Abstract:
Memoria en Formato Audiovisual para optar al título de Periodista
Esta es una ventana a la vida de Francisco Tapia, alias “Papas Fritas”, un artista visual chileno autodidacta de 32 años. No estudió artes, no estudió técnica ni teoría, pero aún así ha logrado destacarse dentro del círculo artístico chileno. ¿Cómo? Con polémicas obras explícitas e impactantes que contienen una carga crítica muy potente del sistema en que vivimos. Entre ellas destaca su obra con mayor impacto mediático: Ad Augusta per Angusta (mayo, 2014), en la que se auto denunció como responsable de la quema de cientos de pagarés de estudiantes de la Universidad del Mar, valorados aproximadamente en 500 millones de dólares. Esta Universidad se había convertido en el ícono del lucro de la educación en Chile cuando se detectó una estafa millonaria a los estudiantes. A pesar de su explosivo y revolucionado arte, Papas Fritas debe enfrentarse constantemente a una condición que le impide desenvolverse íntegramente: la agorafobia. Esta enfermedad se ha manifestado luego de la muerte de su padre y le ha impedido salir de su casa durante los últimos seis años. Este proceso y su lucha contra la agorafobia, han sido documentados en esta obra audiovisual como una enfermedad generada por la resistencia, la rabia por un sistema que lo oprime y que termina por combatir desde su casa, con su arte, discursos y sus acciones.

Memoria para optar al Título Profesional de Médico Veterinario
El objetivo del presente estudio fue realizar una caracterización epidemiológica de las mordeduras de perro ocurridas el año 2012 en la Comuna de Quinta Normal. Además, se determinaron costos promedios de la atención de estos accidentes en los Servicios de Salud Pública. La información fue recopilada desde hospitales y consultorios de la Comuna. Detalles del animal y otros datos relativos a la agresión fueron obtenidos a través de una encuesta a los afectados. Las mordeduras fueron clasificadas en tres estratos según severidad de la lesión. De las 517 personas atendidas, 408 personas fueron mordidas por perros. No hubo asociación entre la raza del perro, procedencia del animal y lugar donde ocurrió la agresión con la gravedad de la lesión. Los costos alcanzados por tratamiento y por personal que realiza cada atención de una mordedura se estimó un promedio de $43.082 para mordeduras leves, $48.170 para mordeduras graves y $336.020 para mordeduras muy graves. En conclusión, la implementación de programas de educación en tenencia responsable, y una legislación apropiada al respecto, entre otras medidas, resultan acciones imperativas para lograr aminorar la magnitud de este problema.

Se brinda una visión de la problemática de la rabia de tipo urbano en el departamento Central, que es la predominante en esta región del país. Con este objetivo, son analizados los diagnósticos laboratoriales en base a una muestra aleatoria, y otra muestra de las fichas de atención a personas víctimas de agresiones producidas por animales en el departamento Central de Paraguay, entre los años 1992-1997. Es presentado además el número de casos de rabia humana entre 1992-1997, y algunas características del Programa de Control de la Rabia en el Paraguay. Del análisis de datos observamos a la especie canina como la responsable por el 85,2 por cento de las muestras analizadas en el laboratorio, por el 94,9 por cento de las agresioines, y en 1997 causaron el 100 por cento de los casos de rabia humana en el país. El grupo etáreo más afectado por las agresiones es el de hasta 10 años de edad. No existe diferencia significativa entre el número de víctimas de mordeduras, masculino o femenino. La cobertura de vacunación en el departamento, es muy baja, hecho este que facilita la aparición de casos sean humanos o caninos. La captura de animales callejeros no está siendo llevada a cabo en proporciones importantes como para pensar en el control de la enfermedad.

Abstract:
La malaltia de la ràbia és probablement una de les malalties més descuidades pels serveis sanitaris en aquells països on es classifica com a endèmica; no obstant això, els estudis realitzats al llarg de molts anys, que presentem en aquest document, mostren que la ràbia salvatge transmesa per ratpenats hematofàfags és més una malaltia emergent de curs lent que un enzoòtic per se. La importància de la ràbia rau no només en el fet que es tracta d’una malaltia mortal per als animals humans, domèstics i salvatges (de vida lliure), per a aquells de nosaltres que hem tingut l’oportunitat d’estudiar-la, la seva importància se centra en l’oportunitat que la ràbia proporciona per poder estudiar l’epidemiologia d’una manera integral. La ràbia és una malaltia zoonòtica que afecta diverses espècies, incloent-hi els humans, molts dels reservoris de la ràbia són animals salvatges, per tant, incorpora en el seu estudi moltes disciplines com la biologia, l’ecologia, la història natural, la genètica, la veterinària, la medicina, permetent integrar de manera transversal conceptes com nínxols ecològics, anàlisi filogenètica, epidemiologia molecular, teoria de la coalescència Etc. Els enfocaments de la salut dels ecosistemes, la salut compartida o un món de salut convergeixen d’una manera perfecta a l’hora de parlar de ràbia, perquè les seves forces de prevenció i control treballin amb una perspectiva integral i multidisciplinària. Analitzar els determinants socials que permeten l’aparició d’aquesta malaltia d’importància de la salut pública és una prioritat. La ràbia com a malaltia infecciosa és complexa en estat salvatge, i és impulsada en certa mesura pels canvis ecosistèutiques que s’associen amb el creixement de la població humana en zones de risc, l’augment de la demanda de proteïna animal i, per tant, l’augment de la cria d’animals domèstics, el consum insostenible de recursos naturals , la pèrdua de biodiversitat i la fragmentació de l’hàbitat són factors que es tradueixen en una disminució dels serveis ecosistènics, per tant la ràbia, ja que una malaltia emergent augmenta els riscos per a la salut de totes les espècies en un ecosistema, humans, animals domèstics i fauna salvatge. A més, a partir del canvi climàtic i de la pèrdua de resiliència ecosistèutic que són factors que obren el camí per a l’aparició de noves amenaces com la ràbia transmesa per ratpenats, afegeix la sinantropia dels ratpenats hematofàgens i els factors antropogènics que afavoreixen el seu desplaçament, contribueixen directament a l’aparició, augment i incidència de la ràbia al Perú. L’objectiu principal d’aquest estudi ha estat el desenvolupament d’una anàlisi epidemiològica exhaustiva i detallada de la ràbia salvatge, els resultats i les discussions que plantegem són inèdits, reveladors, però sobretot valuosos en la prevenció i control de la ràbia salvatge transmesa per ratpenats hematofàgics.
Probablemente la enfermedad de la rabia es una de las enfermedades más desatendidas por los servicios de salud en aquellos países donde la tienen categorizada como endémica; sin embargo, los estudios realizados por muchos años y los cuales plasmamos en este documento, evidencian que la rabia silvestre trasmitida por murciélagos hematófagos es más una enfermedad emergente de curso lento que una enzoótia per se. La importancia de la rabia no solo radica en el hecho que es una enfermedad mortal para humanos, los animales domésticos y silvestres (de vida libre), para aquellos que hemos tenido la oportunidad de estudiarla, su importancia se centra en la oportunidad que la rabia brinda para poder estudiar la epidemiología de manera integral. La rabia es una enfermedad zoonótica que afecta a un sin número de especies incluyendo el humano, muchos de los reservorios de la rabia son animales silvestres por tanto incorpora en su estudio a muchas disciplinas como la biología, ecología, historia natural, genética, veterinaria, medicina, permitiendo integrar de manera transversal los conceptos como nichos ecológicos, análisis filogenéticos, epidemiología molecular, teoría de la coalescencia, etc. Los enfoques de salud ecosistémica, salud compartida o un mundo una salud convergen de una manera perfecta si se habla de la rabia, para su prevención y control obliga a trabajar con una perspectiva integral y multidisciplinaria. Analizar los determinantes sociales que permiten la emergencia de esta enfermedad de importancia para la salud pública, es prioritario. La rabia como enfermedad infecciosa es compleja en el medio natural, y se ve impulsada hasta cierto punto por cambios ecosistémicos que se asocian con el crecimiento de la población humana en las zonas de riesgo, el aumento de la demanda de proteína animal y por ende el aumento de la crianza de animales domésticos, el consumo insostenible de los recursos naturales, la pérdida de biodiversidad y la fragmentación del hábitat son factores que se traducen en una disminución de servicios ecosistémicos, de esta manera, la rabia, como enfermedad emergente aumenta los riesgos para la salud de todas las especies de un ecosistema, los seres humanos, los animales domésticos y la fauna silvestres. Además, del cambio climático y la perdida de resiliencia ecosistémica que son factores que preparan el terreno para la irrupción de nuevas amenazas como la rabia trasmitida por murciélagos, se suma la sinantropía de los murciélagos hematófagos y los factores antropogénicos que favorecen su desplazamiento, contribuyen directamente en la emergencia, incremento e incidencia de la rabia en el Perú. El objetivo principal de este estudio ha sido el desarrollo de un análisis epidemiológico minucioso y detallado de la rabia silvestre, los resultados y discusiones que planteamos son inéditos, reveladores, pero sobre todo valioso en la prevención y control de la rabia silvestre trasmitida por murciélagos hematófagos.
Rabies is probably one of the most neglected diseases by health services in those countries where it is categorized as endemic; however, studies conducted for many years and which we present in this document, show that wild rabies transmitted by vampire bats is more of a slow emerging disease than an endemic disease per se. The importance of rabies lies not only in the fact that it is a deadly disease for humans, domestic and wild animals (free-living), but for those of us who have had the opportunity to study it, its importance lies in the opportunity that rabies provides to be able to study epidemiology comprehensively. Rabies is a zoonotic disease that affects several species including humans, many of the reservoirs of rabies are wild animals therefore incorporates into its study many disciplines such as biology, ecology, natural history, genetics, veterinary medicine, allowing to integrate into cross-sectional manner concepts such as ecological niches, phylogenetic analysis, molecular epidemiology, the theory of coalescence, etc. The approaches of ecosystem health, shared health or one world one health converge in a perfect way if we talk about rabies, for its prevention and control requires working with a comprehensive and multidisciplinary perspective. Analyzing the social determinants that allow the emergence of this disease of public health importance is a priority. Rabies as an infectious disease is complex in the natural environment, and is driven to some extent by ecosystem changes associated with human population growth in risk areas, increased demand for animal protein and thus increased breeding of domestic animals, and unsustainable consumption of natural resources, biodiversity loss, and habitat fragmentation are factors that result in a decline in ecosystem services, thus rabies as an emerging disease increases the health risks for all species in an ecosystem, humans, domestic animals, and wildlife. Besides, climate change and the loss of ecosystem resilience, which are factors that pave the way for the emergence of new threats such as bat-borne rabies, are compounded by the synanthropy of hematophagous bats and the anthropogenic factors that favor their displacement, directly contributing to the emergence, increase, and incidence of rabies in Peru.

