Lead-rubber seismic isolation bearings (LRB) have been installed in a number of essential and critical structures, like hospitals, universities bridges, located earthquake-prone areas. The purpose using LRB is providing the structure with period lengthening capacity dissipating considerable amount earthquake energy to mitigate effects strong ground motions. Therefore, studying damage mechanics ...

Strong motion recordings from four seismically isolated buildings are used in time-invariant and time-variant modal identification analyses. The buildings are identified as equivalent, time-varying, linear dynamic systems characterized by their time-varying modal parameters (including fundamental-mode natural frequencies, damping ratios, and mode shapes). The identification analyses for each si...

Germ-free rodents colonized with microbiotas of interest are used for host-microbiota investigations and for testing microbiota-targeted therapeutic candidates. Traditionally, isolators are used for housing such gnotobiotic rodents due to optimal protection from the environment, but research groups focused on the microbiome are increasingly combining or substituting isolator housing with indivi...

In the paper, the Electrorheological fluid(ERF) is embedded in the pneumatic vibration isolator and three kinds of control systems are designed, which experimental results are also compared. The first kind of the control system is the semi-active control system, which is designed for ERF controllable damper. The second kind of the control system is the active control system, which is designed f...

The testing of the H2O2 decontamination process using spores of Bacillus stearothermophilus has gained widespread acceptance. Usually, commercially available Biological Indicators (BIs) with a specified resistance to H2O2 are challenged to qualify the process. The question arises whether the resistance of test spores is dependant on the type of carrier material and whether the resistance is rep...

Optical detection has long been the most popular technique in immunosensing. Recent developments in the synthesis of luminescent probes and the fabrication of novel nanostructures enable more sensitive and efficient optical detection, which can be miniaturized and integrated with microfluidics to realize compact lab-on-a-chip immunosensors. These immunosensors are portable, economical and autom...

www.pharmtech.com he number of parenteral products entering development and reaching the market has increased significantly during the past decade. By some estimates as many as half of all investigational new drug applications consist of biopharmaceuticals, the vast majority of which are manufactured aseptically. Most of these products are proteins and therefore highly susceptible to microbial ...
