Avalia����o do m��todo de classifica����o baseada no objeto em imagens de alta resolu����o espacial aplicado para o monitoramento de faixa de dutos: estudo de caso no entorno da refinaria de Capuava em Mau�� - SP

The metropolitan region of S��o Paulo is the most populous of the country, this happens because of its great importance in the national economy and the job opportunities that are offered to the population. These factors result in intense population growth and urban expansion, reaching some non-habitable places of the metropolis, as areas of pipelines, which are very important for the transportation of natural gas, oil and its derivatives. Before the population growth of the region, these sites were unoccupied, do not presenting problems for the population. However, with the disorderly occupation is generated great anthropogenic pressure on the pipeline stitches, causing risks to people who are around them. Therefore it is extremely important to monitor the strip of pipelines through products and techniques of remote sensing and geoprocessing, enabling, through high spatial resolution images, identification of objects or phenomena that occur on Earth's surface that can alter the functioning and safety of pipelines. Therefore, this study aims to monitor a stretch of the area of the pipeline mesh GASPAL/OSVAT and Capuava Refinery (RECAP), located on the outskirts of the metropolitan area of S��o Paulo in the city of Mau��, who suffer great human pressure, proving thus the techniques of remote sensing and geographic information system (GIS) as effective tools for monitoring phenomena occurred in urban areas of great complexity. The monitoring was done by object-based classification applied in orbital images Ikonos II and RapidEye, of high spatial resolution and, image processing, detection of objects, segmentation, classification and editing were developed through the eCognition and ArcGis softwares. To determine the statistical accuracy of the mapping of the land cover of the stretch of pipeline in Maua, the results were analyzed by error matrix...

Cryptotermes brevis (Isoptera, Kalotermitidae): biologia e polimorfismo de imaturos

Cryptotermes brevis (Walker, 1853) �� um cupim de madeira seca ex��tico no Brasil, pertencente a fam��lia Kalotermitidae e que possui uma distribui����o geogr��fica bastante ampla, sendo encontrada somente em ambientes sinantr��picos. Esta esp��cie de cupim de madeira seca vive dentro de peda��os de madeira onde escava suas galerias por meio da alimenta����o. Estes insetos se alimentam do pr��prio ninho onde vivem e sua infesta����o �� percebida pela forma����o de gr��nulos fecais s��lidos que s��o expulsos de pe��as de madeira infestadas. Dessa forma, C. brevis causa grandes danos econ��micos em ��reas urbanas, infestando pe��as de mobili��rios manufaturados pelo homem e estruturas de madeira como batentes, forros, rodap��s, etc. Em uma col��nia de cupins de madeira seca existem castas morfofisiologicamente diferentes, as quais realizam tarefas distintas. Entre elas est��o as castas ��pteras (soldados e falsos oper��rios), e os reprodutores (rei e rainha). A maioria das castas de cupins s��o cegas e exibem comportamentos caracter��sticos que s��o utilizados na comunica����o entre eles, como por exemplo trofalaxia estomodeal e proctodeal, ���grooming���, antena����o, ���butting���, etc. Devido ao reduzido conhecimento da biologia dessa importante praga urbana, o presente trabalho objetivou elucidar as aspectos da biologia e do polimorfismo de imaturos nesta esp��cie de cupim. Para entender o polimorfismo de larvas e ninfas foi realizado um estudo biom��trico em que mensurou-se a largura da cabe��a e do pronoto e o comprimento do broto alar e da t��bia. Os resultados obtidos mostraram tr��s ��nstares larvais e quatro ��nstares ninfas. Adicionalmente, foram iniciadas col��nias que foram abrigadas em diferentes volumes (300 cm3 e 150 cm3) e tipos de madeira. Estas col��nias incipientes de laborat��rio foram abertas ap��s seis meses e mostraram uma m��dia de 5 indiv��duos por col��nia... (Resumo completo, clicar acesso eletr��nico abaixo)

