2. 1. Serine Hydrolase Selectivity : Kinetics and applications in organic and analytical chemistry

   University dissertation from Stockholm : KTH

   Author : Anders Hamberg; KTH.; [2010]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Candida antarctica lipase B; monoacylation of diols; kinetic resolution; thermodynamics in enzyme catalysis; enzyme engineering;

   Abstract : The substrate selectivities for different serine hydrolases were utilized in various applications, presented in papers I-VI. The articles are discussed in the thesis in view of the kinetics of the enzyme catalysis involved. READ MORE

4. 2. EC State aid rules : An analysis of the selectivity criterion

   University dissertation from Uppsala : Juridiska institutionen

   Author : Mona Aldestam; Uppsala universitet.; [2005]
   Keywords : RÄTTSVETENSKAP JURIDIK; LAW JURISPRUDENCE; European law; EC State aid; Taxation; Derogation; Benchmark; Norm; Selectivity criterion; Justifications; Europarätt; Allmän rättslära; Jurisprudence;

   Abstract : The application of Art. 87(1) EC to taxes above all is connected to the application of the derogation method, which appears to be part of the selectivity criterion. This dissertation examines the application of the derogation method and the assessment of the selectivity criterion applied to taxes, primarily de lege lata, but also de lege ferenda. READ MORE

6. 4. Development and Application of Enzyme- and Antibody-based Assays with Emphasis on Selectivity, Sensitivity and Stability

   University dissertation from Catalin Nistor, Department of Analytical Chemistry, Lund University

   Author : Catalin Nistor; Lunds universitet.; Lund University.; [2002]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; sensitivity; stability; selectivity; cross-reactivity; sample matrix effects; environmental pollutants; enzyme biosensor; immunoassay; Analytical chemistry; Analytisk kemi;

   Abstract : This thesis presents the development, optimisation, and various applications of enzyme-based biosensors and immunoassays, mainly with relevance to environmental analysis. the thesis discusses problems and possible solutions associated with selectivity, sensitivity and robustness of such bioassays with emphasis on various immunoasssay configurations for determination of surfactants, phenols, or drugs, and amperometric biosensors based on enzymes (e.

7. 5. Exploring Selectivity and Hysteresis : Kinetic Studies on a Potato Epoxide Hydrolase

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Diana Lindberg; Uppsala universitet.; [2010]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Epoxide hydrolase; regioselectivity; selectivity; hysteresis; conformational changes; cooperativity; deep eutectic solvents; methylstyrene oxide; Biochemistry; Biokemi;

   Abstract : The kinetic mechanism of an α/β hydrolase fold epoxide hydrolase from potato, StEH1, has been studied with the aims of explaining the underlying causes for enantio- and regioselectivity, both being important for product purity. Further effort has been laid upon understanding the causes of a hysteretic behavior discovered in the measurements leading to Paper I. READ MORE
