The Reproductive Ecology Of Convict Cichlids In Costa Rica, Brian Douglas Wisenden
The Reproductive Ecology Of Convict Cichlids In Costa Rica, Brian Douglas Wisenden
Digitized Theses
Convict cichlids (Cichlasoma nigrofasciatum) form monogamous pair bonds and have cooperative biparental care of their eggs, larvae and fry for up to six weeks. This fish is widely used in laboratory studies as a model of biparental care. However, very little is known of its habits in its natural habitat. I studied four natural populations of convict cichlids, in 'pool' and 'stream' habitat, in Costa Rica during the long dry season, December to June in 1990 and 1991. The number of pairs guarding broods increased from December to a peak in mid-March, then rapidly declined. Twenty-eight percent of 175 males …
Synthetic Applications Of The Photochemical Cycloaddition Reactions Of N-Acylindoles And Conformational Studies Of The Cycloadducts, Boke Zhang
Digitized Theses
The ability of a series of nitrogen-substituents to activate the cycloaddition photochemistry of indoles has been examined; the N-substituents were chosen in order to enable their removal following cycloaddition under mild neutral, acidic or basic conditions. N-substituted indoles, 17, 12 and 104c-g, were prepared in which the N-substituent is COPh, CO{dollar}\sb2{dollar}Et, CO{dollar}\sb2{dollar}CH{dollar}\sb2{dollar}CH{dollar}\sb2{dollar}SiMe{dollar}\sb3{dollar}, CO{dollar}\sb2{dollar}CH{dollar}\sb2{dollar}CH{dollar}\sb2{dollar}CN, CO{dollar}\sb2{dollar}Bu{dollar}\sp{lcub}\rm t{rcub}{dollar}, CO{dollar}\sb2{dollar}Ph, and CO{dollar}\sb2{dollar}CH{dollar}\sb2{dollar}Ph, respectively.;The silylethoxycarbonyl group of photoadducts derived from 104c can be removed by treatment of the adduct with fluoride ion in dichloromethane, the tert-butyloxycarbonyl group of adducts derived from 104e by treatment with trifluoroacetic acid at room temperature; the benzyloxycarbonyl group of adducts …
Effects Of Wave Reflections In Pulsatile Flow Through Vascular Networks, Bo Duan
Effects Of Wave Reflections In Pulsatile Flow Through Vascular Networks, Bo Duan
Digitized Theses
The subject of this thesis is wave propagation in fluid-filled distensible tubes, with emphasis on the effects of wave reflections in pulsatile flow through vascular networks.;A computing scheme for wave propagation in vascular trees with branching junctions is developed. Due to the large number of junctions usually present in vascular trees, only one-dimensional theory is practical. The propagating waves consist of transmitted and reflected components. A generalized model of branching trees is considered. An iterative formula for pressure in each vessel is derived, which leads to explicit expressions for pressure and flow distributions in the entire tree. Pressure distributions in …

The Dunn, Hiawatha, Stambaugh, and Fortune Formations are variably pyritic and sideritic shale, chert, siltstone, and greywacke. The Paint River Group is …
Segregation And Oxidation Studies Of Aluminum-Lithium And Aluminum-Magnesium Alloys, Frank Joseph Esposto
Segregation And Oxidation Studies Of Aluminum-Lithium And Aluminum-Magnesium Alloys, Frank Joseph Esposto
Digitized Theses
Auger electron spectroscopy, work function measurements, low energy electron diffraction, nuclear reaction analysis, dynamic/static secondary ion mass spectrometry, thermal desorption spectroscopy, and synchrotron radiation-photoemission spectroscopy have been used to investigate the segregation and oxidation of (111) oriented Al-6.5(at.%)Li and (110) oriented Al-1.45(at%)Mg single crystal binary alloys. The resulting Li and Mg equilibrium surface concentrations are found to be 0.16 and 0.47 respectively. For both alloys, the increase in surface concentration was associated with a decrease in {dollar}\Delta\phi{dollar}. {dollar}\surd 3\rm x\surd 3R30\sp\circ{dollar} and c(2x2) superlattices were observed at the equilibrium surface concentrations for the Al-Li and Al-Mg alloys respectively. This is …
Computed Tomography Scanner For Dynamic Vascular Imaging In Vitro, Maria Drangova
Computed Tomography Scanner For Dynamic Vascular Imaging In Vitro, Maria Drangova
Digitized Theses
