Society is increasingly concerned about the implications of manufactured products for the environment, public health, and future costs. How does a product affect global warming, smog, fossil fuel depletion, and human toxicity? How about its costs over time? Building for Environmental and Economic Sustainability (BEES) addresses these questions by measuring the life-cycle environmental and econo...
Divergence dating studies, which combine temporal data from the fossil record with branch length data from molecular phylogenetic trees, represent a rapidly expanding approach to understanding the history of life. National Evolutionary Synthesis Center hosted the first Fossil Calibrations Working Group (3-6 March, 2011, Durham, NC, USA), bringing together palaeontologists, molecular evolutionis...
Bioethanol has many environmental and practical benefits as a transportation fuel. It is one of the best alternatives to replace fossil fuels due its liquid nature, which similar gasoline diesel traditionally used in transportation. In addition, bioethanol production technology capacity for negative carbon emissions, vital solving current global warming dilemma. However, conventional takes plac...
Abstract Aquifers offer a reliable supply of high-quality water, making groundwater significant in arid and semi-arid regions. Climate change is predicted to result decrease rainfall an increase droughts. The prolonged drought severely devastated Iraq the main reason for ongoing consumption over last decade. In this study, stresses depletion potentials Dammam confined aquifer, which extended al...
The supply and the management of the energy are particularly at the centre of our daily concerns and represent a socio-economic priority. Indeed, while cars use fossil fuel as the main source of energy for over a century, the depletion of the oil reserves and the necessity to reduce the carbon dioxide emissions, stimulate the development of electric vehicles. Therefore, one of the main challeng...
Modern agriculture is heavily dependent on fossil resources. Both direct energy use for crop management and indirect energy use for fertilizers, pesticides and machinery production have contributed to the major increases in food production seen since the 1960s. However, the relationship between energy inputs and yields is not linear. Low-energy inputs can lead to lower yields and perversely to ...
Mining of coal (fossil fuel) resources in Enugu resulted groundwater pollution/depletion and left the mine site with potentials air pollution, loss landscape/aesthetic degradation soil contamination. Other Environmental impacts were extensive damage, alteration microbial communities affecting vegetation leading to destruction vast amounts land displacement dwellers. Reclamation is process resto...
With rapid world growth and changing consumer demands and attitudes, sustained economic and social development will depend upon a secure supply of raw-material inputs for manufacturing needs. Continued depletion of limited global natural resources supports the concept of supplying industrial production and energy needs through the use of renewable, or biobased, resources. The United States has ...
Carbon Capture and Storage is being actively developed for deployment in fossil fuel power stations in an attempt to reduce future emissions of CO2 due to concerns about climate change. The deployment of this technology will cause an inevitable reduction in the overall efficiency of any electricity generation plant leading to an increase in demand for the fossil fuels used to power the generati...
The increasing global need for energy coupled with the depletion of easily accessible, hence cheap, fossil fuel reserves, poses a serious threat to the human global economy in the near future [1]. Considering in addition the harmful ecological impact of conventional energy sources, it becomes obvious that development of clean alternative energy sources is a neces‐ sity [2, 3]. Best renewable en...
