Gieu, Jean-Baptiste. "Étude des interfaces électrode/électrolyte des batteries lithium-ion : cas de l'électrode à base de Li4Ti5O12." Thesis, Pau, 2016. http://www.theses.fr/2016PAUU3043/document.
Abstract:
Les batteries lithium-ion (Li-ion) sont privilégiées dans de nombreuses applications comme solution de stockage de l’énergie. Le composé Li4Ti5O12 (LTO) est une alternative au graphite qui demeure majoritairement utilisé comme matériau d’électrode négative dans les batteries Li-ion. Pour de potentielles applications à haute température, il est nécessaire d’étudier les couches interfaciales qui se forment dans ces conditions en surface des électrodes LTO. En effet, la formation de telles couches est un phénomène commun aux batteries Li-ion, dont la maîtrise revêt un rôle fondamental pour l’obtention de bonnes performances électrochimiques. La surface des électrodes LTO a pour cela été principalement caractérisée par Spectroscopie Photoélectronique à rayonnement X (XPS) et des analyses complémentaires ont aussi été ponctuellement menées en microscopie Auger à balayage (Scanning Auger Microscopy : SAM) pour l’acquisition de cartographies élémentaires et en spectrométrie de masse d’ions secondaires à temps de vol (Time-of-Flight Secondary Ions Spectrometry : ToF-SIMS) pour établir des profils de concentration élémentaires et moléculaires en profondeur. Ces résultats ont été systématiquement confrontés aux données électrochimiques. L’influence de différents paramètres sur les propriétés de la couche interfaciale formée en cyclage face au lithium a été évaluée. Une comparaison des couches interfaciales formées au premier cycle à température ambiante, 60 °C et 85 °C a ainsi montré qu’une température de cyclage plus élevée favorise la formation d’une couche interfaciale plus épaisse. L’utilisation d’un électrolyte contenant l’additif VC accélère la formation d’une SEI plus épaisse dès le premier cycle, moins sujette au phénomène de dissolution au cours de la délithiation et susceptible d'améliorer la rétention de capacité en longs cyclages. La substitution du sel de lithium LiPF6 par le sel LiTFSI entraîne la formation d’une couche plus fine, ce qui est principalement dû à une quantité de LiF déposée plus faible. De manière similaire, la substitution des solvants EC:DMC par les solvants PC:EMC, induit la formation d’une couche plus fine, du fait d’une quantité moins importante de LiF déposée. Par ailleurs, plus la surface spécifique de l’additif carboné entrant dans la composition des électrodes est élevée, plus la part de LiF parmi les espèces de la couche interfaciale formée est élevée, sans que cela n’influence son épaisseur. Puis, le comportement des interfaces électrode/électrolyte dans une batterie LiMn2O4/Li4Ti5O12 a finalement été étudié. Une couche interfaciale se forme en surface des deux électrodes. Néanmoins la couche formée sur l’électrode positive est plus fine que celle formée sur l’électrode négative. Leur composition est similaire, à l’exception du composé MnF2 uniquement détecté sur l’électrode négative et provenant d’un phénomène de dissolution du matériau LiMn2O4. Un prolongement de ce travail peut être envisagé concernant des électrodes à base de particules LTO avec différents coatings. De plus, une synergie systématique entre les trois techniques utilisées dans cette thèse pourra être encouragéeLithium-ion (Li-ion) batteries have been considered as the solution of choice for energy storage in numerous applications. Li4Ti5O12 (LTO) compound is an alternative to the widely used graphite, as a negative electrode material. For potential high temperature applications, the study of interfacial layers formed on top of LTO electrodes in such conditions is a necessary step. The formation of such surface layers is commonly observed in lithium-ion batteries and their properties are critical for maintaining good batteries performances. Therefore, LTO electrodes surfaces were mainly analyzed by X-ray Photoelectron Spectroscopy (XPS) and complementary measurements were performed by Scanning Auger Microscopy (SAM) for the acquisition of elemental mappings and by Time-of-Flight Secondary Ions Spectrometry (ToF-SIMS) for depth profile analysis. Surface analysis results were systematically linked to electrochemical data. The influence of several parameters was investigated for LTO electrodes cycled versus lithium. The comparison of surface layers formed during the first cycle at room temperature, 60 °C and 85 °C showed that higher cycling temperatures induce the formation of a thicker layer. The use of a VC-containing electrolyte accelerates the formation of a thicker layer since the first cycle, less prone to dissolution during delithiation and susceptible to enhance the capacity retention for long cycling. Substitution of LiPF6 lithium salt by LiTFSI leads to the formation of thinner layer, which is mainly due to a lower amount of deposited LiF. Similar results are obtained for the substitution of EC:DMC solvants by PC:EMC. Furthermore, the higher the specific surface of the electrode carbonaceous additive is, the higher the share of LiF in the interfacial layer composition is, even if its thickness remains similar. Finally, the behavior of electrode/electrolyte interfaces was studied in a LiMn2O4 /Li4Ti5O12 full cell. Interfacial layers are formed on the surface of both electrodes. Nevertheless, the layer on the positive electrode is thinner than the one on the negative electrode. Their composition are similar except for MnF2 compound, coming from LiMn2O4 dissolution at the positive electrode, which is only detected on the negative electrode. This work could be continued with the study of electrodes based on coated LTO particles. Moreover, a greater synergy between three characterization techniques used in this work could be promoted

