Characterization of Silver-Polyaniline-Epoxy Conductive Adhesives
(University of Waterloo, 2013-01-25)Electrical conductive adhesives (ECAs) containing silver filler and polyaniline co-filler were characterized for their electro-mechanical properties. Polyaniline is a conductive polymer and has a moderate conductivity in ... -
Characterization of Space Conditioning Loads for Energy Efficient Houses in Canada
(University of Waterloo, 2015-04-22)This thesis details the development of a graphical method of presenting equipment loads within a house, allowing the loads for an entire year to be presented on a psychrometric chart. These charts are called rosettes. This ... -
Characterization of Spot Weld Failure within Weld Groups under Predominantly Shear Loading
(University of Waterloo, 2020-11-02)This thesis examines the failure behaviour of spot welded connections in components using three different aluminium-silicon coated hot stamped steels, Ductibor® 500-AS, Ductibor® 1000-AS, and Usibor® 1500-AS, with 1.2 mm ... -
Characterization of Starch Nanoparticles by Fluorescence Techniques
(University of Waterloo, 2014-05-21)Abstract The properties of starch nanoparticles (SNPs) labeled with the fluorescent dye pyrene (Py-SNPs) were probed by using fluorescence quenching, pyrene excimer formation, and transmission electron microscopy (TEM). ... -
Characterization of Structural Adhesives Using Lap Shear and Pin and Collar Tests
(University of Waterloo, 2015-10-05)Increasingly stringent government regulations on vehicle fuel economy and emission standards have challenged auto manufacturers to improve the fuel economy of cars built for sale in North America. Lightweighting vehicles ... -
Characterization of Surface Urban Heat Island in the Greater Toronto Area Using Thermal Infrared Satellite Imagery
(University of Waterloo, 2016-01-08)For the past decades, there have been increasing concerns about urban environmental degradation, especially under the circumstance of urbanization. This thesis compares the trends between air temperature and surface ... -
Characterization of Tertiary Membrane Fouling in Cold Climates
(University of Waterloo, 2022-01-13)Cold climates have limited the application of membrane technologies in tertiary treatment by affecting both secondary biological and tertiary membrane processes. There is a need to develop a fundamental understanding of ... -
Characterization of the association of Dbf4 and Cdc7 with Mcm2-7 and chromatin in Saccharomyces cerevisiae.
(University of Waterloo, 2012-01-03)Initiation of DNA replication requires the action of the Dbf4/Cdc7 kinase complex (DDK) which is also a phosphorylation target of Rad53 kinase in the S-phase checkpoint. DDK is thought to trigger DNA replication by ... -
Characterization of the Behaviour of Solution-Responsive Polymers by Fluorescence
(University of Waterloo, 2014-04-17)Two families of amphiphilic polymers were characterized with respect to their ability to respond to changing solution conditions using steady-state and time-resolved fluorescence. Firstly, a series of 5 sequential amphiphilic ... -
Characterization of the chloroplast protein import receptors in the single-cell C4 species Bienertia sinuspersici
(University of Waterloo, 2012-04-25)Bienertia sinuspersici is one of the three currently known land plants which perform C4 photosynthesis without the conventional dual-cell system, but rather through intracellular compartmentation of organelles and enzymes ... -
Characterization of the Conformation and Internal Backbone Dynamics of a-Polyglucans by Pyrene Excimer Fluorescence
