abstract:
In Parkinson disease (PD), the age-dependent degeneration of dopaminergic neurons (DA) and loss of locomotor function have been shown to be correlated with prominent mitochondrial abnormalities and dysfunction. A number of genes are associated with inherited forms of PD and most of these genes encode protein products that interact with components of the mitochondria. The pro-survival Bcl-2 proteins are reputed to be the guardians of the mitochondria, an organelle central to the process of cell death in all animals. Drosophila melanogaster possess two mitochondria localized Bcl-2-like proteins encoded by debel, which promotes cell death, and Buffy, which is pro-cell survival. The Bcl-2 proteins have been shown to have a dual role in the control of cell death and subsequent engulfment of cellular components (autophagy).
In the α-synuclein-induced Drosophila model of PD, Buffy and debel were overexpressed in the DA neurons and developing eye using the UAS-GAL4 system of directed gene expression. Longevity and climbing ability of these flies were influenced by these two Bcl-2 genes: debel enhances the severity of the α-synuclein-induced age-dependent loss of climbing ability. On the other hand, Buffy suppresses the α-synuclein-induced PD-like phenotypes. When overexpressed in the developing neurons of the eye, a similar trend was observed with Buffy suppressing the eye defects. Taken together, these results suggest a protective role for Buffy, especially under α-synuclein-induced protein toxicity.

Masters thesis, Memorial University of Newfoundland.

type: Thesis NonPeerReviewed

abstract:
As Caddy noted, "access to and allocation of fish resources remains one of the most
difficult and controversial aspects of fisheries management in Canada and abroad"
(Dooley, 2004). It is generally agreed that access and allocation issues associated with
harvesting rights remains a divisive and contentious issues for participants in the
province's fishing industry. This is particularly true for Aboriginal groups in the
province who have been challenged to capitalize on economic development opportunities
associated with the fishery.
The Department of Fisheries and Oceans (DFO) has the challenging responsibility of
responding to the demands of a range of provincial and territorial jurisdictions while at
the same time considering the access/allocation needs of Aboriginal groups throughout
the country. Various mechanisms have been introduced over the past decade to assist
DFO with these access decisions. The Independent Panel on Access Criteria (IP AC)
introduced in 2001 was one of these initiatives. IP AC was tasked with finding a solution
to the decision making process involving access and the associated ranking or weighting,
and defining access criteria. !PAC was successful in identifying various access principles
and criteria but it did not fully address some of the outstanding problems related to
access. It is important to note that the IP AC suggested that the issue of Aboriginal
participation and access to the fishery required special consideration in the Panel's
deliberations, due to the constitutional position of Aboriginal peoples.
The Aboriginal Fisheries Strategy (AFS) was the other initiative designed to respond to
the needs of the Aboriginal people in the country. Introduced in 1992, the AFS was
intended to help DFO manage the fishery in a manner consistent with the Sparrow
decision. It was intended to serve as a bridging arrangement in fisheries management
during the negotiation of comprehensive land claims and self-government agreements. It
applies where DFO manages the fishery and where land claim settlements have not
already put in place a fisheries management framework.
This paper attempts to illustrate how various Aboriginal groups have been marginalized
over decades as it relates to the fishery and presents a series of court decisions to
illustrate this point. The paper also offers a comparison of the access and allocation
criteria associated with the proposed Federal Fisheries Act and those currently in place
under the AFS. A significant part of the paper addresses the historical perspective of how
Aboriginal groups have been treated by the Federal Government, the Courts, and by
society in general. These historical references are essential to fully appreciate the plight
of the Aboriginal people and their frustrations in experiencing their rightful place in the
country and their right to achieve a reasonable livelihood from the fishery.
The paper will also highlight some of the experiences of other Aboriginal peoples in
other parts of Canada, in order to provide a clearer picture of how Aboriginal rights have
evolved in Canada.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract:
This thesis defends a holistic approach to fish dynamics, supports size as a factor
determining functional groups in a community, and presents a model that can serve as a
framework for the integration of biological knowledge of fish communities with decision-making
about resource exploitation.
We discuss the aspects that should be considered to approach the study of fish
species dynamics. In their natural environment fish species dynamics are influenced by
the presence of other species. Interacting species form a community that lies at the core of
this thesis. Fishery and survey data show drastic changes in the Newfoundland demersal
fish community during the period from the late 70s to the early 90s.
We use these changes to analyse size as an indicator of species response to
fisheries. We find that size at the community level can substitute for species to determine
functional groups that direct community dynamics.
This size-based approach shows properties of the community that cannot be
explained by looking at each single species one at a time. Thus, a size-based simulation
model is built to analyse long-term community dynamics and its response to fisheries.
The model has only three simple assumptions: (1) fish pass through a series of age-determined
size classes through their life history, (2) big fish eat little fish, and (3)
predation cannot drive species to extinction. The model is stable over runs of centuries,
and from a stabilized state can be used to explore several scenarios involving
environmental and fishery disturbances.

abstract:
This thesis follows in a long tradition of Folklore Studies that have focussed on the
relationship between technology and folklore. In this case I examine the use of the
Internet as a medium of communication which can be used to facilitate the formation,
maintenance and propagation of folk groups. Consequently this thesis interrogates the
potential for folklife online. To do this, I have conducted a "virtual ethnography" of an
online group of fans of the English Association Football team: Middlesbrough Football
Club.
The study presented here is an exercise in the examination of the methodology of
virtual ethnography as much as it is an examination of the case study at hand. It is also an
examination of a potential intellectual framework for a folkloristic study of culture
online. Consequently this thesis assays three main tasks. Firstly it contextualises the
Internet as a 'place' in which folklore can be studied. Secondly it assesses virtual
ethnography as a methodology for the study of folklife online and, thirdly, it applies the
methodology to the study of an online group.
The research draws upon the "ethnography of speaking" and applies it to online
communication. It does so within a tradition of interest in orality and literacy as applied
to computer-mediated communication. The football fan group was chosen as a case study
to enable the investigation of a complex set of online behaviour that seemed to challenge
notions of what constitutes oral and literate behaviour online. It is my contention that
complex negotiations of identity and group norms are encoded in emergent
communicative rules and that the resultant group's folklife problematises many long-held
notions that posit an egalitarian ethos for such groups which is grounded in the depiction
of the Internet as a communications medium that lacks key communicative features.

Masters thesis, Memorial University of Newfoundland.

abstract:
The purpose of the internship at MacDonald Drive Elementary
School was to give the intern an administrative perspective of
recent innovations in education. The writer had realized for some
time the need for a child-centered approach to teaching and
learning, and the notion of nongradedness seemed to meet this need.
The writer felt that an adequate administrative perspective on
nongradedness could best be obtained if, as an administrative
intern, he could relate certain theoretical aspects of nongradedness
to real test situations. To help accomplish this goal, the intern
included in the objectives for the internship the development of
instructional improvement aids.
Specifically, the intern became involved in the following
tasks:
1. Developing a learning sequence i n primary language arts
2. Developing diagnostic procedures
3. Developing a curriculum guide
4. Developing an internal recording system
In addition to the development of instructional improvement
aids, the writer was equally interested in exploring general
principles of educational administration. An understanding of the
broad areas of educational administration was readily achieved
by observing an administrator function in actual school situations,
as well as by participating in the actual decision-making process.

abstract:
In this thesis we explore the gradings by finite groups on Lie algebras of type
D₄ over the field of complex numbers. For gradings on simple Lie algebras
several approaches have been studied. In (9], Onishchik and Vinberg give an
exposition of the results of V. Kac who had classified all automorphisms of
finite order in all simple Lie algebras, hence classified the gradings of such
algebras by finite cyclic groups.
J. Patera and co-authors (5], (6], (7] have focused on "fine" gradings and
approach this with the help of maximal Abelian subgroups (MAD-subgroups)
of diagonizable automorphisms in Aut(gl(n, C)). More recently Y. Bahturin,
I. Shestakov, M. Zaicev (1] have approached gradings on simple Lie algebras
by finite groups by looking at the dual group action which will be the main
approach used in this paper.
The gradings on simple Lie algebras of type D₁, l > 4, have been described
by Y. Bahturin and M. Zaicev in (4]. This was done by looking at gradings
on the full matrix algebras and noting that for a realisation of a Lie algebra
of type D₁, l > 4, as K (M₂₁ , *), the skew-symmetric matrices with respect
to a transpose involution *, the automorphisms of K(M21 , *) can be lifted to automorphisms of the full matrix algebra. The gradings on Lie algebras of
type D₄ were not described in [1] or [6] because some of the automorphisms
of these Lie algebras cannot be lifted to the full matrix algebra.
In this thesis we apply the same approach as [1], [2], [3], [4] to describe
all gradings that can be lifted to the full matrix algebra and all gradings that
are isomorphic to these gradings. We also develop an approach inspired by [9]
which may be fruitful for describing the remaining gradings. We give examples
of some of these gradings.

