abstract: The shakedown deformation of a gravity type offshore foundation subjected to dynamic cyclic wave loading is determined based on the two dimensional finite element formulation of a fluid saturated porous medium. The soil is assumed to behave in an undrained manner and modelled as a two-phase material. The undrained characteristics of the soil leads the Poisson's ratio to be one-half and thus results in a singular stiffness matrix. The reduced integration technique is used in order to circumvent the problem. The dynamic shakedown load factor is obtained by first computing the elastodynamic response of the caisson-foundation (saturated) medium for some adjusted initial conditions (e.g. displacement and velocity) and then solving a linear programming problem based on the dual form of kinematic shakedown theory. -- A finite element computer code OPFA (Offshore Platform foundation Analysis) is developed which computes the dynamic shakedown load factor of a gravity type offshore foundation and then determines the response quantities such as displacements and stresses in the saturated soil medium. The nonlinear stress-strain characteristics of the soil medium is considered in the analysis by use of an equivalent linear and an elastic-perfectly plastic model. -- Several problems are solved in order to check the accuracy of the computer programme. The results are in excellent agreement with the available analytical solutions. The shakedown analysis for a flexible foundation shows – that limit pressures depend on the inclination angle and the eccentricity of the load. The shakedown limit pressure decreases as the eccentricity and the angle of inclination of the load increase. Also, shakedown analyses indicate that the footing pressures are below those predicted by the approximate bearing capacity formula. These shakedown pressures are obtained from an upper bound solution and therefore the use of the above formula will not produce a conservative estimate of the bearing capacity of the foundation when the loading is cyclic in nature. -- The dynamic shakedown load factor for the gravity foundation is only 10% lower than its static counterpart. The reason for the decrease of this load factor is due to the amplification of stresses under dynamic loading condition. In computing the response quantities for three different soil models, it is observed that the equivalent linear analysis predicts lower deformation as opposed to other linear and nonlinear models. However, for the quasi-static analysis of the gravity foundation, the permanent vertical shakedown deformation is within 0.085% of the footing width. In all cases it is observed that shakedown occurs with respect to the deformation of the foundation.

type: Thesis NonPeerReviewed

abstract: Anxiety is one of the primary reasons for referral to mental health services among youth (Costello, Egger, & Angold, 2005). There has been a strong correlation between anxious symptoms and disorders in mothers and children (Hughes, Fun, Sood, Barmish, & Kendall, 2009); however, there are limited studies that demonstrate what symptoms are similar in mother-child dyads. Study One compared parent and child self-report measures of anxiety to test the hypothesis that similar items on these measures assess similar anxiety symptoms. Study Two examined similar symptom pairs determined in Study One to test the hypothesis suggesting there is a relationship between maternal and child anxiety. A total of 58 mother-child dyads participated, with children ranging from 7-17 years of age. Results indicated there was a significant relationship between specific anxiety symptoms. Implications of this study will help to provide a better understanding of how the transmission of anxious symptoms from mothers to their children.

abstract: Objective: The purpose of the study was to develop and validate a noninvasive, easy-to-use method of determining corpus Iuteum (CL) function. -- Methods: This study documented progesterone levels obtained from tampons during menses from 18 women. The new method was compared to information obtained on analysis of progesterone concentrations from finger-prick bloodspots. The participants also kept daily temperature and Menstrual Cycle Diary© records for three cycles. -- Results: CL functioning was evident in 28 cycles and nonexistent in 5 cycles as determined by bloodspot analysis. There was no statistically significant difference in progesterone concentrations extracted from tampons from functional and non-functional cycles (p>0.05). Diary assessment revealed functional cycles had significantly higher scores for the following experiences: side breast tenderness, cramps, fluid retention, frustration, sleep problems, depression, and breast size (p<0.05). -- Conclusion: Progesterone in menstrual fluid may be an inappropriate marker for luteal function but select physical and emotional experiences observed during the menstrual cycle may indicate CL function.

abstract: While working at depth air breathing commercial divers experience nitrogen narcosis and they can become hyperthermic with surface supply heating systems. It is unresolved to what extent narcosis and hyperthermia influence exercise or work ventilation. The 2 studies in this thesis examined the effects of nitrogen narcosis and hyperthermia on phase I and III· of exercise ventilation. The first study examined the effect of 30% normoxic nitrous oxide (N₂O) induced narcosis on both phase III ventilation and on core temperature thresholds for ventilation in 6 male subjects performing an incremental exercise test to exhaustion. The second study examined independent effects of 30% normoxic N₂O induced narcosis and core temperature on phase I exercise ventilation for 6 male subjects exercising in 4 separate 30 s Wingate exercise tests. For 2 Wingate tests subjects remained normothermic for the exercise while for the 2 other Wingate tests prior to exercise they were rendered hyperthermic in a 40°C bath for the test. The first study showed relative to exercise with air breathing that N₂O breathing significantly suppressed exercise ventilation (p<0.05) and the frequency of respiration (p<0.05) while shifting esophageal temperature (Tes) thresholds for ventilation to significantly higher Tes levels (p<0.05). The second study showed a significant (p<0.05) decrease for total ventilation in N₂O normothermic relative to N₂O hyperthermic exercise and this decrease was due to significant decreases in tidal volume (p<0.05). In conclusion, the results support the hypothesis that the control of exercise ventilation includes a neural component as evidenced by nitrogen narcosis suppressing and hyperthermia elevating human ventilation during high intensity exercise.

abstract: The purpose of the current study was to examine minor hockey players' perceptions and experiences of aggressive and sportsmanlike behaviours. In-depth open-ended interviews were conducted with six male minor league hockey players ages 12 to 14. Cote, Salmela, and Russell's (1995) guidelines were used to analyze and interpret the data inductively. Results of the investigation indicated that there were five themes that emerged and were labelled; the aggressive nature of hockey, personal experiences, sportsmanship in minor hockey, experience of sportsmanship, and recommendations for decreasing aggression and increasing sportsmanship. These results provided evidence that players perceived the NHL as being the most influential source of aggressive behaviour, their parents as the most influential source on sportsmanlike behaviour, and retaliation as the main cause of aggressive behaviour. Practically, these findings provide sports administrators, parents, and coaches with information on how to decrease aggressive behaviour and how to increase sportsmanlike behaviour in minor hockey.

abstract: This thesis is an exploration of the identity "Newfoundland Woman". It is a journey that encompasses a number of texts, which include both fiction and non-fiction, historical and modem narratives. These texts are Random Passage and Waiting for Time, by Bernice Morgan, and the narrative texts of my life and my mother's life. It examines the social underpinnings of self-identity through the lenses of queer and postmodern theories. Most important among those are Judith Butler's theory of gender performativity and Linda McDowell's postmodern take on feminist geography. Through the interplay of these theoretical positions, and interconnections between theory and narrative, ideas of what Newfoundland Woman has meant, does mean, and might mean in the future are evinced and expanded.

