  1. 1. Participating in Energy Systems through Everyday Designs – Exploring roles for households in a more sustainable energy future

    Författare :Sara Renström; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smart energy; sustainable energy systems; sustainable design; user-centred design; demand-side management; smart home; energy use;

    Sammanfattning : As households we participate in energy systems when, in the course of our everyday energy-reliant activities, we create a demand for energy and when we engage in energy-managing activities such as choosing an energy provider and deciding to support a specific source of energy. In this way, everyday life has an impact on the energy sector, and vice versa. LÄS MER

  3. 2. Dietary energy density and energy intake in cancer patients

    Författare :Ola Wallengren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; cachexia; diagnostic criteria; quality of life; nutritional support; energy intake; energy balance; dietary energy density;

    Sammanfattning : Background & Aims: Cachexia is frequent in advanced cancer and is associated with adverse outcomes; however, definite diagnostic criteria for cachexia are not established. Diet energy density (ED) may affect energy intake (EI) and energy balance. Patient characteristics may also influence such associations. LÄS MER

  4. 3. Using Energy Fluxes to Analyze the Hydrodynamic Performance of Marine Propulsion Systems

    Författare :Jennie Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Propulsor-Hull interaction; Control volume analysis; RANS; Energy balance analysis; CFD;

    Sammanfattning : The strive towards more fuel efficient ships is a continuously ongoing process, motivated by both economic and regulatory reasons. An important aspects to consider for the final fuel consumption is the propulsion system performance in relevant operating conditions. LÄS MER

  5. 4. Thermal comfort and energy in residential buildings in a cold climate

    Författare :Petter Lundqvist; Mikael Risberg; Erik Elfgren; Patrik Rohdin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Building design typically has a focus on energy use and economy. The indoor environment is often overlooked or simplified to such an extent that essential aspects are neglected. Additionally, introducing technologies for improving energy efficiency can also affect the indoor thermal climate and, in turn, the perceived indoor comfort. LÄS MER

  7. 5. Simplifying complex models : Application of modeling tools in exposure assessment of organic pollutants

    Författare :Emma Undeman; Michael McLachlan; Kathrin Fenner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mass balance model; environmental modeling; exposure modeling; bioaccumulation; organic contaminants; emission estimate; plant model; steady state; poly parameter linear free energy relationship; PPLFER; ecosystem susceptibility; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Thousands of chemicals are used in society, but the exposure to humans and other organisms has been measured only for a small number of compounds. Modeling tools constitute low-cost and effective alternatives to measurements for the assessment of exposure. LÄS MER
