Full textAbstract:
[No copyright notice] Background: Moderate and chronic consumption of red wine protects against cardiovascular disease. Wine is a complex matrix containing multiple molecules whose concentrations can vary from one bottle to another. Therefore, the delineation of the putative cardioprotective components in wine such as alcohol, resveratrol and melatonin is very challenging when using commercially available red wine. Aim: We aimed to use synthetic wine, whose composition is well characterized, to explore whether the presence of alcohol, resveratrol and melatonin (as found in commercial wines) contributes to the cardioprotective effect of chronic and moderate consumption of red wine (equivalent to 2 glasses of wine/day) in an animal model. Additionally, we hypothesized that synthetic wine enriched with resveratrol and melatonin confers cardioprotection via improvement of overall antioxidant profile.

Main Project abstract Objectives: Bitterness has been suggested to be a common psychological reaction to persistent adversity; however it has thus far been understudied. The objectives of the current study were therefore to: i) Develop a reliable and valid English language measure of bitterness, ii) Pilot this new measure within a clinical population, iii) Explore how the construct of bitterness relates to treatment outcome in psychological therapy, and iv) Determine whether bitterness accurately predicts suicidal ideation in clinical populations. Design: a cross sectional questionnaire design was used. Method: A new bitterness measure was developed incorporating ideas from existing literature and suggestions from experienced clinicians. This measure was completed by a non clinical group (n = 313) and factor analysis was carried out on these data. The measure was then completed by a group of secondary care mental health service users (n = 31) and compared with the non clinical sample,. Additional symptom focussed measures were also completed by the clinical group. Results: Factor analysis showed that the bitterness measure was comprised of four subscales (labelled here as “experience of a negative event”,” nihilism”, “unfairness” and “negative interpersonal experiences”). Good internal consistency and acceptable test-retest reliability was found. Bitterness was found to be related to rumination, in particular the brooding / analytical subtype of rumination. A significant relationship was found with some measures of anger, but no significant relationship was found between bitterness and depression. Conclusions: Bitterness may be a unique construct, conceptually distinct from anger and depression and closely associated with analytical rumination. Service Improvement Project abstract Objective: The birth of a pre-term baby is an acutely stressful event for parents. Medical advances in the UK mean that more babies than ever before are requiring NICU care. Consideration of the psychological needs of parents will help them cope with the NICU environment, develop a bond with their baby and will create the best possible outcome for NICU babies. The study objective was therefore to interview parents in order to better understand factors which supported coping. Design: A consecutive sample of NICU parents participated in semi-structured interviews which focussed on their experience. Setting: A Level 2 NICU in the UK which had recently been rebuilt. Participants: Nine parents representing seven families from a UK NICU. Methods: Parents participated in semi-structured interviews about their experience of NICU. Thematic analysis was used to extract key themes from the data. Results: The main theme described the Emotional Rollercoaster of NICU. Additional themes identified factors which helped or hindered coping: Baby Wellbeing, Physical Environment and Other People. Conclusion: Parents identified a number of factors affecting how they cope with the NICU experience. None of these alone explains positive coping, however the findings of this study give useful information about optimal NICU conditions to parental promote psycho-social wellbeing. Critical Literature Review abstract A substantial amount of high quality research has been conducted exploring the development and maintenance of Post Traumatic Stress Disorder (PTSD) among people who witness or are victims of traumatic events. Well validated models of the disorder have led to the development of robust and effective treatment protocols. Scant attention has however been paid to the exploration of PTSD within individuals who perpetrate violent acts. There were, therefore, two broad aims of this review. The first was to review and summarise available evidence for the existence of PTSD in perpetrators, and the second was to synthesise this evidence in order to draw conclusions regarding the development and maintenance of PTSD in perpetrators and whether existing theoretical models may be applicable to this group of people. Overall, very few studies have been published in this area. There is preliminary evidence that PTSD can develop after perpetration of a violent act and that psychological therapy for such PTSD based on a cognitive model may be effective, taking account of key emotions such as guilt and shame.

