    The Rio Tinto, located in southwest Spain, exhibits a nearly constant, acidic pH-value along its course. Due to the formation of sulfate minerals, Rio Tinto is considered a potential analogue site for sulfate-rich regions on Mars, in particular at the landing site of the Mars Exploration Rover Opportunity, where the ferric sulfate mineral jarosite was identified with Opportunity's Moessbauer spectrometer. Primary and secondary mineralogy was investigated in situ with portable Raman and Moessbauer spectrometers at four different Rio Tinto sampling sites. The two techniques analyse different sample portions due to their specific field of view and sampling depth and provide complementary mineralogical information.

    The recent discovery of abundant sulfate minerals, particularly Jarosite by the Opportunity Rover at Sinus Merdiani on Mars has been interpreted as evidence for an acidic lake or sea on ancient Mars [1,2], since the mineral Jarosite is soluble in liquid water at pH above 4. The most likely mechanism to produce sufficient protons to acidify a large body of liquid water is near surface oxidation of pyrite rich deposits [3]. The acidic waters of the Rio Tinto, and the associated deposits of Hematite, Goethite, and Jarosite have been recognized as an important chemical analog to the Sinus Merdiani site on Mars [4]. The Rio Tinto is a river in southern Spain that flows 100 km from its source in the Iberian pyrite belt, one of the Earth s largest Volcanically Hosted Massive Sulfide (VHMS) provinces, into the Atlantic ocean. The river originates in artesian springs emanating from ground water that is acidified by the interaction with subsurface pyrite ore deposits. The Mars Analog Rio Tinto Experiment (MARTE) has been investigating the hypothesis that a subsurface biosphere exists at Rio Tinto living within the VHMS deposit living on chemical energy derived from sulfur and iron minerals. Reduced iron and sulfur might provide electron donors for microbial metabolism while in situ oxidized iron or oxidants entrained in recharge water might provide electron acceptors.

    A field campaign was organized in September 2006 by Centro de Astobiologica (Spain) and Washington University (St Louis, USA) for the geological study of the Rio Tinto river bed sediments using a suite of in-situ instruments comprising an ASD reflectance spectrometer, an emission spectrometer, panoramic and close-up color imaging cameras, a life detection system and NASA's CheMin 4 XRD/XRF prototype. The primary objectives of the field campaign were to study the geology of the site and test the potential of the instrument suite in an astrobiological investigation context for future Mars surface robotic missions. The results of the overall campaign will be presented elsewhere. This paper focuses on the results of the XRD/XRF instrument deployment. The specific objectives of the CheMin 4 prototype in Rio Tinto were to 1) characterize the mineralogy of efflorescent salts in their native environments; 2) analyze the mineralogy of salts and oxides from the modern environment to terraces formed earlier as part of the Rio Tinto evaporative system; and 3) map the transition from hematite-dominated terraces to the mixed goethite/salt-bearing terraces where biosignatures are best preserved.

    2005-12-01

    Biological systems on Earth require three key ingredients-- liquid water, an energy source, and a carbon source, that are found in very few extraterrestrial environments. Previous examples of independent subsurface ecosystems have been found only in basalt aquifers. Such lithotrophic microbial ecosystems (LME) have been proposed as models for steps in the early evolution of Earth's biosphere and for potential biospheres on other planets where the surface is uninhabitable, such as Mars and Europa.. The Mars Analog Rio Tinto Experiment (MARTE) has searched in a volcanic massive sulfide deposit in Rio Tinto Spain for a subsurface biosphere capable of living without sunlight or oxygen and found a subsurface ecosystem driven by the weathering of the massive sulfide deposit (VMS) in which the rock matrix provides sufficient resources to support microbial metabolism, including the vigorous production of H2 by water-rock interactions. Microbial production of methane and sulfate occurred in the sulfide orebody and microbial production of methane and hydrogen sulfide continued in an anoxic plume downgradient from the sulfide ore. Organic carbon concentrations in the parent rock were too low to support microbes. The Rio Tinto system thus represents a new type of subsurface ecosystem with strong relevance for exobiological studies. Commercial drilling was used to reach the aquifer system at 100 m depth and conventional laboratory techniques were used to identify and characterize the biosphere. Then, the life search strategy that led to successful identification of this biosphere was applied to the development of a robotic drilling, core handling, inspection, subsampling, and life detection system built on a prototype planetary lander that was deployed in Rio Tinto Spain in September 2005 to test the capability of a robotic drilling system to search for subsurface life. A remote science team directed the simulation and analyzed the data from the MARTE robotic drill. The results

    Between 15 and 25 April 2011 in the framework of the PolAres programme of the Austrian Space Forum, a five-day field test of the Aouda.X spacesuit simulator was conducted at the Rio Tinto Mars-analogue site in southern Spain. The field crew was supported by a full-scale Mission Control Center (MCC) in Innsbruck, Austria. The field telemetry data were relayed to the MCC, enabling a Remote Science Support (RSS) team to study field data in near-real-time and adjust the flight planning in a flexible manner. We report on the experiences in the field of robotics, geophysics (Ground Penetrating Radar) and geology as well as life sciences in a simulated spaceflight operational environment. Extravehicular Activity (EVA) maps had been prepared using Google Earth and aerial images. The Rio Tinto mining area offers an excellent location for Mars analogue simulations. It is recognised as a terrestrial Mars analogue site because of the presence of jarosite and related sulphates, which have been identified by the NASA Mars Exploration Rover "Opportunity" in the El Capitan region of Meridiani Planum on Mars. The acidic, high ferric-sulphate content water of Rio Tinto is also considered as a possible analogue in astrobiology regarding the analysis of ferric sulphate related biochemical pathways and produced biomarkers. During our Mars simulation, 18 different types of soil and rock samples were collected by the spacesuit tester. The Raman results confirm the presence of minerals expected, such as jarosite, different Fe oxides and oxi-hydroxides, pyrite and complex Mg and Ca sulphates. Eight science experiments were conducted in the field. In this contribution first we list the important findings during the management and realisation of tests, and also a first summary of the scientific results. Based on these experiences suggestions for future analogue work are also summarised. We finish with recommendations for future field missions, including the preparation of the experiments

  13. A Search for Life in the Subsurface At Rio Tinto Spain, An Analog To Searching For Life On Mars.

    Most familiar life forms on Earth live in the surface biosphere where liquid water, sunlight, and the essential chemical elements for life are abundant. However, such environments are not found on Mars or anywhere else in the solar system. On Mars, the surface environmental conditions of pressure and temperature prevent formation of liquid water. Furthermore, conditions at the Martian surface are unfavorable to life due to intense ultraviolet radiation and strong oxidizing compounds that destroy organic compounds. However, subsurface liquid water on Mars has been predicted on theoretical grounds. The recent discovery of near surface ground ice by the Mars Odyssey mission, and the abundant evidence for recent Gully features observed by the Mars Global Surveyor mission strengthen the case for subsurface liquid water on Mars. Thus, the strategy for searching for life on Mars points to drilling to the depth of liquid water, bringing samples to the surface and analyzing them with instrumentation to detect in situ organisms and biomarker compounds. The MARTE (Mars Astrobiology Research and Technology Experiment) project is a field experiment focused on searching for a hypothesized subsurface anaerobic chemoautotrophic biosphere in the region of the Rio Tinto, a river in southwestern Spain while also demonstrating technology relevant to searching for a subsurface biosphere on Mars. The Tinto river is located in the Iberian Pyrite belt, one of the largest deposits of sulfide minerals in the world. The surface (river) system is an acidic extreme environment produced and maintained by microbes that metabolize sulfide minerals and produce sulfuric acid as a byproduct. Evidence suggests that the river is a surface manifestation of an underground biochemical reactor. Organisms found in the river are capable of chemoautotrophic metabolism using sulfide and ferric iron mineral substrates, suggesting these organisms could thrive in groundwater which is the source of the Rio Tinto

    The Tinto and Odiel rivers drain 100 km from the Rio Tinto sulphide mining district, and join at a 20-km long estuary entering the Atlantic Ocean. A reconnaissance study of heavy metal anomalies in channel sand and overbank mud of the river and estuary by semi-quantitative emission dc-arc spectrographic analysis shows the following upstream to downstream ranges in ppm (??g g-1): As 3,000 to TOC), sandysilty overbank clay has been analyzed to represent suspended load materials. The high content of heavy metals in the overbank clay throughout the river and estuary systems indicates the importance of suspended sediment transport for dispersing heavy metals from natural erosion and anthropogenic mining activities of the sulfide deposit. The organic-poor (0.21-0.37% TOC) river bed sand has been analyzed to represent bedload transport of naturally-occurring sulfide minerals. The sand has high concentrations of metals upstream but these decrease an order of magnitude in the lower estuary. Although heavy metal contamination of estuary mouth beach sand has been diluted to background levels estuary mud exhibits increased contamination apparently related to finer grain size, higher organic carbon content, precipitation of river-borne dissolved solids, and input of anthropogenic heavy metals from industrial sources. The contaminated estuary mud disperses to the inner shelf mud belt and offshore suspended sediment, which exhibit metal anomalies from natural erosion and mining of upstream Rio Tinto sulphide lode sources (Pb, Cu, Zn) and industrial activities within the estuary (Fe, Cr, Ti). Because heavy metal contamination of Tinto-Odiel river sediment reaches or exceeds the highest levels encountered in other river sediments of Spain and Europe, a detailed analysis of metals in water and suspended sediment throughout the system, and epidemiological analysis of heavy metal effects in humans is appropriate. ?? 1993 Estuarine Research Federation.

  18. Gender relations, the gendered division of labour and health: the case of the women factory workers of Rio Tinto, northeast Brazil, 1924-91.

    Ferreira De Macedo, M B

    1996-01-01

    This article examines gendered work-health relationships among female factory workers in Rio Tinto, a textile factory town in Brazil. The author draws on her own and her parents' experiences as factory workers and as residents of Rio Tinto. In addition, she gathered research during 1982-86 and 1988-93, interviewing 30 female and 12 male workers. Findings from 1924-58 and 1959-91 indicate that the family structure and work process were interlinked. Self-images are construed to be the intersection of social relations of sex and class, psychopathology, and the concept of work positions. Gendered relations are a social construction, and awareness of these relations is based on a hierarchy and form of power based on a gendered division of labor. Gendered relations arise out of a specific historical context. Social practices reflect the relationship between sexual division of labor and gendered social relations, their modalities, shape, and periodization. The work-health relationship is expressed in the gendered technical organization of work, the gendered socialization of work, and domestic labor. The period of 1917-58 reflects the capitalist influences. When women became wage earners, their management of household tasks was changed. Men took over the heavy tasks, and women performed tasks that required skill and patience. Work-related health impacts, such as deformed knees or severed fingers, and accidents varied with the task. Women adapted to work conditions. During the 1940s, female workers refused to join the collective protests of men for better wages and conditions. The dream of progress faded by 1964. After 1959, new gendered relations of production and reproduction emerged. Labor laws were passed; new machines were introduced. During 1965-70, the health issues were headaches, irritability, and anxiety. 1970-91 brought a hollowness of spirit and the search for an explanation for the violence they had experienced.

  20. Fungal Iron Biomineralization in Río Tinto

    2016-04-01

    Full Text Available Although there are many studies on biomineralization processes, most of them focus on the role of prokaryotes. As fungi play an important role in different geological and biogeochemical processes, it was considered of interest to evaluate their role in a natural extreme acidic environment, Río Tinto, which has a high level of fungal diversity and a high concentration of metals. In this work we report, for the first time, the generation of iron oxyhydroxide minerals by the fungal community in a specific location of the Tinto basin. Using Transmission Electron Microscopy (TEM and High Angle Angular Dark Field coupled with Scanning Transmission Electron Microscopy (HAADF-STEM and Energy-Dispersive X-ray Spectroscopy (EDX, we observed fungal structures involved in the formation of iron oxyhydroxide minerals in mineralized sediment samples from the Río Tinto basin. Although Río Tinto waters are supersaturated in these minerals, they do not precipitate due to their slow precipitation kinetics. The presence of fungi, which simply provide charged surfaces for metal binding, favors the precipitation of Fe oxyhydroxides by overcoming these kinetic barriers. These results prove that the fungal community of Río Tinto participates very actively in the geochemical processes that take place there.

    Full Text Available Os benefícios do consumo diário de vinho tinto já são bem conhecidos e descritos, e incluem a diminuição da probabilidade de ocorrência de doenças coronárias e de complicações cardiovasculares. Atribui-se esta ação benéfica e “protetora” à presença de compostos flavonoides encontrados na casca da uva (Vitis vinifera, principalmente antocianidinas e do derivado fenólico resveratrol. Apesar disto, o vinho é caracterizado por apresentar entre 5 a 12% de álcool e o seu consumo diário pode trazer, juntamente aos benefícios cardíacos grandes prejuízos à saúde. O presente trabalho objetivou verificar se o consumo frequente de suco de uva tinto seria capaz de trazer os mesmos efeitos protetores do vinho tinto.  Observou-se nestas análises que a atividade antioxidante dos vinhos amostrados foi superior a dos sucos. Não foi possível observar diferença significativa entre os teores de compostos fenólicos totais nas amostras de suco e de vinho. Uma vez que a atividade antioxidante está muito relacionada à proteção cardiovascular, conclui-se que o consumo do suco de uva tinto não é capaz de substituir o vinho em sua ação protetora

    2014-09-01

    Full Text Available The geomicrobiological characterization of the water column and sediments of Río Tinto (Huelva, Southwestern Spain have proven the importance of the iron and the sulfur cycles, not only in generating the extreme conditions of the habitat (low pH, high concentration of toxic heavy metals, but also in maintaining the high level of microbial diversity detected in the basin. It has been proven that the extreme acidic conditions of Río Tinto basin are not the product of 5000 years of mining activity in the area, but the consequence of an active underground bioreactor that obtains its energy from the massive sulfidic minerals existing in the Iberian Pyrite Belt. Two drilling projects, MARTE (Mars Astrobiology Research and Technology Experiment (2003–2006 and IPBSL (Iberian Pyrite Belt Subsurface Life Detection (2011–2015, were developed and carried out to provide evidence of subsurface microbial activity and the potential resources that support these activities. The reduced substrates and the oxidants that drive the system appear to come from the rock matrix. These resources need only groundwater to launch diverse microbial metabolisms. The similarities between the vast sulfate and iron oxide deposits on Mars and the main sulfide bioleaching products found in the Tinto basin have given Río Tinto the status of a geochemical and mineralogical Mars terrestrial analogue.

    The acidic waters of the Río Tinto rise from several acidic springs that emerge in the area surrounding Peña de Hierro (Fernández-Remolar et al., 2005). These springs are located above minor normal faults that act as natural conduits for the water from the underlying deep aquifer. Although it has been suggested that the acidity of the river originates from the biooxidation of massive and stockwork sulfides (Fernández-Remolar et al., 2008a), the location of the source for these acidic solutions has not previously been established. This lack of evidence has been used to suggest that the acidity of the Río Tinto may be the product of the most conspicuous of the possible source, the extensive mining of the area over approximately the last 5000 years (Davis et al., 2000). In this paper, we report resistivity and time-domain electromagnetic sounding data from the Río Tinto aquifer to a depth of ∼600 m, revealing the locations for the acidic sources. Both types of data support the presence of two distinct geological units that we interpret as thrust sheets emplaced onto each other during the Variscan orogeny of the Carboniferous. These units, both of which contain massive and stockwork sulfides, act as the aquifer for the acidic waters of the Río Tinto. Under this scenario, which is in agreement with the geological record of the Río Tinto fluvial system for the past 6 Ma (Moreno et al., 2003), our results imply that mining activity had little influence on the generation of the acidic river waters.

    The Tinto and Odiel rivers are heavily affected by acid mine drainage from mining areas in the Iberian Pyrite Belt. In this work we have conducted a study along these rivers where surface water samples have been collected. Field measurements, total dissolved metals and Fe and inorganic As speciation analysis were performed. The average total concentration of As in the Tinto river (1975 {mu}g L{sup -1}) is larger than in the Odiel river (441 {mu}g L{sup -1}); however, the mean concentration of As(III) is almost four times higher in the Odiel. In wet seasons the mean pH levels of both rivers (2.4 and 3.2 for the Tinto and Odiel, respectively) increase slightly and the amount of dissolved total arsenic tend to decrease, while the As(III)/(V) ratio strongly increase. Besides, the concentration of the reduced As species increase along the water course. As a result, As(III)/(V) ratio can be up to 100 times higher in the lower part of the basins. An estimation of the As(III) load transported by both rivers into the Atlantic Ocean has been performed, resulting in about 60 kg yr{sup -1} and 2.7 t yr{sup -1} by the Tinto and Odiel rivers, respectively. - Total arsenic concentration decreases along the water basins, however the As(III)/(V) ratio increases.

    Acid mine drainage in the Iberian Pyrite Belt is probably the worst case in the world of surface water pollution associated with mining of sulphide mineral deposits. The Iberian Pyrite Belt is located in SW Iberian Peninsula, and it has been mined during the last 4,500 years. The central and eastern part of the Iberian Pyrite Belt is drained by the Tinto and Odiel rivers, which receive most of the acidic leachates from the mining areas. As a result, the main channels of the Tinto and Odiel rivers are very rich in metals and highly acidic until reaching the Atlantic Ocean. A significant amount of the pollutant load transported by these two rivers is delivered during the rainy season, as is usual in rivers of Mediterranean climate regions. Therefore, in order to have an accurate estimation of the pollutant loads transported by the Tinto and Odiel rivers, a systematic sampling on a weekly basis and a high temporal resolution sampling of floods events were both performed. Results obtained show that metal fluxes are strongly dependent on the study period, highlighting the importance of inter-annual studies involving dry and wet years.

    Chemolithotrophic communities that colonize subsurface habitats have great relevance for the astrobiological exploration of our Solar System. We hypothesize that the chemical and thermal stabilization of an environment through microbial activity could make a given planetary region habitable. The MARTE project ground-truth drilling campaigns that sampled cryptic subsurface microbial communities in the basement of the Ro Tinto headwaters have shown that acidic surficial habitats are the result of the microbial oxidation of pyritic ores. The oxidation process is exothermic and releases heat under both aerobic and anaerobic conditions. These microbial communities can maintain the subsurface habitat temperature through storage heat if the subsurface temperature does not exceed their maximum growth temperature. In the acidic solutions of the Ro Tinto, ferric iron acts as an effective buffer for controlling water pH. Under anaerobic conditions, ferric iron is the oxidant used by microbes to decompose pyrite through the production of sulfate, ferrous iron, and protons. The integration between the physical and chemical processes mediated by microorganisms with those driven by the local geology and hydrology have led us to hypothesize that thermal and chemical regulation mechanisms exist in this environment and that these homeostatic mechanisms could play an essential role in creating habitable areas for other types of microorganisms. Therefore, searching for the physicochemical expression of extinct and extant homeostatic mechanisms through physical and chemical anomalies in the Mars crust (i.e., local thermal gradient or high concentration of unusual products such as ferric sulfates precipitated out from acidic solutions produced by hypothetical microbial communities) could be a first step in the search for biological traces of a putative extant or extinct Mars biosphere.

    The Tinto River is an extreme case of pollution by acid mine drainage (AMD), with pH values below 3 and high sulphate, metal and metalloid concentrations along its main course. This study evaluates the impact of releases from a freshwater reservoir on the Tinto River, identifying the metal transport mechanisms. This information is needed to understand the water quality evolution in the long term, and involves the comprehension of interactions between AMD sources, freshwaters, particulate matter and sediments. This work proposes a methodology for quantifying the proportions in which the different sources are contributing. The method is based on the mass balance of solutes and accounts for the uncertainty of end-members. The impact of the releases from the Corumbel Reservoir on the hydrochemistry of the Tinto River was significant, accounting up to a 92% of river discharge. These releases provoked a sharp decrease in dissolved metal concentrations, especially for Fe (approximately 1000 fold) due to dilution and precipitation. Cadmium, Zn, Cu, Co, Ni and Al suffered a dilution to a 12-16 fold decrease while Ca, Sr, Na, Pb and Si were less affected (2-4 folds decrease). However, these releases also gave rise to an increase in particulate transport, mainly Fe, As, Cr, Ba, Pb and Ti, due to sediment remobilisation and Fe precipitation. Aluminium, Li, K, Si, Al, Ni and Sr, together with Cu were present in the particulate phase during the discharge peak. The proposed 2-component mixing model revealed the existence of non-conservative behaviour for Al, Ca, Li, Mn, Ni and Si as a consequence of the interactions between the acidic Tinto waters and the clay-rich reservoir sediments during the bottom outlet opening. These results were improved by a 3-component mixing model, introducing a new end-member to account the chemical dissolution of clay-rich sediments by acidic Tinto waters. - Highlights: Black-Right-Pointing-Pointer We study the influence of freshwater releases on the

    Full Text Available Este trabalho visa investigar os possíveis mecanismos moleculares de ação dos polifenóis de uvas e vinho tinto contra os processos oxidativos e inflamatórios envolvidos na aterosclerose. Trata-se de um estudo de revisão de literatura realizado por meio de buscas nas bases de dados PubMed e ScienceDirect utilizando os seguintes descritores: vinho tinto, uva, polifenóis, resveratrol, aterosclerose, LDL-oxidada, inflamação, estresse oxidativo, NF-kB, AP-1, Nrf2, SIRT-1, MicroRNA. Embora tais mecanismos ainda não estejam totalmente esclarecidos, os estudos indicam que compostos fenólicos presentes em uvas podem se complexar com metais (como ferro e cobre que provocam peroxidação dos lipídios, aumentam a atividade antioxidante do plasma, associam-se com a LDL-c aumentando sua resistência à oxidação, preservam a atividade da enzima paraoxonase, neutralizam radicais livres, e ativam fatores de transcrição como o Nrf2, que aumenta a expressão de genes que codificam proteínas importantes na defesa antioxidante, como a superóxido dismutase e a glutationa peroxidase. Além disso, os polifenóis inibem a fosforilação de MAP quinases, inibindo assim os fatores de transcrição NF-kB e AP-1 e, consequentemente, reduzindo a síntese do TNF-á, interleucinas, moléculas de adesão e quimiocinas. Também inibem a atividade das enzimas cicloxigenase e lipoxigenase. Outro mecanismo proposto é a ação do resveratrol sobre a atividade de deacetilases de histonas, como a SITR-1. Estas ações em conjunto reduzem a oxidação da LDL-c e o processo inflamatório, atenuando o processo aterogênico.

    Full Text Available For decades, success in postsecondary education has preoccupied psychological and educational researchers. In this respect, Tinto's student integration model (1982, 1997 is one of the most frequently cited models. Tinto proposed that students' background characteristics, initial intentions and aspirations towards college influence their academic and social integration, which in turn affect their persistence. Unfortunately, although this model is an integrative one, it does not take motivational variables such as students' self-efficacy (Bandura, 1997; Bong & Skaalvik, 2003 and students' subjective value of academic tasks (Eccles & Wigfield, 2002; Neuville, 2004 into account although their impact on learning has been widely demonstrated (Robbins, Lauver, Le, Davis, & Langley, 2004. The purpose of this study, conducted with 2637 first-year university students from all the Bachelor's degree programs of a Belgian university, is to compare, through structural equation models, the explanatory power of these two research traditions (students' integration, on the one hand, and a motivational paradigm, on the other hand in predicting students' academic performance.

    The subsurface is the key environment for searching for life on planets lacking surface life. Subsurface ecosystems are of great relevance to astrobiology including the search for past/present life on Mars. The surface of Mars has conditions preventing current life but the subsurface might preserve organics and even host some life [1]. The Mars-Analog-Rio-Tinto-Experiment (MARTE) is performing a simulation of a Mars drilling experiment. This comprises conventional and robotic drilling of cores in a volcanically-hosted-massive-pyrite deposit [2] from the Iberian Pyritic Belt (IBP) and life detection experiments applying anti-contamination protocols (e.g., ATP Luminometry assay). The RT is considered an important analog of the Sinus Meridiani site on Mars and an ideal model analog for a deep subsurface Martian environment. Former results from MARTE suggest the existence of a relatively complex subsurface life including aerobic and anaerobic chemoautotrophs and strict anaerobic methanogens sustained by Fe and S minerals in anoxic conditions. A key requirement for the analysis of a subsurface sample on Mars is a set of simple tests that can help determine if the sample contains organic material of biological origin, and its potential for retaining definitive biosignatures. We report here on the presence of bulk organic matter Corg (0.03-0.05 Wt%), and Ntot (0.01-0.04 Wt%) and amount of measured ATP (Lightning MVP, Biocontrol) in weathered rocks (tuffs, gossan, pyrite stockwork from Borehole #8; >166m). This provides key insight on the type of trophic system sustaining the subsurface biosphere (i.e., heterotrophs vs. autotrophs) at RT. ATP data (Relative-Luminosity-Units, RLU) provide information on possible contamination and distribution of viable biomass with core depth (BH#8, and BH#7, ~3m). Avg. 153 RLU, i.e., surface vs. center of core, suggest that cleaness/sterility can be maintained when using a simple sterile protocol under field conditions. Results from this

Os SHR receberam 3,715 ml/kg/dia de vinho. O desempenho físico foi analisado por teste de esforço (TE, e a FEVE foi obtida por medidas ecocardiográficas. A aferição da PAS ocorreu antes e após o protocolo do EF. RESULTADOS: Demonstrou-se redução significativa da PAS nos grupos de intervenção, comparados ao GC. Ao final do protocolo, o GVE apresentou a maior redução. Assim como na PAS, o GVE apresentou melhor resultado nos níveis de HDL. Não houve diferença significativa no desempenho físico e na FEVE entre os grupos. CONCLUSÃO: O EF associado à ingesta moderada de vinho tinto exerce efeito cardioprotetor na PAS e na HDL de SHR. O desempenho físico e a FEVE não são alterados.

    Full Text Available Os vinhos tintos, no Brasil, são muito apreciados pelos consumidores das regiões de clima tropical, pelo fato de apresentar tipicidade aromática e paladar frutado. Nesse sentido, o objetivo desse artigo é verificar a qualidade de três vinhos tintos provenientes de vinícolas da região noroeste do estado de São Paulo, através da relação entre determinações físico-químicas e atributos sensoriais. Três vinhos dessa região foram avaliados por meio de métodos analíticos e sensoriais e foi possível observar diferenças significativas nas determinações acidez fixa, teor alcoólico, teor de fenólicos totais e extrato seco. A análise multidimensional mostrou a interação do teor de fenólicos totais com a adstringência, a relação do extrato seco total com o corpo da bebida a relação da acidez volátil na avaliação do odor das amostras. Foi possível constatar a influência físico-química na avaliação dos atributos sensoriais, evidenciando a importância do perfil químico na elucidação de possíveis alterações sensoriais nos vinhos tintos.

    Since its discovery, only few years ago, subsurface geomicrobiology is a matter of growing interest [1]. From a fundamental point of view, it seeks to determine whether life can be sustained in the absence of radiation. From an astrobiological point of view, it is an interesting model for life in other planetary bodies, e.g., Mars, as well as early life on Earth. Río Tinto is an unusual extreme acidic environment due to its size (around 100 km), constant acidic pH (mean pH 2.3), high concentrations of heavy metals and high level of microbial diversity [2]. Río Tinto rises in the core of the Iberian Pyritic Belt, one of the biggest sulfidic ore deposits in the world [3]. Today it is well stablished that the extreme characteristics of Río Tinto are not due to acid mine drainage from mining activity, as has been suggested in the past. To explore the hypothesis that a continuous underground reactor of chemolithotrophic microorganisms thriving in the rich sulfidic minerals of the Iberian Pyritic Belt is responsible for the extreme conditions found in the system, a drilling project has been developed to detect evidence of subsurface microbial activity and potential resources to support these microbial communities in situ (MARTE project) [4]. Here we report a search for subsurface life in volcanically hosted massive sulfidic deposits from the Iberian Pyritic Belt. Aseptic core samples were obtained within and down-gradient from the massive sulfide deposits and formation water was sampled within the resulting bore holes. Microbial activity was detected in un-contaminated samples by culture-dependent and culture-independent methods. Aerobic iron- and sulfide- oxidizing bacteria, and anaerobic denitrifying thiosulfate-oxidizing bacteria, sulfate reducing bacteria and methanogenic archaea have been identified. Potential energy fluxes detected in the system include oxidation of reduced iron and sulfur, or hydrogen gas coupled to nitrite, sulfate, ferric iron, inorganic

    Conclusões: existe uma relação inversa entre a mortalidade por doença arterial coronariana e o consumo de alimentos ricos em flavonóides. Os flavonóides do vinho tinto exerceram ação antioxidante mais eficaz que os do suco de uva, tanto em seres humanos quanto em animais, reduzindo a oxidação do colesterol LDL. O suco de uva mostrou eficácia em alguns estudos, diminuindo o desenvolvimento da placa lipídica, porém em outros estudos houve controvérsias. É fundamental que sejam realizados estudos longitudinais com o suco de uva, para que se possa chegar a um resultado mais esclarecedor em relação ao seu benefício como antioxidante

    2003-01-01

    Full Text Available The study area covers part of the mangrove belt located around Guanabara Bay, Rio de Janeiro, Brazil. Representing a continental-marine transition, the mangrove ecosystem is very susceptible to environmental variations and impacts. The vegetation cover plays an important role in prevention of erosion and contamination processes in those areas. An ongoing extensive research effort in the Petrochemical Complex of Duque de Caxias, Rio de Janeiro State, Brazil, focuses on the man-induced changes in the physical environment (soils, groundwater flow system, type and volumes of contaminants, geochemical aspects and the consequences on the neighboring mangrove ecosystem. This article describes the importance of hydrogeological studies in mangrove areas as part of an appropriate environmental assessment, taking as an example an industrial dumping area located in that Petrochemical Complex. Field work included extensive drilling and sampling to obtain basic geological and hydrogeological parameters and data in the pilot area, such as hydraulic conductivity and piezometric heads; emphasizing the tracking of possible contamination by industrial effluents and the marine influence; validation of the conceptual model with mathematical models (numerical and analytical models was carried out. Results show the great importance of well conducted and detailed hydrogeological studies to properly address environmental problems caused by industrial plants in mangrove areas.

    Full Text Available This study was based on a preliminary survey and inventory of existing reforestation programs in Rio de Janeiro state, through geoprocessing techniques and collection of field data. The reforested area was found to occupy 18,426.96 ha, which amounts to 0.42% of the territory of the state. Much of reforestation programs consists of eucalyptus (98%, followed by pine plantations (0.8%, and the remainder is distributed among 10 other species. The Médio Paraíba region was found to contribute the most to the reforested area of the state (46.6%. The estimated volume of eucalyptus timber was nearly two million cubic meters. This study helped crystallize the ongoing perception among those militating in the forestry sector of Rio de Janeiro state that the planted area and stock of reforestation timber is still incipient in the state.

