Tesis de Licenciatura El uso discrecional de la asignación de los recursos públicos ha generado recurrentes disputas entre los distintos niveles de gobierno en los regímenes federales, especialmente cuando los distint...

É um trabalho comum às novas nações e estados independentes a construção da tão controversa identidade nacional. A necessidade de se promover a união de uma população diversificada leva a seleção de símbolos...

Cinco espécies de Poaceae (Gymnopogon burchellii, Ichnanthus bambusiflorus, Leersia ligularis, Merostachys neesii e Paspalum falcatum), oficialmente consideradas "presumivelmente extintas" no Estado de São Paulo, foram...

Acute and post-acute neurological symptoms, signs and diagnoses have been documented in an increasing number of patients infected by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), which causes Coronavi...

The Ampullariidae (‘apple snails’) are freshwater caenogastropods of probable Gondwanan origin that are now indigenously distributed in tropical and temperate zones of southern North America, South America, Africa, I...

We revisit, advancing a useful approximation, a recently formulated QFT treatment that successfully overcomes any troubles with infinities for non-renormalizable QFTs [J. Phys. Comm. 2 115029 (2018)]. Such methodology wa...

Autophagy is a well-conserved process of self-digestion of intracellular components. T. cruzi is a protozoan parasite with a complex life-cycle that involves insect vectors and mammalian hosts. Like other eukaryotic orga...

The host cell recognition and removal of invading pathogens are crucial for the control of microbial infections. However, several microorganisms have developed mechanisms that allow them to survive and replicate intracel...

In this work we search for boundedness results for operators related to the semigroup generated by the degenerate Schrödinger operator Lu=−1ωdivA⋅∇u+Vu, where ω is a weight, A is a matrix depending on x and sati...

This paper analyses the climate change projected for the near and distant future in South America using MRI/JMA (Japanese Meteorological Agency) global model simulations with resolutions of 20 and 60 km. Changes in mean ...

In order to overcome the deficiency of the existing double-ring infiltrometer (DRI) for the soils with high permeability, a new DRI is developed. The device is composed of water injection system and water supply system. ...

The effect of partial substitution of Ce by Pr ions in BaCe1−xPrxO3−δ (0 ≤ x ≤ 0.8) perovskite was studied to improve the proton conductor capability, including transport and mechanical properties, thermodynamic...

Nitrogen availability in Buglossoides arvensis mother plants influences seed dormancy level. Abscisic acid (ABA) levels chiefly determine primary dormancy during embryo maturation and its maintenance depends on ABA/gibbe...

Limite. Sinfonia do sentimento é uma análise comparativa entre duas obras que marcam a história do cinema na América Latina. O filme "Limite" de Mário Peixoto (1931) e "Perón Sinfonia del Sentimiento" de Leonardo F...

This paper addresses trajectory tracking problem in mobile robots considering additive uncertainties. The controller design method is based on linear algebra theory. Numerical estimation techniques are used to estimate t...

It has long been thought that exocytosis was driven exclusively by well-studiedfusion proteins. Some decades ago, the role of lipids became evident andescalated interest in the field. Our laboratory chose a particular ce...

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...

In the present work the existente of mass transfer limitations in slurry, photocatalytic reactors is studied. Experimental validation is made in a flat plate reactor that is part of a recycling system. The reactor is des...

Since the adoption of portable devices like smartphones or smartwatches, the usage of applications has rapidly increased for supporting diverse daily activities from connecting with friends to measuring running distance....

Eutrophication is characterized by excessive plant and algal growth due to the increased of organic matter, carbon dioxide and nutrients in water body. Although eutrophication naturally occurs over centuries as lakes age...

Flower morphology, nectary structure, nectar chemical composition, breeding system, floral visitors and pollination were analysed in Croton sarcopetalus, a diclinous-monoecious shrub from Argentina. Male flowers have fiv...

Verlinde has recently conjectured, via a Beckenstein-like thought experiment, that gravitation, instead of being an elementary force, is an emergent entropic one. This rather surprising conjecture was actually proved in ...

Previously published treatment is rather involved. Here we present a useful approximation to the concomitant derivation that yields a simpler way of handling things and still obtains results quite similar to those yielde...

The demographic characteristics of marine zooplankton make it especially suitable for examining the variability of marine ecosystems. The zooplankton annual succession was studied at a permanent coastal station in the Ar...
