This article explores the rationales for creating specific top level domain (TLD) names to support minority languages and cultures, focussing specifically on the case for a TLD .cy or .cym for Wales. Some background information on domain names and Wales and the Welsh language is provided. Following on from this, the way identity may be constructed is explored and the importance of TLD’s in term...

LiF, Mg and Ti cubical TLD chips (known as TLD-100) are widely used for dosimetry purposes. The repeatability of TL dosimetry is investigated by exposing them to doses of (81, 162 and 40.5 mGy) with 662keV photons of Cs-137. A group of 40 cubical TLD chips was randomly selected from a batch and the values of Element Correction Coefficient (ECC) were obtained 4 times by irradiating them to doses...

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 ...
