  1. 1. Geotechnical Aspects of Buildings on Expansive Soils in Kibaha, Tanzania : Preliminary Study

    Author : Charles Lucian; Staffan Hintze; Bo Berggren; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; expansive soils; soil properties; potential swell; Soil-Structure Interaction SSI ; and superstructure and substructure.; Building engineering; Byggnadsteknik;

    Abstract : The focus of this study is on potential problems resulting from construction on expansive soils in Kibaha region, Tanzania. For the fact that most of the affected structures are founded on expansive soils, a clear understanding of the soil behaviour and their interaction with structures, specifically as they relate to shallow foundations, has been of more interest to the study in order to evaluate properly the source of the problem.

  2. 2. Genome instability, gene expression and prognosis in breast cancer

    Author : Ulrike Kronenwett; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Breast adenocarcinoma; genomic instability; SSI; centrosomes;

    Abstract : Aneuploid cancers are regarded as being more malignant than tumors of other ploidy categories, and they are characterized by increased genomic instability. Our investigations resulted in the characterization of an aneuploid subtype of breast carcinoma that proved to be genomically stable. READ MORE

  3. 3. Exploring the complexities of integrating socioscientific issues in science teaching

    Author : Ulrika Bossér; Mats Lindahl; Mattias Lundin; Cedric Linder; Christina Ottander; Linnéuniversitetet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Scientific literacy; Socioscientific issues; Secondary school science; Teacher reflection; Classroom discourse; Science Education; Naturvetenskap med utbildningsvetenskaplig inriktning;

    Abstract : Socioscientific issues, SSI, can briefly be described as societal issues in which science plays a role. Dealing with SSI in science education is a means to prepare and empower students for active and responsible participation in a complex, democratic society. READ MORE

  4. 4. Dynamic soil-structure interaction of simply supported high-speed railway bridges

    Author : Johan Lind Östlund; Jean-Marc Battini; Andreas Andersson; Mahir Ülker-Kaustell; Rui Calçada; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic soil-structure interaction; Railway bridge; Impedance function; Soil dynamics; High-speed train; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Abstract : Research performed on the subject of dynamic soil-structure interaction (SS) concerning railway bridges is presented in this thesis with the focus on simply supported railway bridges supported by shallow foundations in soil strata on bedrock. The research aims to obtain insight into the SSI of high-speed railway bridges and to provide recommendations on how to model the soil-bridge system from a design perspective. READ MORE

  5. 5. Closure of midline abdominal incisions with small stitches : studies on wound complications and health economy

    Author : Daniel Millbourn; Leif Israelsson; Agneta Montgomery; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wound closure techniques; Postoperative complications; Surgical wound infection; Surgical wound dehiscence; Hernia; Costs; Cost analysis;

    Abstract : Background A midline incision inflicts minimal damage to muscles, nerves and blood supply. Postoperative complications cause patients suffering and costs for society. Midline incisions should be closed with a continuous single-layer technique and a suture length (SL) to wound length (WL) ratio over 4. READ MORE
