An Investigation of Sloan Digital Sky Survey Data and Multi-Band Scaling Relations of Spiral Galaxies
(2010-09-19)We have compiled a large sample of 3041 spiral galaxies with multi-band $gri$ photometry from the the Sloan Digital Sky Survey (SDSS) Data Release 7 archive. We compare our own extracted photometry with data products ... -
Investigation of Softening Instability Phenomena Under Simulated Infinite Slope Conditions in Centrifuge Tilting Table Tests
(2014-05-01)Element test results reported in the literature under both triaxial and plane strain conditions indicate that loose saturated granular specimens can experience softening instability at stress ratios lower than what might ... -
An investigation of sugar-sweetened beverage consumption among Canadian youth
(2016-08-09)Background: Consumption of sugar-sweetened beverages (SSBs) is an important public health problem in Canada, especially among adolescents. Estimates show that rates of SSB consumption are particularly high in the northern ... -
AN INVESTIGATION OF THE BIOCHEMICAL PROPERTIES AND PHYSIOLOGICAL ROLES OF THE ARABIDOPSIS CALMODULIN-LIKE (CML) GENES CML15 AND CML16
(2016-01-14)Plants, as sessile organisms, require rapid and efficient signalling pathways in order to respond to environmental stimuli and to coordinate developmental programs. Stimulus-specific transient elevations in free cytosolic ... -
INVESTIGATION OF THE BIOTRANSFORMATION OF 4-(METHYLNITROSAMINO)-1-(3-PYRIDYL)-1-BUTANONE BY PROSTAGLANDIN H SYNTHASE AND CYTOCHROME P450 2F
(2008-01-15)The tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is believed to play a role in human lung cancer induced by tobacco smoking. NNK biotransformation may involve the enzymes prostaglandin ... -
Investigation of the Causal Factors for Enrollment and Satisfaction in Engineering
(2015-10-03)Undergraduate students at Queen’s University were surveyed and interviewed to examine the factors behind engineering program selection and academic transfer to engineering. The surveys were completed by 416 2nd-4th year ... -
INVESTIGATION OF THE COLLOIDAL BEHAVIOUR OF CARBON BLACK AND PERFLUOROSULFONATED IONOMER IN VARIOUS SOLVENTS
(2016-02-29)This thesis investigates the interactions between ionomer and carbon black in solution as influenced by different ink parameters. The motivation for this work is to collect necessary data that would lead toward the ... -
AN INVESTIGATION OF THE DELIQUESCENCE OF FERRICOPIAPITE AND THE ONSET OF DELIQUESCENCE OF EPSOMITE CRYSTAL FACES OF DIFFERING MILLER INDICES
(2011-01-12)Deliquescence is the process whereby a solid interacts with a humid atmosphere and begins to dissolve when the partial pressure of H2O in the atmosphere exceeds the partial pressure of H2O at which the solid is in equilibrium ... -
Investigation of the effect of intrauterine inflammation and infection on fetal brain injury using human and animal models
(2008-03-11)In recent years, increased focus has been placed on the role of intrauterine infection and inflammation in the pathogenesis of fetal brain injury leading to neurodevelopmental disorders such as cerebral palsy. At present, ... -
Investigation of the Effects of Biofouling on the Hydraulic Properties of Wells in Fractured Bedrock Aquifers
(2007-12-18)The objective of this study is to improve the understanding of the effect of biofilm growth and biofouling on well performance in a fractured rock aquifer. The study was conducted by investigating biofouling in several ... -
An investigation of the emotional modulation of pain perception and neural processing in the human brainstem and spinal cord using functional magnetic resonance imaging
(2014-12-11)Pain is an extremely subjective and complex sensory and emotional experience. It is affected by a range of factors including attention, suggestion, attitude, expectation, and affective state. The influence of emotion on ... -
