  1. Hyacinths Choke the Rio Grande

    These images acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), flying aboard NASA's Terra satellite, demonstrate the potential of satellite-based remote sensors to monitor infestations of non-native plant species. These images show the vigorous growth of water hyacinths along a stretch of the Rio Grande River in Texas. The infestation had grown so dense in some places it was impeding the flow of water and rendered the river impassible for boats. The hyacinth is an aquatic weed native to South America. The plant is exotic looking and, when it blooms, the hyacinth produces a pretty purple flower, which is why it was introduced into North America. However, it has the capacity to grow and spread at astonishing rates so that in the wild it can completely clog the flow of rivers and waterways in a matter of days or weeks. The top image was acquired on March 30, 2002, and the bottom image on May 9, 2002. In the near-infrared region of the spectrum, photosynthetically-active vegetation is highly reflective. Consequently, vegetation appears bright to the near-infrared sensors aboard ASTER; and water, which absorbs near-infrared radiation, appears dark. In these false-color images produced from the sensor data, healthy vegetation is shown as bright red while water is blue or black. Notice a water hyacinth infestation is already apparent on March 30 near the center of the image. By May 9, the hyacinth population has exploded to cover more than half the river in the scene. Satellite-based remote sensors can enable scientists to monitor large areas of infestation like this one rather quickly and efficiently, which is particularly useful for regions that are difficult to reach from on the ground.

  3. Optics along the Rio Grande Research Corridor

    International Nuclear Information System (INIS)

    New Mexico's scientific, technological, and educational resources are concentrated along a 300-mile stretch of the Rio Grande, from Los Alamos in the north to the Las Cruces in the south. This area contains two major multidisciplinary national laboratories (Los Alamos and Sandia), three military R and D centers, three state universities, and numerous other technology-based organizations, including a growing number of ''high-tech'' businesses and industries. The state of New Mexico has initiated a program to develop these resources for economic growth through the establishment of the Rio Grande Research Corridor. Much of the future development along the Corridor will involve optics and optical technologies. This session of the Southwest Conference on Optics reviewed the various projects in the Rio Grande Research Corridor, focusing on applications of optics

    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.

    The Rio Grande River stretches over 2000 miles from the southern Rocky Mountains in Colorado to the tip of Texas where the Rio Grande meets the Gulf of Mexico. It is the natural boundary between U.S. and Mexico from El Paso, TX, to Brownsville, TX. The communities along the border heavily rely upon the Rio Grande as a primary source of water for consumption, agricultural uses, supporting wildlife and recreation. For many years the Rio Grande has been polluted with municipal, industrial, agricultural and farming contaminants from both sides of the border. This pollution has led to the extinction or reduction of certain wildlife species as well as affecting the health of the residences along the border. Even though great strides have been made in monitoring the Rio Grande, there has been a lack of intense monitoring data collection for pollutants such as pesticides. Three sampling sites including Manadas Creek, the Rio Grande River at International Bridge I, and USGS monitoring site 08459200 off of Highway 83 were chosen. The water quality parameters focused include temperature, pH, conductivity, dissolve oxygen (DO), salinity, total dissolved solids, nutrients, metals and pesticides. Preliminary results have shown elevated concentration of total phosphorus and ortho-phosphorus in the Manadas Creek site. Organochlorinated pesticides such as heptachlor and 4, 4 DDE were detected at various concentrations at all sites and endrin aldehyde was found at Manadas Creek site. This research has provided more information on the current chemical contamination level of the Rio Grande in the Laredo area.

Foram escolhidos três locais, com 50 m de distância um do outro, sendo que em cada local foram fundeadas três transversais 2 m equidistantes. Cada transversal estendeu-se da base das dunas primárias até aproximadamente 1 m de profundidade no infralitoral. A distância dos níveis de coleta em cada transversal foi de 20 m até o limite superior da zona de varrido, a partir do qual a distância foi de 10 m. Em algumas ocasiões foi evidenciada variação espacial horizontal de alguns dos principais táxons, bem como da comunidade bentônica dentro de uma escala de 50 m e 100 m. Esta variação foi provavelmente reflexo da ação das marés meteorológicas que causam abrupta elevação do nível do mar.

  16. Late archaic settlement systems in the northern Rio Grande

    2003-01-01

    Last year at these meetings I proposed a possible seasonal transhumance pattern for the Late Archaic in the northern Rio Grande region. This pattern involved the movement of groups from the lowland juniper-savanna grasslands in the early summer, to the upland ponderosa pindmixed conifer forests in the mid to late summer, and then back down to the piiion-juniper woodlands during the fall. The Rio Grande Valley was also used for winter habitation sites. Following on this research, I take the next step by studying the inter-assemblage variability represented in a sample of open-air sites located within each of these vegetation communities. The results indicate that there are significant differences in reduction tactics represented between valley habitation vs., upland campsites, and that these site sites are linked together by obsidian procurement patterns.

    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 significant correlation was

  3. Geomorphology of plutonium in the Northern Rio Grande

    International Nuclear Information System (INIS)

    Nearly all of the plutonium in the natural environment of the Northern Rio Grande is associated with soils and sediment, and river processes account for most of the mobility of these materials. A composite regional budget for plutonium based on multi-decadal averages for sediment and plutonium movement shows that 90 percent of the plutonium moving into the system is from atmospheric fallout. The remaining 10 percent is from releases at Los Alamos. Annual variation in plutonium flux and storage exceeds 100 percent. The contribution to the plutonium budget from Los Alamos is associated with relatively coarse sediment which often behaves as bedload in the Rio Grande. Infusion of these materials into the main stream were largest in 1951, 1952, 1957, and 1968. Because of the schedule of delivery of plutonium to Los Alamos for experimentation and weapons manufacturing, the latter two years are probably the most important. Although the Los Alamos contribution to the entire plutonium budget was relatively small, in these four critical years it constituted 71--86 percent of the plutonium in bedload immediately downstream from Otowi

    The Rio Grande Oil Company Refinery (Rio Grande I) site is a proposed National Priorities List site located adjacent to the City of Sour Lake in Hardin County, Texas. Rio Grande I was the site of an oil refinery in the 1920s and 1930s. Refinery wastes were disposed of on site in open, unlined pits. A privately-funded remediation effort removed 3,410 cubic yards of waste material from the site in November 1987. Elevated levels of mercury, zinc, and bis(2-ethylhexyl)phthalate were detected in soil on site after remediation. No groundwater contamination was detected. Based on the available environmental sampling information, the Rio Grande I site is not of public health concern under current conditions.

The Texas curriculum was also changed to include Astronomy and Space Science requirement in the tests students need to take to prove their academic preparedness. The teachers worked through a variety of inquiry-based, hands-on activities after a short presentation on the background science. In order to evaluate our effectiveness, we have asked the teachers to take pre- and post-workshop tests, and we asked them to fill out a self-reflective survey. We will report on our experiences, what works best with the teachers, and in what areas we still have a long way to go.This work was supported by various NASA education grants and Cooperative agreements, as well as grants provided by the Texas Space Grant Consortium.

    Full Text Available We conducted a molecular epidemiological study to investigate HIV-1 strains in Rio Grande, southern Brazil, searching for an association with transmission mode and risk behavior. Patients (185 identified at an AIDS treatment reference Hospital, from 1994 to 1997, were included; from which 107 blood samples were obtained. Nested PCR was realized once for each sample; for amplified samples (69 HIV subtypes were classified using the heteroduplex mobility assay. Subtypes identified were B (75%, C (22% and F (3%. All infections with C were diagnosed after 1994. Comparing patients with B and C, no differences were detected regarding demographic, clinical and laboratory characteristics; survival analysis did not reveal differences in HIV to AIDS evolution. A higher proportion of injecting drug users, IDU (not significant, p<.07 was found among those with C. This suggests that C may have been introduced in this area through IDU, and is being spread, probably by their sexual partners, to persons with other risk practices.

  12. Magnetotelluric pilot study in the Rio Grande Rift, southwest USA

    2012-12-01

    A magnetotelluric (MT) pilot study consisting of approximately 25 stations distributed in and around the Rio Grande Rift of the southwest United States was carried out in the summer of 2012. Both broadband (100 Hz to 1000 s) and long-period (up to 10 000 s) MT data were collected across two profiles that run perpendicular to the rift axis near Denver, Colorado and Taos, New Mexico, respectively. Time-domain EM data was also collected at each site to account for galvanic distortion in the near-surface. The tectonic forces and rheologic properties behind the initiation and propagation of the rift are poorly understood. Surface mapping of volcanism, normal faulting and sedimentary basins reveals a narrow band of crustal deformation confined to a region in close proximity to the rift axis while geophysical results suggest that deformation is distributed across a much broader and deeper region of the lithosphere. In particular, seismic tomography shows low seismic wave speeds into the lower crust and upper mantle. The magnetotelluric technique is a well-proven passive electromagnetic method that allows for the detection of apparent resistivity at a wide range of depth scales. Complimenting the seismic results with MT data will provide important new information on the geologic and geophysical properties that control the rifting process in this low-strain rate environment. Properties to which the MT method is particular sensitive include temperature, fluid content, and mineral alteration. Preliminary results from this most recent survey are encouraging, showing good data quality up to 10 000 s. In an important precursor to full 2D modeling, the magnetotelluric phase tensor has been used to assess the dimensionality of the electrical resistivity structure at depth. This pilot study provides proof of concept for a much larger magnetotelluric experiment planned to take place in the Rio Grande Rift in 2013.

  14. Upwarp of anomalous asthenosphere beneath the Rio Grande rift

    Continental rifts are possible analogues of mid-ocean ridges, although major plate tectonic features are less clearly observed1. Current thermal models of mid-ocean ridges2-4 consist of solid lithospheric plates overlying the hotter, less viscous asthenosphere, with plate thickness increasing away from the ridge axis. The lithospheric lower boundary lies at or near the melting point isotherm, so that at greater depths higher temperatures account for lower viscosity, lower seismic velocities and possibly partial melting. Upwarp of this boundary at the ridge axis concentrates heat there, thus lowering densities by expansion and raising the sea floor to the level of thermal isostatic equilibrium. At slow spreading ridges, a major central graben forms owing to the mechanics of magma injection into the crust5. Topography, heat flow, gravity and seismic studies support these models. On the continents, a low-velocity channel has been observed, although it is poorly developed beneath ancient cratons6-9. Plate tectonic models have been applied to continental basins and margins10-12, but further similarities to the oceanic models remain elusive. Topographic uplift is often ascribed to Airy type isostatic compensation caused by crustal thickening, rather than thermal compensation in the asthenosphere. Here we discuss the Rio Grande rift, in southwestern United States. Teleseismic P-wave residuals show that regional uplift is explained by asthenosphere uplift rather than crustal thickening. ?? 1984 Nature Publishing Group.

    Full Text Available Salmonella spp. was the major cause of reported foodborne diseases in the last years in the State of Rio Grande do Sul, South of Brazil. Epidemiological data on salmonellosis, occurred in the period of 1997 to 1999 and supplied by the Division of Sanitary Surveillance (DVS/RS, were analysed according to the following factors: total number of confirmed outbreaks, number of people involved, outbreaks incidence according to the period of the year, age and sex of involved people, food vehicle, food storage conditions, local where the disease occurred, and possible causes of the outbreaks. The results indicated that 8217 people were involved, and 1557 had to be hospitalized. The highest number of outbreaks occurred during springtime and the principal age group affected was between 16 and 50 years. The most common food vehicle was salad prepared with homemade mayonnaise (42.45%. The principal causes of salmonellosis were raw-materials not submitted to regulatory inspection (22.92%, mainly eggs, and foods maintained at room temperature for more than 2 hours (20.55%. The majority of the outbreaks occurred in private homes (43.70% and commercial food establishments (25.21%.

    Full Text Available Resumo ----- O turismo tem sido entendido por organismos internacionais como atividade com grande potencial para promover o desenvolvimento econômico e, ao mesmo tempo, que valoriza a cultura e promove a preservação das paisagens naturais. Seguindo as diretrizes internacionais, no Brasil, o turismo passou a ser entendido como uma indústria com grande potencial para gerar empregos e divisas, e se fortalece por meio da promoção da diversidade cultural, que pode estar associada às diversas culturas materiais e religiosas. Para compreender a gestão do turismo em contextos que articulam cultura, religião e desenvolvimento territorial, este ensaio teórico aponta limitações nos dois conceitos disponíveis na literatura, quais sejam, o conceito de turismo cultural e o conceito de turismo religioso, ao mesmo tempo que propõe o conceito de ‘turismo em territórios de grande densidade religiosa’, o qual incorpora o reconhecimento das dinâmicas de poder presentes nos territórios como elementos que interferem na forma como se planeja o turismo. Mobilizam-se entendimentos do campo da antropologia e da geografi a para a gestão a fim de sustentar que a discussão teórica conduzida tem um potencial explicativo para o turismo em diversas escalas territoriais, e, também, em contextos nos quais existe o diálogo entre turismo e religião. ----- Tourism in Territories of High Religious Density ----- Abstract ----- Tourism has been understood by international organizations as an activity with great potential to promote economic development, while valuing cultures and promoting the protection of natural landscapes.

    Surveys for amphibians along large rivers pose monitoring and sampling problems. We used canoes at night to spotlight and listen for anurans along four stretches of the Rio Grande in Big Bend National Park, Texas, in 1998 and 1999. We explored temporal and spatial variation in amphibian counts and species richness and assessed relationships between amphibian counts and environmental variables, as well as amphibian-habitat associations along the banks of the Rio Grande. We documented seven anuran species, but Rio Grande leopard frogs (Rana berlandieri) accounted for 96% of the visual counts. Chorus surveys along the river detected similar or fewer numbers of species, but orders of magnitude fewer individuals compared to visual surveys. The number of species varied on average by 37% across monthly and nightly surveys. We found similar average coefficients of variation in counts of Rio Grande leopard frogs on monthly and nightly bases (CVs = 42-44%), suggesting that canoe surveys are a fairly precise technique for counts of this species. Numbers of Rio Grande leopard frogs observed were influenced by river gage levels and air and water temperatures, suggesting that surveys should be conducted under certain environmental conditions to maximize counts and maintain consistency. We found significant differences in species richness and bullfrog (Rana catesbeiana) counts among the four river stretches. Four rare anuran species were found along certain stretches but not others, which could represent either sampling error or unmeasured environmental or habitat differences among the river stretches. We found a greater association of Rio Grande leopard frogs with mud banks compared to rock or cliff (canyon) areas and with seepwillow and open areas compared to giant reed and other vegetation types. Canoe surveys appear to be a useful survey technique for anurans along the Rio Grande and may work for other large river systems as well.

  15. Water Management for Competing Uses: Environmental Flows in the Transboundary Rio Grande/Rio Bravo

    Science.gov (United States)

    Sandoval Solis, S.; McKinney, D. C.

    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

  17. DAM IMPACTS ON AND RESTORATION OF AN ALLUVIAL RIVER - RIO GRANDE, NEW MEXICO

    Institute of Scientific and Technical Information of China (English)

    Gigi RICHARD; Pierre JULIEN

    2003-01-01

    The impact of construction of dams and reservoirs on alluvial rivers extends both upstream and downstream of the dam. Downstream of dams, both the water and sediment supplies can be altered leading to adjustments in the river channel geometry and ensuing changes in riparian and aquatic habitats.The wealth of pre and post-regulation data on the Middle Rio Grande, New Mexico, provides an excellent case study of river regulation, channel adjustments, and restoration efforts. Cochiti Dam was constructed on the main stem of the Rio Grande in 1973 for flood control and sediment retention. Prior to dam construction, the Rio Grande was a wide, sandy braided river. Following dam construction, the downstream channel bed degraded and coarsened to gravel size, and the planform shifted to a more meandering pattern. Ecological implications of the geomorphic changes include detachment of the river from the floodplain, reduced recruitment of riparian cottonwoods, encroachment of non-native saltcedar and Russian olive into the floodplain, and degraded aquatic habitat for the Rio Grande silvery minnow.Recent restoration strategies include removal of non-native riparian vegetation, mechanical lowering of floodplain areas, and channel widening.

    Full Text Available The genus Xylocopa Latreille in Rio Grande do Sul, Brazil (Hymenoptera, Anthophoridae. A survey of the genus Xylocopa Latreille, 1802 is given for Rio Grande do Sul, the southernmost State of Brazil. Data are based on several studies on the bee fauna of southern Brazil and on unpublished observations. A key is provided to the species (males and females and information on distribution, nesting habits and relation to flowers. Rio Grande do Sul is strikingly rich in species of Xylocopa because of the diversity of habitats and its geographic position in the transition of tropical/subtropical to temperate climate.

  5. Social, political, and institutional setting: Water management problems of the Rio Grande

    Douglas, A.J.

    2009-01-01

    This paper discusses various water management issues facing federal, state, and local agencies charged with managing the water resources of the Rio Grande River Basin and its major tributaries. The Rio Grande - 3,058 km (=1,900 mi) long - is the fourth longest river in the United States. The river's basin is 870,236 km2 (=336,000 mi2) and for roughly two-thirds of its length it forms the United States-Mexican border. It is a major recreational resource providing world class trout fishing near its headwaters in Colorado's San Juan Mountains and shoreline, angling, and boating opportunities near the Colorado-New Mexico border. The Rio Grande is the principal tourist attraction of Big Bend National Park and flows through downtown Albuquerque and El Paso. Many reaches are wide and broad, but almost all are relatively shallow and not navigable by commercial ships. Nevertheless, it is one of the most important renewable water resources of the southwestern United States and North America. The issue of the "manageability" of the river in the face of social forces and disparate administrative jurisdictions that adversely impact Rio Grande flows is a thread linking various sections of the paper together. The length of the river; the fact that major reaches lie in Colorado, New Mexico, and Texas; and its unique role as an international boundary pose complex management problems. The allocation status quo formed by the complex nexus of existing river laws make it difficult to reshape Rio Grande management. ?? 2009 ASCE.

    The Yacuiba - Rio Grande Gas Pipeline is remote operated from the Supervision and Control Center (CSC) located in the offices of Transierra S.A. in Santa Cruz de la Sierra, Bolivia. This operation is made by means of a SCADA system based on satellite communication, it starts off at Yacuiba and finishes in Rio Grande, where it deliveries the export gas to Brazil. An Advanced Functions application was developed at the Transierra's CSC, This application runs under Intellution's iFix (HMI of the SCADA) in a Windows platform. It gathers transportation data in real time and by means of a mathematical process and a steady state simulation it makes the following on line calculations: Line Pack, Leak Detection, Transport Efficiency, Pressure Estimate in intermediate points and gas real velocity in the pipeline. The application was developed using Visual BASIC for Applications (VBA) (included in Intellution's iFix) and by means of an interphase to a historical server (iHistorian, Intellution) it is possible to store the obtained results, this integration also allows for the creation of graphs and trends with a great flexibility and to activate alarm points. With a practically null investment, this application replaces high cost specialized packages that are accessories to simulation or SCADA applications. (author)

  14. Economic impact of alternative policy responses to prolonged and severe drought in the Rio Grande Basin

    Science.gov (United States)

    Booker, James F.; Michelsen, Ari M.; Ward, Frank A.

    2005-02-01

    In the Rio Grande Basin, water is overallocated, demands are growing, and river flows and uses are vulnerable to drought and climate change. Currently, the basin is in the third year of severe drought; irrigation and municipal water diversions have been severely curtailed; extensive diversions threaten endangered species, and reservoir volumes are nearly depleted. A central challenge is development of policies that efficiently and equitably allocate the basin's water resources among competing uses across political and institutional jurisdictions. A basin-wide, nonlinear programming model optimizes resource allocations and water use levels for the upper part of the Rio Grande Basin to test whether institutional adjustments can reduce damages caused by drought. Compared to existing institutions, we find that future drought damages could be reduced by 20 and 33% per year through intracompact and interstate water markets, respectively, that would allow water transfers across water management jurisdictions. Results reveal economic tradeoffs among water uses, regions, and drought control strategies.

    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.

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    The Domingos Petrolini Swamp, located on the Southern Coastal Plain of Rio Grande do Sul, near the town of Rio Grande, constitutes an ample holocene lagoonal deposit. Events related to the holocene transgression and their diverse phases of glacial-eustatic ocillations were found through palynological analysis. Bases on these palynological data, four distinct phases to the paleoenvironmental evolution of the ecosystem were identified. It has also shown a transgressive restricted marine sequence on the base, which suggests the existence of a coastal brackish lagoon or a marisme type of environment. Later, there was a gradation for continentality conditions along with a scarce pollinical record. The third phase is characterized by the presence of marine components and halophyte vegetation, showing another transgressive event in that place. Lastly, the end of direct marine influence over the swamp was recorded and also the vegetation development as it appears these days.

  18. Geohydrology of White Rock Canyon of the Rio Grande from Otowi to Frijoles Canyon

    International Nuclear Information System (INIS)

    Twenty-seven springs discharge from the Totavi Lentil and Tesuque Formation in White Rock Canyon. Water generally acquires its chemical characteristics from rock units that comprise the spring aquifer. Twenty-two of the springs are separated into three groups of similar aquifer-related chemical quality. The five remaining springs make up a fourth group with a chemical quality that differs due to localized conditions in the aquifer. Localized conditions may be related to recharge or discharge in or near basalt intrusion or through faults. Streams from Pajarito, Ancho, and Frijoles Canyons discharge into the Rio Grande in White Rock Canyon. The base flow in the streams is from springs. Sanitary effluent in Mortandad Canyon from the treatment plant at White Rock also reaches the Rio Grande

    In the 1960s and 1970s numerous bridges were built in the US with a design similar to those on Interstate 40 (I-40) over the Rio Grande in Albuquerque, New Mexico. The Federal Highway Administration (FHWA) and the National Science Foundation (NSF) have provided funds to New Mexico State University (NMSU) through the New Mexico State Highway and Transportation Department (NMSH and TD) and The Alliance For Transportation Research (ATR) for evaluation and testing of the existing fracture-critical bridges over the Rio Grande. Because the I-40 Bridges over the Rio Grande were to be razed during the summer of 1993, the investigators were able to introduce damage into the structure in order to test various damage identification methods and to observe the changes in load paths through the structure caused by the cracking. To support this research effort, NMSU contracted Los Alamos National Laboratory (LANL) to perform experimental modal analyses, and to develop experimentally verified numerical models of the bridge.

    Full Text Available As leguminosas forrageiras, além de contribuírem para o aumento da oferta de forragem com alto teor de proteína, também são importantes como cobertura vegetal de solos. Entre as leguminosas com grande potencial forrageiro, espécies do gênero Lotus têm se destacado. Este trabalho visou à seleção de rizóbios nativos eficientes em Lotus glaber a partir de amostras de solo de cinco localidades do Rio Grande do Sul. Obtiveram-se 259 isolados de rizóbios, que foram avaliados quanto à morfologia colonial e produção de melanina. Destes, 15 isolados foram selecionados para avaliação da eficiência na fixação simbiótica de nitrogênio em experimento em casa de vegetação e caracterizados geneticamente por comparação do perfil eletroforético dos produtos de amplificação do DNA genômico, por PCR com os oligonucleotídeos iniciadores BOX e ERIC. Apenas cinco isolados produziram melanina. Nove isolados foram mais eficientes do que a estirpe SEMIA 830, que é autorizada para a produção de inoculante para L. glaber no país. Na caracterização genética, observou-se que nenhum isolado apresentou identidade com as estirpes recomendadas, o que demonstra que, nos solos do Rio Grande do Sul, existem rizóbios autóctones eficientes na fixação simbiótica de nitrogênio com L. glaber, podendo ser recomendados para estudos a campo, visando a uma futura produção de inoculantes para estas leguminosas no Brasil.Forage legumes besides contributing to increase the supply of high protein content forage are also good cover for the soil surface. Among the legumes with high potential forage, the genus Lotus has been outstanding. This research aimed to selectnative rhizobia efficient in fixing nitrogen with Lotus glaber, from soil samples of five localities of Rio Grande do Sul. A total of 259 rhizobia isolates were obtained, which were evaluated based on colony morphology and in vitro melanin production. Among them, 15 isolates were selected

    Full Text Available As características específicas das chuvas variam entre regiões, e o conhecimento da sua potencialidade em causar erosão é necessário para planejar atividades agrícolas e de engenharia civil. Para a localidade de Rio Grande (RS, foi determinada a erosividade e sua relação com a precipitação e o coeficiente de chuva, os padrões hidrológicos e o período de retorno das chuvas. Utilizaram-se dados pluviográficos de 23 anos de Rio Grande. Para cada chuva erosiva, foram separados os segmentos do pluviograma com a mesma intensidade e registrados os dados em planilha. Com o programa Chuveros foram calculados a erosividade mensal, anual e média pelo índice EI30 no Sistema Internacional de Unidades e os padrões hidrológicos das chuvas. Os valores médios mensais da precipitação e do índice de erosividade foram expressos como percentagens do valor médio anual da precipitação e do índice de erosividade, respectivamente, a fim de obter a curva de distribuição acumulada da precipitação e do índice de erosividade em função do tempo. O coeficiente de chuva (Rc foi calculado. Foram realizadas correlações de Pearson e regressões lineares simples entre o índice de erosividade EI30 e os valores médios anuais de precipitação e de coeficiente de chuva. O período de retorno foi calculado para 2, 5, 10, 20, 50 e 100 anos. O valor médio anual da erosividade das chuvas com base no índice EI30 para o Rio Grande foi de 5.135 MJ mm ha-1 h-1, valor que representa o Fator "R" da Equação Universal de Perdas de Solo (USLE.

    Full Text Available We quantify uncertainty in the impacts of climate change on the discharge of the Rio Grande, a major tributary of the River Paraná in South America and one of the most important basins in Brazil for water supply and hydro-electric power generation. We consider uncertainty in climate projections associated with the SRES (greenhouse-gas emission scenarios (A1b, A2, B1, B2 and increases in global mean air temperature of 1 to 6 °C for the HadCM3 GCM as well as uncertainties related to GCM structure. For the latter, multimodel runs using 6 GCMs (CCCMA CGCM31, CSIRO Mk30, IPSL CM4, MPI ECHAM5, NCAR CCSM30, UKMO HadGEM1 and HadCM3 as baseline, for a + 2 °C increase in global mean temperature. Pattern-scaled GCM-outputs are applied to a large-scale hydrological model (MGB-IPH of the Rio Grande Basin. Based on simulations using HadCM3, mean annual river discharge increases, relative to the baseline period (1961–1990, by + 5% to + 10% under the SRES emissions scenarios and from + 8% to + 51% with prescribed increases in global mean air temperature of between 1 and 6 °C. Substantial uncertainty in projected changes to mean river discharge (− 28% to + 13% under the 2 °C warming scenario is, however, associated with the choice of GCM. We conclude that, in the case of the Rio Grande Basin, the most important source of uncertainty derives from the GCM rather than the emission scenario or the magnitude of rise in mean global temperature.