Zerrouki, Alan. "Compréhension et Optimisation du Procédé de Dépôt par Électrophorèse en Mode Pulsé en Milieu Aqueux de Nanoparticules Modèles et d'Intérêt Industriel." Electronic Thesis or Diss., Bourgogne Franche-Comté, 2024. http://www.theses.fr/2024UBFCK010.
Abstract:
Ce travail de thèse s’inscrit dans le cadre d’une problématique industrielle visant à réaliser par voie électrophorétique des dépôts d’épaisseur micrométrique de matériaux d’électrodes de batterie au lithium. En raison de contraintes posées par l’utilisation de solvants organiques pour formuler à grande échelle des suspensions de nanoparticules céramiques, le procédé EPD (ElectroPhoretic Deposition) envisagé dans le contexte de ce travail fait appel à des suspensions colloïdales en milieu aqueux, ainsi qu’à une polarisation en régime pulsé afin de limiter le phénomène d’électrolyse de l’eau néfaste à l’obtention de dépôts denses.L’objectif de cette étude est d’optimiser le procédé EPD en termes de vitesse et de qualité de dépôt, en faisant appel à des suspensions modèles de nanoparticules de silice. Ainsi les conditions de synthèse de ces particules obtenues par la méthode Stöber ont été optimisées pour conférer aux nanoparticules des caractéristiques géométriques et physico-chimiques (potentiel zêta, point isoélectrique) très similaires aux nanomatériaux d’intérêt industriel.Les cinétiques de dépôt par EPD ont été simulées à travers un premier modèle par éléments finis et comparées à des retours d’expériences tant sur les suspensions monodisperses de nanoparticules de silice que sur des suspensions polydisperses de matériaux d’électrodes d’intérêt industriel. Un second modèle électrochimique a permis de simuler l’évolution du pH en surface d’électrode en régime pulsé et d’apporter une meilleure compréhension du procédé. L’hypothèse d’un mécanisme étendu de la théorie DLVO incluant une diminution du pH résultant de l’oxydation de l’eau a été mis en évidence dans le domaine des basses fréquences du régime pulsé. De plus, il a été montré que cette acidification peut être limitée en diminuant la valeur du rapport cyclique, donc en augmentant la période de relaxation du potentiel en régime pulsé, et en opérant à hautes fréquences (f > 1000 Hz).Finalement, une attention particulière a été portée sur la fissuration des dépôts qui intervient au cours de l’étape de séchage. L’utilisation de suspensions modèles polydisperses ou de conditions de séchage à humidité relative élevée ont permis d’améliorer la qualité des dépôts sans pour autant éliminer les fissures. En revanche, la résorption partielle des fissures a été observée en incorporant un polyélectrolyte anionique (la gomme xanthane) non adsorbé en surface des nanoparticules de silice ou un polymère neutre (le polyéthylène glycol, PEG) ayant une forte affinité pour la siliceThis thesis work is part of an industrial issue aiming to achieve micrometer-thick deposits of lithium battery electrode materials by electrophoretic deposition. Due to constraints related to the large-scale use of organic solvent suspensions of ceramic materials, the EPD (ElectroPhoretic Deposition) process considered in the context of this work involves colloidal suspensions of nanoparticles in an aqueous medium, as well as pulsed polarization to limit the harmful water electrolysis phenomenon in obtaining dense deposits.The objective of this study is to optimize the EPD process in terms of deposition yield and quality, using model suspensions of silica nanoparticles. Thus, the synthesis conditions of these particles obtained by the Stöber approach, were optimized to get geometric and physico-chemical characteristics (zeta potential, isoelectric point) very similar to the industrial materials of interest.The deposition kinetics by EPD were simulated through a first finite element model and compared to experimental data on both monodisperse silica nanoparticle suspensions and polydisperse suspensions of industrial electrode materials.A second electrochemical model allowed simulating the evolution of pH at the electrode surface in pulsed mode and providing a better understanding of the process. The hypothesis of an extended mechanism of the DLVO theory including a decrease in pH resulting from water oxidation was highlighted in the low-frequency range of the pulsed regime. Furthermore, it was shown that this acidification can be limited by decreasing the duty cycle, thus increasing the relaxation period of the potential in pulsed mode, and operating at high frequencies (f > 1000 Hz).Finally, particular attention was focused on the cracking of deposits that occurs during the drying stage. The use of polydisperse model suspensions or drying conditions at high relative humidity improved the quality of the deposits without eliminating the cracks. However, incorporating an anionic polyelectrolyte (xanthan gum) that is not adsorbed on the surface of silica nanoparticles or a neutral polymer (polyethylene glycol, PEG) having a high affinity for silica induced a partial decrease of the cracks

Lester, Krystal L. "Characterisation of Oncogenic LMO Transcriptional complexes." Thesis, The University of Sydney, 2015. http://hdl.handle.net/2123/13754.
Abstract:
The LIM only (LMO) family of proteins are transcriptional regulators that are critical for the regulation of many developmental processes. In early red blood cell development one family member, LMO2, regulates blood cell development (erythropoiesis) through involvement in a transcriptional complex that also contains Tal1, E2a proteins, Gata1 and LDB1. Two components of this complex, Tal1 and LMO2, along with their homologues Lyl1, LMO1 and LMO3, are oncogenes in T cell acute lymphoblastic leukaemia (T ALL). Complexes similar to the erythropoietic LMO2 transcriptional complex are thought to drive the onset of T ALL. This thesis investigates the protein protein interactions of potential constituents of both normal and oncogenic complexes. A full set of tethered LMO-LDB1 sub-complexes was designed, generated, purified and characterised using SEC/MALLS, CD spectropolarimetry and 1D 1H-NMR. The proteins were folded, predominantly monomeric and may be more stable than previously generated versions. Attempts to crystallise the previously uncharacterised LMO1-LDB1 and LMO3-LDB1 constructs are described. GST-pulldown and EMSA experiments were used to show that LMO1–3-LDB1 but not LMO4 LDB1 can bind to Tal1 E2a and Lyl1 E2a heterodimers in the absence of DNA and to characterise heterodimer DNA binding of the higher order complex. These data indicate that the bHLH proteins likely undergo dimer exchange, such that in the presence of DNA, Tal1 E2a proteins form substantial amounts of homodimers as well as heterodimers, but heterodimer formation is favoured by interaction with LMO-LDB1 proteins. No evidence of Lyl1 E2a heterodimer formation on DNA was observed by EMSA, but this heterodimer was stabilised through higher order complex formation with LMO2-LDB1. Binding affinities of LMO1–4-LDB1 to Tal1 E2a heterodimers indicate no binding by LMO4 and similar levels of binding for LMO1–3-LDB1. A protein engineering approach was thus used to generate more stable extended Tal1 E2a constructs, which would be useful for further characterisation of these interactions. Finally, it was shown that Gata2 and Gata3 bind with similar, but slightly lower affinity to LMO2. Also, only the C-terminal finger of Gata1 shows appreciable independent binding to DNA containing GATC/G motifs. The implications of this data for the mechanisms of transcriptional complex formation, and how variant complexes can up- and down-regulate different sets of genes throughout normal development and T-cell leukaemia are discussed.

