We live in an era of profound changes in university education. The implementation of Bologna plan has led us to raise new teaching methodologies, to review the role of the student, competency assessment, the incorporation of ICT. Unthinkable acts, one or two decade ago. The TIC concept is very broad and is attributed to the media, processes and content usage. Inside the supports and platforms, we stress tools that allow automatic correction of exercises, because they are instruments of great educational value because instantly they assess students and provide instant feedback about the knowledge that they have either as message support or note. If the power of these tools, we add the Internet, using e-learning environment, the results allow us to work, edit, evaluate, resolve doubts, and so on, anywhere, anytime. We present part of a platform and the results of its use in the field of health sciences

Compositional data (concentrations) are common in geosciences. Neglecting its character mey lead to erroneous conclusions. Spurious correlation (K. Pearson, 1897) has disastrous consequences. On the basis of the pioneering work by J. Aitchison in the 1980s, a methodology free of these drawbacks is now available. The geometry of the símplex allows the representation of compositions using orthogonal co-ordinares, to which usual statistical methods can be applied, thus facilating computation ans analysis. The use of (log) ratios precludes the interpretation of single concentrations disregarding their relative character. A hydro-chemical data set is used to illustrate the point

Tot i que el cacau i la xocolata són una gran font de polifenols, aquests aliments no es troben entre les fonts alimentàries de polifenols més consumides. Algunes dades suggereixen un aport inferior al 10% de polifenols a través d’aquests. Aquest fet podria ser causa de les diferents metodologies i l'enfocament dels qüestionaris de freqüència de consum d'aliments (FFQ) utilitzats en aquests estudis. La majoria de FFQ validats utilitzen una extensa llista d'aliments per a les fruites i verdures, però no distingeixen adequadament les diverses fonts de xocolata i cacau. Aquests fets recolzen la necessitat d'una avaluació del consum de productes de cacau per tal de poder conèixer la ingesta real de cacau, especialment en la població jove, on la xocolata és un aliment consumit freqüentment.
