Fidelidade composicional de assembléias de braquiópodes (Rhynconelliformea) na plataforma e talude continental: implicações paleontológicas e geológicas

This paper deals with the Compositional Fidelity of the brachiopods assemblages, dominated by Bouchardia rosea, on the outer shelf and continental slope along São Paulo State. Samples were obtained during the Revizee-Score-Sul-Benthos program. The sampled stations are in sites as depth as 90 to 600 meters, along the outer continental shelf, the shelf break and the top of continental slope. The fidelity estimates were obtained directly from the comparisons between living biota and dead shells, from the same collecting stations. Data come from 66 sampling stations, and the vast majority of the Bouchardia rosea individuals collected (n=2393) were dead (n = 2342, 97.9%). Only 51 individuals were collected alive. When pooling the data from all collecting stations the dead/live frequency is of 2,1% only. The occurrences of Bouchardia rosea shells in siliciclastic bottoms are reduced and living individuals were not found on this type of bottom, at least during the sampling program. These results suggest low compositional fidelity (live-dead) or high compositional mismatch, pointing to a recent decrease in this specie population. The low compositional fidelity of the Bouchardia rosea assemblages in outer shelf sites may be due to changes in seawater temperature, nutrient availability and population history. All these issues must be investigated in the near future

Influência de contaminante ambiental em tumor de mama em cadela

Mammary cancer is a multifactorial disease that is believed to be caused by genetic and environmental factors. Among the environmental factors, pyrethroids appear to be able to participate in carcinogenesis through several mechanisms, and have been shown to be associated to mammary tumors in canines. In order to investigate the possible rule of pyrethroid on DNA lesion in mammary tissue we compare the comet assay results between mammary tumor bearing dogs with and without pyrethroid associated to the peri mammary adipose tissue or the tumor itself. The pyrethroids presence was assessed by High Performance Liquid Chromatography (HPLC) and the DNA damage was assessed by the comet assay as previously described. Despite of correlation between DNA damage and tumor histologic aggressiveness, association between the severity of DNA damage and different types of mammary carcinoma was not found. Although pyrethroids were present in 22% of tumors and peritumoral adipose tissue, no difference in the degree DNA damage between the exposed and non exposed cells to pyrethroids were found. As future perspectives for this work, our group will evaluate the relationship of pyrethroids presence in tumors with its angiogenic potential. Angiogenesis evaluation will be based on presence of vascular endothelial growth factor (VEGF) in the tumor cells, and microvessel counts

O conto de Rubens Figueiredo em As palavras secretas: conto contemporâneo

We work with the storybook, As Palavras Secretas, written by carioca Rubens Figueiredo. We treat, then, the Brazilian contemporary tale. For we study the writer’s fiction, first we met a critical bibliography about the narrative and a set of diverse texts: reports, articles, press releases, interviews and essays about the author’s work. We discourse characteristics and the compositional elements of each story and noticed that they are full of symbolism and various elements that they are recurrent. Some of these narratives deal with fragmentation of the man who, indeed, is a very striking feature in the actual Brazilian tale. We meet, then, with characters who feel the need to simulate an identity and that, therefore, coexist with a strong inner conflict. Three of the tales include the unlikelihood of that work, and present, therefore, elements that escape from reality. Finally, Rubens Figueiredo, in As Palavras Secretas, presented us narratives rather elongated, unlike what was ordinary in the category of the tale, which it usually consists of a short extension narrative

O discurso publicitário em foco: questões sobre dialogismo e gênero do dicurso

The subject of this research is the publicity discourse, in its configuration as speech genres, according to theoretical-methodological perspective in Bakhtinian Studies. Considering that there are infinite fields of human communication, Bakhtin says that there is also infinity of speech genres. However, according to the author, every sphere of human activity produces, and even requires, certain genres, with theirs thematic, compositional and stylistics aspects defined according to social-ideological values that materialize in that sphere and in the dialogue in which the texts are produced. The objective of this research is to study, according to this theoretical-methodological perspective, a print advertising piece by the Brazilian Federal Government, conveyed in the Língua Portuguesa magazine, with themes concerning the national public education. We analyze how the image of author is built and how the image of the Other is outlined by that author. It is assumed that the gender to which an advertising piece belongs intends to sell a product or idea. One of the specific objectives of this research is to identify what is being sold in the advertising piece that we analyze and what discursive and stylistic resources are utilized to achieve success in what it intends to promote. The results show that the author (in the voice of the Federal Government), while adopting the position of information-holder, also puts himself in the same plane of the reader, where everyone is responsible for the development of education in the country. The advertising piece intends to project a positive image of the Government, and this project of saying is realized, in the analysis, in the compositional aspects of the text as well in the stylistic aspects