Full textAbstract:
La végétation terrestre et aquatique est soumise à une interaction forte avec l'écoulement du fluide environnant. Afin de surmonter les efforts fluides, les plantes se reconfigurent : l'écoulement provoque un changement de géométrie qui induit une réduction des efforts. Cette thèse présente un cadre théorique simple pour modéliser et comprendre les stratégies de reconfiguration par rupture et déformation. Il est montré dans ce travail que les arbres vont subir un élagage induit par le vent, ce qui constitue une stratégie de survie efficace face à des écoulements importants. Dans le cas général impliquant des déformations et de la rupture, on montre que la reconfiguration est un processus en deux temps, d'abord par reconfiguration élastique, puis par reconfiguration fragile. On obtient ainsi une caractérisation globale des stratégies de reconfiguration de plantes en fonction de leurs paramètres physiques. Un modèle homogénéisé est ensuite développé afin de généraliser le calcul de la reconfiguration de systèmes ramifiés sous écoulement. Avec ce modèle, un système ramifié est représenté par un ensemble de fibres. La formulation volumique du problème permet ainsi un couplage avec les équations du fluide, et ouvre des perspectives nouvelles pour l'étude des systèmes ramifiés en général<br>Terrestrial plants and aquatic vegetation are submitted to a strong interaction with the external fluid flow. In order to overcome the flow-induced loads, plants reconfigure: flow induces geometrical changes, thereby reducing the loads. This thesis presents a simple theoretical framework for modeling and understanding reconfiguration strategies, by deformation and breakage. It is shown that trees will undergo flow-induced pruning, which is an efficient survival strategy under important flow velocities. In the general case involving both deformation and breakage, reconfiguration is found to follow a two-step process, first elastic reconfiguration, and then brittle reconfiguration. We obtain therefore a general characterization of reconfiguration strategies in plants, depending on their physical parameters. A homogenized model is then developed in order to generalize the computation of reconfiguration of ramified systems under flow. According to this model, a branched system is represented by a bundle of fibers. The continuous formulation of this problem allows for coupling with the fluid equations, and provides new perspectives for the study of ramified systems in general

Full textAbstract:
Procrastination is the volitional delay of an intended task, despite believing that delay will be harmful. While not all delay is attributable to procrastination, procrastination is fundamentally characterised by delay. As much as 90% of the population have experience with procrastination, with around 20% in the general population and 50% of university students reporting problematic levels of chronic procrastination. Compared to their non-procrastinating peers, chronic procrastinators report lower levels of wellbeing, higher rates of depression, higher rates of alcohol and other drug use for coping, and poor health adjustment. Procrastinators tend to have lower salaries, shorter durations of employment, and a greater likelihood of being unemployed or underemployed. There is also a direct economic impact on the workforce, with office workers found to spend an average of 1.5 hours per work day procrastinating.
Despite its prevalence, the variability of tasks, time available, subjectivity, and individual differences render procrastination difficult to observe as it happens. Consequently, while correlates, antecedents, effects, and types of procrastination have been widely investigated, progress in this field is limited by several factors. In particular, few studies have accurately quantified delay associated with procrastination over time. As a consequence, there is limited evidence supporting the ability of trait measures of procrastination to predict delay, and few interventions aimed at reducing procrastination have been clearly associated with reduced delay.
Recent developments in smartphone technology and Experience Sampling Method (ESM) applications have enabled intensive longitudinal observations of such dynamic phenomena with relative ease; however, such methodology and statistical modelling of delay have yet to be reliably applied to the study of procrastination.
To address the challenge of observing delay associated with procrastination, I conducted three studies of students enrolled in a 1st year psychology course: a small pilot study (N = 24) and two larger scale replications (Ns = 80 and 107) focusing on intensive longitudinal measurement of delay, procrastination scale validation, and an intervention to reduce procrastination respectively. Participant ages ranged from 17.38 to 65.85 years (M = 23.85, SD = 9.49) and 75% identified as female. Each study included a baseline survey of demographic and trait procrastination and personality variables, an ESM phase comprised of 28 SMS surveys over 14 days in the lead-up to submission of an assignment worth 30% of the course grade, and the collection of assignment submission date and mark from the course convenor. Participants in the ESM phase were randomly allocated into either an intervention or control condition, with participants in both conditions reporting their assignment progress, completion intent, and affect regarding their assignment progress. Participants in the intervention, but not the control, condition were messaged at the end of each ESM survey with open reflection prompts designed to reduce procrastination. Studies 1 and 3 also included follow up interviews with a small subsample of participants (N = 8) to garner first-hand perspectives of participation in the ESM component of the studies. Through the application of multilevel model analyses, the presence of quantified delay curves in all three studies provides firm evidence that regular self-reporting of task progress using ESM is a robust and reliable method for measuring behavioural delay. The use of multilevel modelling in quantifying delay enabled the inclusion of mixed effects, where the predictive ability of several procrastination scales could be assessed. A trait measure of passive procrastination was found to reliably predict behavioural delay, whereas no association was found between a measure of active procrastination, a type of procrastination purported to be adaptive and deliberate, and delay. The intervention prompting regular reflection on factors thought to be related to procrastination that was embedded into the ESM phase of each study was found to significantly reduce delay in Studies 1 and 3, but not in Study 2. Between-study differences in this intervention effect were likely related to contextual differences as participants in Study 2 were aware that the research pertained to procrastination whereas those in the other studies were not informed of the focus on procrastination. In the follow-up interviews, participants reported that regularly reporting task progress, as well as the intervention reflection prompts, may have assisted with the reduction of procrastination. Analyses conducted into the relationships between trait procrastination, neuroticism, and state affect and delay revealed that neuroticism (emotional stability) moderated the relationship between trait procrastination and affect, and affect mediated the relationship between trait procrastination and task delay. Moreover, cross-lagged panel model analyses of inter-temporal changes in affect and delay showed that participants who reported greater task progress at an earlier time were likely to report higher positive affect at a subsequent time, whereas those reporting higher positive affect at an earlier time tended to report lower progress at a subsequent time.