Gonzalez, Ricardo. "Leo." Thesis, California State University, Long Beach, 2016. http://pqdtopen.proquest.com/#viewpdf?dispub=10096082.
Abstract:
Leo is a collection of short stories linked by the character, Leo. The stories follow Leo through different times, settings, and episodes in his life. In this collection, in the quest to understand the meaning of the self and individual, Leo attempts to learn the difference between good and bad and life and death. The stories feature odd family members, troubled relationships, and self-destructive coping mechanisms. Written in different narrative styles, the collection attempts to create a marriage between content and form with special attention to language. My stories hope to explore questions about cultural identity, emotional stability, and loss of innocence.

Peltier, Anatole-Roger. "Le roman classique lao." Paris 3, 1986. http://www.theses.fr/1986PA030062.
Abstract:
Les romans classiques lao sont, pour la plupart, des versifications de contes epiques. Ils sont principalement destines a etre lus devant un auditoire, lors des veillees. Il en existe plus d'une centaine de titres sous forme de manuscrits et beaucoup de ces manuscrits, consistant en feuilles de latanier gravees en caracteres lao anciens, ont ete edites sous forme de brochures imprimees en caracteres lao modernes, depuis 1957, surtout par le comite litteraire, l'academie royale et la bibliotheque nationale lao. L'etude des sources montre que ces romans s'inspirent de la litterature indienne, de la litterature yuan, de la litterature du vieux fonds indochinois, de la litterature siamoise et du pannasajataka, un recueil de jataka apocryphes d'origine mone. Les romans purement lao et ayant un caractere original sont des romans historiques. Bien qu'appartenant a la litterature laique, ou domine d'ailleurs le merveilleux, les romans lao sont fortement impregnes par les enseignements bouddhiques et les themes developpes tournent autour du dharma et du karma. Il s'agit, en fait, d'un bouddhisme populaire qui ne cherche qu'a inculquer les preceptes de base a la grande masse des habitants. Depuis 1975, date de l'instauration de la republique democratique et populaire lao, les romans les plus connus et les plus apprecies font l'objet de recuperation de la part des nouvelles autorites pour illustrer leurs themes politiques, comme ils le furent jadis par les moines pour repandre l'enseignement bouddhiqueThe most of lao classic tales are the epic poems. They are principally intended to be read in front of the public, in the evenings. There are more than one hundred stories in palmleaves manuscript forms which are engraved with the old lao characters. Some of these manuscripts have been printed in modern lao characters since1957, especially by the literary committee, the royal academy and the lao national library. The study of these origin tales shows that they were inspired by the indian literature, the yuan literature, the old indochinese fund literary, the siamese literature and the pannasajataka, the collection of apocryphal jataka coming from the mon civilization. The lao classic purely tales which have the original characters, are the historic stories. Although these tales belonged to the laic literature in which "the marvellous" dominated, they are impregnated by the buddhist teaching and the developped topics turned around the dharma and the karma. It concerns, in fact, that the popular buddhism finds to inculcate the basic precepts for the large population. Since 1975, date of the lao people's democratic republic instauration, the most well know tales are recuperated by new government to illustrate the political topics, as the classic tales were widespread for the buddhist teaching by the monks in the past

Abstract:
Como una profesional involucrada con la formación educativa de la niñez y, en especial, con aquella perteneciente al centro poblado de Serrán donde ejerzo la docencia he creído por conveniente desarrollar esta investigación conocedora de la situación actual por la que atraviesan los educandos de la Institución Educativa N° 14663, en cuanto a la comprensión lectora se refiere. Al respecto, he desarrollado un Plan de Acción que basa su explicación en la problemática de la comprensión lectora entre los alumnos de la IE antes indicada denominado “LEO, COMPRENDO Y APRENDO”. Siendo, entonces el objetivo principal que busca mi investigación mejorar el nivel de comprensión lectora de los estudiantes de la I.E. N°14663 de Serrán, para lo cual tienen que asumir un compromiso social tanto los estudiantes, como los docentes, los padres de familia y, los directivos. He podido identificar una diversidad de causas, tales como: Pocas estrategias para la comprensión lectora por parte del docente; pocos hábitos de lectura en los alumnos; desconocimiento para elaborar material educativo que promueva la comprensión lectora por parte del docente; el docente no elabora el material educativo adecuado debido a que no está preparado para construir tales elementos, como por ejemplo, fichas de lectura. Desarrollaré este plan de acción basándome en las teorías de Treviño, Pedroza, Pérez, Ramírez y, Ramos en su experiencia exitosa denominada “Practicas docentes `para el desarrollo de la comprensión lectora en primaria” y también en la de Rita Castillo contenida en su experiencia del “Cuentito Viajero”. Espero que la puesta en marcha del plan de acción permita que los estudiantes de la I.E. N° 14663 enfrenten la comprensión en las competencias de comunicación y matemáticas como la resolución de problemas, obteniéndose mejores resultados en los indicadores de comprensión lectora y resolución de matemáticas.Trabajo académico

