Aproximación al pintor Epifanio Díaz de Arcaute (1845-1910)

[ES]Con este trabajo pretendemos aproximarnos a la figura de Epifanio Díaz de Arcaute (1845-1910), un pintor no demasiado conocido y con una producción artística, por el momento, escasa. Su formación fue tradicional y académica, vinculada a la Academia de Bellas Artes de Vitoria, de la que terminó siendo profesor.

Reise im innern von brasilien : auf allerhochsten befehl selner majestat des kaisers von osterreich, Franz des Esten, in den jahren 1817-1821 unternonmen und herausgegeben

O primeiro volume foi editado em 1832 e o segundo em 1837, após a morte do autor, fato que contribuiu para a pouco acurada nomenclatura em português verificada no segundo volume, conforme afirma Borba de Moraes. A grande importância do trabalho de Pohl residiu na descrição de Goiás, à época, uma parte do Brasil quase desconhecida para os cientistas estrangeiros. Seu texto contém descrições sobre a arquitetura colonial e do século XIX. Pohl também produziu um atlas que complementou, por meio de belas ilustrações, o trabalho contido nesses dois volumes. Estes, especialmente se acompanhados do atlas, são um trabalho mais raro do que os relativos às viagens de Martins

Computation of turbulence-generated noise by large-eddy simulation

The hybrid method of large eddy simulation (LES) and the Lighthill analogy is being developed to compute the sound radiated from turbulent flows. The results obtained from the hybrid method are often contaminated by the absence of small scales in LES, since the energy level of sound is much smaller than that of turbulent flows. Previous researches investigate the effects of subgrid sacle (SGS) eddies on the frequency spectra of sound radiated by isotropic turbulence and suggest a SGS noise model to represent the SGS contributions to the frequency spectra. Their investigations are conducted in physical space and are unavoidably influenced by boundary conditions. In this paper, we propose to perform such calculations in Fourier space so that the effects of boundary conditions can be correctly treated. Posteriori tests are carried out to investigate the SGS contribution to the sound. The results obtained recover the -7/2 law within certain wave-number ranges, but under-estimate the amplitudes of the frequency spectra. The reason for the underestimation is also discussed.

Prediction of particle distribution in isotropic turbulence by large-eddy simulation

The recent application of large-eddy simulation (LES) to particle-laden turbulence requires that the LES with a subgrid scale (SGS) model could accurately predict particle distributions. Usually, a SGS particle model is used to recover the small-scale structures of velocity fields. In this study, we propose a rescaling technique to recover the effects of small-scale motions on the preferential concentration of inertial particles. The technique is used to simulate particle distribution in isotropic turbulence by LES and produce consistent results with direct numerical simulation (DNS). Key words: particle distribution, particle-laden turbulence, large-eddy simulation, subgrid scale model.

SAIL Panama Canal Zone Project 2008 : Biological Survey of Panama (1910-1912)

During the 18th Annual 2008 SAIL meeting at the Smithsonian Tropical Research Institute in Panama, a suggestion was made for the need to digitize and make available through the Aquatic Commons some of the early documents related to the U.S. biological survey of Panama from 1910 to 1912. With SAIL’s endeavor, a new digital project was born and this presentation describes its process, beginning to final product. The main source consulted for determining copyright clear publications was: Heckadon-Moreno. 2004. Naturalists on the Isthmus of Panama: A hundred years of natural history on the biological bridge of the Americas. 1st English ed.