Telejornalismo na era digital: interatividade e acesso �� informa����o

Este trabalho de Conclus��o de Curso teve por finalidade investigar quais recursos interativos estar��o dispon��veis para o telejornalismo com a chegada da televis��o digital e como esses recursos poder��o ser usados como instrumentos para a amplia����o do acesso �� informa����o jornal��stica. Para tanto, foi feita uma reflex��o sobre a produ����o de sentido e a pr��tica discursiva, com ��nfase nas altera����es nos enunciados telejornal��sticos no contexto da converg��ncia midi��tica. Foram analisados dois telejornais, o ���Jornal Globo News��� e o ���Jornal Hoje���, ambos da rede Globo. O referencial te��rico-metodol��gico utilizado na leitura dos telejornais foi o da semi��tica discursiva de linha francesa, com ��nfase nas estrat��gias enunciativas dos conte��dos interativos, por considerar que estes referenciais sustentam o estudo dos processos de produ����o de sentido. O ���Jornal Hoje��� foi analisado enquanto produto que prop��e nos conte��dos apresentados introduzir novas formas de rela����o de comunica����o, privilegiando a perspectiva de interatividade por parte dos telespectadores. Isso porque os conte��dos remetem a audi��ncia a interferir por meio de outra m��dia, notadamente o computador, acessando o site do telejornal para poder participar. Assim, observa-se que se o conte��do j�� se manifesta convergente, os suportes ainda n��o est��o integrados, pelo menos nessa fase de transi����o. O ���Jornal Globo News��� foi analisado enquanto representante de um telejornal produzido e veiculado j�� na plataforma digital, o que n��o significa que possa ser considerado de imediato interativo. Foram ainda realizadas entrevistas com especialistas e pesquisadores da ��rea tem��tica da pesquisa, que contribu��ram para o amadurecimento e crescimento da mesma. Por meio da an��lise dos objetos foi poss��vel elaborar o ���QUADRO DAS POTENCIALIDADES���, com os recursos interativos que poder��o... (Resumo completo, clicar acesso eletr��nico abaixo)

Agricultura familiar em Rio Claro - SP: em busca de alternativas para perman��ncia no campo

As we focusing in the Brazilian rural area we see that it presents the spatial diversity and the different organization forms of the space arising from its diversity, tied to the different economic, social, politic and cultural contexts .These contextual diversities bring results that is not limited to the agrarian sector, but get beyond the border of the rural world, taking different ways of organization and structuring in the urban areas. The building and management of the rural spaces are constituted as an attribute of the agricultural production that in the course of the centuries made disappear and reduce significant proportions from the natural areas. In many places, the intensification of the production process gives satisfaction to the globalized markets and that return allows the reproduction of the productive conditions. In other areas the access difficulties to the market and the proximity to the developed urban centers cause the abandonment of the agricultural activity and the maintenance of property without production or with specific services (tourism, for example). That process triggers a multiplicity of factors that are defining the pace of the rural areas in Brazil. This work sought to understand all the deals of the ������rural������ county of Rio Claro-SP and what���s the role and the situation that we find the familiar agriculture in the advanced urban areas, which is the case of this study. Where the agriculture doesn���t represent the flagship of the economy. It was the intention, identify what activities and practices socio-spatial are developed in the county rural area. Trying to understand the public politics acts in the promotion and encouragement to the already developed activities or even other activities that can represent the possibility of a social and territorial reproduction of the families on the country

Identifica����o de genes candidatos ao desenvolvimento de Leiomiomas Uterinos

Uterine leiomyomas (UL) are benign smooth muscle tumors from myometrium, representing the major indication for hysterectomies and a significant public health problem. Several genetics alterations have been associated with its development and pathogenesis. Although the initial factors that lead to the development of uterine leiomyomas are unclear, there are several evidences showing that ovarian steroids, estrogen and progesterone, are associated with these tumors.Recent reports, however, show others genes related with distinct signalization pathways besides sex hormones, which may be or not activated by these hormones, are associated with uterine leiomyomas development. In this study, the AHR, ESR1, ESR2, PGR and WNT7A gene transcripts expression was evaluated using quantitative real time RT-PCR in 58 UL samples compared to five normal myometrium tissues to explore the hormonal molecular basis of these tumors and associate these expression pattern with clinical and pathological features. The present study showed AHR, ESR1, ESR2, PGR and WNT7A down expression in 60%, 43%, 52%, 60% e 40% of the tumors, respectively, and a significant AHR loss of expression compared with the controls samples (P=0.0130). The comparison between the genes expression values revealed a positive correlation between the AHR and ESR1 transcripts (P<0.0001; r=0.6911) and between the genes ESR1 and WNT7A (P<0.0001; r=0.5655). The expression pattern was compared with clinical and pathological features. The WNT7A gene presented a differential expression pattern between the proliferative and secretory phase of menstrual cycle (P=0.0373) and the AHR and ESR1 genes were differentially expressed between women in reproductive and menopause years (P=0.0267; P=0.0415, respectively). The ESR1 and WNT7A down regulation was statistically ...(Complete abstract click electronic access below)

