(ACS publications, 2014)Gold and silver complexes containing the monophosphane 1-PPh2-2-Me-l,2-C2B10H10 with different coordination numbers (2, 3) have been synthesized: [M(7,8-(PPh2)2-C2B9H10)(1-PPh2-2-Me- C2B10H10)] (M = Ag, Au) and ...
-
(Springer, 2014)BACKGROUND: Frugivorous birds are phenologically linked to the fruits that they eat. When there is less fruit in seasonal environments, frugivorous birds complement their diet by eating invertebrates. The depth of the ...
-
(Wiley, 2014)New solid solutions Cu2MnxFe1 xSnS4 were prepared by direct combination of the corresponding elements at 850 8C. The crystal structure of Cu2Mn0.4Fe0.6SnS4 was determined by single-crystal X-ray diffraction. This phase ...

(Pontificia Universidad Católica de Valparaíso, 2014)Durante abril-mayo 2004 el ecosistema del humedal del río Cruces, localizado en Valdivia (40ºS), en el sur de Chile, fue descrito como cambiando de un régimen de aguas claras, dominado por la macrófita introducida Egeria ...
-
(2014-02-01)We study the wave¨Cparticle interaction and the evolution of electromagnetic waves propagating through a solarwind- like plasma composed of cold electrons, isotropic protons, and a small portion of drifting anisotropic ...
-
(2014)Birds still share many traits with their dinosaur ancestors, making them the best living group to reconstruct certain aspects of non-avian theropod biology. Bipedal, digitigrade locomotion and parasagittal hindlimb movement ...
-
(2014)To improve the current understanding of the ammonia distribution in the major urban area of Chile, measurements of atmospheric NH3 were collected in Santiago during three sampling periods (25 April to 27 May, 11 to 26 ...
-
(Springer, 2014)A basidiomycetous yeast, strain E2A-C3- II, was isolated from a marine sponge (Hymeniacidon sp.) collected at a depth of 6 m in Fildes Bay, King George Island, Antarctica. The phylogenetic analysis revealed that the ...
-
(European Geosciences Union&the American Geophysical Union, 2014)Abstract. Propagation of large-amplitude waves in plasmas is subject to several sources of nonlinearity due to relativistic effects, either when particle quiver velocities in the wave field are large, or when thermal ...
-
(2014)Growing evidence suggests that the main olfactory epithelium contains a subset of olfactory sensory neurons (OSNs) responding to pheromones. One candidate subpopulation expresses the calcium activated cation channel TRPM5 ...
-
(2014)Divorced individuals face complex situations when they have children with different ex-partners, or even more, when their new partners have children of their own. In such cases, and when kids spend every other weekend ...
-
(The Company of Biologist, 2014)Mammals exposed to low temperatures increase their metabolic rate to maintain constant body temperature and thus compensate for heat loss. This high and costly energetic demand can be mitigated through thermoregulatory ...
-
(Sociedad de Biología de Chile, 2014)Many angiosperms are exclusively dependent on pollinators for its reproduction (Matallana et al. 2010; Arroyo et al. 2006). However, pollinators sometimes could be erratic and variable in relation to the ecological ...
-
(Universidad de Concepción, 2014)Se determinó la composición botánica de la dieta del Cortarramas Phytotoma rutila en el desierto del Monte central, Argentina, mediante análisis microhistológico de las heces. En ambos sexos, la dieta estuvo compuesta por ...
-
(Elsevier, 2014)The long-term trends and spatial variability of PM2.5 and PM10 over the period between 2000 and 2012 in the Santiago Metropolitan Area, Chile are studied. The annual PM10 and PM2.5 mass concentration ranged between 76 ...
-
(Springer, 2014)Understanding the interaction between anthropogenic land use and the rainfall pattern can be crucial to predict changes in total suspended solids (TSS) in streams and rivers. We assessed the effects of land use and ...
-
(Sociedad Chilena de Química, 2014)An ionic exchange high resolution liquid chromatography (IE-HPLC) method for determination of cations and anions in interstitial water of sediments, affluent and effluent of dams is proposed in this paper. Cations: Na+, ...
-
(Elsevier, 2014)Immobilization of rhodamine 6G in calcium alginate microcapsules was achieved using the polyanion bearing negatively charged aromatic groups poly(sodium 4-styrenesulfonate) as complexing agent. The immobilization of the ...
-
(American Geophysical Union, 2014)The study of complexity in two aspects of the magnetic activity in the Sun-Earth system is presented. We compare the temporal evolution of the magnetic fluctuations in the Earth’s magnetosphere and the spatial distribution ...
