PERLE (Powerful Energy Recovery Linac for Experiments) est un accélérateur linéaire à recouvrement d'énergie (ERL) basé sur la technologie à cavité radiofréquence supraconductrice qui sera installé au Laboratoire de Physique des 2 Infinis Irène Joliot-Curie (IJCLab) en France. Avec une puissance de faisceau cible de 10 MW, PERLE vise à démontrer le fonctionnement multi-passe à haute intensité en onde continue pour valider des options pour les futures machines à haute énergie, telles que l'ERL de 50 GeV proposé pour LHeC (Large Hadron Electron Collider) et FCC-eh (Future Circular Electron-Hadron Collider), et à accueillir des expériences dédiées en physique des particules et en nucléaire. Dans les ERLs à haute intensité, l'instabilité de Beam Breakup (BBU), résultant de l'interaction entre le faisceau et les modes d'ordre supérieur (HOMs) des cavités, est une préoccupation majeure pour leur fonctionnement stable. Les HOMs induits par le faisceau peuvent augmenter la charge thermique de la cavité à température cryogénique et causer des instabilités du faisceau. Des coupleurs HOM sont installés dans les tubes de faisceau de la cavité pour absorber l'énergie des HOMs et atténuer ces effets. Cette thèse présente la conception et l'optimisation de plusieurs coupleurs HOM coaxiaux pour les cavités elliptiques en Nb avec 5 cellules à 801,58 MHz de la configuration PERLE ERL à 500 MeV. La transmission RF des coupleurs HOM a été optimisée pour améliorer l'amortissement des HOMs les plus dangereux. Les coupleurs HOM optimisés ont été intégrés dans des groupes d'extrémité pour simuler leur performance d'amortissement et leur comportement thermique. Les coupleurs HOM optimisés ont été imprimés en 3D en époxy et revêtus de cuivre. Des mesures RF à faible puissance ont été effectuées sur les coupleurs HOM produits installés dans des cavités en cuivre de type PERLE pour valider leur performance d'amortissement et proposer plusieurs groupes d'extrémité pour la cavité PERLE avec 5 cellules afin d'atténuer les HOMs en dessous des limites d'instabilité BBUThe Powerful Energy Recovery Linac for Experiments (PERLE) is an energy recovery linac (ERL) facility based on superconducting radio-frequency (SRF) technology to be hosted at the Laboratoire de Physique des 2 Infinis Irène Joliot-Curie (IJCLab) in France. With a target beam power of 10~MW, PERLE aims to demonstrate the high-current, continuous wave, multi-pass operation to validate options for future high-energy machines, such as the 50 GeV ERL proposed for the Large Hadron Electron Collider (LHeC) and the Future Circular Electron-Hadron Collider (FCC-eh), and host dedicated particle physics and nuclear experiments. In high-current ERLs, the regenerative Beam Breakup (BBU), emerging from the beam and cavity Higher Order Modes (HOMs) interaction, is a major concern for their stable operation. Beam-induced HOMs can increase the cavity heat load at cryogenic temperature and cause beam instabilities. HOM couplers are installed in the cavity beam pipes to absorb HOM energy and mitigate these effects. This thesis presents the design and optimization of several coaxial HOM couplers for the 5-cell 801.58 MHz elliptical Nb cavities of the 500 MeV PERLE ERL configuration. The RF transmission of the HOM couplers was optimized to enhance the damping of the most dangerous HOMs. The optimized HOM couplers were integrated into endgroups to simulate their damping performance and thermal behavior. The optimized HOM couplers were 3D-printed in epoxy and copper-coated. Low-power RF measurements were conducted on the produced HOM couplers installed in copper PERLE-type cavities to validate their damping performance and propose several endgroups for the PERLE 5-cell cavity to mitigate HOMs below the BBU instability limits

O presente estudo procura examinar a questão da desigualdade de gênero na divisão de tarefas domésticas e responsabilidades familiares entre membros de casais de aeronautas, profissionais da aviação comercial (comissários e pilotos). Procura-se investigar neste subgrupo como ocorre a conciliação entre a vida familiar e o trabalho de turnos alternantes. Utiliza-se como referencial básico a contribuição de cientistas sociais em seus estudos acerca das relações de gênero na contemporaneidade. Homens e mulheres trabalham cada vez mais em horário integral e se veem divididos diante de propostas igualitárias de relacionamento em contraposição a práticas mais tradicionais. Parece que a transformação das mentalidades nas relações de gênero foi insuficiente no que diz respeito a uma divisão mais igualitária das tarefas domésticas. A lacuna deixada pelas mulheres na vida privada, com sua entrada maciça no mercado de trabalho, não foi ocupada por outros, senão por elas próprias, que se dividiram e se multiplicaram em muitas para poder conciliar família e profissão. Após uma revisão de literatura, foram realizadas entrevistas com quatro casais de aeronautas do Rio de Janeiro. Os dados obtidos nas entrevistas entraram em consonância com o que a literatura já vem discutindo sobre casais de outras categorias profissionais. As mulheres casadas e com filhos despendem mais tempo com o trabalho doméstico e com as responsabilidades familiares do que seus maridos. Diante desta constatação, percebe-se que a especialização de papéis ainda está fortemente ancorada nas ideologias de gênero tradicionais que regem os comportamentos de homens e mulheres contemporâneos, produzindo com isto um cenário desfavorável para ascensão profissional das mulheres e para um maior envolvimento dos homens com a vida familiar.
The main subject of this study is the gender inequality in the division of household chores and child care between spouses who work as crew members in civil aviation (flight attendants and pilots). This study reports an investigation of the relationships of nonstandard work schedules and family balance. It is based on the several studies conducted by social scientists about gender relations in the contemporary society. Men and women are engaged in full time work and confronted with an egalitarian social discourse and traditional patterns of behavior. It seems that the shift regarding gender relations and more balanced divisions of household chores are still insufficient. Women joined the workforce dealing with multiple roles to balance household chores and career. After reviewing several academic books and articles, interviews with four middle class flight crew members’ couples from Rio de Janeiro were conducted. The results were similar to other studies with couples from other professional categories: married women with children still do much more routine household chores than their husbands. The gender segregation of tasks associated with the traditional gender ideologies contribute to reinforcing the specialized roles, an unfavorable scenario for career development for women and greater involvement of men with family life.

This thesis explores the ways in which transnational same-sex couples construe and experience transnational migration, intimacy, and home. The study was initially born out of the need to contribute to the young, but growing body of scholarly work in relation to queer migration studies. For long, the figure of ‘the migrant’ was founded on heterosexual terms only, thus impeding any possibility of exploring the lives of those with non-normative gender and sexual identities. During the last two decades or so, new scholarship has tried to alter this picture, arguing for a more inclusive assessment of global migration. This project aims to further the scholarly conversations in this regard, but it also wishes to go beyond the traditional economic and political spheres in which the migrant is usually placed in; hence, it promotes a study of migration that is also preoccupied with the intimate and emotional life of LGBT+/queer migrants. In this sense, this research is interested in how 12 transnational same-sex couples (that are also binational) understand and practice intimate life and home. Indeed, examining the life of these couples in migration offers a unique opportunity to delve into the intimate and domestic dimensions of transnational migration, and therefore, to show how the research participants actively negotiated and sustained family life and a sense of belonging in today’s rapidly changing and globalising world. The ‘transnational’ component will be key across this thesis, as it enables the possibility of understanding the couples’ different movements, attachments, networking and (emotional and material) practices that explicate and buttress their migratory journeys. The study was carried through the use of ethnographic techniques, namely, narrative interviewing, observation, and the construction of material culture narratives at the participants’ home(s). This methodological combination allowed for an in-depth and careful exploration of the individual and coupled biographies of the research participants. Particularly, this thesis illustrates how working with material culture brings richness and additional depth to empirical data, as well as it provides new opportunities for creativity and interaction with research participants. In the end, this research project chiefly aims to provide gay men, lesbians, and other non-heterosexuals in transnational relationships additional tools to reflect on their lives, sense of belonging, citizenship status, and the value that is politically and socially bestowed on to their relationships, families and overall personal commitments. Indeed, I wish to bring attention to the intimate side of migration; to the fact that migrants, like the ones in this research, have meaningful and on-going personal and interpersonal attachments and commitments. This is why I argue that studying this can be key to a deeper and better understanding of the phenomenon of migration in the 21st Century.

