  1. 6. Towards a mechanism for surface hydrophobization of paper - Effect of combinations of polyelectrolytes and polymer particles

    Författare :Frida Iselau; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; kinetics.; paper hydrophobization; starch; Surface sizing; interactions; aggregation;

    Sammanfattning : Paper materials are cost effective and light weighted, they can easily be recycled and their use as an alternative to plastics is advantageous from an environmental andsustainability perspective. However, competing with plastics for packaging applications is a challenge for cellulosic products. LÄS MER

  3. 7. On the two forms of amylose-lipid complexes

    Författare :Fredrik Tufvesson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bread; enzymatic hydrolysis; resistant starch; digestibility; fatty acid; monoglyceride; polar lipid; differential scanning calorimetry; annealing; amylose-lipid complex; crystallization; Food and drink technology; Livsmedelsteknik; Biotechnology; Bioteknik;

    Sammanfattning : This thesis is about the formation of amylose-lipid complexes, and their properties. Two forms of superstructures can be identified. Complex form I has more randomly distributed helices, while the structure of form II is crystalline and therefore exhibits the typical V-pattern in X-ray diffraction analyses. LÄS MER

  4. 8. Novel potato starch : new structure and beneficial qualities

    Författare :Xue Zhao; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis presents a simplified method for determining the internal molecular structure of whole starch without prior amylopectin isolation. The structure of potato and barley whole starches, the thermal properties of starch from potato lines with different genetic backgrounds and the relationship between molecular structure and functional properties of starch were examined in the thesis.

  5. 9. Characterization of Starch Using Flow Field-Flow Fractionation Techniques

    Författare :Catalina Fuentes; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : To improve the properties and functionality of starch, it is important to understand the physicochemical and structural characteristics as raw material, after being modified to increase its characteristics and/or during changes due to the processing conditions. For this reason, the objective of the present thesis is to improve the understanding of characteristics and molecular properties like molar mass (M), root-mean-square radius (rrms) and their relation to other physicochemical properties of starch extracted from different sources.

  7. 10. Species specific susceptibility testing for ß-lactam antibiotics. With special reference to staphylococci

    Författare :Ann Cathrine Petersson; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bakteriologi; mycology; Mikrobiologi; virology; bacteriology; beta-lactamase; staphylococcus; methicillin resistance; Microbiology; mecA susceptibility testing; virologi; mykologi;

    Sammanfattning : The main objective of this thesis was to identify methods for the detection of ß-lactam resistance in staphylococci, bacteria often causing nosocomial infections. Detection of ß-lactam resistance in these species is difficult due to strong regulation of genes encoding for the two main resistance mechanisms, ß-lactamase production and the penicillin-binding protein (PBP) 2?.
