2 angstrom(2) at 867 degrees C. Both factors contribute to the excellent performance described for this mixed ionic-electronic conductor (MIEC) oxide as anode in single fuel cells. The dilatometric analysis shows a change of slope at around 270 degrees C that can be correlated with this tetragonal-to-cubic phase transition. The obtained thermal expansion coefficient (TEC) in the tetragonal region, between 50 and 270 degrees C is 14.5 x 10(-6) K-1 whereas in the cubic region,
between 270 and 850 degrees C, the TEC is 11.2 x 10(-6) K-1. These figures are comparable Selleckchem SCH727965 to those obtained from the mentioned structural analysis; moreover the TEC for the cubic phase perfectly matches those of the usual electrolytes in a SOFC.

“The aims of this study were to culturally adapt and validate the Persian
version of Foot and Ankle Outcome Score (FAOS) and present data on its psychometric properties for patients with different foot and ankle problems. The Persian version of FAOS Buparlisib in vitro was developed after a standard forward-backward translation and cultural adaptation process. The sample included 93 patients with foot and ankle disorders who were asked to complete two questionnaires: FAOS and Short-Form 36 Health Survey (SF-36). To determine test-retest reliability, 60 randomly chosen patients completed the FAOS again 2 to 6 days after the first administration. Test-retest reliability and internal consistency were assessed using intraclass
correlation coefficient (ICC) and Cronbach’s alpha, respectively. To evaluate convergent and divergent validity of FAOS compared to similar and dissimilar concepts of SF-36, the Spearman’s rank correlation was used. Dimensionality was determined by assessing item-subscale correlation corrected for overlap. The results of test-retest reliability show that all the FAOS subscales have a very high ICC, ranging from 0.92 to 0.96. The minimum Cronbach’s alpha level of 0.70 was exceeded by most subscales. The Spearman’s correlation coefficient for convergent construct validity fell within 0.32 to 0.58 for the main hypotheses presented a priori between FAOS and SF-36 subscales. For dimensionality, the minimum FK506 mw Spearman’s correlation coefficient of 0.40 was exceeded by most items. In conclusion, the results of our study show that the Persian version of FAOS seems to be suitable for Iranian patients with various foot and ankle problems especially lateral ankle sprain. Future studies are needed to establish stronger psychometric properties for patients with different foot and ankle problems.”
