Mountain rivers often receive sediment in the form of episodic, discrete pulses from a variety natural and anthropogenic processes. Once emplaced river, movement this depends on flow, grain size distribution, channel network geometry. Here, we simulate downstream bed elevation changes that result inputs (∼10,000 m3), differing volume under medium high flow conditions. We specifically focus comp...

BACKGROUND This study sought to identify in white women risk factors specific to binge-eating disorder (BED) and for psychiatric disorders in general, and to compare black and white women on risk factors for BED. METHOD A case-control design was used. Participants were recruited from the community and included 162 women who met DSM-IV criteria for BED and two comparison groups of women with n...

The H2S retention with Ca-based sorbents in a pressurized fixed-bed reactor (1 MPa) has been analyzed, obtaining the breakthrough curves with a dolomite and two different limestones, different particle size (+0.8-1.0 mm, +1.25-1.6 mm, and +1.6-2.0 mm), and both at calcining (1173 K) and non-calcining conditions (1123 K). The effect of the stoichiometric time in the breakthrough curves has been ...

OBJECTIVES We conducted a retrospective chart review of patients with differentiated thyroid cancer who underwent total thyroidectomy to examine the correlation of the persistence of thyroid bed nodules seen on ultrasonography with subsequent loco-regional recurrence. METHODS A total of 60 patients with differentiated thyroid cancer were identified who underwent total thyroidectomy, received ...

OBJECTIVE To share four Canadian cities' experiences with bed bug infestations and to explore public health roles in managing them. METHODS We summarize presentations from a workshop at the 2010 Canadian Public Health Association Conference which examined the re-emergence of bed bugs in Canada and compared management approaches of municipal and public health authorities in four large Canadian...

BACKGROUND Bleeding in the first trimester of pregnancy is a common phenomenon, associated with early pregnancy loss. In many instances a subchorionic hematoma is found sonographically. OBJECTIVE To evaluate the possible benefit of bed-rest in women with threatened abortion and sonographically proven subchorionic hematoma, and to examine the possible relationship of duration of vaginal bleedi...

In this work we incorporate the effect of near-bed coherent flow structures into the entrainment of randomly configured mixed-size sediments. The fourth-order Gram–Charlier type probability density function (GC pdf) of near-bed streamwise velocity is employed to account for the higher-order correlations associated with turbulent bursting. A compilation of the published data over a wide range of...

Understanding the mechanics of bed load at the flood scale is necessary to link hydrology to landscape evolution. Here we report on observations of the transport of coarse sediment tracer particles in a cobblebedded alluvial river and a step-pool bedrock tributary, at the individual flood and multi-annual timescales. Tracer particle data for each survey are composed of measured displacement len...
