Pure an. An.imon. (Sb, x = 0.01%, 0.02% an. 0.03%) doped Bi0.5n.0.5TiO3 electro ceramics were successfully syn.hesized by a con.en.ion.l solid state reaction.route.

The data show the Loren.zian.decon.olution.of the 002 an. 200 peak. of the tetragon.l phase an. the 202 peak.of the rhombohedral phase. There is n. sign.fican. chan.e in.the Raman.spectra for the prepared composition. while some addition.l peak. aroun. 151, 281, 585 an. 853 cm-1 compared to the peak. observed in.Bn..

As a part of our systematic study of the physical properties of the compoun.s of symmetric liquid crystal dimer homologous series, α,ω-bis-(4-n.alk.lan.lin. ben.yliden.-4’-oxy) alk.n.s (***.m), we report here an.optical study of two n.matogen.c compoun.s of this series viz., 6.O12O.6 an. 7.O12O.7 by carryin. out the measuremen. of extraordin.ry an. ordin.ry refractive in.ices usin. modified spectrometer. The molecular polarizability an.sotropies are evaluated usin. Lippin.ott δ-fun.tion.model, the molecular vibration.method, Haller’s extrapolation.method an. scalin. factor method. The molecular polrizabilities, αe an. αo are calculated usin. Vuk.’ isotropic field model an. n.ugebauer’s an.sotropic field model. The orien.ation.l order parameter, S, is estimated by usin. the molecular polarizability values calculated from refractive in.ex an. den.tity data as well as polarizability an.sotropy values calculated as a fun.tion.of temperature in.the n.matic phase of both of the dimers. These values are discussed with referen.e to the order parameter values obtain.d directly from the optical birefrin.en.e, Δn. data without assumin. an. in.ern.l field. A comparison.of the order parameter values from all of these methods was carried out in.the light of available literature data.

In.view of the difficulties in.stan. volume estimation.in.n.tural forests, we derived real form factors an. models for volume estimation.in.these types of forest ecosystems, usin. k.tarn.aghat Wildlife San.tuary as a case study. Tree growth data were obtain.d for all trees （dbh 〉10 cm） in.4 plots （25 × 25 m） ran.omly located in.each of three strata selected in.the forest. The form factor calculated for the stan. was 0.42 an. a ran.e of 0.42 0.57 was estimated for selected species （den.ity 〉10）. The parameters of model variables were con.isten. with gen.ral growth tren.s of trees an. each was statistically sign.fican.. There was n. sign.fican. differen.e （p〉0.05） between.the observed an. predicted volumes for all models an. there was very high correlation.between.observed an. predicted volumes. The output of the performan.e statistics an. the logical sign. of the regression.coefficien.s of the models demon.trated that they are useful for volume estimation.with min.mal error. Plottin. the biases with respect to con.iderable regressor variables showed n. mean.n.ful an. eviden. tren. of bias values alon. with the in.epen.en. variables. This showed that the models did n.t violate regression.assumption. an. there were n. heteroscedacity or multiculn.rity problems. We recommen. use of the form factors an. models in.this ecosystem an. in.similar on.s for stan. an. tree volume estimation.

Man.-Raigarh coalfield is on. of the largest coalfields in.the Mahan.di basin. The Geological Survey of In.ia carried out in.tial study primarily on.exploration. However, detailed petrographic an. geochemical characters of the coals have n.t been.don. so far. This in.estigation.is an.attempt for petrographic an. geochemical appraisal of the coals. Moreover, effort is also made for possible in.erpretation.on.developmen. of coal facies. The results drawn.from 30 composite coal samples suggest coals are rich in.vitrin.te, with collotelin.te as the domin.n. maceral while liptin.te macerals register low con.en.ration. Domin.n. min.ral assemblages foun. were clay min.rals, pyrite was recorded as dissemin.ted, framboidal an. euhedral forms, carbon.tes recorded were main.y siderites. The vitrin.te reflectan.e ran.om （VRo） mean.values ran.e from 0.44 % to 0.56 %, an. the ran.0}of coal is suggested as high volatile ＇B＇ to ＇A＇ sub- bitumin.us in.ran.0} The rock.eval pyrolysis reveal TOC con.en. varyin. from 37 % to 68.83 %, while low hydrocarbon.gen.ratin. poten.ial is eviden. from low $2 an. Tmax values. The Hydrogen.In.ex （HI） versus Oxygen.In.ex （OI） plot reveal that the samples belon. to k.rogen.type--II-III with in.ut domin.n.ly from terrestrial source, some samples also fall in.k.rogen.type--II domain.in.icatin. lacustrin. in.ut. Vitrin.te reflectan.e result in.icate that the samples are immature an. approachin. oil win.ow, which is in.agreemen. with data of the Rock.Eval parameters. The gelification.in.ex （GI） an. tissue preservation.in.ex （TPI） in.icate that the coal developed in.a telematic set up with high tree den.ity. The groun. water in.ex （GWI） an. vegetation.in.ex （VI） demon.trate that the peat developed as an.ombrogen.us bog.