A dynamic computed-tomography (CT) scanner has been developed for imaging objects undergoing periodic motion. The scanner has high spatial resolution and sufficiently high temporal resolution to produce quantitative tomographic images of objects, such as excised arterial samples perfused under physiological pressure conditions.;The dynamic CT scanner is comprised of a modified x-ray image intensifier (XRII) coupled to a 1024-element linear photo-diode-array detector. The XRII was modified to allow continuous electro-optical magnification of the field-of-view, thereby increasing the system's limiting resolution. High-resolution gated projection radiographs of a single slice are acquired at the rate of 60 Hz, as the object undergoes periodic …
Differentials And Determinants Of Fertility Behaviour In Bolivia, David Ernesto Vidal-Zeballos
Differentials And Determinants Of Fertility Behaviour In Bolivia, David Ernesto Vidal-Zeballos
Digitized Theses
This thesis examines differentials and determinants of fertility behaviour for the Bolivian population, focusing on the biological, behavioural, economic, social and cultural factors that directly and indirectly affect reproductive behaviour among the three ecological strata (Highlands, Valleys and Lowlands) and two spatial contexts (Urban and Rural). Moreover, the measurement, description and explanation of these factors at the individual and aggregated levels, and the link between the two levels of analysis has been attempted to examine the interrelationship among proximate determinants, microeconomic variables--cost regulation and motivational cost--modernization and cultural variables, and to understand the differentials in fertility. To do this study, …
The Dialogical Keats: Studies In A Bakhtinian Approach To Keats' Narrative Poems, Michael J. Sider
The Dialogical Keats: Studies In A Bakhtinian Approach To Keats' Narrative Poems, Michael J. Sider
Digitized Theses
A tradition of criticism in Keats studies has constructed a view of the poet as a writer who is entirely disengaged from history and of his poems as completely finished products, self-contained and ahistorical. This view of the poet and his poems dominates our present understanding of Keats. This dissertation, "The dialogical Keats: Studies in a Bakhtinian approach to Keats' narrative poems," is an attempt to develop a reading of Keats' poetry which uncovers those qualities in the poems that have been denied by the tradition of Keats criticism. Bakhtin's view of language as shared social territory provides a tool …
Chemistry Of Binuclear And Cluster Complexes Of Ruthenium, Cobalt And Nickel, Hameed A. Mirza
Chemistry Of Binuclear And Cluster Complexes Of Ruthenium, Cobalt And Nickel, Hameed A. Mirza
Digitized Theses
The work described in this thesis is mainly focused on the synthesis, characterization and chemical reactivity of dinuclear and trinuclear phosphine substituted carbonyl complexes of Ru, Co and Ni. The thesis can be broadly classified into three sections. The first section comprising chapters 2 and 3, deals with the chemistry of dinuclear and trinuclear ruthenium complexes with dppm, bis(diphenylphosphino)methane, bridging ligands. The reaction mixture RuCl{dollar}\sb3{dollar}/dppm/NaBH{dollar}\sb4{dollar}/CO yielded mainly trans- (RuCl{dollar}\sb2{dollar}(dppm){dollar}\sb2{dollar}). However, when silver acetate was added to the reaction mixture prior to the reduction with NaBH{dollar}\sb4{dollar}, a high yield synthesis of (Ru{dollar}\sb2{dollar}({dollar}\mu{dollar}-CO)(CO){dollar}\sb4{dollar}({dollar}\mu{dollar}-dppm){dollar}\sb2{dollar}) was achieved. In addition, (RuH(CO)(dppm){dollar}\sb2{dollar}) {dollar}\sp+{dollar} and the electron …
Hydrodynamic And Electrohydrodynamic Instability Of Shear Flows And The Numerical Simulation Of Viscous Droplets, Kenzu Abdella
Hydrodynamic And Electrohydrodynamic Instability Of Shear Flows And The Numerical Simulation Of Viscous Droplets, Kenzu Abdella
Digitized Theses
In this thesis, we investigate three fluid dynamic problems involving various physical mechanisms which exhibit interfacial instability. These problems have wide ranging industrial, scientific and engineering applications.;In the first problem, we investigate the linear stability of the unbounded Couette flow of two fluids separated by a plane interface. The exact dispersion relation is solved asymptotically and numerically to analyze the effects of the four stability parameters of the flow; the ratio of the viscosities, the ratio of the density, the surface tension and gravity. While our results confirm most of the earlier reported theories involving shear flows of fluids of …
