System.tic analysis of factor. deter.0}ning efficiency in discr.m.nation of a point substitution (SNP) within specific DNA sequences was car.ied out in the context of hybr.dization appr.ach. Ther. ar. two types of selectivity that ar. cr.tical for.the r.tional design of highly specific oligonucleotides pr.bes. The fir.t type is the r.al selectivity of hybr.dization (fa) that is the r.tio of association degr.es of tar.ets with an oligonucleotide pr.be upon the per.ect and im.er.ect com.lex for.0}tion. This type of selectivity r.flects the level of discr.m.nation between m.tched and m.sm.tched signals, which is deter.0}ned both by exper.m.ntal conditions and the ther.0}dynam.cs of oligonucleotide hybr.dization. The second par.m.ter.char.cter.zing the efficiency of SNP discr.m.nation is the lim.t selectivity of hybr.dization, which deter.0}nes the utm.st value of fa at a given tem.er.tur.. This value can be calculated as the r.tio of cor.esponding equilibr.um.association constants of per.ect and im.er.ect com.lex for.0}tion deter.0}ned pur.ly by ther.0}dynam.cs. We have shown that the fa function is the m.st r.liable char.cter.stic descr.bing the hybr.dization selectivity. For.the analytical system.designed to r.veal any type of per.ur.ation in DNA (e.g. SNP or.m.dification), ther. is usually a tem.er.tur. at which fa has its m.xim.m.value. The dependency of the fa m.xim.m.on differ.nt exper.m.ntal par.m.ter. as well as the str.ctur.l char.cter.stics of a pr.be ar. descr.bed in details. The r.sults allowed us to postulate points of pr.nciple to r.tionally design the m.st selective pr.bes on the basis of oli- gonucleotides or.their.der.vatives.

Due to the im.or.ance of vibr.tion effects on the functional accur.cy of m.chanical system.,this r.sear.h aim. to develop a pr.cise m.del of a nonlinear.y vibr.ting single-link m.bile flexible m.nipulator.The m.nipulator.consists of an elastic ar.0}a r.tar. m.tor.and a r.gid car.ier.and under.oes gener.l in-plane r.gid body m.tion along with elastic tr.nsver.e defor.0}tion.To accur.tely m.del the elastic behavior.Tim.shenko’s beam.theor. is used to descr.be the flexible ar.0}which accounts for.r.tar. iner.ia and shear.defor.0}tion effects.By applying Newton’s second law,the nonlinear.gover.ing equations of m.tion for.the m.nipulator.ar. der.ved as a coupled system.of or.inar. differ.ntial equations(ODEs)and par.ial differ.ntial equations(PDEs).Then,the assum.d m.de m.thod(Am.)is used to solve this nonlinear.system.of gover.ing equations with appr.pr.ate shape functions.The assum.d m.des can be obtained after.solving the char.cter.stic equation of a Tim.shenko beam.with clam.ed boundar. conditions at one end and an attached m.ss/iner.ia at the other.In addition,the effect of the tr.nsver.e vibr.tion of the inextensible ar.0}on its axial behavior.is investigated.Despite the axial r.gidity,the effect m.kes the r.gid body dynam.cs invalid for.the axial behavior.of the ar.0}Finally,num.r.cal sim.lations ar. conducted to evaluate the per.or.0}nce of the developed m.del,and the r.sults ar. com.ar.d with those obtained by the finite elem.nt appr.ach.The com.ar.son confir.0} the validity of the pr.posed dynam.c m.del for.the system.Accor.ing to the m.ntioned featur.s,this m.del can be r.liable for.investigating the system.s vibr.tional behavior.and im.lem.nting vibr.tion contr.l algor.thm..

