🍃 Impresión OnDemand
La impresión bajo demanda es un modelo de producción en el que los libros se imprimen uno a uno, según se soliciten, evitando el exceso de stock y reduciendo el desperdicio de papel. Esta modalidad no solo cuida el medioambiente, sino que también permite ofrecer una mayor variedad de títulos sin la necesidad de grandes tiradas.
Entre sus principales beneficios se encuentran:
✔ Sostenibilidad: Se imprime solo lo necesario, reduciendo el impacto ambiental.
✔ Disponibilidad de títulos: Permite acceder a libros que de otro modo no estarían en stock.
Debido a este proceso, los libros impresos bajo demanda pueden tener tiempos de entrega mayores en comparación con aquellos que ya cuentan con stock disponible.
Tu información de pago se procesa de forma segura. No almacenamos los datos de tu tarjeta de crédito ni tenemos acceso a tu información de pago.
For Greener Skies
Each new generation of commercial aircraft produces less noise and fewer emissions per passenger-kilometer (or ton-kilometer of cargo) than the previous generation. However, the demand for air transportation services grows so quickly that total aircraft noise and emissions continue to increase. Meanwhile, federal, state, and local noise and air quality standards in the United States and overseas have become more stringent. It is becoming more difficult to reconcile public demand for inexpensive, easily accessible air transportation services with concurrent desires to reduce noise, improve local air quality, and protect the global environment against climate change and depletion of stratospheric ozone. This situation calls for federal leadership and strong action from industry and government. U.S. government, industry, and universities conduct research and develop technology that could help reduce aircraft noise and emissions-but only if the results are used to improve operational systems or standards. For example, the (now terminated) Advanced Subsonic Technology Program of the National Aeronautics and Space Administration (NASA) generally brought new technology only to the point where a system, subsystem model, or prototype was demonstrated or could be validated in a relevant environment. Completing the maturation process-by fielding affordable, proven, commercially available systems for installation on new or modified aircraft-was left to industry and generally took place only if industry had an economic or regulatory incentive to make the necessary investment. In response to this situation, the Federal Aviation Administration, NASA, and the Environmental Protection Agency, asked the Aeronautics and Space Engineering Board of the National Research Council to recommend research strategies and approaches that would further efforts to mitigate the environmental effects (i.e., noise and emissions) of aviation. The statement of task required the Committee on Aeronautics Research and Technology for Environmental Compatibility to assess whether existing research policies and programs are likely to foster the technological improvements needed to ensure that environmental constraints do not become a significant barrier to growth of the aviation sector.
