La crisis ambiental que enfrentamos actualmente implica una serie de retos frente a la protección del ambiente como un elemento fundamental para garantizar una vida digna y saludable para las generaciones presentes y futuras. Las reflexiones sobre los procesos y estrategias en la gestión ambiental representan un paso importante para asumir nuevas rutas en relación con el trabajo tanto de las autoridades como de los diferentes actores sociales en el cuidado del planeta. Asuntos como la protección de los ecosistemas, la lucha contra el cambio climático o el reconocimiento de nuevos sujetos de derechos se encuentran en el centro de las discusiones ambientales, por lo cual es imprescindible...
Dear Colleagues, Polymer biointerfaces are considered a suitable alternative to the improvement and development of numerous applications. The optimization of polymer surface properties can control several biological processes, such as cell adhesion, proliferation, viability, and enhanced extracellular matrix secretion functions at biointerfaces. This printed Special Issue on Polymer Biointerfaces is focused on fundamental and applied research on polymers and systems with biological origin. Submissions contain both polymer material background and descriptions of interacting biological phenomena or relevance to prospective applications in biomedical, biochemical, biophysical, biotechnological,...

This Yearbook aims to contribute to a greater awareness of the functions and activities of the organs of the Inter-American system for the protection of human rights. The Yearbook is partly published as an English-Spanish bilingual edition. Two volume set.
The sixth and final volume of the journals of don Diego de Vargas.
This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.
