The structure and composition of benthic communities on hard substrates covered by the nonindigenous bivalve Limnoperna fortunei Dunker, the golden mussel, were quantified in the middle zone of the Río de la Plata Estua...

Cadmium (Cd) is a ubiquitous heavy metal, prevalent as an environmental contaminant. In the general population, exposure to Cd occurs primarily through dietary sources, cigarette smoking, and, to a lesser degree, drinkin...

The aim of this work was to identify closely related rhizobia, used to formulate commercial inoculants, using polymerase chain reaction (PCR). Repetitive extra-genic palindromic (REP) and BOX fingerprints hardly discrimi...

The helminth communities of silverside, Odontesthes bonariensis (Valenciennes, 1835), from two Argentinean lagoons were studied and compared at component community and infracommunity levels. Nine helminth species were fo...

A partir de um conflito entre imigrantes bolivianos em Buenos Aires em torno do “trabalho escravo” nas oficinas de costura da cidade, o artigo trata da relação entre direitos (“ocidentais”) e formas culturais a...

Background: Growth and maintenance of hydatid cysts produced by Echinococcus granulosus have a high requirement for host lipids for biosynthetic processes, membrane building and possibly cellular and developmental signal...

El movimiento sistémico del glifosato está determinado por el transporte de fotoasimilados. A su vez, la capacidad de un destino de consumir los asimilados está condicionada por su actividad metabólica. Pese a su imp...

Los Notoungulata son un grupo de mamíferos fósiles ampliamente diversos y sin representantes vivientes. Prácticamente no se disponen de estimaciones de la masa corporal para la mayoría de los géneros incluidos en es...

Ipomoea carnea subsp. fistulosa, aguapei or mandiyura, is responsible for lysosomal storage in goats. The shrub contains several alkaloids, mainly swansonine which inhibits lysosomal α-mannosidase and Golgi mannosidase ...

Entre as espécies de roedores já estudadas podemos destacar a grande variação na morfologia do aparelho reprodutor masculino. Assim, considerando a importância ecológica dos roedores, e a grande representatividade ...

Purísima-Rumicruz district consists of several polymetallic veins, rich in copper and lead. The veins have a breccia texture and are located in shear bands, with locally high concentrations of sulfides in a carbonatic g...

A nivel internacional, las regiones costeras son zonas de vital relevancia tanto por la población que albergan como por las actividades económicas que en ellas se desarrollan. Los acuíferos costeros tienen ciertas car...

The aim was to evaluate for 75 days the impact on production of the remaining burden of ivermectin (IVM)-resistant parasites in naturally infected feedlot calves. The herds came from tick-infested areas of cattle breedin...

The composition and distribution of the glycoconjugates (GCs) secreted by the epithelium of ovarian lamellae with reference to the reproductive biology of Genypterus blacodes (Schneider, 1801) through lectin hi stochemis...

A new species of Eupalaestrus Pocock, 1901 from northern Argentina is described and illustrated. Males and females of Eupalaestrus larae sp. nov. differ from those all other species of the genus by the color with distinc...

Carrier phase estimation in real-time Global Navigation Satellite System (GNSS) receivers is usually performed by tracking loops due to their very low computational complexity. We show that a careful design of these loop...

Entropy is a powerful tool for the analysis of time series, as it allows describing the probability distributions of the possible state of a system, and therefore the information encoded in it. Nevertheless, important in...

The aim of this study was to estimate the diagnostic value of renal cortex copper (Cu) concentration in clinical cases of acute copper poisoning (ACP). A total of 97 calves that died due to subcutaneous copper administra...

We revisit the Frieden-Hawkins' Fisher order measure with a consideration of temperature effects. To this end, we appeal to the semiclassical approach. The order-measure's appropriateness is validated in the semiclassica...

Ecohydrology is a relatively new and rapidly growing subject area in the hydrology curriculum. It is a trans-disciplinary science derived from the larger earth systems science movement and examining mutual interactions o...

En este libro, se analizan a nivel molecular dos especies que habitan el Archipiélago de Tierra del Fuego (ATDF): una especie endémica (Ctenomys magellanicus) y una invasora (Castor canadensis). Ctenomys magellanicus s...

Concerns about the sustainability of large-scale, direct-drilled RR-soybeans (Glycine max), and RR-maize (Zea mays) under monoculture in central Argentina are growing steadily. An experiment was conducted during three co...