El siguiente trabajo de investigación está centrado en el análisis comparado entre Rabia, la novela de Sergio Bizzio, y Rabia, la película dirigida por Sebastián Cordero. La comparación tiene como sustento las voluntades estéticas y de sentidos contempladas en ambas obras a partir de las diferencias, ya sean grandes o sutiles. El primer capítulo, aborda el tema del espacio, muy importante en ambas obras y coincidente en muchos aspectos. Se tratará el espacio desde sus características en general, entre otras cosas en su diferencia con el lugar, también los distintos tipos de espacios presentes en la historia (calle, supermercado, motel, mansión, etc.) y el significado implicado en cada caso y, por último, la casa, como el lugar más significativo de Rabia, en sus diversos aspectos. Junto con el espacio, la condición de inmigrante de los protagonistas forma parte de los elementos más relevantes de las obras. El segundo capítulo abordará el fenómeno de la migración en general, qué lo motiva, cómo se construye desde el pensamiento hasta el hecho, etc., así como se analizará la condición del inmigrante dentro de la sociedad ajena en la que se inserta, viviendo dentro, pero a la vez al margen, y la relevancia de esta situación de sujeto en Rabia, como propulsor de hechos. Por último, el tercer capítulo, tomará parte de los dos capítulos anteriores para dar forma a los sentidos que otorgan Bizzio y Cordero sobre la estadía del protagonista en la mansión. Veremos que el énfasis es puesto en distintos puntos y que la construcción del sujeto es diferente. Para una misma historia tendremos dos realizaciones y, por lo tanto, dos significancias.

Abstract:
Linfócitos T CD8 e células NK atuam no combate à infecções por bactérias intracelulares, vírus e células tumorais, provocando a morte dessas células por meio da secreção de grânulos citotóxicos. Proteínas RAB GTPase têm se destacado em estudos de tráfego intracelular, porém, são escassos dados sobre o papel destas proteínas em células citóxicas. Um estudo prospectivo de proteômica realizado por nosso grupo identificou a RAB2A, RAB5A, RAB17 e RAB18 em grânulos citotóxicos. Análises mais aprofundadas revelaram que a RAB2A está associada a proteínas como LAMP-1 e LAMP-2, enquanto que RAB5A, RAB17 e RAB18 estavam presentes na mesma linhagem em um contexto não contemplado neste estudo. Desenvolvemos ainda uma abordagem de silenciamento gênico da RAB2A, e por fim, adaptamos uma série de protocolos de simples execução e baixo custo para avaliar funções efetoras de células NK. O conhecimento da maquinaria secretória é fundamental, uma vez que defeitos nas vias de tráfego intracelular constituem a base de um grande número de doenças que desencadeiam quadros fatais.
CD8 T lymphocytes and NK cells fight against infections by intracellular bacteria, viruses and tumor cells by killing those cells through the secretion of cytotoxic granules. RAB GTPase has been highlighted in studies of intracellular trafficking, however there are scarce reports regarding the role of these proteins in cytotoxic cells. A proteomic study performed by our group identified RAB2A, RAB5A, RAB17 and RAB18 in cytotoxic granules. Further analysis revealed that RAB2A is associated with LAMP-1 and LAMP-2, while RAB5A, RAB17 and RAB18 were present in the same cell line, but in a context not included in this study. We also have developed a gene silencing approach for RAB2A and adapted a number of protocols, simple and low-cost, that can be used to evaluate effector functions of natural killer cells The knowledge of secretory machinery involved in the movement cytotoxic granules of cytotoxic cells is critical, since defects in intracellular trafficking pathways constitute the basis for a large number of diseases which trigger death.

De acuerdo a la tabla 1 se clasificaron los resultados en: negativo o positivos considerando el grado: 1+,2+,3+ y 4+. Se tomaron micrografías de las muestras que se observan en la tabla 2. Los resultados muestran que solo hasta el 3er día se encontró intensidad débil en la fluorescencia y poca presencia de antígeno en 2 de las 3 muestras analizadas, por lo que le corresponde una clasificación de 1+. En términos generales, la intensidad y cantidad de antígeno fue directamente proporcional al incremento del tiempo del sacrificio del ratón siendo en el 5to día cuando se observó una infiltración masiva de inclusiones en toda la muestra con una alta intensidad de fluorescencia, características que corresponden a un positivo 4+.
La rabia es una enfermedad que existe desde hace millones de años, afecta a mamíferos y es causada por un Lyssavirus de la familia Rhabdoviridae que provoca encefalitis aguda. No existe un tratamiento médico para la enfermedad por lo tanto una vez que aparecen los síntomas es mortal sin embargo se puede prevenir mediante la vacunación. Aunque gracias a las medidas de prevención y vacunación la rabia transmitida por perro se ha logrado controlar, en México, la rabia transmitida por animales silvestres es la principal preocupación ya que causa pérdidas económicas de millones de dólares principalmente en la industria ganadera y al sector salud por el diagnóstico, investigación de mordeduras de animales, tratamientos, indemnizaciones por pérdida de ganado, cuarentenas, vacunas, mantenimiento de los laboratorios de diagnóstico y programas de control animal.

