Current uptake of 15N –labeled ammonium and nitrate in flooded and non-flooded black spruce and tamarack seedlings.
Download2009
Macdonald, S. Ellen, Islam, M. Anisul
We investigated the effects of flooding for three weeks on physiological responses and uptake of NH4+ and NO3- by black spruce (Picea mariana (Mill.) BSP.) and tamarack (Larix laricina (Du Roi) K. Koch) seedlings fertilized with labeled (15NH4)2SO4 or K15NO3 in a growth chamber experiment....

Decline and partial rebound of the Labrador Current 1993-2004: Monitoring ocean currents from altimetric and conductivity-temperature-depth data
Download2010
Chen, Nancy, Ohashi, Kyoko, Fischer, Jürgen, Myers, Paul G., Han, Guoqi, Nunes, Nuno
Monitoring and understanding of Labrador Current variability is important because it is intimately linked to the meridional overturning circulation and the marine ecosystem off northeast North America. Nevertheless, knowledge of its decadal variability is inadequate because of scarcity of current...

Determination of biokinetic parameters of wastewater biofilms from oxygen concentration profiles
DownloadFall 2011
The process of scale-up and rational optimization of biofilm processes for effective wastewater treatment and reuse require better understanding of the biokinetic behavior of microorganisms in the biofilms. At present, no fast and accurate methods exist for determining kinetic parameters for...

Efficacy of conventional and novel antimicrobial treatments on the inactivation of desiccated cells and biofilms of Salmonella
DownloadSpring 2024
Repeated isolation of Salmonella from the dry and wet environments of the food industry poses a significant concern to human health. It is crucial to understand the influence of the various environmental conditions on Salmonella’s survival. The overall objective of this research was to evaluate...

First-principles calculations of equilibrium nitrogen isotope fractionations among aqueous ammonium, silicate minerals and salts
Download2021-03-15
Li, Yonghui, Li, Long, Wu, Zhongqing
Nitrogen isotopes are a robust tool to study geological nitrogen cycle between Earth’s reservoirs. However, the application of nitrogen isotope system to understanding geological processes has been limited by the lack of constraints on equilibrium isotope fractionation factors between mineral and...

Synthetic polymers are still widely used in today’s life despite all environmental issues attributed to them. Replacing synthetic polymers with natural biodegradable polymers has been considered as a way of reducing these environmental impacts partially, if not completely. Hydroxyporpyl xylan...