    In the 1960`s and 1970`s over 2500 bridges were built in the U.S. with a design similar to those on Interstate 40 over the Rio Grande in Albuquerque, New Mexico. These bridges were built without structural redundancy and typically have only two plate girders carrying the entire dead and live loads. Failure of either girder is assumed to produce catastrophic failure of the bridge, hence these bridges are referred to as fracture-critical bridges. The Federal Highway Administration (FHWA) and the National Science Foundation (NSF) have provided funds to New Mexico State University (NMSU) through the New Mexico State Highway and Transportation Department (NMSH&TD) and The Alliance For Transportation Research (ATR) for evaluation and testing of the existing fracture critical bridges over the Rio Grande. Because the 1-40 bridges over the Rio Grande were to be razed during the summer of 1993, the investigators were able to introduce simulated fatigue cracks, similar to those observed in the field, into the structure in order to test various damage identification methods and to observe the changes in load paths through the structure caused by the cracking. To support this research effort, NMSU contracted Los Alamos National Laboratory (LANL) to perform experimental modal analyses, and to develop experimentally verified numerical models of the bridge. Scientists from the LANL`s Condensed Matter and Thermal Physics Group (P-10) applied state-of-the-art sensors and data acquisition software to the modal tests. Engineers from the LANL`s Advanced Engineering Technology Group (MEE-13) conducted ambient and forced vibration tests to verify detailed and simplified finite element models of the bridge. Forced vibration testing was done in conjunction with engineers from Sandia National Laboratory (SNL) who provided and operated a hydraulic shaker.

    Full Text Available In 1938, Texas, New Mexico, and Colorado signed the Rio Grande Compact, establishing terms of apportionment for some of the water from the Rio Grande for the three states. Following congressional approval in 1939, this compact governs water allocation in a region with a variable climate and frequent drought conditions and established the Rio Grande Compact Commission, comprised of a commissioner from each state and one from the federal government, to enforce the compact. With an increasing population and declining surface water supply, the Compact has been tested among the parties and within the states themselves. In a case currently before the U.S. Supreme Court, Texas v. New Mexico and Colorado (2013, Texas claims New Mexico is violating the Compact and Rio Grande Project Act by using water in excess of its apportionment through its allowance of diversions of surface and groundwater. The issue is further compounded by disputes within Texas over separate legal regimes for groundwater and surface water. Combined with growing scarcity issues, the allocation of water in the Lower Rio Grande presents a timely natural resource challenge. This review explores legal issues involved in the case as well as growing challenges of population growth, agricultural development needs, and water shortages.

    Full Text Available This paper aims to describe how companies have managed the environmental issues, which kind of instruments are used for this purpose, comparing companies from the state of Rio Grande do Sul and the rest of Brazil. This work was developed using data published by Análise Editorial magazine about the environmental management practices that have been used by Brazilian companies. Data was obtained from the seventh edition of the yearbook Análise da Gestão Ambiental, which includes 853 companies, 25 banks and 237 non-governmental organizations (NGOs and 28 different economy branches. The research nature is classified as applied or technological; the approach method is quantitative; and, the study has a descriptive porpouse, since it exposes the characteristics of different companies; using literature and secondary data. The results point to the use of ISO 14001 as the main tool for environmental management and a lag of local companies. It may be asserted that other Brazilian companies are in an advanced stage regarding the environmental management practices compared to companies from Rio Grande do Sul.

    Full Text Available This study aims to identify, describe, and analyze the main links of the marine shrimp culture production chain in the extreme south of Brazil, specifically in the Rio Grande and São José do Norte municipalities, Rio Grande do Sul state. The research was carried out through prior bibliographic, in loco research and the application of interviews and questionnaires to identify the entire local productive process from the inputs needed for production to the arrival at the final consumer. The results indicate that the production chain requires actions in the process until the product’s final commercialization. Even as a growing market in Brazil, more investments, better support from the Government for the installation of new farmers, a reduction of bureaucracy in public agencies, training of actors involved in production, and some other points identified in this study can help decision makers, inherent to the activity, to establish sustainable production strategies aimed at lasting and full development of local shrimp production.

  2. Morphodynamics of a gravel-dominated macrotidal estuary: Rio Grande, Tierra del Fuego

    2004-06-01

    Full Text Available Rio Grande city (Tierra del Fuego is located on two attached beach systems, one of Upper Pleistocene (Sangamonian and the other of Holocene age. Both gravel spits grew from north to south modifying the inlet of the Rio Grande estuary. The present estuary is constrained by the modern and recurved spit Popper Spit. The main characteristic of this macrotidal estuary is that both margins and the bottom are mainly composed of rounded gravel. Expansion of the city is limited by oceanic and estuarine coasts, and is taking place towards salt marshes taking up more than 30 hectares in the last 20 years. The alteration of the tidal prism induced by marsh reclamation and the construction of a bridge may be affecting the inlet dynamics. The area of salt marsh and gravel banks were calculated by means of supervised classifications derived from a Landsat TM image. The inlet morphology changes in response to cycles dominated by longshore drift, wave refraction and ebb-tidal delta configuration. Oceanic beaches are characterised by large disc-shape boulders at the storm berm, spherical pebbles and sand runs at the foreshore, and fine sand on the low-tide terrace. Although tidal effects are very significant in the dynamics of the estuary, wind can prevail during some days or during slack water.

    Full Text Available Information on the breeding biology of birds is essential for improving avian life-history theory and implementing sound management and conservation actions for these organisms. Comprehensive reviews of this kind of information are lacking for most Neotropical regions, including Rio Grande do Sul, the southernmost Brazilian state. Aiming to update the knowledge on the reproductive status of birds in Rio Grande do Sul, we reviewed breeding records of all potential breeding species recorded in the state using a set of predefined, restrictive criteria for accepting breeding evidences as effective. Data satisfying our criteria were available for 165 species in the literature. We also collected novel breeding information obtained in the state for an additional 126 species, including observations for several species whose reproductive biology is poorly known. Among these are birds previously unknown to breed in Brazil. This new data and the critical review of the previous information resulted in a total of 291 species for which breeding evidences are accepted as effective. This corresponds to 54.7% of the 532 species considered either confirmed or potential breeders in the state. In addition to providing information on nesting dates, clutch size, nest architecture and breeding behavior of south Brazilian birds, our review serves as a benchmark for the adequate assessment of avian breeding records elsewhere. We hope to stimulate observers to rigorously document breeding events, especially for taxa for which basic information is lacking.

    Paracoccidioides brasiliensis is the etiological agent of the major systemic mycosis in Brazil, called paracoccidioidomycosis. Although the Rio Grande do Sul is considered an endemic area of the disease, there are few studies on the ecology of P. brasiliensis in the state. Therefore, this study aimed to evaluate the infection of P. brasiliensis in horses from the mesoregion of Southwest Riograndense, using these animals as sentinels. Serological techniques, such as double immunodiffusion in agar gel (AGID) and indirect ELISA, were performed to detect the anti-gp43 P. brasiliensis antibody in horses from five different farms in the region of Bagé, RS, Brazil. Serology was performed in 200 Pure Blood English horses up to two years of age that were born and raised exclusively at the farms. Of these horses, 12% had anti-gp43 antibodies according to the ELISA results, with rates ranging from 0 to 30% according to the farm of origin (p < 0.001). Based on the immunodiffusion results, all equine serum samples were negative. These results indicate the presence of the fungus P. brasiliensis in the middle region of the southwestern state of Rio Grande do Sul, Brazil. PMID:26273267

    Many basin-bounding faults in the Rio Grande rift show clear evidence of middle to late Pleistocene or Holocene motion. This study integrates published information and some of the authors unpublished data for the Rio Grande rift from West Texas to the Colorado/New Mexico border into detailed quantitative estimates of probabilistic seismic hazard for the rift. Published fault slip-rate, and slip rate calculated from published offsets, were compiled for input to a probabilistic hazard model. Fault segment length (L) was used to calculate moment release (M[sub 0]) from the relation derived by Wesnousky [1986]; M[sub 0] = 16.75 + 1.73 L. From the moment release and the moment accumulation rate (slip-rate) the average recurrence intervals were calculated. Finally, maximum horizontal ground acceleration was calculated from the study by Joyner and Furmal [1985]. Probability of exceedence of 0.1 g in 100 years was calculated on a 10 km grid for the rift. The reported probabilities should be viewed as minimum probabilities since (1) it is more difficult to determine slip rates on strike-slip cross-rift faults such as the Jornada and Embudo faults then it is to determine rates for vertical offset faults, and (2) this study only includes recognized active faults and identification of additional faults will increase the hazard in many areas. In some areas where multiple faults have been modelled individually, the faults may actually interact resulting in an overall lower seismic hazard.

  8. Influence of upwelling saline groundwater on iron and manganese cycling in the Rio Grande floodplain aquifer

    International Nuclear Information System (INIS)

    Salinity contributions from upwelling groundwater significantly degrade water quality in the Rio Grande, a major source of water for the southwestern USA. This study considers the influence of this upwelling water on the geochemistry and microbiology of the Rio Grande floodplain alluvial aquifer. The composition of surface water, groundwater, and floodplain sediment samples collected from three transects in the Socorro Basin was examined. Terminal-restriction fragment length polymorphism (T-RFLP) was also used to examine microbial biomass samples. The distribution of salinity in the floodplain groundwater largely reflects the configuration of local groundwater flow and mixing of two major water sources, deeply-sourced saline groundwater and river water. Microbial populations in the shallow aquifer consume O2 and NO3- and serve to redistribute metal oxides from the saturated zone to locations of groundwater discharge at the surface and possibly near the water table. The upwelling saline groundwater affects floodplain microbial processes by transporting reduced metals and organic electron donors to the alluvial aquifer system. This enhances metal reduction in the saturated zone and ultimately metal oxidation at or near the surface. Geochemical modeling suggests that mixing of the saline groundwater with more dilute water in the floodplain creates conditions more favorable for metal oxidation to occur and thereby influences the distribution of metal oxides

  9. Major and trace elements assessment in sediment samples from Rio Grande Reservoir, by neutron activation analysis

    International Nuclear Information System (INIS)

    The Rio Grande Reservoir, Southeast of the Sao Paulo Metropolitan Area (SPMA) supplies water for four counties (Sao Bernardo do Campo, Sao Caetano do Sul, Santo Andre and Diadema). It has been seriously affected by urban expansion, due to chaotic urban occupation and improper use of the surrounding areas. In this study bottom sediment samples were collected, by using a Van Veen sampler, during the dry and rainy seasons. Four sampling points were defined by using GPS and are located at the mouth of the Rio Grande and Ribeirao Pires Rivers, in the middle of the reservoir and near the catchment point of the water supply. The sediment samples were submitted to instrumental neutron activation analysis (INAA) and the following elements were determined: As, Ba, Br, Co, Cr, Cs, Rb, Sb, Sc, Se, Ta, Th, U e Zn and the rare earth elements Ce, Eu, La, Lu, Nd, Sm, Tb, Yb. Short irradiation was also performed for total Hg determination by NAA using 197Hg radioisotope. This was possible due to the high Hg concentration levels in these sediments. The methodology validation was carried out by certified reference material analyses. The results obtained for multielemental concentrations in the sediment samples were compared to NASC (North American Shale Composite) values. The concentration values obtained for As and metals Cr, Hg and Zn in the sediment samples were compared to the Canadian Council of Minister of the Environment (CCME) oriented values (TEL and PEL values) and adopted by CETESB.

    This study aimed to determine the prevalence of acute lower respiratory illness and to identify associated factors among children less than five years of age in the city of Rio Grande, southern Brazil. Using a cross-sectional survey, a standardized household questionnaire was applied to mothers or guardians. Information was collected on household conditions, socioeconomic status, and parental smoking. Prenatal care attendance, nutritional status, breastfeeding pattern, and use of health services for the children were also investigated. Data analysis was based on prevalence ratios and logistic regression, using a conceptual framework. Among 771 children studied, 23.9% presented acute lower respiratory illness. The main risk factors were previous episodes of acute lower respiratory infection or wheezing, crowding, maternal schooling less than five years, monthly family income less than US$ 200, four or more people per room, asthma in family members, and maternal smoking. Mothers 30 years or older were identified as a protective factor. These results can help define specific measures to reduce morbidity and mortality due to acute lower respiratory illness in this setting. PMID:18545768

    The Rio Grande is clearly undergoing salinization, manifested by a 50-fold increase in total dissolved solids content between its headwaters in Colorado and the U.S.-Mexico border. To elucidate the causes of this salinization, we conducted an eight-day synoptic sampling campaign in August 2001. This sampling included the river, its major tributaries, and major irrigation drain inflows. Along 1200 km between the river headwaters in Colorado and Fort Quitman, Texas, we collected 110 water samples with an average interval of ~10 km between sampling locales. In the laboratory, samples were analyzed for major constituents including chloride, as well as for bromide and the 36Cl/Cl ratio. Isotopic fingerprinting using the 36Cl/Cl ratio indicates that meteoric waters and deep sedimentary brines respectively account for most of the water and most of the salt inflow to the Rio Grande. The meteoric end member has a 36Cl/Cl ratio of 1100 and a Cl/Br ratio of 30; the brine end member has a 36Cl/Cl ratio of 35 and a Cl/Br ratio of 1150. Using these end member chemistries with USGS stream flow gauging data, we constructed a water- and salt- instantaneous mass balance model of the Rio Grande for the eight-day sampling interval. This model indicates that most water losses from the Rio Grande are due to evaporation from Elephant Butte reservoir, open water evaporation from irrigation ditches, and evapotranspiration of riparian and ditch-bank vegetation. The model also emphasizes the significance of salt input due to deep brine discharge to the river, particularly at the downstream ends of local sedimentary basins of the Rio Grande rift. The Rio Grande receives a smaller amount of salt from saline drains near El Paso, which may be acquiring salt from deep brine discharge as they cross over faults or other structural fluid conduits.

    Full Text Available O objetivo deste trabalho foi avaliar os impactos ambientais do manejo agroecológico da caatinga, em unidades de produção familiar no Rio Grande do Norte, pelo método Ambitec de produção animal - dimensão ambiental, desenvolvido pela Embrapa Meio Ambiente. Foram avaliadas sete unidades de produção familiar, em quatro projetos de assentamentos de reforma agrária do Município de Apodi, RN. Os dados para o levantamento foram obtidos por meio de questionários aplicados aos representantes das unidades produtivas familiares, que atribuíram, a cada variável estudada, um valor que representou a alteração proporcionada pela implementação da tecnologia. Após a inserção dos coeficientes de alteração de cada variável dos indicadores por unidade de produção, o coeficiente de impacto foi automaticamente calculado por meio da planilha Ambitec. O manejo agroecológico da caatinga resultou num impacto ambiental positivo, e suas maiores contribuições foram relacionadas aos efeitos positivos dos seguintes indicadores: capacidade produtiva do solo, uso de insumos materiais, qualidade do produto e diminuição da emissão de poluentes à atmosfera. Dois indicadores geraram efeitos negativos: o uso de energia e o uso de recursos naturais. Pela superioridade dos benefícios gerados, o manejo agroecológico da caatinga é uma inovação tecnológica geradora de impactos ambientais positivos.The objective of this work was to evaluate the environmental impacts of caatinga agroecological handling, in production unities of family farms, in Rio Grande do Norte, using the method Ambitec of animal production - environmental dimension, developed by Embrapa Meio Ambiente.

  1. Determining Environmental Factors Controlling Nitrogen Cycling in the Semi-Arid Rio Grande Using Nitrogen and Oxygen Isotopes

    The Rio Grande is a semi-arid river in the American Southwest supporting agriculture and large populous centers in New Mexico and west Texas. In addition to increasing salinity, considerable increases of nitrate (NO3), up to ~50 mg/L, have been previously observed in the Rio Grande between Las Cruces, New Mexico and El Paso, Texas. This is particularly a problem during non-irrigation season when little surface water is released from upstream reservoirs, substantially reducing stream flows in the Rio Grande. While both irrigation runoff and municipal waste effluents are likely important NO3 contributors, there are no quantitative studies assessing NO3 fluxes to the Rio Grande from these two sources. Therefore, in this study we used 𝛿15N and 𝛿18O values of NO3 as environmental tracers to characterize major NO3 sources in the Rio Grande and its agricultural drains between Las Cruces and El Paso. Surface water of the semi-arid Rio Grande, drains and major wastewater treatment plants were collected in October 2014 (non-irrigation season) and August 2015 (irrigation season). The water samples from the 2014 sampling campaign showed that the 𝛿15N and 𝛿18O values of NO3 in the Rio Grande and two agricultural drains located south of El Paso varied in relatively narrow range from +9.8 to +15.7‰ and -5.9 to -0.2‰, respectively. These ranges were similar to 𝛿15N and 𝛿18O values of local wastewater treatment plants in Las Cruces and El Paso, from +8.2 to +10.2‰ and -9.7 to -2.5‰ respectively. Municipal wastewater effluents are important tributaries to the semi-arid Rio Grande in the studied area, particularly during non-irrigation season. Furthermore, irrigation of agricultural fields south of El Paso is to a large extent supported by reclaimed municipal wastewater. Consequently, these explain the observed higher contributions of NO3 from urban sources in the investigated area.

    The Lower Rio Grande Valley (LRGV) of southern Texas is located on the United States-Mexico borderland and represents a 240-kilometer (150-mile) linear stretch that ends at the Gulf of Mexico. The LRGV represents a unique transition between temperate and tropical conditions and, as such, sustains an exceptionally high diversity of plants and animals—some of them found in few, or no other, places in the United States. Examples include Leopardus pardalis albescens (northern ocelot) and Falco femoralis septentrionalis (northern aplomado falcon)—both endangered in the United States and emblematic of the LRGV. The U.S. Fish and Wildlife Service (USFWS) manages three national wildlife refuges (Santa Ana, Lower Rio Grande Valley, and Laguna Atascosa) that together make up the South Texas Refuge Complex, which actively conserves biodiversity in about 76,006 hectares (187,815.5 acres) of native riparian and upland habitats in the LRGV. These diminished habitats harbor many rare, threatened, and endangered species. This report updates the widely used 1988 USFWS biological report titled “Tamaulipan Brushland of the Lower Rio Grande Valley of South Texas: Description, Human Impacts, and Management Options” by synthesizing nearly 400 peer-reviewed scientific publications that have resulted from biological and sociological research conducted specifically in the four Texas counties of the LRGV in the past nearly 30 years. This report has three goals: (1) synthesize scientific insights gained since 1988 related to the biology and management of the LRGV and its unique biota, focusing on flora and fauna of greatest conservation concern; (2) update ongoing challenges facing Federal and State agencies and organizations that focus on conservation or key natural resources in the LRGV; and (3) redefine conservation opportunities and land-acquisition strategies that are feasible and appropriate today, given the many new and expanding constraints that challenge conservation

    Full Text Available This study evaluates the effects of agricultural and urban activities on the structure and composition of benthic communities of streams in the state of Rio Grande do Sul, Brazil. Benthic macroinvertebrates were collected in streams influenced by urbanization and agriculture and in streams with no anthropogenic disturbances (reference streams. Organism density was superior in urban streams when compared with streams in the other two areas. The taxonomic richness and Shannon diversity index were higher in reference streams. The benthic fauna composition was significantly different among land uses. The classification and ordination analyses corroborated the results of variance analyses demonstrating the formation of clusters corresponding to streams with similar land use. Seasonality was also found to influence the benthic community, though in a lesser degree than land use.

    Full Text Available A two-month-old lamb showing signs of severe neurological disease characterized by muscular tremors, hypermetria, and motor incoordination was submitted to the Veterinary Pathology Laboratory - Universidade Federal do Rio Grande do Sul, Brazil. At necropsy, the major findings were a marked reduction of the size of the cerebellum and bilateral dilatation of the lateral ventricles. Microscopically, areas of cellular disorganization in the cerebellar cortex, reduction of the granular layer of cerebellum associated with decreased density of cells, and the presence of large cytoplasmic vacuoles in the molecular layer were observed. Neurons of the gray matter of the brain and macrophages of the mesenteric lymph nodes stained positively by the immunohistochemistry test using the monoclonal antibody 15C5 against Bovine Viral Diarrhea Virus. Taken together, those results are consistent with a pestivirus infection, either Border Disease Virus (BDV or BVDV.

    Full Text Available Canine atopic dermatitis (CAD is a common dermatosis, defined as a genetic-related disease which predisposes to skin inflammation and pruritus, associated to a IgE-specific response in most of cases. Clinical diagnosis may be later complemented by skin allergy and/or serological tests. The aim of these tests is to identify possible allergens in order to enable the clinicians to select candidate antigens for allergen specific immunotherapy. In the present study 58 CAD positive animals were tested. All were submitted to the intradermal test (IDT and screened for the presence of antibodies against different antigens using ELISA. The obtained results show a high prevalence of sensitization among the tested dogs to house dust mites and to pollen ofC. dactylon. With this work it was possible to identify the main allergens involved in immunological response of dogs with CAD living in central area of Rio Grande do Sul.

    International Nuclear Information System (INIS)

    The application of montmorillonite nano composites has been improved in order to obtain dispersed phase with particles of nano metric dimensions. To obtain these nanoparticles, the clays must pass an effective purification process for removing unwanted materials, which would undermine the processes of intercalation and exfoliation of montmorillonite in a polymer matrix. This study intention to characterize and purify a montmorillonite clay from deposit recently discovered in the city of Parelhas in Rio Grande do Norte, through the separation of coarser materials by decantation followed by a chemical attack that promoted oxidation in samples where it was realized reduction of impurities such as organic matter and other substances that would hinder the achievement of nanoparticles. Under these conditions, the clay is suitable for the work as dispersed phase in a polymer matrix nano composite. The results were demonstrated by analysis of scanning electron microscopy (SEM), chemical analysis, BET and X-ray diffraction (XRD). (author)

    Full Text Available The main goal of this study is to understand and analyse the perspective of dockworkers on health and labour at the Railway Dry Port of the Municipality of Uruguaiana in the State of Rio Grande do Sul (RS, Brazil. Sixteen dockworkers participated in the study under the methodological approach of qualitative research. The fieldwork was conducted through individual interviews by applying a semi-structured research script with open-ended questions. For the data analysis, the "discourse analysis" method was adopted, leading to the definition of five thematic categories of interpretation. From the perspective of dockworkers, dock work differs in both the weight of toil, which is hard and intense, and the sense of satisfaction regarding the collaborative and collective aspect of labour, emphasising the human side of labour. Several reports on work accidents and the identification of hazards that may be avoided by implementing changes in the organisation and work conditions were also noted.

    Full Text Available OBJECTIVES: Information on the prevalence and concomitants of arthritis in developing countries is sparse. It is unclear whether they are comparable to findings in developed countries. To ascertain the prevalence, demographic characteristics, and health-related concomitants of arthritis in older persons in the southern state of Rio Grande do Sul, Brazil, a middle income country. METHODS: The state of Rio Grande do Sul, Brazil, was subdivided into nine regions. Stratified random sampling was used to identify 880 community residents age ≥60 years in each region. One region with suspect data was excluded. Of 7040 community residents contacted in eight regions, 6963 participated (1.1% refusal rate. In 1995, trained, monitored interviewers, using structured questionnaires, conducted in-home interviews gathering information on demographic characteristics (age, sex, race/ethnicity, education, income, living arrangements, employment status, health behaviors (physical activity, tobacco use, social activity, functional limitations, depression, and 15 self-reported health conditions, including arthritis. Data were analyzed using descriptive statistics and logistic regression. RESULTS: Arthritis, reported by 43% of the sample, was more prevalent in women, among the less educated, those with lower income, and higher age. Severity, but not prevalence, differed by race/ethnicity. Controlled analyses indicated significant association with female gender, lower education, and less social activity. Arthritis was associated with reduced odds of stroke, but increased odds of hypertension, varicosities, bronchitis, renal problems, headache, gastrointestinal disorders, and depression. Arthritis was not significantly associated with age or functional limitations, and associations did not differ by gender. CONCLUSIONS: The prevalence, demographic and health characteristics associated with self-reported arthritis in this southern state in Brazil are similar to findings

    Toledo, the southernmost district, is the hub of Belize's Mayan population, descendants of the ancient Mayan civilization. The Toledo District is primarily inhibited by Kekchi and Mopan Mayans whose subsistence needs are met by the Milpa slash-and-burn agricultural system and the extraction of forest resources. The poverty assessment in the country indicates that Toledo is the district with the highest percentage of household an individual indigence of 37.5 % and 49.7 % respectively. Forest cover change in the area can be attributed to rapid population growth among the Maya, together with increase in immigration from neighboring countries, logging, oil exploration and improvement and construction of roads. The forest cover change analysis show that from 2001 to 2011 there was a decrease of Lowland broad-leaved wet forest of 7.53 km sq, Shrubland of 4.66 km sq, and Wetland of 0.08 km sq. Forest cover change has resulted in soil erosion which is causing the deterioration of soils. The land cover types that are contributing the most to total erosion in the Rio Grande watershed are no-forest, lowland broad-leaved wet forest and submontane broad-leaved wet forest. In this study the Revised Universal Soil Loss Equation (RUSLE) was employed in a GIS platform to quantify and assess forest cover change and soil erosion. Soil erosion vulnerability maps in Toledo's Rio Grande watershed were also created. This study provides scientifically sound information in order to understand and respond effectively to the impacts of soil erosion in the study site.

