description: Quantum Internetworking is a recent field that promises numerous interesting applications, many of which require the distribution of entanglement between arbitrary pairs of users. This work deals with the problem of scheduling in an arbitrary entanglement swapping quantum network - often called first generation quantum network - in its general topology, multicommodity, loss-aware formulation. We introduce a linear algebraic framework that exploits quantum memory through the creation of intermediate entangled links. The framework is then employed to apply Lyapunov Drift Minimization (a standard technique in classical network science) to mathematically derive a natural class of scheduling policies for quantum networks minimizing the square norm of the user demand backlog. Moreover, an additional class of Max-Weight inspired policies is proposed and benchmarked, reducing significantly the computation cost at the price of a slight performance degradation. The policies are compared in terms of information availability, localization and overall network performance through an ad-hoc simulator that admits user-provided network topologies and scheduling policies in order to showcase the potential application of the provided tools to quantum network design.

description: Canadian nurses volunteered for military service in overwhelming numbers during the Second World War (1939--1945), comprising a second generation of military nurses known by rank and title as Nursing Sisters. Prevailing discourses portray them as 'extraordinary women,' patriots, heroines, feminists, and technological change agents. A small, diffuse body of literature documents their enlistments and postings but we know relatively little regarding how multiple identities and variables intersected to shape their experiences. This research examines Canadian military nurses' work from a feminist perspective through the lens of medical technology and discourse analysis, analyzing how variables such as gender, class, race, ethnicity, nation, marital status, and age intersected to shape their experiences during the Second World War. Based on oral histories, military records, professional literature, and archival sources, I ask: Who enlisted as Nursing Sisters? How did the military transform them into military nurses? What influenced decisions concerning where and how they served? In what technological and military contexts did they practice? How did these contexts shape the nursing care of soldiers? What influenced the transfer of technology to nurses? How did these experiences shape wartime and postwar civilian nursing practice? How did shared experiences as military nurses and as soldiers influence postwar identity as Nursing Sisters? War enabled the transformation of at least 4381 civilian nurses into Canadian Nursing Sisters who served 'for the duration.' They were posted to England, Northwest Europe, the Mediterranean, Hong Kong, and military hospitals across Canada, in Newfoundland, the United States, and South Africa. They worked in military general and specialty hospitals, hospital ships and trains, prisoner of war and internment camps, casualty clearing stations, field dressing stations, and field surgical units. Medical technology legitimated their presence within a complex military-medical-technological system while gender shaped their presence there as professional nurses, professional soldiers, and quintessential women. I argue that medical technology, gender, and war situated the Nursing Sisters as an expandable and expendable feminine workforce for the military, legitimated their presence at the frontlines of both war and medical technology, and facilitated the formation of a symbolic community and a social memory as military nurses.
Territorial identity: The "third category" of identity in Normative Pluralism

Subjects: subject: Political Science, General.

description: Normative Pluralism is a field of academic literature that attempts to reconcile the growing diversity within modern states by defining rules and norms to manage the relationships between differing identity groups. For the most part, normative pluralism has been focused on reconciling the relations between groups who exhibit one of two categories of identity: national identities and cultural identities. Much of the debate within the field of normative pluralism is in defining within which category an identity should be included and which rights and responsibilities should be assigned to it. However, there is another form of identity that while increasing in frequency and strength has been almost completely ignored by frameworks of normative pluralism---territorial identity. This presented thesis contends that territorial forms of identity comprise a "third category" of identity that frameworks of normative pluralism must address. More precisely, this thesis analyses the academic literature of normative pluralism and finds that, despite the strong connection between territory and identity, territorial identities are invisible in the academic debate within normative pluralism. This thesis explains the power and stability of territorial identities within the public sphere by outlining a theory of how territorial identities are formed, maintained, and transmitted through the relationship of three distinct phenomena: territoriality, narrative, and banal flagging. In a case study, the thesis reveals practical evidence of territorial identity, and the three phenomena that construct it, by analyzing the text of the editorials by three Albertan newspapers over the span of a single year.

