Spatial and temporal analysis of pharmaceutical concentrations and chitobiase activity in the Upper Tennessee River
… developed utilizing solid phase extraction and ultra-performance liquid chromatography (UPLC) interfaced with an electrospray ionization, tandem mass spectrometer (MS/MS). This method yielded reproducible quantitation at the low parts per trillion (ng/L) level for all 14 analytes (acetaminophen, …

Enhanced vermiremediation of hydrocarbon contaminated land using biosurfactant: an integrated approach
… relationship over a 28-day period was conducted. Ultra-performance liquid chromatography (UPLC) analysis showed that both EROD and MROD activities were induced between days 0 and 2 of exposure. The level of increase in enzymatic activities were similar in both genera (between 2 and 2.5-fold higher …

Optimizing nitrogen fertilization practices under intensive vineyard cover cropping floor management systems
Under-trellis cover crops have become more prevalent in East Coast grape growing regions through either intentional planting or adoption of native vegetation, to minimize the potential for erosion and to help regulate grapevine size and vigor. These companion crops, however, have sometimes resulted …

Evaluation of Nitrogen Management Schemes in Cover Cropped Vineyards
Vineyards in the Eastern United States are often prone to excessive vegetative growth. In order to suppress excessive vine vigor, many viticulturists have employed cover cropping strategies. Cover crops provide a myriad of agronomic benefits, however they are known to compete with the vine for …
