Since online Semantic Web applications are based on existing Web infrastructure, developing these applications could leverage experiences with and infrastructure of existing frameworks. These frameworks need to be extended to deal with the different nature of Semantic Web data. We introduce several extensions to the Ruby on Rails Web development framework to support Semantic Web application dev...

At present, there are many communities of blogs that are connected to each other in a formal or informal manner, through blogroll links, casual references from posts or via sites set up as aggregators for communities of interest. However, there is much information in such communities that could be formalised for use in searching, browsing and viewing of blog posts either locally or using third-...

When migrating, people carry their cultural and genetic history, changing both the transmitting and the receiving populations. This phenomenon changes the structure of the population of a country. The question is how to analyze the impact on the border region. A demographic and geopolitical analysis of borders requires an interdisciplinary approach. An isonymic analysis can be a useful tool. Su...

The larger effort began when a number of communities (the CDM work at Unidata, the CSML work at BADC, and the OGC Sensor Web Enablement Observations and Measurements) realized they were developing similar lists of data types. The combined list includes: 1) grid, 2) point/station observation, 3) vertical profile/sounding, 4) trajectory, 5) swath, and 6) radar/radial. This paper details the curre...

To efficiently support collaborative semantic management of digital resources, this paper introduces MetaSemflow, a vertical semantic flow of metadata integration to capitalize on the diversity of available metadata sets. In this paper, we aim at applying our approach on digital resources shared between agricultural communities. MetaSemflow proposes a metadata inheritance integration by combini...

Bacterial biofilms are structured multicellular communities involved in a broad range of infections. Knowing how free-swimming bacteria adapt their motility mechanisms near surfaces is crucial for understanding the transition between planktonic and biofilm phenotypes. By translating microscopy movies into searchable databases of bacterial behavior, we identified fundamental type IV pili-driven ...

BaroVNAV is seen by the aviation industry as a major feature of the navigation infrastructure to support RNAV, RNP approaches and possibly precision approaches in the future. During discussions which occurred during the Navigation Systems Panel meeting, Montreal October 2005, the perspective of navigation systems experts on the limited integrity of BaroVNAV with respect to other vertical naviga...

Seasonal and spatial variation in soil nematode communities was investigated in a field study conducted on a loessial plain in the northern Negev Desert, Israel. Soil samples from 0- to 50-cm depths were collected seasonally during 2001 under the canopy of Atriplex halimus and Hammada scoparia, and between shrubs (control). Total population abundance ranged from 8 to 887 individuals per 100 g s...

Introduction This study was conducted in Brazil and Colombia,where dengue is endemic and vector control programs use chemical insecticides. Methods We identified knowledge, attitudes, and practices about dengue and determined the infestation levels of Aedes aegypti in one Brazilian and four Colombian communities. Results The surveys show knowledge of the vector, but little knowledge about diagn...

Constructed wetland technology has been widely applied around the world to treat domestic wastewaters from the single family home to small communities. Constructed wetlands can be classified as either surface flow wetlands (similar to natural wetlands) or subsurface flow wetlands, where the wastewater flows through a media. Subsurface flow constructed wetlands can either be horizontal flow syst...
