1. Shadow of the Moon and general relativity: Einstein, Dyson, Eddington and the 1919 light deflection
Abstract The eclipse of the Sun of 1919 was fundamental in the development of physics and earns a high place in the history of science. Several players took part in this adventure. The most important are Einstein, Dyson, Eddington, the Sun, the Moon, Sobral, and Principe. Einstein's theory of gravitation, general relativity, had the prediction that the gravi

2. Máscaras mecânicas de sombra por eletrocorrosão para dispositivos eletro-ópticos
Shadow masks are used in manufacturing processes for electro-optic devices to transfer patterns with different shapes and dimensions. For fabrication of organic based devices, shadow masks should be made of materials stable against organic solvents, high temperature, and robust, remaining unchanged after multiple cycles of use and fixation. Thus, stainless s

6. Ecophysiological studies of two andean forest contrasting species Abatia parviflora and Myrcianthes leucoxyla under Bogotá conditions, Colombia
The physiological response of high Andean forest contrasting plants, Myrcianthes leucoxyla, a shadow-facultative heliophyte, and Abatia parviflora, a heliophyte, was studied during the transition from dry season to wet season in Bogotá. Light response curves (A-PAR), water potential (Ψw), transpiration rate (E), stomatal conductance (gs), leaf soluble prot

7. Effects of the overshadow availability at pasture on the reproductive characteristics in Nelore Bulls / Efeitos da disponibilidade de sombra na pastagem sobre as características reprodutivas de touros da raça Nelore
It is known that heat stress is the main cause that affects bulls reproductive performance, consequently leaded to testicular degeneration. This pathologic alteration can also occur in Bos Indicus cattle. The objective of this experiment was verify the shadow availability effect at pasture on reproductive characteristics in Nelore, a Bos Indicus bull. For th

11. GERAÇÃO DE SOMBRAS EM TEMPO REAL PARA MODELOS CAD / REAL-TIME SHADOW MAPPING TECHNIQUES FOR CAD MODELS
O mapeamento de sombras é uma técnica de renderização amplamente utilizada para a geração de sombras de superfícies arbitrárias em tempo real. No entanto, devido a sua natureza amostrada, apresenta dois problemas de difícil resolução: o aspecto chamuscado de objetos e a aparência serrilhada das bordas das sombras. Em particular, o sombreamento de

12. DEVELOPMENT OF TECHNIQUE BASED ON FLUORESCENCE TO MEASURE TWOPHASE SLUG FLOW / DESENVOLVIMENTO DE TÉCNICA BASEADA EM FLUORESCÊNCIA PARA MEDIÇÃO DE ESCOAMENTO BIFÁSICO EM REGIME DE GOLFADA
This work presents the implementation of a non-intrusive optical technique for measuring the hydrodynamic characteristics of liquid- gas, two-phase flows. The work was limited to the study of air-water slug flows. The technique implemented, already described in the literature, combines Particle Image Velocimetry - PIV, Laser Induced Fluorescence - LIF, and p
