This monograph addresses to the study of Latin metrical notions and concepts as showed in the volume VI of Heinrich Keil’s work, entitled Grammatici Latini (GL): Scriptores Artis Metricae. From that book, it was chosen Terentianus Maurus’s work for corpus, particularly the excerpt between verses 997 and 1299 of De Syllabis, a part of Terentianus’s De Litteris, De Syllabis, De Metris, which is a metric manual written in verses. Until now, there are only three translations of that text into modern languages: two in Italian (one of them was used for comparison with the translation prepared for this monograph) and a French one. That work still contains many reference notes whenever Terentianus Maurus uses ancient authors to demonstrate his explanations on Metrics. Thus this research intends to join in other analysis made on Latin metrical manuals that have already been translated or are still going to be, as well as to notice the importance and the specific value of meter in ancient poetry

O trabalho foi conduzido na UNESP, Jaboticabal-SP, de setembro/2003 a janeiro/2004, com objetivo de avaliar a viabilidade da consorciação de pimentão com as culturas de repolho, rúcula, alface e rabanete. O experimento constou de 15 tratamentos, correspondentes a 10 cultivos consorciados (combinações das cinco hortaliças) e cinco monocultivos. Utilizou-se o delineamento experimental em blocos casualizados, com seis repetições. Foram utilizados os híbridos Magali R e Kenzan, respectivamente, para pimentão e repolho; e as cultivares Vera, Cultivada e Crimson Gigante, respectivamente, para alface, rúcula e rabanete. As produtividades de pimentão e repolho em cultivo consorciado não diferiram significativamente das obtidas em monocultivo. Maior massa fresca de parte aérea de plantas de alface (438,86 g/planta) foi observada quando a alface foi consorciada com pimentão, diferindo estatisticamente dos demais cultivos que obtiveram em média 323,05 g/planta de alface. Aumento na produtividade de raízes comerciais de rabanete foi observado quando consorciado com pimentão, porém, foi significativamente superior apenas ao cultivo consorciado de pimentão+repolho+rabanete. A massa fresca da parte aérea da rúcula mostrou diferença estatística apenas entre os consórcios de pimentão+rúcula+alface e pimentão+repolho+rúcula. Exceto o consórcio pimentão+repolho que obteve índice de uso eficiente da terra (UET) de 1,92; todos os outros consórcios apresentaram UET superior a 2,0, com maior UET (2,64) obtido no consórcio pimentão+alface. A superioridade de 92 a 164% na produção de alimento por área dos consórcios sobre os monocultivos, demonstra a viabilidade dos policultivos e maior eficiência do uso da terra.

Com o objetivo de estudar a relação entre doses de calcário e produção de carambolas, um experimento de campo foi conduzido em um Latossolo Vermelho distrófico, no município de Bebedouro(SP), no período de 1999 a 2006. O delineamento adotado foi o em blocos casualizados, com cinco tratamentos e quatro repetições. O calcário foi aplicado uma única vez em 1999, nas doses de: 0; 1,85; 3,71; 5,56 e 7,41 t ha-1. A produção das caramboleiras aumentou em resposta à aplicação do corretivo de acidez. As produções acumuladas de frutos, nos anos sucessivos de 2003, 2004, 2005 e 2006, estiveram associadas às doses mais econômicas de calcário de 4,5; 4,8; 5,3 e 5,3 t ha-1, respectivamente.

The impact of pollutants in an organism can be observed by changes in functional complexity at different levels. Bivalve gills are suitable for histopathological analysis because of their structure and function. This study aimed at examining the morphology of Mytella falcata gill filaments from three sites in the Santos estuary (São Paulo, Brazil) with different levels of environmental degradation to identify possible changes in gill structure and discuss the significance of these alterations. For this purpose, histological, histochemical and ultrastructural techniques were used. The filaments of animals from site A (less impacted site) were intact, while in sites B and C, pathological changes were observed, such as: detachment of the epithelium in the intermediate zone, morphological changes of this epithelium, inflammatory process, increase in the number of mucous cells and cell turnover processes. These results suggest that the related changes are an attempt to prevent the entrance of pollutants through gill filaments into the entire organism and that cell turnover is the final way to compensate cell injury.

Neste experimento, avaliou-se o efeito de sexo (macho e fêmea) e de quatro distintos pesos de abate (28, 32, 36, e 40 kg) sobre a morfometria da carcaça, os pesos dos cortes, a composição tecidual e os componentes não constituintes da carcaça, em cordeiros mestiços Ile de France x Corriedale, terminados em confinamento. Utilizaram-se 40 animais (20 machos e 20 fêmeas), desmamados aos 60 dias e alimentados, à vontade, com uma ração com 16,46% de PB e 67,63% de NDT. Foram divididos em quatro grupos de machos (G1M, G2M, G3M e G4M), sacrificados, respectivamente, com os pesos supracitados, e, da mesma forma, quatro grupos de fêmeas (G1F, G2F, G3F e G4F). Determinaram-se as medidas da carcaça e, de forma subjetiva, a condição corporal, o grau de conformação e o grau de gordura de cobertura. Calcularam-se os índices de compacidade da carcaça e da perna. Foram registrados os pesos e as porcentagens de sete cortes da meia carcaça, bem como as porcentagens de osso, músculo e tecido adiposo, avaliadas por meio de dissecção do lombo. A espessura da gordura de cobertura foi determinada na região lombar. O estudo morfométrico confirmou maior alongamento ósseo dos machos. de maneira geral, as carcaças apresentaram-se com bom acabamento, segundo os índices de compacidade verificados. Os cortes das carcaças das fêmeas foram mais pesados que os dos machos (exceto para o peso de 28 kg ao abate), principalmente em função dos maiores teores de gordura. Destaca-se a representabilidade dos pesos da pele e do conteúdo gastrintestinal na determinação do rendimento da carcaça. Pelos resultados obtidos, recomenda-se 28 kg como peso referência para sacrifício.