description: Temporal, kinematic and kinetic patterns of independent walking (IW) in toddlers have been characterized in various studies with postural control identified as a critical component influencing the coordination between gait mechanisms to maintain a dynamic equilibrium. Variations in parameters across development indicate that toddlers possess more adult-like integration capabilities in locomotor control after 4 to 5 months of independent walking (Bril & Breniere, 1989, 1990, 1991, 1992). However, whether this integration would be influenced in a subtle complex locomotor task, obstacle crossing remains unknown. This study examined locomotor modulation during obstacle crossing in eight healthy toddlers (six males and two females; mean height = 80.6 cm) with 1 to 8 months IW experience. At least five trials of unobstructed walking (UW) and obstacle crossing (OC) were recorded using a Vicon motion analysis system (Oxford Metric Ltd, Oxford, UK). Lower extremity trajectories during unobstructed walking and while crossing a visible fixed obstacle were analyzed (Visual3D Motion Analysis System, C-motion Inc., Rockville, Maryland. US). As months of walking increased, segmental trajectories over the obstacle appeared to be more consistent. With 4- to 5-month IW toddlers displaying more adult-like OC patterns. This tendency was reflected by less variability of leading and trailing toe-to-obstacle distance (TD) and crossing stride length (SL). As IW experience increased, safety and stability were improved as the leading and trailing toe clearance distance over the obstacle (TC), knee flexion, crossing step length (SL), and heel distance (HD) increased accordingly. The most dramatic changes of these variables occurred after 4 to 5 months IW. In addition, success rate increased as months of walking suggested that better integrated postural control was achieved.

Publisher: name: Zenodo
Year: 2020
Subjects: Energy systems (production, distribution, application)
grid flexiblity, grid automation, grid control, distribution grid protections, islanding operation, energy forecasting, fault detection and location.

description: The expected increasing share of variable RES is challenging the electric grid in terms of reliability, stability and
 security of supply. Indeed, the European renewable target for 2030 (32% of total energy consumed) means that more
 than 50% of electricity will be generated from RES, most of which will be connected to the MV and LV grids. As
 an answer to these present and incoming challenges, FLEXIGRID project proposes to improve the distribution grid
 operation making it more flexible, reliable and cost-efficient, through the development of 4 HW and 4 SW solutions.
 Furthermore, a single open source platform will integrate the different solutions making them interoperable with the
 IT systems used by the energy stakeholders, increasing its replication potential.
 With the aim of increasing the project’s replication potential, 8 use cases have been identified to address EU most
 common distribution grid problems. These use cases are represented by 4 complementary demo-sites ready to upgrade
 FLEXIGRID solutions towards TRL8: a rural and peri-urban network in Spain with a RES share of 39%; a resort in
 the Greek Island of Thasos able to integrate 10% of RES; an urban grid in the city of Zagreb with congested areas, and
 an isolated valley in the South-Tyrol region of Italy with more than 50% of hydroelectric energy.
 To reach the project objectives, the consortium counts with partners representing all the energy system value-chain. In
 this sense, 2 RTOs and 2 Universities will work together with 5 technology providers to develop the project solutions
 and deploy them in the four demo-sites, represented by 3 DSOs and 2 large companies. Finally, 2 associations will
 ensure the exploitation and dissemination of the project results along the EU energy community.
 Finally, FLEXIGRID will support the ‘Clean Energy for All’ Europeans package while actively cooperating with
 BRIDGE initiative thanks to the presence of the consortium in 10 of its projects

Towards more culturally inclusive communication design practices: exploring creative participation between non-Indigenous and Indigenous people in Australia
Creators: name: St John, Nicola
Publisher: name: Swinburne
Year: 2024

description: Currently, Aboriginal and Torres Strait Islander narratives and participation within communication design practices in Australia are scarce. The Australian communication design industry, currently reinforcing Eurocentric practices, needs to develop a better understanding of the social and cultural dimensions of design and to provide more inclusive practices for designers from underrepresented or marginalised groups. Through case study analysis, this paper explores and discusses a more inclusive way of working with Indigenous people and content within communication design. It draws from and applies principals of Transformative Participatory Action research to communication design practice a more inclusive model for Indigenous creative practice within Australia. This approach moves away from co-design and participatory design models to focus more on participatory action, active engagement and empowering Indigenous communities through design.

