From Ancient Greece until now, it has been used and studied. In religion, is a formidable source of expression. It was through the rhetoric that Pope John Paul II managed to gain notoriety and engage in cases far beyond religion in the 20th century. He was considered a Pope who used politics and consolidated a new status for the Catholic Church. Thus by analysing the rhetoric of mediation of the Holy see on Beagle Channel in 1979 and rhetorical analysis of Vatican diplomatic actions against the invasion o f Iraq in 2003, this work shows how the religious rhetoric is build, in addition to the consequences that this entails not only for the Church but also to the world. / A retórica sempre esteve presente nas civilizações. Desde a Grécia Antiga até os dias de hoje ela é usada e estudada. Na religião, é uma formidável fonte de expressão. Foi através da retórica que o Papa João Paulo II conseguiu ganhar notoriedade e se envolver em casos muito além da religião no século XX. Ele foi considerado um papa que se utilizou do político e consolidou um novo status para a Igreja Católica. Assim, através da análise retórica da mediação da Santa Sé no Canal de Beagle em 1979 e da análise retórica das ações diplomáticas do Vaticano contra a invasão do Iraque em 2003, este trabalho mostra como se constrói a retórica religiosa, além das conseqüências que isso acarreta não só para a Igreja, como também para o mundo.

Com o objetivo de avaliar a influência do processo de cicatrização óssea sobre o desempenho biomecânico de mini-parafusos utilizados como ancoragem em ortodontia, foram inseridos 60 mini-parafusos (1,6 x 6mm) auto-rosqueantes (Tomas® Dentaurum / Germany) na maxila e na mandíbula de 5 cães adultos da Raça Beagle. Os pré-molares (P1, P2, P3, P4) superiores e inferiores foram extraídos três meses antes da inserção vertical dos mini-parafusos. Os cães foram sacrificados nos dias 0, 2, 7, 15 e 30 após a instalação dos mini-parafusos. Os maxilares foram dissecados e os corpos de provas contendo os mini-parafusos foram preparados para avaliação da resistência à tração na Máquina de Ensaios Universal EMIC® 2000, utilizando uma garra desenvolvida especificamente para este estudo. Os valores e gráficos correspondentes ao desempenho mecânico foram imediatamente gerados e registrados pelo programa de aquisição Tesc 3.01®. As possíveis diferenças entre os períodos de cicatrização foram avaliadas pela análise de variância (ANOVA) e pelo teste de comparações múltiplas de Bonferroni. Os resultados demonstraram um índice de sucesso de 100% dos mini-parafusos inseridos. Após a dissecação dos segmentos ósseos, verificou-se que em alguns casos a superfície da rosca ficou parcialmente exposta, razão pela qual o cálculo da resistência à tração (média na maxila de: 141,76 ± 92,82 Ncm a 237,02 ± 78,34 Ncm e média na mandíbula de: 156,86 ± 75,55 Ncm a 328,76 ± 82,17 Ncm) foi feito em relação à área real de inserção (maxila: 24,01 ± 6,09mm2 e mandíbula: 22,88 ± 5,31mm2), observando-se um valor médio por mm2 significativamente maior na mandíbula (11,60 ± 5,22 Ncm) quando comparado à maxila (8,22 ± 5,04 Ncm). A relação entre a intensidade da força de tração (Ncm), superfície inserida (mm2) e períodos de cicatrização não apresentaram diferenças significantes (p= 0,126). Com base nestes resultados podemos concluir que os mini-parafusos avaliados demonstraram excelente desempenho biomecânico nos diferentes períodos de cicatrização analisados, apresentando maior resistência à tração no osso mandibular. / With the purpose of evaluating the influence of bone healing process on the biomechanical performance of mini-screws used as anchorage in orthodontics, 60 self-tapping (Tomas® - Dentaurum / Germany) mini-screws were inserted (1.6 x 6 mm) in the maxilla and in the mandible of 5 adult Beagle dogs. Upper and lower premolars (P1, P2, P3, P4) were extracted three months before the vertical insertion of mini-screws. The dogs were sacrified on days 0, 2, 7, 15 and 30 after the insertion of mini-screws. The jaws were dissected and the bone blocks, containing the miniscrews, were prepared to the axial pull-out strength in the Universal Testing Machine EMIC ® 2000, using a device developed specifically for this study. The values and graphics for the mechanical performance were immediately generated and recorded by the acquisition program. The clinical success rate of mini-screws was 100%. The possible differences between the healing periods were analyzed by Bonferroni´s multiple test comparisons and variance analysis (ANOVA). After the dissection of the bone segments, it was found that in some cases, the mini-screw thread was not fully inserted into the bone, reason why the pull-out strength (average of the maxilla: 141.76 ± 92.82 Ncm to 237.02 ± 78.34 Ncm and average in the mandible of 156.86 ± 75.55 Ncm to 328.76 ± 82.17 Ncm) was evaluated in relation to the real area of insertion (maxilla: 24.01 ± 6.09 mm2 and mandible: 22.88 ± 5.31 mm2). Mean value/mm2 were significantly higher in the mandible (11.60 ± 5.22 Ncm/mm2) than the maxilla (8.22 ± 5.04 Ncm/mm2). There was no statistically significant difference (p = 0126) between pull-out strength (Ncm), surface inserted (mm2) and the observed healing periods. Based on these results it can be concluded that mini-screws evaluated in this study demonstrated an excellent biomechanical behavior in all different periods of healing, showing more resistance to traction in the mandibular bone.