Abstract:
Caracteriza la dinámica de la población canina con dueño durante un brote de rabia en Arequipa y evaluar su impacto en el resultado de las actividades del control de rabia. Específicamente, se compararon los parámetros poblacionales (natalidad, mortalidad, inmigración y emigración) entre dos zonas características de las ciudades en crecimiento: el urbano y periurbano. Se realizaron dos encuestas anuales puerta por puerta en localidades urbanas y periurbanas del distrito de Alto Selva Alegre (Arequipa) los años 2016 y 2017. La primera fue llevada a cabo en 41 localidades urbanas y periurbanas (6,240 viviendas) y en la segunda encuesta se seleccionó una submuestra de las localidades anteriores (3,000 viviendas). Mas del 50% de casas habitables fueron encuestadas en ambos años. El ratio de humano a perro varió de 2.65:1 a 2.49:1 para el área periurbana, y de 3.53:1 a 3.36:1 en el área urbana. Al menos 73% de las casas encuestadas tenía un perro. Las hembras representaron el 30% de la población canina en el área periurbana y 37% en el área urbana. Comparando los resultados del 2016 con el 2017, las coberturas de vacunación variaron de 57.5% a 68.3% en periurbano (p=0.004) y de 48.8% a 60.4% en urbano (p<0.001). La tasa de natalidad en urbano fue 46.2% y en el periurbano fue 41.0%; la tasa de mortalidad en urbano fue 31.0% y en periurbano 17.9%; la tasa de inmigración en urbano fue 8.9% y en periurbano fue 13.2%; y la tasa de emigración en urbano fue 2.5% y en periurbano 4.3%. Este estudio muestra una marcada diferencia entre el área periurbana y el área urbana con relación a la dinámica poblacional de perros con dueño. El crecimiento poblacional fue 7.5% en urbano y 8.5% en periurbano, y el recambio poblacional fue 34% en urbano y 48% en periurbano. La literatura indica que lograr una cobertura de vacunación del 70% durante las campañas masivas de vacunación de perros realizadas cada 12 meses sería suficiente para mantener la cobertura por encima del umbral crítico del 40-50%. Sin embargo, este estudio demuestra que la población de estudio es una población altamente dinámica, sobre todo en las zonas periurbanas. Este dinamismo puede afectar la inmunidad de hato y contrarrestar los esfuerzos realizados mediante las campañas de vacunación. Es deseable “estabilizar” a la población canina mediante disminución de la mortalidad y la natalidad para evitar una fuerte influencia de la dinámica poblacional sobre la inmunidad de hato y la cobertura vacunal efectiva.

Describe una propuesta de mejora en el proceso de envasado y sellado de la vacuna antirrábica veterinaria en una empresa estatal de rubro farmacéutico, encargada de producir manualmente diversos productos biológicos destinados para la salud pública, de consumo humano y veterinario, con el objetivo de proporcionar un producto de buena calidad y cumplir con el requerimiento de la demanda, el cual año tras año se ha ido incrementando. Al ser un procedimiento manual, existe un alto porcentaje de productos defectuosos, y a su vez un alto nivel de desgaste físico en los operarios debido a que deben permanecer por más de 5 horas seguidas en una misma posición. Adicionalmente, para llevar a cabo el proceso de envasado y sellado se requiere suspender las demás actividades del laboratorio, ya que en los días que se realiza dicho proceso se utiliza el 90% del personal, los cuales se distribuyen en el envasado, sellado y empacado de la vacuna. Es por ello que se plantea la adquisición de un sistema automatizado de envasado y sellado de vacunas, con el fin de incrementar la productividad, reducir tiempos operativos, mercadería defectuosa y evitar el riesgo de contaminación cruzada debido a la manipulación constante del producto.

Abstract:
Dans son premier chapitre, cette étude présente la poétique chez les penseurs, poètes et critiques confondus, dans le patrimoine arabe traditionnel jusqu’au XIVe siècle en en faisant la synthèse. Son deuxième chapitre expose le soufisme dans ses grandes lignes et dans ce qui le distingue en tant qu’approche existentielle de l’ensemble de la vision islamique. Ces mêmes caractéristiques se reflètent dans le troisième chapitre à travers la production poétique de trois de ses plus célèbres représentants à savoir Râbia Al- Adawiyya (m. 725), Umar Ibn Al-Fâridh (m.1235) et Mohyî Al-Dîn Ibn Arabî (m.1240). L’analyse de leurs œuvres respectives démontre que Râbia dans sa quête de purification, Ibn Al-Fâridh dans sa recherche à propager sa foi soufie à travers sa Tâiyya Al-Kubrâ (La Grande Tâiyya), et Ibn Arabî avec son dessein de réfuter tout écrit stable et rigide dans son recueil Turjumân Al-Achwâq (l’Interprète des désirs), ont eu trois approches différentes de la création poétique. Râbia l’utilise comme catharsis. Ibn Al-Fâridh, en s’adressant essentiellement à son lecteur, essaye de l’imprégner de sa propre foi soufie, alors qu’Ibn Arabî cherche à instaurer « un Texte » idéal. Aussi conclut‑on que ces poètes soufis ont eu trois approches différentes de la création poétique. L’analyse de leurs œuvres respectives démontre qu’« émetteur », « récepteur » et « message » sont les trois pôles d’intérêts de ces poètes. Dans le quatrième chapitre de cette étude, trois œuvres poétiques de trois poètes contemporains sont analysées afin de déceler les filigranes soufis de leurs poèmes. Il s’agit de « Al-Tûfân Al-Aswad » (Le déluge noir) de Muhammad Miftâh Al-Faytûrî (1936-…), d’Al-Kibrît wa Al-Asâbi (l’Allumette et les doigts) de Nizâr Qabbânî (1923-1998), et de Qaṣîdat Al-Takwîn (le poème de la genèse) d’Adonis (1930-…). Ainsi cette analyse prouve-t-elle l’influence du soufisme dans la pratique de la création poétique arabe. Quant au cinquième chapitre, il démontre cet héritage soufi dans les théories poétiques arabes contemporaines et son influence dans l’instauration de trois approches poétiques différentes constituant ce que l’on appellerait « l’école purificatrice », « l’école imprégnatrice » et « l’école de la réfutation» ; ces théories ne tenant nullement compte du corpus littéraire exposé dans le premier chapitre. Outre la traduction de Claudine Chonez de « la Grande Tâiyya », les poèmes analysés sont cités en annexe à la fin de cette étude avec une traduction personnelle, qui bien qu’elle ne prétende nullement refléter la profondeur et la beauté des poèmes arabes, ne désespère pas pour autant de la laisser entrevoir
The first chapter in this study presents the poetic thinkers, poets and critics alike, in the traditional Arabic heritage until the fourteenth century by making a synthesis. The second chapter presents Sufism in outline and in what distinguishes it as an existential approach throughout the Islamic view. These same characteristics are reflected in the third chapter through the poetic production of three of its most famous representatives namely Rabia Al-Adawiyya (d. 725), Umar Ibn Al-Fâridh (d. 1235) and Mohyî Al -Dîn Ibn Arabi (d. 1240). The analysis shows that in their respective works, they also had three different approaches to poetic creation. Rabia with her quest for purification uses it as a catharsis, Ibn Al-Fâridh, with his quest to spread his Sufi faith through his Al-Tâiyya Kubrâ (The Great Tâiyya),tries to impregnate his own Sufi liver faith, and Ibn Arabi, with his plan to refute any writing stable and rigid trough his collection of poems Turjumân Al-Achwaq (the interpreter of desires), seeks to establish an ideal "Text ".Thus we can conclude that these Sufi poets had three different approaches to poetic creation. The analysis of their respective writings demonstrates that "issuer", "receiver" and "message" are the three core interests of these three Sufi poets. In the fourth chapter of this study, three poetic works of three contemporary poets are analyzed to detect the Sufi watermarks of these poems. It is Al-Tufan Al-Aswad (The Black Flood) of Muhammad Miftâh Al-Faytûrî (1936 - ...), Al-Kibrît wa Al-Asâbi (The Match and the Fingers) of Nizar Qabbâni (1923-1998), and Qasîdat Al-Takwîn The Poem of the Genesis of Adonis (1930 - ...). Their analysis proves the influence of Sufism in the practice of the creation of Arabic poetry. The fifth chapter demonstrates this Sufi legacy in poetic theories in contemporary Arab thought and its influence in the establishment of three different poetic approaches constituting the so-called " the Purifying School," " the Impregnator School" and "the Refutation School", these theories take no account of the literary corpus described in the first chapter. Besides the translation of Claudine Chonez of "Great Tâiyya," the poems are cited in Appendix at the end of the study with a personal translation, which, although it does not claim to reflect in any way the depth and beauty of Arabic poems, she does not despair for the many suggest