Abstract:
Questo lavoro ha lo scopo di illustrare l’enigmatica presenza del filosofo Leo Strauss all’interno del movimento Neoconservatore, a cui è stato collegato svariate volte, soprattutto dai media giornalistici, ma anche da alcuni lavori accademici. Si è analizzato in primo luogo la posizione del filosofo, soffermandosi su alcuni dei suoi testi cardine. Si è anche preso in considerazione il legame tra Strauss e alcuni pensatori “problematici”, come Martin Heidegger e Carl Schmitt. Nel secondo capitolo si è cercato di chiarire la posizione di Strauss riguardo gli USA, e come da una serie di tesi apparentemente contradditorie egli sia riuscito ad approdare ad una visione positiva su di essi. Si è inoltre fornito un esempio, per il tramite di un testo di Thomas Pangle, di come gli allievi del Filosofo abbiano approfondito la posizione straussiana nei confronti dell’America, andando a ricercarne le origini. Il terzo capitolo ha approfondito invece la questione del legame tra Strauss e la Destra americana, come la sua posizione sia stata criticata e come essa sia stata traghettata da alcuni pensatori (Bloom e Fukuyama) fino al pensiero neoconservatore, non però senza una sostanziale modifica. Il capitolo finale si è occupato di trattare una breve storia del Neoconservatorismo, dalle sue origini fino alla Presidenza Bush, soffermandosi anche su colui che ne viene definito il padre fondatore, Irving Kristol.

Abstract:
The fourth generation cellular mobile broadband, Long-Term Evolution (LTE), provides high speed Internet via Internet Protocol (IP). Today’s wireless infrastructure paves the way to a connected society where high speed Internet is seamlessly available at all times for anyone to use. To achieve this, a mobile service subscriber can no longer be bound to a single network provided by a single operator. Thus, roaming constitutes a key pillar in shaping the connected society Local Breakout (LBO) Voice over Long-Term Evolution (VoLTE) roaming enables a mobile service subscriber to breakout from its home network, and to use network services in a visited network. LBO requires control signalling and user data to be routed over several Public Land Mobile Networks (PLMNs), thus making mobile service subscriber’s the subject of Lawful Intercept (LI) across multiple networks. This thesis project investigates the possibility of using Multimedia Internet KEYing (MIKEY) and Secure Real-Time Transport Protocol (SRTP) to encrypt the payload of VoLTE media packets. More specifically, a Law Enforcement Monitoring Provider (LEMP) is designed, implemented, and evaluated. LEMP is deployed within a cell phone and serves to distribute cryptographic key shares to Trusted Third Parties (TTPs), i.e. multiple escrow agents, entrusted to store these cryptographic key shares. The result preserves the requirements for LI despite the fact that there may be multiple network operators involved. Moreover, the experiments show that the distribution time depends primarily on network latency rather than the time required to split the cryptographic key in chunks; hence the approach is usable in practice.Den fjärde generationens mobila bredband, Long-Term Evolution (LTE), möjliggör användandet av höghastighetsinternet över Internet Protocol (IP). Dagens trådlösa infrastrukturer banar väg för ett fritt och lättillgängligt digitalt samhälle där alla kan vara uppkopplade samtidigt. För att uppnå global trådlös infrastruktur måste mobilabonnenten ha möjlighet att utnyttja flera andra trådlösa nätverk än det nätverk som teleoperatören binder dem till. Därför utgör fri roaming en viktig del i utvecklingen av framtidens globala trådlösa infrastrukturer. Local Breakout (LBO) Voice over Long-Term Evolution (VoLTE) är en roamingarkitektur som gör det möjligt för en mobilabonnent att kopplas upp från en teleoperatörs nät till en annans. LBO kräver att kontrollsignaler och användardata skickas mellan flera operatörer innan trafiken når sitt mål, och därmed utsätts mobilabonnenten för laglig avlyssning av elektronisk information på flera platser samtidigt. Det här examensarbetet undersöker möjligheten att använda Multimedia Internet KEYing (MIKEY) och Secure Real-Time Transport Protocol (SRTP) för att kryptera mediatrafik i VoLTE. Under arbetets gång utvecklas och utvärderas en Law Enforcement Monitoring Provider (LEMP). LEMP är placerad i en mobiltelefon och distribuerar delar av krypteringsnycklar till flera betrodda tredje parter (till flera escrow agents). Detta gör det möjligt att uppfylla kraven för laglig avlyssning av elektronisk information även när flera teleoperatörer avlyssnar användardata och kontrollsignaler. Resultatet visar att distribueringstiden primärt beror på nätverkslatens, och inte på den tid det tar att fördela krypteringsnyckeln i mindre delar. Därför kan den här metoden användas i praktiken.

Abstract:
In this master’s thesis, design topologies and challenges of low-power, integrated low-dropout regulators have been studied. Various topologies have been examined and compared. Low-dropout regulators are commonly used in multitude of applications, ranging from high-power systems to battery powered mobile devices. The advantages of low-dropout regulators include simplicity, low noise and low input-output voltage drop. The main challenge in designing modern low-dropout regulators is achieving a high current efficiency by reducing the quiescent current consumption of the system. In addition, the compensation of regulators is challenging when the load current varies on a high dynamic range. This thesis concentrates on designing an integrated low-dropout regulator with high dynamic range, good regulation performance and high current efficiency. Based on the topology study, the regulator was designed around a class AB error amplifier, the main advantage of which is the independency between the quiescent and output currents. High dynamic performance on large load currents was achieved by utilizing an adaptive biasing circuit for the amplifier. In addition, a switched feedback resistor network was designed in order to adjust the output voltage and improve the dynamic performance. The selected circuit topologies were used to design and simulate a fully integrated implementation and a regulator with an external capacitor in order to supply current for a digital loadTässä diplomityössä on tutkittu matalatehoisten, integroitujen low-dropout -regulaattorien rakenteita sekä suunnitteluhaasteita. Työssä tutkittiin ja vertailtiin erilaisia toteutustopologioita. Low-dropout -regulaattoreita käytetään monenlaisissa sovelluksissa ulottuen korkeatehoisista järjestelmistä akkukäyttöisiin mobiililaitteisiin. Low-dropout -regulaattorien etuihin kuuluvat yksinkertaisuus, matala kohina sekä pieni tulon ja lähdön välinen jännite-ero. Modernien low-dropout regulaattorien pääasialliset suunnitteluhaasteet kohdistuvat korkean virtahyötysuhteen saavuttamiseen pienentämällä lepovirtaa. Lisäksi regulaattorien kompensointi on haasteellista kun lähtövirran vaihtelualue on laaja. Työssä on keskitytty suunnittelemaan integroitu regulaattori, jolla on laaja lähtövirran vaihtelualue, hyvä regulointikyky sekä korkea virtahyötysuhde. Topologiavertailun perusteella regulaattori suunniteltiin käyttäen AB-luokan virhevahvistinta, jonka hyöty on biasvirran ja lähtövirran riippumattomuus toisistaan. Korkea dynaaminen suorituskyky suurilla kuormavirroilla saavutettiin käyttämällä vahvistimen biasoinnissa adaptiivista biaspiiriä. Lisäksi työssä suunniteltiin kytketty vastusverkko lähtöjännitteen säätämiseksi sekä suorituskyvyn parantamiseksi. Valittuja toteutustopologioita käyttämällä suunniteltiin kokonaan integroitu regulaattori sekä erillinen toteutus ulkoisella lähtökondensaattorilla jotta regulaattori pystyisi ajamaan digitaalista kuormaa

