of different properties resulting from a high surface free energy (Glass) and a low surface free energy (PTFE) solids, and how polar and dispersive components of sur- face free

Theses results suggest that the ED method, based on active physics learning paradigm, is a good model for a significant improvement of students’ attitudes toward physics as a

Enquanto pensava na melhor maneira de apresent´a-lo e tornar o conceito mais claro, surgiu a ideia da rela¸c˜ao com a afina¸c˜ao do piano ao observar um profissional afinando o piano

Once the variables have been identified, and the base to write the dimensions of these variables has been selected, the next step is to choose the so-called ‘new base’ of

El modelo de estudio “nativo” de los estudiantes es consecuencia de los a˜ nos de estudios previos, y se debe de modificar por un modelo que permita alcanzar las competencias

To test this idea we individually recorded all keys of an aurally tuned piano, computed their power spectra and reorganized them in logarithmic bins in order to account for the

If linearly polarized light impinges the birefringent layer, then one of the components (the ordinary wave or the extraordinary wave) will be retarded: for this reason

This equation con- tains a force density, which we call Maxwell’s force density, which generalizes the Lorentz force density, now including total fields rather than only
