In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...

Enzymes are one of the most important biomolecules which has a wide range of applications in industrial as well as biomedical field. They are important due to their many useful properties. Their development, to a great extent, has been possible due to the availability of microbial sources. Microorganisms are of much attention because they can be produced economically and are amenable to genetic...

At the last Pig Genetics Workshop two papers described aspects of the lost potential in pig production at the commercial level. Black (2000) estimated that slower growth, reduced efficiency of feed use and fatter carcases decreased the profitability of pig enterprises by as much as 25%. Walters (2000) estimated that successful progress had been achieved in backfat reduction but that there were ...
