Proposta metodológica para o imageamento digital e modelagem virtual 3d de um bloco de rochas travertinas

In this paper we present the methodological procedures involved in the digital imaging in mesoscale of a block of travertines rock of quaternary age, originating from the city of Acquasanta, located in the Apennines, Italy. This rocky block, called T-Block, was stored in the courtyard of the Laboratório Experimental Petróleo "Kelsen Valente" (LabPetro), of Universidade Estadual de Campinas (UNICAMP), so that from it were performed Scientific studies, mainly for research groups universities and research centers working in brazilian areas of reservoir characterization and 3D digital imaging. The purpose of this work is the development of a Model Solid Digital, from the use of non-invasive techniques of digital 3D imaging of internal and external surfaces of the T-Block. For the imaging of the external surfaces technology has been used LIDAR (Light Detection and Range) and the imaging surface Interior was done using Ground Penetrating Radar (GPR), moreover, profiles were obtained with a Gamma Ray Gamae-spectômetro laptop. The goal of 3D digital imaging involved the identification and parameterization of surface geological and sedimentary facies that could represent heterogeneities depositional mesoscale, based on study of a block rocky with dimensions of approximately 1.60 m x 1.60 m x 2.70 m. The data acquired by means of terrestrial laser scanner made available georeferenced spatial information of the surface of the block (X, Y, Z), and varying the intensity values of the return laser beam and high resolution RGB data (3 mm x 3 mm), total points acquired 28,505,106. This information was used as an aid in the interpretation of radargrams and are ready to be displayed in rooms virtual reality. With the GPR was obtained 15 profiles of 2.3 m and 2 3D grids, each with 24 sections horizontal of 1.3 and 14 m vertical sections of 2.3 m, both the Antenna 900 MHz to about 2600 MHz antenna. Finally, the use of GPR associated with Laser Scanner enabled the identification and 3D mapping of 3 different radarfácies which were correlated with three sedimentary facies as had been defined at the outset. The 6 profiles showed gamma a low amplitude variation in the values of radioactivity. This is likely due to the fact of the sedimentary layers profiled have the same mineralogical composition, being composed by carbonate sediments, with no clay in siliciclastic pellitic layers or other mineral carrier elements radioactive

Zoneamento ambiental do Município de Aquiraz-CE

The Metropolitan Region of Fortaleza (RMF) is composed by thirteen cities, where is call the attention of Aquiraz. The city has a excellent resort area and a big importance in socioculture and historics aspects. It was one of the first village of Ceará, and it was founded in 1699, with was also the capital of the state until 1726. The urban local development has been disorganized in the last decades, the fact is, insert of turismon in its coast, and it is unable with alow capacity of the natural suppots, configuring unsustainable and et environment ambience. Considering as a turistic region, it is preoccupy, been necessart to create a better control of the nature of the region by the users. The environmental zoning in this work it is to plan of adequate form the use of the ground based in the management of the interests and the social and economic necessities in accord with the preservation of the environment and the natural characteristics of the city. The same is one great instrument planning where use to be analized in differents ways: social, ambiental, economical and institucional, and promove alternatives of use and occupation of the land to recreate the city. The methodo used to get the real objective, englobed zonal maps in ambiental unities and others themes (geologic/geomorphologic) since than the images from satelities LANDSAT and SPOT and fotografies under position of maps, secundaries listes gets in publics department, bibliographie, informations by the local populations. This prociduries mede easy to create maps, geologic/geomorphologic, of use and occupation the earth and the environmental zoning to analize the dynamic and the working of each ambiental unity of the city Aquiraz wich is located by map of this job. As a result of this job was confectionated the environmental zoning map of Aquiraz wich was divided in five ambiental unities and restrictions areas of occupation: unit I Littoral Plain (zoning with serious restrictions to the occupation); unit II Sub-Littoral Plain (improper zoning to the occupation); unit III between tray zoning Pré-Littoral and Peripheral Depression (improper zoning to the occupation); unit IV Strativism reserve of the plug (zoning used more under control in its occupation) and unit V Fluvial Plain Localities of the Indians Jenipapo-Kaninde/ locality Quilombolas (zoning used more without official regulation). With proposal in the ambient units above one expects that it has a reduction of the ambient degradation and protection of the local biodiversity of the city of Aquiraz in the State of the Ceará

