  2. 1. On Biogenic Halocarbons in Antarctic Waters

    Author : Erik Mattsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Volatile biogenic halocarbons; Antarctica; Southern Ocean; Sea ice; Snow; Air-sea exchange;

    Abstract : Little is known regarding the distribution of naturally produced volatile halogenated organic compounds, halocarbons, in Antarctic waters and the contribution of these waters to the global atmospheric load of halogens. In the atmosphere, halocarbons are degraded by photolysis, and form reactive halogen radicals. READ MORE

  4. 2. Approaches to road network vulnerability analysis

    Author : Erik Jenelius; Lars-Göran Mattsson; Kurt Petersen; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Other social sciences; Övrig samhällsvetenskap;

    Abstract : Incidents in the road transport system can have large negative consequences for the society and the business community. The basic aim of vulnerability analysis is to identify scenarios that i) would lead to severe consequences, and ii) have some likelihood of being realized in the future. READ MORE

  5. 3. Design, Fabrication and Optimization of Thermal Radiation Detectors Based on Thin Polymer Membranes

    Author : Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Ylva Bäcklund; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detector; Polymer; Membrane; SU-8; Electronics; Elektronik;

    Abstract : The number of applications in which infrared radiation sensors are used is increasing. In some applications, the cost of the sensor itself is an issue, and simple solutions are thus required. In this thesis, the investigations have related to the use of thin polymer membranes in thermal infrared sensors, such as bolometers and thermopiles. READ MORE

  6. 4. Fabrication and Characterization of Photon Radiation Detectors

    Author : Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Mikael Lindeberg; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Detectors; Posistion Sensitive Detectors; Electronics; Elektronik;

    Abstract : This thesis involves a study the fabrication and characterization of photon radiation detectors. The focus has been to develop and improve the performance of optical measurement systems, but also to reduce their cost. The work is based on the study of two types of detectors, the position sensitive detector and the thermal detector. READ MORE

  7. 5. Health-related Internet use and screening for emotional distress in people with cancer

    Author : Susanne Mattsson; Johansson Birgitta; Maria Carlsson; Erik Olsson; Ann Langius-Eklöf; Uppsala universitet; []
    Keywords : Social support; Internet; Cancer; eHealth; Questionnaire; Oncology; Support; Patient preference; Screening; Depression; Anxiety;

    Abstract : The overall aim of this thesis was to investigate the preferences and incentives for using Internet-delivered support among people with cancer and to develop and test a generic questionnaire measuring health-related Internet use, the Health Online Support Questionnaire (HOSQ). Another aim was to examine the psychometric properties of the online-administered Hospital Anxiety and Depression Scale (HADS) and Visual Analogue Scale (VAS) regarding anxiety and depression in psychosocial screening among people with cancer, in comparisons with the longer instruments Montgomery Åsberg Depression Rating Scale – Self-report (MADRS-S) and the State Trait Anxiety Inventory – State (STAI-S).
