The assessment of the possibility using incinerated municipal waste, which is classified as non-hazardous, a priority European zero waste strategy. aim this work was to identify properties slag and ash develop simple, targeted way post-process waste. material analyzed by microscopic methods in terms composition internal structure. Gas water permeability tests were carried out. Slag texture obta...

background and purpose: the heavy metal pollution and its fractionations in the surface sediments of darreh-morad beyg river, hamedan city were monitored for cd, cr, cu, fe, ni, pb, and zn in 2014.   materials and methods: totally 30 surface sediment samples were taken from 10 stations with three replicates. the samples subjected to bulk digestion and chemical partitioning. the concentrations o...

the effect of temperature on the adsorption of heavy metals on not only natural bulk clay, but also for the individual phases that composed the bulk clay sample, was investigated. combined adsorption- sequential extraction analysis (casa) for pb, cu, zn and cd were conducted under various temperatures that ranged from 150c to 550c. as a result, it was found that heavy metals adsorption for b...

this study was carried out to 1. determine spatial variations of heavy metal deposition in agricultural soils of two rural communities (ouledbouaicha and tazakourte) of about 5790 ha in a mining area near marrakech city in morocco; 2. to assess the extent of metallic pollution generated by the mining activity and; 3. to identify the key mechanism responsible for this contamination and its relat...

biomedical datasets usually include a large number of features relative to the number of samples. however, some data dimensions may be less relevant or even irrelevant to the output class. selection of an optimal subset of features is critical, not only to reduce the processing cost but also to improve the classification results. to this end, this paper presents a hybrid method of filter and wr...
