Las clasificaciones geomecánicas son muy empleadas en mecánica de rocas para la caracterización de macizos rocosos. Entre las existentes para taludes, el SMR es una de las más empleadas. En el presente artículo se proponen una serie de funciones continuas…

A linearization method of the nonlinear differential equation for conservative nonlinear oscillators is analyzed and discussed. This scheme is based on the Chebyshev series expansion of the restoring force which allows us to obtain a frequency-amplitude relation which is valid…

Open societies are situated in dynamic environments and are formed by heterogeneous autonomous agents. In order to ensure social order, norms have been employed as coordination mechanisms. However, the dynamical features of open systems may cause that norms loose their…

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…

Obtaining holographic volume gratings with high diffraction efficiencies that can be used under white light has been a serious problem for the polyvinyl alcohol-acrylamide-based photopolymers developed by other researchers. In this paper we propose to eliminate the residual monomer in…

New legislation in the Valencian Community (Decree 36/2002, 5th of March) has allowed the expansion of the existent marinas in this region of the SE of Spain, affecting in a significant way the Alicante province that possesses over thirty nautical…

3,3'-Bis(dialkylaminomethyl)-1,1'-binaphth-2-ols (Binolams) have emerged during the last five years as very efficient chiral ligands in many enantioselective processes. Enantiomerically pure Binolams are easily accessible by means of a variety of methods, the most widely used being the so-called chiral Binol…

The examination of the possible direct link between environmental protection and firm performance in the literature has generally produced mixed results. The present paper contributes to the literature by using the resource-based view as a mediating process in this relationship.…

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…

The idea that technology can transfer a person to a different environment without any physical movement and create the illusion of interaction with the artificial environment is not new. Scientists and engineers have been dedicating their efforts to its progressive…
