TEACHER EDUCATION IN ASTRONOMY: AN ANALYSIS OF THE BANK OF THESES AND DISSERTATIONS ON EDUCATION IN ASTRONOMY
(Univ Francisco Jose Caldas, Fac Science & Education, 2021-09-01)
This research intends to present the mapping of theses and dissertations related to the theme of Teacher Education in Astronomy made available at the Bank of Theses and Dissertations on Education in Astronomy. In the data ...
Elastic instability of grain boundaries and the physical origin of superplasticity
(American Inst of Physics, 2000)
The dependence of the superplastic flow on the efficiency of grain boundaries for capturing and releasing vacancies is demonstrated. It is emphasized that this flow is dependent mostly on the sensitivity of this ability ...
From the scale model of the sky to the armillary sphere
(American Association of Physics Teachers American Institute of Physics, 2014-10)
It is customary to employ a semi-spherical scale model to describe the apparent path of the Sun across the sky, whether it be its diurnal motion or its variation throughout the year. A flat surface and three bent semi-rigid ...

Two-color discrete localized modes and resonant scattering in arrays of nonlinear quadratic optical waveguides
(2005)
We analyze the properties and stability of two-color discrete localized modes in arrays of channel waveguides where tunable quadratic nonlinearity is introduced as a nonlinear defect by periodic poling of a single waveguide ...
Firing sequence storage using inhibitory synapses in networks of pulsatil nonhomogeneous integrate-and-fire neural oscillators
(2002)
We discuss a nonhomogeneous population of pulsatil integrate-and-fire neural oscillators, coupled through purely inhibitory synapses. For instantaneous communication, we provide a strategy to generate synaptic couplings ...
Stationary convection in a cylindrical plasma
(1994)
It is shown that in a current-carrying cylindrical plasma with a free boundary, viscosity and thermal conductivity can lead to large scale steady convection. The physical situation is identical to the case when the plasma ...
Structure of liquid GeO2 from a computer simulation model
(2004)
The structural properties of liquid GeO2 were investigated using molecular dynamics simulation. A comparison of the obtained pair correlation functions, coordination number, angular distribution, and both the neutron and ...
