(1981)Af-methylacetamide and acetamide has been studied. The chemical shifts at infinite dilution show approximately linear relationships with the donor number of the solvent. In strong donor solvents it is possible to observe ...
-
(Pergamon-Elsevier, 2003)Transparent lithium-ion conducting films were prepared by adding lithium perchlorate to a mixture of chitosane (CHI) and poly(aminopropylsiloxane) (pAPS) in a molar ratio 0.6:1 by sol /gel methods. The morphological and ...
-
(American Chemical Society, 2000)Chitosan/poly(aminopropylsiloxane) hybrid films were obtained by blending 3-(aminopropyl)siloxane oligomers (pAPS) with chitosan (CHI). The pAPS oligomers were prepared by the sol-gel method starting from 3-(aminopropy ...
-
(Elsevier, 2013)Sorbitol is converted to fructose in Rosaceae species by SORBITOL DEHYDROGENASE (SDH, EC 1.1.1.14), especially in sink organs. SDH has also been found in non-Rosaceae species and here we show that the protein encoded by ...
-
(2013)Myelin sheaths present two distinct domains: compacted myelin spirals and fl anking non-compacted cytoplasmic channels, where lipid and protein segregation is established by unknown mechanisms. Septins, a conserved family ...
-
(Elsevier, 2013)Three different pollination syndromes (bee, hummingbird and moth-pollination syndromes) have been described for the different species of the genus Schizanthus Ruiz & Pav. (Solanaceae). Two closely related species from a ...
-
(Optical Society of America, 2013-04)On the basis of a rigorous, nonperturbative, purely numerical solution of the corresponding reduced Rayleigh equation for the scattering amplitudes we have studied the scattering of a surface plasmon polariton by a two ...
-
(PLoS ONE, 2013)The Sonic Hedgehog (Shh) pathway is responsible for critical patterning events early in development and for regulating the delicate balance between proliferation and differentiation in the developing and adult vertebrate ...
-
(Springer, 2013)The possibility that social foragers adjust and coordinate their scanning activity when in the presence of close relatives to attain inclusive fitness benefits remains controversial and scarcely examined. To this aim, ...
-
(American Chemical Society, 2013)We herein report on the usefulness of the reactivity indices profiles along a reaction coordinate. The model is tested to fully describe the reaction mechanism of the title reactions. Group nucleophilicity and electrophilicity ...
-
(John Wiley & Sons, 2013)The Raman and surface enhanced Raman scattering (SERS) spectra of a black dyed silk sample (BDS) were registered. The spectral analysis was performed on the basis of Raman and SERS spectral data of isolated samples of ...
-
(Elsevier, 2013)The structural configurations and magnetic properties of zig-zag nanoribbons and nanowires of Fe8−NCoN, for 0≤N≤8, are calculated within the density functional theory. Both, for the zig-zag nanoribbons and the nanowires, ...

(2013)Objetivo. Conocer las percepciones de los tomadores de decisiones respecto de la etapa de implementación de la política de autogestión hospitalaria en dos hospitales de alta complejidad del sur de Chile. Métodos. Se ...
-
(The Fisheries Society of the British Isles, 2013)This study presents phylogenetic molecular data of the Chilean species of Orestias to propose an allopatric divergence hypothesis and phylogeographic evidence that suggests the relevance of abiotic factors in promoting ...
-
(2013)A pesar de que varios estudios han observado que la fragmentación del hábitat facilita la invasión de especies exóticas, trabajos realizados en distintos taxa han observado patrones diferentes. Lamentablemente, el uso de ...
-
(Elsevier, 2013)Recent experiments on shorebirds have demonstrated that maintaining an active osmoregulatory machinery is energetically expensive. This may, in part, explain diet and habitat selection in birds with salt glands. However ...
-
(Elsevier, 2013)The consumption of hallucinogenic substances is a long-standing tradition in the Americas. San Pedro de Atacama (SPA) in Northern Chile is the archaeological zone with the highest incidence of snuffing implements in the ...
-
(Springer, 2013)Using an exponential model for the variation in energy with respect to the number of electrons it is shown that, within the model, the hardness, softness, electrophilicity and other global parameters connected to higher ...
-
(Elsevier, 2013)We explore the nontrivial behavior of a particular city traffic model due to its minimalistic representation of basic city traffic dynamics. The chaotic behavior is studied through the supertrack functions, an approach ...
-
(Elsevier, 2013)Suspended solids play an ecologically important role in glacier-fed fjords, given its dominant effect on their primary production arising from the generation of turbid water plumes by retreating glaciers, which increase ...
