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...

La trucha arco iris (Oncorhynchus mykiss) es un predador visual que selecciona a sus presas según la talla y el color. Ejerce un efecto negativo en las comunidades y ecosistemas invadidos en las que son introducidas. El...

El objetivo de este artículo es analizar la demanda de tracción de la agricultura extensiva pampeana a partir de considerar las aptitudes de las dos especies utilizadas. El estudio abarcó 96 colonias del departamento ...

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...

Este trabajo incluye cuatro especies ornamentales de Bryophyllum (Crassulaceae): B.daigremontianum (Raym.-Hamet & H.Perrier) A.Berger, B. delagoense (Eckl. & Zeyh.) Schinz, B. fedtschenkoi (Raym.-Hamet & H.Perrier) Lauz....

Tesis de Maestría A partir de los años 1970, las cúpulas de las carteras encargadas de la conducción económica de buena parte de los gobiernos de nuestra de nuestra región pasaron a ser crecientemente controladas p...

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...

Tesis de Maestría La tesis analiza las autopercepciones y representaciones de los estudiantes integrantes de la comunidad paraguaya en la Universidad Nacional de Hurlingham en el período 2016-2019, realizando una contr...

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...

En la actualidad, prevalece la idea de que la historia colonial hispanoamericana y la historia global constituyen áreas de estudio con poca relación, gestadas en circunstancias historiográficas diferentes. La percepci...

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 ...
