    Description: Los suelos urbanos han sido y son motivo de estudio por parte de investigadores que tratan de aportar soluciones y líneas de trabajo para mejorar las formas de vida y la calidad de nuestro entorno. Así este trabajo parte, por un lado, del interés de un grupo de investigación que, desde años, ha puesto su mirada sobre el estado, condiciones funcionales y desarrollo de los suelos urbanos industriales que, hoy en día, se suman al concepto más amplio de AAE (empresariales, logísticas, comerciales o de desarrollo científico, tecnológico, ) y, por otro, del interés de la Administración Pública Provincial, la Diputación de Valencia, que, en este caso, ha apostado por la mejora permanente de las AAE en su marco territorial. Esta obra forma parte de una serie de tres volúmenes, donde el trabajo o se plantea como una colección de documentos con una temática general común, la renovación de las áreas de actividad económica. La lectura de los diferentes trabajos se puede realizar de forma individual, entendiendo cada volumen como un estudio específico de una determinada AAE de un municipio concreto, y también, como un ejemplo representativo de un ámbito urbanístico con unas características territoriales, urbanas, paisajísticas o de infraestructura concretas, que pueden servir como referencia a otros municipios con elementos en un contexto similar

    Description: This chapter deals with magnetic colloids with catalytic properties for the treatment of polluted waters and the efficient production of fuel alternatives. This kind of materials presents great advantages such as high surface/volume ratio, reproducibility, selectivity, ability to be magnetic harvested, functionalizable surfaces (e.g. with tunable pores and selective chelators deposited on them), high efficiencies and reusability. In particular, this chapter will consider the case of magnetic iron oxide colloids, which can be easily synthesized at low cost, are biocompatible and presents a well-developed surface chemistry. The most common techniques for the synthesis and functionalization of these magnetic nanoparticles will be reviewed and summarized. The iron oxide nanoparticles present outstanding properties that can be exploited in different aspect of the wastewater treatment such as heavy metals and organic pollutants removal by ionic exchange or adsorption, and degradation of the contaminants by advanced oxidation processes, among others. In the field of alternative energies, they have also been used as catalysts for biofuels production from oil crops, in Fischer-Tropsch reactions for liquid hydrocarbons and many other processes with potential environmental impact.

    Description: The optimization of both the chemical vapor deposition (CVD) synthesis method to prepare graphene and the Improved Hummers method to prepare graphite oxide is reported. Copper and nickel were used as catalysts in the CVD-graphene synthesis, CH4 and H2being used as precursor gases. Synthesis variables were optimized according to a thickness value, calculated using a homemade Excel-VBA application. In the case of copper, the maximum thickness value was obtained for those samples synthesized at 1050°C, a CH4/H2 flow rate ratio of 0.07 v/v, a total flow of 60 Nml/min, and a time on stream of 10 min. In the case of nickel, a reaction temperature of 980°C, a CH4/H2 flow rate ratio of 0.07 v/v, a total flow of 80 Nml/min, and a time on stream of 1 min were required to obtain a high thickness value. On the other hand, the Improved Hummers method used in the synthesis of graphite oxide was optimized. The resultant product was similar to that reported in literature in terms of quality and characteristics but both time and cost of the synthesis procedure were considerably decreased.

    Description: Ante la nueva situación generada por la Ley de Áreas Industriales de la Comunitat Valenciana, se entiende como un pilar fundamental del desarrollo social el apoyo a la mejora y promoción de las áreas de actividad económica (AAE).Es necesario desarrollar una base documental adecuada que sirva de referencia para el análisis, el diagnóstico y favorezca concretar los proyectos que posibiliten, optimizando los recursos disponibles, la renovación funcional de las AAE.Algo previsible a corto plazo bajo los indicios de recuperación económica,más claros en unos territorios que en otros, y a medio y largo plazo bajo las expectativas que avala la puesta a punto del Corredor Mediterráneo Ferroviario en la provincia de Valencia.Una premisa que multiplicará las inversiones en suelo destinado a actividades económicas siempre que la oferta de suelo esté a la altura de unas determinadas exigencias de funcionalidad y de perfil urbanístico

    Description: The presence of robots in agriculture has grown significantly in recent years, overcoming some of the challenges and complications of this field. This chapter aims to collect a complete and recent state of the art about the application of robots in agriculture. The work addresses this topic from two perspectives. On the one hand, it involves the disciplines that lead the automation of agriculture, such as precision agriculture and greenhouse farming, and collects the proposals for automatizing tasks like planting and harvesting, environmental monitoring and crop inspection and treatment. On the other hand, it compiles and analyses the robots that are proposed to accomplish these tasks: e.g. manipulators, ground vehicles and aerial robots. Additionally, the chapter reports with more detail some practical experiences about the application of robot teams to crop inspection and treatment in outdoor agriculture, as well as to environmental monitoring in greenhouse farming.
