    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.

    Full Text Available Benthic macrofauna zonation was studied for one year (June 2004 to May 2005 with monthly sampling on Cassino Beach, Rio Grande do Sul, Brazil. Three sites (spaced 50 m apart were selected. Three transects were anchored at each site, spaced equidistantly 2 m apart. Each transect extended from the base of the primary dunes to the inner surf zone at approximately 1m in depth, with between 7 and 8 sampling levels. Monthly, with a 20 cm diameter core, one biological sample was collected per transect at each level, a total of nine samples per level. Within transects, the distance between the levels was 20 m until the upper swash zone, from which the distance was 10 m until the 1-meter isobath. Zonation proved to be variable throughout the year. Variability was mainly a reflection of the greater instability of the lower part of the beach, which comprised the lower mesolittoral zone and the inner surf zone. This was evidenced seasonally with the formation of distinct groups of fauna in accordance with the peculiarity of each season of the year. The formation of these groups was strongly influenced by fluctuations in densities stemming from recruitments and the migration of juvenile and adult infauna, as well as superimposing of the distribution of organisms as a result of rises in sea level due to storms.A zonação da macrofauna bentônica na praia do Cassino, Rio Grande do Sul, Brasil, foi estudada durante um ano (junho 2004 a maio de 2005 com base em coletas mensais.

    Full Text Available The paper discusses the role that the milk production can carry out in a development strategy for the Rio Grande do Sul State (Brazil. It was verified that an important contribution that the milk production could provide to the development it derives of its capacity of maintenance of the population in the rural zones, which enhance its effects on the local economies. These effects are generated by the high potential of aggregation of value that the dairy activity can provide in a direct, indirect and induced way. So for the milk production can play this function, however, it is necessary orientate the current policies sustained by the representatives of the agro-industrial chain that can lead more than two thirds of the producers to the exclusion in the short period. The main conclusion of the paper is that the promotion of production systems adapted to the conditions of the family production would be an indispensable condition for the construction of a development model more equitable and balanced territorially

    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.

    The basement depth in the Rio Grande Rise (RGR), South Atlantic, is estimated from combining gravity data obtained from satellite altimetry, marine surveys, bathymetry, sediment thickness and crustal thickness information. We formulate a crustal model of the region by inverse gravity modeling. The effect of the sediment layer is evaluated using the global sediment thickness model of National Oceanic and Atmospheric Administration (NOAA) and fitting the sediment compaction model to observed density values from Deep Sea Drilling Project (DSDP) reports. The Global Relief Model ETOPO1 and constraining data from seismic interpretation on crustal thickness are integrated in the inversion process. The modeled Moho depth values vary between 6 and 27 km over the area, being thicker under the RGR and also in the direction of São Paulo Plateau. The inversion for the gravity-equivalent basement topography is applied to gravity residual data, which is free from the gravity effect of sediments and from the gravity effect of the estimated Moho interface. We find several short-wavelengths structures not present in the bathymetry data. Our model shows a rift crossing the entire Rio Grande Rise deeper than previously presented in literature, with depths up to 5 km in the East Rio Grande Rise (ERGR) and deeper in the West Rio Grande Rise (WRGR), reaching 6.4 km. An interesting NS structure that goes from 34°S and extends through de São Paulo Ridge may be related to the South Atlantic Opening and could reveal an extinct spreading center.

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

    We use three years of measurements from 25 continuous GPS stations across the Rio Grande Rift in New Mexico and Colorado to estimate surface velocities, time series, baselines, and strain rates. The stations are part of the EarthScope Rio Grande Rift experiment, a collaboration between researchers at the University of Colorado at Boulder, the University of New Mexico, and Utah State University. The network includes 5 east-west station profiles transecting the rift, with the southernmost line in southern New Mexico and the northernmost line in northern Colorado. Most of the stations have shallow-drilled braced monuments installed in 2006-2007 and will remain occupied until 2010-2011 or longer. We also estimate station coordinates and velocities from the 2001 and 2008 High Accuracy Reference Network (HARN) campaigns conducted in Colorado. Initial 72-hour observations were made in the summer of 2001 and were repeated in the summer of 2008. Data from regional Plate Boundary Observatory (PBO) GPS stations are included in the processing to increase station density and extend profiles further to the east and west of the Rio Grande Rift. We use GAMIT/GLOBK to process regional sub-networks that share several common sites well determined in the Stable North America Reference Frame (SNARF). These common sites are used as a tie between the sub-networks and SNARF. Our time series from the first three years of the experiment show excellent monument stability. We have solved for baseline distance as a function of time across each of these lines. Despite what might be expected for a rigid Colorado Plateau moving away from rigid North America about a pole near Colorado, we find no evidence of an increase in Rio Grande Rift opening to the south. Our results suggest that steady-state extension across the rift from northern Colorado to southern New Mexico has an upper bound less than ~1 mm/yr with strain rates less than ~20 nanostrain/yr, although these results are still preliminary

    1993-03-01

    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.

    Full Text Available Objectives: To analyze the data in the literature, which show a high incidence of mandibular fractures. The aim of this research was to elucidate the context in which these fractures occur among patients attended at the first aid center of “Pronto Socorro Municipal de Pelotas”, Rio Grande do Sul, Brazil. Methods: From the records referring to the period of June, 2001 to August, 2007, there were 1 345 patients with facial fractures. Of this total, 116 patients with mandibular fracture were selected for this study and the items analysed were: age, gender, mandibular fracture site, etiology and period of the year. Results: It was found that 86.2% of the sample were men. The most prevalent age was 20 to 29 years old representing 36.2%, and the most affected mandibular sites were the body, with 29 cases (25%, and the condyle, with 26 cases (22.4%. The most common cause of fractures was the physical aggression representing 37.1%. The period of the year with the highest incidence of mandibular fractures was the summer, with 38 cases (32.8%. Conclusion: It was therefore observed that the patients with mandibular fracture assisted at Pronto-Socorro Municipal de Pelotas, Rio Grande do Sul, Brazil, were generally men, 20 to 29 years old with mandibular body fracture and they were victims of physical aggression.

    In the US Southwest, evidence of increased future drought severity and duration in the context of climate change has been detected. Considering the already difficult water distribution and allocation strategies within the region, we are investigating the Costilla Creek, a tributary to the Rio Grande. The catchment is located in Costilla county in Colorado from where on runoff is crossing boundaries between Colorado and New Mexico three times before its confluence with the Rio Grande in New Mexico. Water allocation is governed by an interstate compact between Colorado and New Mexico. While the states have been relatively successful in complying with the compact’s allocation rules, the Costilla Creek catchment has experienced interstate upstream/downstream conflict, mainly during irrigation seasons. Whether or not the states will be able to avert conflict in the future and maintain compliance with the compact, is a critical question. The situation in the relatively small catchment is not unique. Various interstate watersheds, including the entire Rio Grande basin, the La Plata, Arkansas, and Colorado, are expected to face similar impacts from climate change, yet the water compacts that govern them may not be structured to adapt to these conditions. Looking at the Costilla Creek offers a valuable starting point for understanding how to model these effects across various basins. We have developed a lumped-parameter rainfall-runoff model including snow storage of the Costilla Creek watershed. Temperature and precipitation data from NCRS - SNOTEL stations together with USGS gauging station data were utilized for model calibration and validation. ISCCP solar radiation data and temperature data were used to estimate irrigation water demand in irrigated agriculture. The model is driven by the IPCC SRES A2 scenario. GCM ensemble averaged temperature / precipitation trends were extracted for the upper Rio Grande region. 50 year precipitation simulations were created using a

    Invasive species and ecohydrological disturbances are imperiling native riparian ecosystems. Adaptable, resilient exotic competitors including tamarisk have colonized many waterways in the western US. Alteration of the natural flow regime due to water diversions is expected to be exacerbated by climate change in this region, confounding restoration efforts. Climate change may also increase the likelihood of other disturbances, including extreme weather events (drought, floods, temperatures). We investigate how hydrological and meteorological variability impact water use by tamarisk communities that have overtaken native riparian vegetation. We have collected more than a decade of complete growing season eddy covariance evapotranspiration (ET) and water table (WT) elevation data at two sites along the Rio Grande corridor of central New Mexico, USA. Conditions have ranged from extreme drought to exceedingly wet years with extensive overbank flooding, and from record setting warm to cold temperatures. Severe to extreme droughts persisted throughout 2002 and 2003. Abundant snowpacks and wetter conditions led to extensive flooding early in the 2005 and 2008 growing seasons. Along with a return to intense drought conditions, extreme temperatures struck New Mexico in 2011. A deep freeze in early February followed by an extraordinarily late, extended hard freeze at the onset of the growing season was then succeeded by the warmest summer in the state's 117 year record. We present how water use by the replacement communities responds to droughts, flooding, and extreme temperatures, all of which are expected to increase in frequency, and speculate how these disturbances will affect native riparian ecosystems.

    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.

    2016-01-01

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

    1988-01-01

    One hundred twenty-three of 300 blood samples (41%) taken from Rio Grande wild turkeys (Meleagris gallopavo intermedia) from three locations in southern Texas (Welder Wildlife Refuge, Chaparrosa Ranch, and Campo Alegre Ranch) and subinoculated into domestic broad-breasted white turkey poults were positive for a Plasmodium (Novyella) sp. Analysis of blood films from 350 turkeys revealed Haemoproteus meleagridis in 76% of the birds. A significantly greater mean parasite intensity was observed in birds from Welder Wildlife Refuge. Birds from the Campo Alegre Ranch exhibited a significantly higher prevalence of H. meleagridis than birds from Chaparrosa. The Plasmodium sp. was infective for canaries (Serinus canaria), bobwhites (Colinus virginianus), and ring-necked pheasants (Phasianus colchicus), but would not produce infection in white leghorn chickens (Gallus gallus) or Coturnix quail (Coturnix coturnix). Attempts to infect Culex tarsalis and C. pipiens were unsuccessful. Asexual erythrocytic synchrony was not observed when blood-induced infections were monitored in two domestic turkey poults every 4 hr for 72 hr. Exoerythrocytic stages were not found upon examination of impression smears and tissue samples taken from brain, liver, spleen, kidney, lung, and bone marrow. The Plasmodium sp. is most similar morphologically to three species in the subgenus Novyella, P. hexamerium, P. vaughani, and P. kempi. The most striking similarities are to P. hexamerium, and involve mean merozoite number, erythrocytic schizont location, and vertebrate host susceptibility. It differs from P. vaughani in being able to infect turkeys and in type of parasitized erythrocytes. Differences to P. kempi include mean merozoite number, and ability to infect pheasants, and its inability to develop in C. pipiens and C. tarsalis.

    Full Text Available O objetivo deste trabalho foi elaborar e testar modelos para a estimativa de rendimento de arroz irrigado, no Estado do Rio Grande do Sul. O estudo foi realizado com dados meteorológicos de temperatura mínima do ar, radiação solar global e dados de estatísticas agrícolas de rendimento de arroz irrigado, das seis regiões orizícolas do Rio Grande do Sul, referentes às safras 1982/1983 até 2005/2006. Foram feitas análises de tendência tecnológica dos rendimentos, e foram estabelecidos os indicadores agrometeorológicos para o ajuste de modelos de estimativa de rendimento de arroz irrigado, para o Rio Grande do Sul. Existe tendência tecnológica de aumento nos rendimentos de arroz irrigado no Estado. As variáveis meteorológicas avaliadas - dias com temperatura mínima do ar inferior a 15°C e radiação solar global - podem ser usadas como indicadores do rendimento de arroz irrigado. Os modelos agrometeorológicos elaborados para as seis regiões orizícolas e para o Estado do Rio Grande do Sul apresentam características de precisão, fácil implementação e baixo custo e podem, portanto, ser introduzidos ao programa nacional de previsão de safras.The objective of this work was to elaborate and test models to estimate the irrigated rice yield, in Rio Grande do Sul State, Brazil.

    In 1991, the Texas Natural Resource Conservation Commission (TNRCC) was mandated by the Texas Clean Rivers Act (Senate Bill 818) to assess water quality of rivers in Texas. Recent efforts to collect information for the assessment of water quality in the Rio Grande/Rio Bravo Basin have involved Federal agencies on both sides of the 1,248-mile U.S.-Mexico border?U.S. Environmental Protection Agency, U.S. Geological Survey (USGS), Secretaria de Desarollo Social (Secretary for Social Development, Mexico), National Water Commission of Mexico, and International Boundary and Water Commission?as well as State and local agencies in a spirit of international cooperation. Substantial efforts have been made to gather data needed to determine the quality of water and ecological status of the Rio Grande/Rio Bravo, especially at sites along the border (fig. 1). The purpose of this report is to assess selected historical data of trace elements and organic compounds in riverbed sediments of the Rio Grande/Rio Bravo, and of the Pecos River and the Arroyo Colorado in Texas.

    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

    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.

    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)

  3. A critical evaluation of coastal erosion in Rio Grande do Sul, Southern Brazil

    2004-01-01

    Full Text Available Evidences of coastal erosion in Rio Grande do Sul have been obtained by three methods: (a analysis of the long-term morphodynamics and stratigraphy of coastal barriers, (b annual shoreline mapping using the Differential Global Positioning System (DGPS, and (c local beach profile measurements. The first method reflects coastal erosion as continuity of the geological evolution in the last 5 ka, taking place mainly along the southern half of gentle coastal projections. The second method represents a shorter temporal scale and indicates that approximately 80% of the coast is eroding. Beach profiling has been measured in very few places that are distant from each other since the early 1990s; consequently, their results reflect local and very short time shoreline behavior. A critical evaluation of published data addressing coastal erosion in Rio Grande do Sul strongly suggests that short and long term negative balance on the sediment budget is the main cause of erosion along this coastline.

    The article analyzes conflicts and interests at one of Rio Grande de Sul's main centers for medical science, the Faculdade de Medicina de Porto Alegre. It explores the meaning and impact of the emergence of this specific, exclusive field of knowledge in a state where positivist principles of professional freedom were adopted by successive administrations during the early period of the Republic. Physicians there launched an entrenched war to uphold the principles of science over faith and politics, challenging the positivism of the party which held power in Rio Grande do Sul throughout the years. This perspective grew and developed in a climate of conflict and doubts among physicians, within a political context that differed from the rest of Brazil.

    State wildlife agencies have translocated thousands of wild turkeys (Meleagris gallopavo) since the 1930s to reestablish this species. Because of threats to the domestic poultry industry and wild birds, screening for selected infectious agents has become routine since the early 1980s. One of the principal sources for Rio Grande wild turkeys (M. gallopavo intermedia) for translocation purposes was the Edwards Plateau of Texas (USA). Unfortunately, turkey abundance has declined in the southern Edwards Plateau since the late 1970s. Surprisingly few studies have addressed wild turkeys in this region, perhaps reflecting its status as the heart of Rio Grande turkey range. We surveyed 70 free-living Rio Grande wild turkeys from Bandera and Kerr counties, Texas, for evidence of exposure to Salmonella typhimurium, S. pullorum, Mycoplasma gallisepticum, M. meleagridis, M. synoviae, Chlamydophila psittaci, and the avian influenza, Newcastle disease, turkey corona, and reticuloendotheliosis viruses. Of these, 80% (56) were seropositive for both M. gallisepticum and M. synoviae on the serum plate antigen test. Ten of these individuals (14% of total) were positive for M. synoviae by hemagglutination inhibition testing. All other serologic tests were negative. Two adult females sampled in Kerr County, whose body mass was significantly less than that of other adult females trapped in the area, tested positive for reticuloendotheliosis virus (REV) proviral DNA on polymerase chain reaction. Reticuloendotheliosis virus was isolated from one of these individuals. The pathogenesis, transmission, and/or population-level influences of M. gallisepticum, M. synoviae, and REV in Rio Grande wild turkeys deserves further study.

