BACKGROUND In Canada the incidence of Fetal Alcohol Spectrum Disorder (FASD) is estimated to be 1 in 100 live births. FASD is the leading cause of developmental and cognitive disabilities in Canada. Only one study has examined the cost of FASD in Canada. In that study we did not include prospective data for infants under the age of one year, costs for(More)
Connected zones of high hydraulic conductivity in subsurface environments can constitute preferential pathways for contaminant transport and fluid flow. The identification of such pathways is important for well head protection, groundwater monitoring and capture system design for groundwater remediation. Since it is not practical to exhaustively sample the(More)
Subsurface characterization is important for investigations of groundwater contamination as well as petroleum extraction potential. Bore holes or drill logs are a common source of localized stratigraphic information. Sampling and interpolation uncertainties complicate the characterization of the subsurface from these data. Geostatistical methods (Kriging(More)
Automatic object detection is a rapidly evolving area in surveillance and autonomous vehicles. Deformable part model (DPM) is a well-known object detector for its high precision and speed bottleneck. This paper proposes a very fast object detection pipeline based on complementary techniques to accelerate DPM. A recent fast feature pyramid technique is(More)
OBJECTIVE To investigate blood lead levels in schoolchildren in two areas of Egypt to understand the current lead pollution exposure and its risk factors, aiming to improve prevention politicies. SUBJECTS AND METHOD This was a cross-sectional study in children (n=400) aged 6-12 years recruited from two areas in Egypt (industrial and urban). Blood lead(More)
OBJECTIVE To evaluate neopterin plasma concentrations in patients with active juvenile idiopathic arthritis (JIA) and correlate them with disease activity. METHODS Sixty patients diagnosed as active JIA, as well as another 60 apparently healthy age- and gender-matched children as controls, were recruited from the Pediatrics Allergy and Immunology Clinic,(More)
2 ACKNOWLEDGEMENTS The Adaptive Protocols for Lake Okeechobee Operations were developed to provide guidance in operations for protection of Lake Okeechobee and downstream ecosystems while providing a reliable water supply for agricultural and urban areas that depend on the Lake.
BACKGROUND In developing countries, Helicobacter pylori (H. pylori) infection is mainly acquired during childhood and may be a predisposing factor for peptic ulcer or gastric cancer later in life. Noninvasive diagnostic tools are particularly useful in children for screening tests and epidemiological studies. Data on serologic testing of children are(More)
