We argue that quality issues and didactical concerns of MOOCs may be overcome by relying on small Open Educational Resources, joining them into concise courses by gluing them together along predefined learning pathways with proper semantic annotations. This new approach to adaptive learning does not attempt to model the learner, but rather concentrates on… (More)
Nanoparticles (NPs) have been synthetized and studied to be incorporated in many industrial and medical applications in recent decades. Due to their different physical and chemical properties compared with bulk materials, researchers are focused to understand their interactions with the surroundings. Living organisms such as plants are exposed to these… (More)
Magnetic nanofibers of ZnFe(2)O(4) / γ-Fe(2)O(3) composite were synthesized by electrospinning from a sol-gel solution containing a molar ratio Fe/Zn of 3. The effects of the calcination temperature on the phase composition, particle size and magnetic properties have been investigated. Zinc ferrite fibers were obtained by calcinating the electrospun fibers… (More)
Enterprise interoperability is a tool for enhancing the competitiveness of firms, and its importance is brought out by the fact one of the EC's strategic aims is to accomplish interoperability among European firms by the year 2010. Nevertheless, in the particular case of the Valencian Region (Spain), research into enterprise interoperability is still badly… (More)
Words meaning 'all' in Seri include a verb, a pronoun (which often cooccurs with a coreferential NP), and an NP modifier. This paper explores the syntax of the constructions in which these words occur. It also explores the scope relationship between these words and negation, which seems to vary depending on a non-surface syntactic relation.
