Common bermudagrass [Cynodon dactylon (L.) Pers.] and hybrid bermudagrass [C. dactylon (L.) Pers. X C. transvaalensis Burtt-Davy] are some of the most common turfgrasses used on athletic fields. Subsequently, the traffic tolerance of commercially available cultivars and the effects of trinexapac-ethyl (TE) on bermudagrass athletic fields with or without perennial ryegrass are often limited. A two year study at the University of Tennessee was conducted under simulated athletic field traffic to evaluate the performance of bermudagrass cultivars as affected by TE and overseeding. Bermudagrass cultivars evaluated were Tifway, Riviera, Patriot, and Celebration. TE treatments consisted of an untreated control, TE at 76.3 g a.i. ha-1 every 14 days until 14 days prior to trafficking (TE A), and TE at 76.3 g a.i. ha-1 every 14 days until 14 days after trafficking (TE B). Overseeding treatments consisted of no overseeding and overseeding at 670 kg ha-1 of perennial ryegrass (Lolium perenne L.). Plots were rated for percent green cover using digital image analysis after every 5 traffic events. Soil physical characteristic measurements were performed after every traffic season. Morphological data was determined by measuring number of leaves, internode lengths, leaf angle, and leaf width of the bermudagrass. Cultivar was significant for percent green cover for both years of this study with Tifway and Celebration having the highest ratings and Patriot having the lowest rating. TE was also significant for percent green cover for the first 10 traffic events with TE treatment B having lower percent cover values. Morphological characteristic was significant for leaf angle for both years of the study. A more vertical leaf angle to the shoot occurred in the more traffic resistant cultivars Tifway and Celebration. Finally, both TE treatments yielded higher percent green cover values in 2008 when morphological characteristic data was collected and a more vertical leaf angle to the shoot occurred compared to the untreated control. Tifway, Celebration, and Riviera when applied with trinexapac-ethyl before the traffic season and overseeded with perennial ryegrass would be beneficial for athletic field managers.

La traducción en el siglo XV establece una tercera vía: traducir un texto del latín o del griego "ad sententiam", segun su significado; alternativa a los dos "modi" medievales, que son la traducción "ad verbum" o literal, y la traducción "ad sensum", segun su sentido. La traducción del significado incluye la comprensión histórica y los aspectos formales y estilísticos del texto, fundamentos hermenéuticos esenciales para su correcta comprensión. Un primer paso de esta concepción moderna de la traducción se da en traductores que corrigen textos anteriores, como F. Alegre en las "Transformacions" (1494) de P. Ovidio, influido por las tesis de L. Bruni i por la poética neoplatónica. En su traducción "La primera guerra púnica" (1472), traduida del italiano, el barcelonés se situa al margen de estas inovaciones y se mantiene en el binomio "verbum-sensum" por la naturaleza escolar e iniciática de este ejercicio.

Este autor é um judeu italiano, personagem central de sua obra, que consiste no testemunho daquilo que viveu em Auschwitz, um dos maiores campos de concentração nazista. No livro, o autor recria, por meio da linguagem, um mundo extraliterário, o do campo, com sua arquitetura própria, sua organização interna e suas formas de controle e extermínio. Primo Levi narra as atrocidades cometidas por seres humanos contra outros seres humanos, de uma forma bárbara, deixando claro que, quando a luta é pela sobrevivência, os valores éticos e morais são postos à prova; ao mesmo tempo em que, no caso do carrasco, verdadeiras faces se revelam, trazendo à tona a força da barbárie e sua capacidade de ultrapassar todos os limites humanos. Primo Levi narra os fatos sentindo-se como que incumbido de um dever moral para com a sociedade, dever de falar em nome daqueles que não sobreviveram. Apesar da dificuldade de representação de sua experiência traumática, Levi expõe todo um sistema burocraticamente organizado que possibilitou que Auschwitz chegasse a ser o próprio horror; lugar onde a razão instrumentalizada desfez os princípios iluministas de progresso e animalizou os homens, condenados a uma violência destrutiva e mortífera, que, por sua vez, foi subsidiada pela própria noção de progresso e desenvolvimento técnico que marcou os ideais da modernidade. / This work aims at studying the relationship that exists among modernity, rationalization and violence in the book Is this a man?, by Primo Levi. This author is an Italian Jewish, the central character of his book, which consists in the testimony of what he lived in Auschwitz, one of the biggest Nazi concentration camps. In the book, the author recreates, through language, an extra literary world, that of the camp, with its own architecture, its organization and ways of control and extermination. Primo Levi tells the atrocities committed, in a barbaric way, by human beings against other human beings, which makes clear that, when the fight is for survival, ethical and moral values are tested; likewise, in the case of the executioner, true faces are revealed, showing the force of barbarism and its capacity of exceeding all the human limits. Levi tells the facts feeling as if in charge of a moral duty towards the society, the duty of speaking for those who did not survive. Despite the difficulties of representation of his traumatic experience, Levi exposes the whole bureaucratically organized system that made possible that Auschwitz ended up being the horror itself; the place where the instrumentalized reason destroyed the illuminist principles of progress and made men become animals, condemned to a destructive and deadly violence, that was subsidized by the notion of progress and technical development, which were signals of the modernity purposes.

