(2012)Paradoxically, in eukaryotic cells, hydrogen peroxide (H2O2) accumulates in response to oxygen deprivation (hypoxia). The source of H2O2 under hypoxia varies according to the species, organs, and tissue. In nonphotosynt ...
-
(Springer, 2012)It has been reported that dormancy-breaking compound hydrogen cyanamide (HC) stimulates the fermentative pathway and inhibits respiration in grapevinebuds, suggesting in this way, that a respiratory stress must be ...
-
(Springer, 2013)Unlike filamentous fungi and bacteria, very little is known about cultivable yeasts associated with marine sponges, especially those from Antarctic seas. During an expedition to King George Island, in the Antarctica, samples ...

(2009)The Chilean jack mackerel Trachurus murphyi, is a pelagic fish from the Carangidae family that is distributed in the South Pacific Ocean. Because this species constitutes an important economic resource across the South ...

Las instituciones religiosas en la transformación normativa contemporánea en la sexualidad en Chile (2008)Este texto analiza la relación entre orientaciones normativas de las instituciones religiosas y las prácticas sexuales de los sujetos, más precisamente los efectos de la adscripción y la observancia en contexto de ...
-
(Springer-Verlag Berlin Heidelberg, 2013)We consider a simplified model of a nonlinear magnetic metamaterial, consisting of a weakly-coupled, periodic split-ring resonator (SRR) array capable of nonlinear capacitive response. We analyze three related problems: ...
-
(Wiley Periodicals, Inc., 2010)Patterns of cytoplasmic movements and organization of transport pathways were examined in live or fixed zygotes and early zebrafish embryos using a variety of techniques. The zygote blastodisc grows by accumulation of ...
-
(Wiley Periodicals, Inc., 2013)A new procedure is described to visualize the spatial pattern of expression of proteins and mRNAs in cryosections or whole-mounted leech, Drosophila, zebrafish, and chick embryos. Our principal contribution is in the use ...

(Sociedad Chilena de Quimica., 2012-10-12)We report the results of a search of formal relationships between accumulation data and molecular structure for some pollutant molecules (polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and polychlorinated ...
-
(Elsevier , Science Ltd., 2008-09-28)Complexes of Europium(III) and Terbium(III) with 2,2-bipyridine and 1,10-phenanthroline were inserted into Na-bentonite by ion exchange reactions at room temperature. The products display interlaminar distances and ...
-
(Sociedad Química Chilena, 2003-10-02)The structure of the 1: 2 adduct of hexamethylenetetramine and thiaurea was reanalyzed reinterpreting X-ray diffractian data and providing additianal IR and NMRspectrascapic features. The praduct is thus described as ...
-
(Trans Tech Publications Ltd., 2007)The intercalation of long-chain primary amines into the laminar matrices of MoS2 or V2O5-gel leads to well ordered, lamellar organic-inorganic nanocomposites. Powder X-ray diffraction analysis, stoichiometry determined ...
-
(American Scientific Publishers, 2007-11-03)The effect of the neutral surfactant dodecylamine and octadecylamine on the synthesis of TiO2-based nanostructures by the treatment of anatase with NaOH under hydrothermal conditions in the temperature range 120–150 C ...
-
(Elsevier B.V., 2006-08-22)This work explores the functionalization of an organic–inorganic MoS2 lamellar compound, prepared by a chemical liquid deposition method (CLD), that has an interlamellar distance of 5.2 nm, using clusters of gold ...
-
(The Electrochemical Society, 2007-02-02)We report the detailed characterization of high quality vanadium oxide VOx nanotubes NTs and highlight the zipping of adjacent vanadate layers in such NTs formed on remarkable nanourchin structures. These nanostructures ...

Electrochemical behavior of lithium intercalated in a molybdenum disulfide-crown ether nanocomposite (2007 Elsevier Ltd., 2007-06-02)A new nanocomposite, obtained from the intercalation of the cyclic ether 12-Crown-4 into MoS2, Li0.32MoS2(12-Crown-4)0.19, is described. The laminar product has an interlaminar distance of 14.4A° . The electrical conductivity ...
-
(Wiley-VCH, 2004-07-13)The electrical conductivities of a series of MoS2-organic layer nanocomposites prepared by the intercalation of donors like poly(ethylene oxide) and secondary amines are compared. Although for intercalated MoS2 species ...
-
(Elsevier , Science Ltd., 2002-05-19)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 ...
