Highlights 2 Single phase LaTi2Al9O19 (LTA) has been successfully synthesized by sol-gel method at relatively low temperature (1350 o C), something not previously investigated. The sol-gel synthesized LTA shows good thermochemical stability up to 1500 o C. Sol-gel synthesized LTA shows higher coefficients of thermal expansion than the solid state reaction synthesized LTA. LTA is a face ...
Protein A of Staphylococcus aureus is a pathogenic factor whose encoding gene, spa, shows a variation in length in different strains. In this study the spa gene variation in S. aureus isolated from healthy carriers and patients was studied, We also compared this variation among MRSA with MSSA strains. 208 strains of Staphylococcus aureus which we were isolated from Gorgan, north of Iran were st...
Soo-Kwan Jang Choon-Sang Park Heung-Sik Tae (SID Member) Bhum Jae Shin (SID Member) Jeong Hyun Seo (SID Member) Eun-Young Jung Abstract — To investigate the influence of the gas condition, especially xenon (Xe) gas, on the wallvoltage variation in relation to the electric-field intensity during the address period, the wall voltages were measured under various Xe-gas content ranging from 11 to 2...
We analyzed the characteristics of white porcelain fired at different temperatures (800, 1200, 1350℃) by measuring changes in thermal luminescence(TL) and multi-wavelength (IR, orange, green, blue, UVA) optically stimulated luminescence(OSL) signal. White 800℃ showed high intensity TL signals over a wide temperature range 100 to 400℃, whereas 1200 1350℃ peaks 210℃. Moreover, OSL 800℃, increased...
