Erosion and deposition of bottom sediments reflect a continual, dynamic adjustment between the fluid forces applied to a sediment bed and the condition of the bed itself. Erosion of fine and mixed sediment beds depends on their composition, their vertical structure, their disturbance/recovery history, and the biota that inhabit them. This paper presents a new onedimensional (1D), multi-layer se...

A genetic algorithm assisted minimum mean-square error (MMSE) multi-user detector (MUD) is proposed for a turbo-trellis-coded modulation-based space division multiple access aided orthogonal frequency division multiplexing system. The simulation results show that the system employing the concatenated MMSE-GA MUD was capable of achieving a similar performance to that attained by its optimum coun...

After around a hundred years of being without any record of occurrence of Paracobitis rhadinaea, a species of Nemacheiline loach, in Sistan basin, southeast of Iran, the year 2012 was the turning point of wild life in this area. Twenty-five specimens were caught from Chahnimeh Reservoir, a water body adjacent to the Hamoun Wetland in Sistan basin. Morphometric and meristic characteristics were ...

Aquatic animals play an important role in the energy flow and matter cycling in the wetland ecosystem. However, little is known about their effects on pollutant removal performance and microbial community in constructed wetlands. This work presents an initial attempt to investigate the effects of Misgurnus anguillicaudatus (loach) and Cipangopaludina cathayensis (snail) on nutrient removal perf...

OBJECTIVE The aim of this study was to reveal the efficacy of mud pack treatment in patients with knee osteoarthritis and to find the contribution of chemical factors to the build up of these effects. METHODS Sixty patients were randomly assigned to directly applied mud pack (study) group or to nylon-covered mud pack (control) group. Thirty patients in the study group had mud application 15 t...

In the MIMO-OFDM systems, the traditional methods of multi-user detection have some limitations in the rank-deficient scenarios, where the number of supported users exceeds the number of receiver antennas. The multiuser detection (MUD) based on the genetic simulated annealing algorithm (GSAA) is proposed for the rankdeficient problems in the multi-user MIMO-OFDM system. The simulation results s...
