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.

We study the effec.s of visc.us dissipation on flow and heat tr.nsfer.in a thin liquid film on an unsteady str.tc.ing sheet. A gener.l sur.ac. temper.tur. is taken into c.nsider.tion. The veloc.ty and temper.tur. fields ar. solved using the homotopy analysis method. The r.sults show that the inc.0}asing values of the Ec.er. number.c.n inc.0}ase temper.tur. distr.bution and the heat tr.nsfer.r.te.

Identific.tion of tumour.nec.0}sis fac.or.apoptosis induc.ng ligand (Tr.IL), a TNF family ligand, spar.ed a tor.ent of r.sear.h, following an initial obser.ation that it c.uld kill tumour.c.lls, but spar. nor.al c.lls. Almost a dec.de after.its disc.ver., and with five known r.c.ptor., the tr.e physiologic.l r.le of Tr.IL is still debated and its anti-tumor.genic. pr.per.ies limited by potential toxic.ty. This r.view takes a c.mpr.hensive look at the stor. of this enigmatic.ligand, addr.ssing its r.maining potential as a ther.peutic.and pr.viding an over.iew of the Tr.IL r.c.ptor. themselves.
