Pest control treatments with phosphine and controlled atmospheres in silo bags with different airtightness conditions
(2016)La tecnología de bolsas de silo ha sido ampliamente utilizada en Argentina para almacenar granos (por ejemplo, trigo, maíz, cebada, girasol y soja, entre otros) desde mediados de los años noventa. Bolsa de silo son ampliamente ... -
Pesticide pollution in argentine drinking water: A call to ensure safe access
(Elsevier, 2024-01)The application of pesticides in Argentina has been on the rise since 2000. However, the monitoring of pesticides in drinking water lacks regular updates. This research study analysed 53 pesticides and degradation products ... -
Pérdidas de nitrógeno por volatilización y eficiencia de uso en maíz desde urea aplicada en diferentes momentos
(Ediciones INTA, 2023-06)La volatilización de amoníaco (N-NH3) es una importante vía de pérdida de nitrógeno (N) desde fertilizantes nitrogenados. En tal sentido, existe la necesidad de desarrollar estrategias de manejo que maximicen la eficiencia ... -
Phenotypic characterisation of the cellular immune infiltrate in placentas of cattle following experimental inoculation with Neospora caninum in late gestation
(BMC, 2013-07)Despite Neospora caninum being a major cause of bovine abortion worldwide, its pathogenesis is not completely understood. Neospora infection stimulates host cell-mediated immune responses, which may be responsible for the ... -
Phenotypic characterization of immune cells in fetal tissues of cattle immunized and challenged with Neospora caninum
(Elsevier, 2019-11)The purpose of this work was to characterize the cellular phenotype in inflammatory infiltrates of fetal tissues from pregnant heifers immunized and experimentally challenged with Neospora caninum. Fetuses from 20 heifers ... -
Phosphorus placement effects on phosphorous recovery efficiency and grain yield of wheat under no-tillage in the Humid Pampas of Argentina
(2014)No-till (NT) affects dynamics of phosphorus (P) applied. Wheat response to P fertilization can be affected by available soil P, grain yield, placement, rate, and timing of fertilization. Furthermore, mycorrhizal associations ... -
Physicochemical parameters and sensory properties of honeys from Buenos Aires region
(Elsevier, 2014-06-01)The physicochemical parameters (moisture, hydroxymethyl furfural, colour, electrical conductivity, free acidity, glucose, fructose and sucrose) and the sensory properties(aroma, taste, appeareance, texture) were determined ... -
