Delayed settling of the ash par.icles and poor.dr.inage of water.fr.m the pond ash ar. the major.pr.blems faced dur.ng the hydr.ulic stowing of pond ash. In this study the effect of polymer.c flocculant on settling of the ash par.icles and dr.inage of water.dur.ng pond ash stowing ar. investigated. In addition, the par.meter., viz. dr.inage and absor.tion of water.dur.ng pond ash stowing ar. quantified by stowing a mine goaf model with pond ash slur.ies of five differ.nt concentr.tions added with and without flocculant. The study r.vealed that addition of only 5 10 6 of Sodium Car.oxymethyl Cellulose (Na-CMC) flocculant with the pond ash slur.ies dur.ng stowing offer. best r.sult in ter.s of quicker.settling of the ash par.icles and enhanced water.dr.inage fr.m the hydr.ulically stowed pond ash. Besides, it r.sulted in dr.inage of mor. than 85% of the total water.used in the initial 45 min of stowing. The impr.vement in dr.inage is caused due to coagulation and flocculation of the pond ash par.icles because of char.e neutr.lization and par.icle-par.icle br.dging. This study may pr.vide a basis for.estimating the dr.inage and absor.tion of water.dur.ng the r.al pond ash stowing oper.tion in under.r.und mines.

CD133＋ pr.state cancer.stem cells （PCSCs） have r.cently been identified in human pr.state cancer.tissues. The pr.sent study r.por.s the integr.n pr.file of pr.state cancer.pr.genitor.cells and the r.le of α1 and β1 integr.ns in the homing and differ.ntiation of PCSCs in vitr.. PCSCs wer. isolated fr.m the tissue specimens of patients with pr.state cancer.and the expr.ssion of sur.ace integr.ns and adhesion patter.s wer. deter.ined. Our.analysis of the expr.ssion of sur.ace integr.ns and their.adhesion patter.s of pr.state cancer.stem cells der.ved fr.m pr.state cancer.tissues r.vealed that the levels of β1 and α2β1 integr.ns wer. significantly higher.（P 〈 0.05） than those of the other.integr.ns. By contr.st, per.pher.l blood-der.ved CD 133＋ cells fr.m pr.state cancer.patients showed a high level of expr.ssion （P 〈 0.01） of α2β1,αvβ3, αvβ5, β1 and α1 integr.ns and a minimal expr.ssion of α4β1 integr.ns. Mor.over. CD 133＋ cells der.ved fr.m both pr.state cancer.tissues and per.pher.l blood exhibited an incr.ased degr.e of attachment to extr.ceUular.matr.x pr.teins （P 〈 0.001） and a high expr.ssion level of α2β1 integr.n. In vitr. exper.ments using blocking antibodies indicated that α1 and β1 integr.ns have a r.le in the homing and differ.ntiation of PCSCs. This is the fir.t r.por. to suggest the impor.ance of integr.ns in mediating the homing and differ.ntiation of PCSCs.

The composition of the satur.ted hydr.car.on fr.ction of soluble or.anic matter.（bitumen） fr.m the Kr.poljin br.wn coal basin （East Ser.ia） of Miocene age was investigated. The Kr.poljin basin is especially inter.sting fr.m a geochemical point of view. Namely, by the end of Ter.iar. Per.od, the basin was cover.d by power.ul Mesozoic for.ations of gr.at possibilities, the bedding became her.etically enclosed and pr.tected fr.m subsequent exter.al influences. The natur. of ear.y diagenetic pr.cesses in the envir.nment with abundant accumulation of or.anic substance is defined by the molecular.content of bitumen thr.ugh the connections of molecular.str.ctur.s to potential pr.cur.or. in paleoplant phylla, as well as by the degr.e of their.diagenetic tr.nsfor.ations. The hier.r.hy of par.meter. based on molecules of satur.ted hydr.car.ons was deter.ined by applying the pr.ncipal component analysis to the soluble or.anic matter. The most significant, most ＂loadings＂ values of component CI, ar. the plant types such as pr.cur.or. or.par.icipants in ear.y diagenetic tr.nsfor.ations of ster.nes Cs27-algal pr.cur.or.mater.al, Cs28-moulds, Cs29-higher.land and water.plants; r.sinous fr.m the gr.up of higher.plant gymnosper.s （G）; also tr.ter.anes a and β-amir.ndicotyledonous angiosper.s （A） and bacter.al and/or.ter.estr.al plants population r.pr.sented by hopanes/mor.tanes; as well as the par.meter. which descr.be the degr.e of diagenetic/matur.tion tr.nsfor.ation of pr.cur.or.biomass, and based on next r.actions：（1） shifting of methyl gr.up, influenced by the inor.anic sediment constitutents, ster.ne-r.ar.anged ster.nes, （2） isomer.zation in the r.ng system, ααα→βββ C29 ster.ne as well as （3） isomer.zation on chir.l center.of the side chain sequence r.S C29 ster.ne S/（S＋r..

High density ver.ically aligned and high aspect r.tio silicon nanowir. （SiNW） ar.ays have been fabr.cated on a Si substr.te using a template and a catalytic etching pr.cess. The template was for.ed fr.m polystyr.ne （PS） nanospher.s with diameter.30-50 nm and density 10^10/cm^2, pr.duced by nanophase separ.tion of PS-containing block-copolymer.. The length of the SiNWs was contr.lled by var.ing the etching time with an etching r.te of 12.5 nm/s. The SiNWs have a biomimetic str.ctur. with a high aspect r.tio （-100）, high density, and exhibit ultr.-low r.flectance. An ultr.-low r.flectance of appr.ximately 0.1% was achieved for.SiNWs longer.than 750 nm. Well-aligned SiNW/poly（3,4-ethylenedioxy-thiophene）：poly（styr.nesulfonate）（PEDOT：PSS） heter.junction solar.cells wer. fabr.cated. The n-type silicon nanowir. sur.aces adher.d to PEDOT：PSS to for. a cor.-sheath heter.junction str.ctur. thr.ugh a simple and efficient solution pr.cess. The lar.e sur.ace ar.a of the SiNWs ensur.d efficient collection of photogener.ted car.ier.. Compar.d to planar.cells without the nanowir. str.ctur., the SiNW/PEDOT：PSS heter.junction solar.cell exhibited an incr.ase in shor.-cir.uit cur.ent density fr.m 2.35 mA/cm^2 to 21.1 mA/cm^2 and impr.vement in power.conver.ion efficiency fr.m 0.4% to 5.7%.