abstract: The objectives of this study were three fold and these are described in three parts. In the first part incorporation of long-chain n-3 fatty acids (FA) into three types of high-laurate canola oils was examined. Incorporation of the n-3 FA, namely eicosapentaenoic acid (EPA, C20: 5 n-3), docosapentaenoic acid (DPA, C22: 5 n-3), and docosahexaenoic acid (DHA, C22: 6 n-3) into three types of high-Iaurate canola oils, known as Laurical 15, 25, and 35 with 15, 25, and 35% oleic acid content, respectively, was carried out. -- Production of SL via acidolysis of Laurical 15 with EPA, DPA, and DHA was carried out using five lipases from Candida antarctica, Mucor miehei, Pseudomonas sp., Aspergillus niger, and Candida rugosa. Pseudomonas sp. lipase gave the best incorporation of EPA, DPA, or DHA into Laurical 15. Optimum reaction conditions for EPA incorporation into Laurical 15 were 4% enzyme load, and an oil to EPA mole ratio of 1:3 at 45°C over 36 h. For DPA incorporation into Laurical 15, the optimum conditions were 6% lipase amount, and an oil to DPA mole ratio of 1:2 at 35°C over 48 h. Similarly, incorporation of DHA into Laurical 15 was best achieved at a mole ratio of oil to DHA of 1:3, 10% lipase concentration, at 35°C over 48 h. Lauric acid remained mostly esterified to the sn-1,3 positions while EPA, DPA or DHA was also located mainly in the sn-1,3 positions of the modified oils. The modified oils were more prone to oxidation than their unmodified counterparts, as evidenced by the 2-thiobarbituric acid reactive substances (TBARS) test. -- In another study, response surface methodology (RSM) was employed to obtain a maximum incorporation of EPA or DHA into Laurical 25. Under optimum conditions incorporation of EPA (61.6%) into Laurical 25 was achieved using 4.6% enzyme from Pseudomonas sp. at 39.9°C over 26.2 h. The corresponding maximum incorporation of DHA into Laurical 25 was 37.3% using 4.79% enzyme from Pseudomonas sp., 46.1°C, and 30.1 h. For EPA-modified Laurical 25, lauric acid was present mainly in the sn-1,3 positions while EPA was randomly distributed over the three positions. Similarly, DHA as well as lauric acid were primarily located at the sn-1,3 positions of the modified oil. The unmodified oil remained unchanged during storage for 72 h as indicated by the conjugated diene (CD) values, but EPA- or DHA-modified Laurical 25 SL were oxidized to a much higher level than the original oil. The CD values were higher in DHA-modified than EPA-modified oil. The modified oils also attained considerably higher TBARS values than the original oil over the entire storage period. -- Lipases from Mucor miehei (Lipozyme-IM), Pseudomonas sp. (PS-30), and Candida rugosa (A Y -30) catalyzed optimum incorporation of EPA, DP A, and DHA, into Laurical 35, respectively. The maximum incorporation of EPA (62.2%) into Laurical 35 using RSM was predicted at 4.36% of enzyme load and 43.2°C over 23.9 h. Under optimum conditions (5.41% enzyme; 38.7°C; 33.5 h), incorporation of DPA into Laurical 35 was 50.8%. The corresponding maximum incorporation of DHA (34.1 %) into Laurical 35 was obtained using 5.25% enzyme, at 43.7°C, and over 44.7 h. EPA and DHA were mainly esterified to the sn-1,3 positions of the modified oils while DP A was randomly distributed over the three positions of the TAG molecules. Meanwhile, lauric acid remained primarily esterified to the sn-1 and sn-3 positions of the modified oils. The modified oils were more susceptible to oxidation than the unmodified oil, when considering both CD and TBARS values.

abstract: Blind modulation classification (MC) is an intermediate step between signal detection and demodulation, with both military and civilian applications. MC is a challenging task, especially in a non-cooperative environment, as no prior information on the incoming signal is available at the receiver. -- In this thesis, we investigate classification of linear digital modulations in slowly varying flat fading channels. With unknown channel amplitude, phase and noise power at the receive-side, we investigate hybrid likelihood ratio test (HLRT) and quasi-HLRT (QHLRT) -based classifiers, and discuss their performance versus computational complexity. Both classifiers rely on the likelihood function (LF) of the received signal, and the decision is made based on the likelihood ratio test. To compute the LF, the former employs maximum likelihood (ML) estimates of the unknown parameters, whereas the latter uses method-of-moment (MoM) estimates of these parameters. It is shown that the QHLRT algorithm provides a low computational complexity solution, yet yielding performance close to the HLRT algorithm. -- We further study the performance of MoM estimators employed in the QHLRT algorithm, in terms of their variance. We derive Cramer-Rao Lower Bounds (CRLBs) of estimators of the channel amplitude, phase and noise power, for Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK) modulated signals. CRLB provides a lower bound on the variance of an unbiased estimator. The CRLB expressions are evaluated for different signal-to-noise ratios (SNRs) and number of processed symbols. Variance of MoM estimators is compared with corresponding CRLB and numerical results reveal reasonable accuracy of MoM method of parameter estimation, for the SNR range in which these estimators remain unbiased. -- An application of the CRLB to MC is presented, by developing an idealized reference for QHLRT-based classifier. This is referred to as the QHLRT-IR (QHLRT-IR) classifier. The QHLRT-IR classifier employs unbiased and normally distributed estimators of the unknown parameters, with mean as the true value of the parameter and variance given by the CRLB of the parameter estimator. Performance of the QHLRT and QHLRT-IR classifiers are compared. QHLRT-IR provides an upper bound on the classification performance in the SNR range where the MoM estimators of the unknown parameters remain unbiased and normally-distributed. In this SNR range, it is observed that the performance of the two classifiers is close to each other, which indicates the reasonable accuracy of MoM method for such SNRs. It is shown that the classification performance improves with an increase in the number of processed symbols, due to the increase in estimation accuracy.

abstract: The eukaryotic nucleus is organized around a proteinaceous structural framework termed the nuclear matrix. The precise way in which nuclear proteins are ordered to form a nuclear scaffolding remains to be established. In order to study structural and functional aspects of nuclear matrix proteins, it is necessary to clone and characterize their genes. As a first step towards achieving this goal, an immunological screening of a λgt11 cDNA library with antiserum raised against a nuclear matrix preparation was performed. Screening of the >-.gt11 library resulted in the isolation of several immunoreactive positive clones. One of these cDNA clones, λ7E, was further characterized. Immunoblot analysis, using antisera prepared against 7E β gal-fusion protein, resulted in the detection of an immunoreactive nuclear protein with an apparent molecular weight of 52 kDa. Furthermore, cell fractionation combined with immunoblotting showed that, the 7Eb protein was a component of the HeLa cell nuclear matrix cofractionated with nuclei. Subsequent to screening of another cDNA library (λZap II) with a λ7E DNA probe, two overlapping cDNA clones λ8.1 and λ17.1 were isolated. The composite nucleotide sequence deduced from λ8.1 and λ17 .1 cDNA inserts revealed that, the cDNA is capable of encoding a polypeptide of 422 amino acid residues with a molecular size of 49.8 kDa which is very close to the molecular weight of the protein identified by western blot analysis. -- Based upon the nucleotide sequence data the 7Eb protein was found to be rich in basic amino acids (22%). A computer search for similarity to the predicted amino acid sequence of the 7Eb protein did not reveal any resemblance to previously cloned nuclear matrix proteins including the nuclear lamins. -- The amino-terminal half of the 7Eb protein contains a stretch of about 80 amino acids which are very similar to the DNA binding HMG box domain of a number of proteins. The predicted amino acid of the 7Eb sequence also revealed a significant similarity to many of the cytoskeletal proteins. Although the function of the protein identified in this study is not yet known, the presence of a HMG box domain and sequence similarity to cytoskeletal proteins suggest that this protein is a novel DNA binding nuclear matrix protein.

abstract: Glycophorins are a family of human erythrocyte membrane glycoproteins. At least four different sialoglycoproteins glycophorins, A (or α), B (or δ), C (or β) and D (or γ) have been detected in humans. Glycophorin A is the major sialic acid-containing protein of human erythrocyte membranes. It consists of 131 amino acids distributed in three structural domains. Glycophorin A is encoded by a single gene which gives rise to three different mRNAs, large (2.8 kb ), medium (1.7 kb) and small (1.0 kb) in reticulocytes and in K562, a human erythroleukaemia cell line expressing glycophorin A on its surface. -- Six clones were isolated from a cDNA library constructed with K562 cell mRNA in λgt10 phage using as a probe a synthetic oligonucleotide (GPA-N2) encoding amino acid numbers 30 to 40 of glycophorin A. Nucleotide sequencing of the six clones revealed that all contain an identical protein coding region except for the well known glycophorin AM-AN polymorphism and essentially identical 5" untranslated regions. In contrast, clones differ substantially in the length of their 3" untranslated regions. Examination of the 3 ’ untranslated region of the largest clone revealed seven poly(A) addition signals (AATAAA). To study how the single gene encoding glycophorin A generates three different mRNAs, primer extension analysis and Northern blotting experiments were performed. These experiments supported the findings of the cDNA sequencing and revealed that the three glycophorin A mRNAs differ in the length of their 3 ' untranslated region. The primary structure of the three glycophorin A mRNAs is deduced based upon the nucleotide sequence of various cDNAs, primer extension analysis and Northern blotting experiments. A mechanism is proposed for the generation of the three glycophorin A mRNAs from a single glycophorin A gene that involves differential processing of the 3 ' end of glycophorin A pre-mRNA utilizing multiple poly(A) addition signals.

abstract: The experience of low back pain is a common medical occurrence that often interferes with one's routine activities and has been associated with poor physical conditioning. Adequate strength and endurance of the trunk muscles is necessary for various activities of daily living, numerous athletic endeavors and manual labor environments. However, there are many ways to train the trunk muscles which raises the question of which one is the most appropriate. Traditionally, most training programs have involved dynamic resistance training exercises in order to battle muscle fatigue. Moreover, in recent years there has been more of a demand to incorporate methods of instability exercises such as Swiss balls, Dyna discs and wobble boards in order to provide a greater challenge to the trunk musculature. Thus, the objective of this study is to investigate the extent of activation in various muscles of the trunk region during dynamic weight-lifting exercises and isometric instability activities.

