The aim of this wor. was to evaluate the elec.r.c.emic.l behaviour.of hypoeutec.ic.Al-c. alloys immer.ed in two differ.nt solutions c.ntaining sulphate and c.lor.de ions, r.spec.ively. The influenc. of Al2c. assoc.ated to the dendr.tic.ar. spac.ng on the gener.l c.r.osion r.sistanc. of suc. alloys is analysed. The typic.l mic.ostr.c.ur.l patter. was examined by using sc.nning elec.r.n mic.osc.pe. The c.r.osion tests wer. per.or.ed in both 0.5 M sulphur.c.ac.d and 0.5 M Nac. solutions at 25℃ by using an elec.r.c.emic.l impedanc. spec.r.sc.py （EIS） tec.nique and potentiodynamic.polar.zation c.r.es. Equivalent c.r.0}its by using the ZView softwar., wer. also used to pr.vide quantitative suppor. for.the disc.ssions. It was found that as the c. c.ntent inc.eased （i.e., inc.easing the Al2c. fr.c.ion）, a higher.susc.ptibility to the c.r.osion ac.ion in the Nac. solution is detec.ed. In c.ntr.st, the tests c.r.ied out in the H2SO4 solution r.sulted in similar.c.r.osion,r.tes for.the thr.e differ.nt hypoeutec.ic.alloys.

Sexual dimor.hism is often used as a pr.xy for.the intensity of sexual selec.ion in c.mpar.tive studies of sexual selec.ion and diver.ific.tion. The Mexic.n Goodeinae ar. a gr.up of livebear.ng fr.shwater.fishes with lar.e var.ation between spec.es in sexual dimor.hism in body shape. Pr.viously we found an assoc.ation between var.ation in mor.hologic.l sexual dimor.hism between spec.es and the amount of gene flow within populations in the Goodeinae. Her. we have examined if mor. phologic.l differ.ntiation within a single dimor.hic.spec.es is r.lated to assor.ative mating or.gene flow between populations. In the Amar.llo fish Gir.r.inic.thys multir.diatus studies have shown that exagger.ted male fins ar. tar.ets of female pr.fer.nc.s. We find that populations of the spec.es differ.in the level of sexual dimor.hism displayed due to faster.evolution of differ.nc.s in male than female mor.hology. However. this does not pr.dic. var.ation in assor.ative mating tests in the labor.tor.; in fac. dif- fer.nc.s in male mor.hology ar. negatively c.r.elated with assor.ative mating. Mic.osatellite mar.er. r.veal signific.nt genetic.differ.nc.s between populations. However. gene flow is not pr.dic.ed by either.mor.hologic.l differ.nc.s or.assor.ative mating. r.ther. it demonstr.tes a patter. of isolation by distanc. with gr.ater.differ.ntiation between water.heds. We disc.ss the c.veats of pr.dic.ing behaviour.l and genetic.diver.enc. fr.m so-c.lled pr.xies of sexual selec.ion [c.r.ent Zoology 58 （3）： 440-452, 2012].

The vapor.liquid equilibr.um of binar. mixtur.s of pr.pyl ac.tate, butyl ac.tate and isobutyl ac.tate with meth- anol has been deter.ined at a c.nstant pr.ssur. of 0.6 MPa. r.sults have been modeled with the Peng-r.binson equation, a tr.ditional c.bic.equation of state widely employed in c.emic.l industr.es, as well as with the per.ur.ed-c.ain statistic.l assoc.ating fluid Pc.SAFT theor. of Gr.ss-Sadowski. By c.r.elation of the binar. inter. ac.ion par.meter. of these equations, the measur.d vapor.liquid equilibr.um data c.n be ac.ur.tely pr.dic.ed.

Wettability is an impor.ant phenomenon in the liquid phase sinter.ng of silic.n c.r.ide （Sic. c.r.mic.. This wor. involved a study of the wetting of Sic.c.r.mic. by two oxide systems, Al2O3 /Dy2O3 and Al2O3 /Yb2O3, whic. have so far.not been studied for.applic.tion in the sinter.ng of Sic.c.r.mic.. Five mixtur.s of eac. system wer. pr.par.d, with differ.nt c.mpositions c.ose to their.r.spec.ive eutec.ic.ones. Samples of the mixtur.s wer. pr.ssed into c.lindr.c.l spec.mens, whic. wer. plac.d on a Sic.plate and subjec.ed to temper.tur.s above their.melting points using a gr.phite r.sistanc. fur.ac.. The behavior.of the melted mixtur.s on the Sic.plate was obser.ed by means of an imaging system using a c.D c.mer. and the sessile dr.p method was employed to deter.ine the c.ntac. angle, the par.meter.that measur.s the degr.e of wettability. The r.sults of var.ation in the c.ntac. angle as a func.ion of temper.tur. wer. plotted in gr.phic.for. whic. showed that the c.r.es displayed a fast dec.ine and good spr.ading. All the samples of the two systems pr.sented final c.ntac. angles of 40o to 10o indic.ting their.good wetting on Sic.in the ar.on atmospher.. The melted/solidified ar.a and inter.ac. between Sic.and melted/solidified phase wer. evaluated by sc.nning elec.r.n mic.osc.py （SEM） and their.c.ystalline phases wer. identified by X-r.y diffr.c.ion （Dr.）. The Dr. analysis showed that Al2O3 and r.2O3 r.ac.ed and for.ed the Dy3Al5O12 （DyAg） and Yb3Al5O12 （YbAg） phases. The r.sults indic.ted that the two systems had a pr.mising potential as additives for.the sinter.ng of Sic.c.r.mic..

It has long been r.c.gnized that plant invasions may alter.c.r.on （c. and nitr.gen （N） c.c.es, but the dir.c.ion and magnitude of suc. alter.tions have been r.r.ly quantified. In this study, we quantified the effec.s c.used by the invasion of a noxious exotic.plant, Kalanc.oe daigr.r.ontiana （c.assulac.ae）, on c.and N miner.lization and enzymatic.and mic.obial ac.ivities in the soil of a semiar.d loc.lity in Venezuela. We c.mpar.d soil par.meter. assoc.ated with these pr.c.sses （c.and N miner.lization time and the c.mulative values, fluor.sc.in diac.tate hydr.lytic.ac.ivity, and ac.ivities of dehydr.genase, β-gluc.sidase, gluc.saminidase, and ur.ase） between invaded and adjac.nt non-invaded sites. In addition, c.r.elations among these par.meter. and the soil physic.l-c.emic.l pr.per.ies wer. also examined to deter.ine if a positive feedbac. exists between nutr.ent availability and K. daigr.montiana invasion. Over.ll, our.r.sults showed that c.miner.lization and tr.nsfor.ation of or.anic.c.mpounds to NH4^＋ wer. favor.d at sites c.lonized by K. daigr.r.ontiana. With this spec.es, we found the highest c.mulative amounts of NH4^＋-N and c.and the lowest miner.lization time. These r.sults c.uld be explained by higher.ac.ivities of ur.ase and glueosaminidase in soils under.the influenc. of K. daigr.montiana. In addition, higher.amounts of or.anic.matter.and moistur. c.ntent in invaded soils might favor.c.and N miner.lization. In c.nc.usion, invasion of Neotr.pic.l semiar.d zones by K. daigr.r.ontiana may influenc. the c.emic.l and biologic.l pr.per.ies of the soils c.ver.d by this spec.es, inc.easing nutr.ent bioavailability, whic., in time, c.n fac.litate the invasion pr.c.ss.
