  1. 1. Development of connections for fibre reinforced bridge elements and an analysis of sustainability

    Author : Valbona Mara; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge; insert; connection; deck; FRP; bolt; joint; fibre reinforced polymer; LCC; LCA;

    Abstract : The deterioration of existing bridge structures due to a number of causes has led researchersto pursue new construction materials with high performance, such as fibre reinforced polymer(FRP) composite materials. The inherent properties of FRP materials are their light weight,high strength and high resistance to aggressive environments. READ MORE

  2. 2. Fibre reinforced polymer bridge decks: Sustainability and a novel panel-level connection

    Author : Valbona Mara; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge; Sustainability; LCA; Life-cycle assessment; FRP deck; LCC; Life-cycle cost; Connection;

    Abstract : Fibre reinforced polymer (FRP) bridge decks have emerged as a competitive alternative to traditional decking solutions for the refurbishment of existing bridges, as well as the construction of new ones, in the past two decades. FRP decks offer inherent properties such as light weight, high strength and high resistance to aggressive environments. READ MORE

  3. 3. Support and Resistance Ambivalence in Special Education

    University dissertation from Stockholm : HLS Förlag

    Author : Mara Westling Allodi; Stockholms universitet.; [2002]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; children; comprehensive school; disability; psychosocial environment; self-concept; special education; SOCIAL SCIENCES Social sciences Education; SAMHÄLLSVETENSKAP Socialvetenskap Pedagogik; pedagogik; Education; specialpedagogik; Special Education;

    Abstract : Support and Resistance discusses the interaction between pupils of different abilities and the school organisation. The dissertation has its point of departure in the views of pupils, both those with special support and their classmates. It outlines how school is – and how it should be – in the views of schoolchildren. READ MORE

  4. 4. Constraints on up-regulation of drug efflux in the evolution of ciprofloxacin resistance

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lisa Praski Alzrigat; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ciprofloxacin; antibiotic resistance; drug efflux; bacterial fitness; marR; acrR; marA; experimental evolution; Mikrobiologi; Microbiology;

    Abstract : The crucial role of antibiotics in modern medicine, in curing infections and enabling advanced medical procedures, is being threatened by the increasing frequency of resistant bacteria. Better understanding of the forces selecting resistance mutations could help develop strategies to optimize the use of antibiotics and slow the spread of resistance. READ MORE

  5. 5. Assessing the toxic impact of chemicals using bacteria

    University dissertation from Stockholm : Karolinska Institutet, Microbiology and Tumor Biology Center (MTC)

    Author : Jenny Gabrielson; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacteria; toxicity testing; ecotoxicity; phylogenetic diversity; growth inhibition;

    Abstract : There is a considerable backlog in the testing of new chemical compounds for their ecotoxic properties, mostly due to the lack of appropriate testing methods. In addition, there is a vivid debate today about the test endpoint for many of the existing methods. READ MORE
