  1. 1. Hydrogeochemistry of arsenic, fluoride, and other trace elements in groundwater in northern Tanzania : Occurrence, distribution, and impacts on drinking water quality

    Author : Fanuel Josephat Ligate; Prosun Bhattacharya; Felix W Mtalo; Jyoti Prakash Maity; Joyanto Routh; KTH; []
    Keywords : Arsenic; Fluoride; Groundwater; Lake Victoria basin; Risk assessment; Sanya alluvial plain; Tanzania.; Aseniki; Bonde la Ziwa Victoria; Floridi; Maji yaliyopo ardhini; Tanzania; Tathmini ya hatari; Uwanda wa Aluvia ya Sanya.; Arsenik; Fluorid; Grundvatten; Viktoriasjön; Riskbedömning; Sanya alluvial slätt; Tanzania.; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : The occurrence of arsenic (As), fluoride (F-), and other trace elements (TEs) with potential toxicity in groundwater is a global environmental concern. According to the National water resource mapping database, about 76 % of the drinking water supply in Tanzania is abstracted from groundwater sources. READ MORE

  2. 2. Backward and Forward Nonlinear Optical Processes in Potassium Titanyl Phosphate

    Author : Kjell Martin Mølster; Fredrik Laurell; Valdas Pasiskevicius; Ulf L. Österberg; Stefano Taccheo; KTH; []

    Abstract : Second-order nonlinear optical processes generate radiation across a broad spectrum, including UV and the far-infrared. In this thesis, new light sources in the near(NIR) and mid infrared (MIR) using three-wave mixing geometries in periodically poled potassium titanyl phosphate (PPKTP) is studied. READ MORE

  3. 3. Identifying risk of type 2 diabetes : epidemiologic perspectives from biomarkers to lifestyle

    Author : Margareta Norberg; Lars Weinehall; Jan W Eriksson; Christer Andersson; Mai-Lis Hellénius; Umeå universitet; []

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geokemi; Applied Geochemistry;

    Abstract : Little attention has been paid to tailings from skarn ore deposits and their environmental impact, even though they can contain elevated content of elements of potential concern. Historical skarn tailings from a former scheelite mine at Yxsjöberg, Sweden, containing e.g. READ MORE

  5. 5. Production and characterization of intraspecific somatic hybrids of potato (Solanum tuberosum L.)

    Author : Sylvia Waara; Uppsala universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : A culture protocol has been developed for mesophyll protoplasts isolated from various d¡haploid clones of potato. A large number of call¡ was obtained after serial dilution of the cultures w¡th a suitable amount and type of medium at different stages of cell colony development. READ MORE
