1. AvaliaÃÃo da DistribuiÃÃo das Cotas-Parte do ICMS Devidas aos MunicÃpios Cearenses: cenÃrios alternativos / Evaluation of the Distribution of shares in the GST owed to the municipalities CearÃ: alternative scenarios
This study aims to evaluate the change in 2007 on the criteria for transfer of shares in the ICMS to municipalities in CearÃ. For both, there will be a comparative analysis between the previous criteria - based on spending - and current - which qualifies through the performance in the sectors education, health and environment, and quantifies the VAF. Thus,

2. Uma proposta de construção de índice invertido para recuperação de imagens baseada em conteúdo
This work shows an approach to construct an inverted index for Content-Based Image Retrieval. The objective is to speed up the process of querying without loss of quality in the result. To evaluate the effectiveness of the proposal, two systems for retrieval of images were developed. The first system was used as a basis for comparison. It uses techniques for

3. Interpolation techniques evaluation to estimate volume in cloned forest Eucalyptus sp. / Avaliação do uso de técnicas de interpolação para estimativa de volume em florestas clonais de Eucalyptus sp.
The Knowledge about the forest stock is an important tool to support the short, medium and long term planning. In each stand the stock is obtained through the forest inventory. This work aimed to apply geostatistics concepts that get benefits from the spatial dependence of certain variables to estimate the volume at non sampled points. For this study, it wer

4. Pressão arterial e manipulação tubular renal de sodio em um modelo de septicemia em ratos
Acute renal failure is a frequent complication in septic patients associated with a high mortality rate. An important characteristic is a decrease in glomerular filtration rate, which is even present in situations where renal blood flow has been maintained. Prevailing hypothesis on the pathogenesis of renal failure suggest an inappropriate and uncontrolled r

5. Temporal comparisons in bacterial chemotaxis.
Responses of tethered cells of Escherichia coli to impulse, step, exponential-ramp or exponentiated sine-wave stimuli are internally consistent, provided that allowance is made for the nonlinear effect of thresholds. This result confirms that wild-type cells exposed to stimuli in the physiological range make short-term temporal comparisons extending 4 sec in

6. Responses of macaque ganglion cells to the relative phase of heterochromatically modulated lights.
1. We measured the response of macaque ganglion cells to sinusoidally modulated red and green lights as the relative phase, theta, of the lights was varied. 2. At low frequencies, red-green ganglion cells of the parvocellular (PC-) pathway with opponent inputs from middle-wavelength sensitive (M-) and long-wavelength sensitive (L-) cones were minimally sensi

7. The net of life: Reconstructing the microbial phylogenetic network
It has previously been suggested that the phylogeny of microbial species might be better described as a network containing vertical and horizontal gene transfer (HGT) events. Yet, all phylogenetic reconstructions so far have presented microbial trees rather than networks. Here, we present a first attempt to reconstruct such an evolutionary network, which we
