Ferritin synthesis is controlled at the translational level in response to cellular iron status. A component of this regulatory system is the ferritin repressor protein (FRP) which binds to the iron-responsive element (IRE) located at the 5' end of all known ferritin mRNAs, thus inhibiting its translation. Antibodies against purified FRP were raised in mouse and used to isolate an FRP cDNA from...

Vibrio harveyi NADPH:FMN oxidoreductase P (FRP(Vh)) is a homodimeric enzyme having a bound FMN per enzyme monomer. The bound FMN functions as a cofactor of FRP(Vh) in transferring reducing equivalents from NADPH to a flavin substrate in the absence of V. harveyi luciferase but as a substrate for FRP(Vh) in the luciferase-coupled bioluminescent reaction. As part of an integral plan to elucidate ...

Fiber Reinforced Polymer (FRP) bridge systems are gaining wide acceptance among bridge engineers. At the same time, FRP bridge systems are relatively expensive when compared to traditional reinforced concrete bridge systems. In this study, the concept of the hybrid FRP-concrete structural systems is applied to a bridge superstructure. The hybrid FRP-concrete superstructure system is intended to...

Vibrio harveyi luciferase and flavin reductase FRP are, together, a two-component monooxygenase couple. The reduced flavin mononucleotide (FMNH2) generated by FRP must be supplied, through either free diffusion or direct transfer, to luciferase as a substrate. In contrast, single-component bifunctional monooxygenases each contains a bound flavin cofactor and does not require any flavin addition...

In this paper, we demonstrate how Functional Reactive Programming (FRP), a framework for the description of interactive systems, can be extended to encompass parallel systems. FRP is based on Haskell, a purely functional programming language, and incorporates the concepts of time variation and reactivity. Parallel FRP serves as a declarative system model that may be transformed into a parallel ...

The behavior of concrete-filled fiber tubes (CFFT) polymers under axial compressive loading was investigated. Unlike the traditional fiber reinforced polymers (FRP) such as carbon, glass, aramid, etc., the FRP tubes in this study were designed using large rupture strains FRP which are made of recycled materials such as plastic bottles; hence, large rupture strain (LRS) FRP composites are enviro...

The concept of an integrated strengthening and damping retrofit system was proposed to design reinforced concrete (RC) columns for their optimal performance under multi-level earthquake hazards. As illustrated in Figure 1, the system consisted of fiber reinforced polymer (FRP) sheets wrapping around a column and viscoelastic (VE) layers on the FRP sheets. The motion of the outer surface of the ...

During the past decades, FRP strengthened RC structures have attracted worldwide interest in both application and research. Nowadays, as more and more infrastructures are being suffered from severe corrosions due to harsh and extreme environments, the durability of FRP strengthened RC structures has generally emerged as the most important issue in research. Thus, the paper presents the latest p...