The purpose of this qualitative study was to describe the experience of parents who have had a homebirth in the past two years in Perth. Studies conducted to date have predominantly used quantitative research methods, investigating the safety of homebirth and comparing home to hospital birth without exploring a couples experiences. A phenomenological approach was used as it seeks to understand human experience in context. The research design consisted of a field study, in which ten parent couples were interviewed and three homebirth videos observed. Data analysis was conducted according to the procedure outlined by Colaizzi (cited in Knaack, 1984, p. 110) which is to describe, interpret and extrapolate common themes and meanings. Of the ten couples interviewed four couples spoke of their first child's homebirth and the remaining six couples had three or four children who had been born at home. Research participants were attended to during their homebirth by one of five registered midwives. The essence of these parents' experiences of homebirth was gained through identifying significant statements from transcripts and field notes then clustering these into themes. The four essential themes were Constructing the Environment, Assuming Control, Birthing, and Resolving Expectations. The research findings provide health professionals and consumers with an insight into homebirth which challenges them to alter their practices and assumptions regarding this birth environment.

Today’s military encompasses a wide variety of families who are affected by deployments in multiple and complex ways. Following deployments, families must reconnect in their relationships and reestablish their way of life. Appropriate and effective communication during this time is critical, yet many military couples struggle with this process. Moreover, student service members/veterans and their families are in a unique position. In addition to coping with changes in their marital relationship, student veterans may feel isolated or unsupported on college campuses, often experiencing anxiety, depression, posttraumatic stress, or suicidality. The current study seeks to bridge the gap between the military family literature and the student service member/veteran literature by examining how deployment experiences, mental health issues, and communication patterns influence post-deployment relationship adjustment among student veterans. Analyses tested whether communication style and/or current mental health concerns mediate associations between combat experiences and couples’ relationship adjustment, as well as between experiences in the aftermath of battle and relationship adjustment. Results suggest that although posttraumatic stress is significantly related to deployment experiences among student veterans, participants report no significant negative effects of deployment on relationship adjustment. Communication style, however, was significantly associated with relationship adjustment, and a lack of positive communication was found to correlate with PTSD diagnosis. Research and clinical implications are discussed.

Thesis advisor: Dorothy A. JonesAs the United States population ages, knowing and understanding the older adult couple’s experience living with chronic illness at home is significant to inform new strategies of care, and planning of resources for the improvement in the health and well-being for a potentially vulnerable population. The purpose of this qualitative study was to better understand the older adult couple’s experience while living with chronic illness at home by answering the following research questions: What is the life pattern manifested by an older adult couple living with chronic illness at home? Are there common themes across the life patterns of older adult couples living with chronic illness living at home? The theoretical framework guiding this study was Margaret Newman’s Health as Expanding Consciousness using a hermeneutic-dialectic phenomenology method. The study’s sample consisted of 14 married older adults (> 65 years of age) couples living together at home. The research method explored the experiences of the older adult couple through dialogue within the context of their social environment in all its complexity. This approach gave voice to the older adult couples’ experiences and their meaning from their perspective, which facilitated insights about each older adult couple as well as common themes across the older adult couples. Three themes emerged from the study, (1) an unfolding pattern of living meaningfully as an older adult couple with chronic illness while moving through life transitions, (2) couple interconnectedness strengthens the bonding within the older adult couple and promotes self-growth, and (3) a resonating process within the older adult couple promotes movement toward expanding consciousness. Conceptual models are proposed. The findings suggest older adult couples living with chronic illness at home strive to live meaningfully while experiencing multiple life transitions embedded in a resonating process that facilitates change

Somatostatin (SST) is a peptide hormone that was originally identified in the hypothalamus and subsequently found throughout the central nervous system and in various peripheral organs. Generally classified as an inhibitory factor, SST is secreted by endocrine, neuronal and immune cells and acts to regulate cell secretion, neurotransmission and cell proliferation. There are five receptor-subtypes known to engage SST, termed SSTR1-5, all belonging to the superfamily of G-protein coupled receptors (GPCRs). Within the past few years, there has been a prepondef8:llce of evidence to suggest the importance of GPCR dimerization in receptor-biogenesis, regulation and pharmacology. It has been previously reported in our laboratory, that human (h) SSTR5 homo- and heterodimerizes with hSSTR1 in an agonist-regulated manner. However, it was unclear as to the contribution of each subtype in the formation of the hSSTR1/hSSTR5 heterodimer, the possible molecular determinants involved and the effects of heterodimerization on the pharmacology of the receptors. Furthermore, the dimerization properties of other hSSTRs including their heterodimerization remain undetermined. Here, we demonstrate that agonist binding to hSSTR5 and not hSSTR1 modulates the formation of the heterodimer, with particular emphasis on its carboxyl-terminal tail in specifying the interaction. We also determined the mechanics of the hSSTR2 homodimer, unlike the previous hSSTRs investigated, forms constitutive dimers that dissociate into monomers following activation with agonist. This feature is important for receptor trafficking, as preventing their dissociation impairs agonist-mediated endocytosis. Lastly, we investigated the heterodimerization of hSSTR2 and hSSTR5, an interaction that, like the hSSTR1/hSSTR5 heterodimer, is subtype-specific, requiring selective-activation of hSSTR2 and not hSSTR5. The heterodimer exhibited enhanced signalling characteristics including, prolonged activation of MAP kinases and an increase in the induction of the cyclin-dependent kinase inhibitor p27Kip1. These enhanced properties of the heterodimer conferred an extended growth inhibitory response. Dimerization of GPCRs, with particular emphasis on heterodimers, generates novel receptors with unique properties distinct from those of the individual receptor monomers/homodimers. An understanding on the mechanisms involved in GPCR dimerization could provide a rationale in future drug design.

This study examined The Margin Protection Program for Dairy’s impact on the “effective margins” or margins realized by dairy producers in various regions. Each selected margin and percentage of production history offered by the national policy was analyzed in a forecasting, national and regional manner. Couplet margins were simulated for fifteen regions from 2017 through 2020. Five scenarios were analyzed for the change in MPP’s effects under a 15%, 10%, and 5% drop in the price of milk as well as a 50% increase in the price of corn and a scenario where milk decreases 15% while corn prices simultaneously increases 25%. The results demonstrate that more than half of the regions have higher probabilities of triggering indemnities at every coverage level when compared to the US, MPP margin. Margins change in response to the policy effects, where lower coverage levels experience margin increase, and higher coverage levels experience margin decrease. In the US, MPP margin, risk reduction is observed at every coverage level. The program was found to decrease risk at most coverage levels, where higher shocks to the margin increased the protection offered by the program’s effects.

Many older couples face the dilemma of one of them developing an illness that results in their ability to cope with everyday living activities. The well spouse may struggle for many years with an increasing workload, both physical and mental. Ultimately, there may come a time, when nursing home placement becomes necessary. The aim of this research was to find out what the experience was like for the wife, with a husband who is ill and faces placement in a nursing home, and to determine whether nurses could do more to help them to cope with this difficult situation. Following ethics approval, nine wives were interviewed over a period of two years. Each of the experience was unique, but there were some common problems that many of the wives mentioned. Loneliness was considered by most of the wives as being extremely upsetting, even when they were living with other people, for example their children. The absence of their partner and long term confident was noticed particularly in the evening when, in the past, they had sat down together and watched television. Other reactions included guilt, grief, depression and a change in the husband/wife relationship. Many of the wives seemed to accept the situation, realising that they could no longer cope with their husband at home, they were also healthier than they had been when their husband was at home. This research has highlighted some important points when a wife finds herself in the situation of having to place her husband in a nursing home, although nurses are unable to assist with many of the effects on the wife of the placement, it is helpful to know that the friendliness of the staff, the care of the patient and the cleanliness and homeliness of the nursing home are helpful at this timeMaster of Nursing (Hons)

Le caractère fortement hydrophile des isolants thermiques bio-sourcés, a montré que les modèles classiques de transfert thermique ne sont pas suffisamment adaptés pour leur caractérisation thermique. Ce travail de thèse vise à répondre à cette problématique par des approches expérimentale et théorique des transferts couplés chaleur-humidité. Dans l’approche expérimentale, un isolant thermique en feutre de fibres de lin (FFL) a été développé puis caractérisé, dans différents états hygrométriques, au moyen d’un dispositif Plan Chaud asymétrique. Des isothermes d’adsorption de l’humidité corrélés aux modèles théoriques GAB, GDW et Park permettent une caractérisation hydrique de cet isolant. Dans l’approche théorique, un modèle physique, de transfert couplé chaleur-humidité au sein de l’isolant FFL humide, est proposé. Il est résolu numériquement, en configuration 3D transitoire, par la méthode de éléments finis sous COMSOL Multiphysics et par la méthode des différences finies, en configuration 1D transitoire, sous MATLAB. La méthode de Levenberg-Marquardt couplée avec le modèle direct 1D transitoire et les températures mesurées a permis d’estimer la conductivité thermique apparente de l'échantillon étudié avec une erreur relative inférieure à 6% par rapport aux mesures expérimentales, validant ainsi les modèles théoriquesThe conventional heat transfer models are not sufficiently suitable for thermal characterization of bio-sourced thermal insulating materials due to their strongly hydrophilic nature. The proposed work in this PhD thesis aims to answer this problem with experimental and theoretical approaches of coupled heat-moisture transfers. In the experimental approach, a thermal insulating material based on Flax Fiber Felt (FFF) is developed and then characterized at different hygrometric conditions with an asymmetric hot plate device. The humidity diffusion characterization of the samples is done using the GAB, GDW and Park theoretical moisture adsorption isotherm models. In the theoretical approach, a physical model of heat and mass transfer is proposed. It is solved numerically, in transient 3D configuration, by the finite element method under COMSOL Multiphysics and, in transient 1D configuration, by the finite difference method under MATLAB. The Levenberg-Marquardt method coupled with the 1D transient direct model and the measured temperatures made it possible to estimate the apparent thermal conductivity of the studied sample with a relative error of less than 6% compared to the experimental measurements, thus validating the theoretical models