abstract:
Model towing tank testing is used to predict the powering required for full-scale vessels.
The International Towing Tank Conference of 1978 developed a method that has been in
use in its original or modified form in many institutions internationally. Originally the
method was solved graphically, utilizing the experience of the analyst, however the use
of computers and the automation of the method has impacted the reliability of this
approach. Uncertainty analysis has up to this point focused on potential errors in the
model data from the tests required to produce the data that is subsequently extrapolated
using prediction methods. The overall sensitivity of predicted power from this and other
prediction methods to variations in inputs from the model tests and from elements such as
the frictional resistance coefficient, form factor or correlation allowance needs to be
determined in order to properly interpret the results of an automated analysis. Rather
than setting up a series of data reduction equations, a Monte Carlo simulation was used
and the entire method was used as the data reduction equation in the uncertainty analysis.
The levels of uncertainty in ship powering were obtained for assumed values of
uncertainty in the experimental values from tests and for estimated uncertainty in the
friction coefficients, wake fraction and wake scaling, thrust deduction fraction, form
factor and correlation allowance. Several different extrapolation methods were studied to
assess variation in powering prediction methods resulting from variation in input data and
from the variation of the details of the extrapolation. These consisted of the ITTC 1978
method, variation that included extrapolation with and without a form factor, different
friction lines and correlation allowances, different wake scale and thrust deduction
fraction values, and a method that extrapolated from self-propulsion test data only
analysed using the same procedure. Uncertainties in the predicted powering results of
both methods were compared. Methods of reducing the uncertainty in the predicted
power from the ITTC 1978 method were proposed.

abstract:
The ship hydrodynamics literature contains little information on a hull at a yaw
angle greater than that commonly encountered in ship manoeuvring. New ship
types, such as escort tugs with very low aspect ratio fin keels, will benefit from
an analysis of the hydrodynamics that occurs at yaw angles between 20 and 45
degrees. Computational Fluid Dynamics (CFD) is an important technique that
could be used for this analysis, but the accuracy of predicted forces and flow
patterns at high yaw angles was unknown prior to this research.
A new data set of three-dimensional flow vectors in planes around an escort tug
model was obtained using Particle Image Velocimetry (PIV). These data were
used to validate the flow vectors predicted by a commercial CFD code. As part
of the validation study, a method for numerically analyzing the difference
between measured and predicted flow vectors was developed. The method was
used to evaluate CFD predictions of flow patterns around a conventional hull (at
10 and 35 degrees yaw) against published experimental results.
The type of computational mesh was found to affect the accuracy of the forces
predicted for a hull with a yaw angle, but different hull types needed different
meshing approaches. The forces at 10 degrees yaw for a typical high-speed
merchant ship were predicted to within 5% of experimental results using an unstructured tetrahedral mesh, whereas a structured hexahedral mesh gave force
predictions accurate to within 15%. For the escort tug model, which was a wider
and shallower hull shape, the situation was reversed, and the structured mesh
gave force predictions accurate to within 5% of the experimental data up to 40
degrees yaw. There was no noticeable difference in the predicted flow patterns
between meshing approaches for the tug model. Mean flow vector magnitudes
were within 10% of measured values.
As a result of this research PIV has been developed into a practical technique for
measurements around a hull with a yaw angle and CFD has been shown to give
insights into the flow around an escort tug and its appendages, within a specified
level of accuracy.

abstract:
In order to investigate more fully the steric
influences in the B-band of the ultraviolet spectrum,
several acetophenones were prepared, giving molecules
in which the angle between the planes of the electron
rich centers varied. It was found that the light
absorption maximum moved to shorter wavelengths
as the amount of hindrance about the carbonyl group
was increased, (i.e., as the interplanar angle
was increased), and that steric hindrance increased
in the order hydrogen atom <. ortho-methylene group
of the cyclopentyl ring ( ortho-methyl group z orthomethylene
group of tbe cyclohexyl ring ( an orthomethyl group ''buttressed'' by a methyl group in the
adjacent meta-position.
The carbonyl group becomes less readily accessible
as steric interference is increased, as shown
by the inability of the highly hindered ketones
to form the ordinary ketone derivatives. In the
highly hindered ketones, conjugation is inhibited
to such an extent that the main peaks closely
correspond to those of the substituted benzenoid
hydrocarbons.
The spatial orientation of the compounds is
discussed by interpreting the spectra in terms
of the electronic and steric effects of the substituents.
The 2,4-dinitrophenylhydrazones of the unsubstituted
compounds, and some of the substituted
aompounds are included, and it was found that the
amount of steric hindrance c,an sometimes be estimated
by color, 1.e., as conjugation increases, the colors
tend from yellow to red.
A recent example from the literature on the
spectra of substituted hydroxybenzoic acids is
included, and it was found possible to correlate
nicely the observed spectra by means of the theories
of ster.ic and el1ectronic effects.
In the experimental part, the syntheses of the
ketones are described, along with the reaction of

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract:
Hepatitis B virus (HBV) causes lifelong liver disease in up to 400 million persons
worldwide. The true extent ofHBV exposure is unknown, but could be as high as 2 billion
people. This is mainly due to the existence of occult infection and the inadequate sensitivity
of HB V -specific serological assays. Fallowing our previous findings indicating that the
lymphatic system is a site ofhepadnavirus replication, the aims of this study were to determine
virological factors underlying hepadnavirallymphotropism as it pertains to virus persistence.
Specifically, we focussed on the identification of how virus dose and the potential existence
of variants may induce lymphatic system-restricted infection. We employed the
woodchuck/woodchuck hepatitis virus (WHV) system, which represents the closest
pathogenic model of human HBV infection and hepatitis B.
Our results revealed that a significant portion of circulating lymphoid cells are infected
with WHY, whether or not infection is serologically evident or occult. This was documented
by applying an in situ PCR combined with flow cytometry technique, established during this
study, that enumerated WHV -infected cells without the necessity of nucleic acid extraction.
We identified that primary occult WHV infection, that is normally limited to the
lymphatic system, is induced by exposure to low doses ( < 10³ vge) of wild-type virus and is
unlikely due to infection with or the appearance of viral variants inclined to preferentially
invade lymphoid cells. We also showed that exposure to small amounts ofWHV ( < 10³ vge)
did not induce protective anti-viral immunity in that the infected host remained susceptible to
infection with large WHY doses.
In a subsequent in vitro study, we documented that WHY could be serially passaged
in both lymphoid cells and hepatocytes, which does not lead to the emergence of cell typespecific
virus variants. The passaged WHY maintained its infectivity and pathogenicity when
administered to virus-naive woodchucks. This proved that lymphotropism is a natural
propensity of wild-type WHY in both in vivo and in vitro conditions.
By analysing animals intrahepatically transfected with recircularized, complete
recombinant WHY DN~ we documented that recombinant WHY DNA initially establishes
infection in lymphoid cells and, at this location, infectious virus is produced. The infection
of the liver was always secondary.
Since dendritic cells (DC) are known to be a reservoir of virus replication in many
persistent viral infections, we aimed to recognize whether this lymphoid cell subset is also the
site of WHY persistent replication. We prepared monocytic derived DC from animals with
serologically evident and occult chronic WHY infections and demonstrated that DC are
indeed one of the cell types where the virus persistently propagates.
The new features of hepadnavirus infection uncovered in this study imply that when
the host is exposed to a low hepadnavirus dose, the lymphatic system is a primary target of
invading virus. Because of the similarities between WHY and HBY, it is reasonable to
assume that infection of lymphoid cells also plays a major role in the initiation and long-term
persistence of HB V in humans.

abstract:
Being a primary investigator in a participatory action research was the highlight of
my graduate studies. The research involved women with disabilities, an academic, a
community leader of a local disability organization and me, a woman with disabilities and a
graduate student in Women's Studies. The research examined issues of employment and of
knowledge of adaptive technology by women with disabilities. Adaptive technology is
whatever hardware, software, or environmental adaptations a person needs to enable gain
computer access.
As a secondary analysis this thesis takes the form of a case study that reflects back
on the primary participatory action research initiative through critical discourse analysis.
Feminist case study enables examination of social phenomena through an individual case
rather than as a comparative analysis. Throughout the case study it becomes apparent
issues of difference and representation arose that challenged varying historically
constituted knowledges and practices located within both the disability organization and
the university. This study answered the research question how do issues of difference and
representation influence participatory action research process.
Data for this qualitative study involves portions of the ethical submission, personal
correspondence, emails, journal entries written during the primary research and three
sections of university policy. Each source of data through critical discourse analysis
illustrates the impact of difference of perspective and issues of power within partnership.

abstract:
This thesis examines the phenomenon of recovery as it is experienced and understood by
members of Alcoholics Anonymous in Newfoundland and Labrador. Recovery involves more
than just changes in the brains and bodies of the addicted person. It is more than changes in
positive affect, mood or personality structure. Recovery is more than the gradual modifications
of behaviour associated with learning models. In this dissertation, I present a new and alternative
interpretation of recovery by applying insights from the fields of ritual theory and dramaturgy. A
qualitative research design, using participant observation and in-depth interviews, were used to
generate detailed descriptions of the social processes involved in recovery. Data generated from
these methods have yielded new insights into the inner workings of AA not yet described in the
existing sociological literature. Data from this study reveal recovery as a dynamic social process
wherein the novice AA member, referred to in this study as the penitent, experiences dramatic
personal change and transformation through the twelve step program. The experience of working
the twelve steps is presented in this study as a personal rite of passage involving three phases of
transformation: separation, liminality and incorporation or aggregation. At each stage of this
transformational process the AA member must follow certain emotion display rules and learn
how to work with others in the home group to become a contributing member of a performance
team. The emotions and behaviours associated with recovery are thus strongly influenced by
social factors which are unique to the subculture of AA. Findings from this study have the
potential to flesh out and expand conceptual models of recovery and to better inform social
policy on addictions.

