thermoluminescent detector/LiF:Mg,Ti/glow curve deconvolution/annealing/NIRS-HIMAC The stability of glow peaks in LiF:Mg,Ti (TLD-600) exposed to a high-energy Fe-ion beam was examined in comparison to Cs γ -ray irradiation under changing annealing conditions. The peak areas induced by the Fe ions were much smaller than those by γ -rays. The sizes and positions of peaks 3–5 in Fe-ion irradiated ...

With interest in the potential of optical fibres as the basis of next-generation thermoluminescence dosimeters (TLDs), the development of suitable forms of material and their fabrication has become a fast-growing endeavour. Present study focuses on three types of Ge-doped optical fibres with different structural arrangements and/or shapes, namely conventional cylindrical fibre, capillary fibre,...

T h e r m a l desorption spectroscopy (TDS) based on the mass spectroscopy of thermal ly evolved hydrogen is used for desorption analysis of amorphous hydrogenated silicon (a-Si:H). Two series of glow discharge chemical vapour deposited a-Si:H were investigated by the T D S method . Cons tan t t e m p e r a t u r e growth ra te enabled to determine t empera tu re regions of hydrogen evolution a...

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...

Abstract In the present work, we have synthesized Europium (Eu) doped Tristrontium Dialuminium Oxide (Sr 3 Al 2 O 6 :Eu) phosphor by solid state reaction method in air atmosphere. The thermoluminescence (TL) properties of are investigated and presented. Theoretical analysis glow curves Sr :Eu was done computerized curve deconvolution (GCD) method, trapping parameters phosphor, such as activatio...
