Synaptic Vesicles Studied by Small-Angle X-Ray Scattering / Synaptische Vesikel untersucht mittels Kleinwinkel-Röntgenstreuung

Castorph, Simon Johannes 14 June 2010 (has links)
Die heterogene Struktur von aus Rattenhirn isolierten Synaptischen Vesikeln wird untersucht mittels Daten aus Kleinwinkel-Röntgenstreuexperimenten unter Berücksichtigung von Daten erhalten durch cryogene Elektronenmikroskopie, dynamische Lichtstreuung und biochemische Analysen. Es werden niedrig aufgelöste Strukturmodelle des funktionellen Synaptischen Vesikels unter quasi-physiologischen Bedingungen vorgeschlagen. Details des Dichteprofils der Membran, einschließlich Beiträgen von Lipiden und Proteinen werden bestimmt. Die typische Konformation und die allgemeine laterale Organisation der Proteine in Mikrodomänen werden ermittelt. Entropische Beiträge zur freien Energie aufgrund möglicher Bildung und Auflösung der Proteinmikrodomänen auf dem Synaptischen Vesikel werden untersucht. Ferner werden zellfreie Fusionssysteme mittels dynamischer Lichtstreudaten charakterisiert und mögliche Anwendungen von Kleinwinkel-Röntgenstreuung für die Untersuchung von Membran-Fusionsprozessen erörtert.

Development of a Slab-on-Girder Wood-concrete Composite Highway Bridge

Lehan, Andrew Robert 23 July 2012 (has links)
This thesis examines the development of a superstructure for a slab-on-girder wood-concrete composite highway bridge. Wood-concrete composite bridges have existed since the 1930's. Historically, they have been limited to spans of less than 10 m. Renewed research interest over the past two decades has shown great potential for longer span capabilities. Through composite action and suitable detailing, improvements in strength, stiffness, and durability can be achieved versus conventional wood bridges. The bridge makes use of a slender ultra-high performance fibre-reinforced concrete (UHPFRC) deck made partially-composite in longitudinal bending with glued-laminated wood girders. Longitudinal external unbonded post-tensioning is utilized to increase span capabilities. Prefabrication using double-T modules minimizes the need for cast-in-place concrete on-site. Durability is realized through the highly impermeable deck slab that protects the girders from moisture. Results show that the system can span up to 30 m while achieving span-to-depth ratios equivalent or better than competing slab-on-girder bridges.