Abstract:
Nel 1936, nel corso della primavera della meccanica quantistica, Isidor Isaac Rabi investigò la versione semiclassica di un modello che adesso porta il suo nome. Il modello di Rabi descrive la più semplice interazione tra un atomo a due livelli e un'onda elettromagnetica monocromatica. A lungo, si è pensato che il modello quantistico di Rabi, in cui anche il campo è quantizzato, non avesse soluzioni esatte e pertanto gli è stato preferito una versione approssimata e valida solo a determinate condizioni, il modello Jaynes-Cummings. Questo modello ha il vantaggio di essere più facilmente risolubile e in più le condizioni di applicabilità sono comunque verificate nella maggior parte dei regimi sperimentali. Nel 2011, tuttavia, è stata presentata una soluzione analitica al problema di Rabi, dimostrando così che il modello quantistico di Rabi è risolvibile esattamente. In questa tesi, si introduce inizialmente l'hamiltoniana di Rabi che descrive il sistema, studiando separatamente i tre termini che la compongono: l'hamiltoniana atomica, l'hamiltoniana del campo e l'hamiltoniana di interazione. Si presentano successivamente tre approcci risolutivi del problema: la soluzione attraverso la trasformazione di Bogoliubov, la soluzione nello spazio di Bargmann-Fock e la soluzione in termini di funzioni confluenti di Heun. Infine si propongono tre generalizzazioni del modello tra le tante studiate negli ultimi anni: il modello di Rabi a due fotoni, il modello di Rabi anisotropo e il modello di Rabi asimmetrico.

Abstract:
Esta tesis estudia fases geométricas que aparecen cuando un átomo de dos niveles interacciona con un campo electromagnético monomodal cuantizado, un modelo descrito por el Hamiltoniano de Rabi (HR). Como se conoce, el HR no tiene una solución cerrada; no obstante, cuando el acoplamiento entre el átomo y campo es débil, la aproximación de onda rotante (RWA) puede ser aplicada. Esto resulta en el Hamiltoniano de Jaynes-Cummings (HJC), el cual es una útil solución analítica aproximada del primero. Cuando la RWA puede ser aplicada, fenómenos físicos predichos en el modelo de Rabi deben también aparecer en el modelo de Jaynes-Cummings; caso contario, la aproximación será físicamente inconsistente. Esto último generó una controversia después de una reciente afirmación sobre fases de Berry en el HR. De acuerdo a ésta, la RWA no es válida para ningún valor del acoplamiento entre el átomo y campo. Los resultados de esta investigación, cálculos numéricos de la fase de Berry en el HR, muestran que este no es el caso y que afirmaciones contrarias son inconsistentes con un argumento analítico que concierne al modelo de Rabi. Adicionalmente, se muestra que estos resultados convergen a los respectivos para el HJC, concluyendo as__ que la RWA es consistente al aplicarse a fases de Berry, como era de esperarse. Finalmente, se discute que la aparición de fases de Berry no depende de la condición adiabática; por lo tanto, el marco de estudio apropiado es el cinemático, el cual contiene a la fase de Berry como un caso particular de la fase geométrica. También se discute que el Hamiltoniano no desempeña un rol importante, salvo de proveedor de los autovectores usados en el cálculo de la fase geométrica. Esto manifiesta la característica esencial de la cual depende la fase geométrica, que es la geometría del espacio de rayos. Este espacio depende de los tipos de evolución que sean considerados. Este punto es ilustrado estudiando una diferente transformación unitaria en el modelo de Schwinger.

Abstract:
Psychobiographies use psychological theory as a paradigm within which to re-awaken an individual’s life story. The psychobiographical approach historically tended to be neglected within the South African context. The aim of the current study was to explore and describe the life of Ralph John Rabie through the use of psychobiography. Ralph John Rabie (1960 – 2002) was a South African Afrikaans singer-songwriter, journalist and playwright, also known as Johannes Kerkorrel. He challenged the cultural system and the government and was arguably the most prominent member of the Alternative Afrikaans Movement until his suicide on 12 November 2002. To some he betrayed the identity of post-apartheid Afrikanerdom and to others he became an icon in the homosexual community. No existing literature to date has adopted a psychological stance on this controversial South African figure. His own writings and published material by others were utilized to illuminate his life and its many dimensions. Richard C. Schwartz’s Internal Family Systems Model (1995) was used to analyze the multiplicity and inner workings of Rabie’s personality. The influence of external systems is also discussed. The data collection and analysis were conducted according to Yin’s (1994) analytic generalization, which consists of using theoretical guidelines as a framework to select relevant data and develop a matrix as a descriptive framework for organizing and integrating the data. Alexander’s (1988) nine proposed guidelines assisted in the process of data analysis, together with the Internal Family Systems Model (1995). The findings of the study indicate that subpersonalities in different roles could be identified in Rabie’s life as described by Schwartz (1995). The different subpersonalities interacted with each other and assumed roles to protect Rabie. The findings of the study also indicated that these subpersonalities used stories to obtain power and influence within Rabie’s personality structure. The subpersonalities were successful in making Rabie influential and famous within the Afrikaans music industry and they helped Rabie change rigid Afrikaans cultural beliefs that were present within the Apartheid system. The findings further indicate how important it is for subpersonalities to work together and how a fragmented system is difficult to contain.

Raia Divisória ou Raia Socioambiental? é um questionamento que se deu a partir da minha inquietação sobre a definição conceitual da zona de contato constituída pelos territórios do extremo Sudoeste paulista, Noroeste paranaense e Sudeste sul-mato-grossense.

No Sudoeste paulista, foi motivada pelo avanço do café e da ferrovia; apropriação ilegal de reservas florestais e desmatamentos agressivos. O Noroeste paranaense, por sua vez, foi contemplado com uma concepção moderna de colonização, cujo parcelamento dos lotes rurais foi realizado para dinamizar a economia. No Sudeste sul-mato-grossense houve a extensão da capitalização observada nas áreas próximas e de ocupação anterior.

