Spatial and temporal assessment of rural-urban land-use gradient effects on water quality and periphyton communities in tributaries of Durham Region, Ontario
(2016-08-01)
This study examines the effects of longitudinal and local land-use gradients on water quality and periphyton within four watersheds representing varying rural-urban land-use types and intensities. Although numerous studies ...
Bifurcation analysis of a nonlocal two-communication mechanism model for animal aggregation with O(2)-symmetry
(2016-12-19)
The study of animal aggregations has become a topic of great interest due to its practical
applications and theoretical significance. The common occurrence of these aggregations in
nature lead to a large variety of models ...
Direct Brønsted acid-catalyzed functionalization of benzhydryl alcohols and 2-ethoxytetrahydrofuran using potassium trifluoroborate salts
(2016-06-01)
Metal-free transformations of organotrifluoroborates are advantageous since they avoid using frequently expensive and sensitive transition metals. Lewis acid-catalyzed reactions involving organotrifluoroborates have emerged ...
Toward graph layout of large data visualization: algorithms, evaluations and application
(2016-01-01)
Generating layouts for millions of points on a spatially-restricted platform is a difficult
task with a unique set of constraints. These layouts are traditionally generated on a
server out of sight of the user. User-oriented ...
Improved 3D modelling of CANDU reactors using transport-fitted diffusion coefficients
(2016-12-01)
To model the neutronic physics behavior of the core in CANDU pressure tube type heavy water reactors with natural-uranium fuel, two levels of calculations are required. Initially, lattice-level transport calculations are ...
Strategies and applications for creating more memorable passwords
(2016-01-01)
As we continue to learn and grow in an ever evolving technological age, we deepen our
understanding of the importance of authentication. There are many different types of
authentication, each exhibiting their own strengths ...
Mathematical methods for 2D-3D cardiac image registration
(2016-12-01)
We propose a mathematical formulation aimed at intensity-based slice-to-volume registration,
aligning a cross-sectional slice of a 3D volume to a 2D image. The approach is
flexible and can accommodate various regularization ...
Influence of dietary interventions on the immune system: an investigation of the impact of omega-3 fatty acids, dietary fermentable materials and high energy diets
(2016-12-01)
Dietary interventions vary in ability to influence immune activity. Separate investigations were conducted to determine the immune impact of omega-3 fatty acids, dietary fermentable materials (DFM) and high energy (HE) ...
The modification of fuel cell-based breath alcohol sensor materials to improve water retention of sensing performance
(2016-03-01)
Fuel cell based breath alcohol sensors (BrASs) are one of the most important tools used by law enforcement today. While these devices are used globally, they all suffer from a common deficiency: reliance on water. The ...
Alloy catalysts for fuel cell-based alcohol sensors
(2016-05-01)
Direct ethanol fuel cells (DEFCs) are attractive from both economic and environmental standpoints for generating renewable energy and powering vehicles and portable electronic devices. The cost and performance of the DEFCs ...
