The explosion of on-line information has given rise to many query-based search engines (such as Alta Vista) and manually constructed topic hierarchies (such as Yahoo! ).

We examined the extent to which arbuscular mycorrhizal (AM) fungi root improved the acquisition of simple organic nitrogen (ON) compounds by their host plants. In a greenhouse-based study, we used quantum dots (fluorescent nanoparticles) to assess uptake of each of the 20 proteinaceous amino acids by AM-colonized versus uncolonized plants. We found that AM colonization increased uptake of pheny...

In order to access TCP/IP networks (mainly the Internet) through GSM links,. we have designed an architecture based in the indirect model of client/server interaction, where an intermediate element acts as a bridge between GSM and the rest of the data network. We have replaced the TCP connection in the client-proxy link with a simpler protocol. This allows maintaining the protocols in server ma...