    Water quality often limits the potential uses of scarce water resources in semiarid and arid regions. To best manage water quality one must understand the sources and sinks of both solutes and water to the river system. Nutrient concentration patterns can identify source and sink locations, but cannot always determine biotic processes that affect nutrient concentrations. Modeling tools can provide insight into these large-scale processes. To address questions about large-scale nitrogen removal in the Middle Rio Grande, NM, we created a system dynamics nitrate model using an existing integrated surface water--groundwater model of the region to evaluate our conceptual models of uptake and denitrification as potential nitrate removal mechanisms. We modeled denitrification in groundwater as a first-order process dependent only on concentration and used a 5% denitrification rate. Uptake was assumed to be proportional to transpiration and was modeled as a percentage of the evapotranspiration calculated within the model multiplied by the nitrate concentration in the water being transpired. We modeled riparian uptake as 90% and agricultural uptake as 50% of the respective evapotranspiration rates. Using these removal rates, our model results suggest that riparian uptake, agricultural uptake and denitrification in groundwater are all needed to produce the observed nitrate concentrations in the groundwater, conveyance channels, and river as well as the seasonal concentration patterns. The model results indicate that a total of 497 metric tons of nitrate-N are removed from the Middle Rio Grande annually. Where river nitrate concentrations are low and there are no large nitrate sources, nitrate behaves nearly conservatively and riparian and agricultural uptake are the most important removal mechanisms. Downstream of a large wastewater nitrate source, denitrification and agricultural uptake were responsible for approximately 90% of the nitrogen removal.

    Transboundary zoonotic diseases, several of which are vector borne, can maintain a dynamic focus and have pathogens circulating in geographic regions encircling multiple geopolitical boundaries. Global change is intensifying transboundary problems, including the spatial variation of the risk and incidence of zoonotic diseases. The complexity of these challenges can be greater in areas where rivers delineate international boundaries and encompass transitions between ecozones. The Rio Grande serves as a natural border between the US State of Texas and the Mexican States of Chihuahua, Coahuila, Nuevo León, and Tamaulipas. Not only do millions of people live in this transboundary region, but also a substantial amount of goods and people pass through it everyday. Moreover, it occurs over a region that functions as a corridor for animal migrations, and thus links the Neotropic and Nearctic biogeographic zones, with the latter being a known foci of zoonotic diseases. However, the pathogenic landscape of important zoonotic diseases in the south Texas-Mexico transboundary region remains to be fully understood. An international perspective on the interplay between disease systems, ecosystem processes, land use, and human behaviors is applied here to analyze landscape and spatial features of Venezuelan equine encephalitis, Hantavirus disease, Lyme Borreliosis, Leptospirosis, Bartonellosis, Chagas disease, human Babesiosis, and Leishmaniasis. Surveillance systems following the One Health approach with a regional perspective will help identifying opportunities to mitigate the health burden of those diseases on human and animal populations. It is proposed that the Mexico-US border along the Rio Grande region be viewed as a continuum landscape where zoonotic pathogens circulate regardless of national borders. PMID:25453027

    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.

    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)

    The Atlantic Rain forest, which is considered the second largest pluvial forest in the American continent, has had an estimated 93% of its original area destroyed. Although studies concerning the herpetofaunal diversity in this biome have been intensified in the past years, its diversity is still underestimated. The Nucleo Experimental de Iguaba Grande (NEIG) is included in an Environmental Protection Area (APA de Sapeatiba) in the Iguaba Grande municipality, Rio de Janeiro state, Brazil (22º 51' S and 42º 10' W). The goal of this study was to conduct an inventory of the reptile and amphibian species that occur in this area between July 2008 and December 2009. We recorded 19 species of amphibians (18 anurans and one caecilian) and 15 species of reptiles (three lizards, 11 snakes and one amphisbaenian). Leptodactylus latrans and L. mystacinus had the highest capture rates among amphibians captured, and among reptiles, Ameiva ameiva, Hemidactylus mabouia and Mabuya agilis had the highest capture rates. Rarefaction curves for both amphibians and reptiles did not reach the asymptote, indicating that the species richness in the NEIG is still underestimated. PMID:22990826

    A sample of 255 Brazilian males from Rio Grande do Sul (RS), the Brazilian southernmost state, was typed for 17 Y-STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, YGATA_H4.1 and DYS385ab). A total of 247 haplotypes were identified, of which 239 were unique and eight were found in two individuals each. The haplotype diversity (99.98%) and discrimination capacity (96.86%) were calculated. Pairwise haplotype distances showed that the RS population is not significantly different from Brazil, Rio de Janeiro, and Argentina, is different from São Paulo, Italy, and North Portugal, and is very distant from Spain, the Amazon region, Germany, and South Amerindians. When the RS data was separated in the seven geopolitical regions, some pairs of regions were significantly different; however no region was different from the whole Brazilian sample. PMID:19948319

    Plummer, L. Niel; Bexfield, Laura M.; Anderholm, Scott K.; Sanford, Ward E.; Busenberg, Eurybiades

    Chemical and isotopic data for groundwater from throughout the Middle Rio Grande Basin, central New Mexico, USA, were used to identify and map groundwater flow from 12 sources of water to the basin, evaluate radiocarbon ages, and refine the conceptual model of the Santa Fe Group aquifer system. Hydrochemical zones, representing groundwater flow over thousands to tens of thousands of years, can be traced over large distances through the primarily siliciclastic aquifer system. The locations of the hydrochemical zones mostly reflect the ``modern'' predevelopment hydraulic-head distribution, but are inconsistent with a trough in predevelopment water levels in the west-central part of the basin, indicating that this trough is a transient rather than a long-term feature of the aquifer system. Radiocarbon ages adjusted for geochemical reactions, mixing, and evapotranspiration/dilution processes in the aquifer system were nearly identical to the unadjusted radiocarbon ages, and ranged from modern to more than 30 ka. Age gradients from piezometer nests ranged from 0.1 to 2 year cm-1 and indicate a recharge rate of about 3 cm year-1 for recharge along the eastern mountain front and infiltration from the Rio Grande near Albuquerque. There has been appreciably less recharge along the eastern mountain front north and south of Albuquerque. Des données sur les éléments chimiques et les isotopes présents dans l'eau souterraine prélevée à divers endroits dans le bassin moyen du Rio Grande, au centre du Nouveau-Mexique (É-U), ont permis de déterminer l'existence et l'étendue de douze sources d'eau régionales dans le bassin, d'évaluer les âges radiocarbones et de raffiner le modèle conceptuel du système aquifère du groupe de Santa Fe. Des zones hydro-chimiques qui représentent l'écoulement de l'eau souterraine depuis des dizaines de milliers d'années peuvent être suivies sur de longues distances à travers l'aquifère principalement siliclastique.

    Peridotite xenoliths from the Rio Grande Rift (RGR) are being analyzed for H (sub 2) O contents by FTIR (Fourier Transform Infrared) as well as for major and trace element compositions. Nine samples are from the Rio Puerco Volcanic Field (RP) which overlaps the central RGR and southeastern Colorado Plateau; seventeen samples are from Kilbourne Hole (KH) in the southern RGR. Spinel Cr# (Cr/(Cr+Al)) (0.08-0.46) and olivine Mg# (Mg/(Mg plus Fe)) (0.883-0.911) of all RGR samples fall within the olivine-spinel mantle array from [1], an indicator that peridotites are residues of partial melting. Pyroxene H (sub 2) O in KH correlate with bulk rock and pyroxene Al (sub 2) O (sub 3).The KH clinopyroxene rare earth element (REE) variations fit models of 0-13 percent fractional melting of a primitive upper mantle. Most KH peridotites have bulk-rock light REE depleted patterns, but five are enriched in light REEs consistent with metasomatism. Variation in H (sub 2) O content is unrelated to REE enrichment. Metasomatism is seen in RP pyroxenite xenoliths [2] and will be examined in the peridotites studied here. Olivine H (sub 2) O contents are low (less than or equal to 15 parts per million), and decrease from core to rim within grains. This is likely due to H loss during xenolith transport by the host magma [3]. Diffusion models of H suggest that mantle H (sub 2) O contents are still preserved in cores of KH olivine, but not RP olivine. The average H (sub 2) O content of Colorado Plateau clinopyroxene (670 parts per million) [4] is approximately 300 parts per million higher than RGR clinopyroxene (350 parts per million). This upholds the hypothesis that hydration-induced lithospheric melting occurred during flat-slab subduction of the Farallon plate [5]. Numerical models indicate hydration via slab fluids is possible beneath the plateau, approximately 600 kilometers from the paleo-trench, but less likely approximately 850 kilometers away beneath the rift [6].

    Full Text Available Na região sul do Rio Grande do Sul a infestação dos bovinos por Rhipicephalus (Boophilus microplus ocorre, principalmente, entre os meses de outubro e abril, devido às condições climáticas. Além do conhecimento do ciclo biológico desse parasito, também é fundamental conhecer a epidemiologia, para estabelecer estratégias de controle. No Rio Grande do Sul, e também no Brasil, existem poucos estudos epidemiológicos a respeito da resistência aos acaricidas. Além disso, a grande área geográfica e a deficiência estrutural quanto ao uso e acesso a bancos de dados dificultam a obtenção de dados confiáveis. O presente estudo teve como objetivo realizar um inquérito abordando a percepção dos produtores da região sul do Rio Grande do Sul, quanto à identificação de populações de R. (B. microplus difíceis de controlar com acaricidas e os fatores de risco para a seleção de populações de carrapatos resistentes. Para execução do trabalho foram coletados dados sobre o controle do carrapato de bovinos de corte, em 85 propriedades de sete municípios, localizados na região sul do Estado. Os resultados revelaram a existência de associação positiva entre a dificuldade de controlar o carrapato com os acaricidas e o grau de instrução do proprietário (até o ensino fundamental com OR=3,67 e p=0,01 e o número de aplicação de carrapaticida por ano (superior a 4 com OR=4,05 e p=0,006. Esses resultados indicam também que propriedades com mais de 100 bovinos de corte em criação extensiva, na região sul do rio Grande do Sul apresentam características que podem contribuir para uma maior vida útil dos carrapaticidas do que as verificadas em outras regiões do País.In the southern region of Rio Grande do Sul, cattle become infested with Rhipicephalus (B. microplus mainly between October and April due to the climatic conditions.

    Full Text Available O presente artigo, com base nas folhas de pagamentos dos professores das redes públicas estaduais do Rio Grande do Sul (RS e de São Paulo (SP, mostra que a remuneração dos professores das redes públicas destes estados não está relacionada com o desempenho dos professores, sendo o tempo de serviço o fator determinante na evolução da remuneração. O salário relativo médio de um professor da rede dos estados do Rio Grande do Sul e de São Paulo, como fração do PIB, é superior ao encontrado em outros países que são considerados exemplos de bom desempenho escolar. Ou seja, não há evidência de que o salário nestas redes esteja fora da nor-ma tomando como comparação os países da OECD. O artigo mostra, ainda, que o salário médio pago aos professores da ativa é inferior ao benefício médio concedido aos inativos e que estes apresentam um elevado custo na folha de pagamentos dos estados, superior aos 50% no Rio Grande do Sul e 35% em São Paulo. Mais, as regras para aposentadoria dos professores no Brasil são extremamente generosas quando comparadas com outros países do mundo.

    Full Text Available É no contexto do pós-Estado Novo, quando o revisionismo toma conta da produção historiográfica sul-rio-grandense, que os escritos de Gilberto Freyre obtêm maior repercussão entre a intelectualidade sulina. O artigo detém-se sobre as motivações desse alinhamento tardio com as opções analíticas do autor recifense. Em um momento marcado pela ascensão das ciências sociais e pela perda de autoridade das narrativas históricas até então centradas no papel integrador dos heróis militares, historiadores e críticos locais atuam conjuntamente em favor da reversão dos motivos que apartavam a produção textual da "província" dos temas em voga no centro do país. Nesse passo, fez-se mister a aproximação da História com o Folclore, este apreendido não mais como um ramo da filologia ou do regionalismo literário, mas sob um viés "sociológico".The period in the wake of the Novo Estado (New State, when revisionism took hold of historiographic production in Rio Grande do Sul, provided the context for the writings of Gilberto Freyre to acquire a greater influence among the southern intelligentsia. The article investigates the reasons for this delayed alignment with the analytic model of the Recife author. At a time marked by the rise of the social sciences and the loss in authority of historical narratives centred on the integrating role of military heroes, local historians and critics combined forces to reverse the motivating factors that had previously separated the textual production of the ‘province’ from the themes in fashion in the intellectual ‘centre’ of Brazil (Rio de Janeiro and São Paulo. This step required closing the gap between History and Folklore, meaning the latter was no longer apprehended as a branch of philology or literary regionalism, but as an area of study to be approached from a ‘sociological’ angle.

    The segment of the Rio Grande between International Falcon Reservoir and Del Rio, Texas (distance ca. 350 km), remains largely unexplored ornithologically. We surveyed nocturnal birds monthly during February-June 1998 at 19 stations along the Rio Grande (n = 6) and at upland stock ponds (n = 13) in Webb County, Texas. We conducted 10-min point counts (n = 89) after sunset and before moonset. Four species of owls and five species of nightjars were detected. Nightjars, as a group, were nearly five limes more abundant (mean number/count = 2.63) than owls (mean number = 0.55). The most, common owl, the great horned owl (Bubo virginianus), had a mean number of 0.25/point count. The mean for elf owls (Micrathene whitneyi) was 0.16/point count. The most common nightjars were the common poorwill (Phalaenoptilus nuttallii; 1.21/point count) and lesser nighthawk (Chordeiles acutipennir, 1.16/point count). Survey sites on the river supported more species (mean = 2.2) than did upland stock ponds (mean = 1.4). However, only one species (common pauraque, Nyctidromus albicollis) showed a preference for the river sites. Our results establish this segment of the Rio Grande in southern Texas as an area of high diversity of nightjars in the United States, matched (in numbers of species) only by southeastern Arizona and southwestern New Mexico.

    Since 1950 demand for water has more than doubled in the United States. Virtually all water supplies are allocated, leading to the question, where will water come from? The concept of water leasing has gained considerable attention as a volunteer, market-mediated system for transferring water between competing uses. For a water leasing system to be truly effective, detailed knowledge of the available water supply and the factors that affect water demand is critical. Improving understating of the factors that determine residential, industrial, and agricultural demand for water using experimental economics and then integrating with a hydrological model will allow for better understanding of market-based mechanisms potential to allocate water resources effectively. Currently we have three case studies underway, a generalized water leasing system on the Middle Rio Grande, a sophisticated farmer decision process and a study in the Mimbres basin in southern New Mexico. The developed market model utilizes an open market trading system known as a double auction, where buyers and sellers declare their bids and offers to the market. The developed hydrological model utilizes the Upper Rio Grande Water Operations Model (URGWOM) system structure and data for the generalized water leasing system and the farmer decision process, with a different hydrological model being developed for the Mimbres basin. A key coupling between the hydrologic and market models involves tracking the difference in river losses for trades that move water up or down the river. In the experiments the hydrological model runs before the market-trading period to establish water rights, the trading period occurs and the hydrological model then runs a second time to report flows to each reach of the river. Participants in the experiment represent the interests of specific users, including farmers, Native American interests, urban interests and environmental interests. Participants in the experiments are

    Full Text Available Paleomagnetic and rockmagnetic data are reported for the aeolian Botucatu Formation, in the southern Brazilian State of Rio Grande do Sul. Oriented samples were taken from a section located between the cities of Jaguari and Santiago. After thermal and alternating field demagnetization, both normal and reversed characteristic remanent magnetizations were found. These results yielded 13 reversed and 5 normal polarity sites, composing a magnetostratigraphic column displaying a sequence of reversed-normal-reversed polarity events. The paleomagnetic pole calculated for 18 sites is located at 114.7ºE, 78.5ºS (dp=8.1º; dm=1.2º, after restoring the strata to the paleohorizontal. This paleomagnetic pole indicates a Late Jurassic-Early Cretaceous age to the Botucatu Formation in the investigated area, and places the sampling sites at paleolatitudes as low as 21ºS.Dados paleomagnéticos e de magnetismo de rochas dos sedimentos eólicos da Formação Botucatu, no Estado do Rio Grande do Sul, obtidos de uma seção localizada entre as cidades de Jaguari e Santiago, permitiram definir a idade dessa formação.

    1993-01-01

    The tectonic response of the Taos Plateau volcanic field in the southern San Luis basin to the late stage extensional environment of the Rio Grande rift was investigated using paleomagnetic techniques. Sixty-two sites (533 samples) of Pliocene volcanic units were collected covering four major rock types with ages of 4.7 to 1.8 Ma. Twenty-two of these sites were from stratigraphic sections of the lower, middle and upper Servilleta Basalt collected in the Rio Grande gorge at two locations 19 km apart. Flows from the lower and middle members in the southern gorge record reversed polarities, while those in Garapata Canyon are normal with an excursion event in the middle of the sequence. The uppermost flows of the upper member at both sites display normal directions. Although these sections correlate chemically, they seem to represent different magnetic time periods during the Gilbert Reversed-Polarity Chiron. Alternating field demagnetization, aided by principal component analysis, yields 55 sites with stable directions representing both normal and reversed polarities, and five sites indicating transitional fields. Mean direction of the normal and inverted reversed sites is I=49.3 deg. and D=356.7 deg. (alpha(sub 95)=3.6 deg). Angular dispersion of the virtual geomagnetic poles is 16.3 deg, which is consistent with paleosecular variation model G, fit to data from the past 5 m.y. Comparison with the expected direction indicates no azimuthal rotation of the Taos Plateau volcanic field; inclination flattening for the southern part of the plateau is 8.3 deg +/- 5.3 deg. Previous paleomagnelic data indicate 10 deg- 15 deg counterclockwise rotation of die Espanola block to the south over the past 5 m.y. The data suggest the Taos Plateau volcanic field, showing no rotation and some flattening in the south and east, has acted as a stable buttress and has been downwarped by overriding of the southeastern end of the plateau by the Picuris Mountains, which make up the northern

    Full Text Available Esta revisão aborda a situação da piscicultura continental no Rio Grande do Sul nos últimos anos em termos de produção e problemas enfrentados pelo setor. Além disso, apresenta algumas perspectivas futuras para a piscicultura continental neste Estado. O Rio Grande do Sul contribui com uma boa porcentagem da produção brasileira de piscicultura continental, mas passa por um período de estagnação nos últimos anos. Há um predomínio muito grande de espécies de peixes exóticas na produção (principalmente carpas. A venda de peixes concentra-se no período que antecede à Páscoa e a fiscalização sanitária ainda é reduzida. Produtores estão iniciando a formação de cooperativas na região central do Rio Grande do Sul. A publicação de livros sobre cultivo de espécies nativas e a estagnação da produção pesqueira extrativa continental nos últimos anos pode favorecer a criação de espécies nativas, das quais várias são sugeridas nesta revisão. A criação de espécies nativas para venda como peixe ornamental ainda é uma opção a ser explorada no futuro pelos piscicultores deste Estado.This review deals with freshwater fish culture in Rio Grande do Sul State, southern Brazil, and analyzes production and problems of this activity in the last years. This State contributes with a good percentage of Brazilian freshwater fish culture, but its production has been stagnated in the last years. Production is based essentially on exotics fish species (mainly carps. Fish sales are concentrated in the Easter period, and sanitary inspection is still reduced. Fish farmers are making cooperatives in the central region of Rio Grande do Sul. The publishing of books of native species and the freshwater fisheries stagnation in the last years may stimulate the raise of native species, and some are suggested in this review. The culture of native species to be sold as ornamental fishes is still a future option for fish farmers of this State.

    Full Text Available Rural property owners open their doors to tourism for several reasons. In part it is due to the failure in achieving agricultural profits. Thus, receiving tourists can increase income, add value to the property, and diversify economic activity. On the other hand, agritourism and rural tourism create new opportunity which does not depend exclusively on agricultural production. Furthermore, this reflects a new agrarian reality, a transition from an ‘agricultural’ to a ‘rural’ economy.  The goal of this study is to identify the potential of rural properties in the southern of Rio Grande do Sul, Brazil, in order to develop agritourism and rural tourism as an economic alternative. More specifically, we propose to identify the characteristics of tourism activities at several properties and evaluate the economic viability, employment opportunities and salary growth between 1997 and 2006. There has been ongoing research in this area since 2006 and new studies are being carried out, especially regarding rural tourism property turnover, although they are not the object of the current study. The results of this study infer that the southern of the state presented unfavorable outcomes regarding income and job creation on the farms that practiced agritourism and rural tourism. Current trends emphatically focus on these kinds of tourism as alternatives for developing the services sector in the Southern Half rural areas and, while there is visible potential, it is necessary to develop projects and procure the participation of the government and private sector in order to make tourism in rural areas more effective. There are many activities that can be carried out, such as promoting events and attempting to change the mentality related to living in the rural areas as well as the good use of the properties in order to create a new framework. Evolução do Turismo na Área Rural do Sul do Rio Grande do Sul - Os proprietários rurais abrem suas portas ao

    Water resource scarcity around the world is driving the need for the development of simulation models that can assist in water resources management. Transboundary water resources are receiving special attention because of the potential for conflict over scarce shared water resources. The Rio Grande/Rio Bravo along the U.S./Mexican border is an example of a scarce, transboundary water resource over which conflict has already begun. The data collection and modeling effort described in this report aims at developing methods for international collaboration, data collection, data integration and modeling for simulating geographically large and diverse international watersheds, with a special focus on the Rio Grande/Rio Bravo. This report describes the basin, and the data collected. This data collection effort was spatially aggregated across five reaches consisting of Fort Quitman to Presidio, the Rio Conchos, Presidio to Amistad Dam, Amistad Dam to Falcon Dam, and Falcon Dam to the Gulf of Mexico. This report represents a nine-month effort made in FY04, during which time the model was not completed.

  14. Mapping of environmental radioactivity in sandy beaches of Ilha Grande, Rio de Janeiro, Brazil

    International Nuclear Information System (INIS)

    In determining reference levels of environmental radioactivity in ten beaches of Ilha Grande-R J, one used the measurement of gamma dose rates in situ (n Gy h-1) and the conversion of activity concentration of natural radionuclides 238Th, 232U and 40K (344/Kg) in samples from 0-10 cm sand profile, into gamma dose rate. Besides, the activity concentrations of studied radionuclides in the 10-20 cm and 20-30 cm sand profiles were determined, in order to analyse their process of vertical migration. Among the studied beaches, Preta Beach and Dois Rios Beach were selected to carry out a study of the gamma dose rates variation, during a period of twelve months. The annual absorbed dose rate at 1 m above ground level in the sand area was determined through the measurements of gamma dose rate carried out in situ on the beaches. The mean values of gamma dose rate in situ (n Gy h-1) in the analysed beaches ranged of 62 +- 7 in Dois Rios Beach to 126 +- 24 in Preta Beach. The primordial radionuclide 40K was the first contributor for the local gamma dose rate in eight studied beaches. None of studied beaches were considered a radiological risk. Sand features, such as porosity and density contribute to modulate the local environmental radiation levels. The comparison of gamma dose rate values from ten studied beaches, obtained through the two different techniques, showed high similarity between the results (R = 0.85). During the period of study in both analysed beaches, Preta and Dois Rios beaches, there was no variation statistically significant in the terrestrial gamma dose rate measured in situ. The higher annual absorbed dose rates were found in Preta Beach and in Caxadaco Beach, with 0.15 +- 0.03 mSv y-1 and 0.10 +- 0.02 mSv-1 respectively; while in the others beaches the mean value of gamma dose rate was 0.08 mSv y-1. The values of annual absorbed dose rate shown in this work are below that the values found in some beach areas of the world. (author)

    Full Text Available Ion input via rainfall alone and after interception by the forest canopy, constitutes an important path ofbiochemical cycling, although few studies have provided information on the subject so far. The objective of this work is toquantify ion inputs, via rainfall, in the southwestern region of Rio Grande do Sul state, Brazil. Ten rain gauges were mountedin a field area. The quantification of stored water volume, along with sample collection for determination of nitrate, nitrite,ammonium, phosphorus, sulfur, chlorine, calcium, magnesium, potassium and sodium contents, was done fortnightly fromSeptember 2006 to August 2008. Local annual average precipitation in the relevant period was 1,588.3 mm. The concentrationof chemical elements in rainwater was found to vary throughout, being inversely correlated with the increase in rainfall, whilepotassium, ammonium, phosphate, sulfate, chloride and sodium were found to have a significant mutual correlation (p <0.01.Based on the annual amount of nutrient input via rainwater, it can be inferred that rainfall is an important source of chemicalelement input into the forest system.

  17. Heat and extension at mid- and lower crustal levels of the Rio Grande rift

    The process by which large amounts (50 to 200 percent) of crustal extension are produced was concisely described by W. Hamilton in 1982 and 1983. More recently, England, Sawyer, P. Morgan and others have moved toward quantifying models of lithospheric thinning by incorporating laboratory and theoretical data on rock rheology as a function of composition, temperature, and strain rate. Hamilton's description identifies three main crustal layers, each with a distinctive mechanical behavior; brittle fracturing and rotation in the upper crust, discontinuous ductile flow in the middle crust and laminar ductile flow in the lower crust. The temperature and composition dependent brittle-ductile transition essentially defines the diffuse boundary between upper and middle crust. It was concluded that the heat responsible for the highly ductile nature of the lower crust and the lensoidal and magma body structures at mid-crustal depths in the rift was infused into the crust by relatively modest ( 10 percent by mass) magmatic upwelling (feeder dikes) from Moho levels. Seismic velocity-versus-depth data, supported by gravity modeling and the fact that volumes of rift related volcanics are relatively modest ( 6000 cubic km) for the Rio Grande system, all imply velocities and densities too small to be consistent with a massive, composite, mafic intrusion in the lower crust.

    Synoptic sampling has been performed along the Rio Grande from the headwaters in Colorado to Fort Quitman, Texas, south of El Paso. Samples from August 2001 and January 2002 were analyzed for nitrate (NO3-), ammonium (NH_{4}$+), total dissolved nitrogen (TDN), and dissolved organic carbon (DOC). DOC concentrations increase slowly between Colorado and southern New Mexico and then approximately double in Texas. Large sources of N during both sampling periods were the urban areas around Albuquerque and El Paso, Texas and Ciudad Juarez, Mexico, and agricultural regions in the Rincon and Mesilla valleys of southern New Mexico. Nitrate-N concentrations remained high south of Albuquerque to Elephant Butte reservoir in the summer, presumably due to lack of primary production. Inorganic N concentrations generally are higher in the winter than in the summer. During the summer, ammonium concentrations were greater than 100 mg N/l only at the outlet of Elephant Butte Reservoir, and in Texas. However, winter concentrations were on average an order of magnitude greater, again with the largest ammonium values (5000 \\mug N/l) in Texas. These patterns are consistent with a reduction in biological nutrient demand during the non-growing season.

