one important application of fiber reinforced polymer (frp) is to confine concrete as frp jackets in seismic retrofit process of reinforced concrete structures. confinement can improve concrete properties such as compressive strength and ultimate axial strain. for the safe and economic design of frp jackets, the stress-strain behavior of frp-confined concrete under monotonic and cyclic compress...

Loading can increase bone mass and size and this response is reduced with aging. It is unclear, however how loading affects bone mineral and matrix properties. Fourier transform infrared imaging and high resolution synchrotron scanning small angle X-ray scattering were used to study how bone's microscale and nanoscale compositional properties were altered in the tibial midshaft of young, adult,...

impact is one of the most important subjects which always have been considered in mechanical science. nature of impact is such that which makes its control a hard task. therefore it is required to adopt a safe and secure mechanism for transferring the impact to other vulnerable parts of a structure, when it is necessary. one of the best methods of absorbing impact energy is using thin-walled tu...

conclusions off-loading shoes are suitable modalities to treat forefoot fractures. although no statistically significant difference was found between the groups, but due to the comparable outcomes, high patient satisfaction, and lack of complications, nonoperative treatment of forefoot fractures using off-loading shoes is recommended. results clinical and radiological :union:s were achieved in ...

the goal of this research is to determine the feasibility of loading rifampin into mesoporous silica nanoparticles. rifampin was selected as a model lipophilic molecule since it is a well-documented and much used anti tuberculosis drug. the mesoporous silica nanoparticles were prepared by using tetraethyl ortho silicate and cetyltrimethyl ammonium bromide (as surfactant); the prepared nanoparti...

monthly and annual water and phosphorus mass budgets were set up over the year 2010 for thelake rio verde, brazil. limited data for the water budget was compensated using an interpolation methodwith data water budget data of a nearby reservoir. thus, errors of ca. 1.5% were estimated for the waterbudgets. dominant p mass input terms were inflows from the rivers and direct run off into the reser...
