A Novel Method of Measuring Refractory Black Carbon Mass and Number Distributions by Inversion of CPMA-SP2 Data
DownloadFall 2017
A new method of examining mass and number distributions of nanoscale refractive black carbon (rBC) particles has been developed. This method will be useful for atmospheric scientists conducting semi-continuous measurement of atmospheric rBC. The new method uses a Centrifugal Particle Mass...

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...

Tooth length measurement accuracy and reliability with cone-beam CT and panoramic radiography
DownloadSpring 2010
This study assessed the accuracy and reliability of tooth length measurements through axial, coronal and sagittal serial slices of CBCT volumes; conventional panoramic radiographs; and CBCT panoramic reconstructions to that of a digital caliper gold standard. Samples consisted of maxillary...

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...

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,...

Adolescent Emotion Regulation Questionnaire: Development and Validation of a Measure of Emotion Regulation for Adolescents
DownloadFall 2011
The development of the Adolescent Emotion Regulation Questionnaire (AERQ) involved the creation of instrument items that were designed to measure emotion regulation strategies in cognitive, behavioral, physiological, and social response domains; intensity or duration emotional features; and...

Fall 2013
There is a general agreement that a relationship exists between health literacy (HL) and health outcomes. Nonetheless, there are critical gaps in the measurement of HL and in the evidence on the impact of inadequate HL on health outcomes, especially in the diabetes population. These gaps need to...

Autism spectrum disorder (ASD) impacts at least 1 in 68 individuals (Centres for Disease Control and Prevention, 2016) and though there are many treatments that can positively impact the condition, the adoption of evidence-based practices in community settings is slow (Dingfelder & Mandell,...

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...