No managed honey bee (Apis mellifera L. hives were in any of the fields; however, two contained managed hives of the common eastern bumble bee, Bombus impatiens (Cresson. A total of 15 species were collected or observed from all three fields combined. Of these species, only four were found to be very abundant: Agapostemon angelicus Cockerell/texanus Cresson, A. mellifera, Lasioglossum coactum (Cresson, and Melissodes thelypodii Cockerell. Apis mellifera comprised 46% of all bees collected from all three fields combined and was highly abundant in two of the three fields. In the third field, however, A. mellifera and Agapostemon angelicus/texanus were equally abundant. Surprisingly, B. impatiens comprised only 1% of the total bees surveyed in all three fields combined, despite two of the fields having several managed hives each. As B. impatiens is not native to this region, it was not surprising that none were collected or observed in the field with no managed hives.

  2. Assessment of metal concentrations in sediment samples from Billings reservoir, Rio Grande tributary, Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    The present study chemically characterized sediment samples from the Billings reservoir, Rio Grande tributary, in the Metropolitan region of Sao Paulo, by determining metal concentration and other elements of interest. The chosen chemical parameters for this characterization were Aluminum, Arsenic, Barium, Cadmium, Copper, Chromium, Iron, Lead, Manganese, Mercury, Nickel, Selenium and Zinc. These parameters are also used in the water quality index, with the exception of Selenium. The concentrations were determined through different analytical techniques such as atomic absorption spectrometry (FAAS, GFAAS and CVAAS), optical emission spectrometry (ICP OES) and neutron activation analysis. These analytical methodologies were assessed for precision, accuracy and detection and/or quantification limits for the sediment elements in question. Advantages and disadvantages of each technique for each element and its concentration were also discussed. From these assessment the most adequate technique was selected for the routine analysis of sediment samples for each element concentration determination. This assessment verified also that digestion in a closed microwave system with nitric acid is efficient for the evaluation of extracted metals of environmental interest. The analytical techniques chosen were equally efficient for metals determination. In the case of Cd and Pb, the FAAS technique was selected due to better results than ICP OES, as it does not present matrix interference. The concentration values obtained for metals As, Cd, Cu, Cr, Hg, Ni, Pb and Zn in the sediment samples were compared to Canadian Council of Minister of the Environment (CCME) TEL and PEL values.

    1988-01-01

    The serologic response of Rio Grande wild turkeys (Meleagris gallopavo intermedia) to Mycoplasma gallisepticum (MG) was determined. Free-ranging turkeys were caught in southern Texas, shipped to the University of Wisconsin, Madison, and housed in isolation facilities. Fourteen birds were exposed to MG, by intratracheal and intranasal inoculation. Eight birds received sterile broth only. Two wk prior to the end of the experiment, MG exposed turkeys were stressed by challenge with a serologically unrelated mycoplasma. Serum from all exposed birds reacted positively for MG antibody by the rapid plate agglutination (RPA) procedure within 2 mo postexposure (PE) and all but one remained positive for 14 mo PE. Less than one half of the exposed birds developed positive MG antibody titers detectable by the hemagglutination inhibition (HI) test within 2 mo PE, and by 10 mo PE, none had positive titers. Antibody was detected by the HI test in two of 11 infected turkeys, 14 mo PE, and titers increased significantly within 2 wk. MG was isolated from tracheal swabs from two infected birds 2 mo PE, but attempts thereafter failed. However, at the termination of the experiment 15 mo later, MG was isolated from lung tissue of three of 11 exposed turkeys and from a blood clot found in the lower trachea of one bird.

    Full Text Available Wind power generation has a reputation for being environmentally friendly. However, beyond its clean and renewable aspects, the exploration fields can also be assessed in its relationship with the geographical space, as the risks involved in this activity can be identified in all project phases, going from its implementation to the final moment where the actual energy generation takes place. This article provides a description of the risks related to the physical environment of the wind power generation fields of Macambira I and II, Baixa do Feijão and Aventura, all located in the state of Rio Grande do Norte, Brazil. Although the research focuses on the physical context of the generation fields, it also indicates that social relationships are affected by it. Particularly, the geology mapping demonstrates that there are risks related to the presence of caves. This morphology can be seen on the Jandaíra Formation limestone, which is marked by a subterranean tunnel network that occurs in plain terrains. Beyond the geotechnical aspect, which exposes the wind power towers to some risk, there are environmental concerns regarding the regional hidrogeology and the speleological patrimony, as well as the fossil layers that are present on the sedimentary formations. Furthermore, the regional seismic context can also offer risks to the installation of wind power generation towers.

    In response to a request from employees at the Buckeye Hills Career Center (SIC-8249) located in Rio Grande, Ohio, an investigation was made of symptoms experience by the Cosmetology instructors which were believed to be associated with exposures to hair care and cosmetology products used in the Cosmetology Clinic. Employees were interviewed, and environmental sampling was conducted. The use of paraformaldehyde (30525894) cabinet fumigants was found to be a source of airborne formaldehyde (50000) and contributed to airborne formaldehyde concentrations within the clinic. Sample results showed high airborne concentrations of formaldehyde within towel cabinets and student cosmetic kits. Inadequate amounts of fresh outside air were supplied to the Clinic. Other products containing formaldehyde also contributed to the air quality. The authors conclude that a potential hazard existed due to exposure to formaldehyde. The authors recommend that where substances without formaldehyde could be substituted for those containing formaldehyde that the substitution be made. If product elimination or substitution is not feasible, then exposures should be controlled through the use of local exhaust ventilation.

    Full Text Available Ethnobotanical data can be an important tool in the search for new drugs. The Brazilian Health Surveillance Agency accepts the registration of herbal medicines based on ethnopharmacological and ethnobotanical studies. With the purpose of increasing the knowledge of potentially useful plants for the treatment of painful conditions, we analyzed the ethnobotanical studies carried out in Rio Grande do Sul state (RS-Southern Brazil; we had access to nineteen studies.To our knowledge, this is the first compilation of ethnobotanical studies that focus on pain relief carried out in RS. The species native to RS cited in at least nine (about 50% of these studies were selected. The search retrieved 28 native species cited as used to alleviate painful conditions, which are distributed in eighteen botanical families, being Asteraceae the most mentioned. The species more frequently cited for pain relief were Achyrocline satureioides, Baccharis articulata, Baccharis crispa, Lepidium didymum, Eugenia uniflora and Maytenus ilicifolia. The only species not reported in any pre-clinical study associated with pain relief was B. articulata. Among the six species cited, no studies on clinical efficacy were found. In conclusion, the folk use of native plants with therapeutic purposes is widespread in RS State (Brazil, being pain relief an important property.

    β(S) haplotypes were studied in 47 non-related patients with sickle-cell anemia from the state of Rio Grande do Norte, Brazil. Molecular analysis was conducted by PCR/RFLP using restriction endonucleases XmnI, HindIII, HincII and HinfI to analyze six polymorphic sites from the beta cluster. Twenty-seven patients (57.5%) were identified with genotype CAR/CAR, 9 (19.1%) CAR/BEN, 6 (12.8%) CAR/CAM, 1 (2.1%) BEN/BEN, 2 (4.3%) CAR/Atp, 1 (2.1%) BEN/Atp and 1 (2.1%) with genotype Atp/Atp. The greater frequency of Cameroon haplotypes compared to other Brazilian states suggests the existence of a peculiarity of African origin in the state of Rio Grande do Norte. PMID:21931513

    2004-01-01

    The high prevalence of beta thalassemia among Italians and their participation in the ethnic formation of Caxias do Sul, Rio Grande do Sul State, Brazil, and neighboring cities prompted us to investigate hemoglobinopathies in 608 blood donors at the Caxias do Sul Regional Blood Center. Despite the ethnic influence, abnormal hemoglobin levels were found in only 1.81% of the donors (0.16% Hb AC, 0.99% Hb AS, and 0.66% Hb AH), similar to the levels observed in a study on qualitative disorders conducted in the rural area of Rio Grande do Sul. In our setting, the most commonly used screening tests for thalassemia, combined with DNA sequencing, were unable to detect quantitative hemoglobin synthesis disorders. This may be attributable to still-unknown genetic disorders, technical limitations, or simply to miscegenation. PMID:15608861

    Although the period following 1930 has been considered an era in which homeopathy lost ground within academia, homeopaths nevertheless were advocating for their proposals in a variety of spaces. One such instance was represented by the Homeopathic League of Rio Grande do Sul, founded in 1941, which published a journal until the 1970s, set up three free dispensaries to serve the population in Porto Alegre, and played an active role in political discussions through a group of homeopaths who endeavored to disseminate and expand homeopathic practice. An analysis of the League's Boletim de Homeopatia provides insight into homeopaths' strategies for expanding their role in Porto Alegre, capital of Rio Grande do Sul. PMID:21779687

    Science.gov (United States)

    Sigda, John M.; Goodwin, Laurel B.; Mozley, Peter S.; Wilson, John L.

    Faults in clastic rocks influence fluid flow by juxtaposition of different lithologic units and by localized alteration of petrophysical properties through cataclasis, cementation, or other deformational and diagenetic processes. Extensional tectonic settings, such as the Basin and Range Province and the Rio Grande rift, are characterized by numerous faults in both sedimentary rocks and poorly lithified basin-fill sediments. Faults in poorly lithified sediments have received little attention; our study is the first to examine their permeability. We tested whether faulting of poorly lithified sediments significantly affects permeability by comparing two uncemented, small-displacement, normal faults in New Mexico's central Rio Grande rift: one with a clay-rich core (displacement > bed thickness) and one without a clay-rich core (displacement Southwest. Numerous in extensional basins but typically not included on most geologic maps, such faults could significantly influence flow through basin-fill sediments.

Todos os rebanhos foram submetidos a procedimentos de vacinação e/ou aplicação de anti-helmíntico entre 8 e 25 dias antes do aparecimento dos primeiros sinais clínicos. O tempo de evolução variou de 12 horas até quatro dias. Os sinais clínicos observados foram: prolapso da terceira pálpebra, andar rígido, dificuldade de flexão dos membros e permanência em decúbito lateral com os membros estendidos e afastados do solo (paralisia espástica, pálpebras muito abertas, sialorréia, hiperexcitabilidade, orelhas eretas, trismo mandibular, acúmulo de alimento na cavidade oral e presença de espuma na boca e narinas em alguns casos. Alguns bovinos apresentavam área de necrose e edema hemorrágico circundada por exsudato purulento nos músculos onde havia sido aplicado algum medicamento. O soro sanguíneo e fragmentos de músculo com lesão de animais afetados foram coletados para posterior inoculação em camundongos. No exame histopatológico não foram evidenciadas alterações. O quadro clínico associado aos dados epidemiológicos e a ausência de lesões histológicas permitiram o diagnóstico de tétano. A infecção, provavelmente ocorreu durante o procedimento de vacinação, através injeções intramusculares utilizando agulhas contaminadas. Apesar do tétano não ser uma clostridiose importante na região fica evidenciado que surtos podem ocorrer em função de condições epidemiológicas adequadas e cuidados devem ser tomados para evitar perdas econômicas importantes como as que ocorreram no ano 2009 na região.

    An experiment site was constructed along an artificial channel of the Rio Grande in El Paso, Texas. The experiment was funded by the EPA and is designed to measure the effectiveness of bank filtration in an arid environment. Regionally, the experiment is important because of the hundreds of thousands of people drinking water from shallow wells drilled in close proximity to septic systems. A pumping well was drilled 17 meters from the stream bank and screened from 3.5 to 8 m depth. A cruciform array of observation wells with several multilevel completions allows detection of downstream and vertical movement of water as well as flow from the stream to the well. All of the wells were continuously cored during drilling. Analysis of the cores reveals that the site consists of two stacked channels filled with sand deposited from the meandering Rio Grande. A grid of ground-penetrating radar lines provided three-dimensional coverage between wells and showed bedding to 6.5 m depth. Constant head hydraulic conductivities show that the aquifer consists of two more permeable units separated by the less permeable upper fill of the lower channel complex, with vertical hydraulic conductivities of (1x10-6 to 2x10-6 m/s?). The intervals above and below this interval have the highest vertical conductivities (up to 3.5x10-5 m/s). A multiple pumping and tracer test was conducted using the cruciform array of the field site that consisted of a pumping well, 16 observation wells, and a stream sampling point. The average hydraulic conductivity of the geological media at the field site was about 2 x 10-3 m/s based on pumping test analysis. However, the type curve responses revealed significant heterogeneity of hydraulic conductivity throughout the field site. For the tracer test, bromide and microspheres were used as tracers. Microspheres were used to mimic the behavior of Giardia and Cryptosporidium. The tracers (bromide and microspheres of different sizes and colors) were injected in one

    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.

    Full Text Available Salmonella has been identified as the main aetiological agent responsible for foodborne diseases in several countries worldwide, including Brazil. In the State of Rio Grande do Sul (RS, southern Brazil, previews studies analysed official foodborne illnesses data, identifying Salmonella as the main bacterial agent of foodborne diseases during the period of 1997 to 2001. The present study aimed to analyse the official epidemiological data on salmonelloses occurred in the State of RS, during the period of 2002 to 2004. Even though data on recent salmonelloses were available, only data concerning the period comprising in 2002 to 2004 were analysed because the official worksheet records presented more consistent information about the salmonellosis outbreaks. Results indicated that, among the 624 foodborne outbreaks officially investigated, 202 (32.37% were confirmed as salmonellosis. Among them 23,725 people were involved, 4,148 became sick, 1,878 were hospitalized and one person died. The season with the highest incidence of salmonelloses was spring, and the most affected age group was composed of people aged between 20 to 49 years old (56.66%. Animal origin foods -especially eggs and meat products -were very often involved with the outbreaks, however homemade mayonnaise was identified as the main food vehicle for salmonelloses (53.51%. The majority of the cases occurred inside private homes (55.81% and food services (12.1%, and the main factors contributing to the occurrence of the outbreaks were the consumption of products without sanitary inspection (26.7% and exposure of food at room temperature for more than two hours (18.58%. Similarly to what was previously reported for the period of 1997 to 2001, Salmonella spp. was the most prevalent foodborne disease agent in the State of RS during the years of 2002 to 2004.

    Full Text Available This study estimated the water footprint of pigs slaughtered in the municipalities that participate in the Regional Council for the Development of Serra (Corede Serra, in Portuguese, located in the northeast region of Rio Grande do Sul State, in 2014. In order to determine the water footprint, we estimated the water consumed in the production of grains (corn and soybeans used for animal feed, the water used for livestock watering, the water used for cleaning creation areas and the water consumed by animals during the growing and finishing phases. The total water footprint of slaughtered pigs was 0.19825 km3, the largest component of which was water used for the cultivation of grains (99.6%. The municipality of Nova Prata had the largest water footprint of Corede Serra (0.02343 km3 year1, followed by the municipalities of Paraí (0.02187 km3 year-1 and Serafina Corrêa (0.01658 km3 year-1. The municipalities of São Marcos (0.000006 km3 year-1, Bento Gonçalves (0,00002 km3 year-1 and Boa Vista do Sul (0.0004 km3 year-1 had the lowest water footprints, due to low corn productivity associated with the low number of hogs slaughtered. From this assessment, it was found that the management of water resources associated with pig chain production should include water used in the production of feed grain as well as the water used directly in animal husbandry.

    Full Text Available No Brasil, a avaliação da efetividade de programas de prevenção e ações de saúde pública ainda são incipientes. Dessa forma, realizou-se um estudo transversal de base populacional envolvendo a saúde da população adulta residente na zona urbana da cidade de Pelotas, Rio Grande do Sul, Brasil, com o objetivo de verificar a evolução nos níveis de cobertura do exame citopatológico. Investigaram-se fatores associados com a não realização do procedimento. Considerou-se exame citopatológico atualizado aquele realizado nos últimos três anos. A amostra foi constituída por 1.122 mulheres entre 20 e 69 anos, sendo que 72,2% apresentavam exame citopatológico atualizado, 16,6% atrasado e 11,2% nunca o haviam realizado. A não realização do procedimento esteve associada com baixa inserção social e idade avançada. A regressão logística destacou o efeito independente de classe social, baixa renda familiar, idade, cor da pele, estado civil e ausência de consultas médicas no último ano. Contudo, desapareceu o efeito detectado em mulheres com doenças crônicas. Comparando-se os resultados do estudo realizado em 1992 com o atual, observa-se que a cobertura do exame aumentou de 65,0% para 72,2% (1992 para 1999/2000, entretanto, não atingiu os níveis efetivos para evitar câncer de colo uterino.

    Full Text Available Leptospirosis is an epidemic-prone neglected disease that affects humans and animals, mostly in vulnerable populations. The One Health approach is a recommended strategy to identify drivers of the disease and plan for its prevention and control. In that context, the aim of this study was to analyze the distribution of human cases of leptospirosis in the State of Rio Grande do Sul, Brazil, and to explore possible drivers. Additionally, it sought to provide further evidence to support interventions and to identify hypotheses for new research at the human-animal-ecosystem interface.The risk for human infection was described in relation to environmental, socioeconomic, and livestock variables. This ecological study used aggregated data by municipality (all 496. Data were extracted from secondary, publicly available sources. Thematic maps were constructed and univariate analysis performed for all variables. Negative binomial regression was used for multivariable statistical analysis of leptospirosis cases. An annual average of 428 human cases of leptospirosis was reported in the state from 2008 to 2012. The cumulative incidence in rural populations was eight times higher than in urban populations. Variables significantly associated with leptospirosis cases in the final model were: Parana/Paraiba ecoregion (RR: 2.25; CI95%: 2.03-2.49; Neossolo Litolítico soil (RR: 1.93; CI95%: 1.26-2.96; and, to a lesser extent, the production of tobacco (RR: 1.10; CI95%: 1.09-1.11 and rice (RR: 1.003; CI95%: 1.002-1.04.Urban cases were concentrated in the capital and rural cases in a specific ecoregion. The major drivers identified in this study were related to environmental and production processes that are permanent features of the state. This study contributes to the basic knowledge on leptospirosis distribution and drivers in the state and encourages a comprehensive approach to address the disease in the animal-human-ecosystem interface.

    Full Text Available http://dx.doi.org/10.5902/198050989293The objective was to evaluate the energy potential of woods of species under forest management plan from Seridó region in the Rio Grande do Norte state. It was used the wood species Jurema Preta, Pereiro, Marmeleiro, Catingueira, Mororó, Imburana, Jurema Branca and Mofumbo, at 20 years old, originated from the Dominga´s farm in the Caicó/RN municipality. The density, the content of volatiles, the ash and fixed carbon, calorific value, elemental composition and carbon/nitrogen (C/N and carbon/hydrogen (C/H analysis were carried out in the wood. Additionally, the amount of energy produced in kW.h.m-3 and kW.h.ha-1 for all species was estimated. The experiment was conducted in a completely randomized design with eight treatments (species, four replicates (sample trees, adding up to 32 sampling units. There were significant differences, at 5% significance between treatments for all variables, except for hydrogen percentage and C/H ratio. It was concluded that Mororó´s wood shows high energy potential, and along with Jurema Preta, presents higher energy generation per m3, and provides greater economy for the same productivity. The energy potential Jurema Preta wood´s stands out among the species. Pereiro´s wood stands for energy production per hectare. Marmeleiro and Jurema Branca´s woods are indicated as direct burning potential and Imburana´s wood is not recommended for power generation.

    Full Text Available Introduction: Alcoholism has been a major concern of public health worldwide. According to the World Health Organization (WHO, approximately 76.3 million people presented problems of alcohol abuse in 2004. Therefore, the risks arising from the association of psychiatric disorders with alcohol consumption should also be considered in the context of mental health services. Objective: This study aimed to analyze alcohol consumption by the users of Therapeutic Residential Services- SRT and Psychosocial Care Centers- CAPS in five municipalities in the state of Rio Grande do Sul, Brazil. Methodology: The present study is part of a research entitled Rehabilitation Networks - REDESUL, carried out from September to December 2009 in five municipalities of the aforementioned Brazilian state. The total sample comprised 392 users: 143 from the SRT and 270 from the CAPS services, with intersection of 21 members. Results: The results showed that of the 392 care service users, only 29 had consumed alcohol during the four weeks prior to the survey. The majority of these 29 users were between 31 and 59 years old, male, single, and only n = 13 (48.28% reported being aware of their psychiatric disorders, with prevalence of schizophrenia n = 7 (24.13% followed by bipolar disorders n = 3 (10.34%. Conclusion: It is necessary that the mental health teams are also trained to work with alcohol users, regardless of the type of mental health service they work for, and that they develop actions in relation to guidance on alcohol consumption, treatment adherence, rehabilitation, and integration of users to the community.

    The SAGE (Summer of Applied Geophysical Experience) program collected new gravity, seismic, electromagnetic and down-hole temperature data in 2014 in the Santo Domingo Basin and adjacent areas of the Rio Grande Rift (RGR) area of northern New Mexico. The SAGE 2014 data collection was part of an integrated geophysical study of the area initiated in 2010 and adds data and interpretations to a W to E transect of the RGR. The transect includes previous SAGE seismic refraction and CMP reflection profiles recorded in 2010 and 2011, some industry seismic reflection data, and detailed gravity observations. Seismic data consisted of a 4.8 km NW to SE profile (120 three-component stations in four overlapping deployments, 20 m station spacing, using a Vibroseis source - 20 m spacing for reflection VPs; 800 m spacing for refraction VPs) along the Borrego Canyon road with both refraction and CMP reflection coverage. About 50,000 seismograms were recorded. The surface conditions (dry unconsolidated sediments) increased surface wave energy and limited the signal-to-noise level of reflection arrivals although some wide-angle reflections with two-way times as great as 1.8 s were visible. The refraction data were modeled with first arrival travel time methods and mainly helped identify the velocity and minimum thickness of the Tertiary Santa Fe group sedimentary rocks in the Santo Domingo Basin. Interpretation of the seismic and gravity data along the transect was aided by refraction velocities, the existence of a nearby regional seismic reflection profile from industry, and lithologies and well-logs from a deep well. Gravity modeling, with significant control on depths of interfaces and densities from the seismic and drill hole data, indicates that the Santo Domingo sedimentary basin has a total depth of about 6 km.

    Participants in the Summer of Applied Geophysical Experience (SAGE) program have collected gravity data at over 7000 locations in the northern Rio Grande rift (RGR) area of New Mexico in the past thirty-three years. In recent years, the SAGE program has focused on the western edge of the Española basin and the transition into the Santo Domingo basin of the RGR. During this time, we have collected about 40 km of seismic reflection and refraction data along approximately East-West profiles using a 120 channel data acquisition system with a 20 m station interval and a Vibroseis source. Refraction travel time modeling and Common Midpoint (CMP) stacked reflection sections have imaged basin boundary faults and stratigraphy. We also have access to several energy-industry seismic reflection record sections from the 1970s in the study area. These data and some deep drill hole information have allowed detailed interpretation of basin structures along segments of three regional transects across the RGR in northern New Mexico. The interpreted seismic velocities and fault images from the seismic record sections, and lithologies and well logs from drill holes, have also provided important constraints on modeling and interpretation of the regional gravity data along the three transects. The gravity modeling along these transects reveals key structures within the basin including the eastern bounding fault of the Los Alamos graben, eastern boundary faults of the Santo Domingo basin, the Agua Fria fault system near the eastern boundary of the Española basin and interpreted depths to basement of the Española and Santo Domingo basins. Boundary fault offsets are as large as 3 km and maximum basin depths range from 3 to 6 km.

  2. Mutation breeding of wheat and triticale in Rio Grande do Sul State, Brazil

    International Nuclear Information System (INIS)

    A mutation breeding programme was initiated in 1985 at IPAGRO in Rio Grande do Sul State, Brazil. Seeds from several wheat (Triticum aestivum) and triticale hexaploid cultivars were treated with 60Co gamma rays and ethylmethanesulphonate (EMS) to induce mutants resistant to diseases, shorter in height, and earlier maturing. In addition, F1 seeds from crosses between triticale and wheat were irradiated with gamma rays to increase translocations and recombinations. In the M1 generation, the F1 plants were backcrossed to triticale. In 1989, the first local replicated yield trials consisted of 1072 genotypes selected from the different populations. From these yield trials, 11 cooperative trials consisting of 245 genotypes were organized in 1990 and distributed in 3 different regions in the state. From 3 wheat trials, 14 mutant lines were selected on the basis of superior yields. Among these, some lines from RS-2 are of special interest because of reduced leaf rust. Some lines from Butui were shorter and earlier than the original parent. Mutant lines derived from the irradiated hybrids of triticale x wheat were tested in 8 yield trials. From 4 of the trials, 28 lines were selected because of higher yields than that of the triticale control, TAS-1. In the other 4 trials the lines lacked uniformity, therefore, new selections were made. In comparing the selected genotypes of triticale with the control, several lines were superior in weight of hectoliter but no useful lines were identified for semidwarfness, earliness, or higher 1000-grain weight. Evidence for the success of the mutation breeding programme is not only the promising advance mutant lines but also thousands of selected plants which are still being evaluated.

    Full Text Available Neste trabalho, objetivou-se analisar o comportamento de tendência, sazonalidade e ciclos dos preços reais pagos ao produtor de leite do Rio Grande do Sul de 1973 a 2007, bem como a evolução dos preços ao consumidor e da margem de comercialização. O estudo foi realizado com base nas séries históricas de preços nominais mensais de leite pagos ao produtor e pelos consumidores no Rio Grande do Sul, obtidas junto à EMATER/RS e ao IEPE/UFRGS, respectivamente. Os preços nominais foram deflacionados para dezembro de 2007 pelo IGP-DI da FGV. Calcularam-se os Índices de Preço ao Consumidor e ao Produtor, Índices de Estacionalidade, Relativos de Ciclo e Margens de Comercialização do produto. Observou-se que os preços pagos ao produtor apresentaram tendência de queda durante toda a série histórica. O mercado de leite apresentou ciclos históricos pouco regulares até o início da década de 1980, e a partir de 1987 observou-se forte tendência de mudança na trajetória dos índices de preço ao produtor e ao consumidor. A margem de comercialização do leite cresceu no período analisado, situando-se entre 27% e 69%.The objective of this study is to analyse tendency behaviour, seasonality and price cycles of real prices paid to milk farmers in Rio Grande do Sul between 1973 and 2007, as well as the evolution of consumer prices and commercialization margins.