Masters thesis, Memorial University of Newfoundland.

abstract:
A fumigation model based on probability density function (PDF) approach is presented
here to study the dispersion of air pollutants emitted from a stack on the shoreline. This
work considers dispersion of the pollutants in the stable layer and within thermal internal
boundary layer (TIBL) proceeds independently. The growth of TIBL is considered
parabolic with distance inland and turbulence is taken as homogeneous and stationary
within the TIBL. Dispersion of particles (contaminant) in lateral and vertical directions is
assumed independent of each other. This assumption allows us to consider the position of
particles in both directions as independent random variables. The lateral dispersion
distribution within the TIBL is considered as Gaussian and independent of height. A
skewed hi-Gaussian vertical velocity PDF is used to account for the physics of dispersion
due to different characteristics of updrafts and downdrafts within TIBL. Incorporating
finite Lagrangian time scale for the vertical velocity component, it is observed that it
reduces the vertical dispersion in the beginning and moves the point of maximum
concentration further downwind. Due to little dispersion in the beginning, there is more
plume to be dispersed causing higher concentrations at large distances. The model has
considered Weil and Brower's (1984) convective limit to analyze dispersion
characteristics within TIBL. The revised model discussed here is evaluated with the data
available from the Nanticoke field experiment on fumigation conducted in the summer of
1978 in Ontario, Canada. The results of the revised model are in better agreement with
the observed data, as compared to other available models. The study suggests the use of mean absolute error and mean relative error as quantitative measures of model
performance along with the residual analysis.
For easy and effective use of the newly developed model, user-friendly computer
software 'Fumig' is developed in visual basic. Fumig is built upon the developed model
and enable easy assessment of concentration profiles under fumigation conditions.

abstract:
A child welfare court decision to grant the adoption of two Aboriginal children to non-
Aboriginal parents despite the extended family's ability to care for the children and the
community's leaders desire to repatriate their citizens raises two key issues that will be
addressed in this study. The first key issue examines Ojibway parenting and their
responses to common family challenges. The Ojibway culture had and continues to have
pre-existing parenting and child development knowledge but it is largely unknown to
professionals who provide various services to this population, i.e., judges, social workers,
and psychologists. The history and context of Aboriginal families in Canada and the
influence of culture in parenting is explored in the literature. The historical pattern, when
dealing with Aboriginal families in Canada, is to favour ideas or solutions that can be
called "European," or "Western" in origin. This means that Aboriginal ideas or solutions
to their family or parenting problems are ignored or devalued. The second key issue is
that Aboriginal families, First Nations leaders, and Aboriginal service providers have
encountered child welfare court decisions, child welfare policies, and social work practice
that rely on the premises of attachment theory. The (over) reliance on attachment theory
has meant that Aboriginal children have been removed from their parents and/or their
communities when alternative solutions exist. For the above reasons, this study explores
the role of Ojibway culture on urban Ojibway parents' perspectives utilizing a Talking
Circle format. Ojibway participants' words and the meanings attributed to parenting
practices are compared to attachment theory's sensitivity and security constructs.
Urban Ojibway parents lean towards the Ojibway culture for information on parenting
values, practices, perspectives, ceremonies and customs. Relying on Ojibway parenting assumptions and practices that are not supported in an urban environment produces a
discontinuity from participant's childhoods and parenting assumptions. Thus, the urban
context exerts its influence by creating conditions of parenting that previous generations
of Ojibway parents in First Nations communities did not have to consider and solve. The
implications for Ojibway parenting perspectives and practices and the consideration of
using knowledge developed outside of their culture are considered.

abstract:
Predicting recruitment is a difficult task and requires solid biological information.
Recruitment in capelin is important to the spawning stock biomass due to a short life
span. Theory predicts that faster growing, larger individuals will have greater survival.
Growth history of two year-classes of Icelandic capelin (Mallotus villosus) larvae was
examined from hatching until end of summer in their first year of life.
Precision of otolith analysis was independent of larval age and growth estimates
were not statistically different between replicates. Estimated growth of 0.37 mm d⁻¹ for
the 2001 year-class was in the upper end of growth rates while growth of the 2002 yearclass,
0.28 mm d⁻¹, was average for capelin larval growth reported in the literature.
Increment width models demonstrated a common growth trajectory both within and
among year-classes. Environmental conditions were better in 2001 as temperature was
higher by roughly 0.7°C and zooplankton biomass was four times greater. This indicates
that better environmental conditions facilitated growth of capelin larvae.
The spawning stock biomass was similar between years but abundance of capelin
larvae in August was three times higher in 2001 suggesting that survival rate of larvae
was higher in 2001. The faster growth and greater abundance of the 2001 year-class
suggests that growth of capelin larvae was density independent.

abstract:
Capelin (Mallotus villosus) is one of the most important commercial fish stocks in
Icelandic waters and a major forage species as important prey for predatory fish, sea birds
and marine mammals. Capelin have adapted to the sub-arctic environment by migrating
north (67-72°N) to feed during summer in deep cold waters (>500m; 1-3°C) before
migrating south (63-65°N) in winter to spawn in warmer shallow waters (<100m; 5-7°C)
on the south and west coasts of Iceland. To examine mechanisms regulating location and
timing of the spawning migration, acoustic recordings were analyzed from cape lin winter
acoustic assessment surveys from thirteen cohorts spawning in 1992-3, 1995, and 1998 to
2007.
The southward capelin spawning migration of all studied cohorts (from 63-67°N)
utilized a consistent route within southward flowing cold sub-arctic waters (l- 3°C) off
the east coast of Iceland. Migration was not passive but active. The route followed the
outer shelf edge but was beyond it (>200m bottom depth). Further south (<65°N), after
the front with warmer Atlantic waters (>4.5°C) was encountered, the migration route
veered inshore (<200m bottom depth) towards coastal spawning grounds.
The annual spawning migration moved southward across latitude 67°N between
December 23 to January 20 in all years. Both an increased spawning biomass and colder
summer feeding temperatures resulted in earlier migration. The migration was not
continuous but staged, with a staging area located offshore in the transition zone between
the offshore and the inshore phase of the migration (63.8-65.8°N). Capelin amassed in
the staging area until roe content reached 12- 14%.
Several mechanisms are involved in the migration. The movement southward
appears to be innate, but the route tracks an offshore thermal corridor until reaching the
Atlantic Ocean front. Capelin then stage in the warmer waters until gonad maturity
reaches a roe content of 12- 14% before moving inshore towards the spawning grounds.
The dependence on temperature suggests that warming temperatures north of Iceland (to
>4.5°C) could result in capelin spawning grounds shifting north as occurred in the
1930's. The extended migration route over deep waters seaward of the shelf edge and the
act of staging may have evolved to minimize the period of spatial overlap with cod (and
hence predation) that occurs on the shelf.

Masters thesis, Memorial University of Newfoundland.

abstract:
This thesis is concerned with three areas of comparison between the short fiction techniques of James Joyce and Sherwood Anderson. The first of these is the brief establishment of a poetics for both authors from their critical and autobiographical writings. Such a process reveals that they each showed a judicious respect for "reality" - or "the fact in nature" as Anderson called it - but significantly they each purified the facts deep down in the forges of their imaginations, and favoured a poetic, suggestive - imaginative - style of writing, in the tradition of the Romantic poets.
The second phase of comparison, and by far the most extensive, covering Chapters II-V, examines the re-created communities of Dublin and Winesburg, Ohio, and especially the individuals in these communities. This scrutiny discloses that the people in both these communities are lonely and frustrated because they are inarticulate, powerless to communicate the forces of their underminds to each other. This inability to speak is also coupled with a lack of community vitality to further isolate the individual. Ultimately, the meaning of life for such people can only come from the inner visions of their imaginations, to find which they must descend into their memories and passions.
Lastly, this search -- and occasional revelation -- determined the kind of short stories that Joyce and Anderson wrote: namely, the plotless, suggestive story of "epiphany," which was a revolutionary form breaking with the action-climax tradition in short story writing. Joyce's and Anderson's contribution to this early twentieth century renovation in short fiction is briefly looked at in the last chapter.
Because writing for Joyce and Anderson meant imaginative re-creation, and because the people they sympathetically re-created lived sordid, unrewarding lives, illuminated only occasionally by visions of the meaning of such existence, it is only natural and proper that their short stories should re-incarnate the searchings of these people in the depths of their minds and the occasional disclosures.

