Book Description
The availability of oil and gas for future generations continues to provoke international debate. In 2005, the first edition of Resources to Reserves found that the known hydrocarbon resources were sufficient to sustain likely growth for the foreseeable future. Yet the book also predicted that developing oil and gas resources - and bringing them to market - would become more technically demanding. Resources to Reserves 2013 - a comprehensive update to the 2005 edition - confirms these earlier findings and investigates whether oil and gas resources can be produced at a reasonable cost and in a timely manner, while also protecting environmentally sensitive areas. Released amid a boom in shale gas and oil development in North America that is transforming the global energy landscape, the book surveys the cutting-edge technologies needed to find, produce and bring these reserves to the market, and it reviews the challenges on greenhouse gas emissions associated with fossil fuel production. With renewed interest in coal as a potential source of liquid and gaseous fuels, it also looks at technology advances for this fossil fuel.

Book Description
A new road user charge system based on an actual miles traveled basis, or vehicle miles of travel (VMT), is recommended to replace motor fuel taxes, which are in jeopardy due to new vehicle propulsion technologies. This charge would provide a means for crediting states or sub-state jurisdictions for the miles of travel occurring within their boundaries by collecting data from vehicles equipped with intelligent vehicle and GPS technologies. Researchers conclude that a convenient and flexible road user charge system can be designed which will ensure a stable source of revenue for the highway system.

Book Description
The various Indo-European branches had a shared linguistic and cultural origin in prehistory, and this book sets out to overcome the difficulties about understanding the gods who were inherited by the later literate cultures from this early “silent” period by modelling the kind of society where the gods could have come into existence. It presents the theory that there were ten gods, who are conceived of as reflecting the actual human organization of the originating time. There are clues in the surviving written records which reveal a society that had its basis in the three concepts of the sacred, physical force, and fertility (as argued earlier by the French scholar, Georges Dumézil). These concepts are now seen as corresponding to the old men, young men, and mature men of an age-grade system, and each of the three concepts and life stages is seen to relate to an old and a young god. In addition to these six gods, and to two kings who relate in positive and negative ways to the totality, there is a primal goddess who has a daughter as well as sons. The gods, like the humans of the posited prehistoric society, are seen as forming a four-generation set originating in an ancestress, and the theogony is explored through stories found in the Germanic, Celtic, Indian, and Greek contexts. The sources are often familiar ones, such as the Edda, the Mabinogi, Hesiod’s Theogony, and the Rāmāyaṇa, but selected components are looked at from a fresh angle and, taken together with less familiar and sometimes fragmentary materials, yield fresh perspectives which allow us to place the Indo-European cosmology as one of the world’s indigenous religions. We can also gain a much livelier sense of the original culture of Europe before it was overlaid by influences from the Near East in the period of literacy. The gods themselves continue to exert their fascination, and are shown to reflect a balance between the genders, between the living and the ancestors, and between peaceful and warlike aspects expressed at the human level in alternate succession to the kingship.

Book Description
This volume presents a comprehensive exposition of both the prehistory and medieval history of the whole of Scandinavia. The first part of the volume surveys the prehistoric and historic Scandinavian landscape and its natural resources, and tells how man took possession of this landscape, adapting culturally to changing natural conditions and developing various types of community throughout the Stone, Bronze and Iron Ages. The rest - and most substantial part of the volume - deals with the history of Scandinavia from the Viking Age to the end of the Scandinavian Middle Ages (c. 1520). The external Viking expansion opened Scandinavia to European influence to a hitherto unknown degree. A Christian church organisation was established, the first towns came into being, and the unification of the three medieval kingdoms of Scandinavia began, coinciding with the formation of the unique Icelandic 'Free State'.

Book Description
All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.
