[1] The middle of a hillslope hollow in the Oregon Coast Range failed and mobilized as a debris flow during heavy rainfall in November 1996. Automated pressure transducers recorded high spatial variability of pore water pressure within the area that mobilized as a debris flow, which initiated where local upward flow from bedrock developed into overlying colluvium. Postfailure observations of th...

We present an analysis of the optical data of the Hubble Deep Field South. We derive F300WAB, F450WAB, F606WAB and F814WAB number counts for galaxies in our catalogue (Volonteri et al. 2000): the number-counts relation has an increasing slope up to the limits of the survey in all four bands. The slope is steeper at shortest wavelengths: we estimated γF300WAB ∼ 0.47± 0.05, γF450WAB ∼ 0.35 ± 0.02...

The evaluation of liquefaction effect on the dynamic moment of stabilizing piles is potentially significant. Based on the dynamic centrifuge modeling of a slope reinforced with a row of copper model pile, this paper not only analyzed the response of dynamic pore pressure, earthquake deformation and macroscopic phenomenon measured in the response of the reinforced slope, but also simulated the r...

Low food availability is a major structuring force in deep-sea benthic communities, sustaining only very low densities of organisms in parts of the abyss. These low population densities may result in an Allee effect, whereby local reproductive success is inhibited, and populations are maintained by larval dispersal from bathyal slopes. This slope-abyss source-sink (SASS) hypothesis suggests tha...

We investigate the consequences of fluid flowing on a continuous surface upon the geometric and statistical distribution of the flow. We find that the ability of a surface to collect water by its mere geometrical shape is proportional to the curvature of the contour line divided by the local slope. Consequently, rivers tend to lie in locations of high curvature and flat slopes. Gaussian surface...

BACKGROUND Early childhood lead exposure is associated with numerous adverse health effects. Eliminating blood lead poisoning is a national health objective for 2020. OBJECTIVE To assess temporal trends in childhood elevated blood lead level (EBLL) rates. METHODS Laboratory surveillance data were collected from 1997 to 2011 and analyzed in 2013 using linear regression to assess trends in co...
