O regime de metas inflacion��rias e sua adequa����o �� economia brasileira

The Inflation Targeting Regime was adopted in Brazil in 1999 and it aims at maintaining the price level in the interval set by the government. For such reason, the Central Bank makes use of variations in the interest rate, which causes the cost of the credit to be more expensive, reducing the investments, the jobs and, concomitantly, the inflation. Being aware that the country is subject to sudden reversals of the international capital flows which results in exchange rate and price instability, an econometric analysis of the adequation of the targerting regime to the Brazilian economy, especially concerned with the index price that is used as the parameter for the inflation calculus, is proposed

Determina����o da cr��tica raz��o esfor��o pausa (e:pcrit) em uchi-komi no jud��, utilizando deltas de varia����o de freq����ncia card��aca e escala de percep����o de esfor��o de Borg

O presente estudo objetivou verificar a validade de um protocolo de teste aer��bio espec��fico do jud�� (t��cnica ipon-seoi-nague), n��o exaustivo, adaptado do m��todo de CHASSAIN (1986), utilizando deltas de varia����es da escala de percep����o de Borg e da freq����ncia card��aca em atletas bem treinados. O teste adaptado ao jud�� constituiu de quatro s��ries de exerc��cio com dois esfor��os iguais (duplos) de 180 segundos com um intervalo de 90 segundos entre eles. As s��ries de exerc��cios foram realizadas em dias consecutivos. As intensidades dos testes duplos foram de 85%, 95%,105% e 115% do lactato m��nimo para cada participante. Este trabalho utilizou a t��cnica ipon-seoi-nague, sendo que as raz��es esfor��o-pausa foram espec��ficas para cada atleta, e correspondem ��s intensidades de exerc��cio propostas pelo protocolo de Chassain (1986). A escala de percep����o de esfor��o de Borg foi mostrada ao final do primeiro e do segundo esfor��os, em cada uma das s��ries, para que o atleta determinasse o n��vel de cansa��o. Para an��lise da freq����ncia card��aca foi utilizado um freq��enc��metro, Polar Vantage NV, obtendo freq����ncia card��aca concomitantemente a escala de Borg, ao final de bloco de esfor��o. Dessa maneira, foram obtidos dois deltas de varia����es entre o primeiro e o segundo esfor��os, para escala de percep����o de Borg (��BORG) e FC (��FC). Uma vez que foram utilizadas quatro intensidades, foi poss��vel determinar quatro ��BORG e quatro ��FC. Assim, a partir de duas regress��es lineares (uma para o Borg e outra para a FC), foi poss��vel determinar as raz��es esfor��o:pausas cr��ticas do exerc��cio na t��cnica espec��fica do Jud��, a partir da determina����o das intensidades nas quais a varia����o de Borg e da FC foi igual a zero (��BORG=0 e ��FC=0). Para validar esses procedimentos adaptados de Chassain (1986) ao Jud��, foi realizado o teste de Lactato M��nimo Adaptado, conforme sugerido por Azevedo (2002).

Valida����o de uma escala colorida de esfor��o percebido para adultas jovens e idosas em caminhada na esteira

The perceived exertion has been used for the intensity control and exercise prescription. Among the various scales that estimate the perceived exertion, the Borg���s RPE scale is one of the best known. However, for populations with low levels of schooling or with visual difficulties such as the elderly, the application of these scales becomes more difficult. In previous studies, a color scale of perceived exertion was developed to aim for assistance in application of the scale and interpretation of perceived exertion. This scale showed high correlation with the Borg���s scale and proved to be valid to estimate the perceived exertion. Thereby, the aim of this study was to assess the validity of the color scale of perceived exertion to measure the perceived exertion in adult women of different ages. Participated in the study 12 young adult women with age of 21,7 �� 1,5 years old, and 10 elderly women with age of 60,3 �� 3,5 years old. The participants were submitted to an incremental exercise of treadmill walking with stages of 2 minutes duration. The inicial load was 5,5 km/h and inclination of 6% for young women and 2% for elderly women, both with 2% increments at each stage completed, without changing the speed. Heart rate and oxygen comsuption responses were determined at the 30 finals seconds of each stage. At the 60 finals seconds of each stage participants indicated the perceived exertion for the overall body, for the legs and for the chest, primarily in the color scale and following in the tradicional Borg���s scale. The analysis of variance for repeated measures was used to assess the effect of different loads on the perceived exertion and physiological responses. The correlations betwen physiological variables, color scale and Borg���s scale were analyzed in group and individually. In all analysis the significance...(Complete abstract click electronic access below)

