2. 21. Ocular counter-rolling during head tilt

   Author : Tony Pansell; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Eye movements; Ocular torsion; VOR; head tilt; Vision.;

   Abstract : When tilting the head towards the shoulder there are numerous mechanisms influencing on the generation and maintenance of ocular counter-roll. Each of these mechanisms has its own temporal and spatial characteristics which influences on the counter-rolled eye position. READ MORE

4. 22. Biomolecular markers in head and neck cancer

   Author : Eva Lindell Jonsson; Göran Laurell; Karin Nylander; Marika Nestor; Linda Marklund; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Head and neck cancer; Biomolecular markers; Radiation; Radiation-induced mucositis; Oral Tongue Squamous Cell Carcinoma; Metabolomics; EGFR; Hyaluronan; Mast cells; Neutrophils; Oto-Rhino-Laryngology; Oto-rhino-laryngologi;

   Abstract : Head and neck cancer is a heterogeneous group of tumours, of which certain subgroups such as cancer of the mobile tongue frequently are associated with a relatively poor prognosis due to the high risk of regional failure and mortality rates that haven’t improved in a significant way over the last 3 decades, despite advancements in both diagnostics and treatment.Today we lack means to assess the biological aggressiveness of each individual tumour, which varies largely.

5. 23. Initial Studies of Dynamic Responses of Female and Male Volunteers in Rear Impact Tests

   Author : Anna K Carlsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic response; rear impact; response corridors; volunteers; crash test; neck injury; whiplash; females;

   Abstract : Whiplash Associated Disorder (WAD) - commonly denoted whiplash injury - resulting from vehicle impacts, is a worldwide epidemic. These injuries occur at relatively low changes of velocity (typically between 10-25 km/h) and in impacts from all directions. Rear impacts are however the most common in the accident statistics.

   Abstract : Background: Treatment for head and neck cancer (HNC) is often multimodal, including surgery, radiotherapy, and chemotherapy. The anatomic location of HNC and its treatments often affect vital functions such as swallowing and speech, but also physical appearance, leading to a risk for social withdrawal and nutritional difficulties that can affect the patient’s quality of life.

7. 25. Neck injuries in rear impacts : Dummy neck development, dummy evaluation and test condition specifications

   Author : Astrid Linder; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neck; Injury; Anthropometric dummy; Severity; Impact test; Rear end collision; Seat; Mathematical model; Velocity; Thesis; Optimization; Mathematical neck models; Rear impact tests; Biomechanics; Road: Components of the vehicle; Road: Components of the vehicle;

   Abstract : The objective of the work underlying this thesis was firstly to develop a neck for a new rear impact dummy, to evaluate the complete dummy and to specify test conditions for a consumer test with attention to AIS 1 neck injuries in rear impacts. In the development of the dummy neck, a mathematical neck model was developed and evaluated. READ MORE