    High salinity in the Rio Grande has led to severe reductions in crop productivity and accumulation of salts in soils. These pressing issues exist for other arid rivers worldwide. Salinity contributions to the Rio Grande have not been adequately quantified, especially from agriculture, urban activities, and geological sources. Here, we use major element concentrations and U, S, B, Sr isotopic signatures to fingerprint the salinity sources. Our study area focuses on a 200 km long stretch of the Rio Grande from Elephant Butte Reservoir, NM to El Paso, TX. River samples were collected monthly from 2014 to 2015. Irrigation drains, groundwater wells, city drains and wastewater effluents were sampled as possible anthropogenic salinity end-members. Major element chemistry, U, S and Sr isotope ratios in the Rio Grande waters suggest multiple salinity inputs from geological, agricultural, and urban sources. Natural upwelling of groundwater is significant for the Rio Grande near Elephant Butte, as suggested by high TDS values and high (234U/238U), 87Sr/86Sr, δ34S ratios. Agricultural activities (e.g. flood irrigation, groundwater pumping, fertilizer use) are extensive in the Mesilla Valley. Rio Grande waters from this region have characteristic lower (234U/238U), 87Sr/86Sr, and δ34S ratios, with possible agricultural sources from use of fertilizers and gypsum. Agricultural practices during flood irrigation also intensify evaporation of Rio Grande surface water and considerably increase water salinity. Shallow groundwater signatures were also identified at several river locations, possibly due to the artificial pumping of local groundwater for irrigation. Impacts of urban activities to river chemistry (high NO3 and B concentrations) were evident for locations downstream to Las Cruces and El Paso wastewater treatment plants, supporting the use of the B isotope as an urban salinity tracer. This study improves our understanding of human impacts on water quality and elemental

    Full Text Available Reports of cyanobacterial blooms developing worldwide have considerably increased, and, in most cases, the predominant toxins are microcystins. The present study reports a cyanobacterial bloom in Lake Violão, Torres, Rio Grande do Sul State, in January 2005. Samples collected on January 13, 2005, were submitted to taxonomical, toxicological, and chemical studies. The taxonomical analysis showed many different species of cyanobacteria, and that Microcystis protocystis and Sphaerocavum cf. brasiliense were dominant. Besides these, Microcystis panniformis, Anabaena oumiana,Cylindrospermopsis raciborskii, and Anabaenopsis elenkinii f. circularis were also present. The toxicity of the bloom was confirmed through intraperitoneal tests in mice, and chemical analyses of bloom extracts showed that the major substance was anabaenopeptin F, followed by anabaenopeptin B, microcystin-LR, and microcystin-RR.O número de relatos de ocorrências de florações de cianobactérias em todo o mundo vem aumentando consideravelmente e na maioria desses episódios, as toxinas dominantes são as microcistinas.

  4. The Evolution of Riparian Landscape Elements Following Upstream Regulation and Depletion on the Rio Grande

    In 1915 closure of Elephant Butte Dam in central New Mexico profoundly altered the hydrologic regime of the Rio Grande for 560 km downstream, and set in motion a cascade of interwoven geomorphic, biological, and cultural responses. Geomorphic response included shrinking of the width and depth of the channel, and an increase in sinuosity. Cultural responses included artificial channel modification on 320 km of the river within the boundaries of the original irrigation project, beginning in 1933. The pre-dam river and its flood plain consisted of a mosaic of geomorphic elements that formed a functional riverine landscape, and founded a diverse habitat for the plants, animals, and people that lived there. A preliminary comparison of the modern river with pre-dam topographic mapping permits identification of individual landscape elements, including overflow land (flood plain) both cultivated and uncultivated, with oxbows and back-swamps. The pre-dam channel included a low water thread and un-vegetated flood bars. From pre-dam description and photographs we can assume the usual complement of pools and riffles, point bars and undercut banks. Until dredged in the 1970s, the unmodified reach retained the entire suite of landscape elements, although in somewhat different proportions from the pre-dam river, and remained a functional riparian system. Channel sinuosity increased from 1.45 in 1910 to 1.7 in 1970, thus riverbank habitat increased by 1.17%. In 1970 undercut banks still provided protection for fish, and point bars generated by lateral migration still provided seed beds for pioneer species. The smaller shallower channel raised groundwater beneath the flood plain and retarded flood waves, creating a generally more mesic environment, although the river occasionally dries up, as it did prior to 1915. In contrast, an impoverished suite of landscape elements characterizes the channelized reach. Lateral stability precludes point bars and undercut banks. Bounding levees

    The SAGE (Summer of Applied Geophysical Experience) program collected new seismic, gravity, electromagnetic and down-hole temperature data in 2013 in the western Espanola basin of the Rio Grande rift area of northern New Mexico. The location, about 25 km NW of Santa Fe, has been identified as a potential geothermal resources area based on relatively high temperature gradients in drill holes. The SAGE 2013 data collection was part of an integrated geophysical study of the area initiated in 2011. Seismic data consisted of a 4.8 km W to E profile (120 three-component stations in four overlapping deployments, 20 m station spacing, using a Vibroseis source - 20 m spacing for reflection VPs; 800 m spacing for refraction VPs) with both refraction and CMP reflection coverage. About 55,000 seismograms were recorded. The surface conditions (dry unconsolidated sediments) increased surface wave energy and limited the signal-to-noise level of the refraction and reflection arrivals. Utilizing longer source-receiver offsets improved the shot-gather record sections by emphasizing wider angle reflections which are very strong and coherent. The refraction data were modeled with first arrival travel time methods. The reflection data were processed to produce a CMP stacked record section. Strong reflectors from basin-filling sedimentary rocks (mostly Tertiary in age) are visible above reflections from a thin section of Paleozoic rocks and the basement. The lower reflections have an apparent dip to the west of about 12 degrees. Eighty-one new gravity measurements (detailed data at 200 m spacing along the seismic profile, and regional stations) were collected and combined with existing regional data for modeling. Interpretation of the seismic and gravity data was aided by refraction velocities, the existence of a nearby regional seismic reflection profile from industry, and lithologies and well-logs from a deep well. The sedimentary basin interpreted from the seismic and gravity data

    The Pajarito fault system is the local active boundary fault of the Rio Grande rift in the vicinity of Los Alamos, New Mexico. Detailed geologic and geomorphic mapping, and displacement-length profiles, reveal a complex pattern of structural deformation that suggests interaction and connective growth among the principal faults in the system (Pajarito, Rendija Canyon, Guaje Mountain, and Santa Clara faults, totaling ~55 km in length). At the surface, the Pajarito fault is not a single shear surface but a complex zone of deformation with considerable lateral variation in structural style from south to north. In the area of detailed mapping, the Pajarito fault is a broad zone of distributed deformation: at the southwest corner of the area, structure is dominated by a large monocline, but small faults and monoclines span a breadth of about 2 km with about 125 m of displacement in the last 1.2 million years; at the west central part of the area, the Pajarito fault is expressed as mainly a large normal fault with smaller faults spread across about 1 km with about 80 m of displacement in the last 1.2 million years; and, in the northwestern part of the area, structure is again dominated by a large monocline with normal faulting in a zone about 1.5 km wide with about 65 m of displacement in the last 1.2 million years. These along-strike variations in the deformation of the Pajarito fault suggest that in most places the tip of the master fault does not break the surface; instead, most of what can be observed is subsidiary structure. The implication of the complex structure and styles of deformation in the fault is that it severely complicates paleoseismic exploration for hazard analyses because different subsidiary structures rupture in different seismic events; no individual structure can be identified with even a near- complete paleoseismic record. Additionally, surface rupture hazards must be associated with broad zones instead of individual faults. Seven paleoseismic

    The U.S. Bureau of Reclamation has identified the Rio Grande basin within Central New Mexico as one of several regions where water supplies are over-allocated and future conflicts over the inadequate resource are highly likely. Local water providers have consistently identified managed aquifer recharge (MAR) as an important tool to provide conjunctive management of surface-water, groundwater, and reclaimed water sources in order to extend the useful life of existing water sources. However, MAR projects have been slow to take root partly due to rigorous demonstration requirements, groundwater quality protection concerns, and ongoing water right uncertainties. At first glance the several thousand meters of unconsolidated basin-fill sediments hosting the regional aquifer appear to provide an ideal environment for the subsurface storage of surplus water. However, the basin has a complex structural and depositional history that impacts the siting and overall effectiveness of MAR systems. Several recharge projects are now in various stages of implementation and are overcoming site specific challenges including source water and ambient groundwater compatibility, low-permeability sediments and compartmentalization of the aquifer by extensive faulting, well clogging, and overall water quality management. This presentation will highlight ongoing efforts of these water providers to develop full-scale recharge facilities. The performance of natural in-channel infiltration, engineered infiltration galleries, and direct injection systems designed to introduce from 500 to 5,000 mega-liters per annum to target intervals present from 150 to 600 meters below ground surface will be described. Source waters for recharge operations include inter-basin transferred surface water and highly treated reclaimed water sources requiring from minor to extensive treatment pre-recharge and post-recovery. Operational complexities have raised concerns related to long-term operation and maintenance

    The Rio Grande/Bravo River Basin (RGB) of the United States and México is exposed to tornadoes, severe storms, hurricanes, winter storms, wildfire, and drought. The combination of these weather and climate-related hazards has resulted in impacts, such as wildfire, crop loss, water supply reduction, and flooding, with exceedingly high economic costs ($13 billion in 2011). In order to contribute to increased binational information flow and knowledge exchange in the region, we have developed a prototype quarterly bilingual RGB Climate Outlook, in PDF, supplemented by Twitter messages and Facebook posts. The goal of the project is to improve coordination between institutions in the U.S. and Mexico, increase awareness about climate variations, their impacts and costs to society, and build capacity for enhanced hazard preparedness. The RGB Outlook features a synthesis of climate products, impact data and analysis, is expressed in user-friendly language, and relies substantially on visual communication in contrast to text. The RGB Outlook is co-produced with colleagues in the U.S. and Mexico, in conjunction with the North American Climate Services Partnership (NACSP) and NOAA's regional climate services program. NACSP is a tri-national initiative to develop and deliver drought-based climate services in order to assist water resource managers, agricultural interests, and other constituents as they prepare for future drought events and build capacity to respond to other climate extremes. The RGB Climate Outlook builds on lessons learned from the Climate Assessment for the Southwest (CLIMAS) Southwest Climate Outlook (PDF, html), La Niña Drought Tracker (PDF, html), the Southern Climate Impacts Policy Program (SCIPP) Managing Drought in the Southern Plains webinar series, the Border Climate Summary (PDF), and Transborder Climate newsletter (PDF) and webinar series.

    Full Text Available OBJETIVO: Analisar os fatores associados ao uso de substâncias estimulantes por caminhoneiros para se manterem acordados. MÉTODOS: Survey com 854 motoristas em oito locais de concentração de caminhoneiros (sete postos de gasolina e um posto aduaneiro em região de fronteira em cinco municípios do Rio Grande do Sul, em 2006. O desfecho "uso de rebite" foi categorizado em "sim" ou "não". Foi realizada análise de regressão de Poisson com variância robusta para a seleção de variáveis do modelo, que foi composto por níveis socioeconômicos, demográficos, de informações sobre a profissão e sobre o consumo de álcool. RESULTADOS: O consumo de rebite para se manter acordado foi declarado por 12,4% dos caminhoneiros de forma isolada ou em combinação com outras substâncias (café, guaraná em pó, energéticos, cocaína aspirada. O rebite foi a substância mais citada por aqueles que consumiam algo para ficar acordados. A ingestão de bebidas alcoólicas foi prática de mais de 70% dos entrevistados, dos quais 45,1% relataram consumo pelo menos uma vez por semana. O uso de rebite esteve associado às faixas etárias mais jovens, ao aumento da renda, à maior duração das viagens e ao consumo de álcool. DISCUSSÃO: O aumento da remuneração dos caminhoneiros implica aumento da carga de trabalho. Isso produz desgaste físico e emocional, levando-os a buscar solução temporária no consumo de substâncias estimulantes. A redução do consumo abusivo de álcool e do uso ilícito de substâncias como anfetaminas por motoristas profissionais depende não só de políticas voltadas para a prevenção e tratamento de drogas, mas de políticas intersetoriais articuladas que garantam melhores condições de trabalho e de saúde aos caminhoneiros.

A Empresa Brasileira de Correios e Telégrafos (ECT, criada em 1969, configurada com muitas lojas similares em todo o Brasil, as quais prestam e comercializam um conjunto de produtos e serviços semelhantes, mas que utilizam recursos diversos em intensidade diferente, possui sua atual avaliação de desempenho das lojas centrada em um único fator econômico financeiro, denominado de Índice de Receitas e Despesas (R/D. Esse índice não considera fatores que estão sendo utilizados pelas lojas, fora da visão financeira. Dessa forma, neste artigo, propõe-se avaliar um conjunto de lojas da ECT do Rio Grande do Sul por meio de modelagem matemática, utilizando a técnica Data Envelopment Analysis (DEA - Análise Envoltória de Dados, que possibilita a inclusão de outras variáveis fora da visão econômica. Este trabalho tem por objetivo: 1. definir que variáveis podem ser utilizadas para a avaliação das lojas; 2. definir um conjunto de lojas similares, que executam as mesmas funções e que se diferenciam somente na intensidade da utilização dos recursos; 3. gerar, por meio da técnica, os resultados da avaliação, obtidos a partir dos fatores quantitativos definidos, realizando análises de sensibilidades; e 4. propiciar aos administradores um referencial para apoio à decisão. A utilização da técnica tornou possível: identificar fatores usados de forma distinta nas lojas; identificar práticas utilizadas pelas lojas 100% eficientes, que podem contribuir para as lojas não eficientes; e permitir e encorajar a participação dos gestores locais na alteração e extensão do modelo, levando em conta as características das lojas.

    Full Text Available No Brasil, foi desenvolvido um novo híbrido de mamão obtido através de melhoramento do cruzamento entre um progenitor do Grupo Formosa e um progenitor do Grupo Solo. Recentemente, os produtores de mamões do Rio Grande do Norte introduziram o cultivo desse híbrido em seus pomares: no entanto, os estudos acerca do potencial de conservação desses frutos restringem-se aos testes realizados nas próprias empresas. O presente trabalho propôs-se a avaliar a vida útil pós-colheita do mamão híbrido UENF/Caliman 01 cultivado no Estado do Rio Grande do Norte. Os frutos foram provenientes de um plantio comercial, localizado no município de Ceará-Mirim-RN. Os mamões foram colhidos no estádio de maturação I (menos de 15% da superfície da casca amarela. No galpão de embalagem, os frutos passaram por lavagem, seleção, tratamentos hidrotérmico, imersão em fungicida e cera. No laboratório da Universidade Federal Rural do Semi-Árido (Mossoró-RN, os frutos foram armazenados à temperatura de 25º C ± 2º C e umidade relativa de 55% ± 5%. Aos 0; 2; 4; 6; 8 e 10 dias de armazenamento, realizaram-se avaliações sobre as seguintes variáveis: aparência externa e interna, coloração da casca, perda de massa, firmeza, sólidos solúveis, acidez titulável, pH e açúcares. Esse híbrido apresenta características fenotípicas do Grupo Formosa, com frutos alongados, massa média de 1,28 kg, polpa com espessura de 2,74 cm, coloração vermelha e conteúdo elevado de sólidos solúveis (13,65% e açúcares (10,53%.

    The El Paso-Ciudad Juarez metropolitan area obtains its water from the Rio Grande and intermontane-basin aquifers. Shallow ground water in this region is in close communications with the surface water system. A major problem with both systems is salinity. Upstream usage of the water in the Rio Grande for irrigation and municipalities has led to concentration of soluble salts to the point where the surface water commonly exceeds drinking water standards. Shallow ground water is recharged by surface water (primarily irrigation canals and agricultural fields) and discharges to surface water (agricultural drains) and deeper ground water. The source of water entering the Rio Grande varies seasonally. During the irrigation season, water is released from reservoirs and mixes with the return flow from irrigation drains. During the non-irrigation season (winter), flow is from irrigation drains and river water quality is indicative of shallow ground water. The annual cycle can be ascertained from the inverse correlation between ion concentrations and discharge in the river. Water-quality data indicate that the salinity of shallow ground water increases each year during a drought. Water-management strategies in the region can affect water quality. Increasing the pumping rate of water-supply wells will cause shallow ground water to flow into the deeper aquifers and degrade the water quality. Lining the canals in the irrigation system to stop water leakage will lead to water quality degradation in shallow ground water and, eventually, deep ground water by removing a major source of high quality recharge that currently lowers the salinity of the shallow ground water.

    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.

    Full Text Available Diversity of owlet-moth (Lepidoptera, Noctuidae in Salvador do Sul, Rio Grande do Sul, Brazil. The purpose of this paper is to describe the Noctuidae community in Salvador do Sul, Rio Grande do Sul. Light traps captured the insects of this research. The quantitative data were collected through weekly sampling, during one year (1994-1995; the qualitative data were collected through non-systematic sampling, during four consecutive years. The community characterization was based on the richness, abundance, specific constancy, diversity indices and abundance distribution; also total richness estimates were calculated, by nonparametric statistical procedures. In the systematized collecting there were captured 4017 noctuids of 108 species, distributed in 14 subfamilies; in the non-systematized, another 189 additional species and two subfamilies. Amphipyrinae, Hadeninae and Ophiderinae had the largest species richness. The more constant species were noctuids of great economic importance; the accessories were related to specific vegetable groups; the accidentals have their host unknown. The accessories and accidental species were captured more in spring and summer; also in these periods were measured the highest values of richness, abundance and diversity. There was no fit between observed/calculated log normal and log series distribution models. The 2nd order Jackknife and Michaelis-Menten equation procedures estimated that the total richness values were close to the total number of the species in the studied area.

A hipótese é que se originaram dois path dependencies, um dinâmico e outro não, determinados, amplamente, por fatores tecnológicos e pelas matrizes institucionais das duas "metades". Elementos, de larga duração, presentes no percurso original, como direitos de propriedade, aprendizagem, estrutura social, ideologia, hábitos, políticas públicas e inovações, produziram estruturas industriais locais e particulares, capazes de explicar a trajetória de desenvolvimento industrial e o desequilíbrio regional contemporâneo deste estado. A análise evolucionária mostra dois períodos cruciais para o entendimento do desenvolvimento industrial gaúcho: o começo da Primeira República e o início da segunda metade do século XX. Nesses dois momentos, a economia gaúcha encontrava-se em crise, vindo logo em seguida a reestruturar-se. A região responsável pela mudança tecno-produtiva, nos dois períodos, foi a Metade Norte, consolidando-se como matriz industrial dinâmica do Estado do Rio Grande do Sul.This present paper applies both the institutionalistic and neo-Schumpeterian approaches in order to understand the dynamics of industrial development and the consequent evolution of the economic unbalance of the State of Rio Grande do Sul.

    In this work is underlined the potential use of natural gas as main in structural ceramics industry in Rio Grande do Norte. This state is at third place as natural producer in Brazil producing 3,37 millions of m{sub 3}/dia in Guamare fields. The sales of this product reached, in 1999, a volume of 110 mil m{sup 3} / dia for all industrial sector in this state. These number justify, for themselves, the strategic importance in using this fuel in ceramics industrial as a way of introducing new technological basis in production, research and development of this important sector of our economy. At the moment there is a favorable culture and pressure in society to substitute wood by natural gas as main fuel, considering operational advantages, better product quality and environment issues, especially the disaster caused by extensive cutting native vegetation to be used in ceramics processing. It's well known the high levels of losses in wood fired furnaces and ceramics industry as a whole. Experiments using natural gas a main fuel have been carried out in several other states in Brazil as: Rio de Janeiro, Sao Paulo, Santa Catarina and Parana. In Rio Grande do Norte tests have been done in the three main production poles: Potengi, Vale do Acu and Trairi. The out coming intermittent furnaces in processing structural ceramics and it's necessary to build new furnaces or buy industrial ones. Moreover the gas pipeline distribution along coastal line only benefit part of state industry being necessary a significant amount of investments to provide gas to the plants located further away from the pipeline.

A maioria destas propagandas (>80% não apresenta declarações quanto ao nome genérico, à composição, à posologia e ao laboratório fabricante do produto, infringindo, dessa forma, a legislação vigente no país. Além disso, um número significativo das peças publicitárias (39% enfatizam a ausência de quaisquer riscos, mediante declarações como "Não tem contra-indicações", caracterizando a indução ao uso indiscriminado. A análise mostra que os medicamentos são promovidos como produtos quaisquer, omitindo-se informações fundamentais a respeito de cuidados, reações adversas e contra-indicações.Drug advertisements for non-prescription (over-the-counter drugs on the main radio stations in the State of Rio Grande do Sul, Brazil, were analyzed as to the information provided about generic names, pharmaceutical company, composition, and dosage. From August 1995 to January 1996, 250 advertisements for 28 products were recorded. More than 80% of these advertisements provided no information on these topics and thus failed to comply with Brazilian legislation. On the contrary, a large number of advertisements (39% emphasize absence of risks, with claims such as "no contraindications", inducing consumers to use such drugs indiscriminately. The study showed that drugs were advertised like any other merchandise, with no concern over fundamental information such as product identification, precautions, and possible side effects.

    For the first time, a heavy-metal vegetation on top of oxidic and pyritiferous show deposits in the mining areas of Sanga Negra, Seival and Volta Grande. A subtropical mesophytic forest develops in non-metal-containing areas. The following types of vegetation can be discerned on increasing heavy-metal contents: shrub savannah, waste-dump savannah, waste-dump steppe. The physiognomy of these types of vegetation is characterized above all by narrism of woody plants showing xeromorphic configurations frequently. Those plants growing on top of pyritiferous or oxidic ores, resp., showed differences in copper resistance. Anatomical studies of the leaves of Schinus lentiscifolius revealed marked histological changes with an increase of the glandular cells and the oxalate granules were especially noticeable. The following heavy metals were examined in the soils and in the plants: Cu, Pb, Ni, Mo, Ag, Cd. Elements available to plants were established in the soils by three different methods. A number of plants were shown to have relatively high heavymetal contents in their leaves. The feru Dryopteris triphylla showed particularly high contents of lead and silver. The shrub Daphnopsis racemose, however, revealed the highest Cadmium content. Non-linear correlations between the copper contents of soil and plant were found with Schinus lentiscifolius. Certain plants are discussed as to what extent they may be used for bioprospection.

    Full text: Since 1950, terrestrial gravity data of the State of Rio Grande do Sul (RS) have been collected by the Department of Geodesy of the Federal University of Rio Grande do Sul This paper proposes three methods for detecting outliers based on the residue between (M1) data from the digital elevation model of the Shuttle Radar Topography Mission (SRTM) and interpolated observation data of land altimetry surveys conducted; (M2) the interpolated data from the Gravity Recovery and Climate mission Experiment (GRACE) gravity confronting each observation with the observations of the Earth's gravity and (M3) the data relating to each observation Bouguer anomaly calculated and interpolated Bouguer anomalies corresponding. The first method identified 217 points (3.00% of the data) associated with altimetry. The second identified 645 points (8.93% of the data) associated with gravity. The third identified 60 points (0.83% of the data) associated with Bouguer anomaly calculated. The criterion for elimination of observations based on the identification of outliers coincident with at least two methods. The outliers corresponding points between altimetry, gravity and Bouguer anomaly were eliminated from the raw database and totaled 177 points, 2.45% of total bank. From the corrected data, we proceeded to the treatment of integrated analysis of geological validation geophysical information, which was generated by the Bouguer anomaly map of the RS.

    International Nuclear Information System (INIS)

    A survey programme aimed at studying the environmental radioactivity in the Brazilian state of Rio Grande do Norte was undertaken. Fifty-two soil samples, together with two rock and two uraniferrous ore samples were collected from the eastern and central regions of this state. Concentrations of radioelements in samples were determined by γ-ray spectrometry. The average concentrations of 226Ra, 232Th, and 40K in the surveyed soils were 29.2 ± 19.5 (SD), 47.8 ± 37.3, and 704 ± 437 Bq kg-1, respectively. Higher values were found in the rock samples. The distributions of 226Ra and 232Th were fitted by log-normal curves. Radiological measurements carried out with a portable scintillometer at the sampled sites revealed an average absorbed dose rate of 55 ± 27 (SD) nGy h-1. Computed dose rates obtained through the Beck formula ranged from 15-179 nGy h-1, with a mean value of 72.6 ± 38.7 (SD) nGy h-1, and their distribution fitted a log-normal curve. An annual average effective dose equivalent of 552 μSν (range: 117-1361 μSν) was estimated for 51 sites in Rio Grande do Norte. (author)

    Since 1993, the Santa Fe Group aquifer system in the Middle Rio Grande Basin, and particularly in the Albuquerque area, has been the focus of studies to further define the extent of the most productive parts of the aquifer and to gain a better understanding of how ground- water levels are changing over time. The U.S. Geological Survey, in cooperation with the New Mexico Office of the State Engineer, installed nine piezometers during 1998-99 at five sites in and near the margin of the Middle Rio Grande Basin in central New Mexico. In addition, the New Mexico Office of the State Engineer installed another nine piezometers at three sites during 1997. These piezometers allow for collection of ground-water-level data in areas for which little information is available. Most of the piezometers were constructed of 2.5-inch-diameter flush-joint polyvinyl chloride (PVC) schedule 80 casing with 10-foot stainless steel screens; the shallow piezometer at the Tome site has a 40-foot screen, and the single piezometers at the Dome Road and Phoenix Road sites have steel casing with welded joints and a 10- and a 20-foot screen, respectively. Steel casing with a locking lid covers the uppermost 2 feet of the piezometer casing. Drillers' logs and petrophysical logs were collected from the deepest borehole at each site.

    There are limited studies in Puerto Rico that shows the water resources availability and variability with respect to changing climates and land use. The main goal of the HICE-PR (Human Impacts to Coastal Ecosystems in Puerto Rico (HICE-PR): the Río Loco Watershed (southwest coast PR) project which was funded by NASA is to evaluate the impacts of land use/land cover changes on the quality and extent of coastal and marine ecosystems (CMEs) in two priority watersheds in Puerto Rico (Manatí and Guánica).The main objective of this study is to set up a physically based spatially distributed hydrological model, Soil and Water Assessment Tool (SWAT) for the analysis of hydrological processes in the Rio Grande de Manati river basin. SWAT (soil and water assessment tool) is a spatially distributed watershed model developed to predict the impact of land management practices on water, sediment and agricultural chemical yields in large complex watersheds. For efficient use of distributed models for hydrological and scenario analysis, it is important that these models pass through a careful calibration and uncertainty analysis. The model was calibrated and validated using Sequential Uncertainty Fitting (SUFI-2) calibration and uncertainty analysis algorithms. The model evaluation statistics for streamflows prediction shows that there is a good agreement between the measured and simulated flows that was verified by coefficients of determination and Nash Sutcliffe efficiency greater than 0.5.

