The geological roots of South America: 4.1 Ga and 3.7 Ga zircon crystals discovered in N.E. Brazil and N.W. Argentina

2015

International audience; We present new LA-ICP-MS in situ geochronological results for seven Eoarchean zircons dated at 3.7 Ga coming from Cretaceous ash layers of NW Argentina and one Hadean single crystal sampled within the São Francisco Craton in NE Brazil. This zircon comprises a zoned magmatic core dated at 4.1 Ga surrounded by a 1.9 Ga overgrowth related to Paleoproterozoic reworking. This Hadean age is consistent with previously published Nd model ages on orthogneisses from the same domain. These two results represent among the oldest geological witnesses discovered to date in South America, which demonstrates the occurrence of a primitive crust. The contrasting age patterns recorded …

New palaeoecological approaches to interpret climatic fluctuations in Holocene sites of the Pampean region of Argentina

2021

The apparently regular and favourable climate that characterizes the Holocene as an interglacial period shows, however, important climatic instability well documented in the Northern Hemisphere. These fluctuations from colder to warmer or wetter to drier affected both biodiversity and human societies in the last 12,000 years, although the impact in Southern America is still poorly known. We are here investigating the biodiversity of small mammal faunas, more sensitive to climatic changes than large mammals, combining taphonomic and palaeoecological data in the Argentine Pampas to better understand the global nature and effect of these Holocene climatic fluctuations. This paper is pioneering…

Contra la patologización intensiva en términos de derechos humanos: Activismo gordo en Argentina

2020

This work addresses the way in which Argentine Fat Activism has developed, in recent years, the demand for depathologization of fatness, taking elements from critical discourses on the health of fat people to frame them in a perspective typical of the Human Rights. First, the contemporary fat body is described in terms of stigma and discrimination, especially in the health field. Then, they refer to a series of critical positions on the pathologization and medicalization of fatness from the biomedical perspective, Fat Studies and Fat Activism. Lastly, a series of interventions that the Argentine activist collective Taller Hacer la Vista Gorda produced between 2017 and 2020 were considered, …

Affective temperaments in general population: A review and combined analysis from national studies

2010

Abstract Background The aim of this study was to investigate the characteristics of affective temperaments in general non-clinical population in different countries Method We performed a detailed search of published studies (one unpublished) investigating affective temperaments in non-clinical populations by administering the Temperament Evaluation of Memphis, Paris and San Diego Auto-questionnaire (TEMPS-A) in its 110-items version. We have included a total of six studies published from different countries (Argentina, Germany, Hungary, Korea, Lebanon, and Portugal) and one unpublished with preliminary data from Spain. We analyzed the combined data from the collected studies. Results We fou…

Uncinaria hamiltoni (Nematoda: Ancylostomatidae) in South American Sea Lions, Otaria flavescens, From Northern Patagonia, Argentina

2004

Thirty-one South American sea lion pups (Otaria flavescens) found dead in Punta León, Argentina, during the summer of 2002, were examined for hookworms (Uncinaria hamiltoni). Parasite parameters were analyzed in 2 locations of the rookery, i.e., a traditional, well-structured breeding area and an expanding area with juveniles and a lax social structure. Prevalence of hookworms was 50% in both localities, and no difference was observed in prevalence between pup sexes (P > 0.05). Hookworms were concentrated in the small intestine. Transmammary transmission is assumed because only adult hookworms were found in the pups. The mean intensity of hookworms per pup was 135; the mean intensity in fem…

Origin of atmospheric aerosols at the Pierre Auger Observatory using studies of air mass trajectories in South America

2014

The Pierre Auger Observatory is making significant contributions towards understanding the nature and origin of ultra-high energy cosmic rays. One of its main challenges is the monitoring of the atmosphere, both in terms of its state variables and its optical properties. The aim of this work is to analyze aerosol optical depth $\tau_{\rm a}(z)$ values measured from 2004 to 2012 at the observatory, which is located in a remote and relatively unstudied area of the Pampa Amarilla, Argentina. The aerosol optical depth is in average quite low - annual mean $\tau_{\rm a}(3.5~{\rm km})\sim 0.04$ - and shows a seasonal trend with a winter minimum - $\tau_{\rm a}(3.5~{\rm km})\sim 0.03$ -, and a sum…

Borges: Libro-Mundo y Espacio-Tiempo

2011

La continua tensione che esiste tra la pulsione decifratrice dell’uomo e l’incomprensibilità delle leggi che regolano l’universo è la base dialettica su cui si costruisce il discorso, dalla dinamica sapienziale, che sta alla base della metafora del Libro-mondo, nella sua più precisa accezione di Liber Naturae. Nel caso di Galileo la metafora del libro mondo serviva ad affermare, con la propria potenza dirompente, il tentativo di codificare una nuova concezione della scienza e della natura. Una nuova visione del mondo si affermava attraverso l’opposizione tra la lettura diretta del libro della natura e quella indiretta rappresentata dai libri di Aristotele. Borges utilizza la stessa metafora…

Crisis y renovación en el cine de animación argentino. el caso de el empleo

2016

Los procesos de crisis modifican el imaginario social e influyen en la creación artística y en los productos culturales. El objetivo de este trabajo es averiguar la incidencia de la crisis Argentina de 2001 en el cine de animación. A partir del análisis audiovisual de la película El empleo (Santiago Grasso, 2008), buscamos qué elementos se problematizan y qué tipo de discurso plantea. Las conclusiones del trabajo pretenden ampliar la cobertura de los estudios académicos centrados en el impacto de la crisis sobre los productos culturales también al ámbito del cine de animación contemporáneo.
