High-volume horizontal hydraulic fracturing, a controversial new mining technique used to drill for shale gas, is being implemented worldwide. Chemicals used in the process are known neurotoxins, carcinogens, and endocrine disruptors. People who live near shale gas drilling sites report symptoms that they attribute to contaminated air and water. When they seek help from clinicians, a diagnosis ...

Recent physiological and psychophysical research has challenged the traditional view that motion and form information are processed in distinct, parallel pathways in the visual system. Rapid movement creates 'motion-streaks' parallel to the motion trajectory, which facilitate motion detection. Some motion-selective neurons in striate and extrastriate cortex are sensitive to motion parallel to t...

Ravigopal Vennelakanti Anshuman Sahu, Ph.D. Umeshwar Dayal, Ph.D. OVERVIEW: Disruptive innovation in an unconventional oil and gas industry such as the shale industry offers a promise to change the world’s economies. Advances in technologies such as horizontal directional drilling and hydraulic fracturing have fueled growth in the industry. However, oil and gas industry operators are facing tou...

Discrete wavelet transform is an effective tool to generate scalable stream, but it cannot efficiently represent edges which are not aligned in horizontal or vertical directions, while natural images often contain rich edges and textures of this kind. Hence, recently, intensive research has been focused particularly on the directional wavelets which can effectively represent directional attribu...

conjunction with horizontal drilling. However, the environmental implications of NG production and its use have been called into question.1-4 One of the major concerns is the amount methane (CH4) leakage from production activities and its impact on the life-cycle greenhouse gas (GHG) emissions of NG. Examining the Impacts of Methane Leakage on Life-Cycle Greenhouse Gas Emissions of Shale and Co...
