  1. 1. What contributes to human body burdens of phthalate esters? : An experimental approach

    Författare :Georgios Giovanoulis; Cynthia A. de Wit; Jörgen Magnér; Brice Appenzeller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phthalates; Alternative plasticizers; DINCH; In vivo screening; Urine; Nails; Air; Dust; Hand wipes; Duplicate diet; Predictors of exposure; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Phthalate esters (PEs) and alternative plasticizers used as additives in numerous consumer products are continuously released into the environment leading to subsequent human exposure. The ubiquitous presence and potential adverse health effects (e.g. LÄS MER

  3. 2. Connections for Timber-Framed Structures - Assembly Properties and Structural Behaviour

    Författare :Dan Engström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frames; nails; connections; structures; interaction; glue; assembly; timber; economy; semi-rigidity; adhesive; joints; splices;

    Sammanfattning : By tradition, the design and development of connections has focused on the optimization of strength and stiffness. The subject of this thesis is the interaction between the assembly and structural properties of connections for timber-framed structures. LÄS MER

  4. 3. Úhelníky s prolisem ve spojích dřevěných prvků

    Författare :Petr Sejkot; Petr Kuklík; Miloš Drdácký; Antonín Lokaj; Czech Republic Czech Technical University in Prague; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; angle brackets with a rib; annular ring nails; metal works for timber structures; static load tests of joints; numerical simulations of tests of joints; analytical static models of joints.; úhelníky s prolisem; kroužkové konvexní hřebíky; kování pro přípoje dřevostaveb; statické zatěžovací zkoušky přípojů; numerické simulace zkoušek přípojů; analytické statické modely přípojů.;

    Sammanfattning : The thesis deals with appropriate methods to determinate load-bearing capacities of timber structures joints using angle brackets with a rib. In these joints, annular ring nails were used as connectors.During an experimental approach, full-scale load tests of whole joints were performed. LÄS MER

  5. 4. Femoral shaft fractures in children and adolescents; stability, residual deformity and recovery of physical function

    Författare :Marianne Flinck; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Femoral fractures; Child; Treatment outcome; Leg length discrepancy; Elastic intramedullary nails; Biomechanics; Fracture fixation; Three-dimensional gait analysis; Function recovery;

    Sammanfattning : Femoral shaft fracture is the most common injury requiring hospital admission among children. The limited number of studies makes it challenging to provide accurate prognosis for recovery after femoral shaft fractures in children and adolescents. LÄS MER

  7. 5. Soil Nailing. A Laboratory and Field Study of Pullout Capacity

    Författare :Gunilla Franzén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Soil Nailing is a technique for reinforcing soil in situ, increasingly utilised as an economical alternative to conventional earth reinforcing techniques. However, today the design is based on an assumed value of the pullout capacity of nails, which later is verified by pullout tests during the construction, which in turn limits the possibility of optimising the design.
