Heterogeneous azeotropic distillation is a widely used technique to separate binary azeotropic mixtures into their components. One of its most important applications is the dehydration of ethanol, which is blended with gasoline to obtain automobile fuel. Among all the compounds…

Design and optimization of distillation columns for ethanol dehydration, using a hydrocarbon as entrainer, implies a good knowledge of vapor-liquid (VLE), liquid-liquid (LLE) and vapor-liquid-liquid equilibrium (VLLE). Chemical process simulation programs always require the use of a thermodynamic model that…

El espacio Arquitectónico escolar evidencia la calidad socio comunicativa y transformadora de un grupo humano. Los centros educativos son espacios sociales, una de cuyas finalidades prioritarias es preparar a los estudiantes para que aprendan a conducirse y comprender las relaciones…

The chemical effects of acoustic cavitation are obtained in sono-reactors built-up from a vessel and an ultrasonic
source. In this paper, simulations of an existing sono-reactor are carried out, using a linear acoustics model, accounting
for the vibrations of the…

Le but de cette étude était de déterminer la contribution de plusieurs facteurs (le design de
la tâche, l’orientation d’angle, la position de la tête et du regard) sur la capacité des sujets à
percevoir les différences de formes bidimensionnelles…

El presente artículo hace referencia a la necesidad de considerar la evaluación de competencias cognitivas en el proceso educativo para lograr la formación de un ciudadano integral y consciente de la problemática ambiental. Estas competencias permiten, entre otras cosas, que…

L’insomnie, une condition fréquemment retrouvée dans la population, se caractérise d’abord par une difficulté à initier ou à maintenir le sommeil et/ou par des éveils précoces le matin ou encore par un sommeil non-réparateur. Lorsqu’elle n’est pas accompagnée par des…

Apart from speculating about a series of issues open to debate, such as the dark side of progress and globalization or the conflict between science and morality,
Margaret Atwood's Oryx and Crake (2003) offers a feasible insight into the state…

This article overviews the concepts of distributed intelligence, outlining the motivations for studying this field of research. First, common systems of distributed intelligence are classified based upon the types of interactions exhibited, since the type of interaction has relevance to…

An automatic disassembly cell requires of a
computer vision system for recognition and localization of
the products and each of theirs components. The detection
of occlusions adds more information to the knowledge base
to identify components and products, and generate…