    New K sbnd Ar age determinations on mid-Oligocene to Pleistocene volcanic and shallow intrusive rocks from the central Rio Grande rift permit a more detailed understanding of the tectonic and magmatic history of the rift. Initial extension in the region of the central rift may have begun prior to 27 m.y. ago. By 25 m.y. ago broad basins existed and were filling with volcaniclastic sediments derived mainly from volcanic centers in the San Juan and Questa areas. Continued tectonic activity narrowed these basins by 21-19 m.y. ago, indicated in the Santa Fe area by tilting and faulting that immediately postdate 20-m.y.-old latite. Uplift of the Sangre de Cristo, Sandia, and Nacimiento Mountains shed clastic debris of the Santa Fe Group into these basins. Early rift magmatism is characterized by an overlap of mid-Tertiary intermediate intrusive and extrusive activity, extending to 20 m.y. ago, with mafic and ultramafic volcanism, ranging from 25 to 19 m.y. Both volcanism and tectonic activity were minimal during the middle Miocene. About 13 m.y. ago renewed volcanic activity began. Tectonism commenced in the late Miocene, resulting in the present, narrow grabens. The term "Rio Grande rift" should be restricted to these grabens formed during post-mid-Miocene deformation. Widespread eruption of tholeiitic and alkali olivine basalts occurred 3-2 m.y. ago. The Rio Grande drainage system was integrated 4.5-3 m.y. ago, leading to the present erosional regime. These intervals of deformation and magmatism correspond generally with a similar sequence of events in the Basin and Range province south of the Colorado Plateau. This similarity indicates that the Rio Grande rift is not a unique structure in the southwestern U.S., and must be related to the larger context of the entire Basin and Range province.

    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. A previous report (LA-12767-MS) summarizes the results of the experimental modal analyses. This report summarizes the numerical analyses of the bridges and compares the results of these analyses to the experimental results.

    Paracoccidioides brasiliensis, a dimorphic pathogenic fungus, causes the principal form of systemic mycosis in Brazil. The literature furnishes only limited data on the ecology of this fungus in the state of Rio Grande do Sul, the southernmost state of Brazil. The purpose of this study was to evaluate the prevalence of fungal infection in wild animals, using serological tests and using the animals as sentinels of the presence of P. brasiliensis in three specified mesoregions of Rio Grande do Sul. A total of 128 wild animals from the three mesoregions were included in the study. The serum samples were evaluated by immunodiffusion and the enzyme-linked immunosorbent assay (ELISA) technique to detect anti-gp43 antibodies from P. brasiliensis. Two conjugates were tested and compared with the ELISA technique. Although no positive samples were detected by immunodiffusion, 26 animals (20%), belonging to 13 distinct species, were found to be seropositive by the ELISA technique. The seropositive animals were from two mesoregions of the state. The results were similar according to the gender, age, and family of the animals, but differed significantly according to the conjugate used (p animals from the state of Rio Grande do Sul are exposed to P. brasiliensis suggests that the fungus can be found in this region despite the often-rigorous winters, which frequently include below-freezing temperatures.

    Although it has been documented that wildlife in the Rio Grande Valley (RGV) contain increased concentrations of organochlorine (OC) contaminants, particularly DDE, little has been published on residues of toxaphene throughout this major North American watershed. In this study, 28 liver composites from adult swallows (Petrochelidon spp.) collected along the Rio Grande from 1999 through 2000 were analyzed for toxaphene residues using congener-specific gas chromatography-electron-capture negative ionization-mass spectrometry. Estimated total toxaphene concentrations ranged from 12 to 260 ng/g wet wt and were highest in samples from the lower RGV near Llano Grande Lake in Hidalgo and Cameron counties (Texas). Toxaphene congener profiles were relatively invariant throughout the watershed and were dominated by 2,2,5-endo,6-exo,8,8,9,10-octachlorobornane (P-42a or B8-806) with lesser amounts of several other Cl(7)-Cl(9) compounds, many of which remain unidentified. Petrochelidon spp. liver profiles appear to be intermediate in complexity between those in invertebrates and fish (more complex) and mammals (less complex) and differs somewhat from those reported for other avian species. In addition to other legacy OC contaminants, toxaphene residues were most concentrated in the lower RGV and accumulated at up to hundreds of parts per billion in these insect-eating birds, underscoring their utility as avian bioindicators of persistent organic pollutants.

    The alluvial aquifer within a 160-acre area of the Rio Grande de Manati alluvial plain was investigated to evaluate its potential as a water-supply source for the Barrios Rio Arriba Saliente and Pugnado Afuera, municipio of Manati, Puerto Rico. Analysis of well boring samples and the results of electric resistivity surveys indicate that the average thickness of the unconsolidated alluvial deposits in the study area is about 100 to 110 feet. The alluvium is a mixture of sand and gravel, which generally has a porosity of 0.2 to 0.35. Short-duration pump tests in small-diameter piezometers indicate that the alluvial aquifer has a hydraulic conductivity of about 200 feet per day and a transmissivity of about 7,900 feet squared per day. Analyses of water levels in piezometers, combined with stage measurements at a series of surveyed reference points along the Rio Grande de Manati channel, indicate that the water-table gradient in the alluvial aquifer is about 0.001, and that ground-water flow is generally from south to north, in the general direction of river flow. The water-table data indicate that the Rio Grande de Manati is the principal source of ground-water recharge to the alluvial aquifer in the study area. Because base flow for the Rio Grande de Manati is usually greater than 44 cubic feet per second, a continuous withdrawal rate of 0.5 to 1.0 cubic foot per second (225 to 450 gallons per minute) from a production well is possible. Chemical analysis of a ground-water sample indicates that the alluvial aquifer water meets U.S. Environmental Protection Agency secondary standards for selected constituents. Bacteriological analysis of ground-water samples indicates that the ground water contains little or no fecal coliform or fecal streptococcus bacteria. Although long-term data from upstream of the study area indicate high levels of fecal coliform and fecal streptococcus prior to 1996, bacteriological analyses of Rio Grande de Manati water samples obtained during

    Full Text Available We quantify uncertainty in the impacts of climate change on the discharge of Rio Grande, a major tributary of the Paraná River 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 greenhouse-gas emission scenarios (A1b, A2, B1, B2 and increases in global mean air temperature of 1 to 6° C for the HadCM3 GCM (Global Circulation Model 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 Rio Grande Basin. Based on simulations using HadCM3, mean annual river discharge increases, relative to the baseline or control run 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 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.

  9. Geothermal resources of rifts: A comparison of the rio grande rift and the salton trough

    1983-05-01

    The Rio Grande Rift and the Salton Trough are the best developed rift systems in the United States and both share many features common to rifts in general, including geothermal resources. These two rifts have different tectonic and magmatic histories, however, and these differences are reflected in the nature of their geothermal resources. The Salton Trough is a well developed and successful rift. It is the landward extension of the Gulf of California spreading center, which has separated Baja, California, from the remainder of Mexico. Quaternary silicic magmatization has occurred and several of the geothermal resources are associated with recent rhyolitic intrusions. Such resources tend to be high temperature (> 200°C). Greenschist facies metamorphism has been observed in several of the geothermal wells. Localized upper crustal melting is a distinct possibility and there is increasing speculation that very high temperature (> 300°C) geothermal fluids may underlie a large portion of the central trough at depths in excess of 4 km. Low temperature geothermal resources associated with shallow hydrothermal convection are less common and tend to be located on the flanks of the trough or in the Coachella Valley to the north of the zone of active rifting. In contrast, the Rio Grande Rift is less well developed. Recent volcanism consists primarily of mantle-derived basalts, which have not had sufficient residence time within the crust to generate significant crustal melting. The geothermal resources within the Rio Grande Rift do not correlate well with these young basalts. Rather, the quantity of geothermal resources are low temperature (geothermal exploration targets.

    2014-01-01

    Common Snook Centropomus undecimalis were once abundant off the Texas coast, but these populations are now characterized by low abundance and erratic recruitment. Most research concerning Common Snook in North America has been conducted in Florida and very little is known about the specific biology and habitat needs of Common Snook in Texas. The primary objective of this study was to describe the habitat use patterns of juvenile Common Snook and their role in the fish assemblage in the lower portion of the Rio Grande, Texas. Secondarily, we documented the relationship between age and juvenile reproductive development. Fish were collected during January–March 2006 from the lower 51.5 km of the Rio Grande using a bottom trawl and boat-mounted electrofisher. Measurements of water quality and other habitat traits were recorded at each sampling site. We captured 225 Common Snook exclusively in freshwater habitats above river kilometer 12.9. The distribution of juvenile Common Snook was not random, but influenced primarily by turbidity and dissolved oxygen. Sex differentiation and gonadal development based on histological examination of gonads established that age-1 and age-2 Common Snook were juvenile, prepubertal males. There was no difference between the age groups in their overall distribution in the river. However, age-2 Common Snook were associated with deeper areas with faster currents, higher conductivity, and steeper banks. Overall, Common Snook in the lower Rio Grande show substantial differences in habitat use than their counterparts in other parts of the range of the species, but it is unclear whether this is due to differences in habitat availability, behavioral plasticity, or some combination thereof.

    1999-04-01

    Regional assessments of water resources under global climate change require models that can resolve management, land use, and climate effects. Los Alamos National Laboratory is developing a coupled model of water resources that places a river basin in its global context. The upper Rio Grande basin above El Paso, Texas is the testbed for this model. The model structure and computational approach are emphasize and issues such as nonlinear feedback between components and spatial and temporal scaling of processes are discussed. Using simulations of regional meteorology, the effects of high spatial resolution simulations on the distribution of precipitation are demonstrated.

    Regional interpretation of the stratigraphy, faulting, fracturing, and hydrodynamics in Archuleta, Conejos, Mineral, and Rio Grande Counties in southern Colorado indicates that significant reserves of hydrocarbons could exist in subtle trapping situations within the Cretaceous sequences. The presence of Price-Gramps field (7 million bbl of oil ultimate recoverable), which produces primarily from the Dakota Formation, is presently anomalous in this area but is indicative of existing hydrocarbon potential. Hydrocarbon shows from drilled wells and outcrops suggest that significant quantities of hydrocarbons are present in this area, sourced both from the San Juan basin to the south and west, and from more local areas for fractured reservoirs.

    This paper presents results of an assessment of the quality research of endocrinology referrals in the public health system in the state of Rio Grande do Sul. From the analysis of 4,458 requests for endocrinology referrals, it was found that 15% of referrals had insufficient information for evaluation and 71% showed no clinical justification for authorization of referencing. The partial results of the study indicated that the lack of information makes it impossible to clinically regulate these requests. The use of referencing protocols associated with telemedicine tools can assist doctors in primary health care in the clinical management and make access to specialized services more equitable and timely.

    Full Text Available We have been searching for evidence of Chagas disease in mummified human remains. Specifically, we have looked for evidence of alteration of intestinal or fecal morphology consistent with megacolon, a condition associated with Chagas disease. One prehistoric individual recovered from the Chihuahuan Desert near the Rio Grande exhibits such pathology. We present documentation of this case. We are certain that this individual presents a profoundly altered large intestinal tract and we suggest that further research should focus on confirmation of a diagnosis of Chagas disease. We propose that the prehistoric activity and dietary patterns in Chihuahua Desert hunter/gatherers promoted the pathoecology of Chagas disease.

    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.

    Full Text Available OBJECTIVE Collection of triatomines in domestic, peridomestic and sylvatic environments in states of Bahia and Rio Grande do Sul, Northeastern and Southern Brazil respectively, and isolation of Trypanosoma cruzi strains. METHODS First, the captured triatomines were identified using insect identification keys, then their intestinal content was examined by abdominal compression, and the samples containing trypanosomatid forms were inoculated in LIT medium and Swiss mice. RESULTS Six triatomine species were collected in cities in Bahia, namely Panstrongylus geniculatus (01, Triatoma melanocephala (11, T. lenti (94, T. pseudomaculata (02, T. sherlocki (26 and T. sordida (460, and two in cities in Rio Grande do Sul, namely T. circummaculata (11 and T. rubrovaria (115. Out of the specimens examined, T. cruzi was isolated from 28 triatomine divided into four different species: T. melanocephala (one, T. lenti (one, T. rubrovaria (16 and T. sordida (10. Their index of natural infection by T. cruzi was 6.4%. CONCLUSIONS The isolation of T. cruzi strains from triatomines found in domestic and peridomestic areas shows the potential risk of transmission of Chagas disease in the studied cities. The maintenance of those T. cruzi strains in laboratory is intended to promote studies that facilitate the understanding of the parasite-vector-host relationship.

    Full Text Available Paracoccidioidomycosis (PCM is a systemic mycosis caused by the fungus Paracoccidioides brasiliensis and is endemic to Brazil. The aim of this study was to perform a retrospective analysis of the PCM cases in the countryside south of Rio Grande do Sul, Brazil. The files from four histopathology laboratories located in the city of Pelotas were obtained, and all of the epidemiological and clinical data from the PCM diagnosed cases were collected for analysis. A total of 123 PCM cases diagnosed between 1966 and 2009 were selected. Of these patients, 104 (84.5% were male, and 17 were female. The patients ranged from 02 to 92 years of age. Fifty-two cases (41.9% were obtained from the oral pathology laboratory, and the remaining 71 cases (58.1% were obtained from the three general pathology laboratories. Of all of the patients studied, 65.2% lived in rural zones and worked in agriculture or other related fields. Data on the evolution of this disease was available for 43 cases, and the time frame ranged from 20 to 2920 days (mean = 572.3 days. An accurate diagnosis performed in less than 30 days only occurred in 21% of the cases. PCM is endemic to the countryside of Rio Grande do Sul. Therefore, it is recommended that PCM be included as a differential diagnosis, mainly for individuals between 30 and 60 years of age, living in rural zones and who have respiratory signs and associated-oropharyngeal lesions.

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

    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.

    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 O{sub 2} and NO{sub 3}{sup -} 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.

    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

  17. Phenolic compounds in Merlot wines from two wine regions of Rio Grande do Sul, Brazil

    Full Text Available In Brazil, the grape and wine production takes place mainly in the state of Rio Grande do Sul, and the region "Serra" is known as the traditional wine region. In the last years, new areas have emerged, with emphasis for the Campanha region; the red wines from this region have low acidity, little color intensity, and are wines to drink while young, even when produced from grape varieties such as Merlot and Cabernet Sauvignon. The objective of this study was to evaluate the influence of different maceration types on the phenolic compounds of Merlot wines made with grapes produced in two regions of Rio Grande do Sul, Serra and Campanha, as well as to identify the key differences between the wines produced. The localization of the vineyards seems to have more influence on the wine characteristics than the maceration type. The color due copigmentation was an important aspect in the wines made with short maceration. The effect of extended maceration was different than the expected for the Campanha region wines; the extended maceration increased the extraction of tannins resulting in greater color intensity and a greater amount of anthocyanins. The pH control seems to be a key factor for the Campanha region wines.

