Análise da percepção da variação do campo térmico na cidade de São Paulo-SP: o exemplo da subprefeitura Sé

This research aimed to analyze the spatial area for the design of the Heat Island of Subprefecture Sé, in São Paulo-SP, with the support of geotecnology and based on the study of environmental perception. We used remote sensing products such as maps ofland use and soil temperature and apparent surface to evaluate the thermal conditions considered critical points in the central area of the municipality. The methodology used was qualitative analysis, based on interviews with the people, allowing rescue geoecology the conditioning aspects of the city, with an emphasis on environmental perception. This study aimed toanalyze the perception of the variation of the thermal field in São Paulo. The results indicated that (95%) of respondents feel that the temperature of the central area has increased each year, and the district that stood out was the Sé, due to intense use and occupation of land and contribute one of the largest shopping centers. Districts with points given for having better thermal comfort were Santa Cecília, the República and Bela Vista, due to their larger amount of green areas by fiscal court, which act as local refrigerators. It was found that the respondents have the perception and awareness of their spa directly related to the quality of life. Through analysis of several variables involved, proposals and strategies may support public policies and urban planning

Análise das ocorrências de escorregamento por meio de imagens Geoeye em trecho da faixa de dutos Rio de Janeiro - Belo Horizonte

The analysis of natural processes, such as landslides, has a great importance for the prevention of accidents in pipelines, since it might compromise its security, with serious social and environmental implications. Considering the large territorial dimensions that pipelines can reach, remote sensing tools have great applicability for data acquisition, allowing the analysis of large areas in regular time periods. This study aims to analyze the relations between the occurrence of landslides and its natural conditionings, on a stretch of the ORBEL pipeline, in the municipalities of Duque de Caxias, Nova Iguaçu and Belford Roxo – Rio de Janeiro. GeoEye sensor system images were used with spatial resolution of 0.5 m, from November/2009, January/2010 and March/2010, that are months of summer rains. The work involved the characterization of the study area and existing landslides, through bibliographic data collection; the application of visual analysis techniques for the extraction of landslide scars and fractures; preparation of maps for the landslide constraints and preparation of the susceptibility map. In the images from November only three landslide scars were extracted, while in January there were 166 and 111 in March. Difficulties were found with the shading in the images. From the relations among landslide scars, lithological units, relief systems, slope, downhill profile and the generated map of landslide susceptibility, presented in 1:70,000 scale, it was possible to conclude that slope is the main determinant of the process, allied secondarily to downhill profile, relief systems and lithology

Distribuição espacial dos ninhos de Athene cunicularia (coruja-buraqueira) e dinâmica de sua utilização

A coruja-buraqueira (Athene cunicularia) nidififica no chão e, com frequência, ocorre em ambientes bastante urbanizados como no campus universitário da UNESP em Botucatu, SP região centro-oeste paulista. Os objetivos do estudo foram descrever as características físicas das escavações, distribuição espacial, formas de utilização e avaliar que elementos presentes nas áreas urbanas são importantes para a seleção dos sítios de nidificação. Foram monitorados 6 grupos familiares desde 2011, cuja população e o número de ninhos foram contabilizados e a localização, georeferenciados. Os dados comportamentais foram registrados em caderno de campo, fotografados e filmados. A densidade populacional no câmpus foi de 0,03 indivíduos por Km² com os sítios de nidificação vizinhos tendo a distância mínima de 140,0 metros e máxima de 378 metros. As tocas apresentaram 50,6± 5,6cm de diâmetro, a maioria construída em terreno com declive. As corujas selecionaram sítios de nidificação em áreas abertas e gramadas contendo no entorno poleiros naturais (árvores, arvoretas, arbustos) e artificiais (placas, postes, peitoral de janelas, etc) e próximos a bueiros e postes com iluminação artificial. Estes dois últimos constituíram atrativos paras as suas presas (artrópodes e roedores) e a análise de ergagrópilas revelou a ocorrência de 5 grupos taxonômicos de artrópodes: 65,4% de Coleóptera, 27,2% de Orthoptera, 4,6% de Blatodea, 1,4% de Aranae, 0,9% de Hymenoptra e 0,4% de Mantodea. Os resultados obtidos mostraram que as corujas-buraqueiras levaram em consideração características como oferta abundante de alimento, principalmente, de artrópodes que se concentravam nas área iluminadas e nos bueiros. A estabilidade temporal dos sítios de nidificação nestes três anos de monitoramento acompanhada de sucesso reprodutivo de 50% revela que a despeito do intenso tráfego de veículos e transeuntes no campus, o ambiente ...