abstract:
This dissertation examines a set of phenomena in Jordanian Arabic (JA) related to the
subject and its position, providing an analysis for each within the assumptions of
generative grammar, particularly those related to the provocative syntax model (Branigan
2010), and functional grammar (Prince 1999, Owens et. al. 2010, among others).
Chapter 2 examines the properties of the preverbal subject and how it is derived.
Based on ambiguity tests involving negation and quantifiers, I show that the preverbal DP
occupies an A position and is derived by movement.
Chapter 3 deals with the embedded lexical subject and the subject clitics that
cooccur with it. I argue that the cooccurrence of a subject clitic and a lexical subject is a
product of a provocation process. Following Branigan (2010), I propose that the C head in
JA is endowed with a provocative feature, which imposes the creation of an external copy
of its internal goal projection. The external copy can be identical or non-identical to the
original goal projection. I take the non-identical shape of a DP projection to be a pronoun
with a deleted NP, in line with the NP-deletion theory (Elbourne 2001 ). Accordingly,
when C locates the preverbal lexical subject as a local goal, it creates an external copy of
it. This copy merges with C, which derives the 'doubling' of an agreeing clitic and the
lexical subject. Since C is provocative, it also has the option to probe for an 'external'
copy that is already available. In this case, C probes for the default clitic -uh. I show that
probing for the default -uh can be obligatory, as in cases where C cannot reach its
internal goal, or optional, where C directly probes for - uh even when with the presence of a 'reachable' internal goal. In this case, we get the 'doubling' of a default clitic and an
overt subject.
Chapter 4 investigates the variation in overt and null subjects within a functional
approach. Specifically, I examine the role of discourse and semantic-pragmatic factors in
overt and null subject variation in JA. I show that the favoring of an overt subject is
influenced by pragmatic anaphora, antecedent salience in the discourse, and predicate
type.

title: Fuel cell simulator system

abstract:
Applied research and development of Fuel Cell (FC) power electronics is
currently expensive and difficult to carry out due to high cost and lack of flexibility of FC
stacks. Flexible affordable FC simulators are required to assist the development and
testing of FC power electronics. Using FC simulators results in significant cost, space,
and time reductions. It also provides a solution for safety standards problems and
overcome the major issue of power sizing in FC stacks. A FC simulator can be
constructed using a power converter that follows a reference signal generated by a FC
model. The output voltage of the power converter is then controlled to behave according
to the FC output characteristics.
This thesis describes in detail the development of two different FC simulator
systems namely, a stand-alone FC simulator based on an empirical model and a low cost
Digital Signal Processor (DSP), and real-time FC simulator based on a small single cell.
A special fast dynamics power converter for FC simulators is designed, taking into
consideration the dynamic requirements to successfully reproduce the behavior of a FC.
A control scheme based on switching surface control is investigated to achieve near time
optimal response in the converter. Laboratory prototypes of the two systems are
implemented and investigated. It is shown that the first system provides the advantages of
eliminating the dependence upon a computer, communication cards, and licensed
software, thus resulting in a small low-cost system suitable for laboratory operation. The
second system overcomes modeling drawbacks and expands the features of the existing
designs by replacing the computer model of the FC with an actual small single FC.
Experimental and simulation results are provided in the thesis to confirm the behavior of
the simulators.

abstract:
Des notre premier contact avec Saint-Exupery, une
idee s'est imposee a nous, que des lectures subsequentes
n' ont jamais dementie: l' evolution se pose comme principe
fondamental a toute la pensee exuperienne. C'est ce que
nous proposons d'expliciter dans cette etude.
Nous etudierons done l'evolution telle que l'entend
Saint- Exupery. C'est une conviction qui s'est imposee a la
suite de ses contacts frequents avec le monde exterieur
que necessite sa vie de pilote. Cette vie, en effet,
requiert une connaissance profonde du monde et des lois
qui le regissent. L'une de ces lois est la marche en avant
de tous les etres et le resultat fatal pour celui qui s'y
refuse.
Dans ce changement perpetual, l'homme occupe une
place toute speciale. Le travail de l'evolution a produit
l'homme. Ce travail se poursuit chez lui dans l'echange
qui n'est rien d'autre que la contribution intelligente et
raisonnee de l'individu au phenomena universel de
l'evolution. c•est a travers cet echange que l'homme
assurera sa permanence.
Si l'evolution et l'echange sont necessites de vie, il va de soi que c'est dans cette direction que nous
devons nous diriger pour vaincre notre angoisse profonde
de mortels. La mort est un vain mot si, par mon travail,
je donne une direction A l'~volution, si, dans mon oeuvre,
je participe a l'~laboration du monde de demain. Ainsi,
paradoxalement, je n'assurerai ma permanence qu'a travers
l'echange, dans mon metier.
Le metier est le moyen pratique par lequel un
individu entre dans la ligne de l'evolution. Certains
metiers s'y pretent davantage puisqu'on peut voir directement
leur effet. D'autres necessitent une prise de conscience
continue de fagon a se rappeler la grande oeuvre
commune. Le travail personnel d'un individu dans le metier
prend une valeur d'eternite quand, a travers les camarades,
on s'y decouvre membre d'une communaute.
A partir de ce moment, la notion primordiale de
responsabilite entre en jeu. Dans sa liberte, l'homme se
voit membre d'une communaute a l'interieur de laquelle
s'etablissent d'innombrables liens. L'individu se doit de
travailler a la direction que prendra la communaute dans
le phenomene total de l'evolution. Il lui faut chercher
les verites qui etabliront justement la cor~nunaute dans la
ligne de l'evolution.
Nous avons parle de verites plutot que de la Verite.
Saint-Exupery ne s'attache pas a une verite objective,
mais aux constatations qu'il peut faire a la suite de ses
experiences. Ainsi, il s'agit plutot d'une marche de
constatation en constatation. Mais il y a progression; les
constatations s'entremelent, se developpent avec la vie,
avec l'homme que l'on entrevoit alors comme devenir .
Pour Saint- Exupery, l'homme, le point culminant
actuel de l'evolution est lui-meme pris dans cet engrenage
et ne s'accomplira pleinement qu'en tant qu'il s•echangera
centre plus grand que soi. Fidele au dynamisme qui l'a

abstract:
One means whereby the mammalian kidney excretes strong acid is by
the formation of neutral ammonium salts in the urine. In response to
a continuous acid challenge, the rate of ammonia excretion increases to
meet the increased acid load. In the present study a strong acid load
was administered to rats for 7 days, Ammonia excretion increased slowly
reaching plateau levels after about three days. After the acid challenge
was discontinued, the rats were placed back on tap water and allowed to
recover. Ammonia excretion abruptly fell to normal within 24 hours.
Phosphate dependent glutaminase (PDG) activity, the penetration of
glutamine into mitochondria (the site of PDG) and phosphoenolpyruvate
carboxykinase (PEPCK) activity have all been considered as rate-determining
for the renal production of ammonia. For this reason the activities of
PDG and PEPCK were measured in vitro during adaptation and recovery.
Also glutamine metabolism (ammonia production and oxygen consumption)
and the metabolism (oxygen consumption) of related substrates (glutamate,
a-ketoglutarate and succinate) by isolated kidney cortex mitochondria
were followed . In addition, glutamine metabolism (glutamine utilization,
ammonia production, glutamate formation and glucose production) and the
metabolism (glucose production) of related substrates (oxaloacetate,
malate, lactate and pyruvate) by kidney cortex slices were measured during
recovery. Mitochondrial capacity (PDG activity, oxygen consumption and
ammonia production from glutamine) appears to correlate with the excretion
of ammonia in the urine during adaptation. This correlation is consistent
with ammonia production being regulated by a mitochondrial event. PEPCK
attained maximum activity in vitro 24 hours before ammonia excretion reached its plateau. This suggests that the amount of PEPCK is not ratedetermining
during adaptation. During recovery mitochondrial capacity
remained at high plateau levels whereas the activity of PEPCK in vitro
fell to normal values within 24 hours, The lack of a correlation between
mitochondrial capacity and urine ammonia excretion suggests that renal
ammonia production is not regulated solely by a mitochondrial event
during recovery. No change in the mitochondrial metabolism of glutamate,
a-ketoglutarate or succinate was observed during either adaptation or
recovery. The remarkable correlation found during recovery between
PEPCK activity in vitro, the metabolism of glutamine and related substrates
by kidney cortex slices, and urinary ammonia excretion is consistent
with PEPCK playing a regulatory role in ammonia production during
this phase. Glutamine arteria-renal venous differences were also
measured during adaptation and recovery and at all times paralleled the
rate of ammonia excretion in the urine. Blood pH, [HCO)-₃, and pCO₂
were followed to help assess their possible regulatory significance. No
simple correlation appears to exist between any of these parameters and
urinary ammonia excretion.
Rats recovering from 7 days of acid challenge were also starved.
During this starved recovery PEPCK decreased slightly but remained
elevated, yet ammonia excretion returned to normal. This dissociation is
not consistent with this enzyme alone being regulatory for ammonia production.
Rats were also returned to tap water after only 3 days of acid
challenge. In comparison to recovery from 7 days of acid challenge
urinary ammonia excretion persisted for an additional 24 hours. Since the acid~base status of the animal was shown to improve only after ammonia
excretion had been fully adapted ~or some t~me~ then the persistence of
elevated ammonia excretion supports the idea that the excretion of ammonia
during recovery is related to restoration of acid-base balance.