Ground Motion Spatial Incoherence, Its Modelling And Effects On Long Gravity Dams, Osman Mohamed Ramadan
Ground Motion Spatial Incoherence, Its Modelling And Effects On Long Gravity Dams, Osman Mohamed Ramadan
Digitized Theses
Seismic design of concrete gravity dams is usually based on a two-dimensional analysis of one monolith, or slice. This analysis provides the basic information but neglects the interaction between adjacent dam monoliths and assumes uniformity of dam section, foundation properties and ground motions along the dam longitudinal axis. While the seismic response of gravity dams has been investigated in considerable detail, the effects of ground motion spatial incoherence on dam response have not been investigated to any great detail.;In this study, dam response to spatially variable seismic excitations is theoretically investigated. Deterministic and random representations of the space-time random field …
Stratigraphy And Geochemistry Of Neoproterozoic Iron Formation, South Australia, Kathryn Louise Neale
Stratigraphy And Geochemistry Of Neoproterozoic Iron Formation, South Australia, Kathryn Louise Neale
Digitized Theses
In the southern portion of the Adelaide geosyncline, the Neoproterozoic Yudnamutana Subgroup unconformably overlies older Neoproterozoic sedimentary rocks of the Adelaidean succession. The Braemar and Holowilena iron formations occur locally in the glacigenic Yudnamutana Subgroup at the transitional contact between the basal Pualco Tillite and overlying Benda Siltstone formations, or stratigraphic equivalents elsewhere.;Magnetite and/or hematite and absence of chert typify these iron formations which are associated with diamictite, subarkosic wacke, siltstone and minor carbonate. Diamictites are typically unstratified and have iron-poor ({dollar}{dollar}30 wt.% Fe{dollar}\sb2{dollar}O{dollar}\sb3{dollar}) matrices. The former commonly occur below the iron formation-bearing intervals whereas the latter are intercalated with …
A Behavioural Genetic Analysis Of Personality, Personality Disorder, The Environment, And The Search For Sources Of Nonshared Environmental Influences, Kerry Leslie Jang
A Behavioural Genetic Analysis Of Personality, Personality Disorder, The Environment, And The Search For Sources Of Nonshared Environmental Influences, Kerry Leslie Jang
Digitized Theses
A behaviour genetic analysis of personality, liability to personality disorder, and the general environment of siblings was conducted using a classic twin study design. A sample of 138 same-sex young adult twin pairs (89 monozygotic pairs, 49 dizygotic pairs) was used to estimate trait variance attributable to direct gene action (h{dollar}\sp2\sb{lcub}\rm A{rcub}{dollar}), shared environmental experiences (c{dollar}\sp2{dollar}), and nonshared environmental experiences (e{dollar}\sp2{dollar}). Paralleling previously published results, model-fitting heritability analyses of the Personality Research Form (PRF; Jackson, 1986), and the Minnesota Multiphasic Personality Inventory, (MMPI, Hathaway & McKinley, 1983) showed that additive genetic and nonshared environmental factors could satisfactorily account for the …
Decay Of The Triplet State In A Porphyrin Quinone Molecule, David Donald Fraser
Decay Of The Triplet State In A Porphyrin Quinone Molecule, David Donald Fraser
Digitized Theses
Workers in this and many other labs have been studying photoinduced electron transfer seeking to understand the photochemical processes in photosynthesis. Closely related processes also constitute the basis of some photosensitive tissue diseases and of a wide variety of industrial applications. To study the photophysics unhindered by diffusion, a molecule composed of a freebase porphyrin covalently linked to a p-benzoquinone by an amide linkage was used.;A nanosecond laser flash photolysis apparatus permitted the observation of the porphyrin triplet state decay, with the quinone fully reduced or with it fully oxidized to allow enhanced quenching of the porphyrin triplet via electron …
Ventilatory Response To Carbon Dioxide Stimuli In Aged Humans, Marc Jean Poulin
Ventilatory Response To Carbon Dioxide Stimuli In Aged Humans, Marc Jean Poulin
Digitized Theses
