Vitamins D are essential in minute quantities (few IUs per kilogram body weight daily, only a fraction of a milligram), and like most fat soluble vitamins, they are toxic in larger doses, causing hypervitaminosis D. If the poisoning is severe enough (that is, if the dose of the toxin is high enough), it leads to death.
Some Greek measures of length were named after parts of the body, such as the δάκτυλος (daktylos, plural: δάκτυλοι daktyloi) or finger (having the size of a thumb), and the πούς (pous, plural: πόδες podes) or foot (having the size of a shoe).

Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.
[9] [70] [71] The precise thicknesses of the different layers in the interior of Ganymede depend on the assumed composition of silicates (fraction of olivine and pyroxene) and amount of sulfur in the core. [47] [70] [72] [73] Ganymede has the lowest moment of inertia factor, 0.31, [9] among the solid Solar System bodies. This is a consequence ...
Data from the Fermi Space Telescope (2013) [5] have been interpreted as evidence that a significant fraction of primary cosmic rays originate from the supernova explosions of stars. [ 6 ] [ better source needed ] Based on observations of neutrinos and gamma rays from blazar TXS 0506+056 in 2018, active galactic nuclei also appear to produce ...
The density of Tethys (0.985 g/cm 3) is less than that of water, indicating that it is made mainly of water ice with only a small fraction of rock. [43] Dione is the second-largest inner moon of Saturn. It has a higher density than the geologically dead Rhea, the largest inner moon, but lower than that of active Enceladus. [53]
