Download or read book Dayside and Polar Cap Aurora written by Per Even Sandholt and published by Springer Science & Business Media. This book was released on 2006-05-02 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: The auroral emissions in the upper atmosphere of the polar regions of the Earth are evidence of the capture of energetic particles from the Sun, streaming by the Earth as the solar wind. These auroral emissions, then, are a window to outer space, and can provide us with valuable information about electrodynamic coupling processes between the solar wind and the Earth's ionosphere and upper atmosphere. Studying the physics of these phenomena extends our understanding of our plasma universe. Ground-based remote-sensing techniques, able to monitor continuously the variations in the signatures of aurorae, in combination with in-situ satellite and rocket measurements, promise to advance dramatically our understanding of the physical processes taking place at the interface of the atmospheres of the Earth and the Sun. Decoding their complexity brings us closer to reliable prediction of communication environments, especially at high latitudes. This understanding, in turn, will help us resolve problems of communication and navigation across polar regions.

Available in PDF, EPUB and Kindle. Book excerpt: Only a few centuries ago, we knew very little about our planet Earth. The Earth was considered flat by many although it was postulated by a few like Aristotle that it is spherical based on observations that included the study of lunar eclipses. Much later, Christopher Columbus successfully sailed to the West to discover the New World and Ferdinand Magellan’s ship circumnavigated the globe to prove once and for all that the Earth is indeed a sphere. Worldwide navigation and explorations that followed made it clear that the Earth is huge and rather impossible to study solely by foot or by water. The advent of air travel made it a lot easier to do exploratory studies and enabled the mapping of the boundaries of continents and the oceans. But aircraft coverage was limited and it was not until the satellite era that full c- erage of the Earth’s surface became available. Many of the early satellites were research satellites and that meant in part the development of engineering measurement systems with no definite applications in mind. The Nimbus-5 Electrically Scanning Microwave Radiometer (ESMR) was a classic case in point. The sensor was built with the idea that it may be useful for meteorological research and especially rainfall studies over the oceans, but success in this area of study was very limited.

Download or read book Stability and Stabilization of Enzymes written by W.J.J. van den Tweel and published by Elsevier. This book was released on 2013-10-22 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings contain most of the oral presentations and posters of the international symposium on Stability and Stabilization of Enzymes held in Maastricht in November 1992. They provide a comprehensive overview of the state-of-the-art in this field. The possible applications of enzymes are enormous. Years of development have seen many enzymes brought onto the market, but they are still expensive to use. Therefore, their efficient application is a prerequisite for common usage. One of the main factors for this efficiency is the stability of the enzymes. The topics thus ranged from the extensive fundamental thermodynamic knowledge gathered in academic research to the practical applied knowledge built up in industry during the time that enzymes have been produced commercially. The subject Stability and Stabilization of Enzymes was discussed from various points of view, as was reflected in the themes of the symposium sessions. In the session on Fundamentals of Enzyme Stabilisation the thermodynamic background of the phenomenon was highlighted. In yet another session, the recently developed analytical tools to measure enzyme stability and stabilisation were discussed. Further sessions comprised the physical, chemical and biological ways to obtain enzyme stabilisation and finally, the industrial practice of enzyme stabilisation was treated by representatives of the world's most important enzyme producers. The book will be of interest to researchers in universities and industry in the fields of biochemistry, enzymology and biotechnology.

Download or read book The Biology of Polar Regions written by D. N. Thomas and published by OUP Oxford. This book was released on 2008-03-20 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is now an increased awareness of the importance of polar regions in the Earth system, as well as their vulnerability to anthropogenic derived change, including of course global climate change. This new edition offers a concise but comprehensive introduction to polar ecology and has been thoroughly revised and updated throughout, providing expanded coverage of marine ecosystems and the impact of humans. It incorporates a detailed comparison of the Arctic and Antarctic systems, with a particular emphasis on the effects of climate change, and describes marine, freshwater, glacial, and terrestrial habitats. This breadth of coverage is unique in the polar biology literature. As with other titles in the Biology of Habitats Series, particular emphasis is placed on the organisms that dominate these extreme environments although pollution, conservation and experimental aspects are also considered. This accessible text is suitable for both senior undergraduate and graduate students taking courses in polar ecology, often as part of a wider marine biology degree programme. It will also be of value and use to the many professional ecologists and conservation biologists requiring a concise overview of the topic.
