Uncoupled evolution of male and female cone sizes in an ancient conifer lineage
(University of Chicago Press, 2019-01)
Sexual functions in gymnosperms are mostly performed by separate reproductive structures, which largely reduces sexual interference and sets the scene for morphological and functional sexual specialization. The evolutionary ...
Accuracy assessment of prototypes using multi-slice and cone beam computed tomography
(Elsevier Ltd., 2012)
The objective of this study was to assess and quantify the dimensional error of prototypes produced using multi-slice and cone-beam computed tomography(MSCT and CBCT). Titanium screws were inserted into a dry skull at ...

Post-caldera pumice cones of the Payún Matrú caldera, Payenia, Argentina: Morphology and deposits characteristics
(Pergamon-Elsevier Science Ltd, 2019-03)
The formation of pumice cones by deposition of near-vent pumice fragments is relatively rare in comparison with the occurrence of their mafic equivalents, the scoria cones. The Quaternary Payún Matrú caldera (36° S, 69° ...

Imagen de hipertrofia bilateral del proceso coronoides mandibular a través de la tomografía computarizada cone-beam
(2012)
The hypertrophy of the mandibular coronoid process is a rare condition, progressive and of unknown etiology, characterized by the over development of the coronoid process determining their size increased, resulting in ...
Dynamics of developable cones under shear
(2004)
We identify and study a persistent structure characteristic of the post-buckling regime of a thin cylindrical shell subjected to axial torsion. It consists of a pair of developable cones ( d cones) joined by an S-shaped ...
