  1. 21. Ultrasound measurement of cervical length in the second trimester of pregnancy for prediction of preterm delivery

    Författare :Pihla Kuusela; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preterm delivery; transvaginal ultrasound; cervical length measurement; second trimester; prospective study; observational study; mass screening; reproducibility of results; inter-observer variation; intra-observer variation; data accuracy; quality control;

    Sammanfattning : Abstract Background: Short cervical length is a risk factor for preterm delivery (PTD) and screening of cervical length using transvaginal ultrasound in the second trimester is a proposed method to find women at risk Aims: To examine the potential value of routine measurement of cervical length in a Swedish population of women with singleton pregnancies in the prediction of PTD. To estimate inter- and intra-observer agreement and reliability of cervical length measurements. LÄS MER

  3. 22. Placental pathology regarding inflammation and a new classification of stillbirth

    Författare :Ingela Hulthén Varli; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: The incidence of stillbirth has remained almost constant during the last 2-3 decades despite obvious improvements in obstetric care. To achieve a reduction of stillbirth, better understanding of the etiology is imperative. Relevant test protocols and audit work is reported to reduce the number of unexplained cases. LÄS MER

  4. 23. Millimeter-Wave High-Gain Antenna for 5G Backhauling with Auto-beam-tracking Function

    Författare :Enlin Wang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gap waveguide; auto-beam-tracking; 5G backhaul; Ultra-high-gain antenna; me- chanical movement;

    Sammanfattning : As microwave links are increasingly deployed within the millimeter-wave frequency range, E-band (70/80 GHz) links have been installed on a global scale. One major technological challenge in this high-frequency spectrum is the significant increase in path loss between receivers and transmitters. LÄS MER

  7. 25. Demand response and distributed solar generation in the Swedish residential sector - A techno-economic evaluation

    Författare :Emil Nyholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand response; Distributed solar generation;

    Sammanfattning : There is an urgent need to transform the electricity system so as to reduce greenhouse gas emissions. Among the possible pathways for such a transformation, the demand side of the electricity system is likely to take a more active role than it has historically. LÄS MER
