1. 1. Pyrolysis profiles and global kinetics of tropical biomass : coconut and cashew nut shells

   Författare :Alberto Júlio Tsamba; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermogravimetry; cashew nut cocnut shells; pyrolysis; kinetics; Other materials science; Övrig teknisk materialvetenskap;

   Sammanfattning : Biomass has been recognised as renewable and environmentally friendly source of energy since decades. Tropical biomasses which are available in large quantities as residues in Latin America, Africa and Asia, have high energy potential for exploitation through thermochemical conversion process, as pyrolysis, gasification or combustion.

3. 2. Development of an efficient solver for detailed kinetics in reactive flows

   Författare :Andrea Matrisciano; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Tabulated chemistry; Detailed chemistry; Stochastic Reactor Model; Progress Variable; Chemical lumping;

   Sammanfattning : The use of chemical kinetic mechanisms in CAE tools for reactive flow simulations is of high importance for studying and predicting pollutant formation. However, usage of complex reaction schemes is accompanied by high computational cost in both 1D and 3-D CFD frameworks. LÄS MER

4. 3. Accelerator-driven systems : safety and kinetics

   Författare :Marcus Eriksson; Janne Wallenius; Hamid Aït Abderrrahim; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Nuclear physics; Kärnfysik;

   Sammanfattning : The accelerator-driven system (ADS) is recognized as a promising system for the purpose of nuclear waste transmutation and minimization of spent fuel radiotoxicity. The primary cause for this derives from its accelerator-driven, sub-critical operating state, which introduces beneficial safety-related features allowing for application of cores employing fuel systems containing pure transuranics or minor actinides, thereby offering increased incineration rate of waste products and minimal deployment of advanced (and expensive) partitioning and transmutation technologies.

5. 4. Studies of the anomeric center : mechanism and synthesis

   Författare :Karl-Jonas Johansson; Harri Lönnberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

   Sammanfattning : This thesis is based on three publications and one appendix and is divided into two parts. The first part is a mechanistic study of the anomerization reaction of both aldo and keto glycosides and the second part is a synthetic study of a unusual type of glycosidic linker found in the lipopolysaccharide core Proteus Mirabilis 0270.

7. 5. 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
