The use of biomass as an energy source has been increasing in Brazil, with emphasis on the use of wood biomass, such as bark, wood chips and sawdust, that after receiving the appropriate treatment can be used in burners for power generation. However, from this burning are emitted fine particles known as particulate matter and a wide range of toxic organic and inorganic components in the form of gases that contribute greatly to air pollution and global warming, affecting human health, the environment and climate. The objective of this project was the quantification of gaseous and particulate, using and evaluating the equipment DR4000 ( Dataram 4 ) sampling of particulates smaller than 2.5μm and EUROTRON ( Ecoline 4000 ) when sampling gaseous pollutants, emitted from the burning of biomass in real time in the firing burner to a chimney attached biomass . We note that there are no specific rules that establish emission limits for particulate matter with diameter less than 2.5μm that are most harmful to human health and the highest concentrations reached about 800000μg/m3, for smaller diameters. It is noticeable the need for sampling of pollutants especially in industries that use biomass to fuel that could be implanted emission control equipment

The Biosusceptometry AC (BAC) is a research tool that has been extensively explored by the group Biomagnetism IBB-UNESP for monitoring of the gastrointestinal tract, its response to a known drug or in vivo performance of solid dosage forms. During this period the BAC, which has the characteristics of high sensitivity and low cost, has been developed primarily for recording signals contraction of activity and traffic human gastrointestinal tract. With the possibility of producing images with this instrumentation, it was possible to evaluate different situations in vitro and in vivo for physiological studies and pharmaceuticals. Considering the good performance of this system to produce planar images, the first aim of the BAC system tomography (TBAC) was to evaluate the system performance of BAC to produce tomographic images of phantoms ferromagnetic for a single channel system. All these applications were only possible because of their sensitivity to materials of high magnetic suscepitibility as ferrite, which allow to produce an electrical signal proportional to the variation of the magnetic flux generated by the presence of magnetic marker next to a first-order gradiometer. Measuring this variation at various points was possible to generate planar images that recently came to be produced in systems with multiple detectors, said multi-channels. From planar images, also producing tomographic images of simulators BAC bars in a system of 13 channels using only the center channel, with good results when applied to simple objects as one and two bars. When testing the resolution of the system with more elaborate forms the quality and resolution of images reconstructed is not satisfactory, which would be solved by increasing the spatial sampling rate and hence the acquisition time. The present system works with an acquisition time of about five hours. Whereas this system will be applied for in vivo experiments, the acquisition time became a ...

It is clear today the ever-accelerating search for new fuels that will eventually replace those that will survive in our society, which are fossil fuels. For this reason, a fuel used since the dawn of humanity and much studied since then, considered the generator of clean, renewable energy, can earn more and more space in the power generation sector, which is biomass. We performed two experiments with two different types of biomass, one from the Amazon rainforest and other pine and eucalyptus as waste from the sawmill UNESP Itapeva. In the first experiment, conducted at the Laboratory of Combustion and Propulsion INPE Cachoeira Paulista were conducted three tests in a chimney with a fan creating forced ventilation, where the biomass was burned and deposited on a support beneath the hood. In the second experiment was conducted to analyze the emission of particulate matter using biomass (waste) from the sawmill on the campus of UNESP experimental Itapeva the burning of it in a burner for heating water for a wood oven. In these experiments we used a particle called DATARAM4 sampler that is capable of sampling both outdoors and inside of pipelines, which is the focus of this work. With this equipment it was possible to measure the concentration of particulate matter in all the firings as above, and compare them to levels acceptable in the current law, always trying to analyze the so-called fine particles, which are those with diameters less than 2.5 μm. Using data obtained from the equipment was also possible to evaluate the diametral distribution of particulate matter in question, and verify which phases of the flares in the concentration and the diameters of the particles are the most critical. In this work we concluded that in all firings conducted concentrations of particulate matter were higher than that allowed by the law, and the diameters were found that are more harmful to human health

