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…

There are different approaches used by mathematics teacher educators to help pre-service primary teachers develop the useful skills and knowledge required to teach mathematics. One of these approaches is concerned to learning to notice relevant aspects in mathematics teaching. But…

This paper describes the development of an image retrieval
system that combines probabilistic and ontological information1. The
process is divided in two different stages: indexing and retrieval. Three
information flows have been created with different kind of information
each one:…

The main contention in this paper is that the process of communicating scientific knowledge could be compared to the role of the translator as communicator (Hatim & Masón, 1997). Like the translator, the task of the scientist is to encode…

Content vocabulary may have different connotative values and different denotational meanings in different languages according to cultural idiosyncracy, manifested in culture-specific "key" meanings and culture-related scripts. Our claim here is that, even in all these cases involving the use of…

Purpose – Information and communication technologies have became pervasive in people’s lives and in this changing world education cannot remain anchored in old-fashioned models which ignore the evolution through which society is going. This paper seeks to present the gamble…

In this paper, a restricted domain question answering (QA) system is described. The design architecture of this QA system and the features that allow the adaptation of the QA system to the medical domain are also presented. The advantages of…

The pragmatic approach to translation implies the consideration of translation as a useful test case for understanding the role of language in social life. Under this view this article analyses the decision-making stage translators go through in the course of…

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…
