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

    Violence is of major importance in the health profile of Brazilian metropolitan areas and should be treated as a public health problem. Spatial analysis methods can be highly useful for the surveillance and prevention of violence. This paper analyzes the spatial distribution of victims' place of residence in relation to the main causes of violent death in Porto Alegre (1996) in order to identify vulnerable areas. For motor vehicle accidents, homicides, and suicide, the victim's place of residence was pinpointed using the municipal Geographic Information System. The point patterns of health events and population density were analyzed using a Kernel smoother, visually compared. Some areas with higher concentration of events are similar to population distribution but differ from each other in the remaining high concentration areas, thus indicating specific micro-areas at risk. Areas of higher homicide risk are mainly located on the periphery of the more urbanized area, with worse socioeconomic conditions. Motor vehicle accidents are concentrated in areas that are simultaneously commercial and residential and are traversed by streets with heavy traffic. Suicide deaths are more evenly distributed over the territory. Identification of risk areas provides meaningful information for developing preventive and health promotion measures focusing on the events for which health policies may play a central role.

    This study focuses on users' views of factors influencing quality of care at a health care unit in the city of Porto Alegre, relating to access and receptivity. The data were collected using a semi-structured interview and participatory observation and treated using thematic analysis. The results compare ease and difficulties in geographic, economic, and functional access. Organization of services and professional competency were determinant factors in ease of reception, leading to user satisfaction. Poor reception and unsatisfactory professional performance were identified as difficulties. The study concluded that there is a need to increase the professional staff, train them in receiving users, implement a complementary modality for dental care, open the facility earlier for scheduling appointments, and prioritize care for residents of the catchment area.

    Full Text Available O objetivo desse artigo é analisar a distribuição espacial das residências de vítimas das principais causas violentas de morte no município de Porto Alegre em 1996. A violência tem importante impacto na saúde da população dos centros urbanos brasileiros, devendo integrar a agenda das ações de saúde. A incorporação de ferramentas de análise espacial pode enriquecer os meios de vigilância e prevenção. Foram geo-referenciados os locais de residência das vítimas de acidente de transporte, homicídio e suicídio utilizando-se o Sistema de Informações Geográficas. Os padrões de pontos dos eventos e o de densidade populacional foram analisados por alisamento Kernel e comparados visualmente. Certas áreas de maior concentração dos eventos são similares à distribuição da população; nas demais áreas de alta concentração, diferenciam-se entre si e delimitam microáreas de risco. Vítimas de homicídio concentram-se na periferia da área mais urbanizada; acidentes de transporte concentram-se em áreas mistas de residências e comércio; a distribuição dos suicídios é mais homogênea. A identificação das populações vulneráveis fornece informações importantes para a implementação de políticas de promoção da saúde e de prevenção.Violence is of major importance in the health profile of Brazilian metropolitan areas and should be treated as a public health problem. Spatial analysis methods can be highly useful for the surveillance and prevention of violence. This paper analyzes the spatial distribution of victims' place of residence in relation to the main causes of violent death in Porto Alegre (1996 in order to identify vulnerable areas. For motor vehicle accidents, homicides, and suicide, the victim's place of residence was pinpointed using the municipal Geographic Information System.

    Full Text Available The authors present a quantitative and qualitative study on homicides among teenagers in Porto Alegre, Rio Grande do Sul State, Brazil, based on a historical series during the 1990s and the life and death histories in this group, with a special focus on 1997. In that year there were 68 homicides in which the victims were from 10 to 19 years old. Of the 68, 62 were males and only 6 females, or a ratio of 10:1, showing that young males are more vulnerable and susceptible to being murdered. The data indicate that cause of death is influenced by gender culture and that homicides are based on power and status symbols characterizing a kind of virility. This expression of virility in the shaping of violence also appears in the domination of the female body observed in homicides with young women as the victims. The life and death histories of these teenagers highlight the pertinence of the gender-based analysis as a theoretical-analytical category, in addition to analyses considering socioeconomic aspects and social inequity.Este é um estudo quanti/qualitativo sobre homicídios entre adolescentes em Porto Alegre, tendo como base uma seriação histórica para a década de 90 e as histórias de vida e morte nesse grupo, particularizando o ano de 1997. Nesse ano houve 68 homicídios na faixa etária de 10 a 19 anos, dos quais 62 do sexo masculino e 6 do sexo feminino, numa razão de 10:1, mostrando que os homens estão mais vulneráveis e suscetíveis a morrer por essa causa de morte. Admite-se, a partir disso, que as formas de morrer sofrem influência das culturas de gênero e os homicídios se sustentam em símbolos e posições de poder que caracterizam um tipo de masculinidade. Essa expressão de masculinidade na forma de violência mostra sua face também no domínio sobre o corpo feminino, observado nas situações de homicídio envolvendo as mulheres adolescentes. Esses achados apontam para a conotação relacional e para a assimetria social

Results point to differences in the pattern of substance abuse, as well on risk behavior. Data may be useful for specific prevention strategies that take gender differences into consideration.

    A cross-sectional, population-based study was conducted on a random sample of 427 elderly individuals living in Porto Alegre, Brazil, to establish the nutrient consumption profile and verify its association with sociodemographic and health variables. Dietary intake was assessed using the 24-hour Food Recall Survey and the Dietetic Research Investigation technique. Seventy percent of the elderly respondents were women: 48.5% were between 60 and 69 years old; 68.8% had less than 8 years of schooling; 39% had a family income of between 2 and 5 minimum wages and 58.4% took no physical exercise. Hypertension was the most prevalent disease among the elderly and 54.9% were underweight. Men consumed more calories, protein, fiber, minerals and vitamins than women. Carbohydrate and calcium intake increases with advancing age, while zinc intake decreases. Physical exercise increased the intake of calories, magnesium, potassium and phosphorus. The higher the schooling the greater the intake of vitamins B6 and B12; the higher the family income, the greater the consumption of vitamin B6 and folic acid. The results show that there are nutritional deficiencies in the daily diet of the Brazilian elderly population, especially among women and individuals over 80 years of age. PMID:26691795

    Full Text Available O artigo analisa, com base numa pesquisa realizada no ano de 2003, o entendimento de agentes comunitárias de saúde do Programa Saúde da Família de Porto Alegre, Rio Grande do Sul, Brasil, sobre a noção de "negociação de sexo seguro" veiculada nas campanhas de prevenção à AIDS que são endereçados às mulheres. A pesquisa tinha como foco de análise alguns dos anúncios televisivos que integraram as campanhas implementadas pelo Ministério da Saúde no Brasil, no período de 1994 a 2000. A análise foi informada pelas vertentes dos estudos feministas e culturais que se aproximam da perspectiva pós-estruturalista de Michel Foucault e tinha como objetivo produzir subsídios para uma leitura crítica desse tipo de estratégia educativa para a prevenção da AIDS, em especial no que se refere às relações de gênero ali representadas. A análise das informações sugere que os conhecimentos e práticas que circunscrevem o discurso da negociação do sexo seguro incorporam, re-produzem ou veiculam representações hegemônicas de masculinidade e feminilidade e que estas diferenciam e hierarquizam mulheres em relação aos homens e/ou diferenciam mulheres de outras mulheres, produzindo e/ou reforçando preconceitos e desigualdades.This paper analyzes the understanding among female community health workers in the Family Health Program in Porto Alegre, Rio Grande do Sul State, Brazil, concerning the notion of safe sex negotiation promoted by the Brazilian government in AIDS prevention campaigns targeting women.

