ABSTRACTBeginning in 1952, waste materials, including volatile organic compounds (VOCs)contaminated with transuranic radionuclides, were generated during the fabrication, assembly, and processing of nuclear weapons components in the US Department of Energy (DOE) weapons productions complex at the Rocky Flats Plant (RFP). Following processing and containerization, drums were shipped to the Subsurface Disposal Area (SDA) at the Idaho National Engineering and Environmental Laboratory (INEEL). During 1968 approximately 9,691 drums were buried there.In subsequent years, observations made during drum retrieval studies indicated that many of the drums were compromised on impact or suffered physical damage by compaction equipment shortly after burial. Corrosion also appears significant on drums buried for a few years. A large vadose-zone contaminant plume composed of solvents buried in the drums has been found beneath the burial area.Phase partitioning calculations show it unlikely that separate-phase solvent has leaked from the compromised drums deep into the soil profile or that solvents have dissolved into infiltrating water. Rather, it appears that the solvents are evaporating out of the barrels into the air phase and further partitioning from there throughout the subsurface.This paper describes the history of mixed wastes buried at the SDA, phase partitioning, and preliminary computer simulation results on gas contaminant mobility in the vadose zone.

In June 1993, the US Department of Energy announced the decision to shut down production of nuclear weapon components at its Rocky Flats plant located near Denver, Colorado, and begin a long-term clean-up of the facility. Faced with very severe economic impacts from downsizing the facility (approximately 8,000 employees at its peak), federal, state, and local governments formed a Community Reuse Organization to develop and implement strategies to mitigate the effects of displaced workers and lost income. This paper describes an innovative partnership concept, specifically aimed at providing technology-based start-up companies with world-class university expertise that they otherwise could not afford.

Joseph Späh had to feed his dog; nothing strange about that. The problem was that Ulla, an Alsatian, was mostly confined to the freight room—off limits to passengers. Had everything gone according to schedule, this would not have been an issue either, except for gruff remarks from crewmen not appreciating the needs of this canine friend and co-worker in Späh’s stage act. But this flight did not go according to plan, and Späh’s frequent visits to the rear of the Hindenburg would give him problems in the years to come. The US Department of Energy, and its counterparts in Europe and Japan, are currently spending billions on developing the use of hydrogen for future energy applications—for example, as a fuel for cars and buses. The main advantage is the clean combustion of this fuel: two molecules of hydrogen gas will combine with one molecule of oxygen and give two molecules of water. The future belongs, perhaps, to the ‘hydrogen economy’, but unfortunately for its proponents, the popular history of hydrogen as a fuel is bound up with the tragedy of the Hindenburg. We will get back to Joseph Späh’s poor dog in a while, but for now ponder the fact that over the dog, and above everyone else aboard the comfortable and luxurious Hindenburg , there were huge ‘bags’ filled with hydrogen—the lightest of all the elements, with only one proton and one electron. It has the lowest density of any gas, and is formed by two hydrogen atoms combined together via a single chemical bond, made by sharing the two negatively charged electrons between the two positively charged nuclei. This H2 gas had carried the world’s largest airship from Frankfurt to Lakehurst outside New York, and before that on successful tours all over the globe during the preceding year. These days, we tend to wonder how people could even contemplate the idea of travelling around in what can be described as a flying bomb.

This article focuses on the work done at GE from 1960s to the early 1980s. GE funded the project of developing a full pressure/full temperature model of the same size. Test facilities were also built and run to gather data on potential problems such as: long term effects of partial channel water cooling on erosion, corrosion, and deposition; water supply, distribution and collection in the outer casing; materials testing with contaminated fuels. The results of the Electric Power Research Institute (EPRI) program were sufficiently encouraging that GE and EPRI decided to advocate a bigger project to the US Department of Energy to demonstrate the concept in utility size components. GE dropped work on water cooling in the early 1980s. Part of the reason was concern of instabilities in the boiling water.

