Energy Absorption Capacity of Graphite-Epoxy Composite Tubes
… tow (towpreg) from Thiokol, were Akzo Fortafil 50k fiber and aerospace-grade T300 12k fiber. Using the towpreg, sixteen tubes were filament wound on aluminum mandrels. Three specimens were cut from each of these tubes for a total of forty-eight specimens. Twenty-four of these specimens were …

Microstructure Evolution of Two Model Ferritic/Martensitic Steels Under Ion Irradiation In A Transmission Electron Microscope
… alloys were irradiated with 1 MeV Kr ions at 50K, 180K, 298K, 473K and 673K to doses up to 10 dpa in-situ in a TEM. The microstructure evolution under irradiation was followed and characterized at successive doses in terms of irradiation-induced defect formation and evolution, black dot …

NMR as a probe for molecular adsorption on metal surfaces in electrochemical environments and at electrified interfaces
… for $\sp{15}$N: over the temperature range from 50K to 200K, T$\sb1\cdot$T is $\sim$ 4300 s$\cdot$K, much larger than that of $\sp{13}$C; but at above 200K, T$\sb1\cdot$T is $\sim$ 3000 s$\cdot$K, indicating a small structural rearrangement. The above T$\sb1\cdot$T results show that the …

Characterizing A Novel Genetic Locus Associated With Familial Co-Occurrence of Thoracic Aortic Aneurysms and Intracranial Aneurysms
… on nine members of this family using the 50k GenChips Hind array from Affymetrix. This analysis eventually identified a single disease-segregating locus, on chromosome 5p15. We build upon this previous analysis in this study, hypothesizing that a genetic mutation inherited in this locus …

A GIS-Based Comparative Study of Superfund Contaminants and the Threat They Represent to Eastern Harris County Communities
… level education, and 38% earning less than $50K annually. These demographic statistics suggest possible communication barriers for the population to respond adequately to a potential health threat. In particular, 17 cancer clusters, which include incidences of brain, melanoma, breast, …

Quantum wells on indium gallium arsenic compositionally graded buffers realized by molecular beam epitaxy
… was a significant PL decay mechanism between 50K to about 250K for the aluminum containing unannealed quantum well samples. For the unstrained ones, this mechanism could be removed effectively by annealing. However, strain in quantum well was observed to retard this removal. The same …

Abnormalities affecting tyrosine kinase signalling in atypical myeloproliferative disorders
… I have undertaken a screen using Affymetrix 50K SNP arrays for regions of acquired isodisomy as a means to identify genomic regions that may harbour novel oncogenes in different subgroups of MPD patients. Large tracts of homozygosity (defined as >20Mb running to a telomere), strongly …

Functional Block Copolymers via Anionic Polymerization for Electroactive Membranes
… piperidine) diblock and a 50K poly(tert-butyl styrene-co-isoprene-co-4-vinylbenzyl piperidine) triblock. Alkylation studies involving a phosphonium bromide salt demonstrated the future avenues for piperidinium based polymer designs. These investigations introduce piperidinyl …

Three-dimensional structure of a type III glutamine synthetase by single particle reconstruction
… in E.coli YMC11 (glnA-), were recorded at 50K magnification using a Leo 912 operating at 120kV with energy filtering coupled to a 4 megapixel CCD camera. An angular refinement based reconstruction strategy was adopted using SPIDER. A reconstruction based on an ab initio starting model, …

The structure of the nitrilase from Rhodococcus Rhodochrous J1: homology modeling and three-dimensional reconstruction
… using a JEOL 1200EXII operating at 120 kV at 50K magnification. Two independent 3D reconstructions were generated using the IHRSR algorithm executed in SPIDER. These converged to the same structure and the resolution using the FSC 0.5 criterion was 1.7 nm. The helix structure has a diameter of …

High temperature spectroscopic measurements of aluminum combustion in a heterogeneous shock tube
… This optical access allowed high speed images (50k fps) of the particle motion, ignition, and combustion. Results are presented which give a more complete understanding of burntime variability in the heterogeneous shock tube, owing to the contribution of initially wall-bound particles vs. those …
