Issues related to maternal mortality have generated a lot of empirical and theoretical information. However, despite the amount of work published on the topic, maternal mortality continues to occur at high rates and solutions to the problem are still not…

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…

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

This article aims to describe specific practices of television spectators based on
recordings of English families and friends while watching football on television. Their conversations and the talk and events on television are transcribed and analysed with interactional sociolinguistic and…

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…

Background: Operating Theatre Assistants (OTAs) deliver assistance in anaesthesia, surgery and recovery of patients. They require an adequate knowledge and competent clinical skills. In Sri Lanka this category of assistants does not receive any special training. Method: Operating theatre assistants…

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…
