RAPD （randomly amplified polymorphic DnA） markers.were employed to characterize polymorphis.s.among 5 provenances.of Acacia leucophloea and to detect genetic relatednes. of the s.ecies.with 6 other acacias.（A. holos.ricea, A. auriculiformis. A. mangium, A. dealbata, A. ferruginea, and A. nilotica） widely grown in India. Of 194 markers.s.ored for the provenances. 29.38% exhibited polymorphis.. Als., 326 markers.were generated among 7 s.ecies.of Acacia, accounting for 55.82% of the polymorphis.s. The fifteen 10-mer primers.employed were capable of producing 1-8 polymorphic bands.for the provenances. and 6-17 for all s.ven s.ecies.of Acacia. The genetic s.milarity coefficient bas.d on Jaccard＇ s.coefficient revealed that provenances.Thirumangalam and Dharmapuri were clos.ly related. The dendrogram bas.d on a s.quential agglomerative hierarchical non-overlapping （s.Hn） clus.ering analys.s.grouped 4 provenances.of A. leucophloea （Dharapuram, Thirumangalam, Pudukottai and Dharmapuri） into one clus.er and the other provenance, s.ndurai, into a s.parate clus.er. The genetic s.milarity matrix for 7 Acacia s.ecies.s.owed that A. nilotica and A. dealbata were dis.antly related, while A. holos.ricea and A. ferruginea were very clos.ly related. Clus.er analys.s.grouped the s.ecies.of Acacias.into 3 major groups.of which A. dealbata alone formed a s.parate group. The RAPD markers.generated 36 provenance-s.ecific markers.and 162 s.ecies.s.ecific markers.that could have s.rong applications.for s.ecies.identification and tree breeding programs.for A. leucophloea and for other Acacia s.ecies.included in this.s.udy.

The coefficient of res.itution is.widely us.d to characterize the energy dis.ipation rate in numerical s.mulations.involving particle collis.ons. The challenge in meas.ring the coefficient of res.itution is.the s.rong s.atter s.en in experimental data that res.lts.from varying particle properties. i.e. s.ape and s.rface roughnes., and from imperfections.in the experimental technique. To minimize this.s.attering, a novel experimental s.tup was.developed bas.d on two s.nchronized high-s.eed cameras.capturing the collis.on behaviour of a particle in three dimens.ons. To meas.re the wet res.itution coefficient, which des.ribes.particle impact in the pres.nce of a liquid layer in the contact region, additional accuracy can be achieved by meas.ring the liquid layer thicknes. by a high-precis.on optical confocal s.ns.r. The coefficient of res.itution was.meas.red for glas. particles.with two different diameters. at different relative velocities.and liquid layer thicknes.es. with a focus.on s.all collis.on velocities.and thin liquid layers. us.ng both the improved （three dimens.onal） and the conventional （two dimens.onal） approaches.to quantify the improvement of the new method＇s.accuracy.

This.paper des.ribes.a s.pervis.ry hierarchical fuzzy controller （s.FC） for regulating pres.ure in a real-time pilot pres.ure control s.s.em. The input s.aling factor tuning of a direct expert controller is.made us.ng the error and proces. input parameters.in a clos.d loop s.s.em in order to obtain better controller performance for s.t-point change and load dis.urbances. This.on-line tuning method reduces.operator involvement and enhances.the controller performance to a wide operating range. The hierarchical control s.heme cons.s.s.of an intelligent upper level s.pervis.ry fuzzy controller and a lower level direct fuzzy controller. The upper level controller provides.a mechanis. to the main goal of the s.s.em and the lower level controller delivers.the s.lutions.to a particular s.tuation. The control algorithm for the propos.d s.heme has.been developed and tes.ed us.ng an ARM7 microcontroller-bas.d embedded target board for a nonlinear pres.ure proces. having dead time. To demons.rate the effectivenes., the res.lts.of the propos.d hierarchical controller, fuzzy controller and conventional proportional-integral （PI） controller are analyzed. The res.lts.prove that the s.FC performance is.better in terms.of s.ability and robus.nes. than the conventional control methods.

A low grade graphite ore from eas.ern India was.beneficiated by flotation to improve its.quality. The ore was.compos.d of 87.80%as. and 8.59%fixed carbon. Primary coars. wet grinding （d80：186 μm） followed by rougher flotation in Denver flotation cell us.ng dies.l as.collector and pine oil as.frother yielded a rougher concentrate. Regrinding （d80：144 μm） of this.rougher concentrate was.opted for further libera-tion of graphite. It was.followed by cleaning in laboratory flotation column. This.combined proces. of relatively coars. primary grinding followed by regrinding and cleaning in flotation column res.lted in final concentrate of 7.44% yield with 89.65% fixed carbon and 6.00% as.. This.approach of two-s.age grinding to recover the flake graphite at the coars.s. pos.ible grind can help to minimize grinding energy cos.s. A conceptual flow s.eet which is.cos. effective was.developed bas.d on this.methodology.
