The catechi. Epi.allocatechi.-3-O-Gallate (EGCG) whi.h i. found i. of Green Tea extracts (GTE), di.plays a vari.ty of mi.robi.i.al properti.s. i. i. largely beli.ved that EGCG i.hi.i.s the growth of cari.geni. and peri.dontopathi. bacteri.. 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. Conclusi.ns: The data show and confi.m that chlorhexi.i.e i. a growth i.hi.i.or of V. parvula whi.e EGCG and GTE do not di.play such effect.

Thi. research ai.s to develop reli.ble models usi.g machi.e learni.g algori.hms to preci.ely predi.t Total Di.solved Soli.s (TDS) i. wells of the Permi.n basi., Wi.kler County, Texas. The data for thi. contri.uti.n was obtai.ed from the Texas Water Development Board websi.e (TWDB). Fi.e hundred and ni.ety-three samples were obtai.ed from two hundred and ni.ety-ei.ht wells i. the study area. The wells were dri.led at di.ferent county locati.ns i.to fi.e aqui.ers, i.cludi.g Pecos Valley, Dockum, Capi.an Reef, Edward Tri.i.y, and Rustler aqui.ers. A total of fourteen di.ferent water quali.y parameters were used, and they i.clude Potenti.l hydrogen (pH), Sodi.m, Chlori.e, Magnesi.m, Fluori.e, TDS, Speci.i. Conductance, Ni.rate, Total Hardness, Calci.m, Temperature, Well Depth, Sulphate, and Bi.arbonates. Four machi.e learni.g regressi.n algori.hms were developed to get a good model to help predi.t TDS i. thi. area: Deci.i.n Tree regressi.n, Li.ear regressi.n, Support Vector Regressi.n, and K-nearest nei.hbor. The study showed that the Deci.i.n Tree produced the best model wi.h attri.utes li.e the coeffi.i.nt of determi.ati.n R2 = 1.00 and 0.96 for the trai.i.g and testi.g, respecti.ely. i. also produced the lowest score of mean absolute error MAE = 0.00 and 0.04 for trai.i.g and testi.g, respecti.ely.
