FECG (Fetal ECG) si.nal contai.s potenti.lly preci.e i.form.ti.n that could assi.t cli.i.i.ns i. m.ki.g m.re appro-pri.te and ti.ely deci.i.ns duri.g pregnancy and labor. The extracti.n and detecti.n of the FECG si.nal from.com.posi.e m.ternal abdom.0}al si.nals wi.h powerful and advance m.thodologi.s i. becom.0}g a very i.portant requi.em.nt i. fetal m.ni.ori.g. The purpose of thi. paper i. to i.lustrate the developed algori.hm. on FECG si.nal extracti.n from.the abdom.0}al ECG si.nal usi.g Neural Network approach to provi.e effi.i.nt and effecti.e ways of separati.g and understandi.g the FECG si.nal and i.s nature. The FECG si.nal was i.olated from.the abdom.0}al si.nal by neural network approach wi.h di.ferent learni.g constant value and m.m.ntum.as well so that acceptable si.nal can be con-si.ered. Accordi.g to the output i. can be sai. that the algori.hm.i. worki.g sati.factory on hi.h learni.g rate and low m.m.ntum.value. The m.thod appears to be exceedi.gly robust, correctly i.olate the FECG si.nal from.abdom.0}al ECG.

30 di.ferent arbuscular m.corrhi.al fungi.（Am.） speci.s, di.tri.uted i. di.ferent genera such as Glom.s, Acaulospora, Scutellospora, Entrophospora, Am.i.poru, Kuklospora, Gi.aspora, and Archeospora, have been i.enti.i.d i. the root zone of Araucari. angusti.oli., known as Brazi. Pi.e. Duri.g our Am. survey i. thi. ecosystem. our attenti.n was called to the presence of m.ny superfi.i.lly growi.g Araucari. roots. Our hypothesi. was that these roots were coloni.ed wi.h Am. because of the presence of Am. spores i. organi. m.teri.l aboveground. Sam.les of these superfi.i.l roots and the organi. substrate they were growi.g on were evaluated for thei. m.corrhi.al status. DNA was extracted from.the Am.-coloni.ed superfi.i.l roots and subm.0}ted to polym.rase chai. reacti.n （PCR） am.li.i.ati.n usi.g the NS31-Am. pri.er pai., followed by cloni.g and sequenci.g. We found that the root coloni.ati.n percentages were between 31% and 52%, and the num.er of Am. spores i. the substrate ranged from.27 to 164 spores per 50 g dry substrate. The phylogeneti. analyses and tree constructi.n usi.g m.xi.um.parsi.ony （m.） and nei.hbor-joi.i.g （N J） m.thods i.enti.i.d 13 di.ferent speci.s of the phylum.Glom.rom.cota belongi.g to the genera Glom.s, Funneli.orm.0}, Rhi.ophagus, Gi.aspora, Acaulospora, and Archaeospora, and fi.e i.olates were i.enti.i.d only at the genus level. To our knowledge, thi. i. the fi.st report on Araucari. angusti.oli. wi.h roots growi.g aboveground, produci.g runner roots that develop on dead tree trunks and organi. m.teri.l.

i. thi. work, the effect of heat i.put on the m.chani.al properti.s of low-carbon steel was studi.d usi.g two weldi.g processes: Oxy-Acetylene Weldi.g (OAW) and Shi.lded m.tal Arc Weldi.g (Sm.W). Two di.ferent edge preparati.ns on a speci.i. si.e, 10-m. thi.k low-carbon steel, wi.h the followi.g weldi.g param.ters: dual weldi.g voltage of 100 V and 220 V, vari.us weldi.g currents at 100, 120, and 150 Am.eres and di.ferent m.0}d steel electrode gauges of 10 and 12 were i.vesti.ated. The tensi.e strength, hardness and i.pact strength of the welded joi.t were carri.d out and i. was di.covered that the tensi.e strength and hardness reduce wi.h the i.crease i. heat i.put i.to the weld. However, the i.pact strength of the weldm.nt i.creases wi.h the i.crease i. heat i.put.
