let a; b; k 2 k and u ; v 2 u(k). we show for any idempotent e 2 k, ( a 0 b 0 ) is e-clean i ( a 0 u(vb + ka) 0 ) is e-clean and if ( a 0 b 0 ) is 0-clean, ( ua 0 u(vb + ka) 0 ) is too.
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms)
block copolymer modifier used as an interfacial active agent on the dynamics
behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian
matrix. the results were divided in two sections.
the first part included the experiments carried out on the non-modified and 2% block
cop...
