The Evaluation of the HUD Lead-Based Paint Hazard Control Grant Program (Evaluation) was a HUD-funded study of the effectiveness of lead hazard control (LHC) treatments conducted by 14 grantees in communities across the country. A stratified random sampling scheme was used to select treated units at four grantee sites for continued environmental assessment at 6 years post-intervention. The stud...

Northwest Africa (NWA) 5790 is the most recently discovered member of the nakhlite group. Its mineralogy differs from the other nakhlites with a high abundance mesostasis (38.1 3.6 vol%) and scarcity of olivine (4.0 2.2 vol%). Furthermore, zoning of augite phenocrysts, and other petrographic and chemical characteristics suggest that NWA 5790 samples the chilled margin of its parent lava flow/si...

Results of an experimental and theoretical study of the interaction of a first mode internal solitary wave with a localised bottom topography (sill) are presented. Laboratory experiments have been performed in a 10m long and 0.33m wide channel filled with a stratified fluid. The interface between the two layers (fresh and salt water) is diffuse and has a finite thickness. Soliton-type disturban...

Zooplankton in the ocean respond to visual and hydro-mechanical cues such as small-scale shear in turbulent flow. In addition, they form strong aggregations where currents intersect sloping bottoms. Strong and predictable tidal currents over a sill in Knight Inlet, Canada, make it an ideal location to investigate biological behaviour in turbulent cross-isobath flow. We examine acoustic data (38...

Directional variograms, along the soil profile, can be useful and precise tool that can be used to increase the precision of the assessment of soil pollution. The detail analysis of spatial variability in the soil profile can be also an important part of the standardization of soil magnetometry as a screening method for an assessment of soil pollution related to the dust deposition. The goal of...

Block ramps are ecofriendly drop structures, which ensure more stability in the downstream riverbed. The scouring stilling basin bed material generated by rapidly varied flow transition affects of ramp structure. In present study, a modified configuration is tested along with uniform conventional arrangements to check non-cohesive beds block ramps. Uniform horizontal configurations and sill arr...

[1] The multimodal structure of the baroclinic tides in the Strait of Gibraltar is studied using observations and numerical simulations. Observational data and model results revealed the presence of two types of tidal internal waves generated over Camarinal Sill (CS). One propagates toward the Mediterranean and disintegrates into series of nonlinear short internal waves with amplitudes of 50 m ...

Composite chondrocutaneous grafts were applied to 12 patients in various forms to repair the columellar deficit, to form the nasal tubercle and nostril sill in cleft lip nose patients. Cleft lip-nose deformity patients with alar cartilage hypoplasia, obtuse angulation of the medial and lateral crura and the resulting plica vestibularis, internal nasal valve problems associated with the weakness...

Eruptions at shield volcanoes often occur from radially aligned linear fissures fed by blade-like magma-filled cracks (dykes). The of the 2018 Sierra Negra eruption were scattered on flank volcano. Space-borne radar interferometric data (interferometric synthetic aperture radar) revealed that, unexpectedly, part was a 15 km long, tortuous and flat-lying crack (sill). Here we develop framework t...
