  1. 1. Restraint factors and partial coefficients for crack risk analyses of early age concrete structures

    Författare :Martin Nilsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : It is well known for contractors that due to volume change during the hydration phase in concrete structures, large stresses can arise if the structures are restrained, stresses that may cause extensive cracking. Crack risk estimation of early age concrete structures can be based on five steps. LÄS MER

  4. 3. High-Resolution Measurement of the 4He(g,n) Reaction in the Giant Resonance Region

    Författare :Björn Nilsson; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tagged photons; photonuclear reactions; liquid helium; neutron detectors; liquid scintillators; giant resonances; angular distributions; differential cross sections; total cross sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:2003:Nilsson;

    Sammanfattning : A comprehensive near-threshold 4He(g,n) absolute cross section measurement has been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 20 < Eg < 45 MeV tagged photons (covering the Giant Dipole Resonance energy region) were directed towards a liquid 4He target, and knocked-out neutrons were detected in a pair of 60 cm x 60 cm vetoed NE213A liquid scintillator arrays.

  5. 4. Från sockenkommun till storkommun : En analys av storkommunreformens genomförande 1939-1952 i en nationell och lokal kontext

    Författare :Erik Wångmar; Peter Aronsson; Lennart Johansson; Torbjörn Nilsson; Växjö universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; municipal amalgamation; Swedish decision-making model; local self government; History; Historia; Historia; History;

    Sammanfattning : The primary aim of this study is to provide a deeper and more complete understanding of why the great municipal amalgamation (storkommunreformen) during the 1940s became the political solution to the problem that the Government believed many of Sweden’s municipalities had in satisfactorily providing for a local welfare society. The study also describes the results of this large-scale reorganization process. LÄS MER

  7. 5. Planning in a sustainable direction - the art of CONSCIOUS CHOICES

    Författare :Kristina L. Nilsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Planners; planning; sustainable development; discources.; Architecture;

    Sammanfattning : A main challenge facing spatial planning today issustainable development, in official documents defined asecological, social and economic sustainability. In a powerperspective these three dimensions can be characterised ascompeting discourses. LÄS MER
