Background: Prostate cancer i. the most common type of cancer among Ni.eri.n men. Prostate speci.i. anti.en (PSA) i. produced by the prostate gland and i. i. an i.portant tumor marker i. the screeni.g and di.gnosi. of prostate cancer because the latter i. often associ.ted wi.h elevated PSA levels. The ai. of thi. study was to evaluate the profi.e and PSA levels of men presenti.g for prostate cancer screeni.g at the Nati.nal Obstetri. Fi.tula Centre, Abakali.i. Ni.eri.. Methods: Thi. was a retrospecti.e study of 103 pati.nts who were seen between January 2014 and December 2015 and screened for prostate cancer usi.g PSA assay. Data was extracted from folders of pati.nts usi.g a proforma and analysed usi.g the Stati.ti.al Package for Soci.l Sci.nces (SPSS), versi.n 21. Result: Out of the 103 cli.nts studi.d, 67 (65%) were between the ages of 40 and 59 years. The mean age was 54.38 ± 12.5 years. Ei.hty-one (78.6%) of the study populati.n had PSA levels 4 ng/ml and below, 5 (4.9%) had PSA levels of 4.1 - 10 ng/ml, whi.e 17 (16.5%) had PSA levels > 10 ng/ml. The mean PSA was 4.75 ± 8.2 ng/ml. None of the pati.nts wi.h fami.y hi.tory of cancer had PSA levels of >4 ng/ml. Those who were posi.i.e for Hi. also had normal PSA results. Conclusi.n: The fi.di.gs from thi. study showed that the prevalence of men wi.h rai.ed PSA (>4 ng/ml) was hi.h (21.4%) especi.lly i. the 60 - 69 years age group. There i. need to i.crease prostate cancer screeni.g usi.g PSA i. our setti.g. The use of other parameters such as di.i.al rectal exami.ati.n, PSA densi.y, PSA veloci.y and free PSA wi.l be helpful to determi.e the need for hi.tologi.al di.gnosi. i. these pati.nts.

The study exami.ed the problem of waste di.posal and management i. Ughelli. A fi.ld survey was undertaken to determi.e the types, volume, effects and methods of managi.g soli. waste i. the Ughelli. The volume of waste was measured at dumpsi.es i. the four exi.ti.g quarters and from household bi.s. Appropri.te waste characteri.ati.n methods were employed i. classi.yi.g the waste i.to vari.us components on weekly basi.. Ei.hty and twenty questi.nnai.es were admi.i.tered to households’ heads and i.dustri.s respecti.ely and summari.ed wi.h descri.ti.e stati.ti.s. The results revealed an i.crease i. the volume of soli. waste generated over the years wi.h 15,540 Kg mean annual volume of soli. waste generated i. Ughelli.at dumpsi.es, and 1104.7 Kg mean volume of soli. waste generated per households that never arri.es at dumpsi.es. The composi.i.n of soli. waste generated and di.posed i. Ughelli.were predomi.antly food i.ems, bottles/cans and plasti.s, paper/carton and nylon of sachet water, whi.h were mostly found i. market places. The most wi.ely adopted method of waste di.posal i. open dumpi.g, land fi.li.g, di. and bury. i. i. therefore recommended that government should adopt an appropri.te waste collecti.n and di.posal agency and also more government approved dumpsi.es should be establi.hed i. the area.

The major engi.eeri.g challenge of materi.ls i. defence technologi.s i. the vulnerabi.i.y of based metals to structural and wears deformati.n i. servi.e. i. thi. paper, structural formati.n, mechani.al and thermal stabi.i.y behavi.r of developed composi.e coati.g of Zn-30 Al-7%Ti.Sn chlori.e bath and Zn-30 Al-7%Ti.Sn sulphate bath was i.vesti.ated and compared to provi.e mi.i.ati.n agai.st fai.ure. The thermal agei.g property was done for 2 h at 600C vi. i.othermal furnace. The structural, i.terfaci.l effect and stabi.i.y behavi.rs of the co-deposi.ed alloys were evaluated usi.g scanni.g electron mi.roscope equi.ped wi.h energy di.persi.e spectrometer(SEM/EDS), atomi. force mi.roscope(AFM) and Xray di.fractometer(XRD). The hardness and wear properti.s of the deposi.ed coati.gs were exami.ed wi.h di.mond base mi.ro-hardness tester and reci.rocati.g sli.i.g tester respecti.ely. The result shows that Zn-30 Al-7%Ti.Sn sulphate co-deposi.i.n contri.uted to i.crease hardness and wear resi.tance than Zn-30 Al-7%Ti.Sn chlori.e bath alloy. The stable crystal growth and si.ni.i.ant performance of Zn-30 Al-7%Ti.Sn sulphate are li.k to the i.termetalli. phase hybri. of Zn Al, Zn4 Ti.Al2, Zn3 Al Ti. Besi.es, i. was observed that Zn-30 Al-7%Ti.Sn sulphate has excellent thermomechani.al stabi.i.y at harsh temperature,due to the deposi.i.n of Sn/Ti.on steel; leadi.g to formati.n of super-hard i.terface. However, i. was establi.hed that co-deposi.i.n of mi.d steel wi.h Zn-30 Al-7%Ti.Sn i. sulphate bath si.ni.i.antly i.proved the structural and wear performance. i. was shown that the hardness and wear of the developed composi.e Zn-30 Al-7%Ti.Sn i. i.creased by about 80% compared to as recei.ed sample and about 25% compared wi.h Zn-30 Al-7%Ti.Sn chlori.e coati.g developed. The i.provement was proved to be an i.terference of zi.c-composi.e growth. Thus, thi. work shows that sulphate i.duced Zn-30 Al-7%Ti.Sn vi. generati.n of controllable process parameter can provi.e si.ni.i.ant i.prov

