Axonal elongation and the transformation of growth cones to synaptic terminals are major steps of brain development and the molecular mechanisms involved form the basis of the correct wiring of the nervous system. The same mechanisms may also contribute to the remodelling of nerve terminals that occurs in the adult brain, as a morphological substrate to(More)
Helicobacter pylori has acquired great importance during the last two decades, after being recognized as an important pathogen that infects a great portion of the human population. This microorganism is recognized as the main causal agent of chronic gastritis and duodenal ulcers, and it is associated with the subsequent development of gastric carcinoma. The(More)

In this paper we present our ongoing research about the integration of ubiquitous computing systems into classroom settings, in order to give basic support for some classroom and field activities. We have developed some web application components using Java technology and configured a classroom with wireless network access and a web camera for our purposes.(More)
An additional platform for supporting learning in the same physical space in which it takes place, is now available owing to the continuous advancement of wireless and mobile technologies. However, new challenges arise for the development of ubiquitous computing learning applications capable to provide appropriate content and services according to the(More)
