The Big Picture: Reflections on Science, Humanity, and a Quickly Changing Planet

Even if he's discussing tips on how to reconcile financial system with ecology, why a hotter global will lead to extra poison ivy, why Britney Spears will get extra hits on Google than international warming does, or why we'd have to commence consuming jellyfish for supper, David Suzuki issues the path we needs to take as a society if we are hoping to satisfy the environmental demanding situations we are facing in our still-young century.

Climate Change and Terrestrial Carbon Sequestration in Central Asia

This publication brings jointly present wisdom of terrestrial C sequestration in significant Asia. the topics taken care of comprise: biophysical environments, water assets, sustainable agriculture, soil degradation, the consequences of irrigation schemes on secondary salinization, soil administration and its dating to carbon dynamics; the connection among wooded area administration and carbon dynamics, fiscal analyses of land use practices, very important methodological concerns bobbing up from using GIS, distant sensing, carbon budgeting and scaling, and a overview of the data gaps in carbon and weather swap.

Bringing the Biosphere Home: Learning to Perceive Global Environmental Change

This ebook indicates the right way to make international environmental difficulties extra tangible, in order that they develop into an essential component of daily information. At its middle is a straightforward assumption: that the way to discover ways to understand the biosphere is to pay shut consciousness to our fast atmosphere.

Outlooks: Readings for Environmental Literacy

An anthology of appoximately forty contemporary environmental articles from present magazines and technology journals. every one article has a precis of rules awarded, and questions on the finish to aid readers concentrate on the details of the dialogue. a good resource of data for readers.

Sample text

At the end of the stirring period, the molten metal inside the crucible was taken outside the furnace and poured inside a metallic mould of size 3 cm diameter and 17 cm height, to be cooled in air, and solidified to cast metallic matrix composite bars. A small amount of all cast bars’ surfaces were machined to remove possible oxide and contamination during the casting process and prepared for testing by cutting each bar into three portion (top, middle, and bottom) to be used for further study, as it will be seen later in the next paragraphs of the present work.

2. The hardness of the produced composites decreases with the addition of graphite, due to the lubricating action of this material, while the addition of SiC increases the hardness, Because of the high hardness of this industrial ceramic material. 3. Both graphite and SiC particles, when added to the considered metallic matrix, will increase the wear resistance of the considered composites. This is due to the formation of a lubricating film between the mating materials’ interfaces, when graphite is added and the resistance to wear property of the hard and abrasive SiC particles.

The figure show the form changes of the contact surface of the rollers during running. 9 Some Simulation Work of the Tribology Group at KTH The wear modelling and simulation activities conducted by our Group began with the simplified simulation of the wear of gear tooth flanks mentioned previously in this paper [10], followed by the introduction of the principle of single-point observation. Then came several other wear simulation efforts, the main focus of which was to overcome some of the difficulties in determining various parameters, such as contact pressure and sliding speed, at each incremental step of the simulation process.
