Diatoms as an indicator of pharmaceutical contamination in a freshwater system
(2018)Historically, microalgae have been used as bio-indicators of aquatic health and this can be seen in several studies across the world. Often at the bottom of the food chain, microalgae constitute the primary producer of ... -
Dielectric and infrared studies of radio frequency processes in some alcohols
(1988)In this thesis, the results of dielectric studies on a number of aliphatic alcohol molecules with variable chain lengths are presented. This investigation was complemented by infrared and viscosity measurements. Dielectric ... -
Dielectric relaxation and infrared studies of hydrogen bonding
(1985)Dielectric relaxation and infrared study of a number of associating (H-bonding) compounds in glassy media, mainly polystyrene, have been carried out. The dielectric measurements by a General Radio 1621 Precision ... -
Dielectric relaxation studies of some diaryl molecules in polystyrene matrices
(1978)Dielectric relaxation studies of a number of diaryl molecules dispersed in atactic polystyrene and in some cases as solid discs have been carried out. Preparation of the polystyrene matrices and the solid disks, and the ... -
Dielectric studies of molecular and intramolecular motions in polystryrene matrices
(1977)Dielectric absorption studies of a variety of polar solutes containing rotatable groups and of some analogous rigid molecules dispersed in atactic polystyrene have been carried out. Preparation of the solutions as solid ... -
Dielectric studies of molecular motions in some solids
(1982)Dielectric absorption of a number of nonpolar, weakly polar and fairly polar molecules in the pure solid state are studied. Measurements of these solids using either a General Radio 1621 Precision Capacitance Measurement ... -
Dielectric studies of rigid and flexible molecules in various media
(1984)This thesis investigates mainly the molecular and intramolecular relaxation processes of some aromatic and aliphatic molecules containing rotatable polar groups and some analogous rigid molecules dispersed in (a) ... -
Dietary restraint : the role of causal attributions
(1995)Previous studies have indicated that restrained and unrestrained eaters exhibit dififerent eating patterns in response to preloading or no preloading. After a preload, restrained eaters tend to exhibit counterregulatory ... -
Dietary restraint and stress-induced alterations in eating: Exploring the role of heart rate variability as a proxy for self-regulation, attentional bias, and perceived safety
(2021)Restraint theory posits that the capacity to successfully diet is cognitively demanding, requiring exertion of cognitive control over eating. Demands that deplete this limited inner resource (e.g., stress) can thus lead ... -
Dieting practices, influences, beliefs and self-concept of female high school students
(1991)There has been a recent explosion of interest in anorexia nervosa and bulimia nervosa. There are many social influences which are thought to encourage women to strive for unrealistic thinness. The suggestion that with early ... -
Differences between elderly and young drivers : driving vigilance in two tasks
(2007)According to statistics for 2003, 9 in 100,000 people in Canada died from driving accidents. A high percentage (30-40%) of these took place due to sleepiness on monotonous road conditions. Therefore, driver vigilance must ... -
Differences between the Francophone and Anglophone ethno-linguistic groups in the home care setting of Ontario
(2009)Although Francophones in Ontario represent the largest population of French-Canadians outside Quebec, little is known about this population, and especially about the older members of this ethno-linguistic group. The scarce ... -
Differences in density measures between TreeAzin® injected and non-injected ash wood
(2021)This undergraduate thesis explores an observation made by the City of Thunder Bay’s urban forestry department staff of TreeAzin injected Green Ash tree’s limbs and branches failing shortly after being injected. The ... -
Differences in dung beetle (Coleoptera: Scarabaeinae) assemblages in different habitat types and habitat patches within the Verde Sumaco forest, Ecuador
(2019)Scarabaeinae, the dung-eating beetle subfamily, comprises keystone species that perform a host of ecological functions. They are easily surveyed and respond to habitat change, making them suitable indicators of effects of ... -
Differences in extrinsic tree quality and value of fibre production following alternative vegetation management treatments in Northwestern Ontario
(2011)We examined differences in stem quality, and volume and value of fibre produced by planted white spruce 16 years after vegetation management treatments in northwestern Ontario. Forest Vegetation Simulator (FVSOntario) was ... -
Different approaches to teaching English language learners in Ontario private elementary schools
(2018)There has been growing interest in the methods and programs that have been implemented in Ontario for English language learners in recent years. However, there is a dearth of research that focuses specifically on English ... -
Differentiable and rough norms
(1970)The principal question discussed in this dissertation is the problem of characterizing the existence of admissible Frechet differentiable norms on Banach spaces. In the first chapter the basic concepts of normed linear ... -
Differential item and test functioning of the Brief Child and Family Phone Interview in First Nations and non-First Nations children and adolescents / by Dana Bova.
(2006)In 2001 the Ontario Ministry of Social Services mandated that all Ontario funded providers of children mental health services utilize the BCFPI (Brief Child and Family Phone Interview) which assesses emotional and behavioural ... -
Differential response of two common human papillomavirus 16 E6 variants to small interfering RNA
(2014-01-22)High-risk human papillomaviruses (HPVs), such as HPV16, are implicated in causing virtually all cases of cervical cancer. Molecular therapies capable of targeting HPV16 E6 oncoprotein expression can selectively eliminate ...