Overall, the research offers three specific unique contributions to the body of knowledge. First, the use of ESM surveys of task progress is demonstrated to be a reliable method for measuring behavioural delay associated with procrastination. This is evidenced by the presence of accelerating delay curves, where assignment progress increases in a hyperbolic trajectory prior to a submission date. The reliable observation and modelling of delay is an oft-cited limitation of the field; thus, the replicated validation of this as a reliable method constitutes a valuable contribution. Second, multilevel mixed effects modelling is used to assess the ability of scales measuring different aspects of trait procrastination to predict behavioural delay, indicating that some trait procrastination measures are more predictive of behaviour than are others. The statistical method employed, and the use of task progress rather than study duration as the outcome, enabled the construct validity of the contentious ‘active’ form of procrastination to be challenged. This approach is proposed also to be a suitable method for assessing the behavioural efficacy of targeted interventions for reducing procrastination. Third, sending regular reflection prompts to randomly selected ESM recipients resulted in a significant reduction in behavioural delay in two of the three studies. This use of low-intensity reflection prompts delivered at a high-frequency demonstrates smartphone use can be an effective medium for reducing procrastination without the need for intensive approaches requiring considerable commitment from both practitioners and participants. This intervention design sets an example for reducing delay in academia, with the method likely capable of being extended, with adaptation, to procrastination in other areas such as health behaviour change, personal finance, and collective action.<br>Thesis (Professional Doctorate)<br>Doctor of Philosophy in Organisational Psychology (PhD OrgPsych)<br>School of Applied Psychology<br>Griffith Health<br>Full Text

Full textAbstract:
Bio-deterioration of concrete, which is very common in sewer system and waste water treatment plant, results in significant structure degradation. Normally, the process can be described by the two following parts: 1) Biochemistry reactions producing biogenic aggressive species in biofilms which are spread on the surface of concrete. As one of the most significant biogenic acid in sewer pipes, sulfuric acid (H2SO4) is produced by sulfur oxidizing bacteria (SOB). 2) Chemical reactions between biogenic aggressive species and cement hydration products which is responsible for concrete deterioration. A reactive transport model is proposed to simulate the bio-chemical and chemical deterioration processes of cementitious materials in contact with SOB and H2S or sulfuric acid solution. This model aims at solving simultaneously transport and biochemistry/chemistry in biofilms and cementitious materials by a global coupled approach. To provide an appropriate environment for SOB to grow, the surface neutralization of concrete (i.e., the absorption of H2S and aqueous H2S corrosion) is considered. To obtain the amount of biogenic H2SO4, the bio-oxidation of H2S by the activation of bacteria is simulated via a simplified model. To provide a suitable environment for SOB to grow, the abiotic pH reduction of concrete process is introduced. The production rate of H2SO4 is governed by the pH in the biofilms and the content of H2S in gas.It is assumed that all chemical processes are in thermodynamical equilibrium. The dissolution of portlandite (CH) and calcium silicate hydrates (C-S-H) and the precipitation of gypsum (C¯S H2) and calcium sulfide are described by mass action law and threshold of ion activity products. To take into account the continuous decrease of the Ca/Si ratio during the dissolution of C-S-H a generalization of the mass action law is applied. By simplifying the precipitation process of gypsum, a damage model is introduced to characterize the deterioration of concrete due to the swelling of gypsum. Thus, the porosity evolution and deterioration depth during deterioration process are taken into account. Only diffusion of aqueous species are considered. Different diffusion coefficients are employed for various ions and Nernst-Planck equation was implemented. The effect of the microstructure change during deterioration on transport properties is considered as well. For both biofilms and cementitious materials, the balance equations of total mass of each atom (Ca, Si, S, K, Cl) are used to couple transport equations and (bio-)chemical reactions. The model is implemented within a finite-volume code, Bil. Following the introduction of principle of the finite volume method, the coupling of the bio-chemistry process in biofilms and chemistry process in cementitious materials is illustrated. By this model, some experiments reported in literature, including chemical immersion tests (statical solution condition and flow solution condition) and microbiological simulation tests, are simulated. The numerical results and the experimental observations are compared and discussed. The influence of properties of cementitious materials (initial porosity, carbonated layer, etc.) and environmental factors (concentration of H2SO4, content of H2S, etc.) are investigated by this model as well. Furthermore, a long term predictionis conducted

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR<br>Neste trabalho, apresentam-se modelos mecânicos para previsão da integridade estrutural de tubulações anelásticas conduzindo líquidos, submetidas a transientes hidráulicos. A descrição do fenômeno de transiente hidráulico é feita com base em duas formulações unidimensionais: uma acoplada e outra desacoplada. A formulação acoplada considera a interação dinâmica fluido-estrutura entre os movimentos do fluido e do tubo, enquanto que a desacoplada refere-se ao modelo tradicional de golpe de ariete.
