Generalized pole figures from post-processing whole Debye-Scherrer patterns for microstructural analysis on deformed materials.

Debye-Scherrer patterns, obtained from X-ray diffraction experiments using synchrotron light in transmission geometry, were analysed to construct generalized pole figures, and further used as input for an orientation distribution function inversion algorithm. By using Langford's method for separating strain and size contributions to peak broadening, it was possible, for the first time, to obtain full domain size and dislocation density generalized distribution functions (GDFs). This method was applied to cold-rolled and annealed interstitial-free steel.

Factors affecting Confidence Index in EBSD analysis.

Automated EBSD analysis systems have been used for over two decades relying on the fact that the correctness of a particular orientation solution could be assessed through the calculation of a Confidence Index. However, such an index only reports whether a particular solution stands out among any other possible solutions, by receiving a larger number of votes than others, and does not necessarily imply that the corresponding orientation is correct. This issue is addressed in the present paper, where the correctness of solutions and the factors that might affect it have been studied for single crystal Si and polycrystalline Zn.

Effect of Tolrestat on oesophageal transit time and cholecystic motility in type 2 diabetic patients with asymptomatic diabetic neuropathy.

The aim of the present study was to investigate the influence of Tolrestat, an aldose-reductase inhibitor, on both oesophageal and cholecystic motility in Type-2 diabetic patients with asymptomatic diabetic neuropathy. Sixty-six patients were randomly assigned to receive Tolrestat 200 mg once daily (33 patients) or were left without specific treatment (33 patients) for 12 months. Efficacy and safety evaluation were done at 4.