    Full Text Available Foram apresentados o risco relativo (RR e o risco atribuível percentual (RAP ao fator favelado de morrer, no primeiro ano de vida, em quatro setores de Porto Alegre, RS (Brasil, em 1980. O risco relativo médio de morrer no primeiro ano de vida foi de 2,4 a 3,62 vezes maior para o favelado, considerado um intervalo de confiança de 95%. O RAP ao favelado de morrer no primeiro ano de vida variou de 23,2% a 33,0% considerado um intervalo de confiança de 95%. O estudo dos cinco principais grupos de causas revelou que com exceção dos óbitos por anomalias congênitas, o risco relativo por essas causas foi sempre superior para o favelado; 1,8 vezes maior para afecções perinatais, 5,9 para a doença infecciosa intestinal, 6,1 para pneumonia e gripe e 8,0 para septicemia. Houve setores, como o intermediário sul, em que o risco relativo de morrer por septicemia foi 18,2 vezes maior para o favelado. Quanto ao risco atribuível, verificou-se que em média 28% da mortalidade infantil é atribuível a 18% de favelados. Considerados os principais grupos de causas, o RAP ao fator favelado foi de 12,8% para a mortalidade perinatal, 47,7% para doença infecciosa intestinal, 48,7% para pneumonia e gripe e 56,7% para septicemia. Mesmo levando em conta que o problema social e econômico é o principal determinante do fato de um indivíduo ser favelado, recomenda-se verificar a qualidade da assistência à saúde prestada às populações faveladas, pois é possível obter-se redução de morbi-mortalidade por aquelas causas, através da aplicação de cuidados médicos adequados, dirigidos prioritariamente às populações em piores condições de vida.The calculation of infant mortality relative risk (RR and attributable risk percent (ARP, related to shantytown residents (SR in Porto Alegre, Rio Grande do Sul State, Brazil, 1980 is non-shantytown, residents (NSR.

    Full Text Available Feeding associations between capybaras Hydrochoerus hydrochaeris (Linnaeus, 1766 and some bird species were registered in the Lami Biological Reserve, southern Brazil, through observations in a set of transects established in the five major vegetation types of the study area: shrubby and herbaceous swamps, wet grasslands, sandy grasslands and forests. Data included: date and time, vegetation type, bird species, number of individuals (birds and capybaras, type of prey consumed, foraging strategy of the birds and the behavior of the capybaras in relation to the presence of birds. Five species of birds were registered: Caracara plancus (Miller, 1777, Furnarius rufus (Gmelin, 1788, Machetornis rixosus (Vieillot, 1819, Milvago chimachima (Vieillot, 1816 and Molothrus bonariensis (Gmelin, 1789. The interactions were observed in the shrubby swamp (M. bonariensis, forest (C. plancus and wet grassland (F. rufus, M. rixosus, M. chimachima. The foraging strategies were: (1 use of the capybara as a perch, hunting from its back (M. rixosus, M. bonariensis; (2 use of the capybara as a beater, hunting in the ground (F. rufus, M. rixosus, M. bonariensis; (3 foraging in the skin of the capybara, by picking the ectoparasites (C. plancus, F. rufus, M. chimachima. Strategies (1 and (2 were employed to catch arthropods flushed from the vegetation. Sometimes, capybaras lay down and exposed the abdomen and lateral areas of their bodies to facilitate cleaning by M. chimachima, but the presence of other bird species seemed to be neutral to capybaras.Foram registradas associações alimentares entre capivaras Hydrochoerus hydrochaeris (Linnaeus, 1766 e aves na Reserva Biológica do Lami, sul do Brasil, por meio de observações em um conjunto de transecções estabelecidas nos cinco principais tipos de vegetação existentes na área: banhado arbustivo, banhado herbáceo, campo úmido, campo arenoso e mata.

Avaliou-se ainda o conhecimento do consumidor de carne bovina quanto à certificação da carne e quanto esse consumidor paga por este processo. A pesquisa foi realizada em uma rede de supermercados, mediante a aplicação de questionários dirigidos às pessoas próximas aos balcões com carne, independentemente da espécie animal. Os consumidores exigem alimentos com qualidade e certificados confiáveis que demonstrem e garantam a qualidade dos alimentos, porém, estão dispostos a pagar somente um pouco a mais pela certificação, em comparação ao valor atual de mercado, provavelmente pelo fato de sua renda mensal não permitir maior valorização desse atributo.The profile of beef meat consumers was analyzed, as well as the consumption of certificated meat, with the objective of obtaining data on the importance the of certification value at the purchasing occasion. The aim of this study was to evaluate the beef meat consumers awareness regarding the meat certification and how much they are willing to pay for this process. The data survey was carried out in only one supermarket chain from the city of Porto Alegre - RS, Brazil, which authorized the research interviewing people through questionnaires, close to refrigerator counters of any meat species. It was observed that consumers are demanding for food with quality attributes, with trustful certifications that testify these quality attributes. However, the data obtained from interviews with consumers showed that they are willing to pay only little more for certification than the current price, probably due to the fact that their average monthly income ranges from one to six minimum wages.

Em Porto Alegre, Estado do Rio Grande do Sul, há um grande tráfego diário e uma concentração de indústrias que podem ser responsáveis por emissões atmosféricas. Neste trabalho, estudou-se o comportamento das concentrações diárias de material particulado (PM10 desta cidade, considerando a influência dos elementos meteorológicos. A análise dos dados foi realizada a partir de estatísticas descritivas, correlação linear e regressão múltipla. Os dados foram fornecidos pela Fundação Estadual de Proteção Ambiental Henrique Luiz Roessler - RS (FEPAM e pelo Instituto Nacional de Meteorologia (INMET. A partir das análises pôde-se verificar que: as concentrações do PM10, medidos diariamente às 16h, não ultrapassaram os padrões nacionais de qualidade do ar; os elementos meteorológicos que influenciam nas concentrações do PM10 foram: a velocidade média diária do vento e a radiação média diária com relações negativas; as temperaturas médias diárias do ar e as direções, norte e noroeste, do vento, com relações positivas. As direções do vento que contribuem significativamente para diminuir as concentrações nos locais medidos são Leste e Sudeste.

    Objetivo: investigar como a gravidez não planejada e não aceita pode afetar o desenvolvimento da criança e quais os fatores sociodemográficos, das relações familiares e da rede social que podem interagir nessa relação. Método: participaram 82 mulheres que não planejaram a gestação, parte de um estudo longitudinal que incluiu todas as famílias do Bairro Vila Jardim de Porto Alegre, que tiveram filhos em hospital público entre novembro de 1998 e dezembro de 1999. Estas foram divididas em dois grupos: 73 mulheres que aceitaram a gestação até o quarto mês e nove delas que não a aceitaram. As participantes foram entrevistadas sobre: a gravidez e o parto, o relacionamento do casal e o impacto do nascimento da criança tanto para as suas vidas como para a dos pais da criança e famílias de origem. O desenvolvimento das crianças aos quatro anos foi avaliado pelo Teste de Denver II. Resultados: encontrou-se uma diferença significativa entre os grupos, demonstrando que os filhos de mães que não aceitaram a gestação apresentam maiores dificuldades de desenvolvimento da linguagem e da coordenação motora fina em relação às crianças cujas gestações foram aceitas até o quarto mês. Destaca-se que o grupo de mães que não aceitou a gestação apresentou problemas conjugais de moderados a graves e maior número de filhos. Conclusões: as crianças cuja gestação não foi aceita têm maiores riscos de apresentarem problemas de desenvolvimento, quando comparadas com aquelas fruto de gestações não planejadas, mas aceitas até o quarto mês. Esse achado salienta a importância de os profissionais de saúde identificarem durante o pré-natal a aceitação ou não da gestação, visto que este fator, assim como a qualidade da relação conjugal e o n

