  2. 6. Applications of hydrodynamic forces for membrane chromatography

    Author : Björn Johansson Fast; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane chromatography; FRAP; Protein accumulation; Supported lipid bilayer; Microfluidics; SEEC; Diffusion; Hydrodynamic forces; Label-free;

    Abstract : Membrane proteins are proteins that reside in the cell membrane. Due to their position in the cell membrane, the barrier between the cell interior and exterior, they are vital to cell signaling. Moreover, the presence of membrane proteins in the cell's signaling pathways make membrane proteins important drug targets. READ MORE

  4. 7. Spin-dependant transport in lateral nano-devices based on magnetic tunnel junctions

    Author : Mattias Urech; Vladislav Korenivski; Bernard Dieny; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spin diffusion; magnetic tunnel junctions; Physics; Fysik;

    Abstract : This thesis is an experimental study of spin dependent transport in nanoscale ferromagnetic tunnel junction arrays and lateral multi-terminal devices with normal metal and superconducting spin transport channels. Two-, three-, and five-junction arrays have been fabricated in the form of lateral circuits and characterized using variable temperature magneto-transport measurements. READ MORE

  5. 8. Diffusion Tensor Imaging and Tractography in Epilepsy Surgery Candidates

    Author : Daniel Nilsson; Göteborgs universitet; []
    Keywords : epilepsy; epilepsy surgery; temporal lobe resection; optic radiation; diffusion tensor imaging; tractography;

    Abstract : In selected patients with medically refractory epilepsy, surgical treatment can render the patients seizure free or significantly reduce seizure frequency. Temporal lobe resection (TLR) for temporal lobe epilepsy (TLE) is the most commonly performed epilepsy surgery procedure. READ MORE

  6. 9. Magnetic resonance imaging and diffusion tensor imaging after brachial plexus injury and repair : Experimental and clinical study

    Author : Grainne Bourke; Mikael Wiberg; Lev N. Novikov; Lars Dahlin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brachial Plexus; Magnetic Resonance Imaging; Neonatal; Diffusion Tensor Imaging;

    Abstract : Brachial plexus injuries (BPI) cause permanent upper limb paralysis and serious disability in adults and children. Timely identification of the severity of nerve injury and early appreciation of the inane potential for recovery would revolutionise management. READ MORE

  7. 10. NMR Diffusion Studies in Heterogeneous Systems. Surfactant solutions, Polymer solutions and Gels

    Author : Magnus Nydén; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; pfg nmr; polydispersity ehec ddas; polymer surfactant self-diffusion self-association heterogeneous media; Fysikalisk kemi;

    Abstract : The aim of this study has been to investigate the self-diffusion behaviour in polymer solutions and in surfactant solutions using the pulsed field gradient (PFG) NMR technique. The NMR self-diffusion experiment was shown to provide detailed information in complex surfactant mixtures. READ MORE
