Johansson, Elias. "Pressure-based clog detection in SPE-columns." Thesis, Uppsala universitet, Institutionen för elektroteknik, 2021. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-446697.
Full textAbstract:
The concept of integrated sensors in the Biotage® Extrahera™ system to perform live-monitoring of pressure inside SPE-columns is investigated. A test-rig containing the components necessary to simulate the pressure-cycle in the system is constructed and a printed-circuit board assembly is designed and implemented into its 24-column format. Liquid samples with varying viscosity are then synthesized using water and glycerol, which are used in a simplified 2-step SPE-process during which the pressure inside the columns is logged. The results obtained showed that the concept is viable and methods for clog detection as well as state assessment are discussed. However, it was established that the solution needs further testing involving complete SPE-processes with real samples before any detailed algorithms can be presented. A pre-study is finally done regarding solutions for minimizing the design to allow for implementation into the system's more spatially restricted 96-column format.

Full textAbstract:
The purpose of this study was to enhance understanding of leisure experiences by applying an organizational approach to the sociology of leisure. This organizational approach, used mainly to study work and occupations, consists of a conceptual framework derived from social systems theory and structural functionalism. The sensitizing concepts used from this framework were recruitment, socialization, and identity.
In this study, I focused on the leisure group of clog dancers. My research questions, derived from this approach, include (1) How do clogging groups recruit their members? (2) How are people socialized into their role as cloggers and group members? (3) Do cloggers form a special identity because of this activity?
Twenty cloggers were interviewed for this study. All of the dancers were white, and all but one were female. Most of the dancers were married, and their ages ranged from 20 to 69 years. All of the dancers have clogged for at least four years, and half of the dancers have been clogging for 10 or more years. Their educational levels covered a wide spectrum, from less than high school to Master's degrees. Occupational status and income level also varied widely.
Through concept-driven interviews, the dancers indicated what they believed were important aspects of their leisure experiences. A majority of the dancers stated that they were recruited through social networks or by media influence. They experienced both formal and informal socialization in learning dance steps and how to perform as a team player in front of an audience. Finally, the dancers believed that they held a special identity because of their talents as a clogger. While each dancer derived different meanings from his/her identity as clogger, this identity appeared to be salient and psychologically central for all of the dancers interviewed.<br>Master of Science

Full textAbstract:
Monitoring the T1 relaxation of wetland clog matter has previously been identified as a gauge of its clogged state [1]. Magnetic resonance (MR) sensors explored in other work have typically been of a bore-whole configuration, which may not be ideal in a wetland environment where the sensitive volume of the sensor may become physically clogged and therefore inoperable. This work investigates two open-geometry sensor designs and a short study is presented to determine the suitability of the sensors for monitoring the clog state of
wetlands. It was shown that a bar magnet geometry has a higher stray field than that of the four magnet surface sensor also presented, leading to a prohibitively short T2 eff. This means that the T1 values collected are notably shorter and not useful for distinguishing between clog state for the single magnet sensor. By contrast the four magnet surface sensor has a longer T2 eff, making it more suitable for T1 measurements; where T1= 915 ± 212 ms for a very thinly clogged sample, and T1= 127 ± 27 ms for a heavily clogged sample. This offers a clearly resolvable difference in the T1 values allowing the clogging state to be easily determined and making this sensor the desirable choice for long-term embedding.

Full textAbstract:
The recent rise in interest of green technologies has led to significant adoption of the constructed wetland as a waste water treatment technique. This increased popularity has only been mired by the decline in operational lifetime of wetland units, leading to the need for more regular, time consuming, and expensive rejuvenation techniques to be performed than initially anticipated. To extend operational lifetimes and increase efficiency of wetland units, it is crucial to have an accurate method to determine the internal state of the wetland system. The most important parameter to measure within the reed bed is the clog state of the system, which is representative of the overall system health. In previous work, magnetic resonance (MR) measurements, parameters of T1 and T2 eff, have been demonstrated as extremely powerful tools to determine the internal clog state of a wetland [1, 2]. Measurements have been performed in a laboratory setting, using low field permanent magnet arrangements. This work presents an Earth’s Field Nuclear Magnetic Resonance (EFNMR) probe suitable for in situ measurements within constructed wetlands. We show T2eff and T1 measurements using the EFNMR probe. T1 values are shown to be sensitive to the change in the clog state with 1498 ms for the thickly clogged sample and 2728 ms for the thinly clogged sample. T2eff values are shown to be marginally more sensitive to clog state with 630 ms for a thickly clogged sample and 1212 ms for the thinly clogged sample. This gives distinguishable variation within both parameters suggesting that this probe is suitable for embedding into an operational constructed wetland. This work was conducted as part of an EU FP7 project to construct an Automated Reed Bed Installation, “ARBI”.

Ceci est une thèse en théorie des modèles appliquée à l'algèbre. Dans cette thèse nous étudions la théorie des corps pseudo-réels clos (corps PRC) et pseudo-p-adiquement clos (corps PpC) bornés d'un point de vue modèle-théorique. Les corps PRC et PpC sont des généralisations des corps pseudo-algébriquement clos (corps PAC), des corps réels clos, et des corps p-adiquement clos. Le résultat principal de cette thèse est une réponse positive à la conjecture de Chernikov, Kaplan et Simon : Si M est un corps PRC, alors M est borné si et seulement si Th(M) est NTP2. Dans le cas des corps PpC nous prouvons que si M est un corps PpC borné, alors Th(M) est NTP2. Nous généralisons également ce résultat pour obtenir que si M est un corps PRC (respectivement PpC) borné avec exactement n ordres (respectivement n valuations p-adiques), alors Th(M) est forte de fardeau n. Ceci permet également de calculer explicitement le fardeau des types et de décrire la déviation. D'autres résultats importants sont des résultats d'amalgamation de types et l'élimination des imaginaires pour les corps PRC bornés<br>This is a thesis in model theory applied to algebra. In this thesis we study the theory of bounded pseudo real closed fields (PRC fields) and pseudo p-adically closed fields (PpC fields) from a model theoretic point of view. The classes of bounded PRC and PpC fields are generalizations of those of pseudo-algebraically closed fields (PAC fields), real closed fields, and p-adically closed fields. The main result of the thesis is a positive answer to the conjecture by Chernikov, Kaplan and Simon: If M is a PRC-field, then Th(M) is NTP2 if and only if M is bounded. In the case of PpC fields, we prove that if M is a bounded PpC field, then Th(M) is NTP2. We also generalize this result to obtain that, if M is a bounded PRC or PpC field with exactly n orders or p-adic valuations respectively, then Th(M) is strong of burden n. This also allows us to explicitly compute the burden of types, and to describe forking. Other results of independent interest are some amalgamation results, and the elimination of imaginaries for bounded PRC fields. Keywords: Model theory, ordered fields, p-adic valuation, real closed fields, p-adically closed fields, PRC, PpC, NIP, NTP2, elimination of imaginaries