    A long-term aquifer test was conducted near the Rio Grande in Albuquerque during January and February 1995 using 22 wells and piezometers at nine sites, with the City of Albuquerque Griegos 1 production well as the pumped well. Griegos 1 discharge averaged about 2,330 gallons per minute for 54.4 days. A three-dimensional finite-difference ground-water-flow model was used to estimate aquifer properties in the vicinity of the Griegos well field and the amount of infiltration induced into the aquifer system from the Rio Grande and riverside drains as a result of pumping during the test. The model was initially calibrated by trial-and-error adjustments of the aquifer properties. The model was recalibrated using a nonlinear least-squares regression technique. The aquifer system in the area includes the middle Tertiary to Quaternary Santa Fe Group and post-Santa Fe Group valley- and basin-fill deposits of the Albuquerque Basin. The Rio Grande and adjacent riverside drains are in hydraulic connection with the aquifer system. The hydraulic-conductivity values of the upper part of the Santa Fe Group resulting from the model calibrated by trial and error varied by zone in the model and ranged from 12 to 33 feet per day. The hydraulic conductivity of the inner-valley alluvium was 45 feet per day. The vertical to horizontal anisotropy ratio was 1:140. Specific storage was 4 x 10-6 per foot of aquifer thickness, and specific yield was 0.15 (dimensionless). The sum of squared errors between the observed and simulated drawdowns was 130 feet squared. Not all aquifer properties could be estimated using nonlinear regression because of model insensitivity to some aquifer properties at observation locations. Hydraulic conductivity of the inner-valley alluvium, middle part of the Santa Fe Group, and riverbed and riverside-drain bed and specific yield had low sensitivity values and therefore could not be estimated. Of the properties estimated, hydraulic conductivity of the upper part of

    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.

    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.

  12. 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.

  14. Floodplain construction of the Rio Grande at El Paso, Texas, USA: response to Holocene climate change

    Hall, Stephen A.; Peterson, John A.

    2013-04-01

    The Rio Grande is one of the larger rivers in North America, and the development of its floodplain is related to Holocene climate and climate change. The late Pleistocene through early Holocene channel is characterized by a meander or braided system with lateral cutting and backfilling, resulting in the valley-wide deposition of massive to cross-bedded, fine-to-medium textured sand. The late Pleistocene-early Holocene floodplain is also the sand source for the adjacent Bolson sand sheet. The sand sheet stopped accumulating new sand 5000 yrs ago, an event directly related to the shutting off of the sand supply caused by the deposition of overbank muds that covered and sealed the floodplain surface. During the middle Holocene, the river may have dried intermittently with the floodplain becoming deflated and local sand dunes forming on the floodplain. After 5000 yrs the climate was less arid and the river shifted to a regime of increased flooding and overbank deposition of silt and clay. By 2500 yrs, a late Holocene period of wet climate resulted in further overbank deposition and the formation of a cumulic Mollisol across the floodplain, the Socorro paleosol. The period of wet climate corresponds to the Audubon Neoglacial and active rock glaciers in the southern Rocky Mountains, speleothem growth in nearby caves, and other evidence for wet-cool conditions in the region. After 1000 yrs, the climate became drier, and the deposition and accumulation of overbank muds by the flooding Rio Grande came to a halt. Even though the river has flooded often in historic times, and presumably during late prehistoric times as well, there is little evidence for deposition of overbank sediments on the floodplain since A.D. 1000. Accordingly, the present-day surface of the Lower Valley is ten centuries old. Three channels occur on the US side of the Lower Valley floodplain, and during the past 2500 yrs stream flow has shifted from one to the other by the avulsion process of channel

    Full Text Available Springs are outcrops of aquifers surface, and the water cycle in this environment pass through the recharge, generally defined as the amount of water added to the aquifer, which may occur locally from rainwater infiltration. This study uses the Water Table Fluctuation (WTF method to estimate the direct recharge and a groundwater balance to estimate the deep recharge on unconfined aquifers. The WTF method employs data of the aquifer water levels and its specific yield to estimate the direct recharge. The groundwater balance considers the direct recharge estimated by the WTF method, as the water input in the system and outputs as the base flow and deep recharge. The recharge was estimated at four areas at the watershed of Alto Rio Grande city, Minas Gerais (MG state, in Brazil. The direct recharge estimate was 121.11; 64.62; 83.99; 152.46 (mm/year for the L1, L2, M1 and M2 areas. The effect of the presence of forest in the recharge area can prevail over slope of relief, allowing more direct recharge, even in sources with steeper relief. The runoff from the springs in the study period exceeded the direct recharge, indicating a situation in which the saturated zone feeds the vadose zone. The annual flow was above the direct recharge pointing a situation of over exploitation of the aquifer, a non sustainable situation. The specific yield of the aquifers could also have been underestimated.As nascentes são afloramentos dos aquíferos superficiais, e o ciclo da água neste ambiente passa pela recarga que é definida, de maneira geral, como a quantidade de água que é acrescentada ao aquífero, podendo ocorrer localmente a partir da infiltração das águas das chuvas.

    Basins of the Rio Grande rift have long been studied both for their record of rift development and for their potential as host of natural resources. Early workers described the basin geomorphology and the character of infilling sediments (e.g. Siebenthal, 1910; Bryan, 1938; Speigel and Baldwin, 1963), and subsequent research compilations provided general stratigraphic and tectonic overviews of rift basins and described their geophysical characteristics within the crust (Hawley, 1978; Riecker, 1979; Baldridge et al., 1984; Keller, 1986). Subsurface knowledge gained from hydrocarbon exploration activities coupled with detailed surface studies of basins and their flanking uplifts were presented in Geological Society of America (GSA) Special Paper 291, edited by Keller and Cather (1994a).

Daily, activities practiced in schools are mostly related to recreational and sportive games, gymnastics and walks. The pedagogical approaches adopted by teachers are the physical activity approach and the humanist approach. As a conclusion, teachers’pedagogical practice is focused on Physical Education teachers’s valorization as a school curricular content and search for changing their practice in qualified healthy activities.

  12. An international borderland of concern: Conservation of biodiversity in the Lower Rio Grande Valley

    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 aimed to evaluate the genetic and cytological diversity and stability of 35 cherry tree accessions collected in Rio Grande do Sul. We used 15 RAPD (Random Amplified Polymorphic DNA molecular markers and performed cytological analysis and number count of anthers. Analyses of genetic diversity allowed the separation of accessions into four groups, resulting in an average of 8.93 bands per primer amplified, 7.89 polymorphic bands, 88.08% of polymorphism and 86% of genetic similarity. Cytological analyses of gametic cells allowed for the characterization of accessions as diploids with n=11. In these, the average of meiotic cells considered normal was 82.12%; average pollen viability was 92.44% and in vitro germination was 40.26%; the average number of anthers was 161.85 anthers/flowers. Therefore, the accessions evaluated showed high genetic similarity and cytological stability and can be used in commercial plantations or hybridizations.

    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.

    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.

    Full Text Available Abstract Background Self-medication is the use of medication without prescription, orientation, or supervision of a physician or dentist. Self-medication might become a serious health problem. The purpose of this study was to identify the prevalence and factors associated with self-medication among first and last-year students enrolled in healthcare and non-healthcare programs. Methods A cross-sectional study was conducted at Universidade Federal do Rio Grande (FURG, state of Rio Grande do Sul, Brazil. Of 830 students in the sample, 95% answered the questionnaire – 789 students enrolled in 10 undergraduate programs. Mean age was 22 ± 6.17 years. The students answered a questionnaire covering socio-economic and demographic variables, use of medication, and medication knowledge. Information was collected on the conditions treated with medication, the medications used, and attitude towards self-medication. Results Of 789 students, 86.4% self-medicated (88.5% of 446 healthcare students. There were no significant differences in self-medication between healthcare and non-healthcare students, nor between first and last-year students. Bivariate and multivariate analyses showed a significant association between self-medication and having children (p = 0.01, having a home pharmacy (p p = 0.01. The most frequently used active ingredients were acetaminophen (paracetamol, dipyrone, aspirin, phytotherapic compounds, and tea. Illicit drug use was significantly associated with self-medication in the multivariate analysis. Conclusion The fact that being a healthcare student was associated with higher medication knowledge, but not with less self-medication, suggests that medication knowledge might contribute to increase self-medication. This should be taken into account when designing educational interventions relating to self-medication.

  1. Pathogenic landscape of transboundary zoonotic diseases in the Mexico-US border along the Rio Grande

    Full Text Available 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 millions of people live in this transboundary region but also a substantial movement 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.

    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.

    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)

    Full Text Available A ceratoconjuntivite infecciosa (CI, embora raramente fatal, resulta em perdas econômicas significativas para os rebanhos bovinos e ovinos. Os principais agentes causadores dessa enfermidade são Moraxella bovis e Moraxella ovis. Em 2007 foi descrita uma nova espécie também responsável pela CI e denominada Moraxella bovoculi, que até o presente momento, não havia sido relatada no Brasil. Assim, objetivou-se com este trabalho caracterizar e distinguir 54 isolados de Moraxella spp. de amostras clínicas oriundas de 34 bovinos e 17 ovinos, encaminhadas ao Laboratório de Bacteriologia da Universidade Federal de Santa Maria no período de 1990 a 2011, visando a identificação de M. bovoculi. A distinção dos isolados foi fundamentada nas características genotípicas, pela amplificação parcial da região intergênica 16S-23S e clivagem dos produtos da amplificação com enzima RsaI. Como resultados, 25 (46% isolados foram caracterizados como M. bovis, 17 (32% como M. ovis e 12 (22% como M. bovoculi. Logo, conclui-se que M. bovoculi encontra-se presente no rebanho bovino do Rio Grande do Sul e, portanto, no Brasil.

  19. Hydrochemical tracers in the middle Rio Grande Basin, USA: 1. Conceptualization of groundwater flow

    Science.gov (United States)

    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.

A Planície Costeira do Rio Grande do Sul possui um sistema de lagoas que teve origem nos processos de transgressão e regressão marinha durante o Pleistoceno e Holoceno. A gênese destes corpos de água tem um importante papel na sua caracterização ecológica e biodiversidade. Para efeito de estudo, o litoral rio-grandense pode ser dividido em três áreas que se distinguem, especialmente, quanto ao seu uso e impacto antrópico: litoral norte, de Torres a Quintão, se caracteriza pela concentração de veranistas; no litoral médio, até a Lagoa do Peixe e litoral sul, ao sul da barra da Lagoa dos Patos, há predomínio de atividades agrícola e pastoril, com uso da águas para irrigação. As Unidades de Conservação existentes na costa não contribuem com a preservação destes ecossistemas. O mau uso das lagoas tem contribuído para sua eutrofização, destruindo a biodiversidade, ainda pouco conhecida, e acelerando o processo de envelhecimento natural.PALAVRAS-CHAVE: lagoas costeiras; patrimônio ambiental; turismo; sul do Brasil. ABSTRACT:Lakes and coastal lagoons are distributed in the several continents. The Coastal Plain of Rio Grande do Sul has a system of coastal lake that was shaped by Pleistocene and Holocene transgression and regression phases.

    Full Text Available We provide recent information on the richness of mammals along the agroecosystems of the Rio da Várzea Basin, Rio Grande do Sul, Brazil. We used different field techniques to confirm the occurrence of 46 mammal species in this area. Nine species are threatened in at least one of the three “red lists” at state, national and global levels. Adding the up-to-date results obtained in the field to available data, mainly for conservation units, we present a richness of 85 species recorded for the basin. This number represents about 50% of mammals documented for Rio Grande do Sul state. The results suggest the importance of maintaining protected areas in altered regions, confirming the relevance of inventories of local fauna as a first approach to specific studies addressed to distribution, systematics, cytogenetics, physiology, population and community ecology.

    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 The purpose of the present work was to evaluate the environmental quality of Marcelino, Pinguela, Peixoto, Palmital, Malvas and Do Passo lakes, interconnected by canals and located in the district of Osório, RS. In this context, 29 physical and chemical variables were analyzed with sampling carried out in January, May, July and October 1997 to verify the environmental quality of the system and the existence of a gradient of quality. Canonical Analysis was applied to the data of all environmental variables measured, and showed that the lakes had different characteristics as a consequence of the organic pollution received. Marcelino lake received continuous input of organic matter from the sewage treatment works in the town of Osório, whereas Peixoto, Pinguela, Palmital, Malvas and Do Passo lakes resembled other water bodies described in the region, not showing, so far, signs of degradation caused by the input of effluents. Principal Component Analysis selected environmental element were directly linked to organic pollution, that reflected sequential non-recent effects of contamination.O propósito do presente estudo foi avaliar a qualidade ambiental das lagoas Marcelino, Pinguela, Peixoto, Palmital, Malvas e Lagoa do Passo, ecossistemas interligados nesta seqüência por canais e localizados próximos a cidade de Osório, Rio Grande do Sul. Foram analisadas vinte e nove variáveis ambientais físicas e químicas no período de janeiro, maio, julho e outubro de 1997. Constatou-se, através de uma análise de discriminantes canônicos utilizando-se as variáveis ambientais, que as lagoas apresentaram características limnológicas diferenciadas em função do aporte dos efluentes urbanos: a lagoa Marcelino mostrou contaminação orgânica e foi separada das demais lagoas evidenciando um gradiente de qualidade ambiental. Posteriormente, uma análise de componentes principais diferenciou as estações amostrais selecionando descritores ambientais

    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. O artigo finaliza documentando a forte compressão salarial existente no magistério em comparação ao observado no mercado de trabalho gaúcho e paulista para os profissionais com curso superior.

Através de uma amostragem não probabilística, foi realizado um estudo etnográfico em 13 propriedades de oito municípios pertencentes às regiões da Grande Porto Alegre, Serra, Planalto Médio, Depressão Central e Serra do Sudeste. A pesquisa diagnosticou uma grande diversidade de plantas cultivadas de origem remota, mantidas nas propriedades dos agricultores tradicionais através de bancos de sementes. Ao todo, foram identificadas 39 espécies de plantas, distribuídas em 12 famílias botânicas, totalizando 258 apontamentos de plantas cultivadas crioulas no total dos entrevistados. A preferência da utilização de sementes crioulas, de acordo com relatos dos agricultores entrevistados, foi atribuída principalmente a características como a adaptabilidade, valorização dos costumes, o sabor e qualidade das variedades tradicionais, além do baixo custo de produção. Em relação às dificuldades de sua manutenção, as mais freqüentes foram o desinteresse das novas gerações e a dificuldade em trocar e obter sementes. Foram, ainda, diagnosticadas estratégias de manutenção de variedades tradicionais desenvolvidas nas diferentes regiões como alternativas à conservação.This study investigated the state of the art of traditional, or landrace seeds in the State of Rio Grande do Sul.

A model relating demographic, cultural, economical and institutional antecedents to entrepreneurship rate and to economic and social regional performance is proposed and tested using Rio Grande do Sul municipal data. The results support the view that institutional, economical and demographic variables shape entrepreneurship rate. Moreover support was also found for the fact that the entrepreneurship rate impacts the development of localities. Unlike other researches our results also suggest that the entrepreneurship rate mediates the effects of other variables on the regional economic and social performance. This result has important implications for establishing regional development policies because if the interest is to enhance economic and social development the best practice is to improve the entrepreneurship antecedents rather than only stimulate more people to start new business.Este artigo trata das relações entre a taxa de empreendedorismo, seus determinantes e consequências.

    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. Direções de magnetização características com polaridades normal e reversa foram obtidas após desmagnetizações térmicas e por campos magnéticos alternados. Do total de sítios amostrados 13 apresentaram polaridade reversa e 5, polaridade normal, compondo uma coluna magnetoestratigráfica onde se identificam três horizontes de polaridade, na ordem, reverso-normal-reverso. O pólo paleomagnético baseado em 18 sítios está localizado a 114.7ºE, 78.5ºS (dp = 8.1º; dm = 1.2º, depois de restaurada a paleohorizontal dos sítios de amostragem. Este pólo paleomagnético indica idade do Jurássico Superior-Cretáceo Inferior para a Formação Botucatu na área estudada, e indica que as paleolatitudes ocupadas eram da ordem de 21ºS.

