Abstract:

Devant le déclenchement des hostilités entre le FPR et les FAR en 1990, l'organisation des Nations Unies à la demande des deux parties, choisit de s'impliquer directement. Mais l'intervention de l'ONU et l'envoi des casques bleus qui survient après la signature des Accords d'Arusha de 1993 afin d'accompagner lesdits accords, n'arrête cependant pas la montée des violences et de l'extrémisme Hutu. Les différentes résolutions du Conseil de sécurité, loin d'accorder plus de pouvoir aux casques bleus, créent au contraire une situation d'immobilisme général, favorisant au printemps 1994 la reprise des combats et le génocide des Tutsi et des Hutu modérés. Le drame humanitaire que connaît le Rwanda pendant et après les affrontements et les massacres, nous interpelle sur le véritable rôle des Nations Unies dans la gestion de ce conflit, et plus généralement dans le monde de l'après guerre froide<br>Before the outbreak of hostilities between the RPF and the FAR in 1990, the United Nations became directly involved after both parties asked it to arbitrate the conflict. But the intervention of the UN and the deployment of peacekeepers that came after the agreement of Arusha in 1993 in order to accompany the agreements did not stop violence and the rise of Hutu extremism yet. The various resolutions of the UN Security Council, far from granting more power to peacekeepers, instead created a situation of stagnation favoring the resumption of fights in 1994 and the genocide of Tutsi and moderate Hutu. The humanitarian tragedy facing Rwanda during and after the clashes and massacres appeals us on the proper role of the United Nations in the management of this conflict in particular, and in the post-cold war world in general

Abstract:

Magíster en Gestión y Dirección de Empresas<br>El presente trabajo tiene como objetivo el desarrollar una estrategia de crecimiento para una consultora de servicios de ingeniería en gestión de mantenimiento, FPR Ingenieros Consultores, cuyo actual nicho es la industria minera. El objetivo principal es que dicha estrategia le permita obtener rendimientos sobre el promedio de la industria en forma sustentable, teniendo claridad sobre las acciones y medidas pertinentes que harán cumplir los objetivos planeados. Chile es un país rico en recursos mineros, lo que lo hace un foco atractivo para capitales extranjeros. Lo anterior trae consigo una serie de desarrollos económicos adyacentes a esta industria, lo cual ha generado polos de negocios regionales centralizados, atrayendo inversión extranjera, lo que hace al país cada vez más competitivo. Según estadísticas de Sonami, emitidas en la publicación Perspectivas de la minería latinoamericana y chilena nuestro país proyecta una inversión de US$ 4.000 millones para el período 2010 2017 en servicios de ingeniería y consultoría para la industria de la minería. Para cumplir con el objetivo, se utilizó la metodología de un proceso formal de administración estratégica. La metodología considera el análisis del entorno e industria, estructura interna de la empresa, formulación y definición de misión y visión, análisis y evaluación de estrategias, implementación y control de proyectos, todo bajo un análisis económico de valor actual neto (VAN), tasa interna de retorno (TIR) y periodo de recuperación de la inversión (PRI). Los resultados esperados se encuentran descritos por las variables analizadas dentro de un plan de crecimiento, destacando el aumento de la facturación, del número de clientes y su fidelización, y el posicionamiento en lugares estratégicos en relación a la industria minera. Luego del análisis, creación e implementación de las soluciones propuestas, se generó un escenario con un crecimiento sostenido en la facturación de un 40% anual, y un incremento de 30% en el número de clientes para el mismo período. Al realizar la evaluación se obtiene un VAN de $ 690 millones, una TIR de 154% y un PRI de 0.13 años, resultados muy auspiciosos para la decisión de implementación. Se puede concluir que existe un enorme potencial en el desarrollo de negocios, esencialmente por el bajo ítem de inversiones versus el alto grado de retornos, cuyo principal eje radica en la correcta estrategia comercial utilizada para penetrar en los mercados de la industria minera, manejo y conocimiento de la industria de consultoría, y expertise en los procesos.

