  1. 6. CFRP Strengthening of Cut-Out Openings in Concrete Walls – Analysis and Laboratory Tests

    Författare :Cosmin Popescu; Björn Täljsten; Gabriel Sas; Thomas Blanksvärd; Stijn Matthys; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Redesigning buildings to improve their space efficiency and allow changes in use is often essential during their service lives to comply with shifts in living standards and functional demands.This may require the introduction of new openings in elements such as beams, walls, and slabs,which inevitably reduces their structural performance and hence requires repair or strengthening.

  3. 7. The air distribution in buildings with combined natural and mechanical ventilation

    Författare :Gunnar Åhlander; KTH; []
    Nyckelord :;

    Sammanfattning : This work describes result from both measurements on anumber of one family houses, an analytical study of a one-zonemodel and multi zone studies of a two storey building. Thesimulations are performed as both parametric studies, withcombined values of outside temperature, wind velocity and winddirection, and whole year simulations. LÄS MER

  4. 8. Synthetic studies on naphthoxylosides - labeled compounds and mechanistic studies on acetals

    Författare :Richard Johnsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fluorescent xylosides; Carbohydrates; Naphthoxylosides; Cancer; Mechanistic studies; Radioactive xylosides; Acetals;

    Sammanfattning : Labeled analogs to an antiproliferative naphthoxyloside have been synthesized and evaluated. Our investigations have shown that the fluorescently labeled analogs are poor structural analogs, and the physical and biological properties are altered to a large extent. LÄS MER

  5. 9. Selective Epitaxy of Indium Phosphide and Heteroepitaxy of Indium Phosphide on Silicon for Monolithic Integration

    Författare :Fredrik Olsson; Sebastian Lourdudoss; Shigeya Naritsuka; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semiconductor Physics; Semiconductor physics; Halvledarfysik;

    Sammanfattning : A densely and monolithically integrated photonic chip on indium phosphide is greatly in need for data transmission but the present day’s level of integration in InP is very low. Silicon enjoys a unique position among all the semiconductors in its level of integration. LÄS MER

  7. 10. Physico-Chemical Investigations of Bilayer Discs and Related Lipid Structures Formed in Liposomal Systems Intended for Triggered Release

    Författare :Maria Sandström; Katarina Edwards; Mats Almgren; Tommy Nylander; Uppsala universitet; []
    Nyckelord :Physical chemistry; liposome; triggered release; pH-sensitive liposomes; temperature-sensitive liposomes; drug partitioning; cryo-TEM; discs; Fysikalisk kemi;

    Sammanfattning : This thesis describes results from fundamental studies of liposomes intended for drug delivery and pH or temperature triggered release. In addition, the effect of lipid composition on bilayer disc formation and a potential application of the bilayer discs were investigated. LÄS MER
