(Wiley, 2017)Fragile X-associated disorders are a family of genetic conditions resulting from the partial or complete loss of fragile X mental retardation protein (FMRP). Among these disorders, fragile X syndrome (FXS) is the most ...
-
(2007)Numerical results for the nuclear Fukui function (NFF) based on a nonintegral number of electrons methodology (NIEM) are reported for a series of simple diatomic molecules. A comparison with those obtained from other ...
-
(TAYLOR & FRANCIS LTD, 2010)Impedance spectroscopy and nuclear magnetic resonance (NMR) were used to investigate the mobility of water molecules located in the interlayer space of Hþ – exchanged bentonite clay. The conductivity obtained by ac ...
-
(ELSEVIER, 2006-03-20)In this work, the nuclear reactivity indices of density functional theory have been generalized to the spin polarized case and their relationship to electron spin polarized indices has been established. in particular, the ...
-
(2007)We propose that a specific property of a chemical fragment, its regional electrophilicity, be taken as defining its nucleofugality index nu(PG) in alpha-elimination reactions. We tabulate this quantity for a series of ...
-
(2007)We introduce and test a nucleophilicity index as a new descriptor of chemical reactivity. The index is derived from a perturbation model for the interaction between the nucleophile and a positive test charge. The computational ...
-
(ELSEVIER, 2006-08-31)A recently introduced empirical nucleophilicity index for a series of n- and pi-nucleophiles was evaluated. The index is based on the frontier molecular orbital information of the nucleophile and its electrophilic partner. ...

(Universidad Nacional Autónoma de México, 2017)Callyntra Solier, 1836 es un género endémico de Chile y Argentina que contiene 22 especies descritas. Con base en ejemplares adultos y unhuevo recolectados en la costa de Chile central, se describe C. tortuosa sp. nov. Se ...
-
(Univ Valparaíso, 2015)We report the mass stranding of 46 false killer whales in the Strait of Magellan in February 2013. We present observation-based information about body size, sex, dental formula and necropsies. Sexual dimorphism in body ...
-
(2003)For difference systems, the new concept expo-(h,k) dichotomy is introduced and exhaustively studied for being used in the asymptotic equivalence of null solutions. An application to Poincaré equations is shown.
-
(Blackwell Publishing Ltd, 2015)© 2014 German Botanical Society and The Royal Botanical Society of the Netherlands.The component Allee effect has been defined as 'a positive relationship between any measure of individual fitness and the number or density ...
-
(Wiley-Blackwell, 2015)The component Allee effect has been defined as a positive relationship between any measure of individual fitness and the number or density of conspecifics'. Larger plant populations or large patches have shown a higher ...
-
(1992)We present a variational approach to the Heisenberg antiferromagnetic model for spin 1/2 and anisotropic exchange, with an external longitudinal and transverse magnetic field. In the one-dimensional case, we calculate ...
-
(1982)Using the Green function technique, the authors calculate the transition probability amplitude for one atom interacting with a one-mode electromagnetic field, without assuming the rotating-wave approximation (RWA). The ...
-
(Taylor and Francis, 2016)In this work, the Lieb-Thirring kinetic energy bound is numerically examined for a variety of systems: the hydrogen-like atoms, neutral atoms, isoelectronic series of atomic ions, the Hooke's atom and some small molecules. ...
-
(Wiley, 2021)Environmental conditions experienced by developing animals have an impact on the development and maturity of the immune system. Specifically, the diet experienced during early development influences the maintenance and ...
-
(1989)Cytochrome P450-dependent oxidation of arachidonic acid was studied in liver microsomes from normal fed, protein-energy malnourished, and refed rats. The overall rate of arachidonic acid oxidation was very similar in ...
