Degenerate four wave mixing in biased semiconductor superlattices
(2001)Includes material on semiconductor Bloch equations, the Wannier-Stark ladder and Bloch oscillation theory. It also develops the equations of motion which allow calculation of the DFWM signal for biased semiconductor ... -
Demographic, reproductive, and psychosocial predictors of mood change in the postpartum period
(2009)The purpose of this study was to examine demographic, reproductive, and psychosocial predictors of mood change in the postpartum period. In a prospective design, 33 women completed either an online or paper and pencil ... -
Demonstration and evaluation of hemoglobin and hematocrit testing as support services in preparing elite swimmers for serious competition
(1982)These studies demonstrated and evaluated the usefulness of hemoglobin concentrations (Hb gm%) and hematocrit percentages (Hct %) in the preparation of elite swimmers for serious competition. Study 1 monitored Hb and Hct ... -
Density dependent extinction : phase II
(1993)In two separate experiments, an 8 rat 8 station operant arena was used to study resistance to extinction to test learning and optimal foraging theories of behaviour. The learning theory, called the generalized decrement ... -
Density, depth distribution and richness of emerging insects (Diptera: Chironomidae) before and after experimental watershed deforestation
(1999)The primary objective o f this study was to document changes in Chironomidae density, depth distribution, and taxon richness, associated with experimental upland and riparian deforestation of L42, a small boreal forest ... -
Density-dependent habitat selection alters fitness in a clonal hexapod
(2019)Density-dependent habitat selection shapes the distribution and abundance of organisms and thus informs our understanding of the eco-evolutionary process. When habitat choice is contingent on an individual’s expectation ... -
Depictions of race : self and other in Tolkien's and Jackson's Lord of the Rings / by Jonathan Epp.
(2008)The war between darkness and light depicted in J. R. R. Tolkien’s famous fantasy. The Lord of the Rings, is the subject of much debate and interpretation. At a first reading, Tolkien’s story can be mistaken as following ... -
Deploying an unmanned aerial vehicle (UAV) equipped with a multispectral sensor for detecting between differing levels of barley (H vulgare L.) fungal diseases in Northern Ontario
(2017)To date, no studies exist exploring the multispectral detection of fungal diseases in barley (H Vulgare L.) with UAV imagery. The purpose of this work was to determine if the spectral response (VI) of barley fungicide ... -
Depositional environments of the 3.0 Ga. Finlayson and Lumby Lake greenstone belts, Superior Province, Ontario, Canada
(1998)The Finlayson and Lumby Lake Greenstone BeHs are located approximately 200km west of Thunder Bay, Ontario, nom of Atikokan, Ontario. Within both the Finlayson Lake and Lumby Lake Grsenstom belts two distinct sequences ... -
Depositional processes operating on the paleoproterozoic gowganda ice margin
(2014-01-22)Glacial sedimentary rocks of the Huronian Supergroup crop out along the north shore of Lake Huron and were likely deposited on what is thought to have been a divergent continental margin (Fralick and Miall, 1981; 1989). ... -
Depression and anxiety in cancer patients seeking psychosocial therapy
(2002)The prevalence of mental disorders (particularly depression and anxiety) in a sample of Canadian cancer patients who were referred to a psychosocial oncology program was investigated. Thirty-one cancer patients filled ... -
Depression and cognitions of significant life events
(1987)The present study examined a number of relevant underlying cognitions of depression, within the context of learned helplessness theory, and more specifically, reformulated learned helplessness theory. Previous research ... -
Depression, quantity of social interaction, reciprocal self-disclosure, and perspective-taking in the elderly
(1985)The present research was designed to investigate the relationships among; a) depression, b) the quantity of social interaction and, c) the quality of social interaction in the elderly. Twenty-three residents aged 72 ... -
Depressive symptomatology and lifelong music experience: a cross-sectional study
Depression is a serious mental health disorder, with enormous costs to individuals and society. According to the 2012 Canadian Community Health Survey, approximately 1.9 million Canadians have reported a major depressive ... -
Design and control of a 10 DOF biped robot
(2009)Compared to wheeled robots, biped robots have their advantages. Biped robots have better mobility. Biped robots can walk in human environments, such as rough terrain and the place that contains obstacles, and can also climb ... -
Design and control of a 6 DOF biped robot
(2006)This thesis is composed of the following five parts: construction of a 6 Degrees of Freedom (DOF) biped robot, control system design, analysis of forward kinematics and inverse kinematics, walking pattern planning, and ... -
Design and Development of Dual Tuned 19F and 1H RF Birdcage Coils for Small Animal MRI at 3T
(2015)Conventional proton (1H) magnetic resonance imaging (MRI) is generally insensitive to the lung due to the low tissue density and other complicating factors. On the other hand, inhaled inert fluorinated gas MRI is a ... -
Design and electrochemical study of Pd-based nanostructures for hydrogen economy
(2017)Hydrogen storage remains one of the most challenging prerequisites to overcome toward the realization of a hydrogen based economy. The use of hydrogen as an energy carrier for fuel cell applications has been limited by the ... -