Doctoral (PhD) thesis, Memorial University of Newfoundland.

abstract:
We initially assessed the characteristics of stroke development in Dahl salt-sensitive
rats (Dahl-SS). Dahl-SS developed high blood pressure (BP) when fed
a high salt diet (8.7% NaCl) from weaning and a 50% mortality after being fed the
diet for 4 to 5 weeks. Prior to death, Dahl-SS exhibited behavioural symptoms
(convulsions, seizures, paralysis and stupor) consistent with the possible
development of stroke. However, unlike true stroke, the behavioural
dysfunctions observed were not associated with cerebral ischemia and occurred
in the virtual absence of cerebral hemorrhage. An investigation of the
cerebrovascular pathology indicated a breakdown in the integrity of the blood
brain barrier and fluid movement into the extravascular space (edema). It was
concluded that Dahl-SS best represents a model of hypertensive encephalopathy
(HE). In humans HE is produced by brain edema as a result of hypertension in
the absence of cerebral ischemia or hemorrhage. It produces convulsions,
confusion, and stupor and can result in death. The latter symptoms are
consistent with those observed in Dahl-SS fed high salt.
Antihypertensive intervention (captopril) was ineffective in lowering blood
pressure or reducing the incidence of mortality. Non-cerebral organ failure was
also evident prior to death as demonstrated by kidney dysfunction associated
with increased plasma creatinine, urea, urinary protein excretion and decreased
plasma albumin levels.
In subsequent experiments we tested the hypothesis that a breakdown in
the ability to autoregulate cerebral blood flow (CBF) may contribute to the
development of HE in Dahl-SS fed high salt. Such a defect could promote
cerebrovascular overperfusion and elevate microvascular blood pressure,
alterations that would facilitate blood brain barrier disruption and HE
development. Laser Doppler techniques were used to assess the changes in
relative CBF with varying BP in the perfusion domain of the middle cerebral
arteries (MCA's). Dahl-SS fed 8.7% NaCl for 1 week exhibited an ability to
autoregulate near constant CBF up to an upper mean BP of 168 mmHg. Two
thirds of the rats lost the ability to autoregulate CBF after they were fed a high
salt diet: for 3 weeks at a time prior to the development of HE. These rats
exhibited a linear increase in CBF with elevations in arterial pressure. The
characteristics of the CBF autoregulatory curves suggested that CBF
autoregulation was lost under conditions of cerebrovascular constriction.
In other experiments we assessed the hypothesis that the loss of CBF
autoregulation in the MCA perfusion domain of Dahl-SS was associated with an
inability of the MCA's to elicit pressure dependent constriction (PDC). PDC is an
important mechanism involved in promoting CBF autoregulation. Elevations in
BP promote cerebrovascular constriction, which raises vascular resistance to
blood flow. This counteracts the potential elevation in CBF enabling CBF to
remain constant under conditions of elevated BP. Isolated MCA's from
asymptomatic Dahl-SS exhibited constriction in response to elevated pressure and protein kinase (PKC) activation (a signaling intermediate for PDC in MCA's).
In addition the MCA's vasodilated in an endothelium dependent manner in
response to bradykinin. These functions were lost in the MCA's of Dahl-SS with
HE. MCA's from post-HE Dahl-SS that were unable to constrict to pressure
lacked the ability to constrict in response to PKC activation via phorbol esters.
They exhibited high levels of basal tone and no response to the endothelial
specific vasodilator, bradykinin. The loss of PDC in MCA's of Dahl-SS preceded
the development of HE and occurred in asymptomatic rats fed high salt for 3
weeks at a time when CBF autoregulation was lost.
It was concluded that defects in the ability of the cerebrovasculature to
autoregulate CBF in conjunction with the development of renal dysfunction could
contribute to the development of HE in Dahl-SS fed high salt. Cerebrovascular
PDC is thought to play an important role in facilitating CBF autoregulation. The
loss of this function could contribute to a loss of CBF autoregulation under
hypertensive conditions. This could increase cerebrovascular pressures and
promote overperfusion in the brain, leading to the development of cerebral
edema and HE. The development of HE could be further augmented by a
decrease in plasma oncotic pressure promoted by the loss of plasma proteins
due to the occurrence of proteinuria. The presence of a dysfunctional PKC
system in the vascular smooth muscle of MCA's sampled from Dahl-SS with HE
could contribute to the loss of PDC in the arteries.

L'objectif de ce mémoire est de montrer l'évolution de certains personnages
hébertiens concernant le manque d'une figure maternelle. Apres avoir refoulé le passé,
chaque personnage reconnalt ce manque d'une présence maternelle et il doit réussir a
venir à bout de ce vide dans sa vie. Les quatre textes hébertiens suivants sont analysés
dans ce mémoire: Heloïse, Les Fous de Bassan, Le Premier Jardin et Est-ce que Jete
dérange ? Ces quatre textes, qui s'étendent sur une vingtaine d'années, montrent au
lecteur des ressemblances et, en meme temps, des différences entre les relations a la mere
de chaque personnage.
Tous les personnages qui sont analysés commencent a la meme étape : une figure
maternelle leur a été dérobée. Ces personnages refoulent le secret lié a leur enfance
misérable. C'est le moyen de se charger de cette tache qui differe d'un personnage a
l'autre. Par exemple, Flora Fontanges, personnage principal dans Le Premier Jardin, est
en deuil d'une vraie mere depuis sa naissance. Flora se rend compte elle-meme de la
source de sa propre douleur en revisitant Québec, sa ville natale, et elle affronte les
souvenirs de son enfance traumatisante. Edouard, le protagoniste dans Est-ce que Je te
dérange ? se sent détaché de sa mere depuis son enfance. Sa vraie mere, la cause de sa
souffrance, est morte, et on verra qu 'Edouard reussira a affronter la source de ses
traumatismes. Stevens Brown et Nicolas Brown dans Les Fous de Bassan souffrent aussi
d'une absence maternelle des leur enfance, mais ils suivent un chemin different pour
remplir le vide laisse par la mere : ils décideat de detruire tout ce qui est lie a la
maternite, y compris les femmes qui jouissent de relations chaleureuses avec les figures maternelles dans leur vie. Quant à Bernard, le protagoniste dans le roman Héloïse, il se
sépare inconsciemment du monde réel parce qu'il ne veut plus souffrir du manque d'une
figure maternelle qui contrôlerait sa vie.
Certains personnages principaux etudies dans ce memoire reussissent a retrouver
la tendresse maternelle ou a faire face a leurs souvenirs douloureux, mais i1 y en a
d'autres qui ne retrouverontjamais leur premier jardin, le lieu symbolique ou le rapport
essentiel entre mere et enfant se developpe.

Masters thesis, Memorial University of Newfoundland.

abstract:
Substantial decrements in upper limb manual performance are evident
following cooling of the upper limb in humans. In this thesis 2 studies were
conducted to observe if gender (Study 1) or 5 days acclimation (Study 2) affected
upper limb manual performance, strength and perceived pain and comfort both during
and following whole arm immersion in 8°C water. Performance and strength tests
plus pain and comfort ratings of 6 males and 6 females were compared in Study 1 and
six males in Study 2 were compared for the same tests and ratings on Day 1 and Day
5 of repeated whole arm 8°C immersions. Study 1 showed no significant difference in
muscle (T mus) or skin temperature (Tsk) across gender. Relative to males, the females
had significantly faster finger flexion and extension times (p=0.03), better peg and
ring test performance during rewarming (p<0.05) and significantly lower maze
tracking error rates (O.OOS < p < 0.02). Comfort and pain ratings across gender were
affected to a similar extent by cold immersion. In Study 2 during the 5-day
acclimation, Tmus followed the same profile on days 1 and 5 of immersion. A
significant Day by Time interaction (p=0.04) was evident for Tsk and the interaction
was explained by significantly higher Tsk on Day 5 versus Day I prior to (p=0.002)
and following immersion (0.01 < p < 0.02). The 5-day acclimation gave a trend for (p
= 0.07) faster finger extension and flexion times. Grip strength adjusted to preimmersion
values was significantly improved (p =0.006) by acclimation. As well
perceived pain was significantly lower (p < 0.05) and comfort was significantly higher (p < 0.05) during initial 20 min of limb immersion after 5 days of cold limb
acclimation. In conclusion, with upper limb cooling females showed limited
evidence of better manual performance relative to males for some fine and gross
motor tasks. Five days of acclimation gave significant improvements in skin
perfusion, as indexed by skin temperature, grip strength and cold perception during
the initial immersion. Acclimation gave only trends for better performance on fine
and gross motor tasks.

abstract:
Prior to 1890, the British in India had made very little contact
with the Tibetan people but during the two decades which followed the
British made many attempts to establish and improve their relations
with the Tibetans. It is the aim of this thesis to contribute some
historical insight into certain political and economic problems which
were shared by both the British in India and the Tibetans between the
years 1890 and 1914.
In the first chapter the geography of northern India and Tibet
is discussed with particular reference to the main routes leading from
India into Tibet. Also in this first chapter some consideration is
given to the social background of the Tibetan people. The second
chapter consists of a brief historical summary of the people of Tibet.
Both of these introductory chapters serve background to that period
of time under analysis, namely; the twenty-four years spanning the turn
of the present century.
The main body of the thesis is divided chronologically into six
chapters which are based on the international agreements relating to
India and Tibet which were signed between 1890 and 1914. In considering
the causes and results of these agreements, many interconnected problems
arise, among which two of the most significant are the relative importance
of the political and economic motivation behind the British penetration
into Tibet and a consideration of the international status of Tibet.
Moreover, each chapter deals with the efforts of the British to establish
efficient and consistent connections with Tibet from the time when
practically no relations existed up to the time when such relations became
relatively formulated and stabilized.