Abstract:
Dans son premier chapitre, cette étude présente la poétique chez les penseurs, poètes et critiques confondus, dans le patrimoine arabe traditionnel jusqu'au XIVe siècle en en faisant la synthèse. Son deuxième chapitre expose le soufisme dans ses grandes lignes et dans ce qui le distingue en tant qu'approche existentielle de l'ensemble de la vision islamique. Ces mêmes caractéristiques se reflètent dans le troisième chapitre à travers la production poétique de trois de ses plus célèbres représentants à savoir Râbia Al- Adawiyya (m. 725), Umar Ibn Al-Fâridh (m.1235) et Mohyî Al-Dîn Ibn Arabî (m.1240). L'analyse de leurs œuvres respectives démontre que Râbia dans sa quête de purification, Ibn Al-Fâridh dans sa recherche à propager sa foi soufie à travers sa Tâiyya Al-Kubrâ (La Grande Tâiyya), et Ibn Arabî avec son dessein de réfuter tout écrit stable et rigide dans son recueil Turjumân Al-Achwâq (l'Interprète des désirs), ont eu trois approches différentes de la création poétique. Râbia l'utilise comme catharsis. Ibn Al-Fâridh, en s'adressant essentiellement à son lecteur, essaye de l'imprégner de sa propre foi soufie, alors qu'Ibn Arabî cherche à instaurer " un Texte " idéal. Aussi conclut‑on que ces poètes soufis ont eu trois approches différentes de la création poétique. L'analyse de leurs œuvres respectives démontre qu'" émetteur ", " récepteur " et " message " sont les trois pôles d'intérêts de ces poètes. Dans le quatrième chapitre de cette étude, trois œuvres poétiques de trois poètes contemporains sont analysées afin de déceler les filigranes soufis de leurs poèmes. Il s'agit de " Al-Tûfân Al-Aswad " (Le déluge noir) de Muhammad Miftâh Al-Faytûrî (1936-...), d'Al-Kibrît wa Al-Asâbi (l'Allumette et les doigts) de Nizâr Qabbânî (1923-1998), et de Qaṣîdat Al-Takwîn (le poème de la genèse) d'Adonis (1930-...). Ainsi cette analyse prouve-t-elle l'influence du soufisme dans la pratique de la création poétique arabe. Quant au cinquième chapitre, il démontre cet héritage soufi dans les théories poétiques arabes contemporaines et son influence dans l'instauration de trois approches poétiques différentes constituant ce que l'on appellerait " l'école purificatrice ", " l'école imprégnatrice " et " l'école de la réfutation" ; ces théories ne tenant nullement compte du corpus littéraire exposé dans le premier chapitre. Outre la traduction de Claudine Chonez de " la Grande Tâiyya ", les poèmes analysés sont cités en annexe à la fin de cette étude avec une traduction personnelle, qui bien qu'elle ne prétende nullement refléter la profondeur et la beauté des poèmes arabes, ne désespère pas pour autant de la laisser entrevoir.

Abstract:
The current studies assessed the role of trait anger and anger expression styles on risk decision-making in adulthood, adolescence and childhood. In the first experiment 158 adults completed the STAXI-2 and an inventory consisting of a battery of hypothetical everyday decision-making scenarios. Participants were also asked to evaluate the perception of risk for each chosen option and some contextual characteristics, that are familiarity and salience for each scenario. The study provides evidence for a relationship between individual differences in the tendency to feel and express anger and risky decisions and for mediation effects of familiarity and salience appraisals. Moreover, results indicated that trait anger was predictive of risk perception and they provide evidence for a positive relationship between risk decision-making and risk perception. In the second study, we examined the relationship between specific components of anger (i.e., cognitive, affective and behavioural) and risk decision-making in adolescents. 101 subjects completed specific tasks, measuring risk decision-making, assessed using hypothetical choice scenarios, and anger, evaluated through the STAXI-CA and the MSAI-R. Results showed that adolescents higher on hostility, anger experience and destructive expression, make more risky decisions in everyday life situations. Moreover, regression analyses indicated that destructive expression of anger and hostility were predictive of adolescents’ risky decisions. In the third experiment, 104 children completed three tasks: the STAXI-CA, the MSAI-R and a task measuring risk decision-making in everyday situations. Subjects were also asked to evaluate the degree of danger, benefit, fun and fear perceived for each risky choice. Analyses indicated that: (a) risk decision-making was predicted by both trait anger and outward expression of anger; (b) destructive expression o anger was predictive of children’s risky decisions; (c) appraisal of danger fully mediated the relation between trait anger and risk; (d) perceptions of benefit, scare and fun partially mediated the relationship between trait anger and risk; and (e) appraisal of danger partially mediated the relationship between outward expression of anger and risk decision-making. The results provide evidence for a relationship between dispositional anger and risk decision-making during childhood, suggesting a possible explanation of the mechanisms below. In particular, risk decision-making can be viewed as the output of cognitive and emotive processes, linked to dispositional anger that leads children to be amused, optimistic and fearless in potentially risky situations. These findings substantiate the importance of incorporating cognitive and emotive factors in theories that seek to explain the relationship between personality traits and risk decision making across a broad range of age.

Full text
Abstract:
Les nanotubes de tunnellisation (TNT) sont des structures riches en F-actine qui relient des cellules distantes, permettant le transport de nombreux composants cellulaires (des vésicules, des organites etc.). Les TNT sont impliqués dans des processus cellulaires clés, tels que le développement, l'immunité et la régénération des tissus, mais également dans la transmission de divers agents pathogènes. Plusieurs facteurs moléculaires ont été identifiés pour participer à la formation de la formation de TNT. Le complexe de l'exocyste est l'un des premiers facteurs moléculaires impliqués dans cette formation. Il est impliqué dans l’attachement des vésicules sécrétoires, suggère que les protéines qui régulent le trafic vésiculaire pourraient jouer un rôle dans la formation de TNT. Nous avons émis l'hypothèse que la formation de TNT est modulée par des protéines qui participent à la fois à la régulation du trafic vésiculaire et au remodelage du cytosquelette d'actine, deux processus qui sont essentiels pour la formation de ces structures. Comme les Rab-GTPase sont les principaux régulateurs du trafic vésiculaire et participent à la régulation du cytosquelette d'actine, nous avons examiné le rôle de cette famille de protéines dans la formation de TNT. Tout d'abord, nous avons effectué un criblage de plusieurs protéines de Rab pour son effet sur le transfert de vésicule dépendant de TNT. Nous avons constaté que Rab8a, Rab11a et Rab35 ont un effet positif sur le transfert de vésicule. Surexpression de Rab8a et Rab11a augmentait également le nombre de cellules connectées au TNT. Lors de la surexpression de VAMP3 (une autre protéine impliquée dans le trafic vésiculaire), augmentait du nombre de cellules connectées au TNT. Une analyse plus poussée a montré que les trois protéines (Rab11a, Rab8a et VAMP3), ont un effet sur la formation de TNT de manière cascade. Pour établir une relation entre Rab11a et Rab8a, nous avons vérifié le rôle de Rabin8 sur la formation de TNT (une protéine qui interagit avec Rab11 et qui active Rab8) et nous n’avons observé aucun effet dans la formation de TNT. De plus, nous avons vérifié une autre protéine dont la fonction est similaire à Rabin8, à savoir GRAB (facteur d’échange de nucléotide de guanine-GAP- pour Rab3A) et son rôle dans la formation de TNT. Surexpression de GRAB augmente la formation de TNT, mais qu’elle agit de manière indépendante de Rab11 et Rab8a pour réguler la formation de TNT. L'analyse de Rab35-GTP, impliquée dans le recyclage des endocytes, la cytokinèse et la croissance des neurites, augmente la formation de TNT. La croissance des neurites est nécessaire pour la connectivité neuronale et le recyclage des vésicules joue un rôle crucial dans ce processus. Rab35 interagit avec plusieurs protéines impliquées dans le trafic vésiculaire, telles que ACAP2 (GAP de ARF6), MICAL-L1 (molécule interagissant avec CasL-like1 et participe dans le recyclage des vésicules) EHD1 (un ciseau moléculaire) qui participe dans la scission de la vésicule). Sur les endosomes positifs pour ARF6, Rab35 recrute ACAP2 et MICAL-L1 et forme un complexe qui se lie à EHD1 pour réguler la croissance des neurites. Nos données suggèrent fortement que ces effecteurs pourraient également être impliqués dans la formation de TNT. Individuellement, ACAP2, EHD1 et ARF6-GDP régulent la formation de TNT de manière positive et MICAL-L1 ne montre aucun effet sur les TNT. En outre, des données préliminaires indiquent que Rab35 et EHD1 agissent dans un mécanisme en cascade pour réguler la formation de TNT, suggérant que la formation de TNT et la croissance des neurites peuvent agir de manière similaire. Les molécules identifiées constituent des cibles moléculaires potentielles pour les thérapies visant à bloquer la propagation d'agents pathogènes transférés à travers les TNT. Cette étude prouve que les protéines jouant un rôle dans le trafic vésiculaire et la croissance des neurites participent également à la formation de TNT
Tunneling nanotubes (TNTs) are F-actin rich structures that connect distant cells, allowing the transport of many cellular components, including vesicles, organelles and different kind of molecules. TNTs are implicated in key cellular processes, such as development, immunity and tissue regeneration, but also in the transmission of various pathogens. Several molecular factors have been identified to participate in the regulation of TNT formation. One of the early molecular factors that is implicated in TNT formation is the exocyst complex. This complex is also involved in the tethering of secretory vesicles during secretion, which suggest that proteins that regulate vesicle trafficking could have a role in TNT formation. We have hypothesized that the formation of TNTs is modulated by proteins that participate in both, the regulation of vesicle trafficking and the remodelling of the actin cytoskeleton, and that these two processes are key for the formation of these structures. Since Rab GTPases are the major regulators of vesicle trafficking and also participate in actin cytoskeleton regulation, we examined the role of this protein family in TNT formation. First, we performed a screening of several different Rab proteins for its effect on TNT-dependent vesicle transfer. We found that Rab8a, Rab11a and Rab35 have a positive effect on vesicle transfer. Additional studies demonstrated that Rab8a and Rab11a overexpression also increase the number of TNT connected cells. Upon overexpression of VAMP3 (another protein involved in vesicle trafficking), we also observed an increase in the number of TNT connected cells. Further analysis showed that all three proteins, i.e. Rab11a, Rab8a and VAMP3, show an effect on TNT formation in a cascade dependent manner. To establish a relationship between Rab11a and Rab8a, we checked the role of Rabin8 (a protein that interacts with Rab11 and activates Rab8), on TNT formation and we found that it has no role in TNT formation. Additionally, we checked another protein whose function is similar to Rabin8, i.e. GRAB (guanine nucleotide exchange factor for Rab3A) and its role in TNT formation. The results show that GRAB overexpression increases TNT formation, but it acts in a pathway independent of Rab11 and Rab8a to regulate TNT formation. The analysis of Rab35, a protein involved in endocytic recycling, cytokinesis and neurite outgrowth, showed that the GTP-Rab35 bound form also increases TNT formation. Neurite outgrowth is an essential process in order to establish neural connectivity and vesicle recycling plays a crucial role in this process. Rab35 interacts with several proteins, that are involved in vesicle trafficking such as such as ACAP2 (acts as GAP of ARF6), MICAL-L1 (molecule interacting with CasL-like 1, which plays a role in vesicle recycling) EHD1 (a molecular scissor that has a role in vesicle scission). At the ARF6 positive endosomes, Rab35 recruits ACAP2 and MICAL-L1, and forms a complex that binds to EHD1 to regulate neurite outgrowth.Our data strongly suggest that these effectors may also be involved in the formation of TNTs. Individually, ACAP2, EHD1 and ARF6-GDP regulate TNT formation in a positive manner. But MICAL-L1 overexpression in cells shows no effect on TNTs. Also, preliminary data, indicates that Rab35 and EHD1 acts in a cascade mechanism to regulate TNT formation. This indicates that TNT formation and neurite outgrowth may act in a similar, but not exact pathway. The molecules identified here that have a role in TNT formation, constitute potential molecular targets for therapies aiming to block the spreading of pathogens that transfer through TNTs.This study proves that proteins that have a role in vesicle trafficking and neurite outgrowth, such as Rab proteins, are also involved in TNT formation

