A detailed study about the synthesis, characterization and properties of poly(o-methylaniline)(PoMea)/maghnite nanocomposites
has been performed. Changes in the characteristics of the nanocomposites, depending on the intercalated cation
between the clay layers before the synthesis, have been observed. Intercalated morphology has…

Back in the 1990s Malcolm Coulthard announced the beginnings of an emerging discipline, forensic linguistics, resulting from the interface of language, crime and the law. Today the courts are more than ever calling on language experts to help in certain…

A procedure to determine the best image range of distances that can be obtained from an aphakic eye is presented. Corneal surfaces are calculated from videokeratographic data. Light distributions at different distances inside the eye are calculated with a near-field…

Evaluations are provided of 21 descriptors of Posidonia oceanica meadows along the coast of Valencia, Spain, with a view to using these in implementing the European Water Framework Directive (WFD). The descriptors selected are known to respond to a variety…

¡Quien no aguanta no vale! Dice un viejo principio rarámuri, grupo étnico ubicado en
la Sierra Tarahumara, dentro de la Sierra Madre Occidental del Estado Chihuahua en
México. Inmerso en un entorno ambiental ecológicamente duro para la supervivencia,

The physical and physiological demands of high-level male soccer have been studied extensively, while few studies have investigated the demands placed on females during match-play, however, there is no information available about the heart rate and activity profile of young…

Silver halide sensitized gelatin (SHSG) is an interesting technique for the production of holographic optical elements. It combines the high sensitivity of photographic emulsions with the well-known low scattering and high diffraction efficiency corresponding to dichromated gelatin. In this paper…

The bibliographic impact factor (BIF) of Thomson Scientific is sometimes not a valid scientometric indicator for a number of reasons. One major reason is the strong influence of the number of “source items” or “articles” for each journal that the…

The electrocatalytic oxidation of ferrocene (Fc) at neutral pH in aqueous solution has been studied over thin films of electroactive sulfonated polyaniline (SPAN) by cyclic voltammetry. Strong adsorption of the oxidised species (ferrocenium ion) on the polymer arises as the…

The second-order harmonic balance method is used to construct three approximate frequency-amplitude relations for a conservative nonlinear singular oscillator in which the restoring force is inversely proportional to the dependent variable. Two procedures are used to solve the nonlinear differential…