description: Multi-messenger searches for BNS and NSBH mergers are currently one of the most exciting areas of astronomy. The search for joint electromagnetic and neutrino counterparts to GWs has resumed with O4. To support this effort, public semi-automated data products are sent in near real-time and include localization and source properties to guide complementary observations. In preparation for O4, we have conducted a study using a simulated population of compact binaries and a MDC in the form of a real-time replay to optimize and profile the software infrastructure and scientific deliverables. End-to-end performance was tested, including data ingestion, running online search pipelines, performing annotations, and issuing alerts to the astrophysics community. We present an overview of the low-latency infrastructure and the performance of the data products that are now being released during O4 based on the MDC. We report the expected median latency for the preliminary alert of full bandwidth searches (29.5s) and show consistency and accuracy of released data products using the MDC. For the first time, we report the expected median latency for triggers from early warning searches (-3.1s), which are new in O4 and target neutron star mergers during inspiral phase. This paper provides a performance overview for LVK low-latency alert infrastructure and data products using the MDC and serves as a useful reference for the interpretation of O4 detections.
Iterative methods for incompressible flow

Subjects: subject: Mathematics.

description: The goal of this thesis is to illustrate the effectiveness of iterative methods on the discretized Navier Stokes equations. The standard lid-driven cavity in both 2-D and 3-D test cases are examined and compared with published results of the same type. The numerical results are obtained by reducing the partial differential equations (PDEs) to a system of algebraic equations with a stabilized P1-P1 Finite Element Method (FEM) in space. Gear's Backward Difference Formula (BDF2) and an adaptive time stepping scheme utilizing a first order Backward Euler (BE) startup and BDF2 are then utilized to discretizc the time derivative of the Javier-Stokes equations. The iterative method used is the Generalized Minimal Residual (GMRES) along with the selected preconditioners Incomplete LU Factorization (ILU), Jacobi preconditioner and the Block Jacobi preconditioner.
Analysis of malaria and HIVAIDS data from the 2006 Uganda Demographic Health Survey

description: Despite the fact that extensive research has been done on malaria and HIV/AIDS, they are still major public health problems in Uganda with annual estimates of 10 million cases and 43,000 deaths for malaria and an HIV prevalence of 5.4% that has not changed since 2008. In this thesis, malaria prevalence and the associated risk factors in children below the age of five was investigated. Data from the Uganda Demographic Health Survey were analyzed on 7,336 children. Logistic regression was used to examine the risk factors of malaria. Malaria prevalence decreased with use of bed nets, an increase in the child's wealth status, an increase in the mother's education level and also with an increase in the child's age. Interactions between age and wealth index, and residence and wealth index were significantly associated with malaria prevalence. Prevalence was also higher among rural residents. It is suggested that malaria control measures be targeted to less advantaged groups of people. Knowledge of prevention and transmission of HIV/AIDS among 2,386 adult men and 8,531 adult women in Uganda was also examined in the thesis using the Uganda Demographic Health Survey. Logistic regression was used to examine determinants of knowledge of prevention and transmission of HIV/AIDS. Knowledge was generally higher among the men. Knowledge also increased with increases in wealth status and educational attainment. It is suggested that health education especially among women must underlie intervention programs to influence prevention and transmission of HIV/AIDS in Uganda.
Montaigne et Rousseau Scepticisme existentiel et parcours métaphysique

