  1. 1. Studies of protein structure, dynamics and protein-ligand interactions using NMR spectroscopy

    Författare :Tobias Tengel; Göran Larsson; Maria Sunnerhagen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 19F NMR; 2S albumin; PapD; protein-ligand interaction; structure; TFE; Yersinia; YopD; allergy; amphipathic helix; Ber e 1; Brazil nut; dynamics; FimC; LcrH; NMR screening; Biophysics; Biofysik;

    Sammanfattning : In the first part of the thesis, protein-ligand interactions were investigated using the chaperone LcrH, from Yersinia as target protein. The structure of a peptide encompassing the amphipathic domain (residue 278-300) of the protein YopD from Yersinia was determined by NMR in 40% TFE. LÄS MER

  3. 2. Water and protein solutions studied by field-dependent magnetic relaxation

    Författare :Kristofer Modig; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; relaxation; protein solvation; protein dynamics; protein denaturation; oxytocin; magnetic relaxation dispersion; nuclear magnetic resonance; lipid-binding protein; hydration; beta-lactoglobulin; BPTI; shielding anisotropy; water; Molecular biophysics; Molekylär biofysik;

    Sammanfattning : In the work presented, nuclear magnetic resonance (NMR) relaxation is used to study wide range of systems. The thesis concerns solvent interactions studied with relaxation techniques that involve measurements at many fields, which allows the separation of individual relaxation mechanisms. LÄS MER

  4. 3. Development and Applications of Hypervalent Iodine Compounds : Powerful Arylation and Oxidation Reagents

    Författare :Nazli Jalalian; Berit Olofsson; Viktor V. Zhdankin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hypervalent iodine compounds; diaryliodonium salts; oxidation; Koser s reagent; arylation; phenols; diaryl ethers; chemoselectivity; organisk kemi; Organic Chemistry;

    Sammanfattning : The first part of this thesis describes the efficient synthesis of several hypervalent iodine(III) compounds. Electron-rich diaryliodonium salts have been synthesized in a one-pot procedure, employing mCPBA as the oxidant. Both symmetric and unsymmetric diaryliodonium tosylates can be isolated in high yields. LÄS MER

  5. 4. Creating new experience for zoo visitors by using media techniques

    Författare :Karin Fahlquist; Thomas Mejtoft; Haibo Li; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociala medier; elektroniska tjänster;

    Sammanfattning : In 2008, the EU project “Digital Djurpark” (Digital Zoo) started as a cooperation between the digital media lab at the department of Applied Physics and Electronics (TFE) at Umeå University and Lycksele Zoo. The technology behind the Digital Zoo project is a wireless sensor network that is placed in the park. LÄS MER
