  1. 1. Förnuftets brytpunkt : om teknikkritiken i P C Jersilds författarskap

    Författare :Jonas Anshelm; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Technology criticism; Technological society; Rationality; Reason; Morality; Narratives; Swedish literature; P C Jersild; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Modern technology has enabled us to realise objectives our forebearers could only dream of. Our capacity to do both good and evil has grown dramatically. With these new capacities ensue extremely weighty moral responsibilities.P C Jersild is a Swedish author who has dedicated his work to the investigation of morality in the technological society.

  3. 2. Dispersion Engineering : Negative Refraction and Designed Surface Plasmons in Periodic Structures

    Författare :Zhichao Ruan; Min Qiu; Henri Benisty; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic crystal; dispersion property; negative refraction; surface plasmon polariton; designed surface plasmon; negative index material; layer-KKR method; finite-difference time-domain method; plane wave method; subwavelength imaging; open cavity; enhanced transmission; slowing light; Photonics; Fotonik;

    Sammanfattning : The dispersion property of periodic structures is a hot research topic in the last decade. By exploiting dispersion properties, one can manipulate the propagation of electromagnetic waves, and produce effects that do not exist in conventional materials. LÄS MER

  4. 3. Glaucoma Characteristics and Risk Factors - Results from Malmö Eye Survey

    Författare :Kirsti Grødum; Oftalmologi (Malmö); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vascular disease; Ophtalmology; Oftalmologi; myopia; optic disc hemorrhages; mortality; refraction; glaucoma; population screening;

    Sammanfattning : This thesis is based on data from a large glaucoma screening, comprising 32, 918 elderly citizens of Malmö and data from retrospective analysis of glaucoma patients’ charts from the Eye Department of Malmö University Hospital. The definition of glaucoma was based on reproducible visual field defects and/or glaucomatous optic nerve head damage in both groups. LÄS MER

  5. 4. Ophthalmological follow-up in young adults born premature and screened for retinopathy of prematurity

    Författare :Dýrleif Pétursdóttir; Eva Larsson; Gerd Holmström; Marita Andersson Grönlund; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long-term follow-up; prematurity; refraction; retinopathy of prematurity; strabismus; visual function; visual-motor integration; young adults; Ophtalmology; Oftalmiatrik;

    Sammanfattning : Prematurely born children have a higher risk of ophthalmological and neurodevelopmental disorders than those born at term. There is a paucity of long-term prospective follow-up studies on the visual function of prematurely born adults. LÄS MER

  7. 5. Wind Turbine Sound Propagation in the Atmospheric Boundary Layer

    Författare :Olof Öhlund; Conny Larsson; Anna Sjöblom; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wind turbine sound; atmospheric effects; outdoor sound propagation; refraction;

    Sammanfattning : Wind turbines have grown both in size and number in the past decades. The taller turbines has made it possible to place them in forest areas which is fortunate for a country like Sweden with lots of forest. An issue with wind turbines is the sound they produce. The sound mainly comes from the rotor blades when they pass through the air. LÄS MER
