Doppler SD-OCT Blood Flow Analysis and Extraneous Operator Influences
(University of Waterloo, 2014-01-30)Purpose: The RTVue-100 is a new instrument for measuring retinal blood flow (RBF), but image quality needs to be optimized in order for valid blood flow results. The primary aim of this thesis was to assess the presence ... -
Dose-dependent dissociation of pro-cognitive effects of donepezil on attention and cognitive flexibility in rhesus monkeys
(Elsevier, 2021-11)BACKGROUND Donepezil exerts pro-cognitive effects by non-selectively enhancing acetylcholine (ACh) across multiple brain systems. Two brain systems that mediate pro-cognitive effects of attentional control and cognitive ... -
Dose-effect autonomic responses to ocular surface stimulation
(University of Waterloo, 2018-04-26)Introduction: The ocular surface is one of the most densely innervated superficial tissues of the human body supplied extensively by autonomic and sensory nerve fibres. Studies have shown that ocular surface sensory neurons ... -
Double-pulse Model for the Study of Red-shifted Spectrum in Multi-frequency Raman Generation
(University of Waterloo, 2023-09-25)Multi-frequency Raman Generation (MRG) is a promising technique for generating few-femtosecond to sub-femtosecond pulses with high energy conversion efficiency. During transient MRG experiments coupled with two chirped ... -
Dreissenid Mussels and Large Lakes: Effects on Littoral Ecology
(University of Waterloo, 2010-10-28)Invasive organisms are one of the major threats to the ecological integrity of aquatic systems in the 21st century. Among the most notorious and important aquatic invasive organisms are the dreissenid mussels, Dreissena ... -
Driving Adsorbed Gold Nanoparticle Assembly by Merging Lipid Gel/Fluid Interfaces
(American Chemical Society, 2015-11-23)Surface forces between inorganic nanoparticles and lipid bilayer is of great relevance to biophysics, medicine, and nanobiotechnology. Adsorbed nanoparticles may influence the fluidity of the underlying lipids, which may ... -
Droplet formation in microfluidic T-junction generators operating in the transitional regime. I. Experimental observations
(American Physical Society Physics, 2012-01-26)This is the first part of a two-part study on the generation of droplets at a microfluidic T-junction operating in the transition regime where confinement of the droplet creates a large squeezing pressure that influences ... -
Droplet formation in microfluidic T-junction generators operating in the transitional regime. II. Modeling
(American Physical Society Physics, 2012-01-26)This is the second part of a two-part study on the generation of droplets at a microfluidic T-junction operating in the transition regime. In the preceding paper [Phys. Rev. E 85, 016322 (2012)], we presented our experimental ... -
Droplet formation in microfluidic T-junction generators operating in the transitional regime. III. Dynamic surfactant effects
(American Physical Society Physics, 2012-08-13)This study extends our previous work on droplet generation in microfluidic T-junction generators to include dynamic interfacial tension effects created by the presence of surfactants. In Paper I [T. Glawdel, C. Elbuken, ... -
Droplet Microfluidic System with On-Demand Trapping and Releasing of Droplet for Drug Screening Applications
(American Chemical Society (ACS), 2017-01-03)96-Well plate has been the traditional method used for screening drug compounds libraries for potential bioactivity. Although this method has been proven successful in testing doseÐresponse analysis, the microliter consumption ... -
DsRNA-mediated antiviral immunity in fish cells: visualization, sensors, and innate immune responses
(University of Waterloo, 2018-06-15)The global aquaculture industry is a multibillion dollar business that is threatened by pathogens, including a wide array of aquatic viruses. Currently there are no antiviral treatments available to combat viral outbreaks, ... -
Dust Near Galactic HII Regions
(University of Waterloo, 2012-11-15)The distributions of physical properties, such as the temperature, mass, or density of the dust grains in molecular clouds near Galactic massive star forming regions are relatively poorly understood. These properties are ... -
Dynamic mechanical behaviour of nanoparticle loaded biodegradable PVA films for vaginal drug delivery
(Sage Publishing, 2018-03-01)In this study, we investigated the viscoelastic and mechanical behaviour of polyvinyl alcohol films formulated along with carrageenan, plasticizing agents (polyethylene glycol and glycerol), and when loaded with nanoparticles ... -
Dynamical Properties of Dark Matter Halo Mergers
(University of Waterloo, 2015-09-29)This thesis examines the nature of mixing and heating during the merging of single, isolated dark matter halos, as well as a short discussion of the statistical nature of repeated mergers in a cosmological setting. A small ... -
Dynamics and Inhibition of Class II Fructose 1,6-bisphosphate Aldolase
(University of Waterloo, 2009-04-24)It has been suggested for many decades that the essential and ubiquitous enzyme fructose 1,6-bisphosphate aldolase (FBA) could be a good drug target against bacteria and fungi, since lower organisms possess a metal-dependent ... -
Dynamics and phases of matter in open quantum many-body systems
