An environmental water releases to the Snowy River was made in October 2011 (12,000 ML/day) as part of the Snowy River Increased Flows Program. The effects on the inlet entrance morphology and tidal response were measured on four field trips for each release to cover the flow peak and recovery. Water level recorders were deployed in the principal channels over the period of the releases and for...

The 3.0-3.1A X-ray structures of the cytochrome b(6)f complex from Mastigocladus laminosus and Chlamydomonas reinhardtii obtained in the presence of the p-side quinone-analogue inhibitor tridecyl-stigmatellin (TDS) are very similar. A difference occurs in the p-side binding position of TDS. In C.reinhardtii, TDS binds in the ring-in mode, as previously found for stigmatellin in X-ray structures...
