65 chickens (layer, bro.ler and.co.kerel) fro. d.fferent farms within Awka metro.o.is and.its enviro.s were purchased. pro.essed.and.analyzed.fo. the levels o. heavy metals (Pb, As, Cd. Ni, Cr, Hg, V and.Cu) in the internal o.gans (muscle, gizzard. liver and.kid.ey) o. the chickens using flame ato.ic abso.ptio. spectro.eter after nitric/perchlo.ic acid.d.gestio.. The ranges o. mean co.centratio.s o. the metals in the internal o.gans o. the chickens in mg/g were Pb;(0.046 - 0.478) As;(0.053 - 0.318), Cd.(0.027 - 0.649), Cr;(0.045 - 0.234), Hg;(0.052 - 0.740), Ni;(0.038 - 0.534), V;(0.037 - 0.053), and.Cu;(0.146 - 0.445). Abo.t 10% - 40% o. Pb, Cd.and.Hg exceed.d.the permissible level o. 0.5 ppm set fo. these metals in the liver and.kid.ey o. the chickens. Ano.a analysis revealed.significance o. the heavy metals in the internal o.gans o. the chickens at p < 0.05.

The need.to.mitigate d.wntime in marine vessels arising from propulsion system failures has led ship operating companies to devote enormous resources for research based solutions. This paper applied duration models to determine failure probabilities of shaft and gearbox systems in service boats. Using dockyard’s event history data on boat repairs and maintenance, we applied Kaplan Meier hazard and survival curves to analyse probability of failure of shaft and gearbox systems in supply, crew and tug boats. We found that average time to shaft and gearbox failure was 8.33, 5.23 and 5.21 months for tug, supply and crew boats respectively. The hazard plots however, showed that supply boats had higher probability of failure than crew boats and then tug boats in that order. Further analysis using Cox regression model showed that the boats’ shaft and gearbox system failures were significantly affected by level of lubrication oil, stress corrosion cracking and impacts on the propulsion system’s components. The paper proposes that design of maintenance

AIM: To.stud. the brain-gut interactio. and.the effect o. behavio.al o. psychiatric co.d.tio.s o. irritable bo.el synd.o.e (IBS) in an African po.ulatio.. METHo.0}: IBS was d.agno.ed.using the Ro.e Ⅱ d.agno.tic criteria. The entry o. each patient was co.firmed.fo.lo.ing d.tailed.explanatio.s o. the questio.s. Fo.r hund.ed.and.eighteen patients were stud.ed. Subjects satisfying the Ro.e Ⅱ criteria fo. IBS were physically examined.and.sto.l micro.co.y was d.ne to.id.ntify the presence o. “alarm facto.s”. d.pressio. was d.agno.ed.using the sympto.-check list ad.pted.fro. the Research d.agno.tic Criteria (d.M-Ⅳ) o. the American Psychiatric Asso.iatio.. RESULTS: Seventy-five (56.8%) o. the 132 IBS patients were d.pressed.whereas o.ly 54 (20.1%) o. the 268 no.-IBS patients were d.pressed. There was a significant relatio.ship between IBS and.d.pressio. (χ2 = 54.29, o.0}s ratio.= 5.21, 56.8 ± 8.4 vs 20.1 ± 5.2, P = 0.001). Even tho.gh co.stipatio. pred.minant IBS patients were mo.e likely to.be d.pressed. no.significant relatio.ship was fo.nd.between the subtype o. IBS and.d.pressio. (χ2 = 0.02, o. = 0.95, P = 0.68). Co.CLUSIo.: IBS is significantly asso.iated.with majo. d.pressio. but no. gend.r and.bo.el subtypes o. the patients. Patients with IBS need.to.be evaluated.fo. d.pressio. d.e to.the highly significant relatio.ship between the two.co.d.tio.s.

The leaf length ranged.fro. 35.6 ± 7.70 cm (“ko.huo.) to.49.9 ± 3.55 cm (“o.erio.o.i”). Petio.e length o. “o.erio.o.i” was the highest (63.3 ± 3.83 cm), whereas the least was Co.o.asia esculenta var. antiquo.um (26.67 ± 2.20 cm). The co.m length ranged.fro. 4.10 ± 0.10 cm (Co.o.asia esculenta var. antiquo.um) to.8.60 ± 0.35 cm (“o.erio.o.i”), while the co.mel length ranged.fro. 3.70 ± 0.96 cm (Co.o.asia esculenta var. antiquo.um) to.7.03 ± 0.36 cm (“o.erio.o.i”).
