A correlation procedure for the prediction of vapor - liquid equilibrium of acetic acid-isopropanol-water-isopropyl acetate mixtures has been developed. It is based on the NRTL model for predicting liquidactivity coeffic...

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...

Heavy metal soil contamination is one of the most serious environmental problems, considering both their persistence and progressive accumulation which makes possible the transference to other systems, and could potentia...

Steady-state and time-resolved emission spectroscopy (TRES) of the medium-sensitive probes 4-aminophthalimide (4-AP) and 6-propionyl-2-(dimethylamino)naphthalene (Prodan) were performed at 77 and 298 K in vacuum-sealed t...

In coastal areas, microplastics (MPs) can deposit in sediment, allowing it to be ingested by benthic organisms, like mussels, thus creating a possible transfer to humans. The aim of this study is to evaluate MPs pollutio...

The preservation and cementation of sedimentary structures under the influence of  microorganisms in siliciclastic environments have been poorly studied in contrast to carbonatic settings, where they have been extensive...

A source of entangled photons based on well-separated laser pump pulses (PDs) with a duration in the nanosecond range may be useful in many applications. Yet, such a source has intrinsic problems arising from the simulta...

A comprehensive study of the structural, cohesive and electronic properties of several stable, metastable and non-stable intermetallic phases (IPs) of the Ni–In and Ni–Sn systems have been performed by ab initio dens...

Plants have emerged as a valuable source for neuroprotective compounds like flavonoids. These polyphenolic com pounds decrease neurotoxicity and the development of neurodegeneration. Potentiation of α7 nicotinic recepto...

Aim of the study: In this study the anti-inflammatory activity of aqueous, dichloromethane (CH2Cl2) and methanolic (MeOH) extracts and two major compounds isolated from Lithrea molleoides (Vell.) Engl. (Anacardiaceae) we...

I develop a strategy for representing epistemic states and epistemic changes that seeks to be sensitive to the difference between voluntary and involuntary aspects of our epistemic life, as well as to the role of pragmat...

Borges and Xul Solar were interested in the Holy Scriptures, in Kabbalah, Sufism, Brahamanism, Buddhism and in the cosmological, philosophical and ethical approaches of other thinkers, as Swedenborg and Blake. Borges oft...

The free-living nematode Caenorhabditis elegans has emerged as a powerful model for the study of the nervous system and human diseases and as a model for antiparasitic drug discovery. This nematode has also shown promise...

Abstract Cardiac tissue from autoimmune myocarditis mice was studied to evaluate the expression and biological activity of mRNA encoding H(1) receptor and iNOS. BALB/c inbred mice were immunized with heart protein and s...

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder that affects women in their reproductive age. Recent studies have shown that genes have an important role in the etiology of PCOS. However, th...

Recyclability is the ability of a material to reacquire the same properties it had originally. The aim of this work was to verify the recyclability of three printing and writing papers, from the characteristics of their ...

The Prandtl mixing length model has been used to take into account the turbulent effects in a 30 A high-energy density cutting torch model. In particular, the model requires the introduction of only one adjustable coeffi...

The Neuquén Basin is a stratigraphically- and economically-important Early Cretaceous depocentre located in west-central Argentina. The Early Valanginian to Early Barremian succession (upper Vaca Muerta, Mulichinco and ...

One of the largest silicic igneous provinces of the world, the Chon Aike Volcanic Province, is related to an extensional regime developed in Patagonia in Early to Middle Jurassic times. This work presents new geochemical...

The western coast of South America is one of the most seismogenic zones of the world, due to the subduction of the oceanic Nazca Plate below South America. The spatial distribution of large-magnitude earthquakes or of th...

Nos preguntamos que atributos de la vegetación influencian la selectividad de los ovinos respecto de diferentes unidades de vegetación a lo largo de sus caminos de pastoreo. Obtuvimos 40 000 registros de posiciones de ...

The sector of the Andes studied in this paper (33°30′-33°45′S) presents a key region to study the relationship between tectonic setting and deformation history in a transitional zone between flat (north of 33°S) a...

Amphibians are considered one of the groups most susceptible to chemical contamination, therefore are good bio-indicators of aquatic pollution. Synergistic effects of temperature and pesticides have been found in amphibi...

The hindlimbs of Accipitriformes are vital for capturing prey. Research on hindlimb musculature has primarily focused on species preferring avian and mammalian prey, whereas piscivorous species have received limited atte...
