  1. 1. Intraocular pressure : clinical aspects and new measurement methods

    Författare :Gauti Jóhannesson; Christina Lindén; Per Hallberg; Anders Eklund; Boel Bengtsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intraocular pressure; glaucoma; tonometry; ISO; LASEK; CCT; curvature; Ophtalmiatrics; Oftalmiatrik; Ophtalmology; oftalmiatrik;

    Sammanfattning : Intraocular pressure (IOP) measurement is a routine procedure and a fundament in glaucoma care. Elevated IOP is the main risk factor for glaucoma, and to date, reduction of IOP is the only possible treatment. In a retrospective clinical material, the prevalence of open angle glaucoma was estimated on the west coast of Iceland. LÄS MER

  3. 2. Cam Roller Contact

    Författare :Frederic Cabanettes; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; classification of surfaces; wear test; roller; rough contact model; surface topography; injection cam; manufacturing evaluation;

    Sammanfattning : The automotive industry and the design of engines are strongly ruled by performance andlegislation demands. First order aspects defining the main functions of a component are wellknown and new challenges appear at a lower scale. LÄS MER

  5. 4. Wheel-rail contact modelling in vehicle dynamics simulation

    Författare :Matin Shahzamanian Sichani; Mats Berg; Roger Enblom; Elena Kabo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; non-elliptic contact; vehicle-track interaction; rail vehicle dynamics; rolling contact; MBS; virtual penetration; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Sammanfattning : The wheel-rail contact is at the core of all research related to vehicle-track interaction. This tiny interface governs the dynamic performance of rail vehicles through the loads it transmits and, like any high stress concentration zone, it is subjected to serious damage phenomena. LÄS MER

  7. 5. Collision Threshold Pressure : A novel measure of voice function Effects of vocal warm-up, vocal loading and resonance tube phonation in water

    Författare :Laura Enflo; Anita McAllister; Johan Sundberg; Marc de Bodt; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The phonation threshold pressure (PTP), i.e., the smallest amount of subglottal pressure needed to initiate and sustain vocal fold oscillation, is frequently difficult to measure due to the difficulty for some subjects to produce extremely soft phonation. In addition, PTP values are often quite scattered. LÄS MER
