(University of Waterloo, 2011-06-14)Incorporating philanthropy into tourism, through practices such as volunteer tourism and non-governmental organization (NGO) work, is becoming an increasingly popular way for tourists to aid people of developing nations ... -
THE PHILOSOPHICAL SIGNIFICANCE OF QUINE'S D-THESIS
(University of Waterloo, 2016-02-02)The philosophical significance of Quine's D-thesis is considered. The D-thesis - "Any statement can be held true come what may, if we make drastic enough adjustments elsewhere in the system? (W.V.0. Quine, From a Logical ... -
Philosophy in Pieces: The Aphorisms of Nietzsche's Human, All Too Human and Wittgenstein's Philosophical Investigations
(University of Waterloo, 2012-09-28)This thesis considers the philosophical importance of the literary form of two aphoristic works of philosophy: Nietzsche’s Human, All Too Human and Wittgenstein’s Philosophical Investigations. Though both these German-speaking ... -
The Philosophy of Bioinformatics
(University of Waterloo, 2007-01-22)The development of bioinformatics as an influential biological field should interest philosophers of biology and philosophers of science in general. Bioinformatics contributes significantly to the development of biological ... -
Phosphor Coated UV-Responsive CCD Image Sensors
(University of Waterloo, 2002)Typical CCD image sensors are not sensitive to Ultra-Violet (UV) radiation, because the UV photons have a penetration depth of 2nm in the ~1µm thick polysilicon gate material. An inorganic phosphor coating was ... -
Phosphoric Acid Doped Polybenzimidazole-Based Membrane Electrode Assembly for a Highly Sensitive and Selective Acetone Gas Sensor
(University of Waterloo, 2018-08-03)The increase in demand for small, inexpensive and portable gas sensors, which are sensitive and reliable, have generated much of the research interest toward solid oxide metal-based acetone gas sensors. However, despite ... -
Phosphorus and Nitrogen Cycling in the Mediterranean Sea: Circulation, biogeochemistry and anthropogenic forcing
(University of Waterloo, 2017-04-28)The Mediterranean Sea (MS) is an oligotrophic marine basin despite being semi-enclosed with unusually low inorganic phosphorus (P) and nitrogen (N) concentrations, and high nitrate (NO₃):phosphate (PO₄) ratios comparative ... -
Phosphorus and nitrogen in the Al-Hawizeh marshes, southern Iraq
(University of Waterloo, 2008-08-22)Hour Al-Hawizeh is one of the biggest marshes within the Mesopotamian marshes of southern Iraq. This Hour has been functioned for centuries under natural conditions providing resources for local people, important habitat ... -
Phosphorus cycling by stream biofilms exposed to continuous and episodic loading patterns
(University of Waterloo, 2023-09-25)Anthropogenic activities have led to nutrient enrichment of streams, causing eutrophication of water bodies on a global scale. Eutrophication is frequently tied to an excessive influx of phosphorus (P); a crucial nutrient ... -
Phosphorus Legacies and Water Quality Risks: A Vulnerability-Based Framework in Southern Ontario
(University of Waterloo, 2019-12-20)Excess phosphorus (P) loading increases the frequency of harmful algal blooms (HABs), posing severe threats to drinking water security and aquatic ecosystems. Efforts to reduce the inputs of P to Canadian agricultural soils ... -
Phosphorus Removal and Recovery from Wastewater using Sorbent Technologies
(University of Waterloo, 2018-08-03)Phosphorus (P) is an essential nutrient in fertilizers that are necessary for food production. Wastewater may represent a renewable source of nutrients if methods for recovering P from dilute wastewater streams can be ... -
Phosphorus Responses to Soil Moisture in Southern Ontario Agricultural Soil
(University of Waterloo, 2022-04-29)Agricultural landscapes are known to increase phosphorus (P) losses to waterways, contributing to the eutrophication of freshwater surface water bodies. In cold agricultural regions, the nongrowing season drives annual P ... -
Phosphorus Sequestration for Control of Cyanobacterial Growth in Drinking Water Reservoirs
(University of Waterloo, 2016-10-05)Engineered drinking water reservoirs are designed to facilitate particle settling for reduction of turbidity prior to conveyance to a drinking water treatment plant (DWTP). Fine cohesive sediment particles can carry ... -
Photoaffinity Labels of Daptomycin
(University of Waterloo, 2014-05-23)Daptomycin (Dap) is a cyclic lipodepsipeptide antibiotic that is currently used in the treatment of bacterial infections caused by Staphylococcus aureus including the strains that are methicillin-resistant (MRSA), as well ... -
Photocatalytic Oxidation of Anesthetic Gases
(University of Waterloo, 2020-08-27)Inhaled anesthetics used in surgeries are typically volatile halogenated hydrocarbons. In a typical situation only 5% of the administered anesthetic is metabolized by the human body, while the remaining 95% is exhaled ... -
Photochemical Degradation of Chlorobenzene
(University of Waterloo, 2013-05-02)Persistent organic pollutants (POPs) are organic compounds of anthropogenic origin that have been linked to the development of cancer, neurobehavioural impairment, and immune system biochemical alterations. These chemicals ... -
