A model of sedimentation-consolidation processes in so-called clarifier-thickener units is given by a parabolic equation describing the evolution of the local solids concentration coupled with a version of the Stokes system for an incompressible fluid describing the motion of the mixture. In cylindrical coordinates, and if an axially symmetric solution is(More)
Women are more likely than men to develop psychopathology as a result of stress, but there is little research regarding the effects of a stressful condition and its treatment in female non-human animals, perhaps because of inherent hormonal activity. Recent studies have demonstrated that there are structural and functional differences between the dorsal and(More)
Continuously operated clarifier-thickener units can be modeled by a non-linear, scalar conservation law with a flux that involves two parameters that depend discontinuously on the space variable. This paper presents two numerical schemes for the solution of this equation that have formal second-order accuracy in both the time and space variable. One of the(More)
OBJECTIVE To determine the epidemiological profile of the patients who suffered traumatic brain injury (TBI) and were treated at the Dr. Rafael A. Calderón Guardia Hospital (HCG) Neurosurgery department, during the period from 2007 to 2012. MATERIAL AND METHODS An observational, descriptive, retrospective and cross section study was performed on all the(More)