The Rabi model is the most complete one has to describe the interaction between radiation and matter. However, as it is difficult to obtain the exact solution to this model, many of recent atom-field studies have used the Jaynes-Cummings model, which eliminates the "counter rotating" terms from the Rabi Hamiltonian in an approach known as "rotating wave approximation". This approach was very precise to describe many experiments in quantum optics area in the past two decades, especially in the context of cavity quantum electrodynamics, where the atom-field coupling g is very weak compared to the atomic transition frequency ω0 and the cavity field frequency ωc. However, in recent experiments in the context of circuit quantum electrodynamics, the atom-field coupling can be comparable to the atom and field frequencies so that the rotating wave approximation is no longer valid. A first goal of the present work is to examine the validity of the rotating-wave approximation in the context of circuit quantum electrodynamics. We also take into account the dissipation of the system, and to do that we have analyzed two different models: a phenomenological approach where the master equation is derived by adding the free decay of the atom and the field, regardless of the interaction between them, and another microscope, where the master equation is derived by taking into account the interaction between the atom and the field. We then investigate what happens when one has two atoms interacting with the same field in the cavity, considering, for example, the "spontaneous" generation of correlations between the atoms mediated by the field, that is, assuming initially all subsystems (atoms and field) in their ground states, we study the dynamics of correlations generated between the atoms. To quantify those correlations we employ measures as quantum discord and entanglement of formation.
O modelo de Rabi é o mais completo que se tem para entender a interação entre radiação e matéria. Entretanto, por não se ter uma solução exata para esse modelo, muitos trabalhos recentes têm recorrido ao modelo de Jaynes-Cummings, que elimina do Hamiltoniano do sistema os termos contragirantes , em um processo conhecido como Aproximação de onda girante . Essa aproximação tem sido bastante precisa para descrever os experimentos na área de Óptica Quântica nas últimas duas décadas, especialmente no contexto da Eletrodinâmica Quântica de Cavidades, onde o acoplamento átomo-campo g é muito fraco comparado com a frequência de transição atômica ω0 e a frequência da cavidade ωc. Entretanto, em recentes experimentos no contexto de Eletrodinâmica Quântica de Circuitos, o acoplamento átomo-campo tem atingido valores comparáveis aos das frequências do átomo e do campo, de modo que a aproximação de onda girante deixa de ser válida. É nesse contexto que esse trabalho se encontra, isto é, avalia as situações em que a aproximação de onda girante deixa de ser válida e mostra, através da análise de algumas propriedades do sistema, as diferenças devidas à escolha do modelo. Levamos também em conta a dissipação do sistema, e para isso analisamos dois modelos distintos: um fenomenológico, onde a equação mestra é deduzida adicionando-se os decaimentos do átomo e do campo independentemente da interação entre eles, e outro microscópico, onde a equação mestra é deduzida considerando-se a interação entre o átomo e o campo. Investigamos, então, o que acontece quando se tem dois átomos interagindo com o mesmo campo na cavidade, analisando, por exemplo, a geração "espontânea" de correlações entre os átomos mediada pelo campo, isto é, assumindo que todos os subsis- temas (átomo e campo) estão inicialmente no seus estados fundamentais, nós estudamos a dinâmica das correlações geradas entre os átomos. Para quantificar essas correlações utilizamos medidas de discórdia quântica e emaranhamento de formação.

Abstract:
Abstract An optical lattice is a periodic array produced by the superposition of two or more counter-propagating laser beams which interfere and create a spatial periodic intensity pattern. An important difference between a solid state crystalline lattice and an optically induced lattice is that the latter have a longer coherence time which permits the observation of coherent phenomenon such as Bloch oscillations. Recently, an interesting effect has been reported in the literature, which is the analogue of Rabi oscillations in two level systems driven by an external optical field: an optical beam composed by pair of frequencies, resonants with the high symmetry points of the Brillouin zone, propagating through an optical lattice exhibits oscillations of the Fourier ways between the frequencies due to the coupling with the lattice. Therefore, in the optical case the field plays the role of the matter, while the lattice plays the role of the driving field which couples the frequencies. Based in this result, the objective of this paper is to investigate the influence of self-defocusing in the optical Rabi oscillation. We have shown, through numerical calculation of the wave nonlinear equation, that in the self-defocusing optical lattice, these oscillations go disappearingare. The result of the disappearance of the oscillations of Fourier can be understood considering that self-defocusing promotes an addition of phases in the ways that were resonant - kB and kB, in different way, form that the basic difference between kB and - kB will not be plus a vector of the reciprocal net, and as consequence the oscillations of optic Rabi disappear, therefore the coupling with the net requires this condition in the resonant frequencies.

