Fatigue of cortical bone produces microcracks; it has been hypothesized that these cracks are analogous to those occurring in engineered composite materials and constitute a similar mechanism for fatigue resistance.
Fortunately, cell transplantation strategies can provide a viable treatment option to overcome the limitations of autograft harvesting and the reduced colonization of nonautograft materials and constitute one of the most promising instruments to enhance reconstruction of both hard and soft tissues [ 43, 44].
Xylan is a major component of hemicellulose, which is the second most abundant plant material in nature and constitutes up to 35% of the total dry weight of higher plants [ 4].
We sequenced all PCR amplicons of the sampled taxa and obtained 32 RE presence/absence patterns that span crocodilian phylogeny (fig. 1 and supplementary table S1, Supplementary Material online) and constitute the hitherto first RE presence/absence analysis in this amniote taxon.
The rest of the choreographic material, and this constitutes most of the show, is a less appealing strand of dance-theater, in which the cast speaks (sometimes just mouthing words) while making a multitude of gestures that become more finicky with each passing moment.
"Creep" is the term used to describe the time-dependent deformation or strain that a material undergoes under load and constitutes its viscoelastic response to an externally applied stress.
Organic photovoltaics (OPVs) are particularly promising alternatives for solar-cell generation of energy because of the abundance of their constituent elements and base materials, their low cost, and relative ease of chemical synthesis; moreover, massive fabrication of related materials has been applied and constitutes an established and robust technology.
This second option is, in fact, the role played by calcium phosphate and constitutes materials that show the closet similarity to the mineral component of bone [ 14].
They will urge him to announce that the declaration is false and constitutes a "material breach" -- and then send the bombers.
It is a reflection of the regime's well-earned reputation for dishonesty and constitutes a material breach of United Nations Security Council Resolution 1441, which set up the current inspections program.
