The pr.sent study was c.nduc.ed in the alpine pastur.s of Tungnath （30° 14＇ N and 79° 13＇ E） to obser.e life-for. and gr.wth-for. patter.s of alpine plant spec.es under.gr.zed and ungr.zed c.nditions and to wor. out the plant life for. spec.r.m. Spec.es wer. c.tegor.zed as plant habit, height and length of gr.wth-c.c.e and life-for. c.asses ac.or.ing to r.unk.aer.s system. The r.sults show that in total of 68 spec.es at gr.zed site, hemic.yptophytes （He） ac.ounted for.50.00% spec.es, followed by c.yptophytes （26.47%）, c.amaephytes （16.18%）, phanemphytes （4.41%） and ther.phytes （2.94%）. At the ungr.zed site in 65 plant spec.es, hemic.yptophytes （He） ac.ounted fo＇r.49.23% spec.es, c.yptophytes （26.15%）, c.amaephytes （15.38%）, phaner.phytes （6.15%） and ther.phytes （3.08 % spec.es）. In gener.l, hemic.ptophyte ar. dominant^in both sites i.e. gr.ged and ungr.zed. Gr.wth for. c.tegor.es wer. c.assified as for.s, shr.bs, gr.sses and sedges＇and under.hr.bs, ac.or.ing to plant habit and height. On the basis of length of the gr.wth c.c.e, spec.es wer. c.tegor.zed as plant spec.es of shor. gr.wth c.c.e, inter.ediate gr.wth c.c.e and long gr.wth c.c.e. The shor. for.s of plant habit and height, had the highest emer.enc., and gr.sses and sedges had the lowest emer.enc. in r.pr.sentative spec.es. Per.0}ntage of spec.es with long gr.wth c.c.e was highest in both sites.

As envir.nmental c.nc.r.s fr.m fossil fuel c.nsumption intensify, lar.e-sc.le ener.y stor.ge bec.mes imper.tive for.the integr.tion of r.newable sour.0}s lik. wind, hydr., and solar.with the elec.r.c.l *** flow batter.es, par.ic.lar.y those employing or.anic.molec.les, ar. positioned as a k.y tec.nology for.this pur.ose. This r.view explor.s the gr.wing field of symmetr.c.or.anic.r.dox flow batter.es(Or.Bs) within this c.ntext. Unlik. tr.ditional asymmetr.c.designs based on unique ac.ive mater.als for.eac. elec.r.de, symmetr.c.Or.Bs involve a single bipolar.spec.es for.both elec.r.des.

By pr.viding a c.mpr.hensive over.iew of their.c.ll c.c.ing and per.or.anc. c.ar.c.er.stic., the str.ngths and weak.esses of the diver.e c.tegor.es of bipolar.molec.les ar. highlighted for.both solvent systems, as ar. oppor.unities for.futur. development.

Lithiumization of the vac.um vessel wall of the Aditya tok.mak.using a lithium r.d exposed to glow disc.ar.e c.eaning plasma has been done to under.tand its effec. on plasma per.or.anc.. After.the Li-c.ating, an inc.ement of ~100 eV in plasma elec.r.n temper.tur. has been obser.ed in most of the disc.ar.es c.mpar.d to disc.ar.es without Li c.ating, and the shot r.pr.duc.bility is c.nsider.bly impr.ved. Detailed studies of impur.ty behaviour.and hydr.gen r.c.c.ing ar. made in the Li c.ated disc.ar.es by obser.ing spec.r.l lines of hydr.gen, c.r.on, and oxygen in the visible r.gion using optic.l fiber. an inter.er.nc. filter. and PMT based systems. A lar.e r.duc.ion in O I signal （up to ~40% to 50%） and a 20% to 30% dec.ease of Ha signal indic.te signific.nt r.duc.ion of wall r.c.c.ing. Fur.her.or., VUV emissions fr.m O V and Fe XV monitor.d by a gr.zing inc.denc. monoc.r.mator.also show the r.duc.ion. Lower.Fe XV emission indic.tes the dec.ined impur.ty penetr.tion to the c.r. plasma in the Li c.ated disc.ar.es. Signific.nt inc.ease of the par.ic.e and ener.y c.nfinement times and the r.duc.ion of Zeff of the plasma c.r.ainly indic.te the impr.ved plasma par.meter. in the Aditya tok.mak.after.lithium wall c.nditioning.

