Strategies for Decreasing the Unit Energy and Environmental Impact of Hall Heroult Cells

The limited fossil reserves, spiraling price and environmental impact due to usage of fossil fuels leads the world wide researchers’ interest in using alternative renewable and environment safe fuels that can meet the energy demand. Biodiesel is an emerging renewable alternative fuel to conventional diesel which can be produced from both edible and non-edible oils, animal fats, algae etc. The society is in dire need of using renewable fuels as an immediate control measure to mitigate the pollution level. In this work an attempt is made to review the requisite and access the capability of the biodiesel in improving the environmental degradation.

Central Africa remained botanically unknown to the outside world up to the end of the eighteenth century. This paper provides a historical account of plant explorations in the Luangwa Valley. The first plant specimens were collected in 1897 and the last serious botanical explorations were made in 1993. During this period there have been 58 plant collectors in the Luangwa Valley with peak activity recorded in the 1960s. In 1989 1,348 species of vascular plants were described in the Luangwa Valley. More botanical collecting is needed with a view to finding new plant taxa, and also to provide a satisfactory basis for applied disciplines such as ecology, phytogeography, conservation and environmental impact assessment.

Regulatory Commission

Natural gas is an increasingly vital U.S. energy source that is presently being tapped and transported across state and international boundaries. Controversy engulfs natural gas, from the hydraulic fracturing process used to liberate it from massive, gas-laden Appalachian shale deposits, to the permitting and construction of new interstate pipelines bringing it to markets. This case explores the controversy flowing from the proposed 256-mile-long interstate Nexus pipeline transecting northern Ohio, southeastern Michigan and terminating at the Dawn Hub in Ontario, Canada. As the lead agency regulating and permitting interstate pipelines, the Federal Energy Regulatory Commission is also tasked with mitigating environmental risks through the 1969 National Environmental Policy Act's Environmental Impact Statement process. Pipeline opponents assert that a captured federal agency ignores public and scientific input, inadequately addresses public health and safety risks, preempts local control, and wields eminent domain powers at the expense of landowners, cities, and everyone in the pipeline path. Proponents counter that pipelines are the safest means of transporting domestically abundant, cleaner burning, affordable gas to markets that will boost local and regional economies and serve the public good. Debates over what constitutes the public good are only one set in a long list of contentious issues including pipeline safety, proposed routes, property rights, public voice, and questions over the scientific and democratic validity of the Environmental Impact Statement process. The Nexus pipeline provides a sobering example that simple energy policy solutions and compromise are elusive—effectively fueling greater conflict as the natural gas industry booms.
