One method for identifying nonc.ding regulatory regions.of a genome is.to quantify rates.of divergenc. between related s.ec.es. as.func.ional s.quenc. will generally diverge more s.owly. Mos. approac.es.to identifying thes. c.ns.rved nonc.ding s.quenc.s.（c.s.） bas.d on alignment have had relatively large minimum s.quenc. lengths.（≥15 bp） c.mpared with the average length of known trans.0}iption fac.or binding s.tes. To c.rc.mvent this.c.ns.raint, s.AG-c.s.that c.n s.multaneous.y integrate the data from the promoters.of c.ns.rved orthologous.genes.in three or more s.ec.es.was.developed. Us.ng the data from up to s.x gras. s.ec.es.made it pos.ible to identify c.ns.rved s.quenc.s.as.s.ort as.9 bp with fals. dis.0}very rate ≤0.05. Thes. c.s. exhibit greater overlap with open c.romatin regions.identified us.ng DNas. I hypers.ns.tivity as.ays. and are enric.ed in the promoters.of genes.involved in trans.0}iptional regulation. s.AG-c.s.was.further employed to c.arac.erize los. of c.ns.rved nonc.ding s.quenc.s.as.oc.ated with retained duplic.te genes.from the anc.ent maize polyploidy. Genes.with fewer retained c.s. s.ow lower overall expres.ion, although this.bias.is.more apparent in s.mples.of c.mplex organ s.s.ems.c.ntaining many c.ll types. s.gges.ing that c.s.los. may c.rres.ond to a reduc.d number of expres.ion c.ntexts.rather than lower expres.ion levels.ac.os. the entire anc.s.ral expres.ion domain.

Introduc.ion and evaluation of a novel hybrid brattic. for improved dus. c.ntrol in underground mining fac.s. A c.mputational s.udy

作者： Kurnia Jundika c. s.s.ito Agus.P. Has.ani Ferri P. Mujumdar Arun s. Mec.anic.l Engineering Department Universiti Teknologi PETRONAS Department of Mining and Materials.Engineering McGill University

A proper c.ntrol and management of dus. dis.ers.on is.es.ential to ens.re s.fe and produc.ive underground working environment. Brattic. ins.allation to direc. the flow from main s.aft to the mining fac. was.found to be the mos. effec.ive method to dis.ers. dus. partic.e away from the mining fac.. However,it limits.the movement and dis.urbs.the flexibility of the mining fleets.and operators.at the tunnel. This.s.udy propos.s.a hybrid brattic. s.s.em- a c.mbination of a phys.c.l brattic. together with s.itable and flexible direc.ed and loc.ted air c.rtains. to mitigate dus. dis.ers.on from the mining fac. and reduc. dus. c.nc.ntration to a s.fe level for the working operators. A validated three-dimens.onal c.mputational fluid dynamic.model utilizing Eulerian–Lagrangian approac. is.employed to trac. the dis.ers.on of dus. partic.e. s.veral pos.ible hybrid brattic. s.0}narios.are evaluated with the objec.ive to improve dus. management in underground mine. The res.lts.s.gges. that implementation of hybrid brattic. is.benefic.al for the mining operation: up to three times.lower dus. c.nc.ntration is.ac.ieved as.c.mpared to that of the phys.c.l brattic. without air c.rtain.

This.s.udy aims.to predic. monthly c.lumnar ozone in Penins.lar Malays.a bas.d on c.nc.ntrations.of s.veral atmos.heric.gas.s. Data pertaining to five atmo- s.heric.gas.s.（c.2, 03, c.4, NO2, and H2O vapor） were retrieved by s.tellite s.0}nning imaging abs.rption s.ec.ro- metry for atmos.heric.c.artography from 2003 to 2008 and us.d to develop a model to predic. c.lumnar ozone in Penins.lar Malays.a. Analys.s.of the northeas. mons.on （NEM） and the s.uthwes. mons.on （s.M） s.as.ns.were c.nduc.ed s.parately. Bas.d on the Pears.n c.rrelation matric.s. c.lumnar ozone was.negatively c.rrelated with HzO vapor but pos.tively c.rrelated with c.z and NO2 during both the NEM and s.M s.as.ns.from 2003 to 2008. This.res.lt was.expec.ed bec.us. NO/is.a prec.rs.r of ozone. Therefore, an inc.eas. in c.lumnar ozone c.nc.ntration is.as.oc.ated with an inc.eas. in NO2 but a dec.eas. in H/O vapor. In the NEM s.as.n, c.lumnar ozone was.negatively c.rrelated with H20 （-0.847）, NO2 （0.754）, and c.2 （0.477）; c.lumnar ozone was.als. negatively but weakly c.rrelated with c.4 （-0.035）. In the s.M s.as.n, c.lumnar ozone was.highly pos.tively c.rrelated with NO2 （0.855）, c.2 （0.572）, and c.4（0.321） and als. highly negatively c.rrelated with H2O（-0.832）. Both multiple regres.ion and princ.pal c.mponent analys.s.were us.d to predic. the c.lumnar ozone value in Penins.lar Malays.a. We obtained the bes.-fitting regres.ion equations.for the c.lumnar ozone data us.ng four independent variables. Our res.lts.s.ow approxi- mately the s.me R value （≈0.83） for both the NEM and s.M s.as.ns.

