The observation of THz regime transmission resonances in an InGaAs/InP high electron mobility transistor (HEMT) can be attributed to excitation of plasmons in its two-dimensional electron gas (2DEG). Properties of grating-based, gatevoltage tunable resonances are shown to be adequately modeled using commercial finite element method (FEM) software when the HEMT layer structure, gate geometry and...
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...
Objectives: Social participation is an important aspect of health in ageing. It is also a part of life and a key element in function that improves physical and psychological health in the elderly. Using assistive mobility devices may influence social participation in this population. Current study aimed to compare social participation in older adults who use assistive mobility de...

Nitrate (NO3?)-polluted groundwater treatment by enhanced denitrification is becoming increasingly important due to rising NO3? concentrations and decreasing degradation capacities in aquifers. Besides evaluating the efficacy of substrates added trigger denitrification, secondary reactions must be closely monitored. Biodenitrification applied organic carbon (Corg) can lead considerable changes ...
