  1. 1. Ungdomars användning av dator, internet och mobiltelefon - Konsekvenser för vardagslivets geografiska dimensioner

    Författare :Eva Thulin; Göteborgs universitet; []
    Nyckelord :;

    Sammanfattning : SAMMANFATTNING Syftet med denna rapport är att undersöka hur ungdomar i sin vardag använder sig av olika former av informations- och kommunikationsteknologi (IKT: dator, internet, mobil och fast telefon) och hur användningen påverkar vardagslivets geografiska dimensioner. Dessa dimensioner omfattar dels människors fysiska resor och aktivitetsmönster och dels virtuella kontakter och deras geografiska utsträckning. LÄS MER

  3. 2. Ungdomars virtuella rörlighet. Användningen av dator, internet och mobiltelefon i ett geografiskt perspektiv

    Författare :Eva Thulin; Göteborgs universitet; []
    Nyckelord :ICT use; Internet use; young people; everyday life; virtual mobility;

    Sammanfattning : This study explores how urban young people fit the use of information and communication technologies (ICT) into their everyday lives. Their virtual mobility may be lasting and have long-term effects on socio-spatial structures. LÄS MER

  4. 3. Centrifugal microfluidics-based point of care diagnostics at resource limited settings

    Författare :Ahmad Saleem Akhtar; Aman Russom; Ines Fernandes Pinto; Nicole Pamme; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microfluidics; centrifugal microfluidics; point-of-care; low-cost; diagnostics; agarose beads; immunoassays; colorimetry; fluorescence; cytokines; nucleic acid amplification; isothermal amplification; COVID-19; portable; smartphone; resource limited settings.; Biotechnology; Bioteknologi;

    Sammanfattning : Advancements in medical diagnostics have allowed us to understand the underlying mechanism and treat the root cause for many diseases which had been causing morbidity and mortality up until this point in human history. Furthermore, many of the standard diagnostic procedures have now been transformed to provide answers at or near the point-of-care. LÄS MER

  5. 4. Radio Wave Propagation in Confined Environments - Measurements and Models

    Författare :Henrik Börjeson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radio wave propagation multipath channels loss measurement; Electronics; Elektronik;

    Sammanfattning : This thesis deals with radio wave propagation in environments where the propagation is severely influenced by surrounding objects, mainly walls and other building structures. As an introduction, a brief description is given on propagation terms like loss, delay and dispersion along with system functions relevant for the topic. LÄS MER
