  1. 21. C2- and C3-symmetric ligands via ring-opening of aziridines

    Författare :Fredrik Lake; KTH; []
    Nyckelord :asymmetric catalysis; aziridine; benzaldehyde; diethylzinc; enantionselective; ligand; proazaphosphatrane; ring-opening; sulfonamide; symmetry; titanium; nicronium;

    Sammanfattning : This thesis deals with the design and synthesis of chiralenantiopure nitrogencontaining ligands and the use of theseligands in asymmetric catalysis. A modular synthetic approachto enantiopure nitrogen-containing ligands was developed. Thesynthetic method is based on the ring-opening of activatedchiral aziridines by nitrogen nucleophiles. LÄS MER

  2. 22. Protein modularity : Structure and interactions by NMR and SPR

    Författare :Amélie Wallenhammar; Maria Sunnerhagen; Björn Wallner; Lotta Tollstoy-Tegler; Helena Berglund; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Protein degradation is a fundamental cornerstone of regulation of protein levels in the human body. For proper function, numerous molecular processes rely on fine-tuned communication through specific interactions between proteins. LÄS MER

  3. 23. YopD translocator function in Yersinia pseudotuberculosis type III secretion

    Författare :Tiago R. D. Costa; Matthew S. Francis; William D. Picking; Umeå universitet; []
    Nyckelord :Y. pseudotuberculosis; T3SS; translocon; YopD; coiled-coil; effector delivery; regulation; virulence; mikrobiologi; Microbiology;

    Sammanfattning : Type III secretion systems (T3SS) are a common feature of Gram-negative bacteria, allowing them to inject anti-host effectors into the interior of infected eukaryotic cells. By this mechanism, these virulence factors help the bacteria to modulate eukaryotic cell function in its favor and subvert host innate immunity. LÄS MER

  4. 24. On Reference Architectures for Development of Flexible Cell Control Systems

    Författare :Per Gullander; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shop-floor control; generic modelling; cell control; flexible manufacturing systems; modelling framework; reference architecture; computer-integrated manufacturing;

    Sammanfattning : Industrial problems of inflexible and expensive shop-floor control systems were analysed. The principal causes are suggested to be poor development methodology, poor tools used for development and implementation, and poor knowledge on how such systems are best built. LÄS MER

  5. 25. Towards 3D Covalent Organic Framework Films

    Författare :Martin Ratsch; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; COF; PAF; framework material; 3D; continuous flow; QCM; flims;

    Sammanfattning : Porous materials are of great scientific interest because they are able to interact with guests, such as ions, atoms and molecules throughout their entire volume. One big subgroup of organic porous materials are covalent organic frameworks (COFs), which are mainly synthesized as powders with an uncontrolled grain size. LÄS MER