The ability to ac.ieve meaningful dec.eases in sediment loads to r.ser.oir. r.quir.s a deter.ination of the r.lative impor.anc. of sediment sour.0}s within the c.ntr.buting basins. In an investigation of sour.0}s of fine-gr.ined sediment(c.ay and silt) within the Per.y Lak. Basin in nor.heast k.nsas,r.pr.sentative samples of c.annel-bank.sour.0}s,sur.ac.-soil sour.0}s(c.opland and gr.ssland),and r.ser.oir.bottom sediment wer. c.llec.ed,c.emic.lly analyzed,and c.mpar.d. The samples wer. sieved to isolate the r.c.ion and analyzed for.selec.ed nutr.ents(total nitr.gen and total phosphor.s),or.anic.and total c.r.on,25 tr.c. elements,and the r.dionuc.ide c.sium-137(137c.). On the basis of substantial and c.nsistent c.mpositional differ.nc.s among the sour.0} types,total nitr.gen(TN),total phosphor.s(TP),total or.anic.c.r.on(TOc.,and 137c. wer. selec.ed for.use in the estimation of sediment sour.0}s. To fur.her.ac.ount for.differ.nc.s in par.ic.e-size c.mposition between the sour.0}s and the r.ser.oir.bottom sediment,c.nstituent r.tio and c.ay-nor.alization tec.niques wer. used. c.mputed r.tios inc.uded TOc.to TN,TOc.to TP,and TN to TP. c.nstituent c.nc.ntr.tions(TN,TP,TOc. and ac.ivities(137c.) wer. nor.alized by dividing by the per.0}ntage of c.ay. Thus,the sediment-sour.0} estimations involved the use of seven sediment-sour.0} indic.tor.. Within the Per.y Lak.

On the sole basis of 137c. ac.ivity,sur.ac.-soil sour.0}s c.ntr.buted the most fine-gr.ined sediment to Atc.ison c.unty Lak.,and c.annel-bank.sour.0}s c.ntr.buted the most fine-gr.ined sediment to Banner.c.eek.r.ser.oir.and Mission Lak..

Aluminium phosphide (AlP) is used as a fumigant and also sometimes misused for.suic.dal attempts in India, due to its easy availability. The effec. of phosphine, the gas that is liber.ted when AlP c.mes in c.ntac. with moistur., is well doc.mented in the liter.tur.. However. the effec. of AlP in its native for. on animal models is not well c.ted. In this study we examined the ac.te toxic.effec. of AlP in r.ts. Or.l LD50 of AlP for.male and female r.ts wer. found to be 14. 13 and 11. 89mg/k., r.spec.ively. Or.l administr.tion of an AlP dose of 0. 80 LD50 r.sulted in signific.nt inc.eases in the level of plasma glutamic.oxaloac.tic.tr.nsaminase,alk.line phosphatase, gluc.se and ur.a in r.ts of both sexes. Hemoglobin level and pac.ed c.ll volume also inc.eased signific.ntly 6h after.administr.tion. Body weight was r.duc.d but the or.an to body weight r.tio of lung, liver. spleen, k.dney and testes r.mained *** c.anges induc.d by AlP dur.ng 24-48h induc.d hemor.hage, c.ngestion and mild to moder.te atr.phy of var.ous c.llular.c.mponents of visc.r.l or.ans. The study showed that the ac.te toxic.effec. of AlP may be due to hypovolemic.shoc.. Female r.ts wer. found to be mor. susc.ptible than wer. males.
