  1. 1. Evaluation of Asphalt Field Cores with Simple Performance Tester and X-ray Computed Tomography

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Florentina Angela Farcas; Björn Birgisson; Xiaohu Lu; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asphalt mixture; dynamic modulus; flow number; simple performance tester; X-ray computed tomography; air voids distribution;

    Sammanfattning : The importance of aggregate structure and air voids distribution for asphalt mixture rutting and cracking performance has been well established on the basis of experience and is well documented in the literature. Past and current investigations are limited to assessment of performance based on macroscopic behavior due to the difficulty associated with the quantitative measurement and analysis of the internal structure of asphalt mixtures.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering mechanics Other engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik Övrig teknisk mekanik;

    Sammanfattning : A project to construct a high-speed road deflection tester was initiated in the 1991. A mid-sized truck was used as a carrier for the first prototype. The results were promising and it was decided to build a full-size truck system. The new vehicle, based on a Scania R143 ML, was completed in 1997. LÄS MER

  3. 3. Lymphedema and Health-Related Quality of Life

    Detta är en avhandling från Lund University: Faculty of Medicine

    Författare :Pia Klernäs; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lymphedema; Sensitivity; Responsiveness; Reliability; Validity; PROM; Questionnaire; Quality of life; Psychometric testing; lymfödem; Livskvalitet; psykometriska tester; reliabilitet; sensitivitet; validitet; responsiveness; enkät;

    Sammanfattning : The overall aim of this thesis was to develop a lymphedema-specific instrument for measuring health-related quality of life (HRQoL) and to evaluate how persons with lymphedema experience HRQoL. Lymphedema is defined as swelling in one or more parts of the body that is due to impaired lymph drainage and transport. LÄS MER

    Sammanfattning : Background It is estimated that 34 million people suffer from dementia, costing society US$422 billion each year. Alzheimer’s disease (AD) is the most common dementia and the global prevalence is predicted to increase to over 100 million people by the year 2050, with the greatest increase in developing countries.