abstract: The main findings fall into two categories, that of “structure” and that of “spiritual symbolism.” – After having shown that the poem is composed of distinct units to which appropriate titles could be given, I have explored John Lyerle’s idea of “interlace structure,” applying it for the first to Exodus. The concept of “interlace” sheds new light on the art of variation which forms part of the multi-stranded verbal braids. – Aspects of spiritual symbolism have been discussed under the headings “Time and place,” “The Journey as a way of life,” “Nautical images and their significance,” “The exile,” “Water and blood and the idea of baptism,” “Israel and the Christian soldier,” “Songs, treasure, and the reward in heaven,” “Moses and Christ,” and “The Egyptians and the powers of darkness.” Although all these aspects have been investigated before, new material to support or to reject certain views has been presented. It could be shown that images and phrases used to describe the Egyptians correspond to those used in the Old English Genesis to describe the fallen angels. – In the Appendix a detailed investigation of small capitals and accents is presented. The tentative conclusion has been drawn that small capitals were used as punctuation marks and that accents served various purposes but were mainly used on long vowels. Thornley’s theory that accents were inserted to indicate inflections of the voice within a specific chant is rejected.

abstract: Type 1 diabetes mellitus (T1DM) results from the autoimmune destruction of the insulin producing β cells in the pancreas. In T1DM, insulin deficiency induces abnormal metabolism of glucose, lipids and protein that may result in elevation of reactive aldehydes methylglyoxal and glyoxal. Hyperglycemia and high levels of methylglyoxal and glyoxal can modify cell protein, promoting the formation of advanced glycation end-products (AGEs), which may contribute to the development of diabetic complications. In this research, novel high-performance liquid chromatograph coupled with tandem mass spectrometric detection (LC-MS/MS) methods to measure plasma methylglyoxal, glyoxal and some of AGEs were developed. Plasma methylglyoxal, glyoxal and one AGE (MGH1) were measured in young humans with complication-free T1DM. The activity of the ubiquitous membrane enzyme, Na⁺1K⁺-ATPase, was also assessed. Fifty-six patients with T1DM (DM group), 6 to 22 years, and 18 non-diabetics (ND group), 6 to 21 years, were enrolled in the study. Mean hemoglobin A1C (%) was higher in the DM group (8 .5 ± 1.3; mean ± standard deviation) as compared to the control group (5.0 ± 0.3). The mean plasma methylglyoxal (nmo1/L) and glyoxal level (nmo1L), respectively, were found higher in the DM group (842 ± 238, 1052 ± 515) versus the control group (439 ± 90, 328 ± 208). Plasma free AGE, MG-H1 (mg/L), was also found to be higher in the DM group (2.7 ± 1.1) versus the ND group (1.7 ± 0.9), and weakly correlated with methylglyoxal levels but not glycemia as determined by A1C. Erythrocyte membrane Na⁺1K⁺-ATPase activity (nmo1 NADH oxidized/ min/mg protein) was elevated in the DM group (4.47 ± 0.98) compared to the ND group (2.16 ± 0.59). A1C correlated with plasma methylglyoxal and glyoxal, and both aldehydes correlated with each other. A high correlation of A1C with Na⁺K⁺-ATPase activity, and a regression analysis which showed that A1C was a good predictor of this enzyme activity, suggests that glucose may play a role in promoting membrane alterations. Increased plasma methylglyoxal, glyoxal, plasma free MG-H1 and erythrocyte Na⁺1K⁺-ATPase activity may predict the occurrence of future diabetic complications which may be prevented by early aggressive insulin treatment.

These models were identified by a key word search (child + custody + evaluation + assessment + study + data) of four indexes: Medline (MESH), Social Science Citation Index, Legal Resources and Social Work Abstracts. -- Part 1 conceptually defines and describes the field of child custody assessment and the clinical context in cases of marital dissolution. In Part 2, child custody assessment models are identified, categorized by country of origin (Canada or the United States) and procedurally reviewed by professional orientation (i.e. social work, law, psychiatry and psychology). A formulation for child custody assessment practice as a redefined area of child welfare and an emerging clinical social work specialization is developed.

abstract: This thesis entitled "Distributed Systems and Hardware-in-the-Loop Simulation and Applications in Control Systems" presents a design and implementation of a Hardware-in-the-Loop Simulation with a software model of a process and a real hardware controller. For this thesis, the process simulation tool that has been selected is HYSYS. This software has the ability to model processes from the most simplest examples to complicated industrial processes. The hardware, or controller, that will be used in this thesis is a Modicon Programmable Logic Controller that is often used in many industrial processes. -- There are two main goals for this thesis. The first goal is to design and implement a Hardware-in-the-Loop Simulation environment using HYSYS and a PLC that can be used as a verification tool to verify the correctness of the controller and the process. As well, the results of the PLC controller must also be compared with results produced from a third party software controller to show the effectiveness of using a real controller. The simulation environment must also be done using multiple systems that must communicate over a TCP JIP network to enable remote simulation of the PLC. The second goal is to analyze the effect of time latency on the distributed system. -- The work completed in this thesis will further the understanding of the development of Hardware-in-the-Loop Simulation environments and understand the effects of time latency in a real time distributed system environment.

abstract: In the following thesis, titled "'Wheel within Wheel': The Mystics of William Blake," I discuss William Blake's writing with respect to the debate over whether Blake's poetry and prose is most aptly described as predominantly engaging in the mystical or the visionary. I dispute the interpretation that Blake's works are visionary in opposition to the mystical. Instead, I claim that the visionary analysis of Blake's writing is founded on an exclusionary understanding of the mystical. Moreover, if we take into account the various explications of the mystical and the visionary, then we see that Blake's poetry and prose exhibits characteristics of both the mystical and the visionary. Thus, it is necessary to give an overview of Blake criticism stretching back nearly a century. In doing so, we observe how the critical debate developed over whether Blake is pursuing the mystical or the visionary. Furthermore, it becomes evident that this debate centers on a singular understanding of these terms. An exposition of other interpretations of the mystical and the visionary demonstrates that Blake's works cannot be labeled as either mystical or visionary. Finally, I briefly discuss Blake's final epic, Jerusalem, to illustrate how Blake's writing displays characteristics of both the mystical and the visionary. The conclusion leaves room for further study and research in terms of reading Blake's works with an eye for both the mystical and the visionary and therefore not focusing on one to the exclusion of the other.

abstract: This thesis seeks to illustrate the importance of totality in the philosophy of Emmanuel Levinas. The :first chapter shows how his early struggle with totality is a direct response to Martin Heidegger and the history of Western thought. I understand Levinas' early thought as a reformulation of the Heideggerian distinction between Being and beings and claim it aims at presenting a notion of subjectivity that is not to be interpreted as a totality. The second chapter will take this new notion of subjectivity and show how it results in methodological problems when Levinas uses the language of subjectivity to express the idea of the absolute Other, an idea which escapes all concepts. The textual difficulties mentioned in the second chapter will lead us into a discussion of Levinas' later thought, where I will show that his Saying-Said correlation demands that totality have a crucial and unreducible place in his thought. The need for both 'Same' and 'Other', accordingly, will allow me to evaluate how Levinas' thought fits into the history of philosophy, and how it is at the same time outside it.

