Acanthocefalan eggs in animal coprolites from archaeological sites from Brazil Ovos de acantocéfalo em coprólitos de animais em sítios arqueológicos do Brasil

open access: yesMemorias do Instituto Oswaldo Cruz, 1989
An important point in paleoparasitology is the correct diagnosis of the origin of coprolites found in archaelogical sites. The identification of human and animal coprolites, through the study of the shape, size, charactheristics after rehydration ...

Continuum description of profile scaling in nanostructure decay

open access: yes, 2003
The relaxation of axisymmetric crystal surfaces with a single facet below the roughening transition is studied via a continuum approach that accounts for step energy g_1 and step-step interaction energy g_3>0.

Universal Scaling in Mixing Correlated Growth with Randomness

open access: yes, 2005
We study two-component growth that mixes random deposition (RD) with a correlated growth process that occurs with probability p. We find that these composite systems are in the universality class of the correlated growth process.

More Accurate Theory for Bose-Einstein Condensation Fraction

open access: yes, 2007
In the thermodynamic limit the ratio of system size to thermal de Broglie wavelength tends to infinity and the volume per particle of the system is constant. Our familiar Bose-Einstein statistics is absolutely valid in the thermodynamic limit. For finite

Novel continuum modeling of crystal surface evolution

open access: yes, 2002
We propose a novel approach to continuum modeling of the dynamics of crystal surfaces. Our model follows the evolution of an ensemble of step configurations, which are consistent with the macroscopic surface profile.

A MORAL SOCIAL DA DIVISA

open access: yesReflexão
Foi a filosofia francesa que estabeleceu, no século XVIII, a doutrina dos Direitos do Homem e a implantou na teoria política, e no conceito de vida política. Quando se aprecia a obra filosófica do século XVIII, esta se revela heterogênea, antinômica e é

Distributed Unmixing of Hyperspectral Data With Sparsity Constraint

open access: yes, 2017
Spectral unmixing (SU) is a data processing problem in hyperspectral remote sensing. The significant challenge in the SU problem is how to identify endmembers and their weights, accurately. For estimation of signature and fractional abundance matrices in
