The Root Zone Water Quality Model (RZWQM, V 3.25) was used to simulate the effect of swine manure applications on nitrate-nitrogen (NO3-N) concentrations in subsurface drain water from continuous corn for Iowa soils. Measured values of subsurface drain flow, NO3-N concentrations in drainage water, and residual NO3-N in the soil profile from three chisel plow plots were available for the growing...

BACKGROUND Abdominal drains have been placed prophylactically and removed in liver resection without robust evidence. The present study was designed to establish the optimal time for removal of such drains. METHODS Data on abdominal prophylactic drains were analysed in a consecutive series of patients who underwent liver resection for malignancy between 2006 and 2009. Bilirubin levels in drai...

We investigate the influence of collective plasma modes in a field-effect transistor channel under different excitations and biasing conditions. First, we study the case of a device externally-excited by a harmonic optical beating or an electronic excitation and current-driven at the drain. The harmonic and continuous responses of the transistor are calculated using a pseudo-two-dimensional hyd...

Chest drains incorporate the use ofa one-way valve to drain fluid or air from the pleural cavity. The valve prevents back-flow of air and fluid into the pleural cavity. They are indicated for use when collections of fluid or air are present in the pleural space, and by draining the collection they restore eÖScient gaseous exchange. Little has heen written on the nursing managetnent of chest dra...

A set of different short term stress conditions are applied to AlGaN/GaN high electron mobility transistors and changes in the electronic behaviour of the gate stack and channel region are investigated by simultaneous gate and drain current low frequency noise measurements. Permanent degradation of gate current noise is observed during high gate reverse bias stress which is linked to defect cre...

A Disruption Tolerant Network (DTN) is characterized by scenarios where end-to-end connectivity is rarely available. Hence, in such networks, the use of existing ad hoc routing protocols may result on poor performance, since they rely on the existence of an end-to-end path between the source and destination nodes. This paper proposes a DTN routing strategy called DRAIN. Differently from other p...
