A system for environmental monitoring of hydroelectric reservoirs in Brazil

Environmental monitoring of aquatic systems is an important tool to support policy makers and environmental managers' decisions. Long-term, continuous collection of environmental data is fundamental to the understanding of an aquatic system. This paper aims to present the integrated system for environmental monitoring (SIMA), a long-term temporal series system with a web-based archive for limnological and meteorological data. The following environmental parameters are measured by SIMA: chlorophyll-a (µgL-1), water surface temperature (ºC), water column temperature by a thermistor string (ºC), turbidity (NTU), pH, dissolved oxygen concentration (mg L-1), electric conductivity (µS cm-1), wind speed (ms-1) and direction (º), relative humidity (%), shortwave radiation (Wm-2) and barometric pressure (hPa). The data were collected in a preprogrammed time interval (1 hour) and were transmitted by satellite in quasi-real time for any user within 2500 km of the acquisition point. So far, 11 hydroelectric reservoirs are being monitored with the SIMA buoy. Basic statistics (mean and standard deviation) and an example of the temporal series of some parameters were displayed at a database with web access. However, sensor and satellite problems occurred due to the high data acquisition frequency. Sensors problems occurred due to the environmental characteristics of each aquatic system. Water quality sensors rapidly degrade in acidic waters, rendering the collected data invalid. Data is also rendered invalid when sensors become infested with periphyton. Problems occur with the satellites' reception of system data when satellites pass over the buoy antenna. However, the data transfer at some inland locations was not completed due to the satellite constellation position. Nevertheless, the integrated system of water quality and meteorological parameters is an important tool in understanding the aquatic system dynamic. It can also be used to create hydrodynamics models of the aquatic system to allow for the study of meteorological implications to the water body.

Cyanobacteria detection in Guarapiranga Reservoir (São Paulo State, Brazil) using Landsat TM and ETM+ images

Algae bloom is one of the major consequences of the eutrophication of aquatic systems, including algae capable of producing toxic substances. Among these are several species of cyanobacteria, also known as blue-green algae, that have the capacity to adapt themselves to changes in the water column. Thus, the horizontal distribution of cyanobacteria harmful algae blooms (CHABs) is essential, not only to the environment, but also for public health. The use of remote sensing techniques for mapping CHABs has been explored by means of bio-optical modeling of phycocyanin (PC), a unique inland waters cyanobacteria pigment. However, due to the small number of sensors with a spectral band of the PC absorption feature, it is difficult to develop semi-analytical models. This study evaluated the use of an empirical model to identify CHABs using TM and ETM+ sensors aboard Landsat 5 and 7 satellites. Five images were acquired for applying the model. Besides the images, data was also collected in the Guarapiranga Reservoir, in São Paulo Metropolitan Region, regarding the cyanobacteria cell count (cells/mL), which was used as an indicator of CHABs biomass. When model values were analyzed excluding calibration factors for temperate lakes, they showed a medium correlation (R²=0.81, p=0.036), while when the factors were included the model showed a high correlation (R²=0.96, p=0.003) to the cyanobacteria cell count. The empirical model analyzed proved useful as an important tool for policy makers, since it provided information regarding the horizontal distribution of CHABs which could not be acquired from traditional monitoring techniques.

Injuries by marine and freshwater stingrays: history, clinical aspects of the envenomations and current status of a neglected problem in Brazil

Stingrays are a group of rays - cartilaginous fish related to sharks - that have whiplike tails with barbed, usually venomous spines and are found around the world, especially the marine species. Despite recent reports of accidents involving these fish, they are not aggressive, reacting only when stepped on or improperly handled. Injuries by stingrays are seldom mentioned by historians, although they have always been present in riverine communities of inland waters and in South American coasts. Indeed, envenomations by stingrays are quite common in freshwater and marine fishing communities. Although having high morbidity, such injuries are neglected because they have low lethality and usually occur in remote areas, which favor the use of folk remedies. In the present review article, historical aspects of injuries caused by stingrays in Brazil and their distribution on the coast of Sao Paulo state and riverine communities of the North, Midwest and Southeast regions were studied. In addition, other aspects were analyzed such as clinical features, therapeutic methods, preventive measures and trends in occurrence of these accidents in the country, particularly in areas in which freshwater stingrays had not been previously registered, being introduced after breaching of natural barriers.

Objetos lúdicos disponibilizados às crianças de 3 a 5 anos: o que encontramos na educação infantil?