This project examines the landscape of the farming community of Beagle, Oregon prior to and during the Second World War and the effect on it due to the construction of Camp White, a World War II training facility. The Beagle landscape is examined through the prism of current theory that suggests that landscapes are not discrete units of analysis but are, instead, symbiotic relationships between land and people. Utilizing archives, contemporary newspaper accounts, photographs, oral histories, and archaeological investigation, the history of the construction of Beagle landscape, the effects of the construction of Camp White, the subsequent removal of Beagle residents, and postwar renewal are examined. The project concludes that the Beagle landscape was, and is, a holistic entity that, though dramatically changed in 1942, continues to exist and inform the lives of surviving original residents as well as the history of the Beagle area. / Graduation date: 2007

La presente tesis se ha basado en conseguir dos objetivos fundamentales: diseñar un protocolo clínico de electrodiagnóstico para obtener el electrorretinograma (ERG) y los potenciales evocados visuales (PEV) en el perro beagle, y elaborar un estándar de los resultados para esta raza.Hemos establecido un protocolo clínico de electrodiagnóstico adaptado a nuestro equipo de diagnóstico, a las características de nuestros pacientes y, en general, a los recursos materiales que teníamos a nuestra disposición. De este modo, hemos conseguido realizar un protocolo de corta duración que nos permite evaluar la funcionalidad de las vías visuales del perro y detectar posibles anomalías.Concluimos que el protocolo que hemos establecido nos permite registrar adecuadamente el ERG y los PEV para el perro beagle, así como obtener resultados fiables y reproducibles que podemos considerar como estándar para esta raza canina y este equipo de electrodiagnóstico. / The aims of this thesis were firstly to design a clinical protocol for Electro, electroretinography (ERG) and visual evoked potential (VEP) in the Beagle dog and, secondly, to develop a performance standard for this breed. A clinical electrodiagnostic protocol adapted to our diagnostic equipment was established. This protocol considered the characteristics of the patients as well as the material resources at our Institution. This protocol allowed us to evaluate the functionality of the visual pathways in order to detect any anomalies. It can be concluded that the protocol established in this Thesis allows to record accurately the ERG and the VEP of Beagle dogs. Moreover, the results are reliable and reproducible and it could be considered as a good standard for this breed when these electrodiagnosis tools are employed.

