Study of the potential of irregular shaped bodies and orbits around a non-spherical body
(2007-12-01)
In the present work we show the expressions of the gravitational potential of homogeneous bodies with non-spherical three-dimensional shapes in order to study the trajectories around these bodies. The potentials of a prolate ...

Influência de tanques-rede na comunidade fitoplanctônica e na qualidade da água em um reservatório tropical: avaliação em duas dimensões espaciais
(Universidade Federal de Minas GeraisUFMG, 2015-02-13)
This study aims to evaluate the effects of fish cages on water quality of a large tropical reservoir. We have studied the impacts by obtaining samples along two spatial dimensions (horizontal and vertical) in the vicinity ...
Highly symmetrical crystallization in six rectilinear and well-defined axes found in bovine cervical mucus obtained at oestrus: a finding. artículo corto
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2014-07-30)
Bovine cervical mucus (BCM) is important for selection and transport of spermatozoa. When air-dried, BCM obtained at oestrus exhibits arborescent crystallizations, among other arrangements. Considering the relevant endocrine ...
Major Words in the History of Kings, Infantes and Navigators
(Univ Federal Rio De Janeiro, 2018-09-01)
In Portugal in the 15th century, chronicles and travel accounts dedicated both to the past of the kingdoms and to the ever-deeper incursions into African lands are structured around certain general ideas, like ordering, ...
Three-dimensional modeling of pavement with dual load using finite element
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-01-01)
The model developed tries to predict the stresses and strains of the structure of the pavement in a more real way, doing a lineal elastic structural analysis in three dimensions with capacity to model loads of double axes, ...
Late cenozoic tectonics and paleomagnetism of North Cauca Basin intrusions, Colombian Andes: Dual rotation modes
(ELSEVIER SCIENCE BV, 1996-09-15)
Further paleomagnetic results are reported from 18 sites in Late Tertiary hypabyssal igneous rocks adjacent to the Romeral fault system which forms the eastern boundary of the North Cauca Basin. The paleomagnetic directions ...
