  1. 16. Postural and Muscular Responses of Car Occupants under Pre-Crash Conditions

    Author : Ghazaleh Ghaffari; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; vehicle occupant kinematics; pre-crash; evasive maneuvers; lane change; human body model; pre‐pretensioner belt; principal component analysis; linear mixed model;

    Abstract : Advanced integrated safety technologies in modern cars such as collision avoidance intervention and pre-crash activated restraint systems require comprehensive research on how vehicle occupants respond to these systems. The aim of this thesis is to provide insights into car passengers’ body kinematics and muscle activations in representative pre-crash circumstances with respect to two belt configurations (i.

  2. 17. GH Secretion in children. Methodological aspects of determining immunoreactive and bioactive isoforms

    Author : Chatarina Löfqvist; Göteborgs universitet; []
    Keywords : Growth hormone; immunoassay; cross-reactivity; standard; antibody; insulin-like growth factor 1; reference values;

    Abstract : A child's hormone-dependent growth is dependent on multiple factors, although linear growth is closely associated with levels of growth hormone (GH) secretion. As GH in serum exists in several isoforms, some of which may not be identified by immunoassay, possible alterations in the secretion of these different isoforms in childhood may influence growth and/or metabolism.

  3. 18. Effect of estrogen on longitudinal bone growth

    Author : Andrei S Chagin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Growth plate; chondrocytes; estrogen receptors; androgen; tamoxifen.;

    Abstract : Longitudinal bone growth occurs at the growth plate, a thin layer of cartilage between the epiphysis and the metaphysis of long bones. In the growth plate resting chondrocytes proliferate, differentiate into a hypertrophic form, and finally become terminal hypertrophic chondrocytes before giving rise to bone. READ MORE

  4. 19. Placental Function : An Epidemiological and Magnetic Resonance Study

    Author : Sara Sohlberg; Anna-Karin Wikstrom; Matts Olovsson; Ajlana Mulic-Lutvica; Johan Wikström; Karel Marsal; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; body height; body mass index; early preeclampsia; late preeclampsia; magnetic resonance imaging; placenta; perfusion; IVIM; risk factors; energy metabolism; magnetic resonance spectroscopy; 31P-MRS; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : Placental function is central for normal pregnancy and in many of the major pregnancy disorders. We used magnetic resonance imaging techniques to investigate placental function in normal pregnancy, in early and late preeclampsia and in intrauterine growth restriction. READ MORE

  5. 20. Mathematical Simulation of Vehicle-Pedestrian Collisions: Influence of Vehicle Impact Speed and Front-End Structure on the Dynamic Responses of Child and Adult Pedestrians

    Author : Xuejun Liu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; child pedestrian; impact biomechanics; mathematical model; vehicle front-end structure; safety countermeasure; impact speed; parametric study; scaling method;

    Abstract : The development of effective countermeasures for pedestrian protection requires an understanding of how the impact speed and front-end design of the vehicle influence the injury risks of pedestrians. Because of the high involvement of children in pedestrian accidents, there is also a need for child pedestrian mathematical models. READ MORE