A integridade da tubulação é modelada com base na Mecânica do Dano Continuo. O comportamento anelástico da parede do tubo assim como o dano induzido pela deformação anelástica são descritos por uma teoria constitutiva com variáveis internas e forte respaldo termodinâmico. A teoria engloba um grande número de equações constitutivas encontradas na literatura e permite descrever diferentes respostas mecânicas numa mesma estrutura matemática. As equações resultantes para ambos os modelos - acoplado e desacoplado - formam um sistema não linear de equações diferenciais parciais hiperbólicas. Apesar da forte não linearidade, mostra-se que métodos numéricos clássicos podem ser empregados para resolver as equações quando se utiliza uma técnica de decomposição do operador. No trabalho, emprega-se entre outros o método de Glimm. Exemplos numéricos que retratam a evolução do dano induzida por transientes de pressão em tubulações elasto-viscopláticas são apresentados e analisados. Comparações realizadas entre as previsões dos modelos e entre simulações com e sem dano permitem, na análise, caracterizar as influências do acoplamento fluido-estrutura e do dano.<br>This work presents mechanical models for structural failure prediction of compliant inelastic pipings conveying liquids, submitted to hydraulic transients. Hydraulic transients are described based on two, a coupled and an uncoupled, onedimensional formulations. The coupled formulation takes into account the dynamical fluid-structure interaction between fluid flow and pipewall motions, whereas the uncoupled one refers to the well-known waterhammer model. Piping integrity is modelled on the basis of the Continuum bamage Mechanics. Both pipewall inelastic mechanical behavior and damage induced by inelastic deformations are described by an internal variable constitutive theory with strong thermodynamical support. It encompasses a great number of constitutive equations found in the literature and allows the treatment of several different mechanical responses within a same mathematical framework.
The resulting equations of both coupled and uncoupled transient models forma non linear system of hyperbolic partial differential equations. In spite of its strong non linearity, it is shown that classical numerical methods can be used for solving the equations whether a operator splitting technique is employed. Among others, Glimm s scheme has been used in this work. Numerical examples concerning the damage evolution induced by pressure transients in elasto-viscoplastic pipings are presented and analysed. Comparisons between the predictions of the models and simulations with and without damage are presented, so that the fluid-structure coupling and the damage influences on the analysis are investigated.

La biodétérioration du béton, très courante dans les systèmes d'égouts et de traitement des eaux usées, entraîne une dégradation significative de la structure. Normalement, le processus peut être décrit par les deux étapes suivantes : 1) Des réactions biochimiques produisent des espèces agressives dans les biofilms qui tapissent la surface du béton. L'un des plus importants acides biogéniques que l'on trouve dans les canalisations d'égout est l'acide sulfurique (H2 SO4 ) que est produit par des bactéries sulfo-oxydante (BSO)à partir de l'hydrogène sulfuré (H2 S). 2) Les réactions chimiques entre les espèces agressives biogéniques et les produits d'hydratation du ciment sont responsables de la détérioration du béton. Un modèle de transport réactif est proposé afin de simuler les processus des détériorations chimique et biochimique des matériaux cimentaires en contact avec les BSO et le H2 S ou une solution d'acide sulfurique. L'objectif de ce modèle est de résoudre simultanément le transport et la biochimie / chimie dans les biofilms et les matériaux cimentaires par une approche globale couplée. Afin de fournir un environnement approprié pour la croissance des BSO, la neutralisation de la surface du béton (i.e., l'absorption de H2 S et la corrosion aqueuse de H2 SO4 ) est considérée. Pour obtenir la quantité de H2 SO4 biogénique, la bio-oxydation du H2 S par l'activation des bactéries est simulée par un modèle simplifié. Puis, pour alimenter un environnement convenable pour la croissance des BSO, la réduction abiotique du pH du béton est introduite. Le taux de production de H2 SO4 est régi par la valeur du pH dans les biofilms et la quantité de H2 S dans le gaz. On fait l'hypothèse que tous les processus chimiques sont en équilibre thermodynamique. La dissolution de la portlandite (CH) et du silicate de calcium hydratés (C-S-H), ainsi que la précipitation de gypse (CSH2) et du sulfure de calcium sont décrites par la loi d'action de masse et le seuil des produits d'activité ionique. Pour prendre en compte la décroissante continue du rapport Ca/Si lors de la dissolution de la C-S-H, une généralisation de la loi d'action de masse est appliquée. En simplifiant le processus de précipitation du gypse, un modèle d'endommagement est introduit pour caractériser la détérioration du béton due au gonflement du gypse. Ainsi, l'évolution de la porosité et de la profondeur de la détérioration pendant le processus de dégradation sont pris en compte. Seule la diffusion des espèces aqueuses est considérée. Différents coefficients de diffusion sont utilisés pour divers ions et l'équation de Nernst-Planck est implémentée. L'effet, pendant la détérioration, de la modification de la microstructure sur les propriétés de transport est aussi considéré. Pour les biofilms et les matériaux cimentaires, les équations d'équilibre de masse totale de chaque atome (Ca, Si, S, K, Cl) sont utilisées pour coupler les équations de transport et les réactions (bio) chimiques. Le modèle est implémenté dans un code volumes finis, Bil. Grâce à l'introduction de la méthode des volumes finis, on illustre le couplage du processus bio-chimie dans les biofilms et le processus de la chimiedes matériaux cimentaires. Par ce modèle, certaines expériences rapportées dans la littérature, dont des tests d'immersion chimiques (condition de la solution statique et condition de la solution d'écoulement) et des simulations microbiologiques, sont simulées. Les résultats numériques et les observations expérimentales sont comparés et discutés. L'influence des propriétés des matériaux cimentaires (porosité initiale, couche carbonatée, etc.) et les facteurs d'environnement (concentration de H2 SO4 quantité de H2 S etc) sont aussi étudiés par ce modèle.

