Investigation Of How Microbes Involved In Anerobic Digestion Of Vinasse Change As Functions Of Temperature, Vinasse Compositions And Time
(Environmental & Earth Science, 2014-09-17)Recent fossil fuel supply crunches and price spikes have prompted increased interest in ethanol as an alternative transportation fuel. However, vinasse, the liquid residue left from the distillation of ethanol, poses serious ... -
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 ... -
Liquid Flow and Gas Diffusion in Natural Rocks: Experimental and Simulation Studies
(2023-08-24)Natural rocks, as key components in energy and environmental geosciences, play crucial roles in groundwater extraction, geological storage of high-level nuclear waste, geothermal energy mining, and petroleum exploration ... -
Machine Learning-based Methods for the Segmentation of Scanning Electron Microscopy Images of Fine-Grained Shale Samples
(2022-12-15)The segmentation of scanning electron microscopy (SEM) images is critical yet time-consuming for geological studies, as it will need to differentiate the boundaries for different mineral objects to facilitate subsequent ... -
Modelling PM2.5 concentrations and spatial correlation with weather conditions and adult asthma in north Texas in 2014
(2020-05-29)The questions to be answered by this study are whether weather conditions correlate with PM2.5 concentrations, and whether there is a correlation between asthma-related hospital admissions and PM2.5 concentrations. The ... -
Motion And Rigidity Of The Caribbean Plate And Geodetic Observations Of Dominica, Lesser Antilles
The currently accepted kinematic model of the Caribbean plate presented by DeMets et al. (2007), is based on velocities from 6 continuous and 14 campaign GPS sites. This work attempts to refine the current plate model by ... -
MULTI-SCALE AND MULTI-APPROCH INVESTIGATIONS OF PETROPHYSICAL PROPERTIES AND FLUID FLOW IN NATURAL ROCKS
(2022-05-09)Natural rock is one of the most important geological attributes on the Earth that have been widely related to human daily life in various aspects. Rocks are usually utilized with respect to their petrophysical properties ... -
A Multiphysics Approach: Thermodynamics, Material Mechanics And Fluid Dynamics Of Magma Systems At Active Volcanic Regions
Understanding the genesis, incubation, evolution and equilibration of silicic magma reservoirs that drive and source volcanic activity all over the planet is fundamental to the discipline of geology. The subsurface processes ... -
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 ... -
On-road Measurement Of NOx And CO₂ Emissions From Biodiesel Produced From Different Feedstocks
(Environmental & Earth Science, 2012-07-25)Biodiesel has generated increased interest in the US and elsewhere recently as an alternative to petroleum-derived diesel. Because it can be produced from domestic feedstocks such as soybeans, canola oil, and even recycled ... -
Petrophysical Studies on Woodford Shale in Oklahoma and Wolfcamp Shale in Texas: A Multiple-Approach Methodology
(2022-05-09)The successful development of oil and gas from unconventional reservoirs in the United States proves the high petroleum potential that shale rock reserves. Petrophysical studies on shale rocks are an important part of ... -
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 ... -
Predicting Variability Of Basal Scour And Quantifying Vertical Connectivity For Channel-belt Reservoirs Using Observations From The Holocene Mississippi River And Channel-belt
Assessment of potential for draining unpenetrated but closely stacked channel-belt reservoirs from an existing belt penetration depends upon an understanding of the methods of and the likelihood for connectivity between ... -
