  1. 1. Pedestrian Shoulder and Spine Kinematics and their Influence on Head Kinematics

    Author : Ruth Paas; Chalmers University of Technology; []
    Keywords : PMHS; THUMS; kinematics; spine; head; shoulder; Human Body Model; pedestrian accidents; pedestrian;

    Abstract : Pedestrian to vehicle crashes still represent a major health issue worldwide. In order to prevent fatalities and injuries during the in-crash phase of a pedestrian accident, a sound understanding of pedestrian in-crash kinematics is required and Human Body Models (HBMs) are valuable tools when studying such kinematics.

  2. 2. Sperm Membrane Channels, Receptors and Kinematics : Using boar spermatozoa for drug toxicity screening

    Author : Alejandro Vicente Carrillo; Heriberto Rodríguez-Martínez; Karl-Eric Magnusson; Rudolf Rigler; Vesa Loitto; Stefan Arver; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; Plasma membrane; membrane channels; membrane receptors; kinematics; 3Rprinciples; spermatozoa; boar.;

    Abstract : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. READ MORE

  3. 3. Physical Modeling of Brain and Head Kinematics

    Author : Johan Ivarsson; Chalmers University of Technology; []
    Keywords : brain injury; skull base; rotational acceleration; physical models; lateral ventricles; head kinematics; padding materials; sulci; free motion headform; brain kinematics;

    Abstract : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. READ MORE

  4. 4. Kinematics and fixation of total knee arthroplasties : a clinical, radiographic, scintimetric, and roentgen stereophotogrammetric evaluation

    Author : Kjell G. Nilsson; Johan Kärrholm; Leif Ryd; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total knee arthroplasty; tibial component; kinematics; micromotion; loosening; scintimetry; roentgen stereophotogrammetric analysis;

    Abstract : Aseptic loosening of the tibial component is an important cause of failure after total knee arthroplasty. Bone destruction often claimed to be caused by the cement makes the revision difficult. In order to treat younger patients, uncemented fixation has been introduced, but the etiology to loosening is multifactorial and only partly known. READ MORE

  5. 5. Kinematics and Internal Deformation of Granular Slopes

    Author : Zhina Liu; Hemin Koyi; Dominique Frizon de Lamotte; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; granular flow; kinematics; internal deformation; particle flow method; analogue modeling; natural landslides; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Abstract : Flow-like mass movement is the most destructive landslide and causes loss of lives and substantial property damage throughout the world every year. This thesis focuses on the spatial and temporal changes of the mass movement in terms of velocity and displacement within the failure mass, and the spatial and temporal distribution of the three dimensional internal deformation of the granular slopes using discrete element method, physical experiments, and natural landslides.
