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

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Astrid Linder; [2001]
    Keywords : 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

  2. 2. Early rheumatoid arthritis aspects of severity and co-morbidity

    University dissertation from Umeå : Umeå Universitet

    Author : Lena Innala; Umeå universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Early rheumatoid arthriti; ACPA; cardiovascular co-morbidity; age at onset; pharmacological therapy; severity; disease activity; co-morbidity;

    Abstract : Background Rheumatoid arthritis (RA) is a systemic progressive destructive joint disease with an increased risk for co-morbidity and premature death if untreated. Cardiovascular disease (CVD) is the main cause of death but also other co-morbid conditions contribute to the patient’s shorter life expectancy. READ MORE

  3. 3. Severity of illness versus severity of disease : definitions and applications

    University dissertation from Linköping : Linköpings universitet

    Author : Rosimary Almeida; Linköpings universitet.; Linköpings universitet.; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Abstract : Outcome assessment should consist of two basic steps - "selection of a meaningful outcome" and "determination of what caused the outcome". The latter step requires comparisons, and therefore information about the initial status of the patients. READ MORE

  4. 4. Characteristics of nearside car crashes an integrated approach to side impact safety

    University dissertation from Umeå : Umeå universitet

    Author : Cecilia Sunnevång; Umeå universitet.; [2016]

    Abstract : Introduction: Approximately 1.25 million people globally are killed in traffic accidents yearly. To achieve the UN Global Goal of a 50% reduction of fatal and serious injuries in 2020 a safer infrastructure, as well as new safety technologies, will be needed. Side crashes represent 20% of all serious and 25 % of fatal injuries. READ MORE

  5. 5. Anthropogenic impact on predator guilds and ecosystem processes Apex predator extinctions, land use and climate change

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Marianne Pasanen Mortensen; Stockholms universitet.; [2014]
