Least square based method for the estimation of the optical end loss of linear Fresnel concentrators
(Elsevier, 2015-01)
Small-scale solar concentrators based on linear Fresnel (LFC) are a promising technology for domestic and industry applications. In such short systems, optical end losses and their influence on the energy performance are ...
Aspects of stellar atmospheres and star formation
(Universidade Federal de Minas GeraisUFMG, 2000-07-05)
We initially investigate some processes that affect the stellar atmosphere, such as the gravity-brightening and limb-darkening, and the influence of the reflection effect on them. We study the gravity-brightening exponents ...
Olive floral development in different hedgerow positions and orientations as affected by irradiance
(Elsevier, 2017)
Irradiance received within the olive hedgerow canopy varies with respect to row orientation, spacing and hedge dimensions. These orchard management criteria offer the opportunity for improving productivity based on ...
Differential response to photoperiod by diverging Rhagoletis pomonella (Diptera: Tephritidae) populations exploiting host plants with different fruiting phenology
(Sociedade Entomológica do Brasil, 2019-06)
Photoperiod has been found to influence the proportion of non-dormant individuals and the duration of dormancy among North American populations of Rhagoletis pomonella (Walsh) (Diptera: Tephritidae). In particular, long ...
Lensometry by two-laser holography with photorefractive Bi12TiO20
(American Institute of Physics (AIP), 2008-05-21)
Refractive and profilometric measurements of lenses were performed through holography with a photorefractive Bi12TiO20 crystal as the recording medium. Two properly aligned diode lasers emitting in the red region were ...
Spot-beam effect in grazing atom-surface collisions: From quantum to classical
(IOP Publishing, 2018-10)
Grazing incidence fast atom diffraction (GIFAD) is a sensitive tool for surface analysis, which strongly relies on the quantum coherence of the incident beam. In this article we study the spot-beam effect, due to contributions ...
