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...

This study was carried out to evaluate the utilization probability of the fibrous root part (FRP) of Bletilla striata, which was usually discarded and harvesting pseudobulb part (PSP). The chemical composition, total phenolic content, DPPH radical scavenging activity, Ferric-reducing antioxidant power and tyrosinase inhibition activity were compared between FRP and PSP. Antioxidant and pro-oxid...

Fiber-reinforced polymer (FRP) reinforcing bars have aTtracted considerable 0llellli0l1 for applications where corrosion of steel reinforcement is problemaric. Due 10 rhe generally low elastic modulus and poor bond clwracreristics of FRP as coil/pared 10 steel reinforcing bars, the use of FRP results in IGI:i?er crack widlhs under senJice loads. Fiber-reinforced concrete (FRe) is proposed for u...

In an attempt to identify autoantigens of synovium in rheumatoid arthritis (RA), we constructed lambda phage expression cDNA libraries from synovium and screened them by IgG purified from synovial fluids, both of which were derived from RA patients. As a result of this unique combination of the libraries and probes, we cloned follistatin-related protein (FRP) as a novel autoantigen in systemic ...

The overall objective of this research project was to conduct an extensive study of the behavior and use of glass fiber-reinforced polymer (GFRP) and carbon FRP (CFRP) materials for bridge construction. In particular, GFRP honeycomb sandwich panels were used as bridge panels and steel-supported bridge deck panels and CFRP and GFRP bars were used as internal reinforcement for precast concrete br...

Functional Reactive Programming (FRP) is a declarative programming model for constructing interactive applications based on a continuous model of time. FRP programs are described in terms of behaviors (continuous, timevarying, reactive values), and events (conditions that occur at discrete points in time). This paper presents Frappé, an implementation of FRP in the Java progamming language. The...

Over the last two decades fiber-reinforced polymer (FRP) rods have emerged as one of the most promising and affordable solutions to the corrosion problems of steel reinforcement in structural concrete. The application of FRP rods in new or damaged structures requires the development of design equations that must take into account the mechanical properties and the durability properties of FRP pr...

This report deals with the experimental investigation of using large deformable FRP, ± 45° oriented fibers, in concrete-filled fiber tubes (CFFT) under axial cyclic compressive loading. In addition, this report presents finite element modeling (FE) of CFFTs with large rupture strain FRP (LRS-FRP). The LRS-FRP is made with polyethylene naphthalate (PEN) and polyethylene terephthalate (PET) fiber...

در این تحقیق  کیفیت اپتیکی و  عملکرد لیزری میله های لیزری Ce,Nd:YAG مورد مطالعه تجربی قرار گرفته است. برای این منظور دو بلور Ce,Nd:YAG رشد داده شده و از آنها میله های لیزری ساخته شده و مقایسه نسبتا جامعی از خواص اپتیکی و لیزری دو میله لیزری آنیل شده در هوا و ازت و نیز میله لیزر Nd:YAG  انجام شده است. و نتایج حاکی از کیفیت اپتیکی و عملکرد لیزری مناسب تر  میله لیزر Ce,Nd:YAG  آنیل شده در ازت دارد.
