Fall 2016
Aerobic methanotrophic bacteria lessen the impact of the greenhouse gas methane (CH4) not only because they are a sink for atmospheric methane but also because they oxidize it before it is emitted to the atmospheric reservoir. Aerobic methanotrophs, unlike anaerobic methane oxidizing archaea,...

Exploring nitrifier denitrification in Nitrosomonas communis and Nitrosomonas europaea through physiology and proteomic analysis
DownloadSpring 2023
The current understanding of how ammonia oxidizing bacteria (AOB) produce the potent greenhouse gas nitrous oxide is incomplete and inaccurate since most studies are focused on the model organism for the group, Nitrosomonas europaea, which does not represent the physiological diversity of AOB....

Fall 2016
Ammonia oxidizers come from two different domains of life, the Archaea and Bacteria, and control a vital step in the global biogeochemical Nitrogen cycle; the conversion of ammonia to nitrite. They are abundant in a wide range of environments including marine and freshwaters, terrestrial soils,...

Methodologies in Mechanistic and Machine Learning Modelling of Nitrous Oxide Emissions from Wastewater Treatment Processes
DownloadFall 2024
Nitrous oxide (N2O), a potent greenhouse gas, significantly contributes to the carbon footprint of wastewater treatment plants (WWTPs), with a global warming potential 300 times that of CO2 and also notorious for its ozone-depleting effect. Modelling can be a valuable alternative to...

Nitrogen and Sulfur Fertilization Effects on Carbon Sequestration and Greenhouse Gas Emissions in S-deficient Soils
DownloadFall 2016
Depending on management practices, agricultural soils have the potential to be both a source and a sink of greenhouse gases (GHGs). Long-term fertilization and crop rotation management practices are considered to have an impact on carbon (C) sequestration and nitrous oxide (N2O) emissions. Sulfur...

Nitrous Oxide Emission Reduction in an Annual Cropping System as a function of Nitrification Inhibitors and Liquid Manure Injection Timings
DownloadFall 2016
Nitrous oxide (N2O) contributes to global warming and ozone depletion. Two-thirds of the global N2O emissions are derived from agricultural soils receiving manure or fertilizer applications. The goal of this study was to identify and develop management practices that can decrease N2O emissions...

Nitrous Oxide Emissions in Southern Alberta Croplands in response to Nitrogen Rates, Fertigation and Moisture
DownloadSpring 2018
Irrigated agriculture is an important source of global food supply due to its high production intensity; however, it is also a large user of water and nitrogen fertilizer, and therefore, a potential large contributor of N2O emissions. This study explores the viability of fertigation, a method of...

Fall 2018
This work contains investigations relevant for the study of catalytic chemical reactors using the detailed microkinetics approach, with the intent of improving the prediction of the product distribution. The study is comprised of two main topics. The first one consists of an investigation of...
