  1. 31. Wiring Components of the Respiratory Chain : Modulation of the Respiratory Chain in Yeast and Bacteria

    Författare :Jacob Schäfer; Peter Brzezinski; Dennis Winge; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cytochrome c oxidase; Electron transfer; Membrane protein; Ligand; Kinetics; Mechanism; Rcf1; Cytochrome c; Respiratory supercomplex; Cryo-electron microscopy; Biochemistry; biokemi;

    Sammanfattning : The enzyme complexes of the respiratory chain are organized in supramolecular assemblies, so-called respiratory supercomplexes. In the yeast Saccharomyces cerevisiae, these supercomplexes consist of two copies of complex III (bc1 complex) and one or two copies of complex IV (cytochrome c oxidase, CytcO). LÄS MER

  3. 32. Efficient mineral liberation – Multidimensional investigation of mechanical stress and ore texture

    Författare :Parisa Semsari Parapari; Jan Rosenkranz; Mehdi Parian; Hakan Benzer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Loading mechanism; Ore texture; Breakage mode; Fracture energy; Fragmentation; Breakage mechanism; Statistical analysis; 3D Deformation; Crack quantification; Mineral Processing; Mineralteknik;

    Sammanfattning : Within mineral comminution, the product properties (such as particle size distribution and mineral liberation characteristics) along with process efficiency are affected by material related and process environment factors. Understanding and optimizing these factors leads to designing and developing an energy-efficient process with a specified product. LÄS MER

  4. 33. Fluorescence Properties of Quantum Dots and Their Utilization in Bioimaging

    Författare :Hao Xu; Ying Fu; Hjalmar Brismar; Marina Zelenina; Mattias Goksör; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fluorescence; Microscopy; Bioimaging; Nanomaterial; cytotoxicity; mechanism; Biological Physics; Biologisk fysik;

    Sammanfattning : Quantum dots (QDs), especially colloidal semiconductor QDs, possess properties including high quantum yields, narrow fluorescence spectra, broad absorption and excellent photostability, making them extremely powerful in bioimaging. In this thesis, we studied the fluorescence properties of QDs and attempted multiple ways to boost applications of QDs in bioimaging field. LÄS MER

  5. 34. Model Systems for Metal - DNA Interactions. With a Focus on Anticancer Active Platinum(II) Complexes

    Författare :Anna Ericson; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kinetics; DNA; poly d T ; guanine; 6-thioinosine-5 -monophosphate; 6-thio-2 -deoxyinosine; 4-thiouridine-5 -monophosphate; 4-thio-2 -deoxyuridine; palladium II ; Gold III ; platinum II ; mechanism; salt effect; activation parameters; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Reactions of trans-dicyanodichloroaurate(III) trans-dibromodicyanoaurate(III), trans-diamminedichlorogold(III), cis-diammine(aqua)chloroplatinum(II), cis-ammineaqua-(cyclohexylamine)chloroplatinum(II), chloro(terpyridine)platinum(II) and chloro-(diethylenetriaminepalldium(II) with dimethyl sulfide, thionucleosides, thionucleotides and thione- and guanine-containing 17-mer oligonucleotides have been investigated by use of conventional and high-pressure stopped-flow spectrophotometry and HPLC technique as a function of ionic strength, pH, temperature and pressure in aqueous solutions. The mechanism and rate of oxidation of dimethyl sulfide by gold(III) complexes depends on the concentration of free halide. LÄS MER

  7. 35. Nakna män : Maskulinitet och kreativitet i svensk bildkultur 1900-1915

    Författare :Patrik Steorn; Margaretha Rossholm-Lagerlöf; Yvonne Eriksson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; image culture; visual culture; performativity; masculinity; male nude; queer studies; homosociality; vitalism; mechanism; physical culture; life-reform-movement; nationalism; artist’s role; Eugène Jansson 1862–1915 ; JAG Acke 1859–1924 ; Art; Konstvetenskap;

    Sammanfattning : At the turn of the 20th century, there was a notion in Europe that urbanisation and industrialisation had drained the human race of spiritual and physical energy. A particular concern was that men were being emasculated. LÄS MER