Masters thesis, Memorial University of Newfoundland.

abstract:
Effects of a recent wildfire in the lichen-black spruce woodland in Terra Nova
National Park, Newfoundland, were investigated to determine the interaction between fire
intensity and fire severity; plus effects on forest-floor disturbance, on canopy seed banks,
and on black spruce regeneration. As there was much exposed mineral soil from ant
activity on this site, the potential for enhanced post-fire black spruce recruitment due to
ants was also investigated. A seeding trial considered four potential seedbeds available:
areas of high severity; areas of low severity; active ant nests; and abandoned ant nests. In
addition, the amount and distribution of seed rain in the burned area was measured in an
attempt to assess factors that affect the pattern and success of black spruce recruitment
following fire. Duff depths were reduced by fire by as much as 50% while lichen depth
by up to 88%. Ant nests occurred at a density of 6.15 per 100m² in the burned areas
compared to 2 per 100m² in the unburned forest. Black spruce seed-fall, while low at 16 539 seeds per ha in the year following the fire, was sufficient for re-establishing the lowdensity
lichen woodland community at an initial density of 524 seedlings per ha by 2003.
However, a mean cone removal of 52% by non-native red squirrels may be limiting the
establishment of a higher-density forest. Available seedbed was limited by the extensive
caribou-lichen mat, but over 40% of successful black spruce seedlings in the seeding trial
germinated in this substrate, compared with 33% for inactive ant nests and 26% for high
severity bum. Seedlings were most likely to become established and survive in
desiccation fractures in the lichen mat. The presence of abandoned ant nests did result in
germination, but did not necessarily result in establishment as seedling survival was
reduced from 89% to 44% after winter. Seedling mortality on scorched organic soil
substrate under former spruce canopies was highest at 71 %. Active ant nests produced no
germinants in the trial and were the least suitable for germination. Drier and warmer than
normal conditions in 2003, resulting in soil moisture deficits, appeared to be the main
limiting factor for black spruce germination and survival. The next several years will be
critical for subsequent black spruce germination and survival and in determining if reestablishment
of the recently burned lichen woodland in TNNP will be successful.

abstract:
Historical changes in predator composition in the Newfoundland ecosystem as a result of
over-fishing have resulted in a switch from a cod-dominated system to one with abundant
decapod crustaceans. In order to understand the consequences of this switch to benthic
ecosystems, it is critical to evaluate how epifaunal crustaceans regulate sedimentary
communities. An array of exploratory and experimental studies was undertaken in Bonne
Bay, a sub-arctic Newfoundland fjord, in order to document predator and prey spatial
variation and community responses to predator manipulation.
The distribution of snow crab and at least one shrimp species in the main arms of Bonne
Bay fjord were found to be related to planktonic larval supply, particularly, late larval
stages. The distribution of infaunal prey varied in parallel with predator patterns and, as
shown by detailed analysis of the dominant taxon (polychaetes), was related to habitat
quality and distribution. Sandy and muddy habitats supported different infaunal
communities, and species that occupied a variety of substrates were more broadly
distributed inside the fjord and the region. Field exclusion and inclusion experiments
carried out in the two main arms of the fjord were complemented with laboratory
experiments using the main predators of the fjord: snow crab (Chionoecetes opilio), rock
crab (Cancer irroratus) and toad crab (Hyas spp). Results suggest that i) crustacean
predation regulates benthic composition, density, and sometimes diversity, ii) predator
effects vary spatially, iii) the same infaunal species were important in describing predator exclusion treatments both in the field and in the laboratory experiments, and iv) snow
crab and rock crab are the predators that have the strongest effects on infaunal
communities. Given that both predators are targeted by the fishery, these results also
suggest that the potential impacts of fishing may be even broader than expected through
cascading effects on infauna. Finally, the effects of predation on benthic infauna were
examined using surrogates or taxonomic categories coarser than species. Although results
obtained with data at the family level resemble those with data at the species level, the
lack of generality in surrogate performance suggests a cautious use of surrogates in
experimental and biodiversity studies.

abstract:
Lipid dispersions with planar regions enriched in long chain lipids and highly curved
regions enriched in short chain lipids can exhibit complex phase behaviour. Such
"bicellar" mixtures provide insight into how the morphology of self-assembled soft
structures are determined by component heterogeneity. Bicellar dispersion propert
ies can be affected both by surface charge and the application of pressure. Variable
pressure deuterium nuclear magnetic resonance (²H NMR) studies were carried
out on bicellar lipid mixtures comprising t he short chain lipid 1,2-dihexanoyl- snglycero-
3-phosphocholine (DHPC), the long chain lipid 1 ,2-dimyristoyl-sn-glycero-3-
phosphocholine (DMPC) and the anionic lipid 1,2-dimyristoyl-sn-glycero-3-phospho(
1'-rae-glycerol) (sodium salt) (DMPG). Samples of DMPC-d₅₄ / DMPG/ DHPC (3 :1:1 ),
DMPC/DMPG-d₅₄ / DHPC (3: 1:1) and , for comparison, DMPC-d₅₄ / DHPC (4:1) were
prepared and hydrated in HEPES buffer at lipid weight fractions of 10%. DMPCd₅₄
/ DMPG/ DHPC (3:1:1) sample was also prepared with the same sample preparation
protocol but the sonication and freeze-thaw omitted . Spectra and quadrupole
echo decays were obtained, between 4⁰c and 65⁰c, for both warming and cooling at
ambient pressure, 41.4 Mpa, and 82.7 Mpa. At ambient pressure, all mixtures form
isotropically reorienting small particles at low temperature. On warming past the
DlVIPC gel-to-liquid crystal transition temperature, the particles coalesce into larger
structures that can be magnetically oriented. At higher temperatures, the dispersions form more randomly oriented lamellar phases. On cooling at ambient pressure,
the lamellar phase persists to lower temperature where it transforms directly
to the isotropic phase. Application of pressure raises the transition temperatures
for DMPC-d₅₄ / DHPC (4:1) but does not significantly change the phases observed.
For DMPC-d₅₄ / DMPG/DHPC (3:1:1), pressure can stabilize the isotropically reorienting
phase to higher temperature on warming. On cooling under pressure, DMPCd₅₄
/ DMPG/ DHPC (3:1:1) can reorganize into a highly ordered gel phase with spectra
similar to those of the high pressure interdigitated gel phases of some phospholipids.
The same phase behavior was observed for non-sonicated DMPC-d₅₄ / DlVIPG/DHPC
(3:1:1) and for DMPC/ DMPG-d₅₄/DHPC (3:1:1). Once nucleated, the highly ordered
gel phase appears to be stable even at ambient pressure. These observations
demonstrate the sensitivity of dispersion morphology to details of mixed-lipid sample's
thermal and pressure history.

title: The novels of Robert Louis Stevenson

abstract:
Stevenson first entered fiction in the romantic
novel of action, more specifically the boys' adventure
story. Treasure Island is handled skilfully both in
development and style, and, while The Black Arrow is somewhat
inferior, Kidnapped· is again of the calibre of the first
book. Although it is an adventure story, plot and character
developments in Kidnapped, which occur when Stevenson introduces
the elements of Scottish history and topography, suggest the
later dramatic novels.
The triumph of evil, a dominant theme, is treated
most vividly in Dr, Jekyll and Mr, Hyde and the Master of
Ballantrae. Concurrent with this theme is the presentation
of 'The Devil as Angel' in Silver, Alan Breck, James Durie
and Frank Innes. Moreover, these two novels mark the transition
from romantic to dramatic. Although the characters are still
flat, Jekyll and Henry Durie do make moral choices which
determine their destinies. In The Master of Ballantrae,
also, is the father-son estrangement and the integration of
the Scottish national character as background for the psychological
situation.
In conception and execution Weir of Hermiston is
magnificent, and Stevenson's greatest novel. Here, once
more, is the father-son relationship, set against the
Scottish background. But Weir of Hermiston is also a great love story.
The quality of Weir of Hermiston and Stevenson's
perspicacity as a critic suggest he consciously produced
inferior work. While a harsh judgement of this should be
tempered by consideration of his physical disability, the
weaknesses in his novels force him, certainly not into
oblivion, but at least into the second class.