Повний текст джерелаАнотація:
Cette thèse de sociologie qualitative porte sur les pratiques et les significations des aménagements de l’habitat chez des couples d’individus nouvellement retraités et issus du « Baby-Boom ». Elle rend compte des dynamiques - socio-historiques, identitaires et corporelles, relationnelles et de mode de vie - qui modèlent l’expérience du « vieillir » et de l’ « habiter » de ces individus, et ce, dans une double temporalité : dans le temps présent, à travers les aménagements réalisés et/ou projetés à court terme ; dans l’avenir, à travers les aménagements réalisés par anticipation des risques liés à la vieillesse et/ou projetés à long terme. Les résultats de cette thèse montrent, d’une part, que les aménagements de l’habitat et leurs pratiques afférentes constituent les « supports » d’une transition dans le parcours de vie, pour des « êtres vieillissants sans être vieux » qui arrivent à la retraite et en même temps, au dernier tiers de leur vie. Dans le même mouvement, ils montrent comment les liens et les activités diverses de « pivots générationnels » nouvellement retraités façonnent leur habitat et leur façon d’habiter en début de retraite. D’autre part, les résultats de cette thèse donnent à voir une approche « endogène » de l’adaptation de l’habitat, à l’heure où cette question constitue un enjeu essentiel pour les pouvoirs publics et pour les individus. Cette recherche montre sur ce point comment des Baby-Boomers font preuve, via l’aménagement de leur habitat, d’un empowerment notable au sujet de leur vieillissement présent et à venir, afin de vivre et de vieillir « bien » et si possible, chez eux. Les résultats exposés donnent aussi à penser le potentiel du « confort » pour accompagner les individus issus des générations du Baby-Boom dans la prévention des risques de l’avenir et la préparation de leur vieux jours. En même temps, cette recherche invite à réfléchir à certains freins liés aujourd’hui (encore) à ces questions, tels qu’un imaginaire de la vieillesse profondément négatif, que certaines images et messages véhiculés continuent de nourrirThis thesis of qualitative sociology is about practices and meanings of home’s adaptations made by newly retired couples of Baby Boomers. It reports various dynamics – sociological, historical, physical or of identity, relationship and lifestyle - that shape the experience of "ageing" and the "housing" of these individuals, and this in two different time frames : in the present, through realized and /or short-term planned developments; in the future, through the developments made by anticipation of risks linked to the ageing and/or long-term projection. The results of this thesis show, first of all, that the adaptation of housing and related practices constitute some "supports" for this transition in the life course, and for "ageing but not old yet” people coming to retirement and entering the “last third of their life”. In the same time, they show how the relationships and the various activities of newly retired "generational pillars" shape their habitat and way of living in the early retirement period. On the other hand, the results of this thesis give to see an "endogenous" approach to adaptation of housing, at a time when this issue is a major challenge for governments and individuals. Regarding this point of view, this research demonstrates how Baby Boomers show, through the development of their habitat, a significant empowerment about their present and future ageing in order to live and age "good" and if possible, at home. The exposed results also suggest the potential of "comfort" in order to help Baby Boomers in the process of risk’s prevention, for the future and the preparation of their old years. At the same time, this research encourages to think about the obstacles that still exist on these questions, such as the deep negative perception of aging, that certain popular images and messages continue to feed

The focus of this qualitative case study was to examine the qualities and characteristics present in a successful resource family who parents high-risk teenagers. Perspectives were gathered from the resource parents, their birth children, a foster teen living in their home, and professionals that work with these resource parents. Utilizing Family Systems Theory and content analysis of the data, themes were identified as contributing to the success of this resource family. Themes identified were inclusion, communication, boundaries, humility, and a willingness to be hurt as well as positive attitude. Implications of these themes are discussed with the literature, theory, and the use of the pre-service training that resource parents are provided. A perspective was gained from both inside and outside the resource family for analysis. A discussion around implications of these findings as well as the need to explore additional areas is outlined.

Le projet FUI12 RLDO – dans le cadre duquel s’inscrit cette thèse – préconise une solution de réseau de topologie en étoile passive pour la montée en débit des réseaux domestiques. Cette solution de réseau rencontre des difficultés dans son implémentation avec la non-uniformité des puissances des ports de sortie des coupleurs multimodes. L’analyse de ce point nous a permis de comprendre que les propriétés des modes de propagation dans les éléments du réseau jouent un rôle clé dans les problèmes rencontrés. Pour caractériser la propagation dans le réseau, nous avons développé un banc de réflectométrie optique complexe dans le domaine fréquentiel. Les phénomènes limitant la sensibilité à la phase – liés en particulier à la non-linéarité du balayage en fréquence de la source laser – sont étudiés pour contribuer à une meilleure compréhension des mécanismes. Puis les performances de la mesure en intensité et en phase de l’instrument que nous avons mis en place sont testées. Nous avons aussi étudié les conditions de résolution optimales pour caractériser les modes d’un guide multimode et analysé l’incertitude sur la dispersion chromatique dans le cas où il est impossible de déterminer si on a accès à un mode ou plusieurs modes dans un diagramme de dispersion donné. Nous introduisons par la suite une méthode d’analyse temps-fréquence adaptative, permettant d’obtenir les courbes de dispersions avec une résolution optimale. Cette méthode nous a permis de montrer le caractère quasi-monomode, en condition d’excitation monomode, de la fibre multimode spéciale RLDO à 1310 nm et à 1550 nm. L’analyse de la propagation dans les fibres optiques, associée au modèle que nous avons développé pour comprendre le fonctionnement des coupleurs multimodes, a permis d’expliquer les difficultés rencontré avec les premières expérimentations de la topologie de réseau en étoile passive multimode et d’envisager des pistes de réalisation d’un prototype de réseau fonctionnelIn order to develop high capacity future-proof home network, the FUI 12 RLDO project suggests passive star network topology using multimode couplers. This topology encounters implementation difficulties due to the non-uniformity of the power distribution in the output ports of multimode couplers. Analyzing this problem shows that the properties of modes propagating in the network elements plays a key role in this non-uniform characteristics of multimode couplers. In order to characterize these modes propagating in the network, we have developed a complex optical frequency domain reflectometry (OFDR) setup. The phenomena limiting the sensitivity to the phase in OFDR – in fact, those related to the non-linear frequency tuning of the laser source - are investigated to contribute to a better understanding of the limiting mechanisms. Then we have tested the intensity and phase measurement performance of the developed setup. Later, we studied the optimal resolution conditions to characterize the modes in a multimode waveguide. We have also analyzed the uncertainty of the measurement of the chromatic dispersion of modes in case where it is impossible to determine whether one or several modes are present in a given dispersion curve. Additionally, we have introduced an adaptive time-frequency method, to obtain the dispersion curves with optimal resolution. This method allows us to show the versatility of the special RLDO multimode fiber (single-mode behavior under single-mode excitation at 1310 nm and 1550 nm). The analysis of the propagation in the optical fibers, associated with a model we have developed to study the behavior of multimode couplers, has permitted to explain encountered difficulties with the experiments of the multimode passive star network topology. This also gives insights to develop a functional prototype of network

This study evaluates the efficacy of a self-guided, low-intensity curriculum, Marriage Moments, based on Fowers' (2000) virtues model of marital quality that emphasizes friendship, generosity, justice and loyalty. The Marriage Moments program consists of a guidebook and a video that were designed to strengthen marriages during the transition to parenthood and is used in the context of a home visitation program for first-time parents. Participants in the study included 119 married couples who had recently given birth to their first child. They were assigned to either a treatment, comparison or control group. The treatment group received the Marriage Moments curriculum as well as the Welcome Baby home visitation curriculum, the comparison group only received the Welcome Baby curriculum and the control group received neither program. Data were gathered through a battery of self- and spouse-report measures given at 3-months, 4-months, and 9-months postpartum. Relationship outcome measures included in this study were the Marital Virtues Profile, Revised-Dyadic Adjustment Scale, RELATE Satisfaction subscale, Transition Adjustment Scale, Father Involvement Scale, Household Labor Scale, and Maternal Depression Scale. Despite positive evaluations of the program from participants, analyses revealed a lack of significant, positive effects for members of the treatment group. Further research is needed before reliable conclusions can be drawn about the value of a marital virtues model as a guide for low intensity intervention.

