  1. 1. Thermal Barrier Coatings Failure Mechanisms and Life Prediction

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Krishna Praveen Jonnalagadda; Linköpings universitet.; Linköpings universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Thermal barrier coatings (TBCs) use in the hot sections of gas turbine engine enables them to run at higher temperatures, and as a consequence, achieve higher thermal efficiency. For full operational exploitation of TBCs, understanding their failure and knowing the service life is essential. READ MORE

  2. 2. Predominant failure mechanisms at the Kiirunavaara mine footwall

    University dissertation from Luleå tekniska universitet

    Author : Mikael Svartsjaern; Luleå tekniska universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : The Luossavaara-Kiirunavaara Aktiebolag (LKAB) Kiirunavaara mine is a large scale sub-level caving (SLC) mine in northern Sweden. The use of SLC as a mining method inherently causes significant rock mass movements above the extraction level. READ MORE

  3. 3. Complement Activation Triggered by Biomaterial Surfaces Mechanisms and Regulation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Andersson; Uppsala universitet.; [2003]

    Abstract : Today there are a vast number of medical devices in temporary or permanent contact with human tissues. Blood-biomaterial contact is known to trigger the complement system and results in generation of fluid phase anaphylatoxins C3a and C5a, and surface-bound C3b and iC3b. READ MORE

  4. 4. Philosophical controversies in the evaluation of medical treatments With a focus on the evidential roles of randomization and mechanisms in Evidence-Based Medicine

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Abstract : This thesis examines philosophical controversies surrounding the evaluation of medical treatments, with a focus on the evidential roles of randomised trials and mechanisms in Evidence-Based Medicine. Current 'best practice' usually involves excluding non-randomised trial evidence from systematic reviews in cases where randomised trials are available for inclusion in the reviews. READ MORE

  5. 5. Gastrointestinal symptoms in chronic renal failure. Prevalence and pathophysiological mechanisms

    University dissertation from Göteborg

    Author : Hans Strid; Göteborgs universitet.; Gothenburg University.; [2003]

    Abstract : Chronic renal failure (CRF) has a varying etiology and is characterised by an increasing accumulation of toxic metabolic waste products in the blood. Malnutrition is a common finding in uraemic patients and is regarded as a marker for morbidity and mortality. Many factors, including gastrointestinal (GI) symptoms, lead to malnutrition in CRF.
