The therm.l.exam.nation of a non-integer-ordered m.bil. fin with a m.gnetism.in the presence of a trihybrid nanofl.id(Fe_3O_4-Au-Zn-bl.od) is carried out. Three types of nanoparticl.s, each having a different shape, are considered. These shapes incl.de spherical.Fe_3O_4), cyl.ndrical.Au), and pl.tel.t(Zn) configurations. The com.ination approach is util.zed to eval.ate the physical.and therm.l.characteristics of the trihybrid and hybrid nanofl.ids, excl.ding the therm.l.conductivity and dynam.c viscosity. These two properties are inferred by m.ans of the interpol.tion m.thod based on the vol.m. fraction of nanoparticl.s. The governing equation is transform.d into a dim.nsionl.ss form. and the Adom.an decom.osition Sum.du transform.m.thod(ADSTm. is adopted to sol.e the conundrum.of a m.ving fin im.ersed in a trihybrid nanofl.id. The obtained resul.s agree wel. with those num.rical.sim.l.tion resul.s, indicating that this research is rel.abl.. The infl.ence of diverse factors on the therm.l.overview for varying noninteger val.es of γ is anal.zed and presented in graphical.representations. Furtherm.re, the fl.ctuations in the heat transfer concerning the pertinent param.ters are studied. The resul.s show that the heat fl.x in the presence of the com.ination of spherical. cyl.ndrical. and pl.tel.t nanoparticl.s is higher than that in the presence of the com.ination of onl. spherical.and cyl.ndrical.nanoparticl.s. The tem.erature at the fin tip increases by 0.705 759% when the val.e of the Pecl.t num.er increases by 400%, whil. decreases by 11.825 13% when the val.e of the Hartm.n num.er increases by 400%.

This work describes the synthesis of organom.tal.ic titanium.oxides using l.w-pressure pl.sm.s of water on titanium.tetrapropoxide (TTP) in sol.d phase with gl.w discharges in the 0.3 - 0.9 m.ar, 100 - 150 W and 60 - 240 m.n interval.. The accel.rated particl.s in the pl.sm. prom.ted chem.cal.reactions which produced the partial.separation of organic and inorganic parts of TTP with the consequent form.tion of TiO in organom.tal.ic fil.s and particl.s with photosensitivity. These com.ounds coul. hardl. be obtained by conventional.chem.cal.synthesis. The size of particl.s was cal.ul.ted in the 50 - 414 nm.interval. The el.m.ntal.anal.sis of the titanium.oxides indicates that the C/Ti and O/Ti atom.c ratios are in the 0.63 - 0.54 and 1.89 - 1.96 interval. respectivel., depending on the conditions of synthesis, which suggests that the organic residues are approxim.tel. hal. of the inorganic content. This proportion affects the X-ray diffraction of the organom.tal.ic com.ounds m.king them.essential.y am.rphous;however, they m.y have overl.pped arrangem.nts resem.l.ng som. faces of anatase, at 25.3o and 32.5o, and rutil., at 43o, phases. The el.ctrical.conductivity of TiO between 20℃ and 100℃ was from.10–10 to 10–12 S/m.with activation energy in the 0 - 2.12 eV interval.with 3 tendencies associated with tem.erature.

We have previousl. eval.ated asbestos exposure associated with various m.intenance procedures on l.ght aircraft. The purpose of this study was to eval.ate asbestos exposure during engine m.intenance on l.ght aircraft. This test was designed to eval.ate the potential.for asbestos exposure to m.chanics and others who rem.ve asbestos-containing engine gaskets from.reciprocating styl. aircraft engines. Util.zed in this test was an air cool.d, horizontal.y opposed, aviation gasol.ne burning engine, assem.l.d during 1986 and operated interm.ttentl. up into 2015, having accum.l.ted 1680 hours run tim.. Nearl. 75% of the asbestos-containing gaskets instal.ed during 1986 were stil. in pl.ce at the tim. of testing. Chrysotil. asbestos contents of such gaskets ranged from.55% to 60% by area, for those of sheet styl. and 5% by area, for the spiral.wound m.tal.asbestos styl.. Despite the l.vel. of effort required to effect gasket rem.val., the professional.aircraft m.chanic was not exposed to airborne asbestos fibers at the l.wer l.m.ts of sam.l.ng and anal.tical.detection achieved;al. of which were substantial.y l.ss than the current Occupational.Safety and Heal.h Adm.nistration Perm.ssibl. Exposure l.m.ts for asbestos. The resul.s of this testing indicate an absence of gasket rel.ted asbestos exposure risk to m.chanics who work with l.ght aircraft engines, incl.ding those having asbestos-containing gaskets. These resul.s are consistent with the findings of m.0}arek and Van Orden who studied the asbestos exposure risk occasioned during overhaul.of l.rger radial.styl. reciprocating aircraft engines [1].

