författare :Maryam Abili Nejad; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reactor chemistry; radiolysis; oxidation; kinetics; crud; metal oxide;

    Sammanfattning : The formation of CRUD (Chalk River Unidentified Deposit) inwater-cooled nuclear reactors constitute a severe problem. Thestability of CRUD under reactor conditions (high flux ofionizing radition, high temperature and pressure) must be knownin order to minimize the problem. LÄS MER

  4. 23. Data preparation, hydrodynamic and contaminant transport shallow-water simulations of Lake Victoria

    Författare :Seema Paul; Vladimir Cvetkovic; Jesper Oppelstrup; Roger Thunvik; Felix Mtalo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake bathymetry model; Steady-state analysis; Numerical model validation; Lake water balance; Correlation and seasonal variations; Solute transport; Vattendjupskarta; Validering av numerisk modell; Vattenbalans; Korrelationer och säsongs-variation; Transport av lösliga ämnen; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : This study explores shallow lake numerical hydrodynamic processes that support model development and validation, extreme events and effects of water circulation in Lake Victoria. Lake Victoria is the second largest freshwater lake in the world, and the largest in East Africa. LÄS MER

  5. 24. Comparison of the geochemistry of the regulated Lule River and the unregulated Kalix River, Northern Sweden

    Författare :Magali Collomp; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : Hydropower production in Sweden represents nearly 50% of the total electricity production in Sweden. The aim of this study is to evaluate the impact of stream regulation on the geochemistry of the Lule River, northern Sweden, which is the largest and the most important river for waterpower production in Sweden.

  7. 25. Three Dimensional Hydro-Morphological Modeling of Tigris River

    Författare :Ammar Ali; Robert William Duck; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The River Tigris is a major river in Iraq. It divides Baghdad, the capital of Iraq, in two parts. The reach of the river within Baghdad is about 60 km long. The climate change within the region and the construction of hydraulic structures upstream of Baghdad has reduced the water discharge of the river by 44%. LÄS MER
