Medición de cationes intercambiables en suelos afectados por sales de la Región Semiárida Pampeana
(Asociación Argentina Ciencia del Suelo, 2023-06)La determinación de cationes intercambiables en suelos salinos y/o sódicos, por extracción con acetato de amonio, no permite distinguir las proporciones de cationes intercambiables de sus formas solubles. Para cuantificar ... -
Meteorological conditions during dust (PM10) emission from a tilled loam soil: Identifying variables and thresholds
(Elsevier, 2017-10-15)Soil wind erosion and consequent PM10 emission is a complex process that has been related to surface properties and meteorological conditions. Most of the studies have emphasized on the relationship between the surface ... -
Microbiological quality, fungal diversity and aflatoxins contamination in carob flour (Prosopis flexuosa)
(Elsevier, 2020)Carob flour is obtained from pods of some species of Prosopis, leguminous trees that abound in many desert habitats worldwide. Currently, this product is available in healthy food stores in several countries, including ... -
Molecular characterization and phylogenetic assessment of agricultural-related noctuids (Lepidoptera: Noctuidae) of South America
(Sociedade Brasileira de Entomologia, 2021-12-13)Accurate identification of species is fundamental to every biological research. While morphological identification is a time-consuming and skilled technique, straightforward molecular techniques require the availability ... -
Morfometría de la cuenca alta del Río Colorado, Argentina = Morphometric of the Colorado River high basin, Argentina
(Universidad Nacional del Comahue. Neuquén. Departamento Geografía, 2018)Las subcuencas del río Grande y del río Barrancas conforman la cuenca alta del río Colorado y la abastecen de agua a partir de la nieve que precipita en las altas cumbres. Conocer las características morfométricas y ... -
Multiparametric analysis and authentication of Argentinian vinegars from spectral sources
(Elsevier, 2024-01)Ultraviolet-visible (UV-Vis) and near infrared (NIR) spectroscopies allied to chemometrics were investigated for quality control and authentication of Argentinean wine and balsamic vinegars. First, a multiparametric approach ... -
Occurrence of powdery mildew disease in wheat fertilized with increasing silicon doses: a chemometric analysis of antioxidant response
(Springer, 2016-08)Blumeria graminis (Bgt) is a pathogenic fungus that affects severally wheat plants provoking high losses in wheat production. Biochemical parameters like enzyme activity of catalase, superoxide dismutase, or peroxidases ... -