Dois bovinos criados extensivamente que apresentavam emagrecimento progressivo e diarreia crônica foram necropsiados. Os linfonodos mesentéricos estavam aumentados e edematosos. A mucosa do intestino estava espessada e enrugada com aspecto cerebroide principalmente na porção final do íleo, válvula íleo-cecal e ceco. Fragmentos dos órgãos foram fixados em formalina 10%, incluídos em parafina, cortados e corados pela técnica de hematoxilina e eosina (HE e Ziehl-Neelsen (ZN. Fezes foram encaminhadas ao Departamento de Medicina Veterinária, Área de Medicina Veterinária Preventiva da Universidade Federal Rural de Pernambuco para o cultivo de Mycobacterium aviumsubsp.paratuberculosis em meio Lowenstein Jensen com micobactina e para realização da PCR. Histologicamente, havia enterite granulomatosa no jejuno, íleo, ceco e reto, afetando multifocalmente, também, o duodeno e o cólon. Havia, ainda, linfangite e adenite granulomatosa. Pela coloração de ZN foram observados numerosos bacilos álcool-ácido resistentes (BAAR no interior de macrófagos, células gigantes de Langhans e nos linfonodos mesentéricos no jejuno, íleo ceco e reto. Não houve crescimento bacteriano nas amostras de fezes e cinco amostras amplificaram a sequência genética IS900 específica do Mycobacterium aviumsubesp. paratuberculosis. Pelo presente trabalho pode-se concluir que a paratuberculose apesar dos poucos relatos ocorre também em bovinos de corte criados extensivamente no sul do Rio Grande do Sul e pode ter uma prevalência maior do que se supõe na região. Alerta-se para a necessidade do diagnóstico e da tomada de medidas efetivas de controle para esta doença que, por muitos, ainda é considerada uma doença exótica no Brasil.

    As continental rifting proceeds, the accommodation of lithospheric thinning by mechanical extension and magmatic intrusion represents an important but poorly constrained tectonic process. Insight into role of the magmatic component may come from the composition of volcanic products, which can record magma-lithosphere interactions. The volcanic activity in continental rift environments is frequently characterized by bimodal associations of mafic and silicic volcanism with heterogenous lithospheric contributions. We present a new integrated data set from several mafic volcanic fields in the Rio Grande Rift, consisting of major and trace element compositions, as well as isotopes. This data set provides insight into asthenospheric melting processes and interactions with the overlying lithosphere. The melting processes and the related extensional volcanism is the result of foundering of the Farallon slab. Large volume silicic eruptions such as those in the Sierra Madre Occidental originate from a large contribution of lithospheric melting, with a subordinate asthenospheric contribution. In contrast, Late Tertiary and Quaternary basaltic volcanic fields in the Rio Grande Rift were likely sourced in the asthenosphere and did not reside in the lithosphere for substantial periods. As a result the region is the ideal natural laboratory to investigate the interaction of asthenospheric melts with the lithosphere. In particular the wide array of volcanic fields contain multiple xenolith localities, such as Kilbourne Hole, providing direct samples of lithosphere and crust. Although previous studies have focused on correlations between amount of extension related to Farallon slab foundering, volcanic compositions, and their mantle sources, we present data that suggest that some compositional signatures may pre-date current tectonic processes. Radiogenic isotope data from several volcanic fields in New Mexico show a converging pattern in Pb isotope compositions, focusing on the

    Full Text Available Descrevem-se os aspectos epidemiológicos, sinais clínicos e a patologia de um surto de criptosporidiose em bezerros na região Sul do Rio Grande do Sul. De um lote de 400 bezerros de 30-45 dias de idade, 35 adoeceram e 16 morreram. Os bezerros nasciam fracos e logo após o nascimento apresentavam diarreia amarela, emagrecimento progressivo, desidratação, depressão e morte entre 10 e 15 dias após o início dos sinais clínicos. Na necropsia havia congestão dos vasos sanguíneos intestinais e mesentéricos. Havia distensão intestinal por gás e dilatação de vasos linfáticos. Microscopicamente havia achatamento das vilosidades intestinais, com necrose e atrofia. Aderidas à superfície das células epiteliais das vilosidades, havia estruturas puntiformes basofílicas de 2-5µm de diâmetro compatíveis com Cryptosporidium spp. A microscopia eletrônica revelou a presença de diferentes estágios do agente aderidos às microvilosidades de enterócitos. Alerta-se para a importância da criptosporidiose como agente primário de diarreia em bezerros. São necessárias medidas preventivas no que se refere ao manejo para diminuir as perdas econômicas e a contaminação ambiental, e, ainda, diminuir o risco para a saúde pública.

    The Culicidae composition of the Barra Grande Lake situated between the municipalities of Esmeralda (Rio Grande do Sul State) and Anita Garibaldi (Santa Catarina State) was assessed by monthly samplings. Twenty-four species were identified from a total of 1,185 specimens (74.7% as adults and 25.3% as immatures), with Aedes fluviatilis Lutz as the most frequent species. Several species are new records, and some of them are of public health interest. It is suggested that local environmental changes may alter the relationship between humans and vector mosquitoes.

    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

    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.

    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.

    Treatment of phenylketonuria (PKU) includes the use of a metabolic formula which should be provided free of charge by the Unified Health System (SUS). This retrospective, observational study sought to characterize judicial channels to obtain PKU treatment in Rio Grande do Sul (RS), Brazil. Lawsuits filed between 2001- 2010 and having as beneficiaries PKU patients requesting treatment for the disease were included. Of 20 lawsuits filed, corresponding to 16.8% of RS patients with PKU, 19 were retrieved for analysis. Of these, only two sought to obtain therapies other than metabolic formula. In all the other 17 cases, prior treatment requests had been granted by the State Department of Health. Defendants included the State (n = 19), the Union (n = 1), and municipalities (n = 4). In 18/19 cases, the courts ruled in favor of the plaintiffs. Violation of the right to health and discontinuation of State-provided treatment were the main reasons for judicial recourse. Unlike other genetic diseases, patients with PKU seek legal remedy to obtain a product already covered by the national pharmaceutical assistance policy, suggesting that management failures are a driving factor for judicialization in Brazil.

    Full Text Available The objective in this research was to investigate if, statistically, there are performance financial and socioeconomic performance differences between emancipated cities in Rio Grande do Sul and their respective cities of origin. The adjusted population consists of 66 cities, 25 of which were emancipated and 41 cities of origin. The cities’ performance is analyzed by comparing the indicators from the year before the emancipation date with the post-emancipation indicators. The indicators and selected variables were collected in the databases of the STN, FEE/RS and IBGE. Based on the global analysis, the research findings suggest that the emancipated cities’ performance does not significantly differ from the cities of origin. On the other hand, based on the individual analysis per city and indicator, it is concerning that 92% of the emancipated cities show a negative own income, reflecting a strong dependence on the resources transferred by the state and the Union. The indicators related to spending on education, health, culture, sanitation, housing and urbanization are lower in the emancipated cities. The same is true for the other financial and socioeconomic indicators.

    Full Text Available The study of the Rio Grande/Bravo (RGB Basin water allocation demonstrates how the United States (U.S. and Mexico have consolidated a transboundary framework based on water sharing. However, the water supply no longer meets the ever-increasing demand for water or the expectations of different stakeholders. This paper explores opportunities for an enhanced management regime that will address past problems and better examine how to balance demands for a precious resource and environmental needs. Based on an overview of the RGB Basin context and the water allocation framework, as well as a discussion on stakeholders’ ability to achieve solutions, this paper explores three key questions: (1 Does the current binational water allocation framework meet current and future human and environmental needs? (2 How can the U.S.-Mexico water allocation framework be adapted to balance social and environmental water demands so it can support and preserve the RGB Basin ecosystem? (3 What are the main opportunities to be explored for expanding the U.S.-Mexico water resources allocation framework? The U.S.-Mexico water resources framework is subject to broad interpretation and may be adapted to the circumstances taking the fullest advantage of its flexibility. Policy recommendations highlight the existing flexibility of the binational framework, the potential to move forward with an ad hoc institutional arrangement, and the creation of political will to achieve change through stakeholders recommendations.

    The primary objective of this work is to synthesize components of benthic flux in the Patos Lagoon coastal zone, Rio Grande do Sul, Brazil. Specifically, the component of benthic discharge flux forced by the terrestrial hydraulic gradient is 0.8 m3 d-1; components of benthic discharge and recharge flux associated with the groundwater tidal prism are both 2.1 m3 d-1; components of benthic discharge and recharge flux forced by surface-gravity wave setup are both 6.3 m3 d-1; the component of benthic discharge flux that transports radium-228 is 350 m3 d-1; and components of benthic discharge and recharge flux forced by surface-gravity waves propagating over a porous medium are both 1400 m3 d-1. (All models are normalized per meter shoreline.) Benthic flux is a function of components forced by individual mechanisms and nonlinear interactions that exist between components. Constructive and destructive interference may enhance or diminish the contribution of benthic flux components. It may not be possible to model benthic flux by summing component magnitudes. Geochemical tracer techniques may not accurately model benthic discharge flux or submarine groundwater discharge (SGD). A conceptual model provides a framework on which to quantitatively characterize benthic discharge flux and SGD with a multifaceted approach.

    Full Text Available The dissemination of computer use and software development brought about intense modifications in accounting firms’ procedures as from the 1990’s. From the perspective of accounting professionals, the impact of these innovations has not been properly analyzed. Therefore, the general objective in this study is to assess the impacts technological innovation has caused in the accounting firms in Rio Grande do Sul as from 1990. From the methodological viewpoint, the research is exploratory and the data were collected through a survey, using a structured questionnaire with a scale from zero to ten. The non-probabilistic sample included 408 respondents and the analyses based on these questionnaires took place using “R” factor analysis. Among the results, the respondents’ perception that the technological innovation permitted more agile service provision is highlighted, as well as better information quality and the provision of more useful information to the managers. The element that most influenced the firms was the arrival of the Internet. Nevertheless, these innovations enhanced the complexity of the firms’ tasks and the need to capture the employees.

    Paracoccidioides brasiliensis is a dimorphic fungus and major cause of paracoccidioidomycosis (PCM), which is a systemic and endemic mycosis in Brazil. In Southern Brazil, an increased number of cases were detected since the 1990 s. Therefore, in order to determine areas with the presence of the fungus, this study aimed to investigate infection by P. brasiliensis in dogs from Southern Brazil. Indirect ELISA was used to detect antibodies against P. brasiliensis gp43. One hundred and ninety-six stray and semi-domiciled dogs from the municipalities of Pelotas and Capão do Leão, Rio Grande do Sul were included in this study. P. brasiliensis infection was detected in 58 animals (29.6%) with no significant difference for gender, age and breed. Seropositive animals were detected in all neighborhoods in the city of Pelotas as well as in the neighboring municipality Capão do Leão. The detection of antibodies against gp43 in dogs suggests the presence and wide distribution of the fungus in Pelotas and Capão do Leão, warning for the possibility of PCM disease in dogs as well as in humans from this region.

    Full Text Available Fibropapillomatosis (FP is a benign tumoral disease that affects sea turtles, hampering movement, sight and feeding, ultimately leading to death. In Brazil, the disease was described for the first time in 1986. Research suggests the involvement of a herpesvirus in association with environmental and genetic factors as causal agents of FP. The objective of the present study was to detect and characterize this herpesvirus in sea turtles living in the coast of state Rio Grande do Sul (RS, Brazil. From October 2008 to July 2010, 14 turtles were observed between the beaches of Torres and Tavares, of which 11 were green turtles (Chelonia mydas and 3 were loggerhead turtles (Caretta caretta. All turtles were young and mean curved carapace length was 37.71±7.82cm, and varied from 31 to 55cm. Only one green turtle presented a 1cm, papillary, pigmented fibropapilloma. Skin and fibropapilloma samples were analyzed by conventional and real time PCR assays to detect and quantify herpesvirus. All skin samples were negative, though the fibropapilloma specimen was positive in both tests. Viral load was 9,917.04 copies of viral genome per milligram of tissue. The DNA fragment amplified from the fibropapilloma sample was sequenced and allocated in the Atlantic phylogeographic group.

    Full Text Available ABSTRACTThe genus Sinningia belongs to the Neotropical tribe Gesnerieae, subtribe Ligeriinae, presently consisting of only three genera, Paliavana, Sinnigiaand Vanhouttea. These genera were separated from a larger concept of tribe Gloxinieae based on phylogenetic studies with molecular data. In Rio Grande do Sul, southern Brazil, 12 species and one natural hybrid of Sinningiahave been recorded. Species of Sinningia in this area are erect or ascending herbs or subshrubs arising from underground or partially exposed tubers. They grow in very distinct ecological conditions, from water-saturated marshes to dry grasslands or shrublands, but most often in rupicolous or epiphytic habitats commonly associated with forest environments. In this review we provide an identification key to the species level and morphological descriptions and illustrations, comments on taxonomic aspects, distributional maps and IUCN Red List Categories and Criteria for all twelve species. Additionally, we designate lectotypes for S. allagophylla and S. sellovii and consider the recently described S. lutea as a synonym of the highly variable S. allagophylla.

    Full Text Available Using a combination of flower traps and visual observations, we surveyed three watermelon (Citrullus lanatus (Thunb. Matsum. & Nakai fields in the Lower Rio Grande Valley to determine what bees inhabit this crop in this region. 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.

    As the finite, and often over-allocated water resources of the western United States are challenged by growing demands, computer based simulations can provide a powerful tool for evaluating potential water use scenarios in support of hydrologic decision making and water policy analysis. To represent the complexities of water resource management, a model should capture the salient behaviors and interactions between, the groundwater, surface water, and human behavioral systems, while to effectively connect science to the decision process, the model should run quickly enough to allow real time evaluation of a wide range of scenarios by stakeholders and decision makers themselves. As these potentially mutually exclusive objectives are pursued, the tradeoffs between resolution, run time, and the degree of coupling between modeled systems must be considered. In the Upper Rio Grande in New Mexico, three MODFLOW based, distributed groundwater models of the Espanola, Albuquerque, and Socorro groundwater basins have been used to calibrate a spatially simplified representation of the groundwater system in the region. The groundwater model is dynamically coupled to surface water and human behavioral systems as part of an integrated system dynamics based model which runs quickly enough to support rapid basin scale water policy scenario evaluation. This presentation will focus on development of the simplified groundwater model, and the performance tradeoffs and gains associated with spatial aggregation and dynamic coupling to the surface water system.

    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.

    The increasing of ethanol production at Rio Grande do Sul, Brazil, will occur in small scale, through the microdistilleries installed at the present sugar cane producer regions, characterized by the small properties and familiar manpower. However, that production scale is lack of technical and cost analysis for allowing a better evaluation of the existent scenery at the State or Rio Grande do Sul, Brazil. From the production data of four microdistilleries installed at the Rio Grande do Sul, it is possible to affirm that the income obtained for the substract extraction and fermentation are reasonable (average 70.4 and 82.8, respectively). The distillation, however, posses a low yield (average 65.9%), resulting in a negative impact in the industrial productivity, on the energetic factor and the production cost. The increasing of yield of distillation for a satisfactory value (92.0 %) would result in a increasing of industrial productivity up to 61 % (Case B). So, it is necessary a more technical attention to that step for guarantee the development of the ethanol production activity in a small scale.