Full textAbstract:
Ce travail de recherche porte sur le problème de l'identification des sources de bruit en espace clos. La motivation principale était de proposer une technique capable de localiser et quantifier les sources de bruit à l'intérieur des véhicules industriels, d'une manière efficace en temps. Dans cette optique, la méthode pourrait être utilisée par les industriels à des fins de réduction de bruit, et donc construire des véhicules plus silencieux. Un modèle simplifié basé sur la formulation par sources équivalentes a été utilisé pour résoudre le problème. Nous montrerons que le problème est mal conditionné, dans le sens où il est très sensible face aux erreurs de mesure, et donc des techniques dites de régularisation sont nécessaires. Une étude détaillée de cette question, en particulier le réglage de ce qu'on appelle de paramètre de régularisation, a été important pour assurer la stabilité de la solution. En particulier, un critère de régularisation basé sur une approche bayésienne s'est montré très robuste pour ajuster le paramètre de régularisation de manière optimale. L'application cible concernant des environnements intérieurs relativement grands, nous a imposé des difficultés supplémentaires, à savoir: (a) le positionnement de l'antenne de capteurs à l'intérieur de l'espace; (b) le nombre d'inconnues (sources potentielles) beaucoup plus important que le nombre de positions de mesure. Une formulation par pondération itérative a ensuite été proposé pour surmonter les problèmes ci-dessus de manière à: (1) corriger pour le positionnement de l'antenne de capteurs dans l'habitacle ; (2) obtenir des résultats corrects en terme de quantification des sources identifiées. Par ailleurs, l'approche itérative nous a conduit à des résultats avec une meilleure résolution spatiale ainsi qu'une meilleure dynamique. Plusieurs études numériques ont été réalisées afin de valider la méthode ainsi que d'évaluer sa sensibilité face aux erreurs de modèle. En particulier, nous avons montré que l'approche est affectée par des conditions non-anéchoïques, dans le sens où les réflexions sont identifiées comme des vraies sources. Une technique de post-traitement qui permet de distinguer entre les chemins directs et réverbérants a été étudiée. La dernière partie de cette thèse porte sur des validations expérimentales et applications pratiques de la méthode. Une antenne sphérique constituée d'une sphère rigide et 31 microphones a été construite pour les tests expérimentaux. Plusieurs validations académiques ont été réalisées dans des environnements semi-anéchoïques, et nous ont illustré les avantages et limites de la méthode. Enfin, l'approche a été testé dans une application pratique, qui a consisté à identifier les sources de bruit ou faiblesses acoustiques à l'intérieur d'un bus.

Full textAbstract:
Background: Abnormal thrombus formation and occlusion of a vessel is one of the main events of cardiovascular disease. A main component of the thrombus is the protein fibrin, which is formed by proteolytic cleavage of its precursor fibrinogen by the serine protease thrombin. The cleavage of fibrinogen to fibrin releases fibrinopeptides from the E-region of the molecule which leads to the exposure of peptide sequences termed knobs A and B. The knobs A and B on one fibrin molecule are able to spontaneously interact to binding pockets (termed holes a and holes b) via hydrogen bonds forming half staggered protofibrils. These protofibrils laterally aggregate and form fibrin fibers, providing the clot its strength and stability. Recent molecular dynamic simulations have predicted that there are additional interactions involving amino acids gGlu323 with BLys58, gLys356 with BAsp61, and gAsp297 with BHis67, that surround the binding pocket and provide additional strength and stability to the 'classical' knob-hole contact. In this project I have termed these residues 'extended D-E knob-hole binding sites.' Aim: The aim of this project was to probe the importance of these extended knob-hole interactions in the process of fibrin polymerisation, clot structure and clot mechanics, using recombinant fibrinogen variants with mutations that abolish these electrostatic interactions. Methods: Four recombinant human fibrinogen variants and WT proteins were produced. The following variants with single point mutations in the g-chain of extended knob-hole binding region were produced: gD297N, gE323Q and gK356Q. A triple variant, gDEK (gD297N/gE323Q/gK356Q) with mutations in all residues involved was also produced. Each variant was tested for integrity by circular dichroism and SDS-PAGE. Turbidity and atomic force microscopy were used to study polymerisation kinetics, laser scanning confocal microscopy and scanning electron microscopy were used to study clot structure. Light scattering methods were used to study intrafibrillar protein structure, and clot mechanics was studied using an in-house micro-rheometer. Results: Longitudinal protofibril growth was disrupted for all variants except gK356Q at early stages of polymerisation, but normalised at later time points. Vmax was reduced for all variants. gDEK and gE323Q produced denser clots, whereas gD297N and gK356Q were similar to WT. All variant clots had significantly thinner fibers compared to WT. All variants were slower to lyse, with the exception of gD297N. Clot visco-elastic analysis showed that γDEK was more readily deformable (loss tangent, tanδ), at low frequencies but single mutant variants were unchanged at all frequencies compared to WT. Conclusion: I produced pure and intact recombinant human fibrinogens with mutations at the extended knob-hole binding sites. These data provide clear evidence for the role of extended D-E interactions in supporting the classical knob-hole binding during fibrin formation. Furthermore, the extended D-E interactions were shown to alter clot structure and clot mechanics. Additional studies with these variants in the presence of cells and other vascular components may further elucidate the importance of extended knob-hole interactions in haemostasis and thrombosis.

