(ELSEVIER, 2006-02-15)A linear relationship was found between the singlet-triplet excitation energy and the energy difference presented by the Kohn-Sham frontier molecular orbitals, independently of the used exchange-correlation functional and ...
-
(SPRINGER, 2006-12)The red alga Mazzaella laminarioides is an economically important species with an extended latitudinal distribution along the Chilean coast. Its populations form mid-intertidal stands, several meters wide, and therefore ...
-
(ELSEVIER, 2006-02-09)Petrosal ganglion neurons are depolarized and fire action potentials in response to acetylcholine and nicotine. However, little is known about the subtype(s) of nicotinic acetylcholine receptors involved, although alpha 4 ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-04)The use of acidophilic, chemolithotrophic microorganisms capable of oxidizing iron and sulfur in industrial processes to recover metals from minerals containing copper, gold and uranium is a well established biotechnology ...
-
(ASME-AMER SOC MECHANICAL ENG, 2006-08)Blood flow dynamics under physiologically realistic pulsatile conditions plays an important role in the growth, rupture, and surgical treatment of intracranial aneurysms. The temporal and spatial variations of wall pressure ...
-
(COLD SPRING HARBOR LAB PRESS, 2007-08)FtsZ has two domains, the amino GTPase domain with a Rossmann fold, and the carboxyl domain that resembles the chorismate mutase fold. Bioinformatics analyses suggest that the interdomain interaction is stronger than the ...
-
(SPRINGER, 2006)The magnetosphere is a multi-scale spatio-temporal complex dynamical system. Self-organization is a possible solution to the seemingly contradicting observation of the repeatable and coherent substorm phenomena with ...
-
(SPRINGER, 2006-05)We studied the pollination and reproductive success in continuous and fragmented populations of Lapageria rosea, a self-compatible plant endemic to temperate forests of Chile. Pollinator abundance, visitation rates, flower ...
-
(BLACKWELL, 2006-11)Correlation among phenotypic traits may be explained by correlational selection, the simultaneous selection of more than one trait, or by genetic and/or developmental factors. In Escallonia myrtoidea, a tree with scented ...
-
(JOHN WILEY, 2006-11-05)The phase behavior of blends containing N-alkylitaconamic acid-co-styrene copolymers (NAIA-co-S) with poly(N-vinyl-2-pyrrolidone) (PVY) of two different weight average molecular weights (M-w($) over bar), poly(2-vinylpyridine) ...

Antioxidant activity of coumarins and flavonols from the resinous exudate of Haplopappus multifolius (PERGAMON-ELSEVIER SCIENCE LTD, 2006-05)The antioxidant activity of eight coumarins and two flavonols isolated from Haplopappus multifolius was studied with the DPPH radical method. Results show that a high concentration of phenolic coumarins and the presence ...
-
(SOC BIOLGIA CHILE, 2006)In mammals, neurogenesis continues during adulthood in restricted places of the nervous system, namely the subventricular zone, the dentate gyrus and the olfactory epithelium. A dual role of the second messenger nitric ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-10)Polycrystalline bismuth sample was compressed in a diamond anvil cell and X-ray diffraction patterns from the body centered cubic phase of bismuth (bcc-Bi) recorded in the pressure range 12-222 GPa. The analysis of diffraction ...
-
(ELSEVIER SCIENCE BV, 2004-12)Ciliary neurotrophic factor (CNTF) is a cytokine whose neurotrophic and differentiating effects over cells in the central nervous system (CNS) have been clearly demonstrated. This article summarizes the general characteristics ...
-
Tau protein binds to pericentromeric DNA: a putative role for nuclear tau in nucleolar organization (COMPANY OF BIOLOGISTS LTD, 2006-05-15)The microtubule-associated tau protein participates in the organization and integrity of the neuronal cytoskeleton. A nuclear form of tau has been described in neuronal and non-neuronal cells, which displays a nucleolar ...
-
(ELSEVIER, 2006-09-15)Anisotropic specimens of MoS2 are obtained by pressing the microcrystalline powder into special die. This inelastic compression results in a rearrangement of the disulfide micro platelets observed by atomic force microscopy ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-06-15)It is shown that the intercalation of [Europium(bipyridine)213, into bentonite results in a new nanocomposite which preserves the emission properties of Europium (111). The exchange of sodium by europium in bentonite is ...
-
(ELSEVIER, 2006-08)We investigated the intraspecific variation in basal metabolic rate (BMR) and total evaporative water loss (TEWL) in the omnivorous passerine Zonotrichia capensis from two populations inhabiting regions with different ...
-
Osmoregulation and adaptive radiation in the ovenbird genus Cinclodes (Passeriformes : Furnariidae) (BLACKWELL, 2006-10)1. The genus Cinclodes is unique among passerines because it includes two species that can be considered marine/coastal and also includes several species that inhabit freshwater streams or that shift habitats between ...
-
(SOC BRASILEIRA QUIMICA, 2006-02)A new and two previously known metabolites possessing a polypropionate carbon skeleton have been isolated from the marine gastropod mollusk Siphonaria lessoni, collected at Chilean coasts. Their structures have been ...
