  1. 1. Experimental Vitreous Substitution

    Författare :Henrik Barth; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinal Detachment; Vitreous Body : surgery; Retina cytology metabolism surgery; Retina: Function; Retina: Inflammation; Retinal Detachment; Vitreous Body : surgery; Vitreous substitute; Vitrectomy;

    Sammanfattning : Blindness and visual disability are common following vitreoretinal pathologies such as open globe injury, proliferative diabetic retinopathy, and rhegmatogenous retinal detachment (RRD). These conditions often necessitate surgical intervention using vitrectomy with a tamponading vitreous substitute. LÄS MER

  3. 2. Fibroblast growth factor-23 and Klotho in bone/mineral and parathyroid disorders

    Sammanfattning : Fibroblast growth factor-23 (FGF23) is a novel, bone-produced hormone that regulates renal phosphate (Pi) reabsorption and calcitriol metabolism. Disorders of mineral and bone metabolism, such as autosomal dominant hypophosphatemic rickets (ADHR) and hyperostosis-hyperphosphatemia syndrome (HHS), witness the importance of well-balanced serum levels of FGF23.

  4. 3. Experimental investigation of snow metamorphism at near-surface layers

    Författare :Lavan Kumar Eppanapelli; Mikael Sjödahl; Johan Casselgren; Arne Instanes; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Snow metamorphism; NIR reflectance; Snow and Ice; Radiative transfer equation; Paramterization; Snow properties; Tomography; Snow microstructure; Experimentell mekanik; Experimental Mechanics;

    Sammanfattning : Snow metamorphism is a direct objective in many snow research areas, and its charac-terisation is a major challenge in areas including winter road maintenance, detection of icing on wind turbine blades, and snow quality mapping for skiing. A common effect of snow metamorphism is compaction, which can be investigated from the associated vari-ations in physical properties of snow. LÄS MER

    Sammanfattning : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. LÄS MER
