  1. 1. Service Life Assessment of Harbor Structures - Case studies of chloride ingress into concrete and sheet piling corrosion rates

    Författare :Henrik Wall; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chloride ingress; sampling methods; corrosion rates; sheet piling; ultra-sonic measurements; service life; durability; quay structures; harbor structures;

    Sammanfattning : The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where the steel sheet pile walls often have cap beams of reinforced concrete. LÄS MER

  3. 2. Passive sampling of PAHs and some trace organic compounds in occupational and residential air: needs, evaluation and limits

    Författare :Pernilla Bohlin; Göteborgs universitet; []
    Nyckelord :passive air sampling; PAH; POP; occupational environment; residential environment; exposure; stationary air sampling; personal air sampling; PUF; evaluation;

    Sammanfattning : Human exposure to elevated levels of polycyclic aromatic hydrocarbons (PAHs) and trace organic compounds (e.g. PCB, OCP, PBDE) can be related to negative health effects. This raises demands of exposure measurements to be performed. LÄS MER

  4. 3. CMOS Parallel-Sampling Receivers

    Författare :Henrik Johansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : As the processing capacity of the microelectronic circuits increases, the demands on the interconnects will also increase. Hence, there is a need for higher bandwidth to the chips. This dissertation discusses the possibilities to improve the input data rate to CMOS integrated circuits, which is the most common integrated circuit technology today. LÄS MER

  5. 4. Multiband LNA Design and RF-Sampling Front-Ends for Flexible Wireless Receivers

    Författare :Stefan Andersson; Christer Svensson; Marc Tiebout; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RF; Microelectronics; Multiband LNAs; RF-Sampling; Sampling Front-Ends; Flexible Wireless Receivers; Multistandard Receivers.; Electronics; Elektronik;

    Sammanfattning : The wireless market is developing very fast today with a steadily increasing number of users all around the world. An increasing number of users and the constant need for higher and higher data rates have led to an increasing number of emerging wireless communication standards. LÄS MER

  7. 5. Self-sampling for HPV testing in primary cervical screening : Including clinical and health economic aspects

    Författare :Riina Aarnio; Matts Olovsson; Ulf B. Gyllensten; Ingrid Wikström; Christer Borgfeldt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HPV; self-sampling; cervical screening; CIN2 ; cost-effectiveness; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Persistent infection with high-risk human papillomavirus (HPV) is a prerequisite for the development of cervical cancer. HPV testing has higher sensitivity for high-grade cervical intraepithelial neoplasia (CIN2+) than cytology, resulting in more effective screening. LÄS MER