A determinação dos títulos de aloanticorpos auxilia na estimativa do risco e da severidade de reação transfusional, após transfusão não compatível, em uma população de gatos. O objetivo deste trabalho foi determinar a titulação de aloanticorpos e o risco de possível reação transfusional, em felinos domésticos sem raça definida, da cidade de Porto Alegre. Foram selecionados aleatoriamente 100 gatos clinicamente saudáveis, sem raça definida e sem parentesco entre si e sem histórico de transfusão prévia. Amostras de sangue foram coletadas da veia jugular e a titulação de aloanticorpos foi determinada no soro de gatos com tipo sanguíneo previamente definido. O risco estimado foi calculado de acordo com estudos prévios. No presente trabalho, 82,5 e 100% dos gatos do tipo A e B, respectivamente, apresentaram titulação variada de aloanticorpos. Com base nos títulos encontrados, verificou-se que uma transfusão de sangue, do tipo A ou AB, em gatos do tipo B apresenta risco de 33,3% de reação aguda severa e de 66,7% de reação aguda leve, nos receptores felinos. A transfusão de sangue do tipo AB ou B em gatos do tipo A apresenta risco de reação aguda severa em 1,0%; reação aguda leve em 37,1% e destruição prematura dos eritrócitos em 44,3% dos receptores felinos.

Na análise, observamos a estética visual e sonora, a estrutura narrativa e as principais temáticas. A cidade que surge nas telas de cinema com certeza é muito diferente do imaginário que existe sobre a cidade real. Ao invés de uma grande metrópole moderna, o que se percebe é uma cidade que mal consegue sair dos seus limites oitocentistas.

    International Nuclear Information System (INIS)

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

    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.

    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.

    A produção de leite apresenta grande expressão econômica, sendo uma das grandes geradoras de emprego no meio rural brasileiro. No entanto, as pequenas propriedades leiteiras possuem dificuldades de se estabelecerem, diante das exigências impostas pelo mercado. A busca pela qualidade na cadeia produtiva do leite no Brasil tem gerado grandes debates. A Instrução Normativa nº. 51 (IN nº. 51, do Ministério da Agricultura, Pecuária e Abastecimento, instituiu regulamentos técnicos, fixando condições e requisitos mínimos higienico-sanitários para a obtenção e produção da matéria-prima. Este trabalho objetivou analisar os aspectos higiênico-sanitários na obtenção do leite no Assentamento Alegre, município de Araguaína, TO, verificando se o leite produzido obedecia aos padrões da IN nº. 51. Os dados utilizados são de natureza primária e foram obtidos mediante entrevistas diretas realizadas com 41 produtores rurais, em março de 2007. Os resultados obtidos mostram que as normas da IN nº. 51 não estavam sendo respeitadas em relação ao manejo empregado na ordenha, no que diz resepeito à higienização do ordenhador e dos utensílios. Verificou-se, além disso, que parte do leite produzido era entregue nos laticínios dentro dos prazos estabelecidos pela legislação.

    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.

    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.

    2004-04-01

    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

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

    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.

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.

  11. Geomorphology of plutonium in the Northern Rio Grande

    International Nuclear Information System (INIS)

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

    Full Text Available This study aimed to assess the female homicide rate due to aggression in Rio Grande do Sul, Brazil, using this as a "proxy" of femicide. This was an ecological study which correlated the female homicide rate due to aggression in Rio Grande do Sul, according to the 35 microregions defined by the Brazilian Institute of Geography and Statistics (IBGE, with socioeconomic and demographic variables access and health indicators. Pearson's correlation test was performed with the selected variables. After this, multiple linear regressions were performed with variables with p < 0.20. The standardized average of female homicide rate due to aggression in the period from 2003 to 2007 was 3.1 obits per 100 thousand. After multiple regression analysis, the final model included male mortality due to aggression (p = 0.016, the percentage of hospital admissions for alcohol (p = 0.005 and the proportion of ill-defined deaths (p = 0.015. The model have an explanatory power of 39% (adjusted r2 = 0.391. The results are consistent with other studies and indicate a strong relationship between structural violence in society and violence against women, in addition to a higher incidence of female deaths in places with high alcohol hospitalization.

    2012-12-01

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

En esta novela las “dos Españas” se configuran en los personajes, algunos ficticios, otros históricos, sobre todo en las dos figuras femeninas principales que vienen a manifestar una búsqueda de libertad personal en la época de la posguerra española. A través de diferentes focalizaciones y narraciones se presentan unos paradigmas éticos o morales frente a la alteridad, al otro, que sirven para distinguir entre el bien y el mal, los buenos y los malos.Summary: Inés y la alegría, by Almudena Grandes (2010 is the first of a series of novels entitled Episodios de una Guerra interminable [Episodes of an endless War]. In this novel, the image of the “two Spains” is made up by the characters, some fictitious, others historical, and particularly by the two female protagonists who represent a quest for personal liberty in the years following the Spanish Civil War. Different focal points and narratives serve to present ethical or moral paradigms regarding "the other" that are used to distinguish between good and evil, good and bad people.

    Users' satisfaction is an important end-point to evaluate health services. This study has to do with an assessment of the level of user's satisfaction with relation to the last visit held in the primary health care network of Porto Alegre — RS, whose objective is to compare satisfaction of the users that assess the quality of the care process received as being of high APS score with that of the users who evaluate it as low APS score. A cross-sectional study based on the population, using the Primary Care Assessment Tool - PCATool, which enables the classification of the health services at the level of guidance to APS by means of the general score of primary care, defining it as high or low, in accordance with the users' experience. The satisfaction of the user was measured by a questionnaire consisting of twelve questions relative to the last visit, being measured by a 5-item Likert scale: "very good", "good", "regular", "bad" and "very bad". For the analysis, the results were grouped into two classifications, i.e. "satisfied", when referred as "veg good" or "good", and "dissatisfied" when referred to any of the other items. A significant difference was noticed in the 12 variables reflecting satisfaction in several aspects of the visit, showing higher satisfaction in users that classified the service as being of high score. The .general evaluation of the service presented 95.6% and 73.5% of "satisfied" in the services with high and low APS score, respectively (p<0.001. Users of services with high level of guidance to primary care obtain higher satisfaction in their visits. This higher satisfaction can benefit the decision-making process of the patient in face of the medical recommendations made.

    A satisfação dos usuários é um importante desfecho para avaliar serviços de saúde. Este estudo trata-se de uma avaliação do grau de satisfação dos usuários em relação à última consulta realizada na rede de atenção primária A

  8. Identification of thermotectonics events by 40Ar/39Ar methodology, in Jauru, Pontes e Lacerda and Rio Alegre Terrane - southwest portion of Amazon Craton

    International Nuclear Information System (INIS)

    The southwest portion of Amazon Craton, subject of these work, correspond to the southwest region of Mato Grosso State and is inserted on Rio Negro-Juruena, Rondoniana-San Ignacio and Sunsas-Aguapei geochronologic Provinces. This region is surrounded by three big terranes: Jauru, Pontes e Lacerda and Rio Alegre. The main aim of this study is to use the ages of termochronologic events obtained by 40Ar/39Ar methodology, including data of literature, to contribute with the study of the geotectonic evolution on this region. Twenty samples were analyzed and 40Ar/39Ar ages found for the Jauru Terrane vary of 1539 ± 3 Ma to 1338 ± 3 Ma, for the Pontes e Lacerda Terrane the interval obtained was of 946,1 ± 0,8 Ma to 890 ± 2 Ma and for Rio Alegre Terrane the ages are between 1407 ± 3 Ma to 1321 ± 2 Ma. U/Pb, Rb/Sr and Sm/Nd data from previous works, together with 40Ar/39Ar results allowed to obtain cooling average rates to each terrane. The Jauru Terrane units cooling age is equivalent to 1,52 Ga. The cooling average rates found to Alto Jauru Greenstone belt rocks is 2,4 deg C - 1,0 Ma and to Magmatic Arc Cachoeirinha is 10,8 deg C - 1,0 Ma. Stabilization age obtained for Pontes and Lacerda Terrane is about 900 Ma coherent with the cooling age of the Sunsas Aguapei Event (1,0 - 0,9 Ga) and cooling average rates calculate were the lower, equivalent to 1,0 deg C - 1,0 Ma. Cooling age found in Rio Alegre Terrane was 1,35 Ga, possibility correspond to collision age these terrane with Amazonian protoCraton and cooling average rates of 5,0 deg C - 1,0 Ma. Finally, younger age found of 900 Ma, coherent to the Sunsas - Aguapei Event, probably represent the last regional event that affected these rocks, characterizing the stabilization period of the southwest portion of Amazon Craton.