Les radicaux OH et HO2 jouent un rôle essentiel dans beaucoup de processus d'oxydation dans l'atmosphère. La dégradation d’espèces chimiques dans les conditions troposphériques est généralement initiée par la réaction avec les radicaux OH, suivie par la réaction avec l'oxygène. Dans le cadre de cette thèse, deux techniques optiques de détection d’OH et HO2 ont été appliquée à des études cinétiques et spectroscopiques. Pour cela, nous utilisons un système expérimental de photolyse laser couplée à des techniques de détection par continuous wave Cavity Ring-Down Spectroscopy (cw-CRDS, pour HO2) et Fluorescence Induite par Laser (FIL, pour OH). Ce couplage permet de mesurer les cinétiques des radicaux OH et HO2 simultanément, résolues dans le temps pour l’étude des mécanismes réactionnels. Différents systèmes chimiques ont été étudiés en utilisant ce dispositif expérimental: 1) les cinétiques de la réaction d'OH avec CH3OH et CD3OD, 2) le rendement de HO2 dans l’oxydation de SO2 initiée par OH et 3) la formation des radicaux HO2 par photoexcitation (à 248 nm) de différents hydrocarbures aromatiques (benzène, toluène, xylene et triméthyl benzène) en présence d’oxygène. Des applications spectroscopiques de la cw-CRDS pour mesurer les sections efficaces de H2O2, HONO, HO2 et DO2 dans le proche Infrarouge ont également été réaliséesOH and HO2 radicals play a vital role in many oxidation processes in the atmosphere. The degradation of volatile organic compounds under tropospheric conditions is generally induced by the reaction with hydroxyl radicals, followed by reaction with oxygen. This thesis involved the study of the mechanisms and reaction pathways of some of these reactions using an experimental system of laser photolysis coupled to Laser Induced Fluorescence (LIF, for OH) and continuous wave Cavity Ring-Down Spectroscopy (cw-CRDS, for HO2) detection techniques. The coupling of these detection techniques allowed studying the simultaneous, time resolved kinetics of OH and HO2 radicals and spectroscopic measurements for different species by the cw-CRDS technique. Different chemical systems studied using the above experimental technique include: 1) kinetics of the reaction of OH radicals with CH3OH and CD3OD, 2) HO2 yield in the OH-initiated oxidation of SO2, 3) an energy dependence study on the direct formation of HO2 radicals from the photoexcitation (at 248 nm) of various aromatic hydrocarbons (benzene, toluene, xylene or mesitylene) in the presence of oxygen. In addition the spectroscopic applications of the cw-CRDS technique have been used to measure the absorption cross-sections of selected absorption lines of H2O2, HONO, HO2 and DO2 in the near infrared region

La maladie d’Alzheimer ou apparentée (MAA) est considérée aujourd’hui comme le plus grave problème de santé du XXIème siècle, selon l’Organisation Mondiale de la Santé (2014). Il s’agit d’une maladie neurodégénérative qui a des conséquences, non seulement, sur la personne malade, mais aussi sur l’entourage familial. En France, les pouvoirs publics ont pris en considération ces constats et ont priorisé des services destinés aux aidants familiaux, entre autres avec la mise en place des différents plans Alzheimer. Néanmoins, si l'aide apportée à domicile aux couples aidant / aidé apparaît comme une nécessité, l’offre reste en deçà de l'estimation des besoins. Afin d’étudier les conditions de maintien à domicile des personnes MAA et de leur entourage, quatre méthodologies ont été utilisées. Dans la première, une analyse de textes a permis de réaliser un état des lieux sur le contexte sociopolitique en France qui favorise le maintien à domicile des personnes MAA. Puis, une recension des écrits scientifiques a fait ressortir les caractéristiques de l’adhésion des aidants à l’utilisation des aides proposées, et sur cette base nous avons engagé une réflexion en accord avec l’éthique thérapeutique en ergothérapie en 10 points spécifiques dans l’approche familiale dans le contexte de la maladie d’Alzheimer. La deuxième méthodologie est une enquête avec la technique Delphi auprès de 26 experts. Elle a mis en évidence 22 conditions nécessaires pour favoriser le maintien à domicile. La troisième méthodologie, est un questionnaire réalisé auprès de 128 aidants en Gironde pour documenter l’utilisation des services d’aide favorisant le maintien à domicile. Les résultats statistiques permettent d’identifier 5 profils d’aidants caractéristiques et d’analyser le niveau et la manière d’utiliser les aides professionnelles. Enfin, la quatrième méthodologie est celle des récits de vie. Sept entretiens ont été réalisés auprès de couples ayant un membre atteint d’une MAA. L’analyse contribue à préciser finalement les raisons du bien vivre chez soi pour ces personnes.Ces résultats apportent une meilleure connaissance des facteurs qui influencent la décision de rester ou non à domicile par les personnes MAA et leurs proches. Ils permettent d’envisager une modélisation d’intervention s’appuyant sur l’histoire du couple et sur leurs modalités d’existence afin d’optimiser au mieux les conditions d’une libre décision des personnes concernéesToday, Alzheimer's disease is one of the worst health problem in the world (World health Organisation, 2014). It is a degenerative disease which has consequences, not only on the person, but also on the family surrounding.In France, public authorities have taken in consideration these facts and prioritized services for family caregivers, for example Alzheimer plans of action. However, if the home support services seem a necessity for the couple caregiver/care-receiver, the need for support appears to be underestimated. To study the life conditions of persons with Alzheimer disease and their surrounding, four types of methodologies were used.First, a text analysis revealed that the political context in France favors home stay for people with Alzheimer disease. Then, a review of scientific texts pointed out some characteristics of caregivers’ acceptance of proposed support services. After that, a reflection on therapeutic ethics in occupational therapy pinpointed 10 specific items for a family approach to Alzheimer disease. The second methodology was a survey using the Delphi technique with 26 experts. This investigation revealed 22 conditions necessary for homecare. The third methodology used a questionnaire with 128 caregivers in the Gironde area to document the use of support services related to homecare. Statistical analysis identified five types of caregivers and the way that these persons use professional aids. Finally, the fourth methodology was life stories. Seven interviews were conducted with couples having one member with Alzheimer disease.The analysis contributes to specify the reasons related to better living at home.These findings bring a better understanding of factors that influence the decision to stay or not at home. They allow us to consider an intervention model based on the couple’s life story and the way they live. This helps us to maximise freedom of decision for life orientation

Ces travaux de thèses ont pour objectif de présenter les résultats obtenus sur l'assemblage de deux couples de matériaux métal - céramiques par thermocompression : Inconel®625 / Alumine et TZM / Carbure de silicium. Elle se place dans la continuité des résultats obtenus sur des assemblages similaires, au sein du laboratoire IRCER, en étudiant la faisabilité de liaisons direct et de liaison après préoxydation de la partie métallique. Une partie est dédiée à la compréhension du mécanisme d’oxydation de l’inconel®625 en utilisant une thermobalance à insertion à chaud. A l’aide des cinétiques obtenues, le mécanisme d’oxydation est alors proposé et les conditions de préoxydation pour la partie d’assemblage suivante ont pu être déterminées. Ensuite au cours de ce manuscrit sont rapportés les procédés utilisés et les résultats obtenus après variations de paramètres tels que la température ou le temps de palier de traitement thermique sur les assemblages des deux couples. L'absence de formation d'une interphase pour le couple Inconel®625 / Alumine et la formation d'une interphase complexe pour le couple TZM / Carbure de silicium permette de proposer deux études différentes de liaison céramique- métal. Une partie est également consacrée à la caractérisation de la liaison obtenue, dans chaque cas, afin de déterminer sa tenue et expliquer ses propriétés à l'aide de la microscopie électronique à balayage mais aussi une simulation numérique pour le couple Inconel®625 / Alumine et des tests de tractions pour le couple TZM / Carbure de siliciumThis work has for objective to present the results obtained for the ceramic-metal bonding by hot-pressing in two cases: Inconel®625 / Alumina and TZM / Silicon carbide. All the thesis take place according to the last results obtained for similar bonding, in the laboratory IRCER, by studying the feasibility of direct bonding and bonding after pre-oxidising the metal part. A part of this study is then dedicated to the oxidation behaviour of inconel®625 under CO2 using a thermobalance with a sample hot introduction. Using the oxidation kinetics obtained, the reaction mechanism is proposed and the conditions for the metal pre-oxidation determined.Then during the manuscript are presented the processes and the results obtained after variations of parameters such as temperature and the heat treatment time for the two couples of materials. The absence of inter-phase formation in the couple Inconel®625 / Alumina and the formation of a complex inter-phase in the couple TZM / Silicon carbide allow us to propose two studies with different metal-ceramic bonding.A last part is dedicated to the characterization and the understanding of the bonding obtained in each case. To explain the properties of the samples obtained we used scaning electron microscopy but also numerical simulation for the first couple Inconel®625 / Alumina and tensile test for the second couple TZM / Silicon carbide

