  1. 1. Hydrophobicity Patterns in Protein Folding

    Författare :Frank Potthast; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; global optimization; multisequence; Fourier analysis; hydrophobicity; protein folding; simulated tempering; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; kvantmekanik; klassisk mekanik; gravitation; relativitet; termodynamik; statistisk fysik; alpha-helix; protein design.; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; relativity; Fysicumarkivet A:1998:Potthast;

    Sammanfattning : The protein folding problem is addressed focussing on the hydro- phobicity patterns in the amino acid sequences and structures. Both real and model proteins are investigated. The hydrophobicity pattern of real proteins is probed in two ways. First, it is asked which binary pattern is most conserved within groups of related proteins. LÄS MER

  2. 2. Estimation of hydrophobicity of insulating surfaces by studying sessile water drops

    Författare :Marcus Berg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; hydrophobicity; contact angle; insulator; water; silicone; image processing; image analysis; Young-Laplace equation; droplet; axisymmetric; Materialvetenskap; Materials science; Teknisk materialvetenskap; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

    Sammanfattning : Today, the traditional insulator materials for high voltage powerlines, i.e. glass and porcelain, are gradually being replaced with new materials, most notably silicone rubber. LÄS MER

  3. 3. Betulin-modified cellulosic textile fibers with improved water repellency, hydrophobicity and antibacterial properties

    Författare :Tianxiao Huang; Monica Ek; Mats Johansson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antibacterial; Betulin; Biorefinery; Cellulose; Grafting; Coating; Hydrophobicity; Textile; Water repellency; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Textiles made from natural sources, such as cotton and flax, have advantages over those made of synthetic fibers in terms of sustainability. Unlike major synthetic fibers that have a negative impact on the environment due to poor biodegradability, cotton cellulose is a renewable material. LÄS MER

  4. 4. HYDROPHOBIC PEPTIDE TAGS - As tools in bioseparation and investigation of recombinant proteins

    Författare :Sara Fexby; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; E. coli; Biochemical technology; Biokemisk teknik; fusion protein; tyrosine; hydrophobicity; Hydrophobic interaction chromatography; aqueous two-phase system;

    Sammanfattning : This thesis describes the possibility of using hydrophobic peptide tags as tools for bioseparation and for the investigation of recombinant proteins. The hydrophobicity of a protein can easily be changed by minor modifications, such as fusions of tyrosine-containing peptides. LÄS MER

  5. 5. Thermodynamics of Protein Folding and Design

    Författare :Erik Sandelin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein folding; hydrophobicity; Monte Carlo; sequence analysis; sequence assembly; shotgun sequencing; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity; gravitation; statistical physics; Matematisk och allmän teoretisk fysik; thermodynamics; termodynamik; Fysicumarkivet A:2000:Sandelin; statistisk fysik; relativitet; protein design; klassisk mekanik; kvantmekanik;

    Sammanfattning : The protein folding and protein design problems are addressed, using coarse-grained models with only two types of amino acids, hydrophobic and hydrophilic. In addition to hydrophobicity forces, the models contain sequence-independent local interactions which are found to strongly influence the thermodynamics of these models. LÄS MER
