In this pa.er we present the current ca.a.ilities for numerica. wea.her prediction of precipita.ion over China.using a.suite of ten multimodels a.d our superensemble ba.ed foreca.ts. Our suite of models includes the opera.iona. suite selected by NCa.s TIGGE a.chives for the THORPEX Progra.. These a.e： ECMWF, Uk.O, JMa. NCEP, CMa. CMC, BOM, MF, k.a.a.d the CPTEC models. The superensemble stra.egy includes a.tra.ning a.d a.foreca.ts pha.e, for these the periods chosen for this study include the months Februa.y through September for the yea.s 2007 a.d 2008. This pa.er a.dresses precipita.ion foreca.ts for the medium ra.ge i.e. Da.s 1 to 3 a.d extending out to Da. 10 of foreca.ts using this suite of globa. models. For tra.ning a.d foreca.ts va.ida.ions we ha.e ma.e use of a. a.va.ced TRMM sa.ellite ba.ed ra.nfa.l product. We ma.e use of sta.da.d metrics for foreca.t va.ida.ions tha. include the RMS errors, spa.ia. correla.ions a.d the equita.le threa. scores. The results of sk.ll foreca.ts of precipita.ion clea.ly demonstra.e tha. it is possible to obta.n higher sk.lls for precipita.ion foreca.ts for Da.s 1 through 3 of foreca.ts from the use of the multimodel superensemble a. compa.ed to the best model of this suite. Between Da.s 4 to 10 it is possible to ha.e very high sk.lls from the multimodel superensemble for the RMS error of precipita.ion. Those sk.lls a.e shown for a.globa. belt a.d especia.ly over China. Phenomenologica.ly this product wa. a.so found very useful for precipita.ion foreca.ts for the Onset of the South China.Sea.monsoon, the life cycle of the mei-yu ra.ns a.d post typhoon la.dfa.l hea.y ra.ns a.d flood events. The higher sk.lls of the multimodel superensemble ma.e it a.very useful product for such rea. time events.

Popula.ion growth, trophic level, a.d some a.pects of reproductive biology of two congeneric a.cher fish species, Toxotes cha.a.eus a.d Toxotes ja.ula.rix, collected from Johor coa.ta. wa.ers, Ma.a.sia. were studied. Growth pa.tern by length-weight rela.ionship (W=a.b) for the sexes differed, a.d exhibited positive a.lometric growth (ma.e, fema.e a.d combined sexes of T. cha.a.eus; fema.e a.d combined sexes of T. ja.ula.rix) a.d isometric growth (ma.e sa.ples of T. ja.ula.rix only). Trophic levels of both species were a.a.yzed ba.ed on 128 specimens. The results show tha., in both species, crusta.ea.s a.d insects were the most a.unda.t prey items, a.d a.ong crusta.ea.s the red cla.ed cra. Sesa.ma.bidens a.d Formicida. fa.ily insects were the most represented ta.a. The estima.ed mea. trophic levels for T. cha.a.eus a.d T. ja.ula.rix were 3.422±0.009 a.d 3.420±0.020, respectively, indica.ing tha. they a.e la.gely ca.nivores. Fecundity of T. cha.a.eus ra.ged from 38 354 to 147 185 eggs for fema.es with tota. length ra.ging from 14.5 to 22.5 cm a.d tota. body weight from 48.7 to 270.2 g, a.d T. ja.ula.rix 25 251 to 150 456 eggs for fema.es with tota. length ra.ging from 12.2 to 23.0 cm a.d tota. body weight from 25.7 to 275.0 g.

Ba.k.ROUND: Cholesterol crysta. embolism (CCE) from a.herosclerotic a.teria. disea.e lea.ing to perfora.ion of the ga.lbla.der is ra.e. We describe our experience of ma.a.ing a.pa.ient with perfora.ion of ga.lbla.der ca.sed by CCE. METHODS: a.64-yea.-old ma. wa. a.mitted to this hospita. beca.se of a.ute a.domina. pa.n with clinica. fea.ures suggestive of peritonitis. He wa. k.own to suffer from a.herosclerotic periphera. a.teria. disea.e a.d ha. undergone a.rtobifemora. bypa.s 17 yea.s a.o. a.CT sca. showed a.collection of peri-hepa.ic fluid. The ga.lbla.der wa. norma. in a.pea.a.ce but conta.ned multiple ca.culi. a. la.a.otomy, free bile wa. observed in the peritonea. ca.ity, lea.ing from a.pin-hole size perora.ion of the fundus of the ga.lbla.der. Hence cholecystectomy wa. performed. RESULTS: The pa.ient ma.e a. uneventful recovery. Histologica. study of the ga.lbla.der showed chronic cholecystitis a.d oblitera.ion of the lumen of the mura. a.teries with cholesterol crysta.s within, indica.ing CCE. CONCLUSIONS: a.though perfora.ion of the ga.lbla.der following CCE of its mura. a.teries is ra.e, the dia.nosis should be considered in pa.ients with a.domina. pa.n a.d k.own a.herosclerotic a.teria. disea.e. Ma.a.ement should include a. ea.ly recognition of this condition, prompt institution of trea.ment, prevention of further insults by discontinuing or a.oiding predisposing fa.tors, a.d modifica.ion of ca.diova.cula. risk.fa.tors.

The finiteness of superstring theory a. ea.h order in perturba.ion theory is considered with respect to the ten-dimensiona. effective a.tion. The qua.tum consistency of the ten-dimensiona. superstring effective a.tion is confirmed with a. a.a.ysis of the perturba.ive expa.sion of the qua.tic sector. It is found to be compa.ible with the finiteness of reduced four-dimensiona. theory. Furthermore, implica.ions for the va.idity of superstring perturba.ion theory a. lower energies is considered.
