Power flow in distribution networks with earth return
(Elsevier B.V., 2004-06-01)
The problems of wave propagation and power flow in the distribution network composed of an overhead wire parallel to the surface of the ground have not been satisfactorily solved. While a complete solution of the actual ...

Fundamentos conceituais da determinação do geóide pelo método gravimétrico
(Universidade Federal de Santa MariaBRGeociênciasUFSMPrograma de Pós-Graduação em Geomática, 2007-03-30)
Fundamental concepts of gravimetric geoid determination with the objective to didatic methodology. It s described that the study of the real Earth have a large number of variable, what becomes impracticable the problem ...
Static earth pressures on a pile supported excavation in Santiago gravel
(2019)
Concrete soldier piles anchored in multiple levels are the most common method for supporting deep excavations in gravel. Their static design is based on limit equilibrium principles, although these procedures were originally ...
Natural formations at the Earth-Moon triangular point in perturbed restricted problems
(Elsevier B.V., 2015-07-01)
Previous studies for small formation flying dynamics about triangular libration points have determined the existence of regions of zero and Minimum Relative Radial Acceleration with respect to the nominal trajectory, that ...
Investigation on extraction rate of lanthanides with extractant-impregnated microcapsule
(ELSEVIER, 2008-05-15)
Extraction of lanthanum, samarium and erbium into a microcapsule containing 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester (EHPNA) is studied. The extraction kinetic model used to predict uptake curves is based on the ...
Observed crustal uplift near the Southern Patagonian Icefield constrains improved viscoelastic Earth model
(American Geophysical Union, 2014-02)
Thirty‒one GPS geodetic measurements of crustal uplift in southernmost South America determined extraordinarily high trend rates (> 35 mm/yr) in the north‒central part of the Southern Patagonian Icefield. These trends have ...
Experimental and theoretical study of the behavior of hydrogen in rare earths
(Pergamon-Elsevier Science Ltd, 2005-05-13)
In this work, we study the behavior of hydrogen in some rare earths lanthanum (La), cerium (Ce), lutetium (Lu), and in two of its chemical precursors, scandium (Sc) and ytrium (Y). In the experimental aspect, samples of ...
