ells exposed to repeated stretching along a unidirectional axis reinforce their actin stress fibers and reorient them to run perpendicular to the direction of strain. The two aspects of the response are regulated independently, report Yoshigi et al. (page 209). Numerous tissues are exposed to repeated mechanical strain and respond by C After stretching (bottom), re-localization of zyxin to stre...

Bi-directional WDM transmission is a technique that allows data to be transmitted simultaneously in both directions of a fiber, with different sets of wavelength channels for each direction. Compared with unidirectional WDM systems, it not only saves the cost of deploying extra fibers, but also allows more flexible bandwidth provisioning. To exploit this flexibility, we investigate path protect...

Several types of cells show left–right asymmetric behavior, unidirectional rotation, or spiral movements. For example, neutrophil-like differentiated HL60 (dHL60) leftward bias in response to chemoattractant. Neurons extend neurites, creating a clockwise spiral. Platelet shows arrangements actin fibers. In the microfabricated culture environment, groups C2C12 (mouse myoblast cell line) were aut...

Vascular endothelial cell migration is critical in many physiological processes including wound healing and stent endothelialization. To determine how preexisting cell morphology influences cell migration under fluid shear stress, endothelial cells were preset in an elongated morphology on micropatterned substrates, and unidirectional shear stress was applied either parallel or perpendicular to...

When analyzing the fracture behavior of unidirectional carbon fiber-reinforced polymer (CFRP), it is important to consider interfacial strength between reinforcing fiber and base resin, resin. Therefore, adhesiveness material compatibility with sizing fibers are design parameters in development CFRPs. However, a quantitative method for estimating resin has not been established. In this study, w...

Unidirectional chloride efflux and influx were studied in giant barnacle muscle fibers that were internally dialyzed. When cyclic 3'5'-adenosine monophosphate (cAMP) was included in the dialysis fluid, both unidirectional fluxes were stimulated by about the same amount. This stimulation was not associated with measurable changes either in membrane electrical conductance or with net movements of...

A Model to Predict the Long-Term Strength of E-Glass Fiber Composites Subjected to Environmental Exposure Thomas Miles Damiani Glass Fiber Reinforced Plastics (FRP) are being used in an increasing number of structures and machines because of their advantages over conventional materials such as steel or aluminum. However, sustained exposure to seemingly nominal service conditions can act to degr...

Fiber reinforced polymer (FRP) laminates are being used as external reinforcement for strengthening concrete members. The performance of unidirectional FRP laminates is highly dependent on fiber orientation with respect to applied load direction. In the case of fabrication by manual lay-up, it is possible to have fiber plies installed with improper orientation. In this project, the degradation ...
