Air kerma data and the relative response of the new HPA TLD are calculated for Narrow Series X-ray distribution and Cs photon sources using the general purpose Monte Carlo code MCNP5, and the results are compared to those obtained using its predecessor, MCNP4c2. It is found that the results differ at low energies (< 0.1 MeV) by up to ~10 %. This disparity is mainly ascribed to differences in th...

Abstract. The recent experimental data obtained by the OBELIX group on total p̄p annihilation cross section are analysed; the low energy spin averaged parameters of the p̄p scattering amplitude (the imaginary parts of the S-wave scattering length and P-wave scattering volume) are extracted from the data. Their values are found to be equal to Imasc = −0.69±0.01(stat)±0.03(sys) fm, ImAsc = −0.76±0....

The paper compares the processes used at ITU for the fabrication of americium targets for transmutation: powder mixing process, sol-gel method and the infiltration by an active solution of inactive pellets. The advantages of the latter processes, related mainly to the lower level of dust formation, are stressed. Moreover, the radiological constraints on the fabrication as a function of Am conte...

Response We are able to compare our spectrum of travellers to the WTO travel statistics for Switzerland and to European airport studies. From there, we know that travellers to North Africa, the Middle East and the Caribbean region are underrepresented as we have highlighted in the DISCUSSION section. In addition, we have specified the manuscript title to clearly state that only travellers to re...

We determine the shape of the strongest column in the class of columns of length I, volume V, and having similar cross-sectional areas A (x) satisfying a < A(x) < b where a and 6 are prescribed positive bounds. In the special case where there are no constraints on the areas of cross-sections the problem has been solved by Keller [1] and by Takjbakhsh and Keller [2]. These authors observed that ...

Tomographic imaging is a technique for exploration of a cross-section of an inspected object without destruction. Normally, the input data, known as the projections, are gathered by repeatedly radiating coherent waveform through the object in a number of viewpoints, and receiving by an array of corresponding detector in the opposite position. In this research, as a replacement of radiographs, t...

This article provides tools for characterizing the extent of cross-section correlation in panel data when we do not know a priori how many and which series are correlated. Our tests are based on the probability integral transformation of the ordered correlations. We first split the transformed correlations by their size into two groups, then evaluate the variance ratio of the two subsamples. Th...

The first data on bottom quark production in pp̄ collisions at 1.96 TeV have recently been obtained by the CDF collaboration. These data probe the region of pT ∼ 0, providing a new invaluable input on the issue of the compatibility between next-to-leadingorder (NLO) QCD and data. We reconsider the evaluation of the b cross section, in view of recent theoretical developments, and of the latest in...
