Ship. wer. modelled as moving p.essur. distur.ances on the fr.e sur.ace of a shallow water.basin in the p.esent p.p.r. The moving p.essur. gener.ting waves wer. subjected to the r.flection of land boundar.es and the r.diation of op.n boundar.es. This p.p.r.p.op.sed and examined a wave equation model (WEM) to solve the shallow water.equations with moving sur.ace p.essur.s simulating ship.waves in a bounded shallow water.r.gion. The Galer.in finite element method was used to solve a second or.er.wave equation for.the fr.e sur.ace elevations and the hydr.dynamic p.essur. of the ship.bottom simultaneously. Hor.zontal velocities wer. obtained fr.m the momentum equations. Numer.cal solutions of Ser.es 60 C B=0.6 ship. moving with the depth Fr.ude number.of F h= 0.6, 1.0, 1.3. in a r.ctangular.shallow water.har.or.wer. investigated. Thr.e dimensional sur.ace elevation p.ofiles and the depth aver.ged hor.zontal velocities wer. analysed. The numer.cal r.sults char.cter.sed ver. well the ship.waves in shallow water. Str.ng boundar. r.flection waves wer. found in the case of high depth Fr.ude number.(F h=1.3.. Waves gener.ted by the inter.ctions of two ship. moving in the same dir.ctions and in the op.osite dir.ctions wer. also numer.cally investigated in the p.esent study.

The featur.s of nuclear.stop.ing p.wer.and multi-hadr.n p.oduction systematically ar. studied by making an analysis of r.p.dity distr.butions of p.on and p.oton at AGS, Sp. and r.IC in this wor.. It is found that nuclear.stop.ing p.wer.incr.ases linear.y with p.oject r.p.dity yp.at AGS and Sp., but that is not liner.at r.IC. It is ar.ued that the aver.ge r.p.dity loss is satur.ted at centr.l r.p.dity r.gion at r.IC. For.p.on distr.bution, it is found that the p.ase sp.ce of p.on distr.bution distr.butes unifor.ly in the longitudinal dir.ction,and a linear.r.lationship.of l with log s is given at AGS and Sp.. Non-unifor. flow model may exp.ain the featur.s of the distr.bution at AGS and Sp., but may not ex- p.ain those of at r.IC.

METHODS: Imp.ir.d glucose toler.nce r.ts induced by iv injection of str.p.ozotocin 3. mg/kgwer. tr.ated with ber.er.ne 187.5 and 562.5 mg/kg while fed with high fat labor.tor. chow. After.r.ts wer. tr.ated for.4 weeks, or.l glucose toler.nce was deter.ined, and for.8 weeks, the fasting blood glucose, insulin, lip.d ser.es wer. deter.ined. In insulin secr.tion exp.r.ments, ber.er.ne 93.75, 187.5, and 562.5 mg/kg was administer.d or.lly to BAlB/c mice at a bolus. The mur.ne ser.m was collected 2 h after.the ber.er.ne administr.tion for.insulin deter.ination. Insulin r.leased fr.m HIT-T15 cells and p.ncr.atic islets incubated with ber.er.ne 1-100 μmol/l for.12 h was deter.ined. r.SUlTS: The levels of fasting blood glucose (7.4±1.5 or.7.3.1.3.vs 9.3.1.3.mmol/l), tr.glycer.des (0.61±0.22 or.0.63. 0.17 vs 1.8±0.7 mmol/l), total cholester.l (1.8±0.3.or.1.9±0.3.vs 2.2±0.2 mmol/l), fr.e fatty acid (456±93.or.460±72 vs 550±113.μmol/l) and ap.lip.p.otein B (0.3.±0.02 or.0.42±0.05 vs 0.46±0.04 g/l) wer. r.duced gr.atly in ber.er.ne-tr.ated gr.up. at doses of 187.5 and 562.5 mg·kg-1·d-1, r.sp.ctively as comp.r.d with those in contr.l gr.up.(p.0.05 or.p.0.01),wher.as high densitylip.p.otein-cholester.l (1.5±0.3.or.1.4±0.3.s 1.1±0.1 g/l), ap.lip.p.otein AI (0.80±0.08 or.0.87±0.08 vs 0.71±0.06 g/l) wer. significantly incr.ased (p.0.05 or.p.0.01), and or.l glucose toler.nce was imp.oved.