Moreover, the political content of the dialogue is not explicated but enacted in the shared friendship of Socrates and Phaedrus. Socrates' concern for his friend compels him to accompany Phaedrus outside the city, from which he has symbolically been alienated in virtue of his enthusiasm for rhetoric. The two friends find themselves vulnerable when outside the city and come to identify the need they each have for one another if they are safely to return. The first half of the dialogue features Socrates' ironic mimicking of Phaedrus in order to bring him to self-knowledge. The second half, conversely, reveals the extent to which Socrates himself lacks self-knowledge. Through an attuned dramatical reading, the Phaedrus reveals that friendship and politics share an essential connection.

abstract: Although the phenomenon of compensatory renal growth has been under inve3stigation for more than a century, its mediation has not been elucidated. The participation of a circulating, kidney-specific growth factor, either stimulatory of inhibitory, has been hypothesized, but tis existence has not been proved. Theoretical considerations predict that in vitro methods could be profitably used in these circumstances, since these methods would allow dissociation of the effects of the postulated factor from the complex physiological changes which accompany compensatory renal growth in vivo. – The work of this thesis consists of the development of a cell culture system suitable for testing serum from previously uninephrectomized or sham-operated animals for the presence of such a growth factor. A method of primary culture of adult Fischer rat kidney epithelium is described. The morphology of these cultured cells is compatible with that of proximal tubule epithelium in site, these being the cells stimulated to divide in vivo by uninephrectomy. The chief finding reported in this thesis is that treatment with serum from rats uninephrectomized 48 hours previously results in consistent, significant increase in uptake of tritiated thymidine by cultures, when compared with control sera from sham-operated rats. Serum from rats uninephrectomized 18-36 hours previously is not consistently stimulatory. Preliminary investigation with this culture system indicates that: (a) the differential effect of control and uninephrectomy sera is due to the presence of a stimulatory factor in the latter rather than an inhibitor in the former; (b) soluble fractions of homogenates of both kidney and liver tissue exhibit inhibitory dose-effects in cultures; (c) xanthopterin, a compound that stimulates kidney tubule epithelial cell division in vivo, has no stimulatory effect in vitro; (d) serum obtained from human kidney transplant donors 24-72 hours after uninephrectomy stimulates increasing thymidine uptake in cultures. – Use of this cultures system has confirmed the existence of a serum factor involved in compensatory renal growth, and should prove to be a valuable tool for its characterization.

abstract: Four Elasmobranchs, 23 Teleosts, 2 Holosteans, 1 Urodele and 2 Anurans were studied. In Elasmobranchs, no vessel is found either in the vitreous cavity or on the retina. The iris artery proceeds through the ventral choroid and sends off a branch to the small lens muscle papilla. Most instances in the Teleosts are classified into 4 types; the higher falciform process, the low falciform process, the low falciform process with branches on the retina, and the vitreal vessels; depending upon the development of the hyaloid artery either into the vitreous cavity along the embryonic fissure or onto the retina. The main vessel which proceeds from the optic disc to the lens muscle tends to be obliterated in the vitreal vessels where the embryonic fissure is closed and the numerous branches on the retina are received by a peripheral annular- vessel. Instances which do not fall into any of these categories are considered to be deviations. The arterial entry near the ventral ora in Holostei is associated with the ventralward elongation of the optic disc. The vitreal vessels of Liparids are unique in that their exit is through the optic disc. Urodela show an avascular condition, while Anura have a well developed system of vitreal vessels where the entry and the exit are at the ventral margin of the ventral lens muscle represented by a small swelling in the ciliary folds. In both, the ophthalmic artery runs along the ventro-temporal meridian of the eye-ball to supply the cilio-iris region. -- The falciform process type vascularization may have arisen from the vitreal vessels due to their being influenced by the development of the accommodative lens muscle, which is functional only in Neopterygii. On the other hand, both in Classes Chondrichthyes and Amphibia, it seems that the less marked lens muscle has not had any significant effect on intraocular vascularization.

Masters thesis, Memorial University of Newfoundland.

abstract: Following the implementation of a mandatory model of continuing professional education (CPE) within the Newfoundland and Labrador (NL) medical laboratory science community, an exploratory study relating to the needs, interests, and attitudes of this unique group of health professionals was conducted. Utilizing a mixed methods exploratory design, this research serves to highlight the CPE preferences and attitudes of the medical laboratory profession of NL. Results indicated that despite historically limited CPE options within the province; NL medical laboratory professionals appear to have strongly positive attitudes towards CPE. Data suggests a preference for modem online learning methodologies and work related educational options. Informal learning methods are identified as significantly important to the workforce and a number of educational barriers to learning are identified including those of financial, personal, or familial nature. This research is of primary relevance to those interested in developing CPE options for medical laboratory technologists and other health professionals.

abstract: Multivariable processes are often found in many industries such as chemical, refinery, and aerospace. The complex and nonlinear nature of multi-input and multi-output (MIMO) systems makes multivariable control a challenging task. Multivariable control become difficult in the presence of loop interactions where different control loops in the multivariable system exhibits coupled behavior in the control variables. When the multivariable system is broken into several single-input-single-output (SISO) control systems, the individual control loops can be characterized by equal number of SISO control problems. However, when interactions exists, an individual control loop will be affected by more than one control variable in the multivariable system. Therefore design of MIMO control systems is often a challenging research area in the area of multivariable control. -- There are many multivariable control techniques which have been developed to address the above issues, including advanced multivariable control techniques such as model predictive control. Among them, proportional integral derivative (PID) control has been the most common in industries. Application of fuzzy logic for control problems have been shown to improve overall performance significantly. Although there are many applications related to SISO based fuzzy PID systems, the application and design of fuzzy PID systems for multivariable systems are less common. The adaptive and nonlinear nature of fuzzy control allows fuzzy PID systems to handle nonlinear systems more efficiently than using linear PID controllers. -- The objective of this thesis is to develop a technique to design and tune PID type fuzzy controllers for multivariable process systems. In this work, the standard additive model (SAM) based fuzzy system is selected to design the rule base. The SAM inference system follows a special volume and centroid of membership based technique for defuzzification. A nonlinearity study has been performed to show the advantages of using a SAM based inference system against traditional min-max-gravity based inference systems. The SAM system is implemented on two fuzzy PID (FPID) systems. FPID type I is designed using Mamdani's style FPID system and constitute coupled rules to define the overall FPID output. FPID type II is designed using a rule decoupled system, in which each PID action is described using a separate rule base. -- FPID tuning is performed using the two-level tuning principle where the overall tuning is decomposed into two tuning levels, low-level and high-level. The low-level tuning is dedicated to devise linear gain parameters in the FPID system where as the high-level tuning is dedicated to adjust the fuzzy rule base parameters. The low-level tuning method adopts a novel linear tuning scheme for general decoupled PID controllers and the high-level tuning adopts a heuristic based method to change the nonlinearity in the fuzzy output. -- The stability analysis using Nyquist array and Gershgorin band proves the robustness of the proposed method. The stability criterion is performed to define the hard limits for nonlinear tuning variables in the SAM system. The proposed FPID tuning technique guarantees the stability of the MIMO control system. -- The applicability of the proposed methods in this research is demonstrated through several control simulations and real-time experiments. The results show FPID systems able to handle such a complex system more robustly than using linear systems and also the experiments validated the design method proposed in this thesis.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: The tropical to subtropical mesopelagic fish genus Polyipnus (family Sternoptychidae) is the subject of a taxonomic, phylogenetic, and biogeographic study. Examination of specimens from most of the major collections leads to recognition of 29 species in the genus. A key is provided. New species are described from the South China Sea, off the northwestern coast of Australia, the Andaman Sea (eastern Indian Ocean), the western Indian Ocean off Kenya, and the tropical western North Atlantic. -- A study of phylogenetic relationships, based on mainly osteology and photophores, results in a well-resolved phylogeny. Instances of unresolved branching order are due to homoplasy and/or lack of osteological observations for rare species. Reductive homoplastic characters, such as small body size (within the omphus species group) and low photophore number (P. fraseri) are paedomorphic and likely derived. Monophyly of the genus and 4 species groups is indicated; the infrastructure of the genus is organized on the basis of these groups. Species that were previously members of the laternatus species complex do not constitute a monophyletic group and are placed in the asteroides and omphus species groups with their closest relatives. The remaining meteori and spinosus species groups contain species previously referred to the asteroides and spinosus complexes. -- Cladograms formed the framework for a vicariance biogeographic analysis. The history of the genus dates to pre-Miocene times (prior to 25 million years ago) when a widespread Tethyan ancestral biota existed. A chronological series of tectonic/climatic vicariant events is proposed which accounts for much of the observed endemism in the genus. The asteroides species group appears to be the only Polyipnus group that was present in the Atlantic as well as the Indo-Pacific in the early Miocene. Final closure of Tethys in the Mediterranean region, later in the Miocene, caused subdivision of a species ancestral to all Atlantic species and possibly a single species in the western Indian Ocean. Subdivision of an ancestral deep-sea fauna in the Indo-Pacific was effected by the early Miocene collision of the Australian and Asian Plates and subsequent tectonic activity which cut off deep water circulation between the eastern Indian Ocean and the western Pacific. Later in the Miocene, circulation between the South China Sea and the adjacent southern Sulu Basin was disrupted, possibly causing vicariance in three Polyipnus species groups.

