  1. 1. Aging and heat-sealing properties of films based on wheat gluten

    Författare :Sung-Woo Cho; Mikael Hedenqvist; Minna Hakkarainen; Mikael Lindström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheat gluten; aging; migration; opacity; heat sealability; shear strength; Polymer chemistry; Polymerkemi;

    Sammanfattning : Recently the research interest of the possibility of using wheat gluten (WG) as packaging material has greatly increased due to its combination of high gas barrier, attractive mechanical, film-forming and renewable properties. The source is also readily available and inexpensive on a worldwide basis. LÄS MER

  3. 2. Functional characterization of the alternative reading frame protein p14ARF

    Författare :Mikael Lindström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :p14ARF; p19ARF; alternative reading frame; CDKN2A; p53; B23; nucleophosmin; Burkitt´s lymphoma; nucleolus; senescence; Myc; E2F; phosphorylation; RNA interference; ribosome biogenesis;

    Sammanfattning : A deeper understanding of the molecular events underlying tumor development is a prerequisite for the design of novel and efficient therapies. Inactivation of the p53 and retinoblastoma (Rb) tumor suppressor pathways appears as a common theme in most malignant human tumors. LÄS MER

  4. 3. Injector Nozzle Hole Parameters and their Influence on Real DI Diesel Performance

    Författare :Mikael Lindström; Hans- Erik Ångström; Öivind Andersson; KTH; []
    Nyckelord :Mechanical engineering; Maskinteknik;

    Sammanfattning : A modern diesel engine is capable of running efficiently with low exhaust gas emissions over a wide operating range. This is thanks to techniques such as turbocharging, EGR, charge air cooling and an advanced fuel injection process. The fuel injection process is important for the combustion and emission formation in the diesel engine. LÄS MER

  5. 4. Some factors affecting the amount of residual phase lignin during kraft pulping

    Författare :Mikael E. Lindström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deligniflcation; Residual phase lignin; Hydrogensulfide ion; Hydroxide ion; Polysulfides; Ionic strength; Temperature; Lignin; Kraftpulping; Selectivity; viscosity; Kappa number; chemical degradation; Disproportionation; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : The amount of lignin which needs to be removed according to the slow residual delignification phase in kraft pulping, i e residual phase lignin, has been studied as a function of the process conditions. The variebles studied were the concentrations of hydroxide ions, hydrogensulfide ions, sodium ions (ionic strength) and temperature. LÄS MER

  7. 5. Methods for Characterization of the Diesel Combustion and Emission Formation Processes

    Författare :Mikael Lindström; Hans-Erik Ångström; Werner Hentschel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diesel engine emissions; SRA - Energy; SRA - Energi;

    Sammanfattning : In this thesis various aspects of the diesel engine fuel injection, combustion and emission formation processes have been evaluated. Several types of evaluation tools and methods have been applied. Fuel spray momentum was used to characterize injection rate and hole-to-hole variations in fuel injectors. LÄS MER
