Ocorrência do subtipo B do vírus da imunodeficiência felina em gatos domésticos da região sul do estado do Rio Grande do Sul, Brasil

In Brazil there are few studies on the occurrence of the feline immunodeficiency virus (FIV) infection and its subtypes, which are essential for the development of vaccines and new diagnostic tests. The present study investigated the occurrence of the FIV infection between 2010 and 2011 in domestic cats submitted to medical attendance in the city of Pelotas and nearby area. Total blood samples of seventy cats, suspected (28) or not (42) of infection by FIV were analyzed by nested PCR in order to perform a diagnosis. The results pointed to a FIV infection frequency of 15.7% (11/70) and the analysis of the risk factors related to infection (sex, age and clinical condition) evidenced a greater occurrence in cats up to 10 years of age with chronic and recurrent infections. Eight samples found positive by nested PCR were submitted to DNA sequencing indicating that only the subtype B was detected in the studied region.

Identificação da dinâmica espaço-temporal para estimar área cultivada de soja a partir de imagens MODIS no Rio Grande do Sul

The objective of this study was to define a method for estimating soybean crop area in the Northern Rio Grande do Sul state (Brazil). Overall, six different remote sensing methods were proposed based on spectral-temporal profile and minimum and maximum values of NDVI/MODIS related to the stages of sowing, maximum development and harvesting of soybean areas. The resulting estimates were compared to official crop area data provided by the Brazilian government, using statistical analysis and the fuzzy similarity method. The performance of each method depended on information such as crop size, type of crop management, and sowing/harvesting dates. Regression coefficients of determination and fuzzy agreement values were above 0.8 and 0.45, respectively, for all methods. For operational monitoring of soybean crop area, the empirical threshold applied to the image difference with inclusion of harvest image method was the most effective, producing estimates that matched closely the official data. For spatial analysis the application of multitemporal images classification method is recommended that generated a map of better quality. The efficiency of these methods should be evaluated in the areas of soybean expansion in the state.

A new hairy Leptogium (section Mallotium) from Rio Grande do Sul State, Brazil

The hairs of Leptogium species are complex structures which determine taxonomic groups within the section Mallotium. The hairs composed of cylindrical cells can be short and, when present on the surface, give origin to glass-or velvet-like hairs. Leptogium involutum, collected in Southern Brazil, a new species with velvet-like hairs is described herewith.

Fragilizaçõa financeira dos estados e a crise federativa: uma análise a partir do ajuste fiscal dos estados de São Paulo e Rio Grande do Sul

O objetivo deste trabalho é avaliar a situação financeira dos estados de São Paulo e Rio Grande do Sul após a renegociação da dívida financeira com o governo federal. A renegociação da dívida foi efetivada mediante a aprovação de um Programa de Ajuste Fiscal com metas periodicamente reavaliadas. É realizada uma contextualização histórica da economia brasileira e da situação dos estados brasileiros. Em seguida, é estudado o Programa de Ajuste Fiscal do Estado de São Paulo, e o Programa de Ajuste Fiscal do Estado do Rio Grande do Sul. Por fim, são realizadas algumas considerações acerca dos Programas desenvolvidos e realizados pelos Estados

Zaira de Bittencourt Martins: pioneira da psicanálise de crianças no Rio Grande do Sul

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.

Fenologia de Caryocar brasiliense Camb. (Caryocaraceae) no Alto Rio Grande, sul de Minas Gerais

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