Effects of water erosion in road Embankments
(2015)
Road projects are linear works that affect various geotechnical and
hydrological environments. In these projects, the interaction of local soils with
water draining superficially, or inside embankments, should be assessed ...
3D hydrodynamic modelling to optimize the hydraulic efficiency of the weirs and turbines intakes of the Néstor Kirchner dam in Santa Cruz, Argentina
(2015)
In this work 3D hydrodynamic modeling were performed on the weir channel access and the turbines
intakes of Nestor Kirchner dam in the province of Santa Cruz (Argentina). Different alternatives of the
layout scheme of ...
Forecasting noisy time series approximated by neural networks
(2014)
In this work, a proposed methodology for univariate noisy time series prediction
approximated by artificial neural networks (ANN) is applied to the problem of forecasting
monthly rainfall precipitation in Cuesta El ...
Callothrix clavata development W.G.S. in soil treated with herbicide atrazine at agronomic rate
(2015)
More than 70% of agricultural tillage in Argentina is made as direct seeding,
so weed control is done primarily with the application of herbicides. Atrazine (2-
chloro-4-ethylamino-6-isopropylamino-s-triazine) is one of ...
Effects of prenatal ethanol exposure on hidroelectrolyte homeostasis
(2014)
The aim of the present work was to analyze the effect of prenatal exposure to moderate
doses of ethanol (Pre-EtOH) during the gestational days (GD) 17 to 20 on offspring
(postnatal day 28-33) hydroelectrolyte balance. ...
Watermarking based on difference expansion and genetic algorithms
(2015)
Security problems that recently appeared in transmission and storing of digital content can be solved by using watermarking. Reversible watermarking is the election in medical and defense imagery because these security ...
Corticosteroid receptor immunoreactivity in neurons of the hippocampus, amygdala and paraventricular nucleus, in rats under maternal separation and chronic stress: Effects of tianeptine
(2014)
Hippocampus, amygdala and paraventricular nucleus of hypothalamus (PVN), which belong to the reward system, widely express Gluco- and mineralo- corticoid receptors (GR and MR, respectively) and are critically involved in ...
Expression or not of Dpp two different populations of growing cells in Drosophila
(2014)
Dpp is a growth factor that induces growth in relation with its absolute celular amount (Martín-Castellano and Edgar, 2002). However, there is other evidence respect to the growth function of Dpp that is to repress a ...
Determination of atrazine in environmental samples (soil and water) by UHPLC-MS/MS
(2013)
Atrazine is an extensively used herbicide in Argentina. It solubility in water is 30 mg/L and the average half life in underground waters is of 283 days. It moderate solubility and stability led to the findings of residues ...
Behavior of collapsible loess saturated with NAPL in confined compresion tests
(2015)
Loess from the central area of Argentina are unstable soils with mechanical properties highly dependent on moisture content. These soils have a macro skeleton that collapses when either loads increase and/or water enter ...