    Full Text Available Molecular findings that confirmed the participation of ovine herpesvirus 2 (OVH-2 in the lesions that were consistent with those observed in malignant catarrhal fever of cattle are described. Three mixed-breed cattle from Rio Grande do Norte state demonstrated clinical manifestations that included mucopurulent nasal discharge, corneal opacity and motor incoordination. Routine necropsy examination demonstrated ulcerations and hemorrhage of the oral cavity, corneal opacity, and lymph node enlargement. Significant histopathological findings included widespread necrotizing vasculitis, non-suppurative meningoencephalitis, lymphocytic interstitial nephritis and hepatitis, and thrombosis. PCR assay performed on DNA extracted from kidney and mesenteric lymph node of one animal amplified a product of 423 base pairs corresponding to a target sequence within the ovine herpesvirus 2 (OVH-2 tegument protein gene. Direct sequencing of the PCR products, from extracted DNA of the kidney and mesenteric lymph node of one cow, amplified the partial nucleotide sequences (423 base pairs of OVH-2 tegument protein gene. Blast analysis confirmed that these sequences have 98-100% identity with similar OVH-2 sequences deposited in GenBank. Phylogenetic analyses, based on the deduced amino acid sequences, demonstrated that the strain of OVH-2 circulating in ruminants from the Brazilian states of Rio Grande do Norte and Minas Gerais are similar to that identified in other geographical locations. These findings confirmed the active participation of OVH-2 in the classical manifestations of sheep associated malignant catarrhal fever.

Methods: The bibliometric study was conducted with undergraduate final research projects from five courses in Nutrition in the state of Rio Grande do Norte during 2013 and 2014. The following variables were collected: institution, title of project, number of authors, academic degree of the advisor, study design, area of study interest, type of study, study setting, submission to the ethics committee, and keywords. Pearson's Chi-square test was used to assess the variable area of study interest with a significance level at p≤0.05 and 95% confidence interval. Results: Of the 195 projects analyzed, 79.0% were developed at universities. We found a higher frequency of academic articles (68.2% developed by a single student (65.6%, advised by a professor with a Masters degree (57.9%, with a cross-sectional study design (48.2%, and without submission to the research ethics committee (49.2%. The mean adequacy of keywords was 50.0%. Conclusion: The quantitative approach was the most predominant characteristic of the final research projects and the most frequently researched area of knowledge was public health. The methodological approaches of the research projects were considered weak, which suggests the need to improve the quality of scientific methodology during undergraduate studies, considering the important benefits derive from researches as an active methodology.

    Full Text Available Rio Grande do Sul was the first Brazilian state to plant genetically modified soybean. The sowing occurred in 1998 with Roundup Ready soybean seeds from Monsanto smuggled from Argentina. The aim of this study is to investigate how this innovative process of planting transgenic soybean came about in Rio Grande do Sul based on the actor network involved in the period 1998 to 2003. Although the innovative process has been discussed in the literature on innovation management since the work of Schumpeter, there is still no clear understanding of the issues of interests and power that involve the innovative process. Given this, from within the literature we have sought a perspective that would understand the innovative process as being political. We adopted Actor Network Theory as a base for the discussion of the primary and secondary data obtained regarding the controversy surrounding transgenic soybean in RS. The results point to the existence of two translation chains that contribute towards the formation of actor networks.

    Full Text Available This research evaluates the degree of difficulty (and their nature to perform the steps of the news products development process (PDP in the dairy industry of Rio Grande do Sul state, Brazil. A descriptive/ quantitative survey was performed with decision makers from 68 dairy processing industries in the state of Rio Grande do Sul which are under federal or state sanitary supervision. Considering all steps of PDP, about 40% of the problems were related with management issues against 20% with financial, 20% commercial and 20% of a technological nature. In particular, the steps of the PDP in which the decision makers of the companies surveyed have more difficult were related to “testing of prototypes – exploring new ingredients and packages”, “the definition of suppliers” in the development phase, and the “study of shopping behavior and consumers attitudes”, after launching the new product. These difficulties may be related to a change in the profile of the innovations developed in this sector, with a lower dependence on suppliers and a greater appropriability concern – which requires greater technical skills and a more aligned vision among “production” and “management” staff.

The marked differences in precipitation could impair the quality of water; therefore the aim of this study was to establish the relationship between the ions and their location in the graph: relationship of ions and mechanisms of chemical processes, water behavior and trend setting. The study was a non-experimental, cross-sectional and descriptive research. 111 samples were collected in the group of channels that form the Rio Grande basin, in 2013 and 2014 during times of drought and rain. The parameters were measured in the sample anions and cations. The processes that control the chemistry of surface water in the studied area during the rainy season have a predisposition to mineralization in equilibrium with rocks. However, in the time of drought, water movement was observed towards the area where evaporation with respect to precipitation predominates, increasing the inorganic chemistry of the waters that, in time, could be extended.

    2008-12-01

    In the southwest United States, the majority of the usable water resources come from melted snow in the Rocky Mountains. Specifically, in New Mexico, the San Juan Mountains in southern Colorado contribute much of the snowpack that forms spring and summer river flows in the tributaries of the Rio Grande. The analysis of mountain snowpack is often done with a combination of ground-based instruments and remote sensing instruments on orbiting platforms. Terrain and weather issues make continuous, accurate measurement of water content difficult as it is impractical to take a multitude of ground measurements to attain information on snow-covered area (SCA) and snow-water equivalent (SWE). A project is underway to use established techniques to determine sub- pixel resolution of SCA for an eight-year dataset from 2000 to 2008. Archived and live satellite data from NASA's Moderate Resolution Imaging Spectro-Radiometer (MODIS) will be the primary source of remote sensing information for determining SWE through the early, peak and late season snowpack found in southern Colorado. The final results for SWE will be compared with river gauge data obtained from the US Geological Survey will determine an efficiency rating of snowpack to usable freshwater in the Rio Grande, in addition to lag time between peak snowpack and peak river discharge.

    Fasciola hepatica is the causative agent of fasciolosis, a disease that triggers a chronic inflammatory process in the liver affecting mainly ruminants and other animals including humans. In Brazil, F. hepatica occurs in larger numbers in the most Southern state of Rio Grande do Sul. The objective of this study was to estimate areas at risk using an eight-year (2002-2010) time series of climatic and environmental variables that best relate to the disease using a linear regression method to municipalities in the state of Rio Grande do Sul. The positivity index of the disease, which is the rate of infected animal per slaughtered animal, was divided into three risk classes: low, medium and high. The accuracy of the known sample classification on the confusion matrix for the low, medium and high rates produced by the estimated model presented values between 39 and 88% depending of the year. The regression analysis showed the importance of the time-based data for the construction of the model, considering the two variables of the previous year of the event (positivity index and maximum temperature). The generated data is important for epidemiological and parasite control studies mainly because F. hepatica is an infection that can last from months to years. PMID:26827853

    As the finite, and often over-allocated water resources of the western United States are challenged by a myriad of growing demands, computer based simulations can be a powerful tool for evaluation of potential water use scenarios for hydrologic decision making and water policy analysis. To maximize their usefulness for policy analysis, such simulations should accurately represent the physical system as well as its interconnectedness to the socio-economic systems relevant to water planning without losing user accessibility or run speed. One solution to these constraints is system dynamics (SD) modeling at a relatively coarse spatial and temporal resolution. The challenge of this approach is in maintaining sufficient physical accuracy despite coarse resolution and SD's simple modeling framework. In this paper, the development of a reach-based monthly time-step system dynamics model of the upper Rio Grande River (from the headwaters in Colorado to Elephant Butte Reservoir in New Mexico) is discussed. Within this SD model, temporally and spatially coarse physical and operational relationships are abstracted from a variety of existing models with higher resolutions, including an operations model (Upper Rio Grande Water Operations Model (URGWOM)), a land surface rainfall-runoff model, an evapotranspiration model, and two groundwater models. Abstraction and calibration methods and implications of information loss associated with this scaling are considered.

    Full Text Available Descrevem-se dois surtos de intoxicação por Senecio madagascariensis Poir. diagnosticados em bovinos em outubro de 2013 na região sul do Rio Grande do Sul. A morbidade foi de 3,2% e de 6,1% respectivamente e a letalidade foi de 100%. Um terceiro caso da intoxicação ocorreu em uma propriedade na qual de 54 bovinos um morreu com sinais clínicos da intoxicação. Em todos os casos, os bovinos estavam em áreas altamente infestas por S. madagascariensis que se encontrava em floração. Os sinais clínicos caracterizaram-se por diarreia, tenesmo, opistótono e emagrecimento progressivo e a morte ocorreu entre 10 e 15 dias após o início dos sinais clínicos. Nas necropsias as lesões eram de edema do mesentério, das paredes do abomaso e do rúmen, e das paredes da vesícula biliar, além de fígado firme e com aspecto marmorizado. Histologicamente havia no fígado proliferação de tecido conjuntivo fibroso, principalmente nos espaços porta, megalocitose e hiperplasia de ductos biliares. A observação de grande quantidade de S. madagascariensis em várias propriedades nos municípios de Arroio Grande, Pedro Osório e Capão do Leão a partir do ano 2013 sugere que esta planta está em pleno processo de adaptação e disseminação nesta região e que outros surtos podem ocorrer nos próximos anos. Os surtos relatados aparentemente resultaram do consumo da planta durante o outono/inverno de 2013, quando a mesma estava já em floração. A quantificação dos alcaloides revelou a presença de 500 µg/g e 4000µg/g de planta seca de alcaloides pirrolizidínicos em duas das três propriedades com casos de seneciose. Acredita-se que a grande quantidade de planta existente nas áreas onde os animais estavam e a quantidade de alcaloides presentes na mesma foram fatores que determinaram a ocorrência dos surtos.

    The sustainable management of water resources in a river basin requires an integrated analysis of the social, economic, environmental and institutional dimensions of the problem. Numerical models are commonly used for integration of these dimensions and for communication of the analysis results to stakeholders and policy makers. The National Science Foundation Science and Technology Center for Sustainability of semi-Arid Hydrology and Riparian Areas (SAHRA) has been developing integrated multi-resolution models to assess impacts of climate variability and land use change on water resources in the Rio Grande Basin. These models not only couple natural systems such as surface and ground waters, but will also include engineering, economic and social components that may be involved in water resources decision-making processes. This presentation will describe the conceptual framework being developed by SAHRA to guide and focus the multiple modeling efforts and to assist the modeling team in planning, data collection and interpretation, communication, evaluation, etc. One of the major components of this conceptual framework is a Conceptual Site Model (CSM), which describes the basin and its environment based on existing knowledge and identifies what additional information must be collected to develop technically sound models at various resolutions. The initial CSM is based on analyses of basin profile information that has been collected, including a physical profile (e.g., topographic and vegetative features), a man-made facility profile (e.g., dams, diversions, and pumping stations), and a land use and ecological profile (e.g., demographics, natural habitats, and endangered species). Based on the initial CSM, a Conceptual Physical Model (CPM) is developed to guide and evaluate the selection of a model code (or numerical model) for each resolution to conduct simulations and predictions. A CPM identifies, conceptually, all the physical processes and engineering and socio

  1. A multi-dimensional analysis of the upper Rio Grande-San Luis Valley social-ecological system

    Mix, Ken

    The Upper Rio Grande (URG), located in the San Luis Valley (SLV) of southern Colorado, is the primary contributor to streamflow to the Rio Grande Basin, upstream of the confluence of the Rio Conchos at Presidio, TX. The URG-SLV includes a complex irrigation-dependent agricultural social-ecological system (SES), which began development in 1852, and today generates more than 30% of the SLV revenue. The diversions of Rio Grande water for irrigation in the SLV have had a disproportionate impact on the downstream portion of the river. These diversions caused the flow to cease at Ciudad Juarez, Mexico in the late 1880s, creating international conflict. Similarly, low flows in New Mexico and Texas led to interstate conflict. Understanding changes in the URG-SLV that led to this event and the interactions among various drivers of change in the URG-SLV is a difficult task. One reason is that complex social-ecological systems are adaptive, contain feedbacks, emergent properties, cross-scale linkages, large-scale dynamics and non-linearities. Further, most analyses of SES to date have been qualitative, utilizing conceptual models to understand driver interactions. This study utilizes both qualitative and quantitative techniques to develop an innovative approach for analyzing driver interactions in the URG-SLV. Five drivers were identified for the URG-SLV social-ecological system: water (streamflow), water rights, climate, agriculture, and internal and external water policy. The drivers contained several longitudes (data aspect) relevant to the system, except water policy, for which only discreet events were present. Change point and statistical analyses were applied to the longitudes to identify quantifiable changes, to allow detection of cross-scale linkages between drivers, and presence of feedback cycles. Agricultural was identified as the driver signal. Change points for agricultural expansion defined four distinct periods: 1852--1923, 1924--1948, 1949--1978 and 1979

    The hydro-physical opportunities for expanding the beneficial uses of the fixed water supply in the Rio Grande/Bravo Basin to better satisfy an array of water management goals are examined. These include making agriculture more resilient to periodic conditions of drought, improving the reliability of supplies to cities and towns, and restoring lost environmental functions in the river system. This is a comprehensive, outcome-neutral, model- based planning exercise performed by some 20 technical, primarily non-governmental institutions from both countries, aimed at proposing strategies that can reduce future conflicts over water throughout the entire basin. The second track consists in generating a set of future water management scenarios that respond to the needs and objectives of the basin stakeholders in each segment and each country. An array of scenarios for improved water management has been developed for the lower Rio Grande/Rio Bravo basin in Texas and the Mexican state of Tamaulipas. Another set under development will focus on the Rio Conchos and the El Paso/Juarez region. Eventually, scenarios will be generated such that will comprehend the entire basin on both sides of the border. These scenarios are the product of consultations with agricultural water districts, governmental organizations and environmental NGOs. They include strategies for reducing the physical losses of water in the system, conservation transfers, improvements in the operations of the Mexican and international reservoirs, improvements in environmental flow conditions, improvements in reliability of water supplies, and drought coping strategies.These scenarios will be evaluated for hydrologic feasibility by the basin-wide model and the gaming exercises. Modeling is necessary to understand how these options will affect the entire system and how they can be crafted to maximize the benefits and avoid unintended or uncompensated effects. The scenarios that have the potential to provide large

    In the Southwest US, the southern Rocky Mountains provide a significant orographic barrier to prevailing moisture-laden Westerly winds, which results in snow accumulation and melt, both vitally important to the region’s water resources. The inherent variability of meteorological conditions in the Southwest, during both snowpack buildup and depletion, requires improved spatially-distributed data. The population of ground-based networks (SNOTEL, SCAN, and weather stations) is sparse and does not satisfactorily represent the variability of snow accumulation and melt. Remote sensing can be used to supplement data from ground networks, but the most frequently available remotely sensed product with the highest temporal and spatial resolution, namely snow cover, only provides areal data and not snow volume. Fortunately, the Snowmelt Runoff Model(SRM), which was developed in mountainous regions of the world, including the Rio Grande basin, accepts snow covered area as one of its major input variables along with temperature and precipitation. With the growing awareness of atmospheric warming and the southerly location of Southwest watersheds, it has become apparent that the effects of climate change will be especially important for Southwestern water users. The NSF-funded EPSCoR project “Climate Change Impacts on New Mexico’s Mountain Sources of Water” (started in 2009) has focused on improving hydrometeorological measurements, developing basin-wide and sub-basin snow cover mapping methods, generating snowmelt runoff simulations, forecasts, and long-term climate change assessments, and informing the public of the results through outreach and educational activities. Five new SNOTEL and four new SCAN sites are being installed in 2009-2010 and 12 existing basic SNOTEL sites are being upgraded. In addition, 30 automated precipitation gages are being added to New Mexico measurement networks. The first phase of snow mapping and modeling has focused on four sub basins

    Twenty-four piezometers were installed from mid-October 1984 to mid-January 1985 in two sections of the Rio Grande valley near Albuquerque, New Mexico. Each cross section is comprised of four piezometer nests and each nest is comprised of three piezometers completed at different depths. The purpose of this report is to describe the piezometers nests and present some of the water level data collected from the piezometers. The piezometers were drilled using the hydraulic rotary method. The piezometers were completed with 5 feet of 60-slot wire-wound stainless steel well screen and flush joint PVC well casing. The description of each piezometer nest consists of the location of the particular piezometer nest; a figure showing the location, depth altitude, and station identification number of the piezometers in each nest; and a driller 's log, geophysical logs, and description of the well cuttings from the deepest borehole in each piezometer nest. Water level altitudes generally increased from February until June 1985 in the piezometers in the Rio Bravo section. Water level altitudes in piezometers completed at different depths in a particular nest are about the same in all of the Rio Bravo nests and in the Montano 1 nest. In several of the piezometer nests, especially the Montano nests, water level altitudes decrease with depth. (USGS)

    Full Text Available A review of published papers and results of analysis of new material have allowed improvements on the palynostratigraphy of the Permian strata of the Paraná Basin in Rio Grande do Sul State. Based on first and last occurrences of certain species of pollen taxa, two palynozones are formalized, these are the Vittatina costabilis and Lueckisporites virkkiae Interval Zones, in ascending order. The Vittatina costabilis Interval Zone is subdivided into two units, in ascending order the Protohaploxypinus goraiensis and the Hamiapollenites karrooensis Subzones, and is recognized from the glacial (Itararé Group and post-glacial sequence (Rio Bonito Formation and the base of the Palermo Formation. The Lueckisporites virkkiae Interval Zone occurs from the uppermost Rio Bonito Formation, through the Palermo and Irati formations, and into the Serra Alta and Teresina formations. The main characteristics and reference sections are established, as well as additional criteria to recognize biostratigraphical units, in accordance with the International Stratigraphic Guide. Palynostratigraphical correlation suggests that the Vittatina costabilis Zone concerns the Early Permian (early Cisuralian, while the Lueckisporites virkkiae is regarded as late Early Permian to early Middle Permian (late Cisularian to early Guadalupian.

  14. Polychlorinated Biphenyls (PCBs) in Catfish and Carp Collected from the Rio Grande Upstream and Downstream of Los Alamos National Laboratory: Revision 1

    2008-05-12

    Concern has existed for years that the Los Alamos National Laboratory (LANL), a complex of nuclear weapons research and support facilities, has released polychlorinated biphenyls (PCBs) to the environment that may have reached adjacent bodies of water through canyons that connect them. In 1997, LANL's Ecology Group began measuring PCBs in fish in the Rio Grande upstream and downstream of ephemeral streams that cross LANL and later began sampling fish in Abiquiu and Cochiti reservoirs, which are situated on the Rio Chama and Rio Grande upstream and downstream of LANL, respectively. In 2002, we electroshocked channel catfish (Ictalurus punctatus) and common carp (Carpiodes carpio) in the Rio Grande upstream and downstream of LANL and analyzed fillets for PCB congeners. We also sampled soils along the Rio Chama and Rio Grande drainages to discern whether a background atmospheric source of PCBs that could impact surface water adjacent to LANL might exist. Trace concentrations of PCBs measured in soil (mean = 4.7E-05 {micro}g/g-ww) appear to be from background global atmospheric sources, at least in part, because the bimodal distribution of low-chlorinated PCB congeners and mid-chlorinated PCB congeners in the soil samples is interpreted to be typical of volatilized PCB congeners that are found in the atmosphere and dust from global fallout. Upstream catfish (n = 5) contained statistically (P = 0.047) higher concentrations of total PCBs (mean = 2.80E-02 {micro}g/g-ww) than downstream catfish (n = 10) (mean = 1.50E-02 {micro}g/g-ww). Similarly, upstream carp (n = 4) contained higher concentrations of total PCBs (mean = 7.98E-02 {micro}g/g-ww) than downstream carp (n = 4) (3.07E-02 {micro}g/g-ww); however, the difference was not statistically significant (P = 0.42). The dominant PCB homologue in all fish samples was hexachlorobiphenyls. Total PCB concentrations in fish in 2002 are lower than 1997; however, differences in analytical methods and other uncertainties

A cross-sectional study was performed from March to September 2002 in a representative sample of adolescents 15 to 18 years of age in the urban area of Pelotas, Rio Grande do Sul State, Brazil. Multiple-stage sampling was used, and in the 448 census tracts located in the urban area, 90 were sampled and households were visited in each tract. Information was collected on sexual initiation and use of contraceptive methods. Chi-square test was used to compare proportions. The sample included 960 adolescents. 88% of subjects reported the use of any contraceptive method. Condoms were the most commonly used method (63.2%. Low adolescent schooling was the only variable associated with increased risk of non-use of contraceptives. Condom use was higher among males, adolescents whose mothers had 9 or more years of schooling, and those reporting several sexual partners in the previous year. Condoms were the most commonly used contraceptive method.O estudo avaliou o uso de métodos contraceptivos em adolescentes.

    Full Text Available Nos solos cultivados com arroz irrigado por alagamento no Estado do Rio Grande do Sul, a maior fração do P inorgânico está ligada a óxidos de Fe. Espera-se que um extrator que tenha a capacidade de extrair o P adsorvido a estes óxidos possa ser mais eficiente para avaliar a disponibilidade de P para as plantas de arroz. Considerando o exposto, realizou-se um experimento, em casa de vegetação, com amostras de cinco solos do Rio Grande do Sul com o objetivo de avaliar a disponibilidade de P no solo para o arroz. Foram testados os seguintes métodos: Mehlich-1, Mehlich-3, resina de troca aniônica em lâminas, Olsen e P-oxalato a pH 6. Os solos foram previamente incubados com três doses de P na forma de superfosfato triplo e, posteriormente, cultivados com arroz, em condições reduzidas, durante 38 dias. Os coeficientes de determinação obtidos entre o P acumulado pelas plantas de arroz e o P extraído dos solos foram: 0,83* para o Mehlich-1, 0,81* para o Mehlich-3, 0,88* para a resina de troca, 0,85* para o Olsen e 0,59* para o P-oxalato. A separação dos solos em dois grupos segundo o material de origem e os teores de óxidos de Fe de baixa cristalinidade, extraídos com oxalato a pH 6, resultou em melhor eficiência dos métodos testados para avaliar a disponibilidade do P para o arroz.In the paddy rice soils in the of Rio Grande do Sul State, Brazil, most inorganic P is bound to Fe oxides.

    The Rio Grande and its tributaries represent a critical water source for both the human population and the ecological resources of the Rio Grande drainage basin. Manadas Creek, an urban tributary of the Rio Grande, is located in an industrialized area of Laredo, Texas, where warehouses, a major railroad, and a decommissioned antimony (Sb) smelter are located. Previous studies have found that the creek water is contaminated with heavy metals such as Sb and arsenic (As). However, data on the metal distribution in this creek are very limited. Herein, water and sediment core samples were collected from six sites along the creek in February, April, and May 2008. Samples were analyzed for dissolved and total metals in water, total metals in sediments, and available (soluble-exchangeable, surface adsorbed, and organically bound) fractions of metals associated with the sediments. Results show that concentrations of Sb in the water and sediment samples were significantly lower at the upstream control site compared to the two sites located near the decommissioned smelter. Decreasing levels of Sb were found at the sites located downstream. The As levels in the sediment remained constant at different depths, whereas Sb varied significantly. A high level, 420 mg/kg, of sediment Sb was found at the maximum sediment depth of 35.0 cm sampled. In addition, 65.7-76.9% Sb and 80.3-85.6% As were in their residual form, 15.0-22.5% Sb and 6.2-11.4% As were bound to organic matter, and the remaining As and Sb were in the soluble and surface adsorbed fractions. Pearson correlation analyses indicated that the distribution of Sb was only moderately correlated to iron and nickel in the sediment and its correlation with the sediment properties measured was insignificant. Cluster analyses only grouped the two Sb isotopes together for the sediments collected in May, indicating that sources other than natural occurrence were associated with Sb. The high level of sediment Sb observed indicates

Em seguida, através da estimação de um modelo de regressão censoriada (Tobit determinou-se a associação dos escores de eficiência com indicadores de gestão dos carcinicultores e a localização de suas fazendas. Os níveis de eficiência técnica foram mais altos para os sistemas de produção extensivo e semi-intensivo. Os resultados também revelaram que algumas práticas de gestão estão associadas aos escores de eficiência. Além disso, produtores localizados em estuários com menores níveis de emissões de nitrogênio e fósforo e, portanto, menos poluentes na média, obtiveram melhor eficiência técnica, ou seja, o melhor uso dos recursos de produção conecta-se a um menor impacto ambiental da atividade sobre os estuários do estado.This paper investigates shrimp small and median farms performance in Rio Grande do Norte in two steps. First, technical efficiency was estimated by nonparametric production frontiers, data envelopment analysis (DEA and Free Disposal Hull (FDH. As a second stage, after DEA and FDH analysis, the degree of inefficiency was explained by a statistical Tobit model, in terms of managerial indicators and localization. Average efficiencies were bigger for the extensive and semi-intensive production system. The results indicated that some managerial practices did not reduce the inefficiency. The localization affected inefficiency: producers within estuaries associated with the emissions of small amounts of nitrogen and phosphorus were efficient, i.e., a best use of inputs can reduce environmental impacts.

  20. Hydrologic budget of the late Oligocene Lake Creede and the evolution of the upper Rio Grande drainage system

    Barton, Paul B.; Steven, Thomas A.; Hayba, Daniel O.