Um estudo sobre o ensino de evaporação no contexto ciência, tecnologia e sociedade

The scope of this Dissertation is propose the teaching of the evaporation based on the approach Science, Technology and Society (STS) because we believe that this type of approach is able to provide students with a more critical and conscious learning about science. Moreover, with this search, it´s possible to show for students the importance of role to play for them as citizens in decision making aimed to benefit all who are part of the community to which they belong. From this perspective, broached the theme evaporation in a region characterized by constant lack of water for consumption, the municipality of Santa Cruz/RN because, despite the creation of dams to regulate the flow of rivers and increase the availability of water during periods of scarcity, we know that these reservoirs have a large free liquid surface allowing high water loss by evaporation. Thus, evaporation affects the performance of reservoirs for water supply and irrigation, being a phenomenon of particular interest to study. To this end, a questionnaire in order to identify students' preconceptions on the subject was applied. Was then prepared and conducted a workshop geared toward students majoring in Physics Campus Santa Cruz, Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN). The completion of the workshop served as a space for discussion of the topic within the context of the municipality of Santa Cruz/RN. As a product, we suggest to physics teachers a guide with recommendations to be taken into account when they teach this subject

Física do meio ambiente como disciplina nas licenciaturas em física: proposta de uma unidade didática para ensinar efeito estufa e aquecimento global

In this dissertation we propose a Teaching Unit of Physics to teach content through environmental discussions of the greenhouse effect and global warming. This teaching unit is based on a problem-methodological intervention from the application of the method of the Arch of Charles Maguerez. The methodological foundations of the thesis are embedded in action research and this is structured in five chapters: the first chapter deals with the Physical Environment (FMA) as a subject in Degree Courses in Physics in Brazil, bringing the concern of how this discipline has been taught. We started the first chapter explaining the reasons behind the inclusion of the discipline of Physical Environment in a Physics Degree Courses. Then we did a search on the websites of Institutions of Higher Education, to know of the existence or not of this discipline on curricular. We then analyzed the menus to see what bibliographies are being adopted and what content of Physics are being worked, and how it has been done. The courses surveyed were those of Federal and Federal Institutes Universities. Thus ended the first chapter. Given the inseparability between studies in Physics Teaching and studies on competencies, skills and significant learning, wrote the second chapter. In this chapter we discuss the challenge of converting information into knowledge. Initially on initial teacher training, because even if this is not our focus, the study is a discipline on the upper reaches, therefore, offered to future teachers. Then we talked about the culture of knowledge, where we emphasize the use of a teaching approach that promotes meanings taught by content and make sense to the student. We finished the third chapter, making some considerations on skills and abilities, in order to identify what skills and competencies were developed and worked during and after the implementation of Curriculum Unit. The third chapter is the result of a literature review and study of the radioactive EarthSun interaction. The subjects researched approach from the generation of energy in the sun to topics stain solar coronal mass ejections, solar wind, black body radiation, Wien displacement law, Stefan-Boltzmann Law, greenhouse effect and global warming. This chapter deals with material support for the teacher of the aforementioned discipline. The fourth chapter talks about the arc method of Charles Maguerez; Here we explain the structure of each of the five steps of the Arc and how to use them in teaching. We also show another version of this method adapted by Bordenave. In the fifth and final chapter brought a description of how the method of Arc was used in physics classes of Environment, with students majoring in Physics IFRN Campus Santa Cruz. Here, in this chapter, a transcript of classes to show how was the application of a problem-based methodology in the teaching of content proposed for Physics Teaching Unit from the environmental discussion about the greenhouse effect and global warming phenomena

