  1. 1. Characterisation and Consolidation of Historical Lime Mortars in Cultural Heritage Buildings and Associated Structures in East Africa

    Författare :Athuman M. K. Ngoma; Jonas Holmgren; Jan Erik Lindqvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; East Africa; Stone Town; historical building; mortar; deterioration; consolidation; calcium hydroxide solution; Building engineering; Byggnadsteknik;

    Sammanfattning : For the period of several centuries, the influence of several distinct cultures produced rich and diverse cultural heritage that we see today in East Africa countries. The most tangible remains of these heritages are stone built buildings and structures including, palaces, mosques, residential houses and tombs. LÄS MER

  3. 2. Sorption reactions between ionic species and magnetite in aqueous solution

    Författare :Payman Roonasi; Janos Kristof; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : The surface chemistry of inorganic materials is of great significance in a number of industrially important processes such as separation of ore by flotation, catalysis, water purification, leaching, as well as in the formulation of some pharmaceutical preparations. This thesis deals with magnetite and its sorption properties. LÄS MER

  4. 3. Evaluation of endodontic treatment of teeth with apical periodontitis

    Författare :Anders Byström; Göran Sundqvist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endodontic treatment; bacteriological evaluation;

    Sammanfattning : Apical periodontitis, an acute or chronic inflamination around the apex of the tooth, is caused by bacteria in the root canal. In Sweden the dentists devote around 10X of their total time to treating this disease. The treatment usually requires 3 to 5 sessions. The treatment may fail in up to 25X of the cases. LÄS MER

  7. 5. Preparation and Evaluation of New Nanoporous Silica Materials for Molecular Filtration and for Core Materials in Vacuum Insulation Panels

    Författare :Ebenezer Twumasi Afriyie; Folke Björk; Christer Sjöström; Kjartan Gudmundsson; Per Jostein Hovde; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorbents; activated carbon; MgCa-silica; carbon-silica composite; characterization; porous parameters; molecular filtration; thermal conductivity; thermal insulation;

    Sammanfattning : Nanoporous materials for gas purification and thermal insulation have been studied and developed for application in many areas. It is known that a single adsorbent may not adequately control multiple contaminants. Further the utilization of nanoporous material as thermal insulator in building applications is limited due to high cost. LÄS MER
