Origins of Australian Football: Victoria's Early History. Volume 1 Amateur Heroes and the Rise of the Clubs, 1858 to 1876

This is volume 1 in a series of four volumes about the origins of Australian football as it evolved in Victoria between 1858 and 1896. This volume addresses its very beginnings as an amateur sport and the rise of the first clubs. Invented by a group of Melbourne cricketers and sports enthusiasts, Australian Rules football was developed through games played on Melbourne's park lands and was originally known as "Melbourne Football Club Rules". This formative period of the game saw the birth of the first 'amateur heroes' of the game. Players such as T.W. Wills, H.C.A. Harrison, Jack Conway, George O'Mullane and Robert Murray Smith emerged as warriors engaged in individual rugby-type scrimmages. The introduction of Challenge Cups was an important spur for this burgeoning sport. Intense competition and growing rivalries between clubs such as Melbourne, South Yarra, Royal Park, and Geelong began to flourish and the game developed as a result. By the 1870s the game "Victorian Rules" had become the most popular outdoor winter sport across the state. In subsequent decades, rapid growth in club football occurred and the game attracted increasing media attention.

Creating dangerously: literature as an instrument of resistance in the works of Edwidge Danticat

O objetivo desta dissertação é discutir o lugar que o fazer literário ocupa no processo de resistência à poderes hegemônicos. Como fontes primárias centrais, foram escolhidos o romance histórico The Farming of Bones (1998) e a narrativa autobiográfica Brother, Im Dying (2007), ambos escritos pela autora haitiana-americana Edwidge Danticat. Em The Farming of Bones, Danticat reconstrói ficcionalmente o trágico e obscuro episódio ocorrido em 1937 quando o então ditador da República Dominicana, Rafael Trujillo, ordenou o extermínio de todos os haitianos que residiam e trabalhavam em cidades dominicanas próximas à fronteira com o Haiti. O silêncio por parte dos governos de ambos os países em torno do massacre ainda perdura. A publicação do romance histórico de Danticat 61 anos após tal ato de terrorismo de Estado se torna, desta forma, exemplo de como o fazer literário e o fazer histórico podem fundir-se. Em Brother, Im Dying, Danticat narra a história da vida e da morte de suas duas figuras paternas, seu pai Andre (Mira) Dantica e seu tio Joseph Dantica (que a criou dos 4 aos 12 anos, no Haiti). Joseph, sobrevivente de um câncer de laringe, foi pastor batista e fundador de uma igreja e uma escola no Haiti. Morreu dois dias depois de pedir asilo político nos EUA e ser detido na prisão Krome, em Miami. Mira, que migrara no início da ditadura de François Duvalier para os EUA, onde trabalhou como taxista, morreu vítima de fibrose pulmonar poucos meses depois de seu irmão mais velho. Edwidge Danticat recebeu a notícia de que o quadro de seu pai era irreversível no mesmo dia em que descobriu que está grávida de sua primeira filha. Com uma escrita que abrange tanto a narrativa de si quanto a narrativa do outro, além das esferas públicas e privadas, Danticat cria em Brother, Im Dying um locus de fazer auto/biográfico que dialoga com questões de diáspora, identidade cultural e memória. Os ensaios publicados em Create Dangerously (2010) e as várias entrevistas concedidas por Danticat também reforçam meu argumento que Edwidge Danticat exerce seu papel de artista engajada através de seu fazer principalmente, mas não exclusivamente literário. Desta forma, a autora constrói uma possibilidade de resistência ao discurso hegemônico que opera tanto em seu país de origem quanto em seu país de residência.

Ressonâncias de heróis e reis medievais na (re)construção dos personagens da Pedra do Reino por Ariano Suassuna

A presente tese está calcada na análise da obra de Ariano Suassuna, o Romance dA Pedra do Reino e o príncipe do sangue do vai-e-volta, considerado pelo autor como a sua obra maior e, a princípio, o primeiro volume da trilogia A maravilhosa desaventura de Quaderna, o decifrador, e no primeiro volume da segunda parte da trilogia, O rei degolado ao Sol da Onça Caetana. O trabalho consiste, fundamentalmente, em examinar o diálogo estabelecido entre a obra de Suassuna com textos representativos da tradição literária ocidental, mais propriamente com os que remontam ao medievo. Para isso, fez-se um recorte nas relações que o romance trava com a matéria cavaleiresca, principalmente com a Demanda do Santo Graal, na sua estrutura e no desenho psicológico e moral dos personagens, notadamente de Sinésio, que encarna o mito do herói prometido, cujos paradigmas se assentam na figura lendária do Rei Artur, além de Galaaz, e na histórica de D. Sebastião, o rei desaparecido de Portugal. Sabe-se que esses reis e heróis míticos, considerados salvadores, uma vez que retornariam para restituir ao povo a dignidade e a liberdade perdidas, povoaram o imaginário ibérico e chegaram ao Brasil trazidos pelos colonizadores europeus. Dessa forma, a cultura popular do Nordeste brasileiro é povoada de histórias e lendas eternizadas e recriadas no folclore da região e na literatura de Cordel. Mas, ao lado do messianismo, outro aspecto faz-se notório nos personagens de Suassuna: a crueldade. E este tema, bem como o nome do personagem D. Pedro Dinis Quaderna, remete-nos para a história de alguns reis ibéricos da Idade Média: Pedro de Portugal e Pedro de Castela, que serão revisitados à luz da Crônica de D. Pedro de Fernão Lopes, no intuito de observar-se o diálogo com esta estabelecido por Suassuna, direta ou indiretamente

