A flexible non-enzymatic electrochemical sensor based on a braided copper cobaltite/MWCNT composite capable of detecting acetylcholine at sub-nanomolar level was developed to monitor released by human neural cells.

The management of sternoclavicular injuries in skeletally immature patients has not been well described. The purpose of this study was to describe the authors' experience treating this rare and potentially life-threatening injury. All skeletally immature patients who underwent treatment for a medial clavicular physeal fracture or sternoclavicular dislocation between 2003 and 2011 were identifie...

Little is known about the effect of specimen preparation and testing protocols on the micro-shear bond strength (μSBS) results. To evaluate whether variations in polyethylene rod use affect (μSBS)). Human dentin disks were randomly distributed into six groups (n = 5): polyethylene tube (3 levels) and adhesive system (2 levels). In Group 1, polyethylene tubes filled with polymerized composite) w...

Braided composites are a class of composite materials that feature an inter-woven structure improves structural stability and damage tolerance. Presently, braided under tension torsion loading have been studied individually. Mechanical behaviour combined tension–torsion is common therefore requires investigation. In this study, mechanical properties carbon fibre, fibreglass aramid 2D tubular (T...

Objectives: To evaluate the micro-tensile repair bond strength between aged and new composite, using silane and adhesives that were cured or left uncured when new composite was placed. Methods: Eighty Filtek Supreme XLT composite blocks and four control blocks were stored in water for two weeks and thermo-cycled. Sandpaper ground, etched and rinsed specimens were divided into two experimental g...

A tubular braided composite bone cast for improving the efficiency and quality of bone fracture treatment is investigated. Finite element analysis was used to evaluate stress concentrations in fracture sites supported with plate and tubular casts. The stress in a plated bone is 768 % of that in a whole bone at the same location, while it is only 47 % in a bone with a tubular cast. Three unbroke...

Braided differential operators ∂ are obtained by differentiating the addition law on the braided covector spaces introduced previously (such as the braided addition law on the quantum plane). These are affiliated to a Yang-Baxter matrix R. The quantum eigenfunctions expR(x|v) of the ∂ i (braided-plane waves) are introduced in the free case where the position components xi are totally noncommuti...

The objective of this paper was to fabricate a biodegradable tubular scaffold for small diameter (d<6 mm) blood vessel tissue engineering. The tube scaffold needed a porous wall for cell attachment, proliferation and tissue regeneration with its degradation. A novel method given in this paper was to coat a porous layer of poly (epsilon-caprolactone) (PCL) on the outside of a poly (glycolic-co-l...