description: Notre thèse tente de porter un éclairage sur la nature du scepticisme existentiel à partir de l'analyse et de la comparaison des métaphysiques montaignienne et rousseauiste. Dans notre premier chapitre, nous examinons d'abord l'essai "Apologie de Raymond Sebond" pour mieux comprendre, à partir des figures de la métaphysique qui s'y dessinent---criticisme, ontothéologie et scepticisme---, la portée du scepticisme réflexif de Montaigne (partie I). Ensuite, nous portons notre regard sur l'essai "De l'expérience" afin de voir, en prenant appui sur les figures de la métaphysique qui s'y voient---expérience, égologie et philosophie de l'existence---, de quelle façon cette métaphysique sceptique s'actualise en une forme de scepticisme existentiel (partie II). Dans notre deuxième chapitre, nous procédons d'abord a l'étude de la "Profession de foi du Vicaire savoyard" de manière à saisir, en articulant les figures de la métaphysique qui apparaissent dans cet écrit---mythologie, ontothéologie et scepticisme---, le scepticisme involontaire de Rousseau (partie I). Ensuite, nous faisons l'analyse des écrits autobiographiques, en particulier des Rêveries du Promeneur solitaire, où l'accent mis sur des figures particulières de la métaphysique---expérience, égologie et philosophie de l'existence---vient montrer comment se concrétise cette métaphysique sceptique en une forme de scepticisme existentiel (partie II). Dans notre troisième chapitre, nous comparons les pensées de Montaigne et de Rousseau sur chacune des figures de la métaphysique relevées dans notre analyse de leur double parcours. Par le biais de cette comparaison nous suggérons que le scepticisme existentiel peut prendre une forme plus inquisitrice ou une forme plus sentimentale selon qu'il est principalement animé par le jugement réflexif (Montaigne) où l'assentiment du coeur (Rousseau).
HIV-1 Tat protein down regulates interleukin-7 receptor alpha on CD8 T cells

description: Expression of the IL-7 receptor alpha-chain (CD127) is decreased on CD8 T-cells in HIV infected patients and recovers in those receiving antiretroviral therapy with sustained viral suppression. Here I demonstrate that the HIV Tat protein, acting in a paracrine fashion, specifically down regulates cell surface expression of CD127 on human CD8 T-cells. The effect of Tat on CD127 is dose- and time-dependent, specific, and can be blocked with anti-Tat monoclonal antibodies or by pre-incubating Tat with heparin. Pre-incubation of purified CD8 T-cells with Tat protein inhibited CD8 T-cell proliferation and perforin synthesis following stimulation with IL-7. I also show that low CD127 expression on CD8 T-cells from HIV+ patients recovers to normal levels when CD8 T-cells are isolated and cultured in vitro. Recovery ofCD127 was completely inhibited by the addition of HIV Tat protein to the culture media. This suggests that soluble factor(s) are responsible for low CD127 expression on circulating CD8 T-cells in HIV+ individuals and further supports the role of Tat in this process. I have elucidated the mechanism by which Tat removes CD127 from the cell surface. Soluble Tat protein is initially taken up by CD8 T-cells via endocytosis and exits the endosome through a process dependent on endosomal acidification. Once in the cytoplasm, Tat localizes to the inner leaflet of the cell membrane where it binds to the cytoplasmic tail of CD127 and induces receptor clustering and internalization. Through its association with Tat, CD127 is then directed to the proteasome for degradation. While Tat and IL-7 both independently down regulate surface expression of CD127, I have demonstrated that at near physiologic concentrations these viral and host factors act synergistically to suppress CD127. Inhibition of JAK kinase completely blocks IL-7's ability to down regulate CD127 on the surface of CD8 T-cells and also abolishes synergy with Tat. Interestingly, while Tat acts synergistically with IL-7 to reduce CD127 expression, it antagonizes IL-7 induced cell proliferation and Ki-67 expression. Since IL-7 signalling is essential for optimal CD8 T-cell proliferation and function, the down regulation of CD127 and apparent inhibition of cytotoxic activity by Tat may play an important role in HIV induced immune dysregulation and impaired cell mediated immunity.
Why Do Borrowers Choose Arms Over FRMS? : A Behavioral Investigation in the U.S. and Japan

description: Why Do Borrowers Choose Arms Over FRMS? :

A Behavioral Investigation in the U.S. and Japan

by Masaki Mori

In the U.S., a considerable number of borrowers still choose adjustable rate mortgages (ARMs) over fixed rate mortgages (FRMs), even with historically low interest rates. During 2004-2005, when interest rates remained at 30-year lows, ARMs accounted for approximately one-third of all mortgage originations.

