  1. 1. Hydrophobic interactions of serpins

    University dissertation from Sabina Janciauskiene, Wallenberglab, University Hospital Malmö, S-20502 Malmö, Sweden

    Author : Sabina Janciauskiene; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Proteiner; enzymology; polymerization.; Proteins; conformational polymorphism; hydrophobic interaction; amyloid fibrils; Alzheimer`s peptide Ab; alpha-1-antichymotrypsin; C-terminal peptide; lithocholic acid; cholesterol; Key words: alpha-1-antitrypsin; bile acids; enzymologi;

    Abstract : The proteins of the serpin family are primarily but not exclusively proteinase inhibitors, which share a common, similar structure. It is known that this structure undergoes major conformational changes upon cleavage in the serpin reactive site loop, and that these changes include rearrangements within the hydrophobic core of the molecule.

  2. 2. Hydrophobic Impregnation of Concrete Structures Effects on Concrete Properties

    University dissertation from Stockholm : KTH

    Author : Anders Selander; Johan Silfwerbrand; Jan Trägårdh; Mårten Janz; Andreas Gerdes; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrophobic impregnation; silane; siloxane; concrete; surface treatment; water repellent agent; building protection; impregnering; betong; silan; siloxan; ytbehandling; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur;

    Abstract : Hydrophobic impregnations often referred to as water repellent agents, today mainly consisting of alkylalkoxysilanes, are often used on concrete to prolong the service life of the structure. This is accomplished by protecting the reinforcement bars from chlorides or by changing the moisture content inside. READ MORE

  3. 3. DNA strand exchange and hydrophobic interactions between biomolecules

    University dissertation from Stockholm : KTH

    Author : Bobo Feng; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATP synthase; DNA; membrane proteins; linear dichroism; Hydrophobic interactions; self-assembly; strand exchange; nanotechnology; liposomes;

    Abstract : The role of hydrophobic interactions in DNA strand exchange has been studied using fluorescence-labeled DNA oligomers in a FRET assay. Strand exchange was found to be accelerated in the presence of polyethylene glycol, which provides a crowded and hydrophobic environment possibly mimicking that of the catalytically active recombinase-DNA complexes.

  4. 4. Surface interactions and adsorbate structures : An atomic force microscopy study

    University dissertation from Stockholm : Kemi

    Author : Goran Bogdanovic; [2002]
    Keywords : atomic force microscope; AFM; cantilever calibration; colloidal probe; surface force; force curve; friciton; hydrophobic; adhesion; roughness; multilayer; silica; cellulose; cationic polyelectrolyte; MAPTAC;

    Abstract : Atomic force microscopy, AFM, was used for studying somecurrent topics in the field of surface and colloid science. Themain topics addressed in this thesis were: the nature of thelong-range attraction between hydrophobic surfaces; slidingfriction behavior for microscopic contacts; and interfacialstructuring of polyelectrolyte-nanoparticle multilayerfilms.

  5. 5. Chlorinated Paraffins: improved understanding of their bioaccumulation and toxicity in Daphnia magna

    University dissertation from Stockholm : Department of Environmental Science, Stockholm University

    Author : Mafalda Castro; Magnus Breitholtz; Anna Sobek; Elena Gorokhova; Lillemor Asplund; Martin Scheringer; [2020]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chlorinated paraffins; POPs; bioaccumulation; toxicity; ecotoxicology; aquatic toxicology; daphnia magna; liposomes; passive dosing; hydrophobic; mixtures; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Chlorinated paraffins (CPs) are industrial chemicals, mainly used as flame retardants, plasticizers and metal cutting fluids. Their production has reached historically high levels in the last decade, with an annual production exceeding one million tonnes. READ MORE
