  1. 6. NMR structral studies on ruthenium complexes binding to DNA

    Author : Lisha Wu; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; DNA binding; Ru-complex dimer; CD; fluorescence; molecular dynamics simulation;

    Abstract : The Ru-complex Λ,Λ-[bidppz(bipy)4Ru2]4+ (Λ,Λ-B) exhibits multiple modes of interactions with the palindromic DNA dodecamer [d(CGCGAATTCGCG)]2, however excluding any type of intercalation as shown by both optical spectroscopy and NMR. NMR observation of Λ,Λ-B titration into a DNA solution results in both a transient binding, with observation of fast exchange for protons located near the ends of the DNA duplex, and a more stable interaction in the DNA minor groove indicated by a slow exchange mechanism and binding sites for G2, G4 and A5 of the same DNA strand.

  2. 7. Lipoprotein lipase mechanism for adaptation of activity to the nutritional state

    University dissertation from Umeå : Umeå university

    Author : Gengshu Wu; Umeå universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; adipose tissue; heparin; extracellular; nutrition; turnover; actinomycin; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; Biochemistry; biokemi;

    Abstract : Lipoprotein lipase (LPL) is an enzyme to hydrolyze triglycerides in lipoproteins and thereby make the fatty acids available for cellular metabolic reactions. Short-term fasting down-regulates LPL activity in adipose tissue. This regulation is through post-translational mechanism. READ MORE

  3. 8. Unveiling biomacromolecule interactions-NMR and optical spectroscopy studies on ligand binding to DNA and lysozyme

    University dissertation from Umeå : Umeå university

    Author : Lisha Wu; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ruthenium compounds; intercalation; Hoechst 33258; CD; fluorescence; DNA; structure rearrangements.; lysozyme; NMR;

    Abstract : Studies on intercalation of bulky binuclear ruthenium compounds into DNA have attracted attention due to their slow dissociation rate and sequence selectivity. Previous results showed that dumb-bell shaped molecules of the type [μ-(bidppz)(L)4Ru2]4+, L=phenanthroline or bipyridine, bind rapidly on the surface of DNA prior to intercalation. READ MORE

  4. 9. Computational Fluid Dynamics Modeling of Biomass Gasification in Fixed-bed Reactors Using Highly Preheated Agent

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Yueshi Wu; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass; high temperature agent gasification; CFD modeling; exergy efficiency; Energiteknik; Energy Technology;

    Abstract : Biomass gasification is considered to be one of the most promising energy recovery technologies for the widespread utilization of biomass. Mathematical models have been developed to understand the gasification process inside gasifiers. READ MORE

  5. 10. Modeling of the wet-out process in composites manufacturing

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Da Wu; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process modeling; liquid composite molding; fiber preform deformation; free surface flow; porous media theory;

    Abstract : The fiber reinforced polymer composites (FRPCs) are carving out a niche amid the keen market competition to replace the other material counterparts, e.g., metals. Due to the low weight and corrosion resistance, the FRPCs are wildly utilized from aviation to automobile industries; both in the sectors of civilian and defense. READ MORE
