Ground hardness and injury in community level Australian football.
Twomey DM, Finch CF, Lloyd DG, Elliott BC, Doyle TL. Twomey DM, et al. J Sci Med Sport. 2012 Jul;15(4):305-10. doi: 10.1016/j.jsams.2011.12.003. Epub 2012 Jan 17. J Sci Med Sport. 2012. PMID: 22257965
RESULTS: Clegg hammer readings ranged from 25 to 301 g. Clegg hammer hardness categories from low/normal to high/normal were associated with the majority of injuries, with only 3.7% (13 injuries) on unacceptably high hardness and 0.3% (1 injury) on the unacceptably …

Enhancement of the Gel Hardness of Candelilla Wax through the Addition of Long-chain Ester Wax Behenyl Behenate.
Shimizu T, Tanabe T, Kachi H, Shibata M. Shimizu T, et al. J Oleo Sci. 2022;71(12):1725-1733. doi: 10.5650/jos.ess22175. J Oleo Sci. 2022. PMID: 36464285 Free article.
In this study, behenyl behenate (BB), an additive plant-derived wax ester with a high melting point, was shown to improve the oil-gel hardness of CW.Although the gel with BB alone had a relatively low gel hardness, when BB was mixed with CW at a ratio of 70:3 …

On the relationship between indentation hardness and modulus, and the damage resistance of biological materials.
Labonte D, Lenz AK, Oyen ML. Labonte D, et al. Acta Biomater. 2017 Jul 15;57:373-383. doi: 10.1016/j.actbio.2017.05.034. Epub 2017 May 22. Acta Biomater. 2017. PMID: 28546134
Across seven orders of magnitude, indentation hardness was directly proportional to indentation modulus. Using a lumped parameter model to deconvolute indentation hardness into components arising from reversible and irreversible deformation, we establish criteria wh …

Analysis of the Hardness of Soft Relining Materials for Removable Dentures.
Białożyt-Bujak E, Wyszyńska M, Chladek G, Czelakowska A, Gala A, Orczykowska M, Białożyt A, Kasperski J, Skucha-Nowak M. Białożyt-Bujak E, et al. Int J Environ Res Public Health. 2021 Sep 8;18(18):9491. doi: 10.3390/ijerph18189491. Int J Environ Res Public Health. 2021. PMID: 34574415 Free PMC article.
The exception was GC Reline Soft, for which a marked increase in hardness was noted. All materials based on acrylates were characterized by successive increase in hardness over time. However, in the case of the Vertex Soft material, the increase in hardness w …

Alternative mechanisms of increased eggshell hardness of avian brood parasites relative to host species.
Igic B, Braganza K, Hyland MM, Silyn-Roberts H, Cassey P, Grim T, Rutila J, Moskát C, Hauber ME. Igic B, et al. J R Soc Interface. 2011 Nov 7;8(64):1654-64. doi: 10.1098/rsif.2011.0207. Epub 2011 May 11. J R Soc Interface. 2011. PMID: 21561966 Free PMC article.
Obligate brood parasitic birds lay their eggs in nests of other species and parasite eggs typically have evolved greater structural strength relative to host eggs. Increased mechanical strength of the parasite eggshell is an adaptation that can interfere with puncture ejec …
