An Assessment of a Wetland-Reservoir Wastewater Treatment and Reuse System Receiving Agricultural Drainage Water in Nova Scotia
(2010-10-04)A wastewater treatment and reuse system consisting of a tile drainage system, a constructed treatment wetland (CTW), a reservoir, and an irrigation system was established. The system supplied 780 mm of irrigation water ... -
Determination of the Effect of Nutrient Management Plans on Nitrate Concentrations in the Soil and Water Below the Root Zone in Commercial Potato Production.
(2011-04-15)Nitrate leaching from research and commercial potato rotations was evaluated using stainless steel zero tension lysimeters, tile drainage and soil samples. The effect of nutrient management versus conventional fertility ... -
An Energy Efficient Thermally Regulated Optical Cell for Lab-on-Chip Devices: Applied to Nitrate and Nitrite Detection.
(2023-08-30)Reagent-based colourimetric analyzers that are intended to operate for significant durations in the field typically aim to conserve energy use per measurement. In many cases, the fluid under analysis must be elevated to ... -
Inlaid Microfluidics: A Novel Approach to Optical Measurements on Lab-on-Chip Devices
(2020-12-18)A novel type of microfluidic optical cell is presented here that inlays black poly(methyl methacrylate) (PMMA) into a clear PMMA substrate to realize an isolated optical channel with microlitre volumes. Optical measurements ... -