Resumo Uma rede opticamente induzida é um arranjo periódico produzido pela superposição de dois ou mais feixes de laser que ao interferirem criam um padrão de intensidade periódico espacial. Uma importante diferença entre uma rede cristalina no estado sólido e uma rede produzida opticamente é que a última apresenta um tempo de coerência longo, permitindo a observação de fenômenos coerentes tal como as oscilações de Bloch. Recentemente, um efeito interessante análogo às oscilações de Rabi em um sistema atômico de dois níveis impulsionado por um campo externo, foi publicado na literatura: um feixe óptico composto de um par de freqüências, ressonantes com os pontos de alta simetria da zona de Brillouin, propagando - se através de uma rede óptica exibe oscilações dos modos de Fourier entre as freqüências adequadas para o acoplamento com a rede. Portanto, no caso óptico o campo representa a matéria, enquanto a rede representa a intensidade do campo aplicado que acopla as freqüências. Baseado neste resultado, o objetivo desta dissertação é investigar a influência da auto - desfocalização nas oscilações ópticas de Rabi. Demonstraremos, através de cálculos numéricos da equação de onda não linear, que em uma rede opticamente induzida na presença da auto - desfocalização, essas oscilações vão desaparecendo. O resultado do desaparecimento das oscilações de Fourier pode ser compreendidoconsiderando que a auto - desfocalização promove um adicionamento de fases nos modos que eram ressonantes -kB e kB, de maneira diferente, de forma que a diferença básica entre kB e -kB não será mais um vetor da rede recíproca, e como conseqüência as oscilações de Rabi óptica desaparecem, pois o acoplamento com a rede requer esta condição nas freqüências ressonantes.

There were studied the variation of the solar ultraviolet radiation (UVR) in four wavelengths (305 nm, 320 nm, 340 nm e 380 nm) and erythemic dose, measured in Natal RN Brazil, from January 2001 until December 2007, using the ground ultraviolet radiometer of the Instituto Nacional de Pesquisas Espaciais / Centro Regional do Nordeste INPE-CRN, fixed on the roof of the Laborat?rio de Vari?veis Ambientais Tropiciais LAVAT-INPE-CRN. It was verified that the mean value of the UVR in the city reachs the HIGH index before 09h00 a.m. and VERY HIGH before 09h40 a.m.; it was also verified that, except in the months of June and July, in the other months of the year the UVR reachs the HIGH index before 10h00 a.m., despite of the recommendations broadcasting in the media about the safe time to people stay ashore on the beaches of the city. After 14h30 p.m., the UVR reachs the MODERATE index in any month of the year. These evidence are valid to all years of the period studied, i.e., 2001 to 2007. The year of 2004 presented the lower mean values of UVR indices, and the year of 2007 presented the higher mean values of UVR index. It was prove, by means of the analysis of variance (ANOVA), the variation in the four wavelengths and in the erythemic dose. Considering that the city has high indices of skin cancer and cataract, the results of the research may be use as a data source to studies that intend to support programs of public health. At the same time, the results of the research may be applied to material science and agriculture studies

Abstract:
Com o surgimento da criptografia de chave pública, muito esforço foi feito para a criação de protocolos de criptografia e de assinatura que fossem comprovadamente seguros contra indivíduos maliciosos. Existem várias definições de segurança, tanto para protocolos de criptografia como para protocolos de assinatura, e também existem vários modelos de adversários, que simulam um indivíduo malicioso tentando corromper o protocolo. A família de protocolos de assinatura Rabin possui os recordes de velocidade de vericação da assinatura, chegando a ser até 100 vezes mais rápida do que o RSA. Este trabalho apresenta uma redução eficiente de segurança no modelo do oráculo aleatório para uma variante do protocolo de assinatura Rabin descrito por Bernstein, onde não é necessário o uso de nenhuma função para geração de bits pseudo-aleatórios, o que torna o protocolo mais robusto. A redução apresentada é uma redução polinomial e eficiente do problema da fatoração de inteiros para o problema de quebrar o protocolo Principal Rabin-Williams B = 0.
With the development of public-key cryptography, many efforts were made to build encryption and signature protocols that were provably secure against malicious adversaries. There are many definitions of security for encryption and signature protocols, and there are many adversary models to simulate the behaviour of a malicious adversary against a given protocol. The Rabin family of signature protocols has the speed records for verification of signature, being up to 100 times faster than RSA. This work presents a tight security proof in the random oracle model for a variant of the Rabin signature protocol presented by Bernstein, that does not require the use of pseudo-random bits, making the protocol more robust. The proof presented here is a polynomially tight reduction for the problem of integer factorization to the problem of breaking the Principal Rabin-Williams B = 0 protocol.

Abstract:
Questo lavoro di tesi si pone l’obiettivo di studiare il fenomeno delle oscillazioni di Rabi tramite un approccio semiclassico e uno quantistico. Tali oscillazioni si osservano quando luce e materia interagiscono fortemente, cioè quando sono vicine alla risonanza. Il primo metodo utilizzato per studiare questa interazione è quello proposto da I.I. Rabi: questo modello descrive la più semplice interazione luce-materia possibile, quella tra un atomo a due livelli e un’onda elettromagnetica monocromatica. Successivamente viene affrontato il problema considerando più correttamente un'elettrodinamica quantistica, seguendo il modello ideato da Jaynes e Cummings. Tale formulazione, particolarmente semplice da risolvere analiticamente, è un’approssimazione del modello di Rabi quantistico, valida nella maggior parte delle situazionisperimentali. Dopo l’introduzione delle due Hamiltoniane nei rispettivi modelli, viene derivata la dinamica del sistema: sia nel modello semiclassico che il quello quantistico emergono naturalmente delle oscillazioni di popolazione dei livelli energetici, le oscillazioni di Rabi. Inoltre, nel caso quantistico vengono prese in considerazione diverse condizioni iniziali del campo elettromagnetico. Infine si illustra l’apparato sperimentale e il funzionamento generale degli esperimenti condotti da S. Haroche, i quali si basano sulla possibilità di modificare lo stato di un certo tipo di atomi attraverso le oscillazioni di Rabi.

Abstract:
This thesis analyzes the text of Genesis Rabba, one of the largest and most important of the rabbinic midrashim. It pays particular attention to its use of the term miyyad ("immediately"). Two specific patterns of usage are identified. Through these patterns, the thesis demonstrates how Genesis Rabba's midrash is simultaneously a work of narrative and of exegesis, and comments on some aspects of these two functions. It also traces the lexical evolution of the word miyyad in Hebrew.

