  1. 1. Pressure ulcers - role of the nurse to improve patient safety : prevalence, risk factors, classification and documentation in patients undergoing hip surgery

    Författare :Eila Sterner; Bjöörn Fossum; Christina Lindholm; André Stark; Ewa Idwall; Sophiahemmet Högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hip fracture; Pressure ulcers; Classification; Reflectance spectrophotometer; Nursing documentation;

    Sammanfattning : Pressure ulcer is a common complication in hip fracture surgery and convalescence. Earlier prevalence studies have demonstrated a lower prevalence in Southern Europe than in Northern Europe. LÄS MER

  3. 2. Angle dependent light scattering of functional nanoparticle composites

    Författare :JunXin Wang; Gunnar Niklasson; Anand Srinivason; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; light scattering; nano particle; absorption; radiative transfer; Solid State Physics; Fasta tillståndets fysik;

    Sammanfattning : Varies functional nanoparticles play crucial roles in energy- and optical- related applications. The incorporation of functional nanoparticles into non-absorbing polymers to form optical absorption and scattering thin films have attracted considerable interest due to a successful selection of particles and matrices, synergistic effects of separation and fixation of particles, and controllable layer thicknesses and structures.

  4. 3. Appearance of Textured and Pigmented Polymeric Surfaces

    Författare :Sofie Ignell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; appearance; perception; gloss; surface texture; polymer; colour;

    Sammanfattning : The surface appearance is of great importance in the production of high-quality injection-moulded products since it is strongly connected to the quality impression. The surface appearance of any object may be described in terms of colour, gloss and texture. LÄS MER

  5. 4. Optical Characterisation of Miniature Structures and Translucent Sheets for Daylighting Applications

    Författare :Jacob Jonsson; Arne Roos; Helen Rose-Wilson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Photospectrometry; Light scattering; Optical characterisation; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : For a long time spectrophotometry has been a powerful method of determining optical material properties. Since the technique measures the parameters of interest, reflectance and transmittance, it is in general easy to use and interpret. LÄS MER

  7. 5. Appearance of textured and pigmented polymeric surfaces

    Författare :Sofie Ignell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface texture; polymer; gloss; colour; perception; appearance;

    Sammanfattning : The appearance is of increasing importance in the production of premium products since it is strongly connected to the quality impression. The surface appearance of any object may be described in terms of colour and surface characteristics such as gloss and texture. LÄS MER
