Adsorption and microflotation studies with pure minerals and an arylhydroxamic acid collector
(2009)
A study was conducted to understand the adsorption of N-hydrocinnamoyl-N-phenylhydroxyl-amine (HCNPHA) on the surfaces of various pure minerals: sphalerite, pyrite, galena, chalcopyrite and quartz. HCNPHA is a member of ...
Detection and characterization of DNA damage
(2009)
The DNA molecule is constantly subjected to endogenous and exogenous sources of damage which if left unrepaired can lead to genotoxic and cytotoxic outcomes. These lesions have been implicated in the development of numerous ...
Relating genecological variation in white spruce to ecological land classification in Central Canada
(2009)
Genetic diversity can be seen as a fundamental element in forest sustainability. Information about the genetics of trees can be obtained from provenance studies. Previous research has demonstrated that white spruce exhibits ...
Image-based visual servoing of a VTOL UAV
(2009)
Unmanned Aerial Vehicles (UAVs) are an area of significant research activity these days because of their use in dull, dangerous, and dirty tasks. Lack of human pilot paves the way for advanced and more sophisticated control ...
Ruthenium half-sandwich complexes containing novel anionic (phosphino) tetraphenylborate ligands
(2009)
In an attempt to expand upon previous work involving ruthenium-arene complexes bearing anionic (phosphino) tetraphenylborate ligands, and possibly provide further insight into the products obtained, a series of metal ...
Synthesis of novel Lipid A analogs as potential ligands for toll-like receptor 4
(2009)
Lipid A, the glycolipid component of Gram-negative bacterial lipopolysaccharide has been shown to engage the Toll-like receptor 4 (TLR4) signalling pathway. While this signalling cascade results in cellular mediators which ...
Wildfire dynamics of mixedwood boreal forests in central Canada
(2009)
Natural disturbances play a key role to forest regeneration, nutrient cycling, wildlife habitat, biodiversity, and climate regulation. A synthesis of literature indicated that boreal forest stand structure is largely a ...
Adapting to change, perceptions and knowledges in the involvement of Aboriginal peoples in forest management : a case study with Lac Seul First Nation
(2009)
This study examines the involvement of Aboriginal peoples in forest management and their perceptions and understandings of the forest, forest management, participation, consultation and Aboriginal and Treaty rights in ...
Effects of freezing on UV inactivation of waterbourne microorganisms
(2009)
In northern communities where source water may be frozen for parts of the year or wastewater is treated using freezing technology, the efficiency of UV inactivation may be affected. This research was carried out to investigate ...
Girl-child sexual abuse as a public health issue in Accra, Ghana
(2008)
Girl-Child Sexual Abuse (CSA) constitutes an alarming social phenomenon. Heavily influenced by social and cultural factors, CSA is understood and dealt with differently by different societies. Ultimately, survivors are ...
