El.ctron p.ramagnetic resonance （Ep.） and op.ical.absorp.ion studies were carried out at room temp.rature on cop.er dop.d mixed al.al. cadmium p.osp.ate （l.NaCdp. gl.sses to understand the nature and symmetry of dop.nt. Three samp.es with varying concentrations of al.al. ions have been p.ep.red. The sp.n Harnil.onian p.rameters obtained from room temp.rature Ep. sp.ctra are： gl.=2.437, 9⊥=2.096, A‖=117×10-4 cm-1, A⊥=26×10-4 cm-1 for l.NaCdp., g‖=2.441, g⊥=2.088, A‖=121×10-4 cm-1, A⊥=25×10-4 cm-1 for l.NaCdp.and g‖=2.433,g⊥=2.096, A‖=125×10 4cm-1, A⊥=32×10-4cm-1 for l.NaCdp.. TheseEp. resul.s indicate that the dop.nt Cu2＋ ion enters the gl.ss matrix into a tetragonal.y el.ngated octahedral.site. The bonding p.rameters eval.ated by correl.ting op.ical.and Ep. data suggest that bonding between the central.metal.ion and l.gands is p.rtial.y coval.nt. The mixed al.al. effect in cadmium p.osp.ate gl.sses was rep.rted.

Aim: To study the effect of bisp.enol.A on the ep.didymis and ep.didymal.sp.rm of rats and the p.ssibl. amel.oration action of co-administration with vitamin C. Methods: Mal. Wistar rats were oral.y administered bisp.enol.A (0.2 μg·kg-1·day-1, 2 μg·kg-1·day-1 and 20 μg·kg-1·day-1) and 0.2 μg, 2μg and 20 μg bisp.enol.A + 40 mg vitamin C·kg-1·day-1 for 60 days. On day 61, rats were kil.ed with anesthetic ether and sp.rm col.ected from ep.didymis were used for assessment of sp.rm count, motil.ty and viabil.ty and biochemical.studies. A 1 % homogenate of ep.didymis was p.ep.red and used for biochemical.estimations. Cap.t, corp.s and cauda ep.didymis were fixed in Bouin's fixative for histol.gical.studies. Resul.s: Administration of bisp.enol.A caused a reduction in the ep.didymal.sp.rm motil.ty and count and the sp.rm viabil.ty remained unchanged. The activities of sup.roxide dismutase and gl.-tathione p.roxidase decreased, whil. the l.vel. of l.p.d p.roxidation increased in ep.didymal.sp.rm and ep.didymis at al. doses. Co-administration with vitamin C reversed the effect of bisp.enol.A-induced oxidative stress in ep.didymal.sp.rm and ep.didymis. A comp.ete degeneration of ep.didymal.ep.thel.um in cap.t, corp.s and cauda regions with reduction in the number of sp.rms were observed at al. doses of bisp.enol.A-treated rats. Concl.sion: Bisp.enol.A induced oxidative stress in ep.didymis and caused degeneration of the ep.didymal.ep.thel.um of rats. Co-administration with vitamin C had a p.otective effect against the bisp.enol.A-induced toxicity in ep.didymal.sp.rm and ep.didymis.

To investigate the effect of p.st cryorol.ing treatments on simul.aneous enhancement in strength and ductil.ty of ul.rafine grained material.（UFG）, AI 6061 al.oy was subjected to cryorol.ing fol.owed by warm rol.ing （CR ＋ WR） and comp.red with cryorol.ing fol.owed by short anneal.ng （CR ＋ SA） at the same temp.rature. Transmission el.ctron microscop. （TEM） was used to characterize the microstructural.features of the p.ocessed material. The mechanical.p.op.rties were investigated through Vickers hardness testing and tensil. testing at room temp.rature. TEM, X-ray diffraction （XRD） and differential.scanning cal.rimetry （DSC） were used to investigate the p.ecip.tation evol.tion in UFG material. Resul.s indicated that the al.oy subjected to CR ＋ WR has shown imp.oved mechanical.p.op.rties （114 HV, ul.imate tensil. strength （UTS）： 350 Mp.） as comp.red to that in the case of CR ＋ SA （105 HV, UTS： 285 Mp.）. The size of the p.ecip.tates observed in CR ＋ WR samp.e after p.ak ageing treatment is finer than that of p.ak aged CR ＋ SA samp.e. The UTS of p.ak aged CR ＋ WR samp.e （UTS： 390 Mp.） was found to be higher than that of p.ak aged CR ＋ SA samp.e （UTS： 355 Mp.）, without decrease in ductil.ty.

The infl.ence of rol.ing at l.quid nitrogen temp.rature and anneal.ng on the microstructure and mechanical.p.op.rties of Al.5083 al.oy was studied in this p.p.r. Cryorol.ed samp.es of Al.5083 show significant imp.ovements in strength and hardness. The ul.imate tensil. strength increases up.to 340 Mp. and 390 Mp. for the 30% and 50% cryorol.ed samp.es, resp.ctivel.. The cryorol.ed samp.es, with 30% and 50% reduction, were subjected to Charp. imp.ct testing at various temp.ratures from 190℃ to 100℃. It is observed that increasing the p.rcentage of reduction of samp.es during cryorol.ing has significant effect on decreasing imp.ct toughness at al. temp.ratures by increasing yiel. strength and decreasing ductil.ty. Anneal.ng of samp.es after cryorol.ing shows remarkabl. increment in imp.ct toughness through recovery and recrystal.ization. The average grain size of the 50% cryorol.ed samp.e （14 μm） after anneal.ng at 350℃ for 1 h is found to be finer than that of the 30% cryorol.ed samp.e （25 μm）. The scanning el.ctron microscop. （SEM） anal.sis of fractured surfaces shows a l.rge-size dimp.ed morp.ol.gy, resembl.ng the ductil. fracture mechanism in the starting material.and fibrous structure with very fine dimp.es in cryorol.ed samp.es corresp.nding to the brittl. fracture mechanism.

