A study was undertaken to ascertain the analytical capabilities of l-methionine immobilized on controlled pore glass for Sb preconcentration and speciation. A fully automated on-line system, implemented with hydride gene...

Phosphorus (P) is an essential mineral nutrient for plants, playing central roles in development, growth, and environmental responses. In the soil, P is available in the form of inorganic phosphate (Pi), which, once inco...

The Olrog's Gull Larus atlanticus breeds only in Argentina and is currently categorized as Vulnerable. Knowledge of the location of colonies and an updated understanding of human activities that may impact their breeding...

Vegetation cover is an important factor in soil microbial community composition and activity. We compared the effects of dominant plantspecies cover in a semi-arid scrub environment in northern Patagonia. We compared ind...

4-bromo-3,5-di(methoxy)benzoic acid (I) crystallizes in the monoclinic C2/c space group, a = 22.3405 (6) Å, b = 4.85142 (14) Å, c = 18.1583 (5) Å, β = 93.086 (2)°. The crystal structure shows head-to-head dimeric un...

In this work, we propose a novel method for continuous real-time measurement of the dynamics of the nonlinear refractive index n2. This is particularly important for characterizing phenomena or materials (such as biologi...

We report a novel, to the best of our knowledge, all-optical discrete multilevel time-lens (DM-TL) design based on cross-phase modulation (XPM). In this approach, the pump is synthesized such as the quadratic phase modul...

New pterosaur tracks from the Aguada de Tuco tracksite of the Cenomanian Candeleros Formation (Neuquén Basin, Argentina) are reported here. They are preserved in medium grain-sized sandstones from fluvial deposits and a...

The occurrence of abnormalities in amphibians has been reported in many populations, and its increase could be related to environmental pollution and habitat degradation. We evaluated the type and prevalence of abnormali...

Usually, opinion formation models assume that individuals have an opinion about a given topic which can change due to interactions with others. However, individuals can have different opinions on different topics and the...

Multi-walled carbon nanotubes (CNTs), pristine and subjected to treatments, are comparatively characterized from N2 and Kr (77 K) adsorption measurements. The CNTs are lab-synthesized by in situ chemical vapour depositio...

Post-processing evolution of the functional properties of soybean protein concentrate (SPC) films, plasticized with varying levels of glycerol and processed by compression molding, was examined over a period of 90 days. ...

The Neuquén Basin is a stratigraphically- and economically-important Early Cretaceous depocentre located in west-central Argentina. The Early Valanginian to Early Barremian succession (upper Vaca Muerta, Mulichinco and ...

The lowermost part of the Agua de la Mula Member (upper Hauterivian), Agrio Formation, was studied in distal depositional settings at four locations in the central Neuquén Basin. Detailed sedimentological and ichnologic...

The absence of gluten proteins in sorghum allows for the production of baked goods that are suitable for celiacs. Previous studies have shown that the milling process affects the performance of sorghum flour in baked pro...

Xanthomonas axonopodis pv. citri (Xac) is the causative agent of citrus canker. This bacterium develops a characteristic biofilm on both biotic and abiotic surfaces. To evaluate the participation of the single flagellum ...

The Paleozoic evolution of Patagonia was the focus of controversies between its allochthonous or autochthonous origin. The arrival of plate tectonics supported new allochthonous alternatives and from an initial fixist re...

BackgroundTuberculosis (TB) remains one of the world’s deadliest infectious diseases and continues to be hindered by poor public awareness, stigma, and misinformation, all of which can contribute to delayed diagnosis, ...

Monitoring species abundance and distribution is a prerequisite when assessing species status and population viability, a difficult task to achieve for large herbivores at ecologically meaningful scales. Co-occurrence pa...

1.- The Balcarce Formation is characterized by quarzites and undisputable tidal features.2.- Some ichnogenera like Arthrophycus, Cruziana and Herradurichnus remain valid.3.- At the Cabo Corrientes locality tidal bars and...

The Argentine Continental Margin (ACM) comprises one of the largest contourite depositional systems worldwide, with evidences of strong gravitational downslope and alongslope sediment transport processes. Strong bottom c...

Dictyodora is a complex three-dimensional Paleozoic marine ichnogenus that has been studied for more than a century. However, several problems for the diagnostic features as valid ichnotaxobases remain debatable at an ic...
