1. Cumulative changes in water quality caused by six cascading hydroelectric dams on the Jauru River, tributary of the Pantanal floodplain
RESUMO O presente estudo avalia as alterações na qualidade da água, individuais e cumulativas, de seis hidrelétricas (HPP) em cascata, que estão em operação no Rio Jauru, um afluente direto do rio Paraguai, o principal rio da planície de inundação do Pantanal, além de apresentar uma caracterização geral da qualidade da água do Rio Jauru. A qua

2. Evaluation of Crocins in Cheeses Made with Saffron by UHPLC
Saffron is a widespread consumed spice with potential health promoting compounds. In dairy technologies it is often used to enhance color and flavor of cheeses, so it would be recommended to know the content of saffron functional compounds in cheese made with this spice, as they could still have potential bioactivity. For this purpose, an UHPLC (ultra high p

3. Genesis and Classification of Sodic Soils in the Northern Pantanal
ABSTRACT The simultaneous occurrence of high levels of exchangeable sodium percentage (ESP) and alkalinity in soils imposes restrictions on plant development and affects physical properties such as porosity, bulk density, permeability, and hydraulic conductivity. Although sodic soils are frequent in the flood plain of the São Lourenço River, northern Panta

4. Genesis and Classification of Soils from Subtropical Mountain Regions of Southern Brazil
ABSTRACT Soils formed in high mountainous regions in southern Brazil are characterized by great accumulation of organic matter (OM) in the surface horizons and variation in the degree of development. We hypothesized that soil properties and genesis are influenced by the interaction of parent materials and climate factors, which differ depending on the locati

5. Microbial dynamics during azo dye degradation in a UASB reactor supplied with yeast extract
The present work aimed to investigate the microbial dynamics during the anaerobic treatment of the azo dye blue HRFL in bench scale upflow anaerobic sludge bed (UASB) reactor operated at ambient temperature. Sludge samples were collected under distinct operational phases, when the reactor were stable (low variation of color removal), to assess the effect of

6. Macroecologia do zooplâncton continental: padrões latitudinais e componentes locais e regionais na determinação da diversidade global / Macroecology of continental zooplankton: latitudinal patterns and local and regional components in determining global diversity
One of the oldest and best known global biological patterns in ecology is the latitudinal gradient of richness, characterized by a decrease in the number of species from Equator toward the poles. Several hypotheses, even today, attempt to explain the variation that occurs in the pattern of diversity of many animal and plants. Despite the advances that have b

7. Uma avaliação sobre características espaço-temporais baseadas em invariantes de cor para reconhecimento de ações
Local spatiotemporal feature has been proved to be a powerful tool to represent latent patterns of moving objects in video scenes. In particular, recognition of human actions has been the principal focus for various growing applications, including video indexing, content-based video retrieval, video summarization, filtering of unwanted content, rating of mov

8. Tratamento de água para consumo humano de reservatório eutrofizado através de pré e interoxidação, adsorção em carvão ativado e dupla filtração / Drinking water treatment of eutrophic reservoir by pre and interoxidation, activated carbon adsorption and double filtration
Disordered basins occupation provoked acceleration of eutrophication, which besides purely aesthetic and landscaping problems, results in occurrence of high phytoplankton densities with potentially toxic cyanobacteria dominance. Alongside physical aging and consequent deterioration of installations, usual treatment technologies do not provide adequate condit

9. Fast two-step segmentation of natural color scenes using hierarchical region-growing and a color-gradient network
We present evaluation results with focus on combined image and efficiency performance of the Gradient Network Method to segment color images, especially images showing outdoor scenes. A brief review of the techniques, Gradient Network Method and Color Structure Code, is also presented. Different region-growing segmentation results are compared against ground

10. Entre Mendel e Lamarck : o discurso acadêmico sobre raça e polêmica em torno do gradiente de cor. Brasil (1990-2005)
O presente estudo estabelece como proposta de trabalho a realização de uma leitura da literatura acadêmica do Brasil relacionada à temática da raça. A intenção é examinar a presença de narrativas de domínio comum, especialmente para o período 1990- 2005, e sua relação com outras narrativas. Para alcançar esse objetivo, o trabalho foi dividido

11. The weighted gradient: a color image gradient applied to morphological segmentation
This paper proposes a method for color gradient computation applied to morphological segmentation of color images. The weighted gradient (with weights estimated automatically), proposed in this paper, applied in conjunction with the watershed from markers technique, provides excelent segmentation results, according to a subjective visual criterion. The weigh

12. Geographic patterns of the fruit traits from Atlantic forest: environmental and ecological relationships of the dispersal modes / Padrões geográficos das síndromes de dispersão e características dos frutos de espécies arbustivo-arbóreas em comunidades vegetais da Mata Atlântica
Fruits with seeds dispersed by vertebrates are very frequent in tropical forests. However, there is a great variation in the proportion of zoochoric fruits when different communities are compared. Atlantic forest might have between its species, similar proportion of biotic dispersal modes comparing with other tropical forest communities but, its communities