ADIJA, BINTY SAID. "Le clos et l'ouvert selon bergson." Poitiers, 1987. http://www.theses.fr/1987POIT5018.
Full textAbstract:
Parti de la philosophie de spencer, bergson decouvre la duree, c'est a-dire la mobilite et la continuite indivisee. Le changement est la rea lite essentielle de l'univers et de l'ame humaine. L'etude de la vie interieure va servir de fil conducteur aux problemes metaphysiques. La philosophie est "une psychologie qui se prolonge en metaphysique". Bergson nous invite a nous debarrasser des illusions produites par l'habitude, l'influence du langage; en un mot, il faut reagir contre le mecanisme d'une intelligence essentiellement utilitaire, car la philosophie ainsi comprise est un retour conscient aux donnees de l'experience interieure. De la distinction de la vraie duree et du temps homogene, il ressort que l'homme est libre et createur, mais sa volonte creatrice est constamment contrariee par l'instinct de conservation. C'est dans cette oscillation entre le clos et l'ouvert que va se faire le progres. La vision bergsonienne du monde est celle d'une marche vers la liberation. Il est possible de lever les obstacles imposees par la condition humaine en faisant appel aux etres privilegies tels que les heros et les saints. Ce depassement signifie que nous sommes convies a nous liberer de la necessite d'etre une espece pour etre pleinement homme, autrement dit, operer un bond hors de la nature pour etre totalement libre. La marche vers la liberation qui est une fusion avec le principe ne peut etre realisee qu'a travers la revolution la plus necessaire et la plus difficile, telle que la conquete du moi profond, le passage de la morale close a la morale ouverte, de la cite close a la cite ouverte<br>Starting from spencer's philosophy, bergson discovered the "duration", that is the mobility and the undivided continuity. The change is the essential reality of the universe and the human's soul. The study of the inside's life will help us to understand the metaphysical problems. The philosophy is " the psychology going toward metaphysics ". Bergson invite us to get rid of the illusions created by the habit and the language's influence. Summarily, we have to react against the mechanism of an essential and useful cleverness, because the philosophy understood by this way is a conscious return to the problem of our interior's experience. From the difference between the right "duration" and the homogeneous or the usual time, we can say that the human is free and creative; but his creative wish and capacity is always disturbed by the instinct of conservation. The progress will be effective within the oscillation between the "closed" philosophy and the "opened" philosophy. Bergson's vision of the world is a way leading to the liberation. It's possible to lift the obstacles imposed by the human's condition, by asking for a help from uncommon persons such as heros and saints. This overtaking means that we are invited to set ourselves completely free and to be really a human, not only one of species existing in the world. In another word, to jump out of the nature and to be completely free. The progress to the liberation which is a fusion with the principle, can be realized only through the most difficult and necessary revolution, such as the conquest of oneself deeply, the passage from the "closed" morals to the "opened" morals, from the "closed" to the "opened" city

Full textAbstract:
La production industrielle de microalgues a lieu principalement en conditions solaires et dans des bassins de culture ouverts. Dans l’optique d’étendre la gamme de souches cultivables et de réduire les coûts de production de la biomasse, de nombreux systèmes de culture clos (aussi appelés photobioréacteurs ou PBRs) se développent pour la production solaire de microalgues. Néanmoins, en raison de la dynamique du rayonnement solaire et de sa composition spectrale (présence de rayonnements infrarouges et ultraviolets), maximiser les performances d’un photobioréacteur solaire demeure complexe et tient en majeure partie à la gestion de deux paramètres : l’énergie lumineuse et la température de culture. Cette thèse présente l’ensemble des résultats obtenus en photobioréacteurs lors de l’étude de ces paramètres avec comme microalgue de référence, Chlorella vulgaris. La première partie a porté sur l’utilisation de l’énergie lumineuse par les algues au travers de la vitesse spécifique d’absorption de photons (RPA). Les résultats ont montré que l’efficacité de conversion des photons en biomasse était bien liée à la valeur moyenne de RPA dans le volume de PBR (aussi appelé MRPA), et que cette dernière était décroissante avec l’augmentation du MRPA. De plus, outre le MRPA, le profil de RPA peut aussi avoir un impact majeur sur la culture. En effet, il est possible d’inhiber toute croissance en imposant un profil de vitesse d’absorption de photons important dans l’intégralité du volume de culture. La deuxième partie de cette thèse a porté sur la gestion et l’optimisation des postes de consommation énergétique associés à la production solaire en PBR. Lors de cette partie, les coûts énergétiques liés à la production ont été associés aux performances théoriques de différents PBRs plans, afin de comparer ces systèmes entre eux (avec l’exemple d’une production de microalgue sur l’année à Nantes), et mesurer les efforts à réaliser pour envisager la production industrielle de microalgues dans le domaine de l’énergie<br>Industrial production of microalgae takes place outdoor in open ponds exposed to solar radiation. To increase biomass production and reduce production costs many closed systems have been developed such as photobioreactors (PBRs). Nevertheless, maximizing the performance of solar PBRs remains a challenge due to difficulties in managing radiant and thermal energy transfer in the PBR. This is mainly due to the dynamic behavior of solar irradiance as it evolves throughout the day and seasons. It is also because of the spectral composition of the solar radiation which consists of ultra-violet and infrared radiation. The latter cannot be utilized by the microalgae for photosynthesis and as a result is converted to heat. This thesis presents results obtained during the study of the effects of temperature and light on the microalgae production of the microalgae Chlorella vulgaris, chosen as a reference species. The first part of the thesis focused on the utilization of light energy by the microalgae with a specific attention paid to the parameter called the rate of photon absorption (RPA). Results show that the photon to biomass conversion efficiency is linked to the volume averaged value of RPA (also called MRPA for mean rate of photon absorption). Photon to biomass conversion efficiency decreased when the MRPA increased. Moreover, in addition to MRPA, the local value of RPA and its profile in the PBR volume can have a major impact on the culture behavior. Indeed, it is possible to inhibit cell growth by having a large RPA in the PBR leading to excessive absorption of photons throughout the PBR. The second part of the thesis focused on management and optimization of energy demanding units associated to the culture of solar PBRs. During this part, energetic costs linked to the biomass production where associated to the theoretical performances of different planar systems in order to compare them (with the example of an annual production in Nantes (France)), and determine the efforts necessary to implement microalgae on industrial scale in the field of energy

This master's thesis in creative work is divided in two parts: a compilation of novels and a critical study. The creative work is entitled "Les lits clos". It is a compilation of nine novels imprint with black humor. This creative work tends to demonstrate that daily routine is a source of black humor and that reality is nothing but the perception that everyone makes of it.<br>"Les lits clos" will be preceded by a critical study which intends to explain what is black humor by following Andre Breton, founder of that term. First of all we will discuss of Jacques Vache who, in his correspondence with Andre Breton, was interested to what he called "Umour". Then we will see how Breton, using Freud's theory, has refined objective humor created by Hegel. Black humor is at first a search for freedom, moreover the desire to overcome death. Black humor is nourished by the imagination to recover the origin of image. The black humorist lies between the subjective and the objective and tends to stay in balance within each other.

