Resumo Este artigo aborda os projetos de país desenhados por dois autores/atores entre o final do século XIX e as décadas iniciais do século XX: Rui Barbosa, expoente do pensamento liberal; e Alberto Torres, reconhec...

Resumo Este artigo examina a produção intelectual do sociólogo Carlos Alberto de Medina a partir de sua experiência profissional no Serviço Especial de Saúde Pública e no estudo da SAGMACS sobre as favelas carioca...

When studying the effects of nicotin on adrenal secretion it was found that the injection of this drug into the adrenal gland produced a marked increase of the epinephrin secretion. In this paper the effects of several o...

Leaf-cutter ants play a crucial role in agroecosystems, and understanding their behavior is key to developing effective damage control strategies. While several tracking solutions exist for ants in controlled environment...

Urban air pollution is a serious environmental problem in developing countries worldwide, and health is a pressing issue in the megacities in Latin America. Buenos Aires is a megacity with an estimated moderate Air Quali...

In this paper we study the theory of cleft extensions for a weak bialgebra H. Among other results, we determine when two unitary crossed products of an algebra A by H are equivalent and we prove that if H is a weak Hopf ...

Surface texturing consists of introducingwell-defined, intentional cavities on bearing surfaces, either on the housing or on the rotating shaft. Forsuch configurations, it iswell established in the literature that mass-c...

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 ...

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...

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 ...

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...