The Pindaric poetry of Cruz e Silva and the Neoclassical revival among Lusitanian national heroes

António Dinis da Cruz e Silva, member of Arcádia Lusitana, the literary academy he helped to found, introduced the Pindaric ode to the Portuguese literature of the neoclassical period (18th century). This poet imitates the triadic form and the mythological nature of Pindar’s encomiastic poetry, in order to celebrate the deeds of reputed historical figures from the national context, such as sailors, captains, politicians, and even the king himself. As in Pindar’s poetry, the mythological excursus holds an important part in Cruz e Silva’s Pindaric poetry. Winners of athletic games are acclaimed through allusion to the ancient heroes. Likewise, the heroes of the Portuguese history see themselves turned into immortals, since their deeds are reported as comparatively greater than those of Homeric warriors. Among the 44 Cruz e Silva’s Pindaric odes, 18 rewrite the myth of the Trojan War, from its beginnings with Eris (Odes I-II) to its outcome with the imperishable fame of the most conspicuous Homeric fighters (Ode XLII). These 18 compositions (re)tell, in a neoclassical style, the main scenes and themes of the Iliad and Odyssey, alluding directly to their heroes’ deeds. Achilles’ wrath and Hector’s death are topics repeatedly brought up in Cruz e Silva’s Pindaric poetry as models of courage and patriotism for national heroes. This chapter offers a discussion of Cruz e Silva’s neoclassical representation of the Trojan War. To this effect, an interdisciplinary approach is adopted, showing how the Portuguese poet handles the mythological material from Homer and Pindar. In this way, he initiated in 18th-century Portuguese literature a new literary genre, the Pindaric ode. By dealing with Poetry and History, Cruz e Silva perpetuated the life and fame of national heroes long after their deaths.

Damage evaluation of drilled carbon/epoxy laminates based on area assessment methods

The characteristics of carbon fibre reinforced laminates had widened their use, from aerospace to domestic appliances. A common characteristic is the need of drilling for assembly purposes. It is known that a drilling process that reduces the drill thrust force can decrease the risk of delamination. In this work, delamination assessment methods based on radiographic data are compared and correlated with mechanical test results (bearing test).

Décombres de l’avenir et projets rudéraux : les métamorphoses de Paris chez Verne, Hugo et Zola

Entre 1853 et 1870, de multiples quartiers de la ville sont éventrés pour permettre la mise en place de nouveaux boulevards par le baron Haussmann, préfet de Paris sous Napoléon III. Ces travaux majeurs ont frappé l’imaginaire social et constitué un objet de fascination pour la littérature. Le mémoire se situe sur le terrain de la sociocritique. La chercheuse cherche à comprendre comment des textes de Verne, Hugo et Zola lisent la nouvelle configuration urbaine parisienne. Dans Paris au XXe siècle (1863), Jules Verne projette la destruction dans le futur et, en retour, imagine les rémanences d’un passé étrangement constructif. Bien qu’il soit en exil, Victor Hugo est très au courant des changements urbains et sociaux en cours. Dans Paris (1867), son écriture travaille à rendre compatibles les idées de ruine et de progrès. Émile Zola, avec Paris (1898), exprime les contradictions accompagnant le changement urbain par le biais de métaphores médicales et organiques proches de « l’esprit de décadence » qui caractérise la fin du siècle. En conformité avec les visées de l’approche sociocritique, c’est à partir d’une lecture interne des oeuvres, mettant à profit les ressources de l’analyse de texte, de la poétique et de la narratologie, que la recherche se développe. L’étude mobilise également les ressources des travaux consacrés aux relations de la littérature et de la ville, ainsi que celles des ouvrages de synthèse produits dans les champs de l’histoire générale et de l’histoire de l’urbanisme.

Fast automatic microstructural segmentation of ferrous alloy samples using optimum-path forest

In this work we propose a novel automatic cast iron segmentation approach based on the Optimum-Path Forest classifier (OPF). Microscopic images from nodular, gray and malleable cast irons are segmented using OPF, and Support Vector Machines (SVM) with Radial Basis Function and SVM without kernel mapping. Results show accurate and fast segmented images, in which OPF outperformed SVMs. Our work is the first into applying OPF for automatic cast iron segmentation. © 2010 Springer-Verlag.

