Development of the enhanced halsey model to predict equilibrium moisture content (EMC) of sunflower seeds with different oil contents
(American Society of Agricultural and Biological Engineers, 2018-05)Using the right equilibrium moisture content (EMC) relationship is critical for implementing successful aeration strategies and for determining the safe storage moisture content of grains and oilseeds. The oil content of ... -
Diagnosis of sulfur availability for corn based on soil analysis
(Springer Berlin Heidelberg, 2016-10)Different edaphic properties were evaluated to diagnose soil sulfur (S) availability for corn in 15 field experiments as follows: (a) soil sulfate (SO4 −2-S) content at sowing at 0–20 cm and 0–60 cm depths [Sini(0–20) and ... -
Dictyocaulosis in cattle: Retrospective analysis of 20 outbreaks in Central Argentina
(Elsevier, 2024-08)Bovine lungworms (Dictyocaulus viviparus) are nematodes which cause a respiratory disease known as verminous bronchitis or pneumonia. In this paper, we describe 20 outbreaks of bovine dictyocaulosis recorded between 2000 ... -
Differential quality and technical/managerial advice relationships in Andalusian (Spain) olive oil protected designations of origin
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2014-10-21)A relevant topic investigated in ‘Local Agro-Food Systems’ studies (LAFS) is the key role of collective action in the dissemination of innovations and knowledge aimed at the organization of quality on a local scale. The ... -
Dinámica del crecimiento de una pastura de agropiro alargado de acuerdo con la época de fertilización nitrogenada
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2013-08)Las pasturas de agropiro alargado Thinopyrum ponticum (Bark. y Dewey) en la Pampa Deprimida bonaerense, en términos generales, son considerados cultivos con pobre producción de forraje, de escaso valor nutricional para la ... -
Dinámicas sociodemográficas y sistema de asentamientos en el sudeste bonaerense. Un análisis comparado entre General Pueyrredon y Balcarce (1991-2010)
(Centro de Investigaciones Geográficas, Facultad de Ciencias Humanas, Universidad Nacional del Centro de la Provincia de Buenos Aires, 2021-05)El objetivo de este trabajo es analizar las características sociodemográficas de la población de los partidos de General Pueyrredon y Balcarce, entre 1991 y 2010. En base a los datos de los Censos Nacionales de Población, ... -
Distinctive features of bovine alphaherpesvirus types 1 and 5 and the virus-host interactions that might influence clinical outcomes
(Springer, 2019-12-16)Bovine herpesvirus types 1 (BoHV-1) and 5 (BoHV-5) are two closely related alpha-herpesviruses. BoHV-1 causes several syndromes in cattle, including respiratory disease and sporadic cases of encephalitis, whereas BoHV-5 ... -
Distribución local de alimentos en tiempos de pandemia
(Asociación Argentina de Horticultura, 2021-04)A partir del primer caso de infección de COVID-19, el Estado Argentino implementó el 20 de marzo de 2020 el régimen de Aislamiento Social, Preventivo y Obligatorio (ASPO). Este aislamiento no incluía a los actores sociales ... -
