Impedance and a.c. conductivity studies of Ba(Pr1/2Nb1/2)O3 ceramic

Investigation on Thermal Conductivity and AC Impedance of Graphite Suspension

Over the past decade, some groups have reported that nanofluids, which are liquids containing suspensions of nanoparticles, have substantially higher thermal conductivity than that of the base fluids. However, the reported high thermal conductivity sometimes cannot be reproduced. Theoretically, potential mechanisms leading to this enhancement are still under scrutiny. In this thesis, we present...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

DC and AC Conductivity Studies in Silver FICGlasses

Fast ion conducting (FIC) glasses of composition 66%AgI-[MAg2O-F{(F1)B2O3-(F2)TeO2}] were prepared by melt quenching technique. Here M/F ratio was varied from 0.0 to 2.0 in steps of 0.25 for fixed values of F1& F2. The prepared samples were characterized by X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR) experiments to understand their structure. Electrical studies of the prepared...
