In many spe.ie., agonistic inte.actions re.ult in social re.ationships that are.stable.ove. time. In Syrian hamste.s, two unfamiliar male. that are.place. toge.he. will fight vigorously and a cle.r winne./lose. re.ationship is usually e.tablishe.. In subse.ue.t inte.actions, the.lose. will fle. soon afte. de.e.ting the.familiar winne.. He.e.we.te.te. the.hypothe.is that losing a fight with a conspe.ific will affe.t future.agonistic inte.actions not only toward that individual （i.e., the.familiar winne.） but also toward unfamiliar conspe.ifics. To te.t this hypothe.is we.paire. two Syrian hamste. male. in thre. trials on one.day in which the.lose. had tile.opportunity to e.cape.the.winne.. The.ne.t day the.lose. was paire. with an unfarniliar male. also for thre. trials. If he.lost again, he.was te.te. on a third day with a third unfamiliar male. Subje.ts we.e.those.male. that we.e.lose.s on all thre. days. The.late.cy to e.cape.on the.first trial on Days 2 and 3 was significantly shorte. than on the.first trial on Day l, indicating that losing against the.first male.affe.te. the.re.ponse.toward unfamiliar male.. Howe.e., the.late.cy to e.cape.on the.first trial on Days 2 and 3 was significantly longe. than that on the.third trial on the.pre.e.ing day, indicating that a lose. tre.ts unfamiliar male. diffe.e.tly than a familiar winne.. The.e.re.ults sugge.t that a de.e.t during an inte.action with one.male.affe.ts late. agonistic be.avior towards othe., unfamiliar male. [Curre.t Zoology 57 （4）： 449-452, 2011].

An analytical e.pre.sion is pre.e.te. for the.susce.tibility of liquid cast iron to solidify according to the.Fe.C-X me.astable.syste. （also known as the.chilling te.de.cy of cast iron, CT）. The.analysis incorporate. the.nucle.tion and growth proce.se. associate. with the.e.te.tic transformation. The.CT is re.ate. to the.physicoche.ical state.of the.liquid, the.e.te.tic ce.ls in the.flake.graphite. and the.numbe. of nodule. in nodular cast iron. In particular, the.CT can be.re.ate. to the.critical wall thickne.s, Scr, or the.chill width, Wcr, in we.ge.shape. castings. Finally, this work se.ve. as a guide.for unde.standing the.e.fe.t of te.hnical factors such as the.me.t che.istry, the.sphe.oidizing and inoculation practice. and the.holding time.and te.pe.ature.on the.re.ultant CT and chill of the.cast iron. The.re.ical calculations of Sc, and Wc, compare.we.l with e.pe.ime.tal data for flake.graphite.and nodular cast iron.

In the.pre.e.t work, an alte.native.nume.ical me.hodology is de.e.ope. for a fast and e.fe.tive.simulation and analysis of the.comple. flow and e.e.gy conve.sion in Pe.ton impulse.hydro turbine.. The.algorithm is base. on the.lagrangian approach and the.unste.dy fre.-surface.flow during the.je.-bucke. inte.action is simulate. by tracking the.traje.torie. of re.re.e.tative.fluid particle. at ve.y low compute. cost. Mode.n re.re.sion tools are.imple.e.te. in a ne. parame.e.ization te.hnique.of the.inne. bucke. surface. Ke.-fe.ture.of the.mode. is the.introduction of additional te.ms into the.particle.motion e.uations to account for various hydraulic losse. and the.flow spre.ding, which are.re.ulate. and e.aluate. with the.aid of e.pe.ime.tal data in a laboratory Pe.ton turbine. The.mode. is applie. to study the.je.-runne. inte.action in various ope.ation conditions and the. to pe.form nume.ical de.ign optimization of the.bucke. shape. using a stochastic optimize. base. on e.olutionary algorithms. The.obtaine. optimum runne. attains re.arkably highe. hydraulic e.ficie.cy in the.e.tire.load range. Finally, a ne. small Pe.ton turbine.（150 kW） is de.igne., manufacture. and te.te. in the.laboratory, and its pe.formance.and e.ficie.cy ve.ify the.mode. pre.ictions.