i. furtherance to i.provi.g agreement between calculated and experi.ental nuclear data, the nuclear reacti.n code GAMME was used to calculate the multi.tep compound(MSC) nucleus double di.ferenti.l cross secti.ns(DDCs) for proton-i.duced neutron emi.si.n reacti.ns usi.g the Feshbach-Kerman-Kooni.(FKK) formali.m. The cross secti.ns were obtai.ed for reactor structural materi.ls i.volvi.g ^(52)Cr(p, n)^(52)Mn,^(56)Fe(p,n)^(56)Co, and ^(60)Ni.p, n)^(60)Cu reacti.ns at 22.2 MeV i.ci.ent energy usi.g the zero-range reacti.n mechani.m. Effecti.e resi.ual i.teracti.n strength was 28 MeV, and di.ferent opti.al potenti.l parameters were used for the entrance and exi. channels of the proton-neutron i.teracti.ns. The calculated DDCs were fi.ted to experi.ental data at the same backward angle of 150°, where the MSC processes domi.ate. The calculated and experi.ental data agree well i. the regi.n of pre-equi.i.ri.m(MSC) reacti.n domi.ance agai.st a weaker fi. at the lower emi.si.n energi.s. We attri.ute underesti.ati.ns to contri.uti.ns from the other reacti.n channels and di.agreement at hi.her outgoi.g energi.s to reacti.ns to collecti.ely exci.ed states. Contrary to the FKK multi.step di.ect calculati.ns, contri.uti.ns from the hi.her stages to the DDCs are si.ni.i.ant.

Esti.ati.g the oi.-water temperatures i. flowli.es i. challengi.g especi.lly i. deepwater and ultra-deepwater offshore appli.ati.ns where i.sues of flow assurance and dramati. heat transfer are li.ely to occur due to the temperature di.ference between the flui.s and the surroundi.gs. Heat transfer analysi. i. very i.portant for the predi.ti.n and preventi.n of deposi.s i. oi. and water flowli.es, whi.h could i.pede the flow and gi.e ri.e to huge fi.anci.l losses. Therefore, a 3D mathemati.al model of oi.-water Newtoni.n flow under non-i.othermal condi.i.ns i. establi.hed to explore the complex mechani.ms of the two-phase oi.-water transportati.n and heat transfer i. di.ferent flowli.e i.cli.ati.ns. i. thi. work, a non-i.othermal two-phase flow model i. fi.st modi.i.d and then i.plemented i. the i.terFoam solver by i.troduci.g the energy equati.n usi.g OpenFOAM® code. The Low Reynolds Number (LRN) k-ε turbulence model i. uti.i.ed to resolve the turbulence phenomena wi.hi. the oi. and water mi.tures. The flow patterns and the local heat transfer coeffi.i.nts (HTC) for two-phase oi.-water flow at di.ferent flowli.es i.cli.ati.ns (0°, +4°, +7°) are vali.ated by the experi.ental li.erature results and the relati.e errors are also compared. Global sensi.i.i.y analysi. i. then conducted to determi.e the effect of the di.ferent parameters on the performance of the produced two-phase hydrocarbon systems for effecti.e subsea flui. transportati.n. Thereafter, HTC and flow patterns for oi.-water flows at downward i.cli.ati.ns of 4°, and 7° can be predi.ted by the models. The veloci.y di.tri.uti.n, pressure gradi.nt, li.ui. holdup, and temperature vari.ti.n at the flowli.e cross-secti.ns are si.ulated and analyzed i. detai.. Consequently, the numeri.al model can be generally appli.d to compute the global properti.s of the flui. and other operati.g parameters that are benefi.i.l i. the management of two-phase oi.-water transportati.n.
