Anisakid larvae in the musculature of the Argentinean hake, Merluccius hubbsi
2000
We report the infection levels of third-stage anisakid larva in the muscle of the Argentinean hake, Merluccius hubbsi, in relation to fish size and location in the musculature. The musculature of 42 hake was separated into hypaxial (ventral) and epiaxial (dorsal) parts and surveyed for nematode larvae. Two anisakid species were detected: Anisakis sp. (prevalence, 52.4%; mean +/- SD abundance, 1.2 +/- 1.7) and Pseudoterranova sp. (prevalence, 9.5%; mean +/- SD abundance, 0.2 +/- 0.7). Since the fish were gutted after capture, the occurrence of anisakids in the flesh indicates that the worms had migrated into the muscle before capture. The number of Anisakis sp. in muscle was not correlated w…
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…
The Added-Value of Remotely-Sensed Soil Moisture Data for Agricultural Drought Detection in Argentina
2021
In countries where the economy relies mostly on agricultural-livestock activities, such as Argentina, droughts cause significant economic losses. Currently, the most-used drought indices by the Argentinian National Meteorological and Hydrological Services are based on field precipitation data, such as the standardized precipitation index (SPI) and the standardized precipitation evapotranspiration index (SPEI). In this article, we explored the performance of the satellite-based soil moisture agricultural drought index (SMADI) for agricultural drought detection in Argentina during 2010-2015, and compared it with the one from the standardized soil moisture anomalies (SSMA), SPI and SPEI (at on…
Saccharomyces eubayanusandSaccharomyces uvarumassociated with the fermentation ofAraucaria araucanaseeds in Patagonia
2014
Mudai is a traditional fermented beverage, made from the seeds of the Araucaria araucana tree by Mapuche communities. The main goal of the present study was to identify and characterize the yeast microbiota responsible of Mudai fermentation as well as from A. araucana seeds and bark from different locations in Northern Patagonia. Only Hanseniaspora uvarum and a commercial bakery strain of Saccharomyces cerevisiae were isolated from Mudai and all Saccharomyces isolates recovered from A. araucana seed and bark samples belonged to the cryotolerant species Saccharomyces eubayanus and Saccharomyces uvarum. These two species were already reported in Nothofagus trees from Patagonia; however, this …
Fascioliasis in Llama, Lama glama, in Andean Endemic Areas: Experimental Transmission Capacity by the High Altitude Snail Vector Galba truncatula and…
2021
Simple Summary The infection by the liver fluke Fasciola hepatica in South American camelids, mainly llamas and alpacas, has been the focus of many studies. However, their capacity to participate in the transmission of the disease and their potential reservoir role in human or animal endemic areas have never been studied. Therefore, all development stages of an isolate from Argentine llama of the high Andean plateau have been experimentally investigated, from egg embryogenesis to metacercarial infectivity, by using the vector snail Galba truncatula from the high altitude Bolivian Altiplano human hyperendemic area. Although eggs shed by llamas may successfully develop until the adult stage i…
Constitutional developments in Latin American abortion law.
2016
Abstract For most of the 20th Century, restrictive abortion laws were in place in continental Latin America. In recent years, reforms have caused a liberalizing shift, supported by constitutional decisions of the countries’ high courts. The present article offers an overview of the turn toward more liberal rules and the resolution of abortion disputes by reference to national constitutions. For such purpose, the main legal changes of abortion laws in the last decade are first surveyed. Landmark decisions of the high courts of Argentina, Bolivia, Colombia, and Mexico are then analyzed. It is shown that courts have accepted the need to balance interests and competing rights to ground less res…
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…

Elogio del populismo (en ciertas circunstancias). Notas sobre el kirchnerismo en Argentina
2014
Los trabajos de Ernesto Laclau (2005, 2009) han inspirado una teoría política del populismo que constituye una superación de los enfoques precedentes y que conviene revisar como andamiaje analítico y heurístico. Esta teoría nos ayuda a reconstruir tres dimensiones polémicas que han sido objeto de los estudios sobre la temática. Primero, el populismo asociado a un tipo de discurso. Segundo, como una lógica política que apunta a la producción de una identidad popular (el pueblo) a partir de la interpelación y de la articulación. Tercero, como un proceso político que refiere a la inclusión radical, la transformación del orden social y su relación con la democracia. Como veremos, esta diferenci…
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.