Pan, Xiaoxi. "Fibrin clot structure alterations after particulate matter exposure." Thesis, University of Leeds, 2016. http://etheses.whiterose.ac.uk/14310/.
Full textAbstract:
Particulate matter (PM) as an important part of ambient air pollution has been associated with increased risks of cardiovascular diseases. Fibrin clot structure alteration is an emerging risk factor of many cardiovascular diseases, especially thrombosis. Therefore, the aim of this study was to investigate whether and how air particulate matter affects fibrin clot structure and endothelial cell behaviour. Turbidity assay, turbidity lysis assay and laser scanning confocal microscopy were used to analyse clots formed from normal pooled plasma or purified fibrinogen, in the presence of varying concentrations of PM. It was found that clots formed from plasma with higher concentrations of particles led to prolonged lysis time compared to control. No differences were seen for clots formed from fibrinogen. In a study of clots formed from plasma samples collected as part of a previous study on the effects of air pollution on deep vein thrombosis (DVT), alterations were observed in clots formed from plasma of DVT patients exposed to high levels of PM compared to those exposed to low levels, but the same differences were not observed in clots formed from plasma of control subjects. To investigate the potential role of venous endothelial cells in moderating clot structure following exposure to PM, human umbilical vein endothelial cells (HUVEC) were treated with PM for 24 hours and clots subsequently formed on the cells. Clots formed from plasma on the treated cells were altered compared to controls. RT-PCR and ELISA results showed increased gene expression of tissue factor (TF), protein expression of von Willebrand Factor (VWF) and plasminogen activation inhibitor-1 (PAI-1) and decreased thrombomodulin mRNA expression which were consistent with changes observed in clot structure. Engineered SiO2 nanoparticles caused denser clot structure in clots formed from normal pooled plasma. The gene expression of thrombomodulin was inhibited by SiO2 nanoparticles, but there were no significant difference in the TF mRNA expression between control and treated cells. Silica NPs caused increased concentrations of VWF, but not PAI-1 produced by endothelial cells. The results presented here show that PM can induce changes to clot structure and function, and that changes in gene expression induced in endothelial cells may be a mechanism by which a prothrombotic state is induced in response to PM exposure. Furthermore, some, but not all, similar changes were observed in clots and cells exposed to SiO2 nanoparticles, raising the possibility that such engineered nanoparticles may also have the potential to contribute to cardiovascular toxicity.

Ce mémoire a pour objectif d’étudier si les trois protagonistes dans la pièce de théâtre Huisclos, écrite par Jean-Paul Sartre en 1944, sont sous l’emprise d’un jeu relationnel, notammentle Triangle Dramatique de Karpman. Un Triangle Dramatique se compose de trois rôles, uneVictime, un Persécuteur et un Sauveur. L’essence du Triangle Dramatique est de déstabiliserl’autre et de répéter des scénarios de vie souvent dysfonctionnels mis en place tôt dans la vie.<br>The objective of this research is to study whether the three protagonists in the theatre play NoExit (Huis clos), written by Jean Paul Sartre in 1944, are influenced by a relationship game, in this case Karpman’s Drama Triangle. The Drama Triangle consists of three roles, a Victim, aPersecutor, and a Rescuer. The essence of the Drama Triangle is to destabilise others, accordingto a life script that is often dysfunctional and set early in life.

Full textAbstract:
Plasma clot structure/function is a major determinant in cardiovascular disease risk and severity. Plasma proteins are incorporated into plasma clots via binding and factor XIII-dependent cross-linking, with complement C3 and factor H previously identified as plasma clot components using proteomics. The aim of this current project was to validate the role of C3 and factor H in fibrin structure and function and to establish a proteomics method for the identification of novel factor XIII substrates. C3 did not affect fibrin structure; however C3 induced a concentration-dependent prolongation of fibrinolysis. C3 was cross-linked to fibrin within purified and plasma clots and bound to plasma clot components. C3 was a substrate for plasmin, with cleavage occurring in the presence and absence of fibrin. C3 also influenced angiostatin production and t-PA and plasminogen interactions within fibrin clots to prevent plasminogen cleavage and plasmin generation. All of these interactions were found to influence fibrinolysis. Whereas factor H was confirmed to be a plasma clot component, was associated with inflammation and fibrin structure and function but was not associated with complement activation in individuals at risk of cardiovascular disease. Further in vitro analyses found that factor H did not affect fibrin structure or fibrinolysis. Factor H was not cross-linked to fibrin in purified and plasma clots, but did form homodimers in the presence and absence of fibrin and factor H was a substrate for thrombin and plasmin, with cleavage occurring within fibrin clots. The proteomic techniques were established for the identification of factor XIII substrates however no novel proteins were identified using these methods, suggesting the sensitivity of the technique may be insufficient to detect novel proteins. This study has added to the growing body of evidence which suggests complement and coagulation pathways interact for the purposes of preventing blood loss and pathogen invasion.