de este proyecto es lograr que los docentes apliquen adecuadas estrategias para la
comprensión literal de textos narrativos, la construcción del proyecto tiene dos partes:
Marco conceptual y el diseño del proyecto. Los conceptos que sustentan la
innovación son, los textos narrativos que nos permiten comprender, comunicar
nuevas ideas a los demás, la comprensión lectora al leer las personas reaccionan
frente al texto, imaginando e interpretando o construyendo una idea de su posible
significado, estrategias didácticas de comprensión lectora son procesos ejecutivos,
ligados a tareas muy concretas, y conceden a las estrategias propias el carácter de
capacidades cognitivas de orden más elevado, los niveles de comprensión:
comprensión literal que se encuentra explicita en el texto, comprensión inferencial
que se encuentra implícita en el texto, comprensión crítica asumir una posición frente
al texto. Para la construcción del proyecto de innovación educativa elaboré el FODA
teniendo en cuenta, las fortalezas, debilidades, oportunidades y las amenazas de mis
estudiantes, contando con este material elaboré el árbol de problemas, el árbol de
objetivos, la matriz de consistencia, el objetivo general, el objetivo central, la
estructura del perfil del proyecto de innovación educativa, el marco conceptual. Al

Abstract:
Este proyecto de innovación educativa denominado “Leo, comprendo, resuelvo y

presentado en los niños y niñas del segundo grado de primaria de la I.E. N° 145
Independencia Americana, en quienes se ha podido ver una marcada deficiencia en la
resolución de problemas matemáticos, ubicándolos específicamente en los problemas de
igualación: como producto de los resultados obtenidos en los exámenes ECE que son
aplicados por el Ministerio de Educación durante el año académico y cuyos resultados han
reflejado niveles de logro no esperados, ya que dentro de los aprendizajes esperados para
la institución y orientados por los porcentajes alcanzados el año anterior surge un
problema que desestabiliza el desempeño y capacidad de nuestros niños y niñas en
cuanto a esta competencia.
Ante este impase como institución nos hemos propuesto la ejecución de este
proyecto de innovación buscando que los docentes del segundo grado apliquen estrategias
metodológicas con nuestros niños y niñas que ayuden a promover habilidades, generando
interés y movilizando capacidades matemáticas para trabajar eficientemente el enfoque de
resolución de problemas.
Al investigar sobre cómo resolver problemas matemáticos se ha encontrado a
muchos investigadores, científicos matemáticos que han realizado una serie de estudios
tratando de encontrar la forma más fácil de enseñar a sus alumnos y son los que dan
sustento a este trabajo; entre ellos podemos citar a Polya (1945), Kilpatrick (1967), Santos
(2007), Schoenfeld (1985), (1992), Postman y Weingartner (1969), Lester y Kehle (2003),
Lesh y Kelly (2000), Cobo y Fortuny (2000), Puig (1996), todos ellos tienen muchos
puntos de coincidencia al afirmar que cuando los estudiantes tratan con tareas o
problemas que les son significativos, desencadenan ideas matemáticas fundamentales
teniendo disposición, poniendo en juego sus creencias y actitudes, así como sus
antecedentes y experiencias y que es el salón de clases el que debe promover actividades
y hábitos consistentes con la práctica real de la resolución de problemas.
Por lo tanto se espera que con la ejecución del presente proyecto los docentes
puedan planificar, programar y desarrollar unidades de aprendizaje que activen en
nuestros niños y niñas capacidades matemáticas para resolver problemas promoviendo su
participación activa y asegurándose de elevar su desempeño y formar seres competentes
y comprometidos con el proceso de enseñanza aprendizaje dentro del enfoque de
Resolución de Problemas, cumpliendo de esta manera con dar solución al problema que
se tiene a nivel institucional.Trabajo académico

Abstract:
This diploma thesis deals with the acquisition of companies by means of the Leveraged Buyout (LBO) method. This method differs in many respects from the standards M&A. This work examines the specific features of the given business transactions from the viewpoint of the target companies, procedures and entities involved in these transactions. As the key element of the LBO method is the debt financing of the acquisition, the work also deals with this aspect and evaluates the positions of the creditors from the viewpoint of the influence on the stability of the financial system. The thesis further analyses the question whether the LBO method has an effect leading to an increased effectiveness of processes in a company, or whether, conversely, the proceeds of acquisition investors are a consequence of a transfer of values from other entities. The text is based on available theoretical and empirical sources which are supplemented by the author's analyses.