    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.

    Galindo, Rene; Wilson, Wade; Caldwell, Colleen A.

    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.

    Full Text Available The increased cultivation of olive trees in Rio Grande do Sul State and its potential production arouse the need to characterize the assemblage of insects in olive groves, especially those with potential as pests. Therefore, the insect fauna was sampled monthly for two years, in the canopy of olive trees, using beat cloth, and collection of buds in five municipalities in Southern Rio Grande do Sul State. The faunal indices analyzed were abundance, constancy, dominance and frequency. The olive caterpillar Palpita forficifera Munroe 1959 (Lepidoptera: Pyralidae and mealybugs Saissetia oleae (Olivier, 1791 and Saissetia coffeae (Walker, 1952 (Hemiptera: Coccidae are the main phytophagous insects in olive farms in the Rio Grande do Sul State, with potential to reach pest status. Eleven insect species were recorded for the first time in olive groves in Brazil. The occurrence of P. forficifera is a new record for the Rio Grande do Sul State.

Contaminants may be lethal or predispose fishes to sickness, being the analysis of aquatic organisms a good indicator of environmental quality. The violinha, Rineloricaria strigilata (Hensel, 1868, is a common loricariid catfish in the Guaíba lake basin, Rio Grande do Sul, Brazil, and has been selected as a bioindicator for being resident, occurring in more than 50% of the samples, and by showing externally detectable neoplasies. These are characterized by its dark pigmentation, bony plates hypertrophy, and hypertrophy and irregular arrangement of the odontodes. Histology showed hypertrophied epitelial tissues, with an increased number of secretory cells, blood cells, and melanina pigments, giving the dark appearance to the neoplasm. Observed frequencies of neoplasm were higher in lake Guaíba than in comparativo samples. Inside lake Guaíba, a pattern of distribution of neoplasm was observed, with the absence of neoplasm in fishes at the collected site that receives water from rio Jacuí, and frequencies of 3.04 to 16.81% in the collection localities in front of Porto Alegre and downstream localities, that receive water from rio Jacuí, rio dos Sinos and rio Gravataí, that drain urban and industrial area of Porto Alegre and neighborhood cities.

    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.

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

    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

    In order to evaluate the distribution of dermatophytes in Porto Alegre, the capital of the state of Rio Grande do Sul, Brazil, they were isolated from the skin, hairs and nails samples and retrospectively analyzed from June 1981 to June 1995, in two different institutions in the city of Porto Alegre: (i) the Serviço de Micologia do Instituto de Pesquisas Biológicas Jandyr Maya Faillace, da Secretaria de Saúde e Meio Ambiente do Rio Grande do Sul which attends the low income population (low and middle classes) and, (ii) Laboratório Weinmann, a clinical pathology laboratory which attends predominantly the higher income population (middle and upper classes), both which attend in the metropolitan area of Porto Alegre. The dermatophyte predominance of Trichophyton rubrum was confirmed (55.33%) followed by T. mentagrophytes (21.46%). The data obtained were compared with the existing prevalence data which were collected in the interior of the state over a period of 32 years (1960-1992). T. verrucosum, T. simii, Microsporum persicolor, T. schöenleinii, M. nanum and M. cookei were isolated in the interior and have not been found in the capital so far. On the other side, T. violaceum was, isolated in the capital and has not been found in the interior so far.

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

    Gigi RICHARD; Pierre JULIEN

    2003-01-01

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

    In geologically heterogeneous regions, such as the Rio Grande, archaeologists typically rely on petrographic analyses to determine ceramic provenance and reconstruct prehistoric trade patterns. Even in these regions, other methods are useful for elucidating trade patterns and/or resolving ambiguities from the petrographic data. Magnetic properties of Ancestral central Rio Grande Puebloan ceramics are being acquired to assess their use in identifying provenance, trade patterns, composition, manufacturing techniques, and firing conditions of ceramics, before and during the early European contact period (ca. A.D. 1325-1700) in New Mexico. Similar to the study of Moskowitz et al. (1987), we use a combination of bulk susceptibility, NRM, ARM, and SIRM intensity, AF response by NRM, ARM, and SIRM, thermal demagnetization of NRM and SIRM, and coercivity of remanence, to study temporal change in Rio Grande glaze wares from four archaeological sites in the northern Rio Grande (approximately 90 sherds per site). Rio Grande glaze wares were widely traded among Ancestral Puebloan groups before and during the European contact period. The ceramics are from the two earliest Spanish administrative centers in New Mexico, San Gabriel del Yungue and Palace of the Governors, and two mission pueblos, Pecos Pueblo and San Marcos Pueblo. Magnetic property data are being compared with petrographic observations to test the effectiveness of several magnetic measurements to identify, among other things, ceramic provenance. A tentative observation in our study is that bulk susceptibility values correlate with different ceramic provenances. The mean bulk susceptibility values for Galisteo Basin ceramics, tempered with augite monzonite and hornblende latite, are significantly higher (5.56E-04 and 4.91E-04 SI mass, respectively) than those for Pajarito Plateau ceramics, tempered with glassy tuff, tuff rocks, and andesite, (1.79E-04, 2.53E-04, and 2.58E-04 SI mass, respectively).

    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)

  15. Dinâmica de produção e comercialização da erva-mate no Rio Grande do Sul, Brasil

    Full Text Available A produção de erva-mate é uma das atividades não madeireiras que compõe o mercado agroflorestal brasileiro. No Rio Grande do Sul, este segmento é impulsionado pela tradição do consumo do chimarrão. Entretanto, nos últimos anos, observa-se que o estado gaúcho vem perdendo parcela significativa do mercado nacional, principalmente para o estado do Paraná. Nesse sentido, o presente estudo objetiva compreender a dinâmica produtiva e de comercialização deste produto, a partir da análise do comportamento dos preços pagos aos produtores rurais de erva-mate no Rio Grande do Sul, os preços diretos aos consumidores da erva-mate para chimarrão, além de dados estatísticos relacionados à produção de erva-mate. Evidencia-se que o modelo econométrico realizado para estimar o valor da erva-mate, embora indique a existência de associação linear positiva entre as variáveis dependente e independente, é considerado estatisticamente frágil. Ainda, cerca de 80% das variações no preço do quilograma da erva-mate no varejo de Porto Alegre são explicadas pelas variações no preço da arroba da erva-mate paga aos produtores rurais. Assim, reitera-se a necessidade de análises adicionais para identificar quais fatores exercem maior influência sobre o mercado da erva-mate, no contexto de expansão da demanda nacional e internacional

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

    International Nuclear Information System (INIS)

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

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

    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.

  18. Evidences of Holocene transgression on Domingos Petrolini Swamp, southern coastal plain, Rio Grande do Sul, Brazil

    2005-01-01

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

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

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

    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.

