Since early recorded history, people have been harnessing the energy of the wind. In the United States in the late 19th century, settlers began using windmills to pump water for farms and ranches, and later, to generate electricity for homes and industry. Industrialism led to a gradual decline in the use of windmills. The steam engine replaced European water-pumping windmills, and in the 1930s, the Rural Electrification Administration's programs brought inexpensive electric power to most rural areas in the United States. However, industrialization also sparked the development of larger windmills, wind turbines, to generate electricity.

An Environmental History of the World is a concise history, from Ancient to Modern times, of the interaction between human societies and the other forms of life that inhabit our planet. This original work follows a chronological path through the history of mankind, in relationship to ecosystems around the world. Each chapter concentrates on a general period in human history which has been characterised by large scale changes in the relationship of human societies to the biosphere, and gives three case-studies that illustrate the significant patterns occurring at that time. Little environmental or historical knowledge is assumed from the reader in this introduction to environmental history.
Ecosystem" is an intuitively appealing concept to most ecologists, but, in spite of its widespread use, the term remains diffuse and ambiguous. The authors of this book argue that previous attempts to define the concept have been derived from particular viewpoints to the exclusion of others equally possible. They offer instead a more general line of thought based on hierarchy theory. Their contribution should help to counteract the present separation of subdisciplines in ecology and to bring functional and population/community ecologists closer to a common approach. Developed as a way of understanding highly complex organized systems, hierarchy theory has at its center the idea that organization results from differences in process rates. To the authors the theory suggests an objective way of decomposing ecosystems into their component parts. The results thus obtained offer a rewarding method for integrating various schools of ecology.
Understand Quantitative Radiobiology from a Radiation Biophysics PerspectiveIn the field of radiobiology, the linear-quadratic (LQ) equation has become the standard for defining radiation-induced cell killing.

Deserts, whether hot or cold, are considered to be one of the most difficult environments for living systems, lacking the essential free water which ac counts for approximately 60-70% of their body mass and more than 98% of their constituent atoms {Macfarlane 1978}. Amongst vertebrates, reptiles are usually thought of as the animals most adapted or suited to such environments because of their diurnal habit, based on a need for external heat, and their ability to survive far from obvious sources of water. This impression is rein forced when one examines the composition of vertebrate faunae characteristic of deserts and arid zones: reptiles predominate and they are often the only vertebrates to be found in hyper-arid areas, such as some parts of the Sahara {Monod 1973}. I recently had occasion to examine this assumption carefully, however, and was led inexorably to the conclusion that reptiles represent a particularly successful desert group, not because of their evolution of superior adaptations, but because of their possession of a basic suite of behavioural and physiologi cal characteristics that suit them uniquely to this very resource-limited environment {Bradshaw 1986a}. These fundamental reptilian characteristics are: 1. their low rates of metabolism, compared with birds and mammals, which result in extremely low rates of resource utilisation and lead to considerable economy in the handling of water 2.
Women against cruelty is the first book to explore women’s leading role in animal protection in nineteenth-century Britain, drawing on rich archival sources. Women founded bodies such as the Battersea Dogs’ Home, the Royal Society for the Protection of Birds and various groups that opposed vivisection. They energetically promoted better treatment of animals, both through practical action and through their writings, such as Anna Sewell’s Black Beauty. Yet their efforts were frequently belittled by opponents, or decried as typifying female ‘sentimentality’ and hysteria. Only the development of feminism in the later Victorian period enabled women to show that spontaneous fellow-feeling with animals was a civilising force. Women’s own experience of oppressive patriarchy bonded them with animals, who equally suffered from the dominance of masculine values in society, and from an assumption that all-powerful humans were entitled to exploit animals at will.
The closed nature of the Soviet Union, combined with the WestÆs intellectual paradigm of Communist totalitarianism prior to the 1970s, have led to a one-dimensional view of Soviet history, both in Russia and the West. The opening of former Soviet archives allows historians to explore a broad array of critical issues at the local level. Provincial Landscapes is the first publication to begin filling this enormous gap in scholarship on the Soviet Union, pointing the way to additional work that will certainly force major reevaluations of the nationÆs history.Focusing on the years between the Revolution and StalinÆs death, the contributors to this volume address a variety of topics, including how political events and social engineering played themselves out at the local level; the construction of Bolshevik identities, including class, gender, ethnicity, and place; the Soviet cultural project; and the hybridization of Soviet cultural forms. In showing how the local is related to the larger society, the essays decenter standard narratives of Soviet history, enrich the understanding of major events and turning points in that history, and provide a context for the highly visible socio-political and cultural role individual Russian provinces began to play after the breakup of the Soviet Union.
The growth of the national debt, which is considered unsustainable under current policies, continues to be one of the central issues of domestic federal policymaking. Addressing a federal budget deficit that is unsustainable over the long run involves choices. Fundamentally, the issues require deciding what government goods, services, and transfers are worth paying taxes for. Most people would agree that the country benefits from a wide range of government services-air traffic controllers, border security, courts and corrections, and so forth-provided by the federal government. Yet federal government provision of goods and services comprises only a modest portion of the federal budget. Transfers, including interest payments, accounted for around 75% of the federal budget. Central findings of this analysis include the following: A comparatively small share of federal spending is for the direct provision of domestic government goods and services. Transfers and payments to persons and to state and local governments constitute most of federal spending, about 75% of all federal spending. Defense spending, accounting for about 15% of federal spending, has declined as a share of output over the past 35 years, but it also tends to vary depending, in part, on the presence and magnitude of international conflicts. The problem with the debt lies not in the past but in the future, as growth in spending for health and Social Security is projected to continue faster than the economy as a whole. The increase in deficits and debt, in turn, leads to a significant increase in interest payments. Because much of the pressure on future spending arises from imbalances in Social Security and Medicare Part A (Hospital Insurance) trust funds, keeping these funds and their sources of financing intact is a concern that could constrain choices. Preserving entitlements would likely require significant increases in taxes, such as raising rates, reducing tax expenditures, increasing other taxes, or introducing new revenue sources. Reductions in discretionary spending are insufficient to reduce the deficit to a sustainable level, so limiting taxes as a percentage of output or constraining the overall size of the government to current levels would likely require significant cuts in mandatory spending, including entitlement programs such as Social Security, Medicare, and Medicaid. Because the federal government provides about one-fifth of the revenue for state and local governments, cutbacks in transfers to these governments may, in part, shift the burden of providing services from the national to subnational governments rather than altering the overall size of government services.