Kahneman and Tversky's Prospect Theory?s reflection hypothesis suggested that people tend to be more risk-averse in positive decision situations, while they tend to be more risk-seeking when making negative choices. The first purpose of this study is to examine descriptive reasons for the popularity of ARMs in the U.S. People of different cultures often evaluate uncertain events in different ways. Hofstede developed a cultural dimension, uncertainty avoidance (UA), where UA is defined as the extent to which people feel threatened by uncertain situations. The second purpose of this study is to test the role of UA on the choice of mortgage products using data from two cultures (U.S. and Japan), potentially differing in attitude toward uncertain situations. Controlled experiments were conducted using 92 U.S. participants and 49 Japanese participants.

Results of analysis supported Prospect Theory?s reflection hypothesis, suggesting that risk-averse people tend to become more risk-seeking when choosing a mortgage type, leaning more toward ARMs when people frame the mortgage choice problem as part of a loss situation. The results of the intercultural comparison portion of the study supported the research hypothesis that UA works as a moderating variable for Prospect Theory?s reflection hypothesis, suggesting that risk-averse people with lower UA scores more dramatically change from a risk-averse preference for a fixed-rate bond to a more risk-seeking preference for an adjustable-rate mortgage, than risk-averse people with higher UA scores do. Overall, results of this study suggested that borrowers behave differently depending on their propensity for current consumption, the level of UA, and how they frame the mortgage choice decision.

This study contributes to existing mortgage choice literature by incorporating psychological and cultural traits to examine borrowers? attitudes towards interest rate risk with regard to residential mortgages. The findings are of great importance globally for governments and lenders in creating and introducing new mortgage products in countries with diverse cultures.
Molecular characterization of alpha(1)-adrenoceptor gene family and its role in salt-induced high blood pressure in rainbow trout (Oncorhynchus mykiss)

description: alpha1-Adrenoceptors (alpha1-ARs) are members of the G-protein coupled receptor superfamily of membrane proteins that mediate the actions of the endogenous catecholamines, adrenaline and noradrenaline. alpha 1-ARs are the prime mediators of vascular smooth muscle contraction and hypertrophic growth, and play a key role in the regulation of arterial blood pressure. Four weeks of high-salt diet (11% NaCl) significantly increased blood pressure (37.1%). An average two-fold decrease in alpha1D-AR mRNA expression was observed in the DA, ABA and EBA in high-salt diet fed trout. The chronically hypertensive fish exhibited a blunted vascular response to hypercapnia and exogenous catecholamines. These results suggest either a lowered vascular response capacity or that alpha1D-AR down-regulation occurred in high-salt diet fed fish as a consequence of the elevated blood pressure. The alpha1D-AR is, at least in part, involved in salt-induced high blood pressure in rainbow trout. This study is the first to characterize the alpha1-AR gene family at molecular level in any fish species, and provides the first evidence for a link between alpha1-ARs and salt-induced high blood pressure.

description: In this work we present 21cmFirstCLASS, a modified version of 21cmFAST, the most popular code in the literature for computing the anisotropies of the 21-cm signal. Our code uses the public cosmic microwave background (CMB) Boltzmann code CLASS, to establish consistent initial conditions at recombination for any set of cosmological parameters and evolves them throughout the dark ages, cosmic dawn, the epoch of heating and reionization. We account for inhomogeneity in the temperature and ionization fields throughout the evolution, crucial for a robust calculation of both the global 21-cm signal and its fluctuations. We demonstrate how future measurements of the CMB and the 21-cm signal can be combined and analyzed with 21cmFirstCLASS to obtain constraints on both cosmological and astrophysical parameters and examine degeneracies between them. As an example application, we show how 21cmFirstCLASS can be used to study cosmological models that exhibit non-linearities already at the dark ages, such as scattering dark matter (SDM). For the first time, we present self-consistent calculations of the 21-cm power spectrum in the presence of SDM during the non-linear epoch of cosmic dawn. The code is publicly available at https://github.com/jordanflitter/21cmFirstCLASS.

