Composting of aged reed bed biosolids for beneficial reuse: a case study in New Jersey, USA
No full textReed beds with Phragmites australis (common reed) have been utilized to decrease the water, nutrient and volatile solids content of sewage sludge. An efficient disposal/reuse option was sought for reed bed biosolids accumulated over a 15 year period at a wastewater treatment facility in New Jersey, USA. The study facility had 14 reed beds, each with 1000 wet tons capacity, which were full, and so the solids needed to be removed. Because P. australis is considered an invasive species in New Jersey and several other states in the United States, disposal or reuse of solids containing this plant is regulated. Composting was examined as a potential treatment for destroying the plant’s reproductive rhizomes. The high temperatures achieved during composting were also tested to determine if regulatory criteria for pathogen reduction could be met, making the composted product suitable for unrestricted land application. Preliminary studies indicated the sludge had stabilized to the point where self-heating did not occur. Among the carbon amendments tested in the laboratory to stimulate compositing activity, Phragmites above ground biomass was determined to be most suitable. In a field test, Phragmites above ground biomass was mixed with reed bed biosolids at a 1:2 (w/w) ratio. The temperatures achieved resulted in complete mortality of Phragmites rhizomes. In laboratory tests, rhizomes placed in a drying oven at 50ºC for 24 hours, or 55ºC for 12 hours, showed 100% plant mortality. However, under field conditions pile temperatures could not be maintained long enough for the sludge to meet the USEPA 503 biosolids time-temperature pathogen rule requirements for unrestricted land application, even though sample fecal coliform counts did meet regulatory limits.Peer reviewed

No full textThe Contribution of the Publicly Funded R&D Capital to Productivity Growth and an application to the Greek food and beverages industry
No full textThis paper follows the dual cost function methodology and develops a theoretical specification that assesses the contribution of public R&D capital to the productivity growth. The empirical application focuses on Greek food and beverages industry. For this purpose it employs a micro-aggregated annual data set over the period 1976-2002. The regression analysis shows that publicly funded R&D capital is a productive input as 8.7 percent and 7.3 percent of the total factor productivity growth in the food industry and in the beverages industry respectively is attributed to the publicly funded R&D capital. The relationship between publicly funded R&D and private purchased inputs is also examined.Public R&D; Productivity Growth; Rate of return.
Letter From Carl R. Gray, Jr., Concerning Cancellations of Veterans Hospital Projects in South Carolina
No full textFluorometric quantitation of fluorescein-coupled antibodies attached to the cell membrane.
No full textA method was devised which allows the measurement, by direct and indirect fluorescence assay, of the binding of fluorescein-coupled antibodies directed against cell-membrane antigens. The systems used were: (1) species-specific antigens, (2) genetically determined isoantigens, (3) virus-determined, tumor-specific antigens, and (4) membrane-bound immunoglobulin in a Burkitt cell line. Titration of antibodies gave straight lines in the log versus log scale, the slope of the titration curve probably being dependent on the density of antigen receptors on the cell surface
