Fall 2023
Background: The COVID-19 pandemic has shown us that our infection prevention and control (IPC) knowledge has some glaring gaps on what best ways to treat dental patients, leading to a flurry of research to understand the best mitigation strategies to reduce aerosols. One of these strategies...

Characterization of Particulate Matter Morphology and Volatility for Two Direct-Injection Engines
DownloadFall 2015
Particulate matter emitted from two direct injection engines has been characterized by morphology, volatility, mass-mobility exponent, effective density, and size distribution using tandem measurements from a centrifugal particle mass analyzer (CPMA) and differential mobility analyzers (DMA). The...

The introduction of WNV into North America in 1999 was followed by rapid spread throughout the continent. Today, WNV is an endemic pathogen in the west, with thousands of cases of severe infection reported annually. In addition to traditional vaccine research, there is an urgent need to...

Development of Empirical Models to Predict Deposition of Aerosols in the Extrathoracic Airways of Children
DownloadSpring 2012
The experimental studies described in this thesis were performed with the goal of measuring deposition of aerosols, inhaled either nasally or orally, in the extrathoracic airways of children in different age groups. We pursued in vitro methods and characterized the deposition of aerosols in the...

Epithelial and vascular progenitors in the developing lung: Newer insights and therapeutic implications
DownloadFall 2012
Stanislaus Alphonse, Anthuvan Rajesh
Bronchopulmonary dysplasia (BPD) and congenital diaphragmatic hernia (CDH) are life-threatening lung diseases affecting newborn infants. Both diseases are characterized by impaired lung development and are currently untreatable. Dysregulation in the number or function of lung progenitor cells is...

Evaluation of Mask and Mask Material Suitability for COVID-19 Transmission Protection and Influence of Face Velocity and Exhaled Breath Condensate on Filtration Efficiency
DownloadSpring 2022
Facemask use has been a key public health measure in response to the SARS CoV-2 pandemic; they are used to reduce airborne transmission of the disease amongst the public. The facemasks used by the public are non-medical in nature and therefore are not regulated like medical masks. Cloth masks,...

Herpes Simplex Virus Requires VP11/12 to Activate Src Family Kinase-PI3 Kinase-Akt Signalling
DownloadFall 2010
This thesis defines a novel role for the Herpes Simplex Virus (HSV) tegument protein, virion protein (VP) 11/12 as a modulator of host cell signalling. Studies aimed at examining infection induced lymphocyte inactivation, revealed that VP11/12 is tyrosine phosphorylated in three lymphocyte...

Improving Measurements of the Mixing State and Mass Concentration of Particulate Emissions from Aircraft Engines
DownloadSpring 2016
This research is focused towards improving techniques used to measure particulate emissions from aircraft engines, on two fronts: first, to characterize and quantify the mixing state of particulate emissions; and second, to calibrate black carbon mass instruments with a traceable mass...

Spring 2018
The centrifugal particle mass analyzer (CPMA)-electrometer system has been proposed as an alternative method of calibration for devices that measure black carbon. This system is proposed to replace the current calibration standard of NIOSH 5040. The repeatability and intermediate precision of the...

Fall 2020
Infectious respiratory diseases, caused by viruses and bacteria that attack the respiratory system, constitute a serious threat in public health around the world. Pathogens can be transmitted in the air though large droplets or aerosols. As aerosols can linger in the environment for a prolonged...