Full textAbstract:
Ce travail consiste en l'analyse narrative de films "a lieux clos", dans laquelle chaque film est concu comme objet et comme outil. En amont des analyses, une premiere partie situe la reflexion dans le paysage de la narratologie et definit un cadre terminologique precis. Le premier chapitre propose une mise en perspective des textes fondateurs de la narratologie litteraire (barthes, greimas, genette) ainsi qu'une lecture critique des conceptions du recit filmique. Le second chapitre redefinit l'image mouvante audiovisuelle comme une entite distincte du plan, construite dans l'espace de la reception, definie par une tension entre duree et mouvement. Le troisieme chapitre se presente comme un parcours a travers les differents types d'espaces dans le film. La notion de lieu, situee a la croisee de l'iconicite, de la figurativite et de l'abstraction, occupe une place centrale. La partie analytique est consacree a sept films classiques hollywoodiens : rebecca (hitchcock), experiment perilous (tourneur), gaslight (cukor), the spiral staircase (siodmak), dragonwyck (mankiewicz), the secret beyond the door (lang), the red house (daves) ; un film moderne : the shining (kubrick) ; enfin, unfilm dans lequel la question de la cloture se trouve deplacee du lieu diegetique vers le recit : the french lieutenant's woman (reisz). Le lieu est envisage tout d'abord comme le lieu de memoire du passe. Il est ensuite aborde sous l'angle de la centralite et comme structure geometrique. Cette structure est la manifestation spatiale des relations entre les personnages. Dans le film de reisz, la frontiere ne separe pas un dedans et un dehors diegetiques, mais deux strates narratives. Cette frontiere tend, en certains endroits, a s'annuler, grace, entre autres, a des elements touchant aux lieux et a leur organisation. Le lieu et le recit ont en commun de s'ancrer dans les images, de courir de l'une a l'autre et, ce faisant, de s'abstraire de l'image pour s'echouer dans la memoire.

Full textAbstract:
Two methods of generating self-similar Internet traffic are reported in this document. The first method uses Heavy-tailed Pareto distribution and generates fixed length packets, while the second method focuses on Fractional Gaussian Noise as means of generating variable-length packets. Various testing have been performed on the traffic to corroborate its self-similarity and measure relevant statistics.
Using the self-similar traffic environment, the performance of a sectored three-stage packet switch architecture is evaluated which benefits from both photonic and electronic technologies and provides variable bandwidth between sector pairs by changing the configuration of the photonic centre stage according to arriving traffic. This architecture reduces complexity, at the price of a modest spatial speed-up, which is easy to provide with photonic technology.
As an alternative to reconfiguration, a novel load-balancing Clos-like architecture and method without miss-sequencing is proposed. The architecture involves no central schedulers and is implemented by distributing cross-point queues over all elements of the switch and deploying pollers to select the queues to be served. This method is simple and practical and shows delay performance that approaches that of an ideal output queued switch.

Full textAbstract:
Partant d'un materiel destine au monde juridique, nous avons travaille l'aspect psychologique et psychopathologique de la problematique incestueuse a travers l'exploration de cinquante deux dossiers juges aupres des tribunaux de lyon. La specificite de ce terrain de recherche nous a permis d'aborder cette question dans une double orientation : sociale et clinique. Le point d'articulation entre ces deux axes se situe au niveau de la loi. En effet, cette derniere fonde le groupe social et fonctionne comme organisatrice de la psyche. Lorsqu'un inceste se realise, il exprime un defaut de la loi tant au niveau familial qu'individuel. La fonction organisatrice de l'interdit de l'inceste vise a distinguer les places et roles de chacun (difference des sexes et des generation), et donc a introduire les notions de differenciation et de separation. Au sein du systeme incestueux, chacun lutte contre toute forme de separation eveillant de fortes angoisses d'abandon, voire de mort. L'origine d'une impossible tolerance a la separation se situe dans un vecu archaique de detresse psychique. La mere se serait presentee prematurement a l'enfant comme trop absente, trop frustrante et donc trop mortifere. La quete de l'abuseur et de la victime se font miroir dans la mesure ou tous deux cherchent a panser leurs carences en pansant simultanement celles de l'autre. La relation incestueuse renvoit a l'illusion d'une rencontre avec un incestueux refletera la nocivite du lien originaire<br>Using a material meant in priority for the legal world, we investigated the psychological and psychopathological aspect of the incestuous issue through the exploration of fifty-two dicuments judged by the lyon's courts of justice. The specificity of this research field allowes us to tackle this question in a twofold orientation : social and clinical. The way of structuring these two domains is placed at the level of the law. Indeed, this latter builds the social group and functions as organizer of the psyche. When an incest happens, it expresses a defect of the law, as much at the family level as at the individual level. The organizer function of the incest forbidden leads to distinguish situations and roles of everyone (sex and generation differences) and therefore to introduce the notion of differentiation and separation. Within the incestuous system, each one fights against all forms of separation arousing strong fears of neglect and even of dying. The origin of an impossible tolerance to the separation is placed in an archaic real-life experience of psychic distress. The mother would appear prematurely to the child as too far away and too frustrating. The rapist and the victim'search is mirrored insofar as both of them look for dressing their own deficiencies by simultaneously dressing those of the other. The incestuous relation refers to the illusion of a meeting with an idealized maternal object, never found. However, finally, the harmfulness of the incestuous the reproduces the harmfulness of the native tie

