Total internal reflection microscopy (TIRM) measures the position of a Brownian particle above an interface by using its scattering of an evanescent wave. From the knowledge of the trajectory it is possible to reconstruct the interaction potential between the Brownian…

"En los sistemas de distribución de energía el eléctrica típicos es común encontrar cargas de tipo monofásico. Sin embargo estos sistemas son generalmente desbalanceados, debido a que la cargas son desigualmente distribuidas entre las fases, y distorsionados por la gran…

Interstellar dust was first identified through the extinction that it causes of optical starlight. Initially, observational and theoretical studies of extinction were made to identify simple ways of removing the effect of extinction. Over the last few decades it has…

In this study, we focus on the polarization angle of light scattered by terrestrial atmosphere-surface systems. The polarization angle describes the orientation of the plane in which the linearly polarized portion of light propagates. We show for skylight how this…

Torres-Saillant’s book contends, as its author explains, that as a region the Caribbean is a differentiated “civilizational” zone produced by the encounter of multiple cultures and by contending political and economic interests. This region, according to him, has produced an…

When Alexander Dent arrived in Brazil in 1998, he was unaware of the existence of the rural genres that are the focus of this book. He had listened to bossa nova, MPB, Tropicália, death metal, forró, and techno, among other…

One does not have to be a fierce advocate of dialectics to consider the claim that the exercise of dystopic imagination may represent a necessary stage to think a better world. If it is good to know the worst, that does not…
