Ozone is known to be effective for achieving positive treatment effects on sludge characteristics. One of these effects is the reduction in excess sludge generation in wastewater treatment operations. This application is known for many years and full scale plants are installed and in operation. The economical success of this application strongly depends on the required ozone dose to reduce a ce...

—To assess the relationship between marsh area and relative abundance of tidal marsh bird species, we surveyed birds on 86 circular plots in 40 salt and brackish tidal marshes in Connecticut. We measured marsh area in two ways: the amount of contiguous marsh vegetation not interrupted by broad barriers (.500 m of open water or .50 m of upland habitat) and by narrow barriers (.30 m of open water...

—We conducted 262 call-broadcast point-count surveys (1–6 replicate surveys on each of 62 points) using standardized North American Marsh Bird Monitoring Protocols between 31 May and 7 July 2006 on St. Vincent National Wildlife Refuge, an island off the northwest coast of Florida. We conducted doubleblind multiple-observer surveys, paired morning and evening surveys, and paired morning and nigh...

Flavobacteriosis, in Switzerland caused mainly by Flavobacterium psychrophilum (Flavobaceriaceae), has become an important problem for the Swiss fish farming industry. While records of skin and gill infections have been described since a long time, systemic infections, known as the so-called rainbow trout fry syndrome (RTFS), have been reported for the first time not until 1992. Since then, occ...

Background: Prior research on the microorganisms associated with the brine shrimp, Artemia franciscana, has mainly been limited to culture-based identification techniques or feeding studies for aquaculture. Our objective was to identify bacteria and archaea associated with Artemia adults and encysted embryos to understand the role of microbes in the Artemia life cycle and, therefore, their impo...

Background: The function and structure of protein translocons at the outer and inner envelope membrane of chloroplasts (Toc and Tic complexes, respectively) are a subject of intensive research. One of the proteins that have been ascribed to the Tic complex is Tic62. This protein was proposed as a redox sensor protein and may possibly act as a regulator during the translocation process. Tic62 is...
