An innovative beam concept made from hollow FRP tube with external flanges and filled crumbed rubber concrete was investigated respect to bending shear. The performance of the rubberised-concrete-filled specimens then compared normal-concrete-filled tubes. A comparison between flanged non-flanged concrete-filled tubes also implemented. Moreover, finite element simulation conducted predict funda...

Highly collimated, plasma-filled magnetic-flux tubes are frequently observed on galactic, stellar, and laboratory scales. We propose that a single, universal magnetohydrodynamic pumping process explains why such collimated, plasma-filled magnetic-flux tubes are ubiquitous. Experimental evidence from carefully diagnosed laboratory simulations of astrophysical jets confirms this assertion and is ...

OBJECT The authors' long-term goal is repair of peripheral nerve injuries by using synthetic nerve guidance devices that improve both regeneration and functional outcome relative to an autograft. They report the in vitro processing and in vivo application of synthetic hydrogel tubes that are filled with collagen gel impregnated with growth factors. METHODS Poly(2-hydroxyethyl methacrylate-co-...

BACKGROUND Anecdotal observations by pharmacists monitoring anticoagulated patients indicate that blood samples collected in 2.7-mL (pediatric) evacuated tubes frequently produced falsely elevated international normalized ratio (INR) results. OBJECTIVE To evaluate the impact of various preanalytical variables (fill volume, sample mixing, and elapsed time between sample collection and mixing) ...

With significant advances in the research and application of nerve conduits, they have been used to repair peripheral nerve injury for several decades. Nerve conduits range from biological tubes to synthetic tubes, and from nondegradable tubes to biodegradable tubes. Researchers have explored hollow tubes, tubes filled with scaffolds containing neurotrophic factors, and those seeded with Schwan...

-The characteristics of a number of metal components proposed as impact energy absorbers are reviewed, attention being focussed on to modes of deformation which stem from the axial compression of metal tubes. Progressive buckling, inversion and splitting are discussed and areas for future work identified. The buckling of thin-walled square section tubes filled with polyurethane foam is also des...

This paper examines the behaviour of circular steel tubes infilled with concrete incorporating recycled rubber particles. The rubberised concrete-filled are tested under lateral cyclic deformations and without co-existing axial loading. A detailed account tests on twelve specimens is provided together complementary material section tests. replacement ratio varied up to a relatively high value 6...
