  1. 1. Rheology and Microstructure of Mixed Biopolymer Gels

    Författare :Leif Lundin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carrageenan; microstructure; rheology; xanthan; PCA; polysaccharide mixture; locust bean gum; transmission electron microscopy TEM ; multivariate analysis; viscoelastic measurements; PLS;

    Sammanfattning : The viscoelastic behaviour of biopolymer mixtures showing synergism was investigated under different physicochemical conditions using small deformation oscillatory measurements. In addition, the rheological properties of binary polysaccharide mixtures were related to the microstructure as observed using transmission electron microscopy. LÄS MER

  2. 2. Group B streptococcus capsular polysaccharide - Cholera toxin B subunit conjugate vaccine for mucosal immunisation : development and preclinical evaluation of experimental conjugate vaccines

    Författare :Xuzhuang Shen; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Group B streptococci (GBS) can colonize the female genital and rectal tracts and cause invasive infection in susceptible newborns. An optimally effective GBS vaccine should induce both mucosal and systemic immunity. LÄS MER

  3. 3. Structural studies of some bacterial polysaccharides and extension of a method for lipid A cleavage

    Författare :Reine Eserstam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Serratia marcescens; Hafnia alvei; Vibrio cholerae; polysaccharide; NMR;

    Sammanfattning : The focus of the work presented in this thesis has been to study the structures of the capsular polysaccharide from Serratia marcescens O14:K12, and the O-antigen polysaccharides from Hafnia alvei strain 10457 and Vibrio cholerae serogroup 037. Nuclear magnetic resonance (NMR) spectroscopy was the primary technique employed. S. LÄS MER

  4. 4. On the physico-chemical properties of softwood hemicellulose and compounds derived from it

    Författare :Polina Naidjonoka; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Hemicellulose is the second largest polysaccharide group available in nature after cellulose. Hemicellulose is present in plant cell walls along with cellulose and lignin. It is an abundant and biodegradable material that could potentially replace fossil-based products. LÄS MER

  5. 5. Application of Chemical Additives in Minerals Beneficiation – Implications on Grinding and Flotation Performance

    Författare :Vitalis Chipakwe; Saeed Chehreh Chelgani; Jan Rosenkranz; Tommy Karlkvist; Irina Chernyshova; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy; Grinding aid; Flowability; Dry grinding; FT4 Powder Rheometer; Surface properties; Rheology; Flotation; Polymers; Surface chemistry; Green Chemistry; Mineral Processing; Mineral Processing; Mineralteknik;

    Sammanfattning : The application of chemical additives, known as grinding aids (GAs), dates to 1930 in the cement industry. Unlike the cement industry, where the use of GAs is in the final processing step, it could be one of the first processing steps in ore beneficiation. LÄS MER