    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 < 0.001), showing more sensitivity to protein A-peroxidase than to protein G-peroxidase. The finding that wild 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.

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

    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.

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

    Full Text Available 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.

  4. 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.

    1989-09-01

    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.

    Full Text Available The occupation of Northern Coast Municipalities of the State of Rio Grande do Sul has intensified in the last decades due to two main processes: urbanization and tourism. The proximity to the GreaterMetropolitan Area of Porto Alegre, accessibility due to the confluence of a highway network and the diversity of environments paralleling the coast, have given this region a unique situation. Of rare beauty, these ecosystems (dune barriers, wetlands, lagoon systems and highland escarpments have been suffering significantly from impacts caused by human activity. The main objective of this paper is to characterize the Northern Coast municipalities of the State of Rio Grande do Sul, by way of territorial analysis of the urbanization and emancipation processes, demographic growth, migration and economic indicators, thus, offering elements that support local and regional public policy drafting. Taking into account the local 21 municipalities, the adopted regionalization seeks to contemplate both political-administrativeand physical-natural aspects. Such a characterization outlined four basic municipality profiles: permanent population urban areas, urban second residence areas, urban agro-industrial areas and rural municipalities.

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

    Full Text Available In the context of studies about space and school architecture, this article analyses the visual construction of the Fernando Gomes Elementary School, which was located in downtown Porto Alegre/RS, Brazil between 1913 and 1935. Designed by the engineer Afonso Hébert, head of the Department of Public Works in the State of Rio Grande do Sul/RS, the building was completed in 1922. In addition to functional elements, i.e., a large number of classrooms that would serve to increase the access of children to primary school, its monumental proportions incorporated a series of symbolic elements aligned with the ideals of the First Brazilian Republic (1889–1930. The documentary analysis was performed on the archives of the Directorship of Public Education and the Directorship of Public Works of Rio Grande do Sul, as well as various iconographic sources, capital improvement plans and periodicals of the time. The construction of the school inaugurated a new conception of the space and architecture of public elementary schools in the State, as the visible improvement and sanitation of the cities were considered of great importance in the period. The construction of school buildings was also one of the greatest advertising tools of the new Republican political regime.

    Full Text Available 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.

    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.

    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.

    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.

  4. 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.

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

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

    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

    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.

    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.

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

    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

  11. Comparative study of ceramic blocks for masonry produced in Paraiba and Rio Grande do Norte

    International Nuclear Information System (INIS)

    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 SiO2 and Al2O3 and Fe2O3 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)

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

    Full Text Available 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.

  4. Seismic Anisotropy Beneath the Eastern Flank of the Rio Grande Rift

    Benton, N. W.; Pulliam, J.

    2015-12-01

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

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

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

    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.

    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.

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

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

    Full Text Available Education in the Information Society is not just about training for the use of information and communication technologies (ICT, but involves the development of skills that allow the subject to engage effectively in a society permeated by digital technologies. It is understood that experiencing new forms of teaching and learning mediated by ICT refers to a (rethinking about the processes of teacher training. Method: The research “The ‘new ‘professional of education in the public schools of the state of Rio Grande do Sul (RS and the technologies in education” was conducted in two stages: first, quantitative, was responsible for the characterization of the professional who were hired between the years 2008 to 2010. The second, qualitative, involved the study of the use of technology in the teacher's activity, from the methodology of self-confrontation. Results: It was possible to draw a profile of the professionals of public education especially in relation to their entrance in the public service as well as the technological appropriation of teachers hired to work in a school in Porto Alegre. The article highlights the relevance of the methodology of self-confrontation as a space for teacher training in relation to technology in education. Conclusions: The technological appropriation is not due to existing training undergraduate and is not coming from the in-service training, although the government provides this type of qualification by the state policy of digital inclusion. Are the experiences of daily life that give the support for the work in this type of activity.

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

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

    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.

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

    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.

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

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

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

    Full Text Available Desde o final de 1998, um pequeno bivalve invasor, o "mexilhão dourado", Limnoperna fortunei (Dunker, 1857, oriundo do sudeste asiático, está presente no sul do Brasil. Foi provavelmente transportado, não intencionalmente, através de água de lastro para a Bacia do Guaíba, Rio Grande do Sul, Brasil. Em nosso meio, este molusco vem causando problemas de "macrofouling" com grandes prejuízos econômicos e danos à fauna e flora. As coletas foram qualitativas e quantitativas quinzenais no período de um ano, no lago Guaíba, Praia do Veludo (30°12'35"S, 51°11'68"W, ao sul do município de Porto Alegre. Utilizou-se rede de plâncton com abertura de malha equivalente a 36 mm, filtrando-se a quantidade de 30 litros de água. Descrevem-se brevemente as diferentes fases larvais com parâmetros do comprimento. Primeiramente reconhece-se um estágio ciliado, desenvolvendo-se em trocófora (comprimento de 80 µm a 125 µm com quatro fases distintas, e valvadas com a larva "D" (120 µm a 150 µm, o veliger de charneira reta (150 µm a 190 µm, o veliger umbonado (190 µm a 220 µm e o pediveliger (220 µm a 250 µm.

    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.

O Serviço de Dermatologia do Hospital de Clínicas de Porto Alegre tem disponibilizado a fototerapia para seus pacientes há um longo tempo, sem dados oficiais descritos até então. OBJETIVO: Estudar a prevalência das dermatoses encaminhadas à fototerapia do Hospital de Clínicas de Porto Alegre e descrever o número total de pacientes já encaminhados a esse setor e seu fototipo. MÉTODOS: Estudo transversal descritivo. A coleta de dados foi feita por revisão da totalidade das fichas de cadastro dos pacientes de fototerapia (dados secundários, as quais se encontram em um banco de dados no Serviço de Dermatologia do Hospital de Clínicas de Porto Alegre, de agosto de 1997 a julho de 2011. RESULTADOS: Ao todo 653 pacientes foram analisados. O fototipo 3 foi o mais prevalente (n=313. A distribuição da prevalência das dermatoses foi: vitiligo (279, psoríase (255, linfoma cutâneo de células T/ micose fungóide (29, doença do enxerto versus hospedeiro (15, esclerodermia (11, dermatite atópica (10, alopécia areata (6, parapsoríase (5, eczema (4, granuloma anular (4 e outros (35. Visto que vitiligo e psoríase foram as dermatoses mais prevalentes, eles foram analisados separadamente. Não houve diferença estatística entre as prevalências (P = 0, 177. CONCLUSÕES: Nossos resultados estão em conformidade com a literatura, e mostram que, apesar da psoríase ainda ser a principal indicação para a fototerapia, outras dermatoses estão sendo tratadas com ela, uma vez que seus resultados tem sido promissores.

Quase a totalidade das mulheres (95% realizou acompanhamento durante a gestação. O número médio de consultas foi de 7 e a maioria das mulheres (85% iniciou o pré-natal antes do quinto mês de gestação. A ausência ao pré-natal foi maior entre as mulheres mais pobres, na maioria adolescentes ou com idade acima de 40 anos. A incidência de baixo peso ao nascer, no grupo que não fez pré-natal, foi de 2,5 vezes maior comparado com as mães que realizaram cinco ou mais consultas. Da mesma forma o coeficiente de mortalidade perinatal foi três vezes maior (50,6/1000 entre as mães que não realizaram pré-natal e aquelas que consultaram 5 ou mais vezes (15,8/1000. Em relação ao risco gestacional que as mães apresentavam, o estudo mostrou uma inversão nos cuidados, já que um quarto das mulheres de alto risco receberam uma atenção pré-natal considerada adequada, enquanto esta proporção era menos de 10% nas mães de risco gestacional mais baixo. Este estudo sugere a necessidade de modificações no atendimento pré-natal, com estratégias bem definidas para aquelas pacientes com alto risco gestacional.All 5304 births in the hospitals of Pelotas, Rio Grande do Sul, Brazil in 1993 were studied.

