OBJECTIVES The utility of autologous chondrocytes for cartilage repair strategies in older subjects with osteoarthritis (OA) may be limited by both age-related and disease-associated decline in chondrogenesis. The aim of this work was to assess OA Hoffa's fat pad as an alternative source of autologous chondroprogenitor cells and to compare it with OA chondrocytes derived from different areas of...

The enrichment and isolation of thermophilic bacteria capable of rubber [poly(cis-1,4-isoprene)] degradation revealed eight different strains exhibiting both currently known strategies used by rubber-degrading mesophilic bacteria. Taxonomic characterization of these isolates by 16S rRNA gene sequence analysis demonstrated closest relationships to Actinomadura nitritigenes, Nocardia farcinica, a...

Abstract The human fingertip consists of a fingerprint with many micro-grating structures. main roles the could be divided into two purposes, namely, enhancement frictional force and effective transmittance biosignal. In this study, we present fingerprint-inspired end-effector that has not only admirable but also electric conductivity. is composed fluorocarbon rubber, one famous materials to ac...

The identification of mammary gland stem cells (MGSC) or progenitors is important for the study of normal breast development and tumorigenesis. Based on their immunophenotype, we have isolated a population of mouse mammary gland cells that are capable of forming "mammospheres" in vitro. Importantly, mammospheres are enriched for cells that regenerate an entire mammary gland on implantation into...

The application of thermoplastic polymers as a matrix material in fibre reinforced composites has grown steadily over the last decades [1]. Thermoplastic composites offer clear advantages over their thermoset counterparts in terms of improved fracture toughness, potential for recycling and, most notably, the possibility to reshape the product at higher temperatures [1,2]. The latter allows rapi...

Abstract Forming of tires during production is a challenging process for Lagrangian solid mechanics due to large changes in the geometry and material properties rubber layers. This paper extends Arbitrary Lagrangian–Eulerian (ALE) formulation thermomechanical inelastic models with special consideration rubber. The ALE approach based on tracking spatial meshes used, an operator-split employed wh...

Nano-technology is the study of matter behaviour on atomic and molecular scale (i.e. nano-scale). In particular, carbon black is a nano-material generally used for the reinforcement of rubber compounds. Nevertheless, the exact reason behind its success in this concrete domain remains unknown. Characterisation of rubber nano-aggregates aims to answer this question. The morphology of the nano-agg...

Woven fabric reinforced composite materials are typically applied in plate or shell structures, such as ribs, stiffeners and skins. Products of this type can be manufactured with several processes. A few examples are compression moulding, diaphragm forming, matched metal die forming and Rubber Press Forming (RPF). Shape distortions can occur during manufacturing of composite products. During th...

In order to study the effect of surface roughness on lubrication performance an elastic support water-lubricated tilting pad thrust bearing, a mixed (ML) deterministic model is hereby presented based unified Reynolds equation model. This very incorporates elastic–plastic deformation asperities and polymer matrix pad, as well rubber support. The randomly distributed generated by mathematical sha...
