O regime de metas de inflação no Brasil: uma análise empírica do IPCA

Inflation targeting regime is a monetary policy adopted by several countries in the 1990s, Brazil being among them, which adopted it in 1999 after a currency crisis. With a theoretical framework inspired by the new-classical theory, this regime is adopted by countries attempting to achieve price stability and it brings the prior announcement of a numerical target for inflation as a key feature. The present work aims at discussing the use of IPCA (Consumer Price Index) as a measuring index for Brazil's inflation after briefly explain the theoretical basis of the IT regime.

In-Office dental bleaching efficacy assessment in function of the light exposure regime by digital colometric reflectance spectroscopy

In-office dental bleaching has been subject of several studies. Generally those studies quantify through visual analysis, the shade reduction of the teeth submitted to different bleaching protocols (light sources, bleaching agent concentrations and irradiation time). The objective of this work is the determination of the influence of four irradiation protocols on the obtainment of better aesthetic results using a colorimetric spectrophotometer that quantifies color changes in each situation imposed. Forty bovine incisors were selected in function of similar anatomic characteristics; a concentrated coffee solution was used to stain the teeth. A commercial spectrophotometer was used to measure the color changes during evolution of the experiment (stain and bleaching phases) and the obtained data was analyzed by the ANOVA test. The obtained data showed the evolution of teeth color during the staining period, as well as, the color reduction that each bleaching protocol achieved. Based on our findings it is possible to conclude that bleaching protocols with larger irradiation periods did not showed significant differences when compared with shorter irradiation protocols, in that way the use of protocols with 30 min or more of consecutive irradiation are not clinically justified and also can cause several side effects.

Identidade psicossocial dos adolescentes no regime de internato na Educação Agrícola

Psychosocial Identity of the adolescents in boarding school system in the agricultural education Abstract: This article is the result of a research where we try to study and to understand the psychosocial identity of adolescents undergoing boarding. We discussed the issue of boarding school in literature and notes about adolescence in various psychological approaches. Research strategies were interviews, and focus group reports. We conclude that, even with the difficulties students believe that the promising future can only be achieved through technical training, which would enable them not only to acquire a knowledge, but also as a way to gain access to a better-paying job. A better understanding of the surrounding reality allows us to subsidize various professional institutions also adopt boarding as an option to stay.

Análise dos métodos de descrição do regime eólico e suas aplicações

A energia dos ventos é uma abundante fonte de energia renovável, limpa e disponível em quase todos os lugares. A geração da eletricidade através de fontes alternativas de energia como a eólica e a solar ganha grande importância diante da situação mundial em relação à preservação do meio ambiente e da necessidade de depender menos dos combustíveis fósseis como fontes de energia. No Brasil, algumas medidas precisas de vento, realizadas recentemente em diversos pontos do território nacional, indicam a existência de um imenso potencial eólico ainda não explorado. Para tanto se faz necessário estudos e revisões bibliográficas dos métodos de descrição e dimensionamento do regime eólico bem como as suas aplicações. Para isso foi feito uma análise do recurso eólico disponível na Região de Botucatu, utilizando os principais métodos de análise estatística e de determinação da energia produzida por um aerogerador.

Variáveis morfológicas da cana-de-açúcar em função do regime hídrico durante o desenvolvimento inicial

Water deficit is one of the factors which most limit agriculture yield and growth. Although sugar cane has moderate tolerance to drought, it presents high yield losses under the influence of this abiotic factor. Based on this fact, selection of genotypes tolerant to water stress may represent an alternative for decreasing the amount of water used for irrigation, while keeping or increasing yield. This study was performed in order to evaluate the performance of four sugarcane cultivars during initial development under water stress conditions, by means of morphological variables to select more tolerant genotypes to drought. The experiment was carried out in a greenhouse at the Department of Rural Engineering, College of Agricultural Sciences - UNESP/Botucatu – SP, from November 26th 2010 to April 5th 2011. A total of four sugar cane cultivars were evaluated (RB855453, RB92579, RB965902 and RB965917) under two treatments as follows: control (100% field capacity) and water stress (50% field capacity). Evaluations were performed at 0, 28 and 63 days after treatment application. The following morphological variables were analyzed: plant height, leaf area, leaf length, leaf width, number of green leaves, shoot and root dry matter. The RB855453 and RB92579 cultivars produced more shoot and root dry matter under water stress treatment, while the RB965902 and RB965917 cultivars had lower shoot and root dry matter production under the same conditions. Therefore, the RB855453 and RB 92579 cultivars can be considered tolerant while the RB965902 and RB965917 cultivars can be considered susceptible.

Temporal Differences in the Hydrologic Regime of the Lower Platte River, Nebraska, 1895–2006

In cooperation with the Lower Platte South Natural Resources District for a collaborative study of the cumulative effects of water and channel management practices on stream and riparian ecology, the U.S. Geological Survey (USGS) compiled, analyzed, and summarized hydrologic information from long-term gaging stations on the lower Platte River to determine any significant temporal differences among six discrete periods during 1895-2006 and to interpret any significant changes in relation to changes in climatic conditions or other factors. A subset of 171 examined hydrologic indices (HIs) were selected for use as indices that (1) included most of the variance in the larger set of indices, (2) retained utility as indicators of the streamflow regime, and (3) provided information at spatial and temporal scale(s) that were most indicative of streamflow regime(s). The study included the most downstream station within the central Platte River segment that flowed to the confluence with the Loup River and all four active streamflow-gaging stations (2006) on the lower Platte River main stem extending from the confluence of the Loup River and Platte River to the confluence of the Platte River and Missouri River south of Omaha. The drainage areas of the five streamflow-gaging stations covered four (of eight) climate divisions in Nebraska—division 2 (north central), 3 (northeast), 5 (central), and 6 (east central).

Evolution of extrafloral nectaries: adaptive process and selective regime changes from forest to savanna

Much effort has been devoted to understanding the function of extrafloral nectaries (EFNs) for antplantherbivore interactions. However, the pattern of evolution of such structures throughout the history of plant lineages remains unexplored. In this study, we used empirical knowledge on plant defences mediated by ants as a theoretical framework to test specific hypotheses about the adaptive role of EFNs during plant evolution. Emphasis was given to different processes (neutral or adaptive) and factors (habitat change and trade-offs with new trichomes) that may have affected the evolution of antplant associations. We measured seven EFN quantitative traits in all 105 species included in a well-supported phylogeny of the tribe Bignonieae (Bignoniaceae) and collected field data on antEFN interactions in 32 species. We identified a positive association between ant visitation (a surrogate of ant guarding) and the abundance of EFNs in vegetative plant parts and rejected the hypothesis of phylogenetic conservatism of EFNs, with most traits presenting K-values < 1. Modelling the evolution of EFN traits using maximum likelihood approaches further suggested adaptive evolution, with static-optimum models showing a better fit than purely drift models. In addition, the abundance of EFNs was associated with habitat shifts (with a decrease in the abundance of EFNs from forest to savannas), and a potential trade-off was detected between the abundance of EFNs and estipitate glandular trichomes (i.e. trichomes with sticky secretion). These evolutionary associations suggest divergent selection between species as well as explains K-values < 1. Experimental studies with multiple lineages of forest and savanna taxa may improve our understanding of the role of nectaries in plants. Overall, our results suggest that the evolution of EFNs was likely associated with the adaptive process which probably played an important role in the diversification of this plant group.