This thesis examined age-related changes in the ventilatory response to exercise and in the ventilatory response to inhaled carbon dioxide (CO{dollar}\sb2{dollar}) at rest. Specifically, the purposes were to: (1) examine the ventilatory response to CO{dollar}\sb2{dollar} production (VCO{dollar}\sb2{dollar}) during graded exercise below the ventilation threshold (T{dollar}\sb{lcub}\rm \.VE{rcub}{dollar}) in men and women aged 55 to 86 yrs, (2) determine the ventilatory response to CO{dollar}\sb2{dollar} at rest and evaluate the CO{dollar}\sb2{dollar} sensitivity of the central and peripheral chemoreceptors in young (YS, n = 7, 28.3 yrs) and old (OS, n = 11, 76.1 yrs) humans, and (3) determine the temporal parameters of the …
Behavioral, Electrophysiological, And Neuroanatomical Plasticity In The Rat, As A Result Of Complex Environment Housing, Eric Lynn Hargreaves
Behavioral, Electrophysiological, And Neuroanatomical Plasticity In The Rat, As A Result Of Complex Environment Housing, Eric Lynn Hargreaves
Digitized Theses
Long-term potentiation (LTP) is an electrophysiological phenomenon of neuroplasticity, whereby synaptic transmission of specific brain pathways become enhanced, or potentiated, after the delivery of a series of brief, high-frequency electrical trains. The increase in synaptic efficacy is of substantial duration, and therefore LTP has been likened to the theoretical reverberatory circuit that lead to permanent memory traces, as originally hypothesized by Hebb (1949). To further examine the direct relations between LTP and learning this thesis focused on the paradigm of complex environments, which have been shown to enhance learning, neocortical thickness, and hippocampal evoked potentials. It was decided to examine …
Isolation And Characterization Of A Genetic Locus Involved In Growth And Pathogenicity On Tomato Plants By Pseudomonas Syringae Pv Tomato, Dennis Paul Jackson
Isolation And Characterization Of A Genetic Locus Involved In Growth And Pathogenicity On Tomato Plants By Pseudomonas Syringae Pv Tomato, Dennis Paul Jackson
Digitized Theses
Pseudomonas syringae pv. tomato is the causal agent of bacterial speck on tomato. An essential feature of this organism, in the pathogenic process, is its ability to enter the intercellular spaces of its host and use the available plant substrates for growth. Tomato leaves contain quantities of carbon energy in the form of carboxylates. A Tn5 mutant, DC3481, cannot utilize carboxylates as a source of carbon energy for growth (CA{dollar}\sp-{dollar}) and is nonpathogenic (Path{dollar}\sp-{dollar}) on tomato. The focus of this thesis was to utilize DC3481 to isolate and characterize P. syringae pv. tomato DNA sequences involved with growth and pathogenicity …
A Characterization Of The Fast Pyrolysis Of Cellulose And Wood Biomass, Robert George Graham
A Characterization Of The Fast Pyrolysis Of Cellulose And Wood Biomass, Robert George Graham
Digitized Theses
The science of biomass fast pyrolysis is relatively young and incomplete. To date, there has been no systematic attempt to define fast pyrolysis in terms of chemistry, product distribution, kinetics, heat transfer requirements, and requisite process conditions. Neither has there been any experimental work which tracks the reaction progress as a function of both temperature and residence time. Furthermore, the literature provides a fragmented and often contradictory view of the nature of fast pyrolysis.;This thesis provides a coherent picture of the fast pyrolysis of cellulose and wood via an extensive literature review and systematic research. The literature review is an …
Dynamics Of Morbidity And Mortality In Africa And Implications For Health Care Planning, Sulaiman Maladoh Bah
Dynamics Of Morbidity And Mortality In Africa And Implications For Health Care Planning, Sulaiman Maladoh Bah
Digitized Theses
The dissertation aims to tie together the empirical, theoretical and policy oriented aspects dealing with the dynamics of morbidity and mortality in Africa. On the theoretical aspect, scholars are arguing that the epidemiologic transition theory which provided the framework for understanding African mortality in the past, is actually part of a broader health transition theory which also includes a health care transition. In this theory, the overemphasis on biomedical interventions is down-played. To understand African mortality, it is argued, we have to consider the social and cultural determinants. Also we have to consider morbidity and its relationship to mortality. This …
