  1. 31. Digital holography and image processing methods for applications in biophysics

    Författare :Hanqing Zhang; Magnus Andersson; Krister Wiklund; Wählby Carolina; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Digital holographic microscopy; image processing; image reconstruction; bacterial adhesion; cell morphology; algorithm development; software design; quantitative measurement; microfluidics; multidisciplinary research; signalbehandling; Signal Processing; teknisk fysik med inriktningen mikrosystemteknik; engineering science with specialization in microsystems technology;

    Sammanfattning : Understanding dynamic mechanisms, morphology and behavior of bacteria are important to develop new therapeutics to cure diseases. For example, bacterial adhesion mechanisms are prerequisites for initiation of infections and for several bacterial strains this adhesion process is mediated by adhesive surface organelles, also known as fimbriae.

  3. 32. CFD-based Analysis of Combustion Processes in a Free-Piston Diesel Engine

    Författare :Miriam Bergman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical kinetics; Diesel; homogeneous charge compression ignition HCCI ; free-piston; equivalence ratio vs. temperature maps; computational fluid dynamics CFD ; surrogate fuel;

    Sammanfattning : The Free Piston Engine (FPE) which is capable of operating in a variable compression ratio mode, allows flexible auto-ignition control on a cycle-to-cycle basis without any hardware modifications. In this study combustion processes in an FPE were examined using the KIVA-3V CFD code with detailed chemical kinetics (305 reactions among 70 species) of a Diesel surrogate fuel incorporated.

  4. 33. Protein folding, stability and recognition

    Författare :Jianxin Duan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Protein; folding; stability; recognition; molecular dynamics; protein-DNA interactions; simulation;

    Sammanfattning : Proteins make up for most of the dry mass of a cell and they are highly involved in virtually all cellular processes. The importance of the proteins is reflected by frequent association between dysfunctional proteins and diseases. Proteins have also wide applications in industries. LÄS MER

  5. 34. Chemical Methods for Improving the Fracture Toughness of Paper

    Författare :Andrew T. Horvath; Lars Wågberg; Theo van de Ven; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemistry; physical chemistry; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : Paper is a network material composed of a great number of fibers that interact with each other through fiber joints. In order to make a clear statement regarding observed changes being made in paper, it is vital to determine the structural level of paper that is being affected by chemical modifications. LÄS MER

  7. 35. Såsom en människa : Kristustolkningar i svensk 1900-talskonst

    Författare :Elisabeth Stengård; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Jesus; Bibliska motiv i konsten;

    Sammanfattning : The mass production of Christian art in the 19th century, including all the reproductions of the Christ by the Danish sculptor Bertel Thorvaldsen, has contributed to a cliché that many persons perceive as a true portrait of the historical Jesus, even though it ultimately stands, not for a historical probability, but for the classical ideal of noble beauty. The thesis takes up representations of Christ by a score of Swedish artists. LÄS MER
