The dyadic Green's function for cylindrical waveguides of circular or rectangular cross section with a moving, isotropic, homogeneous medium is developed using the method of eigenfunction expansion. The orthogonality properties of the vector mode functions are discussed. In contrast to waveguides with a stationary medium, it is seen that the normalization factor in the case of the E mode introd...

In the present paper, we report the indigenous development of a neutron-sensitive thermoluminescent dosemeter (TLD) based on CaSO4:Dy Teflon TL disc. The study includes indigenous development of a neutron dosemeter and its response in terms of operational quantity to different energies of neutrons under various irradiation conditions. It was found that the thermal neutron sensitivity of the CaS...

When grown in thymine-free minimal synthetic medium, thyA recA mutants of Escherichia coli K12 were comparatively more resistant and thyA recBC mutants more sensitive to thymineless death (TLD) than their respective parent strains. No excessive numbers of single-strand breaks were observed in the DNA of the recBC mutant strain starved for thymine, hence the hypersensitivity for TLD in this stra...

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...
