Bleached holograms are one of the most interesting techniques used to produce phase holograms of high quality on photographic emulsions. Of particular interest is the method of fixation-free rehalogenating bleaching. In this paper we will study the influence of the…

Photopolymers are studied as holographic recording materials for recording computer-generated phase holograms. The recording was performed using a holographic copying process, in which the master is produced by means of a high resolution graphic device. To our knowledge it is…

We present a systematic algorithm capable of searching for optimal colors for any lightness L* (between 0 and
100), any illuminant (D65, F2, F7, F11, etc.), and any light source reported by CIE. Color solids are graphed in
some color…

This study examines the relevance of environmental management as a source of competitive advantage for hotels. The relationship between the environmental proactivity of hotels located in the province of Alicante (Spain) and their economic performance levels was studied, and three…

El entrenamiento de la fuerza, utilizando resistencias que actúan por medio de la gravedad (pesos libres, máquinas de palanca, etc.) u otras formas (máquinas hidráulicas, gomas, resortes, etc.), es actualmente considerado una actividad esencial para garantizar un adecuado rendimiento físico…

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…

The aim of this paper is to analyse the Spanish verb acostarse, following the theoretical tools established by Geeraerts (1997). From the perspective of Cognitive Semantics, linguistic categories evolve from prototypic to new meanings as a result of metonymic or…

This paper analyzes the efforts made by the Telefonica Group (the main Spanish firm in the telecommunications sector) to evolve from a bureaucratic culture to another oriented towards total quality and the customer. The need for this change came as…

The electroreflectance (ER) technique has been applied to the study of the electrooxidation of some simple amino acids (glycine, serine and alanine) on a Pt(111) surface in acid medium. A different behaviour in the (1:R)(#R:#E) response as a function of

A new technique for analysing the optical quality of the human cornea is presented. Corneal maps are obtained through keratographies and then converted into phase maps. The propagated fields generated from this surface are plotted and studied. It is shown…
