Evaluation of nitrogen availability indices
… surface and/or ground water resources. Field and laboratory studies were conducted to evaluate factors affecting the reliability of recommendations from three N availability indices and four laboratory methods to measure extractable organic N (EON), and the accuracy and repeatability of the Horiba …

The effect of homogenization upon the Vitamin C content of cow's milk
Series or experiments employing laboratory methods of homogenization were run at temperatures or 100°F, 110°F, 120°F, 130°F, 140°F, 150°F, 160°F, and 170°F and with pressures of 1000, 1750, and 2500 pounds at each temperature. In all series, at all temperatures and at all pressures, the results of …

A systematic and extensible approach to DNA primer design for whole gene synthesis
… whole genes by polymerase chain reaction methods. Yet, despite the improvement in laboratory methods, whole gene synthesis is not rapidly progressing because most gene design software takes an excessively naive approach to the complex problem of designing component oligonucleotides for …

A Comparative Microbial Composition Assessment of Stormwater, Urban Runoff and Wastewater
<p>The goal of this study was to compare two methods for assessment of fecal indicator bacteria (FIB) in urban runoff (n = 96), stormwater (n = 8), and wastewater (n = 16). We quantified the densities and reductions of E. coli and Enterococcus, in raw stormwater, treated urban off from the Santa …

Impacts of timber harvesting on soil physical properties in wetlands
… and saturated hydraulic conductivity (field and laboratory methods). Soil strength was not significantly different between disturbed and undisturbed areas. Overall, puddling resulted in soil changes that are more deleterious to tree growth than did compaction. Also puddling changes may prove more …

Hydraulic properties of asphalt concrete
… has applied standard unsaturated flow models and laboratory methods common to soil analysis, to characterize the hydraulic properties of asphalt concrete. Wetting and drying water characteristic curves were measured for six asphalt concrete cores. From the water characteristic curves, it is …

Modeling protein flexibility using collective modes of motion: Applications to drug design
… has proven a very difficult task. Experimental laboratory methods such as X-ray crystallography produce rather limited information, while computational methods such as molecular dynamics are too slow for routine use with large systems. In this work we show how to use the Principal Component …

Metal sludge thickening characteristics: particle density considerations
… objective was to attempt to apply various direct laboratory methods of wet particle density to the analysis of sludge floes. The second objective was to use the analysis of Javaheri and Dick (1969) to evaluate the thickening characteristics of four non-biological sludges including the relevance of …
