    Nyckelord :offshore deployments; risk assessment; wave energy converter installation; marine current energy converter installation; economic efficiency; time efficiency; offshore operations; point absorber; hydrodynamic analysis; slack sling criterion; hoisting system failure.;

    Sammanfattning : The depletion warning of non-renewable resources, such as gas, coal and oil, and the imminent effects of climate change turned the attention to clean and fossil fuel-free generated electricity. University research groups worldwide are studying solar, wind, geothermal, biomass and ocean energy harvesting. LÄS MER

  3. 17. Conformationally Constrained Nucleosides : Design, Synthesis, and Biochemical Evaluation of Modified Antisense Oligonucleotides

    Författare :Oommen P. Varghese; Lars Engman; Jacek Stawinski; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; chemically modified oligonucleotides; azetidine; aza-ENA-T; cyanomethylene locked; free energy of activation; diaxial interactions; chair conformation; stable duplex; human serum; snake venom phosphodiesterase; antisense agents; RNase H; Organisk kemi; Chemistry; Kemi;

    Sammanfattning : This thesis is concerned with synthesis, structure and biochemical analysis of chemically modified oligonucleotides with potential therapeutic applications. The three types of chemical modifications described here are: (a) A North-East locked 1',2'-azetidine nucleoside (b) A North locked 2',4'-cyanomethylene bridged nucleoside and (c) A 2',4'-aza-ENA-T nucleoside.

  4. 18. Computational prediction of receptor-ligand binding affinity in drug discovery

    Författare :John Marelius; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; computer-aided ligand design; molecular dynamics simulation; linear interaction energy; free energy perturbation; scoring function; dihydrofolate reductase; thrombin; serine proteases; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; Molecular Biotechnology; molekylär bioteknik avd f jonfysik ;

    Sammanfattning : The evaluation of inhibition constants or, more generally, receptor-ligand binding affinities is a crucial part of the drug discovery process. Chemical synthesis and affinity screening is only affordable for a limited number of compounds. This makes computational methods to predict binding affinities of candidate ligands highly desirable.

  5. 19. Isoconversional analysis for the prediction of mass-loss rates during pyrolysis of biomass

    Författare :Lina Norberg Samuelsson; Matthaus Babler; Rosana Moriana; Henrik Wiinikka; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pyrolysis; biomass; kinetics; cellulose; spruce; black-liquor; model-free; isoconversional; prediction; pyrolys; biomassa; kinetik; cellulosa; gran; svartlut; model-free; isoconversional; förutsägelse; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

    Sammanfattning : Biomass is the only renewable carbon source that can compete with fossil energy sources in terms of production of materials, chemicals and fuels. Biomass can be transformed into charcoal, liquid and gas through pyrolysis, i.e. pure thermal decomposition. LÄS MER

  7. 20. Techno-economic evaluation of integrated lignocellulosic ethanol production

    Författare :Elisabeth Joelsson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distillers dried grain with solubles; biorefinery; modelling; Aspen Plus; biogas; logging residues; spruce; wheat straw; wheat grain; heat; integration; pinch analysis; techno-economic evaluation; first generation; second generation; Ethanol; Lignocellulosic material;

    Sammanfattning : Sweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. LÄS MER
