1. Doses and application times of trinexapac-ethyl in upland rice
ABSTRACT The use of growth regulators as a technique that can reduce plant height and thus strengthen stalks, which may be an option to eliminate or reduce plant lodging, thereby avoiding crop loss. However, there is a lack of information on the subject. The purpose of this study was to evaluate the effect of the dose (0; 37.5; 75.0; 112.5 e 150.0 g ha-1 act

2. Pré-Despacho de um Sistema Hidrotérmico com Manobras e Restrições de Rampa
RESUMO. Os métodos de pontos interiores primais-duais foram utilizados para o problema de minimização do custo de operação do pré-despacho DC de um sistema de potência hidroelétrico e hidrotérmico onde ocorrem adicionalmente manobras programadas e restrições de rampa. Com a variação da demanda, se faz necessário realizar algumas manobras progra

3. FROM REVELRY TO PERFORMANCE: BIOPOWER IN THE ORGANIZATION OF THE CARNIVAL OF OLINDA
RESUMO Objetivo: O presente estudo busca compreender como o biopoder se manifesta na organização do Carnaval de Olinda. Para tanto, o Carnaval é estudado como uma complexa organização, compreendendo esse conceito para além das organizações formais, e o poder é estudado sob a perspectiva foucaultiana, que constitui a lente teórica desta investigaç

4. Study and Assessment of the Efficiency of the Cocoa Bark Extracted from the Theobroma Cacao as an Inhibitor of the Corrosion of Carbon Steel in Substitution of Benzotriazole
Corrosion represents high losses to the economy, therefore, researches on the minimization of its damages in materials, mainly the metallic ones, are necessary. Among the various alternatives of protection against corrosion, there is the application of corrosion inhibitors that can minimize or even stop the corrosive process of metallic materials. However, a

5. Effect of desulfurization of diesel and its blends with biodiesel on metallic contact
The current environmental scenario has required changes in fuel nature, in order to minimize the harmful effects caused by sulfur in diesel. However, reductions in sulfur content promote loss of its lubricity and consequently wear in the injection system of the diesel engine. This study aimed to investigate the influence of sulfur minimization on fuel lubric

6. Reconfiguração e Alocação Ótima de Geração Distribuída em Sistemas de Energia Elétrica / OPTIMAL RECONFIGURATION AND DISTRIBUTED GENERATION ALLOCATION IN ELECTRIC POWER SYSTEMS
This work presents a methodology for optimal reconfiguration and optimal distributed generation allocation aiming to minimize technical energy losses in electric power distribution systems. The proposed methodology includes two step by step heuristic algorithms, based on sensitivity indexes, one for the reconfiguration and the other for the distributed gener

7. Change in genetic size of small-closed populations: lessons from a domestic mammal population
The aim of this study was to monitor changes in genetic size of a small-closed population of Iranian Zandi sheep, by using pedigree information from animals born between 1991 and 2005. The genetic size was assessed by using measures based on the probability of identity-by-descend of genes (coancestry, f, and effective population size, Ne), as well as measure

8. Optimal reconfiguration of the electric power distribution systems using a modified ant colony system algorithm / Reconfiguração ótima de sistemas de distribuição de energia elétrica baseado no comportamento de colônias de formigas
O objetivo deste trabalho é apresentar uma nova abordagem para obtenção de configurações para sistemas de distribuição de energia elétrica com o intuito de minimizar o valor de perdas ativas sem violar as restrições operacionais. Para isso, considera-se que os sistemas de distribuição estão operando em regime permanente e que suas fases estão e

9. Otimização da Produção de Enzimas por Aspergillus niger em Fermentação em Estado Sólido
Brazil is one of the main producer countries of rice and passion fruit. The production of these foods have generated a large amount of wastes which could represent serious problems with the final disposal and cause economic losses from misuse of biomass. The enviroment pollution and loss of economic value from this biomass can be reduced by using this materi

10. Desenvolvimento e validação de metodologia analítica para determinação de hidrocarbonetos policíclicos aromáticos (HPAS) em sedimentos. Avaliação da represa do Parque Pedroso, Santo André, SP / Development and validation of analytical methodology for determination of polycyclic aromatic hydrocarbons (PAHs) in sediments. Assessment of Pedroso Park Dam, Santo André, SP
The polycyclic aromatic hydrocarbons (PAHs), by being considered persistent contaminants, by their ubiquity in the environment and by the recognition of their genotoxicity, have stimulated research activities in order to determine and evaluate their sources, transport, processing, biological effects and accumulation in compartments of aquatic and terrestrial

11. AlocaÃÃo de recursos com justiÃa: uma aplicaÃÃo de jogos cooperativos em redes de computadores
This work presents a methology for applying cooperative game theory concepts for solving the bandwidth allocation problem within differentiated traffic profiles for Internet applications. The multi-service networks scenario is explored as an operational network example for fair bandwidth sharing mechanisms. This operational network uses mechanisms based on s

12. Comportamento de filtros rápidos de camada profunda no tratamento de águas de abastecimento mediante o emprego de polímeros como auxiliares de filtração. / Behavior of deep bed rapid filters treating public water supplies through the use of polymers as filter aids.
The project was to evaluate the use of anionic and cationic polymers of different molecular weights as filter aids to treat drinking water treatment of surface water sources with high degree of eutrophication, particularly with regard to particulate matter removal optimization and head loss rate minimization. The experimental apparatus was composed of four p
