Transgene silencing has been shown to be associated with strong promoters, but it is not known whether the propensity for silencing is caused by the level of transcription, or some other property of the promoter. If transcriptional activity fosters silencing, then transgenes with inducible promoters may be less susceptible to silencing. To test this idea, a doxycycline-inducible luciferase tran...

attachment of children to their parents and their separation are two important growth processes which are summoned up in teens again and become more important. the present research tends to find out either the processes of attachment and separation among girls and boys take place in different ways or gender can affect the relationship between these two processes. to this end 300 students of the...

in this research, the effect of bubble surface area flux, sb, and particle size on flotation rate constant, k, of pyrite (fes2) particles was studied using bubble-particle interactions. the bubble-particle collision, attachment and detachment efficiencies were calculated under different flow regimes. the k increased with increase in the collision efficiency and decrease in the detachment effici...
