Interpreting Satellite Remote Sensing Observations using a Chemical Transport Model: Implications for Processes affecting Tropospheric NOx and Ozone
Nitrogen oxides (NOx = NO + NO2) and ozone (O3) play important roles in the troposphere that impact air quality and climate. This thesis presents three projects that demonstrate how satellite observations interpreted with ... -
IDENTIFICATION OF AMINO ACIDS INVOLVED IN THE MOONLIGHTING FUNCTIONS OF HTPB, THE LEGIONELLA PNEUMOPHILA CHAPERONIN
Chaperonin 60s (Cpn60s) and their cognate co-chaperonin 10s (Cpn10s) are highly conserved housekeeping proteins that provide favorable conditions for the correct folding of other proteins. The Cpn60/10 of Escherichia coli ... -
The impact of estrogen and the cAMP/PKA pathway on male-female differences in SR calcium release in murine cardiomyocytes
This study investigated the cellular mechanisms involved in the initiation and regulation of Ca2+ release and contraction in ventricular myocytes from male and female mice. Results showed that Ca2+ transients were smaller ... -
The Diversity and Origins of Mitochondrion-Related Organelles
Multiple distantly-related eukaryotic lineages have adapted to low-oxygen environments, and possess modified mitochondria, known as mitochondrion-related organelles (MROs). Although relatively few MROs have been investigated ... -
Undefeated Ambition in an Unsympathetic Empire: the Kat River Settlement in the Cape Colony, 1853-1872
The Kat River Settlement, established in South Africa’s eastern Cape in 1829, became a place where Khoesan Christians built an independent outpost of respectable colonial society. The Settlement lost official and missionary ... -
STUDYING THE ROLE OF THE DIVALENT METAL CATION ACTIVATOR OF THE CAMBIALISTIC ENZYME MANDELATE RACEMASE
Mandalate racemase (MR) from Pseudomonas putida requires a divalent metal cation, usually Mg2+, to catalyze the interconversion of the enantiomers of mandelate. Typical of a cambialistic enzyme, the active site Mg2+ ... -
Physical Properties of Nanotube Materials
In this work, carbon nanotube (CNT) yarns were prepared and annealed at temperatures up to 2700 °C in Ar atmosphere. Raman spectroscopy showed a four fold increase in the relative CNT crystallinity after annealing to 2700 ... -
INSIGHTS INTO THE ROLE OF COMPLEMENT DURING INTESTINAL INFLAMMATION
Complement is arguably the most ancient and effective innate defensesystemthat can also promote pathogenesis in multiple disorders. The focus of this study was to understand the impact of complement in diseases of the ... -
Design of a Cardiovascular Flow Mimicking Pump
In vitro testing is an important part of the development of new cardiovascular prosthesis designs. One important aspect of simulating the cardiovascular system is properly modeling the pulsatile flow created by the heart. ... -
Toward Understanding Cranial Sutures in Zebrafish and Chicken
Cranial sutures are the fibrous joints between the intramembranous bones of the skull roof that enable the skull to grow in size during the development and growth of the brain. Although the skulls of vertebrate model ... -
Contributions Of DNA Sequence Elements, Plasmid-Encoded Proteins And Host Proteins To Maintenance Of The Yeast 2-Micron Plasmid
The 2-micron plasmid is found at high copy in the nuclei of most strains of the budding yeast Saccharomyces cerevisiae. Despite conferring no selective advantage to its host, the plasmid is able to persist due to mechanisms ... -
Canadian Counsellors’ Views of Working with Individuals Considering Third Party Reproduction
Assisted Human Reproduction has altered the way people can achieve parenthood; individuals, families and nations have had to adjust. In Canada the lack of legislation for this rapidly growing area of privatized medicine ... -
Powder Metallurgical Processing of Titanium Alloys and Aluminides
In this thesis, the economical powder metallurgical approach was investigated to produce two Ti binary alloys (i.e. Ti-Ni and Ti-Sn) and a Ti-48Al based intermetallic alloy. In the first part of the work, Ni and Sn (up to ... -
Foraging and Roosting Habitat Use of Nesting Bank Swallows in Sackville, NB
Habitat loss and degradation caused by agricultural intensification is considered to play a leading role in the declines of aerial insectivores, making the understanding of habitat dynamics critical for protection of this ... -
IF YOU SEE WHAT I SEE, THEN I KNOW HOW YOU FEEL: HOW SCENE CONTEXT AND FACIAL MIMICRY DIFFERENTIALLY AFFECT SITUATED RECOGNITION OF DYNAMIC AND STATIC EXPRESSIONS
Testing facial expression recognition has primarily relied on facial stimuli consisting of static images of posed expressions or computer generated animations. In recent years, the ecological validity of results based on ... -
Ensemble Learning for Visual Recognition
Due to the widespread availability of affordable mobile cameras and popularity of social networking, a large variety of visual-based applications are emerging. These diverse applications have attracted many researchers and ... -
THE ROLE OF HEME REGULATORY ENZYMES IN MYOCYTES UNDER STRESS
The heme metabolism pathway remains a novel therapeutic target for heart failure treatment. However, how heme is regulated in the failing heart remains to be understood. To investigate the molecular mechanisms underlying ... -
A FUTURE FOR A FORGOTTEN PREDATOR: ASSESSMENT OF THE GLOBAL AND REGIONAL LEGAL FRAMEWORKS FOR PROTECTION AND RECOVERY OF THE CARIBBEAN SAWFISHES PRISTIS PRISTIS AND PRISTIS PECTINATA AND RECOMMENDATIONS FOR THE COURSE FORWARD
Two species of sawfish, Pristis pristis and Pristis pectinata, used to be common in the coastal waters of the Caribbean Region. However, due to direct and incidental fishing pressures, national and international trade in ... -
ENHANCEMENT OF BIOLOGICAL ACTIVITY IN BIOFILTERS BY AMINO ACID SUPPLEMENTATION
To achieve optimal growth during biological filtration a balance of available carbon (substrate) and nutrients such as nitrogen and phosphorus should be available for biological growth. The literature has suggested a carbon ... -
"There's Nothing Mild About It:" The Lived Experience of Mild Traumatic Brain Injury (MTBI) From An Occupational Perspective
This study explored everyday life for six individuals diagnosed with mild traumatic brain injury (MTBI) at least one year earlier. Using a phenomenological design, two in-depth interviews with each person explored occupations ...