Foram encontradas poucas amostras com características inteiramente satisfatórias, notando-se, principalmente, deficiências de clarificação e de filtração. Das 15 marcas de vinhos brancos, só três se apresentaram perfeitamente brilhantes, e sete, ligeira ou completamente turvos. Nos tintos, em geral, foi maior a turbidez. Verificou-se, também, a presença, entre os brancos, de vinhos com acidez volátil acima do limite permitido pela legislação brasileira. Foi notada a ausência de anidrido sulfuroso total e livre. Os resultados dos outros componentes mostraram-se, todavia, bastante satisfatórios. Foram ainda observados o comprimento insuficiente das rôlhas para garantir a boa conservação do vinho, e a desuniformidade das garrafas quanto a tipo, forma, capacidade e côr.Fifteen hrands of white and 15 of red wines were collected from groceries for analysis and flavor tests. Very few samples were satisfactory. Most of the wines had been poorly clarified and filtered. Only three of the 15 samples of white wines were brilliant; seven were classified as slightly cloudy or cloudy. Cloudiness was higher among the red wines. Two samples of the white wines had a high volatile acidity, above the limit permitted by the Brazilian regulation. Lack af free and total sulfur dioxide was observed. As far as the other wines constituents are concerned, all analysed samples were satisfactory. The corks utilized were generally shorter than it is desirable to seal the bottles satisfactorily. Also, the bottles were not uniform in type, shape, capacity, and color.

    Full Text Available Insect galls of restinga areas of Ilha da Marambaia, Rio de Janeiro, Brazil. This study carried out an insect gall inventory in restinga areas of Ilha da Marambaia, in the municipality of Mangaratiba, Rio de Janeiro, Brazil. Sampling was carried out monthly from April 2010 to March 2011 along the full extension of seven beaches. A total number of 147 gall morphotypes associated with 70 plant species were found, distributed in 33 plant families, and at least 54 genera. Myrtaceae was the botanical family with the highest richness of gall morphotypes and host species, followed by Bignoniaceae, Fabaceae, Asteraceae, Euphorbiaceae, Sapindaceae, and Malpighiaceae. Most of the gall morphotypes occurred in leaves (78 morphotypes, 38 in stems, 14 in flowers, eight in buds and fruits, and one in adventitious roots. The galling insects belong to the five orders: Diptera, Coleoptera, Hemiptera, Lepidoptera, and Thysanoptera. Cecidomyiidae (Diptera was the most common galling taxon (78 morphotypes, represented by 87 species, being 78 gallers, seven inquilines and two predators. In addition to the gallers, parasitoids, inquilines, and predators were also found.

    Full Text Available The order Asparagales comprises 14 families, five of which occur in Brazil. Amaryllidaceae is a family of economic relevance and includes numerous ornamental genera. The genus Hippeastrum is widely distributed in Brazil and comprises 34 species, 11 of which occur in areas of restinga (coastal woodland and Atlantic Forest in the state of Rio de Janeiro. The morphology of Hippeastrum has not been extensively studied in Brazil, where only a few systematic floristic surveys have been carried out with native species. In field studies and reviews of herbarium collections, we identified five Hippeastrum species occurring in areas of restinga in the state of Rio de Janeiro. The five species identified could be distinguished according to the following palynological characteristics: pollen grain size, polarity, pollen units, shape, aperture (number and type, exine sculpture, colpus length and pattern of sexine ornamentation. Of the five species identified, Hippeastrum aulicum Herb. and H. glaucescens (Ker Gawl. Herb. were not identified in the field. Among the three species that were found in the field, H. striatum had the widest distribution in the study area, whereas the distribution of H. reticulatum was restricted to a single area of restinga, in the Jaconé district of the municipality of Saquarema. Through palynological examinations of specimens from herbaria in the state of Rio de Janeiro, we were able to confirm the identity of all five species of Hippeastrum studied. Our data represent a relevant contribution to increasing knowledge of this plant group in the region and will aid in future conservation efforts.

    The Tinto River estuary is highly polluted with the acid lixiviates from old sulphide mines. In this work the behaviour of dissolved and particulate trace metals under strong chemical gradients during a tidal cycle is studied. The pH values range from 4.4 with low tide to 6.9 with high tide. Precipitation of Fe and Al is intense during rising tides and As and Pb are almost exclusively found in the particulate matter (PM). Sorption processes are very important in controlling the mobility (and hence bioavailability) of some metals and particularly affect Cu below pH 6. Above pH ∼ 6 Cu is desorbed, probably by the formation of Cu(I)–chloride complexes. Although less pronounced than Cu, also Zn desorption above pH 6.5 seems to occur. Mn and Co are affected by sorption processes at pH higher than ca. 6. Cd behaves conservatively and Ni is slightly affected by sorption processes. - Highlights: • The Tinto estuary shows strong pH gradients and high trace elements concentrations. • PM has a hysteretic relationship with tides and high contents of Fe, Al, As and Pb. • Co and Mn are controlled by river and sea water mixing and sorption processes. • Sorption processes strongly affect Cu below pH 6, above this value Cu is desorpted. • Cadmium behaves conservatively along the pH range studied (4.4–6.9)

    Settlement and deforestation surrounding the Brazilian town of Rio Branco are seen here in the striking 'herring bone' deforestation patterns that cut through the rainforest. Rio Brancois the capital of the Brazilian state of Acre and is situated near the border with northeastern Bolivia. The town is a center for the distribution of goods, including rubber, metals, medicinal plants, Brazil nuts and timber. Colonization projects in the region are supported by farming, logging activities, and extensive cattle ranching. Much of the surrounding terrain is of a poorly-draining clay hardpan soil, and heavy rainfall periodically converts parts of the forested region to swamp.The large overview image was acquired by the Multi-angle Imaging SpectroRadiometer's vertical-viewing (nadir) camera on July 28, 2000, and covers an area of 336 kilometers x 333 kilometers. A plume of smoke is visible north of the Rio Branco road, which roughly parallels the slender, twisting Rio Abuna. Most of the major rivers in the image provide reference points for state or international (Bolivia-Brazil) boundaries, and flow northeast to the Rio Madeira (east of the smoke plume). The border between Acre and the Bolivian department of Pando is marked by the Rio Abuna. Pando's southern boundary with the department of Beni is marked by the Rio Madre de Dios, the large river in the lower half of the image.The two higher-resolution inset images highlight a settled area north of the town of Rio Branco. These nadir views cover an area of 60 kilometers x 67 kilometers, and were acquired eleven months apart during Terra orbits 3251 and 8144. In the later image, more haze is present, possibly due to smoke from fires on that day. Comparing the two images provides a method of measuring the changes and expansion in the area of cleared land. One newly cleared patch is apparent near the middle of the later image, slightly off to the right. This polygon represents an area of about 16 square kilometers, or 4000

We characterized the biomolecular patterns recorded in samples of modern and old fluvial sediments along a segment of the river by means of an antibody microarray containing more than 200 antibodies (LDCHIP200, for Life Detector Chip) against whole microorganisms, universal biomolecules, or environmental extracts. Samples containing 0.3-0.5g of solid material were automatically analyzed in situ by the Signs Of LIfe Detector instrument (SOLID2), and the results were corroborated by extensive analysis in the laboratory. Positive antigen-antibody reactions indicated the presence of microbial strains or high-molecular-weight biopolymers that originated from them. The LDCHIP200 results were quantified and subjected to a multivariate analysis for immunoprofiling. We associated similar immunopatterns, and biomolecular markers, to samples with similar sedimentary age. Phyllosilicate-rich samples from modern fluvial sediments gave strong positive reactions with antibodies against bacteria of the genus Acidithiobacillus and against biochemical extracts from Río Tinto sediments and biofilms. These samples contained high amounts of sugars (mostly polysaccharides) with monosaccharides like glucose, rhamnose, fucose, and so on. By contrast, the older deposits, which are a mix of clastic sands and evaporites, showed only a few positives with LDCHIP200, consistent with lower protein and sugar content. We conclude that LDCHIP200 results can establish a correlation between microenvironments, diagenetic stages, and age with the biomarker profile associated with a sample.

    Information on the presence of clay-rich layers in the inner-valley alluvium is essential for quantifying the amount of water transmitted between the Rio Grande and the Santa Fe Group aquifer system. This report describes a study that used electromagnetic surveys to provide this information. In the first phase of the study, electromagnetic soundings were made using time-domain and frequency-domain electro- magnetic methods. On the basis of these initial results, the time- domain method was judged ineffective because of cultural noise in the study area, so subsequent surveys were made using the frequency-domain method. For the second phase of the study, 31 frequency-domain electromagnetic surveys were conducted along the inner valley and parallel to the Rio Grande in the Albuquerque area in the spring and summer of 1997 to determine the presence of hydrologically significant clay-rich layers buried in the inner-valley alluvium. For this report, the 31 survey sections were combined into 10 composite sections for ease of interpretation. Terrain-conductivity data from the surveys were modeled using interpretation software to produce geoelectric cross sections along the survey lines. This modeling used lithologic logs from two wells installed near the survey lines: the Bosque South and Rio Bravo 5 wells. Because of cultural interference, location of the wells and soundings, complex stratigraphy, and difficulty interpreting lithology, such interpretation was inconclusive. Instead, a decision process based on modeling results was developed using vertical and horizontal dipole 40-meter intercoil spacing terrain-conductivity values. Values larger than or equal to 20 millisiemens per meter were interpreted to contain a hydrologically significant thickness of clay-rich sediment. Thus, clay-rich sediment was interpreted to underlie seven segments of the 10 composited survey lines, totaling at least 2,660 meters of the Rio Grande inner valley. The longest of these clay

    Iberian Pyrite Belt Subsurface Life (IPBSL) is a drilling project specifically designed to characterize the subsurface ecosystems operating in the Iberian Pyrite Belt (IPB), in the area of Peña de Hierro, and responsible of the extreme acidic conditions existing in the Rio Tinto basin [1]. Rio Tinto is considered a good geochemical terrestrial analogue of Mars [2, 3]. A dedicated geophysical characterization of the area selected two drilling sites (4) due to the possible existence of water with high ionic content (low resistivity). Two wells have been drilled in the selected area, BH11 and BH10, of depths of 340 and 620 meters respectively, with recovery of cores and generation of samples in anaerobic and sterile conditions. Preliminary results showed an important alteration of mineral structures associated with the presence of water, with production of expected products from the bacterial oxidation of pyrite (sulfates and ferric iron). Ion chromatography of water soluble compounds from uncontaminated samples showed the existence of putative electron donors (ferrous iron, nitrite in addition of the metal sulfides), electron acceptors (sulfate, nitrate, ferric iron) as well as variable concentration of metabolic organic acids (mainly acetate, formate, propionate and oxalate), which are strong signals of the presence of active subsurface ecosystem associated to the high sulfidic mineral content of the IPB. The system is driven by oxidants that appear to be provided by the rock matrix, only groundwater is needed to launch microbial metabolism. The geological, geomicrobiological and molecular biology analysis which are under way, should allow the characterization of this ecosystem of paramount interest in the design of an astrobiological underground Mars exploration mission in the near future.

    Lutzomyia longipalpis is the main vector of Leishmania infantum chagasi in the Americas. Phlebotomine captures were conducted during 2008 and 2009 in a rural area endemic for cutaneous leishmaniasis located in the municipality of Saquarema, Rio de Janeiro. Among other species captured, we observed the presence of Lutzomyia longipalpis. This is the first report of the occurrence of Lutzomyia longipalpis in this region, demonstrating the potential risk of visceral leishmaniasis transmission in the coastal area of the State of Rio de Janeiro. Therefore, active vigilance by all municipalities in the area is necessary.

    The Rio Cristalino area where occurs uranium mineralization is located in the Western part of the Santana do Araguaia Town, Para State. This area comprises 1.350 Km 2 , and was selected from the evolution of the 'Projeto Geofisico Brasil - Canada - PGBC'. According to the results obtained from this Project, 15 airbone anomalies were selected for ground check. In the anomalies AN-03 and H-09 were found the best uranium occurence. The host rocks consist of arkose and sandstone of Pre-Cambriam ages, which show a very low-grade of metamorphism. The primary mineralization occurs in arkose along the cataclastic foliation (N70 0 W / 65 0 NE). The secundary mineralization involves clay galls and fills fracture zones in sandstone of the anomaly H-09. The highest grade detected in a rock sample of the anomaly AN-03 was 6,1% U 3 O 8 , whereas in the trenches there are intervals of 6 m thickness with a grade of 0,59% U 3 O 8 . Based on some mineralization aspects and field data, the genetic conceptual model to the uranium mineralization is proposed. (author) [pt

    The Río Tinto (RT) is distinguished from other acid mine drainage systems by its natural and ancient origins. Microbial life from all three domains flourishes in this ecosystem, but bacteria dominate metabolic processes that perpetuate environmental extremes. While the patchy geochemistry of the RT likely influences the dynamics of bacterial populations, demonstrating which environmental variables shape microbial diversity and unveiling the mechanisms underlying observed patterns, remain major challenges in microbial ecology whose answers rely upon detailed assessments of community structures coupled with fine-scale measurements of physico-chemical parameters. By using high-throughput environmental tag sequencing we achieved saturation of richness estimators for the first time in the RT. We found that environmental factors dictate the distribution of the most abundant taxa in this system, but stochastic niche differentiation processes, such as mutation and dispersal, also contribute to observed diversity patterns. We predict that studies providing clues to the evolutionary and ecological processes underlying microbial distributions will reconcile the ongoing debate between the Baas Becking vs. Hubbell community assembly hypotheses.

    A team from the Remote Sensing Laboratory in Las Vegas, Nevada, conducted an aerial radiation survey of the area surrounding ground zero of Project Rio Blanco in the northwestern section of Colorado in June 1993. The object of the survey was to determine if there were man-made radioisotopes on or near the surface resulting from a nuclear explosion in 1972. No indications of surface contamination were found. A search for the cesium-137 radioisotope was negative. The Minimum Detectable Activity for cesium-137 is presented for several detection probabilities. The natural terrestrial exposure rates in units of Roentgens per hour were mapped and are presented in the form of a contour map over-laid on an aerial photograph. A second team made independent ground-based measurements in four places within the survey area. The average agreement of the ground-based with aerial measurements was six percent

    Full Text Available Abstract: Recently, Brazil has hosted mass events with recognized international relevance. The 2014 FIFA World Cup was held in 12 Brazilian state capitals and health sector preparedness drew on the history of other World Cups and Brazil's own experience with the 2013 FIFA Confederations Cup. The current article aims to analyze the treatment capacity of hospital facilities in georeferenced areas for sports events in the 2016 Olympic Games in the city of Rio de Janeiro, based on a model built drawing on references from the literature. Source of data were Brazilian health databases and the Rio 2016 website. Sports venues for the Olympic Games and surrounding hospitals in a 10km radius were located by geoprocessing and designated a "health area" referring to the probable inflow of persons to be treated in case of hospital referral. Six different factors were used to calculate needs for surge and one was used to calculate needs in case of disasters (20/1,000. Hospital treatment capacity is defined by the coincidence of beds and life support equipment, namely the number of cardiac monitors (electrocardiographs and ventilators in each hospital unit. Maracanã followed by the Olympic Stadium (Engenhão and the Sambódromo would have the highest single demand for hospitalizations (1,572, 1,200 and 600, respectively. Hospital treatment capacity proved capable of accommodating surges, but insufficient in cases of mass casualties. In mass events most treatments involve easy clinical management, it is expected that the current capacity will not have negative consequences for participants.

The area is located between the cities of Campo Magro and Campo Largo, Paraná plateau in the first part of theAlto Iguaçu basin. This study aims to raise the concepts relating to environmental geomorphology, to identify the anthropogenic impacts caused in the reservoir areas, identify the environmental compartments found around the dam and characterize the geologic and physiographic region. It was found that the area has intense anthropogenic influence, as urban growth is present in areas and wavy and rough terrain, subject to mass movements and floods. Besides these aspects, the use of land for agriculture contributes to fragility of the area.

    Full Text Available This work focuses on Neoproterozoic supracrustal rocks related to Andrelandia megasequence, which are superimposed on the basis represented by neoarchean granulites and palaeoproterozoic ortogneiss, in order to define palaeoenvironments of deposition of metasedimentary rocks and typological model of zinc mineralization of Rio Claro, Rio de Janeiro State, SE of Brazil. Three stratigraphic units in the area were considered for the studies: Valadão, São Roque and Lidice. Valadão unit was divided into three subunits: psamitic, psamitic / pelitic and pelitic. On the whole, it represents a turbiditic sequence influenced by underwater hydrothermal exhalations that led to the formation of quartzite with magnetite, considered as banded iron formations. São Roque Unit is composed of four subunits (São Roque I, II, III and IV and presents a typical pattern of deposition of low energy environments, in marine deep basins. Gondite, coticules levels and (Mn-almandine present in the local gneiss mark the manganese exalative contribution in that unit. Lídice unit has different sedimentation palaeoenvironments and is subdivided into Lídice I, II and III. Lídice subunits I and II exhibit quartzite interleaved with pelitic rocks and graphite gneiss, suggesting deposition in deeper environments of the basin, probably related to turbidity currents. In Lídice III subunit, more carbonated and with more quartz, limestone quartzite stand out, which enclose mineralized zones, reflecting depositional environment in shallow platform, possibly involving evaporitic environment, sabkha type. Sulfite mineralization of Rio Claro, associated with platformal rocks intensely metamorphosed and deformed, as well as its local geological context, features similarities with sedimentary exhalative deposits (SEDEX Zn-Pb-Ag model, Shuswap and Monashee type, present in Monashee and Shuswap Complexes of British Columbia in Canada.

    The Rio Torto area, on the northern slope of the Tosco-Emiliano Apennine, in the C.R. Enea Brasimone property, has been the object of a research study on flora and vegetation to delineate the vegetal coverage and to evaluate the vegetal population changes. The study on vegetation has been carried out using the Braun-Blanquet method, a flora-statistical approach based on an accurate analysis of the flora and on statistical sampling of the studied object. Data has been analysed using the SYN-TAX-Multivariate Data Analysis software package, in order to get out a classification and, therefore, some syn-taxonomic levels in vegetation. Result is a dendogram with clusters connected by transverse lines and organised in a Hierarchical Clustering system. The dominant species in the Rio Torto area is beech; elements of the Arrhenatheretalia association are well-represented at the lower edge of the wood, while a broad glade characterised by Pteridium aquilinum (L.) Kuhn, by Prunus spinosa L. and by Crataegus monogyna Jacq is at the upper edge. Grassy undergrowth is dominated by Eurasian and boreal elements and, from a physiognomic-structural point of view, is quite rich. The biological spectrum analysis points up the particularly high value of the hemicryptophytes: this result couldn't be justified by the mountainous nature of the zone but it could be considered a sign of stress. From the vegetation and phytosociological study, a classification of the beech population on the basis of the complex of characteristics is gained; in this classification, the beech population is fitted in the order Fagetalia Pawl, 1928 (Ubaldi and Speranza, 1985) and in the alliance Fagion Sylvaticae medioeuropeo (Luquet 1926) Tx and Diemont 1936. No particular association has been identified within the alliance, because is not possible to detect a species well-defined contingent.

    The U.S. Geological Survey, in cooperation with the International Boundary and Water Commission - U.S. and Mexican Sections, the National Park Service, the Texas Commission on Environmental Quality, the Secretaria de Medio Ambiente y Recursos Naturales in Mexico, the Area de Proteccion de Flora y Fauna Canon de Santa Elena in Mexico, and the Area de Proteccion de Flora y Fauna Maderas del Carmen in Mexico, collected samples of stream water, streambed sediment, and mine tailings during August 2002 for a study to determine whether trace elements from abandoned mines in the area in and around Big Bend National Park have affected the water and sediment quality in the Rio Grande/Rio Bravo Basin of the United States and Mexico. Samples were collected from eight sites on the main stem of the Rio Grande/Rio Bravo, four Rio Grande/Rio Bravo tributary sites downstream from abandoned mines or mine-tailing sites, and 11 mine-tailing sites. Mines in the area were operated to produce fluorite, germanium, iron, lead, mercury, silver, and zinc during the late 1800s through at least the late 1970s. Moderate (relatively neutral) pHs in stream-water samples collected at the 12 Rio Grande/Rio Bravo main-stem and tributary sites indicate that water is well mixed, diluted, and buffered with respect to the solubility of trace elements. The highest sulfate concentrations were in water samples from tributaries draining the Terlingua mining district. Only the sample from the Rough Run Draw site exceeded the Texas Surface Water Quality Standards general-use protection criterion for sulfate. All chloride and dissolved solids concentrations in water samples were less than the general-use protection criteria. Aluminum, copper, mercury, nickel, selenium, and zinc were detected in all water samples for which each element was analyzed. Cadmium, chromium, and lead were detected in samples less frequently, and silver was not detected in any of the samples. None of the sample concentrations of

From the vegetation and phytosociological study, a classification of the beech population on the basis of the complex of characteristics is gained; in this classification, the beech population is fitted in the order Fagetalia Pawl, 1928 (Ubaldi and Speranza, 1985) and in the alliance Fagion Sylvaticae medioeuropeo (Luquet 1926) Tx and Diemont 1936. No particular association has been identified within the alliance, because is not possible to detect a species well-defined contingent. Ecologically more demanding species absence and non-characteristic entities intrusion is linked to the general state

    Full Text Available SUMMARY American tegumentary leishmaniasis (ATL is an infectious disease caused by protozoa of the genus Leishmania, and transmitted by sandflies. In the state of Rio de Janeiro, almost all of the cases of American tegumentary leishmaniasis (ATL are caused by Leishmania (Viannia braziliensis, while cases of visceral leishmaniasis (VL are caused by Leishmania (Leishmania infantum chagasi. The resurgence of autochthonous VL cases in Rio de Janeiro is related to the geographic expansion of the vector Lutzomyia longipalpis and its ability to adapt to urban areas. We report the first case of leishmaniasis with exclusively cutaneous manifestations caused by L. (L. infantum chagasi in an urban area of Rio de Janeiro. An eighty-one-year-old woman presented three pleomorphic skin lesions that were not associated with systemic symptoms or visceromegalies. Multilocus enzyme electrophoresis identified L. (L. infantum chagasi, but direct smear and PCR of bone narrow were negative for Leishmania sp. (suggesting exclusively cutaneous involvement. We discuss the different dermatological presentations of viscerotropic leishmaniasis of the New and Old World, and the clinical and epidemiological importance of the case. Etiologic diagnosis of ATL based upon exclusive clinical criteria may lead to incorrect conclusions. We should be aware of the constant changes in epidemiological patterns related to leishmaniases.

  20. In Rio de Janeiro public entrance areas disappeared behind railings out of fear of crime

    Full Text Available The need for safety leads to an increasing fencing of entrance areas and to a structural spatial segregation in Rio de Janeiro. Today’s passerby moves along high grids instead of walking on lavishly planted ways along noble entrance areas. In the scale of urban development the stronger variant of spatial demarcation is taking place. Gated communities arise as a total spatial exclusion, in a safe distance to existing favelas and disposing of abundant safety equipment.Precisely because the need for safety is important in dwelling, both trends are problematic from the urban perspective. The increasing fencing and demarcating destroys pleasant urban atmospheres and fosters the spreading of mono-functional resp. mono-social areas. However, trust and a peaceful togetherness are required for a socially and functionally mixed and spatially diversified public space. But these conditions can only be realised in the context of the entire society.

    The effects of industrial anthropization on species composition and community diversity of Culicidae (Diptera) were studied in a mangrove area impacted by industrial activities as compared to a preserved area, both around Guanabara Bay in the state of Rio de Janeiro, Brazil. Diversity, equitability, and species richness in Culicidae community differed between the studied areas. Indicator species analysis and correspondence analysis were carried out and indicated that the Sabethini, especially Wyeomyia (Phoniomyia) theobaldi Lane, Wyeomyia (Phoniomyia) fuscipes (Edwards), and a non-identified species of Wyeomyia sp. were associated to the preserved area, whereas Aedes taeniorhynchus Wiedemann and Aedes scapularis (Rondani) to the impacted area.

    This paper deals with the mining of reworked gossan at Riotinto (Huelva, southwest Spain). The rock in question is a conglomerate formed by the erosion of gossan and its subsequent deposition in areas at some distance from its origin. In Roman times this mineral was used as construction material as well as for architectural decoration and possibly as an ore for making mining tools. This work focuses upon the exploitation of this mineral as an iron ore mined from the site known as Mesa Pinos or Alto de la Mesa by the Rio Tinto Company Ltd. between the last quarter of the 19th century and the first part of the 20th century.

    2005-01-01

    The effects of selected concentrations of Cd on the growth and ultrastructure of three strains of Chlamydomonas sp. isolated from a highly acidic river, Rio Tinto (SW Spain) were examined. The river is characterized by its extreme physico-chemical conditions in terms of low pH, mean 2.2 and high concentrations of heavy metals. Growth, Cd accumulation, chlorophyll a, influence of Fe in Cd toxicity and ultrastructural localization were determined. The strains were cultured in both, artificial chemically defined media as well as in natural water from the river. Since iron is the main component of the river water, the effect of different concentrations of this element in relation with Cd toxicity was also analysed. The three strains analysed showed comparable growth and ultrastructural changes. Cd concentration corresponding to 50% growth inhibition (EC 5 ) was 0.2 mM when cells were grown in artificial media. When cells were grown in natural water, no significant differences were found between the controls and the Cd supplemented media even at the highest concentration of 0.8 mM. At an inhibitory level of 0.1 mM of Cd, increasing the concentration of iron up to 90 or 180 mM resulted in a dramatic recovery in algal growth rates in artificial media, reaching normal growth curves. The accumulation of Cd depended on dose and time in the artificial media. The maximal accumulation of Cd was reached after 3 days for all Cd doses, and remained almost unchanged in the subsequent period of time. Chlorophyll a amount depended on dose but not on time in the artificial growth media. At the ultrastructural level, an increase in the periplasmalemmal space was observed due to the presence of a large number of vacuoles, together with a decrease in the relative volume of the nucleus when the cells were incubated in the presence of Cd. Pyrenoid and starch granules were observed and accumulation of spherical electron-dense bodies were also detected. X-ray spectra of these bodies for

    Uche, Ada Rosemary

    In the current technologically advanced global economy, the role of human capital and education cannot be over-emphasized. Since almost all great inventions in the world have a scientific or technological foundation, having a skilled workforce is imperative for any nation's economic growth. Currently, large segments of the United States' population are underrepresented in the attainment of science, technology, engineering, and math (STEM) degrees, and in the STEM professions. Scholars, educators, policy-makers, and employers are concerned about the decline in student enrollment and graduation from STEM disciplines. This trend is especially problematic for first-generation college students. This study uses both quantitative and qualitative methods to assess the factors that predict the retention of first-generation college students in the STEM majors. It employs Tinto's longitudinal model (1993) as a conceptual framework to predict STEM retention for first-generation college students. The analysis uses the Beginning Post-secondary Students study (BPS 04/09) data and Roots of STEM qualitative data to investigate the role of first-generation status in STEM major retention. Results indicate that upper levels of achievement in high school math have a significant effect on first-generation status in STEM outcomes.

    We propose the use of previously developed small area estimation techniques to monitor obesity and dietary habits in developing countries and apply the model to Rio de Janeiro city. We estimate obesity prevalence rates at the Census Tract through a combinatorial optimization spatial microsimulation model that matches body mass index and socio-demographic data in Brazil's 2008-9 family expenditure survey with Census 2010 socio-demographic data. Obesity ranges from 8% to 25% in most areas and affects the poor almost as much as the rich. Male and female obesity rates are uncorrelated at the small area level. The model is an effective tool to understand the complexity of the problem and to aid in policy design. © 2013 Published by Elsevier Ltd.

    Rio de Janeiro Petrochemical Complex (COMPERJ) will be installed in the north region of Itaborai city. The start of COMPERJ operations is foreseen to 2012. Because of the intensification of industrialization and urbanization processes, the implantation of COMPERJ will bring environmental modifications for Itaborai city and neighbors areas. Thus, meteorological and air quality monitoring was initiated in February of 2007 with the intention of carrying out a characterization of air pollution in this area, before COMPERJ operations. In this work are presented the results found in campaigns performed of February of 2007 until April of 2008. The meteorological monitoring disclosed that the meteorological parameters have varied enough throughout the months, but these are representative of a global behavior of the studied area. Monitoring of air quality has shown that atmospheric levels of monitored pollutants has been generally below of Brazilian air quality standards. This fact corroborates the basic aspect of the present study: identification of the concentrations 'background' in the studied area. Throughout the period of monitoring, the primary air quality standard for ozone has been reached. Observations of meteorological parameters indicate that this fact is associated to the emissions originated from Sao Goncalo, Niteroi and Rio de Janeiro cities. (author)

    GNSS navigation satellites are currently being developed by all major players in the science and technology scene, to compete with the GPS system. Because their applications span many different areas, from traffic and cargo control, to geodesy and seismic monitoring, it is required to assess the coherence between the different constellations. BDS is the GNSS system currently developed in China. Its first generation of satellites consisted of 3 geostationnary satellites allowing geolocalisation in China only. In addition to these satellites, other satellites have been launched in geostationnary and geosynchronous orbits, as well as satellites orbiting with a classical GNSS semi-major axis. With these additions, the BDS system possesses 19 operating satellites, and though the system is mostly efficient for geolocalisation in Asia, the satellites are also visible in other parts of the globe. In parallel to the development of the BDS constellation, China has launched the iGMAS (International GNSS Monitoring and Assessment Service) project to develop a global tracking network of multi-GNSS geodetic receivers. One of the goals of this project is to evaluate the efficiency of the BDS constellation as well as the efficiency of the receivers developed by the Chinese laboratories. As part of the Brazilian program COSBAN leaded by the Foreign Affairs Ministry to foster up the science and technology partnership with China, materialized by the collaboration between the Shanghai Astronomical Observatory/CAS and the Observatório Nacional/MCTI, in Rio de Janeiro. Through it the RIOS-iGMAS station was installed at Observatório Nacional, where the RJEP GNSS station already operates as part of the Brazilian reference system. Thus at the Observatório Nacional can be observed satellites from any constellation with both systems of reception, leading to a direct, efficient way to compare the results obtained for each network.

    During the 40's and 50's there had been a hexachlorocyclohexane(HCH) industry in Duque de Caxias, state of Rio de Janeiro, Brazil. Duque de Caxias is a very important borough within the state's political and administrative structure. It is located in a strategic point connecting Minas Gerais and Rio de Janeiro. It also holds one of Brazil's greatest petroleum refineries. For 20 years, this factory (which is located next to an orphanage called Cidade dos Meninos, an area belonging to the Ministry of Social Assistance) produced thousands of tons of HCH and also other pesticides, such as DDT, DDD and DDE. In the beginning of the 60's, the industry had its activities stopped1. In 1989, significant amounts of HCH had been found by local inspectors in Duque de Caxias, where it had been being sold for use in agriculture. Once the product's usage had already been prohibited in Brazil, after a investigation authorities found that it would come from the inactive industry. Both environmental and public health institutions decided to use a mixture of lime and soil, in order to destroy the residues and organic compounds found in the old plant. Such procedure would cause a greater problem, for the lime used wouldn't meet the right proportions of the large area and its contaminated soil. In addition, it also affected the water supply and the local population. The consequences have been disastrous. Data referring to breastfeeding and blood revealed alarming pesticide rates that endangered the local people health conditions both in short and long term. After 14 years, monitoring is still necessary in that region so it is possible to control contamination and its damage related to secondary reactions, climatic effects and soil structure. For this reason, a monitoring program has been developed in order to investigate the rates of certain pesticides and PCDD/F in locations near the contamination field.

