Synopsis: The effects of thermal loads on the structural performance of FRP reinforced concrete elements are analyzed in this paper. The difference in transverse coefficient of thermal expansion (CTE) between FRP and concrete causes the presence of tensile stresses within the concrete and, eventually, the formation of cracks when the temperature increases. As part of an inter-university experim...
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...
Two 10 and 20nm samples of Cu nano-cluster were grown on quartz substrates with a thickness of by electron beam deposition method. Nanolayers of titanium dioxide with a thickness of 300 nm were deposited on these Cu nano-cluster layers. For comparison، a layer of titanium dioxide with a thickness of 300 nm was also coated on quartz substrate. All coatings were conducted using electron-beam phys...
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...
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...
Concrete columns confined with high-strength fiber reinforced polymer (FRP) composites can enhance the strength as well as the ductility of such structures. In recent years, the use of FRP composites to repair and strengthen existing reinforced concrete (RC) structures has been widely used. When the columns of existing RC structures are wrapped with FRP composites, the core concrete of such col...
Thin laminates made of high-strength pultruded fiber reinforced polymers (FRP) are increasingly being used to reinforce glue-laminated timber (glulam) beams, creating a new composite glulam (FRP glulam) significantly stronger in bending than a conventional (unreinforced) glulam of equal size. Large timber members have long been recognized for maintaining structural integrity in fires and this p...
The first Fibre Reinforced Polymer (FRP) implemented to a UK Railway Bridge was in 2001, since then a number of key railway bridge projects involving FRP have seen completion; six being fully FRP bridges. Although the potential use of FRP on the infrastructure was found in 1998 due to high strength to weight ratio, stiffness and good chemical resistance, the implementation of FRP to small scale...
CoFe/Cu multilayer nanowires were electrodeposited into anodic aluminum oxide templates prepared by a two-step mild anodization method, using the single-bath technique. Nanowires with 30 nm diameter and the definite lengths were obtained. The effect of CoFe layers thickness and annealing on the magnetic behavior of the multilayer nanowires was investigated. The layers thickness was controlled t...