description: In their recent work ``Well-posedness, regularity and asymptotic analyses for a fractional phase field system'' (Asymptot. Anal. 114 (2019), 93--128), two of the present authors have studied phase field systems of Caginalp type, which model nonconserved, nonisothermal phase transitions and in which the occurring diffusional operators are given by fractional versions in the spectral sense of unbounded, monotone, selfadjoint, linear operators having compact resolvents. In this paper, we complement this analysis by investigating distributed optimal control problems for such systems. It is shown that the associated control-to-state operator is Fréchet differentiable between suitable Banach spaces, and meaningful first-order necessary optimality conditions are derived in terms of a variational inequality and the associated adjoint state variables.
The genetic mapping and characterization of the m196 craniofacial and fin mutation in zebrafish

description: The m196 mutation, a result of an ENU mutagenesis screen in zebrafish, disrupts embryonic development resulting in a delay of proper gill arch cartilage differentiation and a disruption of median and pectoral fin fold development. Mutant phenotypes arise at 24 hours post fertilization (hpf) with the onset of fin fold development and lead to early mortality between 30 hpf and 2 weeks from unknown causes. m196 delay and disruption of craniofacial chondrogenesis is possibly due to the initial displacement of the pharyngeal pouches and dismorphogenesis of the branchial arches. Cells expressing genetic markers of the fin fold and neural crest accumulate in a disorganized manner along the tail. Using meiotic mapping techniques, we have mapped the m196 mutation to a SSLP marker zCtg37A on LG17. We are analyzing candidate genes in search of the m196 mutation. These results will lead to the identification of a genetic factor essential for craniofacial and fin development in zebrafish.

description: Simultaneous machine translation (SiMT) outputs translation while reading the source sentence. Unlike conventional sequence-to-sequence (seq2seq) training, existing SiMT methods adopt the prefix-to-prefix (prefix2prefix) training, where the model predicts target tokens based on partial source tokens. However, the prefix2prefix training diminishes the ability of the model to capture global information and introduces forced predictions due to the absence of essential source information. Consequently, it is crucial to bridge the gap between the prefix2prefix training and seq2seq training to enhance the translation capability of the SiMT model. In this paper, we propose a novel method that glances future in curriculum learning to achieve the transition from the seq2seq training to prefix2prefix training. Specifically, we gradually reduce the available source information from the whole sentence to the prefix corresponding to that latency. Our method is applicable to a wide range of SiMT methods and experiments demonstrate that our method outperforms strong baselines.

Trump's ragged army

description: In less than two weeks the American presidential election campaign will be over and sociopolitical commentary will shift a gear. Until recently, the chatter was predominantly about why Donald Trump was doing so much better than expected, and the reasoning tended to involve elites, globalisation, unemployment, political correctness and angry white males. There's still a tiny chance that Trump will win on 8 November, and if that happens those lines of enquiry will hit overdrive. But the overwhelming likelihood is that the Republican will be trounced by Hillary Clinton, and the chronicles will very quickly shift to something more specific: how on earth did the nomination process of America's centre-right party produce such a doozy? What does it say about the Republican Party and, perhaps, conservative politics more generally?
A Metis Metier: Transportation in Rupert's Land

Year: 2005
Subjects: subject: History, Canadian.

description: This thesis argues that the provision of transportation services represented one of the core economic activities in the area of western Canada known as Rupert's Land, and that during the period from the amalgamation of the Hudson's Bay Company (HBC) and the North West Company (NWC) in 1821 until the arrival of the railroads in the area in the mid-1880s, the Metis played a central role in providing those services. The thesis reviews the nature of transportation arrangements within the fur industry of Rupert's Land and describes Metis participation in those arrangements. Metis involvement in both York Boat work and overland transportation by Red River Cart are discussed in detail, as are the York Boats and Red River Carts themselves. The overall value to the Metis economy of their participation in the provision of transportation services is also estimated.

description: The present study aimed to document three athletes' in depth-stories to examine their application of resonance and how it influenced their experience of their sport and life. Each athlete took part in a resonance-based intervention involving seven interviews held approximately every second week, three non-intrusive interviews conducted at the site of competitions, daily reflective journaling, reading a book on resonance (Newburg, 2004), and a post-intervention interview four weeks after the end of the intervention. Two means of analysis were used; deductive categorization and narrative analysis. Two individuals developed and applied their personal process of resonance. As a result, they felt the way they wanted to feel in their endeavors, and enjoyed an increased sense of control and acceptance of themselves and their environment. The three athletes' stories shed light on the importance of reflection and ownership in the process of resonance. This study also sheds light on the role of the facilitator in the intervention.

