Glyphosate and AMPA concentrations in wind-blown material under field conditions
(John Wiley & Sons Ltd, 2018-05)
Agricultural intensification in fragile arid and semiarid environments has led to an increase in soil degradation, mainly through wind erosion. Argentina is an agricultural and cattle-farming country, which has increased ...
Carrier systems for yerba mate extract (Ilex paraguariensis) to enrich instant soups. Release mechanisms under different pH conditions
(Elsevier Science, 2013-09)
The high antioxidant properties of yerba mate (Ilex paraguariensis) extract make it suitable as a natural food additive. Encapsulation of herbal extracts is often necessary to enhance handling and product stability. Release ...
Sublimation of icy planetesimals and the delivery of water to the habitable zone around solar type stars
(Wiley Blackwell Publishing, Inc, 2018-09)
We present a semi-analytic model to evaluate the delivery of water to the habitable zone (HZ) around a solar type star carried by icy planetesimals born beyond the snow line. The model includes sublimation of ice, gas drag, ...
Bajada del Diablo impact crater-strewn field: The largest crater field in the Southern Hemisphere
(Elsevier Science, 2009-08)
Recent remote sensing analyses and field studies have shown that Bajada del Diablo, in Argentina, is a new crater-strewn field. Bajada del Diablo is located in a remote area of Chubut Province, Patagonia. This amazing ...
Threshold wind velocity as an index of soil susceptibility to wind erosion under variable climatic conditions
(John Wiley & Sons Ltd, 2009-12)
Wind erosion starts when the threshold wind velocity (μ t ) is exceeded. We evaluated the sensitivity of μ t to determine the wind erosion susceptibility of soils under variable climatic conditions. Three years field data ...
Acceso al sistema educativo de la población urbana argentina, 2001-2010Access to educational system of Argentina's urban population., 2001-2010
(Universidad Nacional de Lanús, 2015-12)
El ejercicio que presentamos en este trabajo se inserta en el debate reciente sobre el impacto de determinadas políticas públicas en el acceso de la población al sistema educativo. Se busca una aproximación a la forma en ...
From leaf traits to agroecosystem functioning: effects of changing resource use strategy during silphium domestication on litter quality and decomposition rate
(Springer, 2022-02)
Aims: We asked if structural and chemical changes in leaf traits, brought about by early domestication in perennial Silphium integrifolium Michx. (Asteraceae), have influenced litter quantity and quality, and decomposition ...
Nuevos desafíos para la rendición de cuentas en tiempos de pandemia: populismo y algoritmocraciaNew challenges for accountability in times of the pandemic: populism and algorithmocracy
(Universidad Nacional Autónoma de México, 2021-05)
Este artículo presenta al populismo y a los siste-mas de inteligencia artificial como dos procesos que desafían y cuestionan el funcionamiento de la red institucional de rendición de cuentas en las democracias representativas. ...
Effect of “Whitemouth Croaker” (Micropogonias furnieri, Pisces) on the Stability of the Sediment of Salt Marshes—an Issue To Be Resolved
(Springer, 2017-03)
Among the predators, fish are prevalent in intertidal soft-bottom zones, and many create substantial interruptions in the sediment surface through their feeding, thus affecting the movement of fluids in the sediment-water ...
Tracing sediment sources in an agriculture and livestock catchment of Argentina through the use of geochemical fingerprints
(International Atomic Energy Agency (IAEA), 2019-01)
A mixing modelling approach (CSSIAR v2.00), using Energy Dispersive X Ray Fluorescence (EDXRF) and Total Organic Carbon (TOC) data as fingerprints for sediment sources and sinks, was applied for identifying critical hot ...
