Complexo quadrático de retas
(Universidade Federal de Minas GeraisUFMG, 2007-04-16)
On studying the Grassmanian of lines in projective space and Plücker's Quadric related to it, we noted the presence of interesting congurations of lines. From those congurations, a surface in projective space, the so called ...
Sedimentological, geochemical and paleontological insights applied to continental omission surfaces: A new approach for reconstructing an eocene foreland basin in NW Argentina
(Pergamon-Elsevier Science Ltd, 2010-03)
An Eocene foreland basin linked to the Andean uplift in northwestern Argentina has recently been proposed. The basin is divided and partially eroded due to subsequent Neogene orogenic phases, so that a simple reconstruction ...
Applied hydrodynamic wave-resistance computation by Fourier transform
(Pergamon-Elsevier Science Ltd., 2002-12)
An applied Fourier transform computation for the hydrodynamic wave-resistance coefficient is shown, oriented to potential flows with a free surface and infinity depth. The presence of a ship-like body is simulated by its ...
Assembly, organization and regulation of cell-surface receptors by lectin–glycan complexes
(Portland Press, 2015-06)
Galectins are a family of β-galactoside-binding lectins carrying at least one consensus sequence in the carbohydrate-recognition domain. Properties of glycosylated ligands, such as N- and O-glycan branching, LacNAc ...
Surface depletion and electrical transport model of AlInP-passivated GaAs nanowires
(Iop Publishing, 2013-09)
Fabrication, current-voltage characterization and analytical modeling of an AlInP-passivated GaAs nanowire (NW) ensemble device are presented. During fabrication, sonication was used as a novel and crucial step to ensure ...
A world key to the species of Pyxine with lichexanthone, with a new species from Brazil
(Cambridge Univ Press, 2014-09-01)
A world key is given to the species of Pyxine with lichexanthone in the upper cortex. Pyxine pustulata Aptroot & Jungbluth is described as a new corticolous species of Pyxine from Sao Paulo State in Brazil, with lichexanthone ...
Hydroxyapatite surface solubility and effect on cell adhesion
(Elsevier Science BvAmsterdamHolanda, 2010)
Redescription of Tuarangisaurus keyesi (Sauropterygia; Elasmosauridae), a key species from the uppermost Cretaceous of the Weddellian Province: Internal skull anatomy and phylogenetic position
(Academic Press, 2017)
© 2016 Elsevier Ltd The systematics of elasmosaurids are not well resolved partially because of the scarcity of well-preserved skull material. Among Weddellian elasmosaurids, one exception to this is the holotype of ...
