Estudo da estrutura de nanoilhas de grafeno por microscopia de varredura por tunelamento
(Universidade Federal de Minas GeraisUFMG, 2017-06-14)
The epitaxial growth of graphene over metallic surfaces is one of the promising methods for the developing of technological applications. Due to the small mismatch between the two lattices and the strong interaction, the ...
Axial regeneration in segmented animals: A post-embryonic reboot of the segmentation process
(CRC Press - Taylor & Francis Group, 2020)
Axial regeneration, the ability to regrow structures along the main body axis, is a widespread, likely ancestral trait of metazoans. Despite its assumed adaptive value, regenerative ability has decreased, disappeared and ...

Control and optimization strategies to maximize the energy generated by photovoltaic sources
(2017)
This thesis presents control and optimization techniques to improve the energy generated by Photovoltaic (PV) power systems. The first part of this work presents an analysis of the Perturb and Observe MPPT algorithm, ...
Population genetic structure and historical dispersal patterns in the subterranean rodent Ctenomys “chasiquensis” from the southeastern Pampas region, Argentina
(Elsevier Gmbh, 2016-05)
Gene flow plays an essential role in the evolutionary history of the organisms and helps to identify those historical landscape features that most likely had affected the dispersal patterns. In this work, we assess, using ...
