  1. 21. District heating in future Europe : Modelling expansion potentials and mapping heat synergy regions

    Författare :Urban Persson; Sven Werner; Lars J. Nilsson; Sweden Gothenburg Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; district heating; energy efficiency; distribution capital cost; heat demand density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation rate; effective width;

    Sammanfattning : This thesis presents a set of methodologies and approaches to investigate and determine the extent by which district heating can contribute to improved energy system efficiency and reduced carbon dioxide emissions in future Europe. The main motivation for suggesting large-scale implementation of district heating as a structural energy efficiency measure to obtain these objectives originates essentially in the predicament that a majority of European buildings today remain highly dependent on fossil fuels to provide energy needed for space heating and hot water preparation.

  3. 22. Chlorinated organic pollutants in soil and groundwater at chlorophenol-contaminated sawmill sites

    Författare :Ylva Persson; Mats Tysklind; Lars Öberg; Staffan Lundstedt; Jaana Koistinen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; contaminated soil; hydrophobic organic contaminant; chlorinated phenoxyphenol; chlorinated diphenyl ether; chlorinated dibenzofuran; chlorinated dibenzo-p-dioxin; preservation; mobility; colloid; dissolved organic matter; particulate organic matter; groundwater; equilibrium column test; chlorophenol; Environmental chemistry; Miljökemi;

    Sammanfattning : Mixtures of chlorinated organic pollutants can be found in the soils at chlorophenol-contaminated sawmill, including (inter alia) polychlorinated phenols (CPs), phenoxyphenols (PCPPs), diphenyl ethers (PCDEs), dibenzofurans (PCDFs) and dioxins (PCDDs). These hydrophobic compounds have low water solubility and hence low mobility as truly dissolved compounds. LÄS MER

  4. 23. Targeting cytotoxic species in amyloid diseases

    Författare :Malin Lindhagen Persson; Anders Olofsson; Lars Tjernberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; Amyloid-beta; transthyretin; FAP; amyloid; cytotoxic species; oligomers; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Amyloid diseases are a world-wide problem causing great human suffer and large economical costs. Although amyloid deposits, a common denominator in all amyloid disorders, are detrimental to the surrounding tissue, there is a poor correlation between total amyloid burden and clinical symptoms.

  7. 25. Krislärande – konfliktfylld anpassning : Pedagogik för samverkan inför samhällskriser

    Författare :Ing-Marie Persson; Christina Gustafsson; Lars Holmstrand; Arvid Löfberg; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; crisis learning; dialogical learning; emergency preparedness; coordination; knowledge building; knowledge meeting; societal crisis; krislärande; dialogiskt lärande; krisberedskap; samverkan; kunskapsbildning; kunskapsmöten; samhällskris; Education; Pedagogik; Pedagogik; Education;

    Sammanfattning : A societal crisis is an emergency that affects many people and large parts of society, threatening life, health, safety and basic values. In a societal crisis, there is a need for coordination between various bodies in the society. Coordination in societal crises has previously been studied mainly from a management perspective. LÄS MER
