Abstract: the only breeding record of spartonoica maluroides (d'orbigny & lafresnaye, 1837) for brazil is based on the observation of a fledgling in southern rio grande do sul in january 1976. on 7 december 2005 we discovered a nest containing three nestlings at the southeastern end of lagoa pequena, municipality of pelotas, rio grande do sul. the nest was concealed at the base of a cavity in a spartina densiflora (poaceae) tussock located at the edge of a saltmarsh. the nest was built of fine pieces of dead scirpus olneyi (cyperaceae) and s. densiflora leaves firmly interlaced to the internal leaves of the tussock. live leaves of s. densiflora lining the cavity comprised a substantial part of the nest's architecture, forming most of its upper lateral walls and roof. the lower section was more elaborate, resembling a deep cup and forming a distinct incubation chamber. adults reached the nest's interior through an irregular apical opening amidst the leaves. the nest was 244 mm high and 140 mm wide. the incubation chamber had an external diameter of 138.5 mm, an internal diameter of 79.4 mm and was 86 mm deep. it was lined with fine leaves and white plant fibers. nestlings were five to six days old. a total of 107 neossoptiles restricted to the capital, spinal and alar tracts were recorded in one nestling. the distribution of neossoptiles in the ocular region of s. maluroides forms a distinct pattern which can be typical of furnariidae and related families. two adults attended the nest, bringing small insects to the nestlings and removing fecal sacs. we recorded at least 74 visits to the nest during a ca. 6 h period during an afternoon. the average number of visits per hour was 12.8 ± 1.3. an adult bird spent on average 0.7 ± 0.56 minutes inside the nest attending nestlings. the nest remained unattended on average for 3.61 ± 3.13 minutes. the hour of the day had no influence on the amount of time spent by an adult in the nest or away from it. we returned to the area on 15 decem

Abstract: Afforestation of temperate grasslands with fast-growing trees for industrial pulpwood production is spreading in South America. Despite high afforestation rates resulting from governmental policies that stimulate pulpwood production in grasslands of southern Brazil and Uruguay, the impact of this activity on biodiversity remains to be properly assessed. We used an Impact-Reference study design to evaluate how grassland afforestation affects the composition of grassland bird assemblages. We sampled eucalyptus plantations and neighboring natural grasslands in southern Brazil from 2006-2009, and relied on nested sampling and analysis to separate the effects of afforestation from the natural variability of grasslands. We recorded a significant difference in composition between assemblages from grasslands and tree plantations. Species adapted to open, treeless areas tended to be negatively affected in relation to edge or forest birds in eucalyptus plantations. Afforestation is systematically replacing the bird assemblage of hilltop grasslands by a collection of common edge and forest species that occur in nearby riverine and hillside forests. Although most grassland birds negatively affected by tree plantations are common and widespread, observed and predicted afforestation rates in southeastern South America may result in regional population reductions in the near future. O florestamento de campos temperados com árvores de crescimento rápido para a produ o industrial de celulose está aumentando na América do Sul. Apesar das elevadas taxas de florestamento resultantes de políticas governamentais que estimulam o plantio de árvores para celulose em campos do sul do Brasil e Uruguai, o impacto dessa atividade sobre a biodiversidade ainda carece de avalia o adequada. Utilizamos um delineamento experimental do tipo impacto-referência para avaliar como o florestamento dos campos afeta a composi o da assembleia de aves campestres. Amostramos planta es de eucalipto e campos nativos no sul do Brasil entre 2006-2009 e nos valemos de amostragem e análise aninhada para separar os efeitos do florestamento da variabilidade natural dos campos. Registramos uma diferen a significativa na composi o entre as assembleias de aves do campo e de planta es de eucalipto. Espécies adaptadas a áreas abertas destituídas de árvores foram afetadas negativamente pelo florestamento, ao passo que aves florestais ou de borda de floresta foram favorecidas pela planta o de eucalipto. O florestamento está sistematicamente substituindo a assembleia de aves de campos de topos de morros por

Abstract: El presente estudio tuvo como objetivo analizar las intoxicaciones por saneantes comercializados clandestinamente, reportadas en el Centro de Control de Intoxicaciones del Hospital Universitario Regional de Maringá. Es un estudio cuantitativo, con análisis retrospectivo de registros epidemiológicos de personas intoxicadas por estos agentes, en el período de enero de 2005 a diciembre de 2009. De los 118 casos reportados, la mayoría (74-62,7%) se produjeron en varones, 105 (88,9%) necesitaron de asistencia en unidades de atención de emergencia y hospitalización de alta complejidad, en 14 casos (11,8%) requirieron de Cuidados Intensivos, y se reportaron cinco óbitos, todos por intoxicación intencional. Los resultados demuestran la gravedad y la letalidad de este tipo de intoxicación, sugieren la necesidad de medidas urgentes de fiscalización y control de la Vigilancia Sanitaria, así como de medidas para la educación de los consumidores, haciendo hincapié en el papel educativo de la Enfermería

Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.27108
Abstract: The purpose of this study was to test the factorial validity of the job-related affective well-being scale—the IWP Multi-Affect Indicator. The sample was composed of 1466 police officers and collected through self-report questionnaires. With the objective of validating the factorial structure of the IWP Multi-Affect Indicator, several models were tested using confirmatory factor analysis. The results supported a four-factor structure: anxiety, comfort, depression and enthusiasm, as well as a five-factor structure including the same four factors plus a second-order factor called global affective well-being.

Anais da Sociedade Entomológica do Brasil , 1997, DOI: 10.1590/S0301-80591997000200019
Abstract: the population dynamics of thrips tabaci lind. was evaluated for onion (allium cepa) planted in july, august and september at the ituporanga experimental station, epagri s.a., santa catarina state, brazil, from 1985 to 1988. for each planting date cv. baia periforme, jubileu, empasc 351 sel. crioula and norte 14 were used. severe infestation in all cultivars was observed after mid-october. the population peak of t. tabaci occurred between the end of october and mid-november. cultivars transplanted early tended to escape from high population densities. populations of t. tabaci peaked during bulb formation and decreased thereafter.
Phacoemulsification in hard cataracts: the "chop, trip and free" technique
Gonalves, José Marcos S.;
Arquivos Brasileiros de Oftalmologia , 2004, DOI: 10.1590/S0004-27492004000400008
Abstract: very hard cataracts continue to be a challenge to phacoemulsification due to the difficulty in breaking the nucleus and also in separating the broken nucleus from the adjacent epinucleus. the present technique is the presentation of a surgical maneuver which uses the nagahara chopper and the phaco tip to divide the nucleus (including the epinucleus) as a whole and then emulsify it using little time and not very much phaco power.
Heran?a maldita e política monetária em um modelo de assimetria de informa??o
Gonalves, Carlos E. S.;
Revista Brasileira de Economia , 2005, DOI: 10.1590/S0034-71402005000400003
Abstract: in this paper we use a simple two-period model in which government's preferences are private information to show that a tough monetary stance may help in bringing inflation expectations to lower levels even if the fiscal side of the economy is not in good shape. true, a restrictive monetary policy leads to higher debt levels and potentially to higher expected inflation (fiscal dominance effect). but, on the other hand, it also allows a tough-type government to separate itself from a lax-type one in the eyes of the public (signaling effect). a feature of the model is that inflation and inherited debt are not necessarily positive correlated for all levels of debt. concretely, the high debt levels lula's administration inherited from fhc′s term in office (the so-called "damned heritage") may have helped the former to signal to markets its degree of inflation aversion.
