This paper presents investigation carried out, including experimental and numerical studies, on low-rise shear-dominated brick masonry structures for the calculation of force reduction factor R. Basic experimental tests were conducted on masonry constituent materials for mechancial characterization. In-plane quasi-static cyclic tests were conducted on twelve full scale brick masonry walls, to u...

Seismic design modification factors (SDMFs) control the estimated force and displacement to structures during seismic events. codes recommend similar SDMFs for short andlong-span structures. Therefore, this study investigated effect of span length on steel frames with high ductility. For purpose, nine three different lengths 5, 10, 15 m were selected designed according specifications ASCE/SEI 7...

In this paper a simple tool for seismic design of steel structures for a selected ductility level is presented. For this purpose, a consistent set of earthquakes is selected and sorted based on the maximum acceleration of ground surface. The selected records are applied as the base motion to a single-degree-of-freedom system with strain hardening and the maximum response acceleration is determi...

Recombinant coagulation factor VIII (r-VIII SQ) was chemically modified with monomethoxy poly(ethylene glycol) (mPEG). Three mPEG derivatives were used for coupling to the r-VIII SQ lysines, a mixed anhydride of monomethoxy poly(ethylene glycol) succinic acid (mPEG-SAH), monomethoxy poly(ethylene glycol) succinimidyl succinate (mPEG-SS), and monomethoxy poly(ethylene glycol) tresylate (mPEG-TRE...

This study examined the interrelated effect of environmental pH, gelatin backbone modification and crosslinking modality on hydrogel morphology, surface hydrophilicity, in vitro swelling/degradation kinetics, in vitro drug release kinetics and in vivo degradation, inflammatory response and drug release activity. The percent glutaraldehyde fixation had a greater impact on the morphology of the d...
