  2. 11. Enzymes as catalysts in synthesis of enantiomerically pure building blocks : secondary alcohols bearing two vicinal stereocenters

    Author : Rong Liu; Hans-Erik Högberg; Torbjörn Norin; Thorleif Anthonsen; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enzyme; kinetic resolution; enantioselectivity; lipase; diastereoselectivity; epimerisation; metal-catalysed transformation; intramolecular alkylation.; Chemistry; Kemi;

    Abstract : Enzymes as tools in organic synthesis have provided enormous advantages. This thesis deals with the applications of enzymes in the kinetic resolutions of racemic compounds. The stereochemistry of chiral compounds and the kinetics of α/β hydrolase lipases are presented. READ MORE

  4. 12. Sparse Voxel DAGs

    Author : Viktor Kämpe; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geometry; Shadows; Data structures; Tree; Visibility; Grid; Voxel; Directed acyclic graph; Computer graphics;

    Abstract : This thesis investigates a memory-efficient representation of highly detailed geometry in 3D voxel grids. The memory consumption of a plain dense grid scales too fast as the resolution increases to be feasible at very high resolutions. READ MORE

  5. 13. Lefschetz Properties of Monomial Ideals

    Author : Nasrin Altafi; Mats Boij; Alicia Dickenstein; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Weak Lefschetz property; monomial ideals; group actions; almost linear resolution; Mathematics; Matematik;

    Abstract : This thesis concerns the study of the Lefschetz properties of artinian monomial algebras. An artinian algebra is said to satisfy the strong Lefschetz property if multiplication by all powers of a general linear form has maximal rank in every degree. If it holds for the first power it is said to have the weak Lefschetz property (WLP). READ MORE

  6. 14. Computerised Microtomography : Non-invasive imaging and analysis of biological samples, with special reference to monitoring development of osteoporosis in small animals

    Author : Mats Stenström; Gudrun Alm Carlsson; Carl Carlsson; Jim Elliot; Linköpings universitet; []
    Keywords : Computed microtomography; CμT; signal-to-noise ratio SNR ; non-invasive monitoring; morphological changes; Gastrectomized Sprague-Dawley; osteoporosis; MEDICINE; MEDICIN;

    Abstract : The use of Computerised microtomography (CμT) in biomedical research is well established, with most applications developed at synchrotron facilities. The possibility to non-invasively monitor morphological changes in biological samples, makes it an attractive technique in biomedicine. READ MORE

  7. 15. Considering intentions

    Author : Niclas Öhman; Handelshögskolan i Stockholm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : "Good resolutions are useless attempts to interfere with scientific laws. Their origin is pure vanity. Their result is absolutely nil". Oscar Wilde, The picture of Dorian Gray Different types of intentions are some of the most often used variables in marketing and consumer research. READ MORE