Understanding that the city went through three distinct stages: military, commercial and industrial, here is treated the transition from the second to the third stage. In this paper, we applied concepts of landscape’s archaeology and we considered the informative aspects (as recording technique and subjective expression of photography. It counts with supporting papers and reports of that time, and the analysis of 12 photographs, to perceive the transitions - changes social, economic, political and symbolic - materialized in city landscapes. In this way, we believe that the information intersection provides the perception of the elements that have changed.

    Full Text Available The environmental licensing is one of management tools established by the Environmental National Policy in Brazil that is being implemented in the scale of the municipalities in the State of Rio Grande do Sul, Brazil. The licensing, in this context, will only be possible if the municipalities meet the requirements demanded by the State’s Environmental Agency. One of them is the ecological and economical zoning (ZEE, a very difficult task to perform due to lack of technical personnel in the municipalities and the difficulty of integrating legal, inter institutional and scientific data to their realization. The Federal University of Rio Grande has drafted a proposal of ZEE to the 22 municipalities that together make up the southern part of the State of Rio Grande do Sul. After a technical meeting with professionals from various related subject areas, a methodology to be applied for the development of the proposal was defined. This includes the identification and characterization of basic territorial units with the aid of a Geographical Information System, for which shall be defined goals, guidelines, potential and usage restrictions, based on their vulnerabilities and/or environmental weaknesses. The regional mapping was presented at the scale of 1: 100,000 and should be used as a basis for further details on the municipal scale.

    The Rio Grande is the natural boundary between the United States and Mexico from El Paso, Texas, to Brownsville, Texas. It supports about 12 million people on both sides of the border for municipal, agricultural, industrial, and recreational uses. The rapid population and economic growth along the border region has led to increased pollution in the Rio Grande, which has been linked to several border health issues associated with pesticide contamination. This project was initiated to assess the organochlorine pesticide levels in the water and sediments in Manadas Creek, an urban tributary of the Rio Grande located in north Laredo, Texas. Water and sediment samples were collected monthly during a 6-month period from July to December of 2006 and analyzed using gas chromatography with an electron capture detector after extraction via a solid-phase microextraction technique. Among the water and sediment samples collected, several organochlorine pesticides including alpha-, beta-, and gamma-hexachlorocyclohexane (HCH), heptachlor epoxide, endrin, and 4,4'-DDT were found in either the creek water or sediments. Analysis of variance results indicated that only gamma-HCH had significant variation in the creek water among the sampling periods. Comparison of results with previous findings showed the presence of higher levels of HCH isomers and much lower DDT concentrations in the present study.

    Full Text Available São descritos vinte e quatro surtos de tétano ocorridos no ano 2009 em bovinos de corte em propriedades situadas na região de influência do Laboratório Regional de Diagnóstico (LRD, sul do Rio Grande de Sul. 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.

    Full Text Available Os estudos sobre carreira têm se mostrado relevantes na área de gestão de pessoas, entretanto, a maioria das pesquisas relativas ao tema é voltada a gerentes e diretores de grandes corporações.  Este artigo, por sua vez, tem como objetivo conhecer a percepção sobre carreira de funcionários das áreas administrativa e de produção de uma empresa automotiva situada na região metropolitana de Porto Alegre, Rio Grande do Sul. Esta pesquisa, com abordagem qualitativa, caracteriza-se como um estudo de caso de natureza exploratório-descritiva. O quadro teórico utilizado contempla o contexto histórico das teorias de carreira, suas concepções e significados e sua gestão. Para obtenção dos dados, utilizaram-se entrevistas semiestruturadas, realizadas com doze funcionários. A escolha dos respondentes considerou que eles não ocupassem cargos de gerência ou direção na organização, bem como seu nível de escolaridade. Os dados obtidos foram analisados quanto ao conteúdo e revelaram que a maioria dos entrevistados entende carreira como sinônimo de evolução ou ascensão profissional. Esses funcionários, de níveis hierárquicos inferiores, relacionam sua permanência na organização ao oferecimento de possibilidades de satisfação pessoal, crescimento e motivação profissional.

    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

    1988-01-01

    One hundred twenty-three of 300 blood samples (41%) taken from Rio Grande wild turkeys (Meleagris gallopavo intermedia) from three locations in southern Texas (Welder Wildlife Refuge, Chaparrosa Ranch, and Campo Alegre Ranch) and subinoculated into domestic broad-breasted white turkey poults were positive for a Plasmodium (Novyella) sp. Analysis of blood films from 350 turkeys revealed Haemoproteus meleagridis in 76% of the birds. A significantly greater mean parasite intensity was observed in birds from Welder Wildlife Refuge. Birds from the Campo Alegre Ranch exhibited a significantly higher prevalence of H. meleagridis than birds from Chaparrosa. The Plasmodium sp. was infective for canaries (Serinus canaria), bobwhites (Colinus virginianus), and ring-necked pheasants (Phasianus colchicus), but would not produce infection in white leghorn chickens (Gallus gallus) or Coturnix quail (Coturnix coturnix). Attempts to infect Culex tarsalis and C. pipiens pipiens were unsuccessful. Asexual erythrocytic synchrony was not observed when blood-induced infections were monitored in two domestic turkey poults every 4 hr for 72 hr. Exoerythrocytic stages were not found upon examination of impression smears and tissue samples taken from brain, liver, spleen, kidney, lung, and bone marrow. The Plasmodium sp. is most similar morphologically to three species in the subgenus Novyella, P. hexamerium, P. vaughani, and P. kempi. The most striking similarities are to P. hexamerium, and involve mean merozoite number, erythrocytic schizont location, and vertebrate host susceptibility. It differs from P. vaughani in being able to infect turkeys and in type of parasitized erythrocytes. Differences to P. kempi include mean merozoite number, and ability to infect pheasants, and its inability to develop inC. pipiens and C. tarsalis.

    ABSTRACT OBJECTIVE This study aims to verify the adequacy profile of the cities of the State of Rio Grande do Sul, Brazil, in relation to the purchase of products of family farming by the Programa Nacional de Alimentação Escolar (PNAE - National Program of School Meals). METHODS This is a quantitative descriptive study, with secondary data analysis (public calls-to-bid). The sample consisted of approximately 10% (n = 52) of the cities in the State, establishing a representation by mesoregion and size of the population. We have assessed the percentage of food purchased from family farming, as well as the type of product, requirements of frequency, delivery points, and presence of prices in 114 notices of public calls-to-bid, in 2013. RESULTS Of the cities analyzed, 71.2% (n = 37) reached 30% of food purchased from family farming. Most public calls-to-bid demanded both products of plant (90.4%; n = 103) and animal origin (79.8%; n = 91). Regarding the degree of processing, fresh products appeared in 92.1% (n = 105) of the public calls-to-bid. In relation to the delivery of products, centralized (49.1%; n = 56) and weekly deliveries (47.4%; n = 54) were the most described. Only 60% (n = 68) of the public calls-to-bid contained the price of products. CONCLUSIONS Most of the cities analyzed have fulfilled what is determined by the legislation of the PNAE. We have found in the public calls-to-bid a wide variety of food, both of plant and animal origin, and most of it is fresh. In relation to the delivery of the products, the centralized and weekly options prevailed. PMID:28225910

    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.

    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.

    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 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.

  14. Configuration and Correlation of Fluvial Terrace Deposits In the Lower Rio Salado Valley: A Record of Magmatic Uplift and Active Normal Faulting in the Rio Grande Rift

    The Rio Salado is a western tributary of the Rio Grande whose valley is flanked by six major terrace levels. The Rio crosses several active rift-related normal faults and the active, mid-crustal Socorro Magma Body (SMB; a sill at 19 km depth that is actively doming the land surface), providing an unusual opportunity to explore the effects of deep magma emplacement and active faulting on the terraces. Rio Salado terraces were mapped using a high-resolution DEM and digital color stereophotographs and were projected onto a valley-parallel vertical plane to construct longitudinal profiles. Three new soil pits were described to aid terrace correlation. A net incision rate of 0.41 ± 0.06 m/ka was inferred from the correlation of a major fill-cut terrace to the 122 ± 18 ka Airport surface ~25 km south of the Rio Salado. This incision rate is >1.5 times more rapid than estimated rates nearby or in other parts of New Mexico, but yields age estimates for other terraces that are consistent with soil development. Terrace gradients in the Rio Salado have increased through time, indicating either stream response to Rio Grande incision or footwall tilting from the Quaternary Loma Blanca fault (LBF). Two terraces in the LBF hanging wall are back-tilted relative to their footwall counterparts, suggesting a listric geometry for the LBF. However, two others (Qtf and Qtc) are east-tilted relative to their footwall counterparts. Both Qtf and Qtc merge eastward with the next youngest terrace in the flight, and Qtc is arched, consistent with an earlier episode of surface uplift above the SMB. Future work will involve (a) additional terrace mapping over the SMB, (b) cosmogenic 36Cl depth profile dating of the Rio Salado terraces to determine incision rates, allow regional terrace correlations, and constrain fault-slip slip rates and the record of SMB-related surface uplift, and (c) numerical modeling of SMB inflation constrained by uplift signals.

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.

    1986-05-01

    Apatite fission track ages for samples collected from three mountain ranges on the eastern margin of the Rio Grande rift are used to examine the late Cretaceous to middle Miocene uplift and erosional history of north central New Mexico. The dates indicate that uplift and erosion was in progress in the Sandia Mountains near Albuquerque and in the Taos Range portion of the Sangre de Cristo Mountains near Taos at least 30-35 m.y. ago. Uplift and erosion continued in the Sandia Mountains at a relatively constant rate (81 m/m.y.) until 15 Ma; the rate of uplift and erosion in this area has approximately tripled in the past 15 m.y. (230 m/m.y.). Igneous activity in the Taos Range has largely obscured the early Tertiary uplift and erosional history of this portion of the Sangre de Cristo Mountains. A fission track date from one of the middle Tertiary intrusions in the Taos Range is used to calculate the cooling rate due to uplift and erosion in this area for the past 14 m.y. (210 m/m.y.). The uplift and erosion rates derived from the fission track data for the past 14-15 m.y. are similar to those obtained from other geological evidence. In contrast to the Oligocene to Miocene ages found in the other two areas, the apatite fission track ages from the Santa Fe Range portion of the Sangre de Cristo Mountains near Santa Fe are Late Cretaceous to early Eocene. These dates record the cooling of the area due to uplift and erosion during the Laramide event. The preservation of these older ages indicates that the Santa Fe Range was a low-lying area during the Oligocene to Miocene, while the surrounding areas (Sandia Mountains and Taos Range) underwent uplift and erosion. Volcanic activity occurred in the vicinity of the two areas of positive relief. Localized crustal extension associated with the volcanism may have contributed, in part, to the uplift of these areas. Using simple, two-dimensional thermal models, we found that the apparent denudation rates derived from the fission

  12. Implementation of MAR within the Rio Grande Basin of Central New Mexico, USA

    2014-05-01

    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 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

    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.

  19. From Channel to Floodplain: Geomorphic Transformation of the Rio Grande in the Big Bend Region of Texas, Chihuahua, and Coahuila

    Multiple analyses indicate that over the last 17 years on the Rio Grande in Big Bend National Park, a positive feedback mechanism existed between extended base-flows, non-native vegetation invasion, and vertical floodplain accretion which caused rapid channel narrowing and disconnection of the floodplain from the channel. We identified this feedback mechanism using detailed stratigraphic analyses of inset floodplain deposits, dendro-geomorphological analyses of woody vegetation removed from floodplain trenches, hydrologic analyses, and observed shifts in the stage-discharge relation. The active channel width of the Rio Grande has narrowed by 35-50% since 1991. Narrowing has occurred by vertical accretion of fine-grained deposits on top of alternate bars of sand, gravel, and cobbles. These vertically accreting deposits are inset within natural levees. In two long floodplain trenches, we measured 2.75 and 3.5m of vertical accretion, all of which occurred during the past 17 years. In some localities, nearly 90% of bare, active channel bars were converted to vegetated floodplain during the same period. Channel narrowing by vertical accretion coincided with a rapid invasion of non-native riparian vegetation (Tamarix spp., Arundo donax) which increased bank roughness and created a positive feedback of decreased channel capacity, an upward shift of the stage-discharge relation, overbank flooding at lower discharges, and continued vertical accretion. Thus, although peak flows were reduced by 48% and the percent exceedance of both the two-year flood and long- term mean annual flow declined during the past 17 years, overbank flooding continued. These changes reflect a shift in the geomorphic character of the Rio Grande from a wide river with transient channel margins and in-stream geomorphic features to a simple channel with steep, definable, vegetated banks and few bare active geomorphic surfaces.

    A 405 cm long core was drilled in the Aparados da Serra National Park (Rio Grande do Sul, Brazil) at the end of 1999, and in all, 23 samples were taken for palynological investigation. The cores′ age is estimated at 27 000 a BP based on three radiocarbon dates taken from different depths of the core. Palynological methods were used to reconglacial conditions mainly influenced by the South Pole throughout several transition stages to today's humid warm climate, mainly being influenced by the Brazil stream.

    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.

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.

    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.

    This study characterized the thermal regime in a number of Colorado and New Mexico streams that contain populations of Rio Grande cutthroat trout (Oncorhynchus clarkii virginalis) and had no previous record of continual temperature records. When compared to Colorado’s water temperature criteria (Cold Tier 1), a portion of these populations appeared to be at risk from elevated stream temperatures, as indicated by exceedance of both acute (17–22 percent) and chronic (2–9 percent) water quality metrics. Summer water temperature profiles recorded at sites within current Rio Grande cutthroat trout habitat indicated that although the majority of currently occupied conservation streams have temperatures that fall well below these biologically based acute and chronic thermal thresholds, several sites may be at or approaching water temperatures considered stressful to cutthroat trout. Further, water temperatures should be considered in decisions regarding the current and future thermal suitability of potential Rio Grande cutthroat trout restoration sites. Additionally, baseflow discharge sampling indicated that a majority of the sampled stream segments containing Rio Grande cutthroat trout have flows less than 1.0 cubic feet per second (cfs) in both 2010 (74 percent) and 2011 (77 percent). The relative drought sensitivity of these low baseflow streams containing Rio Grande cutthroat trout could be further evaluated to assess their probable sustainability under possible future drought conditions.

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

    The western yellow-billed cuckoo (Coccyzus americanus occidentalis) is a Distinct Population Segment that has been proposed for listing under the Endangered Species Act, yet very little is known about its spatial use on the breeding grounds. We implemented a study, using radio telemetry, of home range and use of habitat for breeding cuckoos along the Middle Rio Grande in central New Mexico in 2007 and 2008. Nine of 13 cuckoos were tracked for sufficient time to generate estimates of home range. Overall size of home ranges for the 2 years was 91 ha for a minimum-convex-polygon estimate and 62 ha for a 95%-kernel-home-range estimate. Home ranges varied considerably among individuals, highlighting variability in spatial use by cuckoos. Additionally, use of habitat differed between core areas and overall home ranges, but the differences were nonsignificant. Home ranges calculated for western yellow-billed cuckoos on the Middle Rio Grande are larger than those in other southwestern riparian areas. Based on calculated home ranges and availability of riparian habitat in the study area, we estimate that the study area is capable of supporting 82-99 nonoverlapping home ranges of cuckoos. Spatial data from this study should contribute to the understanding of the requirements of area and habitat of this species for management of resources and help facilitate recovery if a listing occurs.

    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.

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.