abstract: This thesis presents the results of a study undertaken to evaluate the feasibility of a low-cost Particle Tracking Velocimetry system to measure two dimensional steady flow vectors. Emphasis was placed on the suitability of the technique for ship propulsion research. -- Experiments were conducted in a cavitation tunnel. Flow illumination was provided by an air-cooled Argon-ion laser with a measured output of 30 mW. An oscillating mirror was used to redirect and spread the laser light into a sheet. The water was seeded with 40 μm Aluminium-Silicate micro-spheres and particle images recorded using a standard Charge Coupled Device (CCD) video camera. High frequency sweeping of the laser beam produced multiple exposures within a single video field. This allowed the system to be used with flow speeds beyond the limit normally imposed by the standard 30 Hz. video framing rate. A desktop computer with a frame-grabber board was used to digitize selected video fields. Particle tracks were analyzed individually using off-the-shelf image analysis software. Velocity was computed by dividing the measured length of the track by the shutter speed of the camera. -- Experiments were carried out in four phases. Measurements were made in uniform flow and found to be accurate and repeatable to within a single pixel. This gave a resolution of 0.072 m/s for a flow speed of 1.656 m/s and a 140 mm x 110 mm field of view. Experiments were conducted to determine the flow field around a smooth cylinder at a Reynolds number of 72,700. The results showed good agreement with potential theory in the region upstream of the separation point. -- To demonstrate applicability of the work to ship propulsion research a set of experiments were done to measure the simulated nominal wake in the region behind a model ship skeg. The static thrust and torque of a four bladed B-screw propeller, both with and without the skeg, was measured in the cavitation tunnel. The effect of the skeg on propeller performance has been evaluated and discussed. -- For the case of no skeg, a comparison is made between the experimental results and predictions of performance as given by lifting surface theory. The experimental values of thrust and torque were 22% and 12% higher respectively than what was predicted by lifting surface theory assuming a uniform wake. -- For the case with the skeg the lifting surface theory, using as input the wake determined by the particle tracking experiments, showed qualitative agreement with experimental measurements in predicting increases in blade thrust and torque in the stalled flow behind the skeg.

abstract: This study examines the conservative dialects of English used by speakers who grew up on two island groups in Bonavista Bay, Newfoundland. The 16 participants (eight males and eight females) had spent their early lives on either Deer Islands or Flat Islands, and at the time of interviewing in 2001, ranged in age from 78 to 93 years. Males and females proved to be very similar in their speech patterns, and only slight differences were found between the two groups of islands. -- This thesis describes the distinctive phonological, morphosyntactic and lexical features of these dialects. The first settlers of Bonavista Bay were almost exclusively of Southwest English ancestry, and this work investigates the extent to which dialectal features of that main source area have survived in the language of these contemporary speakers. As expected, both island varieties revealed a mixture of conservative Southwest England features with typical Newfoundland innovations.

abstract: Drawing on current literature from the last two decades, this report provides a comparative analysis of the duties of a school principal as defined by various researchers and my observations as an intern in a typical school setting. More specifically, this report focuses on what Ubben and Hughes (1987) deem to be the major responsibilities of a school principal: (i) staffing and personnel development; (ii) pupil services; (iii) curriculum development; (iv) finance and facilities management; and (v) community relations. I learned that the roles and responsibilities of a school principal are diverse, complex, and ever changing. While theorists and researchers may attempt to categorize the roles and responsibilities of a school principal, in reality, these categorizations only scratch the surface of the true nature of the job. It is only through actual participation and observation that one can truly appreciate the multi-dimensional role that a principal must play in the overall operation of a school.

abstract: The production and transportation of hydrocarbon from a facilities involves complex process system. The components in such a process system are exposed to extreme operating and environmental conditions. To ensure safe and continuous operation, it is important to identify potential risk sources, and incorporate the risk factors in the designing of the process components. -- The present work develops a novel integrated methodology for the risk-based design of process components. It may be noted that there are lots of process component but specific consideration is given for oil and gas pipeline. Hence, the scope of the work is comprised of time dependent failure scenarios. The failure mechanisms considered here are: internal corrosion, external corrosion, stress corrosion cracking, fatigue failure due to corrosion fatigue and start up/shut down loading for a specific process component. The time independent failure mechanisms i.e. third party damage, earth movement, and material defects are not considered in this study. -- This research considered uncertainties associated with operational characteristics of the process component and included them in the risk-based design framework. The study reviewed different design codes/standards for a transportation system. In the internal corrosion analysis the defect depth was calculated from corrosion rate equations and failure probability was assessed considering the first order reliability method. A similar procedure was considered for external corrosion analysis. In the internal corrosion analysis, the study compared the performance of different codes and standards and listed comparative advantages of one over other. The external corrosion analysis identified the causes of the variability of probability of failure for recommended codes/standards. It is identified that the difference in parameter contribution in the bulging factor are responsible for variability in the bursting formulas. In the stress corrosion cracking (SCC) failure analysis, the stress based failure assessment diagram (FAD) was considered. The authors also proposed a strain based approach for the same analysis. The stress/strain based approach closely calculates the failure probability of the SCC defects. The corrosion fatigue analysis mainly considered the effect of variable amplitude loading (pressure fluctuation) on small weld defects. The Miners rule and Paris law are simultaneously considered for failure assessment. The Rainflow counting method is considered in the analysis for stress block and cycles counting. The failure probability is calculated from the damage caused by the pressure fluctuation. -- The failure probability obtained for an individual event is integrated using fault tree analysis to obtain the overall risk of the system -- The unified risk is minimized to design individual components to achieve the target safety level of the system.

abstract: Having an effective and systematic risk analysis and safety management strategy is imperative to avoid unwanted accidents in any process facility. Fault Tree Analysis (FTA) is a frequently used technique by design engineers for Probabilistic Risk Assessment (PRA). Imprecise, incomplete and vagueness of data can result uncertainty in output from FTA. The Dempster-Shafer Theory of Evidence (DST) addresses the incompleteness in data while fuzzy theory handles impreciseness or vagueness in data. -- A computer aided tool for FTA, ExpertFTA- is introduced in this thesis. Both DST and fuzzy theory arc considered to develop this software tool in order to aggregate knowledge from multiple experts. ExpertFTA can assists users (with little knowledge of FTA) to draw a fault tree and perform the analysis effectively. ExpertFTA helps users to create a fault tree, modify it and store (profiling) data for future reference. Users can perform qualitative, quantitative and sensitivity analysis of the fault tree from DST and fuzzy point of view. It also provides a report based on the generated fault tree. Several established design patterns arc implemented and object oriented concepts of Java, XML and XSLT are used in the development of ExpertFTA. -- None of the currently available commercial software for FTA has the capability of performing analysis based on DST and fuzzy logic. This tool is developed with the anticipation of using it for research purposes and also for industry personnel for detailed risk analysis. It is designed such a way that it can be extended with more functionality in the future.

abstract: Recreational Vehicles (RVs) have enjoyed popularity since their invention in the 1920's. Sociological studies of RV users (or RVers) have demonstrated to date how RVing is associated with retirement, freedom, friendship and reciprocity. However, previous studies of RVer culture have been conducted almost entirely in Southern U.S. locations, which may lead to mislabelling all RV users as snowbirds, those who maintain a traditional home and travel a linear and seasonal North-South pathway. This study focused on identifying and describing the unique subculture of RVers who live and travel in their RVs full-time. This included an examination of the full-time RV phenomenon using several theoretical frameworks, including social organizational typologies, rituals, and rites of passage. I conducted semi-structured interviews with eleven full-time RV travelers staying at a campsite in the northern Canadian province of Newfoundland and Labrador during the summer. Thematic analysis of the interviews suggested the importance of new communications technologies, brand of RV, RVing as tourism, and circular, full-time travel for defining the parameters of the full-time RVer subculture.

title: Risk based asset integrity indicators

abstract: Currently, asset integrity is a major concern and presents challenges to the process industry that cannot be ignored. Assessing asset performance is also a difficult task, due to the involvement of versatile tangible, as well as intangible, assets' performance measuring parameters. Monitoring and assessing asset performance through indicators is gaining popularity in several sectors. However, the lack of a comprehensive set of appropriate indicators' development strategy, quantification technique, and measurement cohesion limit the use of an indicator system. To overcome these problems, a hierarchical framework is developed for identifying indicators and monitoring the performance of the asset. The hierarchical structure attempts to characterize the asset and relate it to a company's strategic goal. The hierarchical structure is based on the three major areas of asset integrity, and provides an opportunity to follow bottom-up perspective for identifying multilevel level indicators. This approach uses a risk metric to classify asset integrity, and risk provides a common ground to integrate leading and lagging indicators. The hierarchical structure is followed because the specific indicator results will have no values unless they are linked to the ultimate goal for ensuring asset integrity by measuring asset performance. Similarly, this framework and indicator will have no values unless a mathematical model is used to quantify the risk information. The analytical hierarchy process is used to determine the weight or prioritization of each level indicator and the aggregation of the indicators' outcomes are done depending on the associated risk. This will eventually aid in assessing asset risk based performance. To validate the developed model and to quantify the condition of assets of a process plant a benchmark study is conducted. The estimated index value will determine the condition of the asset based on the performance risk index scale. As a result, the indicator system can provide a comprehensive view on a process plant equipment status and also can lead to the particular consideration of trends requiring attention.

