Runoff and Sediment Transport in the Arid Regions of Argentina and India: A Case Study in Comparative Hydrology
(Winand Staring Centre for Integrated Land, Soil and Water Research, 1996-06)
The arid zones of Argentina and India have been compared. In both regions run-off is often generated by the Hortonian infiltration surplus overland flow, and run-off response to precipitation input tends to be rapid. The ...
RWEQ wind erosion predictions for variable soil roughness conditions
(2016)
The soil surface is a main factor in all wind erosion prediction models including the Revised Wind Erosion Equation (RWEQ). The objetive of this study was to test the erodibility of two typical soils of the semiarid ...
Accretion of galaxy groups into galaxy clusters
(Wiley Blackwell Publishing, Inc, 2020-11)
We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼1014 M from the cosmological hydrodynamical simulation Illustris and follow their ...
Dust evolution in galaxy cluster simulations
(Wiley Blackwell Publishing, Inc, 2018-09)
We implement a state-of-the-art treatment of the processes affecting the production and Interstellar Medium (ISM) evolution of carbonaceous and silicate dust grains within SPH simulations. We trace the dust grain size ...
El impacto de la crisis internacional sobre la economía argentina
(Univesidad de Costa Rica. Facultad de Ciencias Económicas, 2011-06)
El trabajo analiza el impacto de la crisis financiera internacional de 2008 sobre la economía argentina desde la perspectiva del sector externo. Siguiendo el enfoque de algunos expertos, la hipótesis que se plantea es que ...
Global decline of bumblebees is phylogenetically structured and inversely related to species range size and pathogen incidence
(The Royal Society, 2017-07-19)
Conservation biology can profit greatly from incorporating a phylogenetic perspective into analyses of patterns and drivers of species extinction risk. We applied such an approach to analyse patterns of bumblebee (Bombus) ...
Paisajes, vidas y equivocaciones en los Andes Meridionales (Jujuy, Argentina)Landscapes, lives and equivocations in Southern Andes (Jujuy, Argentina)
(Universidad de Tarapacá. Facultad de Ciencias Sociales y Jurídicas. Departamento de Antropología, 2018-10)
En este trabajo presentamos algunas reflexiones que ponen a la noción de paisaje en variación, considerando las formas equívocas (sensu Viveiros de Castro 2004), desde las cuales puede ser pensada y constituida. A partir ...
Enhanced weathering and erosion of a cohesive shore platform following the experimental removal of mussels
(Frontiers Media, 2021-10)
The organisms inhabiting intertidal platforms can affect their weathering and erosion rates. Research on biotic influences on platform integrity has traditionally emphasized the role of bioeroders (i.e., organisms that ...
Modeling of dispersed-drug delivery from planar polymeric systems: Optimizing analytical solutions
(Elsevier Science, 2010-11)
Analytical solutions for the case of controlled dispersed-drug release from planar non-erodible polymeric matrices, based on Refined Integral Method, are presented. A new adjusting equation is used for the dissolved drug ...
Brechas intraclásticas (tsunamitas?) en el tope de la Formación San Juan (Darriwiliano), Precordillera de San Juan, Argentina: Microfacies y ConodontesIntraclastic breccias (tsunamites) on the top of San Juan Formation (Darriwilian), San Juan Precordillera, Argentina: Microfacies and Conodonts
(Instituto Superior de Correlación Geológica, 2011-07)
Se describen por primera vez niveles de brechas intraclásticas en el último metro de la Formación San Juan, Precordillera Central (San Juan-Argentina). Las características microfaciales, relaciones litofaciales y las ...
