  1. 26. Position Sensitive Detectors : Device Technology and Applications in Spectroscopy

    Författare :Henrik Andersson; Hans-Erik Nilsson; Göran Thungström; Jan Linnros; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Position sensitive detectors; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : This thesis deals with the development, processing and characterization of position sensitive detectors and, in addition, to the development of compact and cost effective spectrometers. Position sensitive detectors are used to measure, with great accuracy and speed, the position of a light spot incident on the surface. LÄS MER

  3. 27. The Clinical Appearance of Pelvic Inflammatory Disease in Relation to Use of Intrauterine Device in Latvia : A Study with Special Emphasis on Factors Influencing the Clinical Course of PID in IUD Users

    Författare :Ilze Viberga; Viveca Odlind; Gunilla Lindmark; Babill Stray-Pedersen; Uppsala universitet; []
    Nyckelord :Medical sciences; pelvic inflammatory disease; complicated pelvic inflammatory disease; contraception; intrauterine device; reproductive history; microbiology; anaerobes; surgery; gynecologist; practice; MEDICIN OCH VÅRD; MEDICINE; MEDICIN;

    Sammanfattning : The objectives of this case-control study, investigating 51 in-patient women with acute pelvic inflammatory disease (PID) and 50 healthy women attending for routine gynecological check-up, were to investigate the background and reproductive history of women, who are considered at low risk of sexually transmitted infection presenting with PID, to examine whether intrauterine device (IUD) use per se and long use affects the microbiology and clinical course of the disease, to identify risk factors for PID and to examine whether IUD use is an independent risk factor for PID.The most striking difference regarding the background and reproductive history between women with PID and healthy women over age 25 were related to socio-demographic factors and not to common risk factors for PID.