Through an examination of the recovered British ceramic assemblage, this study seeks to understand the nature of this Anglo occupation at what was a predominantly French site. Ceramic analysis, coupled with the relevant historical documents, suggests that between about 1790 and 1820—when the French fishermen were fighting in the French Revolutionary and Napoleonic wars and so not present in Newfoundland waters—middle class Anglo-Newfoundlander families were carrying out a regional migration from the English Shore to the Petit Nord to prosecute a fishery in these newly vacant harbours.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Objective: Adolescents independently self-medicate for a variety of recurrent pain types (e.g. muscle pain, headache, back pain and menstrual pain). Over-the-counter analgesic use is high among this age group and some research suggests that use is sometimes inappropriate and knowledge is poor. To date, no known research has specifically addressed how adolescents acquire attitudes about pain and pain management and how attitudes affect pain management practices. Two qualitative studies and one quantitative study were designed to address these questions. -- Participants: Study 1 participants were 24 junior high school students from Halifax, Nova Scotia (11 male: M = 13.45 yrs, SD = .93, range= 12-15 yrs; 13 female: M= 13.31 yrs, SD = .85, range 12- 15 yrs). Study 2 participants were 20 parent-adolescent dyads, from St. John's Newfoundland, composed of 20 mothers (M = 42.72 yrs, SD = 5.42, range 29-52 yrs), 10 male adolescents (M = 13.6 yrs, SD = 1.43, range 12- 16 yrs) and 10 female adolescents (M = 13.4 yrs, SD = 1.07, range 12- 15 yrs). Study 3 participants were also recruited in St. John's Newfoundland and consisted of 139 adolescents (50 male, M = 14.24 yrs, SD = .89 yrs, range = 13- 16 years; 89 female, M = 13.83 yrs, SD = .99 yrs, range = 12 - 16 years,) and their parents (6 male, M = 46 yrs, SD = 2.61, range = 41-48 yrs; 133 female, M = 41.85 yrs, SD = 3.26 years, range = 34-50 yrs). -- Method: Qualitative methods were used in both studies 1 and 2. Study 1 employed focus groups in order to determine pain and pain management issues relevant to adolescents, with a focus on peer influences. Study 2 employed semi-structured face-to-face interviews with parent-child dyads in order to determine the parental influences on pain and pain management attitudes and practices. Study 3 employed a survey method delivered via telephone. Adolescent-parent dyads were recruited for studies 2 and 3 in order to assess direct links in attitude and practice, providing evidence for the intergenerational transmission of pain-related attitudes and behaviors. -- Main Outcome Measures: Demographic data were collected from all participants in all three studies (e.g. age, grade, pain type, frequency, intensity, treatment choice) using the Pain Incident Questionnaire. These data were subject to descriptive data analysis. For studies 1 and 2, primary outcome measures were the textual data from focus group and interview sessions. Qualitative content analysis was used to reduce textual data to the central themes that emerged most prominently from focus group and interview sessions. For study 3, the Pain Management Questionnaire was developed to assess pain occurrences (type, frequency and intensity), attitudes toward over-the-counter medications and knowledge about over-the-counter medications. An additional focus of Study 3 was to develop and assess a measurement tool assessing attitudes toward over-the-counter medications. -- Results: Pain complaints reported by adolescents were mainly headache, muscle/joint ache, menstrual pain, sprains and short-term pain associated with acute episodes such as falls or bumps. For adolescents, peers were influential in the expression of pain; gender differences in children's socialization of appropriate pain responses are discussed. In the qualitative studies, mothers were particularly influential in transmitting information about pain and pain management through verbal communications and their own pain and pain management behaviors. Mothers emerged as essential facilitators of their children's independent pain management. The intergenerational transmission of information about pain and pain management strategies was apparent in textual data, but less clear in quantitative data. -- Conclusions: The findings from these studies provide a fuller understanding of the adolescent recurrent pain experience. How adolescents learn about, and develop attitudes toward pain, pain, pain behaviors and pain management strategies are presented in a socio-communications model that stresses the influence of peers and mothers. Contributions to the current pain literature as well as study limitations and future directions are discussed.

abstract: The most common approach to studying the dynamics of globular clusters is to calculate and analyze the position and velocity for each star. The rapid variation of these variables is a limitation of this approach. It is perhaps easier to study star cluster dynamics by analyzing more slowly changing variables, such as the period of a star. In this thesis, I study two particular slow-changing variables of stars in N -body simulations, these being the aforementioned theoretical period, and the angle between the star's closest approach to and its farthest retreat from the center of the cluster. Our work involves fitting these variables to ARMA models, both through careful individual analysis and through an automated procedure. While the ARMA models which we considered could not be successfully fit to these variables, it is possible that an analysis using higher order ARMA models, or possibly GARCHMA models, would be more successful. -- The second portion of this thesis deals with the distribution of forces in a star cluster. A simple approximation of this distribution was given by Holtsmark in 1917. This approximation assumes that the cluster has an infinite radius and a constant density, and thus it assumes the force distribution is not spatially dependent. We showed from studies of simulations that these assumptions are not valid for a real cluster, because stars on the edge of the cluster do not experience the same force, on average, as stars in the middle. A new force distribution which takes this fact into account must be used instead. -- It would seem that research such as the statistical time series models mentioned above, as well as the new force distribution, could eventually lead to the derivation a new set of dynamical equations for star clusters. This work is not covered in this thesis, but is an obvious and quite likely very fruitful continuation which we hope to explore in the future.

abstract: This thesis presents results from a model study of coupled physical-biogeochemical variability in the Labrador Sea. The coupled physical-biogeochemical ocean model (OPA-PISCES) is implemented for three monitoring stations in the Labrador Sea; two of these stations are located on the shelves of the western and eastern parts of the basin, whereas the third station is in the central Labrador Sea. The results of the hindcasting for 1994 are validated with available observations. The results of the sensitivity analysis suggest that the model response to parameter variations differs from region to region. The parameters with highest model sensitivity are identified for each station. The simulated seasonal variability of the low trophic level ecosystem dynamics and their relations to coupled physical-biogeochemical processes are discussed. The seasonal variability of dissolved inorganic carbon (DIC) is driven by the bloom drawdown of surface DIC and export through sinking, while the simulated surface pCO₂ concentration appears to be underestimated throughout the year. Besides the process study of the coupled physical-biogeochemical system at the selected regions in the Labrador Sea, the present study demonstrates the applicability of t he PISCES ocean biogeochemical model for regional coupled physical-biogeochemical modeling.

abstract: The understanding of self-assembly and self-organization processes of colloidal particles are topics that in recently years have received greater attention in physics, in materials science, and in biology. Colloidal systems are often used as "big atoms" to study the fundamental physics of formation of crystals. In this thesis, electric fields at varying frequencies and amplitudes were applied to a charged colloidal system. Variation of the electric field amplitude will change the strength of the self-assembly and self-organization processes. At high frequencies and field strengths, the colloids experience a dipolar inter-particle interaction that will affect the equilibrium structure. At low frequencies, however, the colloids will experience both dipolar and non-equilibrium time-dependent electrophoretic forces. The main purpose of this work was to explore this interplay between dipolar interactions and electrophoretic forces, and study how self-assembly and dynamics is affected by this interplay. From this study, we found a dynamical phase diagram that demonstrates the relationship between structure formation and particle dynamics as the frequency and field strength changes.

