a lithium borate thermoluminescence dosimeter with 0.3 wt% of manganese impurityconcentration was prepared for high dose levels in the range of 1-30 kgy for gamma irradiation applications.the tld reader was used for read out purposes from ambient temperature to about 400°c with a heating rate of 6°c/sec. the pre- and post- irradiation anneal temperature was 300°c for 1.5 and 1 hours respectivel...
In this paper, ferroelectric thin films, described by an ising model in a transverse field, have been studied under the mean-field approximation. We discuss a thin film composed of N-layer film of simple cubic symmetry with nearest-neighbor exchange in which the exchange strength and transverse field are assumed to be different from the bulk values in Ns surface layers, and we derive and illust...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
Ammonium perchlorate (AP) is considered as a strong oxidizer in solid propellants. Therefore, its thermal decomposition characteristics directly influence the combustion behavior of solid propellants. The AP particle size, shape, and morphology influence on the thermal behavior. In this study, the solvent anti-solvent crystallization method equipped with an eductor mixer was used as a system fo...
The aim of the study was to evaluate the effect of storage and temperature on egg physical quality in Hyline chickens line. A total of 150 eggs from College of Natural Resources farm were sampled for the present experiment. About 70 eggs each were stored in home refrigerator (temperature, 7.46±0.23 ˚C; relative humidity, 24.80±0.05%) and room temperature (temperature, 22.98±1.12 ˚C; relative hu...
The temperature dependence of Coulomb blockade peak height correlation is used to investigate how adding electrons to a quantum dot alters or “scrambles” its electronic spectrum. Deviations from finite-temperature random matrix theory with an unchanging spectrum indicate spectral scrambling after a small number of electrons are added. Enhanced peak-to-peak correlations at low temperature are ob...
