The electrochemical homo-polymerization of o-, m- and p-aminobenzoic acids has been performed on Pt electrodes in perchloric acid aqueous medium by cyclic scanning of the potential. Different limit potentials were employed to obtain thin polymeric films. When the switching potential…

We are going to analyse the main syntactical processes of thematization and postponement in English in four short stories written by four different Hispanic American writers who wrote around the seventies: Rudolfo Anaya's The Force of Luck, Denise Chávez's Evening…

The electrochemical regeneration of an activated carbon, previously saturated with toluene by gas phase adsorption, was studied. Cathodic and anodic regeneration methods were analyzed using a small batch electrochemical cell. In both cases, a stripping efficiency close to 100% was…

This paper addresses the influence of information technology in human resources management (HRM) and specifically on training policy through the experience of a Spanish telecommunications firm, Telefonica. The characteristics of the training model designed by this firm to face new…

The poly(o-aminophenol) (POAP) redox process has been studied in aqueous acid solution using spectroscopic and optic in situ
techniques. The redox transition of the POAP from its completely oxidized state to its completely reduced state occurs through two
consecutive reactions…

Realistic mathematical models are of great importance for studying the optical performance of the human eye. Light propagation algorithms provide robust methods to calculate field distributions inside a homogeneous medium, and thus they can be applied to the study of…

The theory of quality management has been studied from different areas: quality leaders' ideas, empirical research and formal evaluation models. This has helped identify a set of critical factors for a successful implementation, as a way to improve customer satisfaction…

PII, one of the most conserved signal transduction proteins, is believed to be a key player in the coordination of nitrogen assimilation and carbon metabolism in bacteria, archaea, and plants. However, the identity of PII receptors remains elusive, particularly in…

Anoptical method (microscopic holographic interferometry) has been used to visualize concentration changes in the vicinity of the membrane
surface while a polyethylene glycol 2000 (PEG) solution was ultrafiltered with a cellulose acetate membrane. This interferometric technique
is based on the…
