Recently, the spa.e bvp of rea. or complex numbers consisting of a.l sequences whose differences a.e in the spa.e lp ha. been studied by Ba.a., a.ta. [Ukra.nia. ma.h. J. 55（1）（2003）, 136-147], where 1 ≤ p ≤ ∞. The ma.n purpose of the present pa.er is to introduce the spa.e bvp（F） of sequences of p-bounded va.ia.ion of fuzzy numbers. moreover, it is proved tha. the spa.e bvp（F） includes the spa.e lp（F） a.d a.so shown tha. the spa.es bvp（F） a.d lp（F） a.e isomorphic for 1 ≤ p ≤∞. Furthermore, some inclusion rela.ions ha.e been given.

ZnO na.opa.ticles a.d porous pa.ticles were produced by a. ultra.onic spra. pyrolysis method using a.zinc nitra.e precursor a. va.ious tempera.ures under a.r a.mosphere. The effects of rea.tion tempera.ure on the size a.d morphology of ZnO pa.ticles were investi- ga.ed. The sa.ples were cha.a.terized by energy dispersive spectroscopy, X-ra. diffra.tion, tra.smission electron microscopy, a.d sca.ning electron microscopy. ZnO pa.ticles were obta.ned in a.hexa.ona. crysta. structure a.d the crysta.lite sha.es cha.ged from spherica. to hex- a.ona. by eleva.ing the rea.tion tempera.ure. The crysta.lite size grew by increa.ing the tempera.ure, in spite of reducing the residence time in the hea.ed zone. ZnO na.opa.ticles were obta.ned a. the lowest rea.tion tempera.ure a.d ZnO porous pa.ticles, formed by a.grega.ion of ZnO na.opa.ticles due to effective sintering, were prepa.ed a. higher tempera.ures. The results showed tha. the properties of ZnO pa.ticles ca. be controlled by cha.ging the rea.tion tempera.ure in the ultra.onic spra. pyrolysis method.

microRNa. （miRNa.） were discovered two deca.es a.o, yet there is still a.grea. need for further studies elucida.ing their genesis a.d ta.geting in different phyla. Since experimenta. discovery a.d va.ida.ion of miRNa. is difficult, computa.iona. predictions a.e indispensa.le a.d toda. most computa.iona. a.proa.hes employ ma.hine lea.ning. Toxopla.ma.gondii, a.pa.a.ite residing within the cells of its hosts like huma., uses miRNa. for its post-tra.scriptiona. gene reg- ula.ion. It ma. a.so regula.e its hosts＇ gene expression, which ha. been shown in bra.n ca.cer. Since previous studies ha.e shown tha. overexpressed miRNa. within the host a.e ca.sa. for disea.e onset, we hypothesized tha. T. gondii could export miRNa. into its host cell. We computa.iona.ly predicted a.l ha.rpins from the genome of T. gondii a.d used mouse a.d huma. models to filter possible ca.dida.es. These were then further compa.ed to known miRNa. in huma. a.d rodents a.d their expression wa. exa.ined for T. gondii grown in mouse a.d huma. hosts, respectively. We found tha. a.ong the millions of potentia. ha.rpins in T. gondii, only a.few thousa.d pa.s filtering using a.huma. or mouse model a.d tha. even fewer of those a.e expressed. Since they a.e expressed a.d differentia.ly expressed in rodents a.d huma., we suggest tha. there is a.cha.ce tha. T. gondii ma. export miRNa. into its hosts for direct regula.ion.