Conselho Nacional de Desenvolvimento Científico e TecnológicoEste trabalho tem como propósito estudar a queerness de relacionamentos entre mulheres heterossexuais e homens gays no romance A Home at the End of the World, de Michael Cunningham, e no seriado de televisão Will & Grace. O objetivo é analisar tais relacionamentos do ponto de vista das personagens femininas principais Clare e Grace, respectivamente , comparando e contrastando os textos literário e televisual. A dissertação fundamenta-se nos conceitos teórico-metodológicos da teoria queer, nos quais se baseia a análise das personagens e de seus relacionamentos. Contudo, à medida que estabelece um diálogo entre um romance e um programa televisual, foi adicionado um capítulo sobre teoria da televisão. Além de fornecer uma visão geral sobre tal teoria, o capítulo mostrou-se relevante na discussão de Will & Grace. Por meio do estudo mais aprofundado da teoria queer percebe-se que queerness, ao invés de uma identidade fixa, pode ser mais bem compreendida como uma atitude de resistência às normas sociais heteropatriarcais. Portanto, apesar das aspirações convencionais de Grace e Clare, ambas agem de forma queer em várias situações, provando que queerness é um posicionamento que todos podem assumir; até mesmo os heterossexuais
The purpose of this work is to study the queerness of relationships between straight women and gay men in Michael Cunninghams novel A Home at the End of the World and in the TV sitcom Will & Grace. The intention is to analyze such relationships from the point-of-view of the main female characters Clare and Grace, respectively , comparing and contrasting the literary and televisual texts. The theoretical-methodological core of this thesis lies on the concepts of queer theory, based on which the characters and their relationships have been analyzed. However, as it establishes a dialog between a literary work and a TV show, a theoretical chapter on television theory has been added. While providing an overview of television theory, this chapter has also been really relevant in the discussion of Will & Grace. Through a deeper study of queer theory, one realizes that queerness, instead of a fixed identity, may be better understood as an attitude of resistance to heteropatriarchal social rules. Therefore, in spite of Graces and Clares conventional aspirations, they both act queerly in several situations, proving that queerness is a positionality which everyone may assume; even straight people

A nonlinear finite element model of the hot and cold rolling processes has been developed for flat rolling stock with rectangular cross section. This model can be used to analyze the flat rolling of cold and hot steel rectangular strips under a series of different parameters, providing the rolling designer with a tool that he can use to understand the behavior of the steel as it flows through the different passes.
The models developed, take into account all of the non-linearities present in the rolling problem: material, geometric, boundary, and heat transfer. A coupled thermal-mechanical analysis approach is used to account for the coupling between the mechanical and thermal phenomena resulting from the pressure-dependent thermal contact resistance between the steel slab and the steel rolls.
The model predicts the equivalent stress, equivalent plastic strain, maximum strain rate, equivalent total strain, slab temperature increase, increase in roll temperature, strip length increase, slab thickness % reduction (draft), and stripâ s velocity increase, for both the cold and hot rolling processes. The FE model results are an improvement over the results obtained through the classical theory of rolling. The model also demonstrates the role that contact, plastic heat generation and friction generated heat plays in the rolling process.
The analysis performed shows that the steel in cold rolling can be accurately modeled using the elastic-plastic (solid Prandtl-Reuss) formulation, with a von Mises yield surface, the Praguer kinematic hardening rule, and the Ramberg-Osgood hardening material model. The FE models also demonstrate that the steel in hot rolling can be modeled using the rigid-viscoplastic (flow Levy-Mises) formulation, with a von Mises yield surface, and Shidaâ s material model for high temperature steel where the flow stress is a function of the strain, strain rate, and the temperature.
Other important contributions of this work are the demonstration that in cold rolling, plane sections do not remain plane as the classic theory of rolling assumes. As a consequence, the actual displacements, velocity, and stress distributions in the workpiece are compared to and shown to be an improvement over the distributions derived from the classical theory. Finally, the stress distribution in the rolls during the cold rolling process is found, and shown to be analogous to the stress distribution of the Hertz contact problem.Master of Science

This topology encounters implementation difficulties due to the non-uniformity of the power distribution in the output ports of multimode couplers. Analyzing this problem shows that the properties of modes propagating in the network elements plays a key role in this non-uniform characteristics of multimode couplers. In order to characterize these modes propagating in the network, we have developed a complex optical frequency domain reflectometry (OFDR) setup. The phenomena limiting the sensitivity to the phase in OFDR – in fact, those related to the non-linear frequency tuning of the laser source - are investigated to contribute to a better understanding of the limiting mechanisms. Then we have tested the intensity and phase measurement performance of the developed setup. Later, we studied the optimal resolution conditions to characterize the modes in a multimode waveguide. We have also analyzed the uncertainty of the measurement of the chromatic dispersion of modes in case where it is impossible to determine whether one or several modes are present in a given dispersion curve. Additionally, we have introduced an adaptive time-frequency method, to obtain the dispersion curves with optimal resolution. This method allows us to show the versatility of the special RLDO multimode fiber (single-mode behavior under single-mode excitation at 1310 nm and 1550 nm). The analysis of the propagation in the optical fibers, associated with a model we have developed to study the behavior of multimode couplers, has permitted to explain encountered difficulties with the experiments of the multimode passive star network topology.

Cette recherche porte sur le réaménagement du modèle de féminité durant les deux décennies 1960 et 1970, en Belgique et en France. La féminité est alors déclarée en voie de disparition tout en étant omniprésente dans les débats de société. La question de la recherche est de savoir si le modèle est bouleversé ou réaménagé par des phénomènes « nouveaux » tels que le travail des femmes, la libération sexuelle ou encore le féminisme. La recherche se base sur des sources publiées, la télévision, la radio et les mémoires d’écoles sociales et d’université. La première partie est consacrée aux bases du modèle de féminité. Elle détermine ses caractéristiques au début des années 1960. Elle étudie ensuite comment le modèle est réaménagé face aux bouleversements du féminisme et se penche sur la reformulation des fondations scientifiques du modèle. Elle se termine sur l’observation des modèles de féminité belge et français face aux modèles venus d’ailleurs. La deuxième partie porte sur le réaménagement des différentes facettes traditionnelles de la féminité, à savoir les rôles de mère, de ménagère et d’épouse. Elle observe la façon dont ces facettes sont bouleversées ou non par deux facettes « émergentes », le travail et la sexualité, dont la nouveauté est questionnée au regard de l’histoire.Doctorat en Histoire, art et archéologie

Many older couples face the dilemma of one of them developing an illness that results in their ability to cope with everyday living activities. The well spouse may struggle for many years with an increasing workload, both physical and mental. Ultimately, there may come a time, when nursing home placement becomes necessary. The aim of this research was to find out what the experience was like for the wife, with a husband who is ill and faces placement in a nursing home, and to determine whether nurses could do more to help them to cope with this difficult situation. Following ethics approval, nine wives were interviewed over a period of two years. Each of the experience was unique, but there were some common problems that many of the wives mentioned. Loneliness was considered by most of the wives as being extremely upsetting, even when they were living with other people, for example their children. The absence of their partner and long term confident was noticed particularly in the evening when, in the past, they had sat down together and watched television. Other reactions included guilt, grief, depression and a change in the husband/wife relationship. Many of the wives seemed to accept the situation, realising that they could no longer cope with their husband at home, they were also healthier than they had been when their husband was at home. This research has highlighted some important points when a wife finds herself in the situation of having to place her husband in a nursing home, although nurses are unable to assist with many of the effects on the wife of the placement, it is helpful to know that the friendliness of the staff, the care of the patient and the cleanliness and homeliness of the nursing home are helpful at this time

