1. Modelagem e otimização de um robô de arquitetura paralela para aplicações industriais. / Modeling and optimization of a parallel architecture robot for industrial applications.
This work is about the study of parallel architecture robots, focusing in modeling and optimization. No physical prototypes were built, although the virtual models can help those willing to do so. After searching for an application that could benefit from the use of a parallel robot, another search was made, this time for the right architecture type. After s

2. Scanning force microscopy reveals ellipsoid shape of chicken erythrocyte nucleosomes.
Scanning force microscopy was used to investigate the conformation of hypotonic spread chicken erythrocyte nucleosomes. Nucleosomal chains were prepared in low-salt conditions and fixed before centrifugation onto glass coverslips and air drying. The images of single nucleosomes were isolated by image processing, and the height and geometry of the resulting t

3. Nanodissection and high-resolution imaging of the Rhodopseudomonas viridis photosynthetic core complex in native membranes by AFM
In photosynthesis, highly organized multiprotein assemblies convert sunlight into biochemical energy with high efficiency. A challenge in structural biology is to analyze such supramolecular complexes in native membranes. Atomic force microscopy (AFM) with high lateral resolution, high signal-to-noise ratio, and the possibility to nanodissect biological samp

4. Electrohydrodynamic Model of Vesicle Deformation in Alternating Electric Fields
We develop an analytical theory to explain the experimentally observed morphological transitions of quasispherical giant vesicles induced by alternating electric fields. The model treats the inner and suspending media as lossy dielectrics, and the membrane as an impermeable flexible incompressible–fluid sheet. The vesicle shape is obtained by balancing ele
