Phonon contribution in grazing-incidence fast atom diffraction from insulator surfaces
(American Physical Society, 2019-12)
We study the effect of crystal lattice vibrations on grazing-incidence fast atom diffraction (GIFAD) from insulator surfaces. To describe the phonon contribution to GIFAD we introduce a semiquantum method named phonon-surface ...
Energy and electron spectra after grazing- ion-surface collisions
(American Physical Society, 2002-12)
For ions that impinge grazing on solid surfaces, binary collisions with the free-electron gas are investigated by means of a modified specular-reflection (MSR) model. The proposed MSR theory is applied to the calculation ...
Electron emission in grazing-ion-surface collisions
(American Physical Society, 2000-12)
For ions impinging grazingly on a solid surface, the electron emission from the inner shells of solid atoms is investigated by employing a semiclassical formalism. The emission rate is expressed in terms of probabilities ...
Multiple beam interference with near-grazing waves in dielectric wedges: polarization dependence

Grazing angle photoluminescence of porous alumina as an analytical transducer for gaseous ethanol detection
(American Scientific Publishers - ASPValencia, 2014-09)
Porous alumina was used to build an optical sensor for gaseous ethanol detection. The photoluminescence collected in a grazing angle was used as a transducer signal. The photoluminescence detected with this optical setup ...
Phenomena and characterization of grazing-sliding bifurcations in aeroelastic systems with discontinuous impact effects
(2015-12-08)
Impacts are present in real aircraft movable surfaces, such as ailerons, flaps, rudder, elevators, trim tabs among other secondary control surfaces leading to complex, dangerous, and abrupt transitions. In this research ...
Estrutura do dossel e acúmulo de forragem de Brachiaria brizantha cultivar Xaraés em resposta a estratégias de pastejo.
(Pesquisa Agropecuária Brasileira, Brasília, v.42, n. 2, p.281-287, fev. 2007., 2014)
High resolution, large spectral range, in variable-included-angle soft X-ray monochromators using a plane VLS grating
(Elsevier Science BvAmsterdamHolanda, 2005)
Estratégias de manejo do pastejo para Panicum maximum cvs. Quênia e Tamani
(Universidade Federal de Mato GrossoBrasilInstituto de Ciências Agrárias e Ambientais (ICAA) – SinopUFMT CUC - CuiabáPrograma de Pós-Graduação em Zootecnia, 2016-12-05)
The objective of this study was to evaluate grazing management strategies and physiological
characteristics for Panicum maximum cvs. Quênia and Tamani under different intensities of
grazing and often defined by 95% light ...
