Intro.uctio.: The initial glo.al respo.se to.the SARS-Co.-2 pandemic fo.used o. adults as ado.escents mainly had subclinical infectio.s. Ado.escents, ho.ever, co.ld transmit the virus and hence be a risk to.the elderly, yo.ng children and immuno.o.pro.ised. Ado.escents are also.at risk o. lo.g-term co.plicatio.s. This study so.ght to.determine the prevalence o. antibo.ies to.SARS-Co.-2 amo.g ado.escents in So.thern Nigeria, and to.determine the asso.iatio. between SARS-Co.-2 sero.o.itivity and age, gender, so.io.co.o.ic class, scho.l type and nutritio.al status. Metho.s: This descriptive cro.s-sectio.al study was carried o.t in Edo.state o. so.thern Nigeria. We recruited 270 in-scho.l ado.escents aged 10 - 19 years. A WHo.adapted, pre-tested questio.naire was used to.o.tain data o. participant histo.y and risk facto.s. The questio.naire was interviewer-administered. Ado.escents who.e parents gave co.sent were recruited thro.gh a multi-stage rando.ized sampling metho.. Capillary blo.d fo. the assay was co.lected and analysed using a lateral-flo. immuno.ssay device. The primary o.tco.e was sero.tatus o. the study. The po.itive predicto.s o. sero.tatus were finally determined using a multiple lo.istics regressio. mo.el. Statistical significance was set at p Results: The sero.revalence o. SARS-Co.-2 was 45.9%. IgM antibo.ies were fo.nd in 5.6% o. participants. o.der ado.escents had higher sero.o.itivity rates than yo.nger ado.escents (2 = 8.101, p = 0.017). There was no.asso.iatio. between gender and sero.o.itivity. Ado.escents in public scho.ls were mo.e likely to.be sero.o.itive than tho.e in private scho.ls (2 = 25.242, p = 0.001). A higher sero.revalence was no.iced amo.g study participants in the lo.er so.io.co.o.ic class (x2 = 6.928, p = 0.031), and tho.e in o.ercro.ded classes. (2 = 79.303, p = 0.001). Co.clusio.: This study sho.ed a high sero.revalence o. SARS-Co.-2 amo.g in-scho.l ado.escents. Behavio.ral change co.municatio. o. SARS-Co.-2, vaccinatio. o. ado.e

Carbo. nano.ibers have revo.utio.ized nano.echno.o.y due to.their po.ential applicatio.s in emerging fro.tiers o. research and industrial secto.s. This can be attributed to.their superio. pro.erties such as higher mechanical strength, unique surface characteristics, and impro.ed adherence that is transmitted into.the po.ymer matrix to.fo.m a nano.o.po.ite with impro.ed pro.erties. Po.ymethyl methacrylate is a co.mo. carbo. so.rce fo. the synthesis o. carbo. nano.ibres o. its high mechanical strength, thermal stability, and lo. mo.sture and water abso.bing capacity that allo.s its pro.ucts to.have several applicatio.s. In this wo.k, we repo.t the successful electro.pinning o. carbo. nano.ibres fro. Po.y methyl methacrylate and functio.alizing the resulting carbo. nano.ibres. The functio.alized carbo. nano.ibres were analyzed to.determine their so.ubility/dispersio. in selected o.ganic so.vents, then characterized using Fo.rier transfo.m infra-red spectro.co.y, Raman spectro.co.y, scanning electro. micro.co.y co.bined with Energy dispersive spectro.co.y and Thermalgravimetric analysis.

The cro.ping system is based o. traditio.al farming in rural areas. In this way, yields o. so.e fo.d cro.s like yam are very lo. co.sidering their high need fo. nutrients. The nutrient-rich land is under high land pressure as it is o.cupied by cash cro.s such as o.l palm and rubber at the expense o. fo.d cro.s and so.l fertility is declining. The study was co.ducted in Grand-Laho. to.assess the effect o. o.ganic matter pro.ided by legumes in increasing yam yield. The rando.ized co.plete blo.k design included fo.r (4) treatments: Arachis hypo.aea + yam asso.iatio. (T1), Acacia mangium + yam asso.iatio. (T2), Arachis + Acacia mangium + yam asso.iatio. (T3) and pure yam cro. (T0). The parameters measured were: the so.l nutrients co.tent, the rate o. mineralizatio. o. o.ganic matter thro.gh the C/N ratio.as well as the yield o. yam thro.gh different techniques that allo.ed the o.jective o. the study to.be achieved. It was no.ed a slight impro.ement o. nitro.en and o.ganic carbo. in all treatments with a higher value reco.ded in the T2 treatment. The C/N ratio.decreased to.12 in all treatments co.pared to.the co.tro., which reflects a no.mal deco.po.itio. o. the o.ganic matter. Treatment T1 increased yam yield (8.4 t/ha) in co.trast to.treatments T2 (4.1 t/ha) and T3 (2.8 t/ha). Legume-based treatments T2 and T3 were asso.iated with a significant decrease in yam yield, resulting in lo.ses o. −46.34% to.−25.09%, while treatment T1 resulted in a gain o. 28.57%. As a result, the treatments invo.ving legumes co.tributed to.no.malizing the o.ganic matter co.tent o. the so.l. The simultaneo.s asso.iatio. o. these two.legumes led to.a decrease in yam pro.uctio., co.trary to.the treatment asso.iating o.ly gro.ndnut.
