plug-flow digesters with periodic loading mechanism are more enthusiastic than fully mechanized digestion plants for the majority of small or medium scale farms according to the costs and operational complexities. a dual-compartment plug-flow reactor equipped with a passive heating system was designed and experimentally operated by purpose of demonstrating a simple and low cost technology for ...

n this issue of Circulation: Cardiovascular Quality and Outcomes, Xu et al present findings from a search of US patents related to bare-metal coronary stents in an effort to gain insight on how medical device innovation starts and how policies in the United States might help to promote more innovation. 1 Of the 245 patents identified by their search strategy for the years 1984 to 1994, the auth...

The performance of many networking protocols is dependent on a handful of tuning parameters. However, it is not obvious how to set or adapt these parameters to optimize performance. We believe that this optimization task can benefit from passive monitoring of current network performance. In this paper, we apply this methodology for initializing TCP parameters, such as initial congestion window ...

“We boldly go where no man has gone before”. We want to announce new products and services and use matching supporting information systems. All this more rapidly than before and with higher quality. Thinking about time to market, you will come automatically to the question: “How to improve the process to be able to deliver more rapidly?” But the most important of all is not the process; it is t...
