Adsorptive filter for the removal of arsenic in drinking water
(2014)The presence of arsenic in water used for human consumption is a widespread problem in several regions around the world. Cordoba Province at the center of Argentine has aquifers that naturally contain As and are the main ... -
Antioxidant activity of monoterpenes and synergist antioxidant effect with BHT
(2014)Synthetic antioxidants are used in many foods. Their health safety is questioned. Monoterpenesobtained from essential oils have shown antioxidant activity. The objective of this study was to evaluate the preserving effect ... -
Asbestiform amphiboles in a marble quarry: A case study from the province of Córdoba (Argentina)
(2014)Pure and impure marbles in Argentina have been exploited for hundreds of years for different purposes. Marble processing is varies depending on its use and could include chemical treatments, burning, crushing, milling ... -
Correlación entre las propiedades estructurales y la adhesión bacteriana de biomateriales compósito de titanio-hidroxiapatita
(2014)El éxito de los biomateriales, particularmente para implantes y prótesis óseas, se basa en preparar dispositivos cuyas superficies sea n biointeractivas y selectivas para que simultáneamente mejoren la función ósea y ... -
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 ... -
Early Paleozoic construction of southwest Gondwana: evidence from detrital zircons in the Sierras Pampeanas
(2014)Basement exposures in the Sierras Pampeanas at 26º–33ºS give a unique opportunity to compare paleo-sediment sources along a significant stretch of the Andean foreland. To this end we have studied a large number of ... -
Effects of central administration of Coriandrum sativum essential oil on anxiety-like behavior in chicks
(2014)Coriandrum sativum ("cilantro") is an herb with culinary use. Coriandrum essential oil (CEO) is an aromatic complex mixture of volatile terpenes with antibacterial, antifungal, antioxidant activity and when it is ... -
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. ... -
Fast carbon turnover after logging in the Semi-Arid Chaco forest (Argentina)
(2014)Although the effect of forest logging on soil organic C (SOC) has been studied across different ecosystems, there is no consensus on the general resulting pattern, showing increases, decreases or not net changes in comparison ... -
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 ... -
Large effects of land use conversion on C storage in dry forest ecosystems from Southern South America
(2014)Net CO2 land use change emissions represent one of the main drivers of global climatic change. However, the effect of the accelerated deforestation over plant and soil carbon (C) pools from dry Chaco forests from southern ... -
Neuroadaptive events in the offspring induced by maternal voluntary ingestion of hypertonic sodium solution: brain neurochemical system programming
(2014)Osmoregulatory mechanisms can be vulnerable to electrolyte and/or endocrine environmental changes during the perinatal period, differentially programming the developing offspring and affecting them even in adulthood. The ... -
Overview of weathering in a small monolitholigic drainage basin: La Trucha, Sierra de Comechingones, Córdoba, Argentina
(2014)The term weathering is used in the Earth Sciences to denote the in situ breakdown and alteration of rocks and minerals. In the near surface environment, pressure, temperature and water availability differ significantly ... -
Stress in wild greater rhea populations: effects of agricultural activities on fecal glucocorticoid metabolite levels
(2014)In recent years, wild populations of greater rhea (Rhea americana) have declined drastically, due mainly to the conversion of grassland into cropland as a result of intensive, specialized agricultural practices. In this ... -
The continental assembly of SW Gondwana (Ediacaran to Cambrian): a synthesis
(2014)SW Gondwana resulted from complex interplay between continental amalgamation and dispersal between ~ 650 and 490 Ma. The main cratons involved were Laurentia, Amazonia– MARA (Proterozoic Maz–Arequipa–Rio Apa, Casquet et ... -
The geological setting of Carboniferous magmatism in the proto-Andean margin of Gondwana, Sierra Pampeanas, Argentina
(2014)Our petrogenetic understanding of the Carboniferous granites of the Sierras Pampeanas has improved in recent years, but their geodynamic setting is still not well constrained. Domeier and Torsvik (2014) affirm that there ... -
The hydrochemical and isotopic signature of the Middle Paraná River downflow the confluence of Paraguay and Upper Paraná rivers: surface water mixing or groundwater inflow?
(2014)The Paraná River basin is one of the largest hydrological systems in South America (~2.6 x 106 km 2 ). Most large rivers exhibit transverse and longitudinal inhomogeneities downflow the confluence of tributaries, which ... -
The relationships between pre- to syn-Pampean orogeny metasedimentary rocks in the Eastern sierras Pampeanas (Argentina)
(2014)Two series of pre-to syn-Pampean orogeny metasedimentary rocks can be distinguished in the Sierras Pampeanas on the basis of U-Pb SHRIMP detrital zircon ages. On one hand the Ancaján series consists of meta-siliciclastic ...
