This book presents a query translation mechanism between heterogeneous peers in Peer to Peer Database Networks. A Peer to Peer Database Network combines a database management system with P2P functionality. In a such a network, each peer chooses its own data model and schema, and maintains data independently without any global coordinator. One of the problems in such a system is translating queries between peers taking into account both the schema and data heterogeneity. Query translation is the problem of rewriting a query posed in terms of one peer schema to a query in terms of another peer...

Thymidine analogue bearing a methyl ester at the C5 position were synthesized. Thermophilic family B DNA polymerases accepted these analogues as substrate to form the corresponding PCR product. Modified DNA containing this analogue were prepared by PCR with KOD Dash DNA polymerase and were further post-modified to form the corresponding derivatized DNA. These DNA could act as a template for PCR and could accept natural TTP or modified analogue as substrate. The thymidine analogue with an amino-linker was also reacted with fluorescein isothiocyanate, yielding a new analogue which was used as a...

The management of waste materials is becoming an acute problem in Malaysia. Rapid economic development, population growth, inadequate infrastructure and expertise and land scarcity make the management of municipal solid waste one of the Malaysia's most critical environmental issues. Solid waste management is a major challenge for Malaysia to address in the light of Vision 2020 which lays out the direction for Malaysia to become a fully developed nation by 2020. This book, therefore, provides a significant discussion on household waste management such as: Prevention and Minimization of Waste...
