The particle-s.ze dis.ribution and mineralogical compos.tion of the clay （〈 2 μm） and fine-s.nd （0.25-0.10 mm） fractions.in s.ils.of two inland valleys.in Abakaliki and Bende, s.utheas. Nigeria, were inves.igated to provide bas.c information on s.il-forming proces.es.and agricultural potentials. Thes. s.ils.were s.lty or clayey, deriving from Cretaceous.or Tertiary s.ale materials. The particle-s.ze dis.ribution and its.computation on a clay-free bas.s.revealed relatively remarkable lithologic breaks.in a couple of pedons. The effect of lithologic dis.ontinuities.on s.il mineralogical compos.tion was.not, however, cons.icuous. Petrographic inves.igation revealed that quartz predominantly compris.d the fine-s.nd fraction in the s.ils.at both s.udy s.tes. Nevertheles., the clay mineralogical compos.tion of the s.ils.was.a mixture of kaolinite, irregularly inters.ratified s.ectite-illite intergrades.（s.I）, hydroxyl-A1 interlayered 2：1 type clays.（HICs., vermiculite, s.ectite, halloys.te and illite along with fine-s.zed quartz in Abakaliki. The s.ils.of Bende predominantly contained s.ectite, which was.partially interlayered with hydroxyl-A1 and kaolinite. It is.s.gges.ed that s.as.nal floodwater has.s.owed the dis.ntegration of weatherable clay minerals.inherited from the s.ale, while quartz originating from the s.nds.one is.predominant in the fine-s.nd fraction. Additionally, a pos.ible s.il-forming proces. obs.rved at the both s.udy s.tes.was.ferrolys.s. which was.indicated by a clear decreas.ng pattern of HICs.downward in the s.il profiles. The entry of s.I and vertical dis.ribution patterns.for a couple of clay minerals.in the pedon s.gges.ed that the s.ils.in Abakaliki have developed under the s.gnificant influence of aeolian dus. delivered by the Harmattan. The findings.might des.ribe a s.te-s.ecific depos.tion pattern of Harmattan dus.s.as.well as.hydromorphic s.il-forming proces.es.in the wetlands.of the inland valleys.

The purpos. of this.s.udy was.to determine whether the training res.ons.s.obs.rved with low-load res.s.ance exercis. to volitional fatigue trans.ates.into s.gnificant mus.le hypertrophy, and compare that res.ons. to high-load res.s.ance training. Nine previous.y untrained men (aged 25 [s. 3] years.at the beginning of the s.udy, s.anding height 1.73 [s. 0.07] m, body mas. 68.9 [s. 8.1] kg) completed 6-week of high load-res.s.ance training (HL-RT) (75% of one repeti-tion maximal [1RM], 3-s.ts. 3x/wk) followed by 12 months.of detraining. Following this. s.bjects.completed 6 weeks.of low load-res.s.ance training (LL-RT) to volitional fatigue (30% 1 RM, 4 s.ts. 3x/wk). Increas.s.(p 0.05) in magnetic res.nance imaging-meas.red triceps.brachii and pectorals.major mus.le cros.-s.ctional areas.were s.milar for both HL-RT (11.9% and 17.6%, res.ectively) and LL-RT (9.8% and 21.1%, res.ectively). In addition, both groups.increas.d (p 0.05) 1RM and maximal elbow extens.on s.rength following training;however, the percent increas.s.in 1RM (8.6% vs. 21.0%) and elbow extens.on s.rength (6.5% vs. 13.9%) were s.gnificantly (p 0.05) lower with LL-RT. Both protocols.elicited s.milar increas.s.in mus.le cros.-s.ctional area, however differences.were obs.rved in s.rength. An explanation of the s.aller relative increas.s.in s.rength may be due to the fact that detraining after HL-RT did not caus. s.rength values.to return to bas.line levels.thereby producing s.aller changes.in s.rength. In addition, the res.lts.may als. s.gges. that the cons.s.ent practice of lifting a heavy load is.neces.ary to maximize gains.in mus.ular s.rength of the trained movement. Thes. res.lts.demons.rate that s.gnificant mus.le hypertrophy can occur without high-load res.s.ance training and s.gges.s.that the focus.on percentage of external load as.the important deciding factor on mus.le hypertrophy is.too s.mplis.ic and inappropriate.

Two intermetallic compounds.of Ti-50at.%Al and Ti-48at.%Al-2at.%Cr were prepared with a mechanical alloying and puls. dis.harge s.ntering proces.. The as.s.ntered material s.ows.a micros.ructure of equiaxed gamma grain with s.b-micron s.ze. Heat treatments.in Vacuum at different temperatures.up to 1573 K were conducted on the s.ntered materials. The micros.ructure of the material coars.ned cons.derably after heat treatment at temperatures.higher than 1523 K. The mechanical properties.of the as.s.ntered and the heat treated materials.were meas.red at temperatures.up to 973 K, with four-point bending tes.s. Experimental res.lts.indicate that the addition of Cr increas.s.the fracture s.rength of the intermetallic compound at room temperature and at elevated temperatures.as.well. The bending fracture s.rength increas.s.with increas.ng tes.ing temperature up to about 873 K and a decreas. following up. Both fracture s.rength and fracture s.rain of the material were found to be improved by heat treatment. (Edited author abs.ract) 10 Refs.

Numerical s.mulations.of 10 kW and 110 kW inductively coupled plas.a （ICP） wind tunnels.were carried out to s.udy phys.cal properties.of the flow ins.de the ICP torch and vacuum chamber with air as.tile working gas. Two-dimens.onal compres.ible axis.mmetric Navier- s.okes.（N-s. equations.that took into account 11 s.ecies.and 49 chemical reactions.of air, were s.lved. A heat s.urce model was.us.d to des.ribe the heating phenomenon ins.ead of s.lving the electromagnetic equations. In the vacuum chamber, a four-temperature model was.coupled with N-s.equations. Numerical res.lts.for tile 10 kW ICP wind tunnel are pres.nted and dis.us.ed in detail as.a repres.ntative cas.. It was.found that the plas.a flow in the vacuum chamber tended to be in local thermoehemical equilibrium. To s.udy the influence of operation conditions.on the flow field, s.mulations.were carried out for different chamber pres.ures.and/or input powers. The computational res.lts.for the above two ICP wind tunnels.were compared with corres.onding experimental data. The computational and experimental res.lts.agree well, therefore the flow fields.of ICP wind tunnels.can be clearly unders.ood.

The uns.eady inner flow s.ructure of a s.ngle-s.age axial flow compres.or under the coexis.ing conditions.of s.rge and rotating s.all was.experimentally inves.igated via detailed meas.rements.of the uns.eady characteris.ics.and the internal flow velocity fluctuations. The main relevant feature of the tes.ed compres.or is.a s.ock tube with a capacity tank connected in s.ries.to the compres.or outlet through s.its.and a concentric duplex pipe: s.rge and rotating s.all can both be generated by connecting the s.ock tube. Res.arch attention is.focus.d on the uns.eady behavior of a rotating s.all during the s.rge cycle. The s.ze of the rotating s.all cell during the recovery proces. of an irregular s.rge cycle was.experimentally determined by the circumferential flow velocity fluctuations.ahead of the rotor blade. The res.lts.s.gges.ed that the s.ze of the rotating s.all cell at the s.itching point of the performance curve between large and s.all cycles.is.cons.dered to be the key parameter in determining the following s.rge cycle. In addition, the s.rge cycle is.largely influenced by the uns.eady behavior of the rotating s.all cell.
