  2. 11. System analysis of a PV/T hybrid solar window

    Author : Henrik Davidsson; Institutionen för arkitektur och byggd miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar window; PV T hybrid; building integration; TRNSYS;

    Abstract : A building-integrated multifunctional PV/T solar window was suggested and developed by Andreas Fieber. The solar window is constructed of PV cells laminated on solar absorbers placed in a window behind the glazing. READ MORE

  4. 12. Solar Assisted Pervaporation : A process for the concentration of fruit juices in membrane pouches with solar energy

    Author : Randi Phinney; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pervaporation; solar drying; membrane pouch; juice concentration; fruit preservation; marmalade; tangerine; Vangueria infausta; microbiology; water activity; soluble solids; Brix;

    Abstract : Drying has been used for thousands of years to preserve foods. One of the first methods used was open air sun drying which exposes foods directly to solar radiation and ambient air. This method is still used today around the world but it remains underdeveloped on a small-scale for two main reasons. READ MORE

  5. 13. Thermal Radiation from Co-evaporated Cu(In,Ga)Se2 : End point detection and process control

    Author : Jens Schöldström; Marika Edoff; Nicolas Barreau; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; CIGS; Cu InGa Se2; thin film; solar cells; end point detection; process control; optical constants; CuxSe; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : The use of solar cells for energy production has indeed a bright future. Reduction of cost for fabrication along with increased efficiency are key features for a market boom, both achieved as a result of increased knowledge of the technology. READ MORE

  6. 14. Molecular responses of plants to solar UV-B and UV-A radiation

    Author : Luis Orlando Morales; Pedro José Aphalo; Mikael Brosché; Riitta Tegelberg; Nigel Paul; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi;

    Abstract : Plant responses to solar ultraviolet radiation (UV, 280-400 nm) were assessed at different molecular levels using Betula pendula Roth (silver birch) and Arabidopsis thaliana (Arabidopsis) as model species in outdoor experiments to assess the possibly interacting roles of the UV-B and UV-A wavebands in acclimation to sunlight. Solar UV-B (280-315 nm) and UV-A (315-400 nm) irradiance was attenuated with plastic films. READ MORE

  7. 15. Climate Related Thermal Actions for Reliable Design of Concrete Structures

    Author : Oskar Larsson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal stress; solar radiation; FE-analysis; climate data; box-girder bridge; KstrConcrete; KstrReliability;

    Abstract : When the temperature changes in the environment the temperature will also change in a structure. Complex interactions of climate factors affect the temperature changes. When the temperature is varied in a material it will expand or contract, and movements will be produced. READ MORE
