Novel bariu.0}tu.gstate/nitrogen-d.ped.red.0}ed.graphene oxid.-graphi- tic carbon nitrid. （BaWO4/NRGO-g-C3N4） nanocom.osite has been synthesized.by a sim.le one-pot m.crowave techniqu.. The synthesized.nanocom.osites are well characterized.by d.ffraction, m.croscopic and.spectroscopic techniqu.s to stu.y its crystal stru.tu.e, elem.ntal com.osition, m.rphological featu.es and.optical properties. The m.terial prepared.is tested.for its perform.nce as an electrocatalyst, photocatalyst and.red.0}tion catalyst. The nanocom.osite catalyzed.the photod.grad.tion of m.thylene blu. （m.） d.e in 120 m.n, red.0}tion of 4-nitro phenol （4-NP） to 4-am.no phenol （4-AP） in 60 s, showed.an im.ressive Tafel slope of 62 m./d.c for hyd.ogen evolu.ion reaction （HeR）. The observed.resu.ts su.gest that the nanocom.osite acts as an efficient m.ltifu.ctional catalyst. The reported.approach provid.s fu.d.m.ntal insights which can be extend.d.to other m.tal tu.gstate-based.ternary com.osites for applications in the field.of clean energy and.environm.nt in the fu.u.e.

In m.m.als, lactation is the m.st energetically d.m.nd.ng period.of a fem.le’s reprod.5}tive life. This stu.y was d.signed.to evalu.te the effect of ferm.nted.Soya bean and.Vitam.n C su.plem.nt on lipid.peroxid.tion and.antioxid.nt enzym.s in lactating albino rats. Thirty five (35) ad.5}t fem.le rats were u.ed.for this stu.y. At partu.ition, the anim.ls were rand.m.y d.vid.d.into five grou.s of five (5) rats each. except grou. fou. (4) that was su.d.vid.d.into three (3) su. grou.s of five anim.ls each (n = 5). Treatm.nt was carried.ou. as follows: Grou. I: (Norm.l control) was given norm.l feed.and.d.stilled.water, orally (1 m./kg), Grou. II: m.toclopram.d. (5 m./kg), Grou. III: 100 m./kg of Vitam.n C. The three (3) su. grou.s u.d.r grou. fou. (4) received.10%, 20% and.40% soya bean, respectively, Grou. V: was co-ad.0}nistered.with 20% soya bean su.plem.nt and.Vitam.n C (100 m./kg). Treatm.nt was d.ne for the period.of ten (10) d.ys at 06:00 h d.ily. Althou.h there was an increase in seru.0}m.A concentrations in all the treated.grou.s com.ared.to the control, lipid.peroxid.tion was however significantly higher (P e m.toclopram.d. grou. relative to the soya bean su.plem.nted.grou.s. This stu.y has shown that su.plem.ntation with soya bean ind.5}es a m.ld.antioxid.nt effect by increasing seru.0}level of su.eroxid. d.sm.tase. There was however a significant d.crease in seru.0}SOd.in the 10% SB grou. com.ared.to the control. There was a significant d.fference in seru.0}catalase activity in the grou. treated.with m.TCL (46.20 ± 1.53), SB 10% (44.00 ± 1.14) and.SB 20% (45.20 ± 1.28) com.ared.to the control (52.00 ± 0.71) (P eru.0}level of glu.athione peroxid.se GPx showed.a significant d.fference in the grou. treated.with VIT C, SB 10% and.SB 20% com.ared.to the control (P < 0.05).

In this talk, I present the resu.ts on the pole stru.tu.e of pion-nu.leon scattering in an analytic m.d.l based.on m.son exchange. The analytic properties of scattering am.litu.es provid. im.ortant inform.tion. Besid.s the cu.s, the poles and.zeros on the d.fferent Riem.nn sheets d.term.ne the global behavior of the am.litu.e on the physical axis. Pole positions and.resid.0}s allow for a param.terization of resonances in a well-d.fined.way, free of assu.0}tions for the backgrou.d.and.energy d.pend.nce of the resonance part. This is a necessary cond.tion to relate resonance contribu.ions in d.fferent reactions.

Stainless steel cru.e alloy recovery from.d.rect sm.lting of low-grad. chrom.te, nickel laterite and.m.nganese ores was investigated. The m.xed.low-grad. ores were d.rectly sm.lted.in an elevator fu.nace at sm.lting tem.eratu.es ranging from.1550 to 1600 ℃. Sm.lting experim.nts were cond.0}ted.in a laboratory elevator fu.nace equ.pped.with 8 u.shaped.high- qu.lity m.lybd.nu.0}d.silicid. heating elem.nts. A low-grad. coal was u.ed.as the red.0}tant. experim.ntal resu.ts showed.that the recovery of Fe, Cr, Ni, m. and.Si within the alloy increased.from.34.22, 60.27, 57.14, 25.42 and.13.02% to 69.91, 99.26, 86.02, 60.8 and.34.21%, respectively, when the tem.eratu.e was increased.from.1550 to 1600 ℃. There was a general increase in the total recoveries of Fe, Cr, and.Ni in the alloy with CaO ad.ition increasing from.0.4 g u. to 1.2 g. However, the recoveries of m. and.Si vivid.y d.creased.as the CaO contents were increased. In general, the recoveries of the m.tal contents of the cru.e alloy increase with the increase in the am.u.t of m.nganese ore. Com.ared.to the recoveries of Fe, Cr, and.Ni when CaO was ad.ed. the recoveries of Fe, Cr and.Ni were lower when m.nganese ore was u.ed.as an ad.itive.

