  1. 11. Integration of logistics network in local food supply chains

    Författare :Techane Bosona; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The demand for locally produced food is increasing as global food supply system has considerably affected the confidence of consumers by increasing tonne-kilometres, food safety risk, environmental impact, and disconnecting local food producers and consumers. However, local food suppliers are not in the position to compete with large scale food supply systems due to high logistics costs. LÄS MER

  3. 12. Disentangling clusters : agglomeration and proximity effects

    Författare :Göran Lindqvist; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Clusters are spatial agglomerations of firms in related industries. Although industry clusters have existed for centuries, the cluster concept has only recently been formulated in economic terms and has begun to attract considerable interest from scholars and policymakers over the last 20 years.

  4. 13. Geophysical 3D models of Paleoproterozoic Iron Oxide Apatite mineralization’s and Related Mineral Systems in Norrbotten, Sweden

    Författare :Oskar Rydman; Maxim Smirnov; Thorkild Maack Rasmussen; Tobias Bauer; Niklas Juhojuntti; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Magnetotellurics; 3D Inversion modelling; Classification; Potential fields; Mineral system; Petrophysics; mineral exploration; common earth modeling; iron oxide-apatite; Northern Norrbotten ore province; Tillämpad geofysik; Applied Geophysics;

    Sammanfattning : The Northern Norrbotten ore district hosts a multitude of Sweden’s mineral deposits including world class deposits such as the Malmberget and Kirunavaara Iron oxide apatite deposits, the Aitik Iron oxide copper gold deposit, and a multitude of smaller deposits. Northern Norrbotten has been shaped by tectonothermal events related to the evolution of the Fennoscandian Shield and is a geologically complex environment. LÄS MER

  5. 14. School choice, space and the geography of marketization- Analyses of educational restructuring in upper secondary education in Sweden

    Författare :Anna Maria Fjellman; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; school choice; school market; marketization; space; equity; quasi-market; differentiation; spatial justice;

    Sammanfattning : The main aim of the dissertation is to investigate, analyze and create a research-based understanding of the spatialities of the Swedish school choice in upper secondary education using a socio-spatial framework. The dissertation is comprised of three empirical studies based on six cohorts of register data from The Gothenburg Longitudinal Database. LÄS MER

  7. 15. Development, validation and application of advanced neuroimaging analysis tools for in vivo neuroreceptor studies

    Författare :Zsolt Cselényi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :PET; neuroreceptor; multi-receptor analysis; kinetic analysis; parametric imaging; wavelet filtering; artificial neural network; unsupervised cluster analysis;

    Sammanfattning : Positron emission tomography (PET) is an imaging technology, which can be used to study neuroreceptors in the human brain in vivo. The technique estimates the regional binding of radiolabelled ligands to neuroreceptors and the data are commonly displayed as images showing the distribution of radioactivity in the brain volume.