Contagem automatizada de ve��culos utilizando segmenta����o estat��stica

In this work was developed a program capable of performing automatic counting of vehicles on roads. The problem of counting vehicles is using expensive techniques for its realization, techniques which often involve manual counting or degradation of the pavement. The main motivation for this work was the importance that the vehicle counting represents to the Traffic Engineer, being essential to analyze the performance of the roads, allowing to measure the need for installation of traffic lights, roundabouts, access ways, among other means capable of ensuring a continuous flow and safe for vehicles. The main objective of this work was to apply a statistical segmentation technique recently developed, based on a nonparametric linear regression model, to solve the segmentation problem of the program counter. The development program was based on the creation of three major modules, one for the segmentation, another for the tracking and another for the recognition. For the development of the segmentation module, it was applied a statistical technique combined with the segmentation by background difference, in order to optimize the process. The tracking module was developed based on the use of Kalman filters and application of simple concepts of analytical geometry. To develop the recognition module, it was used Fourier descriptors and a neural network multilayer perceptron, trained by backpropagation. Besides the development of the modules, it was also developed a control logic capable of performing the interconnection among the modules, mainly based on a data structure called state. The analysis of the results was applied to the program counter and its component modules, and the individual analysis served as a means to establish the par ameter values of techniques used. The find result was positive, since the statistical segmentation technique proved to be very useful and the developed program was able to count the vehicles belonging to the three goal..

Os Efeitos dos Programas Microbacias II: Acesso ao Mercado e Territ��rios da Cidadania no Pontal do Paranapanema ��� SP

A pesquisa tem como objetivo analisar os resultados da implementa����o de duas pol��ticas p��blicas: O Projeto de Desenvolvimento Rural Sustent��vel ��� PDRS (Microbacias II) e o Programa Territ��rios da Cidadania - PTC, sendo que a primeira �� de ��mbito estadual e visa o desenvolvimento rural e a segunda da esfera federal e tem como objetivo promover o desenvolvimento territorial. Optamos por efetuar a aprecia����o emp��rica de ambas as pol��ticas no Escrit��rio de Desenvolvimento Rural (EDR) de Presidente Venceslau, o qual �� composto por onze munic��pios, quais sejam: Caiu��, Euclides da Cunha Paulista, Marab�� Paulista, Mirante do Paranapanema, Piquerobi, Presidente Epit��cio, Presidente Venceslau, Ribeir��o dos ��ndios, Rosana, Santo Anast��cio e Teodoro Sampaio. O Microbacias II (com execu����o prevista entre 2010 a 2015) �� continua����o do Programa Estadual de Microbacias Hidrogr��ficas ��� PEMH (Microbacias I), o qual sua execu����o foi de 2000 a 2008. Ambos obtiveram financiamento parcial do Banco Mundial (BIRD) e se inserem numa nova l��gica de desenvolvimento rural, diferente da que ocorreu entre as d��cadas de 1960 a 1980. Nessa nova perspectiva, passou a haver maior preocupa����o com a degrada����o ambiental e com a pobreza dos agricultores familiares. O Microbacias I teve maior preocupa����o com a degrada����o ambiental, enquanto que o Microbacias II est�� voltado para favorecer a inser����o dos produtores rurais no mercado. O Programa Territ��rios da Cidadania foi criado em 2008 e tem como meta principal combater a pobreza nos territ��rios rurais selecionados. Houve significativos benef��cios de ambos os programas no EDR