L’apport de fer est essentiel pour la plupart des organismes vivants, incluant la majorité des bactéries pathogènes. Cependant, le fer libre est toxique : il est lié à des protéines de stockage et de transport (e.g. ferritine, hémoprotéines…) et voit son homéostasie finement régulée. Afin d’extraire le fer de ces protéines, les bactéries utilisent divers systèmes tels que des protéines de surface ou encore des sidérophores. Bacillus cereus est une bactérie Gram-positive sporulante, pathogène opportuniste chez l’homme, 2ème cause en France de toxi-infection alimentaire collective. Chez B. cereus, la protéine de surface IlsA et le sidérophore bacillibactine (BB) sont impliqués dans l’acquisition du fer de la ferritine exogène et elles sont importantes pour l’infection de l’insecte modèle Galleria mellonella. Mes travaux présentaient deux parties : tout d’abord, l’étude de l’import du complexe BB-Fe3+ dans la cellule par FeuA, protéine de liaison de ce complexe à la surface de la bactérie, souligne le rôle central du couple BB-FeuA. La délétion des gènes codants pour ces deux molécules limite l’acquisition par B. cereus du fer de la ferritine, de l’hème, de l’hémoglobine et du fer inorganique in vitro. En revanche, elle présente un phénotype de virulence in vivo comparable à la souche de référence dans le cas d’injection intra-hémocœlique de larves de G. mellonella. Ce résultat surprenant suggère un probable rétrocontrôle sur l’expression de facteurs de virulence lorsque B. cereus ne produit ni BB ni FeuA, et se trouve par conséquent fortement carencé en fer. Le second volet de mes travaux s’intéresse à l’expression des gènes liés à l’homéostasie du fer in vivo, au cours de l’infection de l’intestin de larves de G. mellonella axéniques. Nous avons choisi une approche de type microgénomique, en prélevant les échantillons par microdissection laser, sur de façon à prélever de petits échantillons dans une zone définie, puis en analysant l’expression de quelques gènes ciblés par RT-qPCR et ddPCR à 3h et 16h post ingestion. Nos résultats montrent que : i) la colonisation intestinale de G. mellonella est impactée lorsque B. cereus est dépourvu du couple BB-FeuA ; ii) ilsA est exprimé lors de l’infection intestinale ; iii) les gènes ciblés impliqués dans l’homéostasie du fer sont activés dès le début de l’infection, suggérant un rôle dans l’adaptation et la pathogénicité ; iv) une faible modulation de l’expression est observée entre les deux temps. Ces travaux ouvrent de nouvelles connaissances fondamentales sur l’homéostasie du fer et des perspectives quant à l’utilisation de nouvelles techniques pour l’étude in situ des interactions hôte-pathogèneIron acquisition is essential for most living organisms, including many pathogenic bacteria. However, free iron is toxic: it is bound into storage or transport proteins (e.g. ferritin, hemoproteins…) and iron homeostasis is tightly regulated. To scavenge iron from these sources, bacteria possess several systems to acquire the bound iron, by surface proteins or siderophores. Bacillus cereus is a sporeforming Gram-positive bacterium, opportunistic human pathogen, 2nd cause of food-borne disease in France. It has been demonstrated that the B. cereus surface protein IlsA and the siderophore bacillibactin (BB) are involved in iron acquisition from ferritin and that these two molecules are important for infection of the insect model G. mellonella. My thesis project focused on two parts: first the study of the BB-Fe3+ complex import into the cell by the siderophore binding protein FeuA highlights the central role of both BB and FeuA. The deletion of the genes encoding for these two molecules limits iron acquisition by B. cereus from ferritin, heme, hemoglobin and inorganic iron in vitro. On the other hand, the virulence phenotype during intra-haemocelic infection of G. mellonella is similar to the Wild-type strain. These results suggest a possible feedback on the expression of virulence factor genes when B. cereus is unable to synthetize both BB and FeuA, and therefore are under high stress. The second part of my work focused on the expression of genes involved in iron homeostasis in vivo, during gut infection of germ-free larvae of G. mellonella. We chose to perform a microgenomic approach, using laser-capture microdissection to get small samples in targeted areas, and then analysing the expression of chosen genes by RT-qPCR and ddPCR at two time points post ingestion The results show that : i) the colonisation of G. mellonella gut is impacted when B. cereus is deprived of both BB and FeuA ; ii) ilsA is expressed during gut infection ; iii) iron homeostasis is involved in adaptation and pathogenicity from the early step of infection of the insect gut ; iv) only weak gene expression modulation occured between the two timepoints This work gives new fundamental knowledge about B. cereus iron homeostasis, and highlights the use of new techniques regarding the in situ study of host-pathogen interactions

Pendant les deux dernières décennies, les technologies de réseaux ad-hoc de véhicules (VANETs : Vehicular Ad-Hoc Networks) ont été développées sous l’impulsion du monde de la recherche comme de l’industrie, étant donnés les liens des VANETs avec la sécurité routière, l’internet des objets (IoT/WoT : Internet of Things/Web of Things) pour les systèmes de transport intelligents (ITS : Intelligent Transportation Systems), les villes intelligentes et les villes vertes. Composant essentiel des VANETs, les protocoles de communication inter-véhicules (IVC : Inter-Vehicle Communication) font face à des défis techniques, en particulier à cause de la diversité des applications dans lesquelles ils sont impliqués. Dans cette thèse, après une présentation des VANETs et de l’état de l’art des IVC, nous proposons un protocole de dissémination de données, TrAD, conçu pour diffuser de manière efficiente des messages d’une source vers les véhicules présents dans la zone d’intérêt (ROI : Range of Interest). TrAD se base sur les états du trafic routier et du trafic réseau pour adapter localement la stratégie et les paramètres de transmission des données afin d’optimiser les performances des applications qui l’utilisent. De plus, un algorithme de classification des clusters locaux de véhicules est conçu pour permettre l’usage de TrAD sur autoroute aussi bien qu’en ville. Pour éviter l’encombrement des canaux de communication, un mécanisme illustratif de contrôle de la congestion reposant sur une approche distribuée est utilisé. Trois protocoles IVC de l’état de l’art ont été comparés à TrAD dans des scénarios réalistes de simulation, basés sur différentes villes réelles, différents trajets et densités véhiculaires. Les performances de TrAD surpassent celles des protocoles de référence en termes de taux de délivrance des paquets (PDR : Packet Delivery Ratio), nombre de transmissions et latence. De plus, nous montrons que TrAD est tolérant, dans une certaine mesure, aux erreurs sur les données GPS. Pour s’assurer de la qualité des simulations, nous avons étudié le modèle de déplacement employé dans le simulateur de trafic, puis couplé ce dernier au simulateur de réseau, afin que les deux s’échangent des informations en temps-réel. Grâce à la compréhension acquise lors de l’analyse du modèle de déplacement, nous avons pu développer un simulateur de conduite de tramway pour la T2C (Transports en Commun de l’agglomération Clermontoise). Des tests menés sur le matériel roulant nous ont permis d’élaborer des modèles de déplacement fidèles correspondants aux diverses situations rencontrées par le tramway. L’affichage de la simulation est assuré par un flux vidéo ajusté plutôt que des images de synthèse, ce qui permet de limiter le coût de développement tout en garantissant un certain réalisme dans l’affichage. Ce projet est soutenu par la T2C pour une durée de deux ansIn the last two decades, Vehicular Ad hoc Network (VANETs) were developed significantly by both academic institute and industries association, since VANETs originate from traffic safety and are also an important application of Internet of Things / Web of Things (IoT/WoT) for Intelligent Transportation System (ITS), Intelligent Vehicles and Smart Cities. As an essential component of VANETs, Inter-Vehicle Communication (IVC) protocols face many critical challenges, in particular, because they relate to various specific applications. In this thesis, after elaborating on related knowledge of VANETs and state-of-the-art of IVC protocols, we propose a data dissemination protocol for vehicular networking, named TrAD, to disseminate efficiently warning messages from a source to vehicles in a range of interest (ROI). TrAD considers the status of road traffic and network traffic to adapt locally the strategy and the parameters of transmissions in order to optimize the global performance of IVC application. Moreover, a local vehicular cluster classification algorithm is designed to support TrAD to be performed in both highway and urban scenarios. In addition, an illustrative congestion control mechanism is used to avoid channel congestion using a distributed approach. Three state-of-the-art IVC protocols have been compared with TrAD by means of realistic simulations. The performance of all those protocols is evaluated quantitatively in various scenarios by taking into account different real road maps, trafic routes and vehicular densities. Compared with the reference protocols, TrAD gains an outstanding overall performance in terms of packet delivery ratio, number of transmissions and delay. Furthermore, TrAD also can tolerate a reasonable degree of GPS drift while achieving efficient data dissemination. In order to ensure the quality of simulations, we deeply investigated the mobility model of road traffic simulator, and then performed the bidirectionally coupled simulation in which the network simulator and the road trafic simulator can exchange information in real-time. Upon understanding of the mobility model, we obtained a chance to develop a low-cost tram simulator for the local public transportation provider, the T2C (Transports en Commun de l’agglomération Clermontoise). We attempt to design accurate mobility models from different scenarios for the specific type of tram used by T2C. Real world trials are carried out to explore the key parameters required by theoretical deduction for our mobility model. Moreover, the display GUI relies on a video stream, rather than 3D graphics, which can reduce the cost while guaranteeing the quality of service. This project was supported for two years by T2C

