  1. 11. A Study of Some Temporal Properties of the Human Visual Evoked Potential, and Their Relation to Binocular Function

    Författare :Björn Johansson; Peter Jakobsson; Anders Sjöström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VEP Visual Evoked Potential ; contrast sensitivity; binocularity; latency; Fourier analysis; strabismus; amblyopia; Ophtalmology; Oftalmologi;

    Sammanfattning : As disturbed binocular functions in small children may lead to severe amblyopia it is of interest to detect it as early as possible. Most tests for binocular functions, however, demand active cooperation and may be unreliable in children up to 4-5 years of age. LÄS MER

  3. 12. Strategists and Academics

    Författare :Anders Broström; Hans Lööf; Björn Hårsman; Reinhilde Veugelers; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; public research; spillovers; university-industry; innovation; R D interaction; rationales for interaction; geographic proximity; R D strategy; Economics; Nationalekonomi;

    Sammanfattning : This doctoral thesis consists of five self-contained essays on interaction in R&D between university researchers and private firms. Together, these essays explore the conditions under which private firms benefit from spillovers from publicly funded and organised research. LÄS MER

  4. 13. Laboratory Seismic Testing of Asphalt Concrete

    Författare :Anders Gudmarsson; Nils Rydén; Björn Birgisson; Hervé Di Bendetto; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nondestructive laboratory seismic testing to characterize the complex modulus and Poisson’s ratio of asphalt concrete is presented in this thesis. These material properties are directly related to pavement quality and the dynamic Young’s modulus is used in thickness design of pavements. LÄS MER

  5. 14. Resonance Testing of Asphalt Concrete

    Författare :Anders Gudmarsson; Nils Rydén; Björn Birgisson; Mihai Marasteanu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resonance frequencies; Modal testing; Frequency response functions; Cyclic loading; Tension-compression tests; Complex modulus; Complex Poisson’s ratio;

    Sammanfattning : This thesis present novel non-destructive laboratory test methods to characterize asphalt concrete. The testing is based on frequency response measurements of specimens where resonance frequencies play a key role to derive material properties such as the complex modulus and complex Poisson’s ratio.

  7. 15. Therapy in inflammatory bowel disease

    Författare :Anders Gustavsson; Björn Moum; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin; Medicine;

    Sammanfattning : The aim of this thesis is to study treatment of inflammatory bowel disease with respect to an acute severe attack of ulcerative colitis and endoscopic balloon dilation in stricturing Crohn’s disease.A retrospective follow-up was made in 158 patients who were given intensive intravenous corticosteroid treatment due a severe, moderate, or mild attack of ulcerative colitis between 1975 and 1982.