abstract:
The Hittite -ḫi conjugation is acknowledged to be one of the most enigmatic of Indo-European formations. Despite its link to the Indo-European perfect, attempts to establish the
extent and nature of this relationship have met with serious difficulties. In this thesis, I argue
that the -mi/-ḫi conjugations represent a vestige of an earlier Indo-European binary system
and the original voice opposition in Hittite, with other voice-related developments, including
the "medio-passive" in -rand the "reflexive" particle -z(a) secondary and/or increasing as
the original diathesis became obsolete.
Volume I discusses the morphological, phonological and semantic factors which
distinguish the two Hittite conjugations. Adopting Lehmann's (2002) terminology, I identify
the -ḫi conjugation as the centripetal member of the opposition and the -mi as centrifugal.
The former is distinguished by its orientation to the self--a direct parallel to Sanskrit
atmanepada voice ('word for self') vs. parasmaipada voice ('word for another'). Higher
self-involvement is the essential characteristic of middle voice as traditionally defined (Lyons
1969, Barber 1975, Klaiman 1991 and Kemmer 1993).
I present argument and evidence that the inflectional elements which mark the Hittite
opposition most clearly in the first person singular represent different cases of first person
pronominal stems cliticized to the verb: direct case -ḫ (centripetal voice) and oblique case
-m (centrifugal voice). These grammaticalized elements are identical in origin to the independent pronouns of IE. Two factors unique to Hittite allow me to make this argument:
the existence of laryngeal phonemes and the presence of nominative-case clitics
Volume II focusses on 132 clearly attested Hittite -bi verbs. I motivate the allocation
of this group of verbs to 'high-self-involvement-type' by illustrating their social, cultural and
intellectual centrality both in Hittite and IE culture. I refer to criteria set out in Kemmer' s
1993 study of middle voice to show that the majority of -bi verbs fall clearly within the
semantic range of this type of verb. I provide evidence of morphological similarity of -ḫi
verbs to the IE perfect, including o-grade, ablaut patterns and archaic stative morphology (in
-e ), as well as semantic parallels to media tantum, deponent or middle-marked verbs in other
IE languages.

title: Wavelet modulated DC-AC power inverters

abstract:
Modern industrial applications of dc-ac inverters have increasing demands for high quality output voltages and currents. Such demands are met through  operating inverters so that output harmonic components are either reduced or eliminated. Developing and testing switching strategies capable of achieving such outputs have been topics for intensive research for the last 4 decades. Several switching strategies realized by modulation techniques have been proposed and tested. As a result, significant contributions on the performance of inverters have been achieved. However, the problem of output harmonic components is still a challenge. One of the most critical limitations of existing modulation techniques is the lack of correlation between these techniques and any inverter models.
An inverter can be modeled as a non-uniform recurrent sampling reconstruction process,  in which instantaneous switching actions are considered as the reconstruction inverter outputs. This modeling approach can also be employed to verify the effects on inverter outputs due to any changes in the switching strategy. Using the concepts of the sampling theorem, a sampling-reconstruction process is represented as a multiresolution analysis (MRA). Effective and accurate MRAs can be constructed using basis functions generated by scaling and wavelet functions. A modulation technique that incorporates the proposed sampling-based inverter model and a wavelet -based MRA can enable the operation of inverters for high quality outputs. The development, implementation and testing of such a modulation technique is the primary objective of this research.
A novel approach to construct a non-dyadic type MRA that is capable of supporting non-uniform recurrent sampling has been  developed.  The non-dyadic type MRA is developed based on new scale-based linearly-combined scaling and
wavelet functions. The reference-modulating signal is sampled using the new scaling function such that a number of sample groups are formed over each cycle of the reference-modulating signal. Each group has two samples that are created by a dilated and translated version of the scaling function. Reconstructing the reference modulating signal is carried out by stages of interpolating functions, where each stage is defined over one sample group. This structure of interpolating functions creates one ON switching pulse over each sample group. The approach of operating the inverter aims to concentrate the energy of the output signal in the frequency of the reference-modulating signal. As a result, negligible energy is distributed in the rest of frequency components.
The proposed wavelet modulation technique is implemented using an algorithm for both simulation and experimental testing. The results of both simulations and on-line tests show high quality output voltages and currents indicated by the low values of total harmonic distortion factors. These tests are conducted for different load types under several output frequencies. Also, a new control strategy is developed for adjusting magnitudes and frequencies of wavelet-modulated inverter outputs. This control strategy is called resolution-level control, and is based on changing the scale of the successive reconstruction functions. Simulation and experimental test results of a dc-ac inverter under this control approach demonstrate stable, robust and fast responses for different load changes. The developed non dyadic type MRA is extended to operate three-phase inverters. An algorithm is developed for simulation and experimental tests of the three-phase wavelet modulated inverter to supply a R - L load. Results obtained from these tests have demonstrated high quality outputs with negligible harmonic contents.

abstract:
Mammalian lungs are composed of millions of tiny air sacs called alveoli where gas
exchange takes place. The inner surface of alveoli is coated by an aqueous layer to
prevent it from drying up. However, because the attraction between water molecules is
stronger than the force between water and air, a surface tension is created at the air-water
interface. The tension tends to collapse the alveoli and increase the work of breathing.
Lung surfactant is a material that counteracts these tendencies by reducing the surface
tension to extremely low values and thus prevents the alveolar collapse and also eases the
work of breathing. The lung surfactant material is a mixture of lipids and proteins.
Surfactant Protein B (SP-B) is an essential component of the surfactant and is thought to
function by facilitating large-scale rearrangement of the lipid molecules and stabilizing
the structures. However, neither the structural basis for this ability nor the physiological
ramifications of lipid rearrangements are yet understood. SP-B is a lipid-associated
hydrophobic protein, which makes it difficult to address with X-ray or conventional
solution NMR structural techniques. These difficulties have been addressed in NMR
structural studies by the use of fluorinated organic solvents and lipid micelles to
solubilize the proteins. The present work has focused on SP-BcTERM and Mini-B, two
peptide fragments of SP-B that retain significant biological activity of the full-length
protein. The structural features of these peptides were studied using high-resolution
solution NMR. Firstly, the conformational features of SP-BcTERM and its interactions with
lipids were investigated in micelles mimicking the lipid environment in the lungs. The
peptide exhibited the ability to cause aggregation of micelles formed from lipids similar
to those found in lungs. This was indicative of the large-scale lipid rearrangement and
stabilization of structures facilitated by SP-B in natural surfactant. In the second and main
phase of current research, the structure of Mini-B was determined in the structureinducing
fluorinated organic solvent hexafluoroisopropanol (HFIP). The peptide was
found to consist of two a-helices at the termini connected by an unstructured loop at the
middle. These studies help to define the structural properties that underlie SP-B's
function and provide a platform to probe the lipid-protein interactions that are responsible
for the ability of lung surfactant to dramatically lower the surface tension at the air-water
interface in alveoli.

abstract:
The composition of several objects to one higher-level, composite object is a central
technique in the construction of object-oriented software systems and for the management
of their structural and dynamic complexity. Standard object-oriented programming
languages, however, focus their support on the elementary objects and on class
inheritance (the other central technique). They do not provide for the expression of
objects' composition, and do not ensure any kind of encapsulation of composite objects.
In particular, there is no guarantee that composite objects control the changes
of their own state (state encapsulation).
We propose to advance software quality by new program annotations that document
the design with respect to object composition and, based on them, new static
checks that exclude designs violating the encapsulation of composite objects' state.
No significant restrictions are imposed on the composite objects' internal structure
and dynamic construction. Common design patterns like Iterators and Abstract Factories
are supported.
We extend a subset of the Java language by mode annotations at all types of object
references, and a user-specified classification of all methods into potentially state changing
mutators and read-only observers. The modes superimpose composition
relationships between objects connected by paths of references at run-time. The
proposed mode system limits, orthogonally to the type system, the invocation of
mutator methods (depending on the mode of the reference to the receiver object),
the permissibility of reference passing (as parameter or result), and the compatibility
between references of different modes. These restrictions statically guarantee state
encapsulation relative to the mode-expressed object composition structure.

Masters thesis, Memorial University of Newfoundland.

abstract:
This thesis had three major objectives: 1) to determine the most appropriate
method for the short-term storage of blubber biopsy samples for hormonal analyses, 2) to
determine whether or not progesterone could be quantified in blubber biopsy samples
from free-ranging North Atlantic humpback (Megaptera novaeangliae) and North
Atlantic right (Eubalaena glacialis) whales in order to determine pregnancy status, and 3)
to determine whether or not immunoassayable progesterone could be quantified in ancient
whale bone samples.
In order to determine the most appropriate method for storing blubber biopsies for
hormone analyses, samples were collected from a known pregnant minke whale
(Balaenoptera acutostratus) post-mortem and stored frozen for 2 months under different
conditions- in ethanol, 100% dimethylsulfoxide (DMSO), 20% salt-saturated DMSO,
and frozen. Biopsy samples stored in ethanol yielded less than 10% of the progesterone
concentrations of those in the other three storage conditions (p < 0.05). However, once
extracts of both the blubber samples that were in ethanol and the ethanol liquid fractions
were combined, progesterone concentrations were comparable to those of the other three
storage conditions (p > 0.05).
Progesterone concentrations were determined from blubber biopsy samples of
free-ranging humpback (n = 32) and right (n = 17) whales in order to determine
pregnancy status. We hypothesized that females pregnant at the time of sampling would
have elevated blubber progesterone concentrations.
Thirteen of 21 female humpbacks (62%) were resighted the year following
sampling. Three females with elevated blubber progesterone concentrations and one with a moderate progesterone concentration were observed with calves. Seven mature females
(two with elevated blubber progesterone concentrations and four with moderate blubber
progesterone concentrations) were observed without calves, introducing the possibility of
neonatal mortality, spontaneous abortion, pseudopregnancy, or possibly failure of the
technique. Two females that had blubber progesterone concentrations comparable to
males and immature whales were observed without calves. All adult males and immature
individuals had low blubber progesterone concentrations.
All right whales, with the exception of one, were resighted following sampling.
One mature female with an elevated blubber progesterone concentration was observed
with a calf approximately six months following sampling. One mature female with a
moderate blubber progesterone concentration was observed on the calving ground
numerous times four to seven months after sampling but without a calf introducing the
possibility of pseudopregnancy, spontaneous abortion, or neonatal mortality. All adult
males and juveniles of both sexes had relatively lower blubber progesterone
concentrations.
Progesterone concentrations were measured in ancient bone samples from
bowhead (Balaena mysticetus) and right whales killed in the 16ᵀᴴ century Basque fishery
in Labrador. Immunoassayable bone progesterone concentrations from 0.19- 13.07 ng/g.
were detected. Bone progesterone concentrations of samples taken from bones that were
known to have been underwater until relatively recently were significantly greater than
those from bone samples collected in terrestrial deposits (p < 0.05). Reproductive status
could not be determined on the basis of progesterone concentrations alone, and a
preliminary analysis awaits the determination of sex for each of the samples.