    2000-01-01

    The filling history, hydrologic budget, and geomorphic development of ancient Lake Creede and its tributary basin are evaluated to determine the factors that controlled its character. The lake filled the Creede caldera that formed in the late Oligocene as a consequence of the eruption of the Snowshoe Mountain Tuff. The caldera's sedimentary fill accumlated to a depth of about 1.26 km and had a volume of about 89 km3. The highest lake level was ~3300 m (10,800 ft) present altitude before it drained eastward across a broad volcanic plateau as the ancestral Rio Grande. A tributary canyon several hundred meters deep was cut into hard rhyolite in the north wall of the caldera before the lake was more than half full; its presence demonstrates that ancient Lake Creede filled slowly and thus occupied a long-lived, closed basin. The slow filling rate is incompatible with the present water flux through the Creede caldera basin, because such a flow would fill the basin geologically instantaneously. This mismatch, together with the recognition that the Oligocene climate was similar to that of today, forces the reexamination of the hydrologic and geomorphic history of the caldera. That appraisal shows that the caldera cannot have resurged rapidly immediately after caldera collapse, and that ancient watershed must have been lass than half as large as the present upper Rio Grande basin. The ancient lake had a more or less constant surface area of about 200 km2 that approximated a steady-state condition between inflow and evaporation. Although the lake level fluctuated with climatic variations, its surface elevation steadily climbed as sediment accumulated, accelerating as resurgance and dome growth usurped spacewithin the basin. It could have had one playa stage early in its development and another after the basin had nearly filled with sediment, but there is no direct evidence for either. At least the lower half of the sedimentary column (the part sampled by the scientific

    In the mountainous American Southwest, the Rio Grande basin is a prime example of how conflicts, misconceptions, and competition regarding water can arise in arid and semi-arid catchments. Much of the Rio Grande runoff originates from snow fields in the San Juan Mountains of southern Colorado and the Sangre De Cristo Mountains of northern New Mexico, far from population centers. Large and rapidly growing cities, like Albuquerque, Las Cruces, El Paso, and Juarez, are located along the Rio Grande where it flows through the Chihuahuan Desert, the largest desert in North America(two NSF Long Term Ecological Research sites are located in the desert portion of the basin). As a result, the importance of snowmelt, which makes up 50-75% or more of the total streamflow in sub-basins above Elephant Butte Reservoir(in south central New Mexico) is hardly known to the general public. Streamflow below Elephant Butte Reservoir is rainfall driven and very limited, with the lower basin receiving only 170-380 mm of precipitation annually, most of it occurring during the months of July-September. Extreme events, such as drought and flooding, are not unusual in arid basins, and they are of increasing concern with regard to changes in frequency of such events under the impending conditions of climate change. Current water demands in the basin already exceed the water supply by 15% or more, so streamflow forecasts(especially from snowmelt runoff) are extremely valuable for efficient water management as well as for proper apportionment of water between Colorado, New Mexico, and Texas under the Rio Grande Compact of 1938 and between the U.S. and Mexico under the Treaty of 1906. Other demands on the water supply include Indian water rights, flood regulation, irrigated agriculture, municipal and industrial demands, water quality, riverine and riparian habitat protection, endangered and threatened species protection, recreation, and hydropower.

    Full Text Available Abstract This study was conducted in four strains of Aedes aegypti mosquitoes to evaluate the enzymatic activity profiles in the city of Mossoró, Rio Grande do Norte, and correlate them with biochemical mechanisms of resistance to insecticides. Mosquitos were used to quantify the following detoxification enzymes: Mixed-Function Oxidase (MFO, PNPA-esterase (PNPA-EST, and Acetylcholinesterase (AChE. The profiles were compared statistically with profiles from the Rockefeller strain, through the Kruskal-Wallis test and Dunn's multiple comparisons (p 15% and 50%. The statistical analysis revealed significant differences in the MFO and AChE profiles, which are fundamental in the determination of profiles of resistance to insecticides. Three populations were classified as “Substantially changed” for MFO. The altered enzymatic activity showed that the changes could have an important role in exposing resistance to insecticides.

    The scope of this study was to identify socioeconomic contextual and health care factors in primary care associated with maternal near misses and their marker conditions. This is an ecological study that used aggregated data of 63 clusters formed by the municipalities of State of Rio Grande do Norte, Brazil, using the Skater method of area regionalization, as the unit of analysis. The ratio of maternal near misses and their marker conditions were obtained from the Hospital Information System of the Brazilian Unified Health System. In multiple linear regression analysis, there was a significant association between maternal near misses and variables of poverty and poor primary health care. Hypertensive disorders were also associated with poverty and poor primary care and the occurrence of hemorrhaging was associated with infant mortality. It was observed that the occurrence of maternal near misses is linked to unfavorable socioeconomic conditions and poor quality health care that are a reflection of public policies that accentuate health inequalities.

    Full Text Available The north littoral region of Rio Grande do Sul is a coastal zone segment where a sequence of environments organized in a longitudinal orientation to the coast occurs. A sedimentary coastal plain is identified landwards from the shoreline, formed by dunes deposits and by interconnected coastal lagoons, and extending its area up to the scarps of the Planalto Meridional (basement highlands, which are deeply incised by the valleys of Maquiné and Três Forquilhas rivers. The relationships between society and nature have increased in the last decades, in special in the Coastal Zone, due to the urbanizationprocesses, among other factors. However, the quick grow of urbanization resulted in some problems for an environment that is characterized by an ecosystem diversity of great sensibility. The analysis of the index of social-economic development allows classifying the north littoral region of Rio Grande do Sul in a profile of a medium development rate. The investments on healthy and education of the last years have increased the regional socio-economical indicators. However, more investments are necessary in key-sectors of the study area, mainly in respect to: the demand for high school opportunities, availability of water by a general net, collection and discharge of urban effluents and waste disposal. The most significant environmental changes, increased during summer months (December to March, are related to the high demand and quality of waters, the high demand for healthy services, beach quality, sanitarycollapse, disposal of residual solids, conflicts on the use of the beach area, increase on the number of irregular properties, water, sound and visual pollution, a general lack of respect to the environment,among others.

  16. Assessment of major and trace elements in sediment samples from Billings Dam, Rio Grande reservoir, by neutron activation analysis

    International Nuclear Information System (INIS)

    The Rio Grande Reservoir, Southeast of the Sao Paulo Metropolitan Area (SPMA), supplies water for four counties (Sao Bernardo do Campo, Sao Caetano do Sul, Santo Andre and Diadema). It has been seriously affected by urban expansion, due to chaotic urban occupation and improper use of the surrounding areas. In this study cores and bottom sediment samples were collected, by using a piston corer and Van Veen samplers, respectively, during the dry season (May to August, 2004). The Van Veen sampler collected 3 samples of 50 cm from each other in a triangle around the point where the piston corer sample was collected. These 3 samples constituted a composed sample. Each of the four piston corer samples were sliced resulting in 4 samples each: 0-5, 5-10, 10-20 and 20-30 cm deep. Four sampling points were defined by using a GPS and are located at the mouth of Rio Grande and Ribeirao Pires Rivers (discharge of contaminants - point 4), in the middle of the reservoir (points of depuration - point 3 and 2) and near the catchment point of the water supply (point 1). The sediment samples were submitted to instrumental neutron activation analysis and the following elements were determined: As, Ba, Br, Co, Cr, Cs, Fe, Na, Rb, Sb, Sc, Se, Ta, Th, U e Zn and the rare earth elements Ce, Eu, La, Lu, Nd, Sm, Tb, Yb. The methodology validation was carried out by certified reference material analyzes. As for the results obtained for these elements in the core samples, there was a significant variation concentration in the four sampling points, mainly for As and Cr at point 1. When we compared these values with ISQL and PEL from Environmental Canada (Canadian Sediment Quality Guidelines) we observed that As and Cr levels are above PEL and TEL values, indicating a strong anthropogenic contribution. For the other sampling points high concentration values were observed for the majority of the elements analyzed as well. (author)

    Full Text Available The aim of this study is to identify factors that relate to the judgment of political parties accountability operating in the state of Rio Grande do Norte. Twenty-four political parties with directory in the state were selected considering those who have had their accounts judged between 2006 to 2013. In order to determine which factors are related to the trial of party accounts, logistic regression were considered for the analysis. Independent variables were the total revenues received by the party (in logarithm, dummy for political parties with or without the resources of the party fund and dummy for years that there were state elections, while the trial of the accounts of parties (approval / disapproval is dependent variable. The results show that only the dummy's Party Fund positively influence the judgments of the annual accounts parties. Thus, it is understood that the parties receiving public funds are more likely to provide better information and, therefore, have its accounts approved by the Unidade Técnica do Tribunal Regional Eleitoral do Rio Grande do Norte. Moreover, one can even say that the parties receiving such government help have a trend or an indication of concern with the concept of accountability, since the party fund is a public resource. It is recommended that future studies address other indicators, for example, liquidity, debt and profitability. Moreover, as also proxies related to the disclosure of financial statements, number of persons elected by party in relation to the number of candidates and party members number could become plausible indicators for future research that would use the same methodology. In addition, replicate this metodology to other states for comparative issues, and even use the same methodology at national level could be aspects of research to be worked for the future.

    Accumulation of 12 trace elements by transplanted aquatic bryophytes (Hygrohypnum ochraceum) was determined at 13 sites in the Rio Grande and tributary streams in southern Colorado and northern New Mexico as part of the US Geological Survey`s National Water-Quality Assessment Program. The purposes of the study were to determine the spatial distribution of trace elements in relation to land-use practices in the upper Rio Grande Basin, compare accumulation rates of metals in bryophytes at sites contaminated by trace elements, and evaluate transplanted aquatic bryophytes as a tool for examining the bioavailability of trace elements in relation to concentrations in water and bed sediment. Concentrations of Cd, Cu, Pb, and Zn in bryophytes, water, and bed sediment were significantly higher at sites that receive drainage from mining areas than at sites near agricultural or urban activities. Concentrations of most trace elements were lower in a tributary stream below an urban source than at sites near mining or agricultural use. Concentrations of Cu and Zn in bryophytes correlated with concentrations in water and bed sediment. In addition, bryophyte concentrations of As, Cd, and Pb correlated with concentrations in bed sediment. Transplanted bryophytes can provide an indication of bioavailability. Rates of accumulation were related to the magnitude of ambient trace-element concentrations; maximal uptake occurred during the first 10 d of exposure. Trace-element concentrations in transplanted bryophytes could potentially be used to predict water and sediment concentrations that represent an integration of conditions over short to intermediate lengths of time, rather than instantaneous conditions as measured using water samples.

  19. Mass movements in the Rio Grande Valley (Quebrada de Humahuaca, Northwestern Argentina: a methodological approach to reduce the risk

    Full Text Available Slope processes such as slides and debris flows, are among the main events that induce effects on the Rio Grande sediment transport capacity. The slides mainly affect the slope of the Rio Grande river basin while debris and mud flows phenomena take place in the tributary valleys. In the past decades several mass movements occurred causing victims and great damages to roads and villages and therefore hazard assessment and risk mitigation is of paramount importance for a correct development of the area. This is also an urgent need since the Quebrada de Humahuaca was recently included in the UNESCO World Cultural Heritage. The growing tourism business may lead to an uncontrolled urbanization of the valley with the consequent enlargement of threatened areas.

    In this framework mitigation measures have to take into account not only technical aspects related to the physical behaviour of the moving masses but also environmental and sociological factors that could influence the effectiveness of the countermeasures.

    Mitigation of landslide effects is indeed rather complex because of the large extension of the territory and the particular geological and geomorphological setting. Moreover the necessity to maintain the natural condition of the area as prescribed by UNESCO, make this task even more difficult.

    Nowadays no in-depth study of the entire area exists, therefore an integrated and multidisciplinary investigation plan is going to be set up including geological and geomorphological investigations as well as archaeological and historical surveys. The better understanding of geomorphological evolution processes of the Quebrada de Humahuaca will bridge the gap between the necessity of preservation and the request of safety keeping of the recommendation by UNESCO.

  5. Simulation of Ground-Water Flow in the Middle Rio Grande Basin Between Cochiti and San Acacia, New Mexico

    McAda, Douglas P.; Barroll, Peggy

    2002-01-01

    This report describes a three-dimensional, finite difference, ground-water-flow model of the Santa Fe Group aquifer system within the Middle Rio Grande Basin between Cochiti and San Acacia, New Mexico. The aquifer system is composed of the Santa Fe Group of middle Tertiary to Quaternary age and post-Santa Fe Group valley and basin-fill deposits of Quaternary age. Population increases in the basin since the 1940's have caused dramatic increases in ground-water withdrawals from the aquifer system, resulting in large ground-water-level declines. Because the Rio Grande is hydraulically connected to the aquifer system, these ground-water withdrawals have also decreased flow in the Rio Grande. Concern about water resources in the basin led to the development of a research plan for the basin focused on the hydrologic interaction of ground water and surface water (McAda, D.P., 1996, Plan of study to quantify the hydrologic relation between the Rio Grande and the Santa Fe Group aquifer system near Albuquerque, central New Mexico: U.S. Geological Survey Water-Resources Investigations Report 96-4006, 58 p.). A multiyear research effort followed, funded and conducted by the U.S. Geological Survey and other agencies (Bartolino, J.R., and Cole, J.C., 2002, Ground-water resources of the Middle Rio Grande Basin, New Mexico: U.S. Geological Survey Circular 1222, 132 p.). The modeling work described in this report incorporates the results of much of this work and is the culmination of this multiyear study. The purpose of the model is (1) to integrate the components of the ground-water-flow system, including the hydrologic interaction between the surface-water systems in the basin, to better understand the geohydrology of the basin and (2) to provide a tool to help water managers plan for and administer the use of basin water resources. The aquifer system is represented by nine model layers extending from the water table to the pre-Santa Fe Group basement rocks, as much as 9,000 feet

    Full Text Available Prematurity is a leading cause of neonatal mortality and a global health problem that affects high, middle and low-income countries. Several factors may increase the risk of preterm birth. In this article, we test the hypothesis that different risk factors determine preterm birth in different income groups by investigating whether risk factors for preterm deliveries in the 2004 Pelotas (Rio Grande do Sul State, Brazil birth cohort vary among those groups. A total of 4,142 women were included in the analysis. Preterm births were equally common among women who had spontaneous vaginal deliveries as for those with induced or operative births. In the multivariate analysis the factors that remained significantly associated with preterm birth were black skin color, low education, poverty, young maternal age, primiparity, previous preterm birth, inadequacy of prenatal care and reported hypertension. In the analyses repeated after stratification by family income terciles, there was no evidence of effect modification by income and no clear difference between the socioeconomic groups. No association between cesarean section and preterm delivery was found. Further studies are required to understand the causes of the epidemic of preterm births in Brazil.A prematuridade é uma grande causa de morte neonatal e um problema de saúde global, afetando países de alta, média e baixa renda.

    International Nuclear Information System (INIS)

    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)

Como o setor agrícola deste estado emprega 20% do total da mão de obra ocupada, especial ênfase é dada ao mesmo. A base de dados é o Censo Demográfico de 2000 do IBGE. A análise estatística dos dados é realizada através do modelo Logit. Verificou-se que são limitadas as possibilidades de o setor agrícola, enquanto gerador do produto primário, aumentar a probabilidade dos trabalhadores de um município de auferirem maiores rendimentos do trabalho. Para maiores rendimentos é indispensável que o município agregue outros setores como, por exemplo, os que são responsáveis pela industrialização, armazenagem e transporte do produto. Aliada à esta agregação de setores, a qualificação do trabalhador para poder assumir as novas funções é importante, contribuindo para maiores rendimentos do trabalho.The article analyzes the effects of economic sectors and educational level of workers on their probability to earn higher wages, at the county level in the state of Rio Grande do Sul. Special emphasis is given to the agricultural sector, since it employs 20% of the total labor force occupied in the state. The IBGE Demographic Census of 2000 is the basis for the data. Logit is the statistical model used for the analysis. One of the conclusions of the analysis is that the possibility of the agricultural sector, in a county, to generate higher wages is limited, as long as it remains solely a producer of the primary product. In order to generate higher wages, it is necessary that the county aggregates other sectors, as for example, industrialization, storage and transportation. Besides, the qualification of the worker is also important, so he can assume new job opportunities in the aggregated sectors, which contributes

    Rio Grande do Sul showed in the last five years a significant increase in the population coverage provided by the Family Health Strategy (FHS. The changes in the organization of Primary Care proposed by the FHS already demonstrated in the great urban centers improvement in the access and other attributes of Primary Care services, as demonstrated in studies that evaluated indicators of child health when comparing the FHS with the traditional Primary Care services. This study sought analyzing the association between the population coverage of the FHS and the coverage of citopathological exams of the uterine colon among women between 25 and 59 years of age in cities of Rio Grande do Sul. This is an ecological study that used the base of secondary data of the DATASUS originating from SISPACTO over the period January to December 2006. One of the indicators of the health pact was chosen for evaluating the actions directed to women’s health – the number of cervicovaginal citopathological exams performed in the population of interest. The data were stratified into 6 groups according to the population coverage in the cities (without FHS, up to 20%, from 20% to 40%, from 40% to 60%, from 60% to 80% and more than 80% of coverage. For evaluating the influence of the population size, cities with less than 10 thousand inhabitants were compared with the others. The analysis was performed using the software SPSS v13.0 for variance analysis and post hoc test (Turkey for comparison between the coverage groups and T test for comparison of means according to the population size. As a result, one group of greater coverage showed a statistically significant difference from the group with less than 60% of coverage (p<0,05.

    Sanford, Ward E.; Plummer, L. Niel; McAda, Douglas P.; Bexfield, Laura M.; Anderholm, Scott K.

    The calibration of a groundwater model with the aid of hydrochemical data has demonstrated that low recharge rates in the Middle Rio Grande Basin may be responsible for a groundwater trough in the center of the basin and for a substantial amount of Rio Grande water in the regional flow system. Earlier models of the basin had difficulty reproducing these features without any hydrochemical data to constrain the rates and distribution of recharge. The objective of this study was to use the large quantity of available hydrochemical data to help calibrate the model parameters, including the recharge rates. The model was constructed using the US Geological Survey's software MODFLOW, MODPATH, and UCODE, and calibrated using 14C activities and the positions of certain flow zones defined by the hydrochemical data. Parameter estimation was performed using a combination of nonlinear regression techniques and a manual search for the minimum difference between field and simulated observations. The calibrated recharge values were substantially smaller than those used in previous models. Results from a 30,000-year transient simulation suggest that recharge was at a maximum about 20,000 years ago and at a minimum about 10,000 years ago. Le calibrage d'un modèle hydrogéologique avec l'aide de données hydrochimiques a démontré que la recharge relativement faible dans le Grand Bassin du Middle Rio est vraisemblablement responsable d'une dépression des eaux souterraines dans le centre du bassin et de la présence d'une quantité substantielle d'eau du Rio Grande dans l'aquifère du Groupe de Santa Fe.

METODOLOGIA: Foi realizado um estudo transversal de base populacional no município de Rio Grande (RS, constando de uma amostra de 1.044 indivíduos, de ambos sexos, com idade entre 12 e 75 anos. Definiu-se dependência de álcool pelo questionário CAGE, e o abuso de álcool foi caracterizado pelo consumo de 30 ou mais gramas por dia para homens e 24 ou mais gramas por dia para mulheres. Para controlar o efeito de fatores de confusão, procedeu-se a uma análise multivariada por regressão logística. RESULTADOS: 5,5% dos indivíduos abusavam de álcool, dos quais 2,5% eram dependentes. Após controle por possíveis fatores de confusão, identificou-se uma associação significativa entre alcoolismo e as seguintes variáveis: sexo masculino (razão de chances - RC = 6,28, tabagismo (RC = 5,42 e classe social E (RC = 5,37. CONCLUSÃO: Os resultados identificaram as dificuldades de se realizar um estudo de base populacional sobre alcoolismo e revelaram que homens que fumam e são de classe social mais baixa têm uma chance maior de apresentar problemas vinculados ao álcool. A prevalência de abuso de álcool em Rio Grande foi de 5,5%, e de dependência, 2,5%.INTRODUCCÍON:El consumo de alcohol es un problema de salud pública muy relevante.

    Full Text Available O artigo apresenta os resultados de uma pesquisa sobre a sustentabilidade dos agricultores extrativistas da região da Encosta Atlântica do Rio Grande do Sul. O extrativismo em questão é de uma espécie conhecida popularmente como samambaia-preta [Rumohra adiantiformis (G.Forest. Ching]. Estima-se que 3 mil famílias da região têm nesta atividade, não-regulamentada por lei, sua principal fonte de renda. O grau de sustentabilidade dos agricultores foi estimado através da adoção de informações relativas às dimensões ambiental, social e econômica e aos critérios de produtividade, estabilidade, equidade, resiliência e autonomia. A análise focou-se na comparação entre os Índices Relativos das Dimensões (IRD, dos Critérios (IRC e de Sustentabilidade (IRS de cada tipo de sistema de produção. Os resultados apontaram para a existência de 4 tipos de sistemas de produção, sendo 3 deles abrangidos nessa pesquisa. Os sistemas de produção dos tipos 1 e 2 se caracterizam pela baixa disponibilidade de meios de produção e por uma grande dependência de rendas não-agrícolas e do extrativismo. O sistema de produção do tipo 3 é caracterizado pela prática de agricultura de subsistência e de atividades agrícolas de cunho comercial, sem depender muito da prática extrativista. Os indicadores de sustentabilidade apontaram que o sistema de produção do tipo 3 se mostrou o mais sustentável, seguido pelo tipo 2 e, por último, pelo tipo 1.This article reports the results of a research about the sustainability of extractive farmers in the Atlantic slopes of Rio Grande do Sul.

Geralmente estes produtos não são fabricados em acordo com as boas normas de fabricação e podem constituir perigo à saúde do consumidor. Objetivou-se, com o presente trabalho, verificar a qualidade bacteriológica de queijos artesanais comercializados em estradas litorâneas por meio da contagem de coliformes e pesquisa de Listeria spp. e Brucella spp. Foram analisados 80 queijos, sendo 62 do tipo Colonial, dez do tipo Provolone, seis do tipo Ricota e dois do tipo Caccio Cavallo. No momento da coleta, 71% das amostras não estavam sob refrigeração. Todas as amostras apresentaram contagens de coliformes totais e, destas, 62 foram testadas para a presença de coliformes fecais. Um total de 84% das amostras apresentou contagens de coliformes fecais acima de 2,73- 3,7 log.UFC g- 1 (de 500 a 5000UFC mL-1, previsto como limite máximo a ser encontrado em queijos. Dos 29 estabelecimentos, 27 tinham produtos fora destes limites. Das 80 amostras, 16% continham Listeria spp., sendo 3,7% identificadas como Listeria monocytogenes. As estações do ano influenciaram no isolamento de Listeria spp., sendo a primavera considerada a estação do ano com maior número de isolados. Brucella spp. não foram isoladas nas 80 amostras de queijos analisadas. A alta freqüência de coliformes fecais e a presença de L. monocytogenes revelam que o consumo destes queijos constitui perigo de infecção à população em geral e especialmente àquelas pessoas imunocomprometidas.The consumption of homemade cheese, which is sold in little shops along the road, is very common in the state of Rio Grande do Sul, Brazil.

    Red rice is one of the most important weeds of cultivated rice in Brazil. On the other hand, red rice constitutes a collection of genes lost during the cultivated rice domestication process and has a fundamental importance for recovery of promising genic constitutions. This study had the objective to analyze the genetic variability of a colletion of red rice (Oryza sativa L. ecotypes from Rio Grande do Sul State, Brazil, through isoenzimatic and microsatellite markers. Thirty four accesses from the Seed and Biotechnology Laboratory germplasm bank, at Federal University of Pelotas, were analyzed using six isoenzimatic systems and nineteen microsatellite markers. Twenty-three biochemical and 54 molecular alleles were identified and used to estimate the polymorphism (PIC and genetic similarity indexes. The analyzed red rice population presents large genetic variability, evidencing the potentiality to map characteristics of interest to seed physiology. Biochemical markers of the isoenzime type and molecular markers of the microsatellite type are efficient to estimate the genetic variability in red rice ecotypes.

Com o objetivo de verificar essas diferenças na disponibilidade de P para o arroz em solos oriundos de diferentes materiais de origem, conduziu-se um experimento fatorial, delineado em blocos ao acaso, em que cinco solos foram submetidos à ausência ou presença de superfosfato triplo. Os solos derivados de sedimentos de arenito e granito (Planossolos apresentaram redução mais rápida do Fe com liberação do P adsorvido, quando comparados aos solos derivados de sedimento de basalto. Os Planossolos apresentaram maior quantidade de P acumulado no arroz que o Vertissolo e Chernossolo, sem ou com a adição de superfosfato triplo. A adição de superfosfato triplo resultou em maior quantidade de P acumulado na planta para todos os solos.Soils used for production of flooded rice in the state of Rio Grande do Sul are originated from different parent materials, resulting in different characteristics that affect P availability for the crop. The aim of this paper was to verify the differences in P availability for rice in soils originated from different parent materials. The experiment was carried out in a complete randomized block design, where five soils were exposed to absence or presence of triple superphosphate. In the soils derived from sandstone and granite sediment a faster Fe reduction and release of adsorbed P was observed than in soils originated from basalt. The amount of accumulated P in rice was higher in the Planosol than the Vertisol and Mollisol, with and without triple superphosphate application. Triple superphosphate fertilization resulted in greater amounts of P accumulated in all soils.

    Full Text Available Desenvolveu-se neste estudo uma comparação entre larvicidas químicos e biológicos usados em programas de controle de mosquitos no Rio Grande do Sul. Em bioensaios de laboratório contra Culex quinquefasciatus constatou-se que as formulações biológicas líquidas Vectobac 12 AS e Teknar 3000 (Bacillus thuringiensis israelensis, ABG 6262 líquido e em pó (B. sphaericus 2362, foram altamente eficazes. Também as formulações experimentais de B. thuringiensis israelensis produzidas em laboratórios brasileiros foram consideradas adequadas. Entre as formulações químicas, os compostos piretróides Pirisa e K-Othrine produziram resultados melhores do que os organo-fosforados Lebaycid e Abate. Estes últimos produziram respostas dez vezes mais fracas do que o previsto em outros estudos. Em condições de campo, a dose de 1250 mg/m² para as formulações biológicas foi considerada adequada para a rotina das aplicações, porque permite superar as influências físicas do meio sobre os resultados. Somente as formulações de B. sphaericus produziram interrupções nas reinfestações dos focos de culicídeos observados. Períodos de até 39 semanas sem reinfestações foram observados em focos naturais e de um mês sem sobrevivência foi observado em tanques, onde procedia-se a reinfestação artificial. Este estudo sugere que as alternativas biológicas devem ser consideradas em programas de controle de mosquitos. Elas podem superar os problemas de resistência e eliminação, bem como da ausência de efeito residual nas aplicações de larvicidas.A comparison between chemical and biological larvicides in routine operations against mosquitoes in Rio Grande do Sul State was carried out in this study.

    system, inside the greenhouse, in two regions with different ecoclimatic conditions, in Eldorado do Sul (Depressão Central and Caxias do Sul (Serra do Nordeste, in Rio Grande do Sul State. Four strawberry cultivars were tested: Aromas, Camarosa, Oso Grande and Tudla. The planting was in May 2005, and the seedlings were placed in bags containing substrate composed of 50% of peat and 50% charred rice hulls. The fertilizer was supplied by fertirrigation. Fruits were harvested when 70% of them presented red color up to fully mature. The results showed that the cultivation of strawberries in this system led to lower yield per plant than in a traditional system, but provides better use of internal greenhouse, with positive consequences in yield per area, due to the high density of plants and the facility to manage the crop. The highest productivity was obtained in Caxias do Sul (235.8 g plant-1 compared to Eldorado do Sul (196.4 g plant-1 without interaction between locations and cultivars. In Caxias do Sul, the cultivars Aromas, Oso Grande and Camarosa presented highest yield when compared to Tudla, but there was no difference in Eldorado do Sul.

