Improved magnesia for thermal control coatings

Formation of radiation-generated color centers using single crystals of magnesium oxide is discussed. Crystal structure of magnesium oxide is described. Chemical processes used to produce magnesium oxide with desired color center kinetics are presented. Proton irradiation of magnesium oxide crystals was conducted to determine lattice defects

Lower Class Mobilization and State Welfare Policy in the Era of Welfare Reform

The 1990s played host to the most significant changes in the American welfare system in the last fifty years— in particular, states were granted much wider latitude in deciding who is eligible to receive welfare. Taking advantage of these changes, we examine the linkage between lower class turnout and state adoption of restrictive welfare eligibility requirements after the passage of the historic welfare reform legislation of 1996. We find that in states where lower class turnout was relatively high, lawmakers were much less likely to pass a range of “get tough” welfare rules. Our findings provide novel support for the importance of electoral mobilization in helping the lower class achieve policies consistent with their interests. However, we also uncover evidence consistent with a “group threat” hypothesis in that states with larger lower class populations tended to adopt more restrictive welfare rules

British press attitudes towards the EU's global presence:from the Russian-Georgian War to the 2009 Copenhagen Summit

This article surveys the way in which British print media have presented the European Union (EU)'s global presence in the international arena by analysing two case studies which reflect two very distinctive areas of EU foreign policy: global climate change policy and the policy towards Russia. It employs frame analysis, allowing for the identification of the way in which the discourse of the press was categorized around a series of central opinions and ideas. Frames underscore the connections made by journalists between different events, policies or phenomena and their possible interpretations. The analysis highlights that acting through the common framework of the EU rather than unilaterally was a strategy preferred by the British press. These findings are in stark contrast with the deep Euroscepticism which characterizes press attitudes towards most policy areas, and is often considered to be rooted in the British political culture, media system, public opinion or the longstanding tradition of viewing the European continent as the other

The potential for grid defection of small and medium sized enterprises using solar photovoltaic, battery and generator hybrid systems

Grid-tied solar photovoltaic (PV) systems enable lowercost electricity for small and medium size enterprises (SMEs) than current many providers of grid electricity in the U.S. These economic realities threaten conventional electric utilities, which have begun manipulating rate structures to reduce the profitability of distributed generation (DG), as well as putting arbitrary caps on DG in their service territories. SMEs may still reduce electricity costs, if they can grid defect with hybrid captive power systems made up of solar PV, battery and generator subsystems. This paper analyzes the technical and economic viability for hybrid solar systems deployed in the commercial sector to enable self-generation. Specifically, for the first time, the economics of grid defection are analyzed for three case studies of SMEs in the northern U.S., which represent a challenging technical case because of long dark winters, but also have high utility costs. The results of the simulations make it clear that grid defection is already viable for SMEs with the current prices for all components in the solar hybrid system. These results were consistent across scale, load-profile, and utility rate. These economic projections included no government incentives or subsidies and can thus be considered extremely conservative for the specific case studies. Policy changes are discussed for electric utilities to avoid the potential of a utility death spiral in this and similar performing locations
