Treatments on Polypropylene Macro Synthetic Fibers for Improving Adhesion in Structural Concrete Reinforcement: A Systematic Review

Journal of Applied Polymer Science, EarlyView.
Surface functionalization of polypropylene macrofibers to enhance fiber‐matrix interfacial bonding. ABSTRACT Concrete is the most used higher compressive strength‐building material, albeit brittle to tensile, and flexural loads. Polypropylene (PP) synthetic polymeric macrofibres are commonly employed as reinforcement material to prevent this situation ...

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

‘Where are the adults?’: Troubling child‐activism and children's political participation

British Educational Research Journal, EarlyView.
Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...

A total life prediction model for stress concentration sites [PDF]

Fatigue crack growth tests were performed on center crack panels and radial crack hole samples. The data were reduced and correlated with the elastic parameter K taking into account finite width and corner crack corrections.
