Trace Element Geochemistry In Groundwater Flow Systems
(Environmental & Earth Science, 2011-03-03)
This research focuses on trace element geochemistry in three groundwater flow systems: the Carrizo Sand, the Upper Floridan, and the Aquia aquifers. The focus is threefold: (i) studying the geochemical behavior, concentrations, ...
Numerical Simulation Of The Base-level Buffers And Buttresses Conceptual Model Of Fluvial Systems
(Geology, 2012-07-25)
A Buffer in fluvial stratigraphy is a potentiometric surface which defines either: a) the lowest possible depth to which streams will incise; or b) the maximum elevation to which aggradation will occur; together, these ...
Bismuth-based Oxide Semiconductors: Mild Synthesis And Practical Applications
(Environmental & Earth Science, 2012-04-11)
In this dissertation study, bismuth based oxide semiconductors were prepared using 'mild' synthesis techniques - electrodepostion and solution combustion synthesis. Potential environmental remediation and solar energy ...
Predicting The Geographic Distribution Of Ancient Soils With Special Reference To The Cretaceous
(Environmental & Earth Science, 2012-04-11)
Different kinds of soils form in different climatic regimes. Soils closely match climatic conditions. Therefore, they are one of the best indicators of past climates. This study uses the "climate envelope" technique developed ...
Air Emissions From Natural Gas Exploration And Mining In The Barnett Shale Geologic Reservoir
(Environmental & Earth Science, 2011-10-11)
This study evaluates air emissions from natural gas mining and production in the Barnett Shale within the Dallas/Fort Worth Metroplex. Due to advances in horizontal drilling and hydraulic fracturing, natural gas production ...
Proximity Of Cancer Cases To Airports Within The State Of Texas
(Environmental & Earth Science, 2012-07-25)
Determining whether the incidence of cancer may be associated with pollutants emitted from airports is important in order to better plan cities to reduce such incidences. This research aims to answer the following questions: ...
Sensitivity of the Younger Dryas climate to changes in freshwater, orbital, and greenhouse gas forcing in comprehensive climate models
(2016-05-11)
The Younger Dryas cooling event (~12,900 years before present) was the most recent abrupt climate change in the geologic record where climate for the Northern Hemisphere returned to a near-glacial state. The cause of this ...
A MODERN RESERVOIR ANALOG FOR A POORLY DRAINED “HIGH ACCOMMODATION” FLUVIAL SYSTEM: SEDIMENTARY PROCESSES, ARCHITECTURE, AND RESERVOIR CONNECTIVITY OF THE GRIJALVA SYSTEM, TABASCO STATE, MEXICO
(2016-09-12)
High-accommodation fluvial systems are subject to much modeling and substantial rock drilling and imagination, but limited modern field observation. The Grijalva River system of Tabasco State, Mexico offers the opportunity ...
Identifying Source of Lead Particles in Floor Dust Using Computer Controlled Scanning Electron Microscope (CCSEM)
(2016-05-10)
Identifying the sources of lead (Pb) in indoor dust by analysis of the contents of the dust provides an opportunity to mitigate the source of contamination. In this study, it is hypothesized that in residential properties ...
Investigation of petrophysical properties and fluid migration in unconventional oil/gas reservoirs
(2019-05-07)
Petrophysics deals with the physical and chemical properties of petroleum-bearing rocks and their interactions with associated fluids. The investigation of petrophysical properties of interest, such as porosity, specific ...
