QUANTIFICATION OF THE OCEANOGRAPHIC CONTRIBUTORS TO TIME-VARIANCE IN THE UNDERWATER ACOUSTIC CHANNEL DURING THE DALCOMMS1 EXPERIMENT
(2018-12-10)Underwater acoustic communication is a key enabler for civilian and military applications such as ocean sampling networks, offshore exploration, pollution monitoring and underwater surveillance (Akyildiz et al., 2005). ... -
Quantifying and modelling nitrate leaching from a lettuce field in Annapolis valley Nova Scotia
(2015-04-02)Nitrate leaching (NO3-) from vegetable fields has become significant environmental issue in North America. The objective of this study was to evaluate the effect of timing and rate of nitrogen (N) fertilizer on lettuce ... -
Quantifying coastal cliff retreat using Structure-from-Motion photogrammetry in the Minas Basin, Nova Scotia
(2020-09-01)Rates of retreat of cliffed coastlines are increasing around the globe, but the causes of observed increases are unclear. Lack of understanding complicates assessment of the risks to coastal infrastructure associated with ... -
Quantifying hydraulic conductivity spatial variability for a cement-based solidification/stabilization (S/S) remediation project: a case study.
(Canadian Science Publishing, 2021)This paper presents statistical analyses of hydraulic conductivity data collected from an existing cement-based solidification/stabilization (S/S) system. The goal is to characterize the spatial variability of hydraulic ... -
QUANTIFYING IMPACTS OF SPATIAL RESOLUTION ON PIXEL AND OBJECT-BASED METHODS OF IMAGE CLASSIFICATION: A CASE STUDY OF IDENTIFYING ESTUARINE MORPHOLOGY IN COBEQUID BAY, NOVA SCOTIA, CANADA
(2020-04-15)Image processing methods can be used to classify land cover and phenomena fromsatellite imagery according to their spectral characteristics and identify target features. These methodscanprovide a relatively efficient ... -
Quantifying Land-use / Land Cover Change and Eutrophication in the Carleton River Watershed, Yarmouth County, Nova Scotia, Canada
(2018-04)A number of rivers and watershed systems in Southwestern Nova Scotia, Canada have experienced an increase in eutrophication promoting nutrients over the past three decades. As a consequence, artificial eutrophication and ... -
Quantifying nitrogen loading and corresponding eutrophication symptoms in 7 bays in eastern New Brunswick, Canada
(2015-02-25)Anthropogenic nitrogen loading has been identified as a significant cause of seagrass decline worldwide. In the Southern Gulf of St. Lawrence, eelgrass (Zostera marina) is the dominant macrophyte in shallow coastal bays ... -
Quantifying particle dispersal in aquatic sediments at short time scales: model selection
(2008)In a pulse-tracer experiment, a layer of tracer particles is added to the sediment-water interface, and the down-mixing of these particles is followed over a short time scale. Here, we compared different models (biodiffusion, ... -
Quantifying predation on planktonic larval stages of marine benthic invertebrates
(2017-08-30)This thesis enhances our ability to develop hypotheses on effects of predation on the ecology of larval marine benthic invertebrates. I evaluated the mechanisms that influence encounter rates among predators and prey, and ... -
Quantifying the Causes of Human-Black Bear Conflicts in Nova Scotia
(2021-04)Black bears are curious and will stop at nothing for a good meal. Unfortunately, Nova Scotian residents are seeing an increase in the presence of black bears around their properties and homes (Parsons pers. com., 2020). ... -
Quantifying the Impact of Media Supplementation on Cell Growth and Product Yield in Chinese Hamster Ovary (CHO) Cells
(2020-08-28)The optimization of cell growth and productivity is a major concern in the production of recombinant proteins in Chinese hamster ovary (CHO) cell cultures. Despite the frequency of media optimization in literature, there ... -
Quantifying the Impacts of Nova Scotia Forest Management Practices on Forest Stand Albedo and Surface Temperatures
(2024-04)In an effort to mitigate climate change, the Canadian government has increased focus on natural carbon sequestration through afforestation (i.e., the planting of forests where there were previously no forests) and reforestation ... -
Quantifying the patterns of functional connectivity within the brain during imagined and overt movement of a functional task in non-disabled systems
(2014-08-21)This project was aimed at quantifying functional connectivity within the brain during motor imagery (MI) and the actual performance of a motor task, and comparing these networks using graph theory. Fifteen participants ... -
QUANTIFYING THE SPATIAL AND TEMPORAL VARIATION OF THE AIR QUALITY HEALTH INDEX IN HALIFAX, NOVA SCOTIA
(2012-04-03)The AQHI, currently used by the Canadian government, is a multi-pollutant public health information tool that is based upon extensive Canadian epidemiological evidence. As the AQHI is a relatively new metric, there is ... -
Quantifying the Spatiotemporal PM2.5, Black Carbon, and Ultrafine Particle Concentrations Aboard Public Buses in Brazil: A Comparison of Three Cities
(2018-03-26)The transportation environment contributes disproportionately to air pollution exposure, despite the short amount of time spent in this microenvironment. Elevated concentrations of air pollution within bus passenger cabins ... -
Quantifying the temporal and spatial variation of atmospheric particles on Dalhousie Campus – a pilot study
(2009-04)Outdoor air pollution is a broad and complicated issue that poses a real threat to human health and the environment. Past research demonstrates a link between urban air pollution and increased rates of mortality and morbidity ...
