Nos últimos anos, parte da academia norte-americana mobilizou-se em torno de um grande debate sobre ´antropologia e espionagem´. As acusações feitas sobre alguns colegas eram motivadas pela preocupação sobre o uso...

Precipitation information is critical for understanding the hydrological equilibrium on a global scale. Rain, with other conditions, represents a factor of interest for agricultural production. Therefore, the need of car...

IntroductionEpidermolysis bullosa (EB) is a rare genetic disease with skin and mucosal fragility. Severe cases present major physical and psychological compromise, contributing to comorbidities and reducing oral health-r...

The aim of this work was to study the oxidative stress effects and histological alterations caused by dietary copper on the filter-feeding freshwater mussel Diplodon chilensis. Bivalves were fed during 6 weeks with the g...

Este artículo presenta tres perspectivas analíticas sobre la relación entre computación ubicua (ubicomp) y diversas dimensiones sociales y culturales. Para ello, se reconstruyen las últimas tres décadas de producci...

We demonstrate a grazing-incidence X-ray platform that simultaneously records time-resolved grazing-incidence small-angle X-ray scattering (GISAXS) and grazing-incidence X-ray diffraction (GID) from a femtosecond-laser-i...

Bacillus sp. AR03 have been described as an important producer of carbohydrate-active enzymes (CAZymes) when growing in a peptone-based medium supplemented with simple sugars and/or carboxymethyl cellulose (CMC) as carbo...

Ferrochelatases catalyze the insertion of ferrous iron into the porphyrin during the heme b biosynthesis pathway, which is fundamental for both prokaryotes and eukaryotes. Interestingly, in the active site of ferrochelat...

Un interrogante ha atravesado la historiografía sobre las independencias hispanoamericanas: ¿Se trató de una revolución? Esta pregunta tiene como telón de fondo la cuestión, para nada zanjada, sobre las continuidad...

Abstract Small mammals play an essential role in the transmission and maintenance cycles of Borrelia spirochetes. In Chile, recent studies have characterized novel Borrelia genotypes in ticks collected from small mammals...

We construct compact Salem sets in R/Z of any dimension (including 1), which do not contain any arithmetic progressions of length 3. Moreover, the sets can be taken to be Ahlfors regular if the dimension is less than 1, ...

We show that in ℝd there are purely unrectifiable sets of Hausdorff (and even box counting) dimension d - 1 which are not tube null, settling a question of Carbery, Soria and Vargas, and improving a number of results b...

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 ...

Potentiometric studies of sulfathiazole (HST) in the presence and absence of cobalt(II) were performed. Equilibrium constants for the formation of the detected species, [Co(ST)]+ and [Co(ST)(OH)], are reported. UV-Vis sp...

In Argentina, the organization of waste picker cooperatives has enabled these organizations to impose their approach and point of view in the system of waste management derived from the Integrated Solid Waste Management ...

The authors analyzed the effects of chronic exposure of Argentine air crew members to low doses of ionizing radiations. Genetic damage induced by either low doses or low rates of ionizing radiation was higher than expect...

El artículo se concentra en el estudio de los procesos de constitución del sujeto moderno a partir de la experiencia social y subjetiva del tiempo. Con el objetivo de elaborar un marco conceptual que permita dar cuenta...
