Rhodium has numerous meta states, the most stable being 102m Rh (0.141 MeV) with a half-life of about 2.9 years and 101m Rh (0.157 MeV) with a half-life of 4.34 days (see isotopes of rhodium). [ 31 ] In isotopes weighing less than 103 (the stable isotope), the primary decay mode is electron capture and the primary decay product is ruthenium .
The incidence of Rh disease is mathematically related to the frequency of D negative individuals in a population, so Rh disease is rare in old-stock populations of Africa and the eastern half of Asia, and the Indigenous peoples of Oceania and the Americas, but more common in other genetic groups, most especially Western Europeans, but also ...
Ethnic distribution of ABO (without Rh) blood types [75] (This table has more entries than the table above but does not distinguish between Rh types.) People group O (%) A (%) B (%) AB (%) Australian Aboriginals: 61: 39 0 0 Abyssinians: 43 27 25 5 Ainu 17 32 32 18 Albanians: 38 43 13 6 Great Andamanese: 9 60: 20 12 Arabs: 34 31 29 6 Armenians ...
A complete blood type would describe each of the 45 blood groups, and an individual's blood type is one of many possible combinations of blood-group antigens. [3] Almost always, an individual has the same blood group for life, but very rarely an individual's blood type changes through addition or suppression of an antigen in infection, malignancy, or autoimmune disease.
The term human blood group systems is defined by the International Society of Blood Transfusion (ISBT) as systems in the human species where cell-surface antigens—in particular, those on blood cells—are "controlled at a single gene locus or by two or more very closely linked homologous genes with little or no observable recombination between them", [1] and include the common ABO and Rh ...
In February 2007, the world's rarest baseball card sold at auction for $2.3 million. If you think that's totally wild, consider the world's rarest bible, which could net you $25 to $35 million.
The U.S. has eight public toilets per 100,000 people. Public toilets were a fact of life in the U.S. and elsewhere for centuries — at least as far back as the Roman Empire. As leaders began to ...