    Full Text Available OBJECTIVE: To evaluate density, parity rates, daily survival and longevity of natural populations of Culex quinquefasciatus in three neighborhoods with distinct socio-economic and infrastructure profiles. METHODS: Mosquito collections of the Culex quinquefasciatus species were performed weekly during two four month periods, from August to November 2008 (spring and March to June 2009 (fall, in a favela (slum, a suburban area and a middle class area of Rio de Janeiro, Southeastern Brazil. Collections were performed with backpack aspirators, in 20 randomly selected houses in each area per week, during 15-20 minutes per house. Ovaries were removed from captured females and classified as initial, intermediary or final stage. Furthermore, females were dissected for determination of parity based on the condition of the tracheal system. Mosquito survival rate and longevity were estimated on a per month basis for each neighborhood. RESULTS: We collected a total of 2,062 Culex quinquefasciatus, but monthly vector density was not correlated with temperature and rainfall. We dissected the ovaries of 625 Culex quinquefasciatus, and overall, there was a higher proportion of nulliparous females during the dryer months, while gravid females were more frequent in rainy months. In the middle class neighborhood, the parity rate reached up to 93.75% with survivorship of 0.979. Lower parity and survival rates were obtained in the suburban area (as low as 36.4% parity and 0.711 daily survival. Up to 84.7% of Culex quinquefasciatus females could survive the eight day period needed to complete West Nile Virus incubation. CONCLUSIONS: The survival rate of Culex quinquefasciatus varied significantly between the neighborhoods. This suggests that vectorial capacity and disease transmission risk may vary greatly between different urban areas, which is potentially useful information for vector control programs.

    The south coast of Rio de Janeiro State, in Brazil, is endemic for cutaneous and visceral leishmaniases and is frequently visited by tourists from different parts of the world. Since the complex epidemiology of leishmaniases demands local studies, the goal of this study was to investigate the phlebotomine sand fly fauna and leishmaniases transmission in Ilha Grande, an ecotourism area of Angra dos Reis municipality. Sand fly fauna was sampled in three monitoring stations using HP light traps in domiciles, peridomiciles and forests. Species abundance was evaluated by the Index of Species Abundance. A Leishmania natural infection survey was done using multiplex PCR and dot blot hybridization. During 15 consecutive months of sand fly monitoring, 1093 specimens from 16 species were captured. The potential leishmaniases vectors found were Lutzomyia (Nyssomyia) intermedia, L. migonei, L. (N.) flaviscutellata, L. (Psychodopygus) ayrozai and L. (Lutzomyia) longipalpis. Five species were new records in Ilha Grande: L. (Sciopemyia) microps, L. termitophila, L. firmatoi, L. rupicola and L. (P.) ayrozai. Higher species richness was found inside forest areas, although potential leishmaniases vectors were present in deforested areas, peridomiciles and inside houses. Lutzomyia (N.) intermedia and L. migonei were the most abundant species. Females of L. migonei showed a high rate (10.3%) of natural infection by Leishmania (Viannia) sp., probably Leishmania (V.) braziliensis. The detection of leishmaniases transmission and potential vectors in Ilha Grande is of public health concern, especially because tourists are frequently visiting the island. Besides reinforcing the epidemiological importance of L. (N.) intermedia in Rio de Janeiro State, the role of L. migonei in cutaneous leishmaniasis transmission is highlighted with its high rate of Leishmania natural infection. The finding of L. (L.) longipalpis confirmed the human autochthonous case of visceral leishmaniasis from the

    In this work, the contribution of evaporative emissions from light passenger vehicles to the degradation of the air quality was investigated on the basis of the indoor quantification of the monoaromatic volatile compounds Benzene, Toluene, Ethylbenzene and Xylenes (BTEX), specifically, a confined shopping mall parking area in the northern zone of Rio de Janeiro, a site that represents the reality of the vehicular fleet of the Metropolitan Region of Rio de Janeiro. In order to evaluate the concentration of the BTEX compounds, samples were collected, by an active sampling system using charcoal cartridge as adsorbent. The samples were extracted with organic solvent and subsequently analyzed by gas chromatography-mass spectrometry (GCMS). The average results were 54.14 μg m-3 (benzene), 209.24 μg m-3 (toluene), 45.87 μg m-3 (ethylbenzene) and 118.93 μg m-3 (xylenes). These results are compared with results from the literature of vehicular emissions in confined spaces such as garages and tunnels. Possible correlations with emissions from moving vehicles, obtained from previous studies in a tunnel of large circulation and emissions obtained in other underground parkings, are also investigated. The results suggest different emission sources.

    The Muskau Arch is situated in the west of Poland and in the east of Germany. This region is a belt formed by push and frontal moraines during the Middle-Polish (Riss) glaciation, especially during the Wartanian glaciation. The occurrence of glacier caused folding and forming the glacitectonic type of lignit deposits which were mined for over 150 years. Both open pit and underground mining methods has exposed metal sulfides (mainly pyrite) to air and water causing bio-oxidation. Due to this process the acidity of many reservoirs have increased significantly (pH values between 2 and 4). As a consequence of changes in the environment, new mineral phases precipitated from highly acid waters rich in, among others, various forms of Fe and S. Precipitation of ochreous minerals such as schwertmannite, goethite and jarosite was partly catalyzed by many various acidophilic and acid-tolerant microorganisms: bacteria, archaea and probably yeasts. Jarosite KFe33+(OH)6(SO4)2 can be precipitated both in abiotic conditions and as a by-product of the activity of living organisms. The example of biomineralization induced by fungi Purpureocillium lilacinum in similar AMD environment of Rio Tinto is reported (Oggerin et al, 2014). Recently, jarosite is also considered as a possible biosignature of life on Mars. The assessment of microbial participation in formation of jarosite is an elementary step in geomicrobiological and astrobiological research. Isolated by us Rhodotorula sp. is an unicellular pigmented yeast. Fungi from the genus Rhodotorula F.C. Harrison belong to Sporidiobolalas part of phylum Basidiomycota. They are common environmental inhabitants. Some species, known from Rio Tinto, can live in extreme acidic soils at pH of about 2 (Lopez-Archila et al, 2004). For the first time, authors isolated strain Rhodotorula sp. from surface precipitates in Ł ęknica region (Muskau Arch). This ochreous precipitate contains jarosite. The yeast might be an important factor in indirect

    A comprehensive monitoring campaign to assess aldehydes and BTEX concentrations was performed during 12 months, in the Tijuca district (Rio de Janeiro), an area with commercial activities and a high flux of vehicles. The mean concentrations of formaldehyde and acetaldehyde were 151 and 30 ppb, respectively. The high formaldehyde/acetaldehyde ratio was attributed to extensive use of compressed natural gas (CNG). The number of CNG vehicles in the metropolitan Region of Rio de Janeiro increased from 23000 in January 2001 to 161000 in January 2005. Monitoring data show that, for the same period, methane and formaldehyde concentrations increased while NO(x) and CO levels diminished. Mean concentrations for benzene, toluene, ethylbenzene, m,p-xylene and o-xylene, were 1.1, 4.8, 3.6, 10.4 and 3.0 micro gm(-3), respectively. Benzene and toluene concentrations were lower than the values determined in 1996, for the same location. The levels of ethylbenzene and xylenes determined in this work are similar to values obtained in 1996. This fact may be explained as a consequence of changes in the gasoline composition.

    The Rio Claro and Piracununga formations cover extensive areas of the Paulista Peripheral Depression, dominantly in the region of Rio Claro and Piracununga cities. These units lie over the Corumbatai and Piramboia formations, exhibiting discordant contacts. The Rio Claro and Piracununga formations are composed of fine to medium sand facies, showing local cross-stratifications and parallel beddings with thin interbeddings of mud and gravel. These sands were dated by the Thermoluminescence Method, which indicated they were from the Pleistocene age. The oldest age (745,000 years BP) was found in deposits of the Rio Claro Formation; the other ages varied from 400,000 years BP to 145,000 years BP, for both formations. The youngest age (15,000 years BP - close to Pleistocene/ Holocene limit) was found in colluvial deposits, which rest on the Piracununga Formation. (author)

    Full Text Available This paper is supported by analysis and reflections on a concept of differentiated and essentially relational tourism which takes into account the complexity, diversity and contingencies associated with the local dynamics in the area of the Morro da Conceição, in the city of Rio de Janeiro, Brazil. The theoretical approach was based on the proposals of two authors: Symbolic Site of Belonging and Located Tourism of Hassan Zaoual and Geographic Area of Milton Santos. The empirical approach was developed in the light of the experiences of the Project Palacios do Rio, through participatory observations, interviews and secondary sources review. Elements and dynamics of Morro da Conceição were presented highlighting the historical context, heritage and daily life of residents and visitors of the site, and also conditions that enable the site for embracing Located Tourism. In conclusion we emphasize the importance of addressing human and social relations in tourism. Also, that the current dominant tourism industry, supported by superficial exchange and discrepant profit needs to give way to a kind of tourism that strengthens human and social values such as authenticity, solidarity, trust, empathy, curiosity and time for human relationship.

    The geomorphological study by means of remote sensing imagery of the Rio Pastaza Megafan (Ecuador and northern Peru) reveals the traces of numerous avulsions. One hundred and eight avulsion sites have been defined. The location of these sites, the available radiocarbon ages as well as historical maps of the seventeenth century, enable us to propose an evolution history of the migration and avulsions of the Rio Pastaza since the Last Glacial Maximum. The first avulsions of the Río Pastaza occurred after the LGM in a zone close to and roughly parallel to the sudandean front, where the developed avulsion gave a distributive pattern to the ancient stream of the Río Pastaza in an area located between the modern Río Morona and Pastaza, where they caused the Rio Pastaza to develop a fan-like distributary pattern. This is interpreted as a response to thrust-related forelimb tilt, progressively shifting eastward the Rio Pastaza and the apex of the megafan. This sequence of events ended with the Great Diversion of the Rio Pastaza towards the modern Rios Corrientes and Tigre. Avulsions occurred in the Tigre-Corrientes Area between 9200 and 8,500 years Cal BP. Afterwards, the Río Pastaza was diverted to its present-day north-south course. This last significant avulsion occurred before AD 1691. In the area located between the modern Río Morona and Pastaza, avulsion frequency—probably overestimated—ranges between 100 and 200 years. In the Ríos Tigre and Corrientes area, avulsion frequency—probably underestimated—ranges from 300 to 400 years. Regional tectonics is likely to have triggered most of the avulsions in the Morona Pastaza area but its influence is restricted to this area. The factors controlling the avulsions in the Tigre-Corrientes area are less clear because the frequently described "hydrologic"-driven avulsion as observed in areas characterized by contrasted hydrologic cycles are inconsistent with the characteristics of the hydrologic cycles of the Rio

    A number of investigations have shown that photoreduction of Fe(III) causes midday accumulations of dissolved Fe(II) in rivers and lakes, leading to large diel (24-h) fluctuations in the concentration and speciation of total dissolved iron. Less well appreciated is the importance of photoreduction in providing chemical energy for bacteria to thrive in low pH waters. Diel variations in water chemistry from the highly acidic (pH 2.3 to 3.1) Ri??o Tinto, Ri??o Odiel, and Ri??o Agrio of southwestern Spain (Iberian Pyrite Belt) resulted in daytime increases in Fe(II) concentration of 15 to 66????M at four diel sampling locations. Dissolved Fe(II) concentrations increased with solar radiation, and one of the stream sites showed an antithetic relationship between dissolved Fe(II) and Fe(III) concentrations; both results are consistent with photoreduction. The diel data were used to estimate rates of microbially catalyzed Fe(II) oxidation (1 to 3??nmol L- 1 s- 1) and maximum rates of Fe(III) photoreduction (1.7 to 4.3??nmol L- 1 s- 1). Bioenergetic calculations indicate that the latter rates are sufficient to build up a population of Fe-oxidizing bacteria to the levels observed in the Ri??o Tinto in about 30??days. We conclude that photoreduction plays an important role in the bioenergetics of the bacterial communities of these acidic rivers, which have previously been shown to be dominated by autotrophic Fe(II)-oxidizers such as Acidithiobacillus ferrooxidans and Leptospirillum ferrooxidans. Given the possibility of the previous existence of acidic, Fe(III)-rich water on Mars, photoreduction may be an important process on other planets, a fact that could have implications to astrobiological research. ?? 2008 Elsevier B.V.

Development at any cost can bring irreversible consequences for the ecosystems, the landscapes, the biosphere and its biological diversity. With the growing demand for natural resources the periodic diagnosis of the use of the soil becomes a fundamental aspect for the understanding of the patterns of organization of space, which are rarely permanent, in function of the high dynamics of anthropic activities . In this context, the derived information of orbital sensor, to gether with the geoprocessamento techniques, have been an efficient tool the characterization of elements of the landscape and in identification studies and maping of the natural resources. This work objectifies, then, the characterization and the environmental diagnosis of five microbasins of the Northwest area of the State of Big Rio of the South. The use of GIS was essential for obtaining the information related to the structural elements of the landscape as: hipsometria, clinografia, hidrografia, uses of the soil, risk areas and areas of permanent preservation. Agriculture represents the main occupation of the soil in the area, being necessary to promote the control and the accompaniment of the use of natural resources, mainly in the areas of permanent preservation, facilitating the execution of the environmental legislation. The available cartographic base for the making of precise thematic letters is limitante. This problem is not just local, the shortage of cartographic information is general Brazil as a whole.

    Full Text Available This paper deals with suicide in rural areas of Rio Grande do Sul, Brazil, considering the relation of this phenomenon with the advance of the capitalism in the countryside. This change has been creating new living and working styles and, besides, processes which lead to illness. Among these processes, suicide becomes a reality as a process of self-destruction and self-exclusion. These are sociopathologies of the development which are created in demonstrations of mental illness, depression and suicides, driven by a model of development imposed in the rural area through the economic incentive and, also, through all the economic speech carrying a project of hope. It is about the social and economic systems acting as generators of precariousness, human, familiar and psycho-philosophical costs, desocialization processes, self-generated alienation and self-cleaving, showing that it is increasingly necessary to think about the relation between the social and the individual in life and death processes

    Full Text Available Spatial patterns of shallow landslide initiation reflect both spatial patterns of heavy rainfall and areas susceptible to mass movements. We determine the areas most susceptible to shallow landslide occurrence through the calculation of critical soil cohesion and spatial patterns of rainfall derived from TRMM (Tropical Rainfall Measuring Mission data for Paraty County, State of Rio de Janeiro, Brazil. Our methodology involved: (a creating the digital elevation model (DEM and deriving attributes such as slope and contributing area; (b incorporating spatial patterns of rainfall derived from TRMM into the shallow slope stability model SHALSTAB; and (c quantitative assessment of the correspondence of mapped landslide scars to areas predicted to be most prone to shallow landsliding. We found that around 70% of the landslide scars occurred in less than 10% of the study area identified as potentially unstable. The greatest concentration of landslides occurred in areas where the root strength of vegetation is an important contribution to slope stability in regions of orographically-enhanced rainfall on the coastal topographic flank. This approach helps quantify landslide hazards in areas with similar geomorphological characteristics, but different spatial patterns of rainfall.

    The Rio Grande Gorge is a 115 km long river canyon located in Southern Colorado (15 km) and Northern New Mexico (100 km). The majority of the canyon is under the administration of the Bureau of Land Management {BLM), and 77 km of the canyon south of the Colorado/New Mexico border are designated Wild River under the National Wild and Scenic Rivers Act of 1968. Visits I have made to the Rio Grande Gorge over the past 15 .years disclosed some raptor utilization. As the Snake River Birds of Prey Natural Area gained publicity, its similarity to the Rio Grande Gorge became obvious, and I was intrigued by the possibility of a high raptor nesting density in the Gorge. A survey in 1979 of 20 km of the northern end of the canyon revealed a moderately high density of red-tailed hawks and prairie falcons. With the encouragement of that partial survey, and a need to assess the impact of river-running on nesting birds of prey, I made a more comprehensive survey in 1980. The results of my surveys, along with those of a 1978 helicopter survey by the BLM, are presented in this report, as well as general characterization of the area, winter use by raptors, and an assessment of factors influencing the raptor population.

    Highlights: • The system presented acquires and process images from any CameraLink compliant camera. • The frame grabber implanted with FlexRIO technology have image time stamping and preprocessing capabilities. • The system is integrated into EPICS using areaDetector for a flexible configuration of image the acquisition and processing chain. • Is fully compatible with the architecture of the ITER Fast Controllers. - Abstract: Image processing systems are commonly used in current physics experiments, such as nuclear fusion experiments. These experiments usually require multiple cameras with different resolutions, framerates and, frequently, different software drivers. The integration of heterogeneous types of cameras without a unified hardware and software interface increases the complexity of the acquisition system. This paper presents the implementation of a distributed image acquisition and processing system for CameraLink cameras. This system implements a camera frame grabber using Field Programmable Gate Arrays (FPGAs), a reconfigurable hardware platform that allows for image acquisition and real-time preprocessing. The frame grabber is integrated into Experimental Physics and Industrial Control System (EPICS) using the areaDetector EPICS software module, which offers a common interface shared among tens of cameras to configure the image acquisition and process these images in a distributed control system. The use of areaDetector also allows the image processing to be parallelized and concatenated using: multiple computers; areaDetector plugins; and the areaDetector standard type for data, NDArrays. The architecture developed is fully compatible with ITER Fast Controllers and the entire system has been validated using a camera hardware simulator that stream videos from fusion experiment databases.

    In the scientific literature, sporotrichosis has traditionally been associated with agricultural work, since the causative agent is found naturally in the soil. However, cases have been reported recently in an urban area, related to zoonotic transmission. The current study aimed to contribute to knowledge on sporotrichosis in an urban area through an exploratory analysis of its socio-spatial distribution in Rio de Janeiro, Brazil, from 1997 to 2007, identifying the areas with the heaviest transmission. The database from the Health Surveillance Service at the Evandro Chagas Institute for Clinical Research, Oswaldo Cruz Foundation, was used to estimate incidence rates and spatial distribution. During the study period, 1,848 cases of sporotrichosis were reported, predominantly in adult women not currently in the labor market. The leading source of infection was wounds caused by domestic cats, which contributed to the spread of sporotrichosis in this urban area. Georeferencing of 1,681 cases showed a transmission belt along the border between the city of Rio de Janeiro and the adjacent municipalities in the Greater Metropolitan Area.

    Full Text Available The 1992 Rio Earth Summit was of paramount importance in the consolidation and international dissemination of environmental impact assessment, officially recognized as a tool for informed decision-making towards sustainable development (Principle 17, Rio Declaration and for protection of biodiversity (Article 14, Convention on Biological Diversity. A significant development afterwards was the strengthening of strategic environmental assessment in the design of policies, plans and programs. Both forms of impact assessment can establish the necessary connections between one goal of the Rio+20 Conference - reaching an agreement on the transition to a green economy - and the underpinning decision making processes. Although the Rio+20 Summit has faced challenges to acknowledge its potential, impact assessment should be strengthened in support of both government and business decisions.La Cumbre de la Tierra de 1992 fue de la más grande importancia en la consolidación y diseminación de la evaluación de impacto ambiental, oficialmente reconocida como una herramienta para la toma de decisiones informada hacia el desarrollo sostenible (Principio 17, Declaración de Rio y para la protección de la biodiversidad (Artículo 14, Convención de la Diversidad Biológica. Un avanzo posterior importante fue el fortalecimiento de la evaluación ambiental estratégica en la preparación de políticas, planos y programas. Ambas formas de evaluación de impacto son capaces de establecer los necesarios vínculos entre un objetivo declarado de la Conferencia Rio+2- - llegar a un acuerdo sobre la transición para una economía verde - y los procesos decisorios subyacentes. Aunque la Cumbre Rio+20 tenga encontrado dificultades en reconocer su potencial, la evaluación de impactos debería ser fortalecida en soporte de decisiones gubernamentales y privadas.A Cúpula da Terra de 1992, no Rio de Janeiro, teve a maior importância na consolidação e dissemina

    Full Text Available Ichthyoplankton samples and hydrological data were obtained in an inshore area, between the mouths of the Rivers Guadalquivir and Guadiana (Gulf of Cádiz, SW Spain during monthly surveys carried out from March 2002 to March 2003. Horizontal and temporal distributions of wedge sole (Dicologlossa cuneata egg and larval abundances were analysed during this annual cycle in relation to environmental parameters. This area proved to be an important spawning and nursery ground for the species, which showed a winter-spring reproductive strategy with a long reproductive period lasting from autumn until early summer. Spawning areas were located in the shallowest waters (above 30 m depth between the mouths of the Rives Guadiana and Tinto-Odiel, and to a lesser extent in the coastal zone between the mouths of the Rivers Tinto-Odiel and Guadalquivir. The spawning habitat was mainly determined by the distribution of the adults, the bathymetry and the temperature, and a preference for shallow and colder waters was observed. The inshore zone between the mouths of the Rivers Tinto-Odiel and Guadalquivir is the main nursery ground, with the greatest larval concentration and productivity in the area, due to the influence of the River Guadalquivir. The presence of recruits in this area may be linked to these favourable conditions for larval growth and survival.

    Full Text Available Um novo inquérito para oncocercose, realizado em 1984, entre índios Yanomami da parte média dos rios Mucajaí e Catrimâni (Território de Roraima, mostrou que, decorridos vários anos das primeiras investigações - uma década no caso do rio Mucajaí - os índices de prevalência, nesses dois locais da periferia do foco brasileiro, não haviam sofrido alteração significativa. Levando-se em conta apenas os residentes nas aldeias ou malocas abrangidas pelo inquérito, a prevalência atingiu 3,1% nos índios do rio Mucajaí, enquanto ficou em zero nos do rio Catrimâni. Dada a presença contínua, nas referidas aldeias, de índios visitantes, altamente infectados, oriundos da parte central e mais elevada do território indígena - onde cerca de 90% doa adultos têm oncocercose - seria de esperar o achado de valores bem maiores (acima pelo menos daqueles encontrados anteriormente, caso um vetor apropiado estivesse presente na região.

    An ecosystem is rarely static. A natural system composed of plants, animals, and microorganisms interacting with an area's physical factors, an ecosystem is always fluctuating and evolving. But sometimes, often at the hands of humans, ecosystems change too much. Such is the case with many of the ecosystems of the Middle Rio Grande Basin of New Mexico.

  8. Variable exchange between a stream and an aquifer in the Rio Grande Project Area

    2016-12-01

    Both surface water and groundwater in the Rio Grande Project area in southern New Mexico and Far West Texas have been stressed by natural conditions such as droughts and human activities, including urban development and agricultural irrigation. In some area pumping stress in the aquifer becomes so great that it depletes the river flow especially during the irrigation season, typically from March through October. Therefore understanding such relationship between surface water and groundwater becomes more important in regional water resources planning and management. In this area, stream flows are highly regulated by the upstream reservoirs during the irrigation season and greatly influenced by return flows during non-irrigation season. During a drought additional groundwater pumping to supplement surface water shortage further complicates the surface water and groundwater interaction. In this paper the authors will use observation data and results of numerical models (MODFLOW) to characterize and quantify hydrological exchange fluxes between groundwater in the aquifers and surface water as well as impacts of groundwater pumping. The interaction shows a very interesting seasonal variation (irrigation vs. non-irrigation) as well as impact of a drought. Groundwater has been pumped for both municipal supplies and agricultural irrigation, which has imposed stresses toward both stream flows and aquifer storage. The results clearly show that historic groundwater pumping has caused some reaches of the river change from gaining stream to losing stream. Beyond the exchange between surface water and groundwater in the shallow aquifer, groundwater pumping in a deep aquifer could also enhance the exchanges between different aquifers through leaky confining layers. In the earlier history of pumping, pumping from the shallow aquifer is compensated by simple depletion of surface water, while deep aquifer tends to use the aquifer storage. With continued pumping, the cumulative

    Full Text Available Este artigo trata da distribuição dos investimentos em equipamentos de saneamento básico na Região Metropolitana do Rio de Janeiro no período 1975-91. Distribuímos as inversões realizadas pela concessionária estadual, a Cedae, em uma base espacial produzida especialmente para a realização da presente pesquisa. Esta base foi construída utilizando como indicadores sociais informações do Censo demográfico de 1980, único realizado no decorrer do período estudado. As transformações recentes observadas são explicadas a partir das conjunturas sócio-espaciais e políticas da metrópole e do país, assim como da própria forma de organização dos serviços. O trabalho acrescenta importantes argumentos aos debates sobre a reestruturação dos espaços metropolitanos e as políticas públicas urbanas. A distribuição espacial e social dos investimentos observada no período diferiu do padrão vigente até então, mas, embora tenha ocorrido uma substancial democratização na alocação dos recursos públicos, o padrão não foi subvertido.This article deals with the distribution of financial resources allocated to the basic sanitary systems in the Rio de Janeiro metropolitan area during the 1975-1991 period. The study analyzes the investments allocated by the local utility company, known as Cedae, using a spatial model produced especially for this research. The model was produced using information from the national demographic census of 1980, the only one developed within the study period. The recent changes as observed are explained on the basis of their relationship to the spatial and political contexts in the metropolis and the country, as well as from the organization of the services themselves. The paper adds important arguments to the discussion over the restructuring of metropolitan areas and urban public policies.

    Angiostrongylus cantonensis is considered the main etiological agent of eosinophilic meningitis in humans. At present, this zoonosis is considered an emerging disease mainly in the Americas. The aim of this study was to determine the prevalence of Achatina fulica infected by Angiostrongylus cantonensis in restinga areas along beaches in the west zone of Rio de Janeiro city, Brazil. The study areas included the following beaches: Barra da Tijuca, Recreio dos Bandeirantes, Reserva, Prainha and Grumari. Ninety specimens of Achatina fulica were collected. Positive molluscs were found only in Barra da Tijuca. Infection prevalence was 5.5%. The presence of this parasite in the beachfront areas, in the west zone of Rio de Janeiro city demonstrates the potential risk of infection for visitors and the expansion of this helminth in the State of Rio de Janeiro.

    Full Text Available The lethality of malaria in the extra-Amazonian region is more than 70 times higher than in Amazonia itself. Recently, several studies have shown that autochthonous malaria is not a rare event in the Brazilian southeastern states in the Atlantic Forest biome. Information about autochthonous malaria in the state of Rio de Janeiro (RJ is scarce. This study aims to assess malaria cases reported to the Health Surveillance System of the State of Rio de Janeiro between 2000-2010. An average of 90 cases per year had parasitological malaria confirmation by thick smear. The number of malaria notifications due to Plasmodium falciparum increased over time. Imported cases reported during the period studied were spread among 51% of the municipalities (counties of the state. Only 35 cases (4.3% were autochthonous, which represents an average of 3.8 new cases per year. Eleven municipalities reported autochthonous cases; within these, six could be characterised as areas of residual or new foci of malaria from the Atlantic Forest system. The other 28 municipalities could become receptive for transmission reintroduction. Cases occurred during all periods of the year, but 62.9% of cases were in the first semester of each year. Assessing vulnerability and receptivity conditions and vector ecology is imperative to establish the real risk of malaria reintroduction in RJ.

    Full Text Available Experimental releases of female Aedes (Stegomyia aegypti and Aedes (Stegomyia albopictus were performed in August and September 1999, in an urban area of Nova Iguaçu, State of Rio de Janeiro, Brazil, to estimate their flight range in a circular area of 1,600 m where 1,472 ovitraps were set. Releases of 3,055 Ae. aegypti and 2,225 Ae. albopictus females, fed with rubidium (Rb-marked blood and surgically prevented from subsequent blood-feeding, were separated by 11 days. Rb was detected in ovitrap-collected eggs by atomic emission spectrophotometry. Rb-marked eggs of both species were detected up to 800 m from the release point. Eggs of Ae. albopictus were more numerous and more heterogeneously distributed in the area than those of Ae. aegypti. Eggs positively marked for Rb were found at all borders of the study area, suggesting that egg laying also occurred beyond these limits. Results from this study suggest that females can fly at least 800 m in 6 days and, if infected, potentially spread virus rapidly.

    The determination of multielemental concentrations in physiological fluids is of considerable interest in clinical chemistry. Since it has been established this levels in human serum can be utilized as indicators for several pathological conditions. The multielement composition determination in human serum is important for the investigation of their role in human physiology and metabolism. From this research, more detailed studies on the health of individuals living in the metropolitan region of the state of Rio de Janeiro can be realized in order to improve the quality of life of these individuals. We studied three hundred and sixty healthy volunteers (162 males and 198 females) aged 18 to 60 years old. All the serum samples had been collected of people who live in the urban area of Rio de Janeiro City/Brazil. The measurements were performed at the X-Ray Fluorescence Beamline at the Brazilian National Synchrotron Light Laboratory (LNLS), in Campinas, Sao Paulo using a monochromatic beam with maximum energy of 20 keV for the excitation and an Ultra-LEGe detector with resolution of 148 eV at 5.9 keV.

All the serum samples had been collected of people who live in the urban area of Rio de Janeiro City/Brazil. The measurements were performed at the X-Ray Fluorescence Beamline at the Brazilian National Synchrotron Light Laboratory (LNLS), in Campinas, Sao Paulo using a monochromatic beam with maximum energy of 20 keV for the excitation and an Ultra-LEGe detector with resolution of 148 eV at 5.9 keV. Standards solutions with Vanadium and Galium (Internal standards) were prepared for the calibration system. It was possible to determine the elemental concentrations of the following eleven elements: Na, P, S, Cl, K, Ca, Fe, Cu, Zn, Br and Rb. (author)

    Full Text Available Inventários de fauna acessam diretamente a diversidade de uma localidade, em um determinado espaço e tempo. Os dados primários gerados pelos inventários compõem uma das ferramentas mais importantes na tomada de decisões a respeito do manejo de áreas naturais. Entretanto, vários problemas têm sido observados em diversos níveis relacionados aos inventários de fauna no Brasil e vão desde a formação de recursos humanos até a ausência de padronização, de desenho experimental e de seleção de métodos inadequados. São apresentados estudos de caso com mamíferos, répteis, anfíbios e peixes, nos quais são discutidos problemas como variabilidade temporal e métodos para detecção de fauna terrestre, sugerindo que tanto os inventários quanto os programas de monitoramento devam se estender por prazos maiores e que os inventários devem incluir diferentes metodologias para que os seus objetivos sejam plenamente alcançados.Inventories of fauna directly access the diversity of a locality in a certain period of time. The primary data generated by these inventories comprise one of the most important steps in decisions making regarding the management of natural areas. However, several problems have been observed at different levels related to inventories of fauna in Brazil, and range from the training of humans to the lack of standardization of experimental design and selection of inappropriate methods. We present case studies of mammals, reptiles, amphibians and fishes, where they discussed issues such temporal variability and methods for detection of terrestrial fauna, suggesting that both inventories and monitoring programs should be extended for longer terms and that inventories should include different methodologies to ensure that their goals are fully achieved.

