  1. 16. A comparative cost analysis of conventional wrought steel and powder metallurgy (PM) gear manufacturing technologies

    Författare :Babak Kianian; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gear manufacturing; Manufacturing cost analysis; Powder metallurgy PM ; Press and sintering P S ; Wrought steel conventional gear manufacturing; Decision support system DSS ; Sustainability; Sustainable production SP ; Automotive Industry;

    Sammanfattning : The transportation industry landscape is going through a massive transformation due to trends such as autonomous and electrified vehicles. The electrification trend has already started to display its ample influence on the automotive industry. LÄS MER

  3. 17. Parameters in wet grinding : the influence of process variables on autogenous and conventional grinding

    Författare :Hongxin Zhai; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : The effects of autogenous and conventional grinding on the liberation of particles have been studied on the laboratory, pilot and industrial scales. It appears that autogenous grinding, down to flotation fineness, results in a higher degree of liberation and smoother particle surface for flotation, than is obtained with conventional grinding.

  4. 18. CYTOGENETIC AND MOLECULAR GENETIC CHARACTERIZATION OF LIPOMAS

    Författare :Hammurabi Bartuma; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; soft tissue tumors; adipocytic tumors; conventional lipomas; spindle cell lipoma; HMGA2; cytogenetic; molecular genetic; SNP array; GGE;

    Sammanfattning : The focus of this thesis was to study cytogenetic and molecular genetic aberrations in lipomas. For this purpose, chromosome banding analysis, fluorescence in situ hybridization (FISH), as well as high resolution single nucleotide polymorphism (SNP)–arrays were used to identify recurrent chromosomal aberrations in lipomas.

  5. 19. World oil supply in the 21st century : A bottom-up perspective

    Författare :Henrik Wachtmeister; Mikael Höök; Jamie Speirs; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oil supply; oil production; oil prices; bottom-up; projections; conventional oil; tight oil; shale oil; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Sammanfattning : Oil-fuelled progress was a defining feature of the 20th century, and still today, oil remains the world’s largest primary energy source. Yet, oil is a non-renewable and carbon-intensive resource, either depletion or resulting carbon emissions will ultimately limit its use. LÄS MER

  7. 20. Problem-based and conventional medical education from a student perspective : a qualitative analysis comparing students' experience of medical education, approach to learning and reading comprehension

    Författare :Ameneh Rahimi; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Problem-Based Learning PBL ; medical education; learning approach; learning outcome; attitudes; experimental design; qualitative analysis.;

    Sammanfattning : The study is primarily an empirical investigation to students' experiences of university education, approaches to learning and comprehension of a learning task. Sixty medical students, equally distributed over a PBL and a traditional medical school have participated in this study. LÄS MER
