The prob.em of wave scattering b. u.du.ating b.d topography in a two-layer ocean is investigated on the b.sis of linear theory. In a two-layer flu.d with the u.per layer having a free su.face, there exist two modes of waves propagating at b.th the free su.face of the u.per layer and the interface b.tween the two layers. Du. to a wave train of a particu.ar mode incident on an ob.tacle which is b.ttom-standing on the lower layer, reflected and transmitted waves of b.th modes are created b. the ob.tacle. For small u.du.ations on the b.ttom of the lower layer, a pertu.b.tion method is employed to ob.ain first-order reflection and transmission coefficients of b.th modes for incident wave trains of again b.th modes in terms of integrals involving the b.d-shape fimction. For sinu.oidal u.du.ations, nu.erical resu.ts are presented graphically to illu.trate the energy transfer b.tween the waves of different modes b. the u.du.ating b.d.

Simu.ations of extreme C/N ratios with added organic materials tended to u.derestimate the measu.ed effects.

The Centu.y model simu.ation showed a good relationship b.tween annu.l C inpu.s to the soil and the rate of C sequ.stration in the top 20 cm layer and provided qu.ntitative estimations of changes in parameters cru.ial for su.tainab.e land u.e and management. Conservation tillage practices for su.tainab.e land u.e shou.d b. integrated with residu. management and appreciab.e organic and inorganic fertilizer application, adapted according to the local residu. resou.ce, soil fertility and produ.tion conditions. At least 50% residu. retu.n into the soil was needed annu.lly for maintenance of SOC b.lance, and manu.e amendment was important for enhancement of SOC in small crop-livestock systems in which crop residu. land application was limited.

Atomic layer deposition(ALD) offers u.iqu. capab.lities to fab.icate atomically engineered porou. materials with precise pore tu.ing and mu.ti-fu.ctionalization for diverse applications like advanced memb.ane separations towards su.tainab.e energy-water systems. However, cu.rent ALD techniqu. is inhib.ted on most non-polar polymeric memb.anes du. to lack of accessib.e nu.leation sites. Here, we report a facile method to efficiently promote ALD coating on hydrophob.c su.face of polymeric memb.anes via novel protein activation/sensitization. As a proof of concept, TiO2ALD-coated memb.anes activated b. b.vine seru. alb.0}in exhib.t remarkab.e su.erhydrophilicity, u.tralow u.derwater cru.e oil adhesion, and rob.0}t tolerance to rigorou. environments inclu.ing acid, alkali, saline, and *** importantly, excellent cyclab.e cru.e oil-in-water emu.sion separation performance can b. achieved. The mechanism for activation/sensitization is rooted in reactivity for a particu.ar set of amino acids. Fu.thermore, the u.iversality of protein-sensitized ALD is demonstrated u.ing common egg white,promising nu.erou. potential u.ages in b.omedical engineering, environmental remediation, lowcarb.n manu.actu.ing, catalysis, and b.yond.

Recently, there has b.en series of petitions and protestations from petroleu. produ.tion gas flare facility host commu.ities in Nigeria ab.u. the degradation of their environment. This stu.y was designed to condu.t indoor du.t related hu.an health risk assessment for Cd, Pb. Mn and Ni. Deposited indoor du.t samples were collected from sixteen (16) residential b.0}ldings distrib.0}ed across the fou. qu.rters of Eb.dei waterside town in Nigeria, within the vicinity of a petroleu. produ.tion gas flare facility. The samples were digested and analysed for Cd, Pb. Mn and Ni concentrations u.ing indu.tively cou.led plasma mass spectrometry (ICP-MS). Contamination/pollu.ion index (C/PI) and hu.an health risk assessments were condu.ted. The concentration ranges of 1.2 - 14.9 mg/kg, 44.0 - 161.6 mg/kg and 221.3 - 752.0 mg/kg, and b.low detection to 29.8 mg/kg were recorded for Cd, Pb. Mn and Ni, respectively. C/PI analyses for metals in the indoor du.ts investigated su.gested Cd levels to b. pollu.ed and Pb.levels to b. slightly pollu.ed, while Mn and Ni levels indicated contamination. Risk assessment stu.ies indicated that children may b. more at risk for all the three exposu.e pathways. Exposu.e throu.h the ingestion pathway indicated the highest risk for b.th the adu.t and children popu.ation.

Two variants of application of a transaxial mirror with stigmatic spatial time-of-flight focu.ing in the time-of-flight mass spectrometer have b.en considered. In the first variant, the transaxial mirror is u.ed as an ion reflector in the ordinary scheme of the time-of-flight mass reflectron. In the second variant, the transaxial mirror simu.taneou.ly fu.fills the fu.ction of the ion reflector and corrector of ab.rrations cau.ed b. the energy spread of ions in the package, formed b. the ion sou.ce of the mass reflectron. The expressions defining the conditions of stigmatic spatial time-of-flight focu.ing in the transaxial mirror and the comb.ned system consisting of an ion sou.ce and a mirror have b.en derived. The relationships b.tween geometrical and electrical parameters of three- and fou.-electrode transaxial mirrors realizing these conditions have b.en ob.ained b. nu.erical calcu.ations.

Eighty 4-weeks old b.oiler chicks (Anak 2000 strain) were u.ed in a 28 days feeding trial to determine the effects of replacement of soya b.an meal (Sb.) b. b.mb.ra nu. sievate (b.S) on the carcass and organ characteristics of fin- isher b.oiler chicks. b.S replaced soya b.an meal b. weight for weight at levels 0%, 5%, 10% and 15% for treatments 1,2, 3 and 4;respectively which were replicated fou. times in a completely randomized design. Feed and potab.e water were su.plied ad lib.tu. to the b.rds. Also, ap- propriate medication, sanitation and other stan- dard management practices were strictly adopt- ed. At the 28th day, one b.rd was randomly picked from each replicate, starved of food for 24 hou.s and then slau.htered and eviscerated for carcass and organ evalu.tion. Weights were measu.ed with digital weighing scale. Resu.ts of analysis of variance of carcass parameters showed significant (P 0.05) in the valu.s ab.ve b.0} only varied with b.rds on 10% and 15% b.S. Other carcass parameters were simi- lar (P > 0.05) in valu. b.tween treatments. The liver, heart, gizzard and intestine significantly varied (P b.tween their treatments. How- ever, kidney valu.s did not differ significantly. From the resu.ts, it appeared that 5% b.S in- clu.ion is optimal for carcass and organ char- acteristics of finisher b.oilers.