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

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

    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.

    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

This State contributes with a good percentage of Brazilian freshwater fish culture, but its production has been stagnated in the last years. Production is based essentially on exotics fish species (mainly carps. Fish sales are concentrated in the Easter period, and sanitary inspection is still reduced. Fish farmers are making cooperatives in the central region of Rio Grande do Sul. The publishing of books of native species and the freshwater fisheries stagnation in the last years may stimulate the raise of native species, and some are suggested in this review.

    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.

    1990-10-01

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

    2012-01-01

    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.

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

    Full Text Available Phenological studies are important to understand the dynamics in forest ecosystems and also to enable adequatemanagement of their native species. In the Cerrado regions of the high Rio Grande river (south of Minas Gerais State, Caryocarbrasiliense species is found in highly distinct morphological forms with variable phenology. The aim of this study was to investigatephenological patterns within and between populations of both the tree and shrub forms of the individuals and to determine anycorrelation with abiotic factors. Thirty-five observations of the phenophases of the vegetative and reproductive stages were recordedevery two weeks for 18 months. The activity index was analyzed for each stage and further analyzed to see if there were associationswith the climate data by using Spearman s linear correlation. The species was deciduous but leaf growth became retarded during thedry season, at which point leaf flushing stopped and total leaf fall occurred throughout the rainy season. The flowering and the fruitproduction occurred in the rainy season. The reproductive phase can be either annual or sub-annual. The activity index showed highsynchronism within populations during the first flowering in all populations studied (> 80%. Flowering and mature fruits were highlysynchronized according to Spearman correlations. Tree and shrub individuals of C. brasiliense had very similar times for theirphenophases. The best period for collecting mature fruits in these regions is between February and March.

    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. This study reports the first molecular characterization of herpesvirus associated with fibropapilloma in turtles from the coast of RS.

    1988-10-01

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

    Full Text Available 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.

    Abstract Wasps integrate the floral visitors’ community and they can constitute a representative portion of the pollinators. For this reason, it was aimed to know and to analyze the floral preference of the Vespidae species and to investigate the use of floral resources for these wasps. The collects were performed between 2001 and 2008 in different localities of Rio Grande do Sul state (Estrela Velha, Santa Cruz do Sul, São Francisco de Paula e Sinimbu between 08:00 at 17:00 hours, utilizing entomological nets to catch the flower-visiting wasps. The collected specimens were deposited at the Coleção Entomológica de Santa Cruz do Sul (CESC. 1.483 specimens were captured belonging to 73 wasp species, whose 78.9% were Polistinae (30 species and 21.1% Eumeninae (43 species, visiting the flowers of 33 plant species classified in 16 botanical families; the families with the larger number of plant species were Asteraceae (12, Fabaceae (4 and Apiaceae (3. The plant species with the largest number of wasps collected was Schinus terebinthifolius Raddi (616, followed by Eryngium pandanifolium L. (137 and Eryngium horridum Spreng (122. The analysis of the trophic niche overlap of 26 species with four or more visited plant species, showed an overlap equal or higher than 50% in six cases.

    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.

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

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

    International Nuclear Information System (INIS)

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

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

  13. Permeability alteration in small-displacement faults in poorly lithified sediments: Rio Grande Rift, Central New Mexico

    Science.gov (United States)

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

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

    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.

O estudo objetivou acompanhar as complexas trajetórias percorridas pelas travestis, em busca de cuidados com a saúde. A pesquisa de campo realizou-se no período compreendido de janeiro a novembro de 2012, com travestis advindas de municípios do Rio Grande do Sul, residindo em Santa Maria no momento da pesquisa. Trata-se de metodologia qualitativa por meio de pesquisa etnográfica. Os resultados demonstraram que as interlocutoras evitam os serviços institucionalizados de saúde, optando por outras formas de cuidado. Destacou-se em relação a esse aspecto que, das 49 travestis que fizeram parte da pesquisa, 48 frequentavam o que denominavam de "casas de religião afro" ou "batuque". As interlocutoras indicaram sua opção em frequentar as "casas de religião afro" por identificá-las como espaços que, sem questionar as modificações corporais e sua orientação sexual, ofereciam formas de cuidado e proteção. Este artigo pode contribuir proporcionando certa visibilidade às inusitadas trajetórias das travestis em busca de cuidado em saúde.

    Apesar da astronomia ser um dos temas indicados pelos Parâmetros Curriculares Nacionais, observa-se que poucas mudanças ocorreram desde a implementação do mesmo em sala de aula. A presente pesquisa diz respeito sobre como os tópicos de astronomia estão sendo abordados pelos professores no ensino médio. Optou-se por aplicar um questionário com os professores que ministram a disciplina de física. Os mesmos trabalham em escolas estaduais situadas nas cidades de Ribeirão Pires e Rio Grande da Serra, ambas subordinadas a Diretoria de Ensino de Mauá, no Estado de São Paulo. O questionário foi aplicado durante o 2° semestre de 2006. Até o momento os resultados são preliminares. Dos 82,0% dos professores que responderam ao questionário no município de Rio Grande da Serra, 66,7% não aplicaram nenhum tópico de astronomia, 77,8% não utilizaram qualquer tipo de programa computacional, 66,7% não utilizaram laboratório, que 77,8% nunca levaram os alunos a museus e ou planetários e que 66,7% não indicaram qualquer tipo de revista ou livro sobre astronomia aos seus alunos. No município de Ribeirão Pires, 53,3% dos professores responderam ao questionário, destes 75,0% não aplicaram nenhum tópico de astronomia, 93,8% não utilizaram qualquer tipo de programa computacional, 75,0% não utilizaram laboratório, 81,3% nunca levaram os alunos a museus e ou planetário e 56,3% não indicaram qualquer tipo de revista ou livro sobre astronomia ao seus alunos.

    Full Text Available Os bifenilos policlorados (PCBs estão entre os poluentes mais tóxicos presentes no meio ambiente, apresentando os alimentos como principal fonte de exposição humana. Com base nisso, este trabalho teve como objetivo determinar os sete PCBs indicadores de contaminação ambiental em 22 amostras de arroz e 18 de feijão do estado do Rio Grande do Sul, Brasil. Além disso, objetivou-se calcular a ingestão diária estimada de resíduos, a partir da contaminação existente no arroz e feijão, assim como determinar o teor de gordura das amostras para correlacioná-lo com os níveis de PCBs. A extração e purificação dos compostos foram realizadas pelo método QuEChERS, seguido de identificação e quantificação por CG-EM. Os PCBs 153 e 101 apresentaram as maiores concentrações médias nas amostras de arroz e feijão, respectivamente. Considerando o somatório dos PCBs, este foi de 4,39ng g-1 para o arroz e de 4,17ng g-1 para o feijão. Quanto à ingestão diária estimada, esta foi de 7,82ng kg-1 e de 3,14ng kg-1 de peso corporal por dia, para o arroz e o feijão, respectivamente. Em relação ao percentual de gordura, o arroz e o feijão apresentaram teores de gordura de 0,32% e de 1,1%, respectivamente. No entanto, a correlação com os níveis de PCBs não foi significativa. Os resultados demonstram que o estado do RS apresenta fontes importantes de contaminação desses resíduos químicos persistentes

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

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

    Petrakis, Roy E.