Abstract:
The number of older persons is growing at a shocking rate. In spite of this reality, the South African health care sector does not prioritise older persons, causing their health to be poorly managed. Not only does poor health management affect the health of the older person, but also economic factors. This causes a high burden on the public health sector of South Africa, with specific reference to the Primary Health Care (PHC) clinics. PHC clinics in this country are not only overcrowded due to staff shortages, but also owing to the rapidly ageing population and the large number of younger persons affected by the high unemployment rate of South Africa. The above-mentioned factors keep the professional nurses in the clinic from spending time on proper physical examinations and provision of health education to older persons. This causes older persons to lack knowledge regarding self-care, potentially leading to unintentional self-neglect, which decreases their quality of life. Studies conducted on older persons concluded that the older person wants to be involved in health promotion, but needs the necessary knowledge to take care of him- or herself. Therefore, the researcher's overarching aim with this study was to develop guidelines to facilitate self-care amongst older persons. Such guidelines aim at constituting an indirect approach to promote the health of the older person. Health education on self-care should be conducted in self-care support groups, since community experience teaches that some older persons in the community do not apply self-care skills learned without some form of support. The aim with these guidelines is to decrease unintentional self-neglect by empowering the older person to make autonomous decisions regarding self-care, in order to increase quality of life. RESEARCH AIM AND OBJECTIVES In order to reach the overarching aim of this study, which comprises the development of guidelines to facilitate self-care amongst the older persons in the Potchefstroom district, the study firstly includes a literature review to understand self-care and related constructs from a theoretical perspective. Secondly, the Appraisal of self-care agency scale-A (ASA-A) and Exercise of self-care agency scale (ESCA) were used as questionnaires to assess the self-care of the selected older persons. Lastly, after determining the self-care of the older persons, the study investigates the relationship between these two questionnaires through correlational analysis. RESEARCH DESIGN A quantitative, descriptive, correlational and contextual design was used in this study to .reach the overarching aim and respective objectives. RESEARCH METHOD The researcher firstly conducted a literature review to understand self-care and related constructs. Thereafter the researcher employed two structured questionnaires, the ASA-A and ESCA, were employed to collect data. The questionnaires were developed to measure self-care (self-care is determined by measuring the self-care agency). These questionnaires were based on Dorothea OrenYs self-care deficit theory of nursing, the same theory that this research study is based on. Minor adaptations were made to both the questionnaires prior to administration to the predominantly Setswana-speaking older population. The study formed part of the larger Multinational Prospective Urban and Rural Epidemiological study (PURE-SA study - ethical approval number 04M10). All the older persons identified in the peri-urban population of the PURE-SA study living in the Potchefstroom district and who were willing to participate were included in the sample. Trained fieldworkers assisted the researcher in data collection. Of the 198 older persons, 192 participated, accumulating to a 98% response rate. Lastly the researcher correlated the ASA-A and ESCA to determine their relationship as an added benefit to this research study. RESULTS The findings indicate that although the studied older population was of a lower socio-economic status with a lower literacy level, their overall self-care was relatively good. Seven self-care deficits were identified namely time management skills affecting self-care, energy deficit affecting self-care, sleep deprivation, lack of knowledge and ability to acquire knowledge with regard to health and self-care, lack of a rest, exercise and self-care programme, self-care deficit caused by physical deterioration and, lastly, the lack of performance of activities to prevent/decrease self-care deficits. These identified self-care deficits supported the development of guidelines to facilitate self-care amongst older persons, together with Menon's psychological health empowerment model, as well as an in-depth literature review on self-care and related constructs to understand self-care from a theoretical perspective. Furthermore, the study compared the ASA-A and ESCA questionnaires to determine the relationship between these questionnaires. The two questionnaires had a very good correlation with each other, conclusion that either of these two questionnaires could be used to measure self-care of a population.

Abstract:
In order to reduce the amount of pollution that is generated by burning fossil fuels alternative energy sources should be explored. Hydrogen has been identified as the most promising replacement for fossil fuels and can be produced by using the Hybrid Sulphur (HyS) cycle. Currently the SO2/O2 separation step in the HyS process has a large amount of knock out drums. The aim of this study was to investigate new technology to separate the SO2 and O2. The technology that was identified and investigated was to separate the SO2 and O2 by absorbing the SO2 into an ionic liquid. In this study the maximum absorption, absorption rate and desorption rate of SO2 from the ionic liquid [BMIm][MeSO4] with purities of 95% and 98% was investigated. These ionic liquid properties were investigated for pure O2 at pressures ranging from 1.5 to 9 bar(a) and for pure SO2 at pressures from 1.5 to 3 bar(a) at ambient temperature. Experiments were also carried out where the composition of the feed-stream to the ionic liquid was varied with compositions of 0, 25, 50, 75 and 100 mol% SO2 with O2 as the balance. For each of these compositions the temperature of the ionic liquid was changed from 30oC to 60oC, in increments of 10oC. The absorption rate of SO2 in the ionic liquid increased when the mole percentage SO2 in the feed stream was increased. When the temperature of the ionic liquid was decreased the maximum amount of SO2 that the ionic liquid absorbed increased dramatically. However, the absorption rate was not influenced by a change in the absorption temperature. The experimental results for the maximum SO2 absorption were modelled with the Langmuir absorption model. The model fitted the data well, with an average standard deviation of 17.07% over all the experiments. In order to determine if the absorption reaction was endothermic or exothermic the Clausius-Clapeyron equation was used to calculate the heat of desorption for the desorption step. The heat of desorption data indicated that the desorption of SO2 from this ionic liquid was an endothermic reaction because the heat of desorption values was positive. Therefore the absorption reaction was exothermic. From the pressure-change experiments the results showed that the mole percentage of O2 gas that was absorbed into the ionic liquid was independent of the pressure of the O2 feed.On the other hand, there was a clear correlation between the mole percentage SO2 that was absorbed into the ionic liquid and the feed pressure of the SO2. When the feed pressure of the SO2 was increased the amount of SO2 absorbed also increased, this trend was explained with Fick’s law. In the study the effect of the ionic liquid purity on the SO2 absorption capacity was investigated. The experimental results for the pressure experiments showed that the 95% and 98% pure ionic liquid absorbed about the same amount of SO2. During the temperature experiments the 95% pure ionic liquid absorbed more SO2 than the 98% pure ionic liquid for all but two of the experiments. However the 95% pure ionic liquid also absorbed small amounts of O2 at 30 and 40oC which indicated that the 95% pure ionic liquid had a lower selectivity than the 98% pure ionic liquid. Therefore, the 95% pure ionic liquid had better SO2 absorption capabilities than the 98% pure ionic liquid. These result showed that the 98% pure ionic liquid did not absorb more SO2 than the 95% pure ionic liquid, but it did, however, show that the 98% pure ionic liquid had a better selectivity towards the SO2. Hence, it can be concluded that even with the O2 that is absorbed it would be economically more advantageous to use the less expensive 95% pure ionic liquid rather than the expensive 98% pure ionic liquid, because the O2 would not influence the performance of the process negatively in such low quantities.

Perfis taxon?micos comparativos de ambas as amostras mostraram alta abund?ncia do Dom?nio Bacteria, seguida por uma pequena parcela atribu?da aos Dom?nios Eucaryota, Archaea e V?rus. Proteobacteria, Actinobacteria e Bacterioidetes foram os filos que mostraram maior domin?ncia em ambas as amostras. Importantes g?neros e esp?cies associados ? resist?ncia aos agentes estressores encontrados na regi?o foram observados. Sequ?ncias relacionadas ? replica??o e reparo do DNA, ao estresse oxidativo e estresse pelo calor e a resist?ncia a compostos t?xicos foram observadas, mostrando uma importante rela??o entre a microbiota e seu perfil metab?lico, influenciada pelas vari?veis ambientais regionais. Os resultados encontrados neste estudo adicionam valiosos e in?ditos dados sobre a composi??o de comunidades microbianas nestas regi?es.
Many species have specialized to live in the most varied existing environments showing the remarkable adaptability of the microbial world the most diverse physicochemical conditions. Environments exposed to natural radiation and metals are scarce around the world, presenting a microbiota still unknown. With a total number estimated between 4 and 6 x 1030 microrganisms on earth, they constitute an enormous biological and genetic pool to be explored. Metagenomic approach independent of cultivation, provides a new form to access to the potential genomic environmental samples becoming a powerful tool for the elucidation of ecological functions, metabolic profiles, as well as to identify new biomolecules. In this context, the genetic material of environmental soil and water samples from A?ude Boqueirao Parelhas-RN, under the influence of natural radiation and the presence of metals, was extracted, pirosequencing and the generated sequences were analyzed by bioinformatics programs (MG-RAST and STAMP). Taxonomic comparative profiles of both samples showed high abundance of Domain Bacteria, followed by a small portion attributable to Eucaryota Domains, Archaea and Viruses. Proteobacteria, Actinobacteria and Bacterioidetes phyla showed the greater dominance in both samples. Important genera and species associated with resistance to various stressors found in region were observed. Sequences related to oxidative and heat stress, DNA replication and repair, and resistance to toxic compounds were observed, suggesting a significant relationship between the microbiota and their metabolic profile, influenced by regional environmental variables. The results of this study add valuable and unpublished data on the composition of microbial communities in these regions