abstract: Parkinson's disease (PD) is a highly prevalent neurodegenerative disease characterized by loss of motor control and resting tremor. Mutations in a number of genes, including α-synuclein and parkin, have been associated with inherited forms of PD and many of these genes are linked to the ubiquitin/proteasome degradation system (UPS). Studies of the effects of mutations in these genes suggest that impairment of the UPS is central to PD. Expression of wild-type or PD-associated forms of human α-synuclein in Drosophila melanogaster neurons recapitulates some of the symptoms of PD such as the loss of motor control, development of neuronal inclusions, and degeneration of dopaminergic neurons. Parkin, an E3 ubiquitin protein ligase, may be involved in targeting α-synuclein for degradation. To analyse this interaction I generated transgenic flies expressing parkin under the control of the yeast enhancer upstream activating sequence (UAS). The α-synuclein and parkin transgenes were expressed in combination to examine their interaction in vivo. I showed that expression of parkin prevents the toxic effects of both mutant and wild-type human α-synuclein. Although the yeast protein Gal4 is a key component of the UAS/Gal4 ectopic expression system in Drosophila melanogaster, I showed that this protein can be toxic. Transgenic flies that express high levels of Gal4 in the developing eye show elevated apoptosis in the eye imaginal disc, which leads to a disorganised ommatidial array in the adult. Suppression of apoptosis by expression of the caspase inhibitor p35 prevents this. High levels of Gal4 expression in dopaminergic neurons produce larvae that have excessive apoptosis in the brain and reduced longevity in adult flies. I showed that parkin can suppress apoptosis and development defects in the eye. The ability of parkin to counter the toxicity of exogenous and endogenous proteins may provide great insight into our understanding of toxic protein-induced diseases.

title: Propeller wake impingement on a strut

abstract: An unsteady and strong vortical propeller wake can have significant interaction with a body in its race. Since the pod and strut is located downstream an operation propeller for a tractor-type podded propeller, it faces risks of earlier cavitation on the strut, severe vibration of the pod unit, and noise of the propulsor. The aim of this work is to develop a prediction method for the pressure fluctuation on the surface of the pod and strut. -- The study consists of two parts, experimental and numerical. In the experimental study, a podded propeller was tested in a cavitation tunnel. The tip-vortex interacting with the strut was visually investigated, and the strut surface pressure and the propeller shaft loads were measured. By using a data processing procedure, the load and pressure measurements were broken down into time-averaged and phase-averaged components. These components were then linked to the steady and dynamic performance of the propulsor. Pressure measurements showed that the low time-averaged pressure was concentrated in the area around the leading edge of the strut. The lowest pressure was located on the strut suction side near the junction of the strut and pod. However, the largest amplitude of the phase-averaged pressure occurred on the strut leading edge where the tip-vortex impacts the strut. Based on measurement of the propeller shaft loads, the wake impingement effect on the propeller performance was evaluated. The evaluation was made by comparing the shaft loads measured in two tests with and without the installation of the pod and the strut. These showed that wake impingement had no significant effect on the propeller shaft loads, neither on the steady component nor the dynamic components. -- In the numerical study, a Wake Impingement Model (WIM) was developed and inserted into a panel code, PROPELLA. Simulations of the pressure variation on the strut surface were then conducted using the software. The WIM starts from the relaxed and aligned propeller wake. The motion of the wake sheet was traced step by step. For each time step, every wake panel moved from its previous location to a new position. The new position was determined by the product of the time interval and the local induced velocity. When the wake approached the strut, a scheme was applied to keep the wake from penetrating the body surface. To avoid the large numerical disturbance resulting when two dipole panels get too close, the two dipole panels were merged before the calculation of influence coefficients. Numerical simulations on the same tractor-type podded propeller as that in the experimental study were conducted. Although the amplitude of the pressure fluctuation in the tip-vortex/strut interaction zone was under-predicted, comparisons of the numerical results with the experimental data indicated that the simulated pressure was in good agreement over most of the impingement area. Both experimental and numerical studies with the WIM show that WI has insignificant (around 2%) effects on the propeller thrust and torque.

Masters thesis, Memorial University of Newfoundland.

abstract: Prolonged blockade of nicotinic receptors induces sprouting of axon collaterals at the neuromuscular junction (Holland, R.L. and Brown, M.C., 1980). The present study examined the role of muscarinic receptors in the control of collateral sprouting in the adult hippocampus. It was hypothesised that the state of muscarinic receptor activation could promote plastic change at hippocampal cholinergic synapses. In experiment one, quinuclidinyl benzilate (QNB; 20 μg/2 μl), an irreversible muscarinic antagonist was injected unilaterally into the hippocampus of female Sprague Dawley rats. Beta hydroxypropylcyclodextrin (36%) served as a vehicle which was injected into the opposite hemisphere. Subjects were sacrificed 1, 4, 14 or 21 days after treatment. Brain sections (40 μm) were reacted foracetylcholinesterase (AChE). Increased AChE staining in the area of the injection site was visible at the 4 day interval in the QNB treated hippocampi. No increase in AChE staining was seen at the 4 day interval in vehicle treated hippocampi. Brains examined after a 1 day interval showed increased staining limited to the needle track in both vehicle and drug injected hemispheres which appeared to be a function of blood accumulation. At the 14 day interval staining increases were still present at the QNB injection site but were reduced compared to the 4 day interval. An increase in AChE staining was no longer evident at the QNB injection site at the 21 day interval. These data suggest that irreversible blockade of muscarinic receptors can induce collateral sprouting of AChE reactive fibers in the hippocampus. It is hypothesised that sprouting is rapidly induced and retraction occurs following renewed receptor activation. -- Experiment two assessed the effect of hemisphere, sex and drug dosage on QNB-induced collateral sprouting in Sprague Dawley rats. Quinuclidinyl benzilate (20 μg/2 μl  or 40 μg/2 μl) was intrahippocampally injected into either right or left hemispheres of male and female rats. Rats were sacrificed four days following treatment and brains were reacted for AChE. Acetylcholinesterase positive fiber outgrowth was demonstrated using both QNB doses, in right and left hemispheres and in both male and female rats. Neither variable of experiment two effected the occurrence of AChE positive collateral sprouting in the hippocampus.

abstract: The STS (Science, Technology and Society) movement has become increasingly important in science education in recent years. Science education must now prepare students to live and work in a society that is likely to be even more technologically oriented than today. This implies that students must understand the concept of technology if they are to participate fully in society. Developing a clear understanding of technology is likely to be enhanced by addressing any misconceptions that students may already hold. This study is an attempt to discover how clear are the conceptions and misconceptions about technology that are held by a typical group of high school students in this province. -- A representative sample consisting of 36 students who were likely to participate in a pilot version of the new STS course was selected from participating schools. Attrition resulted in a final sample size of 26. An approximately 30 minute interview was conducted with each student. -- The interview included discussions of examples of science and technology, the activities associated with science and technology, the purposes of science and technology, the relationships between science, technology and society, characteristics of scientists and technologists and sources of information about science and technology. Each interview was tape-recorded and transcribed verbatim. Conceptual inventories were then constructed from each transcript and the data were analyzed. -- The results indicated that a majority of the students did not have a clear understanding of the concept of technology, and, that in many cases, they had difficulty distinguishing between science and technology. Most students could differentiate between activities associated with science and activities associated with technology, respectively. Many students held stereotypical images of scientists and technologists. A majority of the students in the sample felt it was important to be informed about science and technology and that the general population should play a role in the decision-making process for matters involving science and technology. There was some concern expressed by the students that there was not enough information available to them in school about science and technology, even though school was usually their primary source of information.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract: Pain arising from nerve injury is often resistant to conventional analgesics and is believed to have mechanisms distinct from those of normal nociception. To determine if spinal prostaglandins (PG) contribute to tactile allodynia, male, Sprague-Dawley rats were fitted with either i.t. microdialysis or drug delivery catheters 3 days before tight ligation of the left lumbar 5/6 spinal nerves. Ligated rats developed tactile allodynia within 24 h, as evidenced by a decrease in paw withdrawal thresholds (PWT) in the affected hind paw (<4 g vs >15 g control). Allodynia was also characterized by a significant increase in the evoked release of PGE₂. Thus, brushing the plantar surface of the affected hind paw with a cotton-tipped applicator, up to 5 days post-ligation, increased the CSF level of PGE₂ (measured using intrathecal microdialysis - [PGE₂]dialysate) compared to the pre-stimulus control period. In vitro, spinal cord slices were used to determine the effect of PGE₂ on glutamate release. The EC₅₀ of PGE₂-evoked glutamate release (2.4x10⁻¹¹ M; control) was significantly decreased in affected spinal segments of allodynic rats (8.9x10⁻¹⁵ M). In a separate group of rats and beginning 2 days after ligation, the acute i.t. injection of S(+)-ibuprofen (non-selective cyclooxygenase inhibitor), SC-51322 (prostaglandin E receptor antagonist), SC-236 (cyclooxygenase-2 selective inhibitor), or SC-560 (cyclooxygenase-1 selective inhibitor) significantly reversed allodynia. The nitric oxide synthase inhibitor L-NAME had a similar effect to S(+)-ibuprofen, and was subsequently tested using isobolographic analysis. The co-administration of both inhibitors resulted in an additive anti-allodynic effect. To investigate spinal PG as possible early triggers of allodynia, we studied the effects of early post-injury treatment with isozyme selective and non-selective COX inhibitors. Treatment with i.t. S(+)-ibuprofen or SC-560, beginning 2 h after ligation, prevented the decrease in PWT, the brush-evoked increase in [PGE1]dialysate, and the change in EC₅₀ of PGE₂-evoked glutamate release. In contrast, lot. R(-)-ibuprofen or SC-236 had no effect. The results of this study suggest that: a) spinal PG synthesis is triggered by spinal nerve ligation; b) pharmacological disruption of PG synthesis or signaling can transiently reverse established allodynia; c) spinal PG, synthesized by cyclooxygenase (COX)-1 in the first 4-Sh after ligation, is a critical trigger of allodynia; d) spinal nitric oxide appears to act in concert with PG to mediate allodynia. Together, it appears that allodynia resulting from L51L6 spinal nerve ligation is comprised of an initial, time-limited, PG-dependent stage (characterized by brush-evoked increases in [PGE₂]dialysate and sensitivity to COX-2 inhibitors) and long-term, PG-independent allodynia. The ability of appropriate COX inhibitors to prevent both stages suggests that the two are related.

