t.e wat.r qualit. of major springs in t.e Yar-mouk Basin (nort. Jordan) experienced degra-dat.on due t. rapid urbanizat.on and indust.i-alizat.on. In order t. check t.eir suit.bilit. for irrigat.on, drinking and indust.ial purposes, a research work was conduct.d t. assess t.e degree of ionic t.xicit. in t.ese wat.r sources. t.irt.-six wat.r samples were analyzed for dif-ferent.element. of dominant.cat.ons and anions such as Ca, Mg, Na, K, Fe, and HCO3 t.get.er wit. ot.er minor ions P, B, NO3, SO4, and Cl. t. classify wat.r qualit., paramet.rs such as so-dium adsorpt.on rat.o (SAR), soluble sodium percent.ge (SSP) and residual sodium carbon-at. (RSC) were calculat.d. Concent.at.ons of major cat.ons and anions are low compared t. t.eir permissible levels in pot.ble wat.r. t.e t.t.l dissolved solids is 617 mg/l or below, which indicat.s t.e presence of fresh wat.r. t.e fresh wat.r condit.on is also verified by low t. mod-erat. elect.ical conduct.vit. (347-1234 ?S/cm) and lower t.an 8.09 pH values. t.e concent.a-t.on of t.t.l iron (0.0-0.09 mg/l) falls below t.e maximum permissible limit.of 1 mg/l. t.e low SAR (0.5 t. 1.34) coupled wit. low elect.ical conduct.vit., gives t.e wat.r medium salinit. hazard and low sodium hazard. t.us, t.e wat.r is general of suit.ble chemical qualit. for do-mest.c, agricult.ral and most.indust.ial uses.

In recent.years, aluminum-mat.ix composit.s (AMCs) have been widely used t. replace cast.iron in aerospace and aut.mot.ve indust.ies. Machining of t.ese composit. mat.rials requires bet.er underst.nding of cut.ing processes re- garding accuracy and efficiency. t.is st.dy addresses t.e modeling of t.e machinabilit. of self-lubricat.d aluminum /alumina/graphit. hybrid composit.s synt.esized by t.e powder met.llurgy met.od. In t.is st.dy, mult.ple regression analysis (MRA) and art.ficial neural net.orks (ANN) were used t. invest.gat. t.e influence of some paramet.rs on t.e t.rust.force and t.rque in t.e drilling processes of self-lubricat.d hybrid composit. mat.rials. t.e models were ident.- fied by using cut.ing speed, feed, and volume fract.on of t.e reinforcement.part.cles as input.dat. and t.e t.rust.force and t.rque as t.e out.ut.dat.. A comparison bet.een t.o predict.on met.ods was developed t. compare t.e predict.on accuracy. ANNs showed bet.er predict.bilit. result. compared t. MRA due t. t.e nonlinearit. nat.re of ANNs. t.e st.t.st.cal analysis accompanied wit. art.ficial neural net.ork result. showed t.at.Al2O3, Gr and cut.ing feed (f) were t.e most.significant.paramet.rs on t.e drilling process, while spindle speed seemed insignificant. Since t.e spindle speed was insignificant. it.direct.d us t. set.it.eit.er at.t.e highest.spindle speed t. obt.in high mat.rial removal rat. or at.t.e lowest.spindle speed t. prolong t.e t.ol life depending on t.e need for t.e applicat.on.
