Environmental Issues Associated with Crematoria: A Review
… practitioners and the general public about toxic emissions from crematoria as well as introduce sustainable practices to offset toxic emissions. Using publicly available data from four crematoria around the world, this study examines various factors associated with emissions including …

Entropy-stable hybridized discontinuous Galerkin methods for large-eddy simulation of transitional and turbulent flows
… designs, and further reduce fuel consumption and toxic emissions. Large-eddy simulation (LES) is currently the most promising simulation technique to accurately predict transitional and turbulent flows. LES, however, remains computationally expensive and often suffers from accuracy and robustness …

An analysis of hybrid-electric vehicles as the car of the future
… vehicle that can lower fuel usage and toxic emissions. We explore this environmentally responsible claim through four spectrums of interest: the consumer, the automaker, the government, and the environmentalist. After determining the different parameters that affect HEV integration, we …

Do improvements in environmental performance lead to job loss?
… performance. The facility could reduce its emissions of toxic chemicals by preventing pollution at the beginning of the process, controlling pollution by recycling or treating chemicals, or controlling pollution using end of pipe techniques. Furthermore, these responses can affect employment …

The effectiveness of the voluntary 33/50 program in inducing adoption of pollution prevention techniques and toxic release reduction
… information on program participation, toxic emissions and P2 adoption for more than 7000 facilities that were eligible for the program over the period of 1988-1995. We find that program participants had 14.8% to 23.7% higher rate of reduction in 33/50 releases than non-participants, …

Synthesis of nanostructured materials in deep eutectic solvents
… eutectic solvents (DES), a new generation of non-toxic, eco-friendly and biodegradable solvents discovered in 2001 consist of a variety of cations and anions. These new sub-category of ionic liquids present interesting properties due to the hydrogen bonding between their components and are being …

Atmospheric volatile organic compound measurements: Distributions and effects on air quality in coastal marine, rural and remote continental environments
… indicate that 2-stroke snowmobile engine emissions furnish large quantities of air toxics to the YNP air shed. Air toxics, which are major components of 2stroke engine exhaust, show large enhancements between the high traffic and low traffic sampling periods. Evaluation of the …
