O estudo foi realizado numa área degradada pertencente ao campus da UNESP em Rio Claro, e teve como objetivo avaliar a eficiência do método de nucleação para recuperação de áreas degradadas do tipo “transposição de galharia” na atração de fauna. As pilhas de galhos podem funcionar como abrigos artificiais, atraindo potenciais dispersores de sementes secundários, o que potencialmente abreviaria o processo de regeneração de um ambiente degradado. O estudo foi feito através do levantamento de pequenos mamíferos por armadilhas de interceptação e queda em quatro parcelas de 2500 m², sendo duas delas com o tratamento (pilhas de galhos), e duas funcionando como controle, e o resultado esperado seria uma maior quantidade de indivíduos capturados e de gêneros taxonômicos nas parcelas com o tratamento. Entretanto, as quantidades totais de indivíduos capturados no bloco das parcelas com tratamento e no bloco das parcelas controle foram, segundo o teste de Mann-Whitman, estatisticamente idênticos. Também a quantidade de gêneros taxonômicos capturados foi igual nos dois blocos. Desta forma, concluímos que o método “transposição de galharia” foi ineficiente neste estudo, da forma como foi empregado, não contribuindo para um aumento na fauna de pequenos roedores e marsupiais. O método pode ter fracassado devido a pequena quantidade de pilhas de galhos utilizados para o tamanho da área, como também pelo recobrimento da área por uma grande quantidade de gramíneas, que podem ter funcionado por si só como abrigo para os animais capturados, além de poderinibir a entrada de outros gêneros de pequenos mamíferos não-voadores. Sugerimos portanto, para o método ser mais eficiente, a colocação de uma maior quantidade de pilhas de galhos do que a utilizada no presente estudo, e elas devem ser maiores. Para ecossistemas que apresentam gramíneas densas e altas... (Resumo completo, clicar acesso eletrônico abaixo)

The metropolitan region of São 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 São Paulo in the city of Mauá, 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...

The purpose of this study was to evaluate the apical sealing ability and the marginal adaptation of five dental materials used in retrofillings or applied to the bevelled root surface. One hundred and forty extracted single rooted human teeth were used, divided into seven groups of twenty each. ln the first, second, third and fourth groups, the teeth were apicoectomized, submitted to cavity preparations and retrofilled with one of the following materiais: zinc free silver amalgam, a dentin bonding system plus composite resin, a glass ionomer cement ora compomer. In the fifth, sixth and seventh groups, the teeth were apicoectomized and capped on the bevelled root surface with one of the following materiais: a dentin bonding system plus composite resin, a glass ionomer cement or a compomer. Two specimens of each experimental group were evaluated for the marginal adaptation using scanning electron microscopy. The remaining 126 specimens were immersed in 2% methylene blue dye, stored for one week at 37ºC and the infiltration was evaluated with a stereomicroscope. The results showed that the glass ionomer cement presented the lowest values of marginal infiltration when used as retrofilling material, with a significant statistical difference when compared with the others tested materials. When used as apical capping, the glass ionomer cement and the compomer were equivalent and significantly better than the dentin bonding system plus composite resin. Using scanning electron microscopy, all the materials showed some slight adjustment problem. ln the retrofilling, the smallest marginal gaps were observed with the compomer and the dentin bonding system plus composite resin, while the largest were observed with the glass ionomer cement and zinc free silver amalgam. ln the apical capping, the smallest marginal gaps were observed with the compomer and the dentin bonding system plus composite resin and ...

There are several researches on evaluation of urban public space, but not all establish a relationship between the configuration of spaces with the thermal environment, ergonomics and environmental behavior of users. To understand this relationship, the aim of this paper is to present the model DEPAN (Design for Permanence and Attractiveness in niches open spaces of conviviality), based on graphical meshes, which were designed to evaluate the influence of design and ergonomics of open public spaces in the human thermal comfort and the ways in which users appropriate the space. Its applicability is demonstrated through a case study conducted in a park in the city of Bauru-SP. To perform this evaluation public space niches were chosen. They were formed by morphological elements and street furniture and defined by their spatial arrangements. The collected data were incorporated into a Geographic Information System (GIS), which allowed the overlay of meshes. The results indicate that the DEPAN model allows the verification of the spatial characteristics, thermal quality and ergonomic design generated by spaces, as well as the evaluation of the influence of these aspects in the way of using the spaces. The model allows the generation of a classification for every niche and set a value for the level of service offered.

The purpose of this research was to present the principles for the implementation of a future water body classification program at the UGRHI-1 (Management Unit of Water Resources-1/São Paulo, Brazil) using qualitative and quantitative water modeling. Our study area was in Campos do Jordão, a city in the state of São Paulo, specifically in the Perdizes river watershed, which is included in the UGRHI-1. The water quality assessment used a modeling mehtodology that can support a future study for the classification of water bodies in the region. The behavior of DO and BOD parameters was assessed in the water quality scenarios, considering the variations of flows, loads, reductions in withdrawals and different efficiencies in sewage treatment. The model used was QUAL2E developed by USEPA (United States Environmental Protection Agency) that received a new graphic interface named QUAL2R model. The reference flows Q7,10, Q95% and Qm used were obtained through the DAEE (Department of Water and Electric Energy) hydrologic regionalization method. It was noted that of the 9 proposed scenarios, only scenario 6 that was predicted in the flow regime Qm with the existence of a treatment system capable of removing 93% of the BOD, in the Perdizes River remained 67.5% of the time in class 2. Scenario 8 predicted a 50% reduction in In scenario 8 a reduction of 50% in the flow captured in CA-04, associated with the efficiency of 93% of BOD removal keeping the river in class 2. In scenario 9 the minimum required efficiency in sewage treatment in the flow regime Q95% for keeping the river in class 2 was also calculated and the value of 94.7% was obtained.

Problemas com pose e iluminação são desafios complexos para o reconhecimento de faces 2D. Devido a estes problemas vários métodos para reconhecimento de faces 3D têm sido propostos, principalmente pelo fato que os dados em 3D são mais resistentes a iluminação e são úteis para correção de pose. O maior problema com a utilização de métodos 3D é o custo elevado dos scanners 3D tradicionais. Uma alternativa é a utilização do Microsoft Kinect que, além de ser consideravelmente mais barato, é capaz de capturar os dados de profundidade com precisão necessária para discriminar sujeitos. O principal objetivo do presente trabalho é avaliar a performance do método 3DLBP para o reconhecimento de faces quando utilizando os mapas de profundidade gerados pelo Kinect. Outro objetivo é investigar quais regiões da face que desempenham melhor no reconhecimento de face.
