  2. 16. Tailoring adhesion and wetting properties of cellulose fibers and model surfaces

    Author : Emil Gustafsson; Lars Wågberg; Monika Österberg; Mikael Hedenqvist; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The layer-by-layer (LbL) technique was used to modify the surface of cellulose fibers by consecutive adsorption of poly(allylamine hydrochloride) (PAH) and poly(acrylic acid) (PAA) followed by a final adsorbed layer of anionic paraffin wax colloids. Paper hand sheets made from the modified fibers were found to be highly hydrophobic with a contact angle of 150°. READ MORE

  4. 17. Identification, Characterization and Evolution of Membrane-bound Proteins

    Author : Pär J. Höglund; Helgi B. Schiöth; Robert Fredriksson; Gert Vriend; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; G protein-coupled receptor; GPCR; Solute Carriers; SLC; Bioinformatics; Evolution; Rhodopsin; Adhesion; Phylogeny; Pharmacology; Farmakologi;

    Abstract : Membrane proteins constitute approximately 30% of all genes in the human genome and two large families of membrane proteins are G protein-coupled receptors (GPCRs) and Solute Carriers (SLCs) with about 800 and 380 human genes, respectively.In Papers I, II and IV, we report 16 novel human Adhesion GPCRs found by searches in NCBI and Celera databases.

  5. 18. The Enemy Below - Adhesion and Friction of Ship Hull Fouling

    Author : Dinis Oliveira; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship resistance; in-water hull cleaning; roughness; biofouling; hull grooming; frictional resistance; adhesion strength; turbulent boundary layer; hull form factor;

    Abstract : Below the waterline, commercial ships are good targets for marine organisms to attach and proliferate, a problem commonly known as biofouling. A fouled hull means higher hydrodynamic resistance, which can result in significant fuel penalties. READ MORE

  6. 19. Characterization and Evolution of Transmembrane Proteins with Focus on G-protein coupled receptors in Pre-vertebrate Species

    Author : Karl J. V. Nordström; Helgi B. Schiöth; Robert Fredriksson; Teresa Attwood; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; G protein-coupled receptors; GPCR; Membrane protein; Rhodopsin; Adhesion; Secretin; Evolution; Bioinformatics; Phylogeny; Pharmacological research; Farmakologisk forskning; Bioinformatics; Bioinformatik; Bioinformatik; Bioinformatics; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Abstract : G protein-coupled receptors (GPCRs) are one of the largest protein families in mammals. GPCRs are instrumental for hormonal and neurotransmitter signalling and are important in all major physiological systems of the body. READ MORE

  7. 20. Discrete element simulation of elasto-plastic shock waves in high-velocity compaction

    Author : Muhammad Shoaib; Leaf Kari; Bruska Azhdar; Wim Desmet; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-velocity compaction; Discrete element method; Plastic deformaiton; dynaimic loading; elasto-plastic shock wave; Friction; Adhesion; Physics; Fysik; Järnvägsgruppen - Ljud och vibrationer; Järnvägsgruppen - Ljud och vibrationer;

    Abstract : Elasto-plastic shock waves in high-velocity compaction of spherical metal particles are the focus of this thesis which consists of four papers (A-D). The compaction process is modeled by a discrete element method while using elastic and plastic loading, elastic unloading and adhesion at contacts. READ MORE