Avalia����o da auto-sufici��ncia energ��tica de reatores anaer��bicos aplicados ao tratamento de res��duos de uma cervejaria em escala piloto

This project aimed to analyze the feasibility of the methane yield associated to the anaerobic digestion of brewery residues, checking whether the energetic balance of the system is favorable. The methane yield efficiency was calculated for the parameters of two papers that treated solids with a particle-size <1mm. Theses solids are not degraded in conventional treatment systems. Calculations were based in the reactions of anaerobic degradation of the macromolecules that compose brewery residues, considering the theoretical production and the effective production of methane. The results were 50.44% and 52.86%. Regarding to the energy balance of the anaerobic treatment, we noted the high influence of the selection and operating regime of electrical equipment over the potential energy. The best situation, in which the energetic self-sufficiency was reached, was observed when using the mixer under an intermittent regime (1min/h), without employing the heating recirculator, for the maximum organic loading of 4.0 gVS/L.day (days 248-258). In this case, the system would generate an amount of energy equal to 0.0356 kWh/day, able to overcome the energy required by the equipment in about 6.5 times. Moreover, we also noted the interference of the application of different solid loadings in the reactors, once the application of the higher organic load generated 5 times more energy than the application of the smaller one

Metas de infla����o no Brasil (1999-2012): uma an��lise institucional

The paper shows the advantages and handicaps of implementing an inflation target (IT) regime, from post-keynesian and institutional stances. It is post-keynesian as long as it does not perceive any benefit in the mainstream split between monetary and fiscal policies. And it is institutional insofar as it shows there are several ways of implementing a policy, such that the chosen one is determined by historical factors, as illustrated by the Brazilian case. Thus, one could even support IT policies if their targets were seen just as ���focusing devices��� guiding economic policies, but also regarding with due attention other targets, as, in the short run, output growth and employment and, in the long run, technology and human development. Therefore, an IT is not necessary, although it can be admitted, mainly if the target is hidden from the public, in order to increase the flexibility of the central bank.

O regime de metas de infla����o no Brasil: uma an��lise emp��rica 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.

Correspond��ncia de cor de diferentes marcas e sistemas de resina c omposta em rela����o �� escala vita classical

The objective of this study was to compare different resins and determine their matching color with Vita shade, also investigating the possibility of substitution among them and the correlation between the visual and spectrophotometry methods of color selection. The composite resin Tetric N-Ceram�� shade A1 was used as light-control and color A4 as dark-control. For each material were prepared five 10 x 2 mm disks. Analyses were performed in a metamerism box by volunteers who ordered the specimens from the lightest to the darkest. The spectrophotometry was carried out using the spectrophotometer Vita Easyshade��. ���E values were subjected to analysis of variance with 5% significance level. The Fisher exact test showed that there was no color match among the materials and the reference Vita shade. The possibility of substitution among the composites could not be established. The two methods are able to correctly differentiate the control resin A4 as distinct from the other resins shade A2.

Adapta����o transcultural Brasil-Portugal da escala Brief Cope para estudantes do ensino superior

The aim of this study was to adapt the BriefCOPE Inventory for Portuguese-speaking university students. We evaluate the Portuguese BriefCOPE psychometrics qualities and estimated the BriefCOPE factorial invariance in Brazil and Portugal. The data collected from a sample of 1573 students of both nationalities did confirm the 14-factor structure of the BriefCOPE and showed both factorial, convergent and discriminant related validities. However, the factor model did not show invariance across countries indicating that the use of the Portuguese version of the BriefCOPE cannot be bailed for comparisons of scores of inter-countries' student coping.
