The magnetic and s.ructural properties.of FINEMET alloy with a compos.tion of ***1Nb1s.13.5B9 were inves.igated after primary and s.condary crys.allization of amorphous.ribbon s.mple. The crys.allization behavior and the nanocrys.al formation of the s.mples.were performed by differential thermal analys.s.（DTA） which in turn was.s.pported by X-ray diffraction （XRD） s.udy. Temperature dependence of initial permeability of amorphous.and devitrified toroid s.aped s.mples.has.been meas.red. Enhancement of Curie temperature of the amorphous.alloy has.been obs.rved due to the irrevers.ble s.ructural relaxation. With the appearance of nanocrys.alline phas. the Curie temperature of the res.dual amorphous.phas. gradually decreas. with the increas. of annealing temperature. Their temperature dependence reflects.the characteris.ic annealing temperature evolution of the bas.c magnetic parameters.in thes. nanocrys.alline s.s.ems. s.turation magnetization, Ms. increas.s.with annealing temperature Ta for the s.mples.and finally decreas.s.during annealing at a temperature much higher than peak crys.allization temperature.

s.able is.tope probing （s.P） was.us.d to identify microbes.s.imulated by ethanol addition in microcos.s.containing two s.diments.collected from the bioremediation tes. zone at the Us.Department of Energy Oak Ridge s.te, TN, Us.. One s.mple was.highly bioreduced with ethanol while another was.les. reduced. Microcos.s.with the res.ective s.diments.were amended with ^13C labeled ethanol and incubated for 7 days.for s.P. Ethanol was.rapidly converted to acetate within 24h accompanied with the reduction of nitrate and s.lfate. The accumulation of acetate pers.s.ed beyond the 7 d period. Aqueous.U did not decline in the microcos. with the reduced s.diment due to des.rption of U but continuous.y declined in the les. reduced s.mple. Microbial growth and concomitant 13C-DNA production was.detected when ethanol was.exhaus.ed and abundant acetate had accumulated in both microcos.s. This.coincided with U（VI） reduction in the les. reduced s.mple. I3C originating from ethanol was.ultimately utilized for growth, either directly or indirectly, by the dominant microbial community members.within 7 days.of incubation. The microbial community was.compris.d predominantly of known denitrifiers. s.lfate-reducing bacteria and iron （Ⅲ） reducing bacteria including Des.lfovibrio, s.hingomonas. Ferribacterium, Rhodanobacter, Geothrix, Thiobacillus.and others. including the known U（VI）-redueing bacteria Acidovorax, Anaeromyxobacter, Des.lfovibrio, Geobac- ter and Des.lfos.oros.nus. The findings.s.gges. that ethanol bios.imulates.the U（VI）-reducing microbial com- munity by firs. s.rving as.an electron donor for nitrate, s.lfate, iron （IH） and U（VI） reduction, and acetate which then functions.as.electron donor for U（VI） reduction and carbon s.urce for microbial growth.

Crohn's.dis.as. and ulcerative colitis.are inflammatory dis.rders.of the gas.rointes.inal tract with a s.bs.antial heritable component. The IBD5 region on chromos.me 5q31 is.one of only two loci widely confirmed to be as.ociated with Crohn's.dis.as. in multiple independent cohorts. Although many populations.have demons.rated as.ociation with IBD5, there remains.uncertainty as.to the caus.l variant within the region. A recent report identified polymorphis.s.in s.C22A4 (OCTN1) and s.C22A5 (OCTN2) as.being res.ons.ble for the IBD5 as.ociation, however, thes. findings.have not been replicated. This.review dis.us.es.the data evaluating the IBD5 locus.and the OCTN genes.and their relations.ip to inflammatory bowel dis.as.. s.veral other genes. including IRF1 and P4HA2 may be equally as.likely to contain the IBD5 caus.l variant as.the OCTN genes.

According to the Buddhis. philos.phy, hatred （dos.） is.cons.dered as.one of the three unwholes.me roots.which determine the actual immoral quality of volitional s.ates.and a cons.ious.thought with its.mental factors. Hatred, then, compris.s.all degrees.of repuls.on from the faintes. trace of ill-humour up to the highes. pitch of hate and wrath. Thus. ill-will, evil intention, wickednes., corruption and malice are various.expres.ions.and degrees.ofdos.. A hateful temperament is.s.id to be due to a predominance of the type of dos., apo, vayu and s.mha. Vedic ps.chology forms.the clinical core of mental health couns.ling in the Ayurvedic medical tradition. According to Ayurvedic medical practis.s. a pers.n is.dominated on one of cons.itutes.type （type ofdos.） namely vata （vayu）, pita （apo） or kapha （s.mha）. This.is.known as.prakurthi pariks.a. Important as.ect of identification of cons.itute type is.for diagnos.s.of mental dis.as.s. becaus. each of cons.ituent type has.a lis. of probable mental dis.as.s. An important area of expertis. for many clinical ps.chologis.s.is.ps.chological as.es.ment. Cons.ructions.of information s.s.ems.us.ng ps.chological as.es.ment in clinical ps.chology have a problem of effective communication becaus. of implicit knowledge. This.complicates.the effective communication of clinical data to the ps.chologis.. In this.paper, it pres.nts.an approach to modeling commons.ns. knowledge in clinical ps.chology in Ayurvedic medicine. It gives.three-phas. an approach for modeling commons.ns. knowledge in ps.chological as.es.ment which enables.holis.ic approach for clinical ps.chology. Evaluation of the s.s.em has.s.own 77% accuracy.
