In the half century since paleontologists began finding putative microfossils in Precambrian sedimentary rocks, it has become apparent that not only is most of life’s history absent from the visible fossil record, but huge sectors of extant life remain to be discovered. Until the early 1980s, the only way to identify and study species of microbes—many if not most of which are morphologically indistinct from each other—was by growing them in the laboratory, isolating the separate colonies of organisms that developed as they reproduced, and then noting differences and similarities in what they consumed and produced. But the capacity to read the information in microbial genes that was developed in the 1980s and 1990s opened an entirely new world for study—much as the invention of the microscope had in the eighteenth century—and laid bare the unnerving fact that the vast majority of microbes on the planet had been boycotting the microbiologists’ carefully prepared cultures. Microbiologists had spent almost a century painstakingly cultivating, isolating, and classifying microorganisms, and yet they had failed to identify the most abundant microbes in natural waters, sediments, and soils. Indeed, it now appears that the hundreds of thousands of microbes named and maintained in the world’s bacteria zoos, or “culture collections,” invaluable as they are, comprise but a tiny and somewhat random sampling of the microbial world. These microbial cultures provide the only means by which biologists can directly manipulate and study the biochemistry and physiology of this huge sector of life in the laboratory—but they are distinguished more by their ability to prosper under laboratory conditions than by their importance in natural ecosystems. In the past few years, application of new techniques from molecular biology has resulted in the discovery of thousands of strange new types of microorganisms, and there is the implication of countless more: in the twenty-first century we find ourselves unexpectedly gathered at the threshold of a new world, looking not to Mars or Jupiter or to some distant galaxy, but gazing awestruck at the mud beneath our feet and the water in our seas.

Making sense of Brown v. Board of Education, decided the same year I was born, and understanding what it did and did not achieve have occupied me since I can remember. When the fiftieth anniversary of the ruling arrived, scholars and media pundits debated whether the case deserved its landmark status and whether it had delivered in any meaningful way on the promise of racial equality for African Americans—or if it instead was ineffectual or counterproductive. Those are important questions, and this book grapples with them. Yet largely missing from the public discussions was the enormous influence of Brown in schools beyond race. The Supreme Court’s embrace of the ideal of equal opportunity and its critique of the separate-but-equal approach to education transformed the treatment of immigrants, students learning English, girls, students with disabilities, and poor students in American schools; religion in schools; school choice; and social science evidence about schooling—and the story of these changes deserves telling. That is what this book aims to do, even as it tells of a mixed legacy of Brown in these other contexts while also tracing reverberations of Brown outside the United States. To tell these stories is to engage with public policy debates over separate versus mixed instruction in meeting the needs of varied kinds of students. Nested within larger disputes over the viability of the racial integration ideal, this effort also explores the emergence of Brown as a resource for enterprising and visionary reformers concerned with gender, disability, religion, and other topics. The legacies of Brown invite a look at the capacity of individuals to push and achieve change using law and social science; the histories are interconnected with social movements as well as unexpected consequences of resulting reforms. Chapter 1 offers an analysis of what this landmark U.S. Supreme Court case did and did not accomplish when it banned official racial segregation in public schools. I consider whether the lawyers’ goal ever was integration, defined to mean both the side-by-side instruction of students of different races and the creation of school communities with a sense of common purpose and membership bridging different identities, histories, and past opportunities.

Thermal design and packaging strategy of a prototype dual-loop vapor compression refrigeration cooling system, developed as a pilot model for thermal management of high performance CMOS based MCMs, is introduced in this paper. The cooling system was comprised of two separated refrigeration units providing low temperature cooling via a dual-path cooling module (evaporator) mounted on a CPU-MCM package. Cooling capacity for each refrigeration unit was controlled ranging from 250W to 2500W with a refrigerant evaporating temperature at −25 degree centigrade. The CPU-MCM mounted with the refrigerat

The main objective in optimizing train control is to eliminate the waist associated with classical design where train separation is determined through the use of “worst case” assumptions that are invariant to the system. In fact, the worst case approach has been in place since the beginning of train control systems. Worst case takes the most conservative approach to the determination of train stopping distance, which is the basis for design of virtually all train control. This leads to stopping distances that could be far more that actually required under the circumstances at the time the trai

Circulation control technology has proven itself useful in the area of short take-off and landing (STOL) fixed wing aircraft by decreasing landing and takeoff distances, increasing maneuverability and lift at lower speeds. The application of circulation control technology to vertical take-off and landing (VTOL) rotorcraft could also prove quite beneficial. Successful adaptation to helicopter rotor blades is currently believed to yield benefits such as increased lift, increased payload capacity, increased maneuverability, reduction in rotor diameter and a reduction in noise. Above all, the addi

Created in 1978, the Solid Waste Authority of Palm Beach County (Authority) has developed an “award winning” solid waste management system that includes franchised solid waste collections and the following facilities to service the residents and businesses in Palm Beach County, Florida: • North County Resource Recovery Facility (NCRRF); • Residential and Commercial Recovered Materials Processing Facility; • Five Transfer Stations; • Class I Landfill; • Class III Landfill; • Biosolids Pelletization Facility; • Ferrous Processing Facility; • Woody Waste Recycling Facility; • Composting Facility;
