Echinacea purpurea (L.) is one of the important medicinal plant species. To obtain the tetraploid plants of Echinacea purpurea with improved medicinal qualities, the root tips of two true leaves seedlings were imbibed in 0.25 % (w/v) colchicine solution for 24, 48, 72, 96 and 168 h. The ploidy level of plants was determined by chromosome counting of root(More)
The treatment of municipal landfill's leachate is considered as one of the most significant environmental issues. In this study a laboratory experiment was conducted through land treatment, achieving an efficient and economical method by using Vetiver plant. Moreover, the effects of land treatment of leachate of municipal landfills on the natural reduction(More)
This study presents a new approach—preprocessing for reaching the stationary chain in time series—to unravel the interpolating problem of artificial neural networks (ANN) for long-term prediction of solid waste generation (SWG). To evaluate the accuracy of the prediction by ANN, comparison between the results of the multivariate regression model and ANN is(More)
Despite the broadening range of available treatments, the response of multiple sclerosis patients to disease-modifying therapies remains quite heterogeneous, thus a scheme is required in order to flag individuals achieving a suboptimal treatment response, so that they may switch to a different, possibly more effective disease-modifying therapy. There are(More)
