Correlations that allow determination of gas film mass transfer coefficients (kGat , kGaw) and liquid film mass transfer coefficients (kLaw) for packing materials used in biofilters and biotrickling filters for air pollution control are presented. Lava rock, polyurethane foam cubes (PUF), Pall rings, porous ceramic beads, porous ceramic Raschig rings, and various compost–woodchips mixtures were...

Composting of deer carcasses was effective in reducing pathogen levels, decomposing the carcasses and producing a useable end product after 12 months. The composting process used in this project involved enveloping the carcasses of road-killed deer in woodchips and allowing those pues with natural air circulation to sit undisturbed. Temperatures were measured and samples from the piles were ana...

Stakeholders perception of biomass chain – in terms of socio-economic and environmental sustainability – is an important topic in territorial planning. On this subject rational and emotional aspects of perception have to be taken into account in participative approaches. The innovation of the present research was the application of semantic differential approach for the evaluation of bioenergy ...

This paper considers prediction of slip from a distance for wheeled ground robots using visual information as input. Large amounts of slippage which can occur on certain surfaces, such as sandy slopes, will negatively affect rover mobility. Therefore, obtaining information about slip before entering a particular terrain can be very useful for better planning and avoiding terrains with large sli...

[continued on page 2] The South Carolina Department of Health and Environmental Control (SCDHEC) recently completed a field-scale pilot study on the use of an in-situ sulfate-reducing bioreactor/ permeable reactive barrier (SRBR/PRB) to address metals contamination in ground water at the Stoller Chemical Site in Jericho, SC. The SRBR/PRB contains common biomaterial such as coastal hay, woodchip...

This paper presents an approach for slip prediction from a distance for wheeled ground robots using visual information as input. Large amounts of slippage which can occur on certain surfaces, such as sandy slopes, will negatively affect rover mobility. Therefore, obtaining information about slip before entering such terrain can be very useful for better planning and avoiding these areas. To add...
