Abstract: The performance of corroded reinforced concrete (RC) beams strengthened with externally bonded carbon fiber reinforced polymer (CFRP) materials may be affected by a weak interface caused either by defective bonding between the new and old concrete in the case of cover replacement or by expansive cracks in the case of direct application. To investigate this effect, thirteen strengthene...

Fluidic self-assembly is a promising pathway for parallel fabrication of devices made up of many small components. Here, we introduce 'railed microfluidics' as an agile method to guide and assemble microstructures inside fluidic channels. The guided movement of microstructures in microfluidic channels was achieved by fabricating grooves ('rails') on the top surface of the channels and also crea...

Traumatized anterior teeth require quick functional and esthetic repair. Tooth fragment reattachment is a simple and conservative clinical procedure to restore fractured anterior teeth. Different techniques of reattachment include enamel beveling, "v-" shaped internal enamel and dentin grooves, external chamfer, over contouring, and by placing fiber post, all of which were invasive methods. Thi...

Epoxy bonded steel plates (externally bonded reinforcemen: EBR) for the strengthening of concrete structures were introduced to the construction industry in the late 1960s, and the use of fibre reinforced polymers (FRPs) was introduced in the 1990s, which means that these techniques have already been used in construction for 50 and 25 years, respectively. In the first part of the paper, a histo...

arteries internally, so much so that the margins of the grooves appear like two swelling waves above the level of the internal surface of skull-cap. The meningeal grooves are deep. The skull-cap is also unsymmetrical, its chief buik running backward, and to the right. A piece of bone, a lamina I5 inch long and i inch broad, has formed in connection with the anterior part of the falx cerebri at ...

A direct bonded fixed partial dental prosthesis, with a composite resin denture tooth as a pontic, a tri-n-butylborane initiated adhesive resin, and screw posts for reinforcement, was still functioning after an observation period of 20 years. The prosthesis was found to be reliable for long-term clinical use when chemically and mechanically reinforced.

Bondstress-slip models of externally bonded FRP plates have long been quantified using push/pull shear tests in which the joint is slightly greater than effective length plate. This inhibits formation a frictional component that may arise joints. Moreover, previous researchers used several factors to represent bondstress-slip model parameters gave rise number models. With mind, first aim this s...
