Among the many environmental problems that offend and concern us perhaps none is as powerful and dramatic as water pollution. It is any undesirable change in physical, biological or chemical characteristics of water quality that adversely affects living organisms or makes water unsuitable for desirable use. Major sources that pollute water are domestic sewage and industrial effluents, acid rain etc. These are discharged into the rivers which in turn results in marine pollution.Marine pollution has been going on unnoticed for a long time by the ....etc

MExE provides a standardized execution environment within the UE, and enables the negotiation of capabilities with the MExE service provider. This paper describes the types of service that can typically be delivered using MExE and the architecture of the MExE environment. It then goes on to discuss how MExE services may be accessed such as remote service access or application download. Finally the concepts of MExE and UE classmarks are discussed along with an overview of MExE Classmarks 1, 2 and 3. ....etc

Driving and the Built Environment: Effects of Compact Development on Motorized Travel, Energy Use, and CO2 Emissions examines the relationship between land development patterns and vehicle miles traveled (VMT) in the United States to assess whether petroleum use, and by extension greenhouse gas (GHG) emissions, could be reduced by changes in the design of development patterns. The report estimates the contributions that changes in residential and mixed-use development patterns and transit investments could make in reducing VMT by 2030 and 20 ....etc

Knowledge of the complex molecular structures of living cells is being accumulated at a tremendous rate. Key technologies enabling this success have been, high performance computing and powerful molecular graphics applications, but the technology is beginning to seriously lag behind challenges posed by the size and number of new structures and by the emerging opportunities in drug design and genetic engineering. A visual computing environment is being developed which permits interactive modeling of biopolymers by linking a 3D molecular graphics ....etc

Dynamic Load Balancing and Job Replication in a Global-Scale Grid Environment: A Comparison
Abstract
Global-scale grids provide a massive source of processing power, providing the means to support processor intensive parallel applications. The strong burstiness and unpredictability of the available processing and network resources raise the strong need to make applications robust against the dynamics of grid environments. The two main techniques that are most suitable to cope with the dynamic nature of the grid are Dynamic Load Balancing ....etc

The environmental impacts of dams have come under renewed examination in recent years.

Dam proponents have historically understood that dams largely improve the status of water-related energy and environmental issues by, for example, producing hydroelectric power and increasing the water supply for irrigation. Recently however, the negative impacts of dams have come increasingly into focus. Discussion over whether dam projects are ultimately beneficial or detrimental--to both the environment and surrounding human populations--has emerged wi ....etc