    In 1966 an intensive exploration programme was conducted by Rio Tinto South Africa Ltd, involving airborne and ground radiometric surveys, percussion and diamond drilling, and pilot-plant tests. This investigation established the presence of a large deposit of low-grade uranium that could be mined on a large scale by open-pitting. Soon after production started in June 1974, it was realized that the original presentation of the ore reserves did not give a true reflection of the orebody. A comparison between the estimates and the ore mined from reserve blocks over the period 1975 to 1977 showed that the reserve grades were over-optimistic. In 1977 Rio Tinto Zinc Consultants were commissioned to re-evaluate the ore reserves from exploration diamond-drill data with the help of The Centre de Geostatistique at Fontainebleau, France. A new global reserve using disjunctive kriging techniques was developed, and is now the long-term reserve used for planning purposes at the Roessing Mine. For short-term planning, ore-reserve data are replaced by information from an intermediate drilling programme and blast-hole assays if these are available. A computerized short-term planning system has been established that reconciles the ore mined against the reserve blocks, as well as a system by which composited blast-hole assays are analysed for grade-control purposes. Owing to the complexity of the orebody, additional monitoring is achieved by the scanning of each truckload of ore with a group of scintillation crystal heads that evaluate the material mined

    Full Text Available The United Nations Conference on Environment and Development (UNCED took place in the city of Rio de Janeiro in 1992 and put the concept of Sustainable Development definitively on policy agendas at all levels from global to local. Twenty years later, even though important progress has been made in several areas, the world still struggles to implement the decisions following up the UNCED and to steer humanity towards a more sustainable path. The UN has set two broad themes for the Earth Summit in 2012, or Rio+20: institutional framework for sustainable development (IFSD and green economy in the context of sustainable development and poverty eradication. This article makes an overall analysis of the discussions generated by Rio+20. The article starts with a short overview of the debates on sustainable development since the UNCED, until the recent debates on green economy and institutional frameworks for sustainable development. It then highlights some lessons from the discussions catalyzed by Rio+20 analysing why and how progress has been achieved in certain areas and what the obstacles are to move the agenda of green economy and good environmental governance forward to achieve a more sustainable development. It concludes that, besides the tremendous obstacles to implement the agenda on green economy and IFSD, these themes brought about in Rio+20 are still lacking conceptually in the discussions on important topics such as equity and need to changes in values, as well as the debates on governance beyond the international level.

    Full Text Available Abstract Background The Rio Grande River is the natural boundary between U.S. and Mexico from El Paso, TX to Brownsville, TX. and is one of the major water resources of the area. Agriculture, farming, maquiladora industry, domestic activities, as well as differences in disposal regulations and enforcement increase the contamination potential of water supplies along the border region. Therefore, continuous and accurate assessment of the quality of water supplies is of paramount importance. The objectives of this study were to monitor water quality of the Rio Grande and to determine if any correlations exist between fecal coliforms, E. coli, chemical toxicity as determined by Botsford's assay, H. pylori presence, and environmental parameters. Seven sites along a 112-Km segment of the Rio Grande from Sunland Park, NM to Fort Hancock, TX were sampled on a monthly basis between January 2000 and December 2002. Results The results showed great variability in the number of fecal coliforms, and E. coli on a month-to-month basis. Fecal coliforms ranged between 0–106 CFU/100 ml while E. coli ranged between 6 to > 2419 MPN. H. pylori showed positive detection for all the sites at different times. Toxicity ranged between 0 to 94% of inhibition capacity (IC. Since values above 50% are considered to be toxic, most of the sites displayed significant chemical toxicity at different times of the year. No significant correlations were observed between microbial indicators and chemical toxicity. Conclusion The results of the present study indicate that the 112-Km segment of the Rio Grande river from Sunland Park, NM to Fort Hancock, TX exceeds the standards for contact recreation water on a continuous basis. In addition, the presence of chemical toxicity in most sites along the 112-Km segment indicates that water quality is an area of concern for the bi-national region. The presence of H. pylori adds to the potential health hazards of the Rio Grande. Since no

O Sistema Único de Saúde, cujas deretrizes preconizam a atenção universal e eqüânime, determina a relevância desta temática dentro do campo da avaliação dos serviços de saúde. Assim, foram estudados dois ambulatórios de pediatria de um hospital universitário, um geral e outro de uma subespecialiadade (pneumologia, comparando os usuários quanto ao acesso. MÉTODO: Foram aplicados 221 questionários entre clientes de ambos os ambulatórios de pediatria com o objetivo de se estudar e comparar variáveis socioeconômicas, procedência, acesso aos referidos ambulatórios e outros serviços de saúde. RESULTADOS: Evidenciou-se grande dificuldade de locomoção dos pacientes, a maioria dos quais são encaminhados por serviços de saúde locais. Dos pacientes atendidos 40% não receberam nenhum atendimento anteriormente à sua chegada ao hospital, fato que decorre principalmente de seu baixo nível socioeconômico, que os torna dependentes exclusivamente dos serviços públicos de saúde. A comparação entre os dois ambulatórios mostra que os pacientes do ambulatório de especialidade têm melhor nível socioeconômico e são menos dependentes dos serviços públicos, configurando desta forma uma situação de ineqüidade. CONCLUSÕES: É apontado o melhor nível socioeconômico dos usuários da especialidade bem como questões organizacionais do próprio serviço como os responsáveis pela iniqüidade verificada.

    Sedimentation of Rio La Venta as it enters the Netzahualcoyotl Reservoir in Chiapas, Mexico, threatens a unique part of the aquatic ecosystem. Rio La Venta enters the reservoir via a narrow canyon about 16 km long with spectacular, near-vertical limestone bluffs up to 320 m high and inhabited by the flora and fauna of a pristine tropical forest. Karst terrain underlies most of the Rio La Venta basin in the vicinity of the reservoir, while deeply weathered granitic terrain underlies the Rio Negro basin, and the headwaters of the Rio La Venta to the south. The Rio Negro joins Rio La Venta 3 km downstream of the upper limit of the reservoir and delivers the bulk of the total clastic sediment (mostly sand and finer material). The canyon and much of the contributing basin lie within the Reserva de la Biosfera, Selva El Ocote, administered by the Comision Nacional de Areas Naturales Protegidas, part of the Secretaria de Medioambiente y Recursos Naturales. The Klamath National Forest Forest has cooperated with its Mexican counterparts since 1993 in natural resource management, neo-tropical bird inventories, wildfire management, and more recently in watershed analyses. Rates of sedimentation are estimated from bathymetric surveys conducted in March, 2002. A longitudinal profile down the inundated canyon during a high reservoir level shows an inflection from a slope of 0.0017 to one of 0.0075 at 7.2 km downstream of the mouth of Rio Negro. The bed elevation at this point corresponds to the lowest reservoir level, suggesting that the gentler sloping bed upstream is formed by fluvial processes during drawdown and that downstream by pluvial processes. Using accounts that boats could access Rio Negro during low water levels in 1984, we estimate an annual sedimentation rate of roughly 3 million cubic meters per year. This suggests that boats might no longer be able to access the most spectacular section of canyon upstream of Rio Negro within a decade, depending on how the

    The Tinto and Odiel rivers in southwest Spain drain the world's largest sulfide mineral formation: the Iberian Pyrite Belt which has been worked since 2,500 BC. The Tinto and Odiel estuarine zones include both an extensive area of salt marsh and an intensively industrialized urban area. As a consequence of pyrite oxidation, the Tinto and Odiel rivers are strongly acidic (pH major and trace elements were determined in the acid mine drainage affected estuary of the Ría de Huelva. During estuarine mixing, ore-derived metal concentrations exhibit excellent correlations with pH as the main controlling parameter. As pH increases, concentrations of dissolved ore-associated elements are attenuated, and this process is enhanced during the summer months. The decrease in Fe and Al concentrations ranged from 80 to 100 % as these elements are converted from dissolved to sediment-associated forms in the estuary. Coprecipitation/adsorption processes also removed between 60 and 90 % of the originally dissolved Co, Cu, Mn, Pb, Zn, and Th; however, Cd and Ni exhibited a greater propensity to remain in solution, with an average removal of approximately 60 %. On the other hand, As and U exhibited a different behavior; it is likely that these elements remain in dissolved forms because of the formation of U carbonates and soluble As species. Concentrations of As remain at elevated levels in the outer estuary (average = 48 μg L(-1)) which exceeds concentrations present in the Tinto River. Nevertheless, the estuary has recently witnessed improvements in water quality, as compared to results of several previous studies reported in the 1990s.

    Full Text Available Abstract This paper deals with suicide in rural areas of Rio Grande do Sul, Brazil, considering the relation of this phenomenon with the advance of the capitalism in the countryside. This change has been creating new living and working styles and, besides, processes which lead to illness. Among these processes, suicide becomes a reality as a process of self-destruction and self-exclusion. These are sociopathologies of the development which are cre- ated in demonstrations of mental illness, depression and suicides, driven by a model of development imposed in the rural area through the economic incentive and, also, through all the economic speech carrying a project of hope. It is about the social and economic systems act- ing as generators of precariousness, human, familiar and psycho-philosophical costs, desocialization processes, self-generated alienation and self-cleaving, showing that it is increasingly necessary to think about the relation between the social and the individual in life and death processes. Resumo Este artigo trata da questão do suicídio no meio ru- ral no Rio Grande do Sul, Brasil, a partir da articulação deste fenômeno com o avanço capitalista no meio rural.

    In Costa Rica there are no studies that have documented the concentrations of heavy metals in river sediments, caused by point sources of pollutants, such as the deposits sites of solid waste. The potential source of heavy metals concentrations in the study area, is an active landfill, known as Relleno Sanitario de Rio Azul, which is located southeast of the city of San Jose, in Distrito de Rio Azul de La Union. The site where the landfill Rio Azul is located is composed by a sequence of volcanic materials, which could have been affected by local faulting. This fact would mean a serious threat of contamination of groundwater in the region, geological faults are therefore a highly permeable, able to get in touch the fill pollutants with some aquifer. The mass of metal deposited on the site, from 1978 to date, has been estimated between 70000-100000 tm, which it becomes environmental concern in a first order. The results of X-ray fluorescence show the presence of elements such as vanadium, chromium, magnesium, copper, zinc, rubidium, strontium, potassium, calcium, iron, titanium and yttrium, which show a trend towards more high Concentrates in the fine fraction (d [es

    Magnetotelluric (MT) and transient electromagnetic (TEM) data were acquired by students from the Summer of Applied Geophysical Experience (SAGE) to construct structural models in and around the Caja del Rio Plateau, New Mexico. The Caja del Rio is located on the La Bajada-Jemez constriction that separates the Española and Santa Domingo basins in the Rio Grande Rift. The Rio Grande Rift, the result of tectonic extensional forces, extends approximately north-south across northern New Mexico. MT data collected in 2016 were merged with that from previous years to make up an 11 km north line and a 16 km south line extending from the west side of the Caja Del Rio to the east off the plateau in the Old Buckman Road area. The resistivity distributions revealed in one-dimensional (1-D) and two-dimensional (2-D) inverse models show some robust features. Models of the north are interpreted as a top resistive layer (convention) point in the northwest direction towards the conductive Valles Caldera. The MT models are consistent with geologic interpretations of the stratigraphic units. In addition, models disclose an additional conductive layer below the basement that we interpret as the mid-crustal conductor. Transient electromagnetic (TEM) data were collected in seven locations atop the Caja del Rio plateau in an attempt to identify the basal contact of the Cerros del Rio volcanic field, which, in turn, allow for the thickness of these basaltic and andesitic deposits to be mapped across the plateau. One-dimensional inverse models produced from the TEM data were aligned and interpreted geologically. A resistive ( 1000 ohm-m) unit, interpreted to represent the Cerros del Rio volcanics, thickens from 70m to 175m from southeast to northwest. The volcanics are overlain by a thin conductor, interpreted as weathered material. The resistive body is underlain by a thicker conductor, interpreted as sedimentary rocks of the Tertiary-aged Santa Fe Group.

    Directory of Open Access Journals (Sweden)

    Leonardo F. S. Ingenito

    Full Text Available Rineloricaria langei and R. maacki, new species, are described from upper and middle regions of the rio Iguaçu basin, a left bank tributary of the rio Paraná basin, southern Brazil. Rineloricaria langei has narrow body and is similar to R. quadrensis, which is found in coastal rivers of Rio Grande do Sul State and is distinguishable by several morphometric characters. Rineloricaria maacki is distinguishable from all other congeners by the shape and extension of the naked area of the ventral region of pectoral girdle and other morphological characters. The presence of a naked region on the abdominal surface is shared with other species from the rio Paraná and rio Uruguay basins and coastal drainages from southeastern and southern Brazil. This may indicate a close phylogenetic relationship among these species. Similarities between the two new species and species from the aforementioned drainages also suggest close biogeographic relationship between the Paraná basin and other Brazilian coastal Atlantic drainages throughout the rio Iguaçu basin.

    Few historical streamflow and water-quality data are available to characterize the segment of the Rio Grande/Rio Bravo del Norte (hereinafter Rio Grande) extending from near Presidio to near Langtry, Texas. The U.S. Geological Survey, in cooperation with the National Park Service and the Texas Commission on Environmental Quality, collected water-quality and streamflow data from the Rio Grande from near Presidio to near Langtry, Texas, to characterize the streamflow gain and loss and selected constituent concentrations in a 336.3-mile reach of the Rio Grande from near Presidio to near Langtry, Texas. Streamflow was measured at 38 sites and water-quality samples were collected at 20 sites along the Rio Grande in February, March, and June 2006. Streamflow gains and losses over the course of the stream were measured indirectly by computing the differences in measured streamflow between sites along the stream. Water-quality data were collected and analyzed for salinity, dissolved solids, major ions, nutrients, trace elements, and stable isotopes. Selected properties and constituents were compared to available Texas Commission on Environmental Quality general use protection criteria or screening levels. Summary statistics of selected water-quality data were computed for each of the five designated subreaches. Streamflow gain and loss and water-quality constituent concentration were compared for each subreach, rather than the entire segment because of the temporal variation in sample collection caused by controlled releases upstream. Subreach A was determined to be a losing reach, and subreaches B, C, D, and E were determined to be gaining reaches. Compared to concentrations measured in upstream subreaches, downstream subreaches exhibited evidence of dilution of selected constituent concentrations. Subreaches A and B had measured total dissolved solids, chloride, and sulfate exceeding the Texas Commission on Environmental Quality general use protection criteria

    Full Text Available Introduction Nine cases of visceral leishmaniasis occurred recently in Barra Mansa, State of Rio de Janeiro, with a high mortality rate. Methods We reviewed the medical records of the patients. Results Eight were male; 7 were adults. Patients who died progressed to death quickly and presented with aggravating factors: systemic steroid therapy before diagnosis, bleeding, severe liver involvement, infection, and/or refusal to receive transfusion. Conclusions We warn clinicians to be aware of the emergence of visceral leishmaniasis in new areas and to keep in mind the possibility of atypical clinical pictures and aggravating factors, so timely diagnosis can be made and prompt and adequate treatment can be initiated.

    Full Text Available Oxides containing aluminium and barium, optionally with chromium, are refractory with several possible industrial uses. A gel precursor of an oxide having the formula BaO.n(Al2xCr2yO3, where 1Oxidos contendo alumínio e bário, opcionalmente com crômio, são refratários com vários possíveis usos industriais. Foi preparado um gel precursor de um óxido de formula BaO.n(Al2xCr2yO3, com 1rio com uma solução de um sal de bário com solução de um sal de alumínio ou uma solução de um sal de alumínio e um sal de cromo III, formando então um gel que é queimado para se obter o óxido desejado. Filamentos podem ser estraídos duramente a formação do gel ou extrudados de um gel semi-rígido. Estudos de infravermelho com transformada de Fourier, difração de raios X e ressonância magnética nuclear com 27AL mostraram que o bário não é incorporado diretamente na estrutura do gel. Oxidos de alumínio e bário foram obtidos somente após liquefação de espécies de bário. Foi preparada uma mistura de pós adequada para queima para se obter um óxido de fórmula BaO.m[Al2x Cr2y O3] com 4,6rio, óxido de bário, carbonato de bário e mono-aluminato de bário, alumina e/ou alumina hidratada e óxido de cromo III, com quantidades relativas variando para se obter na queima valores desejados de m e de y. Corpos cerâmicos resistentes da fórmula BaO 6 Al2O3 (m=6 e y=0 foram preparados. Estudos de difração de raios X de óxidos de composições (n ou m=6 e y=0 sinterizados em alta temperatura mostraram que mono-aluminato de bário é uma fase intermediária de baixa temperatura. Cromo III reduz a temperatura necessária para formar um óxido de alumínio e bário. É feito um sumário de trabalhos anteriormente publicados.

    Full Text Available No planejamento de recursos em saúde é importante o conhecimento da área de abrangência de uma unidade. Os Diagramas de Voronoi constituem uma técnica para tal; são polígonos construídos de tal forma que as bordas de polígonos adjacentes encontram-se eqüidistantes de seus respectivos pontos geradores. Uma modificação nas áreas de abrangência assim definidas é sua ponderação (Diagramas de Voronoi ponderados, representando a capacidade da unidade de forma mais real. No presente trabalho foram utilizados, como pontos geradores, 21 hospitais gerais públicos no Rio de Janeiro, RJ. Inicialmente foram criados os Diagramas de Voronoi sem ponderação, e, a partir destes, os diagramas ponderados, empregando-se como variável de ponderação as estimativas de internação anual para cada unidade. Na divisão clássica, áreas de abrangência similares foram atribuídas a hospitais com características diferenciadas, problema esse contornado no método ponderado. O método é de simples implementação e visualização, utiliza dados de fácil acesso e independe de parâmetros arbitrários ou geopolíticos. Portanto, esses diagramas podem fornecer, a gerentes de saúde, uma visão mais realista para o planejamento da demanda de suas unidades.One of the most important pieces of information for health resources planning is the definition of catchment areas for health units. Voronoi Diagrams are a potential technique for this purpose. They are polygons with the property whereby adjacent polygons have their borders located within the same distance of the respective generator points. One possible adjustment to the catchment areas thus defined is the use of weighted Voronoi Diagrams, which result in an improved representation of a health unit's actual capacity. In this study, the 21 public general hospitals in the city of Rio de Janeiro, Brazil, were used as generator points for Voronoi Diagrams. Non-weighted Voronoi Diagrams were initially

Identifica-se a consolidação de dois territórios existenciais, que ora se aproximam, ora se afastam: o do saber técnico em saúde e o do saber popular em saúde. A partir da análise de algumas falas de ACS e de reflexões que dialogam com o referencial teórico da área, o texto discute alguns dos dilemas e impasses do acesso e da adesão na ótica desses Agentes, bem como as estratégias cotidianamente inventadas a partir dos encontros que se dão entre esses dois territórios. Identifica-se o lugar do Agente Comunitário de Saúde como agenciador de fronteiras, atuando em alguns momentos como um inventor ou potencializador de zonas de contato entre territórios e, em outros, como um representante de um dos territórios no outro.This article presents reflections originating from a series of meetings with community health workers over a period of ten years. It identifies the consolidation of two existential territories, which are sometimes closer and at other times more distant from each other, namely the territory of technical knowledge about health and the territory of popular knowledge about health. Starting with the analysis of some quotes from health workers and reflections which tally with the theoretical reference in the area, this paper discusses some of the dilemmas and deadlocks of access and affiliation from the perspective of some of these health workers, as well as the strategies devised on a day-to-day basis from the crossovers that take place between these two territories. It identifies the function of community health workers as frontier agents, at times acting as inventors or motivators of contact zones between the territories, and at other times acting as a representative by one territory inside the other.

    Full Text Available Sanitary sewage collection and treatment is a serious environmental problem in Brazilian cities, as well as the destination of solid waste resulting from this process, i.e. the sewage sludge, a substance rich in organic matter and nutrients, which is normally discarded in landfills. The aim of this study was to characterize the sewage sludge generated in four treatment stations in Rio de Janeiro State, Brazil and check if they meet the legal criteria of the National Environment Council (CONAMA, Resolution No. 375/2006. It also focused on analyzing the perspectives for its agricultural recycling based on the potential demand for main agricultural crops grown in Rio de Janeiro State. Samples from eight sewage sludge lots from four treatment stations located in the metropolitan area of Rio de Janeiro were analyzed. These stations receive and treat only domestic sewage by activated sludge system. For chemical and biological characterization of these lots, representative samples were collected and analyzed according to parameters of CONAMA Resolution No. 375/2006. In order to analyze the perspectives of agricultural recycling of sewage sludge in Rio de Janeiro State, 10 crops with the largest cultivated area in the state were surveyed and analyzed which of them are apt to receive sewage sludge as fertilizer and/or soil amendment. To determine the potential demand for sewage sludge in agriculture, the area occupied by these crops were multiplied by each fertilizer recommendation considering the sewage sludge as fertilizer. The analyzed sludge presented a high content of nutrients and organic matter and was included in the parameters of heavy metals, pathogenic agents, and bacteriological indicators stipulated by CONAMA Resolution No. 375/2006. The agricultural panorama of Rio de Janeiro State is favorable for agricultural recycling of sewage sludge since there is a great potential demand for this residue and, among the 10 agricultural crops with the

A amostragem da vegetação foi feita pelo método de parcelas, sendo registrado o diâmetro à altura do peito (DAP e a altura dos indivíduos > 1 m de altura. Os resultados indicaram que a floresta plantada apresenta menores valores de DAP médio e área basal, e maior densidade de troncos em relação à floresta natural. A distribuição de indivíduos por classes de altura e a distribuição de troncos por classes diamétricas mostraram que a floresta plantada é mais jovem. Laguncularia racemosa e Rhizophora mangle ocorreram em ambas as florestas, enquanto Avicennia schaueriana foi registrada apenas na floresta plantada. Laguncularia racemosa apresentou maior dominância e densidade relativa em todos os sítios analisados, provavelmente, por ser característica de locais com menor influência marinha e pelo fato do estuário ter sido alterado por perturbações antrópicas.

    The trace elements Zr, Y, Sr, U, Rb, Th, Ga, Pb, Zn, Cu, Ni, Co, Cr, Ce, Ba and La were determined by X-Ray fluorescence spectroscopy on samples from shales, carbonaceous shales, coal and fine-grained groundmass of a paraconglomerate ( pedra-areia ) colleted from the Papaleo and Faxinal outcrops and from the Faxinal Coal Mine, Guaiba, RS. The analysis pointed out an association of zirconium, copper, uranium and thorium with coal and carbonaceous rocks, whereas barium and galium are related to inorganic rocks. The other elements showed neither preferential relationships with organic nor inorganic matter. The extremely high contents of uranium, cerium and lanthanum in the upper coal layers in both Papaleo and Faxinal outcrops suggest an association with the top of the Rio Bonito Formation in this area.

    Full Text Available Rhipicephalus sanguineus, the brown dog tick, is responsible for maintaining and transmitting various pathogens, both in animals and human beings, and it is of great sanitary importance. This communication reports the first occurrence of Rhipicephalus sanguineus sensu lato parasitizing Rattus norvegicus in the state of Rio Grande do Sul, Brazil, and it is also the first record of this tick species parasitizing Rattus rattus in Brazil. The rodents were captured from the port area, located in the city of Pelotas, Rio Grande do Sul, Brazil. We collected 6 larvae of this tick species from 2 male R. rattus individuals, and 3 larvae from 2 female R. norvegicus individuals; parasitized specimens of both rodent species were captured from different sites within the experimental area. This record broadens the number of Rhipicephalus sanguineus sensu lato hosts in urban areas, indicating the need for continued monitoring on population density for both R. sanguineus and synanthropic rodents.

    Full Text Available The mesquite (Prosopis juliflora (Sw DC was established as a successful action of xerophilous introduction in Brazilian Northeast dry region. Its fruits are used in animal feed and the wood may be used as piles, firewood and charcoal. The species was introduced in 1942, spreading in "low areas" in Rio Grande do Norte, Paraiba, Pernambuco, Bahia and Piauí States. This article aims to elucidate how mesquite was introduced in Rio Grande do Norte State and to understand how it was spread. It was first introduced in Rio Grande do Norte State by the introduction experiments installed at São Miguel farm in the municipality of Angicos. The enthusiasm of technicians and researchers promoted the distribution of pods and seedlings on farms and cities in the state. In addition, there were government incentives to production, distribution and planting the species. This work aims to establish considerations to be used as historical basis on studies about this species and to consider aspects regarding current situation of this culture in Brazilian Northeast.

    Checklist of Social Wasps (Vespidae: Polistinae in Two Green Urban Areas in the Municipality of Barra Mansa, Rio de Janeiro, Brazil Abstract. New concepts on city planning and urbanization have progressively encouraged the creation and maintenance of public or private green areas, which are important feeding and shelter zones for several species of social wasps. However, in spite of the sampling effort and representativeness of southeastern Brazil, knowledge of richness and abundance of social wasps in Rio de Janeiro is still poor. The present study aimed at inventorying the fauna of social wasps in urban phytophysiognomies in downtown Barra Mansa, state of Rio de Janeiro, within the campus of Barra Mansa University. We sampled two areas for 12 months - a human-modified grassland and a reforested area, through active search with insect nests, Möericke traps, and aromatic traps. We collected 148 wasps of three tribes, four genera, and 17 species. Through active search we recorded 70.7% of the species sampled. The tribe Epiponini showed the highest species richness, and Polybia chrysothorax Lichtenstein and Polybia erythrothoraxla Richards were recorded for the first time in the state of Rio de Janeiro. In the anthropic field it was observed greater diversity (H’ = 1,890, equitability (J = 0,7605, and minor dominance (D(1/D = 0,2124, while in the reforested area was obtained H’ = 1,582, J = 0,6366 e D(1/D = 0,3465. The configuration and size of the reforested area in the campus Barra Mansa (UBM are insufficient elements to restrict the movement of species or segregate communities when considering the anthropic field, thereby still allowing that species could also be sampled between the areas.

    Summary Introduction Leprosy is a public health problem in Brazil where 31,044 new cases were detected in 2013. Rio Grande do Norte is a small Brazilian state with a rate of leprosy lower than other areas in the same region, for unknown reasons. Objectives We present here a review based on the analysis of a database of registered leprosy cases in Rio Grande do Norte state, comparing leprosy's geographic distribution among municipalities with local socio-economic and public health indicators and with historical documents about human migration in this Brazilian region. Results The current distribution of leprosy in Rio Grande do Norte did not show correlation with socio-economic or public health indicators at the municipal level, but it appears related to economically emerging municipalities 100 years ago, with spread facilitated by railroads and train stations. Drought-related migratory movements which occurred from this state to leprosy endemic areas within the same period may be involved in the introduction of leprosy and with its present distribution within Rio Grande do Norte. Conclusions Leprosy may disseminate slowly, over many decades in certain circumstances, such as in small cities with few cases. This is a very unusual situation currently and a unique opportunity for epidemiologic studies of leprosy as an emerging disease. PMID:26964429

Foram obtidos 20 blocos de esmalte bovino (3 mm × 3 mm × 3 mm. A metade da superfície de cada bloco foi coberta com esmalte de unhas. 10 blocos foram imersos em água e 10 em saliva humana por 12 horas. Após esse período, as peças foram imersas em vinho por 1 hora, submetidas ao ultra-som com acetona, lavados e secos. As peças foram analisadas em microscopia eletrônica de varredura. Em todos os blocos analisados foi possível observar erosão na superfície do esmalte. Em 2 blocos essa erosão foi leve, caracterizando-se como um alargamento das ranhuras fisiológicas do esmalte. No restante dos blocos ocorreu erosão severa, sendo possível observar o aspecto de favos de mel dos prismas de esmalte. O efeito erosivo no grupo de blocos imerso em saliva e em água foi similar. Concluiu-se que o vinho utilizado nesta experiência produziu erosão significativa na superfície do esmalte, in vitro. A imersão em saliva, precedente à exposição ao vinho, não pôde proteger o esmalte bovino contra a desmineralização, neste modelo experimental

    Full Text Available The purpose of this article is to discuss the role of Rock in Rio: The Musical, as herald of megafestival Rock in Rio. Driven by the success that musicals have reached in Brazil, we believe that the design of this spectacle of music, dance and staging renews the brand of the rock festival, once it adds the force of young and healthy bodies to its concept. Moreover, the musical provides Rock in Rio with some distance from the controversal trilogy of sex, drugs and rock and roll, a strong mark of past festivals around the world. Thus, the musical expands the possibilities of growth for the brand.

    Full Text Available Este estudo defende que o comportamento aleatório pode tornar-se legítimo objeto de estudo de uma ciência do comportamento. Analisamos inicialmente algumas considerações que B. F. Skinner formulou sobre o comportamento aleatório em suas Contingências do Reforço. Segundo Skinner (1969/1975, o comportamento aleatório "não apresenta interesse como processo de comportamento". Apresentamos uma rigorosa definição de "comportamento aleatório". Sustentamos que o comportamento aleatório pode constituir objeto de análise funcional, examinando alguns estudos empíricos que se têm conduzido sobre o comportamento aleatório. Apresentamos ainda algumas dificuldades empíricas e teóricas que podem afetar as investigações nessa área. Concluímos que o comportamento aleatório é um fascinante e importante tópico para uma completa ciência do comportamento.

    Full Text Available Issues related to company-community relations and the social license to operate have emerged as strategic business issues. This paper aims to contribute to the growing body of research on long-term company-community relations. An analysis of the relationship between Alcan (Aluminum of Canada, Montréal, Canada part of Rio Tinto since 2007 with the Cheslatta Carrier First Nation in the Kemano-Kitimat area of northern British Columbia, Canada, provides three contributions. The first is related to the notion of relational legacy, which refers to the sedimentation of unresolved issues that have the potential to impede the realization of corporate activities and the reproduction of low levels of social license to operate. The second concerns stakeholder management. While the literature suggests that stakeholders should be managed by companies according to the degree of salience, this analysis suggests that researchers and managers should consider the evolution of the environmental context in their analyses. Third, the analysis suggests that small or marginalized groups, depicted by the stakeholder management literature as dormant stakeholders, should not be underestimated.

  14. Musa's granite and Rio Maria's granodiorite Rb/Sr isotopic ages and geochemistry

    The Musa Granite and the Rio Maria Granodiorite are located at the eastern margin of the Amazonian craton, in the Rio Maria region, where a typical granite-greenstone terrain is characterized. Rb-Sr dating of six samples from different facies of Rio Maria Granodiorite furnished an age of 2564 ± 68 Ma with initial 87 Sr/ 86 Sr radio (IR) of 0.70288 ± 0.00092 (whole rock isochron; 1 ο error; MSWD = 2.26). Thirteen samples from the three facies of Musa Granite (monzogranites, syenogranites and intermediate to felsic hypabyssal rocks) gave Rb-Sr whole rock isochron with an age of 1692 ± 11 Ma and IR of 0.70777 ± 0.00023 (1 ο error, MSWD = 1.89). A preliminary attempt to individualize geochronologically the three facies was done resulting different ages and IRs. There is a coincidence between these ages and the emplacement sequence of these facies of the pluton. The actual meaning of the Rio Maria Granodiorite Rb-Sr age is still uncertain. It could be related to the end of the magmatic crystallization of the batholith as well as to the metamorphic-mylonitic event that affect it. Considering that the Jamon and Musa Granites are petrologically similar that they occur in the same area, it is interesting to note that latter is apparently a little older than the former. The IRs obtained for the two plutons are also not coincident. The isotopic Rb-Sr available data show that the exposed rocks of the Rio Maria Granodiorite have not been able to generate magmas with the compositions of the monzongranitic and the hypabyssal facies of the Musa pluton. On the other hand, rocks isotopically similar to the Rio Maria Granodiorite would theorically be able to generate the Jamon and a magma with the characteristics of the syenogranitic facies of the Musa pluton.

