Recent research has focused on rehabilhation and strengthening of steel structures and bridges using fiber reinforced polymer (FRP) materials. The bond behavior of FRP materials to steel structures is quite different from lhat of concrete structures. Preliminary test results showed the occurrence of very high bond stresses for most strengthening applications due to the amount of strengthening r...

Objective To evaluate the ability of the eluate from fibrin-rich plasma (FRP) membrane to induce proliferation and differentiation of isolated human adipose-derived stem cells (ASCs) into chondrocytes. Method FRP membranes were obtained by centrifugation of peripheral blood from two healthy donors, cut, and maintained in culture plate wells for 48 h to prepare the fibrin eluate. The SCATh wer...

It is believed that the reduced FMN substrate required by luciferase from luminous bacteria is provided in vivo by NAD(P)H-FMN oxidoreductases (flavin reductases). Our earlier kinetic study indicates a direct flavin cofactor transfer from Vibrio harveyi NADPH-preferring flavin reductase P (FRP(H)) to the luciferase (L(H)) from the same bacterium in the in vitro coupled luminescence reaction. Ki...

A new layered 4-node, 24-degrees of freedom rectangular composite plate element is developed in this paper for nonlinear finite element analyses of FRP-strengthened RC slabs. The layered approach is used to form an integrated plate element for modelling of concrete, FRP, adhesive layer and steel reinforcement with a perfect bond assumption between each layer. Timoshenko’s composite beam functio...

The performance of the interface between fiber reinforced polymer (FRP) composites and concrete is one of the key factors affecting the behavior of strengthened reinforced concrete (RC) structures. Existing laboratory research has shown that RC beams strengthened with FRP sheets usually fail because of either debonding of the impregnated fabric from the concrete substrate or fracture of the FRP...

Throughout the last 25 years, computational chemistry based on quantum mechanics has been applied to the investigation of reaction kinetics in free radical polymerization (FRP) with growing interest. Nowadays, quantum chemistry (QC) can be considered a powerful and cost-effective tool for the kinetic characterization of many individual reactions in FRP, especially those that cannot yet be fully...

Four putative open reading frames (ORFs) were previously identified in the regions flanking the Streptococcus mutans GS-5 fructosyltransferase (FTF) gene. One of these, ORF 3, appeared to code for a low-molecular-mass protein containing amino acid sequences sharing homology with several Gram-positive bacterial DNA-binding proteins and it was suggested that the ORF 3 gene product might be an FTF...

Functional Reactive Programming (FRP) is an approach to reactive programming where systems are structured as networks of functions operating on signals (time-varying values). FRP is based on the synchronous data-flow paradigm and supports both (an approximation to) continuous-time and discrete-time signals (hybrid systems). What sets FRP apart from most other languages for similar applications ...

The use of fiber reinforced polymers (FRP) for reinforcement of aging and deteriorating concrete members has emerged as a viable and cost effective alternative to traditional repair and strengthening techniques to upgrade deficient structures to meet today’s design standards (Crasto et al., 1996; Myers et al., 2000). The load carrying ability of structures such as beams and columns can be enhan...

The construction sector is well known for its critical environmental impact resulting from the consumed amounts of raw materials and tremendous emissions greenhouse gases. Therefore, scientists need to promote study implications using alternative solutions such as fiber-reinforced polymers (FRP) throughout their service life. FRPs have gained increasing popularity in last few years due durabili...
