(Escuela de Ciencias del Mar, 2014)During April-May 2004 the Cruces River wetland ecosystem, located in Valdivia (40°S), southern Chile, was described as shifting from a clear water regime, dominated by the exotic macrophyte Egeria densa, to turbid waters ...
-
(Wiley-Liss Inc., 2014)The nucleus geniculatus lateralis pars ventralis (GLv) is a prominent retinal target in all amniotes. In birds, it is in receipt of a dense and topographically organized retinal projection. The GLv is also the target of ...
-
(Chinese Academy of Sciences, 2014)Due to the higher energy requirements of birds during winter, it is predicted that the activities of metabolic enzymes (e.g., citrate synthase, CS and cytochrome C oxidase, COX) should increase in tandem with increases in ...
-
(Elsevier, 2014)Mitochondrial light strand DNA replication is initiated at light strand replication origins (OLs), short stem-loop hairpins formed by the heavy strand DNA. OL-like secondary structures are also formed by heavy strand DNA ...
-
(2014)Two new diterpenes,2-acetoxy-13-hydroxy-mulin-11-ene and 2-acetoxy-mulin-11, 13-diene,have been isolated from the aerial parts of Azorella spinosa and their structures determined by spectroscopic and conventional chemical ...
-
(Elsevier, 2014)This study compares the bony ear morphology of freshwater and marine odontocetes (toothed whales). Odontocetes are unique among marine mammals in two important respects: 1) they use echolocation; 2) at least three lineages ...
-
(Elsevier B.V., 2014)The preparation of an ITO (Indium Tin Oxide) modified electrode with a mixed valence CoIII/FeII complex is described. The ITO electrode was initially modified with Au nanoparticles by dip coating in order to obtain and ...
-
(2014)Astrocytes in the normal brain possess a stellate shape reflecting their non-migratory properties. Alternatively, in neurodegenerative diseases or after injury, astrocytes become "reactive" in a process known as astrocytosis ...
-
(Sociedad Chilena de Quimica, 2013)The solid solutions Cu2Fe1-XCoXSnS 4, with stannite-type structure are stable up to about 800C. The electrical properties of the Cu2Fe1-XCo XSnS4 ceramic were investigated by complex impedance. The real and imaginary ...
-
(Academic Press, 2014)The taxonomic status of turtle specimens from the Upper Cretaceous (upper Maastrichtian) Quiriquina Formation of Chile is unresolved. The previously described specimens were considered either stem-cheloniid sea turtles or ...
-
(Royal Society of Chemistry, 2014)The ambiguity of the local hardness is resolved by using information theory to select definitions of the local hardness that are as close as possible to a well-defined approximate formula for the local hardness. A condensed ...
-
(Bentham Science Publishers B.V., 2015)© 2015, Bentham Science Publishers.Phytochemical investigation of Azorella madreporica led to the isolation of four known compounds and an unknown chalcone. The structure of the new compound was identified by spectroscopy, ...
-
(2014)Despite their potential biotechnological applications, cold-active xylanolytic enzymes have been poorly studied. In this work, 38 fungi isolated from marine sponges collected in King George Island, Antarctica, were screened ...
-
(2013)A study to evaluate the effect of a three-year rotation with cover crops for the management of plant-parasitic nematodes (PPNs) was performed in two vineyards producing table grapes (Vitis vinifera L.) in a semiarid region ...
-
(Wiley-Liss Inc., 2013)Ethnic and cultural diversity is an increasing reality in the US workplace. The current study highlights the importance of acknowledging the culturally heterogeneous nature of ethnic groups, and the need to focus on social ...
-
(Blackwell Publishing, 2014)Araucaria araucana (Araucaria) is a long-lived conifer growing along a sharp west-east biophysical gradient in the Patagonian Andes. The patterns and climate drivers of Araucaria growth have typically been documented on ...
-
(Oxford University Press, 2012)© The Authors 2012. Background and aims On the basis of morphological evidence, the species involved in South American Pacific coast harmful algal blooms (HABs) has been traditionally recognized as Alexandrium catenella ...
-
(Springer Science and Business Media Netherlands, 2014)The Valparaiso Region is characterized by the presence of air sheds that modulate the general atmospheric circulation with local winds. The ozone concentration in the region increases from the west coast toward the mountainous ...
-
(Society for Neuroscience, 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)The transition from elastic to plastic behaviour in single crystal copper nanowires under uniaxial tensile stress at different concentrations of silver (0.0-0.5 at.% Ag) and at different temperatures (0.1, 100, and 300 K) ...