Boundary Element Method progress into research foR study pile groups.
This method including the non-linear conduct of the soil by a hyperbolic
modulus reduction curve; the non-linear response of rc pile section. The non-
linear behaviour of soil is modelled using a hyperbolic modulus reduction
curve; the non-linear response of rcc pile sections is modelled using a
hyperbolic modulus reduction curve, also considering tension stiffening's
impact; and the effect of suction is modelled using rising the stiffness of
shallow portions of soil. The pile group shadowing effect was analysed by a
method comparable to that suggested in the Strain Wedge Model for pile
group studies.In comparison to more complicated codes like VERSAT-P3D,
PLAXIS 3D, and FLAC-3D, the suggested BEM approach requires less
computing effort and produces accurate results utilising data from a normal
site inquiry. A study of measured and calculated result for a horizontal loaded
fixed-head pile group made up of rcc bored piles is provided . The findings of the
recommended approach are found to be quite similar to those obtained in the field.
To determine the ultimate lateral capacity and deflection under working loads,
all tests were carried out to failure. When compared to straight shaft piles
, test findings show a non linear response, a significant increase in lateral
capacity, and a reduction in deflections at working loads .

DE ENSINO<br>A utilização de materiais compósitos de matriz polimérica em plataformas de petróleo é impulsionada pela necessidade de aumentar a vida útil dos componentes em ambientes corrosivos, contribuindo para uma menor demanda de manutenção e uma maior continuidade operacional. No entanto, estes materiais têm limitações quando são expostos a altas temperaturas e esta aplicação em navios e plataformas flutuantes está sujeita às regras das Sociedades Classificadoras. Um dos requisitos é a demonstração de que as grades em compósito retêm um nível significativo de integridade mecânica após exposição a temperaturas elevadas, típica de um incêndio. No Brasil, a aplicação de grades de piso em material compósito para plataformas de petróleo teve início em meados dos anos 90. Durante os primeiros anos, estas grades eram fornecidas com matriz de resina poliéster, pois, além de atender aos requisitos de desempenho da época, tinham um custo mais favorável. Atualmente, para convés aberto, onde pessoas podem permanecer como um refúgio seguro temporário ou estações de embarque de botes salva-vidas, os critérios de segurança das Sociedades Classificadoras são mais restritivos e apenas grades de piso em resina fenólica podem ser utilizadas. Este estudo tem como objetivo avaliar o comportamento mecânico de dois materiais compósitos após exposição a uma temperatura de 250 graus Celsius. O primeiro material consiste de um compósito de matriz poliéster isoftálica e o segundo de resina fenólica, ambos reforçados com fibra de vidro. Análise termogravimétrica foi aplicada para avaliar a estabilidade térmica dos s materiais. As microestruturas foram caracterizadas pelas técnicas de microscopia óptica e microscopia eletrônica de varredura. Corpos de provas dos materiais como recebido e após degradação térmica foram submetidos a ensaios de flexão em três pontos.<br>The use of non-metallic composites floor gratings in offshore platforms is driven by the need of increased component life in corrosive environments. As a result, these floor gratings contribute to a lower demand of maintenance and greater operational continuity. However, these composite materials have limitations when are exposed to high temperatures. The application of these floor gratings on ships and floating offshore platforms is subject to the acceptance of Classification Societies rules. One of the requirements is to demonstrate that the gratings retain a significant level of mechanical integrity during and after a high temperature exposure, as a fire scenario. In Brazil, in the mid - 90s, polyester resin was chosen as matrix for composite floor gratings. Nowadays, for open decks on oil exploration platforms where groups of people are likely to assemble such as temporary safe refuge or lifeboat embarkation area, due to more restrictive safety criteria as smoke density, gas toxicity and mechanical integrity in fires, only phenolic-based gratings are acceptable. This study aims to evaluate and compare the mechanical behavior of two composite materials after being exposed to a thermal degradation. One material consists of an isophthalic polyester resin and the other of a phenolic resin. Thermogravimetric analysis was applied to evaluate the thermal stability of materials. Evaluation of flexural mechanical properties of these composites, as received and after being exposed to 250 Celsius degrees, were performed. The microstructures of the two polymeric glass fiber-reinforced composites were characterized using optical microscopy and also by scanning electron microscopy.

