La localidad de Nonogasta en la provincia de La Rioja (Argentina) se abastece para agua potable y riego agrícola del caudal erogado por los manantiales de “El bosquecillo”, como manifestación natural de la descarga...

En este artículo propongo un conjunto de indicaciones propedéuticas para el desarrollo de una investigación acerca de los orígenes del spinozismo de Louis Althusser. En primer lugar, presentaré en qué se reconoce e...

Web designers usually ignore how to model real user expectations and goals, mainly due to the large and heterogeneous audience of the Web. This fact leads to websites which are difficult to comprehend by visitors and com...

Dynamic fault trees (DFTs) are widely adopted in industry to assess the dependability of safety-critical equipment. Since many systems are too large to be studied numerically, DFTs dependability is often analysed using M...

El presente artículo analiza la relación bilateral entre Brasil y Argentina a la luz de los vínculos que ambos países viene construyendo con la República Popular de China. Se sostiene que la profundización de las i...

A spraymethod is proposed to improve the catalytic properties of ceramic papers to be used as catalytic lters for removing diesel soot particles. Small particles of Ce and Co oxides, acting as active centers for the comb...

La mayoría de las proyecciones respecto del futuro de América del Sur se hacen basándose en si la capacidad creciente de demanda de China e India se mantendrá o no en el mediano plazo, y de la forma en que los gobier...

At issue here is the distinction between noise and chaos. They are different phenomena but sometimes produce results that resemble each other. From a numerical viewpoint, in particular, subtle differences that exist betw...

Cell proliferation is an important determinant of plant form, but little is known about how developmental programs control cell division. Here, we describe the role of microRNA miR396 in the coordination of cell prolifer...

A new methodology to design discrete-time multiple resonant controllers for single-phase uninterruptible power supply inverters is proposed in this study. This methodology is based on classical linear tools and consists ...

El presente trabajo tiene como objetivo analizar las respuestas de la política exterior brasileña, durante la administración del Presidente «Lula» da Silva (2003-2010), a la interacción de dos nuevos condicionantes...

Fluid transport on confined systems is a subject of theoretical and technological interest. For instance, remarkable high flow rates have been obtained in carbon nanochannels (CNs) which cannot be predicted by standard m...

En el artículo nos ocupamos del complejo vínculo existente entre lo que denominamos el intelectual de la cultura y la sociología en la Argentina. Interesa tal relación en tanto las ideas y las prácticas del intelect...

El trabajo se propone analizar el protagonismo político del sindicalismo y los movimientos sociales en Brasil, Bolivia y Argentina, considerándolos casos testigos del escenario sudamericano en la medida que representan...

The pecan nutshell [Carya illinoinensis (Wangenh) C. Koch] (PNS) is a source of bioactives with important beneficial properties for the human health. PNS represents between 40–50 % of total mass of the nut, resulting ...

Two kinds of functionalized nanostructured hybrid microspheres, based on the bridged silsesquioxane family, were synthesized by employing the sol-gel method via self-assembly of two different organic-inorganic bridged mo...

A magnetic levitation control system is developed in this work. The non-linear system model is linearized around the operating point. Two control loops, an inner current loop and an outer position loop are designed using...

After reductions of fugitive and diffuse emissions by an industrial complex, a follow-up study was performed to determine the time variability of volatile organic compounds (VOCs) and the lifetime cancer risk (LCR). Pass...

The world expansion of trade in manufactured goods has been more dynamic than production over the last 25 years. The greater trade openness was due more to the growth of extra-regional trade than to intra-regional trade....

Four hydrolysates were obtained from bovine hemoglobin concentrate (BHC) and used to fortify extruded maize products. Extrusion was carried out with a Brabender single-screw extruder. Physicochemical properties from extr...

We define a Larotonda space as a quotient space P = UA/UB of the unitary groups of C ∗ -algebras 1 ∈ B ⊂ A with a faithful unital conditional expectation Φ : A → B. In particular, B is complemented in A, a fact ...

Los Xenarthra (Mammalia) constituyen un grupo monofilético, caracterizado por una arquitectura esqueletaria particularmente distinta a la de los demás mamíferos placentarios. Su distribución actual es casi exclusivam...

Silicon dioxide (SiO2), a material known as “silica” presents properties that make it a good candidate as a biomaterial: it has a very labile surface for functionalization, it is easy to synthesize and it is biocompa...

Partiendo de referencias teóricas relativas a la concepción de lo imaginal, es decir, los modos de constitución de los cuerpos y las sexualidades mediante imágenes, el análisis particular se concentrará en la pelí...
