The seed cone Telemachus is known from several Triassic localities in Gondwana. New specimens from two localities in Antarctica provide additional information about the type species, Telemachus elongatus, based on detail...

El interés por el desarrollo de algoritmos para el procesamiento de imágenes médicas orientadas al estudio del funcionamiento del sistema cardiovascular ha crecido ampliamente en los últimos años. En especial, el ul...

In order to characterize the diet of Astropecten brasiliensis and Luidia ludwigi scotti, the stomach content of both starfish species was analyzed. Starfishes were sampled for two years off Puerto Quequén coast in the B...

En este trabajo se analiza la conformación de un paisaje de dominación mediante la georreferenciación de mapas manuscritos y el traslado de la espacialidad colonial hispanocriolla desde el papel al terreno. La zona es...

El presente trabajo se propone argumentar que el proyecto sociopolítico enunciado por Alberdi en Bases y puntos de partida para la organización política de la República Argentina contribuyó a imposibilitar la consti...

Presentamos una síntesis de lo que conocemos hasta el momento sobre las actividades mineras y metalúrgicas prehispánicas desarrolladas en el territorio de la actual provincia de Jujuy (Argentina). Para ello, se analiz...

Analytical solutions based on the pseudo-steady state approximation (PSSA) were derived for the case of controlled dispersed-drug release from erodible and non-erodible planar matrices, through a membrane, and taking int...

This study integrates a novel multi-beam bathymetry and high-resolution sub-bottom seismic database with previous works, to investigate a Late Quaternary Mixed (turbidite-contourite) Depositional System (MDS) related to ...

Hydrogen is widely considered a promising green energy vector. It may be produced by steam reforming of methane which may be obtained from renewable resources such as biogas or biomass gasification. Nickel catalysts supp...

In wastewater treatment, ammonium removal is a key step which can be done biologically. One method is by coupling a partial nitritation with the Anammox process. The partial nitritation goal is to convert half of the amm...

Pellegrinisaurus powelli is a large titanosaurian sauropod from the Upper Cretaceous of northern Patagonia (Río Negro Province, Argentina). The holotype of this species comprises an incomplete femur, four dorsal and 26 ...

Globe artichoke is rich in nutrients and phenolic compounds. However, nearly 85% of its biomass is discarded following harvest. To propose a scalable and economically attractive process for the revalorization of this mat...

Este trabajo se propone estudiar la dramática del discurso verdadero en los desarrollos foucaultianos de los años 1978 a 1984. La hipótesis que busca señalar es que cada capítulo de esta historia admite actos de pro...

Green laser irradiation successfully activated self-healing processes in epoxy-acid networks modified with low amounts of gold nanoparticles (NPs). A bio-based polymer matrix, obtained by crosslinking epoxidized soybean ...

Composites of cobalt ferrite nanoparticles in a polypyrrole (PPy) matrix have been synthesized in acid media and characterized by X‐ray diffraction studies, scanning and transmission electron microscopy observation, th...

Animal promoters initiate transcription either at precise positions (narrow promoters) or dispersed regions (broad promoters), a distinction referred to as promoter shape. Although highly conserved, the functional proper...

En 1915, los jóvenes artistas argentinos Ricardo Güiraldes y Alfredo González Garaño concibieron Caaporá, un proyecto de ballet que nunca llegó a escenificarse. A partir del análisis del manuscrito intentaré pens...

Uno de los pasos más críticos y complejos, en la minería, es seleccionar el método productivo apropiado, basándose en múltiples parámetros. Esto lo vuelve dificultoso y por ello la importancia de desarrollar una h...

We report an EPR study at X- and Q-bands of polycrystalline and single crystal samples of the mixed copper(II) complex with L-glutamic acid (glu) and 1,10-phenantroline (phen), [Cu(glu)(phen)(H2O)]+ NO3 −·2(H2O). The ...

Species richness and faunistic affinities of gammaridean and corophiidean amphipods from southern Tierra del Fuego were studied. The material was collected with dredges and grabs at 7 locations (15 sampling stations) in ...

The measurement of very short neutron bursts, when individual neutrons cannot be counted in the usual manner, is possible with proportional detectors (such as 3He) taking the integration of the total electric charge due ...

The Deseado Massif, which is located in the western part of the Santa Cruz Province, Argentina, contains numerous hot spring deposits related to the final stages of the Bahía Laura Complex. The aim of this study is to a...