We consider an infinite system of hard balls in Rd undergoing Brownian motions and submitted to a pair potential with infinite range and quasi polynomial decay. It is modelized by an infinite-dimensional Stochastic Differential Equation with an infinite-dimensional local time term. Existence and uniqueness of a strong solution is proven for such an equation with deterministic initial condition. We also show that the set of all equilibrium measures, solution of a Detailed Balance Equation, coincides with the set of canonical Gibbs measures associated to the hard core potential.

Evènement rare, un incendie au sein ou à l’extérieur d’un avion peut avoir des conséquences catastrophiques pour l’intégrité de l’appareil et de ses occupants. Les aéronefs sont donc dimensionnés pour répondre aux nombreuses exigences définies par les Autorités de certification. Le respect de ces exigences doit être démontré au travers d’essais de certification sur des échantillons de dimensions réduites avec des bruleurs standardisés. Dans une démarche de virtualisation d’essais, le développement d’outils prédictifs du comportement thermophysiques des structures composites soumises à un feu est un objectif ambitieux et très prometteur. Face à la complexité des nombreux phénomènes physiques mis en jeux (thermo-dégradation, dégazage, inflammation de gaz de pyrolyse, érosion, etc.), une méthodologie de modélisation incrémentale a été suivie partant de modèles simples pour aboutir au développement d’un modèle 3D du comportement thermochimique du composite T700/M21 soumis au feu. Ce modèle est basé sur une étude phénoménologique du comportement du composite grâce au développement d’un test au feu innovant et maitrisé. En outre, toutes les données d’entrée sont issues de mesure expérimentale de propriétés thermophysiques en utilisant des méthodes de caractérisation existantes et innovantes. In fine, la comparaison des profils de température et de la perte de masse mesurés du composite avec les résultats numériques montre la capacité du modèle à prédire ce comportement au feu<br>Rare event, an aircraft in fire can lead to disastrous consequences for the integrity of the plane and its passengers. The aircraft are thus dimensioned in order to comply with the large number of requirements defined by the certification Authorities. The respect of these standards has to be demonstrated via certification tests on structure panels of reduced size using standardized burners. In a virtual testing approach, the development of predictive tools of the thermomechanical behaviour of the composite exposed to fire is an ambitious objective and very promising. With regards to the complexity of the many physical phenomena involved in the combustion process (thermodegradation, out-gassing, ignition of gases, erosion, etc.), an incremental modelling methodology has been followed starting with basic model to finally succeed to develop a 3D model of the thermochemical behaviour of the T700/M21 composite exposed to fire. This model is based on a phenomenological study of the behaviour of the composite using a novel versatile fire test which was developed in a totally controlled way. In addition, all inputs are obtained from measurements of thermophysical properties using existing and innovative characterisation methods. In fine, the comparison of the measured temperature profiles and the mass loss of the composite with the numerical results show the capability of the model to predict the fire behaviour of the material

Full textAbstract:
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior<br>The plants are frequently exposed to environmental stresses, which cause imbalances in physiological and biochemical metabolism. This work aimed to study the physiological and biochemical changes of plant forage sorghum (Sorghum bicolor) genotype CSF18, depending on the time of salt stress. The seeds were sown in vermiculite moistened with distilled water, in a greenhouse conditions, and after seven days, the seedlings were transferred to trays with Hoagland solution diluted 1:2. After seven days, treatment was established stress saline (75 mM NaCl), one group of plants kept in nutrient solution in the absence of salt (control). Samples were collected at 0, 5, 10 and 15 days after the initiation of stress. We evaluated the growth, gas exchange, contents and chlorophyll fluorescence, the concentration of organic solutes (proline, N-amino solutes, soluble carbohydrates, soluble proteins and polyamines free) and inorganic (Na+, Cl- and K+), as well as the activity of ribonuclease (RNase). We also determined the activities of catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX) and guaicol peroxidase (GPX), as well as the levels of H2O2, ascorbate and glutathione in leaves and roots. Salinity reduced plant growth, being observed reductions in leaf area, and fresh and dry weights of shoots and roots. This was related to a reduction in net photosynthesis rate, even with the transpiration rate and stomatal conductance is not affected. The salinity increased contents of Na+ and Cl- in plant tissues, but the K+ decreased. The levels of organic solutes in leaves and roots increased, particularly at five and ten days of stress. The polyamines putrescine and spermidine were found at very low levels in both leaves and roots, while spermine was not detected in any analyzed portion of the plant. Although putrescine increased in salt stress, some