Momentum and scalar transport in vegetated shear flows
(Massachusetts Institute of Technology, 2005)
Environmental aquatic flows are seldom free of vegetative influence. However, the impact of submerged vegetation on the hydrodynamics and mixing processes in aquatic flows remains poorly understood. In this thesis, I present ...
A continuum theory with long-range forces for solids
(Massachusetts Institute of Technology, 2005)
A non-local integral-type continuum theory, introduced by Silling [61] as peridynamic theory, is analyzed. The theory differs from classical (local) continuum theories in that it involves long-range forces that act between ...
Development of new parameters for structure determination and dynamic investigations on biomacromolecules by NMR
(Massachusetts Institute of Technology, 2005)
Nuclear magnetic resonance (NMR) spectroscopy is unique in the content of structural as well as dynamic information that it can provide at atomic resolution. The aim of this PhD-thesis was to contribute to the understanding ...
Mechanistic investigation of polyhydroxybutyrate (PHB) synthases and elucidation of PHB biosynthesis and degradation process in Wautersia eutropha H16
(Massachusetts Institute of Technology, 2005)
Polyhydroxyalkanoate (PHA) synthase from various bacterial organisms is able to catalyze the polymerization of (R)-hydroxyalkanoate-CoAs into high molecular weight PHAs under nutrient- limited conditions in the presence ...
Oligosaccharide-mediated targeting of dendritic cells and the development of carbohydrate microarrays
(Massachusetts Institute of Technology, 2005)
Bone-marrowed derived dendritic cells (DCs) constitute a critical arm of the immune system capable of polarizing the immune response toward active immunity or tolerance. Successful therapeutic modulation of DC function in ...
Critical thickness in silicone thermosets
(Massachusetts Institute of Technology, 2005)
Critical thickness effects are utilized to achieve high fracture toughness in brittle polymers. The postulate of critical thickness, which is: "Macroscopically brittle polymers deform in a ductile fashion below a critical ...
Two essays in commonality
(Massachusetts Institute of Technology, 2005)
In the first part of this thesis we consider a manufacturer that introduces successive generations of products, possibly on multiple similar production lines. We consider two types of production phase for this firm; pilot ...
Three-dimensional nanofabrication of photonic crystals and polarization splitters and rotators
(Massachusetts Institute of Technology, 2005)
One of the most critical challenges in nanoscale science and engineering is to make functional 3D nanodevices with high-accuracy. While considerable progress has been made in the "bottom-up" approach, the lithographic ...
Induced seismicity analysis for reservoir characterization at a petroleum field in Oman
(Massachusetts Institute of Technology, 2005)
This thesis presents the analysis and interpretation of passive seismic data collected in a 20-month monitoring period. The investigation is divided into four studies, each focusing on a different aspect of the seismic ...
Contraction and partial contraction : a study of synchronization in nonlinear networks
(Massachusetts Institute of Technology, 2005)
This thesis focuses on the study of collective dynamic behaviors, especially the spontaneous synchronization behavior, of nonlinear networked systems. We derives a body of new results, based on contraction and partial ...
