The 12 prophets dataset

The "Ajeijadinho 3D" project is an initiative supported by the University of S\~ao Paulo (Museum of Science and Dean of Culture and Extension), which involves the 3D digitization of art works of Brazilian sculptor Antonio Francisco Lisboa, better known as Aleijadinho. The project made use of advanced acquisition and processing of 3D meshes for preservation and dissemination of the cultural heritage. The dissemination occurs through a Web portal, so that the population has the opportunity to meet the art works in detail using 3D visualization and interaction. The portal address is http://www.aleijadinho3d.icmc.usp.br. The 3D acquisitions were conducted over a week at the end of July 2013 in the cities of Ouro Preto, MG, Brazil and Congonhas do Campo, MG, Brazil. The scanning was done with a special equipment supplied by company Leica Geosystems, which allowed the work to take place at distances between 10 and 30 meters, defining a non-invasive procedure, simplified logistics, and without the need for preparation or isolation of the sites. In Ouro Preto, we digitized the churches of Francisco of Assis, Our Lady of Carmo, and Our Lady of Mercy; in Congonhas do Campo we scanned the entire Sanctuary of Bom Jesus de Matosinhos and his 12 prophets. Once scanned, the art works went through a long process of preparation, which required careful handling of meshes done by experts from the University of S\~ao Paulo in partnership with company Imprimate.Comment: Full dataset online at http://aleijadinho3d.icmc.usp.br/data.htm

Self-Interacting Electromagnetic Fields and a Classical Discussion on the Stability of the Electric Charge

The present work proposes a discussion on the self-energy of charged particles in the framework of nonlinear electrodynamics. We seek magnet- ically stable solutions generated by purely electric charges whose electric and magnetic fields are computed as solutions to the Born-Infeld equa- tions. The approach yields rich internal structures that can be described in terms of the physical fields with explicit analytic solutions. This suggests that the anomalous field probably originates from a magnetic excitation in the vacuum due to the presence of the very intense electric field. In addition, the magnetic contribution has been found to exert a negative pressure on the charge. This, in turn, balances the electric repulsion, in such a way that the self-interaction of the field appears as a simple and natural classical mechanism that is able to account for the stability of the electron charge.Comment: 8 pages, 1 figur

Aspectos fenológicos de Hibiscus sabdariff L. (Malvaceae).

A espécie Hibiscus sabdariffa L., pertencente à família Malvaceae, popularmente conhecida como vinagreira possui inúmeras propriedades terapêuticas já comprovadas cientificamente como antioxidante, antiescorbútico, diurético, anti-hipertensivo, antirreumático e antimicrobiano. O trabalho teve como objetivo caracterizar aspectos da fenologia de H. sabdariffa cultivada no horto de plantas medicinais da Embrapa Amazônia Oriental durante o período de 2010 a 2011. Foram observados diariamente cinco indivíduos organizados para demonstração mensal a partir de registro de presença ou ausência da fenofase. Os dados registrados mostraram que no ano de 2010 ocorreu floração em seis meses, sendo em fevereiro registrada a maior frequência com 14 dias. Já no ano de 2011 a floração ocorreu somente em três meses a maior frequência foi observada em setembro com 21 dias e a menor no mês de outubro com 18 dias. Não houve ocorrência de frutificação para os dois anos