The human development requires that urban and industrial centers to be interconnected, with different modes of transport, among which the land transport is the most important. The roads may cross sections of remnant forests, which contain considerable diversity of species. Besides habitat fragmentation, the roads can also hinder connectivity between different patches. This kind of impact is not very well known. We reviewed the literature on Road Ecology in the Neotropics, and its relation to conservation of the biodiversity. We considered 32 papers on this issue. We compiled what is known and what the direction to take, as well as failures to be avoid in the samples, for future studies involving Road Ecology. Despite the growing trend of this subject, flaws in the methods for this type of studies show that there is no standardization of sampling effort or of experimental design for these studies. We also found that there is a lack of study of some taxonomic classes. The simple animal roadkills records do not make clear the impacts of the roads. The necessity of different designs for specific taxonomic classes must be considered, in order to produce better quality data and reliable results. Animals can avoid roads, getting isolated and limited to smaller areas of life. The dispersal and colonization of exotic flora species are facilitated by roads. Nevertheless, it is not known how or at which scale, these invasions impact the local communities. Finally, we proposed a flowchart as a conceptual model illustrating the potential impacts of roads on biodiversity and ecology interactions

The main purpose of this investigation is to analyze the most frequent simple terms, fixed and semifixed expressions in the subarea of Social Political Economy in Portuguese and their corresponding terms in English, found in fifteen papers written by Bresser-Pereira and in his self-translated texts. The methodology used is the Corpus-Based Translation (Baker, 1992, 1993, 1995, 1996; Camargo, 2005, 2007), Corpus Linguistics (Berber Sardinha, 2004) and Terminology (Barros, 2004). Results show that terms and expressions used in the source texts have no univocity within the specialized language related to the Brazilian Social Sciences. The terms translated into English also reflect variation due to the options chosen by the selftranslator as he seeks to adapt the theoretical concepts to the possibilities of the Target Language.

The main purpose of this article is to investigate the most frequent simple terms as well as fixed and semi-fixed expressions in Social Anthropology of Civilization subarea in Portuguese and their corresponding terms in English, found in two works written by the anthropologist Darcy Ribeiro. The methodology used is that of Corpus-Based Translation Studies (BAKER, 1995, 1996, 1997; CAMARGO, 2005, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and Terminology (BARROS, 2004; KRIEGER &FINATTO, 2004). Results show that there are similarities and differences among the use of the terms in the main subcorpora composed of source and target texts and in the comparable corpora in Portuguese and in English. This data indicate that terms and expressions are not univocal in the anthropological language due to the differences in the conceptualization of the same referents by different specialists in the area.

Brazil was one of the countries that stood out in the list of nations that publishes more articles in scientific journals. From 2007 to 2008, the Brazilian scientific production has moved from 15th to 13rd place in the world ranking published articles in professional journals. However, 60% of articles published by the Brazilians are in Portuguese, which makes the Brazilian work have little international attention. The purpose of this research is to build and analyze a parallel corpus composed of a book of Remote Sensing and its translation in the direction English into Portuguese in order to create a glossary of most recurrent terms in the literature of Remote Sensing. The achievement of these goals will take for theoretical and methodological foundation the Corpus-Based Translation Studies (BAKER, 1993, 1995, 1996; CAMARGO, 2005), Corpus Linguistics (BERBER SARDINHA, 2004) and principles of Terminology (BARROS, 2004; KRIEGER & FINATTO, 2004). It will also use Wordsmith Tools program and its tools. Besides the parallel corpus, we will also build two comparable corpora respectively from articles published in Brazilian and international journals in the area. The first results show that the translators made use of greater variation of vocabulary in their translations, which can be a way to make the text more clear to the reader. For the analysis of glossary entries, professionals from the National Institute for Space Research - INPE, will be consulted and their views aggregated to this research to give consistency to the production of the proposed bilingual glossary.
