14. The use of molecular spectra simulation for diagnostics of reactive flows
Abstract: The C2* radical is used as a system probe tool to the reactive flow diagnostic, and it was chosen due to its large occurrence in plasma and combustion in aeronautics and aerospace applications. The rotational temperatures of C2* species were determined by the comparison between experimental and theoretical data. The simulation code was developed by

15. Photodynamic antimicrobial chemotherapy (PACT) for the treatment of malaria, leishmaniasis and trypanosomiasis
A photodynamic effect occurs when photosensitiser molecules absorb light and dissipate the absorbed energy by transferring it to biological acceptors (usually oxygen), generating an excess of reactive species that are able to force cells into death pathways. Several tropical diseases present physiopathological aspects that are accessible to the application o

16. Efeitos de três diferentes tipos de treinamento de força das adaptações neuromuculares e morfológicas no desempenho de capacidades funcionais em mulheres idosas
Os diferentes tipos de treinamento de força (TF) apresentam distintas adaptações do tecido muscular como o desenvolvimento de força máxima, potência e/ou força reativa muscular. Dentre estes tipos de TF, estão os treinamentos de força Tradicional, Treinamento de Potência e de Treinamento de Força Reativa, em que está presente o ciclo-alongamento-

17. Ressonadores de microdiscos com região ativa nanoestruturada bombeados por injeção eletrônica / Microdisk resonators with nanostructured active region pumped by electronic injection
This doctorate¿s thesis presents the growth of InAs quantum dots directly on high bandgap InGaAsP (?g=1420 nm) barriers to be used as the active region of microdisk resonators with emission in the C-band (1520¿1570 nm). Based on photoluminescence and atomic force microscopy experiments, the occurrence of inter-diffusion on the InAs/InGaAsP interface is cal

18. Avaliação do tratamento de lixiviado de aterro sanitário através de processo oxidativo avançado conjugado com sistema de separação por membranas
The landfill leachate is characterized by high recalcitrant organic matter concentration, ammonia and toxic compounds. This effluent can be an environmental problem due to its high pollutant potential when it is released without treatment. Studies reported in the literature showed that biological processes are not sufficient in meeting the discharge standard

19. Serviços ancilares através da geração distribuíba : reserva de potência ativa e suporte de reativos / Ancillary services provide by distributed generation : active power reserves and reactive support
In order to set the principles for a future regulatory framework in Brazil which involves the participation of distributed generation (DG) to provide ancillary services; this work presents an analysis developed in three broad areas, technical, economic and regulatory. A specific objective of the project is to make an analysis of the use of the DG for the sup

20. Analysis of the dentin-pulp complex in teeth submitted to orthodontic movement in rats
In order to microscopically analyze the pulpal effects of orthodontic movement, 49 maxillary first molars of rats were submitted to orthodontic appliance composed of a closed coil spring anchored to the maxillary incisors, placed for the achievement of mesial movement. MATERIAL AND METHODS: Ten animals were used as the control group and were not submitted to

21. Interferência de harmônicas em equipamentos de medição de energia elétrica. / Harmonic interference in equipment for measurement of eletrical energy.
This work addresses the reliability of energy meters in nonsinusoidal systems, looking for the increase of quality in the electric energy billing. To that purpose, it focuses on a fairer metering and a better relationship between the concessionaire and consumer. The tests were carried through in the laboratories of Eletropaulo, of the Electro-Technology and

22. Glass Difractive Optical Elements (DOEs) with complex modulation DLC thin film coated
We developed a complex (amplitude and phase) modulation Diffractive Optical Element (DOE) with four phase levels, which is based in a glass substrate coated with DLC (Diamond Like Carbon) thin film as the amplitude modulator. The DLC film was deposited by magnetron reactive sputtering with a graphite target and methane gas in an optical glass surface. The gl

23. Ascorbic acid and citric flavonoids for broilers under heat stress: effects on performance and meat quality
The aim of this study was to evaluate the effects of increasing doses of ascorbic acid (AA) and citric flavonoids (quercetin and rutin) on the performance and meat quality characteristics of broilers submitted to cyclic heat stress. Four-hundred one-day-old female Ross 308 were housed in 40 battery cages a in temperature controlled room. Treatments consisted

24. A study of TiAlN coatings prepared by rf co-sputtering
Using the reactive magnetron rf co-sputtering technique and a Ti target partially covered with a small Al plate, TiAlN coatings were made on c-Si in a reactive atmosphere of nitrogen and argon. Coatings were deposited on substrates at 22°C and at 150°C. The substrate temperature notably affected the thickness, crystalline grain size, and hardness of the co
