  2. 1. Concerted or Stepwise? : β-Elimination, Nucleophilic Substitution, Copper Catalysed Aziridination and Ruthenium Catalysed Transfer Hydrogenation Studied by Kinetic Isotope Effects and Linear Free-Energy Relationships

    Author : Per Ryberg; Heinz F. Koch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Kinetic isotope effect; linear free energy relationship; elimination; substitution; aziridination; transfer hydrogenation; Organisk kemi; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis describes the use of kinetic isotope effects, linear free energy relationships and stereochamical studies to distinguish between different mechanistic alternatives and to obtain information about transition state structure.In the first part fluorine and deuterium kinetic isotope effects were determined for the base promoted HF elimination from 4-fluoro-4-(4’-nitrophenyl)butane-2-on.

  4. 2. Observability and identifiability of nonlinear systems with applications in biology

    Author : Milena Anguelova; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Observability; identifiability; nonlinear systems; time delay; delay systems; state elimination; metabolism; conservation laws; signalling pathways.; signalling pathways.;

    Abstract : This thesis concerns the properties of observability and identifiability of nonlinear systems. It consists of two parts, the first dealing with systems of ordinary differential equations and the second with delay-differential equations with discrete time delays. READ MORE

  6. 4. Aiming at malaria elimination in Zanzibar

    Author : Delér Shakely; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Following the increase of the international funding for implementation of the combined malaria control strategies in the past decade, a significant reduction of malaria attributed morbidity and mortality has been achieved. Yet, malaria is still a severe threat to global health. READ MORE

  7. 5. Towards elimination of airborne particles from rail traffic

    Author : Saeed Abbasi; Ulf Sellgren; Ulf Olofsson; Yannick Desplanques; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Airborne; brake block; brake pad; railway; subway; TEI; wheel–rail; wear; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Abstract : Since the investigation of wear particles from rail transport started in the late 1910s, the high mass concentrations of these particles have prompted concern among researchers interested in air quality. However, effective action has yet to be taken because relevant knowledge is still missing. READ MORE
