1. ESTUDO DE UM REATOR SOLAR HÍBRIDO PARA CURA ACELERADA DO CONCRETO EM ÁGUA MORNA. / STUDY OF A HYBRID SOLAR REACTOR FOR ACCELERATED CURING OF CONCRETE IN WARM WATER.
The Portland cement concrete material is the most consumed after the water worldwide due to their versatility molding, strength and durability as a structural material. The curing is the procedure that aims to keep the concrete saturated with water in their early ages and it is essential to ensure the reactions of cement hydration, promoting its consolidatio

2. Measurements of the neutron spectrum energy in the IPEN/MB-01 reactor core
This work presents the results of neutron spectrum measurements at central position of the IPEN/MB-01 reactor core. For this purpose has been used several activation foils (Au, Sc, U, Mg, Ti, Ni, and In Foils) that have been irradiated at central position of the reactor core (standard rectangular configuration 28 × 26 fuel rods) in the maximum power level (

3. Modelagem e análise de desempenho transitório e dinâmico de compensadores estáticos de reativos utilizando reatores saturados
A crescente demanda de energia nos sistemas elétricos tem resultado em dificuldades crescentes na sua operação. Isso tem levado os especialistas a tratar o controle da potência reativa e da tensão com mais rigor, principalmente em sistemas elétricos com características radiais conciliados com cargas sazonais. Para isso, dentre as várias possibilidade

4. Determinação dos parâmetros de compensadores estáticos de reativos e estratégia para o projeto otimizado de reatores saturados
Due to the increasing demand of consumption, the electric energy systems have faced, in the current times, problems with its operation, being the voltage control one of the most relevant matters. To provide means to solve such problems, the use of static compensators has emerged, amongst others, as a classical alternative. Although the modern solutions are m

7. Kinetics of helminth eggs inactivation in water and digested sludges by saturated steam produced with methane from anaerobic digestors. / Inativação térmica de ovos de helmintos em água e em biossólidos digeridos: cinética em reator batelada e modelagem matemática em reator tubular.
Biological sludge can be a valuable resource for agricultural soil conditioning. However, an important obstacle for its use is the usual presence of pathogenic organisms, capable of disease dissemination. The main occurring pathogens are virus, bacteria, protozoa and helminth. Helminth eggs are very resistant to thermal inactivation. The Ascaris lumbricoids

8. Electrochemical control of aqueous solution pesticide: study for the degradation of 2,4-dichlorophenoxyacetic acid / Controle eletroquimico de herbicida em soluções aquosas : estudo da degradação do acido 2,4-diclorofenoxiacetico
In this work, the performance of the H2O2 electrogeneration process from O2 reduction on a reticulated vitreous carbon cathode was investigated. The process was also use for the oxidation of the herbicide 2,4-dichlorophenoxyacetic acid. Firstly, cyclic voltammetries were used for the identification of possible reduction reactions of the herbicide. The suppor

12. MODELAGEM DE COMPENSADORES ESTÁTICOS TIPO REATOR SATURADO E SUA IMPLEMENTAÇÃO NUM PROGRAMA DE ESTABILIDADE TRANSITÓRIA / SATURATED REACTOR TYPE STATIC COMPENSATOR MODELLING AND ITS IMPLEMENTATION IN A DIGITAL TRANSIENT STABILITY PROGRAM
The model comprises fixed capacitor banks, for the generation of reactive power, in parallel with the saturated reactor, for the absortion of reactive power. The model equations are obtained in first place and from them the block diagram is developed for implementation in the program. Tests are carried out (digital simulations) using power systems under dist
