This paper presents an experimental and numerical study on large dimension concrete-filled square low steel ratio tubular (CFST) stub columns under axial loading. Four specimens were designed to investigate the effects of confinement effect CFST with a ratio. ABAQUS was used establish 3D finite element (FE) models for simulation Furthermore, based verification, definition index ( ϕ = f s A /( c...

Objective(S): In this work, paclitaxel (PX), a promising anticancer drug, was loaded in the basil seed mucilage (BSM) aerogels by implementation of supercritical carbon dioxide (SC-CO2) technology. Then, the effects of operating conditions were studied on the PX mean particle size (MPS), particle size distribution (PSD) and drug loading efficiency (DLE). <stron...

Albro, M B; Li, R; Yeager, K ; Hung, C L; Ateshian, G A Columbia University, New York, NY [email protected] INTRODUCTION: Transport pathways play a key role in maintaining cellular metabolic activity. Efforts to maintain or enhance the transport of nutrients may prove beneficial to native and engineered tissue, particularly in avascular tissues such as articular cartilage. Various studies h...

The intervertebral disk has an excellent swelling capacity to absorb water, which is thought to be largely due to the high proteoglycan composition. Injury, aging, degeneration, and diurnal loading are all noted by a significant decrease in water content and tissue hydration. The objective of this study was to evaluate the effect of hydration, through osmotic loading, on tissue swelling and com...

Earlier results [1,2]2 on safe loads for a Prandtl-Reuss material subject to surface tractions or displacements which increase in ratio are here extended to any perfectly plastic material and any history of loading.

The main aim of this study was to prepare apple pomace polyphenolic extract (APPE- referred to as a core) loaded into biodegradable and commercially available natural polymer such as maltodextrin (MD-referred to as a shell). The polymer coating potentially improves its low stability and bioavailability and also directs the control release of the encapsulated material. The MD-nanoparticles (NPs)...
