Por uma história do desenvolvimento

This paper proposes a discussion on the need to prepare a history of development through effective approaches and methods of its own history. The objective is to show how, until now, historians have not produced a history of development in light of the discussions and disputes related to the structuring of history as a field of knowledge. To this end, it was demonstrated how history can help to identify the borders of history that allowed the consecration of a limited development model and tied only to criteria of economic performance.

Developing descriptors to predict mechanical properties of nanotubes

Descriptors and quantitative structure property relationships (QSPR) were investigated for mechanical property prediction of carbon nanotubes (CNTs). 78 molecular dynamics (MD) simulations were carried out, and 20 descriptors were calculated to build quantitative structure property relationships (QSPRs) for Young's modulus and Poisson's ratio in two separate analyses: vacancy only and vacancy plus methyl functionalization. In the first analysis, C N2/CT (number of non-sp2 hybridized carbons per the total carbons) and chiral angle were identified as critical descriptors for both Young's modulus and Poisson's ratio. Further analysis and literature findings indicate the effect of chiral angle is negligible at larger CNT radii for both properties. Raman spectroscopy can be used to measure CN2/C T, providing a direct link between experimental and computational results. Poisson's ratio approaches two different limiting values as CNT radii increases: 0.23-0.25 for chiral and armchair CNTs and 0.10 for zigzag CNTs (surface defects <3%). In the second analysis, the critical descriptors were CN2/CT, chiral angle, and MN/CT (number of methyl groups per total carbons). These results imply new types of defects can be represented as a new descriptor in QSPR models. Finally, results are qualified and quantified against experimental data. © 2013 American Chemical Society.

Dynamical properties for a mixed Fermi accelerator model

The behavior of the decay of velocity in a semi-dissipative one-dimensional Fermi accelerator model is considered. Two different kinds of dissipative forces were considered: (i) F-v and; (ii) F-v2. We prove the decay of velocity is linear for (i) and exponential for (ii). During the decay, the particles move along specific corridors which are constructed by the borders of the stable manifolds of saddle points. These corridors organize themselves in a very complicated way in the phase space leading the basin of attraction of the sinks to be seemingly of fractal type. © 2013 Elsevier B.V.

Indeterminaçáo e fenomenôs fronteiriços: Consideraçóes se gundo o ponto de vista do pragmatismo peirceano

Pragmatism, as a formal method, has provided a fabulous arena for discussions about the way concepts may be constructed, irrespective of any anthropomorphic or linguistic position. We will see that the pragmatic maxim possesses an interesting thesis regarding the indetermination of the meaning. Such idea helps to understand the transit between the indefinite and the defined, indeterminate and determined, as well as some found intermediate borders in the processes of relative determination.