Comportamento geotécnico de misturas de solo e resíduos de perfuração onshore

The drilling of wells for petroleum extraction generates rocks and soils fragments, among other residues. These fragments are denominated petroleum drilling gravel or simply petroleum drilling residue. On the sites of onshore exploration are formed big deposits of drilling gravel, an expensive final destination material. This work aims at evaluating the addition of drilling residue to a lateritic soil, as composite material, for construction of compacted fills for earth work projects. Soil and residue were evaluated by X-ray diffraction (XRD) and X-ray fluorescence (XRF) and by laboratory tests traditionally used in soil mechanics, as particle-size analysis of soils, determination of liquid and plasticity indexes and compaction test. After soil and residue characterization, soil-residue mixtures were studied, using dosages of 2,5%, 5%, 10%, and 15% of residue in relation to the dry soil mass. These mixtures were submitted to compaction test, CBR, direct shear test and consolidation test. The test results were compared to the current legislation of DNIT for compacted fill construction. The results showed that the mixtures presented the minimal necessary parameters, allowing, from the point of view of geotechnical analysis, the use of these mixtures for construction of compacted fills

Movimentos sociais e educação superior: ação coletiva e protagonismo na construção do Plano Nacional de Educação (2014 - 2024)

Este trabajo analizó el protagonismo de los Movimientos Sociales en el proceso de construcción y de aprobación del Plan Nacional de Educación (PNE 2014 - 2014) con énfasis en las metas para da Educación Universitaria. Las cuestiones que problematizan la investigación son: ¿En qué contexto histórico los Movimientos Sociales asumieron el acceso a la educación universitaria com o un derecho social? ¿Qué protagonistas se involucraron en el debate sobre la política de educación universitaria en el PNE (2014 - 2024)? ¿Qué confrontaciones y antagonismos están presentes allí? ¿Cuál es el papel de los Movimientos Sociales en la Conferenc ia Nacional de Educación (CONAE) y en el Foro Nacional de Educación (FNE)? Para contestarlas, articulamos la política educacional propuesta por el PNE con las reivindicaciones históricas de los Movimientos Sociales por el acceso a la educación como un dere cho social, evidenciando el proceso de construcción de las directrices, las metas y las estrategias en los contextos políticos de articulación, proposición y reivindicación en los que se produjo la actuación de los protagonistas para la elaboración y la ap robación de esta política, tanto cuanto los antagonismos identificados. Como aporte teórico/metodológico adoptamos como objeto de estudio empírico los procesos de construcción y aprobación del mencionado PNE dentro de los espacios de participación colectiv a, en la construcción de acuerdos y proposiciones como la Conferencia Nacional de Educación realizada en 2010 en Brasilia/DF, las conferencias municipales, intermunicipales y de los Estados, el Foro Nacional de Educación (FNE) y la Comisión Especial de la Cámara Federal que lo antecedieron. Para el análisis de los documentos y de los testimonios de los protagonistas de los Movimientos Sociales seleccionados como sujetos de la investigación, los guías teóricos y los fundamentos conceptuales fueron la sociolo gía de las ausencias, la sociologías de las emergencias y el procedimiento de traducción propuesto por Boaventura Santos ( 2005; 2006; 2007; 2010), en diálogo con otros guías teóricos, como las nociones de confrontación política y oportunidad política organ izadas por Sidney Tarrow (2009). Partiendo de esa base conceptual, privilegiamos la relación de los Movimientos Sociales con la agenda de la educación brasileña cuando direccionados al PNE, analizada en base a las contribuciones de Germano (2013; 2011; 200 8; 2007; 1982), Dourado (2011; 2010; 2006); Saviani (2014; 2010; 2009; 2007; 2004,), Gohn (2012; 2010; 1997; 1995), Dagnino (1994) y Scherer - Warren (1993), entre los autores que contribuyen con el carácter transdisciplinario de esta investigación. Las cont ribuciones de estos autores propician el entendimiento de la diversidad epistemológica encontrada en las experiencias llevadas adelante en los Movimientos Sociales mediante sus actuaciones en los diversos espacios sociales e institucionales, observando las conquistas obtenidas en la política educacional contenida en el PNE 2014 - 2024, así como la comprensión de la lucha por el reconocimiento social y sus conexiones con los temas emergentes presentes en el debate de la educación nacional. De este modo, el est udio indica elementos que posibilitaron la confirmación de la tesis de que la Política de Educación Universitaria aprobada en el PNE 2014 - 2024 (Ley nº 13.005/2014) representa las resonancias de las movilizaciones y reivindicaciones de los Movimientos Socia les por el acceso a la educación como un derecho social inalienable.