Plusieurs articles scientifiques et manuels de référence en médecine comportementale distinguent l'hyperactivité ou hyperkinésie de l’activité excessive en évaluant la réponse physiologique et comportementale des chiens suite à l’administration per os de 0.2 à 1.0 mg/kg de dextroamphétamine. Selon ces références, le chien atteint d’un syndrome hyperactif ou hyperkinésie, répondra de façon paradoxale à cette médication par une diminution de l’activité motrice accompagnée d’une réduction minimale de 15% de la fréquence respiratoire et de la fréquence cardiaque. L’objectif de la présente étude était de mesurer la variation de la température corporelle, de la fréquence cardiaque, de l’activité motrice et de différents comportements spécifiques chez un groupe de Beagles ayant reçu de la dextroamphétamine. La fiabilité d'un accéléromètre comme mesure objective d’activité motrice a aussi été évaluée. Dans le cadre de cette étude croisée contrôlée par placebo, douze Beagles de la colonie de recherche âgés entre 13 et 20 mois ont reçu une dose orale de 0.2 mg/kg de dextroamphétamine. Le moniteur cardiaque Polar® et un accéléromètre Actical® ont été utilisés pour enregistrer la fréquence cardiaque et l’activité motrice avant et après l’administration de la médication. La durée de chacun des comportements spécifiques a été compilée à l’aide du logiciel Noldus® et la température corporelle a été prise par thermomètre rectal. Le modèle équilibré de mesures répétées indique que les sujets ayant reçu la dextroamphétamine montrent une réduction significative (p = 0.044) de leur fréquence cardiaque comparativement aux chiens ayant reçu le placebo. Aucune variation significative n'a été observée concernant la température corporelle, l'activité motrice, et les autres comportements (léchage des babines, halètements, et bâillements) suite à l’administration de la dextroamphétamine. Une corrélation significative, linéaire et positive (p < 0,0001) entre les périodes de mouvements observées (vidéo) et les mesures d’activité enregistrées par l’accéléromètre a été observée. Les résultats de cette étude indiquent que les Beagles peuvent afficher des effets paradoxaux dans les 90 minutes suivant l’administration per os de dextroamphétamine à raison de 0.2 mg/kg. / Several veterinary behaviour texts/handbooks used in practice, distinguish hyperactivity or hyperkinesis from over-activity by using the physiological and behavioural responses of dogs given amphetamines. It is presumed that true hyperactive or hyperkinetic dogs given 0.2 - 1.0 mg/kg dextroamphetamine orally will paradoxically calm down, and have at least a 15% reduction in heart and respiratory rates. The purpose of the study was to measure the effects of an oral dose of 0.2 mg/kg dextroamphetamine on heart rate, body temperature, motor activity, and discrete behaviour sequences in Beagle dogs. Reliability of a collar mounted accelerometer, Actical® as an objective measure of motor activity was also investigated. The study design was a placebo controlled cross-over study. Twelve research colony Beagle dogs (13 - 20 months old) received an oral dose of 0.2 mg/kg dextroamphetamine as treatment. Baseline and post-treatment values for body temperature, heart rate, motor activity, and general behavioural changes, were obtained using rectal temperature, video recordings and Noldus® software, Polar® monitor (heart rate), and a collar mounted Actical®. A repeated measures model indicates that dogs receiving an oral dose of 0.2 mg/kg dextroamphetamine had a significantly (p = 0.044) reduced heart rate compared to placebo. There was no effect of treatment on the dogs’ body temperature, motor activity, or other behaviours such as “lip-licking”, “panting” and “yawning”. There is a significant linear and positive relationship between the gross motor activity as measured by observational video and the Actical® counts (p < 0.0001). Results from this study indicate that Beagle dogs may display some paradoxical effects in the 90 minutes following an oral dose of 0.2 mg/kg dextroamphetamine.

Informe de Seminario para optar al grado de Licenciado en Historia / Este trabajo se inscribe dentro del seminario de grado “Nacionalismos y territorialidades”. Desde la discusión grupal de los principales lineamientos teóricos de dicho tema, el presente surge como una forma de entender lo teórico desde lo práctico y viceversa. Me propongo tratar las repercusiones del nacionalismo en el conflicto limítrofe que tuvo cercano a una guerra a los dos países más australes del continente americano en 1978, debido a su insanable diferencia de opinión respecto de la soberanía del canal del Beagle y sus islas adyacentes: Nueva, Picton y Lennox.

We have previously shown that diets enriched with (n-3) fatty acids reduced the delayed-type hypersensitivity (DTH) skin reaction to keyhole limpet haemocyanin (KLH) in geriatric-Beagles. Although the amount of ��-tocopheryl acetate in diets of the previous study exceeded requirements, plasma ��-tocopherol concentration was significantly lower in dogs fed the high (n-3) fatty acid diets. There are several reasons that could explain the decreased DTH response. Some of these include decreased cytokine production, specifically, interleukin (IL) IL-1��, tumor necrosis factor (TNF) and IL-6 by mononuclear cells. Furthermore, the reduced DTH response could be attributed to increased levels of lipid peroxides or changes in plasma ��-tocopherol levels. In this study we examined the effects of feeding 32 healthy, female, geriatric-Beagles diets containing (n-6) to (n-3) fatty acid ratios of 37:1 and 1.7:1, while varying the content of ��-tocopheryl acetate, [high (447 ug/g), med (101 ug/g) and low (17 ug/g)] for 82 days on the DTH reaction. Consumption of the 1.7:1 fatty acid diets significantly increased the total content of (n-3) fatty acids in plasma compared to the 37:1 fatty acid diets (17.00 and 2.02 wt %, respectively). There was a significant interaction between the (n-6) and (n-3) fatty acid ratio and the concentration of ��-tocopheryl acetate in the diet on the plasma concentration of ��-tocoopherol. The concentration of ��-tocopheryl acetate in plasma of dogs fed the 1.7:1 fatty acid diets was 17.3, 25.4, and 35.4 ug/ml, respectively, for the low, med and high ��-tocopheryl acetate containing diets, and in dogs fed the 37:1 fatty acids diets was 20.8, 34.9, 52.4 ug/ml, respectively. Consumption of the 1.7:1 fatty acid diets with either low or high ��-tocopheryl acetate showed no differences in DTH response from each other or from dogs consuming the 37.1:1 fatty acid diets. When the dietary ��-tocopheryl acetate concentration was moderate, a significant suppression of the DTH response occurred at 48, 72, and 96 hr in dogs consuming the 1.7:1 fatty acid diet. These data suggest that an interaction exits between dietary (n-3) fatty acid content and ��-tocopheryl acetate on the immune response as measured by the DTH test. / Graduation date: 2000
