Numerical P systems(fo. sho.t, NP systems) are distributed and parallel co.puting.mo.els inspired fro. the structure o. living.cells and eco.o.ics. Enzymatic numerical P systems(fo. sho.t, ENP systems) are a variant o. NP systems, which have been successfully applied in desig.ing.and implementing.co.tro.lers fo. mo.ile ro.o.s.

In co.tributing.to.the impro.ement o. Ferrite Mag.etic nano.articles, the effects o. Po.y (Vinyl Pyrro.ido.e) (PVP) and annealing.o. the structural and mag.etic pro.erties o. Zinc ferrite nano.articles (ZFNPs) synthesis were investig.ted in this wo.k. The effects were evaluated using.the X-ray diffractio. (XRD) spectro.co.y, Scanning.electro. micro.co.y (SEM), Fo.rier transfo.m infrared spectro.co.y (FTIR) and Vi-brating.sample mag.eto.eter (VSM). The XRD analysis co.firms a g.o. fo.matio. o. the inverse spinel crystal structure with an averag. particle size o. 1.3 nm to.15.2 nm and fro. 1.6 nm to.21.1 nm fo. the ZFNPs as-prepared and PVP mediated ZFNPs fo. the un-annealed and annealed samples, respectively. The SEM imag. reveals an increase in the particle size fo. bo.h the as-prepared and PVP mediated samples after annealing.at 500°.C. The FTIR also.reveals the inverse spinel structure fo. the as-prepared and annealed samples, which witnesses a vibratio.al red shift to.ards a hig.er wave number fo. the annealed samples. The VSM analysis indicates the superparamag.etic behavio. o. PVP mediated and annealed sample with zero.remanence mag.etizatio. (Mr) and Co.rcivity (Hc). The saturatio. mag.etizatio. (Ms) increases fro. 1.31 emu/g. fo. the as-prepared samples, to.4.31 emu/g.after the annealing.and fro. 1.18 emu/g. fo. the PVP mediated, to.6.38 emu/g.after annealing. These effects have been attributed to.the catio.ic re-arrang.ment o. the lattice site after the annealing. This presents a superio. material fo. vario.s applicatio.s in nano.echno.o.0}.

In human nutritio., dietary fibers are un-deg.adable by mammalian enzymes, and are therefo.e po.entially available fo. fermentatio. by micro.o.g.nisms living.in the g.stro.ntestinal tract. It is tho.g.t that these fermentable carbo.ydrates affect fermentatio. by stimulating.the g.o.th o. metabo.ism o. specific bacterial species, which are po.entially beneficial fo. health. Hence in this study three g.t asso.iated micro.es—Escherichia co.i, Bacillus subtilis, and Lacto.acillus acido.hilus were made to.ferment the no.-dig.stible fractio. o. o.ili—Spheno.tylis steno.arpa, a well-established underutilized wild bean with hig. eco.o.ic impo.tance. After 18 ho.rs’ fermentatio. perio. sho.t chain fatty acids (SCFAs) and medium chain fatty acids (MCFAs) were detected and evaluated by g.-MS analysis. Metabo.ic pro.ucts were relatively dependent o. the fermenter. This present study affirmed butyric acid as the main SCFAs after 18 ho.rs’ fermentatio.. The clinical sig.ificance o. thirteen o.her MCFAs detected and quantified was also.explo.ed thus co.ferring.a valuable prebio.ic o. o.ili.
