  1. 1. Shaping sustainable food systems Local participation in addressing global challenges

    Detta är en avhandling från Stockholm : Stockholm Resilience Centre, Stockholm University

    Författare :Aniek Hebinck; Stockholms universitet.; [2018]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; food systems; sustainability; food governance; transformative change; participatory processes; participation; civil society; niche level; food policy; urban food; urban agriculture; food poverty; imagined futures; foresight; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : The current unsustainable trajectory of food systems puts the social and ecological processes and functions on which human flourishing depends at risk. This last decade has seen, on one hand, continued insistence on transformative action and on the other, uncertainty and instability with respect to traditional, established institutions, such as the state.

  2. 2. Cascading extinctions in food webs : local and regional processes

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Anna Eklöf; Linköpings universitet.; Linköpings universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cascading extinctions; complexity; connectance; dispersal; food web; local dynamics; regional dynamics; resistance; spatial structure; species loss;

    Sammanfattning : Ecological communities all over the world are loosing biodiversity due to different kinds of human activities and there is an urgent need of understanding how those losses affect the function of the ecosystems on which we all depend. The community's response to species losses is likely to depend on both the structure of the local community as well as its interactions with surrounding communities. LÄS MER

  3. 3. Jet Impingement and Infrared Heating of Cylindrical Foods. Flow and Heat Transfer Studies

    Detta är en avhandling från Department of Food Technology, Lund University

    Författare :Eva Olsson; Lunds universitet.; Lund University.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; fluiddynamik; plasma; Thermal engineering; applied thermodynamics; Gaser; fluid dynamics; plasmas; Gases; RSM; CFD; inverse heat transfer; jet impingement heat transfer; infrared heating; termodynamik; Food and drink technology; Livsmedelsteknik; PIV; SST; food; cylinder;

    Sammanfattning : Popular Abstract in Swedish Jet impingement och infraröd strålning är metoder för snabb värmeöverföring som kan användas för att snabba upp värmeprocesser i livsmedelsindustrin. Värmningshastigheten påverkar viktiga egenskaper hos livsmedlet, t.ex. brunfärgning. LÄS MER

  4. 4. Loss Minimisation in Dynamic Food Processes

    Detta är en avhandling från Department of Food Technology, Engineering and Nutrition, Lund University

    Författare :Marcus Henningsson; Lunds universitet.; Lund University.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Teknik; Technological sciences; CFD; dual plane ERT; ERT; waste minimisation; loss; milk; density; sensor fusion; multivariate calibration; electrical resistance tomography; dairy process; turbidity; conductivity;

    Sammanfattning : The overall aim of the present work was to reduce losses during product changes or during rinsing in continuous food processing, with particular attention to dairy plants. The concept of sensor fusion of common process instruments was implemented as a tool to monitor the milk and fat concentrations in a dairy processing line. LÄS MER

  5. 5. Food in the Future energy and transport in the food system

    Detta är en avhandling från Stockholm : KTH

    Författare :Christine Wallgren; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering Food technology; TEKNIKVETENSKAP Kemiteknik Livsmedelsteknik;

    Sammanfattning : This thesis explores possible future forms of a sustainable food supply system from an energy aspect. Particular attention is devoted to local food supply as a means to reduce energy use for transport. The thesis consists of a covering essay and three studies: one futures study of the entire food supply system and two case studies of local farming. LÄS MER
