Autor: Cristina R. Nascimento, Viviane K. Asfora, Vinicius R. M. Barros, Josemary A. C. Gonçalves, Luiza F. R. Andrade, Helen J. Khoury, Carmen C. Bueno
Publikováno v: Brazilian Journal of Radiation Sciences, Vol 7, Iss 2A (2019)
The response of the commercial XRA-24 PIN photodiode (5.76 mm2 active area) for clinical electron beam dosimetry covering the range of 8-12 MeV was investigated. Within this energy range, the charge generated in the diode’s sensitive volume is line

We developed a global semi-implicit two-time-level semi-Lagrangian model for the atmospheric adiabatic primitive equations discretized through finite-differences, on locally refined grids. The principal aim of the technique is to have high resolution

We analyse several vector reconstruction methods, based on the knowledge of only specific pointwise vector components, and extend their use to non-structured polygonal C-grids on the sphere. The emphasis is on the reconstruction of the vector field a

Analysis of grid imprinting on geodesic spherical icosahedral grids
Autor: Saulo R. M. Barros, Pedro S. Peixoto
Publikováno v: Journal of Computational Physics. 237:61-78
Numerical grid imprinting errors have often been observed in global atmospheric models on icosahedral grids. In this paper we analyse the sources of grid imprinting error related to the usual finite volume discretization of the divergence operator. W

In this paper we analyze the behavior of a family of steady state solutions of a semilinear reaction–diffusion equation with homogeneous Neumann boundary condition, posed in a two-dimensional thin domain with reaction terms concentrated in a narrow

Publikováno v: Veterinary Pathology. 45:542-545
Two cases of patent ductus arteriosus are described in 2 Murrah buffalos, a 7.5-month-old heifer calf and a 5-month-old bull calf. The main clinical signs consisted of exercise intolerance, dyspnea, and tachycardia. At necropsy, lesions were consiste
