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…

We study the effects of proximity in the interconnections between Internet providers participating at the three main Italian Internet Exchange Points. We find that geographical proximity plays a role in driving Internet Providers’ interconnection, positively affecting the likelihood of an…

In big companies, managerial activities and organizational boundaries will over time hide most unevenly developed skill and knowledge distribution patterns; studying the organizations with the means of modern applied physics is thus quite difficult. People are forced to communicate along…

Problematic aspects of intercultural communication are considered in the context of: an increasingly internationalized market for higher education; the globalization of knowledge; the compatibility of distinct national higher education cultures; and the capacity for successful cross-cultural cooperation. This is exemplified…

Ensuring environmental sustainability is the aim of the seventh Millennium Development Goal (MDG7). United Nations data shows insufficient progress, especially in developing countries. In order to generate new information about this progress and the main barriers that hinder it, we…

While birdsong is a model system for animal communication studies, our knowledge is derived primarily from the study of only one sex and is therefore incomplete. The study of song in a role-reversed species would provide a unique opportunity 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…

Presented at the PRHE (Pedagogical Research in Higher Education) Conference 16-17 June 2008., This paper highlights aspects of our experience as “exploratory practitioners” researching
the use and the value of two modes of assessment (web-based discourse and sketchbook
learning journals).…

Magnetic Resonance Imaging (MRI) is an important diagnostic imaging tool that has
seen rapid expansion in recent years with a commensurate increase in the number of
radiographers undertaking MRI scans. This imaging modality is a complex one and the strong
