The spatial coherence structure of 30 infrasound array detections, with source-to-receiver ranges of 25–6500km, has been measured within the 0.25–1Hz passband. The data were recorded at International Monitoring System (IMS) microbarograph arrays with apertures of between 1 and 4 km. Such array detections are of interest for Comprehensive Nuclear-TestBan Treaty monitoring. The majority of ar…

Globalization has propelled a mass influx of trading, opportunities, wealth, and crossborder relations. But, it has also added distance to the seemingly endless gap between developed and developing nations. Amidst this economic disparity, trade preferences present a solution to alleviate developing country dissatisfaction by providing access to international markets. It finds legitimacy in the …

This article compares and reviews the panel and Appellate interpretations of the GATT Article III:8(a) procurement derogation in Canada � Renewable Energy. When this derogation is available, discriminatory domestic content requirements fall outside of the general GATT Article III:4 national treatment obligation, and are capable of challenge only under the more limited coverage of the plu…

While the first-order Born approximation is incre a singly being used in many seismic tomography efforts, its domain of validity to forward model seismic wave forms has not been quantified in the context of current 3-D earth models yet. We here address this issue by comparing teleseismic synthetic surface waveforms calculated using the Born approximation with spectral element method…

Surface nuclear magnetic resonance (surface-NMR) is a promising technique for exploring shallow subsurface aquifer structures. Surface-NMR can be applied in environments that are characterized as a 1-D layered Earth. The technique utilizes a single loop and is referred to as magnetic resonance sounding. The technique referred to as magnetic resonance tomography (MRT)allowscomplex2-D aquifer str…