Abstract:
Problématique : À l'instar de beaucoup de pays en développement, la qualité des services offerts dans les hôpitaux de la RDP Lao, surtout périphériques, est souvent critiquée. Il est dès lors intéressant d'examiner les cas "à succès", ceux dont on considère qu'ils devraient être des modèles pour le pays. Tel est le cas de 2 hôpitaux de la province de Vientiane, dont le développement a été soutenu par la Coopération luxembourgeoise. Méthodologie: Cette étude est une étude de cas multiples portant sur deux hôpitaux (Maria Teresa et Vang Vieng). Elle visait à étudier les facteurs organisationnels associés à la perception par les travailleurs en santé et les femmes enceintes ou en post-partum, de la performance des soins obstétricaux offerts dans ces hôpitaux. Des entrevues individuelles, basées sur des thématiques découlant du cadre conceptuel de l'étude ont été réalisées. Résultats : L'analyse des résultats montrent une grande satisfaction tant de la part des travailleurs des hôpitaux que des utilisatrices de services, avec les services offerts, même si certains services attendus ne sont pas systématiquement offerts. Les principaux facteurs associés à la fonctionnalité perçue des deux hôpitaux sont liés à deux aspects : un investissement dans les ressources humaines et un investissement dans l'accessibilité de population-cible aux services obstétricaux. L'investissement en ressources humaines a porté sur des stratégies visant l'expertise de tous, cliniciens et non cliniciens, la valorisation du travail du personnel et la création d'une ambiance d'équipe plaisante. L'investissement dans l'accessibilité a porté sur les barrières géographiques et économiques, ainsi que sur la diffusion d'information dans la communauté sur l'importance des soins périnatals. Conclusion : Un investissement dans les ressources humaines et l'accessibilité aux services permet aux hôpitaux régionaux de la RDP Lao de devenir fonctionnels et performants. Mots clés : soins obstétricaux, coopération luxembourgeoise, qualité des services de santé, ressources humaines, RDP Lao.Problematic: Like many developing countries, the quality of services provided in Lao hospitals, especially in remote regions, is often criticized. It is therefore interesting to examine "successful" cases hospitals that are considered by many as models for the rest country. Such is the case of two hospitals in the province of Vientiane, whose evolution was supported by Luxembourg Cooperation. Methodology: This study is a multiple case study took place in two hospitals (Maria Teresa and Vang Vieng). It aimed to study organizational factors associated with the perception by health workers and pregnant or postpartum, of the performance of obstetric care. Individual interviews, based on themes derived from the conceptual framework of the study were performed. Results: Analyses of the results show a great satisfaction with the services offered by both, hospital workers and users, even if some expected services are not routinely offered. The main factors associated with the perceived functionality of the two hospitals are related to two aspects: an investment in human resources and an investment in the accessibility of the target population to obstetric services. The investment in human resources focused on strategies aiming the improvement of the expertise detained by all, clinicians and non-clinicians, the recognition of the work done by the staff and the creation of a pleasant atmosphere for team work. Investment in accessibility focused on geographical and economic barriers, as well as on providing information on the importance of perinatal care to the community. Conclusion: An investment in human resources and in the accessibility to services allows regional hospitals of the Lao PDR to become functional and efficient. Key words: Obstetric care, Luxembourg cooperation, quality of care, human resources, RDP Lao.

Previous issue date: 2010-09-06The Oil industry in Brazil has gone through several stages during the economical, political and social historical process. However, the significative changes have happened in the last fifteen years, due to market opening arising from the relaxation of the state monopoly over the Oil deposits and its derivatives. The edition of the Constitutional Amendment #9, changing the first paragraph of the 177th item of the Federal Constitution, marked the end of a stiffness about the monopoly that the Brazilian state kept in relation to the exploration and research of Oil and Gas. The economical order was fundamental to actualize the idea contained in the #9 Amendment, since its contents has the power to set up measures to be adopted by public power in order to organize the economical relations from a social viewpoint. The new brazilian Oil scenery, called pre-salt, presents itself in a way to amaze the economical markets, in addition to creating a new perspective to the social sector. This work will identify, in this new scenario, the need for change in the legal system. Nevertheless, this subject must not be treated in a thoughtless way: being an exhaustible good, we shall not forget that the future generations also must benefit from the exploration of natural resources recently discovered. The settlement of a new regulatory mark, including the change in the concession contract model to production and sharing is one of the suggested solutions as a bill in the National Congress, in an attempt to ensure the sovereignty of the nation. The constitutionality of a new regulatory mark is questioned, starting from an analysis of the state monopoly, grounding the comprehnsions in the brazilian constitutions, the relevance of the creation of Petrobras for self-assertion of the state about the monopoly of Oil and derivatives, and its posture after the Constitutional Amendment n? 9 (1995), when a company stops having control of the state monopoly, beginning to compete in a fairly way with other companies. The market opening and private initiative are emphasized from the viewpoint of the Constitutional Principles of the Economical and Social Order. The relaxation of the monopoly regarding the exploratory activity in the Federal Constitution doesn't deprive from the Union the ownerships of underground goods, enabling to this federal entity to contract, directly or by concession of exploration of goods, to state-owned or private companies. The existing oil in the pre-salt layer transforms the scenario from very high risk to low risk, which gives the Union the possibility of defining another way of exploring this resources in the best interests of the Public Administration
A ind?stria do petr?leo no Brasil passou por v?rias etapas durante o processo hist?rico econ?mico, pol?tico e social. Todavia, suas significativas mudan?as ocorreram nos ?ltimos quinze anos, atrav?s da abertura do mercado decorrente da flexibiliza??o do monop?lio estatal sobre as jazidas de petr?leo e seus derivados. A edi??o da Emenda Constitucional n? 9, alterando o par?grafo 1?, do art. 177 da Constitui??o Federal, caracterizou o fim de uma rigidez quanto ao monop?lio que o Estado brasileiro mantinha em rela??o ? pesquisa e explora??o de petr?leo e g?s. A ordem econ?mica foi fundamental para efetivar a id?ia contida na Emenda n? 9, visto que seu conte?do tem o cond?o de estabelecer medidas a serem adotadas pelo poder p?blico a fim de organizar as rela??es econ?micas, sob o vi?s social. O novo cen?rio petrol?fero brasileiro, denominado pr?-sal, apresenta-se de forma a surpreender os mercados econ?micos, al?m de criar uma nova perspectiva para o setor social. O presente trabalho identificar? no novo cen?rio a necessidade de mudan?a do regime jur?dico, todavia, esse assunto n?o pode ser tratado de forma imediatista: como se trata de um bem esgot?vel n?o se deve esquecer que as gera??es futuras tamb?m precisam beneficiar-se da explora??o dos recursos naturais rec?m-descobertos. O estabelecimento de um novo marco regulat?rio, incluindo a mudan?a do modelo de contrato concess?o para produ??o e partilha ? uma das solu??es propostas a n?vel de projeto de lei no Congresso Nacional na tentativa de garantir a soberania da na??o. Questiona-se a constitucionalidade de um novo marco regulat?rio, partindo-se da an?lise do monop?lio estatal, resgatando a compreens?o nas constitui??es brasileiras, a relev?ncia da cria??o da Petrobras para auto-afirma??o do Estado quanto ao monop?lio de petr?leo e derivados, e sua postura ap?s a Emenda Constitucional n? 9 de 1995 quando a empresa deixa de ter o controle do monop?lio estatal, passando a concorrer de forma igualit?ria com outras empresas. Ressalva-se a abertura do mercado e a iniciativa privada sob ?tica dos Princ?pios Constitucionais da Ordem Econ?mica e Social. A flexibiliza??o do monop?lio quanto a atividade explorat?ria na Constitui??o Federal n?o retira da Uni?o a propriedade dos bens do subsolo, possibilitando a este ente federal a contrata??o direta ou atrav?s de concess?o da explora??o do bem a empresas estatais ou privada. O petr?leo existente na camada pr?-sal, transforma um cen?rio de alt?ssimo risco em baixo risco, o que confere a Uni?o a possibilidade de determina??o de outra forma de explorar esses recursos de forma a fazer vale os interesses prim?rio da Administra??o P?blica

