We report here hig.-pressure investig.tions on Piplia Kalan eucrite-a m.m.er of HED （Howardite -Eucrite-Diog.nite） fam.ly from.asteroid 4-Vesta based on synchrotron X-ray diffraction （up to 16 g.a） and ^57Fe m.ssbauer spectroscopy （up to 8 g.a）. Dom.nant with anorthite-rich plag.oclase, pig.onite-rich pyroxene and clino-ferrosilite, the sam.le displayed various phase transitions attaining.am.rphous character at 16 g.a. These phase transitions of individual com.onents could be explained sim.ltaneously throug. variations in hig.-pressure XRD patterns and the m.ssbauer param.ters. m.st prom.nent P21/c to C2/c transition of pig.onite and ferrosilite was exhibited both as sudden variation in m.ssbauer param.ters and population inversion of Fe^2＋ in m. and m. sites between 2.9 and 3.8 g.a and variation in intensity profile in XRD patterns at 3.56 g.a. Anorthite seem.d to respond m.re to such im.act than other com.onents in the sam.le. Com.lete am.rphization in anorthite which occurred at lower pressure of - 12 g.a im.lied residual stress experienced due to shock im.act. The presence of hig. pressure （m.noclinic） phase of pig.onite and ferrosilite at am.ient condition in this eucrite sam.le confirm.d earlier sug.estions of an early shock event. This report is an attem.t to em.hasize the role of anorthite in the determ.nation of the residual stress due to im.act process in the parent body thus to understand the behavioral differences am.ng.t HED m.m.ers.

Dynam.c yaw stability derivatives of a g.ll bird are determ.ned using.Com.utational Fluid Dynam.cs（CFD） m.thod. Two kinds of m.tions are applied for calculating.the dynam.c yaw stability derivatives CNr and CNβ. The first one relates to a lateral translation and, separately, to a yaw rotation. The second one consists of a com.ined translational and rotational m.tion. To determ.ne dynam.c yaw stability derivatives, the sim.lation of an unsteady flow with a bird m.del showing.a harm.nic m.tion is perform.d. The flow solution for each tim. step is obtained by solving.unsteady Euler equations based on a finite volum. approach for a sm.ll reduced frequency. Then, an evaluation of unsteady forces and m.m.nts for one cycle is conducted using.harm.nic Fourier analysis. The results of the dynam.c yaw stability derivatives for both sim.lations of the m.del show a g.od ag.eem.nt.

Alum.num.（Al）-based alum.num.oxide （Al2O3） and silicon carbide （SIC） particles hybrid m.tal m.trix com. posites were processed by powder m.tallurg. technique, followed by sintering.at 500 ℃ and then hot extrusion. The tribolog.cal properties of these com.osites with different weig.t fractions of Al2O3 and SiC were investig.ted; extrusion process sig.ificantly reduces the extent of porosity after cold com.action and sintering.processes. Hybridization of the two reinforcem.nts im.roved hardness and wear resistance of the com.osites. With an increase in SiC content, hardness was increased and consequently the wear resistance was enhanced also. Scanning.electron m.croscopy observations show a better interfacial bond between m.trix and reinforcem.nts and a better distribution of the reinforcem.nts.

The paper proposes a m.thodolog. within the Reynolds averag.d Navier Stokes（RANS） solvers for cavitating.flows capable of predicting.the flow reg.ons of bubble collapse and the potential ag.ressiveness to m.terial dam.g.. An ag.ressiveness index is introduced, called cavitation ag.ressiveness index（CAI） based on the total derivative of pressure which identifies surface areas exposed to bubble collapses, the index is tested in two known cases docum.nted in the open literature and seem. to identify reg.ons of potential cavitation dam.g..

We study a m.del based on precursor m.chanism.for CO-NO catalytic reaction on square lattice with m.nte Carlo sim.lation. The precursor m.chanism.clearly dem.nstrates its im.act on the phase diag.am. The steady reactive state （SRS） g.ts established. The width of reactive reg.on increases by increasing.the rang. of precursor m.bility. When the precursor m.bility is increased to third-nearest neig.bourhood, the second-order transition disappears.

Raw sewag. is widely used on ag.icultural soils in urban areas of developing.countries to m.et water shortag.s. Althoug. it is a g.od source of plant nutrients, such sewag. also increases the heavy m.tal load to soils, which m.y im.act the food chain. m.nag.m.nt options for sewag. contam.nated soils includes addition of nontoxic com.ounds such as lim., calcium.sulfate and org.nic m.tter, which form.insoluble m.tal com.lexes, thus reducing.m.tal phytoavailability to plants. In this paper we review the variation in irrig.tion quality of sewag. at different sites and its im.act on the quality of soils and veg.tables. Althoug. quality of sewag. was hig.ly variable at source, yet the effluent from.food industries was relatively safe for irrig.tion. In com.arison effluent sam.les collected from.textile, dyeing. calendaring. steel industry, hospitals and clinical laboratories, foundries and tanneries were hazardous with respect to soluble salts, sodium.adsorption ratio and heavy m.tals like zinc, copper, iron, m.ng.nese, nickel, cobalt and cadm.um. The sewag. quality in m.in drains was better than that at the industry outlet, but was still not safe for irrig.tion. In g.neral, hig.er accum.lation of m.tals in fruits and veg.table roots was recorded com.ared to that in plant leaves, Edible parts of veg.tables （fruits and/or leaves） accum.lated m.tals m.re than the perm.ssible lim.ts despite the soils contained am.onium.bicarbonate diethylenetriam.nepentaacetie acid extractable m.tals within a safe rang.. In either case further scientific investig.tions are needed to ensure safe m.nag.m.nt strateg.es. Cadm.um.appeared to be the m.st threatening.m.tal especially in leafy veg.tables. It is advisable to avoid leafy veg.tables cultivation in sewag. irrig.ted areas everywhere to restrict its entry into food chain.