Previous issue date: 2009-11-10The expressive growth of the senior population is a world phenomenon. Their reflexes had beginning in Brazil starting from the second half of the century XX and it was resulted of the reduction in the fertility/mortality taxes, of the urbanization and of the increase of the life expectancy of the people. In the same way as there is the increase of the number of senior people, there is also a crescent disputes for new manners of living. Such fact lifts inherent questions of social stamp when living of the seniors in the Institutions of Long Permanence (ILPI), fear of this research, that he/she had as objective lifts the residents' of the Instituição Assistencial Nosso Lar, in Santo André-SP and to know the moments for two lived by the couples there residents, contributing to the implementation of public politics of home for senior. For so much he/she was employee the method of qualitative approach, using the interview semi-structured to pick four resident seniors' depositions in the researched Institution. We observed that the relationships to two in the Institution are permeated of prejudices so much on the part of the administration, that is not prepared to welcome seniors' couples, as on the part of the other interns, that you/they act with strangeness due to the rare moments of affectivity of the couples. It was also noticed a retraction on the part of the subjects interviewees in relation to the questions about the sexuality, once they became shy when verbalizing their moments of intimacy. We noticed that this is a theme that it still lacks studies more deepened and of operationalization of Public Politics of house for seniors so that these subjects have his/her respected citizenship when they choose an ILPI as home and place to live to two
O crescimento expressivo da população idosa é um fenômeno mundial. Seus reflexos tiveram início no Brasil a partir da segunda metade do século XX e foi resultado da redução nas taxas de fertilidade/mortalidade, da urbanização e do aumento da expectativa de vida das pessoas. Do mesmo modo como há o aumento do número de pessoas idosas, há também uma crescente demanda por novos modos de morar. Tal fato levanta questionamentos de cunho social inerentes ao morar dos idosos nas Instituições de Longa Permanência (ILPI), tema desta pesquisa, que teve como objetivo levantar o perfil dos residentes da Instituição Assistencial Nosso Lar, em Santo André SP e conhecer os momentos a dois vividos pelos casais ali residentes, contribuindo para a implementação de políticas públicas de moradia para idosos. Para tanto foi empregado o método de abordagem qualitativa, utilizando a entrevista semi-estruturada para colher depoimentos de quatro idosos residentes na Instituição pesquisada. Observamos que os relacionamentos a dois na Instituição são permeados de preconceitos tanto por parte da administração, que não está preparada para acolher casais de idosos, quanto por parte dos outros internos, que agem com estranhamento diante dos raros momentos de afetividade dos casais. Notou-se também uma retração por parte dos sujeitos entrevistados em relação aos questionamentos sobre a sexualidade, uma vez que se acanharam ao verbalizar seus momentos de intimidade. Percebemos que este é um tema que ainda carece de estudos mais aprofundados e de operacionalização de Políticas Públicas de habitação para idosos para que estes sujeitos tenham sua cidadania respeitada no momento em que escolherem uma ILPI como moradia e local para viver a dois

Syftet med denna studie var att ta reda på om en kortare massage i hemmet kan bidra med stressreducering hos kärlekspar och om en instruktionsvideo för att lära ut massage kan vara en bra metod. En kvalitativ och kvantitativ ansats har använts, även kallat mixed methods. Deltagarna var 18 personer, som alla ingick i kärleksrelationer. Inledningsvis fick de titta på en inspelad kort informationsvideo om massage för att sedan med stöd av en inspelad 20 minuter lång instruktionsvideo massera varandra på rygg och nacke. Före och efter att de gett och fått massage, skulle de också svara på en webbenkät. Resultaten från enkäten visade att stressnivån sjönk hos både de som gett (p=0,0463) och de som fått (p=0,001) massage. Av de som fått massage kände alla sig avslappnade efteråt och majoriteten (83,3%) kände sig lugna. De som gett massage kände sig även de mer lugna (77,8%) efteråt. Ingen av deltagarna uppgav att de kände sig stressade efter massagen. En instruktionsvideo visade sig, genom svaren från webbenkäten, vara en bra metod för att lära ut massage till kärlekspar.The aim of this study was to find out if a shorter massage at home can contribute to stress reduction in love couples and if an instructional video for teaching massage can be a good method. A qualitative and quantitative approach has been used, also called mixed methods. The participants were 18 people, all of whom were involved in love relationships. Initially, the participants had to watch a recorded short information video about massage and then, with the support of a recorded 20-minute instructional video, massage each other on the back and neck. Before and after giving or receiving a massage, they also had to respond to an online survey. The results from the survey showed that the stress level decreased in both those who gave (p = 0.0463) and those who received (p = 0.001) massage. Of those who received massage, all felt relaxed afterwards and the majority (83.3%) felt calm. Those who gave massages also felt calmer (77.8%) afterwards. None of the participants stated that they felt stressed after the massage. An instructional video proved, through the answers from the web survey, to be a good method for teaching massage to love couples.

Little is known about the outward trafficking of receptor dimers from the endoplasmic reticulum to the plasma membrane, or the role that trafficking plays in assembly, targeting and specificity of receptor signalling. Bimolecular fluorescence complementation was used to follow prescribed receptor homo/heterodimers in Jurkat cells and clarify the trafficking itineraries those receptors follow to reach the plasma membrane. Chemokine receptors CXCR4 and CCR5 were chosen due to their implication in numerous pathologies including, HIV and cancer, and their ability to form homo and hetero-oligomers. This study demonstrates that although the individual receptors composing heterodimeric complexes are the same as in homodimeric complexes, the heterodimer traffics and signals independently of its constituent homodimers. The presence of CD4 affects the trafficking of CCR5 containing dimers but not the CXCR4 homodimer. These observations demonstrate the importance of considering receptor heterodimers as distinct signalling entities that should be more carefully and individually characterized.

Includes bibliographical references (leaves 193-206)This thesis describes a family variation among urban Nigerian couples called a commuter marriage. A commuter marriage in this study is defined as a union between a dual earner/dual career couple where the husband and wife have decided to live apart from each other due to work commitments until such a time as is convenient for them to live continuously together again. This separation is mainly undertaken to improve their financial and career prospects. The study seeks to understand what dynamics are involved in a commuter marriage in Jos, Plateau State. The Life Course Perspective, with a focus on the gendered life course perspective, serves as a theoretical framework for this study. The perspective assumes that families undergoing the same transitions are likely to display the same characteristics which may not be necessarily relevant for all families in the same life stage, while the gendered life course perspective acknowledges the gendered context. At the same time the cultural context of the Nigerian society in terms of family norms are taken into account. An overview of commuter marriages, including characteristics of commuter marriages and non-traditional marriages linked to commuter marriages are provided. The differences between established and adjusting couples were repeatedly underlined. The research has an underlying interpretivist paradigm, therefore a qualitative research methodology was deemed best for the study. A semi-structured interview guide and time diaries were used to obtain data from seventeen participants. It was found that a commuter marriage is costly financially, socially and emotionally. An emphasis on the male provider and the wife as the manager of the resources was highlighted. Commuter couples report that their greatest support system constitute their family members who show the most understanding to their situation. Commuter fathers were generally passionate about their fatherly roles, but had conflicting feelings about balancing work and family, feeling the family is losing out. Generally, commuter couples in this study showed a sincere desire for the commuting relationship not to span an indefinite amount of time.

Dissertação de Mestrado em Engenharia Informática apresentada à Faculdade de Ciências e Tecnologia da Universidade de CoimbraInternet of Things (IoT) is a concept that recently became mainstream with the launch of numerous consumer products, some of them dedicated to Home Energy Management. Due of its novelty and immaturity, IoT Platforms should be designed for change. This project aimed to provide an existing data analysis mechanism as a service to third-parties and enable the usage of custom energy management devices by an existing data monitoring application. To achieve this, a service-oriented system was created that allows third-parties to send energy consumption data and receive the classi cation's result as soon as possible, in isolation of the remaining system; an IoT communication protocol was used to allow energy management devices to send data in degraded network conditions and with low power consumption. This solution enables future projects of the company to reuse its components, such as the generic time-series storage platform developed in the process.

