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. ...

The present research was conducted to investigate the effect of sill geometry and width on discharge coefficient hydraulic jump characteristics. For this purpose, sills with semi-cylindrical, cylindrical, pyramidal, rectangular cube geometries widths 0.075, 0.10, 0.15, 0.2 m were installed under a sluice gate. Results showed that increasing increased gate compared no-sill mode. results placing ...

In this paper, we introduce a novel cylindrical channel that generates coaxial flow without using glass microcapillary or complicated silicon processing, and we demonstrate the fabrication of microparticles and microfibers using this channel. The simple fabrication process for cylindrical channels employs the deflection of free-standing thin PDMS membranes. Using this channel, alginate micropar...

This paper presents the boundary integral equation method (BIEM) for stress intensity factors and elasticity T-stresses evaluation in 3D problems. Flat rectangular, elliptic, penny-shaped cracks rectangular crack on a cylindrical surface have been investigated. The hyper-singular integrals are treated with Taylor’s series expansion of kernel, Chebyshev polynomials second kind used to solve equa...

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...

Background and purpose: European Society for Therapeutic Radiology and Oncology (ESTRO) has set up a Quality Assurance network for radiotherapy (EQUAL) carrying out dosimetry audit. Some of the work is done in cooperation with the IAEA. The network deals with measurements performed with mailed TLD irradiated in reference and non-reference conditions, for on-axis points in photons and electrons ...

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 ...