Computer techniques towards the automatic characterization of graphite particles in metallographic images of industrial materials

The automatic characterization of particles in metallographic images has been paramount, mainly because of the importance of quantifying such microstructures in order to assess the mechanical properties of materials common used in industry. This automated characterization may avoid problems related with fatigue and possible measurement errors. In this paper, computer techniques are used and assessed towards the accomplishment of this crucial industrial goal in an efficient and robust manner. Hence, the use of the most actively pursued machine learning classification techniques. In particularity, Support Vector Machine, Bayesian and Optimum-Path Forest based classifiers, and also the Otsu's method, which is commonly used in computer imaging to binarize automatically simply images and used here to demonstrated the need for more complex methods, are evaluated in the characterization of graphite particles in metallographic images. The statistical based analysis performed confirmed that these computer techniques are efficient solutions to accomplish the aimed characterization. Additionally, the Optimum-Path Forest based classifier demonstrated an overall superior performance, both in terms of accuracy and speed. © 2012 Elsevier Ltd. All rights reserved.

Biomass-to-bio-products application of feruloyl esterase from Aspergillus clavatus

The structural polysaccharides contained in plant cell walls have been pointed to as a promising renewable alternative to petroleum and natural gas. Ferulic acid is a ubiquitous component of plant polysaccharides, which is found in either monomeric or dimeric forms and is covalently linked to arabinosyl residues. Ferulic acid has several commercial applications in food and pharmaceutical industries. The study herein introduces a novel feruloyl esterase from Aspergillus clavatus (AcFAE). Along with a comprehensive functional and biophysical characterization, the low-resolution structure of this enzyme was also determined by small-angle X-ray scattering. In addition, we described the production of phenolic compounds with antioxidant capacity from wheat arabinoxylan and sugarcane bagasse using AcFAE. The ability to specifically cleave ester linkages in hemicellulose is useful in several biotechnological applications, including improved accessibility to lignocellulosic enzymes for biofuel production. © 2012 Springer-Verlag Berlin Heidelberg.

Biocompatibility of a porous alumina ceramic scaffold coated with hydroxyapatite and bioglass

This study aimed to evaluate the osteointegration and genotoxic potential of a bioactive scaffold, composed of alumina and coated with hydroxyapatite and bioglass, after their implantation in tibias of rats. For this purpose, Wistar rats underwent surgery to induce a tibial bone defect, which was filled with the bioactive scaffolds. Histology analysis (descriptive and morphometry) of the bone tissue and the single-cell gel assay (comet) in multiple organs (blood, liver, and kidney) were used to reach this aim after a period of 30, 60, 90, and 180 days of material implantation. The main findings showed that the incorporation of hydroxyapatite and bioglass in the alumina scaffolds produced a suitable environment for bone ingrowth in the tibial defects and did not demonstrate any genotoxicity in the organs evaluated in all experimental periods. These results clearly indicate that the bioactive scaffolds used in this study present osteogenic potential and still exhibit local and systemic biocompatibility. These findings are promising once they convey important information about the behavior of this novel biomaterial in biological system and highlight its possible clinical application. © 2013 Wiley Periodicals, Inc.

New isoflavones from the leaves of Vatairea guianensis Aublé

Das folhas de Vatairea guianensis Aublé foram isoladas quatro isoflavonas identificadas como, 5,3',-diidroxi-4'-metoxi-2",2"-dimetilpirano-(5",6":8,7)-isoflavona ( 1: ), 5,7-diidroxi-3',4'-metilenodioxi-8-prenil-isoflavona ( 2: ) e 5,3'-diidroxi-4'-metoxi-7-O-β-glicopiranosídeo-8-prenil-isoflavona ( 3: ) e derrona ( 4: ), juntamente com cinco triterpenos identificados em mistura de lupeol, α-amirina, β-amirina, germanicol e ácido betulínico. As substâncias 1: 3: são novos produtos naturais, porém 1: e 2: já foram citados como produtos de síntese. No entanto, todas essas substâncias são relatadas pela primeira vez para essa espécie. Suas estruturas químicas foram elucidadas com base nos seus dados de ressonância magnética nuclear (RMN) 1D e 2D e por espectrometria de massas de alta resolução. O extrato etanólico das folhas e os compostos 1-3: foram avaliados quanto ao seu potencial sequestrador do radical DPPH• (2,2-difenil-1-picril-hidrazila) e os resultados mostram que o extrato apresentou alta atividade (CI₅₀ = 6,2 ± 0,4 µg mL^-1), enquanto as substâncias testadas apresentaram baixo poder antioxidante (CI₅₀ ≥ 29,5 ± 2,5 µg mL^-1) quando comparadas com TROLOX (CI₅₀ = 4,5 ± 0,4 µg mL^-1).

A path- and label-cost propagation approach to speedup the training of the optimum-path forest classifier

In general, pattern recognition techniques require a high computational burden for learning the discriminating functions that are responsible to separate samples from distinct classes. As such, there are several studies that make effort to employ machine learning algorithms in the context of big data classification problems. The research on this area ranges from Graphics Processing Units-based implementations to mathematical optimizations, being the main drawback of the former approaches to be dependent on the graphic video card. Here, we propose an architecture-independent optimization approach for the optimum-path forest (OPF) classifier, that is designed using a theoretical formulation that relates the minimum spanning tree with the minimum spanning forest generated by the OPF over the training dataset. The experiments have shown that the approach proposed can be faster than the traditional one in five public datasets, being also as accurate as the original OPF. (C) 2014 Elsevier B. V.
