  1. 1. Human copper ion transfer : from metal chaperone to target transporter domain

    Författare :Moritz Sebastian Niemiec; Pernilla Wittung-Stafshede; Nigel Robinson; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; copper homeostasis; copper chaperone; Atox1; ATP7B; Wilson disease protein; metal transport; size exclusion chromatography; thermodynamics; isothermal calorimetry;

    Sammanfattning : Many processes in living systems occur through transient interactions among proteins. Those interactions are often weak and are driven by small changes in free energy. LÄS MER

  2. 2. New insights into lubricated tribological contacts

    Författare :Elin Larsson; Staffan Jacobson; Åsa Kassman Rudolphi; Jannica Heinrichs; Philip Shipway; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; friction; wear; lubrication; fuel additive; boric acid; tribofilm; transport; fuel efficiency; surface analysis; grease; LiX grease; PP grease; fretting; electrical contacts; cross section; copper; silver; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : The emissions of carbon dioxide, CO2, must rapidly be reduced to avoid severe climate change. Tribology-related solutions can be an important part in reducing these emissions. The aim of this thesis is to improve the fundamental knowledge in two tribology-related fields, both concerning lubrication, to enable such solutions in the future. LÄS MER

    Nyckelord :NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; luminal loop; metal binding domains; Wilson’s disease protein; yeast model; ATP7B; copper transport.;

    Sammanfattning : ABSTRACT Copper (Cu) is an important trace element that plays a vital role in several biological processes. It mediates numerous biochemical functions to maintain cellular homeostasis making it an essential metal for sustaining life. LÄS MER

  4. 4. The use of fluorescence techniques for the study of some membrane-bound photosynthetic properties and some effects of copper on the thylakoid membrane

    Författare :Göran Samuelsson; N. Valanne; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; chlorophylI-protein complexes; sequential extraction; ß-carotene low temperature fluorescence emission; absorption; in vivo chi. a fluorescence; copper; electron transport;

    Sammanfattning : Lyophilized pea chloroplasts were extracted in a stepwise manner in an organic solvent (petroleum ether) with increasing polarity which was obtained by addition of small amount of ETOH (0-1 %). Absorption and low temperature fluorescence emission spectra were measured on both the extracted thylakoids and on isolated chlorophylI-protein complexes. LÄS MER

  5. 5. Transport of Heavy Metals in Soil Subjected to an Electric Field -A Study of the Transport of Copper in Bentonite Clay

    Författare :Klas Arnerdal; KTH; []
    Nyckelord :Electrokinetic soil remediation; bentonite; copper; adsorption; electromigration; electroosmosis; pH; potential;

    Sammanfattning : This licentiate thesis addressesphosphorus release from sewage sludge, which is the first stepin phosphorus recovery. The concept ofphosphorus recovery maybe seen as a part of sustainable sludge handling in that it isa means of recycling resources without supplying harmfulsubstances to humans or the environment.