The purpose of this study was to evaluate in vivo the response of the periradicular tissues after endodontic treatment and root filling with Epiphany/Resilon (Penntron Clinical Technologies, LLC, Wallingford, CT) or gutta percha and new Sealapex (SybronEndo, Glendora, CA) in dogs' teeth with or without coronal restoration. Teeth without coronal restorations were used to assess the influence of continuous exposure to the oral environment on the periradicular tissues. Sixty root canals with vital pulps in three dogs were instrumented and obturated in a single session and randomly assigned to one of four groups as follows. group 1: root canal filling with Epiphany/Resilon with coronal restoration, group 2: root canal filling with Sealapex sealer and gutta percha with restoration, group 3: root canal filling with Epiphany/Resilon without restoration, and group 4: root canal filling with Sealapex sealer and gutta percha without coronal restoration. After 90 days, the animals were euthanized, and the maxillas and mandibles were removed and submitted for histologic processing. Longitudinal sections were obtained and stained with hematoxylin and eosin, Mallory's trichrome, and Brown and Brenn stains and examined under light microscopy. There were significant differences found between the four groups (p < 0.05). The results showed that roots canals filled with Epiphany/Resilon, with coronal restoration, had significantly less periradicular inflammation than roots canals filled with gutta percha and Sealapex, with coronal restoration (p = 0.021). No significant difference was observed in the intensity of inflammation between roots canals filled with Epiphany/ Resilon with no restoration and roots filled with gutta percha and Sealapex with restoration (p = 0.269). Roots canals filled with gutta percha and Sealapex sealer without coronal restoration showed the greatest degree of periradicular inflammation.

In order to determine the in vitro digestibility of the dry matter, crude protein and gross energy of caged laying hen manure, an experiment was conducted at the Faculdade de Ciências Agrarias e Veterinarias, campus de Jaboticabal, using completely randomized design with four treatments and six replications. The treatments T1, T2, T3 and T4 consisted of manure stocked for 0, 7, 14 and 21-days, respectively. The in vitro digestibility mean values for T1, T2, T3 and T4 were, respectively, 49.25; 51.43; 49.60 and 46.27% for the dry matter, 60.20; 66.90; 59.40 and 49.21% for the crude protein and 57.30; 63.71; 61.17 and 54.50% for the gross energy. The digestibility regression equations for the dry matter, crude protein and gross energy were, respectively: Y = 49.37 + 0.44X - 0.028X2; Y - 60.77 + 1.23X - 0.086X2 and Y = 57.54 + 1.24X - 0.066X2 were Y = digestibility coefficients and X = stocking times.

The Schwinger-Dyson equations for the nucleon and meson propagators are solved self-consistently in an approximation that goes beyond the Hartree-Fock approximation. The traditional approach consists in solving the nucleon Schwinger-Dyson equation with bare meson propagators and bare meson-nucleon vertices; the corrections to the meson propagators are calculated using the bare nucleon propagator and bare nucleon-meson vertices. It is known that such an approximation scheme produces the appearance of ghost poles in the propagators. In this paper the coupled system of Schwinger-Dyson equations for the nucleon and the meson propagators are solved self-consistently including vertex corrections. The interplay of self-consistency and vertex corrections on the ghosts problem is investigated. It is found that the self-consistency does not affect significantly the spectral properties of the propagators. In particular, it does not affect the appearance of the ghost poles in the propagators.

Biscutulumnemus neotropicus gen. nov., sp. nov. (Tarsonemidae: Tarsoneminae: Tarsonemini) is described from adult female and male mites, collected on Croton floribundus Spreng., from São José do Rio Preto, State of São Paulo, Brazil. This new genus resembles members of Dendmptus and Tarsonemus, but male mites have two triangular shields anterolaterally to the prodorsal shield and the sejugal apodeme is absent. In addition, Biscutulumnemus differs from Dendroptus by the presence of femoral seta l″ and tibial solenidion φ1 and the presence of a vestigial apodeme I on female mites. Unlike Tarsonemus, Biscutulumnemus has a beaklike gnathosomal capsule, a round flange on leg IV of male mites, and stigmata very close to v1 on the prodorsal shield of female mites.

In Lead-cadmium fluorogermanate glasses (PbF2-CdF 2-PbGeO3) the addition of metal fluorides to the base PbGeO3 glass leads to a decrease of the glass transition temperature (Tg) and to an enhancement of the ionic conductivity properties. Based on different spectroscopic techniques (19F NMR, Ge K-edge X-ryas absorption and Raman scattering) an heterogeneous glass structure is proposed at the molecular scale, which can be described by fluoride rich regions permeating the metagermanate chains. The temperature dependence of the 19F NMR lineshapes and relaxation times exhibits the qualitative and quantitative features associated with the high fluoride mobility in these systems. Eu 3+ emission and vibronic spectra are used to follow the crystallization process leading to transparent glass ceramics.