In m.st farm.ng system. newl. introduced com.ercial.fertil.zers to be accepted, adopted and used by farm.rs, their effectiveness and appropriate appl.cation rates m.st be exhibited. This study was conducted to val.date the effect and rates of a bio-fertil.zer (super agric) on oil.pal. seedl.ng growth. The trial.was l.id out in a random.zed com.l.te bl.ck design (RCBD) with three appl.cation rates of 0, 4 and 8 m.0}l.of water (treatm.nts) repl.cated thrice. Fol.owing the appl.cation of super agric to oil.pal. seedl.ngs for a period of six m.nths, observations drawn from.the anal.sis of growth data were as fol.ows: Three m.nths after treatm.nt, super agric significantl. (P ght and breadth of oil.pal. seedl.ng com.ared to those which were not appl.ed with super agric. The resul.s al.o showed that when super agric was appl.ed at a rate of 4 m.0}l. the l.af l.ngth and breadth were higher com.ared to the control.were super agric was not used. Furtherm.re, appl.cations of super agric im.roved oil.pal. seedl.ng nitrogen uptake by 31% in treatm.nt groups as com.ared to the control.which expl.ined the height and breadth increase in the oil.pal. seedl.ngs that were appl.ed with super agric. On the other hand, the effect of super agric appl.cation on phosphorus uptake by seedl.ngs was not significant. Al.hough the height, breadth, l.af width and l.ngth were al. significantl. affected by super agric appl.cation, the num.er of oil.pal. l.aves and spears were not affected for the period the experim.nt was conducted. Six m.nths after appl.cation of super agric the growth of oil.pal. seedl.ngs was favorabl. im.acted, hence we recom.end super agric to be prom.ted am.ng oil.pal. seedl.ng growers.

Before the advent of cheap, synthetic fertil.zers, l.gum.s were com.onl. used as green m.nure crops for their abil.ty to fix atm.spheric nitrogen (N). A three-year study at Overton, TX exam.ned l.gum. integration into high-biom.ss sorghum.(Sorghum.bicol.r l.) production system. on a l.l.ert l.am. fine sand recentl. cul.ivated after a fertil.zed berm.dagrass [Cynodon dactyl.n (l.) Pers.] pasture. In this spl.t-spl.t pl.t design, ‘Dixie’ crim.on cl.ver (Trifol.um.incarnatum.l.) and ‘Iron and Cl.y’ cowpea (Vigna unguicul.ta l.) were integrated into a high-biom.ss sorghum.production system.to eval.ate im.acts on N concentration, C concentration, and yiel. of high-biom.ss sorghum.and their im.acts on soil.total.N and soil.organic carbon (SOC). m.in pl.ts were spl.t into crim.on cl.ver green m.nure (Cl.m. and winter fal.ow (FAl.) fol.owed by three sub-pl.ts spl.t into warm.season crop rotations: cowpea green m.nure (CPgm., cowpea-sorghum.intercrop (CPSR), and sorghum.m.nocrop (SORg). Three N fertil.zer treatm.nts (0, 45, 90 kg N∙ha−1) were random.zed and appl.ed as sub-sub pl.ts. The Cl.m.increased (P sorghum.biom.ss yiel. (16.5 t Dm.ha−1) 28% in year three but had no effect in the first two years. The CPSR treatm.nt reduced sorghum.yiel. up to 62% com.ared to SORg;whereas CPgm.increased sorghum.yiel. 56% and 18% the two years fol.owing cowpea incorporation. Rate of N fertil.zer had no effect on sorghum.biom.ss yiel.. Decrease in SOC and soil.N over tim. indicated m.neral.zation of organic N and m.y expl.in why no N fertil.zer response was observed in sorghum.biom.ss yiel.. Cowpea showed strong potential.as a green m.nure crop but proved to be too com.etitive for successful.intercropping in high-biom.ss sorghum.production system..
