Horizontal drains, used independently or as part of a more complex remediation scheme, are frequently installed to mitigate the effects of increased groundwater in slope stabilization projects. Due to a general trial and error approach to their design, the need for improved design practices has been recognized. The procedures established by Crenshaw and Santi in 2004 made some advances in this ...

The soil around a drain well is traditionally divided into smeared zone and undisturbed zone with constant hydraulic conductivity. In reality, hydraulic conductivity of the soil changes continuously and it may not be always appropriate to approximate its distribution with two zones. In this study, the horizontal hydraulic conductivity of the soil is described by an arbitrary function of radial ...

In most intracranial surgery cases, a drain catheter is inserted to prevent the collection of the wound hematoma or seroma. A drain catheter is also inserted to drain the hematoma or the cerebrospinal fluid. The drain catheter itself does not cause complications; but many complications occur during its removal, such as hematoma, seroma, air collection and pseudomeningocele formation. To prevent...

An analytic solution is presented describing ̄ow to a drain in a semi-in®nite domain bounded by a leaky layer of constant thickness. The solution is developed by applying the method of images to two parallel boundaries: an inhomogeneity boundary and an equipotential boundary. It is then demonstrated that the solution for the problem with the leaky layer approximated by a leaky boundary (a mixed...

The increase in energy demand, the scarcity of resources, as well adverse environmental impact burning fossil fuels make it necessary to diversify sources used. This also applies residential sector, which accounts for a significant proportion global consumption. Particular attention should be paid water heating, importance this process balance buildings is steadily increasing. One methods used ...

The integrity and issues related performance associated with scaling Si MOSFET channel length promotes research in new device SOI, double gate and GAA MOSFET. In this paper, we pr novel characteristic of horizontal rectangular gate MOSFETs with dual metal of gate we obtained using SILVACO TCAD tools. We will also exhibit some simulation results we obtained relating to the influence of some para...

Abstract Mine drainage from the St Louis Tunnel (located at Rico-Argentine Site) is circumneutral most of year, with spring freshets increasing flow, decreasing pH and metals concentrations. This study was designed to test performance a demonstration-scale horizontal wetlands passive treatment train, comprised settling basin, surface flow wetland, horizontal-flow anaerobic aeration channel, roc...
