Discharge in Long Air Gaps


Book Description

'Discharge in Long Air Gaps' presents self-consistent predictive dynamic models of positive and negative discharges in long air gaps. Equivalent models are also derived to predict lightning parameters based on the similarities between long air gap discharges and lightning flashes. Comparisons between computed and experimental results for various test configurations are presented and discussed.




EcoRegions of Alaska


Book Description

Produced as a framework for organizing and interpreting environmental data for inventory, monitoring, and research efforts. The descriptions of the 20 ecoregions of Alaska contained in this guide were derived by synthesizing information on the geographic distribution of environmental factors such as climate, terrain, soils, and vegetation. The specific procedures and materials used to delineate the ecoregion boundaries are documented, and the environmental characteristics in each ecoregion are described. Accompanied by a full-color oversize map of the ecoregions, their boundaries, and transitional areas. 42 full-color photos.




A Philosophical View of the Ocean and Humanity


Book Description

This book is about the ocean and about the future. It is written in two modes, a concerned analytical scientific mode and an intuitive artistic mode in which the ocean is given a voice. The disconnect in the relationship between human dependency on and feelings about the ocean is examined in a dialogue between these two modes. The book illustrates how science and the arts can be connected to increase our awareness of the state of the ocean and support behavioural change. This book is intended for everyone who would like to contribute to the sustainable use of the ocean. Includes forewords by Alice Newton, University of Algarve, Portugal and Martin Visbeck, GEOMAR, Helmholtz Centre for Ocean Research, Kiel, Germany.

Yvain


Book Description

The twelfth-century French poet Chrétien de Troyes is a major figure in European literature. His courtly romances fathered the Arthurian tradition and influenced countless other poets in England as well as on the continent. Yet because of the difficulty of capturing his swift-moving style in translation, English-speaking audiences are largely unfamiliar with the pleasures of reading his poems. Now, for the first time, an experienced translator of medieval verse who is himself a poet provides a translation of Chrétien’s major poem, Yvain, in verse that fully and satisfyingly captures the movement, the sense, and the spirit of the Old French original. Yvain is a courtly romance with a moral tenor; it is ironic and sometimes bawdy; the poetry is crisp and vivid. In addition, the psychological and the socio-historical perceptions of the poem are of profound literary and historical importance, for it evokes the emotions and the values of a flourishing, vibrant medieval past.

Knowledge Democracy


Book Description

Knowledge democracy is an emerging concept that addresses the relationships between knowledge production and dissemination, as well as the functions of the media and democratic institutions. Although democracy has been the most successful concept of governance for societies for the last two centuries, representative democracy, which became the hallmark of advanced nation-states, seems to be in decline. Media politics is an important factor in the downfall of the original meaning of representation, yet more direct forms of democracy have not yet found an institutional embedding. Further, the Internet has also drastically changed the rules of the game, and a better educated public has broad access to information, selects for itself which types to examine, and ignores media filters. Some citizens have even become "media" themselves. In a time where the political agendas are filled with combatting so-called evils, new designs for the relationships between science, politics and media are needed. This book outlines the challenges entailed in pursuing a vital knowledge democracy.




Carbon Cycling in the Baltic Sea


Book Description

The Baltic Sea is an area extensively explored by the oceanographers. Hence it is one of the most often described marine areas in the scientific literature. However, there are still several fields which are poorly investigated and reported by scientists. One of them is the carbon cycle of the Baltic Sea. Although it is believed the shelf seas are responsible for about 20% of all marine carbon dioxide uptake, while they constitute only 7% of the whole sea surface, still a scientific debate exists on the role of the Baltic Sea in the global carbon cycle. “Carbon cycle of the Baltic Sea” is intended to be a comprehensive presentation and discussion of state of the art research by biogeochemists involved in the Baltic Sea carbon cycle research. This work presents both qualitative and quantitative descriptions of the main carbon flows in the Baltic Sea as well as their possible shifts induced by climatic and global change.
