Human exposure to polycyclic aromatic hydrocarbons (PAHs) and organophosphorus pesticides (OPPs) by dermal route is a continuing concern in environmental occupational toxicology. Diverse authors have measured vitro the absorption flux permeability coefficient (kP) of those compounds delivered on skin surface using volatile solvents. However, there isn’t harmonized method obtain kP when test sub...

Selfand binary Maxwell-Stefan diffusion coefficients were determined by equilibrium molecular dynamics simulations with the Green-Kubo method. This study covers selfdiffusion coefficients at liquid states for eight pure fluids, i.e. F2, N2, CO2, CS2, C2H6, C2H4, C2H2 and SF6 as well as Maxwell-Stefan diffusion coefficients for three binary mixtures N2+CO2, N2+C2H6 and CO2+C2H6. The fluids were ...

current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
