articular cartilage, the load-bearing tissue of the joint, has limited repair and regeneration ability. the scarcity of treatment modalities for large chondral defects has motivated researchers to engineer cartilage tissue constructs that can meet the functional demands of this tissue in vivo. cartilage tissue engineering requires 3 components: cells, scaffold, and environment. owning to their ...

this study compares the functional capabilities of different metacarpal fixation constructs under physiological loadings in an attempt to identify the optimal construct rather than the strongest one. one hundred and twenty-six preserved human metacarpals were mechanically tested after oblique osteotomies and internal fixation. maximum load to failure, average structural rigidity, and energy abs...

using the computational methods, the interaction effect of tyrosine amino acid on graphene wasinvestigated. for this purpose, the density functional theory (dft) in the ground state of 6-31gwas used, and the interaction effects of tyrosine on graphene was investigated through attachmentto three different base positions. different parameters such as energy levels, the amount ofchemical shift in ...

One significant way in which the duplication issue has remained important emerged from the introduction of another factor. By the time of St. Mâlo and the first U.S. formal response to it, the NATO Alliance was also “seized of” concerns about its own military resources and capacities. Having successfully completed the design phase of adapting the NATO Alliance to meet the challenges of the post...

conclusions the findings showed that personal, interpersonal, and functional skills can facilitate nurses’ career advancement. the effects of these skills on career advancement depend on a variety of conditions that require further studies. results the three themes extracted from the data included interpersonal capabilities, competency for career success, and personal capacities. the results sh...
