  2. 1. Studies on the use of digital radiography for the assessment of periapical bone lesions

    Author : Boel Kullendorff; Helsingborg Kliniska Vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; subtraction radiography; image processing; Digital radiography; dental radiography; Odontology; stomatology; Odontologi;

    Abstract : The aim was to study digital radiography and to evaluate the influence of image processing on digital dental radiographs for the assessment of periapical lesions. In four studies, artificial bone lesions were made periapically and interradicularly in the mandibular premolar and molar regions. READ MORE

  4. 2. An Experimental Study on the Dynamics of a Single Droplet Vapor Explosion

    Author : Roberta Concilio Hansson; Weimin Ma; Geroges Berthoud; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; steam explosions; radiography; melt preconditioning; noncondensable gas; Low energy physics; Lågenergifysik;

    Abstract : The present study aims to develop a mechanistic understanding of the thermal-hydraulic processes in a vapor explosion, which may occur in nuclear power plants during a hypothetical severe accident involving interactions of high-temperature corium melt and volatile coolant. Over the past several decades, a large body of literature has been accumulated on vapor explosion phenomenology and methods for assessment of the related risk. READ MORE

  5. 3. An experimental study on the dynamics of melt-water micro-interactions in a Vapor explosion

    Author : Roberta Concilio Hansson; Truc-Nam Dinh; Daniel Magallon; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik;

    Abstract : Vapor explosion as a result of Molten Fuel-Coolant Interactions (MFCI) postulated to occur in certain severe accident scenarios in a nuclear power plant presents a credible challenge on the plant containment integrity. Over the past several decades, a large body of literature has been accumulated on vapor explosion phenomenology and methods for assessment of the related risk. READ MORE
