1. DIGITAL SIMULATION SYSTEM OF NEUTRON PARAMETERS OF THE TRIGA IPR-R1 NUCLEAR RESEARCH REACTOR / SISTEMA DIGITAL PARA SIMULAÇÃO DOS PARÂMETROS NEUTRÔNICOS DO REATOR NUCLEAR DE PESQUISA TRIGA IPR-1
The IPR-R1 TRIGA Mark I nuclear research reactor, at the Nuclear Technology Development Center (CDTN), is a pool type reactor cooling by light water. TRIGA reactors (Training, Research, Isotope, General Atomics) were designed for research, training and radioisotope production. The International Atomic Energy Agency (IAEA) recommends the use of safety and fri

2. Lamella sedimentation: alternative for treatment of overflow sewage - study in ETE Martim de Sá (Caraguatatuba/SP). / Decantação acelerada: alternativa para o tratamento de vazão excedente de esgoto - estudo na ETE Martim de Sá (Caraguatatuba/SP).
This study was motivated by the need to treat high wastewater influent exceeding in sewage treatment plants, which occurs on days of heavy rain. The central hypothesis of this study is that the physical-chemical process to treat dilute sewage overflow, it can be advantageous with respect to increased capacity and expansion of biological systems. The research

3. Avaliação da utilização de colifagos como indicadores virais a partir da análise de enterovírus e adenovírus em efluentes tratados por diferentes processos biológicos
Domestic sewage contains a high amount of bacteria and other pathogens and non pathogens that are discharged into water bodies. Contamination of water by the presence of pathogenic bacteria and viruses, brings undesirable consequences, especially for public health. The objective of this work was to evaluate the possibility of using analysis of coliphages as

4. Monitoração e diagnóstico para detecção de falhas de sensores utilizando a metodologia GMDH / Monitoring and diagnosis for sensor fault detection using GMDH methodology
O sistema de detecção de falhas e diagnóstico é um sistema de suporte ao operador dedicado a funções específicas que alertam os operadores para problemas de falhas em sensores e atuadores, e auxiliam no diagnóstico antes que os limites normais de alarmes sejam atingidos. Sistemas de suporte ao operador surgiram para diminuir a complexidade dos painé

5. DEVELOPMENT OF AN ARTIFICIAL NEURAL NETWORK FOR MONITORING AND DIAGNOSIS OF SENSOR FAULT AND DETECTION IN THE IEA-R1 RESEARCH REACTOR AT IPEN / "Utilização de redes neurais artificiais na monitoração e detecção de falhas em sensores do Reator IEA-R1"
The increasing demand on quality in production processes has encouraged the development of several studies on Monitoring and Diagnosis Systems in industrial plant, where the interruption of the production due to some unexpected change can bring risk to the operators security besides provoking economic losses, increasing the costs to repair some damaged equ

6. "Sistemas de análises químicas em fluxo explorando multi-impulsão e detecção espectrofotométrica: aplicação a formulações farmacêuticas e a extratos de solos" / Multi-pumping flow systems with spectrophotometric detection: application to analysis of pharmaceuticals and soil extracts
Multi-pumping flow systems (MP) utilize solenoid pumps as fluid propelling devices, which deliver pulsed flows. This feature was evaluated in relation to the design, operation and performance of the system, to the mixing conditions, and to the dispersion of the introduced solution. The general evaluation of the MP systems involved investigations about precis

7. An overview of electrical tomographic measurements in pharmaceutical and related application areas
Tomographic measurement techniques offer the opportunity to quantify the degree of homogeneity of particulate suspensions and other multiphase mixtures. Electrical resistance tomography is a relatively simple and inexpensive technique for measuring the distribution of electrical conductivity within multiphase systems. This can provide pertinent information a

8. Monitoring Gene Expression in Mixed Microbial Communities by Using DNA Microarrays
A DNA microarray to monitor the expression of bacterial metabolic genes within mixed microbial communities was designed and tested. Total RNA was extracted from pure and mixed cultures containing the 2,4-dichlorophenoxyacetic acid (2,4-D)-degrading bacterium Ralstonia eutropha JMP134, and the inducing agent 2,4-D. Induction of the 2,4-D catabolic genes prese