abstract: The main purpose of this study was to produce a videotape program utilizing the basic instructional aids for beginners in archery. Provisions for progression in competence in the sport geared to the students' interests was also an important consideration. Furthermore, the program was to be tested to determine if the students, after viewing the videotape, would reach certain predetermined levels of knowledge. -- I An Introduction to Archery,' the title of the program, was produced at St. Clare's Mercy Hospital, in St. John's, Newfoundland, and dealt with a comprehensive body of knowledge that a beginning archer would require. -- The participants of the study were twenty Grade Ten students from Gander, Newfoundland, and twenty physical education majors from Memorial University of Newfoundland. The pretest was administered to the students from Gander and they were then permitted to view the videotape production in total. For the Gander students the viewing was immediately followed by the posttest. In lieu of this test, the physical education majors at Memorial University of Newfoundland were given a reaction questionnaire to subjectively analyze the contents of the videotape and their reactions were tabulated. -- Evaluation was attempted in three ways: (i) a t-test of dependent means, (ii) a Percentage Analysis, and (iii) an Item Analysis. -- On the basis of the evaluative data a significant improvement from the pretest to the posttest period was evident in all students tested. Also, other investigative techniques, such as, the questionnaire and informal conversation gave further evidence which strongly suggested that demonstration by a skilled instructor on videotape resulted in (i) teaching beginning motor skills, (ii) providing uniformed-controlled presentation, and (iii) in arousing student interest in archery. The results of the project tended to suggest, then, that when live demonstrations by a skilled instructor are not available, video demonstrations are recommended.

Masters thesis, Memorial University of Newfoundland.

abstract: During the early 1990s, the collapse of the northern cod stocks resulted in the mass unemployment and loss of income of tens of thousands of Newfoundlanders and Labradoreans. During the early years of the moratorium, individuals who were directly impacted by the collapse of the fishery were receiving income support through The Atlantic Groundfish Strategy (TAGS). The TAGS program ended in 1998, while the moratorium on the northern cod stocks continued. -- The continuation of the moratorium and the discontinuation of the TAGS program means that individuals who have been highly impacted by the cod moratorium may be more financially strained, and subsequently may be more stressed now than they were during the time when TAGS was in place. The misuse of alcohol has been linked with low income and stress, among other factors, and has been shown to have negative health consequences. The purpose of this study was to assess how the consumption of alcohol among drinkers and among specific groups of high-risk drinkers changed from the time when TAGS was in place to the time after the TAGS program had ended. The study included a random sample of 1352 persons in the Bonavista Headland area of Newfoundland and Labrador, of which 800 were drinkers. -- The study found that alcohol consumption among drinkers had decreased from the time when TAGS was in place to the time after TAGS was discontinued. Further, alcohol consumption had decreased among drinkers of low-income households, males and unemployed drinkers. Alcohol consumption had not changed among low-income individual drinkers, drinkers who were single, and drinkers who perceived themselves as stressed.

abstract: A series of laboratory experiments supplemented by field observations of caged mosquitofish (Gambusia affinis Baird and Girard) were employed to investigate the food selectivity of these predators. Various food organisms of approximately similar size were utilized. These included insect larvae, fish eggs, young fish and microscopic organisms. The probable effectiveness of this viviparous poeciliid as a predator on Newfoundland freshwater fish, was evaluated on the basis of these investigations. -- Variation in the forage organisms' external appearance, body covering, behaviour and activity affected Gambusia's ability to utilize different organisms. Also, certain organisms both with soft and hard body coverings, were not taken by the fish. -- Conditioning does not lead Gambusia to select fish eggs and young fish. However, the latter were readily eaten, especially in the absence of other food. Mosquitofish selected smaller eggs and young fish when available. The maximum sizes of eggs taken by small (33 - 36 mm in length) and large (38 - 46 mm) Gambusia approximated 4.2 mm and 4.7 mm in diameter respectively. Mosquitofish of these same size-ranges took young sticklebacks up to 18 mm and 20 mm in length respectively. However, the maximum size of soft-bodied tadpoles preyed upon in this fashion proved much larger than that of sticklebacks. Tadpoles were in fact preyed upon when approximately two-thirds as long as the largest female mosquitofish. Observations of Gambusia predation upon other food organisms were made as well. Cannibalism by female Gambusia upon both adult males and young was also noted. -- The ingestion of microscopic phytoplankton seemed to be on a completely random basis. No special preference for any particular algae over others was shown by the fish. That is to say, the higher the incidence of a given food organism in the tank, the higher its incidence in mosquitofish stomach contents. -- Lowered temperatures adversely affected the growth rate of mosquitofish both in tanks and in cage under stream conditions. Growth rate of fish in aquaria was fast at temperatures of 22.8 - 25.7°C, slower at 14.5 - 17.0°C and poor at 5.5 - 6.1°C. The amount of food taken also decreased with lowered temperatures. Under stream conditions, steady losses in weight and the amount of food eaten were also detected. This is considered to have been due to rapid diurnal changes of water temperature, especially towards the lower end of the range. However, lowered temperatures did not seem to be fatal to the fish, more than 50% of them surviving for 12 weeks.

abstract: The study examines the experiences of individuals who, if given their time back, would have chosen a different career path. Despite the fact that career has been consistently documented as a major life regret for many it is rarely mentioned, or only referred to tangentially, in career development literature. Five individual interviews, four female, one male, with people retired or transitioning to retirement are presented to explore the experience of regret as it persists throughout the adult lives of participants. Although the narratives shared by participants are unique and deeply personal, common themes emerged through qualitative analysis. Four themes relate to perceptions of the past: Early Influences, Why I Regret My Choice, The Passage of Time, and Balancing Work and Family. One theme relates to the present: If I Could Do It Over Again, and one to the future: What the Future will Be. Findings from the current study add to the limited research on the topic of career regret and implications for theory and practice are examined.

Masters thesis, Memorial University of Newfoundland.

abstract: This report outlines an 11-week internship program completed in Harlow, England to comply with regulations set out for the degree of Masters of Education in Educational Psychology. The internship route was chosen by this intern because unique insights are gained and practical training is received through an on-site placement. This report is comprised of three chapters discussing this intern's placement and goals/objectives including rationale, implementation, and evaluation of same. In addition, a comprehensive literature review and an in-depth study of educational psychologists' practices as they pertain to Attention Deficit Hyperactivity Disorder is provided. A semi-structured interview schedule was utilized with four practising educational psychologists in St. John's, Newfoundland and four practising educational psychologists in Essex England. Responses formed the basis for a comparative analysis. Results indicate that the referral and assessment of ADHD is seen to be ad hoc in both areas. Although the education systems are structured differently, the referral processes lack both structure and procedure. Results also indicate that Newfoundland psychologists rely heavily on standardized assessment tools while British psychologists place more importance on the child's environment. No individual interviewee reported completing a comprehensive battery for the assessment of ADHD. The diagnosis of ADHD is seen as the domain of the medical doctor in both Newfoundland and England. Educational psychologists in both areas feel they should have a greater input into the diagnosis. This non-collaboration between health education and psychology is a great concern to educational psychologists in both areas. The creation of a multidisciplinary team and more education are seen as answers for a complete and thorough evaluation of the child and his/her environment.
