(Neotropical Ornithological Society, 2015)The age and sex structures of the Andean Condor are known for some parts of its range while in other such areas data are lacking. The aim of this study was to obtain demographic data from the Andes of central Chile and to ...
-
(Elsevier Ltd, 2017)© 2016 Elsevier LtdThe structural and up-conversion properties of Er3+ doped BaTiO3 phases have been studied. All phases were synthesized using the sol-gel process. X-ray powder diffraction (PXRD), Raman spectra, scanning ...

(1987)The developmental processes related to odontogenesis are similar in all vertebrates and they occur during embryogenesis. The dental papilla can exercises directive morphogenetic role on epithelia of different phylogenetic ...
-
(1988)The reaction field (RF) model of solvent effects, implemented within the SCF‐CNDO/2 scheme of calculation, has been applied to analyze the proton transfer in the NH3…HCOOH system in the presence of several polarizable ...
-
(1989)The influence of electrostatic solvent effects on the barrier for the internal return rearrangement in the allyl–fluoride model system has been analyzed. The solvent was modeled through the self‐consistent reaction field ...

(Elsevier B.V., 2016)© 2016 Elsevier B.V. We present a reconstruction of environmental changes from sediments of high-altitude Laguna Chepical in the subtropical Andes of Central Chile (32°16′S; 70°30′W, 3050 m a.s.l.) for the past 3100 years. ...
-
(1993)At temperatures between 25 and 35°C, 100% of Prosopis chilensis seeds germinated within 24 h. At higher temperatures, the germination rate was reduced; at 50°C, seeds did not germinate. After germination at 25°C, the optimal ...

(Elsevier GmbH, 2015)© 2014 Elsevier GmbH.Retinoic acid (RA), a vitamin A metabolite, has been attributed to relevant functions in adaptive immunity. On T cells, the disruption on RA signaling alters both CD4+ and CD8+ T cells effector function. ...
-
(1991)Electrostatic solvation energies of singly charged monoatomic ions may be predicted from the knowledge of an electrostatic potential buildup from a physically meaningful ionic radius. Since the asymptotic behavior of the ...
-
(1989)Raman and infrared spectra of evaporated uranyl superphthalocyanine (UO2SPc) films are reported. Raman spectra of UO2SPc (formed by five isoindoline subunits) depart from the general spectral trends observed in metallated ...