Abstract:

Les cellules phagocytaires constituent la première ligne de défense contre les pathogènes. Leur migration dirigée vers le site infectieux et leurs fonctions microbicides sont l'aboutissement de voies de signalisation intracellulaires sollicitées par la stimulation de récepteurs couplés aux protéines G, les récepteurs de chimioattractants. Après fixation du ligand et transmission du signal par la protéine G, les récepteurs sont phosphorylés et interagissent avec les b-arrestines, protéines d'échafaudage concourrant à l'internalisation des récepteurs. Plusieurs exemples récents suggèrent que les b-arrestines pourraient également participer à la signalisation. Le travail présenté dans ce mémoire concerne les récepteurs de la famille FPR (Formyl Peptide Receptor) et plus spécialement le récepteur FPRL1 (FPR-like 1), pour lesquels de nouveaux agonistes dérivant de protéines bactériennes ou mitochondriales humaines ont été identifiés. La phosphorylation du récepteur FPRL1 a été caractérisée. Il a été montré que les -arrestines interagissent avec celui-ci et qu'elles sont indispensables à son internalisation. Diverses approches ont conclu que l'activation rapide des MAP kinases ERK1/2, enclenchée par la stimulation du récepteur FPRL1, est majoritairement dépendante de la protéine G héterotrimérique et qu'il n'y pas de signalisation transmise par les b-arrestines. Enfin, une analyse protéomique des complexes multi-protéiques bâtis autour du couple FPRL1/b-arrestine a été menée par la méthode TAP (Tandem Affinity Purification). Le complexe adaptateur AP3, homologue d'AP2 a été identifié comme partenaire des b-arrestines après stimulation du récepteur FPRL1<br>Phagocytes are the first host defense line against pathogens. Their directed migration to infection sites and their microbicidal functions result from intracellular signaling cascades elicited by specific G protein-coupled receptors, the chemoattractant receptors. After ligand binding and G protein-mediated signaling events, receptors are phosphorylated and interact with the b-arrestins, which are scaffolding proteins participating to receptor internalization. Recent examples suggest that b-arrestins could also participate to signaling events. The work presented here is focused on the FPR family (Formyl Peptide Receptor) and specially the FPRL1 receptor (FPR-like 1), for which new agonists from bacterial origin or derived from human mitochondrial proteins have been identified. The phosphorylation of the FPRL1 receptor has been characterised and it has been shown that b-arrestins interact with this receptor and are essential to its internalization. Various approaches have concluded that the FPRL1-elicited rapid and transient activation of the MAP kinases ERK1/2 is mainly dependant on G protein and that there is no signaling events mediated by the b-arrestins. Finally, a proteomic study of the multiprotein complexes surrounded the couple FPRL1/b-arrestin has been conducted by the TAP method (Tandem Affinity Purification). The adaptor complex AP3, an homolog of AP2, has been identified as partner of b-arrestins after FPRL1 stimulation

Abstract:

Les leucocytes peuvent etre actives par des agents chimioattractants tels que des peptides bacteriens (fmlp) ou la fraction c5a du complement. Ces agents chimioattractants induisent la migration des leucocytes, leur degranulation et l'activation du complexe nadph oxydase qui produit les ions superoxyde impliques dans la destruction des pathogenes. Ces reponses cellulaires sont declenchees par la fixation de ces agents sur des recepteurs specifiques qui appartiennent a la superfamille des recepteurs couples aux proteines g heterotrimeriques. Malgre la presence continue d'agonistes, les reponses cellulaires sont transitoires et les cellules deviennent refractaires a une autre stimulation (desensibilisation homologue). Selon le concept actuel, le recepteur est phosphoryle, ce qui permet son interaction avec la proteine adaptatrice -arrestine. Cette interaction inhibe le couplage recepteur/proteine g et induit l'internalisation du recepteur par les puits recouverts de clathrine. Apres addition de c5a, le recepteur du c5a (rc5a) est phosphoryle sur six serines de la queue c-terminale intracellulaire. En utilisant des recepteurs dont certaines serines ont ete mutees, nous avons montre que : (1) cette phosphorylation suit un processus hierarchique, debutant par la phosphorylation des serines s334 et s332. (2) la phosphorylation de la serine s338 est necessaire au decouplage recepteur/proteine g. (3) le decouplage et l'internalisation de rc5a sont deux processus independants. (4) dans les cellules promyelocytaires hl-60, rc5a peut etre internalise par un mecanisme independant de la phosphorylation. Rc5a peut egalement etre internalise par la voie classique dependante de la phosphorylation. Ces deux mecanismes sont sensibles au dominant negatif de la dynamine, une gtpase qui intervient au niveau de la membrane dans la fermeture des vesicules d'endocytose, suggerant l'implication des puits recouverts de clathrine. D'autre part, nous avons identifie le peptide synthetique wkymvm comme un agoniste des recepteurs fpr, fprl1 et fprl2 ; wkymvm est specifique de fprl1 et fprl2. Un peptide antibacterien produit par helicobacter pylori (hp(2-20)) est egalement un agoniste de fprl1 et fprl2.

