In conjunction with ongoing studies to develop a method for quantifying potentially biodegradable organic carbon (Rectanus et al 2005), this research was conducted to evaluate the extent to which organic carbon extracted using this method will biodegrade in anaerobic environments. The ultimate goal is to use this method for the evaluation of chloroethene contaminated sites in order to estimate the long-term sustainability of monitored natural attenuation (MNA) as a remediation strategy. Although relatively recalcitrant under aerobic conditions, the breakdown of chlorinated solvents primarily occurs through the anaerobic process of reductive dechlorination. The biodegradation of organic carbon in these anaerobic environments drives the system to reducing conditions conducive for reductive dechlorination. The extraction procedure developed by Rectanus et al. (2005) has been tested in several series of aerobic bioassays to determine the biodegradable fraction of carbon extracted. This study seeks to show that the carbon removed from the sediment by this extraction process will also degrade in anaerobic environments. Three aquifer sediment samples characterized by low, medium, and high carbon concentrations were taken from Naval Submarine Base Kings Bay, Georgia. Two sites were also sampled from Naval Amphibious Base Little Creek, Virginia. MLS20 is a site located inside of a chloroethene plume, and MLS10 is located outside of the plume. For approximately 12 weeks aqueous total organic carbon (TOC), headspace carbon dioxide (CO2), volatile fatty acids (VFAs), and headspace hydrogen concentrations were monitored for evidence of the biodegradation of organic carbon. Although few VFAs were observed throughout the experiments, their presence as early as 8 days after inoculation indicated that the bioassays were anaerobic. The fewest VFAs were seen in the MLS20 bioassays, while the most VFAs were observed in the MLS10 bioassays. MLS20 exhibited low levels of TOC loss and the low VFA levels indicate that complex organic matter was not highly degraded in these bioassays. The higher level of VFAs observed in MLS10 bioassays corresponded with little TOC degradation, indicating that although more complex organics were being broken down, conditions were not reduced enough to further oxidize the organic carbon. As much as 50% TOC loss was observed in the Kings Bay bioassays with few VFAs detected. Loss of TOC was accompanied by CO₂ generation which provides supporting evidence that organic carbon was being oxidized. Hydrogen was observed in the bioassays, suggesting that VFAs resulting from organic carbon breakdown were being oxidized. This indicates that organic carbon removed from sediment using the extraction process is biodegraded anaerobically and could lead to conditions capable of sustaining reductive dechlorination. / Master of Science

The upper layer sediments were collected from eight ports (22 sampling points) of Kaohsiung and Pingtung in southwest Taiwan. The organotin contents in sediment are all related to the grain size. The concentration of tributyltin (TBT) is between 0.041~4.843 ppm (as Sn) , the concentration of dibutyltin (DBT) is between 0.001~4.626 ppm (as Sn), and the concentration of monobutyltin (MBT) is between 0.001~4.908 ppm (as Sn). The Chien-chen harbor presents the hightest butyltins concentrations, and the TBT contents is much over 10-d LC50 to bivalve (2.6 ppm) and amphipoda (2.1 ppm). The concentrations of triphenyltin (TPT), diphenyltin (DPT) and monophenyltin (MPT) are between ND~0.298 ppm (as Sn), ND~0.216 ppm (as Sn) and ND~0.143 ppm (as Sn) individually. The highest phenyltin concentrations are shown in the outfall of Love River (the inflow of Love River in Kaohsiung Port). The organic carbon and nitrogen contents show significant the positive correlation (R2=0.757), and the organotin concentrations also show a positive correlation with the contents organic carbon.All the butyltins show a positive correlation with the quantities of boats. According to this study, the port of Kaohsiung presents the most serious content of butyltins and phenyltins in sediment. All the other ports also present a TBT content higher than 0.24 ppm. Therefore, it is recommended to monitor the organotin contents in the ports of this studying area.

Abstract The primary objective of this study was to determine the isotopic variation of the sedimentary organic carbon (£_13Corg) in the sediment samples of the gravity core 17950-2. The core was retrieved from the northern South China Sea during ¡§Monitoring Monsoon¡¨ cruise onboard R/V Sonne in 1994. The £_13Corg data were further compared with other proxies, such as foraminiferal £_18O and £_13C, TOC wt%, and CaCO3 wt% to decipher the late Quaternary evolution of climate change from the South China Sea for the last 200 ky. Prior to 65 ka, the £_13Corg, calibrated TOC wt% (TOC ex wt%), and Terrestrial wt% fluctuated synchronously. The increased TOC ex wt% and Terrestrial wt% were consistent with the enriched £_13Corg, implying the enhanced productivity due to the increased terrestrial input. The enhanced glacial productivity could have been caused by the increase in terrestrial input and mixed layer by wind-driven upwelling. The South China Sea, however, is a nitrogen-limited basin. The enhanced nitrogen fixation induced by increased dust input can also be a potential candidate that is responsible for the elevated productivity during glacials. Theoretically, the £_13Corg is utilized as a powerful tool to determine the carbon ratio between marine and terrestrial origin in the shelf area and reconstruct the pCO2 history of the low-productivity open ocean. According to TOC ex wt%, the productivity of the northern South China Sea were significantly higher in glacials than interglacials. Therefore, the variation of pCO2 of the northern South China Sea can not be reconstructed properly based on £_13Corg record solely .

Identification of favorable production zones in hydrocarbon-bearing shale often requires the quantification of in-situ mechanical properties. These properties are also necessary for the optimal design of hydro-fracturing operations. Rock elastic properties are affected by volumetric concentrations of mineral constituents, porosity, fluid saturations, and total organic carbon (TOC). Rapid depth variations of rock properties often encountered in shale gas formations make conventional petrophysical interpretation methods inadequate to estimate volumetric concentration of mineral constituents. We introduce a new method to assess elastic properties of organic shale based on the combined quantitative interpretation of sonic, nuclear, and resistivity logs. In-situ elastic properties of organic shale are estimated by (a) improving the assessment of volumetric concentrations of mineral constituents, (b) implementing reliable rock physics models and mixing laws for organic shale, and (c) numerically reproducing wideband frequency dispersions of Stoneley and flexural waves. An example of the application of the method is described in the Haynesville shale gas formation. Estimates of mineral concentrations, porosity, and fluid saturations are in agreement with available laboratory core measurements and X-Ray Diffraction (XRD) data. Calculated layer-by-layer P- and S-wave velocities differ by less than 15% from measured velocities thus confirming the reliability of the method. Finally, based on the new interpretation method developed in this thesis, correlations are found between mineral concentrations, TOC, porosity, and rock elastic properties, which can be used in the selection of optimal production zones. / text

In this study, a tool is developed for determining priorities of quality improvement activities for manufacturing operations, for the purposes of both quality and throughput improvement. This tool utilizes Quality Function Deployment (QFD), Theory of Constraints (TOC), Statistical Process Control (SPC) and Failure Mode and Effects Analysis (FMEA) methodologies. The use of the tool is demonstrated on an example problem. The results obtained under different experimental conditions are compared with solutions of more popular, simple decision-making measures, and the optimal solutions obtained from a mathematical model. The analysis shows that the proposed tool gives close solutions to optimal, and it can easily be applied in a typical manufacturing setting. This study also demonstrates how various different methodologies can be integrated for the purposes of quality and throughput improvement in shorter times.