abstract:
A novel Xenopus gene called Xrel3 has been recently described, which encodes a member
of the Rel/NF-κB family of transcriptional activators (Yang et al., 1998; Lake et al.,
2001). Xrel3 mRNA is expressed during early cleavage stages, followed by a dramatic
decline to undetectable levels at gastrulation. Later in development, messages localize to
the prospective forebrain, dorsal mid-hindbrain, notochord, and otocyst. Overexpression
of Xrel3 by microinjecting synthetic RNA into two-cell stage embryo in the animal pole
region causes embryos to develop abnormal growths, or tumours (Yang et al., 1998).
Ectopic expression of Xrel3 seems to have a major effect on pre-gastrula development.
Overexpressed in the dorsal region of the embryo it caused a reduction in dorsoanterior
structures in embryos, with a majority of embryos having small heads, kinked backs and
shortened tails. Most of them failed to initiate gastrulation movements, as compared to
controls. When animal caps from embryos injected with Xrel3 were treated with
XTC-CM, Xrel3 reduces activin-induced elongation of animal caps. Xrel3, however, does
not reduce FGf-mediated induction of animal caps, or the expression of Xbra in FGF-treated
embryos. The results presented here show that Xrel3 inhibits mesoderm induction,
but not by interfering with bFGF pathway, but by regulating activin A signalling.

Masters thesis, Memorial University of Newfoundland.

abstract:
Mafic-to-felsic intrusive rocks of the Horse Cove Complex have been mapped in
detail in the area surrounding Bauline on the east coast of Conception Bay in the Avalon
Zone, Newfoundland. The Horse Cove Complex is characterized by a swarm of mafic-to-
felsic dykes that coincide with the extrapolated trace of the Topsail Fault along the east
coast of Conception Bay and are hosted by mafic submarine volcanic rocks and, locally,
by diorite. In the Bauline area, the Horse Cove Complex is hosted by granodiorite, which
has been dated at 625 ± 1.5 Ma using U/Pb zircon geochronology with the chemical
abrasion thermal ionization mass spectrometry (CA-TIMS) method. This granodiorite is
correlative to the felsic plutonic rocks of the Holyrood and White Hills intrusive suites,
located south of Bauline, within and along the eastern margin of the Holyrood Horst.
Based on detailed mapping and petrography in the Bauline area, the Horse Cove Complex
has been divided into ten rock units. These rocks units include: feldspar porphyry, gabbro
and diorite, which are the host rocks to the dyke swarm, and eight rock units that
represent dykes of mafic-to-felsic composition. The Horse Cove Complex has been
affected by greenschist-facies metamorphism, resulting in partial replacement of igneous
mineral assemblages by greenschist-facies minerals, but igneous minerals and textures are
still recognizable. The age of magmatism in the Horse Cove Complex has been bracketed
by CA-TIMS U/Pb zircon ages of feldspar porphyry (580.6 ± 2.0 Ma) and an andesitic
dyke (578.4 ± 2.3 Ma). Since field relationships indicate that these rock units represent
the oldest and youngest datable rocks in the Complex, magmatism occurred over a period
of 6.5 Ma or less: from 582.6 to 576.1 Ma, at maximum age limits. This age of magmatism overlaps, within uncertainties, with several magmatic events on the NE
A val on Peninsula, including felsic volcanic and fine-grained intrusive rocks along the
eastern margin of the Holyrood Horst and near Cape St. Francis. Based on
lithogeochemistry, feldspar porphyry and rhyolitic dykes in the Horse Cove Complex
appear to represent volcanic arc magmatism and may be co-magmatic. The mafic to
intermediate dykes and host rocks in the Horse Cove Complex are comprised of calc-alkaline
and tholeiitic rocks that exhibit a range of compositions, from rocks with EM
ORB-like geochemistry to rocks that are LREE-enriched and have negative Nb
anomalies, con1parable to subduction-related calc-alkaline basalts and andesites. There is
an overall progression from rocks with E-MORB-like geochemistry to rocks with arc
signatures, but exceptions exist due to the episodic emplacement and complex crosscutting
relationships of the dyke swarm. Seven rocks from the Horse Cove Complex,
including a rhyolitic dyke and several mafic-to-intermediate rocks, have εNd values (at
580 Ma) ranging from +4.1 to +6.4. Thus, these rocks appear to have depleted mantle
sources that have undergone various degrees of mixing or assimilation with older, LREEenriched
sources, such as continental crust and/or sediments in a subduction zone. The
interpreted paleo-tectonic setting of the Horse Cove Complex is a back-arc basin
environment, in which rocks with LREE-enriched mantle sources and subductioncontaminated
sources were emplaced side-by-side and closely in time. The Horse Cove
Complex may represent the last phase of subduction-related magmatism in the eastern
Avalon Zone in Newfoundland prior to deep marine, deltaic and alluvial fan
sedimentation during the late Neoproterozoic.

abstract:
Clode Sound is a small fjord on the east coast of Newfoundland that contains a
shallow sill and coinciding contraction. Studies of the hydrographic properties and
currents in Clode Sound, Newfoundland during the summers of 1996 and 1997 indicate
that considered as a two-layered model the tidally forced flow over the sill is supercritical
during spring tides. Supercritical flow may lead to the formation of internal bores or
internal hydraulic jumps that increase the vertical mixing as they propagate away from
seaward side of the sill. Within the inner basin, there is little evidence of mixing below
the level of the sill and the inner basin water, formed during the winter months, remains
trapped. Fresh water inflow from the Northwest River is low but the combination of
mixing and the input of solar radiation leads to the formation of a well-defined surface
layer in which the water column is thermally stratified. On the seaward side of the sill,
the surface layer extends below the level of the sill, within the inner basin the depth of the
surface layer is limited by the depth of the sill.
The model used to simulate the circulation of Clode Sound is based upon the
Princeton Ocean Model (POM). Attempts to simulate the three-dimensional circulation
using a static density field reveal that such a model is not capable of reproducing the tidal
currents with Clode Sound. Models with a static density field show no significant
difference to a model with constant density. The inability of the model to reproduce the
tides leads to an imbalance of forces when wind stress is applied to the model. Further
simulations in which temperature and salinity evolve within the model provide a much
better result for the main tidal constituents. The inclusion of temperature and salinity
mixing required very strong relaxation of the scalar fields and the model performance is evaluated with both a constant background density field and an evolving background
density field. Wind stress applied to the mixing model leads to the rapid onset of
numerical instability limiting the length of the model simulations. A comparison of the
model simulations to the observations of 1996 and 1997 indicate that with both tidal and
wind stress forcing the model, the model is able to reproduce the variability of the residual circulation but is unable to reproduce the observed velocity field .

various everyday work activities and organizational structures whereby a particular
form of professional female employee identity is constructed and the dominant
company discourse of professionalism is gendered. During 14 weeks of intensive
fieldwork, physical appearance, spatial dynamics, and work relationships between
female employees emerged as three interconnected processes through which the
women in the company identify and present themselves as professional female
workers. My analysis suggests that these processes are embedded in bodily dynamics
and intersects with the prevailing discourse of professionalism in the creation of
gendered and (hetero)sexualized identities of women in the company. In addition, I
discuss the notions of agency and resistance during this creation process and raise
critical questions for further consideration.

abstract:
It is the purpose of this study to analyze the unique nature of the sea
urchin fishery in Newfoundland and Labrador. Through the theoretical lens of
vernacular knowledge, the sea urchin fishery will be explored within the context
of the province's larger fishing industry, following the collapse of ground fisheries
of the early 1990s. The occupational folklife of a group of sea urchin fishers is
explored, specifically the role their vernacular knowledge plays in their industry.
Within the realm of this knowledge come the harvesters' work techniques,
narratives and attitudes. This knowledge makes for an occupational folk group
with a distinct sense of identity, autonomy and empowerment. The individuals
highlighted in the case study here are shown as having tremendous potential for
a co-management function within this fledgling fishery in Newfoundland and
Labrador.
