  1. 21. Gamma radiation techniques for non-destructive post-irradiation examination of nuclear fuel : Predicting performance and optimizing instrument design

    Författare :Lorenzo Senis; Peter Andersson; Erik Andersson Sundén; Ane Håkansson; Fabiola Cappia; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Collimated gamma spectroscopy; Gamma emission tomography; Gamma transmission micro-densitometry; Pareto optimization; Post-irradiation examination; Applied Nuclear Physics; Tillämpad kärnfysik;

    Sammanfattning : Collimated gamma-based techniques are widely used to study nuclear fuel, especially for non-destructive post-irradiation examination (PIE). Examples of such techniques include gamma emission tomography (GET) and gamma transmission densitometry (GTD). LÄS MER

  2. 22. Cataract surgery : complications and techniques

    Författare :Anthony Chang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cataract surgery is one of the most common surgical procedures performed worldwide. Posterior capsul opacification (PCO) remains the most common postoperative complication that can deteriorate vision. LÄS MER

  3. 23. Laser Flare Measurements and Kinoform Applications

    Författare :Anna-Karin Holmér; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuchs heterochromic uveitis; kinoform; hot embossing; Nd:YAG; laser machining; laser flare meter; aqueous flare; excimer; retroreflector; traffic signs; diffractive optical element; iris angiography;

    Sammanfattning : This thesis has two main parts. The first part treats the construction and use of a laser flare meter (Papers A and B). The second part deals with applications of kinoforms and consists of the sections "Kinoforms in laser machining" (Papers C and D) and "Diffractive retroreflectors" (Paper E). LÄS MER

  4. 24. Effects of Coherence and Correlations on Transport through Nanostructures

    Författare :Olov Karlström; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2012:Karlström;

    Sammanfattning : This dissertation deals with the effects of coherence and correlations on transport through nanostructures. Simulations are mainly performed using the second order von Neumann approach, a method capable of dealing with these effects in the presence of higher order tunneling. LÄS MER

  5. 25. Shell repair as a response to attempted predation in some Palaeozoic and younger gastropods

    Författare :Anna Lindström; John S. Peel; Jan Ove R. Ebbestad; Euan N. K. Clarkson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Gastropoda; predation; shell morphology; shell repair; Palaeozoic; Geovetenskap; Earth sciences; Geovetenskap;

    Sammanfattning : Traces of unsuccessful predatory attacks can be found in the hard parts of shell-bearing organisms as repaired shell injuries and are often preserved in the fossil record. These repaired shell injuries can help to deduce the relationship between predator and prey in the past. LÄS MER
