Análisis morfométrico de cenizas volcánicas por microscopía holográfica digitalMorphometric análisis of vulcanic ashes by digital holografic microscopy
(Asociación Física Argentina, 2020-04)
Las cenizas volcánicas presentan formas, texturas y tamaños altamente irregulares. Estas características influyen en su comportamiento aerodinámico, velocidad de sedimentación y dispersión, distancias de desplazamiento, ...
Trace fossils of cicadas in the Cenozoic of Central Patagonia, Argentina
(Wiley Blackwell Publishing, Inc, 2008-03)
Hemispherical pan or dish-shaped trace fossils from the Cenozoic of the Central Patagonia are attributed to the burrowing action of cicadas. A new ichnotaxon, Feoichnus challa igen. et isp. nov. is characterized by its ...
Ultrastructure and morphometry of the egg of Psorophora albipes (Theobald, 1907) (Diptera: Culicidae)
(Magnolia Press, 2017-09)
The eggs of Psorophora albipes were studied using scanning electron microscopy (SEM) and described based on a morphometric analysis of the main structures observed. We used eggs from a female caught in the Poço das Antas ...
Ornithodoros quilinensis sp. nov. (Acari, Argasidae), a new tick species from the Chacoan region in Argentina
(Versita, 2012-09)
Ornithodoros quilinensis sp. nov. (Acari: Argasidae) is described from larvae collected on the small rodents Graomys centralis (Cricetidae: Sigmodontinae) in Argentina. The diagnostic characters for this new species are a ...
A microstructure-level study of monoglycerides oleogels using rheomicroscopy
(The American Oil Chemists' Society, 2017)
Monoglycerides oleogels are semisolid systems containing self-assembled structures formed by crystalline material entrapping liquid oil in a three-dimensional network. The microstructure of the network of these oleogels ...
A global database of composite volcano morphometry
(Springer, 2014-01)
We present a global database on the subaerial morphometry of composite volcanoes. Data was extracted from the 90 m resolution Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM). The 759 volcanoes included ...
Size-controlled nanopores in lipid membranes with stabilizing electric fields
(Academic Press Inc Elsevier Science, 2012-06)
Molecular dynamics (MD) has been shown to be a useful tool for unveiling many aspects of pore formation in lipid membranes under the influence of an applied electric field. However, the study of the structure and transport ...
Strickly finite-range potential for light and heavy nuclei
(American Physical Society, 2014-05)
Strictly finite-range (SFR) potentials are exactly zero beyond their finite range. Single-particle energies and densities, as well as S-matrix pole trajectories, are studied in a few SFR potentials suited for the description ...
