There is limited data regarding the effects of melatonin on the
activity of neuronal acetylcholine receptors (nAChRs) themselves. This study
analyzes the effects of low concentrations of melatonin on nicotine-evoked
currents from cerebellar granule neurons (CGNs) in culture. Using
electrophysiological…

Different Pt-based electrocatalysts supported on carbon nanofibers and carbon black (Vulcan XC-72R) have been prepared using a polymermediated synthesis. The electrocatalysts have been characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and cyclic voltammetry. The effect of carbon nanofibers…

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…

A revision of the calpionellid bio-chronostratigraphy in Western Sicily (Italy)
was carried out, in order to update the taxonomy of this group, through the
identification of some genera (Borziella, Longicollaria, Chitinoidella, Dobeniella,
Sturiella, Borzaiella and Praecalpionellites) and species (Remaniella
catalanoi…

Flexible multisensorial systems are a very important issue in the current industry when
disassembling and recycling tasks have to be performed. These tasks can be performed by
a human operator or by a robot system. In the current paper a…

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…

The transitions and reactions involved in the thermal treatment of several commercial azodicarbonamides (ADC) in an inert atmosphere have been studied by dynamic thermogravimetry analysis (TGA), mass spectrometry and Fourier transform infrared (FTIR) spectroscopy. A pseudo-mechanistic model, involving several competitive…

Este trabajo pretende ser una guía de las investigaciones en historia de la química. Consta de dos partes muy relacionadas entre sí. En la primera parte se ha descrito el desarrollo de la historia de la química como área de…

The electronic energy loss of swift H and He ions in gold is studied, paying special attention to the contribution to the projectile energy loss due to the ionization of the target inner-shells. We calculate the stopping power and the…

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…