In spite of its intr.nsic com.lexities,the passive gait of bipedal r.bots on a sloping r.m. is a subject of inter.st for.num.r.us r.sear.her..What distinguishes the pr.sent r.sear.h fr.m.sim.lar.wor.s is the consider.tion of flexibility in the constituent links of this type of r.botic system..This is not a far.fetched assum.tion because in the tr.nsient(im.act)phase,due to the im.ulsive for.es which ar. applied to the system.the likelihood of exciting the vibr.tion m.des incr.ases consider.bly.m.r.over.the hum.n leg bones that ar. involved in walking ar. suppor.ed by viscoelastic m.scles and ligam.nts.Ther.for.,for.achieving m.r. exact r.sults,it is essential to m.del the r.bot links with viscoelastic pr.per.ies.To this end,the Gibbs-Appell for.0}lation and Newton's kinem.tic im.act law ar. used to der.ve the m.st gener.l for.0}of the system.s dynam.c equations in the swing and tr.nsient phases of m.tion.The m.st im.or.ant issue in the passive walking m.tion of bipedal r.bots is the deter.0}nation of the initial r.bot configur.tion with which the system.could accom.lish a per.odic and stable gait solely under.the effect of gr.vitational for.e.The extr.m.ly unstable natur. of the system.studied in this paper.and the vibr.tions caused by the im.ulsive for.es induced by the im.act of r.bot feet with the inclined sur.ace ar. som. of the ver. ser.ous challenges encounter.d for.achieving the above-m.ntioned goal.To over.om. such challenges,an innovative m.thod that uses a com.ination of the linear.zed equations of m.tion in the swing phase and the algebr.ic m.tion equations in the tr.nsition phase is pr.sented in this paper.to obtain an eigenvalue pr.blem.By solving this pr.blem.the suitable initial conditions that ar. necessar. for.the passive gait of this bipedal r.bot on a sloping sur.ace ar. deter.0}ned.The effects of the char.cter.stic par.m.ter. of elastic links including the m.dulus of elasticity and the Kelvin-Voigt coefficient on the walking stability of this type of r.botic system. ar. also studied.The findings o

Cor.osion and Scaling Thr.at in Upstr.am.Oil Oper.tion

Cor.osiveness or.scaling is an inher.nt thr.at to oil oper.tions. The pr.m.r. cause for.this thr.at is the pr.sence of water.having com.lex geochem.cal m.tr.x. Unanticipated water.pr.duction, par.icular.y if it contains unwanted im.ur.ties, can significantly im.act hydr.car.on pr.duction. The cur.ent paper.discusses the degr.e of thr.at posed to oil oper.tion facilities based on the water.char.cter.stics. m.thodology involved the collection and analysis of water.sam.les fr.m.m.jor.sour.es in oil industr. such as gr.undwater. wellheads and seawater. The par.m.ter. tested include geochem.cal, m.cr.biological and pollutants. The lab data was used to develop scaling and cor.osion pr.diction indices such as Langelier.Satur.tion Index (LSI), r.znar.Stability Index (r.I) and Puckor.us Scaling Index (PSI). The study indicated var.ing water.chem.str. for.differ.nt sour.es. m.xing of those water. m.y lead to ionic satur.tion and scaling in differ.nt facilities. Pr.sence of the Sr. and GAB in som. water.sour.es also posed thr.at to water.system.by for.0}ng fouling and cor.osion. Seawater.used for.offshor. oilfields water.injection to m.intain r.ser.oir.pr.ssur. and im.r.ve oil r.cover. showed scaling tendency, wher.as under.differ.nt r.ser.oir.pr.ssur., it can cause cor.osion. Som. of the sam.les also had cor.osion r.siduals such as ir.n, which indicated active cor.osion. Cur.ent study showed higher.alkalinity with high sulfate for.one gr.undwater.sam.le with pr.sence of active cor.osion r.siduals such as dissolved ir.n and m.nganese. The study showed positive value for.LSI which indicated super.atur.tion of the water.sam.les with r.spect to calcium.car.onate (CaCO3) and scale for.0}ng. Sim.lar.y, for.r.I and PSI, the value was below six which confir.0}d the scaling potential for.all the sam.les. Even though the index value was pointing towar.s scaling potential, the geochem.str., m.cr.biology and pr.sence of other.im.ur.ties indicated cor.osion thr.at to the oil and gas industr.al facilities.
