1. Disciplina de Pneumologia, Instituto do Coração, Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo, São Paulo (SP) Brasil. 2. Editor-Chefe do JBP Jornal Brasileiro de Pneumologia, Brasília (DF) Brasil. The Portuguese word momento can be translated in a number of ways. It is first and foremost translated as “moment”, which has an eminently temporal connotation, indicating a definite or indeterminate period of time, a secondary meaning (in Portuguese only) being that of a specific circumstance. However, it can also be translated as “momentum”, as the term is used in the field of physics, indicating the force imposed on a rotational system, generating an impulse or change.

متن کاملMomentum Transfer Rate Constants for Collision of Cl-with Trans-Dichloroethylene and Para-Difluorobenzene
A classical theory is developed which calculates the momentum transfer rate constant between an ion and a non-polar molecule. The model takes into consideration the effect of diffraction outside the capture limit on the rate constants. The theory is used to calculate momentum transfer rate constant for Cl- with trans-dichloroethylene and para-difluorobenzene. Theoretical results ...

The shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. In reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a S-shape profile. Th...
