The rapid development of computer and Internet technologies has made e-Learning become an important learning method. There has been a considerable increase in the needs for multimedia instructional material in e-Learning recently as such content has been shown to attract a learner s attention and interests. The multimedia content alone, however, does not necessarily result in significant positi...

Witnessing the richness of data in document content and many ad-hoc efforts for finding such data, we propose a Data-oriented Content Query System (DoCQS), which is oriented towards fine granularity data of all types by searching directly into document content. DoCQS uses the relational model as the underlying data model, and offers a powerful and flexible Content Query Language (CQL) to adapt ...

Tomato bacterial wilt caused by Ralstonia solanacearum is one of the most destructive soil-borne diseases. Many strategies have been taken to improve soil suppressiveness against this destructive disease, but limited success has been achieved. In this study, a novel bioorganic fertilizer revealed a higher suppressive ability against bacterial wilt compared with several soil management methods i...

This study investigates patterns of plant diversity following wildfires in fire-prone shrublands of California, seeks to understand those patterns in terms of both local and landscape factors, and considers the implications for fire management. Ninety study sites were established following extensive wildfires in 1993, and 1000-m(2) plots were used to sample a variety of parameters. Data on comm...

Konni Forest Division, a part of Southern Western Ghats, on the bank of River Achencoil carries long history of man-forest interface and harbours rich floral diversity supporting three different eco regions. The present study aimed to assess the floral diversity of Konni Forest Division and its distribution in relation to various edaphic factors. Forest types are identified by reconnaissance su...

A much clearer picture of the progress towards an integrated high speed multi-service network is now emerging. Such networks were anticipated over twenty years ago, at a time when packet switching was just another way to transmit data. Now the technology is so mature that media barons are organising their investments in order to take advantage of the proot. Many of the technical problems are no...

Habitat fragmentation and invasive species often contribute to the decline of native taxa. Since the penetration of non-native species into natural habitat may be facilitated by habitat fragmentation, it is important to examine how these two factors interact. Previous research documented that, in contrast to most other arthropod taxa, spiders increased in density and morphospecies richness with...

Many regulatory authorities set water quality objectives or thresholds based on nutrient concentrations to safeguard aquatic ecosystem health. But do these criteria adequately assess the biological and ecological status? Our research has been focussing on the performance of constructed wetlands for water quality improvement and ecosystem health. In this paper we present data on macroinvertebrat...
