25. Variação da qualidade da água do escoamento superficial de duas bacias de drenagem de Natal/RN - Brasil
The urban drainage is one of the powers of environmental sanitation and its scope is the quantitative and qualitative aspects. In decision making of managers and the engineering aspects of design are almost always taken into account only the quantitative aspects. However, the waters of the runoff have the highest concentrations of pollutants at the beginning

26. Magnesium and its alloys as degradable biomaterials: corrosion studies using potentiodynamic and EIS electrochemical techniques
Magnesium is potentially useful for orthopaedic and cardiovascular applications. However, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. In industrial media the behaviour of several magnesium alloys have been probed to be better than magnesium performance. However, the information related to the

28. Estudo do efeito de fluxos na soldagem ATIG de alumínio
The feasibility of using ATIG (active flux TIG) welding for surface oxide removal in aluminum welding with direct polarity was evaluated. The influence of the flux on different conditions of specimen surface, variations in welding parameters and the effect of metal base composition was also evaluated. Welding trials were performed in a mechanized jig using a

30. Uso de biofertilizantes de rochas com enxofre e Inoculado com acidithiobacillus em Argissolo Acinzentado do Vale do São Francisco cultivado com melão.
The production of biofertilizers from rocks is a practical process that may reduce the energy consumption and promote nutrients availability for plant growth. Nutrient content of P and K biofertilizers varied according to the methodology and the used material. Presently biofertilizers are known as fertilizers that are produced using different organic by-prod

31. Optimization of random amplified polymorphic DNA techniques for use in genetic studies of Cuban triatominae
Random amplified polymorphic DNA (RAPD) technique is a simple and reliable method to detect DNA polymorphism. Several factors can affect the amplification profiles, thereby causing false bands and non-reproducibility of assay. In this study, we analyzed the effect of changing the concentration of primer, magnesium chloride, template DNA and Taq DNA polymeras