    Approximately two-thirds of the runoff in the Rio Grande begins as seasonal snowpack in the headwaters above the USGS stream gaging stations at several points (nodes) above Albuquerque, New Mexico. Resource managers in the Rio Grande Basin rely on accurate short and long term forecasts of water availability and flow at these nodes to make important decisions aimed at achieving a balance among many different and competing water uses such as municipal, fish and wildlife, agricultural, and water quality. In this study, a distributed, physically based hydrologic model is used to investigate the degree of spatial and temporal distribution of snow and the processes that control snowmelt necessary to accurately simulate streamflow at seven of these nodes. Specifically, snow distribution and surface runoff are estimated using a combination of the USGS Modular Modeling System (MMS), GIS Weasel, Precipitation-Runoff Modeling System (PRMS), and XYZ snow distribution model. This highly collaborative work between researchers at the Desert Research Institute and the USGS is an important part of SAHRA (Sustainability of semi-Arid Hydrology and Riparian Areas) efforts aimed at improving models of snow distribution and snowmelt processes.

    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.

    This article seeks to describe the utilization and coverage percentage of the Nutritional and Food Surveillance System (SISVAN-Web) in the Regional Health Offices of Rio Grande do Sul in 2010 and to assess its correlation with socio-economic, demographic and health system organization variables at the time. It is an ecological study that used secondary data from the SISVAN-Web, the Department of Primary Health Care, the IT Department of the Unified Health System and the Brazilian Institute of Geography and Statistics. The evaluation of utilization and coverage data was restricted to nutritional status. The percentage of utilization of SISVAN-Web refers to the number of cities that fed the system. Total coverage was defined as the percentage of individuals in all stages of the life cycle monitored by SISVAN-Web. It was found that 324 cities fed the application, corresponding to a utilization percentage of 65.3%. Greater system coverage was observed in all Regional Health Coordination (RHC) Units for ages 0 to 5 years and 5-10 years. There was a significant association between the percentage of utilization of SISVAN-Web and Family Health Strategy coverage in each RHC Unit. The results of this study indicated low percentages of utilization and coverage of SISVAN-Web in Rio Grande do Sul.

    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.

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.

  16. 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 2015 seepage investigation was conducted on February 10, 2015, during the low-flow conditions of the non-irrigation season. During the 2015 investigation, discharge was measured at 23 sites along the main-stem Rio Grande and 19 inflow sites within the study reach. Because of extended drought conditions affecting the basin, many sites along the Rio Grande (17 main-stem and 10 inflow) were observed to be dry in February 2015.

    Full Text Available Resumo Satisfação no Trabalho pode ser entendida como o vínculo afetivo do indivíduo com seu ambiente laboral. A profissão de policial militar é considerada de alto risco, pois ele lida constantemente com a violência, a brutalidade e a morte. Frente a este contexto, esse estudo foi desenvolvido visando identificar o grau de Satisfação no Trabalho dos policiais militares do Rio Grande do Sul. Realizou-se uma pesquisa descritiva, do tipo survey, com abordagem quantitativa. Os participantes do estudo totalizaram 519 policiais militares pertencentes a quartéis de cidades localizadas no estado do Rio Grande do Sul. A Escala de Satisfação no Trabalho (EST foi utilizada como instrumento de pesquisa. No geral, identificou-se que os policiais tendem a sinalizar insatisfação em relação ao trabalho. Dentre as dimensões que compõe a EST, tendem a sinalizar insatisfação em relação ao salário (média: 2,79 e com as promoções (média: 3,03; indiferença (nem satisfeitos e nem insatisfeitos em relação à chefia (média: 4,42 e à natureza do trabalho (média: 4,37; e, por fim, sinalizam tendência à satisfação em relação aos colegas (média: 5,00. Espera-se com essas evidências contribuir para as futuras decisões organizacionais que impliquem na saúde dos policiais militares e consequente qualidade de vida, da equipe e seus familiares.

    Full Text Available Tuberculose é uma doença cujo tratamento é complexo e demorado implicando em altas taxas de abandono. O abandono leva à continuidade das taxas de transmissão, ao aumento da morbi-mortalidade e da resistência microbiana. Santa Cruz do Sul é considerado um dos 15 municípios prioritários no Rio Grande do Sul para o controle da tuberculose devido às altas taxas de abandono, baixos índicesde cura e elevado número de casos. Dessa forma, o objetivo do estudo foi descrever o perfi l epidemiológico dos pacientes que abandonaram o tratamento para tuberculose no município de Santa Cruz do Sul no período de janeiro de 2000 a dezembro de 2010. Método: Realizou-se um estudo descritivo retrospectivo. Os dados foram coletados nos prontuários dos pacientes no ambulatório de tuberculose e nas fi chas do Sistema de Notifi cação de Agravos de Notifi cação (Sinan. Os dados foram tabulados e analisados em SPSS 18.0. Análises estatísticas descritivas foram realizadas. Resultados: A taxa de abandono observada neste estudo foi de 11,1%. A média de idade dos pacientes que abandonaram o tratamento foi de 37,2 anos, 80,4% eramhomens, 27,5% eram alcoolistas e 14,3% tinham AIDS. Conclusão: Verifi cou-se um elevado percentual de casos de abandono no município. O abandono foi signifi cativamente maior entre os homens. Outras variáveis associadas ao abandono não foram identifi cadas nesta população provavelmente devido à falta de informações descritas nas fontes de pesquisa. No entanto a melhoria no preenchimento dos dados nos prontuários permitirá futuramente conhecer o real perfil epidemiológico destes pacientes. Além disso, a inserção de um tratamento diretamente observado e a capacitação dos agentes comunitários de saúde são ações essenciais a serem implementadas no município no intuito de reduzir as taxas de abandono.

Embora a delimitação espacial esteja circunscrita ao estado do Rio Grande do Sul, não deixaremos de levar em consideração a articulação entre a política e a economia regional com o governo de Juscelino Kubitschek e seu modelo de desenvolvimento para o país. Como marco temporal é utilizado o ano de 1958 - onde se desenrolam a campanha e as eleições - e os dois primeiros anos do governo Brizola (1959 e 1960. A pesquisa justifica-se pela necessidade de se aprofundar a análise de aspectos ainda pouco explorados pela historiografia, que tem privilegiado, no que diz respeito a este governo, basicamente os temas relacionados à reforma agrária, às encampações, à educação e ao movimento da Legalidade. Assim, pretendemos analisar o debate sobre quais os modelos de industrialização estavam sendo propostos pelas duas principais alianças políticas (PTB-PRP-PSP e Frente Democrática durante a campanha, bem como a orientação do governo do estado após Leonel Brizola ser eleito. Assim, buscaremos compreender o papel da grande imprensa gaúcha nos debates referidos. O período é caracterizado pela forte ideologização das questões referentes ao desenvolvimento do país e carece de um trabalho que faça a análise no contexto regional

    The six Middle Rio Grande Pueblos have prior and paramount rights to deliveries of water from the Rio Grande for their use. When the pueblos or the Bureau of Indian Affairs Designated Engineer identifies a need for additional flow on the Rio Grande, the Designated Engineer is tasked with deciding the timing and amount of releases of prior and paramount water from storage at El Vado Reservoir to meet the needs of the pueblos. Over the last three decades, numerous models have been developed by Federal, State, and local agencies in New Mexico to simulate, understand, and (or) manage flows in the Middle Rio Grande upstream from Elephant Butte Reservoir. In 2008, the Coalition of Six Middle Rio Grande Basin Pueblos entered into a cooperative agreement with the U.S. Geological Survey to conduct a comprehensive survey of these hydrologic models and their capacity to quantify and track various components of flow. The survey of hydrologic models provided in this report will help water-resource managers at the pueblos, as well as the Designated Engineer, make informed water-resource-management decisions that affect the prior and paramount water use. Analysis of 4 publicly available surface-water models and 13 publicly available groundwater models shows that, although elements from many models can be helpful in tracking flow in the Rio Grande, numerous data gaps and modeling needs indicate that accurate, consistent, and timely tracking of flow on the Rio Grande could be improved. Deficient or poorly constrained hydrologic variables are sources of uncertainty in hydrologic models that can be reduced with the acquisition of more refined data. Data gaps need to be filled to allow hydrologic models to be run on a real-time basis and thus ensure predictable water deliveries to meet needs for irrigation, domestic, stock, and other water uses. Timeliness of flow-data reporting is necessary to facilitate real-time model simulation, but even daily data are sometimes difficult to

  15. 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

    This work examines the indicators of wealth and its relations with the electricity demand for the State of Rio Grande do Sul, with a trend scenario and alternative scenarios for the electricity demand for the period 2008-2030. A capacity model was developed in order to estimate the increase of the installed capacity necessary to supply the foreseen demand. This model considers new additions of the power plants in implantation, planned and in study, from a base of information and data of the Ministry of Energy. Based on the comparison of the scenarios established with the developed model, are identified strangulations of power supply in the considered time for two of them, the participation of the primary sources capable to prevent them is explored and the total investment for realization of developed model and one established scenario that show strangulation, through hydroelectric plants, thermoelectric based on mineral coal and thermoelectric based on natural gas.

    The aim of this study to analyze the properties of ceramic blocks produced by the states of Paraiba and Rio Grande do Norte. For this, the raw materials used in the fabrication of these blocks were characterized using the techniques of chemical, granulometry and mineralogical analysis and determination of the plasticity index of mixture ceramic. The properties of the ceramic blocks were determined by evaluating the geometric and visual characteristics and determining the water absorption and compressive strength, according to technical recommendations ABNT NBR 15270. It can be observed that samples have chemical compositions with a predominance of SiO{sub 2} and Al{sub 2}O{sub 3} and Fe{sub 2}O{sub 3} and they are composed of mica, kaolinite, quartz, feldspar and goethite. It was also noted that all blocks showed compressive strength less than 1.5 MPa. (author)

    In this work we study three clays of the state of Rio Grande do Norte, Brazil, to evaluate the potential them when subjected to high rates of heating. The samples were formed by pressing and subject to rates of 5 deg C / min, 10 deg C / min and 15 deg C / min, with temperature of 950 deg C. This study determined the technological properties of the samples. The mineralogical composition was identified by X-ray diffraction. The chemical composition was determined by Xray fluorescence. The Atterberg limits, were used to classify the samples on the plasticity. Were also performed: dilatometry, size analysis and scanning electron microscopy. The examination of the processing variables and the intrinsic characteristics of each material indicates that the RX clay showed the best results for the manufacture of blocks and tiles. The techniques used in this study were efficient and the initial objectives were achieved. (author)

    Full Text Available A new genus and species of glandulocaudine, Lophiobrycon weitzmani, is described based on specimens collected in headwater tributary streams of the rio Grande, upper rio Paraná system, State of Minas Gerais, southeastern Brazil. The inclusion of the new species in the phylogeny of the subfamily Glandulocaudinae proposed by Weitzman & Menezes (1998, reveals a sister group relationship between the new genus and the monophyletic group composed of Glandulocauda and Mimagoniates that currently form the tribe Glandulocaudini. The new species can be readily distinguished from all other species of the tribe by the autapomorphic presence in adult male individuals (with more than 23.9 mm standard length of an adipose-fin whose base extends for almost the entire distance between the posterior terminus of the base of the dorsal fin and the base of the upper lobe of the caudal fin and averages approximately 25% standard length, along with the presence of globular expansions formed by the lepidotrichia and hypertrophied soft tissue in the middle portions of the first and second pectoral-fin rays. The diagnosis of the tribe Glandulocaudini is modified to accommodate the new genus.

    Full Text Available Atrazine and oxamyl are commonly-used pesticides in the Lower Rio Grande Valley of South Texas. Problem statement: Pesticides may become environmental contaminants due to overuse, runoff and other mechanisms and may impact non-target organisms and ecosystems. Pesticides may be degraded by indigenous microorganisms or by abiotic means. In this study, waterborne bacteria from agricultural canals were examined to assess potential atrazine and oxamyl degradation in the Lower Rio Grande Valley. Approach: Water samples were collected March 2007 and June 2009 and inoculated onto agar media containing either atrazine or oxamyl to estimate densities of atrazine-tolerant and oxamyl-tolerant bacteria. Bacterial isolates were characterized morphologically by visually observing colony shape and size and by gram-staining. Commercial test strips and microplates were used to differentiate biochemical and nutritional capabilities of bacteria and an inhibition disk assay was employed to determine pesticide sensitivity. Results: Average density of atrazine-tolerant bacteria was 2,233 cfu mL-1 in March 2007 and 12, 845 cfu mL-1 in June 2009. Average density of oxamyl-tolerant bacteria was 330 cfu mL-1 in 2007 and 1,158 cfu mL-1 in 2009.66.7% of bacteria were Gram-negative. Most isolates were resistant to atrazine or oxamyl regardless of which pesticide medium they were originally grown. Only 2 of 30 tested isolates displayed intermediate and sensitive inhibition phenotypes, respectively, to oxamyl. Biochemical profiles were generally 70% or greater in similarity but still displayed diverse phenotypes. About half of isolates exhibited a unique biochemical phenotypic profile. Microbial communities in the canals could metabolize a variety of organic compounds and demonstrated high carbon substrate utilization and activity. Conclusion: Overall, indigenous pesticide-tolerant microorganisms were present in lowto- moderate densities, displayed diverse

    Full Text Available Este artigo aborda o desenvolvimento da indústria regional sul-rio-grandense e de seu mercado de trabalho no período compreendido entre 1920 e 1950. Nosso objetivo é considerar em que medida as condições observadas nessa indústria, que em 1920 pagava salários e operava com produtividade superiores à da indústria paulista, viram-se alteradas nas três décadas seguintes. Conclui-se que, embora o padrão de desenvolvimento industrial regional tenha se preservado em largos traços, o acréscimo de produtividade foi insuficiente para manter os elevados níveis relativos de salários, que também se viram prejudicados pela ampliação da oferta de trabalho.

One region may be such as to afford a livelihood for only a pastoral people; another may present opportunity for intensive agriculture; still another may contain hidden stores of mineral wealth that may attract large industrial development; and, taken together, these varied resources afford, the promise of long-continued prosperity for this or that State. Items of interest in civic development or references to significant epochs in the record of discovery and settlement may be interspersed. with explanations of mountain and valley or statements of geologic history. In a broad way the story of the West is a unit, and every chapter should be told in order to meet fully the needs of the tourist who aims to understand all that he sees. To such a traveler-reader this series of guidebooks is addressed. To this interpretation of our own country the United States Geological Survey brings the accumulated data of decades of pioneering investigation, and the present contribution is only one type of return to the public which has supported this scientific work under the Federal Government - a by-product of research. In the preparation of the description of the country traversed by the Denver & Rio Grande Western Route the geographic and geologic information already published as well as unpublished material in the possession of the Geological Survey has been utilized, but to supplement this material Mr. Campbell made a field examination of the entire route in 1915-1916.

De um total de 17 bovinos, dois morreram com curso clínico inferior a 12 horas, apresentando tremores musculares, andar cambaleante, reações agressivas, decúbito lateral e morte. À necropsia, o fígado estava moderadamente aumentado de volume e com acentuação do padrão lobular. Histologicamente, o fígado apresentava necrose de coagulação centrolobular, difusa, aguda e acentuada. As alterações patológicas associadas à presença e a evidência de consumo da planta pelos bovinos permitiram o diagnóstico.In June of 2007, mortality in cattle with clinical signs and lesions of acute hepatic insufficiency on a farm located in the hillside of Rio Grande do Sul mountain range was attributed to Cestrum intermedium consumption. From 17 bovines, two died up to 12 hours presenting clinical signs such as muscular tremors, incoordination, aggressiveness, lateral recumbence and death. Macroscopic lesions were found primary in the liver and were characterized by a slightly increased volume and diffuse accentuation of the lobules. Microscopically, the liver showed diffuse and accentuated centrilobular coagulative necrosis. The presence of Cestrum intermedium plants that was being ingested by the bovine associated with the hepatic lesions was decisive for the diagnosis.

