Mobile transactions for updating spatial data are long-lived transactions that update local copies of the mobile platforms on disconnection. Since a mobile transaction is physically separated from its global transaction, the concurrent updates of mobile transactions should be merged into the global database after committing. Validation-based schemes, which are well-known to be appropriate for m...

It is the most common occupational lung disease in developed countries. One of causative agent is metal fume that may be encountered in steel industries. In this study we determined...
Due to the ever-increasing demand of world economy for aluminum, its alloys and compounds, production this metal is increasing annually throughout world. This leads an increase in industrial alumina, which obtained from bauxite ore Bayer process. After recovering bulk aluminum ore, there remains a residue highly alkaline toxic waste, also called residues (tailings) or red mud (RM). About 140-15...
In the past, Aedes atropalpus was limited to those areas of the eastern U.S. and Canada that had rivers or shorelines with large rocks containing rock pools.
