Chromatographic matrix based on hydrogel-coated reticulated polyurethane foams, prepared by gamma irradiation
(Pergamon-Elsevier Science Ltd, 2017-12)
Novel chromatographic materials for protein purification with high adsorption capacity and fouling resistance are highly demanded to improve downstream processes. Here, we describe a novel adsorptive material based on ...
De la política de la lengua a la lengua de la política: cartas guaraníes en la transición de la colonia a la era independienteFrom the Policy of Language to theLanguage of Politics.Guarani Letters of the Transition from the Colony to the Independent Era
(Diego Escolar, 2014-06)
Este artículo presenta un corpus de documentos guaraníes del ámbito de las reducciones jesuíticas del Paraguay, en su mayoría escritos por líderes indígenas. Los documentos cubren el período 1768-1831, es decir, desde la ...
Spray drying formulation of albendazole microspheres by experimental design. In vitro–in vivo studies
(Taylor & Francis, 2013-11)
Both an experimental design and optimization techniques were carried out for the development of chitosan–pectin–carboxymethylcellulose microspheres to improve the oral absorption of albendazole as a model drug. The effect ...
Spray-Dried Cascara sagrada Extract for Direct Compression: Tablet Formulation and a Simple HPLC Method for Tablet Performance Evaluation
(International journal of research in pharmaceutical and biomedical sciences, 2013-12)
Cascara sagrada bark is extensively used in the treatment of occasional constipation. Despite its wide diffusion, Cascara sagrada dried extracts with good flow and compactability properties for tablet formulation by direct ...
Modeling the influence of MgSO4 invariant points on multiphase reactive transport process during saline soil evaporation
(Elsevier, 2013-01)
In the present work, we modeled a laboratory experiment where a sand column saturated with a MgSO4 solution is subject to evaporation. We used a compositional formulation capable of representing the effect of geochemistry ...
Light acidification in N-fertilized loess soils along a climosequence affected chemical and mineralogical properties in the short-term
(Elsevier Science, 2015-12)
Some evidences indicate that N-fertilization of crops decreased pH values of loess soils of the Argentinean Pampas in the last decades. We analyzed the A-horizons of four N-fertilized (F) and non-fertilized (NF) paired ...

In situ study of the endotaxial growth of hexagonal CoSi2 nanoplatelets in Si(001)
(American Institute of Physics, 2015-11)
This investigation aims at studying-by in situ grazing-incidence small-angle x-ray scattering-the process of growth of hexagonal CoSi2 nanoplatelets endotaxially buried in a Si(001) wafer. The early formation of spherical ...