    2007-01-01

    The Odiel and Tinto rivers, southwest Spain, form a fully mixed estuary. An industrial area that includes a complex dedicated to the production of phosphate fertilizers is located by the Odiel River. This complex released phosphogypsum wastes directly to the Odiel River and also disposed them on open air piles located by the Tinto River. Due to new EU regulations, wastes are not directly released to the Odiel from 1998 on, although they are still disposed on the open air piles. The behavior of 226 Ra in a system like this estuary is complex, since radionuclides are affected by tidal actions and interactions with sediments through adsorption/desorption reactions and erosion/deposition processes. A numerical 2D depth-averaged model of the estuary has been developed, including processes mentioned above. It has been applied to reproduce experimental data measured after a release from the industrial complex in the Odiel River and after an accidental release in the Tinto River from the gypsum piles. The model has also been applied to simulate the self-cleaning process observed in the estuary after the direct releases from the fertilizer complex were stopped. (author)

    Full Text Available The objective of the study was to evaluate diversity and floristic similarity of Cerrado environments, under different levels of anthropization for agricultural usage and extractivism, and to generate a database to subsidize sustainable development proposals for the North region of Minas Gerais State, and traditional agriculture systems. Four areas with different levels of anthropization were sampled, in the following environments: “Areião, Areiãozinho, Chapada de Latossolo and Tabuleiro”, whose identifications had been made from key informers in the Água Boa Community, in Rio Pardo de Minas (MG, Brazil. The sampled units were distributed in 8 parcels of 20 x 50 m, with 5 subplots. The trees with circumference at ground level of 15 cm or bigger were measured. For analysis of the phytosociology indexes the following parameters were calculated for each environment: density, dominance, frequency, basal area, and importance value. For the floristic diversity the Shannon (H' was calculated, and for the analysis of similarity the index of Jaccard index (Sij. In all the environments, it was found a total of 477 individuals, distributed in 21 families, with 48 botanical species identified, and 27 individuals not identified. The five most important (importance value families was Fabaceae/Papilionoideae, Apocynaceae, Vochysiaceae, Sapotaceae and Fabaceae/Caesalpinoideae. And the ten most important species was Pouteria ramiflora, Dalbergia miscolobium, Hancornia speciosa, Macherium opacum, Sclerolobium paniculatum var. subvelutinum, Qualea grandiflora, Aspidosperma tomentosum, Byrsonima pachyphylla, Vochysia thyrsoidea and Hymenaea stigonocarpa. The H' index was of 3.01; 2.72; 2.48 and 2.09 for “Areião, Areiãozinho, Chapada de Latossolo and Tabuleiro”, respectively. The Sij index indicated a small floristic similarity for all the combinations between the environments.

Similarly, JNP grouped with the upper Orinoco river and Guiana is the sister-group in the area cladogram with strongest support. Different sub-groups of species reveal area cladograms with different topologies, suggesting complex scenarios of avifauna diversification. These scenarios may have been influenced by geological events occurring during the Miocene and Pleistocene. In this study was identified an area of endemism previously not described for the Amazon, the Rio Negro endemic area. The avifauna of PNJ is representative of the northwestern and western Amazon and has taxa with distributions restricted to the central region of the Amazon, reinforcing its importance in protecting the biodiversity of the Amazon.

  6. Culex quinquefasciatus from Rio de Janeiro Is Not Competent to Transmit the Local Zika Virus.

    Full Text Available The Americas have suffered a dramatic epidemic of Zika since May in 2015, when Zika virus (ZIKV was first detected in Brazil. Mosquitoes belonging to subgenus Stegomyia of Aedes, particularly Aedes aegypti, are considered the primary vectors of ZIKV. However, the rapid spread of the virus across the continent raised several concerns about the transmission dynamics, especially about potential mosquito vectors. The purpose of this work was to assess the vector competence of the house mosquito Culex quinquefasciatus from an epidemic Zika area, Rio de Janeiro, Brazil, for local circulating ZIKV isolates.Culex quinquefasciatus and Ae. aegypti (positive control of ZIKV infection from Rio de Janeiro were orally exposed to two ZIKV strains isolated from human cases from Rio de Janeiro (Rio-U1 and Rio-S1. Fully engorged mosquitoes were held in incubators at 26 ± 1°C, 12 h:12 h light:dark cycle and 70 ± 10% humidity. For each combination mosquito population-ZIKV strain, 30 specimens were examined for infection, dissemination and transmission rates, at 7, 14 and 21 days after virus exposure by analyzing body (thorax plus abdomen, head and saliva respectively. Infection rates were minimal to completely absent in all Cx. quinquefasciatus-virus combinations and were significantly high for Ae. aegypti. Moreover, dissemination and transmission were not detected in any Cx. quinquefasciatus mosquitoes whatever the incubation period and the ZIKV isolate. In contrast, Ae. aegypti ensured high viral dissemination and moderate to very high transmission.The southern house mosquito Cx. quinquefasciatus from Rio de Janeiro was not competent to transmit local strains of ZIKV. Thus, there is no experimental evidence that Cx. quinquefasciatus likely plays a role in the ZIKV transmission. Consequently, at least in Rio, mosquito control to reduce ZIKV transmission should remain focused on Ae. aegypti.

The work on the project includes the planning and management of a number of background environmental studies. The company has also commissioned studies by external consultants into process technologies, mining strategies and techniques for extracting the uranium ore from the waste rock. In addition, Canning Resources has made a detailed assessment of the worldwide market potential for Australian uranium in the late 1990s and into the 21st century. The most significant factor affecting the future of this project is the current product price. This price is insufficient to justify the necessary investment to bring this project into production

    Estuaries are sinks of materials and substances which are released directly into them or transported from rivers that drain the basin. It is usual to find high organic matter loads and fine particles in the sediments. We analyzed radionuclide concentrations ("2"1"0Po, "2"3"0Th, "2"3"2Th, "2"3"4U, "2"3"8U, "2"2"6Ra, "2"2"8Th, "2"2"8Ra, "4"0K) in sediments and three different organs (roots, stems and leaves) of three species of halophytes plants (Spartina maritima, Spartina densiflora and Sarcocornia perennis). The study was carried out in two tidal salt marshes, one polluted by U-series radionuclides and another nearby that was unpolluted and was used as a control (or reference) area. The Tinto River salt marsh shows high levels of U-series radionuclides coming from mining and industrial discharges. On the contrary, the unperturbed Piedras River salt marsh is located about 25 km from the Tinto marsh, and shows little presence of contaminants and radionuclides. The results of this work have shown that natural radionuclide concentrations (specially the U-isotopes) in the Tinto salt marsh sediments are one order of magnitude higher than those in the Piedras marsh. These radionuclide enhancements are reflected in the different organs of the plants, which have similar concentration increases as the sediments where they have grown. Finally, the transfer factor (TF) of the most polluted radionuclides (U-isotopes and "2"1"0Po) in the Tinto area are one order of magnitude higher than in the Piedras area, indicating that the fraction of each radionuclide in the sediment originating from the pollution is more available for the plants than the indigenous fraction. This means that the plants of the salt marshes are unhelpful as bioindicators or for the phytoremediation of radionuclides. - Highlights: • Radionuclides were analyzed in sediments and plants in unpolluted salt marshes. • Plants uptake radionuclides in all organs in both salt marshes. • The transfer factors

    Full Text Available This paper proposes to discuss the transformation of urban landscapes in the Paraíba River Valley as members of the coffee elite emerged in this area and a specific landscape configuration was projected there based on the use of imperial palms ( Roystonea oleracea. Chronologically speaking, the paper covers a period from 1808 to 1911; with regard to space, it focuses on the stretch between Rio de Janeiro and São Paulo, with a closer look at the case of the city of Lorena (SP, so as to encompass all the changes that took place in this region from the introduction to the decline of coffee growing as an economic activity. The urban changes during this period were accompanied by the advent and consolidation of landscapes typical of the society of coffee growers: streets lined with palm trees, a token of their close connections with the royal court, a display of their adherence to “Frenchified customs”. Such configurations were used to characterize public areas and raise them to the same status as the new buildings that gradually replaced those built in colonial style. The paper is structured around three key moments, namely: the introduction of imperial palms in Rio de Janeiro and their association with the idea of nobility and rank, and consequently with neoclassical architecture, which was brought to the colony by the 1816 French Mission; the dissemination of the use of imperial palms as a landscaping resource typical of public spaces from the royal court to the capital of São Paulo, particularly by the coffee barons during the second period of monarchic rule; and, finally, the hypothesis that the use of imperial palms to embellish public areas in São Paulo may have been introduced by a Lorena citizen associated with the coffee elite, albeit later, when Brazil was already a republic

    Full Text Available Descreve-se um surto de mortalidade em bovinos por Babesia bovis em abril de 2007, no Município de Picada Café, Rio Grande do Sul. Em um rebanho com 55 novilhas, 28 (50,9% morreram em cinco dias. A doença iniciou vinte dias após o ingresso dos bovinos na propriedade. Os sinais clínicos incluíam febre, incoordenação, agressividade, anemia, petéquias nas mucosas e morte 1 á 2 dias após. Em 4 animais necropsiados, observaram-se palidez de mucosas, hemorragias múltiplas, esplenomegalia, fígado aumentado e alaranjado, vesícula biliar com parede edemaciada e contendo bile grumosa. Os rins estavam vermelho-escuros e a bexiga continha urina cor de vinho tinto. O encéfalo apresentou cor róseo-cereja externamente e ao corte, mais marcado no córtex telencefálico, cerebelo e corpo estriado, contrastando com a cor branca da substância branca. Na histologia havia nefrose hemoglobinúrica, necrose hepática paracentral, bilestase canalicular, congestão esplênica, além de congestão com grande quantidade de eritrócitos parasitados por estruturas compatíveis com Babesia bovis na região cortical do encéfalo, também observadas em esfregaços teciduais dessas regiões. A morte de 28 bovinos em 5 dias deveu-se, provavelmente, à falta de imunidade contra o parasito. O tratamento foi realizado com dipropionato de imidocarb nos demais animais, havendo recuperação dos bovinos que apresentavam sinais iniciais leves e não ocorrência de novos casos durante um período de dois meses, quando foram enviados para abate.An outbreak of cattle mortality due to Babesia bovis infection in the county of Picada Café, Rio Grande do Sul, southern Brazil, in April 2007 is described.

    Full Text Available Neste artigo consideramos os problemas ambientais globais dentro do conceito de limiares planetários, em convergência com os últimos avanços das ciências naturais. Nesse contexto, nosso objetivo é explorar o papel do Brasil na governança do espaço de operação seguro para a humanidade, avaliando como o país complementa o enorme capital ambiental físico que possui com ações políticas específicas orientadas para uma economia verde de baixo carbono (EVBC, tanto no âmbito doméstico quanto no internacional. Para atingir essa meta, em primeiro lugar discutimos conceitualmente a economia verde de baixo carbono como paradigma de desenvolvimento compatível com um espaço de operação seguro para a humanidade; em segundo lugar, analisamos a Rio+20 pelo prisma da governança global dos limiares planetários e pela atuação brasileira na Cúpula; e finalmente fazemos um diagnóstico da situação do Brasil em relação ao novo paradigma de desenvolvimento. Como conclusões da análise, destacamos a crescente distância entre a aceleração dos problemas da interdependência - especialmente a definição de um espaço seguro de operação para a humanidade - e os mecanismos globais de governança existentes, derivada de um sistema internacional bloqueado e dominado por forças conservadoras. O resultado frustrante da Rio+20 é evidência clara dessa defasagem. Nessa dinâmica, o Brasil tem o potencial para ser um ator central da governança dos limiares planetários, por seu vasto capital ambiental físico. No entanto, o mínimo avanço da EVBC no país degrada essa capacidade de agência, e o torna uma potência ambiental subdesenvolvida (underachiever environmental power.

    identify areas of the Municipality where the risk of these occurrences is highest. The study also sought to identify trends and seasonal patterns of this mortality and to place violence within the ambit of public health through application of the epidemiologic surveillance approach. Information on mortality was extracted from death certificates provided by the State Health Secretariat of Rio de Janeiro. A total of 20 224 death certificates were studied. The populations used as the denominators for determining rates were estimated from the censuses of 1980 and 1991. For purposes of the analysis, the Municipality was divided into eight programmatic areas, each composed of diverse neighboring districts. A time series analysis was done for traffic accidents and homicides. The results showed that external causes were the leading causes of death in the 10-19 age group, and that during the study period deaths from these causes had increased, especially among males. The results also revealed that mortality was heterogeneously distributed in areas of the Municipality that differed socioeconomically. The study points to the need for better integration of the health sector with other sectors and institutions and for a restructuring of the health system with regard to epidemiologic surveillance of violence.

    Full Text Available This study was designed to analyse the clinical and epidemiological data from human parvovirus B19 cases in a six-year study of rash diseases conduct in an urban area in Brazil (Niterói city area, State of Rio de Janeiro. A total of 673 patients with acute rash diseases were seen at two primary health care units and at a general hospital. A clotted blood sample was collected from all subjects at the time of consultation. Forty-nine per cent (330 cases of the patients were negative for dengue, rubella and measles IgM or for low avidity IgG to HHV-6. Of these 330, 105 (31.8% were identified as IgM positive to parvovirus B19 by using an antibody capture EIA. During the study period, three distinct peaks of parvovirus infection were detected, suggesting that the disease appears to cycle in approximately 4-5 years. B19 infection was characterized by variable combinations of fever, flu-like symptoms, arthropathy, and gastrointestinal symptoms. Frequency of fever and arthropathy was substantially higher in adults, 75% [chi2 (1 D.F. = 11.39, p = 0.0007] and 62.5% [chi2 (1 D.F. = 29.89, p = 0.0000], respectively. "Slapped-cheek" appearance and reticular or lace-like rash were seen in only 30.1% of the children. No adult presented this typical rash. The lack of the typical rash pattern in a large proportion of parvovirus B19 and the similarity of clinical manifestations to other rash diseases, specially to rubella, highlight the difficulty of diagnosing B19 infection on clinical grounds alone.

    The geological results obtained in the Candiota Region by NUCLEBRAS, during the evaluation of the uranium economic potential from basal Gondwana Sequence - Itarare Group and Rio Bonito Formation - at South-East of the Parana Sedimentary Basin, are studied. The analysis of 18 geologic sections (scales 1:5.000 x 1:500), 21 drill holes and fotogeologic interpretation in the scale 1:50.000, are included. The Itarare Group sedimentation was conditioned by paleo - relief with valleys formed from differential erosion on 'horst - graben' structures. The deposition of its rhythmites, diamictites and siltstones was made in periglacial and marine environments. The sedimentation of the Rio Bonito Formation is related to the main Itarare Group depositional axes. The typical lithologies are: sandstones, siltstones, mudstones and coals, representing progradational fluvial sediments over coastal - plain areas. (Author) [pt

    Dredging is employed quite frequently in the state of Rio de Janeiro, especially for the installation and upkeep of commercial ports and rehabilitation of the hydraulic section of silted bodies of water. Until recently, all dredged material with no economic use was destined for marine disposal or stored at the edge of the water body. Since the 1990s, however, a new approach has been adopted for dredging as a result of pressure from the environmental organisations, encouraging closer interaction in Rio de Janeiro between the local and state public authorities and the universities on issues relating to licensing of this kind of activity. The recent experiments of the Civil and Ocean Engineering Programs of COPPE-UFRJ (Federal University of Rio de Janeiro) described herein are included in this context. The state of Rio de Janeiro has three bays, several coastal lagoon systems and a number of small and medium sized rivers in or close to urban areas, with a gentle slope as they near the sea. This is, then, a region highly susceptible to silting processes of water bodies, and therefore, to maintenance and/or environmental rehabilitation. As discussed in the article, fine and almost always organic sediments prevail, which is a considerable obstacle to the end disposal and possibility of reuse.

Com base em dados de sensores remotos e verificação de campo, foi realizado mapeamento geomorfológico da planície do rio Paraguai no trecho entre as confluências dos rios Cuiabá e Miranda, onde foram reconhecidas formas deposicionais atuais e antigas. A análise das associações de formas permitiu estabelecer proposta de evolução geomorfológica para a área, mas os eventos carecem ainda de datação precisa por métodos geocronológicos. Uma rede de drenagem abandonada multicanais está parcialmente preservada na planície, sendo composta por formas de canais com diques marginais que evidenciam período de menor descarga fluvial, provavelmente do Pleistoceno tardio ao Holoceno inferior. Um sistema constituído por paleocinturões de meandros trunca a paleorrede de drenagem multicanais, registrando aumento na umidade e na descarga fluvial. Sob essas condições o rio Paraguai construiu um sistema composto por cinturões de meandros com direção aproximada norte-sul no Holoceno inferior/médio. Agradação dos cinturões favoreceu importante evento de avulsão, com a mudança do curso do rio Paraguai para o cinturão de meandros atual no Holoceno superior. As gerações de formas identificadas e mapeadas resultaram num padrão de sobreposição de diferentes estilos fluviais, que registram significativas mudanças hidrológicas na planície desde o Pleistoceno tardio.

    Full Text Available Rio de Janeiro, Brazil, experienced a severe dengue fever epidemic in 2008. This was the worst epidemic ever, characterized by a sharp increase in case-fatality rate, mainly among younger individuals. A combination of factors, such as climate, mosquito abundance, buildup of the susceptible population, or viral evolution, could explain the severity of this epidemic. The main objective of this study is to model the spatial patterns of dengue seroprevalence in three neighborhoods with different socioeconomic profiles in Rio de Janeiro. As blood sampling coincided with the peak of dengue transmission, we were also able to identify recent dengue infections and visually relate them to Aedes aegypti spatial distribution abundance. We analyzed individual and spatial factors associated with seroprevalence using Generalized Additive Model (GAM.Three neighborhoods were investigated: a central urban neighborhood, and two isolated areas characterized as a slum and a suburban area. Weekly mosquito collections started in September 2006 and continued until March 2008. In each study area, 40 adult traps and 40 egg traps were installed in a random sample of premises, and two infestation indexes calculated: mean adult density and mean egg density. Sera from individuals living in the three neighborhoods were collected before the 2008 epidemic (July through November 2007 and during the epidemic (February through April 2008. Sera were tested for DENV-reactive IgM, IgG, Nested RT-PCR, and Real Time RT-PCR. From the before-after epidemics paired data, we described seroprevalence, recent dengue infections (asymptomatic or not, and seroconversion. Recent dengue infection varied from 1.3% to 14.1% among study areas. The highest IgM seropositivity occurred in the slum, where mosquito abundance was the lowest, but household conditions were the best for promoting contact between hosts and vectors. By fitting spatial GAM we found dengue seroprevalence hotspots located at the

    Full Text Available The aim of this research was to evaluate the quality of groundwater in areas of permanent preservation (Guarani Aquifer System – GAS in the Rio Pardo Hydrographical Basin, RS, Brazil, using physical, chemical and microbiological variables, based on resolution no. 396/2008 of the National Council on the Environment - CONAMA. Nine sampling points were distributed throughout the basin, where groundwater was classified as the major ions through the Piper diagram. The results indicated that most of the wells evaluated were classified in Class 4, accounting for water uses less restrictive. However, it should be considered that the aquifers are characterize by different geological conditions, having intrinsical physical, chemical and biological variables with hydrogeochemical variations, requiring that their quality levels are often based on these characteristics, as noted in diagram Piper, where the samples P1, P2, P3, P5 and P9 were classified as calcium bicarbonate, the waters of the points P4, P6, P7 as sodium bicarbonate and P8 as sulfated. It was found that the quality of water from wells with depths less than 6 m are becoming more vulnerable due to anthropogenic activities, as showing by the concentration of nitrate, total and thermotolerant coliforms, while the quality of water from deeper wells basically depends on their hydrogeological and hydrogeochemical characteristics based on the concentration of sodium and sulfate variables. However, they also showed contamination by human activities, mainly by the nitrate variable.

Por outro lado, o reduzido número de voçorocas (33 e a presença de pacotes sedimentares poucos espessos (média de 7 metros, apontam a baixa efetividade dos processos mecânicos na bacia, sobretudo ao compararmos com a sub-bacia do rio Piracema, tributária do rio Bananal, com 117 voçorocas, terraços de até 23 metros de espessura e apenas 1 depressão fechada. Internamente, a bacia do rio Turvo apresentou variações, onde, de modo geral, a sub-bacia do rio das Pedras concentrou 21 das 33 voçorocas ativas, os mais espessos pacotes fluviais e apenas 16 depressões fechadas.

Os animais foram introduzidos em área alagada e desenvolveram lesões cutâneas ulcerativas e úmidas, de tamanhos variados, localizadas na região distal dos membros e no chanfro nasal. Histologicamente, as lesões eram caracterizadas por múltiplos granulomas com hifas intralesionais, melhor observadas pela coloração de metenamina nitrato de prata de Gomori, e circundadas por abundante tecido conjuntivo fibroso. O diagnóstico foi realizado com base na epidemiologia, lesões macroscópicas e histológicas e pela reação imuno-histoquímica positiva com anticorpo policlonal anti-Pythium insidiosum. A morbidade foi de 23,8% e os animais adoeceram 15-90 dias após a introdução na área alagada. Em todos os casos as lesões evoluíram para a cura sem tratamento. Sugere-se que a doença possa ser mais frequente em bovinos do que se supõe, principalmente em áreas alagadas da região Sul do Rio Grande do Sul.An outbreak of cutaneous pythiosis is described in cattle from southern Rio Grande do Sul, Brazil. Cattle were introduced into flooded pastures and developed ulcerative and wet cutaneous lesions on distal limbs and Planum nasale. Histologically, the lesions were characterized by multiple granulomas with intralesional hyphae, better seen in the methenamine silver stain, and surrounded by abundant fibrous tissue. Diagnosis was based on epidemiology, gross and histological lesions, and by positive immuno-histochemical reaction with anti-Pythium insidiosum polyclonal antibody. Morbidity was 23.8% and lesions were observed 15-90 days after cattle were introduced in the flooded area. Affected cattle had spontaneous healing without treatment. It is suggested that the disease is more frequent than what was earlier thought, mainly in flooded areas of the Southern region of the Rio Grande do Sul State.

    The 2005 Mars Astrobiology Research and Technology Experiment (MARTE) project conducted a simulated 1-month Mars drilling mission in the Río Tinto district, Spain. Dry robotic drilling, core sampling, and biological and geological analytical technologies were collectively tested for the first time for potential use on Mars. Drilling and subsurface sampling and analytical technologies are being explored for Mars because the subsurface is the most likely place to find life on Mars. The objectives of this work are to describe drilling, sampling, and analytical procedures; present the geological analysis of core and borehole material; and examine lessons learned from the drilling simulation. Drilling occurred at an undisclosed location, causing the science team to rely only on mission data for geological and biological interpretations. Core and borehole imaging was used for micromorphological analysis of rock, targeting rock for biological analysis, and making decisions regarding the next day's drilling operations. Drilling reached 606 cm depth into poorly consolidated gossan that allowed only 35% of core recovery and contributed to borehole wall failure during drilling. Core material containing any indication of biology was sampled and analyzed in more detail for its confirmation. Despite the poorly consolidated nature of the subsurface gossan, dry drilling was able to retrieve useful core material for geological and biological analysis. Lessons learned from this drilling simulation can guide the development of dry drilling and subsurface geological and biological analytical technologies for future Mars drilling missions.

    Full Text Available The land tenure has been a challenge for the management of protected areas in Brazil, mainly those located in urban areas, such as the ‘Pedra Branca’ State Park (PEPB in the west of Rio de Janeiro city. To ensure an adequate management of UC, this paper presents a land tenure analysis for support the Management Plan of PEPB. Based on the secondary data and application of structured questionnaires (316 interviews, representing 29% of the total estimated housing on the land tenure in areas inside/around of PEPB boundaries, seeking for some key elements to support the management of PEPB. This survey identified six zones (Z with some types of occupation in the study area. The results showed that there are diversified occupations, such as residents with high, medium and low income, including ‘favelas’, subsistence agricultures and temporary residents. This work pointed out to a complexity related to the land tenure in protected areas and highlights the required elements: (i systematic data survey for the complete registration of properties in PEPB; (ii organization of a multi-interdisciplinary working groups to solve land tenure problems, (iii implementation of environmental education and communication programs, seeking explanation on the PEPB conservation as a factor of improving the quality of life, (iv agreements between the residents of the Park and policy makers to minimize the conflicts caused by the land tenure in PEPB.

Participaram da pesquisa sessenta universitários do Rio de Janeiro, de ambos os sexos, entre 17 e 30 anos. Utilizamos um questionário com perguntas abertas, no qual eles apresentaram seus familiares. O material obtido foi analisado em termos temáticos e estatísticos. Entre os usuários de maconha, prevaleceu a autoridade e a ênfase nos papéis sociais, sendo a interação familiar marcada pelo acento emocional e pela idealização. Entre os não-usuários a autoridade coexistiu com relações interpessoais de companheirismo e partilha, num contexto familiar em que predominaram não aspectos afetivos mas práticas de proteção e cuidados. Podemos afirmar que o papel da família na prevenção ao uso de drogas está associado à promoção da autonomia, diferenciação e garantia de um espaço próprio para o jovem.The objective of this paper was to study the family context among marijuana users and non-users.

    The Taciba and Rio Bonito ('lower' Triunfo Mbr) formations are divided into six depositional sequences based on cores, gamma-ray and electrical logs from shallow drillings from northern Santa Catarina State, Brazil. Each sequence is formed by two systems tracts, a lower one, sandy (low stand) and an upper one, shaly (high stand). The Taciba Formation has three sequences, S{sub 0} to S{sub 2}; sequence S{sub 0} has a thick turbidite sandstone at the base (Rio Segredo Member) that pinches out towards the eastern margin and even disappears in the Mafra outcrop area. Sequence S{sub 1} varies from a thin fluvial-estuarine system to a thick turbidite sandstone of a channelled fan system; S{sub 1} upper shaly system tract is marine in well PP-11, and it is glacially influenced in well PP-10. Sequence S{sub 2} is a thick sandstone body of shallow marine origin, but restricted to one well (PP-11); its upper shaly tract is dominated by massive siltstones intercalated with thin, distal tempestites. The 'lower' Triunfo Member (or 'Taciba- Triunfo transition') begins with the arrival of deltaic clastics of sequence S{sub 3} lower tract, coarsening-up from medial- to proximal delta front sandstones. Sequence S{sub 4} is quite similar to S{sub 3}, both showing sandstone pro gradation from north to south, as opposed to the southwest-sourced transgressive diamictites. Sequence S{sub 5} consists of fluvial deposits at well PP-12, and two transgressive cycles from wells PP-11 to PP-9, each one of them composed of fluvial-estuarine to marine systems. Well PP-10 is an exception, where the lower cycle presents de glaciation to marine deposits. (author)

    Surveys in the coastal sandy plains (restingas) of Rio de Janeiro have shown a great richness of galls. We investigated the galling insects in two preserved restingas areas of Rio de Janeiro state: Parque Estadual da Costa do Sol and Reserva Particular do Patrimônio Natural Fazenda Caruara. The collections were done each two months, from June 2011 to May 2012. We investigated 38 points during 45 minutes each per collection. The galls were taken to the laboratory for rearing the insects. A total number of 151 insect galls were found in 82 plant species distributed into 34 botanic families. Most of the galls occurred on leaves and the plant families with the highest richness of galls were Myrtaceae and Fabaceae. All the six insect orders with galling species were found in this survey, where Cecidomyiidae (Diptera) was the main galler group. Hymenoptera and Thysanoptera were found as parasitoids and inquilines in 29 galls. The richness of galls in the surveyed areas reveals the importance of restinga for the composition and diversity of gall-inducing insect fauna.

    Full Text Available ABSTRACT This study surveyed species of the family Araceae in Grumari restinga, located in the metropolitan region of the city of Rio de Janeiro, Brazil. We aimed to: i evaluate the contribution of a single locality (Grumari restinga to regional conservation (Rio de Janeiro State of Araceae; and ii compare the distribution of species of Araceae among restingas of the state. We calculated the extent of occurrence and the area of occupancy in the entire state for eight species of Araceae found in Grumari,and performed a similarity analysis among restingas. Our data demonstrate that the extent of occurrences for Anthurium augustinum, A. coriaceum and A. maricense are influenced by Grumari because this area is the boundary of their known distribution in the state. Grumari did not have an influence on the distribution of the other studied species. We found Anthurium coriaceum, A. luschnathianum and Philodendron crassinervium to exhibit unusual habits as terrestrial plants in sandy soil. The similarity analysis identified six groups of Araceae, four of which are related to the distance from adjacent forests. We demonstrated that this small conservation unit represents a key locality in the preservation of natural populations of species of Araceae in Rio de Janeiro State.

    The U.S. Geological Survey, in cooperation with the New Mexico Interstate Stream Commission, developed a geodatabase compendium (hereinafter referred to as the 'geodatabase') of available water-resources data for the reach of the Rio Grande from Rio Arriba-Sandoval County line, New Mexico, to Presidio, Texas. Since 1889, a wealth of water-resources data has been collected in the Rio Grande Basin from Rio Arriba-Sandoval County line, New Mexico, to Presidio, Texas, for a variety of purposes. Collecting agencies, researchers, and organizations have included the U.S. Geological Survey, Bureau of Reclamation, International Boundary and Water Commission, State agencies, irrigation districts, municipal water utilities, universities, and other entities. About 1,750 data records were recently (2010) evaluated to enhance their usability by compiling them into a single geospatial relational database (geodatabase). This report is intended as a user's manual and administration guide for the geodatabase. All data available, including water quality, water level, and discharge data (both instantaneous and daily) from January 1, 1889, through December 17, 2009, were compiled for the study area. A flexible and efficient geodatabase design was used, enhancing the ability of the geodatabase to handle data from diverse sources and helping to ensure sustainability of the geodatabase with long-term maintenance. Geodatabase tables include daily data values, site locations and information, sample event information, and parameters, as well as data sources and collecting agencies. The end products of this effort are a comprehensive water-resources geodatabase that enables the visualization of primary sampling sites for surface discharges, groundwater elevations, and water-quality and associated data for the study area. In addition, repeatable data processing scripts, Structured Query Language queries for loading prepared data sources, and a detailed process for refreshing all data in the

    Here we describe results from a tracer test in the Cerros del Rio basalt beneath Mesita del Buey, Technical Area 54 (TA-54) at Los Alamos National Laboratory (LANL or the Laboratory). This report follows from plans outlined in our previous Tracer Test Work Plan (LANL 2016). These activities were conducted by LANL to further characterize subsurface properties of the Cerros del Rio basalts at Material Disposal Area (MDA) L (Figure 1.1-1). The work presented follows from the “Interim Measures Work Plan for Soil-Vapor Extraction of Volatile Organic Compounds from Material Disposal Area L, Technical Area 54, Revision 1,” submitted to the New Mexico Environment Department (NMED) in September 2014 (LANL 2014). Remediation of the MDA L vapor plume by soil-vapor extraction (SVE) is recommended as part of the final remedy in the “Corrective Measures Evaluation Report for Material Disposal Area L, Solid Waste Management Unit 54-006, at Technical Area 54, Revision 2” to meet a remedial action objective of preventing groundwater from being impacted above a regulatory standard by the transport of volatile organic compounds (VOCs) to groundwater through soil vapor (LANL 2011).

