Study of two different tunable vibration absorbers : variable stiffness absorber and variable damping absorber
(2003)A structure or machine w ill vibrate at the frequency of excitation when excited by a harmonic force. Vibration of the structure can be suppressed using a vibration absorber by setting the absorber’s natural frequency ... -
Study of zonation at the Nanisivik Zn-Pb-Ag mine, Baffin Island, Canada
(1985)Zn-Pb-Ag mineralization at Nanisivik, northwest Baffin Island, is hosted by Proterozoic, laminated dolostone of the Society Cliffs Formation. Mineralization of the Main Orebody is highly variable in terms of texture and ... -
Study on the effects of therapist contact on progressive muscular relaxation training for mixed migraine and tension headaches
(1993)The effectiveness of home-based relaxation and therapist-contact relaxation treatment for headaches were evaluated in comparison to a waiting list control group. A group of 30 subjects diagnosed as suffering mixed ... -
Studying the properties of engineered wood products
(2023)Glulam and OSB are great building alternatives to typical materials in terms of their strength, aesthetics, and economical nature. North America mostly uses Spruce, Pine, and Fir (SPF) owing to their superior strength ... -
Sub-1 V, 4 nA CMOS voltage references with digitally-trimmable temperature coefficient
(2014-12-12)Voltage references are fundamental to mixed signal converters which are widely used in elec- tronics. Hence there are signicant advantages in having the voltage reference operate with less power while minimizing area ... -
Subject-generated internal imagery coupled with relaxation as a treatment for chronic pain
(1995)The chronic pain experience is a multifaceted phenomenon involving sensory, cognitive, affective, motivational and behavioral dimensions. There has been no single consistently successful method of pain control and ... -
Submerged anaerobic membrane bioreactors for Kraft evaporator condensate treatment : feasibility and membrane fouling studies
(2008)In this study, the primary goal was to develop better treatment technologies for energy recovery from Kraft evaporator condensate (EC) using thermophilic and mesophilic submerged anaerobic membrane bioreactors (SAnMBRs). ... -
Submerged anaerobic membrane bioreactors for wastewater treatment and membrane fouling characterization and control
(2012-11-10)This thesis focused on effects of transient conditions (pH shocks, temperature variation and temperature shocks) on the performance and membrane fouling characterization and control of submerged anaerobic membrane ... -
A Subspace of l2(X) without the approximation property
(2012-11-10)The aim of the thesis is to provide support to the following conjecture, which would provide an isomorphic characterization of a Hilbert space in terms of the approximation property: an infinite dimensional Banach space X ... -
Subspecies status of the western Yellow-billed Cuckoo (Cuculidae: Coccyzus americanus occidentalis) : using cytochrome b to elucidate the enigma
(2006)This study documents sequence variation in three mitochondrial DNA (mtDNA) genes in the Yellow-billed Cuckoo {Coccyzus americanus) to re-examine the subspecies status of the western population (C.a. occidentalis). ... -
Substance use motives and personality traits among a First Nation treatment-seeking population
(2022)Problematic substance use is one of the top disparities affecting Indigenous people. Among non-Indigenous people, specific personality traits and drinking motives are associated with problematic patterns of alcohol use. ... -
Substituent descriptors from the topology of the electron density
(2021)This work focuses on determining the suitability of functional group properties from the Quantum Theory of Atoms in Molecules (QTAIM) as descriptors for use in machine learning and linear regression analyses. These were ... -
Successful aging in Canadian seniors : implications for public health promotion and planning for an aging population
(2008)Rowe and Kahn (1987)proposed that successful aging (SA) is the balance of three components; a) absence of disease and disease-related disability, b) high functional capacity, and c) active engagement with life. In contrast, ... -
Suicide discourse in Canada : analysis and implications for prevention
(2005)According to the World Health Organization (WHO, 1999) someone in the world dies by suicide every forty seconds. The age group most likely to opt for suicide at this time is young adults, and among the 105 countries that ... -
Sulfo-functionalization of lignin and its impact on the stabilization of colloidal systems
(2021)Lignin macromolecules, derived from renewable biomass resources, have gained extensive interest during the past decade as a sustainable substitute for synthetic oil-based materials. The main goal of this dissertation was ... -
Sulfonation of kraft lignon to water soluble value added products
(2014-12-11)Kraft lignin is water insoluble and has limited end-use applications. The main objective of this MSc studies was to rend kraft lignin water soluble, and various value-added products including dispersants and flocculants. ... -
