We obtained medial and lateral subchondral cancellous bone specimens from ten human post-mortem proximal tibiae with early osteoarthritis (OA) and ten normal age- and gender-matched proximal tibiae. The specimens were scanned by micro-CT and the three-dimensional microstructural properties were quantified. Medial OA cancellous bone was significantly thicker and markedly plate-like, but lower in...

The diversity of viruses associated with non-cultivated plants was assessed from plant samples collected in the Tallgrass Prairie Preserve of northeastern Oklahoma, USA. The samples were processed to determine the sequences of nucleic acids extracted from the virus-like particle fraction of plant homogenates. Sequences from 95 specimens of 52 plant species included those of probable origin from...

Wear properties of high-density Ti2AlN oriented specimens prepared by slip casting in a high magnetic field followed SPS were investigated comparing them with nonoriented specimens. The coefficients friction the range 0.25 < μ 0.35 for both and at each load, even without lubrication, low observed. specific wear was lower than that specimens, increased increasing load. top surface specimen showe...

This study aims to contribute the scientific knowledge by investigating influence of build direction and post-curing on material part attributes acrylonitrile butadiene styrene (ABS-like) like resins photopolymerization based additive manufacturing (AM). Specimens were manufactured in different directions with parameters that offer highest density. Two groups specimens, one as-built other post-...