A vida em família: parentesco, relações sociais e estilo de vida entre os calons de Sobral, Ceará

This thesis analyzes the social relations of Cavalcante family of Gypsies who live in the city of Sobral, Ceará; especially as kinship relations are lived in a context marked by tensions and instability. From the domestic core ethnography conducted from January to June 2013, and observing the representations by gypsies around the family term, the goal is to show how these representations are activated to describe forms of solidarity between gypsies. To define themselves in terms of how a "big family", the ciganos to demarcate the non-Roma and prepare themselves for life in society codes that can be changed in the audience and situations. The paper discusses the role of family relationships in the forms of sociability and conflicts, matrimonial strategies, including non-gypsies, work practices, defining a gypsy lifestyle.

Avaliação dos impactos do uso do sistema de gestão hospitalar no Hospital Universitário Onofre Lopes

The object of this study was motivated by the need to know the possible causes of differences in results achieved in the implementation of a Computerised Management System (CMS) in a Federal University Hospital, located in northeastern Brazil, to understand the factors that influenced the results in different groups when was used the same systems implementation methodologies. Considering the implication of managers, health professionals, other professionals involved and the existing organizational structure in the period when implantation occurred, aimed to know the perception of these people about the development of CMS in the deployment process in your group or sector and also in the organization.The methodology used in this study was the content analysis which provides a rich set of methodological tools for evaluating speeches,enabling us to discourse from the unknown analysis and subjectivity, but with scientific rigor, allowing, at the end, to understand the disparity in results in the implementation of CMS.It was used as a research tool, a semi-structured interview, which exploits a qualitative approach, as suggested by the authors. It was used the approach of the episodic interview, to be more narrative about the experiences of the interview participants in their practical experience along the CMS deployment process in the hospital.Were interviewed three groups of professional and a group of managers, all with higher education in their professions and who participated in the entire implementation process from the beginning.It followed the Bardin's methodology (2009) in all the phases of treatment and interpretation of data, where emerged three categories: the "Thought and Knowledge"; the "Practices and Changes"; the "Obtained Results". From the category "Thought and Knowledge"emerged three subcategories: the "Administrative", the "Institutional" and the "IT Knowledge". From the category "Practices and Changes" emerged three subcategories: "Reality Prior to CMS"; "The IT Project and the implementation of CMS" and "Impacts of the CMS Implementation". From the category "Results Obtained" emerged three subcategories: "Benefits Promoted by CMS", "Dissatisfaction Observed" and "Level of Use and Understanding CMS ". It was observed that the lack of integration of the sectors was a determinant problem in the implementation of CMS. The CMS implementation project was not well dimensioned and divulged in the institution. Different models of leaderships and of objectives of the sectors influenced in the course of the CMS implementation process. We can mention that an CMS should be a consolidation of organizational practices tool already institutionalized and of integration amongthe sectors and not supporting to isolated practices and personalistsfrom sectors of the institution.

Análise do comportamento de técnicas de correspondência binocular para imagens em alta definição

This work presents an analysis of the behavior of some algorithms usually available in stereo correspondence literature, with full HD images (1920x1080 pixels) to establish, within the precision dilemma versus runtime applications which these methods can be better used. The images are obtained by a system composed of a stereo camera coupled to a computer via a capture board. The OpenCV library is used for computer vision operations and processing images involved. The algorithms discussed are an overall method of search for matching blocks with the Sum of the Absolute Value of the difference (Sum of Absolute Differences - SAD), a global technique based on cutting energy graph cuts, and a so-called matching technique semi -global. The criteria for analysis are processing time, the consumption of heap memory and the mean absolute error of disparity maps generated.

