Quantification of soil organic carbon using mid- and near- DRIFT spectroscopy
(Texas A&M University, 2004-09-30)New, rapid techniques to quantify the different pools of soil organic matter (SOM) are needed to improve our understanding of the dynamics and spatio-temporal variability of SOM in terrestrial ecosystems. In this study, ... -
Quantification of the Antimicrobial Substances Produced by Lactic Acid Bacteria used as an Intervention to Inhibit Escherichia coli O157:H7 and Salmonella in vitro and on Fresh Spinach (Spinacia oleracea)
(2012-02-14)The metabolic activity of bacterial microorganisms may influence the growth and metabolic activities of other microbes that are present in any specific niche. Lactic acid bacteria (LAB) are antagonistic to some microbial ... -
Quantification of Uncertainties Due to Opacities in a Laser-Driven Radiative-Shock Problem
(2013-03-28)This research presents new physics-based methods to estimate predictive uncertainty stemming from uncertainty in the material opacities in radiative transfer computations of key quantities of interest (QOIs). New methods ... -
Quantification of uncertainty during history matching
(Texas A&M University, 2004-09-30)This study proposes a new, easily applied method to quantify uncertainty in production forecasts based on reservoir simulation. The new method uses only observed data and mismatches between simulated values and observed ... -
Quantification of uncertainty in reservoir simulations influenced by varying input geological parameters, Maria Reservoir, CaHu Field
(Texas A&M University, 2005-02-17)Finding and developing oil and gas resources requires accurate geological information with which to formulate strategies for exploration and exploitation ventures. When data are scarce, statistical procedures are sometimes ... -
Quantifying Causes, Schedule, and Cost Impacts of Change Orders: "Is Alternative Contracting Really Effective?"
(2014-04-30)The most professions who are engaged in the highway construction industry would commonly concur with an idea that the project cannot be delivered with no change. Regardless of considering different contract methods or what ... -
Quantifying E. coli Discharge from Failing Onsite Sewage Facilities in the Dickinson Bayou Watershed, Texas
(2014-07-24)Since 1996, the E. coli levels in Dickinson Bayou have been considerably higher than the Texas state maximum of 126 colony forming units (CFU) per 100 mL for recreational waters. One hypothesis is that failing onsite sewage ... -
Quantifying land cover in a semi-arid region of Texas
(Texas A&M University, 2005-02-17)Changes with land cover and land use are closely integrated with water and other ecological processes at the land surface. Nowhere is that more apparent than in the Edwards Aquifer region of southcentral Texas. The Edwards ... -
Quantifying long term changes in streamflow characteristics in Texas
(Texas A&M University, 2005-02-17)Streamflow characteristics change over time as a result of water resources development and management projects, water use, watershed land use changes, and climate changes. The main objective of this thesis is to assess ... -
Quantifying non-axial deformations in rat myocardium
(Texas A&M University, 2005-02-17)While it is clear that myocardium responds to mechanical stimuli, it is unknown whether myocytes transduce stress or strain. It is also unknown whether myofibers maintain lateral connectivity or move freely over one another ... -
Quantifying Road User Costs with Heterogeneous Value of Motorists' Travel Time
(2013-08-01)The state transportation agencies (STAs) in the United States are mandated by federal rule to carry out work-zone impact assessment for highway rehabilitation projects. The work zone impact assessment requires calculating ... -
Quantifying the Benefit of Ensemble Selection for Optimization Under Uncertainty
(2014-08-07)Due to significant uncertainty in reservoir parameters, maximizing reservoir potential is an extremely difficult task. To be able to make decisions that maximize the reservoir potential, knowledge of possible ranges of ... -
Quantifying the Effect of Kerogen on Electrical Resistivity Measurements on Organic-rich Source Rocks
(2013-12-04)Interpretation of electrical resistivity logs in organic-rich source rocks has been challenging for petrophysicists. Conventional resistivity-porosity-saturation models (e.g., Archie?s, Dual-Water, and Waxman-Smits equations) ... -
Quantifying the Effectiveness of Innovative Contracting Strategies on Schedule, Cost and Change Order
(2013-08-01)The transportation infrastructure systems in the United States were built between the 50's and 80's, with 20 years design life. As most of them already exceeded their original life expectancy, State Transportation Agencies ... -
Quantifying the parameters of successful agricultural producers
(Texas A&M University, 2006-08-16)The primary purpose of the study was to quantify the parameters of successful agricultural producers. Through the use of the Financial and Risk Management (FARM) Assistance database, this study evaluated economic measures ... -
Quantifying the Permeability Heterogeneity of Sandstone Reservoirs in Boonsville Field, Texas by Integrating Core, Well Log and 3D Seismic Data
(2013-04-29)Increasing hydrocarbon reserves by finding new resources in frontier areas and improving recovery in the mature fields, to meet the high energy demands, is very challenging for the oil industry. Reservoir characterization ... -
Quantifying the strain response in the rat tibia during simulated resistance training used as a disuse countermeasure
(2009-05-15)Disuse of weight bearing bones has been shown to cause bone loss. This poses a health concern for people exposed to microgravity, such as astronauts. Animal studies are used to study factors related to bone loss and ... -
Quantifying the Uncertainty in Estimates of World Conventional Oil Resources
(2010-07-14)Since Hubbert proposed the "peak oil" concept to forecast ultimate recovery of crude oil for the U.S. and the world, there have been countless debates over the timing of peak world conventional oil production rate and ... -
