In the transition zone between aquifers and basal aquitards, the perchloroethenepools are more recalcitrant than those elsewhere in the aquifer. The aim of this study is to demonstrate that the transition zone is an ecotone where the biodegradation of chloroethenes from aged-pools of perchloroethene is favored. A field site was selected where an aged pool exists at the bottom of a transition zo...

In information extraction from scientific texts, it is crucially important to identify the unique contribution of the research. The task is complicated by the large number of statements made in each article that pertain to results, including reference to previous work and technical details. Simple keyword searches are helpful for a content-based analysis but fail to tell new results from other ...

The Hawaiian hotspot is often attributed to hot material rising from depth in the mantle, but efforts to detect a thermal plume seismically have been inconclusive. To investigate pertinent thermal anomalies, we imaged with inverse scattering of SS waves the depths to seismic discontinuities below the Central Pacific, which we explain with olivine and garnet transitions in a pyrolitic mantle. Th...

This study presents the species richness, temporal distribution and reproductive activity of anurans from the Uaimií State Forest (Floresta Estadual do Uaimií - FLOE Uaimií), situated in the Quadrilátero Ferrífero region, municipality of Ouro Preto, Minas Gerais state, Brazil. Field activities were performed monthly from September 2009 to August 2010. We recorded 36 anurans species, distributed...

OBJECTIVES To develop and test a new video based method for match analysis that combines football specific and medical information to achieve a better understanding of the injury mechanisms and events leading up to high risk situations. METHODS Football incident analysis (FIA) is a video based method describing incidents that may result in an injury using 19 variables and categories modified ...
