The influence of the alloying and microalloying elements on phase transformation at different cooling rates was studied and the continuous cooling transformation diagrams were plotted. In order to optimize the heat treatment and improve the mechanical properties, the range of cooling rates leading to a fully bainitic microstructure （without ferrite, pearlite and especially without martensite） was determined. Bainite and martensite transformation start temperatures （Bs, Ms） were also established and compared with the values predicted by empirical equations. The important role of precipitates （especially V carbonitride particles） on final microstructure and mechanical properties was assessed.展开更多

Design: Retrospective observational study. Setting: Community rehabilitation hospital affiliated with a university. Participants: A cohort of 173 organ transplant patients admitted consecutively over a four-year period (2004-2008) was compared to a cohort of all rehabilitation patients (n = 9762) admitted to the same inpatient rehab facility during the same period. Interventions: Inpatient rehab program to all participants. Main Outcome Measures: Length of hospital stay, Functional Independence Measure (FIMTM) change (admission-discharge), and rate of discharges to home. Results: Outcomes were measured using components of the FIMTM instrument, admission and discharge data. Chi-square and independent two-sample t-tests were used for statistical analysis. Compared to a general rehabilitation inpatient population, transplant rehabilitation inpatients had: more immediate (TM change (8.9 vs. 20.9, p TM efficiency (1.1 vs. 1.4, p < 0.001);and a higher rate of discharges to home in patients not readmitted to acute care (98.5% vs. 94.5% p < 0.001). Conclusion: Outcomes of rehabilitation in solid organ transplant patients are comparable but not identical to those in other patient groups. Inpatient rehabilitation for transplant patients is therefore fully justifiable and necessary. The ten times higher rate of transplant patient readmission to acute hospital must be communicated, facilitated, accepted and managed within a partnership strategy.展开更多
