  1. 1. Fatigue och återhämtning efter hjärtinfarkt

    Detta är en avhandling från Göteborg : Institutionen för vårdvetenskap och hälsa vid Sahlgrenska akademin, Göteborgs universitet

    Författare :Ulla Fredriksson-Larsson; Högskolan Väst.; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vårdvetenskap; Nursing science; Coping strategies; fatigue; grounded theory; myocardial infarction; nursing; person-centeredness; psychometric evaluation; Rasch analysis; stress; symptom assessment; symptom experience; symptom research; The Multidimensional Fatigue Inventory-20 MFI-20 ; Fatigue; Myocardial infarction; Symptom experience; Psychometric evaluation;

    Sammanfattning : Fast and efficient acute medical treatment of myocardial infarction (MI) has developed during recent years and has resulted in a reduced number of days spent in hospital and increased survival. To optimize persons’ recovery, secondary preventive strategies are important. LÄS MER

  2. 2. Very high cycle fatigue of high performance steels

    Detta är en avhandling från Karlstad : Karlstad University

    Författare :Vitaliy Kazymyrovych; Karlstads universitet.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Materials Engineering; fatigue; tool steels; ultrasonic testing; fatigue life; crack growth rate; fatigue mechanisms;

    Sammanfattning : Many engineering components reach a finite fatigue life well above 109 load cycles. Some examples of such components are found in airplanes, automobiles or high speed trains. For some materials the fatigue failures have lately been found to occur well after 107 load cycles, namely in the Very High Cycle Fatigue (VHCF) range. LÄS MER

  3. 3. Fatigue strength of engineering materials the influence of environment and porosity

    Detta är en avhandling från Stockholm : KTH

    Författare :Jan Linder; KTH.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; cast aluminium; hardened steels; fatigue; corrosion; crack propagation; spot weld; porosity; TECHNOLOGY Materials science Other materials science; TEKNIKVETENSKAP Teknisk materialvetenskap Övrig teknisk materialvetenskap;

    Sammanfattning : The objective of this work was to use LEFM in order to assess the detrimental influence of surrounding chloride-containing environments for stainless steels, hardened steel as well as for a cast aluminium alloy. An additional aim was also to use LEFM to assess the influence of porosity on the fatigue properties for different commercial cast aluminium alloys and manufacturing methods. LÄS MER

  4. 4. Fatigue after traumatic brain injury exploring novel methods for diagnosis and treatment

    Detta är en avhandling från Umeå : Umeå University

    Författare :Nils Berginström; Umeå universitet.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; fatigue; OSU6162; randomized clinical trials; functional magnetic resonance imaging; neuropsychology; structural magnetic resonance imaging; white matter hyperintensities; rehabiliteringsmedicin; Rehabilitation Medicine;

    Sammanfattning : Background: Traumatic brain injury (TBI) is one of the most common causes of disability and mortality. While some patients recover quickly, especially at the mild side of the injury severity continuum, many will experience symptoms for years to come. LÄS MER

  5. 5. Fatigue Assessment of Cast Components Influence of Cast Defects

    Detta är en avhandling från Stockholm : KTH

    Författare :Anders Björkblad; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cast nodular iron; fatigue; design rules; fracture mechanics; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Sammanfattning :  This thesis is on the fatigue assessment of cast components with special attention to defects. The primary material in view is nodular cast iron, but also cast steel is considered. However, the fatigue behaviour is in principle valid for general use on other cast metals. LÄS MER
