Parasites of wild primates are important for conservation biology and human health due to their high potential to infect humans. In the Amazon region, non-human primates are commonly infected by Trypanosoma cruzi and T. rangeli, which are also infective to man and several mammals. This is the first survey of trypanosomiasis in a critically endangered species of tamarin, Saguinus bicolor (Callitrichidae),...
A method to minimize the components of uncertainty of a measurement of the quantities of electric power and energy is presented in this work. The measurement procedure is adopted to disseminate the referred units with smaller uncertainties than those inherited due to traceability of secondary standards
The paper gives an account on a new power measuring system, based on digital sampling, which was developed by the National Institute of Metrology (INMETRO) of Brazil. The goal of the project was to achieve the highest possible accuracy at the presence of considerable harmonic distortions, to guarantee full traceability to national standards and to minimize the costs of obtaining a high quality reference...