    Full Text Available A reference inventory of prehistoric marine mollusks from the Rio das Ostras region was created based on an excavation carried out at the Sambaqui da Tarioba shellmound. Patterns of richness and biogeography were studied, and the representativeness of bivalve and gastropod diversities found at this archaeological site were inferred. A total of 47 taxa belonging to 28 families, most of which from unconsolidated substrates, was identified. The shellmound species composition does not differ from the present-day composition. All recorded species are characteristic of a wide transition zone between the south of the states of Espírito Santo (21°S and Rio Grande do Sul (32°S. Thus, the data show little evidence of evolution in the composition, richness,and biodiversity distribution patterns of mollusks in the Rio das Ostras region. Likewise, a reconstitution of the paleoenvironment from the functional characteristics of the shellmound species indicates that the locality's geomorphology and climate remained largely unchanged in the last 4,000 years BP.

    The Rio Bermudez micro-basin makes up part of the principal hydrological resource area in the Central Region of Costa Rica. For this reason a study was done to determine the availability of hydrological resources in said micro-basin to identify areas with potential water availability problems. A monthly water balance was calculated using land use, geomorphology and climate parameters. From these water balance studies, the amount of available water was calculated and classified into four categories, however, in this micro-basin, only three categories were identified: high, medium and moderate water availability. No areas were identified with low water availability, indicating availability is sufficient; however, there is increasing demand on water resources because over half of the micro-basin area is classified as having moderate water availability.

The surveys were conducted monthly between June 2011 and May 2012. Additional ad libitum observations were made between February 2008 and July 2012. We recorded 76 waterbird species of 15 families, of which Scolopacidae was the most representative, with 15 species. The high Nearctic shorebird species richness observed in coastal lagoons in Quissama (17 species is an evidence of the important role of the region as staging site for migratory birds at national level. Also, nine of the species recorded are threatened at regional and one is threatened at national level. It should be emphasized that three species considered locally extinct in the municipality of Rio de Janeiro, the most extensively surveyed area in the State, were recorded in the present study. Additionally, we present a high number of previously unrecorded species in northern Rio de Janeiro, and report the first documented record of Stercorarius pomarinus in Rio de Janeiro State.

Soil sample preparations were compared by using ultrasound, microwave assisted extraction and Soxhlet extraction. Recoveries of matrix spiked samples ranged from 70 to 130%. Analysis of a certified soil material showed recoveries ranging from 71 to 234%. Although low concentrations of organochlorine residues were found in water and soil samples, this area is of environmental importance and concern, thus demanding a monitoring program of its compartments. - Highlights: → The organochlorine pollutants occurrence in the Atlantic Rain Forest was investigated. → PARNASO was considered a control area of environmental quality. → Extractions methods were compared for typical C-rich soils samples from Brazil. → Low concentrations of organochlorine residues were found in water and soil samples. → A monitoring program is demanded due to the environmental importance of the area. - The occurrence of organochlorine pollutants in soils of the Atlantic rainforest fragments in Rio de Janeiro, Brazil demands a monitoring program of its compartments.

    Full Text Available High School education in Rio Grande do Sul underwent reformulations with the proposal for Polytechnic Intermediate Education suggested by the State Education Office. Overall, this proposal arose from the demand for improvements in elementary education, where High School education is concerned, and was implemented along the years of 2012, 2013 and 2014. Among the desired improvements was the need to overcome content education through interdisciplinarity and an integrated curriculum. Taking such changes into consideration – which implied the creation of knowledge areas, curricular restructuring, changes to the means of evaluation and the planning and teaching methodology presumptions – this article aims to report the path and results from research that proposed to investigate the manner in which interdisciplinarity began being constructed by educators in the area of Nature Sciences from faculty expertise. The methodology employed was of ethnographic research, that allowed to gather a wealth of data and opinions from the individuals investigated, namely nine teachers from the Nature Sciences area that encompasses the subjects of chemistry, physics and biology, from two intermediate education public schools in Northern Rio Grande do Sul. Data interpretation was carried out under the perspective of Discursive Textual Analysis and allowed for the identification of both the hurdles that made interdisciplinary construction and action unfeasible, such as lack of time for planning, and possible alternatives to overcome such hurdles, among which faculty expertise. From the discussion of those results, it can be observed that the proposal for Polytechnic High School provided space for the construction of the interdisciplinary praxis as well as for reflecting on and awareness building of its need, making it feasible from theoretic-methodological (reoptions on the part of the faculty in the bias of their expertise as such.

Adotando a postura prospectiva que informou todo esse projeto, o artigo indica algumas das linhas de força que deverão estabelecer o elo entre o sistema internacional presente e o que haverá no futuro, em um horizonte de vinte anos, destacando entre outros o papel dos EUA, da Europa e da China nesse processo. Quatro cenários são utilizados como base para a análise do caso brasileiro: Desconcentração conflituosa, Multipolaridade benigna, Unipolar consolidado e Ordem liberal cosmopolita. Considera-se aqui o Brasil como um país intermediário, afastado das áreas críticas de tensão internacional, e que, portanto, dispõe de certa margem de manobra e razoável condição para definir suas estratégias internacionais.THIS article presents part of the results of a broad research about Brazil and international scenarios. Assuming the same prospective view of the research project, this article indicates a few current driving forces that will contribute to define international order in the future, in a 20 years perspective. The roles of the USA, Europe and China are highlighted in this analysis. Four scenarios are used as parameters for the analysis of the Brazilian case: conflictive deconcentration, benign multipolarity; consolidated unipolarity and cosmopolitan liberal order. We consider Brazil as an Intermediate State out of the critical areas of international conflict. We also consider that Brazil has certain margin for maneuver and reasonable amount of capacity to define its international strategies.

Universidade Federal Fluminense, Vital Brazil, Niterói, RJ, Brazil. E-mail: nathaliecunha@id.uff.br Toxoplasmosis is a serious public health problem worldwide as it can cause prenatal and neonatal morbidity and mortality in humans. Although dogs are not definitive hosts of T. gondii, they play an important role in the mechanical dissemination of oocysts. This study aimed to carry out a seroepidemiological investigation of anti-Toxoplasma gondii antibodies in domestic dogs from seven municipalities in the state of Rio de Janeiro, Brazil. A crosssectional epidemiological study was carried out to evaluate the profile of anti-Toxoplasma gondii IgG antibodies in dogs from canine sera from different municipalities in the state of Rio de Janeiro. The municipalities studied were Cachoeiras de Macacu, Guapimirim, Itaboraí, Magé, Resende, Seropédica and Silva Jardim. The detection of antibodies of the IgG class anti-Toxoplasma gondii was performed using the indirect enzyme immunoadsorption (ELISA assay and the statistical analyzes used were the chi-square test and the prevalence ratio. Of the 651 samples tested, 300 were reactive for T. gondii, representing a relative frequency of 46.08% of seroreactive dogs. It was concluded that dogs are good sentinels for evaluations of risk for occurrence of T. gondii, emphasizing those coming from rural areas and that there was no difference in the occurrence of serorreative dogs in front of different municipalities studies of the state of Rio de Janeiro.

    Woody vegetation from 23 forest stands along the Upper Rio Negro of Venezuela and Colombia was sampled in 1982 to examine the hypothesis that the Amazon forest has been largely undisturbed since the Pleistocene, to quantify vegetation development during different stages of succession following agricultural development, and to determine the time required for a successional stand to become a mature forest. The ubiquitousness of charcoal in the tierra firme forest indicated the presence of fire associated with extreme dry periods and human disturbances. Changes in species composition, vegetation structure, and woody biomass were studied on 19 abandoned farms and four mature forest stands. Living and dead biomass for the tress and their components was determined by regression equations developed from measurements of harvested trees. The rate of recovery of floristic composition, structure, and biomass following disturbance is relatively slow. Aboveground dead biomass remained high 14 years after the forest was disturbed by the agricultural practices. The lowest dead biomass is reached 20 years after abandonment, and the largest values are found in mature forests. Data analysis of 80-year-old stands showed that the species composition approached that of a mature forest. Approximately 140 to 200 years was required for an abandoned farm to attain the basal area and biomass values comparable to those of a mature forest. The results of this study indicate that recovery is five to seven times longer in the Upper Rio Negro than it is in other tropical areas in South America

Um mapa temático das áreas com soja, oriundo da classificação de imagens Landsat do Estado do Rio Grande do Sul, foi utilizado como referência para auxiliar na orientação da amostragem dos pixels de treinamento e para a comparação dos resultados. Seis imagens compostas do sensor MODIS foram utilizadas para a classificação supervisionada da área de soja por meio do algoritmo de máxima verossimilhança (MAXVER adaptado ao método STRS. Os resultados foram avaliados pelo coeficiente Kappa para a totalidade da área em estudo e também para uma região de latifúndios e outra de minifúndios. O método STRS subestimou em 6,6% a área de soja para toda a região estudada, sendo que a estatística Kappa foi de 0,503. Para as regiões de latifúndios e minifúndios, a área de soja foi superestimada em 8% (Kappa=0,424 e subestimada em 43,4% (Kappa=0,358, respectivamente. As imagens MODIS, por meio do método STRS, demonstraram ter potencial para classificar a área de soja, principalmente em regiões de latifúndios.

    This report presents the chemical analyses and statistical evaluation of 62 water samples collected in the north-central part of New Mexico near Rio Ojo Caliente. Both spring and surface-water samples were taken throughout the Rio Ojo Caliente drainage basin above and a few miles below the town of La Madera. A high U concentration (15 μg/l) found in the water of the Rio Ojo Caliente near La Madera, Rio Arriba County, New Mexico, during a regional sampling-technique study in August 1975 by the senior author, was investigated further in May 1976 to determine whether stream waters could be effectively used to trace the source of a U anomaly. A detailed study of the tributaries to the Rio Ojo Caliente, involving 29 samples, was conducted during a moderate discharge period, May 1976, so that small tributaries would contain water. This study isolated Canada de la Cueva as the tributary contributing the anomalous U, so that in May 1977, an extremely low discharge period due to the 1977 drought, an additional 33 samples were taken to further define the anomalous area. 6 references, 3 figures, 6 tables

    Paulo dos Santos Pompeu

    Full Text Available Although the rio Capivari basin is recognized as an area of great importance for the ichthyofauna, it lacks virtually every basic requirement for the definition of appropriate conservation strategies, since not even its species composition is known. The objective of this work is to determine the composition and distribution of fish species in the upper rio Capivari basin, relating them to the local physical features, and to evaluate the effectiveness of proposed conservations units, delimited based on areas of native vegetation remains, on the conservation of local ichthyofauna. During 2007, 50 different watercourses were sampled with gillnets, cast nets and kick nets. A total of 1308 individuals belonging to 41 species were captured. Degree of conservation, altitude and width were the parameters that best explained fish species richness. Considering the recently proposed boundaries for potential conservation units in the region only 15 or 20 out of 41 species would be found in the State Park and Environmental Protection Area respectively. In practice, the proposed conservation units would not be effective tools for fish conservation, since it would be located in mountainous areas of high altitude, of headwaters streams and where few species are found. In such context, the conservation of specific stretches of larger rivers is critical.

    Sampling of subsurface rock may be required to detect evidence of past biological activity on Mars. The Mars Astrobiology Research and Technology Experiment (MARTE) utilized the Río Tinto region, Spain, as a Mars analog site to test dry drilling technologies specific to Mars that retrieve subsurface rock for biological analysis. This work examines the usefulness of visible-near infrared (VNIR) (450-1000 nm) point spectrometry to characterize ferric iron minerals in core material retrieved during a simulated Mars drilling mission. VNIR spectrometry can indicate the presence of aqueously precipitated ferric iron minerals and, thus, determine whether biological analysis of retrieved rock is warranted. Core spectra obtained during the mission with T1 (893-897 nm) and T2 (644-652 nm) features indicate goethite-dominated samples, while relatively lower wavelength T1 (832-880 nm) features indicate hematite. Hematite/goethite molar ratios varied from 0 to 1.4, and within the 880-898 nm range, T1 features were used to estimate hematite/goethite molar ratios. Post-mission X-ray analysis detected phyllosilicates, which indicates that examining beyond the VNIR (e.g., shortwave infrared, 1000-2500 nm) will enhance the detection of other minerals formed by aqueous processes. Despite the limited spectral range of VNIR point spectrometry utilized in the MARTE Mars drilling simulation project, ferric iron minerals could be identified in retrieved core material, and their distribution served to direct core subsampling for biological analysis.

    In the southwestern United States (US), the Rio Grande chub (Gila pandora) is state-listed as a fish species of greatest conservation need and federally listed as sensitive due to habitat alterations and competition with non-native fishes. Characterizing genetic diversity, genetic population structure, and effective number of breeders will assist with conservation efforts by providing a baseline of genetic metrics. Genetic relatedness within and among G. pandora populations throughout New Mexico was characterized using 11 microsatellite loci among 15 populations in three drainage basins (Rio Grande, Pecos, Canadian). Observed heterozygosity (HO) ranged from 0.71–0.87 and was similar to expected heterozygosity (0.75–0.87). Rio Ojo Caliente (Rio Grande) had the highest allelic richness (AR = 15.09), while Upper Rio Bonito (Pecos) had the lowest allelic richness (AR = 6.75). Genetic differentiation existed among all populations with the lowest genetic variation occurring within the Pecos drainage. STRUCTURE analysis revealed seven genetic clusters. Populations of G. pandora within the upper Rio Grande drainage (Rio Ojo Caliente, Rio Vallecitos, Rio Pueblo de Taos) had high levels of admixture with Q-values ranging from 0.30–0.50. In contrast, populations within the Pecos drainage (Pecos River and Upper Rio Bonito) had low levels of admixture (Q = 0.94 and 0.87, respectively). Estimates of effective number of breeders (N b ) varied from 6.1 (Pecos: Upper Rio Bonito) to 109.7 (Rio Grande: Rio Peñasco) indicating that populations in the Pecos drainage are at risk of extirpation. In the event that management actions are deemed necessary to preserve or increase genetic diversity of G. pandora, consideration must be given as to which populations are selected for translocation.

    Among the conceivable modern habitats to be explored for searching life on Mars are those potentially developed underground. Subsurface habitats are currently environments that, under certain physicochemical circumstances, have high thermal and hydrochemical stability [1, 2]. In planets like Mars lacking an atmospheric shield, such systems are obviously protected against radiation, which strongly alters the structure of biological macromolecules. Low porosity but fractured aquifers currently emplaced inside ancient volcano/sedimentary and hydrothermal systems act as excellent habitats [3] due to its thermal and geochemical properties. In these aquifers the temperature is controlled by a thermal balance between conduction and advection processes, which are driven by the rock composition, geological structure, water turnover of aquifers and heat generation from geothermal processes or chemical reactions [4]. Moreover, microbial communities based on chemolithotrophy can obtain energy by the oxidation of metallic ores that are currently associated to these environments. Such a community core may sustain a trophic web composed of non-autotrophic forms like heterotrophic bacteria, fungi and protozoa.

    A field prototype of an antibody array-based life-detector instrument, Signs Of LIfe Detector (SOLID2), has been tested in a Mars drilling mission simulation called MARTE (Mars Astrobiology Research and Technology Experiment). As one of the analytical instruments on the MARTE robotic drilling rig, SOLID2 performed automatic sample processing and analysis of ground core samples (0.5 g) with protein microarrays that contained 157 different antibodies. Core samples from different depths (down to 5.5 m) were analyzed, and positive reactions were obtained in antibodies raised against the Gram-negative bacterium Leptospirillum ferrooxidans, a species of the genus Acidithiobacillus (both common microorganisms in the Río Tinto area), and extracts from biofilms and other natural samples from the Río Tinto area. These positive reactions were absent when the samples were previously subjected to a high-temperature treatment, which indicates the biological origin and structural dependency of the antibody-antigen reactions. We conclude that an antibody array-based life-detector instrument like SOLID2 can detect complex biological material, and it should be considered as a potential analytical instrument for future planetary missions that search for life.

    the Rio Grande study area. The pattern in dissolved-solids concentrations along the Rio Grande is one of increasing concentration with increasing distance downstream from Elephant Butte and Caballo Reservoirs. The concentration of dissolved solids in the Rio Grande doubles (approximately 500 to 1,000 mg/L) from below Elephant Butte Reservoir to El Paso and increases by more than a factor of 5 (approximately 500 to 3,200 mg/L) from below Elephant Butte Reservoir to Fort Quitman. Marked increases in the concentration of dissolved solids commonly coincide with contributions from agricultural drains, wastewater-treatment plants, regional groundwater, and upward-flowing saline groundwater. The greatest factor, from the surface-water system, in controlling dissolved solids in the Rio Grande is the amount of water that is being transported or stored. Annual variation in streamflow is influenced primarily by climate (precipitation and evaporation) and management of Elephant Butte and Caballo Reservoirs (water storage and release cycles). Seasonal variation in streamflow within the Rio Grande study area is generally categorized generally as irrigation (March–September) and nonirrigation (October–February) seasons; with streamflow in the Rio Grande is highest during the irrigation season and lowest during the nonirrigation season. Dissolved-solids loads during the irrigation season decrease between Leasburg and Fort Quitman primarily because of irrigation diversions and losses to the underlying alluvial aquifer. Conversely, dissolved-solids loads during the nonirrigation season increase between Caballo Dam and Fort Quitman primarily because of the inflow of dissolved solids from agricultural drains, wastewater-treatment plants, and groundwater with elevated concentrations of dissolved solids. Many studies have mass-balance budgets that account for the mass of dissolved solids transported along the Rio Grande. Results from mass-balance budgets developed for dissolved solids

    Full Text Available The aim of the present study was to describe the diet of the adult cutlassfish, Trichiurus lepturus, in northern Rio de Janeiro, through stomach content analysis. The sampling included 350 specimens measuring between 100 and 163cm in total length, collected from 2004 to 2006. For each prey species, the frequency of occurrence, density and biomass, body length and weight, and Index of Relative Importance (IRI were calculated. The cannibalistic feeding behavior of the cutlassfish was also recorded. According to the IRI, the preferential prey species were the fishes T. lepturus, Pellona harroweri, Chirocentrodon bleekerianus, Lycengraulis grossidens, Peprilus paru, Chloroscombrus chrysurus, Odontognathus mucronatus, Stellifer brasiliensis and Isophisthus parvipinnis, and the crustacean Pleoticus muelleri. The cephalopods Loligo sanpaulensis and L. plei occurred occasionally in the stomach contents analyzed. The diet of T. lepturus in northern Rio de Janeiro was composed of pelagic and demersal prey species, associated with estuarine and coastal areas. The fish species and one crustacean species were the most representative items in its diet.

    Full Text Available In region of Vale do Rio Pardo, situated in Rio Grande do Sul, Brazil, the production of tobacco is an important source of income, especially for family farmers. The discussion around tobacco production in the academic researches and society’s debate involves: the problems that smoking causes in human health and the same time, the role of farmers have been developed in the productive chain. In view of this, the aim of this article was to understand the trust relation between farms and the field technicians in the Vale do Rio Pardo region and the south side area of the Rio Grande do Sul, Brazil. 142 interviews have been accomplished with families that are producing tobacco, using a semi-structured form (qualitative and quantitative questions. The Likert scale, field diaries and observations were used as search tools. When farmers have been questioned about trust in agricultural technicians (using Likert scale, the answers were similar in the three cities: the southern Rio Grande do Sul, in Dom Feliciano, confidence is 69.7%; in the Vale do Rio Pardo, Rio Pardo and Santa Cruz do Sul, respectively, confidence is 63.3% and 64.6%, according to levels between “agree” and “disagree totally”. Besides, in this context, there is direct relation between trust in the field technicians and integration of tobacco. The informal relation between farms and the field technicians has been changed by formal contracts. Nevertheless, informality was relevant, specifically because it may help to understand how the trust emerges in friendships and family relations.

    Full Text Available SUMMARY Chagas disease (CD is an endemic anthropozoonosis from Latin America of which the main means of transmission is the contact of skin lesions or mucosa with the feces of triatomine bugs infected by Trypanosoma cruzi. In this article, we describe the first acute CD case acquired by vector transmission in the Rio de Janeiro State and confirmed by parasitological, serological and PCR tests. The patient presented acute cardiomyopathy and pericardial effusion without cardiac tamponade. Together with fever and malaise, a 3 cm wide erythematous, non-pruritic, papule compatible with a "chagoma" was found on his left wrist. This case report draws attention to the possible transmission of CD by non-domiciled native vectors in non-endemic areas. Therefore, acute CD should be included in the diagnostic workout of febrile diseases and acute myopericarditis in Rio de Janeiro.

    Full Text Available O rio Cuiabá é um importante tributário do rio Paraguai, cuja bacia é de grande importância por agasalhar o Pantanal, a maior área úmida do planeta. A base econômica da bacia hidrográfica do rio Cuiabá é a produção agrícola e pecuária que, para manter elevada produtividade, requer grandes quantidades de insumos agrícolas como os pesticidas que, podem atingir diversos ambientes devido aos processos de dispersão que ocorrem após sua introdução no ambiente. Os sedimentos desempenham importante papel para a caracterização da poluição de rios devido a seu potencial de acumulação de poluentes. Este estudo objetivou avaliar a contaminação por pesticidas usados nas lavouras plantadas na bacia do rio Cuiabá, MT. Para tanto, amostras de sedimento de fundo foram coletadas mensalmente de agosto de 2011 a julho de 2012. Para a determinação dos pesticidas atrazina, cipermetrina, clorpirifós, endossulfam (α, β e seu metabólito endossulfam sulfato, lambda-cialotrina, malationa, metolacloro, metribuzim, parationa metílica, permetrina e trifuralina no sedimento utilizou-se método multirresíduo que consiste na extração sólido-líquido por agitação mecânica seguida de purificação por extração líquido-líquido e identificação e quantificação por cromatografia a gás acoplada a espectrometria de massas. Resíduos de pesticidas foram identificados em amostras coletadas em agosto e setembro de 2011 e janeiro, fevereiro, abril e julho de 2012, em concentrações variando de 5,7 a 79,3 µg kg-1 . Embora a frequência de detecção tenha sido baixa, esses resultados indicam que há potencial de transporte de pesticidas usados na bacia do rio Cuiabá e seus tributários atingindo o Pantanal.

    A água destinada ao consumo humano deve ser adequada para a manutenção da saúde e para isso não só o tratamento mas também o armazenamento da água deve ser realizado de maneira adequada. Como os reservatórios domiciliares podem atuar como fator deteriorador, realizou-se um inquérito com 74 moradores da cidade de Araraquara visando obter informaçãoes sobre o conhecimento da finalidade e os cuidados despendidos à limpeza dos reservatórios. Os resultados monstraram que 67,6% dos entrevistados conheciam a finalidade dos reservatórios e apenas 59,5% realizavam limpeza periódica. Apesar de 94,6% saberem da necessidade das limpezas 40% justificaram não fazê-las devido as dificuldades de acesso e 53,3% por outros motivos. A classe social foi estimada através de questionário padrão e os dados obtidos avaliados estatisticamente. Dos cruzamentos apenas o estado de conservação do reservatório por classe social foi significativo. Os resutados demonstram portanto que os cuidados necessários à manutenção da qualidade da água não estão sendo observados e que campanhas de informação e esclarecimento devem ser realizadas para evitar a deterioração da qualidade da água armazenada nos reservatórios domiciliares. PALAVRAS-CHAVE: Reservatório domiciliar e qualidade da água.

    2003-08-01

    O período republicano até 1930 foi marcante na história do Observatório Nacional. Diversas reformas levaram a instituição a três ministérios diferentes e mudaram a ênfase do seu trabalho. A tão aguardada mudança para uma nova sede, em São Cristóvão, em 1920, não foi suficiente para que a instituição acompanhasse o ritmo tomado pela astronomia no mundo e se firmasse como ambiente de pesquisa. Uma análise simplificada poderia caracterizar um período de produção científica insignificante, dado o distanciamento da instituição dos novos rumos da astrofísica e da rápida inovação dos instrumentos, além do pequeno volume de publicações. Era uma época em que ainda não existiam os mecanismos formais de apoio e avaliação da atividade científica. Esse trabalho procura identificar a real atividade do Observatório no conteúdo dos Relatórios Ministeriais que, ao final de cada ano, apresentava as atividades, sucessos e problemas enfrentados pela instituição. Questões como instrumental e recursos humanos necessários; entraves burocráticos e financeiros; e articulações com outros observatórios se complementaram entre si ao longo desses anos para definir o perfil institucional e alguns aspectos fundamentais para a construção da astronomia no país. É possível concluir que a ênfase em serviços geográficos e de meteorologia, ao lado da inadequação dos instrumentos e do local, quase fizeram desaparecer a pesquisa em astronomia. Porém, vale destacar a sobrevivência de alguns trabalhos, como, por exemplo, variação de latitude e observação de estrelas duplas que mantiveram importante intercâmbio com outros grupos de pesquisa, demonstrando o constante esforço dos astrônomos e das diretorias em defesa da atividade científica.

    Full Text Available The effects of an increasing downriver pollution gradient on the reproductive system of Astyanax fasciatus were investigated in the Rio dos Sinos, RS. The comparison of mean oocyte diameters, gonadal indices and gonado-somatic relationships of specimens captured in polluted areas with individuals from unpolluted reference sites revealed a significant decrease of these parameters with increasing water pollution. High loads of organic and industrial sewage are considered responsible for these effects. Condition factors showed an inverse relationship, and increased significantly in downriver polluted areas. The declining gonadal indices showed that energy was allocated to somatic growth. The results of the study recommend the use of A. fasciatus in biomonitoring essays.

E-mail: ummaia@usp.br This study aimed to assess the current status of stingless bee beekeeping (meliponiculture in the State of Rio Grande do Norte, Brazil, with the aid of structured questionnaires made during visits to beekeepers. The results were compared with a previous census made in the state and with a similar study from Australia. Meliponiculture in Rio Grande do Norte is still informal and little standardized. The activity has grown in recent years considering the mean number of nests per beekeeper. Most apiaries are formed of up to 50 colonies, usually distributed in the backyards of homes. Twelve species of stingless bees were reared in the state, and the most common was the “Jandaíra” bee (Melipona subnitida, whose honey is considered medicinal. While many beekeepers already know the importance of bees as pollinators, stingless bees are still not used for crop pollination. Compared to a recent analysis of beekeeping in Australia, meliponiculture in Brazil is more traditional, honey is the main product and the number of colonies per beekeeper is much higher. Our results highlight the need to reinforce knowledge about bees and promote specific training aimed at improving and standardizing management practices.

    2007-09-01

    Full Text Available Studies of heavy minerals in kaolin deposits from the Ipixuna Formation in the Rio Capim area (Northern Brazil showed a mature to super mature assemblage dominated by zircon and tourmaline, and subordinately rutile, kyanite and staurolite. These minerals do not change much throughout the whole section; however, each kaolin unit displays a particular signature, defined by differences in the proportions of the whole assemblage of heavy minerals, as well as of their textural characteristics. This work revealed that the lower and upper kaolin units can be definitely considered as distinct depositional sequences. A higher proportion of opaque minerals and higher zircon values characterize the lower unit. The higher volumes of anhedric, rounded to sub-rounded grains of zircon and tourmaline in the upper unit suggests that this includes grains that were undergone to a higher degree of reworking. The increased volume of unaltered staurolite and kyanite in the upper unit leads to conclude that, even considering sediment reworking, a distinct source must be invoked. The results also show that the characteristics of the heavy mineral assemblage from the intermediate unit are comparable with those from the upper unit, which suggests they might record a same stratigraphic sequence.Estudos de minerais pesados provenientes em depósitos cauliníticos da Formação Ipixuna na região do rio Capim (Brasil revelaram uma mineralogia matura a supermatura, representada dominantemente por zircão e turmalina e, subordinadamente, rutilo, cianita e estaurolita.

    Full Text Available Eucalyptus Shoot Blight in the Vale do Rio Doce (ESBVRD is an anomaly that leads to reduced growth and, in more extreme cases, to death of eucalyptus plants. Initially diagnosed in plantations in the region of the Vale do Rio Doce, in the State of Minas Gerais, Brazil, this problem has also been found in plantations in other regions of the country and even in other countries. Although the symptoms of this anomaly are well-known, its causes are not yet understood. The aim of this study was to evaluate the cause-effect relationship between accumulation of manganese (Mn in eucalyptus clones and ESBVRD. Characterization of the environment in areas of greater occurrence of this problem in regard to soil, climate and fluctuation of the water table was undertaken in eucalyptus plantations of the Celulose Nipo-brasileira S.A. (Cenibra company in the region of the Vale do Rio Doce. Plant tissues were sampled in two situations. In the first situation, diagnosis occurred in the initial phase of the anomaly in clones with differentiated tolerance to the problem; in the second situation, diagnosis was made in a single clone, considered to be sensitive, in two time periods - in the phase with the strong presence of symptoms and in the recovery phase, in areas of occurrence and in areas of escape from the problem. The most ESBVRD-sensitive clone showed much higher (4.8 times higher leaf Mn contents than more tolerant clones. In plants with the anomaly, Mn leaf contents were greater than 3,070 mg kg-1, much greater than the quantity found in those without the anomaly (734 mg kg-1. In the period in which the symptoms began to wane, there was a sharp decline in leaf Mn contents, from 2,194 to 847 mg kg-1. Manganese content in the above ground part and plant litter (44.4 g ha-1 in the area of occurrence of the anomaly was three times greater than that found in these same components (14.1 g ha-1 in the area of absence of the symptom.

    This work aimed to assessing Strongyluris sp. cysts distribution pattern in the several inner organs from pallial system of Achatina fulica Bowdich, 1822. Also we verified if there is a relationship between the mollusk size and the number of specimens from parasites collected from two touristic villages in Ilha Grande (Angra dos Reis, Rio de Janeiro state): Vila Dois Rios (VDR) and Vila do Abraão (ABR). The samples were obtained through a field work conducted bimonthly during 2007, 2008, 2010, and 2011, at both locations. Height and width were measured from shells collected, and the all specimens were classified in different classes: class 1 - biomass and a larger area of the pallial system, allowing an efficient parasite colonization. Other possible explanation could be the long exposure of the molluscs of class 3 to the parasites, which allowed a longer time to the larvae to allocate themselves.

    Full Text Available Professor Vincent Tinto opens this issue of the International Journal of the First Year in Higher Education by highlighting the importance of paying attention to students' experiences in the classroom.  With the classroom experience of students in the United States college system firmly in mind, Tinto draws attention to what he calls the "attributes of effective classrooms".  The classroom attributes he describes, such as clear expectations, timely support, feedback on assessment, engaging pedagogies and enhancing teaching skills, though drawn from the United States experience, are universal and as such are transferrable across national boundaries and applicable to higher education educators, leaders and policy makers globally. You can assess this universality by relating Tinto's criteria to your teaching environment.