description: In neuronal and placental cells, proliferation-associated leucine-rich protein 31 is an anti-apoptotic, cell cycle-related protein in its intact form, and upon cleavage by caspase-3, is pro-apoptotic. However, whether PAL31 is expressed in the follicle and is modulated during follicular development and atresia is not known. The expression and regulation of ovarian PAL31 were investigated using immature rat models and a granulosa cell culture system. PAL31 was ubiquitously expressed in all follicular cell types. eCG caused a significant decrease in granulosa cell PAL31 protein content during granulosa cell differentiation and late stage follicle growth. Gonadotropin withdrawal prevented an increase in ovarian weight after eCG treatment, but failed to induce granulosa cell apoptosis and PAL31 cleavage. Finally, estradiol stimulated PAL31 expression in the granulosa cells of preantral and early antral follicles. These results demonstrate for the first time that PAL31 is regulated by key reproductive hormones during follicular development in vivo.
Effect of surfactants on the hydrodynamics of bubble columns and three-phase fluidized beds

description: Most hydrodynamic correlations and models used for gas-liquid-solid fluidized beds implicitly assume that the major physical properties of the liquid (density, viscosity and surface tension) are sufficient to characterize bubble dynamics. While this is true for pure liquids, multi-component liquids require additional properties due to surface-active agents preferentially accumulating at the gas-liquid interface. Experiments were first conducted to evaluate the effects of surface-active agents (alcohols as well as commercial anionic, cationic and non-ionic surfactants) on the phase holdups and minimum liquid fluidization velocities in a fluidize bed composed of air, water and glass beads of 1.2 and 5 mm in diameter. The gas-liquid interfacial behaviour of the liquid solutions was then characterized by measuring the foamability as well the dynamic surface tension and dilatational surface elasticity using the maximum pressure bubble method. The presence of surface-active agents decreases the minimum liquid fluidization velocity and the effect is more important for the larger particles. The effect of surfactants on the bed phase holdups, and in particular the gas holdup, is significant and more pronounced in the coalesced bubble flow regime where foaming occurred. Further, the bed gas holdups are lower than those observed in the freeboard. The widely used gas holdup correlations proposed by Han et al. (1990) and Larachi et al. (2001) failed. Furthermore, the approach of Gorowara and Fan (1990) which uses the dynamic surface tension also failed as all surfactant solutions present similar phase holdups despite very different surface tension behaviour. More fundamental work is required to elucidate the complex relationship between the physical properties of a multi-component liquid, the degree of bubble coalescence and the hydrodynamic features of multiphase reactors.

Semi-empirical and ab initio study of the ideal strengths and elastic properties of covalent crystals and FCC metals
Creators: name: Kamran, Sami
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2008
Subjects: subject: Physics, General.

description: The present thesis consists of a number of studies on the elastic properties of covalently bonded crystals, the ideal strengths of a selection of face-centred cubic (FCC) metals and the anomalously large shear modulus of iridium. Semi-empirical formulae for both bulk modulus B and shear modulus G of covalent crystals were elaborated in terms of bond length and ionicity fraction of the bonding. The resulting equations can be applied to a broad selection of covalent materials and their predictions are in good agreement with the experimental data and the results from first-principles calculations. Furthermore, the correlation between the ratio G/B and the aforementioned bonding parameters was investigated. The analysis of this relationship demonstrates that the bond length is the predominant parameter responsible for the brittle features of covalent materials. The ideal shear and tensile strengths of FCC transition metals were examined through density functional theory (DFT)-based computations. These results allowed establishing a new indicator of ductility, namely the ratio of ideal shear strength to ideal tensile strength taum/sigma <111>. Moreover, it was found that palladium can sustain a surprisingly long range of deformation. Based on the analysis of density of states (DOS) curves, it is suggested that creation of angular features is responsible for the notable amount of distortion suffered by palladium. The electronic origin of the anomalously large elastic modulus and intrinsic brittleness of FCC iridium were studied using ab initio DFT-based calculations. The electron localisation function (ELF) and bond orders (BO) of iridium and a selection of FCC metals were calculated and then used to evaluate the directionality and the strength of the bonds. The analysis of the trend of bond strength versus elastic moduli, Cauchy pressure and the ratio of shear modulus over bulk modulus suggests that the bond strength is the primary factor that causes the abnormally high modulus of iridium and its intrinsic brittleness.
Les enjeux de la représentation de la transgression chez Gabrielle Wittkop

