    Nyckelord :bus crash; major road traffic crash; survivors; injuries; consequences; experiences; recovery; social support; emergency care; compassionate care; long-term recovery;

    Sammanfattning : Background Major road traffic crashes (RTCs) can have a significant impact on the survivors, their family, and their friends, as well as on emergency personnel, volunteers, and others involved. However, survivors’ perspectives are rare or missing in research on major RTCs in Sweden. LÄS MER

  3. 17. Evolution of HIV-1 coreceptor use in relation to pathogenesis

    Författare :Ingrid Karlsson; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; RANTES; higly active antiretroviral therapy; pathogenesis; lymphoid tissue; cehmokine receptor; biological phenotype; coreceptor; HIV-1; evolution;

    Sammanfattning : HIV-1 uses the coreceptors CCR5 and/or CXCR4 in addition to CD4 to enter the host cell. CCR5-using HIV-1 (R5 phenotype) appears to transmit infection and usually dominates the early stages of disease. LÄS MER

  4. 18. Posttraumatic Stress Reactions in Tortured Refugees : Relationship to pain, cognitive impairments, and negative appraisals

    Sammanfattning : Refugees, particularly those exposed to torture and other forms of organized violence, often experience a wide range of difficulties, including posttraumatic stress disorder (PTSD), depression, and somatic disturbances, particularly pain. Multimodal treatments have been developed to target this comorbidity in refugees, with evidence suggesting they are moderately effective. LÄS MER

  5. 19. Stealthy Sensor Attacks on Feedback Systems : Attack Analysis and Detector-based Defense Mechanisms

    Författare :David Umsonst; Henrik Sandberg; Hideaki Ishii; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In this thesis, we investigate sensor attacks on feedback systems and how anomaly detectors can be used as a defense mechanism. We consider an attacker with access to all sensor measurements and full knowledge about the closed-loop system model. LÄS MER

  7. 20. Mathematics and mathematics education - two sides of the same coin : creative reasoning in university exams in mathematics