    Social and ecological scientists emphasize that effective natural resource management depends in part on understanding the dynamic relationship between the physical and non-physical process associated with resource consumption. In this case, the physical processes include hydrological, climatological and ecological dynamics, and the non-physical process include social, economic and cultural dynamics among humans who do the resource consumption. This project represents a case study aimed at modeling coupled social and physical processes in a single decision support system. In central New Mexico, individual land use decisions over the past five decades have resulted in the gradual transformation of the Middle Rio Grande Valley from a primarily rural agricultural landscape to a largely urban one. In the arid southwestern U.S., the aggregate impact of individual decisions about land use is uniquely important to understand, because scarce hydrological resources will likely limit the viability of resulting growth and development trajectories. This decision support tool is intended to help planners in the area look forward in their efforts to create a collectively defined 'desired' social landscape in the Middle Rio Grande. Our research question explored the ways in which socio-cultural values impact decisions regarding that landscape and associated land use. Because of the constraints hydrological resources place on land use, we first assumed that water use, as embodied in water rights, was a reasonable surrogate for land use. We thought that modeling the movement of water rights over time and across water source types (surface and ground) would provide planners with insight into the possibilities for certain types of decisions regarding social landscapes, and the impact those same decisions would have on those landscapes. We found that water rights transfer data in New Mexico is too incomplete and inaccurate to use as the basis for the model. Furthermore

    The present study chemically characterized sediment samples from the Billings reservoir, Rio Grande tributary, in the Metropolitan region of Sao Paulo, by determining metal concentration and other elements of interest. The chosen chemical parameters for this characterization were Aluminum, Arsenic, Barium, Cadmium, Copper, Chromium, Iron, Lead, Manganese, Mercury, Nickel, Selenium and Zinco. These parameters are also used in the water quality index, with the exception of Selenium. The concentrations were determined through different analytical techniques such as atomic absorption spectrometry (FAAS, GFAAS and CVAAS), optical emission spectrometry (ICP OES) and neutron activation analysis. These analytical methodologies were assessed for precision, accuracy and detection and/or quantification limits for the sediment elements in question. Advantages and disadvantages of each technique for each element and its concentration were also discussed. From these assessments the most adequate technique was selected for the routine analysis of sediment samples for each element concentration determination. This assessment verified also that digestion in a closed microwave system with nitric acid is efficient for the evaluation of extracted metals of environmental interest. The analytical techniques chosen were equally efficient for metals determination. In the case of Cd and Pb, the FAAS technique was selected due to better results than ICP OES, as it does not present matrix interference. The concentration values obtained for metals As, Cd, Cu, Cr, Hg, Ni, Pb and Zn in the sediment samples were compared to Canadian Council of Minister of the Environment (CCME) TEL and PEL values.

    Full Text Available The benthic fauna has an important role in the trophic chain of limnic environments, serving as food for fishes and crustaceans. This work aimed to identify and compare, quantitative and qualitatively, the macrobenthic communities from two watercourses in Rio Grande do Sul State. Samplings were done with a Surber sampler, monthly, from September 1999 to August 2000, in one of the creeks forming Tainhas River(29º15'30,2"S, 50º13'12,5"W, around São Francisco de Paula city and in Mineiro Creek (29º30'0,2"S, 50º46'50"W, around Taquara city. At each sampling point, physical and chemical variables of the waters were registered. In the laboratory, the samples were sorted out and the animals identified and quantified. Dissolved oxigen, pH and stream speed were very similar for both environments, whilst conductivity had extreme values. Insects, crustaceans, acari and molluscs dominated in the samples. Abundance, richness and diversity indexes in Tainhas subsidiary had relatively higher average values than Mineiro Creek. Similarity matrix groupings between sampling units indicate three groups. Our research revealed important characteristics of the ecology and distribution of benthic invertebrates, information that can subsidise future environmental monitoring in the region of São Francisco de Paula and Taquara.

The statistical interpretation included Test of Normality, Coefficient of Variation, Correlation and Regression Analysis, Cluster Analysis, Discriminant Analysis and Principal Component Analysis. RESULTS: Eighteen lakes were described and five of them are presented by aerial photo and bathymetric map. They represent the proposed morphological lake types. The calculation of the coefficient of variation revealed larger amplitudes of parameters related to lake size than to depth. The application and interpretation of cluster analysis, confirmed by discriminant analysis, distinguished those lakes in five morphological groups, which differ mainly by size and subsequently by depth. The Principal Component Analysis identified the first component with positively charged variables of size and negatively charged relative depth, and a second component with positive charge of maximum and average depths. CONCLUSIONS: The low relative depths and the exposure to constant northeastern winds reduce the transparency of the lakes. Consequently, they are light limited by suspension of inorganic and organic matter. A property that limits the application of trophic state indices. The high dynamic of the water bodies produces an oxygenated sediment surface that facilitates the settlement by aerobic organisms all over the bottom area. The shallowness

    Full Text Available Este trabalho teve por objetivo estudar a possível ocorrência de heterocariose por meio do pareamento de fungos provenientes de diferentes espécies de formigas cortadeiras coletados em diferentes regiões do Estado do Rio Grande do Sul, utilizando a técnica AFLP. Dez grupos de pareamentos foram realizados, sendo que em dois não ocorreu a fusão das colônias. Após ocorrerem os pareamentos, foram coletados discos de micélio da área de intersecção das colônias e das áreas extremas de pareamento, para a realização da extração do DNA e padronização. Para as reações de PCR, utilizaram-se 21 combinações de primers AFLP, dos quais foram selecionados três que apresentaram maior polimorfismo e consistência. Os dados moleculares foram transformados em matriz binária e analisados pelo programa estatístico NTSYS v. 2.1. As três combinações de primers utilizadas geraram 245 bandas polimórficas. A similaridade média dos genótipos variou de 0,03 a 0,18 em todos os pareamentos. A grande distância genética encontrada entre os organismos possivelmente ocorreu por três fatores: a possível ocorrência de heterocariose entre os fungos, a utilização de fungos oriundos de diferentes espécies de formigas e de diferentes regiões. O trabalho sugere que a heterocariose pode representar um importante papel no ciclo de vida deste fungo, uma vez que sua multiplicação é clonal e há ausência de frutificação.This research work had as objective to study the possible heterokaryosis occurrence through the fusion of mushrooms originating from nests of different species of cutter ants collected in different areas of the State of Rio Grande do Sul, using the AFLP technique. Ten fusion groups were accomplished, from which two did not perform a colony coalition. After the fusion occurred, disks of mycelium of the colonies intersection area and fusion external areas were collected, the extraction of DNA and standardization was performed

A história da sociedade gaúcha não explica o nascedouro de movimentos sociais e de inovações na gestão pública nos anos 1980 e 1990, necessitando, portanto, de uma análise mais profunda para entender a forte participação popular. Este artigo resume em seis secções os resultados da observação participante entre 1996 e 2002, bem como a revisão bibliográfica realizada entre 2002 e 2005. Na primeira secção é apresentada a necessidade de entender os processos de democratização de forma diferenciada para sistemas políticos de grande dimensão, e na segunda secção, a bibliografia que apóia esta perspectiva. A terceira secção resume o processo formativo da sociedade gaúcha através da análise da criação de redes de núcleos urbanos, fornecendo a base para a quarta secção sobre as origens da sociedade civil. A quinta secção analisa os atores que influíram de modo ativo na promoção da participação popular nos anos 1970 e 1980, concluindo na sexta secção sobre o papel fundamental exercido pela utopia da Igreja Católica.This article analyzes the elements that allowed the transition of a regional militaristic society to one of the highest quality democracies in Latin America.

    Full Text Available A infestação por carrapatos em bovinos é responsável por perdas econômicas significativas à indústria animal em várias regiões brasileiras, incluindo o Rio Grande do Sul. As perdas se devem ao stress, a perdas de peso e a injúrias na pele, bem como aos custos com tratamentos. O uso indiscriminado de carrapaticidas tem contribuído para o aparecimento da resistência genética dos ixodídeos a várias drogas, representando um sério problema no controle de carrapatos. O objetivo deste trabalho foi avaliar a susceptibilidade das diferentes espécies de campo de Rhipicephalus (Boophilus microplus aos acaricidas usados nos controles dos parasitas. Para tanto, amostras de carrapato foram coletadas em 42 propriedades localizadas em diferentes municípios do Estado para a realização do teste de imersão de teleóginas (biocarrapaticidograma. A associação do amitraz e do clorpirifós resultou na droga que apresentou maior eficácia em 100% das propriedades testadas (11/11.

A cipermetrina foi eficiente em 20,7% (6/29 e o amitraz, um dos produtos mais utilizados nas propriedades, foi eficiente em 14,2% (6/42 das propriedades. Os resultados demonstraram que muitas drogas utilizadas no controle do R. (B. microplus no Estado apresentaram baixa eficácia, conforme os resultados dos testes in vitro. A baixa eficácia das drogas provavelmente se deve à resistência genética desenvolvida pelos parasitas devido ao uso indiscriminado dos carrapaticidas a campo.Infestation by ticks is responsible for significant economic losses to the cattle industry in several regions, including Rio Grande do Sul (RS state.

    Full Text Available OBJETIVO: Analisar os aspectos epidemiológicos das fissuras orais em crianças nascidas entre 2000 e 2005 no Estado do Rio Grande do Norte, Brasil. MÉTODOS: Realizou-se um estudo transversal com dados obtidos do Sistema de Informações sobre Nascidos Vivos (Sinasc disponibilizados pela Secretaria de Vigilância em Saúde do Ministério da Saúde. Descreveu-se a faixa etária da mãe, o tipo de fissura, o tipo de parto, o peso ao nascer, o sexo, a etnia da criança e as regionais de saúde. RESULTADOS: Nesse período, o número de nascidos vivos no Estado foi de 318.667, dos quais 155 possuíam algum tipo de fissura de lábio e/ou palato, representando uma prevalência de 0,49 casos/1.000 nascidos vivos. Ao se avaliar a prevalência nas oito regionais de saúde, Grande Natal (0,51, João Câmara (0,81 e Santa Cruz (0,67 ficaram um pouco acima da média do Estado. Entretanto, existiram municípios com valores discrepantes dessa frequência, como o de Maxaranguape, com uma prevalência de 3,52 casos/1.000 nascidos vivos e Serra do Mel, com 2,52 casos/1.000 nascidos vivos. O tipo mais frequente foi fenda labial com envolvimento palatino, e o sexo masculino foi o mais atingido. CONCLUSÕES: A prevalência das fissuras orofaciais foi baixa para o Estado. Destaca-se que alguns municípios merecem atenção devido à alta prevalência da malformação, havendo necessidade de estudos para compreender os potenciais riscos teratogênicos aos quais a mulher grávida pode estar exposta e que propiciam anomalias congênitas, tais como as fissuras labiopalatais.OBJETIVO: Analizar los aspectos epidemiológicos de las fisuras orales en niños nacidos entre 2000 y 2005 en el estado de Rio Grande do Norte, Brasil.

    Full Text Available The authors present a quantitative and qualitative study on homicides among teenagers in Porto Alegre, Rio Grande do Sul State, Brazil, based on a historical series during the 1990s and the life and death histories in this group, with a special focus on 1997. In that year there were 68 homicides in which the victims were from 10 to 19 years old. Of the 68, 62 were males and only 6 females, or a ratio of 10:1, showing that young males are more vulnerable and susceptible to being murdered. The data indicate that cause of death is influenced by gender culture and that homicides are based on power and status symbols characterizing a kind of virility. This expression of virility in the shaping of violence also appears in the domination of the female body observed in homicides with young women as the victims. The life and death histories of these teenagers highlight the pertinence of the gender-based analysis as a theoretical-analytical category, in addition to analyses considering socioeconomic aspects and social inequity.

    Sex education has been included in the National Curriculum of the Brazilian Ministry of Education since 1996 as a cross-cutting theme that should be linked to the contents of each school subject in primary and high schools. This paper presents a study of the implementation of this policy in the primary schools of Novo Hamburgo, Rio Grande do Sul, Brazil, based on interviews between January 2011 and April 2012 with 82 teachers working in those schools. We found that sex education was not being taught as a cross-cutting theme in any of the schools, and that any lessons were mostly dominated by a biomedical discourse focusing primarily on the reproductive organs, fertility, pregnancy, and contraception. Sexual health and relationships and non-heterosexual sex and relationships were being neglected. Sex education was also considered a possible means of correcting or controlling sexual identities and behaviours deemed abnormal or immoral. We recommend far more discussion of how to implement the National Curriculum recommendations. We call for education courses to provide theoretical and methodological training on sex education for teachers, and recommend that the boards of educational institutions take up sex education as a priority subject. Lastly, we suggest that each school studies local sexuality-related problems and based on the findings, each teacher presents a pedagogical proposal of how to integrate sex education into the subjects they teach.

    Full Text Available This study was conducted with the objective of quantifying the production of wood in the Area of the Fourth Colony of Italian Immigration in Rio Grande do Sul. Firstly, using a questionnaire, a census of the consuming companies of wood in that area was made, investigating mainly the amount, type, origin of the consumed raw material, and the amount, type and end use of wood products. As principal results, it was verified that such area presents 77 consuming companies and wood processing units. These were classified into micro and small companies, with familiar features and capital, and low industrialization. In the visits made to the industries, it was evident that many technological aspects are not known or are neglected, thus causing loss of the raw material and/or in low quality of the final products. A great amount of raw material (96,8% of the boards and 98,9% of the timber comes from other areas of the State or the country. In the same way the main products are sold abroad (wood frames 86,3%, panelings 99,7%, sawed wood 53%.

    Behavioral and mental health problems are not always considered in temporary medical clinics nor are instruments readily available to provide medical practitioners in these settings with information relevant to mental health conditions. This study provided preliminary data on the utility of the Mini Mental Screen in temporary military medical clinics in the Texas Rio Grande Valley. This instrument was administered to individuals who may have behavioral or mental health problems. In a sample of mostly Hispanic patients (N = 75) seen at a temporary medical clinic, 12% were at significant risk of mental health problems, with an additional 9% at moderate risk using published cut-off scores for the risk of such problems. The results for each patient were provided to a medical practitioner who further evaluated the risk, treated the problem, or made a referral. When asked, three of four medical practitioners found that screening data was helpful in their work with patients. One practitioner was concerned that the screening instrument might have too high a false positive rate to be useful. Cultural issues of openness about mental health and behavioral problems need to be considered in such settings. PMID:21957754

    Full Text Available This article is part of the research study performed in the South Region of Brazil, in a center in a network connected to the Observatory of Education. The study aimed to analyze, in rural schools, the aspects associated with the low Basic Education Development Index (IDEB - Índice de Desenvolvimento da Educação Básica. The main focus was the official data and the ten public schools with the lowest IDEB. What we socialized is the study performed by the center in the State of Rio Grande do Sul (RS. The theoretical-methodological approach is connected to the Dialectic Historical Materialism, with an Analysis of Content. The problems related to low IDEB are spelled out and analyzed by the rural schools and aspects to be considered in the evaluation of education by the IDEB are indicated. It was concluded that, although the schools do not take a position contrary to the IDEB, they point out the need for democratization.

    Full Text Available AIM: the aim of this study was to determine the ecological valence of benthic macroinvertebrates at different pollution levels in highland rivers and streams of Rio Grande do Sul; METHODS: the dataset proceeds from samplings performed between 2002-2011 in 35 lotic ecosystems. The Chemical Index was used to determine pollution levels. Indices of richness and Shannon diversity were applied to characterize the structure of benthic communities. The descriptors used to determine taxa's ecological valence were selected according to Coefficient of Variation and regression analyses. Groups of tolerance were identified using Interquartile range and cluster analysis; RESULTS: Conductivity and Chemical Index were the descriptors best related with diversity of benthic macroinvertebrate community. These metrics were used to determine the tolerance range of 38 taxa. Interquartile range and cluster analysis revealed three groups of taxa, according to their occurrence in different levels of pollution: taxa with narrow amplitudes, present at sites with very low or very high load of organic enrichment; taxa with moderate amplitude, found until moderately polluted sites; and taxa with occurrence in widespread environmental conditions. The results, when compared to other studies in Brazil, showed differences in some taxa's tolerance. This observation indicates the need to assess the bioindication potential of these taxa in genus and species level; CONCLUSION: the present study contributes to increase knowledge about the bioindicator potential of benthic macroinvertebrates. Therefore, the study supports an advanced biomonitoring of ecological quality in mountain streams of southern Brazil.

    Full Text Available Toxoplasmosis is caused by Toxoplasma gondii, which is the main causative agent of abortion in small ruminants. Goats are among the animals that are most susceptible to this protozoon, and the disease that it causes leads to significant economic losses and has implications for public health, since presence of the parasite in products of goat origin is one of the main sources of human infection. Because of the significant economic impact, there is an urgent need to study the prevalence of T. gondii infection among goats in Sertão do Cabugi, which is the largest goat-producing region in Rio Grande do Norte. In the present study, the ELISA assay was used to test 244 serum samples from nine farms, located in four different municipalities in the Sertão do Cabugi region, which is an important goat-rearing region. The results showed that the prevalence of anti-T. gondii antibodies was 47.1% and that there was a significant association between positivity and the variables of age (≥ 34 months, location (Lajes, Angicos and Afonso Bezerra and farm (all the farms. The avidity test was applied to all the 115 ELISA-positive samples to distinguish between acute and chronic infection. One hundred and three samples (89.6% displayed high-avidity antibodies, thus indicating that most of the animals presented chronic infection, with a consequent great impact on the development of the goat production system and a risk to human health.

  19. Benthic Foraminifera and Bacterial Activity as a Proxy for Environmental Characterization in Potengi Estuary, Rio Grande do Norte, Brazil

    2010-01-01

    Full Text Available The aim of this study was to identify possible zonation patterns and assess the environmental impact on the Potengi River Estuary, Rio Grande do Norte State, through the distribution of benthic foraminifera associated to bacterial activity and abiotic parameters. Six sediment samples were collected from locations that presented clear signs of pollution. The environment was predominantly anaerobic and fermentation occurred at all sites. Forty-two species of foraminifera were identified. The dominant species were Ammonia tepida and Arenoparrella mexicana, which are known to be opportunistic, and able to adapt to rapidly changing conditions. CCA analyses showed that salinity and organic matter, followed by bacterial carbon, were more strongly linked to organism distribution in the Potengi River Estuary. Dissolved oxygen concentration, temperature and total organic matter were higher at the estuary mouth than at the other sites, creating favorable conditions for foraminiferal growth and allowing the faunistic succession on the upper estuary. As foraminifera assemblages when associated to environmental parameters can be used as efficient proxies for environmental diagnosis, these results suggest that the Potengi Estuary is under great stress from the surrounding urban development.

    Full Text Available En este artículo se analizan las primeras décadas de la transformación del paisaje en el noroeste de Rio Grande do Sul, en el siglo XX, después de la entrada de inmigrantes europeos y sus descendientes. Básicamente, la transformación del paisaje en el área de estudio tuvo dos momentos diferentes, con características diferentes, sobre todo en la intensidad de las medidas de intervención en el espacio. La primera, en las primeras décadas, en las que los inmigrantes utilizan básicamente herramientas para combatir incendios y de la mano (sierras, hachas, azadas, etc para la tala del bosque y la producción agrícola, y la segunda una después de la segunda mitad del siglo, con intensificación de la intervención de la modernización de la agricultura. Esto, ya que sólo profundiza los desequilibrios ambientales que ya habían ocurrido en menor medida en el tiempo anterior, pero preocupante, sobre todo en la degradación de los suelos y el agua y el ataque “plagas” a la producción agrícola, discutidos en este artículo.

  1. Monitoring the domiciliary and peridomiciliary invasion process of Triatoma rubrovaria in the State of Rio Grande do Sul, Brazil

    Full Text Available The presence of Triatoma rubrovaria in Brazil has only been confirmed in the States of Paraná and Rio Grande do Sul (RS, where it is found naturally infected with Trypanosoma cruzi. In the wild environment it occurs in rocky habitats and has an eclectic diet, feeding from cockroaches, reptiles and mammals. Data from the Chagas Disease Control Program obtained by the Fundação Nacional de Saúde, between 1975 and 1997, indicate a growing domiciliary and peridomiciliary invasion of T. rubrovaria in RS, where it has become the most frequently Triatominae species captured in this state since the control of Triatoma infestans. In order to monitor this process, we analyzed collection data derived from 22 years of control campaigns against T. infestans. Collection data for triatomines from domestic habitats show an inverse relationship, with high numbers of T. infestans and low numbers of T. rubrovaria during 1976-1987, compared to the following ten years, 1986-1997, when the number of T. infestans dropped drastically and that of T. rubrovaria increased. There are no consistent indications of intradomiciliary colonization by T. rubrovaria, since only low numbers of nymphs have been captured in the intradomiciliary ecotopes. Nevertheless, this species appears to have preadaptive characteristics for anthropic ecotopes, and should be kept under constant epidemiological surveillance.

    Full Text Available Technology development and globalization caused worldwide changes in companies, requiring a new profile oforganizational leaders. In this context, personality has become a decisive factor in obtaining professionalsuccess. Quality of life (QOL is a broad research topic in management studies. By employing the Big FiveFactors model, this explanatory research sought to investigate which personality characteristics of managersinfluence their quality of life. The sample consisted of 100 managers, with 77% men and 23% women, from 27companies in Brazil’s Rio Grande do Sul state. The study applied a Factorial Personality Test Battery, the briefversion of the World Health Organization Quality of Life test (WHOQOL-BREF, and a socio demographicquestionnaire. Main results indicated that there is a negative correlation between QOL and Neuroticism andpositive associations between QOL and Extroversion, indicating that being more communicative, active, andgregarious and having less emotional instability are characteristics that positively affect managers’ health.Furthermore, Neuroticism showed to be a predictor of QOL, demonstrating that better adjusted and moreemotionally stable managers have greater wellbeing. These results may help the planning of future interventionsaimed at promoting these individuals’ health.

    Full Text Available The study aimed to evaluate the accumulation of P fractions in a vineyard soil profile with successive applications of phosphate fertilizers. In January 2010 an area was selected of native forest and a vineyard at age 33 with a history of phosphate fertilizer application, in Bento Gonçalves, Rio Grande do Sul state. Soil samples were collected from 0-5, 5-10 and 10-20 cm layers, prepared and submitted to chemical fractionation of P. The excessive application of phosphate fertilizers during 33 years in the vineyard soil increased the levels of organic and inorganic P until the 20 cm layer in all P fractions. The highest levels of P in the vineyard soil were found mainly in the labile fractions extracted with anion exchange resin and NaHCO3, which indicates high nutrient availability to plants, but also indicates the potential of transfer of solution from soil to surface run-off or percolated through the soil profile, which represents greater potential for contamination of surface and subsurface waters.

    Serra da Borborema, in Northeast Brazil, along the border of the states of Rio Grande do Norte and Paraiba, is known for comprising thousands of pegmatitic bodies and it is called Borborema Pegmatite Province. The pegmatites are exploited for gems and non-metallic ores and also for metallic by-products. Many of these bodies are mined for radiominerals and radioactive minerals in so-called garimpos, illegal mines, with dangerous and insalubrious working conditions. In order to locate the sources of commercial batches of columbite-tantalite (coltan) ores, exported between 2000 and 2004, were made radiometric surveys in these mines in the region of the city of Parelhas and radioactive samples collected from the batches were analyzed for uranium, thorium, niobium, and tantalum. The gamma radiation was measured in the pegmatites, also from their enclosing rocks and from the surrounding soil. The results indicate that uraninite has been mixed with coltan ores, but these minerals themselves show considerable contents of uranium and thorium. Chemical analyses indicate four distinct trends for uranium, possibly correlated with previously and already observed four structural features which control the pegmatites, and also evidencing four magmatic-metasomatic events of their emplacement. Regarding the working conditions in the mines, the sparsely presence of uranium minerals does not necessarily represent a hazard for the workers. Laboring risks are much higher than any kind of radioactive risk. (author)

    Full Text Available Species of thrips (Insecta, Thysanoptera in two strawberry production systems in Rio Grande do Sul, Brazil. Thrips are tiny insects responsible for the reduction of strawberry fruit quality. The work aimed to record and quantify the thysanopterofauna present in two strawberry production systems, low tunnel and semi-hydroponic. Leaves, flowers and fruits were collected weekly, from July 2005 to December 2006 in Caxias do Sul and Bom Princípio municipalities, RS. A total of 664 individuals were collected, representing two families, four genus and 10 species: Frankliniella occidentalis (Pergande, 1895, F. schultzei (Trybom, 1910, F. rodeos Moulton, 1933, F. simplex (Priesner, 1924, F. williamsi (Hood, 1915, F. gemina (Bagnall, 1919, Frankliniella sp., Thrips tabaci (Lindeman, 1888, Thrips tabaci (Lindeman, 1888, Caliothrips fasciatus (Pergande 1895 from Thripidae and Heterothrips sp. from Heterothripidae. Frankliniella occidentalis represented 89.7% of the samples with 95.8% of the species collected in flowers, 3.9% in fruits and 0.8% in leaves. The results show that flowers are the most important food resource for these insects on strawberry plants. Frankliniella rodeos, F. simplex, F. williamsi, C. fasciatus, and Heterothrips sp. are new records on strawberry for Brazil.

    The various soil types within the flood plains of Rio Grande in El Paso 's Lower Valley have long been utilized by local farmers. These soils are typically more conducive to farming than the more recent (Pliocene) sandy soils outside of the flood plain region. This project will explore the various properties of these soils types such as their grain size, depths, extent, and hydrological conductivity utilizing various geophysical and geochemical methods. The study site is located in El Paso 's Lower Valley and is situated in an actively farmed area. Soil maps from the Natural Resource Conservation Service (NRCS) and variations in vegetation growth will help delineate locations of soil types in the study area. The information that will be collected will produce baseline data to help track expected seasonal variations in the soil's moisture content and in the depth of the local water table. This project represents a collaboration between El Paso Community College's and the University of Texas at El Paso's Departments of Geological Sciences as a means for students majoring in Geological Sciences at El Paso Community College to gain hands on experience in researching geological issues through partnerships with their future institution and faculty.
