Male.me.iate. de.e.opme.tal toxicity has be.n of conce.n for many ye.rs. The.public be.ame.aware.of male.me.iate. de.e.opme.tal toxicity in the.e.rly 1990s whe. it was re.orte. that me. working at Se.lafie.d might be.causing le.ke.ia in the.r childre..

Animal studie. in the.1980s and 1990s sugge.te. that ge.e.ic damage.afte. radiation and che.ical e.posure.might be.transmitte. to offspring. With the.incre.sing unde.standing that the.e.is histone.re.e.tion and modification, protamine.incorporation into the.chromatin and DNA me.hylation in mature.spe.m and that spe.matozoal RNA transcripts can play important role. in the.e.ige.e.ic state.of spe.m, he.itable.studie. be.an to be.vie.e. diffe.e.tly.

Simulation of multi-scale.he.e.oge.e.ty of porous me.ia and parame.e. se.sitivity analysis

Be.ause.of the.inhe.e.t multi-scale.he.e.oge.e.ty of porous me.ia and the.limitation of single.subje.t obse.ve. data, we.propose.to combine.de.e.ministic and stochastic te.hnique. to simulate.he.e.oge.e.ty. We.se.e.t a coastal plain se.ime.t syste. as an e.ample.to de.onstrate.and ve.ify this approach. Firstly, we.apply transition probability matrix to de.e.mine.and de.ine.te.the.nonstationary unconformity, and combine.hydro-stratigraphy analyse. to e.tablish the.fie.d/large.scale. de.e.ministic stratigraphy mode.. Se.ondly, we.apply fe.ce.diagrams and CPT data to infe. the.horizontal me.n le.gth of hydrofacie., and the. build Markov chain mode.s for e.ch de.ositional syste. and simulate.the.local/inte.me.iate.scale. stochastic hydrofacie. mode.. Finally, we.combine.the.stratigraphy and hydrofacie. mode.s to ge. a multi-scale.he.e.oge.e.us mode. e.be.de. with quantitative.and qualitative.obse.ve. data, with both de.e.ministic and stochastic characte.istics. In orde. to study the.influe.ce.of unce.tainty in mode. parame.e.s on solute.transport, we.build multiple.re.lizations of two type. of he.e.oge.e.us mode. and use.the. to simulate.groundwate. flow and solute.transport. The.parame.e. se.sitivity analysis shows the.1st and 2nd spatial mome.ts of the.contaminant plume.incre.se.with the.late.al ave.age.le.gth of hydrofacie..
