beryllium  oxide  (beo)  nanopowder  was  synthesized  using  sol-gel method  and  the  effects  of  changes of  chemical  reagents  were investigated.  because  of  tissue  equivalence  and  other  outstanding thermoluminescence  (tl) properties of  the bulk material  in x and γ dosimetry, the applicability of this nanostructure in tl dosimetry was studied  following  irradiation to  the 137 c...

Despite a widespread interest in the warm glow model [Andreoni (1989,1990)], surprisingly most attention focused on the voluntary contribution equilibrium of the model, and only very little attention has been devoted to the competitive equilibrium. In this paper, we introduce the notion of competitive equilibrium for a warm glow economy [Henceforth, warm glow equilibrium]. Then, we establish (a...

We introduce Glow Clustering, a clustering technique inspired by the physics of light and the images of spiral galaxies. We discuss the genesis, design, and implementation of Glow Clustering. We evaluate Glow Clustering on test datasets and a well-known standard dataset. Finally, we attempt to describe the characteristics of Glow Clustering, giving some insight into the context of use where Glo...

Thermoluminecsence (TL) characteristics of pure CaSO4 nanoparticles produced by co-precipitation method are presented. The formation of the nanoparticles was confirmed by X-ray diffraction (XRD) and scanning electron microscope (SEM). TL glow curve of this phosphor, exposed to gamma radiation exhibits five overlapping glow peaks in the complex glow curve at 463, 470, 483, 498 and521(K) respecti...

Silicate minerals are therefore isolated from the foodstuffs, mostly by a density separation step. In order not to obscure the TL, the isolated silicate minerals should be as free of organic constituents as possible. A first glow of the separated mineral extracts is recorded (Glow 1). Since various amounts and/or types of minerals (quartz, feldspar etc.) exhibit very variable integrated TL inte...

an improved mixed order model is presented to describe the thermolumunescence (tl) glow peaks. in this model a fraction of charge carriers, which undergo nonradiative recombination following thermal excitation is taken into account. therefore, it is expected that the proposed model will produce more realistic kinetic parameters than that of mixed order model. the tl glow curves generated by the...

The family replication problem is addressed in the context of the dual standard model. The breaking of a simple grand unified group to [Glow × H1 × H2 × H3]/Z 3 5 and then further to Glow, produces a spectrum of stable monopoles that fall in three families each of whose magnetic quantum numbers correspond to the electric charges on the fermions of the Standard Model. Here Glow = [SU(3)×SU(2)×U(...

The thermoluminescence (TL) glow curves of UV irradiated PAAm-PVA polyblend have been studied. The experimental glow curves show the presence of two peaks with glow peak temperatures at 373K and 479K. The values of activation energy and frequency factors are determined by employing computer simulation. Most of the TL glow curves obey non first order kinetics. The results obtained by using TL ex...

The linearity of thermoluminescence (TL) dose response curve, in low dose levels, is affected by background signals appearing at the tail of the glow curves. The effects of these signals also restrict the use of the high temperature glow peaks in many applications. In this study, a new reading out procedure was presented to reduce the background signals and increase the resolution of the high t...