Abstract:
Abstract
Lion populations in West and Central Africa are small and
fragmented. In areas where park management is weak,
threats will likely facilitate the extinction of the lion.
Wildlife management requires knowledge of the population
estimate. The population of lions in Waza National
Park (Waza NP) was assessed by individual identification
of members in the population. The population was assessed
to comprise of 14–21 adult individual lions. The age
structure was skewed towards adults; cubs comprised 22%
of all lions identified while the sex ratio was 1 : 3. Two out
of four collared lions were lost to illegal, retaliatory killings
within 1 year; and probably two more males and one more
female were also killed during this period. The lion population
appears to have declined during the last 5 years
with six lions dying per year, which is at a much higher
rate than observed in the previous decades. Human-livestock
pressure has increased tremendously in this period,
resulting to frequent human-lion conflicts. To ensure the
survival of the lion in Waza NP and in the entire region,
management needs to intensify efforts to mitigate the
pressure from humans and their livestock.

Abstract:
During the eighties a new type of financial transaction started to emerge on an increasing basis. It was the so called “leveraged buyout” also known as the LBO. In the US private equity firms made it to the headlines in financial media from engaging in leveraged buyouts with small equity investments and large amounts of borrowed capital, their targets where large solid multinational corporations. Much has happened since the eighties. Back then leveraged buyouts where often associated with terms such as “Slash and Burn” or “Buy, Flip and Strip” often meaning hostile takeovers and huge layoffs. Today private equity firms focus more on active ownership, fast decisions without the bureaucracy of the stock market and long term value creation in order to profit from their buyouts.
As private equity firms today invest tremendous amounts of capital through their private equity funds. Leveraged buyouts have become one of the major areas within investment banking. Even though the LBO is a common transaction it is often hard to find models used for valuation of such a deal. Private equity funds and investment banks all have their own valuation models but these are regarded as strictly confidential and seldom revealed to the public. Therefore the creation and publication of an LBO valuation model should be of great interest for everyone aiming at a future career within private equity, corporate finance or investment banking.
This thesis derives a complete LBO valuation model including a framework for finding a suitable LBO target. The LBO valuation model is created in cooperation with the debt capital markets department at one of the leading investment banks in the Nordic region. The framework is based on a qualitative study conducted on seven of the most distinguished private equity firms active in Sweden. In order to show how the LBO valuation model and the framework works, both are applied on the retail company Björn Borg listed on NASDAQ OMX. To verify the accuracy of the framework, calculated return from the model is analyzed and compared to the indications given by the framework.

Abstract:
While remaining rooted in a comparison of some of the primary texts of the thinkers under scrutiny, my thesis also discusses several issues which arise in the mutual consideration of Heidegger and Strauss, specifically the questions of the ontological and political status of nature, the problem of ‘first philosophy,’ and the method by which to interpret philosophical texts, as well as a continuous analysis of Strauss’s appellation of ‘modern,’ as opposed to ‘ancient,’ and ‘religious,’ as opposed to ‘philosophical,’ to Heidegger’s thought. I first consider every moment in Strauss’s corpus where he discusses Heidegger’s thought. From this discussion, I identify four main lines of critique which may be extracted from Strauss’s writings on Heidegger. Then, I turn to Heidegger’s texts themselves in order to determine if Strauss’s critique indeed finds purchase there, addressing each of the lines of critique in turn. Finally, I consider Strauss and Heidegger in tandem, in light of the three questions identified above. I show that many of what Strauss determines to be Heidegger’s errors arose as a result of the way that Heidegger read ancient philosophical texts, and I suggest that Strauss’s approach, i.e., to consider the possible esoteric meaning of a text, in fact permits the reader to access an interpretation that is truer to the textual phenomena. This claim, however, is not intended to obscure the remarkable similarities between each thinker’s respective interpretive methods. I conclude that Strauss’s critique of Heidegger, vehement as it is, also indicates Strauss’s dependence on Heidegger’s thought for the inspiration of Strauss’s own philosophical project. The relation between Strauss and Heidegger, then, remains profoundly ambiguous.