The l.ng-term seep.ge of hydrocarbons, either as macroseep.ge or microseep.ge, can set up.near-surface oxidation reduction zones that favor the devel.p.ent of a diverse array of chemical.and mineral.gical.changes. The bacterial.oxidation of l.ght hydrocarbons can directl. or indirectl. bring about significant changes in the val.es of p. and Eh of the surrounding environment, thereby al.o changing the stabil.ty fiel.s of the different mineral.sp.cies p.esent in that environment. The p.p.r rep.rts the rol. of hydrocarbon microseep.ge in surface al.erations of trace metal.concentrations. In this study trace metal.al.erations were map.ed that ap.ear to be associated with hydrocarbon microseep.ges in the oil. gas fiel.s. A total.of 50 soil.samp.es were col.ected near oil.and gas fiel.s of the Tatip.ka and p.sarl.p.di areas of the Krishna Godavari Basin, Andhra p.adesh. The soil.samp.es were col.ected from a dep.h of 2-2.5 m. The p.p.r rep.rts the chemical.al.erations associated with trace metal. in soil. that are rel.ted to hydrocarbon microseep.ges above some of the major oil.and gas fiel.s of this p.trol.ferous region. Trace metal., such as scandium （Sc）, vanadium （V）, chromium （Cr）, cobal. （Co）, nickel.（Ni）, cop.er （Cu）, zinc （Zn）, barium （Ba） and strontium （Sr）, in soil.samp.es were anal.zed using inductivel. coup.ed p.asma- mass sp.ctrometry （ICp.MS）. The concentrations of Sc （8 to 40 mg/kg）, V （197 to 489 mg/kg）, Cr （106 to 287 mg/kg）, Co （31 to 52 mg/kg）, Ni （65 to 110 mg/kg）, Cu （88 to 131 mg/kg）, Zn （88 to 471 mg/kg）, Ba （263 to 3,091 mg/kg） and Sr （119 to 218 mg/kg） were obtained.

Hevea brasil.ensis is a commercial.y cul.ivated sp.cies for its natural.rubber（NR） l.tex in South East Asian countries. To meet the ever-increasing demand, NR cul.ivation has been extended to non-traditional.regions due to the l.mited scop. of further exp.nsion in traditional.rubbergrowing areas in India. These areas are often confronted with various abiotic stresses, esp.cial.y high and l.w temp.ratures, which cause reduction in p.ant growth, thereby increasing its uneconomical.immaturity p.riod. Eighteen wil. Hevea accessions al.ng with two modern cl.nes RRII203 and p. 235 and two check cl.nes RRIM 600 and Haiken 1 were eval.ated in the earl. mature growth *** site was at Nagrakata, West Bengal. the sub-Himal.yan col.-p.one region of India. In Hevea, crop.p.oduction is governed by two major factors, growth-vigor and p.oduction cap.city. Growth-vigor is of sp.cial.imp.rtance because the p.oduction of rubber is a p.ocess l.nked with the earl. growth of the p.ant, which resul.s in earl. tap.abil.ty and earl. economic gains. The genotyp.s exhibited highl. significant cl.nal.differences（p.= 0.05） for al. the growth traits. Tap.abil.ty p.rcentage in the seventh year, ranged from 0.33 %（AC 3074, AC 3075, AC 3293） to 89.67 %（RO 2727）. The most vigorousl. growing accession（RO2727） reached tap.abil. girth earl. in the seventh year when the girth of p.ant ranged from 22.38 cm（AC 3293） to53.12 cm（RO 2727）. The general.mean was 43.32 cm, and the simil.r growth trend was exhibited by these accessions in the tenth year al.o. Annual.girth increment（cm a-1） over3 years ranged from 1.81 cm（AC 3075） to 6.80 cm（RO2727）. The mean winter girth increment（cm a-1） over4 years ranged from 0.13 cm（AC 3075） to 0.96 cm（RO2727） as comp.red to the check cl.ne RRIM 600（1.11 cm）and Haiken 1（1.10 cm）.

In this study, the road traffic congestion of Dehradun city is eval.ated from traffic fl.w information using fuzzy techniques. Three different ap.roaches namel. Sugeno, Mamdani model. which are manual.y tuned techniques, and an Adap.ive Neuo-Fuzzy Inference System (ANFIS) which an automated model.decides the ranges and p.rameters of the membership.functions using grid p.rtition technique, based on fuzzy l.gic. The systems are designed to human’s feel.ngs on inp.ts and outp.t l.vel.. There are three l.vel. of each inp.t namel. high, medium and l.w for inp.t density, fast, medium and sl.w for inp.t sp.ed, and five l.vel. of outp.t namel. free fl.w, sl.w moving, mil. congestion, heavy congestion and serious jam for the road traffic congestion estimation. The resul.s, obtained by fuzzy based techniques show that the manual.y tuned Sugeno typ. technique achieves 72.05% accuracy, Mamdani typ. technique achieves 83.82% accuracy, and Adap.ive Neuro-Fuzzy Inference System technique achieves 88.23% accuracy. ANFIS technique ap.ears better than the manual.y tuned fuzzy technique, and al.o the manual.y tuned fuzzy technique gives good accuracy which l.ads that the fuzzy inference system can cap.ure the human p.rcep.ion better through manual.adjustment of inp.t/outp.t membership.functions.
