We study the dynamics of coarsening in a cylinder-forming polystyrene-block-poly(ethylene-alt-propylene) block copolymer thin film deposited on a topographically patterned substrate. Thermal annealing leads to highly ord...

We aimed to evaluate the effects of injectable mineral and vitamin supplementation on weaning calves subjected to a low-stress (fence-line) weaning system. Seven-month-old Aberdeen Angus female calves (n = 40, 152 ± 11 ...

El propósito de este artículo consiste en explicar la idea viquiana del futuro del ser humano desde una perspectiva filosófico-política. El artículo comienza con un análisis del significado del concepto de humanida...

The stress-strain of samples deformed until failure and the relaxation response after 50% deformation of the initial height under constant stress were obtained. Uniaxial compression and stressrelaxation tests enabled s...

A five-level cascaded asymmetric multilevel converter is analysed and designed. This topologysynthesises five voltage levels with a reduced number of components when compared to the most common symmetric topologies. It a...

Time-reversal-invariant topological superconducting (TRITOPS) wires are known to host a fractional spin /4 at their ends. We investigate how this fractional spin affects the Josephson current in a TRITOPS-quantum dot-TRI...

According to the standard conception of free will, the decision to choose one among many possible goals can be construed as a free act if and only if the subject has not been moved -or caused- to choose that goal. In thi...

We show that the Hochschild homology of a differential operator kalgebra E = A#f U(g), is the homology of a deformation of the Chevalley-Eilenberg complex of g with coefficients in (M ⊗A^-∗, b∗). Moreover, when A i...

Studies on regional innovation systems and, particularly, on differentiated knowledge bases are still highly concentrated in Europe. This article presents some original methodologies for adapting these approaches to peri...

Two biogeographical units are generally recognized in the present shelf area of Argentina: the Magellanian andArgentinian Provinces. The two provinces differ in their fossil record. The evolution of these provinces has b...

The paper explores the theoretical and conceptual aspects of urban life quality (ULQ) synthesized in a model that includes the physical support of the cities, in our case of intermediate scales. This model considers the ...

Metal–organic frameworks (MOFs) have emerged as promising materials for atmospheric water harvesting (AWH). Large-pore MOFs provide high water capacity, but their significant hysteresis between sorption and desorption ...

The English Resultative Construction (ERC) is a satellite-framed structure with no identical equivalent in Spanish. In a series of studies, we analyzed and compared recognition (acceptability judgment task) and comprehen...

El Pibí Oriental Contopus virens es una especie migratoria con un amplio rango de cría en el este de América del Norte y un área de invernada que abarca mayormente el noroeste de América del Sur, con menor cantidad ...

Cultures of hybridoma cells in bioreactors are commonly used to produce monoclonal antibodies. As an alternative to nonlinear model predictive control, which has recently been applied successfully to optimize the process...

In volleyball games, we define a rally as the succession of events observed since the ball is served until one of the two teams on the court scores the point. In this process, athletes evolve in response to physical and ...

Nuevos derechos ambientales fueron introducidos en Argentina con la reforma constitucional de 1994. El reconocimiento constitucional de los derechos ambientales es un paso fundamental en el avance de la justicia y la ciu...

La angiogénesis es un proceso complejo caracterizado por una cascada de eventos que llevan a la activación, proliferación y migración de células endoteliales y al remodelado y estabilización del tejido vascular. Re...

En el artículo se analiza el papel de la investigación en la consolidación de las innovaciones pedagógicas. Partiendo de su experiencia de treinta años al frente del Instituto Alberto Merani, y de su permanente cont...

Western corn rootworm (Diabrotica virgifera) (WCR) depends on the continuous availability of corn. Broad adoption of annual crop rotation between corn (Zea mays) and nonhost soybean (Glycine max) exploited WCR biology to...

A systematic approach to the synthesis of compliant mechanisms starting from the problem requirements is proposed. The method uses as topological solution space several atlases of compliant mechanisms specialized from ri...

O artigo se propõe a discutir as complexas mediações entre política, memória e escrita da história, tomando como referência o recente livro de Izabel Andrade Marson, Política, história e método em Joaquim Nabuc...

Water repellency related to organic matter (OM) of coatings along the earthworm burrows (EB) walls can facilitate preferential flow due to limiting the water exchange with the soil matrix. The objectives of this work wer...

One of the main figures of merit in laser-ablative propulsion is the specific impulse, Isp, defined as the impulse per unit weight of fuel, and it is related to the exhaust velocity, ve, by the acceleration of gravity, I...
