This book was released on 1984 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploitation d'une méthode acoustique d'étude de la physisorption des gaz rares : argon et krypton, à basse température (40-75 K), sur quartz, en mesurant par les variations des fréquences d'un oscillateur mécanique à ondes de Rayleigh (de fréquence de 20 MHz) les courbes de dispersion de vitesse provoquée par le dépôt des gaz rares sur le trajet de l'onde acoustique. L'interprétation des isothermes expérimentaux est basée sur la théorie de Brunauer, Emmet et Teller adaptée à la technique expérimentale

This book was released on 1991 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: La sensibilité de dispositifs à ondes de Rayleigh aux contraintes mécaniques et thermiques dynamiques a été étudiée théoriquement et expérimentalement afin de trouver des coupes insensibles à ces perturbations extérieures. Deux familles de coupes de quartz à simple rotation localisées autour des anglaes PHI=0#O, THETA=10#O, PSI=30#O) ET (PHI=O#O, THETA=45#O, PSI=45#O) ont été trouvées comme étant peu sensibles aux effets statiques avec un bon accord entre les modèles théoriques et les vérifications expérimentales. De récentes manipulations ont permis de mettre en évidence leur faible sensibilité aux perturbations thermiques dynamiques, avec un gain d'un facteur 10 à 20 par rapport à la coupe de référence (ST,X)

This book was released on 2013-06-29 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Institute for Amorphous Studies was founded in 1982 as the international center for the investigation of amorphous mate rials. It has since played an important role in promoting the und er standing of disordered matter in general. An Institute lecture series on "Fundamentals of Amorphous Materials and Devices" was held during 1982-83 with distinguished speakers from universities and industry. These events were free and open to the public ,and were attended by many representatives of the scientific community. The lectures themselves were highly successful inasmuch as they provided not only formal instruction but also an opportunity for vigorous and stimulating debate. That last element could not be captured within the pages of a book I but the lectures concentrated on the latest advances in the field I which is why their essential contents are he re reproduced in collective form. Together they constitute an interdisciplinary status report of the field. The speakers brought many different viewpoints and a variety of back ground experiences io bear on the problems involved I but though language and conventions vary I the essential unity of the concerns is very clear I as indeed are the ultimate benefits of the many-sided approach.

Download or read book Global Warming and Climate Change written by Emma Carlson Berne and published by Referencepoint Press. This book was released on 2008 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the world, the cause and impact of global warming and climate change is being passionately debated. While many claim that a climate crisis is imminent if greenhouse gases are not curbed, others argue that the effects have been overblown. Through objective overviews, primary sources, and full-color illustrations, this title will examine What Is Global Warming and Climate Change? What Are the Consequences of Global Warming? What Are the Controversies Surrounding Global Warming? What Are the Solutions for Global Warming?