Migration and Modernities recovers a comparative literary history of migration by bringing together scholars from the US and Europe to explore the connections between migrant experiences and the uneven emergence of modernity. The collection initiates transnational, transcultural and interdisciplinary conversations about migration in the eighteenth and nineteenth centuries, demonstrating how mobility unsettles the geographic boundaries, temporal periodization, and racial categories we often use to organize literary and historical study. Migrants are by definition liminal, and many have existed historically in the spaces between nations, regions or ethnicities. In exploring these spaces, Migration and Modernities also investigates the origins of current debates about belonging, rights, and citizenship. Its chapters traverse the globe, revealing the experiences — real or imagined — of eighteenth- and nineteenth-century migrants, from dispossessed Native Americans to soldiers in South America, Turkish refugees to Scottish settlers. They explore the aesthetic and rhetorical frameworks used to represent migrant experiences during a time when imperial expansion and technological developments made the fortunes of some migrants and made exiles out of others. These frameworks continue to influence the narratives we tell ourselves about migration today and were crucial in producing a distinctively modern subjectivity in which mobility and rootlessness have become normative.

The Relationship

This essay explores the evolving international relationship of the two national park agencies that in 1968 began to offer joint training classes for protected-area managers from around the world. Within the British settler societies that dominated nineteenth century park-making, the United States’ National Park Service (NPS) and Canada’s National Parks Branch were the most closely linked and most frequently cooperative. Contrary to campfire myths and nationalist narratives, however, the relationship was not a one-way flow of information and motivation from the US to Canada. Indeed, the latter boasted a park bureaucracy before the NPS was established. The relationship of the two nations’ park leaders in the half century leading up to 1968 demonstrates the complexity of defining the influences on park management and its diffusion from one country to another.

The aim of the Ukrainian Bureau in Washington was propaganda of Ukrainian question among US government and American publicity in general. Functioning of the Bureau is not represented non in Ukrainian neither in foreign historiographies, so that’s why the main goal of presented paper is to investigate its activity. The research is based on personal papers of Ukrainian diaspora representatives (O. Granovskyi, E. Skotzko, E. Onatskyi) and articles from American and Ukrainian newspapers. The second mass immigration of Ukrainians to the US (1914‒1930s) has often been called the «military» immigration and what it lacked in numbers, it made up in quality. Most immigrants were educated, some with college degrees. The founder of the Ukrainian Bureau Eugene Skotzko was born near Western Ukrainian town of Zoloczhiv and immigrated to the United States in late 1920s after graduating from Lviv Polytechnic University. In New York he began to collaborate with OUN member O. Senyk-Hrabivskyi who gave E. Skotzko task to create informational bureau for propaganda of Ukrainian case. On March 23 1939 the Bureau was founded in Washington D. C. E. Skotzko was an editor of its Informational Bulletins. The Bureau biggest problem was lack of financial support. It was the main reason why it stopped functioning in May 1940. During 14 months of functioning Ukrainian Bureau in Washington posted dozens of informational bulletins and send it to hundreds of addressees; E. Skotzko, as a director, personally wrote to American governmental institutions and foreign diplomats informing about Ukrainian problem in Europe. Ukrainian Bureau activity is an inspiring example for those who care for informational policy of modern Ukraine.Keywords: Ukrainian small encyclopedia, Yevhen Onatsky, journalism, worldview, Ukrainian state.

This book challenges a dominant hypothesis in the study of epidemics. From an interdisciplinary array of scholars, a consensus has emerged: invariably, epidemics in past times provoked class hatred, blame of the ‘other’, or victimization of the diseases’ victims. It is also claimed that when diseases were mysterious, without cures or preventive measures, they more readily provoked ‘sinister connotations’. The evidence for these assumptions, however, comes from a handful of examples—the Black Death, the Great Pox at the end of the sixteenth century, cholera riots of the 1830s, and AIDS, centred almost exclusively on the US experience. By investigating thousands of descriptions of epidemics, reaching back before the fifth-century BCE Plague of Athens to the eruption of Ebola in 2014, this study traces epidemics’ socio-psychological consequences across time and discovers a radically different picture. First, scholars, especially post-AIDS, have missed a fundamental aspect of the history of epidemics: their remarkable power to unify societies across class, race, ethnicity, and religion, spurring self-sacrifice and compassion. Second, hatred and violence cannot be relegated to a time when diseases were mysterious, before the ‘laboratory revolution’ of the late nineteenth century: in fact, modernity was the great incubator of a disease–hate nexus. Third, even with diseases that have tended to provoke hatred, such as smallpox, poliomyelitis, plague, and cholera, blaming ‘the other’ or victimizing disease bearers has been rare. Instead, the history of epidemics and their socio-psychological consequences has been richer and more varied than scholars and public intellectuals have heretofore allowed.
