The objective of the present article is to introduce Zaira de Bittencourt Martins’s contributions to psychoanalysis in Rio Grande do Sul, identifying her as pioneer in child psychoanalysis in this State. Starting from a historic research based on interviews with psychoanalysts, bibliographical sources and contacts with relatives, the author composed a biographical outline of the psychoanalyst above mentioned. Zaira Martins, together with her husband, the psychiatrist and psychoanalyst Mario Martins, immigrated to Argentina in 1944, and in 1947 was recognized as an analyst by the Argentinian Psychoanalytic Association. On her return to Brazil she became the first non physician woman to make part of the Psychoanalytic Society of Porto Alegre, collaborating with her foundation, in 1963. She played the pioneer role as child psychoanalyst and contributed in the dissemination of Kleinian ideas in her State. She also contributed in the formation of young analysts who were beginners in the child analyst field, through courses and supervisions.

The aim of this study was to describe the distribution of waist circumference (WC) and WC to height (WCTH) values among Kaingang indigenous adolescents in order to estimate the prevalence of high WCTH values and evaluate the correlation between WC and WCTH and body mass index (BMI)-for-age. A total of 1,803 indigenous adolescents were evaluated using a school-based cross-sectional study. WCTH values > 0.5 were considered high. Higher mean WC and WCTH values were observed for girls in all age categories. WCTH values > 0.5 were observed in 25.68% of the overall sample of adolescents. Mean WC and WCTH values were significantly higher for adolescents with BMI/age z-scores > 2 than for those with normal z-scores. The correlation coefficients of WC and WCTH for BMI/age were r = 0.68 and 0.76, respectively, for boys, and r = 0.79 and 0.80, respectively, for girls. This study highlights elevated mean WC and WCTH values and high prevalence of abdominal obesity among Kaingang indigenous adolescents.

Eficiência agrícola (EA) é utilizada como indicador do nível de desenvolvimento agrícola regional, expressando, por meio da relação entre as produtividades real e atingível, o nível tecnológico empregado nas culturas. Com base nisso, o objetivo deste estudo foi avaliar a EA das culturas da soja, do milho e do trigo para o estado do Rio Grande do Sul, entre os anos de 1980 e 2008, identificando os principais fatores que as condicionaram. A EA foi obtida pela relação entre a produtividade atingível (PA) e a real (PR). A PR foi obtida junto ao banco de dados do Instituto Brasileiro de Geografia e Estatística (IBGE). A PA foi obtida pela estimativa da produtividade potencial (PPf), pelo método de Zona Agroecológica da FAO, deflacionada pelo déficit hídrico em cada uma das fases da cultura. Verificou-se que as EAs médias para as culturas do milho, da soja e do trigo para o RS foram iguais a 54, 61 e 43%, respectivamente. Nas localidades de Santa Rosa, São Borja e Veranópolis, a EA para a soja foi, ao contrário das demais localidades, negativa. Os principais fatores que contribuíram para o aumento da EA, na maioria das localidades, foram: mudanças no uso e fertilidade do solo; uso de mecanização agrícola; preços pagos pelas commodities; investimentos em pesquisa e desenvolvimento; adoção do zoneamento de risco climático; e melhoramento genético.

The estimation of reference evapotranspiration (ETo), used in water balance, allows to determine soil water content, assisting on irrigation management. The present study aimed to compare simple ETo estimating methods with the Penman-Monteith (FAO), in the folowing time scales: daily, 5, 10, 15 and 30 days and monthly in the counties of Frederico Westphalen and Palmeira das Missoes, in the Rio Grande do Sul state, Brazil. The methods tested had their efficiency improved by increasing the time scale of analysis, keeping the same performance for both locations. The highest and lowest ETo values occurred in December and June, respectively. Most methods underestimated ETo. For any of the time scales Makking and Radiaton FAO24 methods can replace the Penman-Monteith for estimating ETo.

