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 work was carried out throughout three academic years (2006/07, 2007/08, and 2008/09) within the context of assessment of teaching methods, following the implementation of new Module Guides in several modules representative of the programme in Business Studies of the…

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…

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 Millennium Development Goals (MDG) progress targets have not been met. Nevertheless, the United Nations (UN) has not yet undertaken in-depth review in order to discover the reasons behind this lack of progress in achieving the MDG. From a political…

In this paper a cross-disciplinary study of the use of epistemic markers as hedging rhetorical strategies in research articles in English is carried out. Based on computer readable data, and combining quantitative and
qualitative methods, the article argues that the…

This paper proposes a process management system that enables new dynamic manufacturing models to be implemented. This system facilitates the automation of process modelling, thus reducing the workload for process engineers. To this end, it focuses on the incorporation of…

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…

Web-based learning environments are becoming increasingly popular in higher education. One of the most important web-learning resources is the virtual laboratory (VL), which gives students an easy way for training and learning through the Internet. Moreover, on-line collaborative communication represents…
