Brazil is undoubtedly a country that has many viable natural resources that it can make the most of. The guaran in this particular case, is a fruit that only grows in this region of the Amazon and which gives this country the opportunity to position itself competitively in the soft drink industry. It is no wonder that the exploitation of this fruit is not exclusively in the hands of the Manues Indian anymore and has become a product that has helped generate national wealth.

In this letter, we evaluate the conversion efficiency of thermally isolated Seebeck nanoantennas by numerical simulations and discuss their uses and scope for energy harvesting applications. This analysis includes the simple case of titanium-nickel dipoles suspended in air above the substrate by a 200 nm silicon dioxide membrane to isolate the heat dissipation. Results show that substantially thermal gradients are induced along the devices leading to a harvesting efficiency around 10-4 %, 400 % higher than the previously reported Seebeck nanoantennas. In the light of these results, different optimizing strategies should be considered in order to make the Seebeck nanoantennas useful for harvesting applications.

Una revista de psicoanálisis en la universidad, con las condiciones que la época de la academia ha impuesto sobre las investigaciones, de modelos de res- tricción formal y de control burocrático concomitante, nace con todas las posi- bilidades de caer en un nido de trampas. Sabemos de la selva de confusiones que precede y envuelve al psicoanálisis en la universidad; desde el doble movimiento freudiano que requería la entrada del psicoanálisis y la defensa simultánea al psicoanálisis lego. No deja de mantener ese tono paradojal el hecho de que actualmente siga operando una fuerza centrífuga, que temerosamente procura impedir que la universidad fagocite al psicoanálisis. ¿Cómo cuidar al psicoaná- lisis de la aceptación e incorporación universitaria?