must have contributed to the osmotic adjustment, however, their participation in oxidative protection was suggested. The salinity increased the activity of SOD, APX and GPX and the redox state of ascorbate, especially in the leaves, and this is related to the maintenance of H2O2 levels and increased protection against oxidative damage. The CAT showed the main enzyme remover H2O2 in the leaves while the roots that role was played by GPX. The RNase activity in leaves, stems and roots of sorghum increased in stress conditions, but their role in protection against the deleterious effects of salinity is not yet fully understood. In general, the data show that the antioxidative system (enzymatic and non-enzymatic) can play a key role in the acclimation of sorghum plants to salt stress, and that the reduction of plant growth was probably due to inhibition of biochemical phase of photosynthesis, caused by accumulation of toxic ions, Na+ and Cl-, reducing the relation K+/Na+ at levels harmful to the metabolism<br>As plantas estÃo freqÃentemente expostas a estresses ambientais, os quais causam desequilÃbrios no metabolismo fisiolÃgico e bioquÃmico. Este trabalho teve por objetivo estudar as alteraÃÃes fisiolÃgicas e bioquÃmicas de plantas de sorgo forrageiro [Sorghum bicolor (L.) Moench], genÃtipo CSF 18, em funÃÃo do tempo de exposiÃÃo ao estresse salino. As sementes foram semeadas em vermiculita umedecida com Ãgua destilada, em casa de vegetaÃÃo e, apÃs sete dias, as plÃntulas foram transferidas para bandejas com soluÃÃo nutritiva de Hoagland diluÃda 1:2. ApÃs sete dias, foi estabelecido o tratamento de estresse salino (NaCl a 75 mM), sendo um grupo de plantas mantido em soluÃÃo nutritiva na ausÃncia de sal (controle). As coletas foram realizadas aos 0, 5, 10 e 15 dias apÃs o inÃcio do estresse. Avaliou-se o crescimento, as trocas gasosas, os teores e a fluorescÃncia da clorofila, os teores de solutos orgÃnicos (prolina, N-aminossolÃveis, carboidratos solÃveis, proteÃnas solÃveis e poliaminas livres) e inorgÃnicos (Na+, Cl- e K+), bem como a atividade da ribonuclease (RNase). TambÃm foram determinadas as atividades das enzimas catalase (CAT), dismutase do superÃxido (SOD), peroxidase do ascorbato (APX) e peroxidase do guaicol (GPX), bem como os teores de H2O2, glutationa e ascorbato em folhas e raÃzes. O estresse salino reduziu o crescimento das plantas, sendo observadas reduÃÃes na Ãrea foliar, e nas matÃrias fresca e seca da parte aÃrea e das raÃzes. Isto foi relacionado com a reduÃÃo na taxa de fotossÃntese lÃquida, mesmo com a taxa de transpiraÃÃo e a condutÃncia estomÃtica nÃo sendo afetadas. A salinidade aumentou os teores de Na+ e Cl nos tecidos das plantas, porÃm, diminuiu os de K+. Os teores de solutos orgÃnicos em folhas e raÃzes aumentaram, principalmente aos cinco e dez dias de estresse. As poliaminas putrescina e espermidina foram encontradas em nÃveis muito baixos tanto em folhas como raÃzes, enquanto a espermina nÃo foi detectada em qualquer dos tecidos analisados. Embora a putrescina tenha aumentado em condiÃÃes de estresse salino, pouco deve ter contribuÃdo para o ajustamento osmÃtico, contudo, foi sugerida sua participaÃÃo na proteÃÃo oxidativa. A salinidade aumentou a atividade das enzimas SOD, APX e GPX e o estado redox do ascorbato, especialmente nas folhas, sendo isto relacionado com a manutenÃÃo dos nÃveis de H2O2 e com o aumento da proteÃÃo contra os danos oxidativos. A CAT mostrou-se a principal enzima removedora de H2O2 nas folhas, enquanto nas raÃzes esse papel foi desempenhado pela GPX. A atividade da RNase, em folhas, colmos e raÃzes de sorgo aumentou em condiÃÃes de estresse, porÃm seu papel na proteÃÃo contra os efeitos deletÃrios da salinidade ainda nÃo està totalmente esclarecido. Em geral, os dados mostram que o sistema antioxidativo (enzimÃtico e nÃo-enzimÃtico) pode desempenhar papel fundamental na aclimataÃÃo das plantas de sorgo ao estresse salino e que os efeitos deletÃrios da salinidade no crescimento das plantas, devem-se, provavelmente, à inibiÃÃo da fase bioquÃmica da fotossÃntese, causada pelo acÃmulo de Ãons tÃxicos, Na+ e Cl-, reduzindo a relaÃÃo K+/Na+ a nÃveis prejudiciais ao metabolismo.

Full textAbstract:
In some industrial fields, such as aerospace, electro-hydrostatic actuators (EHAs) are increasingly used to replace conventional standard hydraulic actuators due to their better energy performance. Moreover, implementing different type or technology of actuators in redundant actuation systems working on the same moving part introduced some new challenges. This paper presents a force-tracking controller for an asymmetric electro-hydrostatic actuator that is submitted to an external motion generated by an external source. In this case, the rod displacement is considered as an external disturbance for the hydraulic cylinder, but it is assumed that this disturbance can be easily measured using sensors. The theoretical motivation of this work is discussed along and a variable gain state feedback control based on Linear Parameter Varying control (LPV) theory is proposed to achieve stability, disturbance rejection and tracking performance. The Linear Matrix Inequalities (LMI) framework is used to determine a control law including an augmented state feedback with an integral action that reduces trajectory-tracking errors. Simulation results of the control law are finally given to verify the global performance of this control design.

