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

    Author : Georgios Giovanoulis; Cynthia A. de Wit; Jörgen Magnér; Brice Appenzeller; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

    Author : Marianne Flinck; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Soil Nailing. A Laboratory and Field Study of Pullout Capacity

    Author : Gunilla Franzén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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.

  7. 5. Gap Waveguide Technology- Electromagnetic Packaging and Transitions

    Author : Astrid Algaba Brazalez; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rectangular waveguide; packaging; transition; coplanar waveguide; microstrip; millimeter waves; gap waveguide; perfect magnetic conductor;

    Abstract : The scarcity of available frequency bands for new wireless communication systems, as well as the growing need for higher capacity, motivates the current interest in moving upwards in frequency. The millimeter wave frequencyrange is very attractive to allocate potential commercial opportunities such as short range wireless communications that allow high-speed data/video transmission, and automotive radars for both driver assistance and increasedsafety.
