breastfeeding and postpartum depression: assessing the influence of breastfeeding intention and other risk factors
(2015)risk and protective factors for postpartum depression have been extensively studied, and more recently an association between breastfeeding and maternal mood has been reported. the purpose of the present study was to clarify ... -
nonlinear adaptive control for robust wide speed range operation of ipmsm drives
(2015)various applications, including robotics, spindle drives, machine tools, etc. rely on accurate, reliable controllers to deliver the required drive performance. with recent advances in magnetic materials and semiconductor ... -
the influence of depression symptoms and antidepressant medications on cognition and driving performance
(2015)research that has examined the influence of depression symptoms and antidepressant medications on driving performance has revealed inconclusive findings (brunnauer, laux, geiger, soyka, & moller, 2006; bulmash et al., ... -
performance investigation of h control and port controlled hamilton with dissipation based nonlinear control for ipmsm drives
(2018-03-13)within the field of electrical drive systems, there has been increasing popularity in the use of permanent magnetic synchronous machines as an execution unit, and the cooperation with high performance control strategy. ... -
simultaneous vibration suppression and energy harvesting with a non-traditional vibration absorber
(2017)the dynamic vibration absorber, or tuned mass damper, has been one of the most commonly used passive vibration control devices over the past hundred years. with an optimally designed vibration absorber, significant vibration ... -
effect of periphytic escherichia coli and lake water bacterial population on the biofilm establishment of a shiga toxin producing escherichia coli o157:h7 strain
(2015)biofilm studies escherichia coli (e. coli) have typically focused on 0157:h7 in defined, laboratory medium. while there is value in such studies, they offer little in the way of explaining the behaviour and interactions ... -
validation of discrete ordinate radiation model for application in uv air disinfection modeling
(2014)this study investigated one of the most important aspect of ultra-violet (uv) air disinfection modeling which is radiation modeling. radiation modeling is a topic of interest in the domain of uv air disinfection research. ... -
a novel approach to reaction modeling for photocatalytic oxidation processes
(2014)volatile organic compounds (vocs) are one of the major concerns for indoor air quality. a new method for treating vocs in the air is through an advance oxidation process (aop) known as photocatalytic oxidation (pco). ... -
eutrophication in northwestern ontario? the unique case study of cloud lake
(2017)this thesis investigates freshwater lake classification in northwestern ontario, canada. the research is based on a case study of cloud lake, 40km south of thunder bay ontario, canada. complaints of decreasing water quality ... -
attitude control of a quadrotor uav: experimental results
(2017)the quadrotor is a type of unmanned aerial vehicles (uavs) which is gaining popularity over the past few years for its potential applications. quadrotor uavs are used, for instance, for surveillance, search and rescue ... -
fiber laser system for the detection of trace gas
(2017)the research presented in this thesis is on the development of a trace gas detection system based on intracavity absorption spectroscopy (icas). the developed system was capable of detecting nitrous oxide (n2o) and acetylene ... -
conversion of crude glycerol from the biodiesel industry to value added products
(2017)crude glycerol is a major by-product of the biodiesel industries. for every 100 kg of biodiesel produced, approximately 10 kg of the byproduct glycerol is generated. with the large increase in biodiesel production, there ... -
hydrogen sulfide modulates gluconeogenesis and mitochondrial biogenesis in mouse primary hepatocytes
(2016)among many endogenous substances that regulate hepatic energy production is the gasotransmitter hydrogen sulfide (h2s). in the liver, h2s production is largely catalyzed by cystathionine γ-lyase (cse) and, to a lesser ... -
modelling the molecular mechanisms of biocompatibility of artifical materials
(2015)one of the most common reasons for implant failure is immune rejection. implant rejection leads to additional surgical intervention and, ultimately, increases health cost as well as recovery time. within a few hours after ... -
understanding patterns of pleasure craft tourism in the canadian arctic and implications for safety management
(2015)this study establishes an understanding of pleasure craft tourism patterns in the canadian arctic from 1990-2013 with a focus on the implications for safety. two specific objectives were fulfilled: 1. to develop an ... -
the relationship of patterns of creativity and machiavellianism to leadership, self-actualization, authoritarianism, and alienation
(1979)the purpose of this study was to investigate patterns of creativity and machiavellianism and how they relate to leadership, self-actualization, authoritarianism, and alienation. creativity and machiavellianism served as ... -
synthesis and electrochemical study of ptlr and ptru nanomaterials
(2015)the rapidly growing need for clean energy on a global scale has led to the emergence of new fields of scientific research to facilitate the discovery and development of novel energy sources, such as fuel cells, which ... -
predicting mixing trends in mine-receiving waters using water quality modeling
(2016)complete mixing of the water column of lakes is important to ensure that nutrients and dissolved oxygen are replenished and equalized throughout the lake. this ensures that organisms within the lake at all trophic levels ... -
biogenic lead levels in human skeletal remains from the cemetery of the british royal navy hospital (1793-1822ce) at english harbour, antigua west indies
(2015)though lead has been known to be a cause of human poisoning since ancient times, it was a widely used metal. the relationship between ancestry or age and lead exposure in the colonial period of antigua, west indies was ... -
