Compost Biofilters for Protection of Environmentally Sensitive Areas Receiving Roadway Runoff

Protection of ‘sensitive’ receiving sites

The level of interference caused by distributed sources of this type is analysed for a range of reception and propagation scenarios. In the first instance it is assumed that these distributed interference sources arise from the use of PLT. However, with the appropriate change in parameters the analysis would also be applicable to other types of communication systems, such as those using existin...

Do Consumers of Environmentally Friendly Farming Products in Downstream Areas Have a WTP for Water Quality Protection in Upstream Areas?

In South Korea, the Soyang Lake is an important source of drinking water to the metropolitan areas including Seoul. However, water quality problems in the Soyang Lake have still remained due to chemical contaminations attributed to conventional farming practices in the upstream areas. Based on a downstream consumer survey using a contingent valuation method, this study estimated the expected wi...

Environmentally Sensitive Protein Reagents*

The use of protein reagents which exhibit sensitivity to changes in molecular environment has provided a means of examining certain properties of enzymes during interaction with their substrates (1). The recently reported 2-hydroxy-5nitrobenzyl bromide provided one such reagent, the absorption spectrum of which showed sensitivity to environmental changes by virtue of the p-nitrophenolic groupin...

application of methodology for mapping environmentally sensitive areas (esas) to desertification in dry bed of hamoun wetland (iran)

several models have been developed to estimate land degradation rate and evaluate desertification severity. this study attempts to apply the medalus (mediterranean desertification and land use) model by considering existing conditions in the hamoun wetland, located in south-eastern iran. at first identification of the main factors affecting the desertification phenomenon was attempted, based on...
