The dominant perspective in discussions of labor and environmental standards and globalization is that of North-South competition and its impact on Northern standards. This paper presents an alternative perspective, that of South-South competition to export to the North, and its impact on Southern standards. It develops a simple model of Southern competition on standards, which can begin to pro...

the polymeric and non-polymeric petrochemical wastes are environmentally unfavorable materials. we have to found a way to reuse these wastes in a safe manner. in styrene-butadiene rubber (sbr) production plant two major wastes are produced one is a fine rubber powder and the other is recycled n-methyl pyrrolidone (nmp). in high-density polyethylene (hdpe) production plant also a low molecular w...

To understand the seismic damage characteristics of bottom frame-wall buildings and to study their seismic performance, the seismic damage outcomes of  bottom frame-wall structures in Du jiang weir by the Wen chuan earthquake on May 12,2008, China were field observed and studied. The assesment of the seismic damage to the bottom frame-wall masonry in Du jiang weir urban showed that the damage t...

this study was aimed to evaluate the effects of diets containing some hot and coldtemperament herb seeds according to iranian traditional medicine (itm) on some metabolicparameters in acute (24 h) and sub-acute (7 day) experiments that were performed on rats. foreach experiment, effects of diets containing 10% herb seeds in category of hot (anise, fennel,ajowan) and cold (cucumber, watermelon, ...

Previous studies carried out with Pecten maximus (Bivalvia: Pectinidae) juveniles in the Bay of Brest have demonstrated that diatom and, more obviously, toxic dinoflagellate blooms could have a negative effect on the daily growth rate. The aim of this study was to characterize the daily shell growth from early 1998 to late spring 1999 with a careful qualitative and quantitative description of t...

The effects of bottom trawling on benthic invertebrates include reductions of biomass, diversity and body size. These changes may negatively affect prey availability for demersal fishes, potentially leading to reduced food intake, body condition and yield of fishes in chronically trawled areas. Here, the effect of trawling on the prey availability and diet of two commercially important flatfish...
