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...

The Last Refuge of a Scoundrel? Patriotism and Tax Compliance We study the effects of patriotism on tax compliance. In particular, we assume that individuals feel a (random draw of) warm glow from honestly paying their taxes. A higher expected warm glow reduces the government's optimal audit probability and yields higher tax compliance. Second, individuals with higher warm glow are less likely ...

A model for negative glow metal-vapor ion lasers that self-consistently describes the dynamics of the negative glow and the cathode sheath regions of the discharge has been developed. The model computes the electron energy distribution and the population of relevant excited states in the negative glow self-consistently with the charged particle fluxes and electric field distribution in the cath...

Calcium fluoride nanoparticles doped with thulium and cerium were synthesized as a novel nanostructure by using the hydrothermal method. The prepared samples were characterized by X-ray diffraction (XRD) and energy dispersive spectrometer (EDS). The crystallite size of about 36 nm was estimated employing Scherer’s formula. Its shape and size were also observed by scanning electron microscope (...

Criticism of contingent valuation (CV) stresses warm glow and free-riding as possible causes for biased willingness to pay figures. We present an empirical framework to study the existence of warm glow and free-riding in hypothetical WTP answers based on a CV survey for the measurement of health-related Red Cross services. Both in conventional double-bounded and spike models we do not find indi...

The thermoluminescence (TL) glow peaks of nanoparticles was simulated by a the Monte Carlo method in which all the ordinary as well as anomalous transitions between the nanoparticle clusters are taken into account. The adjustable parameters are activation energy and frequency factor of the trap, both   radiative and nonradiative recombination, direct recombination from trap to recombi...

The irradiation effect of argon, oxygen glow discharge plasma, and mercury lamp on silver and agar/silver nanoparticle samples is studied. The irradiation time dependence of the synthesized silver and agar/silver nanoparticle absorption spectra and their antibacterial effect are studied and compared. In the agar/silver nanoparticle sample, as the irradiation time of argon glow discharge plasma ...

BACKGROUND Hypochondriacal attitudes were associated with cognitions not related to illness: Social fears, low self-esteem, and reduced warm glow effect, i.e. less positive appraisal of familiar stimuli. Only a single study had investigated the correlation of hypochondriacal attitudes with the warm glow effect so far and the present study aimed to corroborate this association. Particularly, the...

The thermoluminescence (TL) glow curves and kinetics parameters of Thulium (Tm) doped silica cylindrical fibers (CF) are presented. A linear accelerator (LINAC) was used to deliver high-energy radiation of 21MeV electrons and 10MV photons. The CFs were irradiated in the dose range of 0.2-10Gy. The experimental glow curve data was reconstructed by using WinREMS. The WinGCF software was used for ...

Quartz obtained from structural materials (bricks, tiles, etc.) is usually employed in retrospective accident dosimetry using the thermoluminescence (TL) technique. However, the TL response can be different depending on the sample due to the different concentration of the impurities in quartz lattice and the glow curves themselves show an enormous variety of shapes. In order to investigate the ...
