Abstract: <p>Phenolic compounds are used in industry, such as agriculture and biotechnology, and inevitably end up in our environment. These compounds may serve as a phenolic precursor to produce raw materials for a wide range of applications. Chemical oxidation has been the common synthetic pathway to oxidize phenols and related compounds. However, traditional chemical approaches suffer from use of… more Full Text: Electrochemical versus Chemical Oxidation of Bulky Phenols: 2,6-diphenylphenol and 2,2dihydroxybiphenol A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty …

Abstract: <p>Fungal pathogens adapt to environmental changes faster than their hosts, due in part to their adaptive mechanisms exhibited in response to stress. Ustilago maydis was used to investigate potential natural antisense transcript (NAT) RNA-mediated mechanisms that enhance fungal adaptation to stress. Of the 349 NATs conserved amongst U. maydis and two related smut fungi, five NATs were… more Full Text: Exploring the Role of Natural Antisense Transcripts in the Stress Response of Ustilago maydis A thesis submitted to the Committee of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science in the faculty of Arts and …

Abstract: <p>In Ontario, the dominant cash crop rotations consist of soybean (SB), which is a leguminous crop grown in rotation with maize (MZ) and winter wheat (WW). In addition to these crops, some farmers integrate cover crops (CC) into crop rotation, especially during the fallow period and winter seasons, to reduce nitrogen (N) losses via nitrate (NO3-) leaching and emission of N2 and the… more Full Text: i IMPACTS OF COVER CROPS ON SOIL HEALTH, SOIL NITROGEN DYNAMICS, AND CYTOKININ PROFILES A Thesis Submitted to the Committee on Graduate Studies In Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and …

Abstract: <p>Nutrient losses from forest soils caused by decades of acid deposition and intensive tree harvesting have affected tree growth and forest health in North America and Europe. Non-industrial wood ash (NIWA), a substance rich in macronutrients, may be a potential remediation strategy to return lost nutrients to forest. However, the chemical composition of NIWA and its effects on soil and… more Full Text: Non-industrial wood ash chemistry and its biogeochemical effects on sugar maple (Acer saccharum, Marsh.) in three central Ontario sugar-bushes A Thesis Submitted to the Committee on the Graduate Studies in Partial Fulfillment of the Requirements for the …

Abstract: <p>The accelerated recovery of base-poor soils from the legacy effects of acidic deposition may be possible by applying industrial wood ash as a soil amendment. Wood ash may be an effective soil amendment due to its high alkalinity and concentrations of several essential nutrients, such as calcium, magnesium, potassium, and phosphorus, that are retained after the volatilization of the… more Full Text: Short-term biogeochemical response of hardwood forest soils to wood ash additions in central Ontario A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of …

Abstract: <p>Social scientists have debated whether religious involvement is associated with differences in deviant behaviours for over a century. Religious practices and beliefs are often associated with less deviant behaviours in young adults, such as less frequent drug use and law-breaking. Empirical results on these associations, though, have been mixed, possibly due to heterogenous measures.… more Full Text: THOU GOD SEEST ME: AN INVESTIGATION INTO THE ROLE OF RELIGION AND SPIRITUALITY IN DEVIANT BEHAVIOURS IN YOUTH A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the …
