1. Damage index analysis of prefabricated segmental bridge columns under cyclic loading
Abstract The damage index is usually applied to evaluate the damage states of bridge structures, which is the basis of structural fragility study. The present study investigates the seismic damage index of the prefabricated segmental bridge columns (PSBC) under cyclic loading by theoretical and numerical analysis. Based on the previous pseudo-static experime

2. Development of truck weight limits for concrete bridges using reliability theory / Aplicação da teoria da confiabilidade na obtenção de limites para o peso de veículos de carga em pontes de concreto
The increase in gross weight limits allowed by Brazilian legislation and the appearance of new truck configurations in last years require the assessment of bridges structural safety when submitted to real traffic. This thesis verifies the performance of the bridges under DER-SP jurisdiction using the reliability index beta and obtains truck weight limits in

3. Folding autonomy of the kringle 4 fragment of human plasminogen.
Kringle 4, an 88-residue plasminogen fragment carrying a lysine-binding site, loses its affinity for lysine-Sepharose upon reductive cleavage of its disulfide bridges. Aerobic incubation of the reduced, denatured fragment results in the rapid restoration of the disulfide bonds with concomitant recovery of lysine-Sepharose affinity. The ability of the unfolde

4. The effect of partial extraction of troponin C on the elementary steps of the cross-bridge cycle in rabbit psoas muscle fibers.
The elementary steps of the cross-bridge cycle in which troponin C (TnC) was partially extracted were investigated by sinusoidal analysis in rabbit psoas muscle fibers. The effects of MgATP and phosphate on the rate constants of exponential processes were studied at 200 mM ionic strength, pCa 4.20, pH 7.00, and at 20 degrees C. The results were analyzed with

5. Force generation and phosphate release steps in skinned rabbit soleus slow-twitch muscle fibers.
The force-generation and phosphate-release steps of the cross-bridge cycle in rabbit soleus slow-twitch muscle fibers (STF) were investigated using sinusoidal analysis, and the results were compared with those of rabbit psoas fast-twitch fibers (FTF). Single fiber preparations were activated at pCa 4.40 and ionic strength 180 mM at 20 degrees C. The effects

6. B----Z DNA conformational changes induced by a family of dinuclear bis(platinum) complexes.
The reactions of bis(platinum) complexes of general formula [(PtClm(NH3)3-m)2(NH2(CH2)nNH2)]2(2-m)+ were studied with poly(dG-dC).poly(dG-dC), poly(dG-m5dC).poly(dG-m5dC) and poly(dG).poly(dC). When m = 0 (Complexes II, n = 2,4) the complexes are saturated 4+ cations capable only of electrostatic interactions with the polynucleotide. Where m = 1 the complexe

7. Aqueous channels within apolar peptide aggregates: solvated helix of the alpha-aminoisobutyric acid (Aib)-containing peptide Boc-(Aib-Ala-Leu)3-Aib-OMe.2H2O.CH3OH in crystals.
Although the peptide Boc-Aib1-Ala2-Leu3-Aib4-Ala5-Leu6-Aib7-Ala8-L eu9-Aib10-OME [with a t-butoxycarbonyl (Boc) blocking group at the amino terminus, a methyl ester (OMe) at the carboxyl terminus, and four alpha-amino-isobutyric (Aib) residues] has a 3-fold repeat of residues, the helix formed by the peptide backbone is irregular. The carboxyl-terminal half
