the mass transfer performance of a pulsed disc and doughnut column for extraction of samarium and gadolinium from aqueous nitrate solution with d2ehpa was investigated. the effects of operating parameters such as pulsation intensity, continuous and dispersed phase velocities on column performance were investigated. the axial dispersion model was used to obtain the overall mass transfer coeffici...

using a new numerical model, the pump-to-signal relative intensity noise (rin) transfer in singlepumpfiber optical parametric amplifiers for low modulation frequencies is investigated. the model includesfiber loss, pump depletion, as well as the gain saturation, and therefore, it can describe the practicalcircumstances associated with various applications of fiber optical parametric amplifiers....

In an effort to expand the disciplinary discussions on transfer in L2 writing and because most studies have focused on transfer as reuse and not as an adequate adaptation of writing knowledge in new contexts, the present study as the first of its kind aimed to explore the issue of adaptive transfer in an English for General Academic Purposes (EGAP) writing course. The study thus focused on type...
