In December 1901 and January 1902, at the direction of archaeologist Jacques de Morgan, Father Jean-Vincent Scheil, OP found a 2.25 meter (or 88.5 inch) tall basalt or diorite stele in three pieces inscribed with 4,130 lines of cuneiform law dictated by Hammurabi (c. 1792–1750 BC) of the First Babylonian Empire in the city of Shush, Iran.
Life insurance (or life assurance, especially in the Commonwealth of Nations) is a contract between an insurance policy holder and an insurer or assurer, where the insurer promises to pay a designated beneficiary a sum of money upon the death of an insured person.
The biological half-life of strontium in humans has variously been reported as from 14 to 600 days, [86] [87] 1,000 days, [88] 18 years, [89] 30 years [90] and, at an upper limit, 49 years. [91] The wide-ranging published biological half-life figures are explained by strontium's complex metabolism within the body.
Martin Heinrich Klaproth (1 December 1743 – 1 January 1817) was a German chemist. [1] He trained and worked for much of his life as an apothecary, moving in later life to the university.
Some authors credit Cruickshank with first suspecting an unknown substance in a Scottish mineral, strontianite, found near Strontian, in Argyleshire.Other authors name Adair Crawford for the discovery of this new earth, due to the mineral's property of imparting a redding color to a flame. [10]
Naturally occurring strontium is nonradioactive and nontoxic at levels normally found in the environment, but 90 Sr is a radiation hazard. [4] 90 Sr undergoes β − decay with a half-life of 28.79 years and a decay energy of 0.546 MeV distributed to an electron, an antineutrino, and the yttrium isotope 90 Y, which in turn undergoes β − decay with a half-life of 64 hours and a decay energy ...
Strontium belongs to the same periodic family as calcium (alkaline earth metals), and is metabolised in a similar fashion, preferentially targeting metabolically active regions of the bone. 89 Sr is an artificial radioisotope used in the treatment of osseous (bony) metastases of bone cancer .
Protective Life Insurance Company was founded in 1907 and paid its first death claim in 1909. In 1927, Protective merged with Alabama National Insurance Company, and Alabama National's president, Samuel Clabaugh, became the president of the combined companies which continued to do business as Protective.
