In an optimal medium, cell growth, antifungal activity, and antifungal compound production could be increased 2.7-fold, 4.1-fold, and 13.4-fold, respectively. A crude(More)
Ubiquitous computing environment requirement needs information sharing of sensors based on sensor network technology, situation-aware and determination functions and other related technologies ranging to appropriate and effective action processing. The sensor field independent information access is most important issues in everywhere under the ubiquitous(More)
