1. Proposal process management at the plant operation applied to the generating unit shutdown process of Itaipu Binacional
Resumo A Gestão de Processos é um modelo que possibilita a gestão funcional dos processos internos, transversais ou não, de uma organização. Possibilita o controle adequado dos recursos, mapeamento das funções e atividades, e tem por fim a melhoria dos resultados com sustentabilidade. Alinhada a tais objetivos, à Área de Operação da Usina Itaipu

2. Extreme drought events and the sustainability of fish farming in net cages in reservoirs of the semi-arid northeastern region in Brazil
Resumo Os reservatórios desempenham funções importantes no desenvolvimento socioeconômico local, sendo particularmente relevantes em países em desenvolvimento. Entre seus diversos usos a criação de tilápia do Nilo (Oreochromis niloticus) em tanques-rede é um dos que mais cresce, principalmente para sustentar a demanda crescente por pescado. No semi�

3. Professionalizing bureaucracy and building state capacities: are there unequal advances in Brazilian public administration?
Resumo Este artigo contribui para a discussão sobre a administração pública no Brasil examinando as diferenças entre as quatro funções estatais — funções básicas, bem-estar, infraestrutura e desenvolvimento e funções emergentes — com base nos cargos e nas carreiras dos servidores públicos. Os dados foram coletados em 2014, por meio de pesqui

4. The Generalized Odd Lindley-G Family: Properties and Applications
Abstract: We introduce a new class of continuous distributions called the generalized odd Lindley-G family. Four special models of the new family are provided. Some explicit expressions for the quantile and generating functions, ordinary and incomplete moments, order statistics and Rényi and Shannon entropies are derived. The maximum likelihood method is us

5. A new model for describing remission times: the generalized beta-generated Lindley distribution
New generators are required to define wider distributions for modeling real data in survival analysis. To that end we introduce the four-parameter generalized beta-generated Lindley distribution. It has explicit expressions for the ordinary and incomplete moments, mean deviations, generating and quantile functions. We propose a maximum likelihood procedure t

6. Development of Alternative Methods for Determining Soil Organic Matter
ABSTRACT Soil organic matter (SOM) is important to fertility, since it performs several functions such as cycling, water and nutrient retention and soil aggregation, in addition to being an energy requirement for biological activity. This study proposes new trends to the Embrapa, Walkley-Black, and Mebius methods that allowed the determination of SOM by spec

7. Estimating the average length of hospitalization due to pneumonia: a fuzzy approach
Exposure to air pollutants is associated with hospitalizations due to pneumonia in children. We hypothesized the length of hospitalization due to pneumonia may be dependent on air pollutant concentrations. Therefore, we built a computational model using fuzzy logic tools to predict the mean time of hospitalization due to pneumonia in children living in São

8. A Mixed-Integer convex formulation for production optimization of gas-lifted oil fields with routing and pressure constraints
Production optimization of gas-lifted oil fields under facility, routing, and pressure constraints has attracted the attention of researchers and practitioners for its scientific challenges and economic impact. The available methods fall into one of two categories: nonlinear or piecewise-linear approaches. The nonlinear methods optimize simulation models dir

9. Um estudo sobre o papel de medidas de similaridade em visualização de coleções de documentos / A study on the role of similarity measures in visual text analytics
Information visualization techniques, such as similarity based point placement, are used for generating of visual data representation that evidence some patterns. These techniques are sensitive to data quality, which depends of a very influential preprocessing step. This step involves cleaning the text and in some cases, detecting terms and their weights, as

10. Demonstrações bijetivas em partições / Bijectives demonstrations in partitions
This work presents some results about partitions of integers numbers and their importance in the history of Mathematics and in the Theory of the Numbers. To find bijective demonstrations in partitions it is not easy. But, after finding them, to understand and to prove some Identities of Partitions becomes agreeable and easy. This work intends to be didatic a

11. An FET-based microwave active circuit with dual-band negative group delay
Recent studies proved that certain electronic active circuits are capable to exhibit simultaneously a negative group delay (NGD) and amplification in microwave frequency bands. One of the simplest topologies generating this counterintuitive NGD function effect is formed by a series RLC-network in cascade with a transistor. By using this cell, similar to the

12. Expressed sequence tag analysis of khat (Catha edulis) provides a putative molecular biochemical basis for the biosynthesis of phenylpropylamino alkaloids
Khat (Catha edulis Forsk.) is a flowering perennial shrub cultivated for its neurostimulant properties resulting mainly from the occurrence of (S)-cathinone in young leaves. The biosynthesis of (S)-cathinone and the related phenylpropylamino alkaloids (1S,2S)-cathine and (1R,2S)-norephedrine is not well characterized in plants. We prepared a cDNA library fro
