Objetivo/contexto: este artículo analiza el tránsito desde el marxismo al posmarxismo, y de allí a la perspectiva posfundacional en la obra de Ernesto Laclau, a partir de establecer cuatro temas permanentes a lo largo...

Ernesto Laclau criticises Hegelian dialectics for allegedly introducing the logic of necessity into Marxism, which, he argues, hinders the consideration of contingency. This article examines Laclau’s interpretation of ...

A imagem dominante sobre os anos sessenta no Cone Sul faz referência aos processos de insubordinação social desenvolvidos por setores da população rural, trabalhadores urbanos e jovens de ambos os sexos, desencantad...

In this work, shells are mathematically constructed by applying the cut and paste procedure to D-dimensional spherically symmetric geometries. The weak energy condition for the matter on the shells is briefly analyzed. T...

We study circular shells in a (2+1)-dimensional background within the framework of Einstein-Born-Infeld theory. For shells around black holes we analyze the mechanical stability under perturbations preserving the symmetr...

En este trabajo se detallan los procedimientos y resultados de un proyecto de transferencia tecnológica que incluye un curso teórico práctico sobre la construcción de equipos termosolares de bajo costo para calentami...

The number of studies of Little Ice Age (LIA) glacier fluctuations in southern South America has increased in recent years but is largely biased towards sites in the south Patagonian Andes. In this paper we present a det...

Machine-Learned Likelihood (MLL) is a method that, by combining modern machine-learning techniques with likelihood-based inference tests, allows estimating the experimental sensitivity of high-dimensional data sets. Here...

El proceso de la migración española hacia Argentina fue representado en diversas películas. En la medida en que la cinematografía constituyó el principal vehículo audiovisual de construcción y circulación de imag...

Este artículo estudia a la Federación Argentina de Entidades Democráticas Anticomunistas (FAEDA), una de las más importantes organizaciones anticomunistas de Argentina en la década de 1960. FAEDA reaccionó de maner...

In the present work, ovalbumin (OVA) solutions (10 g/L, 50 mM NaCl, pH 7.5) were heat-treated at 75, 80 and 85°C (namely, OVA-75, OVA-80 and OVA-85, respectively), from 0 to 25 min. OVA nanoparticles (OVAn) around 100 n...

Di-Higgs production at the LHC associated with missing transverse energy is explored in the context of simplified models that generically parameterize a large class of models with heavy scalars and dark matter candidates...

La pérdida de gestación es reconocida como una de las principales causas de ineficiencia reproductiva en vacas lecheras. El objetivo de este trabajo fue evaluar los factores de riesgo de la muerte embrionaria tardía (...

The fossil record of New World vultures (Cathartidae) and hawks (Accipitridae) in South America is extensive but still remains patchy, with relatively few records coming from northern South America. The aim of the presen...

Six new uranyl hybrid materials have been synthesized solvothermally utilizing the ligands 2,2′-bipyridine-3,3′-dicarboxylic acid (H2L) and 2,2′:6′,2′′-terpyridine (TPY). The six compounds are classified as e...

Este artículo indaga en la relación entre maternidades, paternidades y el despliegue de actividades fuera del hogar. A partir de microdatos disponibles del último censo nacional de población de la Argentina, se reali...

In many insects, short photoperiods induce females to lay diapausing eggs, which are associated with a reduction in female fecundity, and/or with an increase in their growth rate, allowing for a larger size at adulthood....

Glaciers in the northern Patagonian Andes (35-46°gS) have shown a dramatic decline in area in the last decades. However, little is known about glacier mass balance changes in this region. This study presents a geodetic ...

In Survival Analysis, the focus of interest is a time $T^*$ until the occurrence of some event. A set of explanatory variables (denoted by a vector $Z$) is considered to analyze if there is a relationship between any of ...

Los gobiernos neopopulistas de los países de la región han avanzado en políticas que tienden a combatir las corporaciones mediáticas y democratizar la comunicación. A partir del análisis del caso argentino, este tr...

Slow waves are commonly observed on the entire solar atmosphere. Assuming a thin flux tube approximation, the cut-off periods of slow-mode magneto-acoustic-gravity waves that travel from the photosphere to the corona wer...

We have applied the short-time dynamics method to the gas-liquid transition to detect the supercooled gas instability (gas spinodal) and the superheated liquid instability (liquid spinodal). Using Monte Carlo simulation,...

We study the irreversible growth of magnetic thin films under the influence of spatially periodic fields by means of extensive Monte Carlo simulations. We find first-order pseudo-phase transitions that separate a dynamic...

We study several simplified dark matter (DM) models and their signatures at the LHC using neural networks. We focus on the usual monojet plus missing transverse energy channel, but to train the algorithms we organize the...