No Estado do Rio Grande do Sul (RS), os Neossolos Litólicos e Neossolos Regolíticos são solos que têm sofrido forte pressão de uso, demandando maior conhecimento sobre sua gênese e mineralogia. O objetivo deste trabalho foi determinar o grau de intemperismo de Neossolos Litólicos e Neossolos Regolíticos, avaliando-se a alteração dos minerais em perfis dispostos em uma climo-litossequência no Planalto do RS, através de técnicas de dissolução química e difração de raios X. Foram identificados dois grupos de solos com graus de alteração distintos. O primeiro é constituído pelos perfis da porção Oeste da climo-litossequência (P1, P2 e P3) e encontra-se no estádio entre a bissialitização e a monossialitização, com predomínio de esmectita com hidroxi-Al entrecamadas (EHE), caulinita e hematita na fração argila. O segundo é representado pelos perfis da porção Leste (P4 e P5), encontrando-se no estádio entre a monossialitização e a ferralitização, com predomínio de caulinita e goethita e presença de gibbsita e EHE na fração argila. Os resultados sugerem maior influência do clima na alteração dos perfis. Os índices ki e kr não foram eficientes em representar a condição de alteração secundária dos perfis de Neossolos.

A serological survey on Ehrlichia canis was conducted among dogs in the central area of the state of Rio Grande do Sul, where the tick Rhipicephalus sanguineus is a common parasite of dogs. Out of a total of 316 dogs attended at the veterinary teaching hospital in the municipality of Santa Maria, only 14 (4.43%) reacted positively to E. canis antigens in the indirect immunofluorescence assay, with the following endpoint titers: 80 (three dogs), 160 (five), 320 (four), 640 (one) and 1280 (one). Like in previous studies in other regions of the state of Rio Grande do Sul, only a very small portion of the dogs in Santa Maria presented antibodies reactive to E. canis, even though canine infestations due to R. sanguineus are very common in this study region. These results contrast with other regions of Brazil, where E. canis is endemic among canine populations, with seropositivity values generally higher than 30%. Genetic differences among the R. sanguineus populations in South America might be implicated in these contrasting results.

Cirrus clouds are an interesting point in the research of the atmosphere due their behavior and the effect on the earth radiation budget. They can affect the atmospheric radiation budget by reflecting the incoming solar radiation and absorbing the outgoing terrestrial radiation. Also, this cloud type is involved in the dehydration of the upper troposphere and lower stratosphere. So, it is interesting to increment the measurements of this type of clouds from the ground. During November and December 2012, through the CHUVA-SUL campaign, measurements with lidar in Santa Maria, Rio Grande do Sul were conducted. The system installed in Santa Maria site (29.8 °S; 53.7 °W, 100 m asl) was a single elastic-backscatter lidar using the wavelength of 532 nm. Some days with cirrus clouds lidar measurements were detected. Four days with presence of cirrus cloud are showed in the present study. These days, 7, 8, 19 and 28 November 2012, was selected due the persistence of cirrus clouds over many hours. The raw retrieval lidar signals and inverted backscatter coefficient profiles were analyzed for the selected days. Base and top height was obtained by analysis of raw signal and backscatter coefficient. Extinction coefficient profiles were obtained by the assumption of the lidar ratio. Cirrus cloud optical depth (COD) values were calculated, from the integration of the extinction coefficient between the base and top altitudes of the cirrus clouds.

This paper has as objective to analyze the foundry work politics made by the Olívio Dutra's government in the state of Rio Grande do Sul-Brazil, being taken into account their guidelines, the dynamics of the political struggle promoted between the social leaders from the rural area and the achieved global results. This government's freshness is related to the fact of it was being sustained and supported by a coalition of left wing parties and by a group of social movements and also by syndical entities of the field, which was decisive in the presentation of an antagonistic program to the neoliberal politics on energy in a national extent. Hence this government became committed in adopting an own foundry work politics, being opposed to the program of market land reform extolled by Cardoso's government, in national wide. Therefore, the results presented along the article demonstrate that in spite of the assumed commitments and, in face of legal, institutional and economical limitations and also its existent politics, the space of the state governments' performance can only be thought about its complemental character on the federal government's actions.

This article focuses on some aspects of the agrarian history of Soledade, a town in the north of the state of Rio Grande do Sul, southern Brazil. Our aim is to understand how this area was in many ways affected by the Land Law of 1850, particularly in economic and social terms. Population growth, arrival of European immigrants and increasing privatization of the commons contributed for the increasing of land prices in the region during the second half of the 19 th century. Understanding this situation as a great opportunity to make money, some landowners, directly or through a colonization company, allotted and sold the land they had previously acquired through the Land Law of 1850