Abstract:

AbstractThis chapter explores the long trajectory of European feminists’ contributions to peace research. Specifically, the coalescing of knowledge via specific Centers of Excellence has supported the recent development of feminist peace research (FPR) in Europe. FPR has also been influenced by the global normative framework of the Women, Peace and Security agenda (WPS), which relies on research conducted outside of Europe. While the diversity of WPS informed research evidences a thriving FPR field in Europe, it also reveals the limitations of what constitutes ‘Europe.’ Ultimately, the chapter shows how FPR remains exclusionary, with implications for knowledge production hierarchies.

Abstract:

Abstract The Falling Particle Receiver (FPR) at the National Solar Thermal Test Facility (NSTTF) is a testbed for promising receiver technologies offering solutions to the temperature and irradiance limitations exhibited by gas and molten salt receivers, since the particle curtain is directly irradiated without the need of containment. Until recently, the heat loss of the NSTTF 1 MWth FPR was not fully characterized. One of the challenges of the FPR characterization is the intricate flow conditions that the particle curtain experiences due to its cavity design with a single open aperture, to allow the direct irradiance. Recently, particle plumes expelled from the FPR during operation were observed. While this phenomenon affects the FPR heat loss and needs to be closely monitored, it is extremely difficult to operate any kind of sensors near the aperture of the FPR. This work describes the development of a methodology using a high-speed IR camera, located ≥ 5 meters away from the aperture, to estimate the opacity of a particle plume, which in turn can be used to extract the average particle temperature of a region of interest with a known background temperature. Experiments performed at the University of New Mexico using four different flow configurations and three different temperatures (200, 450, and 750°C) were conducted to determine the relationship between the plume opacity in the visible range and the “particle-pixel” opacity obtained from thermograms in the IR range. We present a “particle-pixel function” that describes the combined impact of an unknown number of particles at a specific temperature on a thermogram pixel value with an initial value equal to the background temperature. The novelty of this function is that it provides a reasonable estimate of the plume opacity using thermograms obtained from the IR camera; hence a bulk particle temperature can be obtained. Future development of this methodology will make it possible to compute the advective losses from the FPR and provide a first order approximation of the convective losses for the system.

Full text

Abstract:

Ultrashort optical pulses with high repetition can be easily generated by directly modulated laser diodes. However, this method causes large frequency chirping which limits the bandwidth-distance product for high bit rate optical communication. Because the chirp-is nonlinear, it is difficult to obtain completely transform-limited pulses by using highly dispersive single mode fiber. Nakazawa et al1 experimentally obtained the transform-limit. ed pulses from a gain-switched DFB laser diode using a narrow-band F-P resonator (FPR), and transmited these pulses as soliton source for optical soliton communication2. However, Mollenauer et al3 asserted that such a source is also very likely to be subject to significant pulse-to-pulse frequency jitter, because no amount of filtering can completely eliminate chirp. In this paper, we will consider the dispersion of FPR, and it is showed that FPR could play the role not only in filtering but also in chirp compensation for gain-switched pulses. The transform-limited pulses can be obtained by designing parameters of FPR properly.

Abstract:

Majority of the pipeline operators manage corrosion using inline inspection (ILI). ILIs enable operators to choose which anomalies should be excavated and, on the flip side, which anomalies are safe to remain on the pipe. If the remaining anomalies grow to a critical size before the next ILI cycle there will be in-service failure. This is avoided by forecasting the growth of the measured defects appropriately and assessing them for future integrity. When an ILI is performed on a pipeline the ILI vendor reports the anomaly sizes, burst pressures and the Failure Pressure Ratios for each anomaly. Failure Pressure Ratio (FPR) for an anomaly is defined as the burst pressure divided by the Maximum allowable operation pressure (MAOP). In order to avoid ruptures, operators will excavate anomalies that have a limiting value of FPR. These limiting values are also referred to as response criteria, excavation criteria, safe failure pressure ratios, or safety factors. As the FPR depends heavily on the operating stress (or %SMYS) the limiting FPR value, below which we respond, should also depend on %SMYS. However, currently there is inconsistency in the use of response criteria in the industry. Some utilize the same response criteria for all pipe irrespective of %SMYS. This study shows that using the same limiting FPR does not provide the same level of safety for different %SMYS scenarios. It shows that the size of remaining anomalies in the lower %SMYS pipe would be significantly larger than in higher %SMYS pipe, leading to lower reliability in pipelines that have lower %SMYS. For gas pipelines, these lower %SMYS pipelines are often in higher location class pipelines with higher consequences of failure. In other words, even though the FPR value is the same for two anomalies in two different %SMYS pipes, the two anomalies would have very different probabilities of failure, where one anomaly could be safe while the other is not. This paper examines the ranges of FPR and the safe response criteria as a function of %SMYS. It examines the remaining anomaly sizes in different %SMYS pipe as allowed by current standards. The effect of the uncertainties on the response criteria due to measurement errors, material and geometric properties and model errors are also examined. It examines the response criteria in different jurisdictions. The effect of using different assessment equations, such as Modified B31G or RSTRENG, on the response criteria is also discussed. In order to obtain consistent safety, the consideration of %SMYS and consequences in defining a response criterion is discussed. Many sets of ILI data, which have pipe in different %SMYS, have been assessed in order to examine practical ranges of FPR with %SMYS. The practical implications of different response criteria are studied and discussed.

