to increase the safety of structures against strong ground motions and their life due to environmental issues on the earth and saving in terms of materials, it is necessary to expand and upgrade seismic resistant systems. however, more cost-effective systems which have sufficient influence on the seismic performance of structures and also more compatibility with the regional conditions, will be...

The paper deals with analysis of loading conditions on damping torque coefficient and synchronizing coefficient in SMIB system and design of Delta-Omega type of damping controller for damping of power oscillations in the system. Effect of variation of loading on synchronizing torque and damping torque coefficients has been investigated in detail. A new design approach for optimizing the paramet...

In this study we assessed the effects of antigen exposure in mice pre-sensitized with allergen following viral infection on changes lung function, cellular responses and tight junction expression. Female BALB/c were sensitized to ovalbumin infected influenza A before receiving a second sensitization challenge saline, (OVA) or house dust mite (HDM). Fifteen days post-infection, bronchoalveolar i...

Chia (Salvia hispanica L.) is one of the most important medicinal plants recently introduced to Egyptian cultivation and has significant multiusing in human curing. Fusarium oxysporum, F. roseum, semitectum, solani, Macrophomina phaseolina, Pythium ultimum, Rhizoctonia solani Sclerotinia sclerotiorum were isolated from infected plants, showing root stem rot symptoms collected different localiti...

attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (tpe) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. in order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic modul...
