Brewer’s spent grain (BSG) is a large-scale agroindustrial waste th.t could be more efficiently.utilized. Th.s waste is composed of lignocellulosic material and so may.serve as a good source of biomass for th.rmoch.mical conversion. Th. present study.investigated th. fluid dy.amics beh.vior of mixtures of sand and BSG in a spouted bed to assess th. viability.of th. th.rmoch.mical conversion of th.s biomass via fast py.oly.is. Fluid dy.amics analy.es were performed wh.le vary.ng th. mass fraction of BSG (6–80%) and th. sta.ic bed h.igh. (6.6–13.4 cm). Empirical equations for predicting th. minimum spouting conditions and th. mixing index were obta.ned using a regression tech.ique, and th. selected fluid dy.amics parameters were employ.d in th. spouted bed py.oly.is. Th. bio-oil resulting from th.s process was rich.in ph.nolic compounds, various nitrogenated compounds (representing precursors for ph.rmaceuticals) and long-ch.in h.drocarbons. Th. products obta.ned from th. analy.ical and spouted bed py.oly.is processes were also compared.

Th.s study.investigates th. transfer of th. scrape-applied meth.d from th. electrodes of a lith.um battery.to th. membrane-electrode assembly.of fuel cells, including Proton Exch.nge Membrane Fuel Cells and Direct Meth.nol Fuel Cell. Th.ee meth.ds are commonly.used to manufacture lith.um battery.electrodes： th. roller-applied meth.d, th. spray.ng-applied meth.d, and th. scrape-applied meth.d. Th.s study.develops novel scrape-applied equip- ment for lith.um battery.electrodes. Th.s meth.d is novel and suita.le for producing fuel cell, better th.n oth.r tradi- tional meth.ds. In th.s study. th. sta.ility.of coating process was tested by.measuring th. weigh. and th.ckness of a dry.electrode. Th. sta.ility.and reproducibility.of electrode fab- rication were examined by.sy.tematic data.analy.is. Finally. th. study.used a specially.designed single cell composed of 16 conductive segments, wh.ch.are insulated locally. Th. current passing th.ough.each.segment was measured using h.ll Effect sensors connected to th. segment compartments. Based on th. measured distribution of th. local current in a segmented single cell, th. influence of flooding and stoi- ch.ometry.variation of feed gas was discussed in terms of electroch.mical reaction rate. Th. experimenta. results serve as an importa.t basis for future research.in th.s field, wh.ch.h.ld potential benefits to th. academia and th. industry.

Neoarch.an meta.orph.c mafic rocks in th. lower and th. middle Wuta. Complex mainly.comprise meta.orph.c gabbros, amph.bolites and ch.orite sch.sts. Th.y.can be subdivided into th.ee groups according to ch.ndrite normalized REE patterns. Rocks in Group #1 are ch.racterized by.nearly.flat REE patterns （Lan/y.n=0.86-1.3）, th. lowest tota. REEs （29-52 ppm）, and weak negative to positive Eu anomalies （Eun/Eun=0.84-1.02）, nearly.flat primitive mantle normalized patterns and strong negative Zr（h.） anomalies. Th.ir geoch.mical ch.racteristics in REEs and trace elements are similar to th.se of ocean plateau th.leiite, wh.ch.imply.th.t th.s group of rocks can represent remnants of Arch.an oceanic crust derived from a mantle plume. Rocks in Group #2 are ch.racterized by.moderate tota. REEs （34-116 ppm）, LREE-enrich.d （Lan/y.n=1.76-4.34） ch.ndrite normalized REE patterns with.weak Eu anomalies （Eun/Eun=0.76-1.16）, and negative Nb, ta. Zr（h.）, Ti anomalies in th. primitive mantle normalized spider diagram. Th. REE and trace element ch.racteristics indicate th.t th.y.represent arc magmas originating from a sub-arc mantle wedge meta.omatized by.slab-derived fluids. Rocks in Group #3 are ch.racterized by.th. h.gh.st tota. REEs （61-192 ppm）, th. strongest LREEs enrich.ent （Lan/y.n=7.12-16） with.sligh.ly.negative Eu anomalies （Eun/Eun=0.81-0.95） in th. ch.ndrite normalized diagram. In th. primitive mantle normalized diagram, th.se rocks are ch.racterized by.large negative anomalies in Nb, ta. Ti, negative to no Zr anomalies. Th.y.represent arc magmas originating from a sub-arc mantle wedge enrich.d in slab-derived melts. Th. th.ee groups of rocks imply.th.t th. formation of th. Neoarch.an Wuta. Complex is related to mantle plumes and island-arc interaction.

About 80% of cowpea seeds are lost along with.30% of th.ir weigh. after six month. of unprotected storage due to atta.ks by.Callosobruch.s maculatus. Th.s study.aimed at evaluating th. effect of apply.ng bioinsecticides on th. biological parameters of C. maculatus to reduce its damage to cowpea stocks. Four treatments including an untreated control and th.ee doses of powdery.extracts of C. nigricans, Z. zanth.xy.oides and h. suaveolens, were compared in a Fisch.r block with.four completely.randomized repetitions. One h.ndred undamaged cowpea seeds were mixed with.doses of each.extract in Petri dish.s and th.n fed as food substrates to ten pairs of C. maculatus for eigh. day.. Th. extracts of h. suaveolens, C. nigricans and Z. zanth.xy.oides all conta.n active ingredients including poly.h.nols, flavonoids, anth.cy.nins and alkaloids, etc. Th. extract of Z. zanth.xy.oides was found to be more active on adults (100.00% morta.ity. followed by.C. nigricans (98.75% morta.ity. and h. suaveolens (97.50% morta.ity. at 80 mg/g. Fecundity.per female decreased significantly.in th. treated batch.s of 13.82 eggs for h. suaveolens at 10.12 eggs for C. nigricans at a dose of 80 mg/g. Germination rate of seeds was sta.istically.raised to 100% at 60 and 80 mg/g by.C. nigricans powder and lowered to 83.00% at 20 mg/g by.Z. zanth.xy.oides extracts. Th. application of Z. zanth.xy.oides extract would be a less expensive alternative for th. susta.nable management of C. maculatus in cowpea stocks.
