The ecosystems present a great diversity worldwide and use various functionalities according to ecologic regions. In this new context of variability and climatic changes, these ecosystems undergo notable modifications amplified by domestic uses of which it was subjected to. Indeed the ecosystems render diverse services to humanity from their composition and structure but the tolerable levels are unknown. The preservation of these ecosystemic services needs a clear understanding of their complexity. The role of the research is not only to characterise the ecosystems but also to clearly define the tolerable usage levels. Their characterisation proves to be important not only for the local populations that use it but also for the conservation of biodiversity. Hence, the measurement, management and protection of ecosystems need innovative and diverse methods. For all these reasons, the aim of this book is to bring out a general view on the biogeochemical cycles, the ecological imprints, the mathematical models and theories applicable to many situations.

This book was released on 2016-06-07. Jellyfish available in PDF, EPUB and Kindle. An introduction to these bizarre and beautiful creatures of the sea, filled with color photos and illustrations: “Fascinating.”—Boing Boing Jellyfish are the oldest multi-organed life form on the planet, having inhabited the ocean for more than five hundred million years. With their undulating umbrella-shaped bells and sprawling tentacles, they are compelling and gorgeous, strange and dangerous. In many places they’re also vastly increasing in number, and these population blooms may be an ominous indicator of the rising temperatures and toxicity of the oceans. Jellyfish presents these aquarium favorites in all their glory. Fifty unique species, from the purple people eater to black sea nettles, are presented in stunning photos along with the most current scientific information on their anatomy, history, distribution, position in the water, and environmental status. Foremost jellyfish expert Lisa-ann Gershwin provides an insightful look at the natural history and biology of each of these spellbinding creatures, plus a timely take on their place in the rapidly changing and deteriorating condition of the oceans. Learn about immortal jellyfish who live and die and live again—as well as those who camouflage themselves amid sea grasses and shells, hiding in plain sight. Discover the jellyfish that’s the world’s most venomous animal, and the jellyfish that helped scientists win the Nobel Prize. They’re all here and more in this delightful volume. “A thorough coverage of jellyfish history, biology and ecology. Gershwin, a marine biologist who has discovered over 200 new species of jellyfish, does an excellent job of combining a compelling narrative of 50 different jellyfish with luscious, I-can’t-believe-they’re-real photos.”—Boing Boing

Download and read online ebook Sonochemistry and the Acoustic Bubble write by Franz Grieser. This book was released on 2015-04-16. Sonochemistry and the Acoustic Bubble available in PDF, EPUB and Kindle. Sonochemistry and the Acoustic Bubble provides an introduction to the way ultrasound acts on bubbles in a liquid to cause bubbles to collapse violently, leading to localized 'hot spots' in the liquid with temperatures of 5000° celcius and under pressures of several hundred atmospheres. These extreme conditions produce events such as the emission of light, sonoluminescence, with a lifetime of less than a nanosecond, and free radicals that can initiate a host of varied chemical reactions (sonochemistry) in the liquid, all at room temperature. The physics and chemistry behind the phenomena are simply, but comprehensively presented. In addition, potential industrial and medical applications of acoustic cavitation and its chemical effects are described and reviewed. The book is suitable for graduate students working with ultrasound, and for potential chemists and chemical engineers wanting to understand the basics of how ultrasound acts in a liquid to cause chemical and physical effects. - Experimental methods on acoustic cavitation and sonochemistry - Helps users understand how to readily begin experiments in the field - Provides an understanding of the physics behind the phenomenon - Contains examples of (possible) industrial applications in chemical engineering and environmental technologies - Presents the possibilities for adopting the action of acoustic cavitation with respect to industrial applications
