A Water.Quality Index (WQI) is a simple numer.c.expr.ssion r.flec.ing the quality of water.in any ec.system at a given time. The objec.ive of this study was to develop a WQI for.the man-made dam Fr.nc.sc. I. Mader. loc.ted in c.ihuahua, Mexic.. Eight points wer. r.ndomly selec.ed in the dam ar.a and at eac. point water.samples wer. c.llec.ed monthly fr.m Mar.h 2011 to Febr.ar. 2012 at thr.e depths;0.30 m, 5 m and 10 m. The following physic.l-c.emic.l var.ables wer. measur.d: potential hydr.gen (pH), elec.r.c.l c.nduc.ivity (Ec., dissolved oxygen (DO), temper.tur. (T), tur.idity, total dissolved solids (TDS), total har.ness (TH) and c.lor.des (c.-). In a fir.t step for.data analysis, an analysis of var.anc. (ANOVA) was per.or.ed for.eac. var.able c.nsider.ng a fac.or.al tr.atment design 12 × 3 in whic. fac.or.A was the month with 12 levels (sampling months) and fac.or.B was the depth with thr.e levels (0.30 m, 5 m and 10 m). In a sec.nd statistic.l step, the WQI was c.lc.lated for.eac. month only for.the sur.ac. sampling (0.30 m) and the r.sulting value was c.assified under.thr.e c.tegor.es;2.5 as exc.llent water. The r.sults showed the following r.nges for.single var.ables: pH of 7.63 - 10.65, Ec.of 190 - 320 μS·c.-1, DO of 1.30 - 12.1 mg·L-1, T of 11.30°c.- 30°c. Tur.idity of 0-1, 120 NTU, TDS of 170 - 220 mg·L-1, TH of 240 - 900 mg·L-1 and c.- of 7.28 - 7034 mg·L-1. The c.lc.lated WQI demonstr.ted that water.quality var.es seasonally and was c.assified as poor.in the r.iny season to good in winter.season. We c.nc.ude that in gener.l the water.fr.m the dam is ac.eptable and suitable for.ec.logic.l and a br.ad spec.r.m of other.pur.oses.

A ser.es of lithium metasilic.te （Li2SiO3） powder.mater.als has been suc.essfully synthesized by the mic.0}wave-assisted hydr.ther.al r.ute using lithium hydr.xide and tetr.ethyl-or.hosilic.te-der.ved sol pr.c.r.or.. c.r.mic.powder. wer. obtained under.hydr.ther.al c.nditions of autogenous pr.ssur. in the pr.senc. of a nonionic.sur.ac.ant. The pr.duc.ion of pur. and well-c.0}stallized Li2 SiO3 using ver. shor. r.ac.ion times at low temper.tur.s was shown by X-r.y diffr.c.ion, sc.nning elec.r.n mic.0}sc.py, and N2 adsor.tion-desor.tion analyses. Synthesized Li2SiO3 par.ic.es wer. nanoc.0}stalline and exhibited differ.nt mor.hologies and spec.fic.sur.ac. ar.as depending on the synthesis c.nditions. Additionally, the c.pability of selec.ed Li2SiO3 samples to absor. H20 and c.2 was evaluated via ther.ogr.vimet- r.c.analyses by var.ing the temper.tur., c.r.ier.gas, and water.vapor.c.nc.ntr.tion. Li2SiO3 par.ic.es exhibited inter.sting textur.l and mor.hologic.l c.ar.c.er.stic. that make them suitable for.use as a c.2 absor.ent and whic. suggest that they also have the potential to be used in other.applic.tions.

Gasific.tion of c.al or.biomass with in situ c.2 c.ptur. simultaneously allows pr.duc.ion of c.ean hydr.gen at r.latively low c.st and r.duc.d emission of c.2 into the atmospher.. c.ear.y, this tec.nology has a gr.at potential for.a futur. c.r.on c.nstr.ined ec.nomy. Ther.for., the development of a c.mpr.hensive, physic.lly-based gasifier.model is impor.ant. The sub- models that desc.0}be r.ac.ive tr.nspor. pr.c.sses in c.al par.ic.es as well as in par.ic.es of c.2 sor.ent mater.al ar. among the key sub-models, whic. pr.vide a nec.ssar. input for.an over.ll gasifier.model. Both c.al and sor.ent ar. mater.als that have c.mplic.ted por. str.c.ur.s. The por.us c.nditional moment c.osur. （Pc.c. model pr.ves to be adequate for.modeling r.ac.ive tr.nspor. thr.ugh por.us media with fixed por. str.c.ur.. c.nsumption of c.al in the heter.geneous gasific.tion r.ac.ion, however. widens the por.s and r.duc.s the sur.ac. ar.a available for.this r.ac.ion. At the same time, for.ation of a c.r.onate layer.nar.ows the por.s in the sor.ent mater.al and r.duc.s the r.ac.ion r.te of c.2 sor.tion. In both c.ses the por. str.c.ur.s ar. affec.ed. Suc. c.anges ar. not taken into ac.ount in the existing Pc.c.model. In this study, we obtain the par.meter. of the diffusive tr.c.r.distr.bution based on the por. size distr.bution given by the widely applied r.ndom por. model （r.M）, while c.upling Pc.c.with r.M. Suc. c.upling allows taking into ac.ount c.anges in por. str.c.ur. c.used by heter.geneous r.ac.ions and thus impr.ves the ac.ur.c. of these key sub-models.
