The potential water demand for fracturing fluids along with the possible flowback and produced water production is assessed for the Dutch Posidonia shale. Total water demand estimated for 25 years of ...
The surface characteristics of fractured specimens are important in hydraulic fracturing laboratory experiments. In this paper, we present a three-dimensional (3D) scanning device assembled to study t...
Since the early 1960s, an alternative wastewater discharge practice at The Pennsylvania State University has been researched and its impacts monitored. Rather than discharging treated wastewater to a ...
Shale gas extraction via horizontal drilling and hydraulic fracturing (HF) has enhanced gas production worldwide, which has altered global energy markets and reduced the prices of natural gas and oil....
This study examines methods to better predict improvement of a hidden disability of functional vision, spatial neglect, following stroke. Spatial neglect is a tendency to make visual judg...
The purpose of the study is to compare the efficacy of intra-articular hydraulic distension (IHD) for the treatment of painful stiff shoulders between capsule-rupturing and capsule-preserv...
This study is designed to see if doing regular training on a spatial imagery task leads to improvements in the ability to do the trained spatial imagery task and in the ability to get arou...
The goal of this study is to identify a non-invasive predictor or predictors that will increase the clinician's ability to identify patients with preterm labor (PTL) at risk for preterm de...

Methods used to take into account and incorporate spatial autocorrelation and regional variation into regression analysis models of data that has spatial dependency, and also to provide information on the spatial relationships among the variables.
A drilling technology in which NATURAL GAS is extracted from large deposits of impermeable rock formations known as shale, deep within the earth’s crust. This drilling technique involves injecting large volumes of high-pressure fracturing fluid (a mixture of water, sand, and chemicals) several thousand feet underground, thereby creating cracks or fissures in the shale formation, and releasing trapped gas.
Integration of spatial information perceived by visual and/or auditory CUES.
A process through which individuals encode information about their environmental CUES to facilitate SPATIAL NAVIGATION.
