BACKGROUND The association between childhood exposure to lead (Pb) and deficits in cognitive function is well established. The association with prenatal exposure, however, is not well understood, even though the potential adverse effects are equally important. OBJECTIVES To evaluate the association between low prenatal exposure to lead and IQ in children, to determine whether there were sex d...

In the field of Geometric Function Theory, one can not deny the importance of analytic and univalent functions. The characteristics of these functions including their taylor series expansion, their coefficients in these representations as well as their associated functional inequalities have always attracted the researchers. In particular, Fekete-Szegö inequality is one of such vastly studied a...

Subsurface drainage is part of a sustainable system's components. This component represents the infiltration stormwater into subsurface system for flow attenuation purposes. study examines parameters The laboratory validation perforated drains was conducted at longitudinal slope gradient 1/500 with Gate Fully Open. manning, n data obtained in these experiments varies several hydraulic parameter...

In the present work the reflection behavior and the color appearance of acrylic yarns, as pile yarns used in carpet and pilled fabrics, are considered along their lengths as well as their cross- sections. Differences between longitudinal and cross-sectional reflection behaviors of yarns are measured in different yarn densities and hues and explained by the geometric model. The results of experi...

[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...

Quite simple and easy-to-use analytical dependencies for calculation of the main hydraulic structural characteristics distribution drainage pipelines, laid with a certain slope, are presented. They proposed on basis analysis differential equations system, which consists variable mass hydraulics equation modified filtration equation, describes fluid motion in such pipelines. The solutions origin...
