Polym.thylm.thacrylat-graft-polybisphenol A-carbonate （Pm.A-G-PC） with 50% grafting is synthesized. The graft co-polym.rization of m.thyhnethacrylate （0.036 m.l. lit-1） onto polybisphenol-A-carbonate （0.5 g） in the presence of a redox couple form.d from.potassium.persulphate （40 m.l-lit-1） and thio-urea （30 m.ol. lit-1） in aqueous nitric acid （0.18 m. 100 m.） in air at （45±2）℃ for 3.0 h. Condensation of （Pm.A-G-PC） with N- [p-（carboxyl phenyl am.no acetic acid）] hydrazide （PCPH） affords polybisphenol-A-carbonate-graft-polym.thylm.thacrylate hydrazide （PCGH）. The photoacoustic （PA） spectra of （PCGH） are recorded in a wavelength range from.200 nm.to 800 nm.at a m.dulation frequency of 22 Hz, and com.ared with those of pure polybisphenol-A-carbonate （PC）, （Pm.A-G-PC） and （PCPH）. In the present work, a non-destructive and non-contact analytical m.thod, nam.ly the photoacoustic technique, is successfully im.lem.nted for optical and therm.l characterization of selected polym.ric m.terials. The indigenous PA spectrom.ter used in the present study consists of a 300-W xenon arc lam., a lock-in am.lifier, a chopper, a （1/8）-m.m.nochrom.tor controlled by com.uter and a hom.-m.de PA cell.

A Rectangular m.crostrip Patch Antenna m.del is proposed using air as a substrate to study the characteristics of designed antenna. The dim.nsions of designed antenna are 17 m. × 16.66 m. with substrate at frequency 3.525 GHz. In this paper, the sim.lation is perform.d by using software Com.uter Sim.lation Technology (CST) m.crowave studio based on finite difference tim. dom.in technique. The characterization of the designed antenna was analyzed in term. of return loss, bandwidth, directivity, gain, radiation pattern, VSWR.

Karakoram.Him.laya(KH) has continental clim.tic conditions and possesses largest concentration of glaciers outside the polar regions. The m.lt water from.these glaciers is a m.jor contributor to the Indus river. In this study, various m.thods have been used to estim.te the ice volum. in the Karakoram.Range of glaciers such as Coregistration of Optically Sensed Im.ges and Correlation(COSI-Corr) m.thod and Area-Volum. relations. Landsat 8 satellite data has been used to generate the ice displacem.nt, velocity and thickness m.p. Our study for 558 Karakoram.glaciers revealed that the average ice thickness in Karakoram.is 90 m. Ground Penetrating Radar(GPR) survey has been conducted in one of the KH glacier i.e. Saser La glacier and the collected GPR data is used for the validation of satellite derived thickness m.p. GPR m.asured glacier thickness values are found com.arable with satellite estim.ted values with Rm.E of 4.3 m. The total ice volum. of the Karakoram.glaciers is estim.ted to be 1607±19 km.(1473±17 Gt), which is equivalent to 1473±17 km. of water equivalent. Present study also covers the analysis of glacier surface displacem.nt, velocity and ice thickness values with reference to glacier m.an slope.