Full textAbstract:
L'occupation quasi constante des environnements intérieurs (en moyenne 90% du temps), expose en permanence les occupants à une large variété de microorganismes présents dans l'air de ces espaces. En raison de difficultés technologiques liées à la collecte et à l'analyse, ce domaine scientifique reste pourtant quasiment vierge et ce, malgré les retombées possibles dans le domaine de la santé. Le manque est particulièrement marqué, en ce qui concerne l'exposition des individus aux aérosols microbiens et plus globalement la gestion sanitaire de la qualité de l'air des espaces clos. Cette étude a pour objectif la caractérisation de la diversité microbienne de l'air de différents espaces clos collectifs par une approche qualitative et quantitative. L'ensemble de l'étude a porté sur des environnements sensibles d'un point de vue des occupants (Hôpital), de la densité de fréquentation (Le Musée du Louvre) ou d'un temps d'exposition prolongé (Bureau).L'originalité de cette thèse a résidé dans l'association d'une stratégie d'échantillonnage représentative des environnements étudiés et d'outils analytiques pertinents permettant d'étudier la microflore de l'air indépendamment de la cultivabilité des micro-organismes. Pour la première fois, un séquençage haut débit (pyroséquençage 454) a été appliqué à des échantillons d'air intérieur permettant d'accéder à une diversité microbienne rare comme le sont les espèces pathogènes. Les résultats montrent une diversité microbienne plus riche que celle habituellement observée par des méthodes culturales. Plusieurs micro-organismes impliqués dans des problématiques sanitaires ont été retrouvés (Borrelia spp., Burkholderia spp., Legionella spp., Neisseria spp. et Mycobacterium spp.). Les résultats mettent en évidence une stabilité à la fois spatiale et temporelle pour les bactéries retrouvées dans l'air intérieur. Cette stabilité est à la fois qualitative (structure des communautés microbiennes) et quantitative (abondance des microorganismes). La forte présence de séquences d'origine humaine permet de considérer l'Homme comme le principal élément orientant la microflore bactérienne de l'air intérieur. Des « cores species » signant l'air intérieur anthropisé ont pu être identifiées<br>The constant occupation of indoor environments (average 90% of the time), constantly confront the occupants to a wide variety of microorganisms from the air of these spaces. Due to technological difficulties related to the collection and the analysis of airborne microorganisms, this field of study remains scanty, despite the potential health impact. The lack is particularly pronounced in terms of understanding of the risks of contamination of people by bioaerosols and overall health management of air quality of confined spaces.This study aims to characterize dynamics of the microbial diversity of different indoor environments. The entire study involved representative environments (hospital, office and museum).The originality of this thesis is the combination of a representative sampling strategy on environments studied and of analytical tools relevant to study the microflora of the indoor air regardless of the culturability of microorganisms.. For the first time, a high throughput sequencing (454 pyrosequencing) was applied to samples of indoor air in order to assess microbial diversity and pathogenic species..Several microorganisms implicated in health problems were found (Borrelia spp., Burkholderia spp. ,Legionella spp., Neisseria spp. and Mycobacterium spp.).The results give a different and more varied qualitative picture than that usually observed by cultural methods. The results show a stability of both spatial and temporal microflora of indoor air. This stability is both qualitative (microbial community structure) and quantitative (abundance of microorganisms). Man can be considered as the main factor driving the indoor air microflora due to the strong presence of sequences of human origin.'Cores species' signing the antropogenic indoor air were identified

The purpose of this research is to analyze how a lesser amount of water from a 1.6 gallon per flush water closet affects drainage in a four inch diameter pipe at 1/4" slope. Low flow water closet manufacturers ensure that waste clears the bowl, but there is no significant research following the flushed water further down the pipe line. This research utilizes a 1.6 gallon per flush floor-mounted water closet connected to 30 feet of sloped four inch PVC Drain Waste Vent piping.
Data presented from 25 flush trials indicates that further research needs to be conducted at a smaller pipe diameter. Four-inch piping is too large, causing the 1.6 gallons of water to quickly lose the required force over the course of 30 feet, resulting in pipe line clogs. An average of four additional water-only flushes are necessary to completely clear the test media and toilet paper from the pipe.
This research references previously published research and focuses on test results presented by the Plumbing Efficiency Research Coalition. Two case studies of city wide replacements of old water closets are presented to discuss the viability of city wide mandates in relation to water conservation.

A orientação a objetos, enquanto modelo de organização de linguagens de programação,vem tomando espaço e importância cada vez maiores a partir do início da década de 80. Entre as linguagens de programação orientadas a objetos existentes, destacam-se por seu poder de expressão as extensões orientadas a objetos da linguagem Lisp. Lisp é uma importante linguagem de programação, de características funcionais, cujas origens remontam aos primórdios da Computação. Um passo à frente nesse panorama se coloca o Common Lisp Object System(eLOS). Mais que apenas uma extensão de Lisp orientada a objetos, o CLOS se propõe a fundir os paradigma funcional à orientação a objetos em uma linguagem rica, poderosa e eficientemente implementável. Neste trabalho, apresentamos uma implementação didática, portável e extensível do CLOS, apontando as soluções dadas aos principais problemas que foram deixados em aberto na sua especificação. Além disso, propomos um framework para descrição e análise de linguagens de programação orientadas a objetos,'; que servirá. de arcabouço para uma análise comparativa das principais extensões de Lisp orientadas a objetos (Flavors, Loops, ObjVlisp, CommonObjects, CLOS) e de uma descrição de duas das mais importantes linguagens orientadas a objetos: Smalltalk e C++. Por fim, propomos uma extensão do eLOS para solução distribuída de problemas baseada na arquitetura do Quadro-Negro (Blackboard), o DCK (a Distributed CLOS Kernel). Essa proposta utiliza um kernel para solução distribuída de problemas que opera sob Unix, chamado DPSK.

Full textAbstract:
Bien des critiques définissent l'univers de Michel Tournier comme un univers sans femme. Cependant, nous arrivons à en trouver certains avatars. Les personnages féminins sont représentés, chez Tournier, de façon générale, par un espace profond sans sortie. Nous pouvons classer le personnage féminin en deux catégories : " femme - espace clos " et " femme - espace clos-ouvert ". Le portrait de femme et la femme photographe liés à l'image profonde seront aussi traités comme modification de la " femme - espace clos ". Le refus de la femme de la part des héros tourniériens vient, en effet, de la peur de l'espace féminin dont le caractère principal est la profondeur. Car cet espace féminin qui évoque la nostalgie de la paix douce dans le ventre maternel et qui séduit les hommes par sa profondeur et son intimité met en péril la vie du protagoniste masculin. Les protagonistes masculins comprennent qu'ils doivent en sortir pour survivre et enfin pour renaître en un autre homme. Ainsi le personnage féminin de l'espace clos se révèle, au demeurant, comme une épreuve initiatique qui prépare la naissance d'un héros en quête de l'éternité et de l'immortalité. Les héros masculins dans la trilogie de Tournier s'attachent donc à regagner l'androgynéité perdue de l'homme à travers les efforts visant à retrouver la surface et à couvrir cet espace. Si Robinson et Tiffauges y parviennent par la voie de la phorie, Paul y arrive par la perte de son frère jumeau et la mutilation de son corps, qui lui permet de retrouver l'unité gémellaire en soi-même et de devenir le frère des hommes. Le lecteur, par l'acte de lire et de réécrire, peut non seulement achever l'œuvre, mais aussi participer au chemin menant à la sublimation ; sublimation à laquelle les héros parviennent à la faveur de la maternité regagnée, chez l'homme, et de la fraternité universelle avec tout le monde et toutes les choses<br>Many critics define the universe of Michel Tournier as a womanless one. Nevertheless, it must be said that certain avatars can be found in this universe. In Tournier's work, women are generally represented by a deep space with no exit. It is possible to classify two types of female characters: "woman - enclosed space" and "woman - open-closed space". Portraits of women and women photographer linked to the deep image will also be considered as variations on the "woman - enclosed space". The refusal of women by Tournier's heroes is due to the fear of feminine spaces, principally characterized by depth. It seems that this feminine space, conjuring up the nostalgia of peace and gentleness in the mother's womb, and seducing men by depth and intimacy, presents a threat to life of Tournier's male characters. These male protagonists recognize that they must escape from such a space in order to survive, and ultimately, to be reborn as new men. Thus the female character, and the enclosed space she represents, prouve to be an initiatic rite which prepares the birth of a hero in search of eternity and immortality. The male heroes in Tournier's trilogy therefore actively seek to return to the primordial androgynous state that allows them to return to the surface and to cover this space. While Robinson and Tiffauges achieve this end by phorie, Paul reaches this goal through the loss of his twin and the mutilation of his body which permit him to find twinness within himself and ultimately, to discover the brotherhood of man. Through the act of reading and rewriting, the reader can not only complete the work but also follow Tournier's heroes on their search for sublimation as they open up the way of male maternity and universal fraternity