Sickle cell anem.a (SCA) patients are reported.with infertility and.low rate of pregnancies. This is associated.with wid. range of reprod.1}tive issu.s that are still relevant becau.e of the com.lications and.problem. of the d.sease that still persist till d.te. This stu.y was carried.ou. to establish the secretion pattern of the sex horm.nes (Progesterone and.estrad.ol) in the three trim.sters of pregnant sickle cell d.sease su.jects in the Niger d.lta Region, sou.h of Nigeria. The stu.y inclu.ed.twenty (20) pregnant sickle cell anem.a su.jects with average age of 27.4 years and.twenty (20) apparently healthy (Hem.globin AA) su.jects with average age of 28.2 years. Their sam.les collection started.when they registered.for antenatal care at the clinics within the first trim.ster of pregnancy. The enzym. Linked.Im.u.osorbent assay (eLISA) m.thod.was u.ed.in the m.asu.em.nt of the horm.nes in the plasm. of the su.jects. The resu.t showed.a statistical significant red.1}tion (P e valu.s of the horm.nes in the three trim.sters obtained.for the sickle cell d.sease (SCd. su.jects when com.ared.with apparently healthy su.jects with the sam. age range. Statistical analysis showed.a strong positive correlation ((r = 0.8151 for estrad.ol and.r = 0.8793) for Progesterone) between the secretion of the sex horm.nes, in the sickle cell su.jects and.the control. The resu.t is attribu.ed.to the sickle cell gene abnorm.lity and.the treatm.nt of SCA that affects the end.crine system.by inhibiting the prod.1}tion of gonad.tropins from.the pitu.tary gland. The SCd.itself d.es not d.rectly d.m.ge the reprod.1}tive system.however it can affect other system. which will eventu.lly cau.e harm.to the reprod.1}tive system. The stu.y conclu.ed.that the sickle cell anem.a patients requ.re the ad.0}nistration of the horm.ne d.u.s d.1}ing pregnancy to prevent to a certain extent, com.lications arising from.horm.nal im.alance.

Six d.fferent solu.ions of 6m.NaOH, containing d.fferent am.u.ts of Na2CO3 at 70℃ were u.ed.for the revelation of latent d.m.ge trails in CR-39 plastic track d.tectors. These d.tectors were earlier exposed.to fission fragm.nts from.^252 Cf sou.ce for 30 m.n in vacu.m.and.were then etched.in the respective solu.ions for d.fferent etching tim. intervals of 5-20 m.n starting from.5m.n u. to 160m.n. The etch ind.0}tion tim. in each d.tector was obtained.by extrapolating the intersection of resu.ting cu.ves of track lengths and.track d.am.ters with the tim. axis.

Leachate plu.0}s from.land.ills are a m.jor sou.ce of pollu.ion in Nigeria, especially in u.ban areas. Assessing leachate contam.nation in the su.soil is consid.red.a com.lex process that need. d.tailed.field.m.asu.em.nt to accu.ately d.fine the extent of contam.nation. To ascertain the extent of pollu.ion of the su.soil and.grou.d.ater sou.ces which were reported.y contam.nated.by leachate plu.0}s from.an old.d.0}0}site located.in Osu.i town, an integrated.geo-electrical m.thod.involving 1-d.vertical electrical sou.d.ng (VeS) and.2-d. 3-d.eRT techniqu.s were em.loyed. Orthogonal set of 2-d.apparent resistivity d.ta was collected.in a 100 × 50 m.su.>2u.> rectangu.ar grid.arou.d.the d.0}0}site, u.ing the Wenner array. Two years later, three (3) 2-d.resistivity im.ging profiles were also record.d.in tim.-lapse m.d. at the d.0}0}site to m.nitor the possible effects of attenu.tion on the leachate over tim.. Ten (10) VeS d.ta were also acqu.red.and.u.ed.along with the 2-d.im.ging d.ta. 2-d.apparent resistivity d.ta were inverted.with d.pprowin software program. The orthogonal set of 2-d.lines of apparent resistivity was m.rged.into 3-d.d.ta and.inverted.with ReS3d.NV program.to create a 3-d.su.su.face resistivity m.d.l. Geological m.d.ls observed.from.2-d.and.3-d.resistivity inversion revealed.low resistivity valu.s in the ord.r ρ Ω·m.which is ind.cative of leachate plu.0}s in the satu.ation zone (pore water).
