El karaoke como recurso en el aula

This article has a twofold aim: on the one hand, to present an educational activity and, on the other, to analyse the use of karaoke in the music classroom for learning new songs and promoting strategies to encourage students to play a more active role. The method for this research work is based on two projects carried out by two different groups. One group studies songs by copying them; the other group learns the songs by means of karaoke. The process and the findings suggest that karaoke can be used as a motivating tool that boosts students’ confidence and let them pretend they are 'real famous singers'. However, the findings also show that karaoke is not the best resource for learning songs

Estudio preliminar sobre la determinación de elementos traza en cervezas venezolanas por ICP-OES

The levels of several chemical elements were determined simultaneously in ten different beers of the Venezuelan market by ICP-OES. With the exception of chromium, beer does not provide important amounts of nutritional oligoelements. The average chromium content found (33 µg/L) is higher than one reported for USA's beer (10 µg/L) but smaller than another reported for Brazilian beer (66 µg/L). The average percentage of chromium RDA by beer consumption found for Venezuela (6.3%) is similar to that reported for Belgium (5%). Regarding toxic elements, one of the samples contained an elevated amount of aluminium, probably dissolved from the aluminium can.