    Full Text Available A busca pelo desenvolvimento faz parte da maioria das discussões que estão na ordem do dia na agenda contemporânea. Contudo, a definição sobre o que é desenvolvimento está longe de um consenso e suscita muitos debates. Neste sentido, este trabalho propõe uma análise crítica ao apoio que muitos setores da sociedade civil e representantes políticos têm dado a ‘nova’ alternativa de desenvolvimento para a região Fronteira Oeste do Rio Grande do Sul, focada na implantação de florestas que servirão de matéria-prima para empresas multinacionais de celulose. Neste contexto, sugere-se que o caminho para a melhoria das oportunidades e da qualidade de vida das pessoas não virá através de receitas prontas de desenvolvimento. De acordo com a perspectiva de desenvolvimento apresentada neste estudo, seria necessário considerar a relevância das características culturais locais, alem de criar condições para que as pessoas construam à sua maneira o desenvolvimento, de forma plural, respeitando as particularidades do território e favorecendo o fortalecimento das capacidades humanas. Deste modo, caberia ao Estado e seus representantes, nas diferentes instâncias, fomentar e apoiar iniciativas que garantam a autonomia, a diversificação e a diferenciação dos produtos e serviços oferecidos, além do empoderamento da população. Dessa forma, as pessoas passariam a ser consideradas como agentes do desenvolvimento e não apenas com beneficiários passivos de propostas prontas.

A Física é, em sua essência, uma ciência experimental, embora a realidade das salas de aula brasileiras tende a demonstrar o contrario, pautando a disciplina em conceitos estanques e um formalismo matemático excessivo. Felizmente, têm-se observado uma mudança desse cenário em âmbito nacional, e verificou-se nesse trabalho se o Rio Grande do Norte acompanha essa tendência. Para isso, foram elaborados dois momentos de análise distintos. No primeiro, Verificou-se a existência da prática experimental nas escolas de ensino médio. Para esse quesito, analisaram-se as escolas com os melhores indicadores IDEB. Por fim, um questionário foi elaborado e levado aos alunos de cursos de Licenciatura em Física, em diferentes cidades do Estado. Nesse momento, a aplicação do questionário distinguiu alunos da licenciatura em Física em ingressantes, concluintes e alunos cursando alguma disciplina de Física Experimental. Por fim, os resultados foram analisados e discutidos, mostrando uma evolução do ensino no Rio Grande do Norte, e uma prática experimental crescente e motivadora

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.

    Full Text Available Since dogs presenting several vector borne diseases can show none or nonspecific clinical signs depending on the phase of infection, the assessment of the particular agents involved is mandatory. The present study aimed to investigate the presence of Babesia spp., Ehrlichia spp., Anaplasma spp., Hepatozoon spp. and Leishmania spp. in blood samples and ticks, collected from two dogs from Rio Grande do Norte showing suggestive tick-borne disease by using molecular techniques. DNA of E. canis, H. canis and L. infantum were detected in blood samples and R. sanguineus ticks collected from dogs. Among all samples analyzed, two showed the presence of multiple infections with E. canis, H. canis and L. infantum chagasi. Here we highlighted the need for molecular differential diagnosis in dogs showing nonspecific clinical signs.

    Sedimentary facies were produced by Late Paleozoic Gondwana ice sheets in the Batovi and Suspiro regions, Rio Grande do Sul State, southern Brazil. The glaciogenic sediments, assigned to the Itararé Group of Paraná Basin, are the result of processes related to the subglacial, supraglacial and proglacial (ice-contact, glaciofluvial and glaciolacustrine) environments of the glacial depositional system. Several features developed by the action of glaciers were identified in the studied outcrops: striated and grooved pavements; striated, polished and faceted stones; finely laminated rhythmites bearing dropstones (varvites); erratic clasts and deposits exhibiting deformational structures such as folds, normal and reverse faults, and beds with abnormal dips. The available evidence suggests that the glacial episodes took place in a terrestrial (continental) context, far from direct marine influence.

  19. SELF-DESTRUCTION AND SELF-EXCLUSION: THE SUICIDE IN THE RURAL AREAS OF RIO GRANDE DO SUL – BRAZIL

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

    Full Text Available The aim of the present work was to study the diet of Lontra longicaudis in three limnic systems (anthropogenic shallow lakes, pluvial channel and coastal stream in Rio Grande do Sul State coastal plain, southern Brazil. Fishes were the most consumed item in all the three systems, being Mugilidae the most representative family in the pluvial channel and coastal stream and Cichlidae in the shallow lakes. Other identified items were mollusks, insects, crustaceans, amphibians, reptiles, birds and mammals and vegetal fragments. The high frequency of birds in the shallow lakes was remarkable, considering the lower frequencies of this item in previous investigations on the species diet. There was a high frequency of swamp eels (Synbranchidae, Synbranchus marmoratus in the pluvial channel and shallow lakes, which were usually absent or found in low frequencies in previous studies.

    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.

    127 fragments of pottery from excavation of four archaeological sites in Taquari Valley, close to Lajeado, State of Rio Grande do Sul, Brazil have been dated by thermoluminescence. After usual crushing, sieving, immersing in HCl solution and then in HF solution, accumulated dose, Dac, (or equivalent or paleodose) has been measured using additive method. The annual dose rate of natural radiation was estimated from uranium, thorium and potassium content in both soil from where these fragments have been collected and in fragments itselves. Cosmic ray contribution was added. The interesting finding is that the glow curves of quartz grains from sites enumerated 101, 110 and 114 indicated rare variety of quartz known as reddish quarts, whereas the glow curves of quartz grains, from the site numbered 107 are equal to these of usual quartz (hyaline). Results of dating and the properties of reddish quartz will be discussed. (author)

    Full Text Available The quality of pre-cooked pizza dough was investigated by assessing the occurrence of molds, yeasts and mycotoxins. Random sampling of commercial pre-cooked pizza cakes was done in different stores in the cities of Rio Grande and Pelotas, RS, between 1996 and 1997. The products were analysed on the sampling day and after storage at room (22-30ºC or refrigerated temperature (7ºC following the shelf life stated by the manufacturer (25,30 and 45 days. The results showed that mold and yeast contamination was frequently above the maximum limits (10³CFU/g-1 established by Brazilian guide lines, even in samples kept at refrigerated temperatures up to the end of shelf life. Although no mycotoxin contamination was detected, a strain of the Penicillium genus, isolated from various samples, produced ochratoxin A at refrigeration temperatures.

    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.

    Full Text Available Garlic is a vegetable that has economic and social relevance in Brazil. Rio Grande do Norte is among the consumer states, however, despite having regions with favorable conditions for growing garlic, it depends on imports of this product to meet its demand. The introduction of cultivars that have high yield and quality, and the adjustments in vernalization technology, which is a key issue for adaptation of new cultivars, are mechanisms that can contribute to garlic revitalization in areas previously producing this vegetable. Therefore, the objective of this work was to assess the quality characteristics of semi-noble garlic cultivars subjected to different bulb-seed pre-planting vernalization periods in two counties of the Western Mesoregion of Rio Grande do Norte State (RN, Brazil. Two experiments were simultaneously conducted in Barauna RN and Governador Dix-sept Rosado RN, from April to November, 2012. A complete randomized block experimental design was used with four replications. The treatments were arranged in split-plot design, with the plots consisted of cultivars (Gigante-do-Nucleo and BRS-Hozan and subplots consisted of bulb-seed pre-planting vernalization (4±1°C periods (0, 10, 20 and 30 days. The evaluations consisted of bulb diameter, pH, titratable acidity, soluble solids, total soluble sugars, reducing sugars, pungency, total solids and industrial index. The use of 10-day bulb-seed pre-planting vernalization increased the semi-noble garlic quality produced in Barauna and Governador Dix-sept Rosado. The cultivars Gigante-do-Nucleo and BRS-Hozan presented good prospects for industrialization, with good characteristics of flavor and aroma.

    The Santa Fe region is growing rapidly. The Santa Fe Group aquifer in the Espa?ola Basin is the main source of municipal water for the region, and water shortfalls could have serious consequences. Future growth and land management in the region depend on accurate assessment and protection of the region's ground-water resources. An important issue in managing the ground-water resources is a better understanding of the hydrogeology of the Tertiary Santa Fe Group. The Santa Fe Group includes the sedimentary deposits that fill the Rio Grande rift and contain the principal ground-water aquifers. The U.S. Geological Survey (USGS) is conducting a series of multidisciplinary studies of the Espa?ola Basin in northern New Mexico. Detailed geologic mapping, high-resolution airborne magnetic surveys, electromagnetic surveys, and hydrologic, lithologic, and hydro-geochemical data are being used to better understand the aquifer systems. Magnetotelluric (MT) surveys were completed as part of these studies. The primary purpose of the MT surveys was to map changes in electrical resistivity with depth that are related to differences in various rock types that help control the properties of aquifers in the region. Resistivity modeling of the MT data can be used to investigate buried structures related to the basic geologic framework of the study area. The purpose of this report is to release MT sounding data collected near geophysically logged boreholes in the study area, including the nearby Middle Rio Grande Basin. This MT data can be used in subsequent resistivity modeling. No interpretation of the data is included in this report.

    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.

    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.

    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.

    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.

    Full Text Available O presente trabalho tem como objetivo verificar os custos de produção e os seus componentes e a rentabilidade da produção ovina na Metade Sul do Rio Grande do Sul. A análise econômica de sete produtores teve a duração de 12 meses, compreendendo o período de agosto de 2006 a julho de 2007. Os dados mensais levantados consistem em todas as despesas e receitas e os valores referentes aos produtos consumidos nas propriedades. Foram realizados inventários patrimoniais e do rebanho ovino para o cálculo de depreciação e evolução dos ativos físicos. Os custos foram segmentados em variáveis, fixos, operacionais e totais. Indicadores econômicos foram formulados a fim de verificar a rentabilidade da atividade. Os custos variáveis e os de oportunidade foram as categorias que mais impactaram a formação do custo total. Dentro do custo operacional destaca-se o referente à mão-de-obra, sendo o grupo de custo que mais onera a produção ovina. A ovinocultura é uma atividade rentável, que é determinada pelo saldo positivo dos indicadores de margem bruta e renda operacional agrícola. Entretanto, a margem líquida apresentou valores negativos em todas as propriedades analisadas.The goal of this study is to examine the production costs and profitability of the sheep raising sector in the south of Rio Grande do Sul. The economic analysis included seven sheep farms throughout 12 months, between August of 2006 and July of 2007. Expenses, revenue and value of products consumed in the farm were measured monthly. Depreciation and physical assets were calculated based on patrimony and breeding stock inventory. Costs were divided in variable, fixed, operational and total. Economic indicators were computed to evaluate sheep production profitability. Results showed that variable and opportunity costs had the largest impact on total costs. In terms of operational costs, labor were the largest expense for sheep raising farms. Overall, sheep production

    Full Text Available Os cracídeos são aves silvestres que habitam as matas tropicais da América. Foram coletadas, no ano de 2007, amostras cloacais de 51 aves de dez espécies diferentes de cracídeos mantidos em cativeiros no Estado do Rio Grande do Sul. A partir dos swabs, colhidos assepticamente, foi realizado o isolamento e a caracterização bacteriana e o teste de susceptibilidade antimicrobiana dos isolados. Foram identificadas 93 cepas de bactérias. As bactérias mais frequentemente isoladas foram Escherichia coli, Staphylococcus spp. e Streptococcus spp. Todas as amostras foram negativas para o isolamento de Salmonella spp. O resultado do teste de sensibilidade mostrou que dentre as 93 cepas isoladas, todas foram sensíveis apenas ao imipinem. Adicionalmente, os menores percentuais de resistência foram observados frente ao cloranfenicol e ciprofloxacina. Os gêneros e espécies bacterianas com maior percentual de resistência a diferentes antibióticos testados foram Escherichia coli, Serratia marcescens, Staphylococcus aureus e Streptococcus spp. Com os resultados obtidos no presente trabalho, concluí-se, que a população de cracídeos estudada apresenta sua microbiota cloacal composta por vários gêneros e espécies bacterianas e que a multirresistencia pode ser um problema no futuro, uma vez que algumas cepas isoladas mostraram percentuais elevados de resistência a diferente antimicrobianos.Cracids are wildlife Galliformes which inhabits the America's tropical forests.

    Full Text Available Este artigo aborda o processo político que gerou os milhares de novos municípios no Brasil, utilizando o estado do Rio Grande do Sul como cenário das relações entre os poderes Executivo e Legislativo estaduais a partir da segunda metade do século XX. A recente fragmentação das unidades de governo local, assim como a institucionalização de uma federação em três níveis, é um fenômeno político restrito ao Brasil. Entre os estados, o Rio Grande do Sul foi aquele que mais intensamente fragmentou seu território: entre os anos de 1988 e 2000 foram criados 253 novos municípios nesse estado. Para descrever esse processo utilizarei uma abordagem histórico-institucional. As decisões favoráveis à criação e municípios predominaram no processo decisório estadual: 1 porque a consolidação da descentralização fiscal garantiu a estabilidade das transferências fiscais aos municípios; 2 devido à descentralização da regulamentação dos novos municípios em favor dos estados e 3 porque os poderes legislativos estaduais conquistaram grande autonomia no processo decisório da criação de municípios, como no Rio Grande do Sul, onde a participação popular na proposição legislativa, a prerrogativa exclusiva dos eleitores iniciarem a tramitação do processo e a manifestação popular no plebiscito limitaram a capacidade de controle do poder Executivo sobre o resultado legislativo.

    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. Vários fatores podem aumentar o risco de parto pré-termo.

Resultados: Foi identificada a evolução para ITUN em 12,61% das internações, predominando entre pacientes idosos e naqueles com SVD, além da supremacia da Escherichia coli entre os patógenos isolados e sua taxa de resistência às fluoroquinolonas de 50%. Conclusão: As cepas de E. coli isoladas mostraram sensibilidade às cefalosporinas de 2ª e 3ª gerações, amicacina e meropenem. As cepas isoladas de Klebsiella pneumoniae, segundo patógeno mais frequente, foram sensíveis apenas à cefoxitina e ao meropenem. As fluoroquinolonas foram, em nossa pesquisa, as mais prescritas como terapia empírica, o que pode justificar as elevadas taxas de resistência encontradas, tornando, então, seu uso impróprio para tratamento empírico de novos casos.

    1999-01-01

    In Texas, the Rio Grande forms the international boundary between Mexico and the United States and extends about 2,000 kilometers from El Paso to the mouth of the Rio Grande just south of Brownsville, where the river flows into the Gulf of Mexico (fig. 1). The North American Free Trade Agreement (NAFTA) has resulted in increased industrialization and population growth on both sides of the international boundary, which in turn has focused attention on environmental issues, including water quality and quantity in the Rio Grande. Nonpoint urban and agricultural runoff and wastewater discharges from industrial and municipal facilities are potential sources of organic compounds such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs). Historical applications of organochlorine pesticides such as DOT and chlordane in the United States and Mexico have resulted in a continuing source of these environmentally longlived compounds in the Rio Grande Basin. In the United States, all organochlorine pesticides either have been banned entirely or have use restrictions. However, in Mexico, the organochlorine pesticide DOT is still in use, although with some application restrictions.

