Ano: 1988 URL: http://eprints.nwisrl.ars.usda.gov/800/1/637.pdf Cast-in-Place 2-Foot Concrete Trapezoidal Flow-Measuring Flumes NWISRL Humpherys, A.S.; Bondurant, J.A.. Procedures are presented for casting 50-ft^2/sec trapezoidal water measurement flumes in 2-foot bottom width lined and unlined ditches. Drawings and construction details for the concrete forms used are also presented. Flumes installed in concrete-lined ditches require about 13 man-hours and cost about $230. Flow can be determined for both free and submerged flow conditions from rating tables with depth measured in a sitting well or with a sloping gage on the flue sidewall.

Ano: 1977 URL: http://eprints.nwisrl.ars.usda.gov/1143/1/394.pdf Ethanol production of semi-simultaneous saccharification and fermentation from mixture of cotton gin waste and recycled paper sludge NWISRL Shen, Jiacheng, J.; Foster, A.A., A.A.. Ethanol production from the steam-exploded mixture of 75% cotton gin waste and 25% recycled paper sludge in various conditions was investigated by semisimultaneous saccharification and fermentation (SSSF) consisting of a pre-hydrolysis and a simultaneous saccharification and fermentation (SSF). Four cases were studied: 24-h pre-hydrolysis + 48-h SSF (SSSF 24), 12-h pre-hydrolysis + 60-h SSF (SSSF 12), 72-h SSF, and 48-h hydrolysis + 24-h fermentation (SHF). The ethanol concentration, yield, and productivity of SSSF 24 were higher than those of the other operations. A model of SSF was used to simulate the data for four components in SSF. The analysis of the reaction rates of cellobiose, glucose, cell, and ethanol using the model and the parameters from... Tipo: Article Palavras-chave: Research methodology.

Ano: 1994 URL: http://eprints.nwisrl.ars.usda.gov/1066/1/830.pdf Uptake coefficients for biosolids-amended dryland winter wheat NWISRL Barbarack, K.A.; Ippolito, J.A.; McDaniel, J.. Biosolids regulations developed in the United States employed risk assessment impacts of trace element additions on plant uptake. The US Environmental Protection Agency adapted the uptake coefficient (ratio of plant concentration to quantity of element added) when developing limitations on selected elemental additions. The nature of the risk assessment requires uptake coefficients to be constants. Our hypothesis was the uptake coefficient for copper, iron, molybdenum, nickel, phosphorus, and zinc for biosolids-amended dryland winter wheat decreases with multiple biosolids applications at the same location. We applied up to 10 applications to two sites (designated North Bennett A and B) in eastern Colorado at rates from 2.24 to 11.2 megagrams per...
