The Chemistry of Americium (Schulz, Wallace W.)

The unveiled states of americium.

Minerals chemistry and geothermobarometry of Dourbeh and Nari intusive bodies of W Urumieyeh, NW Iran

The studied bodies are located in the west of Urumieyeh Lake and northeast of Oshnavieyeh, in the Sanandaj-Sirjan structural zone. Compositionaly, these bodies are formed from gabbro-diorite (Dourbeh) and granite (Nari). Gabbrodiorite rocks are composed of plagioclase (andesine to bytownite), amphibole (calcic group and magnesio-hornblende-tschermakite-hornblende type) and pyroxene (augite) as ...

Hochschild Cohomology of the Liu–schulz Algebras

A description of the Hochschild cohomology algebra for the symmetric 8-dimensional algebras found by Liu and Schulz is given in terms of generators and relations. The dimensions of the cohomology groups are calculated. §

The metabolism of americium in the rat.

The announcement of the discovery of element 95 was made in 1946 by Seaborg and his associates (1). Like neptunium (element 93), plutonium (element 94), and curium (element 96) this new element, americium, is radioactive and has not been observed in nature in appreciable amounts. During the war an extensive study was made of the metabolic properties of plutonium (2) and several other heavy elem...

Wallace on the evolutionary trail

stock exchange; he argued against globalised free trade; an anti-imperialist, he preached “the rights of every people to govern themselves” [12]. The contrast with Darwin is striking. After publication of The Origin, Darwin’s strategy was to consolidate and concretise the arguments laid out in his seminal work. His output remained resolutely scientific. One of the many reasons that Wallace has ...
