Alluvial fans and fan-deltas are of three basic types: those built up primarily by the action of constantly avulsing river and stream channels, those constructed by sheet flows, and those resulting from. ~e successive deposition of debris flows. The present analysis is directed toward the first two types. A mechamstic formulation of flow and sediment transport through river channels is combined...

Most of our understanding of earthquake rupture comes from interpretation of strongground-motion seismograms; however, near-rupture-tip fields of stress and particle motions are difficult to resolve. In particular, the decay of frictional resistance from a peak value at the leading tip of the rupture to a residual kinetic value and subsequent healing characterizes the earthquake process, yet th...

To my family.. iii ACKNOWLEDGEMENTS There are many people whom I would like to acknowledge for their help and support as I made my way through this thesis work. Mike Schatz, my advisor, deserves much credit for the genesis of my research project. Mike's research model of each student being responsible for his or her experiment, the development of necessary computer programs, data acquisition an...

The Congenital Disorders of Glycosylation (CDG) are a clinically and genetically heterogeneous family of inherited diseases. Their clinical manifestations are truly multi-system. While the ophthalmological manifestations of CDG are not life threatening, they carry the potential for significant disease burden for the child and their family. In this brief review we highlight the ophthalmological ...

improve forage quantity and quality using organic and biological fertilizers production of important needs in dryland farming systems of the country. in this study the effects of foliar application of four different combinations of amino acid four different time steps were germinated plant growth, stem elongation, flowering and spraying all three steps above with the control treatment was carri...

The variance explained by the global fluctuations in resting state fMRI increases the correlation between functional systems, beyond the correlation that reflects their specific functional connectivity. Hence, removal of the global average (GA) signal facilitates the observation of specific physiological relationships among major functional systems (Fox et.al, 2009). However, removal of GA may ...

InAIAslInGaAs HFET’s fabricated by conventional mesa isolation have a potential parasitic gate-leakage path where the gate metallization overlaps the exposed channel edge at the mesa sidewall. We have unmistakably proven the existence of this path by fabricating special heterojunction diodes with different mesa-sidewall gate-metal overlap lengths. We find that sidewall leakage is a function of ...

Ready transformation and reactivity is observed at the nanoscale. Silica/silicon (SiOx) nanospheres of diameter %30 nm generated from equimolar Si/SiO2 mixtures are found to display enhanced catalytic and reactive properties relative to commonly employed silica support surfaces including fumed silica. A unique oxygen deficient synthesis has been used to generate SnO2Kx nanowires, nanoribbons, a...

Lipocortin-1 (annexin-1) is an endogenous peptide with antiinflammatory properties . We have previously demonstrated lipocortin immunoreactivity in certain glial cells and neurons in the rat brain (Strijbos, P. J . L . M., F. J. H . Tilders, F. Carey, R . Forder, and N. J . Rothwell . 1990 . Brain Res. In press .), and have shown that an NH2-terminal fragment (1-188) of lipocortin-1 inhibits th...