Abstract:
International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, NevadaThe Low Earth Orbit Terminal (LEO-T) developed by AlliedSignal for NASA Wallops is a fully autonomous satellite tracking system which provides a reliable, high quality, satellite data collection and dissemination service. The procurement was initiated by NASA, in an effort to provide more tracking capacity with a decreasing budget. A large mission set of NASA satellites in the next decade will not require the performance of existing large aperture systems. NASA is planning to use the larger aperture antennas to only support those missions needing the higher performance. The remainder of the missions will be supported with the smaller LEO-Ts, which are smaller, significantly less expensive, and fully automated. The procurement is also an attempt at a first step towards fostering commercialization and privatization of small station acquisition and services. The system design features a modular architecture to simplify integration and to support affordable future expansion.

Abstract:
El presente proyecto de innovación se plantea, debido a que los estudiantes
del 2do grado del nivel primaria de la IE Cesar Vallejo, según los resultados de la
Evaluación Regional y la Evaluación Censal de Estudiantes, solo un 32 % de ellos
logra comprender textos escritos a nivel satisfactorio, mientras que un alarmante y
mayoritario 68 % no logra comprender de forma adecuada dichos textos, lo cual
repercute en el logro de aprendizaje. Estos resultados se debe a la carencia de
bibliotecas con textos adecuados y motivadores que despierten el interés y
promuevan la lectura por placer en los estudiantes, sin lograr el desarrollo de hábitos
lectores; así mismo la principal razón es que los docentes carecen de estrategias
adecuadas para promover la comprensión de textos en sus estudiantes, por el
contrario utilizan metodologías tradicionales basadas en la resolución memorística
de fichas de lectura, que no despiertan el interés de los estudiantes, lo cual se
evidencia en la escasa capacidad de comprender textos escritos diversos. Asimismo,
la implementación de este proyecto innovador permitirá fortalecer las capacidades
profesionales y didácticas de los docentes, con estrategias innovadoras y pertinentes
como: El recreo lector y el portafolio de lecturas favoritas, los cuales promoverán el
hábito lector y la aplicación de estrategias para lograr comprender textos a nivel
inferencial. Por otro lado, este proyecto será sostenible porque será insertado dentro
del Plan Anual de Trabajo (PAT) y otros documentos de gestión, debido a que la
escasa comprensión lectora en los estudiantes, es una problemática que afecta a
toda la institución educativa; como tal se considerará como un objetivo estratégico a
lograrse en el mediano y corto plazo; para ello se evaluará de forma periódica los
avances y dificultades a fin de realizar los reajustes necesarios y mejorar sus
resultados.Trabajo académico

Abstract:
L'autrichien Leo Perutz (1882-1957) a souvent été lu dans la perspective du fantastique, ce qui a suscité des réserves. Cette étude reprend la question théorique et analyse l'œuvre à partir d'une définition rénovée du genre. Le corpus n'étant pas encore pleinement reconnu, problème par ailleurs fréquent dans le fantastique allemand, un 1er chapitre étudie la réception de l'écrivain et propose une évaluation raisonnée de son œuvre. Le chapitre 2 examine les problèmes liés à la notion de fantastique en soulignant les différences d'approche entre les traditions critiques françaises et germaniques. Le genre est défini, dans une perspective pragmatique, comme une organisation contradictoire du matériel narratif entre écriture mimétique et emprunts au merveilleux, qui fait éclater la cohésion épistémologique et esthétique de la référence au réel, selon des enjeux propres à chaque auteur. Cette proposition est ensuite confrontée au corpus perutzien, selon un parcours linéaire. Les éléments concourant à l'effet de réel – art du détail, réalisme textuel et ancrage social – sont d'abord examinés au chapitre 3. La dimension spatio-temporelle et les difficultés d'interprétation liées à la mise en œuvre ambivalente des références historiques fournissent la matière du chapitre 4, le 5e portant sur la recomposition en partie imaginaire de l'histoire qui en fait paradoxalement apparaître certains enjeux fondamentaux : la question de la révolution et celle de l'empire allemand vu comme un espace chimérique. Le chapitre 6 aborde d'autre part les emprunts stylistiques et thématiques au domaine du merveilleux, entre ésotérisme dérisoire et surnaturel judéo-chrétien, et le chapitre 7 étudie les architectures paradoxales nées de cette double allégeance esthétique. Au cœur de constructions aporétiques mariant fatalité et conscience malheureuse se reflète un fantasme d'héroïsme qui, dangereusement manié par un nouveau Führer, deviendra aussi un leurre politiqueLeo Perutz (1882-1957) is regarded as a master in fantastic literature, a fact which has sometimes aroused reservations. This study sets the theoretical problem again and analyses Perutz's work on the basis of a revised definition of the genre. As the corpus has not been fully recognized yet – a problem which is common in German fantastic literature – the 1st chapter studies how these texts have been evaluated and offers a reasoned appraisal of them. The 2nd chapter explores the problems linked to the notion of fantastic literature, highlighting how different the German critical approach to this genre is compared to the French one. The genre is then defined in a pragmatic way, as a contradictory organization of the various elements in the narrative – a blend of mimetic writing and marvellous literature – which disrupts the epistemological and aesthetic cohesion of the references to reality, in ways specific to each author. This definition is then applied to LP's work. The various elements that contribute to recreate reality (the attention to details, textual realism, a close observation of social realities) are examined in chapter 3. Chapter 4 deals with space and time and with the difficulties one can have in interpreting the ambivalent historical references. The 5th chapter is about the partly imaginary reconstruction of history which, paradoxically enough, underlines some of its fundamental issues: the question of the Revolution, the German Empire seen as a chimerical territory. Chapter 6 deals with the stylistic and thematic borrowings from the marvellous, which result in a blend of mocked esotericism and Judeo-Christian supernatural. Chapter 7 explores the paradoxical architectures that such a twofold aesthetic allegiance generates. At the very heart of aporetic constructions uniting fatality with a kind of sad awareness, one can recognize characters fantasizing themselves as heroes: such fantasies, when manipulated by a Führer will lead to political delusion