    Riparian ecosystems of the southwestern United States are highly valuable to both the ecological and human communities which surround them. Over the past century, they have been subject to shifting management practices to maximize human use, control, ecosystem service, and conservation. This creates a complex relationship between water policy, management, and the natural ecosystem necessitating research on spatial and temporal dynamics of riparian vegetation. The San Acacia Reach of the Middle Rio Grande, a 60 mile stretch from the San Acacia Diversion Dam to San Marcial, has experienced multiple management and river flow fluctuations over the past 80 years, resulting in threats to riparian and aquatic ecosystems. This research was completed through the use and analysis of multi-source remote sensing data, GIS, and a review of the on-the-ground management decisions to better understand how the location and composition of the riparian vegetation has been affected by these shifting practices. This research focused on four phases, each highlighting different management practices and river flow patterns during the last 80-years. Each of these periods provides a unique opportunity to observe a direct relationship between river management and riparian land cover response and change. Overall, management practices reduced surface river flows and limited overbank flooding and resulted in changes in the composition, density, and spatial patterns of the vegetation, including increased non-native vegetation growth. Restoration efforts over the past few decades have begun to reduce the presence of non-native species. Despite these changes, this ecosystem was shown to be extremely resilient in maintaining its function/service throughout the entire study time frame.

    Full Text Available The aim of this study was to evaluate the composition and quality of raw milk that was refrigerated in tanks, according to the farm structures, bovine diet, and production levels of the dairy producers that provide milk for the Association of Small-Scale Ranchers of the Angicos Wilderness (ASRAW. Data were collected from 47 dairy farmers from different cities of the state of Rio Grande do Norte who are associated with ASRAW. Twenty-three tanks were sampled throughout the month of June 2013, with two collections per week and five samples per tank, for a total of 920 samples. The properties were characterized according to the type of tank (private or community, the food provided during milk collection (voluminous or voluminous and concentrated, the structure of the dairy producer (family producer or non-family producer, and the amounts of each component. Analyses of fat content, total protein, casein levels, lactose levels, total solids, degreased dry extract (DDE, freezing point, urea levels, somatic cell counts (SCC, and antibiotic residues were performed. Statistical analyses were conducted for each group, and the means were compared by Tukey tests, with a critical significance level of 5% probability calculated with the PROC GLM procedure of the SAS® program. Most components differed significantly for each parameter. The highest difference was noted between the urea and SCC levels, which was probably due to the wide variety of dairy producer profiles. The SCC values exhibited the largest amplitude variations. Most milk components significantly differed according to the strata, producer, food, and tank. These changes probably had little influence on the animal’s physiology and productivity. Therefore, despite the small variations in the components of the milk supplied by ASRAW, the different types of milk storage tank, milk volume produced, and type of dairy producer affected the overall milk quality.

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

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

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

Additionally, the amount of energy produced in kW.h.m-3 and kW.h.ha-1 for all species was estimated. The experiment was conducted in a completely randomized design with eight treatments (species, four replicates (sample trees, adding up to 32 sampling units. There were significant differences, at 5% significance between treatments for all variables, except for hydrogen percentage and C/H ratio. It was concluded that Mororó´s wood shows high energy potential, and along with Jurema Preta, presents higher energy generation per m3, and provides greater economy for the same productivity. The energy potential Jurema Preta wood´s stands out among the species. Pereiro´s wood stands for energy production per hectare. Marmeleiro and Jurema Branca´s woods are indicated as direct burning potential and Imburana´s wood is not recommended for power generation.

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

    International Nuclear Information System (INIS)

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

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

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

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

    Abstract. Some neotropical social wasps which are associated with some vertebrates and other insects like ants, and these interactions are reported for decades, but little is known about the presence of these in the Caatinga and Atlantic Forest. This study describes the first association's record between nests of Polybia rejecta (Fabricius wasp and Azteca chartifex Forel ants in the transition area of the Atlantic Forest and Caatinga in Rio Grande do Norte. The observations were in a private forest in Monte Alegre, from October 2009 to September 2014 through active search for colonies, use of ad libitum method, photography and collection of specimens with traceability. In the study area were found four active colonies and one abandoned of P. rejecta, all associated with nests of A. chartifex with approach of 20-30 cm. It was found that when the colony of P. rejecta was disturbed, they became aggressive towards the disturbance object, whereas the ants gathered in order to fend off a potential predators. These interactions appear to benefit wasps and ants, it is assumed that is possible that wasps attack ants's predators, whereas the ants attack the wasps's predators. This study corroborates the hypothesis that the association between the social wasps P. rejecta and A. chartifex ants is beneficial for both species, and probably the wasps are the most benefited, but also shows the non-exclusivity of this association for the biomes up then reported.

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

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

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

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

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

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

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

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

    Full Text Available Objective: To verify the association between age and gender regarding HIV seropositivity in drug users who seek public health centers in Porto Alegre, Brazil. Methods: The authors designed a cross-sectional study with a convenience sampling of 695 men and women aged above 15, who reported recent drug use and risk behaviors to HIV exposure. We used a standard questionnaire (CRA, Brazilian version of the RAB, Risk Assessment Battery to assess risk behaviors and we collected blood for HIV testing. Results: Most individuals were males (75,8%, with a mean age of 29.4 years, less than seven years of schooling (42,4%, and family income equal or superior to four minimum wages (46%. There was no significant association between gender and seropositivity. Multivariate analyses showed that individuals aged above 30 had a three-fold increased odds of being seropositive over subjects aged 20 or less. Intravenous drug users who had been using drugs since 1980 had five-fold odds of seropositivity and those who had been using them in the month prior to the interview had four-fold odds. Discussion: Subjects aged more than 30 showed higher odds of seropositivity than the younger group. This is possibly due to a higher use of intravenous cocaine and to having more risk behaviors along their lifetime. There was no difference in seropositivity between genders, what differs from current data of other studies, if we take into consideration that rates of populational seropositivity among women have increased, mostly among drug users, who are, therefore, at 'double risk'. The development of further studies is mandatory in order to assess gender and age as risk factors for seropositivity, whether to confirm or to deny these findings, and to plan specific strategies for high-risk groups.Objetivo: Verificar se idade e gênero estão relacionados à soropositividade para HIV em usuários de drogas que procuram centros de atendimento em saúde de Porto Alegre.

Métodos: Foram entrevistados 142 UDI, utilizando uma entrevista estruturada para levantamento de fatores de risco. Foram analisadas características demográficas e das relações sexuais, utilizando-se como desfechos de interesse o status sorológico e as características do uso de drogas, tais como freqüência e tipo de droga utilizada. Resultados: 97% dos indivíduos havia injetado cocaína (8,6 dias do mês, 9,3 vezes por dia e usado álcool e maconha no mês prévio à entrevista; apenas 44 apresentavam testes HIV (54,5% soropositivos. Quase 90% haviam recebido aconselhamento para HIV, porém a mudança de condutas aconteceu somente numa parcela dos casos, sem informação adequada sobre limpeza de seringas; 53% dos indivíduos relataram compartilhamento de equipamento prévio à coleta de dados, utilizando 16,2 vezes a mesma seringa. Os entrevistados eram sexualmente ativos e predominantemente heterossexuais, com uma média de sete relações por mês; 44% não usou camisinha nas relações sexuais e 48% afirmou ter utilizado pelo menos álcool antes ou durante as relações. Conclusões: Os achados sugerem que o aconselhamento é importante para modificar hábitos dos UDI mas não contempla necessidades de usuários recreacionais. A limpeza de seringas é infreqüente, talvez produto da pouca informação sobre práticas de risco. Os UDI são sexualmente ativos, heterossexuais e na maioria têm poucos parceiros, o que pode justificar o baixo uso de preservativos nessa amostra. É possível que o uso freqüente de drogas antes ou durante as relações contribua para tal fato.Introduction: This paper presents data on a sample of inner city injection drug users

    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.

