A novel onset based optimization method is proposed to convert a Fixed Polarity Reed-Muller (FPRM) function to a compact Multi-level Mixed Polarity Reed-Muller (MMPRM) forms. Onset table is introduced to represent an FPRM function. By operating on the onset table to extract common variables, its compact MMPRM is obtained. The spatial complexity of the proposed algorithm is O(M×n) (M is onset si...

• Variation in endophytic fungal diversity closely associated with roots, stems and leaves of common reed (Phragmites australis) is reported here at sites with different oxygen conditions. • Fungi isolated from surface-sterilized reed tissue were identified and characterized by morphological and molecular methods including internal transcribed spacer (ITS) sequence analysis from two dry and two...

industrial wastewaters are of the major sources of heavy metal pollution in the environment. in the middle east, gas and oil industry is the major source of heavy metal pollution and releases significant amounts of metals into the terrestrial and aquatic environment. in this research the capability of the common reed ( phragmitis australis ) in absorbing heavy metals cd, pb and v from the waste...

the concentration of three metals, zinc, copper and chromium in roots, rhizomes, stems and leaves of phragmites australis (common reed) and scirpus maritimus, and in the corresponding sediment and water samples from lia industrial area (qazvin, iran) were investigated to determine difference in distribution among plant organs. data were collected at during 1-year period. results showed that met...
