The effectiveness of a pervious concrete pavement to transport water through it depends on the intrinsic permeability of the system. However, this characteristic is usually defined in terms of the porosity of the material. It has been observed that porosity alone is an inadequate indicator of the permeability of pervious concretes, since the permeability depends on pore sizes, geometry and conn...

BACKGROUND Children in primary school are more physically active in the spring/summer. Little is known about the relative contributions of day length and weather, however, or about the underlying behavioral mediators. METHODS 325 British children aged 8 to 11 wore accelerometers as an objective measure of physical activity, measured in terms of mean activity counts. Children simultaneously co...

A novel online analysis method for software Interactive Behavior (IBs) is presented in the paper. Scenario-sensitive method is adopted to model complicated IBs among third party software entities. By fusing real-time self-experience and pervious experience based on knowledge, the creditability of interactive entities is computed automatically. Multi-Entity Bayesian Network (MEBN) tool is adopte...

this study was carried out to investigate the effects of dietary putrescine (put) on broiler’s response fed low crude protein (cp) diets. a total of 192 male day old chicks were fed with four dietary treatments including two levels of put (0 and 0.03%) and two levels of cp (normal and low) with factorial combinations. weekly growth performance, nutrient digestibility and intestinal morphology (...

Annual series of three stochastic rainfall model parameters — the seasonal wet day amount (or intensity), the conditional dry–day probability (or dry–spell persistence), and the conditional wet-day probability (or wet-spell persistence) — were examined using daily rainfall records for ten UK stations for the period 1901–1995. The purpose was first, to determine the extent to which these indices...
