(1992)Infrared spectra of solids Cp*Re(CO)2[PO(OMe)2]X, where Cp* = η5-C5Me5 and X = Cl, Br and I, were recorded. An assignment is offered in which the normal modes are described in terms of "local symmetry". This assignment is ...

(Elsevier, 2002)The FT-IR and Raman spectra in the solid state, the reflection-absorption IR spectra (RAIRS) and the surface enhanced IR (SEIR) and surface enhanced Raman spectra (SERS) of the Ni(II) (trans-7,14-dimethyl-5,12,-diphenyl- ...
-
(Texas State University, 2017)We consider vibrations modeled by the standard linear solid model of viscoelasticity with boundary dissipation. We establish the well-posedness and the exponential stability.
-
(Elsevier, 1997)A symmetry adapted formalism to evaluate the vibronic intensities induced by the ungerade vibrational modes in centrosymmetric coordination compounds of the rare earths is put forward and applied to several selected ...
-
(1991)The relative intensities of about 90 of the more prominent vibronic bands in the2Eg →4A2g luminescence spectrum of the MnF2-6 ion in Cs2SiF6 have been measured at 80 K. The reported intensities cover a range of more than ...
-
(1991)A method to estimate the contribution to the vibronic intensity in electronic transitions of inorganic complex ions due to second order terms in the Herzberg-Teller expansion of vibronic wavefunctions is developed and ...
-
(1990)The vibronic intensities of the vibronic origins due to the three odd-parity vibrational modes of the Г8(2T2g) Г8(4A2g) electronic transition of the ReBr2-6 ion are calculated using both crystal-field and ligand-polarization ...
-
(BLACKWELL, 2006-09)Individuals of social and partially social species typically reduce their vigilance activity when foraging in groups. As a result, per capita risk of predation decreases and individuals allocate more time to foraging and ...
-
(Universidad de Chile, 2012)Se estudió la concentración de partículas virales, bacterias y clorofila a total, junto con las variables ambientales temperatura, salinidad, oxígeno disuelto y nutrientes (nitrato y fosfato) en el mar interior de Chiloé ...
-
(BioMed Central Ltd., 2014)© 2014 Díaz et al.; licensee BioMed Central Ltd.Background: Members of the Orthomyxoviridae family, which contains an important fish pathogen called the infectious salmon anemia virus (ISAV), have a genome consisting of ...
-
(Universidad de Chile, 1984)Se mide el efecto que diferentes sales producen en las viscosidades de soluciones que contengan detergentes catiónicos o aniónicos. Se establece una relación empírica entre las viscosidades relativa de las soluciones y la ...
-
(Universidad de Chile, 2015)La microalga Didymosphenia geminata (descrita por Lyngbye en 1819) es una diatomea bentónica de agua dulce, formadora de tallos extracelulares, que empezó a ser foco de investigación luego de que mundialmente se expandiera, ...
-
(Wiley-Blackwell, 2015)Most systematic studies of the avian visual system have focused on Neognathous species, leaving virtually unexplored the Palaeognathae, comprised of the flightless ratites and the South American tinamous. We investigated ...
-
(2007)Cellular glutathione levels may exceed vitamin C levels by 10-fold, generating the question about the real antioxidant role that low intracellular concentrations of vitamin C can play in the presence of a vast molar excess ...
-
(Universidad de Chile, 2013)La via de señalización de Shh regula importantes eventos moleculares en el sistema nervioso central a través de la transcripción de genes efectores. Sin embargo, algunas funciones parecen ser independientes de la ...
-
(Universidad de Chile, 2010)La migración de las crestas neurales es un proceso complejo que involucra la delaminación de estas células desde un tejido epitelial llamado neuroectodermo, y su posterior desplazamiento hacia diferentes partes del embrión ...
-
(Universisdad de Chile, 2008)Las células dendriticas juegan un papel primordial en la polarización Th1Th2 de la respuesta inmune, puesto que estas células son capaces de integrar y decodificar las señales provenientes del patógeno a través de ...
