137Cs and (239+240)Pu data in seawater, sediment and biota from the regional seas of Asia-Pacific extending from 50 degrees N to 60 degrees S latitude and 60 degrees E to 180 degrees E longitude based on the Asia-Pacific Marine Radioactivity Database (ASPAMARD) are presented and discussed. 137Cs levels in surface seawater have been declining to its present(More)
A three-dimensional (3D) water circulation and contaminant transport model of Manila Bay has been developed with the aim of better understanding the formation and movement of harmful algal blooms. Radiotracer techniques were used to evaluate the model by recording the dispersion of a tracer at depths of 2 and 15 m near the injection point. The selected(More)
Ubiquitous learning (u-learning) is a new educational paradigm that takes place in a ubiquitous computing environment and allows proper content for learning at convenient place and time, thus matching the student features and needs. The development of u-learning applications requires considering the user characteristics and necessities and the complex set(More)
The ubiquitous learning is regarded as one of the new educational paradigms, where learning situations can happen anytime and anywhere. Computer systems that support such learning must manage a variety of information such as: differentiated characteristics of users, technology used and contexts in which learning takes shape. This implies that the copper(More)
The ubiquitous learning more than a technology phenomenon is a vision that challenges to review the educational environment to propose new educational settings, because it allows to make available to students a wide variety of educational resources, creates new and varied learning environments, personalizes learning and enables the realization of a series(More)