    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. Les modèles antérieurs avaient des difficultés à reproduire ses conclusions sans l'aide de données hydrochimiques pour contraindre les taux et la distribution de la recharge. L'objectif de cette étude était d'utiliser une grande quantité de données hydrochimiques permettant de calibrer les paramètres du modèle, et notamment les taux de recharge. Le modèle a

    Full Text Available A fruticultura é uma atividade de grande importância na balança comercial brasileira e mais ainda para a região Nordeste. As diversas exigências do mercado exportador de frutas, como os certificados de qualidade, aliadas aos entraves internos da produção e da comercialização, entre os quais a ausência de padronização dos produtos e a falta de crédito, fizeram da intermediação das exportações uma prática regular. Grandes empresas, cooperativas, associações e ONG’s recebem as produções de muitos pequenos produtores e as exportam, conjuntamente com sua própria produção, quando também produzem. No Nordeste, é comum o agente exportador oferecer contratos de exportação aos produtores que incluem assistência técnica, administrativa e jurídica e os insumos necessários à produção. Este trabalho formula uma proposta de modelagem, usando a teoria dos jogos, mais especificamente a abordagem Principal-Agente, para os contratos de exportação entre produtores e exportadores da fruticultura. Aplicou-se a proposta para os pequenos produtores de manga do Rio Grande do Norte, e mostrou-se que a escolha do tipo de contrato da maioria dos produtores é ótima para ambas as partes e que estes contratos incentivam o produtor a aplicar esforço elevado na produção. Extensões da modelagem proposta podem incluir barganha nas negociações ou considerar um modelo de jogo dinâmico.Fruit production is an activity of great importance in the Brazilian commercial balance and even more in the Northeastern region. Intermediation is a regular practice in the fruit exporting market due to existence of requirements, such as quality certificates, and of internal problems in production and commercialization, such as credit limitations and absence of product standardization. Large companies, cooperatives, associations and NGOs receive products from many small producers and export them together with their own products. In Northeast, it is

    A seismic reflection survey by Chevron across the San Luis basin (northern Rio Grande rift) and San Juan volcanic field of southern Colorado is reprocessed with extended correlation to search for basement structure. The trace of the main bounding fault of the basin, a high-angle normal fault against the Sangre de Cristo Range, can be correlated to a wide zone of dipping reflection fabric and soles out at lower crustal depths (26-28 km). The deeper reflection fabric represent either broad extensional strain or pre-existing structure, such as a Laramide thrust system. The Sangre de Cristo bounding fault in San Luis basin does not sole out at mid-crustal depths but continues into the lower crust with a shallower dip. The basin architecture in the northern Rio Grande rift (San Luis basin) provides little if any evidence that the Sangre de Cristo bounding fault should flatten in a shallow listric fashion. This fault geometry is quite similar to the high-angle bounding fault in the Espanola basin but contrasts with less deeply-rooted faults in the Albuquerque basin in the central Rio Grande rift. Deeper soling out of the Sangre de Cristo bounding fault could be due to less extension in the northern Rio Grande rift and/or greater strength of the lithosphere compared to the central Rio Grande rift. Unequivocal Moho reflections beneath the San Luis basin cannot be identified, probably due to limited signal penetration or a gradational nature of the Moho. The majority of rift-related movement observed on the Sangre de Cristo bounding fault is post-Eocene. Either the western margin of the basin is marked by a tight monocline or a low-angle normal fault.

    Fossil charcoal, as direct evidence of palaeowildfires, has repeatedly been reported from several plant-bearing deposits from the Late Palaeozoic of the Northern Hemisphere. In contrast charcoal reports from the Late Palaeozoic deposits of the Southern Hemisphere are relatively rare in comparison to the Northern Hemisphere. Although the presence of pyrogenic coal macerals has repeatedly been reported from Late Palaeozoic coals from South America, no detailed anatomical investigations of such material have been published so far. Here is presented an anatomical analysis of charcoal originating from Early Permian sediments of the Quitéria Outcrop, Rio Bonito Formation, Paraná Basin, located in the central-eastern portion of Rio Grande do Sul, Brazil. This charcoal comes from two different coaly facies, and it was possible to scrutinize between three types, based on anatomical characters of the charcoal. Two of these charcoal types can be correlated to gymnosperm woods, and the other type corresponds to strongly permineralized bark with characteristic features of lycopsids. The presence of charcoal in different facies, ranging from parautochtonous to allochtonous origin, indicates that different vegetation types, i.e. plants which grew under wet conditions in the lowland as well as in the more dry hinterland, have experienced wildfires. Taking into account previous petrographic and lithological analyses from the facies in which the charcoal occurs and from the conditions of the wood and bark fragments, it was possible to speculate that the intensity of such wildfires most probably corresponds to forest-crown fires. Moreover, it is possible to state that wildfires have been a more or less common element in distinct Late Palaeozoic terrestrial ecosystems in the South American part of Gondwana. The data support previous assumptions on the occurrence of wildfires in the Early Permian of the Paraná Basin which were based solely on coal-petrographic data.

    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.

A modelagem adotada neste trabalho baseia-se em um processo pontual espacial, na qual se define uma medida de risco que varia continuamente sobre a região de estudo e estimada por meio de métodos de modelos aditivos generalizados. Essa abordagem possui a vantagem de permitir a incorporação, no modelo, de efeitos de determinantes individuais e ecológicos de risco sob forma simples e de fácil interpretação. Também permite a construção de contornos de tolerância que auxiliam na identificação de áreas de alto/baixo risco e de um teste global da hipótese nula de risco constante relativa à região.

Observou-se que no Estado houve um decréscimo na razão de mortalidade materna (0,98, contudo não foram encontradas diferenças nas medidas de estimativas (IC95% 0,87-1,10. A RMME foi maior em mulheres com mais de 40 anos, com baixo nível de escolaridade, de cor preta e sem companheiro. O período de maior estimativa de risco na morte materna foi durante a gravidez e o parto, e entre as principais causas diretas observadas foram constatadas hipertensão arterial e hemorragia. A mortalidade materna é um indicador importante que deve ser enfrentado e reduzido, pois a maior parte dos óbitos pode ser evitada.This study analyzed the epidemiological profile of maternal deaths that occurred from 2004 to 2007 in Rio Grande do Sul, by means of Maternal Mortality Rates and Specific Maternal Mortality Ratio. Data was obtained from the Health Information System database and 323 maternal deaths were identified. In order to analyze indicators, Poisson regression and statistical tests were carried out. A decrease in maternal mortality rates (0.98 was identified, although there was no difference in estimate measures (CI95% 0.87-1.10. Maternal deaths were more frequent in women who were over 40 years old, had low schooling, black skin and no partners. The period of highest risk of maternal death was during pregnancy and birth, and the main direct causes were arterial hypertension and bleeding. Maternal mortality is an important issue to be confronted and reduced, given most maternal deaths could have been avoided.

    Full Text Available The present study analyzed richness and specific composition of the fern community in fragments from the riparian forest of river ‘Cadeia’, under different levels of human impact, in Santa Maria do Herval, Rio Grande do Sul state, Brazil. An amount of 120 sample units were delimited, equitably distributed in three fragments (FI, II and III in which all species were surveyed and the richness was recorded. The floristic composition among fragments was compared using Jaccard’s index and spatial distribution of units was evaluated through multidimensional scaling. Richness data were presented in the form of rarefaction curves based on samples and non-parametric diversity estimators. A total of 40 species were found, belonging to 13 families. The greater floristic similarity was between FI and FII. Sample units from FI formed the most defined grouping and they had more exclusive species than the others. The rarefaction curve for the total sampling almost reached the asymptote and estimators indicated a maximum of 45 species, which means that the majority of species was surveyed at the study site. A decreasing gradient of mean richness per unit was observed as the urbanization increased in the matrix habitat of the fragments. These results form a data base to be used in management, conservation and reforestation measures in degraded riparian forests. They can be directly compared to results from other studies that used rarefaction and richness estimators, which is not possible to do with many of the surveys accomplished in Brazil so far.

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.

    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

    Full Text Available Visceral Larva Migrans syndrome (VLM results from the presence or migration of helminth larvae in humans, who nonetheless only play the role of paratenic hosts in the helminths' life cycle. In humans, VLM can be caused by larvae of various nematode species, chiefly those of the ascarid Toxocara canis, which can then be found at a variety of body sites, such as the liver, lungs, heart, and brain. Clinical and pathological manifestations depend primarily on larvae number and location, infection duration, reinfection occurrence, and host's immunological condition. Signs and symptoms may range from asymptomatic infection to severe disease. In humans, infection is acquired through ingestion of T. canis eggs present in soil, containing larvae in the infective stage7, 8, 9. Indeed, eggs of Toxocara sp. have been found in sandboxes in several public places in the city of Campo Grande, Mato Grosso do Sul state2. This study was carried out to detect the presence of anti-Toxocara antibodies in children attending the Pediatrics division of Hospital Universitário of Universidade Federal de Mato Grosso do Sul at Campo Grande, Brazil. Over the years 1992-94, 454 serum samples, obtained from children of 5.25 ± 3.28 years of mean age and selected at that hospital on the basis of eosinophil count greater than or equal to 1000/mm3 of blood, were tested for the presence of antibodies by means of the ELISA technique employing Toxocara canis larvae excretory-secretory antigens5. A high prevalence rate for toxocariasis (35.55% was found, which was observed to be associated with eosinophil levels lower than those usually reported in literature. Furthermore, a higher frequency of positive serology among boys was also observed (13 cases in contrast to only 3 among girls, a result also reported by other authors

Among these processes, suicide becomes a reality as a process of self-destruction and self-exclusion. These are sociopathologies of the development which are cre- ated in demonstrations of mental illness, depression and suicides, driven by a model of development imposed in the rural area through the economic incentive and, also, through all the economic speech carrying a project of hope. It is about the social and economic systems act- ing as generators of precariousness, human, familiar and psycho-philosophical costs, desocialization processes, self-generated alienation and self-cleaving, showing that it is increasingly necessary to think about the relation between the social and the individual in life and death processes. Resumo Este artigo trata da questão do suicídio no meio ru- ral no Rio Grande do Sul, Brasil, a partir da articulação deste fenômeno com o avanço capitalista no meio rural. Este último tem produzido novas formas de vida e tra- balho e, ademais, processos de adoecimento. Entre tais processos ganha corpo o suicídio enquanto processo de autodestruição, de autoexclusão. São as sociopatologias do desenvolvimento que se constituem em manifestações de doenças mentais, depressão e suicídios, alavancadas por um modelo de desenvolvimento imposto ao meio ru- ral através da incitação econômica e, ademais, por todo um discurso econômico portador de um projeto de espe- rança. É o sistema social e econômico agindo enquanto gerador da precariedade, de custos humanos, familiares, psicofisiológicos, de processos de dessocialização, de alienação autogerada, de clivagem de si apontando que se deve

    Full Text Available O crescimento industrial e o populacional têm aumentado os teores de metais pesados nos solos e impactado a qualidade desse recurso. Nesse contexto, as agências de proteção ambiental vêm despendendo esforços para o estabelecimento de índices que possam identificar áreas suspeitas de contaminação. Valores de Referência de Qualidade para Solos (VRQs refletem a concentração natural de determinada substância no solo, sem interferência antrópica. O trabalho objetivou estabelecer os VRQs para os metais Ag, Ba, Cd, Co, Cr, Cu, Ni, Pb, Sb, V e Zn exigidos pelo Conama, para composição da legislação direcionada ao monitoramento desses elementos nos solos do Estado do Rio Grande do Norte. Foram coletadas 416 amostras de solo em áreas de mata nativa ou com mínima influência antrópica. A abertura das amostras foi efetuada pelo método EPA-3051A, sendo os metais determinados por espectrometria de emissão ótica (ICP-OES e absorção atômica (AA. Os resultados do trabalho comprovaram que estudos regionalizados são essenciais para definição de VRQs. Os VRQs calculados para o Rio Grande do Norte foram mais restritivos que os de outros estados do país. A análise fatorial de confirmação dos dados foi útil para obtenção de VRQs mais confiáveis e demonstrou que para o Estado esses valores podem ser estabelecidos com apenas duas repetições por local de coleta. Nesse sentido, é primordial um planejamento prévio, de distribuição dos locais de amostragem, de maneira que os diversos compartimentos geomorfológicos, pedológicos e geológicos do Estado sejam representados.

    Within the Rio Grande Rift in New Mexico, gaps in Mesozoic and Tertiary confining units are common geologic features. They are created as a result of fault block rotation, erosion, lithological variations and emplacement of magmatic intrusions. These hydrologic windows were first proposed by Witcher (1988, Geothermal resources of southwestern New Mexico and southeastern Arizona: New Mexico Geological Society 39th Field Conference Guidebook, p. 191-197) as a mechanism to permit relatively hot geothermal fluids to discharge at the surface within the Rio Grande Rift. To explore the role of hydrologic windows in these occurrences, we have developed two-dimensional and three-dimensional hydrothermal models of both the Socorro and the Truth or Consequences geothermal resource areas. These finite-element models simulate groundwater flow, heat transfer, solute transport, and residence times. The 2D cross-sectional models help establish the depth of geothermal fluid circulation and crystalline-basement permeability structure required to account for hot-spring temperature conditions near the surface. The three-dimensional models help to assess the effects of water-table configuration and east-west oriented accommodation zones on shallow heat-flow patterns. We utilized carbon-14 groundwater age dating, salinity, and silica concentrations collected from wells and warm springs to calibrate these models. Apparent carbon-14 ages of groundwater samples collected from the 300-meter deep Woods Tunnel geothermal slim hole near Socorro and a 15-meter deep alluvial well from the Riverbend Spa in Truth or Consequences were 20,000 and 6,000 years old, respectively. Maximum geothermal temperatures based on silica concentrations at these two sites are estimated to range from 60 to 87 degrees Celsius. In order to reproduce observed temperature anomalies and groundwater residence times, groundwater circulation must have been within the crystalline basement, two to six kilometers beneath

    Full Text Available Estudos desenvolvidos com arroz irrigado por inundação no estado do Rio Grande do Sul têm evidenciado ausência de resposta desta cultura à adubação potássica, mesmo em solos com baixo teor de potássio disponível. Este trabalho objetivou verificar a contribuição da mineralogia destes solos como fonte potencial de potássio para a cultura do arroz. Para tal, selecionaram-se quatro solos representativos das zonas orizícolas do estado do Rio Grande do Sul (Planossolo Hidromórfico, Planossolo Háplico, Gleissolo Háplico e Chernossolo Ebânico cultivados com arroz irrigado. Estes solos apresentam baixos teores de potássio trocável e não apresentam respostas à adubação potássica. Nas amostras dos horizontes A e B dos quatro solos, foram analisadas a granulometria e a composição química. A mineralogia das frações areia, silte e argila foi identificada por difratometria de raios-X. Os principais minerais fontes de potássio foram os seguintes: na fração areia, feldspatos e micas; nas frações silte e argila, feldspatos, micas, esmectitas e esmectitas com hidróxi-alumínio entrecamadas. A quantidade de potássio total, nas frações granulométricas, diferiu entre os solos. As frações silte e argila apresentaram os maiores teores de K-total, exceto para o Planossolo Háplico, que revelou maior reserva de potássio na fração areia. A ausência, ou a baixa resposta, à adubação potássica na cultura do arroz irrigado nesses quatro solos pode ser explicada pelos minerais fontes de potássio que ocorrem nesses solos.
