The article presents the methodology for finding material damping capacity at higher frequency and lower amplitudes. Lamb wave dispersion theory is used for finding the damping capacity of composite material which is used at extensively high frequency applications. The method has been implemented on carbon fiber reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP) plates. The Lam...

Tetrahydrobiopterin (BH(4)) is an essential cofactor for the nitric oxide (NO) synthases and the aromatic amino acid hydroxylases. Insufficient BH(4) has been implicated in various cardiovascular and neurological disorders. GTP cyclohydrolase 1 (GTPCH-1) is the rate-limiting enzyme for de novo biosynthesis of BH(4). The authors have recently shown that the interaction of GTPCH-1 with GTP cycloh...

A radar NDE (nondestructive evaluation) technique using an airborne antenna operating in the far-field condition is developed for detecting damages such as delamination and concrete cracking in GFRP (glass fiber reinforced polymer)-wrapped concrete columns. The far-field airborne radar (FAR) NDE technique is advantageous for distant measurement of bridge columns in practical applications. Far-f...

Fibre-reinforced polymer composites in general, and especially glass fibre-reinforced (GFRP), have increasingly been used recent decades construction. The advantages of GFRP as an alternative construction material are its high strength-to-weight ratio, corrosive resistance, durability, ease installation. main purpose this study is to evaluate the response under dynamic conditions (more specific...

The use of Fiber Reinforced Polymer (FRP) reinforcement is a practical alternative to conventional steel rebars in concrete structures subjected to aggressive environments. The solution is attractive for bridge deck and rail applications, as it eliminates corrosion of the steel reinforcement, which is the major instrument of degradation. Due to the peculiar physical and mechanical characteristi...
