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) ...
Ac susceptibility studies of discontinuous Co80Fe20Al2O3 multilayers
Discontinuous metal}insulator multilayers [Co Fe (t)/Al O (3 nm)] are prepared by ion-beam sputtering and investigated by SQUID magnetometry and AC susceptometry. For 1.0)t)1.6 nm, two coexisting subsystems of dipolar coupled nanoparticles are encountered. While a spin-glass-like freezing particulate fraction dominates at t"1.0 nm, a percolating dipolar ferromagnetic fraction becomes increasing...
متن کاملCompact Ac(σ) Operators
All compact AC(σ) operators have a representation analogous to that for compact normal operators. As a partial converse we obtain conditions which allow one to construct a large number of such operators. Using the results in the paper, we answer a number of questions about the decomposition of a compact AC(σ) into real and imaginary parts.
متن کاملDC 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...
متن کاملEvaluation of anticorrosion behavior of automotive electrocoating primers by the AC-DC-AC accelerated test method
A protective coating has been applied onto the phosphated panels using cathodic electrocoating in two different dry film thickness namely 8µm and 20µm. The corrosion resistance of cathodic electrocoatings has been studied using AC/DC/AC method. Twelve cycles of AC/DC/AC test were carried out on each sample which the DC voltage of the first 6 cycles were -4 V VS. Ag/AgCl @ 20 minutes followed by...
