  4. 12. Spatially resolved gas sensing

    Author : Mikael Löfdahl; Werner Moritz; Linköpings universitet; []
    Keywords : ;

    Abstract : By using a Scanning Light Pulse Technique (SLPT) the gas response of catalytic Metal-Insulator semiconductor (MIS) devices can be spatially resolved.The application of SLPT to gas sensitive MIS devices can be divided into two areas. READ MORE

  5. 13. The Palaeopathology of Kirchberg : Evidence of Deficiency, Inflammatory and Tumorous Disease in a Medieval Rural Population in Hessia, Germany

    Author : Nikolaos Roumelis; Jan Storå; Michael Schultz; Pia Bennike; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Kirchberg; rural population; Middle Ages; palaeohistopathology; palaeopathology; microscopy; diagnosis; health; inflammatory disease; tumorous disease; micrometastases; deficiency disease; environment.; Archaeology; Arkeologi; osteoarkeologi; Osteoarchaeology;

    Abstract : This study investigates the interaction of disease processes, disease and environment, female and male health as well as health and ageing in a medieval rural village population. For this purpose multiple skeletal indicators of health have been studied, including deficiency, inflammatory, infectious and tumorous disease. READ MORE

  6. 14. Partial Discharges Studied with Variable Frequency of the Applied Voltage

    Author : Hans Edin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diagnostic methods; partial discharges; phase resolved; variable frequency; dielectric spectroscopy; dielectric response; harmonics; insulation; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : This thesis concerns partial discharge (PD) diagnostics withvariable frequency of applied voltage in the frequency range 1mHz - 400 Hz. The exploration of a new type of spectroscopythat combines partial discharge analysis and dielectricresponse is demonstrated. READ MORE

  7. 15. Epithelial stem cells in Hutchinson-Gilford progeria syndrome

    Author : Tomás McKenna; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Hutchinson-Gilford progeria syndrome (HGPS) and restrictive dermopathy (RD) are two rare genetic disorders that affect children. Complications from cardiovascular disease, including atherosclerosis, are the most common cause of death in HGPS, which occurs at around 13 years of age. READ MORE
