New pterosaur tracks from the Aguada de Tuco tracksite of the Cenomanian Candeleros Formation (Neuquén Basin, Argentina) are reported here. They are preserved in medium grain-sized sandstones from fluvial deposits and a...

El artículo describe una patente sobre la composición de aceite vegetal comestible que presenta una concentración de tocoferoles y fitoesteroles -naturales y genuinos- mayor que la correspondiente a la presente en el ...

El presente artículo busca explorar las relaciones entre catolicismo liberacionista y política en la Argentina. Para ello, en primer lugar se trazan una serie de rasgos comunes a los vínculos entre factor religioso y ...

Eight new copper(II) complexes with halo-aspirinate anions have been synthesized: [Cu 2(Fasp) 4(MeCN) 2]·2MeCN (1), [Cu 2(Clasp) 4(MeCN) 2]·2MeCN (2), [Cu 2(Brasp) 4 (MeCN) 2]·2MeCN (3), {[Cu 2(Fasp) 4(Pyrz)]·2MeCN} ...

En Santiago del Estero, Argentina, existen aproximadamente 7 millones de ha de bosques nativos de las cuales muchas poseen individuos del género Prosopis. Además del uso maderero los algarrobos proveen servicios ecosis...

Este trabajo forma parte de un proyecto de investigación sobre la situación de los afroporteños durante el siglo XVII. Se revisaron primordialmente las Escribanías Antiguas (1584-1756), conservadas en el Archivo Gene...

Ex vivo-generated antigen-loaded dendritic cells (DC) have been shown to be immunogenic in patients with cancer. Loading DC with autologous whole tumor antigens is a strategy to arm DC against tumor without human leukocy...

We describe the functional properties of a nicotinic alpha9/serotonin subtype 3A (5HT3A) chimeric receptor expressed in Xenopus laevis oocytes. The chimera preserved ligand-binding properties of alpha9 and channel proper...

En este trabajo se propone caracterizar, desde la dimensión institucional,los aspectos principales del programa local de políticapública denominado “Plan Integral Santiago Emprende”, implementadoen la provincia de...

This work proposes to improve the tactical decision-making of a supply chain (SC) under an uncertain competition scenario through the use of different optimization criteria, which allows to manage not only the specific o...

The Desert Andes contain >4500 ice masses, but only a handful are currently being monitored. We present the mass changes of the small mountain glacier Agua Negra (1 km2) and of the rest of glaciers in the Jáchal river b...

En este trabajo se presenta una evaluación preliminar, mediante simulación electrónica, de una nueva maniobra de reducción de precarga por estimulación eléctrica programada con miras a su uso en un monitor cardíac...

Abstract. Range spread-F (RSF) and occurrence of "satellite" traces prior to RSF onset were studied at the southern peak of the ionospheric equatorial anomaly (EA). Ionograms recorded in September 2007 at the new ionosph...

Background Studies indicate that antibodies cross-reacting with cardiac β1 adrenergic receptors are likely to play a role in the development of chronic Chagas heart disease (CCHD). In parallel, clinical trials have show...

Fossils collected by Abel Peirano from Catamarca and Tucumán in the late 1930s constituted the basis for the creation of the Colección Paleontología de Vertebrados Lillo (PVL) in Tucumán. The collection was formally ...

La caña de azúcar es uno de los cultivos más importantes a nivel mundial. El uso de biotecnología en este cultivo constituye una herramienta importante para el mejoramiento genético y la propagación. Los Sistemas d...

Supported ruthenium catalysts have been shown to be effective for the dry reforming of methane.Besides, ETS-10 titanosilicate has properties able to disperse Ru species. In this work,  microporous ETS-10 titanosilicate ...

Background: The main purpose of the naphtha reforming process is to obtain high octane naphtha, aromatic compounds and hydrogen. The catalysts are bifunctional in nature, having both acid and metal sites. The metal funct...

The oxidation of diesel soot using K/CeO2 catalysts is studied in this paper. The reaction system involved in the catalytic oxidation of soot is quite complex; therefore, the study of reaction mechanisms is particularly ...

Different basic materials, such as K-L zeolite, K-Al2O3, K-Mg/Al mixed oxide and MgO, were used as supports of Pt-catalysts for the dry reforming of methane (DR) reaction. The effects of the distribution of basic strengt...

The Southern green stinkbug (N. viridula) feeds on developing soybean seeds in spite of their strong defenses against herbivory, making this pest one of the most harmful to soybean crops. To test the hypothesis that midg...

Thirty two samples of natural honey produced in the province of La Pampa (Argentina) were characterised on the basis of their phosphorous, aluminium, iron, calcium, magnesium and sodium contents. Analytical determination...
