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 ... -
Binding kinetics between soluble beta-Gal and anti-beta-Gal immobilized on chemically nanopatterned surfaces with fractal topography
(2014)The present work was aimed at providing experimental support to the correlation between topographic and kinetic dimensions of protein function we described previously. Through electronic and colloidal nanolithographic ... -
Built environment and modal choice; a case study
(2014)Compact, high density and mixed-used urban environments can exert a strong influence on the way people choose to travel. Very few studies, if any, have taken place in the developing world, particularly at the local scale. ... -
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 ... -
Carbonate collapse and the late Paleozoic ice age marine biodiversity crisis
(2020)The late Paleozoic ice age (LPIA) was characterized by persistently low diversity of marine invertebrates following a second-order mass extinction. Here, we used a data set of North American (paleotropical) fossil ... -
Chemical and Sensory Quality Preservation in Coated Almonds with the Addition of Antioxidants
(2015)Almonds provide many benefits such as preventing heart disease due to their high content of oleic fattyacid-rich oil and other important nutrients. However, they are susceptible to oxidation reactions causing rancidity ... -
Chemical composition and antioxidant activity of phenolic extracts from peanut skins obtained by different industrial process
(2014)Peanut skins present phenolic compounds with antioxidant properties which are excellent as a source of natural antioxidants. In food products, the antioxidants have the function ofneutralizedthe action of free radicals ... -
Classication of Agricultural Fields in Satellite Images Using Two-Dimensional Hidden Markov Models
(2013)Image segmentation is a key competence for many real life applications such as precision agriculture. In this work we present an approach to classify agricultural fields in noisy satellite images. We start with the ... -
Complex oscillatory redox dynamics with signaling potential at the edge between normal and pathological mitochondrial function
(2014)The time-keeping properties bestowed by oscillatory behavior on functional rhythms represent an evolutionarily conserved trait in living systems. Mitochondrial networks function as timekeepers maximizing energetic output ... -
Conservation actions in the master rogram in wildlife management, National University of Córdoba, Argentina: achievements and challenge
(2013)Over its twenty years of experience, the Master Program in Wildlife Management has developed different wildlife conservation and management actions through research, education, and outreach programs, and products of students’ ... -
Contrasting effects of fire frequency on plant traits of three dominant perennial herbs from Chaco Serrano
(Wiley Blackwell Publishing, Inc, 2016)Fire frequencies are currently increasing in many regions a cross the world as a result of anthropic activities, affecting ecological processes and plant population dynamics. Fire can generate important changes in soil ... -
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 ... -
Crossing regions for supersonic cones
(2014)The original study of a conical body of circular cross section at zero angle of attack inside a supersonic flow was developed by Taylor & Maccoll 1933, see [1]. After this year a large amount of numerical and perturbation ... -
Data processing intervals through dynamical models applied to the analysis of self-degenerative systems
(2015)A dynamical model was applied to analyze the data from an actual complex dynamical system. Data are processed at computed intervals of time, which were obtained from the analytical model. This process was developed to ... -
Demographic transition in Argentina
(2014)Demographic transition, epidemiological transition, changes in population. And these changes in the living conditions of the population of Argentina in the last hundred years allow us to estimate that a girl born this ... -
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 ... -
Determination of the stress state in the Andean Cordillera Frontal near the border between Argentina and Chile
(2015)The initial state of stress is an important parameter in underground excavations. From its knowledge, it is possible to calculate the stresses induced around the excavation and the necessary support for stabilization. ... -
Detrended fluctuation analysis as a complementary tool to asses Japanese quail locomotor behaviour in welfare related studies
(2013)The work evaluates the organization and complexity of Japanese quail temporal pattern of locomotion in diverse welfare related experimental situations using Detrended Fluctuation Analysis (DFA). DFA provides information ... -
Differential effects of tianeptine on dorsal hippocampal volume in rats subjected to early stress and variable chronic stress during adulthood (#382)
(2014)Neonatal maternal separation induces long-term alterations in the hypothalamicpituitary-adrenal axis and may increase vulnerability to depression when a stressful situation occurs in adulthood. Some studies, have found ...
