This is the second part of the final report submitted to the Iowa Department of Transportation. Part 1 contained a comparison of unaged fiber composite and steel dowels and derivation of the appropriate theoretical model for analyzing the results. Part 2 of this final report covers the theoretical and experimental models for accelerated aging of fiber composite reinforcing bars and dowels cast in a concrete environment. Part 2 contains results from testing of unaged and aged fiber composite dowels and steel dowels, in addition to unaged and aged fiber composite reinforcing bars. Additional tests have been performed on unaged dowels (both steel and fibercomposite) to verify results from Part 1 and to keep the testing program consistent. Slight modifications have been made to the dowel specimens presented in Part 1. These modifications are noted in the Section 3.4 of this report. The flexural modulus of elasticity for the FC dowel bar given in Part 1 of the final report (Table 3. 2) was for the incorrect structural shape (non-circular cross section). The value is corrected and given in Part 2 of the final report (Table 3.4 for the.modulus of elasticity supplied by the manufacturer, and Tables 3. 5 and 3. 6 for experimentally determined modulus of elasticities) • The value in Part 1 was not used for any analysis of the FC dowel bars.

BACKGROUND: The risk of osteoporosis and fracture influences the selection of adjuvant endocrine therapy. We analyzed bone mineral density (BMD) in Swiss patients of the Breast International Group (BIG) 1-98 trial [treatment arms: A, tamoxifen (T) for 5 years; B, letrozole (L) for 5 years; C, 2 years of T followed by 3 years of L; D, 2 years of L followed by 3 years of T]. PATIENTS AND METHODS: Dual-energy X-ray absorptiometry (DXA) results were retrospectively collected. Patients without DXA served as control group. Repeated measures models using covariance structures allowing for different times between DXA were used to estimate changes in BMD. Prospectively defined covariates were considered as fixed effects in the multivariable models. RESULTS: Two hundred and sixty-one of 546 patients had one or more DXA with 577 lumbar and 550 hip measurements. Weight, height, prior hormone replacement therapy, and hysterectomy were positively correlated with BMD; the correlation was negative for letrozole arms (B/C/D versus A), known osteoporosis, time on trial, age, chemotherapy, and smoking. Treatment did not influence the occurrence of osteoporosis (T score < -2.5 standard deviation). CONCLUSIONS: All aromatase inhibitor regimens reduced BMD. The sequential schedules were as detrimental for bone density as L monotherapy.