Le nombre d'unions où les deux conjoints n'ont pas la même langue maternelle est en augmentation depuis les dernières décennies au Québec. Sachant que les enfants issus de ces unions gravitent dans un univers familial plurilingue, l'objectif de ce mémoire est de connaître les langues qui leur sont transmises.
En utilisant les données du questionnaire long du recensement canadien de 2006, nous avons procédé à différentes analyses descriptives nous permettant de cerner les langues maternelles véhiculées aux enfants issus d'une union mixte, de vérifier si ces enfants héritent davantage de la langue maternelle de leur mère ou de leur père et s'ils opèrent des substitutions linguistiques avant l'âge de 18 ans, c'est-à-dire si leur langue maternelle diffère de leur langue d'usage. De plus, par le biais de régressions logistiques, nous avons étudié les déterminants contextuel, ethno-culturel et socio-économique les plus susceptibles d'expliquer le choix de la langue transmise aux enfants.
Les résultats obtenus démontrent la place prédominante des langues officielles canadiennes, au détriment des langues non officielles, chez les familles exogames. De plus, le choix de la langue maternelle transmise s'avère principalement conditionné par le lieu de résidence, le parcours migratoire des parents et le pays de naissance des enfants.The number of unions where both partners do not share the same mother tongue has grown substantially over the last decades in Quebec. Given that children born to these unions live in a multilingual family setting, the purpose of this research is to study the mother tongue transmitted to these children. Using the 2006 Canadian census long-form questionnaire, we first conducted various descriptive analyses. These were intended to identify the mother tongue transmitted to children born to mixed-language unions, to ascertain whether children inherit either their mother or father's mother tongue, and to determine if a language shift occurs before the age of 18 years old, in other words whether their mother tongue differs from the principal language they use at home. In addition, through logistic regressions, we examined the contextual, ethnocultural and socioeconomic determinants explaining the choice of the language transmitted to children. The results show the predominance of the two official Canadian languages in mixed-language families, at the expense of non-official languages. Furthermore, the choice of the mother tongue transmitted is mainly conditioned by the place of residence, the parent's migration path and the children's birthplace.

Die Thrombozytenaktivierung und –adhäsion sowie die nachfolgende Thrombusbildung ist ein essentieller Prozess in der primären Hämostase, der aber auch irreversible Gefäßverschlüsse und damit Herzinfarkt oder Schlaganfall verursachen kann. Erst kürzlich wurde beschrieben, dass der C-type lectin-like receptor 2 (CLEC-2) auf der Thrombozytenoberfläche exprimiert wird, jedoch wurde für diesen Rezeptor noch keine Funktion in den Prozessen der Hämostase und Thrombose gezeigt. In der vorliegenden Arbeit wurde die Rolle von CLEC-2 in der Thrombozytenfunktion und Thrombusbildung im Mausmodel untersucht. In dem ersten Teil dieser Arbeit konnte gezeigt werden, dass die Behandlung von Mäusen mit dem neu generierten monoklonalen Antikörper INU1, der gegen murines CLEC-2 gerichtet ist, zu dem vollständigen und hochspezifischen Verlust des Rezeptors in zirkulierenden Thrombozyten führte, ein Prozess, der als „Immundepletion“ bezeichnet wird. Die CLEC-2-defizienten Thrombozyten waren nicht mehr durch den CLEC-2-spezifischen Agonisten Rhodozytin aktivierbar, während die Aktivierung durch alle anderen getesteten Agonisten nicht beeinträchtigt war. Dieser selektive Defekt führte unter Flussbedingungen ex vivo zu stark verminderter Aggregatbildung der Thrombozyten. Außerdem zeigten in vivo-Thrombosestudien, dass die gebildeten Thromben instabil waren und vermehrt embolisierten. Infolgedessen war die CLEC-2 Defizienz mit einem deutlichen Schutz vor arterieller Thrombose verbunden. Außerdem ließ die in INU1-behandelten Mäusen beobachtete variable Verlängerung der Blutungszeit auf einen moderaten hämostatischen Defekt schließen. Diese Ergebnisse zeigen zum ersten Mal, dass CLEC-2 in vitro und in vivo signifikant zur Thrombusstabilität beiträgt und eine essentielle Rolle in der Hämostase und arteriellen Thrombose spielt. Daher stellt CLEC-2 eine potentiell neue antithrombotische Zielstruktur dar, die in vivo inaktiviert werden kann. Diese in vivo-Herabregulierung von Thrombozytenoberflächenrezeptoren könnte einen vielversprechenden Ansatz für zukünftige antithrombotische Therapien darstellen. Der zweite Teil dieser Arbeit behandelte den Effekt einer Doppelimmundepletion der immunoreceptor tyrosine-based activation motiv (ITAM)- und hemITAM-gekoppelten Rezeptoren Glykoprotein (GP) VI und CLEC-2 auf Hämostase und Thrombose mittels einer Kombination der GPVI- beziehungsweise CLEC-2-spezifischen Antikörper JAQ1 und INU1. Eine Einzeldepletion von GPVI oder CLEC-2 in vivo beeinträchtigte nicht die Expression und Funktion des jeweils anderen Rezeptors. Eine gleichzeitige Behandlung mit beiden Antikörpern führte jedoch zu dem nachhaltigen Verlust der GPVI- und CLEC-2-vermittelten Signale in Thrombozyten, während andere Signalwege nicht betroffen waren. Im Gegensatz zu den Einzeldefizienzen, wiesen die GPVI/CLEC-2 doppeldefizienten Mäuse einen schwerwiegenden Blutungsphänotyp auf. Außerdem führte die Behandlung zu einer starken Beeinträchtigung der arteriellen Thrombusbildung, die die Effekte der Einzeldefizienzen weit übertraf. Von Bedeutung ist auch, dass gleiche Ergebnisse in Gp6-/- Mäusen gefunden wurden, die mittels INU1-Behandlung CLEC-2-depletiert wurden. Dies veranschaulicht, dass der Blutungsphänotyp nicht durch Sekundäreffekte der kombinierten Antikörperbehandlung hervorgerufen wurde. Diese Daten deuten darauf hin, dass GPVI und CLEC-2 sowohl unabhängig voneinander als auch gleichzeitig in vivo von der Thrombozytenoberfläche herabreguliert werden können und lassen unerwartete redundante Funktionen der beiden Rezeptoren in Hämostase und Thrombose erkennen. Da beide Rezeptoren, GPVI und CLEC-2, als neue antithrombotische Zielstrukturen diskutiert werden, könnten diese Ergebnisse wichtige Auswirkungen auf die Entwicklung von anti-GPVI oder anti-CLEC-2-basierenden Antithrombotika habenPlatelet activation and adhesion results in thrombus formation that is essential for normal hemostasis, but can also cause irreversible vessel occlusion leading to myocardial infarction or stroke. The C-type lectin-like receptor 2 (CLEC-2) was recently identified to be expressed on the platelet surface, however, a role for this receptor in hemostasis and thrombosis had not been demonstrated. In the current study, the involvement of CLEC-2 in platelet function and thrombus formation was investigated using mice as a model system. In the first part of the thesis, it was found that treatment of mice with a newly generated monoclonal antibody against murine CLEC-2 (INU1) led to the complete and highly specific loss of the receptor in circulating platelets (a process termed “immunodepletion”). CLEC-2-deficient platelets were completely unresponsive to the CLEC-2-specific agonist rhodocytin, whereas activation induced by all other tested agonists was unaltered. This selective defect translated into severely decreased platelet aggregate formation under flow ex vivo; and in vivo thrombosis models revealed impaired stabilization of formed thrombi with enhanced embolization. Consequently, CLEC-2 deficiency profoundly protected mice from occlusive arterial thrombus formation. Furthermore, variable bleeding times in INU1-treated mice indicated a moderate hemostatic defect. This reveals for the first time that CLEC-2 significantly contributes to thrombus stability in vitro and in vivo and plays a crucial role in hemostasis and arterial thrombosis. Thus, CLEC-2 represents a potential novel anti-thrombotic target that can be functionally inactivated in vivo. This in vivo down-regulation of platelet surface receptors might be a promising approach for future anti-thrombotic therapy. The second part of the work investigated the effect of double-immunodepletion of the immunoreceptor tyrosine-based activation motif (ITAM)- and hemITAM-coupled receptors, platelet glycoprotein (GP) VI and CLEC-2, on hemostasis and thrombosis using a combination of the GPVI- and CLEC-2-specific antibodies, JAQ1 and INU1, respectively. Isolated targeting of either GPVI or CLEC-2 in vivo did not affect expression or function of the respective other receptor. However, simultaneous treatment with both antibodies resulted in the sustained loss of GPVI and CLEC-2 signaling in platelets, while leaving other activation pathways intact. In contrast to single deficiency of either receptor, GPVI/CLEC-2 double-deficient mice displayed a dramatic hemostatic defect. Furthermore, this treatment resulted in profound impairment of arterial thrombus formation that far exceeded the effects seen in single-depleted animals. Importantly, similar results were obtained in Gp6-/- mice that were depleted of CLEC-2 by INU1-treatment, demonstrating that this severe bleeding phenotype was not caused by secondary effects of combined antibody treatment. These data suggest that GPVI and CLEC-2 can be independently or simultaneously down-regulated in platelets in vivo and reveal an unexpected functional redundancy of the two receptors in hemostasis and thrombosis. Since GPVI and CLEC-2 have intensively been discussed as potential anti-thrombotic targets, these results may have important implications for the development of novel, yet save anti-GPVI or anti-CLEC-2-based therapies
