  2. 1. Optical Characterization and Energy Simulation of Glazing for High-Performance Windows

    Author : Andreas Jonsson; Arne Roos; Werner Platzer; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy simulations; antireflection coatings; dip-coating; optical measurements; spectrophotometer; integrating spheres; low-e windows; solar control windows; smart windows; control strategies; U value; g-value; Engineering physics; Teknisk fysik; Engineering Science; teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : This thesis focuses on one important component of the energy system - the window. Windows are installed in buildings mainly to create visual contact with the surroundings and to let in daylight, and should also be heat and sound insulating. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Optical Investigations of Chiral Liquid Crystals

    Author : Anders Dahlgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antiferroelectric; de Vries theory; ferroelectric; optical activity; chiral; dielectric tensor; unwinding; liquid crystal; helicoidal; selective reflection;

    Abstract : Optical investigations of course involve experimental work, but a theoretical basis is also needed. The first chapter can hopefully can give the non-expert an insight into the science of liquid crystals. Liquid crystals are optically birefringent, and a review of the phenomenon of birefringence follows in chapter 2. READ MORE

  6. 4. Colour-changing textile coatings containing multi-layered mica pigments : an experimental study

    Author : Veronica Malm; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mulit-layered mica pigment; effect pigments; angle-dependent color-changes; textile coatings; surface structure; rheology modifiers; coating parameters; Textile Technology; Textiles and Fashion General ; Textil och mode generell ;

    Abstract : This study investigates the possibility of producing angle-dependent colour-changing textiles with thickened polyurethane (PU)-based aqueous dispersion containing multi-layered mica pigments using a direct coating method. Colour changing textile coatings with the latest generation of layered mica pigment (EP) have a promising future for functional purposes such as authentication and aesthetic eye-catching applications.

  7. 5. Appearance of Textured and Pigmented Polymeric Surfaces

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

    Abstract : 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. READ MORE
