As part of a larger project to investigate the use of Fiber-Reinforced Polymer (FRP) materials in bridge construction, a short-span FRP-reinforced concrete bridge was installed in central Missouri. The Walters Street Bridge is a precast concrete panel bridge reinforced with both glass FRP (GFRP) and carbon FRP (CFRP) reinforcing bars. It was designed according to the American Concrete Institute...

4 FRP strengthening systems for infill masonry walls are typically designed to resist flexural stresses due to out-of5 plane pressure. Previous research has shown that there are potential premature failure mechanisms due to shear 6 sliding of the infill, which could reduce the effectiveness of the strengthening system. Current design guidelines for 7 strengthening of masonry walls with fiber-re...

OBJECTIVE To assess the clinical benefit of either metronidazole and amoxicillin or doxycycline administered immediately after completion of full-mouth scaling and root planing (FRP) for treatment of generalized aggressive periodontitis. METHODS Patients, 18 to 40 years of age, referred to the Karadeniz Technical University department of periodontology between January 2009 and September 2009 ...

[1] Instantaneous estimates of the power released by a fire (Fire Radiative Power, FRP) are available with satellite active fire detection products. Integrating FRP in time provides an estimate of the total energy released (Fire Radiative Energy, FRE), which can be converted into burned biomass estimates needed by the atmospheric emissions modeling community. While straightforward in theory, th...

در این مقاله، به بررسی اثر پارامترهای گوناگون بر شکل تپ‌های گسیلی لیزر 2CO تپی پرداخته شده است. راستا، عوامل مختلفی مانند: فشار گاز و هم‌­چنین طول تشدیدگر تغییر داده شدند هر حالت به‌همراه اندازه انرژی آن‌ها ثبت گردیدند. نتایج نشان می‌­دهد که با افزایش گاز، به‌شدت می‌یابد، به‌گونه‌ای 2 برابر 3 شدن فشار، 5 برابر، پهنای زمانی تپ‌ها نیم یک‌سوم زمان برساخت آن‌­ها نیز 9/0 7/0 اندازه‌های اولیه‌ی خود م...
