In the analysis of an acoustic radiation mode of a baffled plate, Rayleigh integral with free space Green’s function is involved. The boundary element method (BEM) is one of the approaches to compute its modes and radiation efficiencies. In this paper a fast multipole BEM in conjunction with an iterative solver based on the implicit restart Arnold method is proposed to efficiently and accuratel...

Background: Although anaerobic system has been successfully used for treating the strong industrial wastewater, its efficiency for low-strength wastewater as municipal wastewater is not satisfying. This study aimed to enhance the capability of an anaerobic baffled reactor (ABR) for treating municipal wastewater. Methods: A 7-L ABR with 5 compartments was operated for a 287-day period fed with ...

were isolated.1^ Here we report the production, isolation, structure elucidation, and biological activities of pacidamycins D (1), 4N (2), and 5T (3). A fresh culture of strain NRRL18730 was inoculated into four 250-ml baffled shake flasks, each containing 50 ml of seed medium consisting of glucose monohydrate 1.0%, soluble starch 1.5%, yeast extract 0.5%, casitone 0.5%, CaCO3 0.1% (pH adjusted...