Dynamics Of The Envelopes Of Be Stars In The Equatorial Plane, Haiqi Chen
Dynamics Of The Envelopes Of Be Stars In The Equatorial Plane, Haiqi Chen
Digitized Theses
In this thesis, I shall investigate the dynamics of the envelopes of Be stars in the equatorial plane. Currently there is no general agreement as to what are the most important forces controlling the dynamics in and near the equatorial plane. I expect that my research will yield a significant improvement in the knowledge of the forces which are most important in controlling the dynamics of the circumstellar matter, and thus lead to a major advance in the understanding of Be stars. Recently, observations of the continuous energy distribution of several Be stars from infrared to radio wavelengths have been …
Brainstem Control Of Three-Dimensional Eye Movements, J Douglas Crawford
Brainstem Control Of Three-Dimensional Eye Movements, J Douglas Crawford
Digitized Theses
This thesis examines the neural mechanisms that generate torsional and vertical eye movements, and how they handle the kinematics of three-dimensional rotations. Three-dimensional eye rotations were recorded in alert monkeys, and the midbrain was studied using single unit recording, electrical microstimulation, and pharmacological inactivation.;The direction of VOR slow phases was usually opposite to that of head rotation, as required for optimal visual stabilization. However, direction errors sometimes occurred because of low gain about a head-fixed torsional axis. This axis was orthogonal to Listing's plane of saccadic eye positions, which suggests that saccades and the VOR share the same coordinate system. …
The Divided Text: Intertextual Ambivalence In Timothy Findley's Novels, Anne Elizabeth Bailey
The Divided Text: Intertextual Ambivalence In Timothy Findley's Novels, Anne Elizabeth Bailey
Digitized Theses
This thesis examines the ambiguous function of intertexts within Timothy Findley's novels. His fiction is in constant dialogue with other literary texts and conventions as well as numerous social, economic, and political discourses. This intertextual dialogue politicizes Findley's work because the re-presentation of intertexts often subverts and challenges ideological biases, revealing sexist, racist, and totalitarian features. However, the repetition of intertexts not only implies difference but also similarity, a paradox which creates ambiguity within Findley's novels. I propose that this ambivalence is evident in both the form and content of Findley's work, arguing that the relationship between his own texts …
The Effect Of Buyer-Seller Relationships On The Buyer's Evaluation And Choice, David William Large
The Effect Of Buyer-Seller Relationships On The Buyer's Evaluation And Choice, David William Large
Digitized Theses
Sellers of technology-based capital equipment are often required to participate in a competitive bidding process prior to the buyer's final evaluation and choice. Factors such as the competing sellers' relative prices and relative functional benefits are certainly important to the buyer. However, the relative quality of the competing sellers' buyer-seller (B-S) relationships, both before and during the bidding process, may also play an important role. Therefore, the management problem addressed by this dissertation, stated from the seller's perspective, is how to manage B-S relationships to favourably affect the buyer's choice in competitive bid situations.;A research model comprising eight constructs and …
Meaning And Matricide: Reading Woolf Via Kristeva, Miglena I. Nikolchina
Meaning And Matricide: Reading Woolf Via Kristeva, Miglena I. Nikolchina
Digitized Theses
The thesis examines the psychoanalytic myth of matricide in its relevance for a feminist understanding of literary history. The first half of the dissertation explores the problem of matricide in the terms offered by Kristeva's theory. My study emphasizes the larger context of Kristeva's work which is not confined to Freud and Lacan only; the effects of its cultural substratum involving such diverse traits as Byzantine iconograpy, East Orthodox dogma, and Bulgarian language and folklore; and the implications of its form as a "polylogue"--i.e. a transmutation of Bakhtin's polyphonic novel into a theory conscious of its fictional and semiotic dimensions.;In …
