  1. 1. The measurement of chemical persistence in the field by benchmarking Theory and Experiment

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Författare :Hongyan Zou; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chemical benchmarking; persistence; half-lives; modeling; threshold benchmarking; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Persistence is one of the core criteria in chemical exposure and hazard assessment. It is often defined as the half-life for the removal of a chemical from a specified environment by transformation. Chemicals with long transformation half-lives may pose high risks for wildlife or humans and be subject to long-range transport to remote areas. LÄS MER

  2. 2. The measurement of chemical persistence in lakes using benchmarking techniques

    Detta är en avhandling från Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Författare :HONGYAN ZOU; Stockholms universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; benchmarking; persistence; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The persistence of a chemical that indicates resistance to degradation is one of the core criteria for exposure and hazard assessment of chemicals. However, it is rarely measured in the real environment because of the lack of appropriate methods. LÄS MER

  3. 3. Benchmarking e-learning in higher education:Lessons learned from international projects

    Detta är en avhandling från Juvenes Print

    Författare :Ebba Ossiannilsson; [2012]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; benchlearning; benchmark; benchmarking; e-learning open learning; quality; quality assurance; quality enhancement; success factors;

    Sammanfattning : Higher education is facing a range of major challenges during the twenty-first century. Personalised, flexible and open learning are considered among the driving forces, thus, issues of quality must be urgently addressed. LÄS MER

  4. 4. Benchmarking Points-to Analysis

    Detta är en avhandling från Linnaeus University Press

    Författare :Tobias Gutzmann; Linnéuniversitetet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Points-to Analysis; Dataflow Analysis; Static Analysis; Dynamic Analysis; Gold Standard; Software Technology; Programvaruteknik;

    Sammanfattning : Points-to analysis is a static program analysis that, simply put, computes which objects created at certain points of a given program might show up at which other points of the same program. In particular, it computes possible targets of a call and possible objects referenced by a field. LÄS MER

  5. 5. Energy performance of multifamily buildings building characteristic and user influence

    Detta är en avhandling från Umeå : Print och media

    Författare :Jan-Ulric Sjögren; Umeå universitet.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy performance; total heat loss coefficient; gain factor; benchmarking; parameter influence; multivariate method; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik;

    Sammanfattning : Today many professional property holders use different types of software for monthly energy analyses. The data is however often limited to energy and water use, that is paid for by the property holder. In year 2001, financed by the Swedish Energy Agency, the first steps were taken to create a national web based data base, eNyckeln. LÄS MER
