Parrotfish Teeth: Stiff Biominerals Whose Microstructure Makes Them Tough and Abrasion-Resistant To Bite Stony Corals
Published 2017“…To investigate how their teeth endure the associated contact stresses, we examine the chemical composition, nano- and microscale structure, and the mechanical properties of the steephead parrotfish <i>Chlorurus microrhinos</i> tooth. Its enameloid is a fluorapatite (Ca<sub>5</sub>(PO<sub>4</sub>)<sub>3</sub>F) biomineral with outstanding mechanical characteristics: the mean elastic modulus is 124 GPa, and the mean hardness near the biting surface is 7.3 GPa, making this one of the stiffest and hardest biominerals measured; the mean indentation yield strength is above 6 GPa, and the mean fracture toughness is ∼2.5 MPa·m<sup>1/2</sup>, relatively high for a highly mineralized material. …”

Day of the week effect.
Published 2021“…<u>Explanatory example</u>: For winter hospital admissions, the sd is 3143.5, and the Saturday effect for Bavaria is -0.884. This indicates a decrease in daily hospital admissions by 0.884*3143.5 = 2779 on Saturdays compared to Fridays.…”