Aspectos técnico-interpretativos no quarteto de cordas nº 2 de Guerra-Peixe

Technical and interpretative aspects of the String Quartet No. 2 Guerra-Peixe will approach this work of a composer who is considered one of the greatest exponents of Brazilian music of the twentieth century, who developed several strands in his career as a musicologist, performer, composer, arranger radio and cinema, among others. In this work, we will see in the work in question their compositional styles, pointing sources that he has been drinking and offering elements that will subsidize technical and interpretive choices for future interpreters. After the historical context and esthetics, we will make some brief remarks about the terms performance and interpretation, to support the objective of the work, which will be the interpretation of the work. For that purpose, a comparative analysis was performed between recording of important Brazilian quartets, interviews with relevant players on the national scene and trials in rehearsals and recitals, always making a Quartet bridge with other works by the composer. Concomitantly, it was held analysis of handwritten edits by the composer, culminating with its own revised edition.

Avaliação de qualidade da unidade de diálise no Hospital Universitário Onofre Lopes - HUOL

Over the years there has been a broader definition of the term health. At the same time it was found also an evolution of the concept of health care which in turn has led to changes in the approach to delivery of health services and hence in its management. In this regard, currently the nephrology services have been searching for quality technical and social need. In view of these innovations and the quest for quality, it elaborated the general objective: to develop a quality assessment protocol for dialysis service Onofre Lopes University Hospital. It is an intervention project effected through an action research, which consisted of 4 steps. Initially was identified through a literature search in scientific literature, which quality indicators would apply to a dialysis unit being selected as follows: infection rate in hemodialysis access site, microbiological control of water used for hemodialysis and Index User satisfaction. Through critical reflection on the theme researched in the previous step, it was drawn up three data collection instruments, interview form type, applied between the months of October and November 2015. In addition to the information obtained, also made up of the use of information retrieval technique. The results were organized in graphs and tables and analyzed using qualitative and exploratory technical approach. Then a reflective analysis of the data obtained and the diagnosis of reality studied was traced and confronted with the literature was performed. The data produced in this study revealed that the Dialysis Unit of HUOL is much to be desired, considering that some weaknesses have been identified in its structure. Faced with this finding have been proposed, as a contribution and aiming to guide the development of future actions, suggestions for improvement that should be implemented and monitored to be assured overcoming these difficulties, allowing an appropriate organizational restructuring, and resulting in improved service public offered. It was concluded that for hemodialysis treatment results are achieved and positive, it is necessary to have physical structure and adequate infrastructure, multidisciplinary team specialized, trained and in sufficient quantity, well designed processes for professionals to have standards to be followed decreasing the chance to err, and a risk management system to detect and control situations that endanger patient safety.

Modelagem da degradação de fenol em efluentes aquosos através do processo de foto-fenton

Advanced Oxidation Processes (AOP) are techniques involving the formation of hydroxyl radical (HO•) with high organic matter oxidation rate. These processes application in industry have been increasing due to their capacity of degrading recalcitrant substances that cannot be completely removed by traditional processes of effluent treatment. In the present work, phenol degrading by photo-Fenton process based on addition of H2O2, Fe2+ and luminous radiation was studied. An experimental design was developed to analyze the effect of phenol, H2O2 and Fe2+ concentration on the fraction of total organic carbon (TOC) degraded. The experiments were performed in a batch photochemical parabolic reactor with 1.5 L of capacity. Samples of the reactional medium were collected at different reaction times and analyzed in a TOC measurement instrument from Shimadzu (TOC-VWP). The results showed a negative effect of phenol concentration and a positive effect of the two other variables in the TOC degraded fraction. A statistical analysis of the experimental design showed that the hydrogen peroxide concentration was the most influent variable in the TOC degraded fraction at 45 minutes and generated a model with R² = 0.82, which predicted the experimental data with low precision. The Visual Basic for Application (VBA) tool was used to generate a neural networks model and a photochemical database. The aforementioned model presented R² = 0.96 and precisely predicted the response data used for testing. The results found indicate the possible application of the developed tool for industry, mainly for its simplicity, low cost and easy access to the program.
