Utilização de técnicas de geoprocessamento para monitoramento de atividades de mineração ao longo de dutos: poliduto Rio de Janeiro/Minas Gerais

The transportation of oil through polyducts implies a concern related to safety and environmental impacts they may cause, especially when exposed to risks that affect their integrity. Among the various anthropogenic activities included in this scenario, mining can aggravate, increase the risks and degrade the environment. Since these polyducts go through significant extensions, remote sensing has great applicability as a tool for data acquisition. For this, change detection techniques were used to monitor mining activities in a defined study area in the state of Rio de Janeiro, along the duct ORBEL. The characterization of the study area and the mining activities were developed through bibliographical data. The satellite images processing and the application of change detection technique were performed in two scenes for the years 2002 and 2010. The growth in the mining area was about 6.67 times and it was possible to identify types of extraction involved which can represent direct risks to the pipeline

Análise dosimétrica de aplicadores de Betaterapia

Betatherapy is a special medical technique using a radioactive source of strontium-90 for the treatment of superficial lesions, especially in dermatology and ophthalmology. Strontium-90 sources emit β radiation, which possesses high ionization power, but a very short distance propagation into matter. This work presents a method of dosimetric analysis of betatherapy using strontium- 90-based instrumentation, commonly used against superficial diseases, such as keloid and pterygium, aiming the description of the dosimetry analysis procedures, which can be easily implemented on tradiotherapy services that offers the betatherapy treatment. IBF-MEDIX radiographic films (conventional films) were exposed to betatherapy applicators during different time intervals according to the activity of the source, and afterwards the optical densities (O. D.) of the radiographic images were measured using an optical densitometer MACBETH. Therefore, the parameters used to make the dosimetric analysis in betatherapy were standardized, as the exposure time depended on the geometry and size of the source, providing an efficient and fast method of dosimetric analysis of the betatherapy equipment of the services, the majority of which do not have the scientific structure to perform this study

Intertextualidades, símbolos e mitos entre o romance Mygale e o filme A pele que habito

The award-winning and controversial movie by Pedro Almodóvar “The skin I live” (2011) is an adaptation of Mygale’s novel (1984), the French writer Thierry Jonquet (1954-2009), translated into Portuguese in 2005 as Tarântula. It is a horror story, full of suspense, in which a renowned surgeon, Robert Ledgard, played by Antonio Banderas, switches, without any scruples, the sex of the young Vincent. What it shown to the viewer since the first images of the movie is, therefore, Vicente/Vera in her new and perfect female body. Flashbacks clarify during the movie the events that culminated in the opening scene that is presented to us, surprising us and, of course, shocking us. References to myths and symbols can be noticed in the movie. They bring with them, to be recognized by the viewer, issues related to the creation or metamorphosis, among others, as the Pygmalion and Galatea myth, which binds to artistic creation. Artistic metamorphosis operated equally by the filmmaker in his modern version of the doctor and the monster, for example, but, especially, in the rereading of the Jonquet’s novel. This study seeks to highlight some of the major myths and symbols inserted in Almódovar’s movie and what interpretations such insertions may ensue.

Figuras fulgurantes: a geometrização do espaço Llansol

Os pregos na erva (1962), the first book by Maria Gabriela Llansol, presents us several textures and pictures that break the dividing lines of both textual and imaging spaces due to the figurative compositional process that stands within the literary universe, coloring it with words. The short stories found in this book are based on minimum action that silences the voices of the characters, expanding some other composition, a new course, not in the order of the narrative continuum, but of the textual one. The three short stories to be analyzed (“Intróito”, “A casa às avessas” e “A manhã morta”) are highlighted due to the meaningful incidence of poetic colors that set representation and the motionless universe of narrative on the move, due to the dialogue established with painting, especially with the pictures by Amadeo Modigliani (“Young Brunette”) and Picasso (“Child holding a dove”). Thus, the lines of writing and the geometric ones of painting cross with each other and draft triangles and circles, being responsible for figures that go beyond figurative language and, by doing so, making the suggested images of textuality’s “fulgor” stronger.

Estudo da fadiga em liga de alumínio aeronáutico 7475-T761

This work will address the study of fatigue conditions with constant load in an alloy of aluminum analysis 7475 - T761, so we can better understand the conditions of the aircrafts which contain this alloy in their structures. A literature review, which was discussed the concepts of fracture mechanics, fatigue, aeronautical components, chemical analysis of aluminum alloys, fatigue problems that appears in the aircrafts, metallographic analysis, and testing of optical microscopy tensile, fatigue and microhardness, surface analysis (MEV) study of the chemical composition of the alloy in question, the main causes of crashes, was performed, completing the work, analysis of data from tensile test, hardness and fatigue together with the interpretation of images of optical microscopy and scanning electron was taken. The data indicated the high mechanical strength of the alloy, along with its microstructure indicating elongated grains and high surface contour, which shows such resistance by hindering the movement of dislocations. The grooves are clearly shown in the MEV images as well as the classic with increased fatigue loading and subsequent reduction of the number of cycles to rupture behavior shown in the graphs. Therefore we observed the optimal behavior is supported by the league when subjected to fatigue loadings

Estudo da superfície do carbono vítreo reticulado após tratamento de implantação iônica por imersão em plasma (3IP) para a obtenção de eletrodos

In this work, RVC samples were treated by plasma immersion ion implantation (PIII) for electrodes production. High-voltage pulses with amplitudes of -3.0 kV or -10.0 kV were applied to the RVC samples while the treatment time was 10, 20 and 30 minutes. Nitrogen, atmospheric air and H2:N2 mixture were employed as plasma sources. The samples were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and electrochemical measurements. The SEM images present an apparent enhancement of the surface roughness after the treatment probably due to the surface sputtering during the PIII process. This observation is in agreement with the specific electrochemical surface area (SESA) of RVC electrodes. An increase was observed of the SESA values for the PIII treated samples compared to the untreated specimen. Some oxygen and nitrogen containing groups were introduced on the RVC surface after the PIII treatment. Both plasma-induced process: the surface roughening and the introduction of the polar species on the RVC surface are beneficial for the RVC electrodes application

Preparação de nanofio via deposição eletroquímica utilizando modelo de membrana porosa

From the last decade of the twentieth century, the rapid growth of nanotechnology has resulted in the discovery of a number of forms of nanoparticles and nanoclusters. We can cite as an example: nanotubes, nanowires, nanobelts, and nanoconesnanoclusters which have a wide range of applications, particularly as catalysts magnetic material nanodevices, chemical sensors, degradation of toxic chemicals, or even as possible carriers for the isotope medical applications.. The first step is the production and characterization of nanowires multithreaded using different types of metals (nickel, silver, gold) and polymers (pyrrole), which are prepared by electrochemical deposition process. Will be held by the characterization of the same images of scanning electron microscopy (SEM) and transmission electron microscopy (TEM)

Pérola gera arte: (re)ações entre gêneros

This paper is part of a larger project. The purpose of this paper is to discuss the movie Girl With a Pearl Earring (2003) by Peter Webber using the theoretical perspective of dialogue from the Bakhtin Circle, Medved, Volochinov. The multidisciplinary and interartistic potential of cinema is considered in this paper when the linguistic organization and the translinguistic elements in the corpus are focused on and understood as an example of cinema genre as discussed in the Russian Circle. The study of the ways of incorporation of different genericities by cinema, illustrated by the dialogues between the pictorial genre, the novel and the movies contribute to the recognition of the cinema as a genre that is composed by the incorporation of other genres. The construction of the cinematographic work in analysis will be regarded in its architectonic (form, content and style) and in the activity field in which it circulates.