Depuis 1985, le sida a provoqué de multiples tensions entre espace privé et l'espace public, qui ne sont pas entièrement résorbées malgré les savoirs accumulés sur l'épidémie. La socialisation de ces savoirs a souvent été réduite à des dispositifs préventifs relevant de procédures didactiques et injonctives. Le désarroi des autorités sanitaires a débouché sur une politique de prévention à grande échelle, porteuse de contradictions car menée principalement en direction d'une catégorie préconstruite et captive : les jeunes. Quant à la population séropositive, la question de son insertion professionnelle demeure entière, en dépit des progrès thérapeutiques enregistrés depuis 1996. En majorité, les personnes atteintes gardent encore secret sur leur état sérologique sur le lieu de travail : dans la confrontation des sphères privée et publique, la discrétion peut être nécessaire à la sauvegarde de l'intimité comme du lien social.

Full textAbstract:
mestrado em Engenharia Química<br>Este trabalho constou num estudo do modelo de cálculo de eficiência de reatores de 𝐶𝑙𝑂2, denominado processo Mathieson, com o intuito de melhorar o seu desempenho. Para tal pretendia-se melhorar alguns parâmetros suscetíveis de modificação do processo.
O processo Mathieson baseia-se na redução de clorato de sódio com dióxido de enxofre em meio ácido. A produção de dióxido de cloro a partir do clorato de sódio utiliza uma solução concentrada de ácido sulfúrico. Este processo é constituído por uma sequência de três linhas (𝑅1, 𝑅2 e 𝑅3), ligados paralelamente, em que cada sequência é constituída por um reator primário, secundário e uma torre de lavagem.
Para isso, numa fase preliminar realizou-se um balanço material com o intuito de determinar a proporção de 𝑆𝑂2/ar que é enviada para os reatores secundários, sabendo que esta não é contabilizada. O rácio de produção do dióxido de cloro, relativamente aos consumos de reagentes (clorato de sódio, ácido sulfúrico e enxofre) foi, também, determinado. Estudou-se o efeito de um aumento a temperatura do reator primário e secundário da linha 𝑅3. Com este aumento no reator primário da sequência 𝑅3 constatou-se a diminuição do caudal volumétrico de ácido sulfúrico de 19,93%, uma diminuição na concentração de ácido sulfúrico residual de 0,705% no reator primário, bem como um decréscimo de 26,46% na concentração de clorato de sódio residual no stripper. Com este aumento de temperatura notou-se aumento no rácio da produção diária de dióxido de cloro de 3,87%.
Posteriormente, e tendo em conta os resultados positivos verificados com o aumento da temperatura do reator primário e secundário da sequência 𝑅3, estudou-se o efeito de um aumento da concentração de 𝑆𝑂2/ar nos reatores primários da sequência 𝑅1 e 𝑅2 de 11,25 𝑚𝑜𝑙 𝑆𝑂2/𝑚𝑜𝑙 𝑎𝑟 para 11,94 𝑚𝑜𝑙 𝑆𝑂2/𝑚𝑜𝑙 𝑎𝑟.
Os resultados obtidos mostram um aumento de 11,85% nos reatores primários da sequência 𝑅1 e 𝑅2.
Por fim, realizou-se uma breve análise económica em que se avaliou a eficiência económica da produção de dióxido de cloro. Verificou-se que, com o aumento de temperatura nos reatores primários e secundários, houve uma redução, por tonelada, no custo de produção de dióxido de cloro, de 45,26€. Concluiu-se que o aumento da temperatura dos reatores primários e secundários, em conjunto com o aumento da concentração de 𝑆𝑂2/ar, favorecem a economia de produção de dióxido de cloro.<br>This work consisted on a study of the model reactor efficiency calculation of 𝐶𝑙𝑂2, designated Mathieson process, in order to improve his performance. It was intending to improve some parameters susceptible to process modification.
The Mathieson process is based on reduction of sodium chlorate with sulphur dioxide in acidic medium. The production of chlorine dioxide from sodium chlorate using a concentrated sulfuric acid solution. This process consists in a sequence of three lines (𝑅1, 𝑅2 and 𝑅3) parallel linked, wherein each sequence is constituted by a primary reactor, secondary reactor and stripper.
In a preliminary phase it was performed a material balance in order to determine the proportion of 𝑆𝑂2/air that is sent to the secondary reactor, knowing that this is not accounted for. The ratio of chlorine dioxide production according to the consumptions of reagents (sodium chlorate, sulfuric acid and sulphur) was also determinated. The effect of an increase in temperature of the primary and secondary reactor 𝑅3 sequence was studied. With this increase in the primary reactor 𝑅3 sequence, it was verified a reduction of the volumetric flow rate of sulfuric acid of 19,93%, a decrease in the sulfuric acid residual concentration of 0,705% and a decrease of 26,46% in the sodium chlorate residual concentration in the stripper. With this increase in temperature showed a growth in chlorine dioxide production ratio of 3,87%. Subsequently, taking into account the positive results observed with increasing of the temperature of the primary and secondary reactor 𝑅3 sequence, it was studied a rising of the 𝑆𝑂2/air concentration on the reactors 𝑅1 and 𝑅2 sequence with the difference of 11,25 𝑚𝑜𝑙 𝑆𝑂2/𝑚𝑜𝑙 𝑎𝑖𝑟 to 11,94 𝑚𝑜𝑙 𝑆𝑂2/𝑚𝑜𝑙 𝑎𝑖𝑟. The results displayed an increase of 11,85% in primary reactors 𝑅1 and 𝑅2 sequence.
Finally, was performed an economic analysis which evaluated the economic efficiency of chlorine dioxide production. It was found that, with increasing temperature in the primary and secondary reactors, a reduction per ton, of the cost of chlorine dioxide production, of 45,26€.
The conclusion was that the increase of temperature of the primary and secondary reactors with the increase of 𝑆𝑂2/air concentration benefits the chlorine dioxide production economy.

