The Semantic Web purports to give computeraccessible meaning to the content of the World Wide Web. The rationale behind this project is to create an environment where all this information could be freely exchanged among diverse entities, yet retaining its…

It is interesting and important to compare, analyze and assess the alternative tools that could be used in the area of Knowledge Representation. In this paper we present a reasearch line associated to this goal: to formally establish the relation…

Although some excellent Artículo de investigacións about Lyell's work have been published, they do not explicitly deal with Lyell's biogeographical conceptions. The purpose of this paper is to analyse Lyell's biogeographical model in terms of its own internal structure. Lyell…

The current state of science education in the United States is evolving to building a skills-based, rather than content-based, knowledge in its students, grades K-12. To this end, I have integrated my experience and understanding of molecular biology and educational…

Characterizations of the containment of a convex set either in an arbitrary convex set or in the complement of a finite union of convex sets (i.e., the set, described by reverse-convex inequalities) are given. These characterizations provide ways of verifying…

In polyandrous species, sexual selection acts both before (precopulatory) and after
(postcopulatory) mating on traits that are important for reproductive success. Precopulatory traits
are important for mate acquisition and include weapons and ornaments. Postcopulatory traits
