Does fire severity difference create divergent plant communities in black spruce-Kalmia forests of eastern Canada?
(2009-06-25)After fire, some conifer-ericaceous plant communities in Western Europe and eastern North America have demonstrated divergent succession from traditional conifer stand replacement to Ericaceae-dominated community states. ... -
Does mental illness stigma differ across disorders? An investigation of public stigma and attribution theory in social anxiety disorder, depression & schizophrenia
(2021)Individuals experiencing mental illness face numerous negative social, economic, and personal outcomes, partly due to the public stigma around mental illness. Attribution theory posits that stigma occurs when publicly ... -
Does mortality salience play a role in homophobia?
(2012-11-10)Mortality salience (MS) occurs when a person experiences greater access to thoughts of his/her own eventual death causing fear; it is said that worldview defence structures are activated in an attempt to alleviate this ... -
Does the presentation of neonatal abstinence syndrome symptoms differ among infants based on exposure substance?
(2014-01-22)INTRODUCTION: Neonatal abstinence syndrome (NAS) is one of the primary negative effects of substance use during pregnancy. Neonatal abstinence syndrome refers to a generalized disorder observed in infants experiencing ... -
Does this count for marks? : a mixed methods analysis of teacher opinion of counting a large-scale assessment toward class grades
(2012-11-10)The objective of this research was to gain insights on teacher opinions related to the practice of counting a portion of a large-scale educational assessment (LSA) for students' grades. [The author] anaylized the responses ... -
Dog sports : a mixed methods exploration of motivation in agility participation
(2015-08-05)Obesity and physical inactivity are on the rise amongst Canadians. Dog sports, agility in particular, may represent a form of physical activity that can help address the health issues that some of our population face. ... -
Dominance and competition: a giving-up density analysis of rank-based foraging decisions of small groups of confined bison (Bison bison)
(2023)Socially foraging animals such as bison (Bison bison) modify their foraging behaviour based on social status and food availability to maximize individual fitness. Winter feeding trials were performed on juvenile bison ... -
Drought effects on soil enzyme activity
(2021)Soil extracellular enzyme activity (EEA) is a strong predictor for soil health. EEA cycle nutrients within terrestrial systems, processing carbon, nitrogen, and phosphorous, while also mineralizing and stabilizing gas. ... -
Dual-modality image guided high intensity focused ultrasound device design for prostate cancer : a numerical study
(2010)In this study we established the feasibility of designing a multi-element high intensity focused ultrasound (HIFU) device for Magnetic Resonance and an ultrasound imaging-guided transrectal treatment of prostate cancer. ... -
Durability and mechanical properties of Portland cement concrete that utilizes crumb rubber as an alternative fine aggregat
(2018)This research project investigated in an intensive experimental program the influence of using crumb rubber in the mechanical properties and durability of Portland cement concrete mixtures. Crumb rubber is produced from ... -
DVS-capable ultra-low-power subthreshold CMOS temperature sensor / by Gregory Toombs.
(2010)There are many contemporary contexts in which a small, low-power-consumption temperature sensor is very valuable. Power, area, speed and temperature range factors are important constraints in modern VLSI design. As transistor ... -
Dynamic bandwidth allocation in CDMA-based passive optical networks
(2014-12-18)Fiber to the home (FTTH) technology is an attractive solution for providing high bandwidth from the Central Office (CO) to residences and small-and medium-sized businesses. The emergence of Internet Protocol-based communication ... -
Dynamic bandwidth allocation in WiMAX broadband networks
(2012-11-10)Wireless communication networks have experienced remarkable growth in recent years and are becoming attractive alternative to cable and DSL in providing last mile network access. Candidate wireless technologies should be ... -
