This paper presents a new and alternative method (in the context of urban drainage) for probabilistic hydrodynamical analysis of drainage systems in general and especially prediction of combined sewer overflow. Using a probabilistic shell it is possible to implement both input and parameter uncertainties on an application of the commercial urban drainage model MOUSE combined with the probabilis...

In this paper a multijoint robot f o r sewer inspection tasks i s presented. In order t o increase the operating scope the robot has been made able t o run round or over obstacles, to follow sewage branches and is aimed t o work wirelessly unlike mos t other sewer inspection robots. A s a result of the wireless approach the robot has to carry an energy resource and mus t be able to act autonomo...

Nonpoint source urban nutrient loading into streams and receiving water bodies is widely recognized as a major environmental management challenge. A dominant research paradigm assumes that primarily derives from elevated stormwater. However, baseflow can account for large portion of total loading, especially low development intensity watersheds which comprise the largest areas. We investigated ...

Health degradation modifies Trp metabolism through induction of Trp catabolism. This could limit the amount of Trp available for growth. The aims of the present experiment were to investigate the effects of a low grade inflammation and dietary Trp on growth and Trp metabolism. Eighty weaned pigs were assigned to 4 experimental treatments according to a 2 x 2 factorial arrangement: 2 sanitary st...

Many older cities have “combined” sewer systems that collect both sewage and stormwater runoff in the same pipe for transport to a wastewater treatment plant. During heavy rainfalls, these combined systems can become overloaded, and water utilities must discharge the excess— what’s known as a combined sewer overflow (CSO)—into rivers and other water bodies, which may be the local source of drin...

Under the city of Barcelona, which has a population of three millions of habitants in an area of 98 Km, there is a complex sewage system with almost 1500 Km of length. That system is characterized for being unitary, that is, its collectors carry rain water and residual water. The yearly rainfall is not very high (600 mm/year), but it includes heavy storms typical of the Mediterranean climate th...

background: the hygienic issues are the essential criteria in the primary site selection, compatibility and maintain of passengers health after use of the services. qom with 17 million annual tourists is the second religious tourism center in iran. the aim of this study was to investigate the impact of the public residential centers internal managers’ educational status on their environmental h...

Feed restriction may be a strategy used by farmers to limit digestive disorders after weaning. The objective of this study was to evaluate the effect of feed restriction applied 1 wk after weaning on growth performance and health of pigs reared in 2 different sanitary conditions (Good vs. Poor; managed in opposite ways with respect to cleaning, animal density, and preventive antibiotic use) and...

We present an overview of a project that aimed to develop and implement computer vision techniques capable of extracting quantitative, three-dimensional descriptions of the shape of the surveyed pipe from sequences of images captured by an uncalibrated camera moving along a small-bore urban sewer. The resulting techniques are capable of use both on-line, during actual sewer surveys, and offline...