A wildc.t may not res.lt in a petroleum pros.ec.; however, it may indic.te potential need for frontier explo- ration, s.nc. petroleum c.uld leak into ec.nomic.ac.umu- lations. c.rbazoles.and benzoc.rbazoles.are nitrogen c.mpounds.in petroleum and c.n be employed to explic.tly explain migration direc.ion and dis.anc. of leaking petro- leum. The hypothes.s.of this.s.udy is.that the mec.anis. of the reac.ion involving the attrac.ion of c.rbazoles.to c.ay minerals.on the matrix of the walls.along their migration pathways.determines.the is.mer that is.preferentially attac.ed to the mineral matrix. The objec.ives.of this.s.udy are （a） to produc. a profile for c.rbazoles.and benzoc.r- bazoles.ratios.in the c.p roc. overlying the res.rvoir, （b） to c.mpare c.rbazole and benzoc.rbazole ratios.to 20s. （20s.＋ 20R）（^（^c.9 s.erane maturity ratios.（c. to infer migration direc.ion from the c.rbazoles.and benzoc.r- bazoles.ratio. s.mples.us.d were s.de wall c.res.and drill c.ttings.of water-bas.d mud drilling. The EOM （ex- trac.able organic.matter） from various.formations.overlying the res.rvoir was.obtained us.ng s.xtherm Automatic.Equipment. The TPH （total petroleum hydroc.rbon） was.obtained from the EOM by us.ng a prec.eaned is.lute c.8 500 mg / 3 mL c.lumn, eluted with hexane, while the polars.were eluted with dic.loromethane. Frac.ionation into s.tu- rates.and aromatic. was.done us.ng a s.lver nitrate-s.lic. gel c.lumn. The profiles.of 1,8/1,3 and 1,8/2,4 dimethyl c.r- bazoles.and the benzoc.rbazoles.ratios.s.ow a vertic.l gra- dient of dec.eas.ng ratio with inc.eas.ng vertic.l dis.anc. from the res.rvoir.

Here, we inves.igated the effec.s.of dietary pH on whitefly （Bemis.a tabac.） feeding behavior and releas. of Lettuc. infec.ious.yellows.virus.（LIYV） virions.retained in the vec.or＇s.foregut. Elec.ric.l penetration graph analys.s.revealed that variables.as.oc.ated with whitefly probing and inges.ion did not differ s.gnific.ntly in pH （4, 7.4, and 9） adjus.ed artific.al diets. To inves.igate virus.retention and releas., whiteflies.allowed to ac.uire LIYV virions.in a pH 7.4 artific.al diet were fed pH 4, 7.4, or 9 virion-free artific.al （c.earing） diets. Immunofluores.0}nt loc.lization analys.s.indic.ted that virions.remained bound to the foreguts.of approximately 20%-24% of vec.ors.after they fed on eac. of the 3 pH- adjus.ed c.earing diets. When RNA preparations.from the c.earing diets.were analyzed by revers. trans.0}iption （RT） nes.ed-Pc. and, in s.me c.s.s. real-time qPc., s.c.es.ful amplific.tion of LIYV-s.ec.fic.s.quenc. was.infrequent but c.ns.s.ently repeatable for the pH 7.4 diet but never obs.rved for the pH 4 and 9 diets. s.gges.ing a weak pH-dependent effec. for virion releas.. Viruliferous.vec.ors.that fed on eac. of the 3 pH-adjus.ed c.earing diets.trans.itted LIYV to virus.free plants. Thes. res.lts.s.gges. that c.anges.in pH values.alone in artific.al diet do not res.lt in obs.rvable c.anges.in whitefly feeding behaviors. an obs.rvation that marks.a firs. in the feeding of artific.al diet by whitefly vec.ors. and that there is.a potential c.us.l and c.ntingent relations.ip between the pH in artific.al diet and the releas./inoc.lation of foregut bound virions.
