ABSTRACT: Micronutrients availability is na important constraint for crops in the Cerrado region, and its correction is always needed to obtaining economic yields. Old and new nutritional problems came with the agriculture expansion in Cerrado. Although being crucial for increasing…

, What we know of polar expeditions coincides with a number of fictional and non fictional representations using different registers: the iconic-technical-scientific, the auto/biographical, the literary/fictional. This paper draws a comparison between texts featuring contrasting views on the character and…

In the modern age, Occidentalism as a process of signifying practices based upon the notion of “the West” has played a hegemonic role in the configuration of collective identity and alterity. The imaginary geography of “the West” has been one…

A re-design process implies dealing with complex interactions between stakeholders, especially if we are talking about a personalization re-engineered process, which can be applied to an existing web application. In this context, knowledge becomes a main factor of influence, but…

This work extends the semantics and implementation of fuzzy prolog presented in [VGM02] in order to include Default Knowledge capability. The new semantic allows non-uniform default assumptions and has Closed World Assumption (CWA) and Open World Assumption (OWA) as particular…

This paper uses dynamic general equilibrium and computational methods, inspired by the multi-sector growth model structure in Stephen Turnovsky's work, to develop a theory that unifies two of the traditional explanations of structural change: sector-biased technical change and non-homothetic preferences.…

Ontologies serve as a mean to establish a conceptually concise basis for communicating knowledge for many purposes. Within the information integration area, ontologies are useful to solve heterogeneity problems. They provide a set of knowledge terms, including the vocabulary, the…

The design of intelligent agents is greatly influenced by the many different models that exist to represent knowledge. It is essential that such agents have computationally adequate mechanisms to manage its knowledge, which more often than not is incomplete and/or…