Full textAbstract:
In vivo, les groupes de cellules ont besoin de se déplacer de façon coordonnée pour pouvoir développer des fonctions physiologiques. Certaines cellules sont entourées d’une matrice extracellulaire, un réseau de protéines allant du nanomètre aux centaines de micromètres. Dans un tel environnement, les cellules peuvent se déplacer ensemble,guidées par l’orientation du réseau. Ce comportement a été étudié in vitro dans des systèmes simplifiés utilisant des guides de différentes tailles. Ces études montrent que la taille du guide contrôle le mouvement collectif des cellules.Cependant, ce mouvement collectif et les mécanismes associés sont encore flous dans les systèmes où coexistent des guides de plusieurs tailles.Dans cette thèse, nous avons cultivés des cellules sur des substrats présentant deux échelles de tailles: des microabrasions subcellulaires orientées selon un angle par rapport à des bandes mésoscopiques plus larges. Nous montrons que la largeur de la bande contrôle une transition d’orientation des cellules entre les deux modes de guidage,et ce, pour une largeur critique. Plus précisément, l’angle au centre dans les bandes larges est stabilisé par un effet de“contact guidance” indépendant de l’activité cellulaire, alors même que la migration collective des cellules montre un écoulement de cisaillement aux bords de la bande. Ces observations ont été reliées à un modèle théorique que nous avons développé, basé sur la matière active. De plus, en changeant l’orientation des microabrasions, nous avons mesuré le “flow-alignment parameter” pour la première fois dans de tels systèmes.Ces mécanismes généraux peuvent s’appliquer à d’autres contextes in vivo, en particulier pendant la myogénèse. En cultivant des myoblastes de souris, les cellules C2C12, sur nos substrats multi-échelles, nous avons observé leur auto-organisation en une “corde cellulaire” tridimensionnelle. Grâce à cette structure particulière, la différentiation a été favorisée par rapport aux méthodes classiques de la littérature. Ceci montre un impact réel de la géométrie du substrat sur le processus de différentiation. Nous proposons donc une méthode simple de myogénèse basée seulement sur l’auto-organisation cellulaire. Cette thèse peut avoir des applications dans l’ingénierie tissulaire<br>Group of cells in vivo need to move together in order to achieve physiological function. In particular, some cells are surrounded by extracellular matrix, a meshwork of proteins displaying sizes ranging from nanometers to hundreds of micrometers. In such environments, cells can move altogether directed by mesh orientation. This behaviour has been studied in vitro for simplified systems using guiding cues of different sizes. These studies show that the size of the cue controlled the cell collective motion. However, cell collective motion and the mechanisms involved in systems displaying a mix of different length scales cues are still unclear.In this thesis, we plated cells on substrates that have been textured at two length scales: subcellular microridges making an angle with a wider mesoscopic stripe. We show that the stripe’s width controls a transition at a critical width for the orientation angle of the cells between the two limiting cases. More precisely, middle angle in wider stripes is stabilized by a simple contact guidance effect independent of cell activity while collective cell migration display shear flows close to the edge of stripes. These observations fit a theoretical model we developed based on active matter framework. More interestingly, changing the microscale field orientation allowed us to measure the so-called flow-alignment parameter for the first time in such systems.Understanding these general mechanisms can be relevant in other several contexts in vivo, in particular during myogenesis. By seeding C2C12 mouse myoblasts cells on our previous multiscale system, we observed the self-organization of a 3D “cell cord” in the center of stripes. Due to their particular structures, differentiation was favored compared to classical patterns of the literature showing a real impact of geometrical conditions on cell differentiation processes. We then managed to provide a simple method of muscle differentiation based on cellular self-organization only. This thesis could have outcomes in the tissue engineering field

Full textAbstract:
The thesis consists of two volumes. Volume I comprises work in various areas of mathematical analysis, especially abstract harmonic analysis, differential equations and moment problems. Volume II comprises work primarily in harmonic analysis, especially work on the Fourier transform, invariant linear forms, and associated phenomena.
The ideas in this work have had a long period of gestation, although the fuller development and expression of them has occurred over a relatively short and intense period. The dominant ideas emerged in an endeavour to answer the following question: if f is a function in L2(IRn), how can the behaviour of its Fourier transform near the origin of IRn be described and characterized? The corresponding question for the circle group had been given a satisfactory answer by Gary Meisters and Wolfgang Schmidt in 1972, so the work also can be regarded as arising from an attempt to extend their result from the compact case of the circle group to the non-compact case of IRn. The answers presented to these and related questions have implications for other areas of analysis; the notable ones being the ranges of partial differential operators, and the behaviour of some of the singular integral operators of classical analysis.