Estudo do aumento no diâmetro do corpo de um rebite a ser cravado em furos acima da tolerância de projeto

In this work are discussed the main types of rivets, their characteristics and applicability within the Aeronautical Industry branch. Here are highlighted the solid rivets, showing off its layout, forms and limits of installation, that are required by aviation regulators. The riveting is a popular and simple procedure of fixing and joining two or more parts, and like any other manufacturing process is subject to process deviations that in some situations are beyond the limits of tolerance. One of these deviations is when the hole diameter exceeds the one proposed in project and which is limited by the rule of edge distance. The overall objective here is to study a possible solution to this problem: the installation of a rivet that has his diameter previously increased by compression. Observe the hole filling after riveting, detect the presence of cracks, discover the yield curve of the fasteners and their the crushing limits for failure prediction are tools used to verify this proposal. They demonstrate, at the end of study, the inefficiency of this procedure, with results that go against the safe fixing of parts in a structure

A palavra poética de Arnaldo Antunes

This article reflects on Arnaldo Antunes‟ (AA) poetics. For this purpose, both the contributions of Fontanille and Zilberberg regarding tensivity, as well as some ideas of Tatit regarding song semiotics. The aim is to think about how the dance between enunciation and enunciate is structured in AA within poetical architecture as exemplified here based on the analysis of the poem “Palavra”. The hypothesis is that the tension between the two central nuclei of the poem, metalanguage and erotism, are the essential compositional marc of AA poetical stylistics. The results lead to the reflection that the musical tension is the game that guarantees the movement between the density of the word and the erotic fluidity of the authorial (metalinguistic) act of production.

Disparos: ensaios sobre fotografia de guerra

Once the choices set involved in the selection of compositional techniques of a photography is mediated by ideological universes, this final project aims to analyze the photographic coverage of the World War II presented in the brazilian publication Revista da Semana during the period in which Brazil was part of the conflict (1942 to 1945). We study the different composition techniques used and the different effects of meaning articulated by these techniques. Thus, our goal is to see how the repetitions are articulated and the translations of meaning in photojournalistic composition from its narrative structure, that is, their way of coded organization. For this, we used the analysis methodology proposed by Umberto Eco on the rhetoric of the image, involving the five levels of photography decomposition (ie iconic levels, iconographic, tropological, topic and enthymematic). We will analyze these images from the perspective of the effects of meaning that the composition techniques to engender glimpse which were woven meanings to this event in that specific space, and which were mediated discourses of Brazilian participation in the conflict

Recycling scrap automotive heat shield insulation material

Automotive heat shields are usually composed of two metal sheets enclosing an insulating material with a paper-like texture that contains refractory ceramic particles. This article discusses the results achieved by recycling the scrap automotive insulation that is discarded in landfills, using the same concept as paper recycling. For comparison with the original product, tests of thickness, bulk density, weight loss on ignition, tensile strength, compressibility, and recovery were performed on recycled materials produced in a so-called "manual" process (involving little automation and performed in adapted facilities) without pressing, and pressed once, twice, and four times. Materials recycled in a so-called "industrial" process (in a paper recycling plant) without pressing, and pressed once were also tested. The recycled materials can be considered approved with respect to the main requirement, thermal insulation, since they dissipated the under-hood temperature by more than 300 A degrees C (like the original product). Like the heat insulation tests, the thermogravimetric analysis suggested that the recycled materials showed higher stability than the original product. Thermogravimetric, microscopy, and energy dispersive spectroscopy analyses indicated that the structural and compositional characteristics of the original product were preserved after recycling.

Os álbuns fotojornalísticos online e a construção do acontecimento: atribuições de sentido a partir da composição imagética dos protestos de junho

Given that the choices involved in the selection of compositional techniques in photography are mediated by values, this article aims to analyze the compositional techniques of photographs published by photojournalistic online albums during the protests of June 2013 in Brazil. These albums feature professional and amateur photographs considered "the best" of this event and, interestingly, the chosen photographs have several composition techniques in common. We will examine these images from the perspective of significant effects that these techniques engender with the objective of examining the meanings that were attributed to that event in those albums.