Abstract:

This study investigates the relationship between the failure pressure ratio (FPR) and implied reliability level for corrosion anomalies on natural gas transmission pipelines governed by the Canadian oil and gas pipeline standard CSA Z662-15 The model recommended in Annex O of CSA Z662-15 is adopted to evaluate the burst pressure capacity of a given corrosion anomaly on a pipeline, and the first-order reliability method (FORM) is used to evaluate the reliability index of the anomaly by considering uncertainties associated with the pipe geometric and material properties, ILI-reported anomaly sizes, operating pressure and accuracies of the burst pressure capacity models. The analysis results suggest that the FPR-reliability index relationship for pipelines with utilization factors greater than or equal to 0.72 is independent of the pipe attributes and geometry of the corrosion anomaly, if the measurement error associated with the ILI-reported anomaly depth is relatively small. Sensitivity analyses are carried out to examine the sensitivity of the FPR-reliability index relationship to the measurement error associated with the ILI-reported anomaly depth.

Abstract:

The blockerless cascade thrust reverser is one of the innovative thrust reverser systems, which replaces the traditionally mechanical blocker door with the aerodynamic blocker door by high-pressure secondary injection, thus significantly reduces the nacelle weight and the complexity of the actuator, and especially suitable for high-bypass-ratio turbofan engine. In order to obtain the optimum performance of a blockerless cascade thrust reverser system and provide the guidance for the design of the blockerless cascade thrust reverser system, a blockerless cascade thrust reverser system was studied in this paper based on the Response Surface Method (RSM), focusing on the effect of different geometric and aerodynamic parameters on the thrust reverser performance. Results show that the secondary injection with high pressure forms the blockage effect to the fan flow, then forces the fan flow to deflect and discharge from the cascade window, realizing the reverse thrust. The thrust reverser performance is mainly affected by fan pressure ratio (FPR), secondary flow pressure ratio (SPR), secondary injection position (Xjet), secondary injection angle (αjet) and cascade installation angle (β), and the dominated factors are FPR, SPR and Xjet. According to the obtained response equation of the thrust reverser performance, the relationship between reverse thrust efficiency and various parameters are clearly described, and performance of thrust reverser can be quickly evaluated. Significant interaction effects exist between different two factors, which must be taken into consideration in the design process of the blockerless cascade thrust reverser system, especially for the interaction effect between FPR and Xjet, interaction effect between FPR and β. Optimization design with objective of maximum reverse thrust was carried out to determine the best parameter settings, and reverse thrust ratio ηTrev of 60% is achieved under the constraint of the secondary flow ratio.

Abstract:

The American Petroleum Institute (API) initiated this project through Pipeline Research Council International, Inc. (PRCI), to apprise industry consensus recommended practices regarding reasonable and prudent crack in-line inspection (ILI) response criteria for hazardous liquid pipelines based on a comprehensive and informed consideration of current practices, processes, research, ILI performance and the industry's operating history. API Recommended Practice (RP) 1176, Assessment and Management of Cracking in Pipelines, are currently being prepared. A target date for a notice of proposed rulemaking (NPRM) from the U.S. Department of Transportation's (DOT) Pipeline and Hazardous Material Safety Administration (PHMSA) for Title 49 Code of Federal Regulation (CFR) and sect;195.452 has not been communicated at this time, however it is anticipated by the industry that an NPRM addressing changes to pipeline integrity management is forthcoming. The objective of this research is to substantiate API's stated depth and failure pressure ratio (FPR) response criteria applicable to ILI reported cracking anomalies in hazardous liquid pipelines, as well as facilitate operator and regulator technical insight sharing.
