1. Generalised cascades
In this manuscript we give thought to the aftermath on the stable probability density function when standard multiplicative cascades are generalised cascades based on the q-product of Borges that emerged in the context of non-extensive statistical mechanics.

2. Introducing the q-Theil index
Starting from the idea of Tsallis on non-extensive statistical mechanics and the q-entropy notion, we recall the Theil index Th and transform it into the Th q index. Both indices can be used to map onto themselves any time series in a non linear way. We develop an application of the Th q to the GDP evolution of 20 rich countries in the time interval [1950 -2

3. Um Procedimento analítico para o cálculo das integrais bi-eletrônicas em métodos de mecânica quântica molecular
The present work develops an alternative methodology (q-Integral method) to evaluate the two-electron integrals which appear in ab initio molecular quantum mechanical calculations. The q-Integral method is based on the q-Exponential function, which comes from the Tsallis non-extensive statistics mechanics. The advantage of this procedure is that the CPU time

4. HIGH-FREQUENCY DYNAMICS OF THE BRAZILIAN STOCK MARKET / DINÂMICA INTRADIÁRIA DO MERCADO DE AÇÕES BRASILEIRO
A modelagem do mercado financeiro requer uma descrição completa da estatística dos preços assim como de sua dinâmica. Analisamos as flutuações de preço do mercado de ações brasileiro (IBOVESPA) em escala de tempo intradiária, no período 2002-2004, considerando distribuições q- Gaussianas P(q) (x,t) provenientes da estatística não-extensiva de

5. Um estudo sobre características do subdomínio inercial da turbulência desenvolvida em escoamento acima e dentro da copa da Floresta Amazônica de terra firme e acima do Pantanal Matogrossense / An study about statistical characteristics of inertial subrange of developed turbulence in flows above and below of Amazonia Forest canopy and above Pantanal Matogrossense
In this work turbulent data measured in two micrometeorologicaly different regions, sampled at 60 Hz, were used. The first data set was obtained at a tower in the Rebio-Jaru Reserve, during an intensive campaign of the Large Scale Biosphere Atmosphere Experiment in Amazonia - (LBA) in 1999. The second set was obtained in the Pantanal Matogrossense, Interdisc

6. Resting energy expenditure and oxygen cost of breathing in patients with cystic fibrosis.
BACKGROUND: Resting energy expenditure (REE) is often increased and may contribute towards energy imbalance in patients with cystic fibrosis. Several mechanisms may lead to increased REE including the gene defect, the effect of chronic infection, and abnormal pulmonary mechanics. Increased oxygen cost of breathing (OCB) has been demonstrated in patients with
