Discarge compilation from The Global River Discharge (RivDIS) Project

The Global River Discharge (RivDIS) data set contains monthly discharge measurements for 1018 stations located throughout the world. The period of record varies widely from station to station, with a mean of 21.5 years. These data were digitized from published UNESCO archives by Charles Voromarty, Balaze Fekete, and B.A. Tucker of the Complex Systems Research Center (CSRC) at the University of New Hampshire. River discharge is typically measured through the use of a rating curve that relates local water level height to discharge. This rating curve is used to estimate discharge from the observed water level. The rating curves are periodically rechecked and recalibrated through on-site measurement of discharge and river stage.

Cost Reduction Effects of "pseudo FTAs" in Asia -Application of a price model based on a multilateral I/O table-

This paper examines the repercussion effects on the production cost of industries in Asian countries when some countries eliminate tariffs and import commodity taxes on all imports. This kind of analysis is related in some sense to that measuring the effects of FTAs on economies, and thus may be considered as an analysis of “pseudo FTAs.” Examining a number of combinations of “pseudo FTAs” between China, Japan, and ASEAN, it is found that the case of China plus Japan plus ASEAN is the most effective “pseudo FTA” of the combinations in terms of production cost reduction. The method is a form of price model based on the Asian International Input-Output Table. Almost no studies on price models related to multilateral I/O tables have been implemented thus far.

Experimental surgery to create subgenomes of Bacillus subtilis 168

The 4,188-kb circular genome of Bacillus subtilis 168 was artificially dissected into two stable circular chromosomes in vivo, one being the 3,878-kb main genome and the other the 310-kb subgenome that was recovered as covalently closed circular DNA in CsCl-ethidium bromide ultracentrifugation. The minimal requirements to physically separate the 310-kb DNA segment out of the genome were two interrepeat homologous sequences and an origin of DNA replication between them. The subgenome originated from the 1,255–1,551-kb region of the B. subtilis genome was essential for the cell to survive because the subgenome was not lost from the cell. The finding that the B. subtilis genome has a potential to be divided and the resulting two replicons stably maintained may shed light on origins and formation mechanisms of giant plasmids or second chromosomes present in many bacteria. Similar excision or its reversal process, i.e., integration of large sized covalently closed circular DNA pieces into the main genome, implies significant roles of subgenomes in the exchange of genetic information and size variation of bacterial genomes in bacterial evolution.