    The Rio Bermudez micro-basin makes up part of the principal hydrological resource area in the Central Region of Costa Rica. For this reason a study was done to determine the availability of hydrological resources in said micro-basin to identify areas with potential water availability problems. A monthly water balance was calculated using land use, geomorphology and climate parameters. From these water balance studies, the amount of available water was calculated and classified into four categories, however, in this micro-basin, only three categories were identified: high, medium and moderate water availability. No areas were identified with low water availability, indicating availability is sufficient; however, there is increasing demand on water resources because over half of the micro-basin area is classified as having moderate water availability.

    The priority areas of intervention to support environmental management of the micro-watershed of the Rio Macho are determined from the supply of water ecosystem services, associated with human consumption of water. Socioeconomic and biophysical conditions are characterized in that micro-watershed. The state of the main variables are determined in the incidence of the supply of water ecosystem services in the micro-watershed. A zoning is realized to determine the priority areas of intervention based on the supply of water ecosystem services. Intervention guidelines are proposed in the different priority areas to improve the supply of water ecosystem services of the future. The proposals were focused on the protection of forest cover, pollution reduction plans in riverbeds and the work with communities in environmental education programs [es

    Full Text Available Justificativa e objetivos: a solicitação indiscriminada de exames complementares na avaliação pré-anestésica é comum na prática clínica e implica custos adicionais e a possibilidade de resultados falso-positivos. Os objetivos desta pesquisa foram analisar se os exames pré-operatórios em cirurgias eletivas são solicitados segundo critério clínico e avaliar os custos desnecessários para a instituição. Métodos: foram avaliadas as solicitações de exames pré-operatórios em pacientes adultos submetidos a cirurgias eletivas não cardíacas. Os exames foram solicitados pelos cirurgiões, conforme protocolo do Serviço de Anestesia. Foram avaliados dados demográficos, estado físico, comorbidades e tipo de exame complementar solicitado. Os exames feitos foram comparados com os exames indicados. O custo dos exames foi baseado na tabela Datasus. Resultados: foram avaliados 1.063 pacientes. Verificou-se que 41,9% dos exames feitos nos pacientes classificados como ASA I não estavam indicados. No grupo de risco ASA II foram feitos 442 exames (17,72% sem necessidade. Perceberam-se elevadas porcentagens na solicitação de hemograma, creatinina, coagulograma, raios X de tórax e ECG nos grupos ASA I-II. Apenas 40 (5,25% dos exames feitos no grupo ASA III não estavam indicados. Nos pacientes do grupo ASA IV, 22,5% dos exames necessários não foram feitos. Ressalta-se uma economia anual de 13% (R$1.923,13 caso os exames fossem feitos conforme o protocolo. Conclusões: os exames pré-operatórios nem sempre são solicitados de acordo com critérios clínicos, o que resulta em maiores custos para a instituição.

    Full Text Available INTRODUÇÃO: A letalidade da malária na região extra-amazônica é cerca de 80 vezes maior do que na Amazônia, que concentra 99,8% dos casos do país. Em áreas de transmissão de dengue, como o Rio de Janeiro, o atraso no diagnóstico e tratamento da malária dos pacientes com febre, provenientes de áreas endêmicas de malária, pode ser, entre outros fatores, devido à confusão entre o diagnóstico das duas doenças pelos generalistas da rede de assistência médica. Neste trabalho, apresentamos as consequências do atraso diagnóstico em três pacientes com malária por Plasmodium falciparum; P. malariae e P. vivax, que, após o périplo habitual para tratamento de dengue, procuraram a nossa instituição onde foram corretamente diagnosticados e submetidos aos tratamentos adequados. MÉTODOS: Descrição de três casos de malária diagnosticada tardiamente e encaminhados ao IPEC/ FIOCRUZ, entre os anos de 2007 e 2008. RESULTADOS: uma brasileira proveniente de Moçambique, primo-infectada por P. falciparum, com malária diagnosticada após 6 dias do início da febre, morreu com malária cerebral e choque. Outro paciente com malária por P. malariae teve um curso grave e prolongado, mas ficou curado após o tratamento específico. A terceira paciente diagnosticada tardiamente apresentou malária por P. vivax adquirida na região de Mata Atlântica no Estado do Rio. CONCLUSÕES: Os profissionais de saúde do Rio devem ser treinados para aperfeiçoar a vigilância e o tratamento oportuno da malária e evitar desfechos mórbidos e fatais. Sugere-se que uma investigação de focos de malária autóctone em áreas de mata no estado seja realizada.INTRODUCTION: The mortality of malaria in the extra-Amazon region is about 80 times higher than in the Amazon region, where malaria is concentrated (99.8% of cases.

    Highlights: • A use case example of RIO/FlexRIO design methodology is described. • Ion source device is controlled and monitored by means EPICS IOCs. • NIRIO EPICS device support demonstrates that is able to manage RIO devices. • Easy and fast deployment is possible using RIO/FlexRIO design methodology using NIRIO-EDS. • RIO/FlexRIO technology and EPICS are a good combination for support large scale experiments in fusion environments. - Abstract: Experimental Physics and Industrial Control System (EPICS) is a software tool that during last years has become relevant as a main framework to deploy distributed control systems in large scientific environments. At the moment, ESS Bilbao uses this middleware to perform the control of their Ion Source Hydrogen Positive (ISHP) project. The implementation of the control system was based on: PXI Real Time controllers using the LabVIEW-RT and LabVIEW-EPICS tools; and RIO devices based on Field-Programmable Gate Array (FPGA) technology. Intended to provide a full compliant EPICS IOCs for RIO devices and to avoid additional efforts on the system maintainability, a migration of the current system to a derivative Red Hat Linux (CentOS) environment has been conducted. This paper presents a real application case study for using the NIRIO EPICS device support (NIRIO-EDS) to give support to the ISHP. Although RIO FPGA configurations are particular solutions for ISHP performance, the NIRIO-EDS has permitted the control and monitoring of devices by applying a well-defined design methodology into the previous FPGA configuration for RIO/FlexRIO devices. This methodology has permitted a fast and easy deployment for the new robust, scalable and maintainable software to support RIO devices into the ISHP control architecture.

    Full Text Available The atypical kinase Rio1 is widespread in many organisms, ranging from Archaebacteria to humans, and is an essential factor in ribosome biogenesis. Little is known about the protein substrates of the enzyme and small-molecule inhibitors of the kinase. Protein kinase CK2 was the first interaction partner of Rio1, identified in yeast cells. The enzyme from various sources undergoes CK2-mediated phosphorylation at several sites and this modification regulates the activity of Rio1. The aim of this review is to present studies of the relationship between the two different kinases, with respect to CK2-mediated phosphorylation of Rio1, regulation of Rio1 activity, and similar susceptibility of the kinases to benzimidazole inhibitors.

    The intense flow of fossil fuels in the inland waters of Patos Lagoon (LP) - Rio Grande do Sul, justifies the importance of preventive actions to claims by oil and derivatives within the lagoon. The mapping and classification of coastline environmental sensitivity for oil spills (Cartas SAO) is fundamental tool for this type of action. Therefore, since 2001, the Laboratory of Geological Oceanography (LOG) of Federal University of Rio Grande (FURG) has developed the mapping SAO for the LP. In this work, through review of raw data from the database of LOG, and taking into account the methodology proposed by the Ministry of Environment (MMA, 2004), gave up a strategic projection of standardized environmental sensitivity of the oil spill to Patos Lagoon. This new account also enable a better understanding of the lagoon ecosystem, enables comparisons between its different areas, facilitating the planning and decision-making, allowing the management for faster action-in response. Like, highlights the regions of the estuary of the LP, the delta of the Camaqua River and Casamento Lagoon as the areas of greater sensitivity to environmental spillage of oil from Patos Lagoon.

    Field-scale water use maps derived from evapotranspiration (ET) can characterize water use patterns and the impacts of water management decisions. This project generated historical (1984-2015) Landsat-based ET maps for the entire Upper Rio Grande basin which makes this one of the largest regions in the United States with remotely sensed historical ET at Landsat resolution. More than 10,000 Landsat images spanning 32 years were processed using the Operational Simplified Surface Energy Balance (SSEBop) model which integrates weather data and remotely sensed images to estimate monthly and annual ET. Time-series analysis focused on three water-intensive study areas within the basin: the San Luis Valley in Colorado, irrigated fields along the Rio Grande River near Albuquerque, NM, and irrigated fields near Las Cruces, NM. Preliminary analysis suggests land use changes result in declining water use in irrigated areas of the basin which corresponds with increases in land surface temperatures. Time-series analysis of water use patterns at multiple temporal and spatial scales demonstrates the impact of water management decisions on the availability of water in the basin. Comparisons with cropland data from the USDA (NASS CDL) demonstrate how water use for particular crop types changes over time in response to land use changes and shifts in water management. This study illustrates a useful application of "Big Data" earth observation science for quantifying impacts of climate and land use changes on water availability within the United States as well as applications in planning water resource allocation, managing water rights, and sustaining agricultural production in the Upper Rio Grande basin.

    Full Text Available ABSTRACT: At the end of the 20th and early 21st century, agricultural systems incorporated definitively a new mission: to generate goods for a world population that continues to grow and whose way of life demand food with low environmental impact. Soybean is the main raw material for the production of biodiesel in Brazil, accountably responsible for 82.4% of the total produced between 2006 and 2013. The Brazilian state of Rio Grande do Sul (RS, which is formed by the Pampa and the Atlantic forest biomes, was responsible for 35.7% of the country's biodiesel production in the referred period. The aim of this paper was to verify the impact of the increased area of soybean cultivation in land use in Rio Grande do Sul State, in the period between 1990 and 2015, considering separately its two biomes (Pampa and Atlantic Forest original areas, using both census dataset and satellite images. We used the period from 1990 to 2000 as before commodity rising price (BCRP and the period from 2000 to 2013 as commodity rising price (CRP. The 505,162 ha from Atlantic Forest biome and 1,192,115ha from Pampa biome were added to soybean production in the CRP period. In the Atlantic Forest, this enlargement occurred in the border of the main production area, while in Pampa biome conversion of natural grassland to crop land was the main reason for the large increment in the cultivated area.

    The Secretary-General of the UN Conference on Environment and Development notes that after the Earth Summit in Rio de Janeiro discussions about the environment and development will differ from those prior to the Summit. These discussions must now incorporate problems of developing countries, poverty, inequalities, flow of resources to developing countries, and terms of trade. The Rio Declaration on Environment and Development consists of important tenets, but it must evolve into an Earth Charter to be endorsed on the 50th anniversary of the UN in 1965. The Summit's Plan of Action, Agenda 21, must also continue to evolve and, despite its shortcomings, is the most extensive and, if implemented, most effective international action ever approved by the international community. Financing the Agenda 21 initiatives remains to be decided. New possible sources of funding must be based n the polluter pays principle and may include new taxes, user charges, emission permits, and citizen funding. Even though the most serious problem in the 1990s is stabilization of atmospheric gases, the Rio agreement does not include targets or timetables. Governments must take united action immediately to reduce carbon dioxide emissions by at least 60%. 1 nation has not yet approved the convention on biological diversity. Governments also need to move forward on conventions on decertification and deforestation. They need to incorporate the global objectives of Agenda 21 into their own national policies and practices. This must also be done at the global, regional, organizational, local, and individual levels. The global community must also begin technology capacity building. The participatory process should also include nongovernmental organizations. Population growth must also slow dramatically to achieve sustainable development. The various participatory levels must consider elimination of poverty.

    2005-12-01

    Full Text Available ANTECEDENTES: O Conselho Nacional de Previdência Social, por meio da Resolução No. 1.236 de 28/4/2004, aprovou uma nova metodologia para definição do valor das alíquotas de contribuição devidas por empresas para o financiamento de benefícios previdenciários relacionados aos riscos do trabalho. Esta metodologia baseia-se em um indicador denominado de Fator Acidentário Previdenciário, FAP, construído a partir do risco epidemiológico, estimado para cada ramo de atividade econômica. Como parte da sua estratégia de validação, o Ministério da Previdência Social decidiu pela avaliação da sua consistência epidemiológica. OBJETIVOS: Nesse estudo analisaram-se os propósitos, as fontes de informação, a natureza das medidas epidemiológicas empregadas e a metodologia da construção desse indicador, identificando-se as suas vantagens e limitações, aplicabilidade e impactos potenciais futuros. MÉTODOS: Análise documental da Resolução No. 1236 e do documento anexo. RESULTADOS: O FAP avança ao se pautar por critérios científicos transparentes que poderão permitir a redução das alíquotas quando houver efetiva melhoria das condições de trabalho, e conseqüentemente, da morbimortalidade entre trabalhadores. Supera as dificuldades relacionadas à definição e registro do nexo causal das doenças do trabalho ao considerá-las em sua totalidade, não se restringido às ocupacionais. Como prevê a redução de alíquotas com a melhoria das condições de saúde dos trabalhadores poderá contribuir para uma mais efetiva atuação dos empregadores na prevenção. CONCLUSÕES: É necessário o acompanhamento contínuo e sistemático da aplicação do FAP, com ampla participação da sociedade, revisando-o e ajustando-o aos diferentes cenários econômicos, sociais e de saúde do País, atentando-se para o seu impacto sobre a arrecadação e contas da Previdência Social.BACKGROUND: The Brazilian National Social Insurance

    Full Text Available O trabalho voluntário é a força das organizações da sociedade civil. Existem diferenças entre o trabalho voluntário e o formal, como a remuneração e o tempo destinado ao desempenho das atividades. Ao contrário de trabalhadores formais, voluntários não recebem pagamento para o desempenho de funções. Logo, teorias motivacionais desenvolvidas numa perspectiva de trabalho formal não devem ser aplicadas a este grupo. Esse estudo identificou motivações apresentadas pelos candidatos a voluntários e atuais voluntários da Fundação Cidade Viva em João Pessoa. Quanto aos resultados, verifica-se predominância do perfil altruísta em ambas as fases utilizadas do modelo. Ainda, o perfil egoísta, foi o menos apresentado pelos respondentes da pesquisa. Outros resultados, relativos ao desligamento da atividade voluntária na Fundação, foram bastante inconclusivos.

    Guanabara Bay is the second largest bay in the coast of Brazil, with an area of 384 km2. In its surroundings live circa 16 million inhabitants, out of which 6 million live in Rio de Janeiro city, one of the largest cities of the country, and the host of the 2016 Olympic Games. Anthropogenic interference in Guanabara Bay area started early in the XVI century, but environmental impacts escalated from 1930, when this region underwent an industrialization process. Herein we present an overview of the current environmental and sanitary conditions of Guanabara Bay, a consequence of all these decades of impacts. We will focus on microbial communities, how they may affect higher trophic levels of the aquatic community and also human health. The anthropogenic impacts in the bay are flagged by heavy eutrophication and by the emergence of pathogenic microorganisms that are either carried by domestic and/or hospital waste (e.g., virus, KPC-producing bacteria, and fecal coliforms), or that proliferate in such conditions (e.g., vibrios). Antibiotic resistance genes are commonly found in metagenomes of Guanabara Bay planktonic microorganisms. Furthermore, eutrophication results in recurrent algal blooms, with signs of a shift toward flagellated, mixotrophic groups, including several potentially harmful species. A recent large-scale fish kill episode, and a long trend decrease in fish stocks also reflects the bay’s degraded water quality. Although pollution of Guanabara Bay is not a recent problem, the hosting of the 2016 Olympic Games propelled the government to launch a series of plans to restore the bay’s water quality. If all plans are fully implemented, the restoration of Guanabara Bay and its shores may be one of the best legacies of the Olympic Games in Rio de Janeiro. PMID:26635734

    2011-12-01

    Introduction Due to high water demand, the scarcity of water, and the complexity of water allocation, environmental flows have not been considered as an integral part of the water management in the Rio Grande/Rio Bravo transboundary basin. The Big Bend reach is located between the cities of Presidio/Ojinaga to Amistad international reservoir, along the main stream (Fig. 1). Important environmental habitats such as the Big Bend National and State Park in the U.S., the Maderas del Carmen, Cañon de Santa Elena and Ocampo natural reserved areas in Mexico are ecologically threatened because of the lack of environmental water management policies. Several efforts have been undertaken by scientists, government agencies and NGOs to determine the environmental flows for this reach and water management policies that can provide these flows. Objective The objective of this research is to describe a water management policy that can conciliate environmental and human water uses in the Big Bend region. In other words, define a policy that can provide environmental flows without harming water supply for stakeholders or increasing flood risk, within legal and physical constraints of the system. Methodology First, the system was characterized identifying water users, hydraulic infrastructure, and water allocation according to state, federal and international regulations. Second, a hydrograph for environmental flows was proposed that mimics the hydrologic characteristics of the prior dam alteration. Third, a water planning model was constructed to evaluate alternative policies. Fourth, the water management is proposed to provide environmental restoration flows from Luis L. Leon reservoir. This policy considers mechanisms that reduce flooding and drought risks, while meting national and international water regulations. Results Three types of natural flow regimes are considered: (1) median flows aimed to provide the base flow in the region, (2) high flows to provide transversal

    Full Text Available Aplicação da tecnologia na agricultura dentro do sistema de produção é realidade principalmente com a abertura de mercados através da globalização. Em diversas áreas da indústria moderna, o calcário é utilizado como corretor da acidez do solo. A calagem é uma prática barata, porém ainda é negligenciada quanto ao seu uso, na adoção da técnica, à definição das doses e às formas de aplicação. A briquetagem consiste na aglomeração de partículas finas através de pressão, auxiliada ou não por aglomerantes, permitindo obtenção de produtos compactados, com forma, tamanho e parâmetros mecânicos adequados. A redução de volume do material, além dos benefícios tecnológicos, permite que materiais finos possam ser transportados e armazenados de forma mais econômica. A recente preocupação ambiental, resultando em leis mais rígidas, além da necessidade de aproveitar economicamente os resíduos e as partículas finas geradas no beneficiamento de minérios fez com que a briquetagem voltasse a ser uma importante alternativa para aglomerar valor econômico. O objetivo deste trabalho foi aglomerar finos de calcário através da briquetagem (92% abaixo de 500# ou 25 µm gerados no processamento do mesmo, variando as dosagens de água (utilizada como agente aglomerante de 0; 5; 7,5; 10; 12,5 e 15%. O calcário, originário de Lagamar (MG, foi classificado quimicamente como dolomítico tipo D. Os briquetes foram submetidos a testes de queda a 30, 60, 90, 120 e 150 cm de altura. Os melhores resultados encontrados para ensaios de queda foram obtidos com 7,5% de umidade, com médias de 21 quedas para 30 cm e 10 quedas para 60 cm de altura. Tais resultados apresentaram-se favoráveis quando comparados à literatura, a qual cita que para briquetes sem cura, considera-se 3 quedas a 0,3 m como valor razoável.

    The waterway transportation sector, despite its problems and bottlenecks, is continually seeking alternatives to improve its operations. With goals of increased efficiency, safety and cost reduction, the sector is modernizing and acquiring new technology. The Dynamic Position control system for a large barge convoy is one of the new technology highlights. This innovation may make development in the Brazilian waterway transportation sector feasible by permitting navigational safety and greater flexibility in transport and distribution not only for mined products but for petroleum and its derivatives. This paper presents the development process of The Dynamic Position control system for a large barge convoy in the Parana-Paraguay River, for Rio Tinto Mining Company. The hydrodynamics effects in a river are quite different than those of the traditional offshore environment. The degree of difficulty involved in solving this problem is highly dependent on a ship's characteristics, which can be analyzed in function of their hydrodynamic coefficients. Model tests in towing tanks were made to adjust the hydrodynamic coefficients and characteristics of the thrusters. The choice of the 'backstepping' control law and observer (state estimator) presented in this paper is a result of these particular conditions. The authors point out the advantage of using this technique, since all the properties of the coefficients of the hull, propeller(s) and thruster(s) have already been tested and tuned and are able to make a reliable set-up that optimizes navigation in restricted waterways.

    Full Text Available http://dx.doi.org/10.5902/198050987548The floristic survey of tree species was performed in a ‘Restinga’ forest, municipality of Pelotas, RioGrande do sul State, Brazil. The area studied is known as ‘Mata da Praia do Totó’(‘Totó’ beach forest,and comprises a remnant formed by a sandy and turf ‘Restinga’ forest. A total 65 native species weresampled comprising 51 genera distributed in 34 families. The family with the greatest number of specieswasMyrtaceae, with ten species, followed bySalicaceaeandRubiaceae.The most representative generawereMyrsineandEugenia,respectivelly sampled with four and three species. The analysis of similaritysampled that the sandy forest is floristically related to riparian and hillside forests and the forest peat isrelated to other forests located in areas of permanent water saturation of soil. Species richness of the siteis high for ‘Restinga’ forests in Rio Grande do Sul state, probably due to the influence of forests located inSerra dos Tapes and by diversity of the environments that make up the study area.

    Shear wave splitting was measured across the eastern flank of the Rio Grande Rift (RGR) to investigate mechanisms of upper mantle anisotropy. Earthquakes recorded at epicentral distances of 90°-130° from EarthScope Transportable Array (TA) and SIEDCAR (SC) broadband seismic stations were examined comprehensively, via the Matlab program "Splitlab", to determine whether SKS and SKKS phases indicated anisotropic properties. Splitlab allows waveforms to be rotated, filtered, and windowed interactively and splitting measurements are made on a user-specified waveform segment via three independent methods simultaneously. To improve signal-to-noise and improve reliability, we stacked the error surfaces that resulted from grid searches in the measurements for each station location. Fast polarization directions near the Rio Grande Rift tend to be sub-parallel to the RGR but then change to angles that are consistent with North America's average plate motion, to the east. The surface erosional depression of the Pecos Valley coincides with fast polarization directions that are aligned in a more northerly direction than their neighbors, whereas the topographic high to the east coincides with an easterly change of the fast axis.The area above a mantle high velocity anomaly discovered separately via seismic tomography which may indicate thickened lithosphere, corresponds to unusually large delay times and fast polarization directions that are more closely aligned to a north-south orientation. The area of southeastern New Mexico that falls between the mantle fast anomaly and the Great Plains craton displays dramatically smaller delay times, as well as changes in fast axis directions toward the northeast. Changes in fast axis directions may indicate flow around the mantle anomaly; small delay times could indicate vertical or attenuated flow.

    Spatial and temporal patterns of rainfall were identified over the state of Rio de Janeiro, southeast Brazil. The proximity to the coast and the complex topography create great diversity of rainfall over space and time. The dataset consisted of time series (1967-2013) of monthly rainfall over 100 meteorological stations. Clustering analysis made it possible to divide the stations into six groups (G1, G2, G3, G4, G5 and G6) with similar rainfall spatio-temporal patterns. A linear regression model was applied to a time series and a reference. The reference series was calculated from the average rainfall within a group, using nearby stations with higher correlation (Pearson). Based on t-test ( p River (G5) and the metropolitan area of the city of Rio de Janeiro (G6). The driest months in all regions were June, July and August, while November, December and January were the rainiest months. Sharp transitions occurred when considering monthly accumulated rainfall: from January to February, and from February to March, likely associated with episodes of "veranicos", i.e., periods of 4-15 days of duration with no rainfall.

    Full Text Available In addition to the structural reforms that inaugurated elements in the public management of the State Department of Education of Rio de Janeiro (SEEDUC, expressed through goals established in its strategic planning, was also presented the Integrated School Management (GIDE, a system of management that covers strategic, political and managerial aspects of the educational area with focus on results. According to SEEDUC, through the implementation of GIDE each school unit would have a diagnosis of their situation and could give priority to the causes of the problems, helping the state to raise its results in the Index of Development of Basic Education (IDEB. In this sense, we observe the close link between GIDE and target culture, which ultimately leads to the elevation of IDEB. Under careful analysis it is possible to identify that the emphasis on managerial aspects is associated with performativity. Thus, the present text intends to present the proposal of GIDE, to relate it to the managerial context of the educational policy of Rio de Janeiro, and to reflect on the implications of the introduction of a new model of educational management in the State.

    Full Text Available The aim of this study was to analyse the infection dynamics ofAngiostrongylus cantonensisin its possible intermediate hosts over two years in an urban area in the state of Rio de Janeiro where the presence ofA. cantonensis had been previously recorded in molluscs. Four of the seven mollusc species found in the study were exotic.Bradybaena similariswas the most abundant, followed byAchatina fulica, Streptaxissp., Subulina octona, Bulimulus tenuissimus, Sarasinula linguaeformisand Leptinaria unilamellata. Only A. fulicaand B. similariswere parasitised by A. cantonensis and both presented co-infection with other helminths. The prevalence of A. cantonensisin A. fulicawas more than 50% throughout the study. There was an inverse correlation between the population size ofA. fulicaand the prevalence of A. cantonensisand abundance of the latter was negatively related to rainfall. The overall prevalence of A. cantonensisin B. similariswas 24.6%. A. fulicawas the most important intermediary host of A. cantonensisin the studied area andB. similariswas secondary in importance for A. cantonensistransmission dynamics.

    The Albuquerque area of New Mexico has two principal sources of water: (1) groundwater from the Santa Fe Group aquifer system, and (2) surface water from the Rio Grande. From 1960 to 2002, pumping from the Santa Fe Group aquifer system caused groundwater levels to decline more than 120 feet while water-level declines along the Rio Grande in Albuquerque were generally less than 40 feet. These differences in water-level declines in the Albuquerque area have resulted in a great deal of interest in quantifying the river-aquifer interaction associated with the Rio Grande.In 2003, the U.S. Geological Survey, in cooperation with the Bureau of Reclamation, acting as fiscal agent for the Middle Rio Grande Endangered Species Collaborative Program, and the U.S. Army Corps of Engineers, began a study to characterize the hydrogeology of the Rio Grande inner valley alluvial aquifer in the Albuquerque area of New Mexico. The study provides hydrologic data in order to enhance the understanding of rates of water leakage from the Rio Grande to the alluvial aquifer, groundwater flow through the aquifer, and discharge of water from the aquifer to riverside drains. The study area extends about 20 miles along the Rio Grande in the Albuquerque area. Piezometers and surface-water gages were installed in paired transects at eight locations. Nested piezometers, completed at various depths in the alluvial aquifer, and surface-water gages, installed in the Rio Grande and riverside drains, were instrumented with pressure transducers. Water-level and water-temperature data were collected from 2009 to 2010.Water levels from the piezometers indicated that groundwater movement was usually away from the river towards the riverside drains. Annual mean horizontal groundwater gradients in the inner valley alluvial aquifer ranged from 0.0024 (I-25 East) to 0.0144 (Pajarito East). The median hydraulic conductivity values of the inner valley alluvial aquifer, determined from slug tests, ranged from 30

    Full Text Available A study of polychlorinated dibenzo-p-dioxins (PCDDs, polychlorinated dibenzofurans (PCDFs and polychlorinated biphenyls (dl-PCBs was conducted in a pooled sample of breast milk from 27 primiparous mothers living in 12 locations in the meso-region industrial area of southern Rio de Janeiro, Brazil, between August 2012 and July 2013. Questionnaires with questions regarding food habits, social and economic conditions and places of dwelling were applied. Milk was collected between four and six weeks after delivery from mothers were breast-feeding only one infant. The toxic equivalency (TEQ of PCDD/Fs, and dl-PCBs were 10.6, 4.77, 6.96 TEQ pg/g, respectively. The understanding and identification of pollution sources may be helpful for applying better counter measures against breast milk dioxin contamination. It is important for pregnant women to have a diet that is as free as possible from chemical contaminants. Further research must be undertaken in the context of epidemiological investigations to more accurately assess the effects of these compounds. The background contamination by PCDD/Fs, and dl-PCBs in mothers living at industrial area in Rio de Janeiro is lower than that generally found in industrialized countries.

    This study described the sociodemographic profile and professional qualifications of pediatric intensive care physicians in the State of Rio de Janeiro (RJ), southeastern Brazil. This investigation was an observational, cross-sectional and descriptive study that was conducted in neonatal, pediatric and mixed intensive care units in the State of Rio de Janeiro. Physicians working in the participating intensive care units voluntarily completed a semistructured and anonymous questionnaire. Questionnaires that were not returned within 30 days were considered lost, and questionnaires with less than 75% questions completed were excluded. The differences in neonatal and pediatric intensive care physicians' medical training were compared using the Chi-squared test with a 5% significance level. A total of 410 physicians were included in this study: 84% female, 48% between 30 and 39 years old and 45% with monthly incomes between US $1,700 to 2,700. Forty percent of these physicians worked exclusively in this specialty, and 72% worked in more than one intensive care unit. Only 50% of the participants had received specific training (either medical residency or specialization) in neonatology, and only 33% were board-certified specialists in this area. Only 27% of the physicians had received specific training in pediatric intensive care medicine, and only 17% were board-certified specialists (p professional activity; 49% were dissatisfied due to working conditions, 23% due to low incomes and 18% due to training-related issues. These results suggested that the medical qualifications of neonatal and pediatric intensive care physicians in the State of Rio de Janeiro, Brazil are inadequate, especially in pediatric intensive care medicine. A high level of dissatisfaction was reported, which may jeopardize the quality of medical assistance that is provided by these professionals.

    Over 50 million cubic meters of mining tailings were released in the Rio Doce basin after the collapse of the Fundão dam (Samarco) in November 2015. Predicting significant impacts on the Rio Doce estuary, we sampled sediments to investigate short-term impacts on the benthic assemblages and trace metal accumulation on estuarine sediments. With the arrival of the tailing plumes in the estuary, we detected a predominance of clay particles and increased trace metal concentrations of up to 5 times in some areas. The rapid sedimentation after the impact also impacted estuarine macrofaunal assemblages through loss surface-dwelling taxa. As expected, the impacts on benthic assemblages observed up to 3days after the arrival of tailings were not clearly associated with trace metal concentrations, but long-term effects need to be studied. We recommend that the high spatial variability within the estuary be considered in future impact assessment studies. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The Rio Salado River Basin in Argentina is an economically important region that generates 25-30 percent of Argentina's grain and meat production. Between 2000-2011, floods in the basin caused nearly US$4.5 billion in losses and affected 5.5 million people. With the goal of developing cost-efficient flood monitoring and prediction capabilities in the Rio Salado Basin to support decision making, Cloud to Street is developing satellite based analytics to cover information gaps and improve monitoring capacity. This talk will showcase the Flood Risk Dashboard developed by Cloud to Street to support monitoring and decision-making at the level of provincial and national water management agencies in the Rio Salado Watershed. The Dashboard is based on analyzing thousands of MODIS, Landsat, and Sentinel scenes in Google Earth Engine to reconstruct the spatial history of flooding in the basin. The tool, iteratively designed with the end-user, shows a history of floodable areas with specific return times, exposed land uses and population, precipitation hyetographs, and spatial and temporal flood trends in the basin. These trends are used to understand both the impact of past flood mitigation investments (i.e. wetland reconstruction) and identify shifting flood risks. Based on this experience, we will also describe best practices on making remote sensing "flood dashboards" for water agencies.

