Análise da vibração para o controle do funcionamento de um ventilador de um sistema de exaustão

This work has as objective to show the vibrational analysis as a method of predictive maintenance as an auxiliar procedure in the fail detection in equipments, most specifically in the rotative ones, and with that help the maintenance team to have conditions to foresee the right time to do the swap of the components of the systems, what would lead to failures. Knowing the exact moment the resources of people and money can be focused in the critic operations to the plant. This technic has been already studied for more then 30 years and was widely used in this work, not only as an equipment condition verification method, but also, after the equipment replacement, was used to prove that the new fan was operating under the best work conditions and with that maintenance could return to contol the vibration level of the equipment, not being necessary any kind of intervention

Cidades sustentáveis: análise comparativa com cidades contemporâneas

Currently the world is under an energy revolution, every day more technologies are developed in order to better use the energy for having better energy efficiency of equipment and processes with minimal environmental degradation. Taking into account that thousands of people live in built environments in the context of cities and that the energy flow to this location is significant, it is important to study the built environment as a potential source of savings, energy recovery and regeneration, because cities are the major bottlenecks energetic. Therefore, this study aimed to examine and to list the most important and promising technologies to be used in the built environment to collect or save energy that would be wasted, such as clothes that generate energy through movement or solar incidence, facades of buildings that generate energy due to solar radiation, fitness centers that produce electricity due to the rotation used in fitness equipment for athletes, elevators that take advantage of the potential energy or use it more rationally, generators that take advantage of energy vibrational, and finally more sustainable vehicles with higher performance and less degrading the environment. The information and results obtained from this study show that the technologies used to harness energy before lost are increasingly evident and also is increased the progress relative to the energy use in a urban context. In the closure, a comparison of energy expenditure between a city that uses some of these sustainable technologies and another of the same size with conventional habits is presented

Síntese e caracterização do complexo de lantânio (III) e indometacina no estado sólido

In this study, the drug indomethacin, a non-steroidal anti-inflammatory indoleacetic acid derivative and the complex of indomethacin and lanthanum (III) in solid form were synthesized and characterized by Thermogravimetry (TGA), Differential Thermal Analysis (DTA), Differential Scanning Calorimetry (DSC) and powder X-ray diffractometry (XRD), infrared vibrational spectroscopy by diffuse reflectance (FTIR) and complexometric titration with EDTA. With the TG curves it was possible to determine the stoichiometry of the complex as La(Ind)3·3.5H2O where Ind is the drug indomethacin. The result of thermal analyzes provided information on the thermal stability, enthalpy of dehydration and thermal behavior of the compounds. The infrared spectrum and with the aid of theoretical calculations suggests that the indomethacin is coordinated by the carboxylate group in the bidentate mode

The oxidation of hydroxylamine on Pt-, and Pd-modified Au electrodes in aqueous electrolytes: Electrochemical and in situ spectroscopic studies

The electrooxidation of hydroxylamine, NH2OH, in 0.1 M phosphate buffer (PB, pH = 7) on Pt-, and Pd-modified Au electrodes prepared by galvanic displacement of underpotential deposited Cu, was investigated by electrochemical techniques and three and in situ vibrational probes, substrate-induced surface enhanced Raman scattering, SI-SERS, surface enhanced infrared absorption, SEIRAS, and Fourier transform infrared reflection-absorption, IRAS, spectroscopies. Analyses of the results obtained made it possible to identify at low overpotentials, solution phase (sol) and adsorbed (ads) nitric oxide, NO, as well as solution phase nitrous oxide, N2O. As the potential was increased, the peak(s) ascribed to NO(ads) gained in intensity and new features associated with NO2−(ads) and NO2−(sol) were clearly discerned. Further excursion toward higher potentials yielded an additional peak assigned to NO2(ads). This behavior is analogous to that found for bare Au electrodes in a potential region in which the metal is at least partially oxidized under otherwise the same experimental conditions.
