(American Chemical Society, 2010)A theoretical approach based on time-dependent density functional theory (TDDFT) together with a polarizable continuum model for incorporating the bulk effect of the surrounding environment is used to estimate the ...
-
(2010)We explored the response to habitat desiccation in tadpoles of the warty toad Rhinella spinulosa in a manipulative field experiment. We built an artificial pond system with two desiccation levels (high and low) and ...
-
(Sociedade Brasileira de Química, 2010)Foram sintetizados uma série de copolímeros enxertados biodegradáveis pelo enxerto da e-captolactona sobre dextrana de diferentes pesos moleculares. Os polímeros obtidos foram caracterizados por infravermelho com transformada ...
-
(2009-09-14)We study the dynamics of a pair of nonlinear split-ring resonators (a ‘metadimer’) excited by an alternating magnetic field and coupled magnetically. Linear metadimers of this kind have been recently used as the elementary ...
-
(2009-03-12)The gauge covariant magnetic Weyl calculus has been introduced and studied in previous works. We prove criteria in terms of commutators for operators to be magnetic pseudodifferential operators of suitable symbol classes. ...
-
(ELSEVIER, 2010)Exposure and effect assessment of organophosphate (OP) pesticides generally involves the use of cholinesterase (ChE) inhibition. In earthworm, this enzyme activity is often measured in homogenates from the whole organism. ...
-
(Springer-Verlag, 2010)We present herein a model to deal with the chemical reactivity, selectivity and site activation concepts of p electron systems derived by merging the classical Coulson–Longuet-Higgins response function theory based on ...
-
(Springer, 2010)Cannibalism refers to the action of consuming a member of the same species and is common in many taxa. This paper reviews the available literature on cannibalism in cephalopods. All species of the class Cephalopoda are ...
-
(2010)The Density Functional Theory of chemical reactivity has provided and effective way to develop a mathematical framework for many empirical chemical concepts. In this work, the relation of some of the proposed indexes ...
-
(2010)In this work an alternative to the analysis of the Fukui function will be presented and compared with the traditional condensed function. The topological analysis allows us to define basins corresponding to different ...
-
(Hindawi Publishing Corporation, 2010)We study abstract equations of the form λu t u t c2Au t c2μAu t f t , 0 < λ < μ which is motivated by the study of vibrations of flexible structures possessing internal material damping. We introduce the ...

-
(2010)In this report, we explore the matching of structures to functional needs by comparing previously reported data of maximal oxygen consumption and the development of the lung in the leaf-eared mouse Phyllotis darwini in ...
-
(2010-04)Influenza AH1N1 severely affected the population of Chile. It has high transmissibility, which may stress the health system capacity. An adequate prediction of number of cases and frequency of complications is needed. ...
-
(Elsevier, 2010)We herein report an experimental and theoretical study on the acetylation reaction of benzohydrazide derivatives towards p-nitrophenyl acetate (NPA). The kinetic data are consistent with a stepwise mechanism with the ...
-
(Springer, 2010)In this work, the modification of a glassy carbon electrode with tetraruthenated porphyrins electrostatically assembled onto a Nafion film, previously adsorbed on the electrode surface, is reported. This modified electrode ...
-
(2010)In the present study, we compared Trypanosoma cruzi infection in four native mammals from a hyperendemic area of Chagas disease in Chile for two different periods to assess the occurrence of interannual variation (1999– 2000 ...
-
(Birkhäuser/Springer Basel AG, 2010)Classes of indefinite quadratic forms in a genus are in correspondence with the Galois group of an abelian extension called the spinor class field (Estes and Hsia, Japanese J. Math. 16, 341–350 (1990)). Hsia has proved ...
-
(ELSEVIER, 2010)The anthocyanin fractions were extracted from Cabernet Sauvignon red wine, skins of Vitis vinifera grapes and raspberry fruits (Rubus idaeus). In red wine extract, 16 anthocyanins were identified, malvidin-3-Oglucoside being ...
-
(ELSEVIER, 2010)Nicotinic acetylcholine receptors influence striatal dopaminergic activity and its outcome on motor behavior. For these reasons, nicotinic receptors have been considered as therapeutically relevant targets for Parkinson's ...
