  • Aquatic scientists have always been intrigued with concepts of scale. This interest perhaps stems from the nature of ßuid dynamics in oceans and lakes — energy cascades from spatial scales of kilometers down to viscous scales at centimeters or less. Turbulent processes affect not only an organism’s perception of, and response to, the physical environment, but also the interaction between species, both within and across trophic levels.

  • Dust is a ubiquitous feature of the cosmos, impinging directly or indirectly on most fields of modern astronomy. Dust grains composed of small (submicronsized) solid particles pervade interstellar space in the Milky Way and other galaxies: they occur in a wide variety of astrophysical environments, ranging from comets to giant molecular clouds, from circumstellar shells to galactic nuclei. The study of this phenomenon is a highly active and topical area of current research.

  • At low levels of development measured by per capita GDP, environment pollution will increase. As a country reaches a certain level of GDP, environmental pollution tends to decrease as income increases. The Environmental Kuznets Curve (EKC) basically describes the relationship between the concentrations of air pollution in the country relative to its gross national income per capita. It is stated that as a country starts to develop (as depicted by the increase of GNP/capita), air pollution level rises due to the increase in production of commodities.

  • Tritium, the heaviest and only radioactive isotope of hydrogen, is increasing in importance in energy and environmental considerations. This nuclide is widely distributed throughout man's environment because of its ubiquitous form as tritiated water and its persistence in the environment. This report considers and evaluates the available information on tritium in terms of its physical properties, production sources, physical transport, biological behavior, projected future production, waste management, and the long-term dose implications of tritium in the environment....

  • Grid computing architecture was defined to be a complete physical layer. Based on the grid computing architecture, we divided grid nodes into supervisor grid node and execute grid nod. The data transfer in network must be in secure. In this study, we propose the encryption and decryption algorithm in each grid node to keep information processing in security. We create user information database both in supervisor and execute grid nodes. We use them to verify user processing in system.

  • This volume covers the technologies that are applied to the treatment and purification of water. Those who are generally familiar with this field will immediately embrace the subject as a treatise on solid-liquid separations. However, the subject is much broader, in that the technologies discussed are not just restricted to pollution control hardware that rely only upon physical methods of treating and purifymg wastewaters.

  • An ecosystem is a group of animals and plants living in a specific region and interacting with one another and with their physical environment. Ecosystems include physical and chemical components, such as soils, water, and nutrients that support the organisms living there. These organisms may range from large animals to microscopic bacteria. Ecosystems also can be thought of as the interactions among all organisms in a given habitat; for instance, one species may serve as food for another. People are part of the ecosystems where they live and work.