    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.

    The aim of the present study was to assess the acaricide resistance of tick populations in the western-central region of Rio Grande do Sul (Brazil), which has not previously been reported. Fifty-four cattle farms were visited and specimens of Rhipicephalus (Boophilus) microplus were collected and subjected to the adult immersion test, using nine commercial acaricides in the amidine, pyrethroid and organophosphate groups. Climatic data, including monthly precipitation, were recorded. The results from the present study demonstrated that seven of the acaricides analyzed presented mean efficacy values of less than 95%, with large differences among the products tested. Nine of them exhibited satisfactory and unsatisfactory acaricide results on at least one farm. In conclusion, the farms located in the western-central region of Rio Grande do Sul, Brazil, exhibited populations of R. (Boophilus) microplus with variable degrees of susceptibility to different acaricides, thus suggesting that resistance to the active compounds exists. It is suggested that treatment protocols should be implemented at the beginning of winter and summer, using the acaricides that showed efficacy in the adult immersion test. PMID:25271453

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

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

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

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

    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.

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

    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.

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.

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

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

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

    Science.gov (United States)

    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

    Seepage investigations have been conducted annually by the U.S. Geological Survey from 1988 to 1998 and from 2004 to the present (2015) along a 64-mile reach of the Rio Grande from below Leasburg Dam, Leasburg, New Mexico, to above American Dam, El Paso, Texas, as part of the Mesilla Basin monitoring program. Results of the investigation conducted in 2015 are presented in this report. 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 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.Um novo gênero e espécie de glandulocaudine, Lophiobrycon weitzmani, é descrito com base em exemplares coletados em riachos de cabeceira da drenagem do rio Grande, sistema do alto rio Paraná, Estado de Minas Gerais, sudeste do Brasil.

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

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

    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.

    Full Text Available INTRODUÇÃO: A Esquizofrenia é transtorno psiquiátrico crônico grave que acarreta importantes déficits psicológicos, sociais e vocacionais. Os antipsicóticos clássicos são amplamente usados como tratamento, mas comumente produzem respostas incompletas, toxicidade e efeitos extrapiramidais. A clozapina foi importante aquisição na terapia antipsicótica. Mostrou-se com eficácia legítima em 30-61% das psicoses e baixa incidência de efeitos adversos. MÉTODOS: Relato da experiência clínica de 56 pacientes com Esquizofrenia Refratária incluídos no programa de fornecimento gratuito da clozapina pela Secretaria da Saúde e do Meio Ambiente do Estado do Rio Grande do Sul em convênio com o Hospital de Clínicas de Porto Alegre. RESULTADOS: A média dos escores da Brief Psychiatric Rating Scale (BPRS foi inicialmente 77,9 (DP=16,1 e, após noventa e três meses de tratamento, 41,1 (DP=16,2. Dois pacientes abandonaram o programa e um foi excluído por agranulocitose. Houve quatro internações. DISCUSSÃO: Apesar de sua comprovada eficácia e aplicabilidade, a clozapina não está livre de efeitos adversos: hipotensão ortostática, taquicardia, visão turva, xerostomia, hipersalivação, constipação e sedação são comuns. As alterações hematológicas ocorrem em 0,05 a 2,8% dos casos. Ainda, o alto custo restringe seu uso. CONCLUSÕES: Houve melhora significativa e mantida dos pacientes que participaram do programa. Doenças com maior tempo de evolução obtiveram menor resposta, provavelmente relacionada a alterações neurofisiológicas e neuroquímicas. Vale ressaltar a importância do início precoce do tratamento e a necessidade da participação do Estado, no sentido de oferecer suporte psicossocial e financeiro para a otimização do tratamento desses pacientes.INTRODUCCIÓN: La Esquizofrenia es un trastorno psiquiátrico crónico grave que ocasiona importante déficit psicológico, social y vocacional.

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

    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

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

    Gilbert J. Gonzales

    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

The interviews were held in specific locations like University outpatient clinics and hospital wards and a center run by the city government. A full 62.9% were diagnosed as high-risk pregnancies. Mean self-esteem according to the Rosenberg scale was 9.2 (SD = 4.6. Variables showing a positive, significant association with self-esteem were age, schooling, and income. Perception of risk to the unborn infant's health and parity were both negatively associated with maternal self-esteem. These high-risk pregnant women also showed higher self-esteem than low-risk pregnant women.

    Full Text Available A infecção pelo Neospora caninum é distribuída mundialmente e tem sido considerada uma importante causa de abortos em bovinos, que são hospedeiros intermediários do protozoário. O presente artigo relata um estudo sorológico da infecção pelo N. caninum em 1.024 amostras de bovinos, ovinos e bubalinos, oriundos de 55 propriedades em 16 municípios do Estado do Rio Grande do Sul (RS. Anticorpos contra o agente foram detectados por um teste imunoenzimático do tipo ELISA em 11,4% (89/781 das amostras de bovinos, em 14,6% (24/164 dos bubalinos e em 3,2% (2/62 dos ovinos. Bovinos soropositivos foram detectados em todos os municípios amostrados. Esses resultados demonstram que a infecção pelo N. caninum encontra-se amplamente difundida no rebanho bovino e também em outras espécies de ruminantes do Estado. Aliados a relatos clínicos e histopatológicos anteriores, esses resultados ressaltam a importância do N. caninum como agente etiológico de falhas reprodutivas em bovinos no RS.The infection by Neospora caninum is distributed worldwide and has been considered an important cause of abortion in cattle, which are intermediate hosts of the parasite. The present article reports an serological survey of the N.caninum infection in 1024 serum samples of cattle, sheep and water buffalo from 55 herds in 16 counties of the state of Rio Grande do Sul (RS. Antibodies to the agent were detected by ELISA in 11.4% (89/781 bovine samples, in 14.6% (24/164 water buffalo and in 3.2% (2/62 sheep sera. Positive cattle were detected in all tested counties. These results demonstrate that N. caninum infection is widespread among bovine and other ruminants in the state. Taken together with previous clinical and pathological reports, these results are indicative of the importance of the parasite as the etiological agent of reproductive failure in cattle in RS.

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.

Na primeira, foram obtidos escores de eficiência por meio da estimação de fronteiras de produção não paramétricas DEA (Análise de Envoltória de Dados e FDH (livre descarte. 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.

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

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

    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 Este trabalho tem como objetivo identificar a quantidade de gases causadores de efeito estufa emitidos anualmente pela bovinocultura no Estado do Rio Grande do Sul. A partir dos resultados, é analisada a viabilidade econômica, em termos de instalação de créditos de carbono, da instalação de biodigestores nas propriedades rurais, calculando-se a quantidade de toneladas medidas em unidades de gás carbônico, equivalentes por ano, que a adoção dessa tecnologia permitiria mitigar. Entre os resultados obtidos, tem-se que a instalação de biodigestores é viável apenas para propriedades que possuem mais de 20 animais, as quais representam 63% do rebanho bovino gaúcho, e a mitigação de 29.548,26ton equiv.

    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.

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

    2009-10-01

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

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

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

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

    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 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 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. Fifty one cloacal swabs were collected from 10 different species of captive cracids from the Rio Grande do Sul State during 2007. The cloacal swab samples were submitted to bacterial isolation, identification and, subsequently; antimicrobial susceptibility testing. Ninety three bacterial isolates were obtained from the cracid population examined. The most prevalent among the isolates were Escherichia coli, and bacteria from the Staphylococcus and Streptococcus genera. All samples

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

    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.

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.
