Why did I choose to end this book with the Gila River Indian Community’s effort to win back its water? Because it is a parable about how democracy and its courts can not only serve but also be served by the quest for sustainability. The GRIC water settlement brought a long struggle for environmental justice to a triumphant conclusion. Delivering justice meant that a large portion of the region’s available resources would be sequestered from the growth machine. Instead of supplying a new generation of low-density tract housing, the water could now be used to produce healthy, local food for the area population, and, if nonindustrial agriculture prevailed, the result would be a double win for carbon reduction. Surely, this is how a green polity ought to act, redressing the claims of those who have been aggrieved, and doing it in a way that extends long-term benefits for all. If all responses to environmental injustice were able to follow suit, it would be a welcome model for moving forward. Even if the Gila River example is unlikely to be replicated in other places, its guiding spirit is a sound one. What if the key to sustainability lies in innovating healthy pathways out of poverty for populations at risk, rather than marketing green gizmos to those who already have many options to choose from? These are not mutually exclusive options, of course, but the lessons I took away from my research convinced me of the pressing need for clear alternatives to the eco-apartheid syndrome that afflicts Phoenix and so many other cities. Building a low-carbon economy by targeting only the LOHAS demographic (Lifestyles of Health and Sustainability, the upmarket segment of 40 million, or 20 percent of consumers, nationally) will end up doing little more than adding a green gloss to patterns of chronic inequality. Likewise, placing all of our faith in clean-tech fixes will cede too much decision making to a closed circle of experts who, regardless of their technical prowess, will have no power to prevent the uneven application of their solutions.

Recent advances in the nuclear power generation field have pointed out the need for ferritic steels which will maintain properties at high operating temperatures for extended periods of time. Present designs for the Clinch River Breeder Reactor Project (CRBRP) specify the use of low carbon 2 1/4 Cr - 1 Mo steel for the Steam Generation systems. Many materials development programs have concluded the acceptability of this material; however, little industrial data are available on the mechanical properties of full size production components. This paper evaluates two heats of low carbon 2 1/4 Cr-1 Mo steel subjected to various heat treatments.

AbstractA CVD-based low κ film was evaluated for inter-metal dielectric in < 0.18 [.proportional]m generation devices. The film was deposited by conventional rf PECVD method using organosilane compound and oxygen. The measured dielectric constant of the film was 2.7∼2.75. The κ value of the film was stable over several weeks and the moisture absorption was minimal. The chemical composition was in the form of SiOxCyHz, where the carbon content was less than 5 atomic %. Blanket film integration study was conducted to find out the manufacturing compatibility. The largest increase in κ value occurred during etching and ashing steps. However, SIMS compositional analysis revealed that the damage from these steps were limited to within top 300 Å, and the initial low κ value was recovered after the top damaged layer was removed by CMP. The final integrated dielectric constant was less than 3.0. The film density was measured as 1.4, compared to 2.3 g/cm3 of conventional SiO2. The low density of the film resulted from the termination of SiO2 network structures by Si-CH3 and Si-H.

This paper focuses on the analysis of the microstructure and of the texture through the sheet thickness after temper rolling of very thin ferritic steels. The study uses EBSD and X-Ray diffraction. Comparison is made between an interstitial-free (IF) steel and of some industrial low carbon ferritic steels used after ageing. The experimental results are discussed with respect to the anisotropy of the mechanical behaviour after temper rolling during simple shear tests.
