Many.phenomena i. nature and technology.are associ.ted wi.h the fi.trati.n of suspensi.ns and colloi.s i. porous medi.. Two mai. ty.es of parti.le deposi.i.n,namely. cake fi.trati.n at the i.let and deep bed fi.trati.n throughout the enti.e porous medi.m, are studi.d by.di.ferent models. A uni.i.d approach for the transport and deposi.i.n of parti.les based on the deep bed fi.trati.n model i. proposed. A vari.ble suspensi.n flow rate, proporti.nal to the number of free pores at the i.let of the porous medi.m, i. consi.ered. To model cake fi.trati.n, thi. flow rate i. i.troduced i.to the mass balance equati.n of deep bed fi.trati.n. For the cake fi.trati.n wi.hout deposi. erosi.n,the suspensi.n flow rate decreases to zero, and the suspensi.n does not penetrate deep i.to the porous medi.m. i. the case of the cake fi.trati.n wi.h erosi.n, the suspensi.n flow rate i. nonzero, and the deposi. i. di.tri.uted throughout the enti.e porous medi.m.

The catechi.

Objecti.e: i. thi. paper we compared the i.hi.i.ory.acti.i.y.of EGCG and a commerci.l GTE on the growth of Vei.lonella parvula. Chlorhexi.i.e was used as posi.i.e control. Methodology. V. parvula ATCC 10790 and a cli.i.al i.olate obtai.ed from a peri.dontal di.ease pati.nt were cultured i. the presence of EGCG or a commerci.l GTE, and the measurements of bacteri.l growth i.hi.i.i.n were compared to the values obtai.ed wi.h 0.12 and 0.2% chlorhexi.i.e. Results: Chlorhexi.i.e i.hi.i.ed bacteri.l growth, however i. contrast to a previ.us report, nei.her EGCG nor the GTE showed any.effect on bacteri.l growth.
