13. Tratamento de água para consumo humano de reservatório eutrofizado através de pré e interoxidação, adsorção em carvão ativado e dupla filtração / Drinking water treatment of eutrophic reservoir by pre and interoxidation, activated carbon adsorption and double filtration
Disordered basins occupation provoked acceleration of eutrophication, which besides purely aesthetic and landscaping problems, results in occurrence of high phytoplankton densities with potentially toxic cyanobacteria dominance. Alongside physical aging and consequent deterioration of installations, usual treatment technologies do not provide adequate condit

14. Estudo experimental e numérico do sistema de admissão de um motor de combustão interna / Experimental and numerical study of the intake system of an internal combustion engine
During the process of intake air in the internal combustion engine it has been noted that air flow is not ideal, i.e., the cylinder volume is not completely occupied concerning the variation of specific mass and the charge loss along the feed system. Consequently, the volumetric efficiency in the cylinder reaches low values of performance, affecting the engi

15. Contribution to the study of a non-invasive probe for measuring the water thickness in a core-annular flow / Contribuição ao estudo de um medidor não-invasivo da espessura da camada de agua em um escoamento anular oleo-agua
This work is a contribution to the study of a non-intrusive probe for measurement of the thickness of the water layer of a core-annular flow. A capacitive probe was built and its static performance was evaluated from tests executed in a specially designed bench-scale apparatus. In addition, evaluation of the dynamic performance was made possible from fluid-f

16. Tratamento de efluentes da carcinicultura por flotação em coluna e flotação
The high productivity in the breeding of shrimp makes it necessary to approach some aspects to their sustainability, particularly the aquatic environment of the nursery. Thus, the treatment of effluents originating from the shrimp becomes of fundamental importance, considering the need to minimize the environmental impacts generated by this productive activi

17. 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

19. Produção de cefamicina C por Streptomyces clavuligerus em batelada e batelada alimentada
Cephamycin C (CephC) is a natural antibiotic produced by Streptomyces clavuligerus that presents β-lactamases resistance, enzymes that clives β-lactam of antibiotics. The aim of present work was study cephamycin production by Streptomyces clavuligerus in batch and fed-batch cultivations, in order to define important parameters as culture medium and

20. Clogging dynamics of driplines under the application of soluble iron, suspended solids and fitoplankton / Dinâmica do entumpimento de tubos gotejadores sob aplicação de ferro solúvel, sólidos em suspensão e fitoplâncton
This research project was developed to quantify possible disturbances of flow rate in drip emitters subject to the application of soluble iron, suspended solids (soil particles) in water containing organic material (phytoplankton / algae), with emitters outlet positioned down and up. Two experiments were carried out A and B during 12 months period, using 16

21. Estudo de desempenho do aquecedor solar de baixo custo
One alternative to reduce consumption of electric energy to heat water will be popularize the use of solar energy. This work comes to contribute of studies about the Low Cost Solar Heater , ASBC, which is a new concept of solar water heater for home, all made by polymeric materials with relatively small investment and can be built manually. The plate of the

22. Estudo experimental da influência de um ressonador de volume variável na massa de ar admitida por um motor de combustão interna
The dynamic of intake manifold admission on internal combustion engines involves parameters such as length, diameter, camshaft rotation and other geometries and accessories. The alternative movements of the admission valves and piston produce the phenomena of generation of pressure waves that spread through the conduit. Such waves, if well used, can increase

23. Modelo matemático para avaliação hidrodinâmica em reatores tubulares operando em regime não-permanente / Mathematical model for hydrodynamic evaluation of pipe reactors with diffusion operated in non-steady flow
Mathematical models for hydrodynamic characteristics evaluation of reactors are commonly used however there is a lack of information in the literature concerning the application of mathematical modeling for non-steady state flow. In this thesis, it is presented a non-steady mathematical model to simulate the hydrodynamic behavior of pipe flow reactors with d

24. Desempenho de sistema de irrigação por gotejamento utilizado na aplicação de água residuária de suinocultura / Performance of dripping irrigation system using swine wastewater
The objective of this work was to analyze the performance of a drip irrigation system using swine wastewater. The following parameters were evaluated: (a) removal of suspended solids, oils and greases by passing the effluent through sloped static screens; (b) influence of service pressure on clogging of drippers operating with effluent and water; and (c) eff