The goal of this research is to identify and describe the recreational objects, or toys, children’s play and games offered by teachers from a public municipal school of early childhood education in Pederneiras, a city located inland São Paulo State. The research has started with a retrospective look of the childhood concept and of the recreational objects with in the classical era till the modernity, what has allowed to identify how to play was in history and what is its relation with education. In order to understand how the recreational objects have been seen at school we have made a survey of the oficial Brazilian documents related to the childhood education. The benchmark survey has allowed the organization of a half structured questionnaire and the Kobayashi studies (2009, 2011), was the mean used to identify and classify the recreational objects found at school. The data collected in the benchmark survey in the field remark and by the questionnaire have permitted to identify here recreational objects available by teachers in early childhood education of 3 to 5 years old children at the school mentioned and what they think about the theme, on the other hand the studies performed have allowed us to analyse the adaptation and validity of the recreational objects already found

Alfabetização no ensino fundamental de nove anos: avaliação discente e suas implicações para as práticas pedagógicas

This paper focuses data from discussions done with teachers who work with the three early years of nine-years elementary chool, in two Municipal schools of São Paulo inland, in order to investigate the students’ literacy degree. Considering a test applied to students of three early years of those schools, this study deals with the literacy performance results of 153 children of third school year. It also relates data of this test with some aspects that have characterized the literacy teachers’ practices. Initially, it presents considerations about the literacy process in extent of nine-years elementary school and some implications for the teachers’ practices. Then, it emphasizes the test results of third year students, pointing out what skills were already developed by them in literacy process and what skills must be improved. Results show that those children are not literated. They demonstrate difficulties in the appropriation of reading and writing skills, even in the third school year. It suggests the teachers’ need to reorganize their practices in classroom and to revise students’ literacy process, allowing to every student the full appropriation of reading and writing.

As concepções urbanísticas que impulsionaram o desenvolvimento do capitalismo e a reprodução da força de trabalho em São Paulo: sanear e excluir

This article aims to rank the main concepts in vogue in the city of São Paulo who contributed to the formulation of a shared urban oriented capitalist development and reproduction of the workforce. This way, it will discuss the main issues raised in the period, which is between the first decades of the XX Century to the end of the 1950s, trying to foresee how they worked as engineers and architects to incorporate the urbanistic proposals from Europe and the United States. And then, we will present, on the first four sections of this article, points of view that effectively impacted the paulista urban thought of the first half of the XX century: Sanitarism, pendular conception between the Mesologic Theory and the Microbian Theory; the Historicist formulation of Camillo Sitte; Howard´s garden-town and The French Experience. Our analyses were formulated having as a reference the broad systematization of bibliography and documents performed at the Arquivo Histórico Municipal (Intermediário) de Araraquara (Historical Municipal Archive from Araraquara), consultations at the the books of the library of the biblioteca da Faculdade de Arquitetura e Urbanismo da USP (USP Architecture and Urbanism College) and at the Faculdade de Ciências e Letras da UNESP, Araraquara-SP( College of Sciences and Languages from UNESP, campus Araraquara). The analisys of the performed research show that one urbanistic torrent at São Paulo State with clear influences from the conceptions that led the urbanistic debates in the first half of the XX Century. Although these conceptions compose a painting of urban transformations at São Paulo city and noticeably in some inland cities, previously to the solidification of a whole proposition for the city that was later called of Directive Plan.

Validity and behaviour of tropospheric gradients estimated by GPS in Corsica

Estimation of tropospheric gradients in GNSS data processing is a well-known technique to improve positioning (e.g. Bar-Sever et al., 1998; Chen and Herring, 1997). More recently, several authors also focused on the estimation of such parameters for meteorological studies and demonstrated their potential benefits (e.g. Champollion et al., 2004). Today, they are routinely estimated by several global and regional GNSS analysis centres but they are still not yet used for operational meteorology.This paper discusses the physical meaning of tropospheric gradients estimated from GPS observations recorded in 2011 by 13 permanent stations located in Corsica Island (a French Island in the western part of Italy). Corsica Island is a particularly interesting location for such study as it presents a significant environmental contrast between the continent and the sea, as well as a steep topography.Therefore, we estimated Zenith Total Delay (ZTD) and tropospheric gradients using two software: GAMIT/GLOBK (GAMIT version 10.5) and GIPSY-OASIS II version 6.1. Our results are then compared to radiosonde observations and to the IGS final troposphere products. For all stations we found a good agreement between the ZWD estimated by the two software (the mean of the ZWD differences is 1 mm with a standard deviation of 6 mm) but the tropospheric gradients are in less good agreement (the mean of the gradient differences is 0.1 mm with a standard deviation of 0.7 mm), despite the differences in the processing strategy (double-differences for GAMIT/GLOBK versus zero-difference for GIPSY-OASIS).We also observe that gradient amplitudes are correlated with the seasonal behaviour of the humidity. Like ZWD estimates, they are larger in summer than in winter. Their directions are stable over the time but not correlated with the IWV anomaly observed by ERA-Interim. Tropospheric gradients observed at many sites always point to inland throughout the year. These preferred directions are almost opposite to the largest slope of the local topography as derived from the world Digital Elevation Model ASTER GDEM v2. These first results give a physical meaning to gradients but the origin of such directions need further investigations.
