  1. 16. Electrification in Process Industry - The Role of Process Integration and Future Energy Market Conditions

    Författare :Holger Wiertzema; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrification; bottom-up assessment; energy-intensive process industries; oxo synthesis; oil refining; energy market scenarios; techno-economic assessment; chemical industry;

    Sammanfattning : Electrification of industrial processes is a frequently discussed strategy to reduce greenhouse gas emissions from energy-intensive process industries and is highlighted in many roadmap studies. Electricity is a versatile energy carrier that enables a broad variety of options in which existing process unit operations are replaced with electricity-driven alternatives. LÄS MER

  3. 17. Environmental Assessment and Strategic Technology Choice : The Case of Renewable Transport Fuels

    Författare :Karl Hillman; Björn Sandén; Ken Green; Göteborg Chalmers Tekniska Högskola Miljösystemanalys Institutionen för energi och miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental assessment; life cycle assessment LCA ; socio-technical change; strategic technology choice; renewable fuels;

    Sammanfattning : The scale of the required changes is huge, and time is limited if we are to avoid the most severe effects of climate change. To reduce greenhouse gas emissions from road transport, several fuels and electricity originating from renewable energy sources have been proposed, all of them in different stages of development and with various and shifting environmental impacts.

  4. 18. Reliability-based assessment procedures for existing concrete structures

    Författare :Joakim Jeppsson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; reliability theory; service life; assessment; monitoring; hydraulic engineering; Civil engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Sammanfattning : A feasibility study of reliability theory as a tool for the assessment of present safety and residual service life of damaged concrete structures has been performed in order to find a transparent methodology for the assessment procedure. It is concluded that the current guidelines are open to interpretation and that the variation in the results obtained regarding the structural safety is too great to be acceptable. LÄS MER

  5. 19. The sensational hand. Clinical assessment after nerve repair

    Författare :Birgitta Rosén; Malmö Handkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; substitution of senses; artificial sensibility; reliability; validity; diagnose-specific; documentation; assessment; longitudinal; functional outcome; hand; sensibility; ulnar nerve; nerve repair; median nerve; brain plasticity; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Following the transection and repair of major nerve trunks in the forearm, the functional outcome is influenced by mechanisms in the peripheral, as well as in the central nervous system. In the present thesis the interest is focused on assessment of the outcome after nerve repair, central nervous factors influencing the outcome, and sense substitution to compensate for sensory loss.

  7. 20. Det kontrollera(n)de klassrummet : bedömningsprocessen i svensk grundskolepraktik i relation till införandet av nationella skolreformer

    Författare :Tord Göran Olovsson; Jörgen From; Agneta Hult; Christian Lundahl; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; assessment process; classroom practice; school reforms; classification; framing;

    Sammanfattning : The aim of this thesis is to investigate the assessment process in Swedish compulsory school practice, and the changes that occur in relation to the introduction of national school reforms. The fieldwork forming the basis of the thesis was conducted in year five and year six classrooms between 2011-2013, a period during which new national syllabuses with knowledge requirements, grades in year six and extended national tests were introduced.
