  1. 1. Hydraulic- hydromorphologic analysis as an aid for improving peak flow predictions

    Författare :Anna Åkesson; Anders Wörman; Göran Lindström; Rolf Larsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrological modelling; peak flow predictions; distributed routing; parameterisation; stage-dependency; Hydrology; Hydrologi;

    Sammanfattning : Conventional hydrological compartmental models have been shown to exhibit a high degree of uncertainty for predictions of peak flows, such as the design floods for design of hydropower infrastructure. One reason for these uncertainties is that conventional models are parameterised using statistical methods based on how catchments have responded in the past. LÄS MER

  3. 2. Peakflow response of stream networks : implications of physical descriptions of streams and temporal change

    Författare :Anna Åkesson; Anders Wörman; Alberto Viglione; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Streamflow routing; peakflow predictions; parameterization; hydrological response; stage-dependency; flooded cross-sections; stream networks; backwater effects; temporal change; land use change; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Through distributed stream network routing, it has quantitatively been shown that the relationship between flow travel time and discharge varies strongly nonlinearly with stream stage and with catchment-specific properties.Physically derived distributions of water travel times through a stream network were successfully used to parameterise the streamflow response function of a compartmental hydrological model.

  4. 3. Ögonblickets pedagogik : Yrkesgrupper i samtal om specialpedagogisk kompetens vid barn-och ungdomshabiliteringen

    Författare :Kerstin Åman; Ulf Janson; Eva Björck - Åkesson; Anders Möller; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Special needs education; educational competence; child and youth habilitation; sphere of activities; field of knowledge; professional language; speech genres; focus groups; metaphors; early childhood intervention; conceptualised speech; phronesis; Education; Pedagogik;

    Sammanfattning : This thesis is about special needs educational competence of educators working in collaborating teams within child and youth habilitation centres. The pedagogy of the moment stands for the decisions made by educators, based on their observations made when meeting the child in its different environments. LÄS MER

  5. 4. Transcriptional profiling of human embryonic stem cells and their functional derivatives

    Författare :Jane Synnergren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transcription; differentiation; human embryonic stem cells; gene expression; Naturvetenskap;

    Sammanfattning : Human embryonic stem cells (hESCs) represent populations of pluripotent, undifferentiated cells with unlimited replication capacity, and with the ability to differentiate into any functional cell type in the human body. Based on these properties, hESCs and their derivatives provide unique model systems for basic research on embryonic development. LÄS MER
