Book Description
En la actualidad existe una gran preocupacion por el ahorro energetico para conseguir una menor dependencia de la energia convencional. La integracion de sistemas de energias renovables en la edificacion, es una importante estrategia para soluciones energeticas sostenibles. Esta integracion se encuentra muchas veces limitada en los proyectos arquitectonicos, al darse prioridad a la parte estetica frente a otros elementos como es el clima, la orientacion de la edificacion o el consumo de energia. La integracion de los captadores solares en componentes externos de los edificios contribuye a la reduccion de costes en la implementacion, permitiendo ademas una mayor libertad arquitectonica. En este libro se estudia un nuevo tipo de captador solar termico integrado en sombreadores de edificios. Ademas de calentar agua, controla las ganancias solares sobre las superficies acristaladas donde es instalado. Se modelo, se valido experimentalmente y se evaluo la aplicacion para calentamiento de agua sanitaria, con estudio de la viabilidad economica y ambiental. Este trabajo puede ayudar a ingenieros o arquitectos que deseen implementar colectores solares termicos en sus proyectos."

Book Description
En este trabajo se presenta la comparación de los resultados de un estudio de eficiencia en estado estacionario realizado a dos diferentes tipos de colectores solares térmicos siendo uno de placas planas y otro de tubos de vacío. Los resultados experimentales se reflejan en figuras, las cuales ilustran la eficiencia de ambos colectores solares a un mismo nivel de radiación. Se detallan las expresiones de cálculo de parámetros térmicos como F\U+2019\UL y F\U+2019\(ta), con valores de -7,87 Wm-2C-1 y 68 % para el colector solar plano y para el Heat pipe -3,01 Wm-2C-1 u un 53,1 % respectivamente. Estos parámetros térmicos dan una caracterización del comportamiento de los dos diferentes colectores solares térmicos y son útiles para el diseño y la caracterización de instalaciones solares de calentamiento de agua.

Estudio Cientifico del ano 2016 en eltema Ingenieria - Ingenieria electrica, Universidad Complutense de Madrid (Facultad de Fisicas), Materia: Master en energia, Idioma: Espanol, Resumen: En este trabajo se ha realizado un analisis energetico y economico de la implantacion de sistemas termosolares. Los resultados se han validado con datos reales de Madrid (Espana) y se ha propuesto su aplicacion en Quito (Ecuador). La estructura del articulo es la siguiente. Tras la introduccion con la motivacion y los objetivos, en la seccion 2 se presenta la modelizacion y simulacion de un colector solar plano. La seccion 3 muestra el desarrollo de un modelo de agua caliente sanitaria (ACS) para Madrid, primero con una herramienta comercial que permite dimensionarlo y validarlo, y despues con un desarrollo propio que permite introducir parametros configurables para la optimizacion del fluido. La seccion 4 describe el analisis de los fluidos y mezclas a utilizar para mejorar la eficiencia. En la seccion 5 se discuten los resultados. En la seccion 6 se presenta la propuesta para la implantacion de colectores solares en la region de la Sierra (Ecuador). El articulo termina con las conclusiones. In this paper a solar thermal system has been modeled and simulated in order to be applied to sanitary hot water (ACS). The main goal of this work is to increase the thermal efficiency by a suitable control system of the pump and improving the heat transfer between the absorber plate and the fluid, testing combinations of different mixtures of compounds and percentages of concentration. The model has been validated with real values from Madrid (Spain). On the one hand, the best mixture of fluids of the solar-thermal system has been obtained. Besides, we have performed a cost analysis and prospects of use of the solar collectors in Ecuador to show the feasibility and advantages of this energy system in this Latin-American country. The simulation results of the whole energy system show a w"

Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Book Description
For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.

Book Description
How can the global environment be safeguarded in the absence of a world government? In the vanguard of efforts to address this critical question, Oran R. Young draws on environmental issues to explore the nature of international governance. Young's analysis invokes the distinction between "governance," a social function involving the management of interdependent individuals or groups, and "government," a set of formal organizations that makes and enforces rules.