Full textAbstract:
En raison de sa nature hautement inflammable, l’hydrogène constitue un risque technologique important et son utilisation nécessite un très haut niveau de sûreté. Le travail de thèse présenté dans ce mémoire a été réalisé en collaboration avec EDF et s’inscrit dans le cadre des études de sécurité liées à la libération d’hydrogène dans un des locaux de l’îlot nucléaire. Le dégagement d’une fuite peut, en effet, entraîner la formation d’une atmosphère inflammable, qui peut exploser et provoquer des graves dégâts.Cette étude vise ainsi à apporter une meilleure compréhension des phénomènes de dispersion et de déflagration à l’issue d’une fuite d’hydrogène. Les résultats expérimentaux obtenus à échelle de laboratoire sont comparés aux simulations numériques obtenues via le logiciel FLACS. Un plan détaillé a donc été élaboré, en divisant le mémoire en deux parties : dispersion et déflagration. Pour chaque partie, un point bibliographique est proposé, ainsi qu’une description des dispositifs expérimentaux utilisés. Une partie expérimentale et numérique est présentée pour chacun des deux phénomènes. Les travaux réalisés ici ont donc permis d’obtenir une analyse réelle et complète du phénomène de rejet d’hydrogène en milieu fermé et obstrué et d’explosion de mélange hétérogène hydrogène-air à petite et grande échelle. Les cas les plus pénalisants en termes de concentration maximale et gradient de concentration ont été identifiés à travers une étude paramétrique sur l’influence du débit et de la position du rejet sur la dispersion. Les conséquences lors de la déflagration de ces mélanges hydrogène-air ont ensuite été étudiées à travers l’analyse de l’onde de pression et de la propagation de la flamme<br>The highly combustible nature of hydrogen poses a great hazard and its use imposes an accurate analysis of risk characterization and consequences to protect the installation and to reduce the potential risk. This thesis has been done in collaboration with EDF and it is included in the context of the explosion risks of an air hydrogen mixture in a room of the nuclear facility where there is a risk of accidental release. Indeed, the hydrogen can disperse quickly and burn easily in the presence of an ignition source causing heavy damage. The goal of this study is to provide a better understanding of the phenomena of dispersion and deflagration after an accidental release of hydrogen. Experimental results obtained at small scale are compared with numerical simulations obtained using FLACS code. A detailed plan has been drawn up, dividing the thesis into two parts: dispersal and deflagration. For each part, a bibliographic point is proposed, as well as a description of the experimental devices used. An experimental and numerical part is presented for each of the two phenomena. The studies carried out here have thus enabled us to obtain a real and complete analysis of the phenomenon of closed and clogged hydrogen discharge and small-scale and large-scale heterogeneous hydrogen-air mixture explosion. The most penalizing cases in terms of maximum concentration and concentration gradient were identified through a parametric study on the influence of the flow rate and the position of the rejection on the dispersion. The consequences during the explosion of these hydrogen-air mixtures were then studied through the analysis of the pressure wave and the propagation of the flame

PLASMIN-MEDIATED CONVERSION OF FXa INTO A CLOT-DISSOLVING COFACTOR.
Factor Xa (FXa) is an essential blood clotting enzyme. A previously identified FXa derivative, Xa33/13, is generated by two distinct cleavages by the clot-dissolving (fibrinolytic) enzyme, plasmin. FXa is first converted to FXaβ by excision of a small C-terminal peptide and then proteolyzed at Lys330 in the autolysis loop to yield Xa33/13, which cannot participate in clotting. Instead, these cleavages confer novel fibrinolytic function to Xa33/13 as a tissue plasminogen activator (tPA) cofactor, thereby accelerating plasmin generation. To understand the importance of each cleavage and the role of individual residues in this functional conversion of FXa, five mutants were generated by mutation of basic residues to glutamine: Lys330 and four residues in the β-peptide region. Mutation at Lys330 prevented autolysis loop cleavage, and this mutant dissolved purified fibrin clots faster than plasma-derived FXa derivatives. Additionally, no basic residue within the β-peptide was uniquely targeted by plasmin and no single-point mutation in this region prevented subsequent autolysis loop cleavage.
FX-DEFICIENT PATIENT.
Factor X (FX) can be activated by two separate protein complexes, known as the initiating (extrinsic) and amplifying (intrinsic) tenases, which are assembled during coagulation. I describe a FX-deficient patient with a novel compound heterozygous mutation associated with differential clotting pathway function. Quantification of plasma FX antigen revealed 15 % of normal, which was consistent with extrinsic pathway activity. Intrinsic pathway activity was reduced to 5 % of normal, suggesting an activatable specific activity 3-fold lower than expected for this branch of the clotting pathway. DNA sequence analysis identified two heterozygous mutations: (1) a previously reported mutation that disrupts the splice site between exons I and II; (2) a novel mutation resulting in an Arg386Cys substitution in the protease domain. I propose that alternate disulfide bond formation and protein folding may reduce circulating FX antigen levels. Additionally, Arg386 may be involved in substrate recognition by the intrinsic tenase complex, providing a possible explanation for the differential effect on the two branches of the coagulation cascade. Recombinant FX mutant studies confirmed our findings in patient plasma and provided further support for these hypotheses.
