Resumo No presente artigo, discutem-se a trajetória e as contribuições de António Feliciano de Castilho para as letras e as artes na Ilha de São Miguel, nos Açores, no período de 1847 a 1850. Trata-se de um estudo...

The Roca San Miguel (RSM) archaeological site was occupied during Mousterian times. Here we present a geoarchaeological and paleoenvironmental reconstruction of the site. Five stratigraphic units (A to E) formed by diffe...

El texto expone la necesidad de que toda producción epistemológica en educación se vincule a la práctica pedagógica, posicionando en un lugar central la producción de conocimiento originada en la realidad educativa...

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...

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} ...

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...

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...

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 ...

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...

Deactivation and regeneration of Pt/Al2O3 catalysts during the hydrodechlorination of carbon tetrachloride were studied. The effect of reactant partial pressures and temperature on the catalyst deactivation was investiga...

In few groups of parasites have the patterns of distribution been studied using quantitative methods, even though, the study of these organisms indirectly provides information on the biogeographic history of their hosts,...

The catalytic combustion of diesel soot is addressed with flexible and structured “paper catalysts”. Two different series of catalysts were prepared either by drip impregnation or by a spray method to deposit a mixtu...

This work studies the production of high-value compounds by the cross-metathesis of methyl oleate (MO) with ethylene, cinnamonitrile and cinnamaldehyde using the 2nd generation Hoveyda-Grubbs complex (HG) as catalyst, ei...

Pt catalysts were prepared by encapsulating the active metal in the NaA zeolite structure. The catalysts were prepared by hydrothermal synthesis using two heating sources, conventional heating through a thermal bath and ...

Thermal traits knowledge is elemental to forecasting the impacts of environmental change on lizard diversity. Daily and seasonal environmental temperature fluctuations are amplified in desert and semi-desert species. As ...
