EBSD data for sheared partially molten rocks (olivine + basalt)
No full textThe samples included in this data set are 0609, 0705, 0765, 0767, 0775, 0817.
Files are .ctf files exported from the HKL channel5 software. Basic noise reduction has been done as described in the paper.
Each file is named by the sample number and the section of the map.This data set contains the EBSD data for samples of olivine + basaltic melt deformed in torsion. The results are published in "Crystallographic preferred orientation of olivine in sheared partially molten rocks: The source of the 'a-c switch'" by Chao Qi, Lars Hansen, David Wallis, Ben Holtzman and David Kohlstedt on Geochemistry, Geophysics, Geosystems (G-cubed) 2018.NSF OCE-1459717NSF EAR-1520647NERC NE/M000966/1Qi, Chao; Kohlstedt, David L.

Optical micrographs of olivine + melt samples deformed in torsion
No full textAn excel spreadsheet summarizes the experimental conditions of the samples included in this data set, and also includes figures that plot the azimuthally averaged, normalized melt fraction vs. the radius for the starting material and each experimental condition.
For each sample (with the exception of experiment PT0767), the following data are included.
1. Tiles of 8-bit gray-scale optical microscopic images of 1000x1000 pixels. 1 pixel = 0.32 micron. There is ~20% overlapping between each tile.
2. A txt file registering the relative coordinates of each tile.
3. A black and white image with melt being white processed from the tiles and assembled by their coordinates. 1 pixel = 0.32 micron.
4. A mosaic microscopic image with lower resolution. In the file name, "OL" stands for optical light. 1 pixel = 1.3 micron.
For experiment PT0767, no high resolution images were obtained for this sample. For experiment PT0817, two files with relative coordinates exist, with one overlapping row that can be used to stitch the two halves together.This data set contains high-resolution micrographs of the transverse sections of partially molten samples deformed in torsion. These micrographs present the distribution of melt induced by deformation, which is a test of the melt segregation processes predicted by the two-phase flow theory incorporating viscous anisotropy.NSFQi, Chao; Kohlstedt, David L.

The L-Proline-Catalyzed Asymmetric Syntheses
No full textIn recent years, L-proline has been employed as the catalyst for the intra-and intermolecular aldol reactions, α- amination of aldehydes and ketones, and three-component Mannich reactions. These proline-catalyzed asymmetric reactions showed high stereoselectivities and gave products with high ee values some time up to > 99%. Examples are given to illustrate the versatility of L-proline in chiral organic syntheses
Vulnerability and Resilience of the Bang Luang Community to Flooding from the Chao Phraya River
No full textFlooding is a natural phenomenon and in the past Thai people have adapted to flood events. However over the years land degradation, deforestation and bad urban practices have exacerbated the impact of flood disasters. This study of flood management in Thailand shows how human activities and interventions have impacted on the river basin system. This research focuses on the vulnerability to flood hazard of the people living or working near the Chao Phraya River. The case study is of the community living or working in the proximity of Wat Bang Luang (Bang Luang Temple) of the Pathum Thani Province, Thailand.
This research explores the capacity of communities to live with or cope with floods. Their adaptations to changes in flood regimes will depend on several factors: political (especially when Thailand has a long history of preoccupation with engineering and technological solutions as the main approach to disaster response), economic, ecological (human modification to flood plains), social (kin-based networks) and cultural factors.
The data collected from the target community showed a power struggle between Thai culture and the dominant hazard management paradigm. This research put a human face on natural disaster and looked at the issue of flooding from the experiences of ordinary people. The findings showed that some members of the community are resilient while others are passive and are more vulnerable to floods. However, it is important not to label any individual or group as either vulnerable or resilient as people can be both at the same time and policy makers need to build on the strengths, rather than focus on the weaknesses and on offering emergency relief