Imagens de satélite na análise da relação entre queimadas, aerossóis atmosféricos e precipitação

The direct and indirect effects of atmospheric aerossols in the amazonic climate have been focus of many published. This work aims to analyze a possible relation among Burns, atmospheric aerossols and precipitation above South America. It uses the avaluable data from the satellites AQUA/TERRA and TRMM and the images furnished by NOAA and GOES. These analysis can provide some explanations about the effects of emission of aerosols by burns on the composition of atmosphere and cloud formation, mainly in Amazon. We use the Aerosol Optical Depth (AOD) from MODIS/TERRA-AQUA, burns index from CPTEC and rain rate from TRMM. The data we use were obtained from 2000 until 2012. The study is divided in two parts. In the first one, it was performed a quantitative analysis between number of burns and aerosols emission. It was identified a great variability in space and time of the AOD on South America. On the north, northeast and center-west, the AOD is significant during the winter period, with peak on August and September. The southeast is affected by aerosols from center-west due to the dynamical transport. In the second part, it was evaluated the relation between AOD and precipitation in a 13-year period. The statistical analysis shows up a negative correlation of 0.72 between August and October, on Legal Amazon. These result indicate an inverse relation between AOD and rain rate. The other months present not significant correlation. These results are in a good agreement with the literature, in which in-situ methods were applied or combined with satellites data. The increasing of aerosols concentration in the atmosphere are reinforced during drier years. It can affect the increasing process of water drops, decreasing the precipitation. We also verified higher values of AOD (0.25 - 0.3) during years with El Niño, than the climatologically average (~0.15 - 0.2), ... (Complete abstract click electronic access below)

Distribuição espacial das assembleias de peixes em dois trechos do alto rio Paranapanema e lagoas marginais associadas: composição e estrutura

Ichthyofaunistic studies aims to broad the knowledge of composition, abundance and distribution of species in certain areas, and when possible, to infer patterns of distribution, as well as extrinsic factors that affect these patterns in space and time. The Paranapanema River suffers the impact of the construction of hydroelectric power plants in cascade system along its main channel, changing the characteristics of lotic to lentic and semi-lentic. These changes affect the entire biocenosis and the surroundings of the reservoir and, in particular, the fish fauna. In this context, the aim of this study was to characterize the fish assemblage in two lakes and stretches of the main channel, located near the outfall of the Paranapanema River, Jurumirim reservoir area, comparing them to their composition and structure, using ecological indices as tools. Fish were caught every three months from April 2011 to January 2013, using gill nets of various mesh openings in four stretches: Environment 1 - Calha Sete Ilhas, Environment 2 - Calha Poço da Pedra, Environment 3 - Lagoa Sete Ilhas and Environment 4 - Lagoa Poço de Pedra. After the capture, the specimens were identified and biometric analysis was performed (total and standard length weight). We captured 4,006 individuals belonging to four orders and 34 species, 31 native species and three non-native species. In abundance (n) and number of species (S), there was a predominance of Characiformes (57 %) followed by Siluriformes (31%). Overall, most of the species was constant concerning the frequency of capture. The five most representative species in abundance were Schizodon intermedius, Cyphocarax modestus, Pimelodus maculatus, Hoplosternum littorale and Serrasalmus maculatus, contributing with 60% of total individuals captured. Regarding the stretches, these species present diversity (H'), evenness (E), dominance (D) and richness (d) of similar species, since the abundance was higher in ...

Mapeamento do nível radiométrico e construção de mapa espacial em serviço de medicina nuclear

Nuclear Medicine is a medical modality of therapy and diagnostic imaging using unsealed radioactive sources for its purposes. This routine activity promotes the transit of radioactive sources for the area of installation, beyond the transit of patients injected with radioisotope, which also contribute to raising the radiometric level of environment. As a consequence, it has exposured workers and public individuals to the ionizing radiation. There are protective mechanisms of radiation exposure, personal protective equipments, and measurement planes established in standard measurement at certain points of the environment in order to identify any increase in radiometric levels and \ or contamination, but do not cover the entire space occupied by workers and patients. To accomplish with the individual dose limits established by the National Commission of Nuclear Energy, it is interesting if there is an individualized classification for each Nuclear Medicine service. This work aimed to promote an analysis of the radiometric level distribution across the extent of the Technical Nuclear Medicine Sector of Hospital of the Botucatu Medical School, and produce a spatial map to identify locations with higher exposure rate to the ionizing radiation, can be used as a risk map to assist the Occupationally Exposed Individuals (IOE). To perform the radiometric levels checking it was used a digital Geiger-Muller detector available in the sector, due to its practicality compared to other detectors. Measurements were carried out at four different times for all days of the week, at points strategically established to cover all the installation
