Characterization of acid phase anaerobic digestion of municipal sludges to improve biological nutrient removal processes
(University of Waterloo, 2017-10-24)Enhanced biological phosphorus removal (EBPR) can improve the balance sheet for waste water treatment plants. However, for phosphate accumulating organisms (PAOs) to work efficiently, there needs to be a readily biodegradable ... -
Characterization of Active Cellulolytic Consortia from Arctic Tundra
(University of Waterloo, 2011-05-20)The consortia of microorganisms responsible for the hydrolysis of cellulose in situ are at present poorly characterized. Nonetheless, the importance of these communities is underscored by their capacity for converting ... -
CHARACTERIZATION OF AHR SIGNALING AND THE IMPACT OF POLYCHLORINATED BIPHENYLS ON THE ADAPTIVE RESPONSES TO STRESS IN FISH
(University of Waterloo, 2007-09-13)Persistent organic pollutants (POPs), including polychlorinated biphenyls (PCBs) are widespread in aquatic systems. These toxicants bioaccumulate in the tissues of aquatic organisms, especially fish as they occupy a position ... -
Characterization of Alcohol Dehydrogenases from Hyperthermus butylicus
(University of Waterloo, 2016-01-22)Hyperthermophiles grow optimally at 80 oC and above, and many of them use carbohydrates and peptides for their growth. Hyperthermus butylicus is a peptide-fermenting hyperthermophilic archaeon producing 1-butanol as an ... -

(University of Waterloo, 2014-11-05)The baculovirus-insect cell system is one of the most widely used systems for recombinant protein production. The ease of handling insect cells and their ability to produce mammalian-like post-translational modifications, ... -
Characterization of Anaerobic Membrane Bioreactors (AnMBR) Treating Municipal Wastewater
(University of Waterloo, 2015-02-18)The study investigated the impact of solids retention time (SRT), hydraulic retention time (HRT) and the addition of FeCl3 on bioprocess and membrane performance of anaerobic membrane bioreactor (AnMBR) treating authentic ... -
Characterization of anaerobic membrane digesters for stabilization of waste activated sludge
(University of Waterloo, 2010-10-12)Anaerobic membrane bioreactors may provide a sustainable technological solution for digestion of waste activated sludge due to their capacity to achieve substantial volatile solids (VS) destruction and positive energy ... -
Characterization of Bacteriophage λ Displaying Epidermal Growth Factor in the Uptake, Infiltration and Formation of HT29 Spheroids
(University of Waterloo, 2019-07-31)Solid tumours are characterized by a complex structure comprised of extracellular matrix, neoplastic cells and stromal cells, each presenting a barrier to conventional anticancer chemotherapy as well as carrier-mediated ... -
A Characterization of Bromine and Chlorine Stable Isotopes in the Sand Hills Region of Nebraska, USA
(University of Waterloo, 2015-09-21)Saline lakes and salt flats are capable of releasing a significant flux of reactive bromine into the atmosphere, a compound which is 45-70 times more efficient at ozone destruction than chlorine (Eggenkamp, 2014; Risacher ... -
Characterization of Cadmium-Induced BiP Accumulation in Xenopus laevis A6 Kidney Epithelial Cells
(University of Waterloo, 2016-08-19)In vertebrates, cadmium exposure is found to cause respiratory, neurological and kidney disorders. At the cellular level, cadmium can damage or modify proteins resulting in the production of toxic protein aggregates. The ... -
Characterization of Carbon Nanotube Based Thin Film Field Emitter
(University of Waterloo, 2008-05-16)In recent years, carbon nanotubes (CNTs) have emerged as one of the best field emitters for a variety of technological applications. The field emitting cathodes have several advantages over the conventional thermionic ... -
Characterization of Changes in the Kidney, Liver, and Adipose Tissue of RTSAKO Mice
(University of Waterloo, 2018-11-02)Our laboratory has developed a novel genetic mouse model with kidney-specific lipid accumulation called RTSAKOs. The principle aim of my thesis was to study differences in the expression of genes and proteins related to ... -
The characterization of checkpoint kinase 2 in Oncorhynchus mykiss: Tissue specific expression suggests biomarker potential
(University of Waterloo, 2007-09-05)Chk2 is a cell cycle checkpoint kinase that is essential for initiating the DNA damage response in the presence of genetic damage. Its role is highly conserved from budding yeast (where it is named Rad53) to humans. Very ... -
Characterization of Competitive Oxidation Reactions Over a Model Pt-Pd/Al2O3 Diesel Oxidation Catalyst
(University of Waterloo, 2009-05-19)There has been a growing interest in using lean-burn engines due to their higher fuel economy and associated lower CO2 emissions. However, there are challenges in reducing NOX in an O2-rich (lean-burn) exhaust, and in low ... -
