Renovación de destinos litorales maduros a partir del patrimonio cultural: Plan Costa Blanca Cultura

El destino turístico Costa Blanca se caracteriza por la existencia de una amplia oferta turística y por su situación privilegiada respecto a los mercados potenciales de demanda. En la actualidad, ambas características no son suficientes para garantizar la competitividad de este espacio; en un contexto turístico enormemente dinámico en el que la diversidad de elementos de atracción y la imagen del destino puede incidir en la decisión de viaje de los turistas. Por ello, ante la necesidad de acometer procesos de renovación del destino Costa Blanca que permitan garantizar la competitividad de la actividad en términos territoriales y económicos, se apuesta por el patrimonio cultural como uno de los argumentos que mayores posibilidades puede ofrecer desde el ámbito de la planificación del destino turístico para diseñar y ejecutar actuaciones encaminadas a la renovación del mismo. Así, la presente comunicación se basa en los principales resultados obtenidos en el Plan Costa Blanca Cultura, con el objetivo de analizar el grado de uso turístico del patrimonio cultural de la provincia de Alicante, para a partir de un diagnóstico previo, proponer estrategias y actuaciones encaminadas al diseño y gestión posterior de productos temáticos de naturaleza cultural. La metodología de trabajo se ha basado entre otras acciones, en la participación de los agentes turísticos y sociales, aspecto que ha llevado a la selección de las líneas de trabajo prioritarias basadas en temas que superarían la dicotomía entre litoral e interior otorgando al patrimonio un papel integrador del territorio, y a la propuesta de un modelo de gestión innovador en el destino Costa Blanca.

Plastisol foaming process. Decomposition of the foaming agent, polymer behavior in the corresponding temperature range and resulting foam properties

The decomposition of azodicarbonamide, used as foaming agent in PVC—plasticizer (1/1) plastisols was studied by DSC. Nineteen different plasticizers, all belonging to the ester family, two being polymeric (polyadipates), were compared. The temperature of maximum decomposition rate (in anisothermal regime at 5 K min−1 scanning rate), ranges between 434 and 452 K. The heat of decomposition ranges between 8.7 and 12.5 J g−1. Some trends of variation of these parameters appear significant and are discussed in terms of solvent (matrix) and viscosity effects on the decomposition reactions. The shear modulus at 1 Hz frequency was determined at the temperature of maximum rate of foaming agent decomposition, and differs significantly from a sample to another. The foam density was determined at ambient temperature and the volume fraction of bubbles was used as criterion to judge the efficiency of the foaming process. The results reveal the existence of an optimal shear modulus of the order of 2 kPa that corresponds roughly to plasticizer molar masses of the order of 450 ± 50 g mol−1. Heavier plasticizers, especially polymeric ones are too difficult to deform. Lighter plasticizers such as diethyl phthalate (DEP) deform too easily and presumably facilitate bubble collapse.

Steamboats and pleasure travels: success and failure of the first Spanish initiatives in the mid-nineteenth century

Steam technology revolutionised maritime transport during the nineteenth century. Together with the establishment of the first regular lines, steamers soon led to the commencement of pleasure navigation. The aim of this article is to analyse the impact and scope of this process in Spain, by means of a study of the first experiences in the mid-nineteenth century. In addition to a brief introduction and final conclusions, the paper is structured around four sections. The first contains an appraisal of the situation of passenger transport. Some information is then provided regarding the first cruise in 1854. Next, the essay highlights some of the features of short excursions that were very well received by the public, especially in the island of Majorca. Finally, attention is given to a very special type of travel, the main attraction of which lay in the opportunity to witness an event of a military nature.
