  1. 1. Från kvalitetsidé till kvalitetsregim : Om statlig styrning av skolan

    Författare :Hans Nytell; Ulf P. Lundgren; Eva Forsberg; Peder Haug; Uppsala universitet; []
    Nyckelord :Education; educational systems; state governing; quality assurance; quality regime; power; legitimacy.; Pedagogik; Pedagogik; Education;

    Sammanfattning : The Swedish educational contexts were in the 1990ies characterized by extensive and rapid changes towards decentralisation and governing through goals and results. A significant feature was the introduction of instruments and techniques with a common core of “quality”. LÄS MER

  3. 2. Metapopulation ecology of Osmoderma eremita - dispersal, habitat quality and habitat history

    Författare :Jonas Hedin; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; extinction debt; habitat history; habitat quality; pheromone; telemetry; capture-mark-recapture; metapopulation; dispersal; oak; Osmoderma eremita; beetle; Animal ecology; Djurekologi;

    Sammanfattning : This thesis starts with a review of different biodiversity assessment methods in forests and the rest deals with the metapopulation ecology of Osmoderma eremita, a threatened beetle living in hollow trees. I concentrate on the effect of dispersal, habitat quality and habitat history for the presence, population size and future survival of this species. LÄS MER

  4. 3. Biofiltration technologies for stormwater quality treatment

    Författare :Godecke-Tobias Blecken; Jean-Luc Bertrand-Krajewski; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Due to high runoff volumes and peak flows, and significant contamination with (inter alia) sediment, metals, nutrients, polycyclic aromatic hydrocarbons and salt, urban stormwater is a major cause of degradation of urban water ways. Since current urban drainage systems, which heavily rely on piped sewer networks, may not be sustainable, attempts are being made to develop and refine sustainable urban drainage solutions, notably in Water Sensitive Urban Design (WSUD) and Low Impact Development (LID) concepts.

  5. 4. Re-establishment of connectivity for fish populations in regulated rivers

    Författare :Olle Calles; Larry Greenberg; Lars Nyberg; David Scruton; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Attraction efficiency; Connectivity; Flow regime; Hyporheic water quality; Nature-like fishway; Passage efficiency; Regulated river; Remedial measures; Salmo trutta; Biology; Biologi; Biology; Biologi;

    Sammanfattning : The hydropower industry has altered connectivity in many rivers during the last century. Many fish species depend on both an intact longitudinal connectivity to be able to migrate between spawning, feeding and winter habitats, and vertical connectivity for development and survival of incubating embryos and larvae in the gravel.

  7. 5. Generation of Leachate and the Flow Regime in Landfills

    Författare :David Bendz; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; model; transport; flow; leachate; water; hydrology; landfill; MSW; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : The environmental impacts of landfills are associated mainly with the emission of leachate and biogas. Sanitary landfilling aims to stabilize the landfill in a efficient and controlled way, so that the environmental impacts are minimized. When a sanitary landfill has attained its final storage quality, it can be integrated into the environment. LÄS MER