Suburban Land Constraints And Intraurban Income Distribution, Timothy J. Bailey
Suburban Land Constraints And Intraurban Income Distribution, Timothy J. Bailey
Digitized Theses
This dissertation examines the effect of space restrictions on the intraurban distribution of socioeconomic groups. It proposes that the centripetal income shifts evident in North American cities with suburban containment can be explained in part within the context of traditional neoclassical theory. A model is introduced to predict the residential location pattern in a metropolitan center when suburban land consumption constraints and a polycentric urban form are incorporated into the Alonso budget equation (Alonso, 1964). In this model two things happen to higher socioeconomic groups with a fixing of the size of new lots; the accessibility variable rises in relative …
Essays On Recursive Nonparametric Kernel Estimation Of Regression, Miang Hong Ngerng
Essays On Recursive Nonparametric Kernel Estimation Of Regression, Miang Hong Ngerng
Digitized Theses
In the practice of economics it is common that the data are observed not as a sample of fixed size, but rather as an ongoing sequence of a time series. It could be computationally advantageous if the estimate of the unknown function could be updated for each newly arriving data point. On some occasions, there is also a need to update the existing estimate with the newly realized observations. Kalman filter and Bayesian estimation are the commonly encountered techniques to handle these problems in the paradigm of linear parametric estimation. However, few procedures are available for nonlinear models, especially in …
A Reassessment Of Locke's Theory Of Cognition Of The External World, Thomas Heyd
A Reassessment Of Locke's Theory Of Cognition Of The External World, Thomas Heyd
Digitized Theses
Locke's Essay concerning Human Understanding has generally been read as primarily concerned with epistemology. In particular, it has been claimed that the Essay attempts to defeat epistemological skepticism, but fails in this enterprise because of the veiling character of Locke's ideas. By way of reexamination of the texts in question I show that epistemological skepticism is not the topic of the Essay, and that there is not sufficient reason to claim that Locke's account of knowledge leads to epistemological skepticism. I argue, moreover, that the motivating topic of the Essay is moral skepticism, and I explain the central role of …
Occupational Exposure To Styrene: Contribution To Hearing Loss, Andrea M. Sass-Kortsak
Occupational Exposure To Styrene: Contribution To Hearing Loss, Andrea M. Sass-Kortsak
Digitized Theses
Prolonged significant noise exposures are well known to result in permanent hearing loss. However, little is known of the contribution of industrial chemical exposures to hearing loss. Information available, both from animal and human studies, raises the possibility that certain aromatic hydrocarbons are ototoxic. The purpose of this study was to assess whether occupational styrene exposure causes hearing loss in a group of workers in the fibre reinforced plastics manufacturing industry. The hearing acuity of 299 subjects was determined, using pure tone screening audiometry, at the beginning of a single workshift and again at the end of the shift. On …
Cyclic Adenosine 3',5'-Monophosphate And Prostaglandin E(2) During Decidualization In The Rat, Gayle M. Yee
Cyclic Adenosine 3',5'-Monophosphate And Prostaglandin E(2) During Decidualization In The Rat, Gayle M. Yee
Digitized Theses
Prostaglandin E{dollar}\sb2{dollar} (PGE{dollar}\sb2{dollar}) is an important mediator of implantation and decidualization during pregnancy. However, its mechanism of action in the uterus is unclear. Endometrial alkaline phosphatase (ALP) activity increases during decidualization in many species and provides a marker for assessment of cellular aspects of decidualization. The objective of this study was to examine the relationship between PGE{dollar}\sb2{dollar} and cyclic adenosine 3{dollar}\sp\prime{dollar},5{dollar}\sp\prime{dollar}-monophosphate (cAMP) during decidualization in the rat. In ovariectomized rats treated with estrogen and progesterone to sensitize the uteri for decidualization, intrauterine infusion of indomethacin, an inhibitor of endogenous PG synthesis, inhibited the increase in endometrial ALP activity, which occurred …
