Avaliação da alteração dimensional de modelos obtidos a partir de moldagens com alginato tradicional e outro com desinfetante

The present study aims at evaluating dimensional alteration of stone casts made from impressions with a standard irreversible hydrocolloid and an antimicrobial one. For this, an alginate without disinfectant (Type II Jeltrate) and other containing chlorhexidine (Type II Avagel) were used, which rose by the same regime of treatment: without disinfection; immersion; and spraying. A 1% sodium hypochlorite solution was used for 10 minutes. To obtain the impressions, a perforated impression tray was made from a standard metal model. After molding, the molds were washed in running water for 30 seconds to simulate removal of saliva. Then, with the exception of the control group, these molds were subjected to disinfection treatment. After 10 minutes they were washed again. 60 samples poured with type V special gypsum (Durone) were obtained, that were measured 3 times in a stereomicroscope (SZX12, Olympus) to record the average of dimensional alterations. The disinfection treatment did not bring significant changes in the models obtained from both alginate tested (standard p = 0.7102; with chlorhexidine p = 0.5832). The results showed a statistically significant and additional advantage of the traditional alginate on alginate with chlorhexidine, with respect to dimensional alteration (p < 0.05).

Peias e espartilhos: sátira popular à moda francesa na Primeira República

In the first decades of the Republic, the streets of the main Brazilian capital cities, especially of Rio de Janeiro and Recife, recently urbanized based on the Haussmanian Paris and smiled upon by the fever of cosmopolitanism that invested Europe, women had been used as runways where they could exhibit her imitated or imported models, especially in Paris. The iconography of the time and the advertisements conveyed by magazines and illustrated periodicals, such as the Almanach de Pernambuco and the magazine Kosmos, for instance, form the testimonies of the massive presence of the French in Rio and Recife, owners of stores and maisons, interested in fulfill the demands of the republican public. In spite of the Strong adherence of the Brazilians to the sociability models to the imported from Europe, the less-favored classes, through the popular literature, showed some resistance to these changes in the habits and clothing, especially in the Northeast, where traces of the Catholic and patriarchal moral and mentality were still alive.

Há possibilidades de uma psicologia libertadora na contemporaneidade?

This article aims to generate reflections on the current Brazilian educational situation and briefly discuss the changing paradigms of post-modernity that affect it. Today's education will be discussed and questioned from the mold of traditional education institution (postulated analyzed and criticized by Paulo Freire and still present in our society) and soon to be opposed to the proposal from liberating pedagogy (teaching theoretical foundations that focus on developing of a social nature of no alienation and contribution to the formation of critical subjects of their own destiny, comes in trying to transform the current education, reinforced by the individualistic and consumerist bonds in a democratic education (teachers and students in a relationship horizontal) facing the current questions of social values.

Annual, seasonal and spatial abundance of the seabob shrimp Xiphopenaeus kroyeri (Decapoda, Penaeidae) off the Southeastern coast of Brazil

We investigated the influence of environmental factors in spatial and temporal distribution of the seabob shrimp Xiphopenaeus kroyeri in Santos Bay and São Vicente Estuary, state of São Paulo, Brazil. Monthly samples were obtained, from May 2008 through April 2010, from four locations in the estuary and four in the bay. No individual was collected in the estuary and this was attributed to the low salinity means recorded in this environment. We collected 109,153 individuals in the bay and there was no difference in abundance between the two years comprised by the study period. The similarity in spatial distribution can be related to sediment grain size that in all sampling locations showed great amount of very fine sand. The largest amount of reproductive females was obtained in early 2010, when temperature was high, and this could have increased the juvenile recruitment in April 2010. According to our results, the distribution of X. kroyeri in the study area is influenced by temperature, which is related to reproduction, and salinity, limiting the entrance of individuals in the estuarine region.

Tratamentos pré-germinativos e substratos na emergência de sementes e qualidade de mudas de pinhão manso (Jatropha curcas L.)

The physic nut can be propagated asexually or sexually. Using cuttings have been earlier yield and more fidelity characteristics of the parent plant. However, there is less initial vegetative growth. The seeds from the plants have increased genetic variability, are more vigorous and begin production later. To get quality changes, the substrate is an important factor. With that the objective was to taste pre-germinated treatments and different substrate on seeds emergence and quality physic nut seedlings. The experimental design was completely randomized, in factorial scheme 6 x 3 (pre-germinated treatments x substrate), 18 treatments and 4 repetition, 8 seeds to each repetition. It was evaluated six pre-germination treatments: T1: witness (without treatments); T2: water immersion for 12 hours; T3: water immersion for 24 hours; T4: mechanical scarification; T5: mechanical scarification + water immersion for 12 hours; T6: mechanical scarification + water immersion for 24 hours, using as substrate: commercial, expanded vermiculite and sand washed. The mechanical scarification was realized opposite the micropyle using sandpaper n. 60. After the pre-germination treatments, the seeds were emergence in plastic cups (200mL) with substrates. We evaluated the characteristics: percentage, beginning and emergence speed index, mean length of plant, diameter of plant stem, SPAD index, fresh and dry shoot and root. The results showed that in seeds of Jatropha do not need pre-germinative treatments; and the use of commercial substrate showed seedling development.