La phase de primo-infection à VIH qui correspond aux premières semaines de l'infection est une phase cruciale qui détermine en partie l'évolution clinique de la maladie. La dynamique du virus et des lymphocytes T CD4+ (principale cible) durant cette phase est complexe. D'une part cette phase est asymptomatique dans plus de la moitié des cas et est semblable à un syndrome grippal; elle passe par conséquent très souvent inaperçue et peu de données sont disponibles. D'autre part la date d'infection est généralement inconnue ce qui complique l'étude de l'évolution au cours du temps des marqueurs viro-immunologiques. Les modèles dynamiques basés sur des systèmes d'équations différentielles permettent de prendre en compte l'interaction complexe et non-linéaire existant entre le VIH et le système immunitaire. De plus, leur aspect mécanistique peut être très utile pour la compréhension de la physiopathologie ou l'effet d'intervention. Cependant l'estimation de ces modèles est complexe et plusieurs méthodes sont disponibles à ce jour. Nous proposons dans cette thèse une méthode d'estimation pour des modèles dynamiques prenant en compte l'incertitude sur la date d'infection. Nous appliquons cette méthode à un jeu de données réelles de 761 séroconverteurs de la Collaboration CASCADE durant leur première année de suivi. Ces modèles possèdent un grand nombre de paramètres pouvant inclure des effets aléatoires et des variables explicatives. La sélection du meilleur modèle peut nécessiter l'estimation d'un grand nombre de modèles et peut s'avérer très longue. Nous proposons des tests du score pour sélectionner les effets aléatoires et les variables explicatives plus rapidement dans le cadre général des modèles non-linéaires à effets mixtes avec une illustration sur des modèles dynamiques. Enfin, nous proposons de comparer plusieurs modèles biologiques possibles de la primo-infection à VIH pour prédire la dynamique de la charge virale plasmatique et des CD4. / Primary HIV infection, which corresponds to the first weeks of infection, is a crucial phase which determines partly the clinical progression. The dynamics of HIV viral load and CD4 count during this phase is complex. First, as it is asymptotic in most of the cases, the primary HIV infection is not observed. Moreover, the date of infection is generally unknown and the evolution of markers with respect to the time of infection is difficult. Dynamical models based on systems of ordinary differential equations (ODE) allow to take into account complex non-linear between HIV and the immune system. Moreover, their mechanistic characteristic can be useful through the understanding of physiopathology or the effect of an intervention. However, the estimation of this kind of models is complex and several methods are currently available. We propose here a method of estimation for ODE models taking into account the uncertainty of the date of infection. This method is applied to real dataset of 761 seroconverters from the CASCADE Collaboration during their first year of follow-up. Dynamical models have many parameters on which we can include random effects and explanatory variables. The selection of the best model can be time-consuming if we consider the computation's time issues met during estimation. We develop score tests for exploring complex models with an application to HIV dynamics models. Finally, we compare different biological models of primary HIV infection to predict the dynamics of plasma viral load and CD4 count.

Forty-two male Nelore cattle, divided into three groups (n = 14): control group (CG) received 70 grams of mineral mixture/animal/day; probiotic groups 4 grams (G4P) and 8 grams (G8P) received 70 grams of mineral mixture/animal/day with 4 and 8 grams of added probiotics respectively. The individual anti-rabies antibody titers were determined using the technique of seroneutralization in cells based on the Rapid Fluorescent Focus Inhibition Test (RFFIT). The results obtained were compared using the unpaired t test with a 5% significance level. There were statistical differences in the mean serum concentrations between the CG, G4P and G8P groups, 30 and 60 days after the primo vaccination and after 60 days only the G8P group demonstrated minimum protective antibody titers in 100% of the animals. There is evidence of beneficial effects attributed to the association between probiotic microorganisms and the anti-rabies humoral immune response; in addition, an increase in the dose incorporated into the mineral mixture maintains high levels of serum antibodies in primo vaccinated cattle. / Esse estudo avaliou o efeito da suplementação de uma associação de microrganismos probióticos, adicionados à mistura mineral em diferentes doses/dia, na produção de anticorpos séricos contra o vírus rábico em bovinos primovacinados. Quarenta e dois bovinos Nelore machos, divididos em três grupos (n=14): grupo controle (GC) recebeu 70 gramas de mistura mineral/animal/dia; grupos probióticos 4 gramas (G4P) e 8 gramas (G8P) receberam 70 gramas de mistura mineral/animal/dia adicionados respectivamente de 4 e 8 gramas de probióticos. Os títulos individuais de anticorpos antirrábicos foram determinados por meio da técnica de soroneutralização em células baseado no Rapid Fluorescent Focus Inhibition Test (RFFIT). Os resultados obtidos foram comparados pelo teste t não pareado, com 5% de nível de significância. Houve diferenças estatísticas significativas entre as médias de concentrações séricas entre os grupos GC e os G4P e G8P, após 30 e 60 dias da primovacinação e após 60 dias somente o G8P manteve 100% dos animais com títulos de anticorpos protetores mínimos. Existem evidências para se atribuir efeito benéfico à associação de microrganismos probióticos na resposta imune humoral antirrábica e ao aumento da sua dose incorporada na mistura mineral e sobre a manutenção de elevados níveis de concentração sérica de anticorpos nos bovinos primovacinados.
