The copepod Diaptomus sanguineus begins diapause in permanent ponds in late March as an adaptation to avoid summer fish predation. During a study of copepod populations in two Rhode Island ponds, a severe drought dried one pond killing all fish. The second (control) pond did not dry, and no fish were killed. Before the drought copepods in the two ponds entered diapause on nearly the same date. ...

This study used particle size analysis to investigate the initial accumulation and trap efficiency of radiocesium ((137)Cs) in four irrigation ponds, ~4-5 months after the Fukushima Dai-ichi nuclear power plant (DNPP) accident. Trap efficiency, represented by the inventory of (137)Cs in pond sediment to the inventory of radiocesium in soil surrounding the pond (i.e., total (137)Cs inventory), w...

Recirculation of wood ash from energy production to forest soil improves the sustainability of this energy production form as recycled wood ash contains nutrients that otherwise would be lost at harvest. In addition, wood-ash is beneficial to many soils due to its inherent acid-neutralizing capabilities. However, wood ash has several ecosystem-perturbing effects like increased soil pH and pore ...

Two clinical isolates and an environmental isolate of Edwardsiella tarda biogroup 1 (ETB1), recovered from liver pus, the stool specimen and from the pond water of the village of the patient, diagnosed to have liver abscess, were found to be identical by protein fingerprinting and ribotyping. It can be construed that the pond water served as the source of infection. The epidemiological triad of...

This paper summarizes some of the information contained in a comprehensive document about the beneficial use of municipal waste combustion (MWC) residues. The document entitled "Beneficial Use and Recycling of Municipal Waste Combustion Residues A Comprehensive Resource Document", presents information from world-wide sources and contains numerous references. Information is presented on ash char...

Ash content of paper sheet is an important performance index in paper-making process. X-ray ash sensor based on the Fe-55 radiation principle can detect paper sheet ash content accurately. Here considering the influence of paper absolute dry fiber weight and moisture content, real online ash signal can be achieved by algorithm developing, data processing and signal compensation, and this signal...

The study evaluated the status of fish pond projects initiated in the 1980s on resource-poor farms in Guatemala and Panama. In both places, the host country and the United States Agency for International Development (USAID) provided financial assistance and Auburn University provided technical support to the respective governments. The study examined the impact of aquaculture technology, extens...

Application of bio-fuel by-product sugarcane bagasse ash SBA as. Including sugarcane bagasse ash SBA13, recycled paper mill waste4.as bagassios. In this paper, Bagasse ash can be utilized by replacing it with fly ash and lime in fly ash bricks. Trial bricks of size 230x100x75 mm were tested.bagasse ash SCBA, several trials were conducted to define optimum burning time and temperatures. SCBA use...

When fish are recovered from ponds, the effluent is often drained, presenting both an environmental challenge and an agricultural opportunity. The effects of irrigation with pond effluent and its interaction with applied fertilizer were assessed in a field experiment using French bean (Phaseolus vulgaris) and kale (Brassica oleracea) over two growing seasons near Sagana, Kenya. Fresh and dry ma...
