    Sammanfattning : Boreal forests are particularly vulnerable to climate change, experiencing a much more drastic increase in temperatures and having a limited amount of more northern refugia. The trees making up these vast and important ecosystems already had to adapt previously to environmental pressures brought about by the repeated glaciations during past ice ages. LÄS MER

  3. 12. Noll tolerans mot hot och våld inom ambulanssjukvården : en litteraturstudie

    Magister-uppsats, Sophiahemmet Högskola

    Författare :AnnSofie Thorstenson; Mimmi Eriksson; [2022]
    Nyckelord :Ambulance; Experience; Nursing Care; Prehospital; Threat Violence; Ambulans; Ambulanssjukvård; Hot och Våld; Erfarenhet; Omvårdnad;

    Sammanfattning : Bakgrund: Hot och våld förekommer i alla delar av vården och det speglar ett hårdare klimat i samhället och framförallt inom akutsjukvården. Ambulanspersonalen arbetar patientnära och är extra utsatta i både ensamarbete och i komplexa situationer. LÄS MER

  4. 13. Studies on Reverse Engineering of Constant Frequence Geometric Quantum Gates

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Wu Zijin; [2022]
    Nyckelord :;

    Sammanfattning : Geometric Quantum Computation (GQC) is one of the effective methods to realizequantum computation. By using geometric phases, it shows robustness to certainerrors. This thesis aims to develop a new systematic technique for implementing GQC,especially in non-adiabatic systems. LÄS MER

  5. 14. Safety and Stability of Samples Stored on Filter Paper for Molecular Arbovirus Diagnosis

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Emelie Bringeland; [2021]
    Nyckelord :Arthropod-borne viruses arboviruses ; alphaviruses; flaviviruses; dengue virus DENV ; Japanese encephalitis virus JEV ; Tick-borne encephalitis virus TBEV ; Usutu virus USUV ; Zika virus ZIKV ; Flinders Technology Associates™ card FTA ; Biosafety; Vietnam;

    Sammanfattning : Expanding urbanization, climate change, and population growth contribute to increased transmission and spread of arthropod-borne viruses (arboviruses), many of which cause severe disease in humans. Pathogenic arboviruses include dengue, Zika, tick-borne encephalitis, and sindbis viruses, which together threaten more than half the global population. LÄS MER

  7. 15. Adiabatisk genväg till quditberäkning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Kellen Smith; [2021]
    Nyckelord :adiabatic shortcut; qudit; quantum computation; logic gate; holonomy; geometric phase; robust gates;

    Sammanfattning : One of the major challenges hindering advancement of quantum computing is the sensitive nature of the physical systems used to build a quantum computer. One suggestion for improving reliability is a particular type of logic gates, based on Berry's geometric phase, showing improved robustness to external disturbance of the quantum system over the course of a calculation.
