  1. 1. Surface Plasmon Resonance : Sensitivity and Resolution

    Författare :Knut Johansen; Günter Gauglitz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Surface plasmon resonance (SPR) is a frequently used technique for detection of biomolecular interactions at surfaces. The SPR phenomenon emanates from an electromagnetic surface wave that is exited by a light source. LÄS MER

  3. 2. Dismantling the Conflict Trap : Essays on Civil War Resolution and Relapse

    Författare :Joakim Kreutz; Magnus Öberg; Mats Hammarström; Halvard Buhaug; Barbara F. Walter; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; civil war; conflict resolution; conflict recurrence; diversionary war; ripe moment; natural resources; peace agreement; victory; war termination; Peace and Conflict Research; Freds- och konfliktforskning;

    Sammanfattning : Countries that have experienced civil war suffer a greater risk for new conflict than countries with no prior history of civil war. This empirical finding has been called a conflict trap where the legacy of previous war - unsolved issues, indecisive outcomes, and destruction – leads to renewed fighting. LÄS MER

  4. 3. Tracking Chambers with Two-Dimensional Readout used for Extraction of Particle Production Ratios in High Multiplicity Pb+Pb Collisions at 158 A GeV

    Författare :Tomas Svensson; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy-ion collisions; position resolution; wire chamber pixel readout; pad readout; tracking; multi-step avalanche chamber; Fysik; Physics; particle ratios;

    Sammanfattning : Heavy-ion collisions at high energies calls for new technical solutions to cope with the very high multiplicities of produced particles. In this thesis the design and development of two types of tracking chambers for high multiplicity environments are presented. LÄS MER

  5. 4. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity

    Författare :Aravin Chakravarthi; Funktionell zoologi; []
    Nyckelord :Insect vision; Honeybees; Bumblebees; Spatial resolution; Contrast sensitivity; Motion detection; Object discrimination;

    Sammanfattning : Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. LÄS MER

  7. 5. An Event-Reconstructing Silicon Detector for 1 µm Resolution Spectral Computed Tomography

    Författare :Christel Sundberg; Mats Danielsson; Julia Herzen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photon-counting; silicon detector; spectral computed tomography; subpixel resolution; dose efficiency; coincidence tracking; event reconstruction; fotonräknande; kiseldetektor; spektral datortomografi; subpixelupplösning; doseffektivitet; koincidensspårning; händelserekonstruktion; Fysik; Physics;

    Sammanfattning : Computed tomography (CT) is a medical imaging modality in which cross-sectional images of the human body are created using x-rays. Commercial CT scanners utilize energy-integrating detectors to measure the x-ray attenuation. However, photon-counting detectors with energy-discriminating abilities have started to emerge. LÄS MER
