(SOC CHILENA QUIMICA, 2008-03)Pyrolysis of the mixtures: [NP(O2C12H8)] // AuCl(PPh2) system (I) [NP(O2C2H8)(0.8)[NP(OC6H4CH2CN.{Ru})(2)](0.15) NP(OC6H5)1OC(6)H(4)CH(2)CN.[Ru](0.05)](n) // (BuSiMe2Cl)-Bu-1 system (II) and N3P3[NH(CH2)(3)Si(OEt)(3)](6) ...
-
(OXFORD UNIV PRESS, 2008-04)Background and Aims Adaptation to different pollinators is thought to drive divergence in flower colour and morphology, and may lead to interspecific reproductive isolation. Floral diversity was tested for association with ...
-
(Elsevier, 2008-05-20)For the isomerization of HOONO to nitric acid, a spin triplet reactive intermediate (HOONO)-H-3* was identified on a two state reactivity (TSR) potential energy surface. This bi-radical is postulated as one of the possible ...
-
(ELSEVIER SCIENCE BV, 2008-06)Inducible defenses are a form of phenotypic plasticity that potentially modify direct interactions between various members of an ecological community, generating traitmediated indirect effects. In this work, the hypothesis ...
-
(ELSEVIER SCIENCE BV, 2008-04-20)strong indicators of a changing replacement dynamics in the community. Stationary Markov chain models predict that the future tree composition such Maulino forest fragments will differ from that of continuous, intact ...
-
(JOHN WILEY & SONS, 2008-09)The 3-methoxy-4-hydroxybenzoic acid or vanillic acid (VA) is a naturally occurring molecule important in winemaking. The spectral fingerprints of VA observed in the infrared and Raman spectra are assigned to fundamental ...
-
(BLACKWELL, 2008-06)1. It has been proposed that habitats with low productivity, and hence low resource availability, may favour individuals with lower rates of resource use and energy expenditure. In birds, some studies have shown that basal ...
-
(SOC BIOLGIA CHILE, 2008-03)The current geographical distribution of alien species could be informative of processes involved in the biological invasions facilitated by humans. Because environmental and anthropic factors affect the geographic ...
-
(OXFORD UNIV PRESS, 2008-10)Studies of planktonic organisms have shown that various life-history traits, and consequently population growth rate, can be affected by chemical cues released by high densities of conspecifics. In this work we test for ...
-
(ROCKEFELLER UNIV PRESS, 2008-02)The internal vestibule of large-conductance Ca2+ voltage-activated K+ (BK) channels contains a ring of eight negative charges not present in K+ channels of lower conductance (Glu386 and Glu389 in hSlo) that modulates channel ...
-
(BLACKWELL, 2008-09)1. Here, we report morphological and life-historical changes in the cladoceran Daphnia ambigua in response to chemical cues released by the predatory water mite Piona chilensis. Both species are common inhabitants of ...
-
(AMER CHEMICAL SOC, 2008-06-26)In this paper we report the results obtained by an implementation and application of the simulated annealing optimization procedure to the exploration of the conformational space of small neutral and charged lithium clusters ...

Synthesis and pyrolysis of silicon and tin containing poly(2,2 '-dioxy-1,1 '-biphenoxy-phosphazenes) (PERGAMON-ELSEVIER SCIENCE LTD, 2008-03)The polyphosphazene {[NP(O2Cl2H8)](0.5)[NP(OC6H4Br)(2)](0.5)}(n) (1) [(O2C12H8) = 2,2'-dioxy-1,1'-biphenyl] that, as an strictly alternating copolymer, can be considered nearly as the homopolymer [NP(O2C12H8)NP(OC6H4Br)(2)](n), ...
-
(Instituto de Investigaciones Agropecuarias, INIA, 2008-04)Accumulated chilling was estimated by applying three different models to the hourly autumn-winter temperature records from Santiago (33°34 S lat; 625 m.a.s.l.) and Vicuña (30°02´ S lat; 643 m.a.s.l.) for the years 2005 ...
-
(SPRINGER, 2008-06)Hydrogen cyanamide (HC) is widely used to induce the breakage of endodormancy (ED) in grape and other deciduous fruit crop, though its mechanism of action is poorly understood. Applications of HC to grapevine buds ...
-
(IOP PUBLISHING LTD, 2008-04-09)We studied the structural and dynamical properties of amorphous germanium oxide (GeO2) by means of the molecular dynamics technique. The simulations were done in the microcanonical ensemble, with a system at density of ...
-
(Pergamon-Elsevier, 2008-03-15)The global electrophilicity index that incorporates electrostatic and polarizability contributions shows a quantitative correlation with antiviral and cytotoxic activities of electrophilic sugars. The model is applied to ...
-
(ELSEVIER, 2008-03-20)The ecological processes and interactions that involve plants at the seed level may be altered in a fragmented forest, with consequences on plant recruitment and forest structure. We studied seed production, pre-dispersal ...
-
(Elsevier, 2008-10-23)Experimental observations show that for the gas phase isomerization of protonated molecules, a third body can transport a proton from a high-energy site to a lower energy-site of the substrate, thereby catalyzing the ...
-
(AMER SOC MICROBIOLOGY, 2008-12)Fusarium verticillioides (Gibberella fujikuroi mating population A [MP-A]) is a widespread pathogen on maize and is well-known for producing fumonisins, mycotoxins that cause severe disease in animals and humans. The species ...
