  1. 1. Materiella vändningar läsningar av Parland, Lispector, Berg och Byggmästar

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Jenny Jarlsdotter Wikström; Maria Jönsson; Elisabeth Friis; Sven Anders Johansson; Amelie Björck; [2020]

    Sammanfattning : The aim of the dissertation is to examine the analytical potential of  the ”material turn” within the field of literary studies. In particular, it explores how theoretical perspectives associated with the material turn may shed light on the work of four writers: Henry Parland (Finland, 1908–1930), Clarice Lispector (Brazil, 1920–1977), Aase Berg (Sweden, b.

  2. 2. In the quest for a cold tolerant variety : gene expression profile analysis of cold stressed oat and rice

    Detta är en avhandling från Göteborgs universitet

    Författare :Angelica Lindlöf; Högskolan i Skövde.; Högskolan i Skövde.; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Other biology Bioinformatics; NATURVETENSKAP Biologi Övrig biologi Bioinformatik; Teknik; Technology; cold tolerance; oat; rice; bioinformatics analysis;

    Sammanfattning : Cold acclimation is a process which increases the freezing tolerance of an organism, after exposure to low, non-freezing temperatures. The acclimation ensures that cold tolerant species can endure harsh winter conditions, by preparing them to sub-zero temperatures. LÄS MER

  3. 3. Operationssjuksköterskans vårdande och kompetens inom perioperativ vård

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Ann-Catrin Blomberg; Karlstads universitet.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; operating theatre nurse; perioperative nursing; responsibility; competence; hermeneutics; mixed methods; ansvar; hermeneutik; klinisk kompetens; mixad metod; operationssjuksköterska; perioperativ vård; PROFFNurse SAS; Nursing Science; Omvårdnad;

    Sammanfattning : The overall aim was to describe and deepen the understanding of what operating theatre nurses experience as caring and responsibility as well as ethical problems in perioperative practice. The aim was also to investigate how operating theatre nurses perceive clinical competence in perioperative nursing. LÄS MER

  4. 4. Very high cycle fatigue of duplex stainless steels and stress intensity calculations

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Muhammad Waqas Tofique; Karlstads universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Very high cycle fatigue; duplex stainless steel; ultrasonic fatigue testing; distributed dislocation dipole technique; Materialteknik; Materials Engineering;

    Sammanfattning : Very high cycle fatigue (VHCF) is generally considered as the domain of fatigue lifetime beyond 10 million (107) load cycles. Few examples of structural components which are subjected to 107-109 load cycles during their service life are engine parts, turbine disks, railway axles and load-carrying parts of automobiles.

  5. 5. Very high cycle fatigue of automotive steels Testing and computation at 20 kHz

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Mohamed Sadek; Karlstads universitet.; [2020]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Very high cycle fatigue; ultrasonic fatigue testing; automotive steels; fatigue strength; stress intensity computation; crack growth; Materialteknik; Materials Engineering;

    Sammanfattning : Mechanical fatigue failure occurs in components subjected to cyclic loading. A crack initiates at critical regions in the component and propagates during repeated loading. The expected fatigue life depends on the level, type and frequency of the loading. LÄS MER