    Full Text Available OBJECTIVE To analyze the spatial distribution of risk for tuberculosis and its socioeconomic determinants in the city of Rio de Janeiro, Brazil.METHODS An ecological study on the association between the mean incidence rate of tuberculosis from 2004 to 2006 and socioeconomic indicators of the Censo Demográfico (Demographic Census of 2000. The unit of analysis was the home district registered in the Sistema de Informação de Agravos de Notificação (Notifiable Diseases Information System of Rio de Janeiro, Southeastern Brazil. The rates were standardized by sex and age group, and smoothed by the empirical Bayes method. Spatial autocorrelation was evaluated by Moran’s I. Multiple linear regression models were studied and the appropriateness of incorporating the spatial component in modeling was evaluated.RESULTS We observed a higher risk of the disease in some neighborhoods of the port and north regions, as well as a high incidence in the slums of Rocinha and Vidigal, in the south region, and Cidade de Deus, in the west. The final model identified a positive association for the variables: percentage of permanent private households in which the head of the house earns three to five minimum wages; percentage of individual residents in the neighborhood; and percentage of people living in homes with more than two people per bedroom.CONCLUSIONS The spatial analysis identified areas of risk of tuberculosis incidence in the neighborhoods of the city of Rio de Janeiro and also found spatial dependence for the incidence of tuberculosis and some socioeconomic variables. However, the inclusion of the space component in the final model was not required during the modeling process.

    Sporotrichosis is caused by species of the genus Sporothrix. From 1998 to 2015, 4,703 cats were diagnosed at the Fundação Oswaldo Cruz (Fiocruz), Rio de Janeiro, Brazil. Even after the description of the Sporothrix species, the characterisation of feline isolates is not performed routinely. To characterise the clinical isolates from cats at the species level and correlate them with the clinical and epidemiological characteristics of the cats. Forty seven Sporothrix spp. isolates from cats assisted at Fiocruz from 2010 to 2011 were included. Medical records were consulted to obtain the clinical and epidemiological data. The isolates were identified through their morphological and physiological characteristics. T3B polymerase chain reaction (PCR) fingerprinting was used for molecular identification of the species. In phenotypic tests, 34 isolates were characterised as S. brasiliensis, one as S. schenckii and 12 as Sporothrix spp. PCR identified all isolates as S. brasiliensis. S. brasiliensis is the only etiological agent of feline sporotrichosis in Rio de Janeiro to date. None association was found between the isolates and the clinical and epidemiological data. In addition, we strongly recommend the use of molecular techniques for the identification of isolates of Sporothrix spp.

    Updated age assignments and new collections of molluscan fossils from lower Cenomanian through upper Campanian strata in Texas permit a much refined biostratigraphic correlation with the rocks of New Mexico and the Western Interior. Generic names of many Late Cretaceous ammonites and inoceramid bivalves from Texas are updated to permit this correlation. Strata correlated in the west-to-east transect include the lower Cenomanian Beartooth Quartzite and Sarten Sandstone of southwest New Mexico, and the Eagle Mountains Formation, Del Rio Clay, Buda Limestone, and. basal beds of the Chispa Summit, Ojinaga, and Boquillas Formations of the Texas-Mexico border area. Middle Cenomanian strata are lacking in southwestern New Mexico but are present in the lower parts of the Chispa Summit and Boquillas Formations in southwest Texas. Upper Cenomanian and lower Turonian rocks are present at many localities in New Mexico and Texas in the Mancos Shale and Chispa Summit, Ojinaga, and Boquillas Formations. Middle Turonian and younger rocks seem to be entirely nonmarine in southwestern New Mexico, but they are marine in the Rio Grande area in the Chispa. Summit, Ojinaga, and Boquillas Formations. The upper part of the Chispa Summit and Boquillas contain late Turonian fossils. Rocks of Coniacian and Santonian age are present high in the Chispa Summit, Ojinaga, and Boquillas Formations, and in the lower part of the Austin. The San Carlos, Aguja, Pen, and Austin Formations contain fossils of Campanian age. Fossils representing at least 38 Upper Cretaceous ammonite zones are present along the transect. Collections made in recent years in southwestern New Mexico and at Sierra de Cristo Rey just west of downtown El Paso, Texas, have been well treated and do not need revision. Taxonomic names and zonations published in the pre-1970 literature on the Rio Grande area of Texas have been updated. New fossil collections from the Big Bend National Park, Texas, allow for a much refined correlation

    O sistema urinário é uma das quatro vias de excreção existentes no corpo humano. A sua exposição a factores exteriores e/ou interiores torna-o sensível a diversas infecções, pelo que, actualmente, em termos de quadro clínico. as patologias relacionadas com as infecções do tracto urinário (ITU), nomeadamente, a uretrite, cistite, síndroma uretral agudo e pielonefrite, são bastantes comuns.

  10. Comparison of total Hg results in sediment samples from Rio Grande reservoir determine by NAA and CV AAS

    The Rio Grande reservoir is located in the Metropolitan area of Sao Paulo and it is used for recreation purposes and as source water for drinking water production. During the last decades has been detected mercury contamination in the sediments of this reservoir, mainly in the eastern part, near the main affluent of the reservoir, in the Rio Grande da Serra and Ribeirao Pires counties. In the present study bottom sediment samples were collected in four different sites into four sampling campaigns during the period of September 2008 to January 2010. The samples were dried at room temperature, ground and passed through a 2 mm sieve. Total Hg determination in the sediment samples was carried out by two different analytical techniques: neutron activation analysis (NAA) and cold vapor atomic absorption spectrometry (CV AAS). The methodology validation, in terms of precision and accuracy, was performed by reference materials, and presented a recovery of 83 to 108%. The total Hg results obtained by both analytical techniques ranged from 3 to 71 mg kg-1 and were considered similar by statistical analysis, even though NAA technique furnishes the total concentration while CV AAS using the 3015 digestion procedure characterizes only the bioavailable Hg. These results confirm that both analytical techniques were suitable to detect the Hg concentration levels in the Rio Grande sediments studied. The Hg levels in the sediment of the Rio Grande reservoir confirm the anthropogenic origin for this element in this ecosystem. (author)

    Urbanization is an area of growing interest in assessing the impact of human activities on water resources in arid regions. Remote sensing techniques provide an opportunity to analyze land cover change over time, and are useful in monitoring areas undergoing rapid urban growth. This case study for the water-scarce Upper Rio Grande River Basin uses a supervised classification algorithm to quantify the rate and evaluate the pattern of urban sprawl. A focus is made on the fast growing El-Paso-Juarez metropolitan area on the US-Mexico border and the City of Las Cruces in New Mexico, areas where environmental challenges and loss of agricultural and native land to urban development are major concerns. Preliminary results show that the land cover is dominantly native with some significant agriculture along the Rio Grande River valley. Urban development across the whole study area expanded from just under 3 percent in 1990, to more than 11 percent in 2015. The urban expansion is occurring mainly around the major urban areas of El Paso, Ciudad Juarez, and Las Cruces, although there is visible growth of smaller urban settlements scattered along the Rio Grande River valley during the same analysis period. The proportion of native land cover fluctuates slightly depending on how much land is under crops each analysis year, but there is a decreasing agricultural land cover trend suggesting that land from this sector is being lost to urban development. This analysis can be useful in planning to protect the environment, preparing for growth in infrastructure such as schools, increased traffic demands, and monitoring availability of resources such as groundwater as the urban population grows.

    Full Text Available This study represents one of the first contributions to the knowledge on the quantitative fidelity of the recent freshwater molluscan assemblages in subtropical rivers. Thanatocoenoses and biocoenoses were studied in straight and meandering to braided sectors, in the middle course of the Touro Passo River, a fourth-order tributary of the Uruguay River, located in the westernmost part of the State of Rio Grande do Sul. Samplings were carried out through quadrats of 5 m², five in each sector. A total area of 50 m² was sampled. Samplings were also made in a lentic environment (abandoned meander, with intermittent communication with the Touro Passo River, aiming to record out-of-habitat shell transportation from the lentic communities to the main river channel. The results show that, despite the frequent oscillation of the water level, the biocoenosis of the Touro Passo River shows high ecological fidelity and undergoes little influence from the lentic vicinal environments. The taxonomic composition and some features of the structure of communities, especially the dominant species, also reflect some ecological differences between the two main sectors sampled, such as the complexity of habitats in the meandering-sector. Regarding the quantitative fidelity, 60% of the species found alive were also found dead and 47.3% of the species found dead were also found alive, at river-scale. However, 72% of the dead individuals belong to species also found alive. This value might be related with the good rank order correlation obtained for live/dead assemblages. Consequently, the dominant species of the thanatocoenoses could be used to infer the ecological attributes of the biocoenoses. The values of all the indexes analyzed were very variable in small-scale samplings (quadrat, but were more similar to others registered in previous studies, when they were analyzed in a station and river scale.O presente estudo teve como objetivo apresentar uma das primeiras

    Full Text Available A new Hemigrammusis described from the rio Paraguai and rio Madeira basins, Mato Grosso and Rondônia States, Brazil. The new species is characterized by possessing a wide dark horizontal stripe across the eye, a vertically elongated humeral blotch, and 4-5 gill-rakers on upper branch and 9-10 on lower. The new species can be easily diagnosed from H. lunatus, the sympatric and morphologically most similar congener, by the shape of humeral blotch and the number of gill rakers. Data of the type material of both Hemigrammus lunatus and H. maxillaris, as well as extensive examination of specimens, allowed us to conclude that H. maxillarisis a junior subjective synonym of H. lunatus. A redescription of H. lunatus, as well as a formal restriction of its type locality, is provided. A putative monophyletic group within Hemigrammus, composed by H. barrigonae, Hemigrammus lunatus, H. machadoi new species, and H. ulreyi, named Hemigrammus lunatus group, is proposed based on overall body morphology and color pattern. Additionally, a discussion on the biogeographical relationships between the rio Paraguai and rio Guaporé basins is provided.

It endevors to delineate a picture of Brazil in relation to the three central themes of the event, namely the relief and reduction of poverty, the expansion of productive employment, and social integration. The first part, aiming to identify the peculiarities of the social chalenges Brazil is faced with, consists of as comprehensive survey of the more relevant general data. The second part, of a conceptual character, inquires into the relationship between social development and justice for all, particularly in the area where economic/social development and economic/social policy diverge. The Report then goes on to the part more directly linked to the central theme of othe Summit. The chapter on poverty endevors to describe some of the main characteristics of this phenomenon in Brazil. Under "Employment and Labor Market", topics such as the low rate of usable unemployment in the Brazilian market place and its relation to the poor quality of available jobs are examined. Finally "Social Integration and social Policy" stressesd the necessity for new structures for social solidarity, which would imply the reorganization of the logistics of financing and its integration in a cohesive plan, together with new partnerships of the State with Society, and of the public with the private sector. By way of conclusion, the main directives of the Federal Government for 1995-1999 are drawn. It emphasizes the need to reach four fundamental conditions, namely the strengthning of democracy, the maintaining of economic stability, the recuperation of sustained growth, and the remodeling of the State.To achieve this, five priority targets in the social area

    Verena Soares Fernandes

    Full Text Available Resumo A preocupação com a qualidade de operação dos sistemas prediais de esgoto sanitário tem motivado empresas especializadas em biotecnologia a investir em produtos compostos por misturas de microrganismos vivos que atuam no pré-tratamento de efluentes de sistemas prediais para combater odores desagradáveis em ambientes sanitários. O objetivo deste artigo é avaliar o uso de misturas concentradas de microrganismos em caixas sifonadas para eliminar o mau cheiro em ambientes sanitários e o impacto em estações de tratamento de esgotos sanitários. O método consiste em diagnosticar o mau cheiro de um dos sanitários de um edifício escolar de nível superior, que é alvo de constantes reclamações por parte dos usuários. Em seguida, introduzir tabletes de microrganismos nas caixas sifonadas e, por fim, avaliar o impacto do uso desse produto em dois sanitários e em estações de tratamento de esgoto por meio de análises de demanda bioquímica de oxigênio e de testes de respirometria. Os resultados indicam que nestes ambientes sanitários o mau cheiro não foi reduzido com o emprego de tabletes de microrganismos e em Estações de Tratamento de Esgoto, na concentração indicada pelo fabricante, o produto não produziu alterações significativas nas características analisadas do esgoto.

Five countries, Botswana, Russia, Canada, South Africa and Angola account for 83% by value and 65% by weight of annual diamond production, which is mainly produced by four major companies, De Beers, Alrosa, Rio Tinto and BHP Billiton (BHPB), which together account for 78% by value and 72% by weight of annual diamond production for 2007. During the last twelve years 16 new diamond mines commenced production and 4 re-opened. In addition, 11 projects are in advanced evaluation and may begin operations within the next five years. Exploration for diamondiferous kimberlites was still energetic up to the last quarter of 2008 with most work carried out in Canada, Angola, Democratic Republic of the Congo (DRC) and Botswana. Many kimberlites were discovered but no new economic deposits were outlined as a result of this work, except for the discovery and possible development of the Bunder project by Rio Tinto in India. Exploration methods have benefitted greatly from improved techniques of high resolution geophysical aerial surveying, new research into the geochemistry of indicator minerals and further insights into the formation of diamonds and the relation to tectonic/structural events in the crust and mantle. Recent trends in diamond marketing indicate that prices for rough diamonds and polished goods were still rising up to the last quarter of 2008 and subsequently abruptly sank in line with the worldwide financial crisis. Most analysts predict that prices will rise again in the long term as the gap between supply and demand will widen because no new economic diamond discoveries have been made recently. The disparity between high rough and polished prices and low share prices of publicly

    This report contains a summary of data compiled from sources throughout the Rio Grande Valley study unit of the National Water-Quality Assessment program. Information presented includes the sources and types of water-quality data available, the utility of water-quality data for statistical analysis, and a description of recent water-quality conditions and trends and their relation to natural and human factors. Water-quality data are limited to concentrations of selected nutrient species in surface water and ground water, concentrations of suspended sediment and suspended solids in surface water, and pesticides in surface water, ground water, and biota.The Rio Grande Valley study unit includes about 45,900 square miles in Colorado, New Mexico, and Texas upstream from the streamflow-monitoring station Rio Grande at El Paso, Texas. The area also includes the San Luis Closed Basin and the surface-water closed basins east of the Continental Divide and north of the United States-Mexico international border. The Rio Grande drains about 29,300 square miles in these States; the remainder of the study unit area is in closed basins. Concentrations of all nutrients found in surface-water samples collected from the Rio Grande, with the exception of phosphorus, generally remained nearly constant from the northernmost station in the study unit to Rio Grande near Isleta, where concentrations were larger by an order of magnitude. Total nitrogen and total phosphorus loads increased downstream between Lobatos, Colorado, and Albuquerque, New Mexico. Nutrient concentrations remained elevated with slight variations until downstream from Elephant Butte Reservoir, where nutrient concentrations were lower. Nutrient concentrations then increased downstream from the reservoir, as evidenced by elevated concentrations at Rio Grande at El Paso, Texas.Suspended-sediment concentrations were similar at stations upstream from Otowi Bridge near San Ildefonso, New Mexico. The concentration and

    mortalidade infantil.The infant mortality rate has been considered a summary of the quality of life and level of development of a given population. However, this indicator is very sensitive to such simple measures as oral rehydration therapy, vaccination, and continuation of breast-feeding. Given that such health activities have become more widespread, an infant mortality rate may no longer reflect a particular development model. With the aim of broadening the discussion regarding infant mortality, this study analyzed the 153 neighborhoods of the city of Rio de Janeiro, Brazil. Our objective was to identify areas with more risk, and the priority groups for interventions to decrease infant mortality. We analyzed neonatal and postneonatal mortality in each neighborhood. We also identified the children's home neighborhood and the location of their deaths and related these results to the socioeconomic classification of the corresponding neighborhoods. In relation to the average infant mortality rate for the city, we could not make statistically significant comparisons for some neighborhoods due to their small number of births. One-third of the infant deaths could have been prevented with early diagnosis and treatment. Only 15% of the deaths were considered unavoidable. Both neonatal mortality and postneonatal mortality were geographically dispersed, with no direct association with the socioeconomic profile of the neighborhoods. An analysis of the children's place of residence and the location of their deaths showed flows of patients from poor areas to more affluent city areas with better health services. This pattern highlights the effect of access to quality medical care on infant mortality.

    The mineralogy of atmospheric particles at the confluence of the Tinto and Odiel rivers, south of Huelva (a highly industrialized city in the SW Spain), was characterized in view to identify source origins. In spite of the small amount of sample collected, mineralogical characterization was performed by X-ray diffraction, polarized light microscopy and scanning electron microscopy with EDS analysis system, using an adequate sample preparation methodology. Sedimentable (SP) and aerosols particles were sampled an one-week basis every two months for one year. Quartz, calcite and feldspars were found to be the major minerals in both fractions, and phyllosilicates, dolomite and gypsum were also identified in lower content. Minor mineral particles included barite, apatite, sphalerite and pyrite. SEM studies revealed the additional presence of chalcopyrite in both SP and aerosols, and of chalcocite-covellite, halite and sylvite in the latter. Siderite, hematite and ankerite were only detected in the SP fraction. The concentrations of the previous minerals increased in summer by effect of the limited rain and the resulting scarcity of atmosphere washing. Non-mineral particles detected by SEM in SP and aerosol fractions included spherical, biological and compositionally complex particles. The main source of mineral particles was found to be the soil suspension in addition to the metallurgical and fertilizer production industries in the area.

Visto como uma etapa importante na reconstitucionalização do país, na medida em que prevê a submissão dos comandantes das Forças Armadas a um ministro civil, e embora alguns analistas considerem que essa submissão de fato ocorre, procuramos indicar as resistências e as insubordinações militares ao poder civil, provenientes de um legado autoritário. Na medida em que o Ministério da Defesa não consegue implementar uma política própria, em que os militares seguiriam as orientações dos civis, o artigo conclui considerando a fragilidade política e institucional do Ministro da Defesa, civil, ante o os comandos militares, que conservam alto grau de autonomia decisória em relação à estrutura do Ministério.

    The Rio Dulce National Park is one of Guatemala's major environmental assets. The park contains the remaining remnants of an eastern Guatemalan tropical rainforest which has good but fast deteriorating value for the development of the ecotourism industry. The governmenial objective for the region as stated in the Master Plan for the park is ecotourism development and protection of biodiversity. The decisions to be made concerning the long-term, sustainable use of the natural resources of the Rio Dulce region appear to be directed by existing environmental laws and the Rio Dulce Master Plan. However, the wording of these instruments is ambiguous and lacks specific definitions and criteria for making necessary determinations. This, in combination with lack of enforcement in the region, has led to extensive disparity in interpretation of the laws and uncontrolled, conflicting actions by individuals and organizations.

O processo de urbanização freqüentemente produz alterações na drenagem da água pluvial. Um SIG com dados cadastrais planaltimétricos e fotografias aéreas permitiram estudar a ocupação em 3 diferentes períodos (1999, 1986 e 1971 na sub-bacia do Centenário, na cidade de Lavras, MG. Objetivou-se com este estudo realizar a análise temporal da permeabilidade da superfície na sub-bacia do Centenário comparando os 3 períodos. A permeabilidade da superfície urbana foi obtida pela análise da ocupação dos quarteirões por área construída ou pavimentada. Os resultados permitiram verificar que a permeabilidade da superfície decaiu de 1971 para 1999. Nestes anos a área urbana cresceu reduzindo a permeabilidade do solo da sub-bacia. Conclui-se que, sendo óbvio que a urbanização causou impactos na sub-bacia, as metodologias utilizadas para essas análises foram muito eficientes para determinar os impactos de superfícies impermeáveis.Over the past years, a series of studies have been undertaken by scientists of different areas, to assess the effects of urbanization on the hidrology of subbasins.

    Full Text Available This article presents the application of a methodology with geoprocessing tools to verify the existence (or not of spatial conflicts between land use organizing instruments in the Casino Beach region and surrounding areas in the municipality of Rio Grande-RS. Therefore, the following legal instruments were analyzed: Planning Units, the Master Plan component, Ecological Economic Zoning Municipal- ZEEM, the Municipal Environmental Plan component and Map of Environmental Legal Basis generated by the authors based on Permanent-APPs Preservation Areas, Units Conservation and other areas with legally defined usage restrictions. We used the software Geographic Information Systems QGIS; one satellite image RapidEye® and vector data for processing. They resulting products were: land cover map, the environmental legal basis map and maps of conflicts based on crossing data. It was found that the class with largest soil coverage areas are fields (50.5%, followed by swamps and marshland (25.2%. And that 34.55% of the mapped area correspond to legally protected areas. As for the data conflicts, we found scale problems especially at the edges because the Planning Units are in scale of 1: 10,000; while ZEEM is 1: 100,000 and the Environmental Legal Basis is in scale 1: 25.000. Another problem encountered was the failure of the Planning Units for most of the study area. It was also found the importance of delimiting the PPAs and that the overlap of these environments with the other two policies would solve much of the spatial conflicts found. The fact is that there are two instruments of public policy for the same territory that are in conflict, which highlights the importance of integrating public institutions and geospatial data in the regulation and management of the territory.

In Brazil, the National Nuclear Energy Commission (CNEN) is responsible for Intermediate Radioactive Waste deposits, located in Fundao Island, Rio de Janeiro (RJ). According to CNEN 8.01 norm, it is necessary to characterize and to study the location area around the deposit. Within this context, the objective of this study was to characterize the Canal Cunha Basin, the western of Guanabara Bay and study the Environmental Impact, with determination of heavy metals (Pb, Cu, Cd, Zn and Ni) in said river basin and bay. The work involves collecting water and sediment samples in five georeferenced points. The sediment samples was collected using the EPA Method 3051 and the reading of the concentrations of heavy metals in water and sediment was performed by ICP-OES.

The results show that in periods of high river discharge, there is a drift of large amounts of Pb, Cu and Cd to the waters of the Canal Cunha and Guanabara Bay. Zn and Ni presented higher concentrations in the dry season. The Pb, Cu, Cd, Zn and Ni concentrations are smaller than the concentrations found in the sediment. This probably happens because Cunha Canal Basin and western of Guanabara Bay receive high organic load, and also because of the high percentage of fine sediment in this, thus promoting the adsorption of metals, not contaminating the water and thus not reaching the food chain.

However, there is a lack of knowledge on their fish fauna in many areas, including headwaters. The present study aimed to describe the fish community structure from Juramento reservoir, located on Juramento River, a branch of SFR basin. Six bimonthly samplings were made in four different sites. Gill and cast nets, beach seines and sieves were used to collect fish. Ecological indexes as well as the relationship between fish abundance and some limnological variables were determined. 3288 fish belonging to 33 species (16.5% of the total described for SFR basin were captured, being 75.7% Characiformes, 18.1% Siluriformes, 3% Cyprinodontiformes and 3% Gymnotiformes. Only two non-native species, 'tamboatá' - Hoplosternum littorale (Hancock, 1828 and 'trairão' - Hoplias lacerdae Ribeiro, 1908 were found. The highest catches in number occurred in the dry period (March-October and the lowest one in the wet season (November-February. Diversity was higher at Barragem station and richness did not vary between reservoir zones. Five migratory species were found downstream of the dam (four exclusively there, whereas only the 'curimbatá-pioa' - Prochilodus costatus Valenciennes, 1850 occurred in the reservoir. The low observed correlations between fish abundance and the limnological variables utilized suggest that the local fish fauna is not strongly affected by their variation.No Brasil, vários rios, como os da bacia do São Francisco (RSF, são barrados para a formação de reservatórios.

    Granitoids and gneisses occurring at Rio Maria, Mata Geral farm and Itacaiunas river regions, southern Para, underwent radiometric age determinations by Rb/Sr method using conventional isochrons. Results obtained from the Rio Maria and Mata Geral farm regions allowed te establishment of a reference 2,600 my Rb/Sr isochron with an initial Sr 87 /Sr 86 ratio of 0.7009. This result resembles the one obtained for granitoids and gneisses hosting rocks of the Serra do Inaja greenstone belt, located some what south of this area, which yielded, in Rb/Sr isochron, a radiometric age of 2,696 + - 79 my with an initial Sr 87 /Sr 86 ratio of 0.701. Results obtained from the Itacaiunas river region allowed for the establishment of a Rb/Sr referential isochron of 2,480 + - 40 my wth an initial Sr 87 /.Sr 86 ratio of 0.7072. Due to low initial ratios, it is suggested that the rocks from the Rio Maria, Mata Geral farm and Serra do Inaja regions formed from Mafic crust or superior mantle reworking, while those from the Itacaiunas river region, due to a high initial ratio, result from reworking at high crustal levels.

    Samples of ''sandstone'' from near the site of the upper Rio Blanco nuclear explosion were heated in the laboratory at temperatures between 600 and 900 0 C. The composition and amount of noncondensable (dry) gas released were measured and compared to the amount and composition of gas found underground following the explosion. The gas released from the rock heated in the laboratory contained approximately 80 percent CO 2 and 10 percent H 2 ; the balance was CO and CH 4 . With increasing temperature, the amounts of CO 2 , CO, and H 2 released increased. The composition of gas released by heating Rio Blanco rock in the laboratory is similar to the composition of gas found after the nuclear explosion except that it contains less natural gas (CH 4 , C 2 H 6 . . .). The amount of noncondensable gas released by heating the rock increases from approximately 0.1 mole/kg of rock at 600 0 C to 0.9 mole/kg at 900 0 C. Over 90 percent of the volatile components of the rock are released in less than 10 h at 900 0 C. A comparison of the amount of gas released by heating rock in the laboratory to the amount of gas released by the heat of the Rio Blanco nuclear explosion suggests that the explosion released the volatile material from about 0.42 mg of rock per joule of explosive energy (1700 to 1800 tonnes per kt).

    We use stratigraphic relations, paleoflow data, and 40Ar/39Ar dating to interpret net aggradation, punctuated by at least two minor incisional events, along part of the upper ancestral Rio Grande fluvial system between 5.5 and 4.5 Ma (in northern New Mexico). The studied fluvial deposits, which we informally call the Sandlin unit of the Santa Fe Group, overlie a structural high between the San Luis and Española Basins. The Sandlin unit was deposited by two merging, west- to southwest-flowing, ancestral Rio Grande tributaries respectively sourced in the central Taos Mountains and southern Taos Mountains-northeastern Picuris Mountains. The river confluence progressively shifted southwestward (downstream) with time, and the integrated river (ancestral Rio Grande) flowed southwards into the Española Basin to merge with the ancestral Rio Chama. Just prior to the end of the Miocene, this fluvial system was incised in the southern part of the study area (resulting in an approximately 4–7 km wide paleovalley), and had sufficient competency to transport cobbles and boulders. Sometime between emplacement of two basalt flows dated at 5.54± 0.38 Ma and 4.82±0.20 Ma (groundmass 40Ar/39Ar ages), this fluvial system deposited 10–12 m of sandier sediment (lower Sandlin subunit) preserved in the northern part of this paleovalley. The fluvial system widened between 4.82±0.20 and 4.50±0.07 Ma, depositing coarse sand and fine gravel up to 14 km north of the present-day Rio Grande. This 10–25 m-thick sediment package (upper Sandlin unit) buried earlier south- to southeast-trending paleovalleys (500–800 m wide) inferred from aeromagnetic data. Two brief incisional events are recognized. The first was caused by the 4.82±0.20 Ma basalt flow impounding south-flowing paleodrainages, and the second occurred shortly after emplacement of a 4.69±0.09 Ma basalt flow in the northern study area. Drivers responsible for Sandlin unit aggradation may include climate

    Full Text Available The aim of this research was to report the occurrence of two species of thrips in watermelon crops in the semiarid region of Rio Grande do Norte, Brazil. From August to September 2011, we performed weekly sampling of thrips in a commercial watermelon production area with 10,000m2, using 20 Moericke traps. We captured a total of 431 thrips, belonging to Frankliniella schultzei (Trybom (Thripidae and Haplothrips gowdeyi (Franklin (Phlaeothripidae. This is the first report of H. gowdeyi in watermelon crops in Brazil

    Full Text Available A new species of Hisonotus is described from the rio São Francisco basin. The new species can be distinguished from congeners by having (1 a unique coloration pattern of caudal fin with one black spot extending from its origin to the ventral lobe and two dark spots at the end of the lobe’s rays; (2 odontodes forming longitudinally aligned rows on head and trunk; (3 a functional V-shaped spinelet; (4 a single rostral plate at the tip of the snout; (5 by lacking contrasting dark geometric spots on the anterodorsal region of the body; (6 a lower caudal-peduncle depth; and (7 lower counts of the lateral median plates and (8 higher premaxillary and dentary teeth. The new species is the second described species of the genus Hisonotus in the rio São Francisco basin. It was found inhabiting the marginal vegetation of the rio São Francisco and three of its tributary, rio das Velhas, rio Paraopeba and rio Formoso.

    Full Text Available The rio das Velhas, located in central Minas Gerais State (Brazil, is a major tributary of the rio São Francisco. Despite several anthropogenic pressures, this basin supports more than 115 fish species. The aim of this study was to compare the morphological space occupied by fish assemblages in four regions (headwaters, upper, middle, and lower course along the channel of the rio das Velhas. We try to answer the following question: Is there a change in the morphological organization of the fish along the longitudinal gradient of the river? Individuals from 67 species, collected at several sites in the basin from 1999 to 2008, were measured for 11 morphological attributes related to swimming behavior and habitat use. Through the graphs, the first two dimensions of the PCA suggest that the morphological volume occupied by the headwaters region is smaller than the other sections, because of the low richness of the site. However, morphological hypervolumes of the four reaches analyzed by Euclidean distances were not statistically different. The results indicated that only the density of morphological types increases along the rio das Velhas, and there is no difference between the headwaters and upper courses. Therefore, in order to use functional groups related to the morphology of the species as tools to take measures for the conservation and revitalization of the rio das Velhas, it is necessary analyze the density of species within these groups, as well as their composition.O rio das Velhas, localizado na região central do estado de Minas Gerais (Brasil, é o mais extenso tributário do rio São Francisco. Apesar dos inúmeros impactos antrópicos que sofre, sua bacia abriga uma rica ictiofauna, com mais de 115 espécies conhecidas. O objetivo deste estudo foi comparar o espaço morfológico ocupado pelas assembleias de peixes em quatro regiões (cabeceira, alto curso, médio curso e baixo curso ao longo da calha do rio das Velhas.

    Full Text Available The Rio Grande do Sul is the largest producer of rice. In the state, rice is conventionally produced in large areas with intensive use of machinery and inputs, which has been associated with environmental impacts. Innovation can help to change this reality. Some initiatives are being developed in recent years trying to adapt the conventional system the global trend of consumption concerned about the environment. An example is the production of organic rice. In this sense, has established itself as objective to identify the groups of organic production in the state of Rio Grande do Sul and the innovations associated with these groups. The research was characterized as qualitative. The current stage of research enabled us to identify the group of producers associated with the Center for Environmental Education and Rice Agroecological Management Group, coordinated the Cooperative Central Settlements of Rio Grande do Sul. Have been identified other producers or groups. As for innovations, the results of the group of producers associated with the Center for Environmental Education and Monitoring are under review. Still it was found that new more sustainable alternatives are being adopted by producers and that this type of cultivation has increased in recent seasons.DOI: 10.5902/198346597782O Rio Grande do Sul é o maior produtor brasileiro de arroz.
