In the field of thermoluminescence dosimetry the daily analysis of multi-peak glow curves includes computerized curve-fitting methods, the so-called deconvolutions. These are in need of restricting the kinetic parameters E and s in order to obtain physically relevant results. There have been suggested various methods for the determination of these kinetic parameters based on a theory treating s...

Cases involving high-doses of ionizing radiation are becoming increasingly common.The objective of this work was to characterize thermoluminescent materials for the dosimetry of workers exposed to high doses. Samples of TLD-200, TLD-400 and TLD-800 pellets from Thermo Electron Corporation were studied in gamma high-doses. Dose-response curves were obtained for doses between 100 mGy and 100 Gy. ...

Background: the narrative abilities provide valuable information about the linguistic, cognitive and social development of school-age children with typical language development (TLD). Aim: to examine the temporal ordering of figures and the narrative abilities of school-age children with TLD in relation to the type of discourse presented. Method: participants of this study included 60 children ...

The application of trilinear decomposition (TLD) to the analysis of fluorescence excitation-emission matrices of mixtures of polycyclic aromatic hydrocarbons (PAHs) is described. The variables constituting the third-order tensor are excitation wavelength, emission wavelength, and concentration of a fluorescence quencher (nitromethane). The addition of a quencher to PAH mixtures selectively redu...

The purpose of this study was to determine the dose to the contralateral breast during accelerated partial breast irradiation (APBI) and to compare it to external beam-published values. Thermoluminescent dosimeter (TLD) packets were used to measure the dose to the most medial aspect of the contralateral breast during APBI simulation, daily quality assurance (QA), and treatment. All patients in ...

In immunocompetent individuals, the stability of the herpesvirus-host balance limits opportunities to study the disappearance of a virus-specific CD8(+) T-cell response. However, we noticed that in HLA-A 0201-positive infectious mononucleosis (IM) patients undergoing primary Epstein-Barr virus (EBV) infection, the initial CD8 response targets three EBV lytic antigen-derived epitopes, YVLDHLIVV ...

DNS is a critical infrastructure of the global Internet. To assure DNS’s efficient and robust operations, each domain, especially each of the Top-Level-Domains (TLDs), should deploy multiple redundant nameservers in diverse locations. To assess the robustness of TLD nameserver deployment regarding the nameserver redundancy and location diversity, we conduct a measurement study by sending specia...
