The Forest Primary Production Research Group was born in the Department of S- viculture, University of Helsinki in the early 1970s. Intensive ?eld measurements of photosynthesis and growth of forest vegetation and use of dynamic models in the interpretation of the results were characteristic of the research in the group. Electric instrumentation was based on analogue techniques and the analysis of the obtained measurements was based on self-written programs. Joint research projects with the Research Group of Environmental Physics at the Department of Physics, lead by Taisto Raunemaa (1939–2006) started in the late 1970s. The two research groups shared the same quantitative methodology, which made the co-operation fruitful. Since 1980 until the collapse of the Soviet Union the Academy of Finland and the Soviet Academy of Sciences had a co-operation program which included our team. The research groups in Tartu, Estonia, lead by Juhan Ross (1925–2002) and in Petrozawodsk, lead by Leo Kaipiainen (1932–2004) were involved on the Soviet side. We had annual ?eld measuring campaigns in Finland and in Soviet Union and research seminars. The main emphasis was on developing forest growth models. The research of Chernobyl fallout started a new era in the co-operation between forest ecologists and physicists in Helsinki. The importance of material ?uxes was realized and introduced explicitly in the theoretical thinking and measurements.

It is the distant future. The world known as Virga is a fullerene balloon three thousand kilometers in diameter, filled with air, water, and floating chunks of rock. The humans who live in this vast environment must build their own fusion suns and "towns" —enormous wood and rope wheels that are spun for centripetal gravity. This complex and fascinating world is the setting for the novels of Virga, Karl Schroeder's interstellar far-future space habitat sealed off from contamination by the rest of the inhabited universe. These books have set a high standard for hard SF adventure in the last decade, and now the first two novels, Sun of Suns and Queen of Candesce, are brought out for the first time in one trade paper omnibus. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Today, air power is a vital component of the U.S. armed forces. James Libbey, in Alexander P. de Seversky and the Quest for Air Power, highlights the contributions of an aviation pioneer who made much of it possible. Graduating from the Imperial Russian Naval Academy at the start of World War I, de Seversky lost a leg in his first combat mission. He still shot down thirteen German planes and became the empire's most decorated combat naval pilot. While serving as a naval attache in the United States in 1918, de Seversky elected to escape the Bolshevik Revolution and offered his services as a pilot and consulting engineer to the U.S. War Department. He proved inventive both in the technology of advanced military aircraft and in the strategy of exercising air power. He worked for famed aviation advocate Gen. William "Billy" Mitchell, who encouraged the naturalized citizen to patent his inventions, such as an in-flight refueling system and a gyroscopically synchronized bombsight. His creative spirit then spurred him to design and manufacture advanced military aircraft. When World War II broke out in Europe, de Seversky became America's best-known philosopher, prophet, and advocate for air power, even serving as an adviser to the chief of staff of the U.S. Air Force. The highlight of his life occurred in 1970 when the Aviation Hall of Fame enshrined de Seversky for "his achievements as a pilot, aeronautical engineer, inventor, industrialist, author, strategist, consultant, and scientific advances in aircraft design and aerospace technology." This book will appeal to readers with a special interest in military history and to anyone who wants to learn more about American air power's most important figures.