description: Gabrielle Wittkop (1920-2002) est l'auteur d'une oeuvre qui n'est ni belle, ni bonne, mais radicalement transgressive et demeurée marginale dans la mesure ou les idéologies et valeurs qui y sont véhiculées refusent de se plier aux exigences de la masse. Son discours, inspire à plusieurs égards par la parole de Sade, ose représenter ouvertement les plus violents des fantasmes à l'abri des clichés et stéréotypes qui entourent habituellement leur représentation. Afin de saisir la portée transgressive des fictions de cet auteur, il est impératif d'exposer les différents mécanismes de remise en question de la doxa qui sous-tendent, selon nous, son oeuvre. À travers l'analyse de trois textes représentatifs, Le sommeil de la raison (2003), La marchande d'enfants (2001) et Le nécrophile (1972), cette thèse vise à dégager, au niveau de la représentation, les enjeux principaux du discours littéraire de Wittkop. Elle mettra en valeur, par le biais d'une étude de la thématique, de l'esthétique et des formes discursives, le rôle de la transgression littéraire comme subversion de la norme. D'un point de vue critique, elle montrera que le discours social se dégageant des fictions de cet auteur révèle l'ensemble des valeurs et idéologèmes inhérents à la société bourgeoise comme signes d'un refoulement pathologique de nos désirs.

description: This paper concerns studies on smooth transonic flows with nonzero vorticity in De Laval nozzles for a quasi two dimensional steady Euler flow model which is a generalization of the classical quasi one dimensional model. First, the existence and uniqueness of smooth transonic flows to the quasi one-dimensional model, which start from a subsonic state at the entrance and accelerate to reach a sonic state at the throat and then become supersonic are proved by a reduction of degeneracy of the velocity near the sonic point and the implicit function theorem. These flows can have positive or zero acceleration at their sonic points and the degeneracy types near the sonic point are classified precisely. We then establish the structural stability of the smooth one dimensional transonic flow with positive acceleration at the sonic point for the quasi two dimensional steady Euler flow model under small perturbations of suitable boundary conditions, which yields the existence and uniqueness of a class of smooth transonic flows with nonzero vorticity and positive acceleration to the quasi two dimensional model. The positive acceleration of the one dimensional transonic solutions plays an important role in searching for an appropriate multiplier for the linearized second order mixed type equations. A deformation-curl decomposition for the quasi two dimensional model is utilized to deal with the transonic flows with nonzero vorticity.

description: The work presented in this thesis focuses on exploring the versatile chemistry of 4-aryl substituted 1,2,4-triazole derivatives. The ligands 4-(4'-nitrophenyl)-1,2,4-triazole (npt) and 4-(4'-carboxyphenyl)-1,2,4-triazole (Hcpt) were prepared following a modified known synthetic strategy. Reaction of either of these ligands with transition metal or lanthanide precursor salts resulted in two novel complexes, namely [FeII3(npt) 6(EtOH)4(H2O)2](ptol)6·4(EtOH) (1) and [DyIII4(mu3-OH) 2(mu3-O)2(cpt)6(MeOH)6(H 2O)]2·15,(MeOH) (5), and of five analogous compounds. In the case of 1, the structural analyses and the magnetic properties indicated that the complex consisted of a linear trinuclear Spin Crossover FeII compound with a T1/2 of 148 K. For this complex, the SC-XRD analyses were performed at 100 and 181 K in order to characterize the structural changes occurring during the spin transition. For 5, the magnetic and structural data indicated that the complex was a dumbbell-shaped cubane dimer {DyIII 4}2 for which each cubane unit is a Single-Molecule Magnet with a small effective energy barrier.
