Autor: Nilson T. Mascia, David E. Kretschmann, Aléxia B. Ribeiro

Publikováno v: Materials Research, Vol 23, Iss 3 (2020)

Abstract The discussion of the importance of the perpendicular tension strength to better understand the wood’s mechanical behavior in several situations, such as shrinkage analysis, glued laminated beam failure analysis, has become clear that more

ON THE EFFECT OF THE NUMBER OF ANNUAL GROWTH RINGS, SPECIFIC GRAVITY AND TEMPERATURE ON REDWOOD ELASTIC MODULUS

Autor: Nilson T Mascia, Steven M Cramer

Publikováno v: Maderas: Ciencia y Tecnología, Vol 11, Iss 1, Pp 47-60 (2009)

Due to the natural origin of wood, physical parameters such as specific gravity and the number of growth rings per inch affect its properties. In this study, to evaluate the effect that these physical parameters have on the elastic properties of wood

CEPA: A LaBr3(Ce)/LaCl3(Ce) phoswich array for simultaneous detection of protons and gamma radiation emitted in reactions at relativistic energies

Autor: Sánchez del Río J., Mårtensson M., Borge M.J.G., Johansson H., Nilson T., Nácher E., Perea A., Ribeiro G., Tengblad O.

Publikováno v: EPJ Web of Conferences, Vol 66, p 11033 (2014)

A prototype CEPA4, made of four optically isolated phoswich-crystals of LaBr3(Ce)+LaCl3(Ce) packed together in one can of Al, was tested with high energy protons (70-230 MeV) at the cyclotron of Krakow. Further, the response to different gamma radiat

In ISKO 14th Conference, Septembre 2016,, Rio de Janeiro, Brazil, 27-29 Septembre 2016,. [Conference paper]

The current schema used by the Rio de Janeiro`s Museum Network website to classify the museum objects in different museums' collections contains 16 categories that are no longer enough to encompass all the collections of museums about to adhere to th
