La producción intelectual de la CEPAL en sus 70 años de existencia ha sido vasta en distintos ámbitos del desarrollo. En este libro se analizan y contextualizan los principales hitos e ideas del pensamiento económico de la CEPAL sobre recursos naturales, medio ambiente y sostenibilidad, organizados en las dos grandes etapas que han caracterizado la vida institucional: la estructuralista (1948-1990) y la neoestructuralista (de 1990 en adelante). A partir de una revisión sistemática de la literatura, se destacan ideas como el vínculo entre la especialización productiva en recursos naturales y los términos de intercambio desfavorables, formulada en los años cincuenta; la soberanía sobre los recursos naturales, en los sesenta; la enunciación temprana del principio de responsabilidades comunes pero diferenciadas, en los setenta; los estilos de desarrollo y medio ambiente, en los ochenta; la competitividad espuria, en los noventa, y la gobernanza de los recursos naturales, el estilo de desarrollo sostenible con igualdad y el gran impulso ambiental, en las dos primeras décadas del siglo XXI. El pensamiento neoestructuralista de la CEPAL es dinámico, abierto y se renueva permanentemente sin perder su tradición estructuralista. El libro aporta también elementos conceptuales para formular un neoestructuralismo ecológico.

The United Nations World Water Assessment Programme (WWAP) is hosted and led by UNESCO. WWAP brings together the work of 31 UN-Water Members and 38 Partners to publish The United Nations World Water Development Report, (WWDR) series. The annual World Water Development Reports focus on strategic water issues. UN-Water Members and Partners, all experts in their respective fields, contribute the latest findings on a specific theme. The 2017 edition of the World Water Development Report focuses on 'Wastewater' and seeks to inform decision-makers, inside and outside the water community, about the importance of managing wastewater as an undervalued and sustainable source of water, energy, nutrients and other recoverable by-products, rather than something to be disposed of or a nuisance to be ignored. The report's title - Wastewater: The Untapped Resource - reflects the critical role that wastewater is poised to play in the context of a circular economy, whereby economic development is balanced with the protection of natural resources and environmental sustainability, and where a cleaner and more sustainable economy has a positive effect on the water quality. Improved wastewater management is not only critical to achieving the Sustainable Development Goal on clean water and sanitation (SDG 6), but also to other goals of the 2030 Agenda for Sustainable Development.

The latest edition of this bestselling textbook treats the important properties of three primary types of material--metals, ceramics, polymers--as well as composites. Describes the relationships that exist between the structural elements of these materials and their characteristics. Emphasizes mechanical behavior and failure along with techniques used to improve the mechanical and failure properties in terms of alteration of structural elements. Individual chapters discuss each of the corrosion, electrical, thermal, magnetic, and optical properties plus economic, environmental, and societal issues. Features a design component which includes design examples, case studies, and design type problems and questions.

El problema de las interferencias electromagnéticas en los sistemas electrónicos ha ido adquiriendo importancia conforme la profusión de las aplicaciones de la electrónica ha aumentado la contaminación electromagnética del entrono de trabajo de los circuitos. La situación se ha visto agraviada al crecer la velocidad y la densidad de integración de los circuitos integrados, que los ha hecho mas susceptibles. Todo ingeniero electrónico con funciones de diseño o producción, tarde o temprano se deve afrontar con este problema. El objetivo de este libro es dar los conceptos y la metodología de solución de los problemas de interferencias electromagnéticas en los sistemas electrónicos. Se ofrece una serie de conceptos básicos organizados sistemáticamente. El libro está organizado en cuatro partes que corresponden a: la descripción del problema, sus soluciones, la aplicación general de éstas y una parte de normas y mediciones relativas a las interferncias y la compativilidad. En apéndices, al final, se han agrupado los conceptos generales más teóricos, las definiciones más comunes, las unidades, y un resumen de los métodos generales de reducción de las interferencias electromagnéticas. Esta obra es de interés para todos los ingenieros y profesionales de los sectores eléctrico y electrónico, así como estudiantes de las carreras de ingeniería electrónica (en particular ingenieros superiores e ingenieros técncios de telecomunicación, industriales e informatica. Puede ser útil en los ámbitos eléctrico y electrónico en el diseño, la producción, las instalaciones y la calidad. Índice resumido del libro; Parte I.
