  1. 16. Vertical Trade

    Författare :Anna Andersson; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Trade in intermediate inputs; fragmentation; private standards; rules of origin; duration;

    Sammanfattning : This thesis consists of three separate papers. They are all empirical papers that examine how fragmentation of production processes and global value chains have affected international trade patterns. The first paper focuses on how private standards in the increasingly geographically fragmented food sector affect firm-import behaviour. LÄS MER

  3. 17. Effects of confinement and initiation delay on fragmentation and waste rock compaction : Results from small scale tests

    Författare :Daniel Johansson; Gideon Chitombo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : Sub-level caving (SLC) is classified as a mass mining method and there is an increasing interest in its application worldwide and in a very wide range of geotechnical environments. Design of sub-level blasting rounds and optimization has become more important now when the sizes of the blasting rings have become larger. LÄS MER

  4. 18. The spatial structure of genetic and morphometric variation in Corylus avellana (Betulaceae): pattern and scale

    Författare :Helena Persson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .; taxonomy; morphology; Systematic botany; Öland; clonal structure; marginal and central populations; image analysis; aerial photographs; morphometric variation; allozymes; Corylus avellana; genetic variation;

    Sammanfattning : In the present thesis, I investigated the spatial structure of genetic and morphometric variation in the widespread wind-pollinated shrub Corylus avellana (L.) Betulaceae, hazel, and related the variation to geographic distribution and different spatial scales. LÄS MER

  5. 19. Fragmentation and waste rock compaction in small-scale confined blasting

    Författare :Daniel Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Sub-level caving (SLC) is an important mass mining method, used at LKAB e.g. The caved rock or debris at the SLC interface reduces the fragmentation and the swelling of the blasted ring and it dissipates the explosive energy. These phenomena may immobilize the blasted ring, causing ore losses. LÄS MER

  7. 20. The Development of Parliamentarism in Western Europe

    Författare :Simon Davidsson; Statsvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; parlamentarism; partisystem; västeuropa; institutionell förändring; parliamentarism; party systems; Western Europe; institutional change;

    Sammanfattning : This dissertation describes and explains the development of parliamentarism in Western Europe. Defining parliamentarism as an institutional solution in which the government is politically responsible to parliament only, I use country historiography to map out a tug-of-war between parliament and the head of state over the ability to make governments resign or maintain them in office in 11 West European countries since the establishment of national parliaments.
