In one group, including M 2 UO 4 (M=Li, Na, K) and MUO 4 (M=Ca, Sr) there are six additional oxygen atoms. Taking calcium uranate, CaUO 4 , as an example, the six oxygen atoms are arranged as a flattened octahedron , flattened along the 3-fold symmetry axis of the octahedron which also runs through the O-U-O axis (local point group D 3d at the ...
The psalm could also be interpreted as a "dialogue", as the priests and Levites who served in the Temple are enjoined in verses 1 and 2 to spend their time during the night watch in acts of devotion rather than small talk; and in verse 3 these devotees are urged to pray for the one who enjoined them in verse 1 – either the high priest or a ...

Sodium diuranate, also known as the yellow oxide of uranium, is an inorganic chemical compound with the chemical formula Na 2 U 2 O 7. It is a sodium salt of a diuranate anion. It forms a hexahydrate Na 2 U 2 O 7 ·6H 2 O. Sodium diuranate is commonly referred to by the initials SDU. [1] Along with ammonium diuranate it was a component in early ...
Ammonium diuranate or (ADU) ((NH 4) 2 U 2 O 7), is one of the intermediate chemical forms of uranium produced during yellowcake production. The name "yellowcake" originally given to this bright yellow salt, now applies to mixtures of uranium oxides which are actually hardly ever yellow.
1% and 2% uranyl acetate solutions are used as an indicator, and a titrant in stronger concentrations in analytical chemistry, as it forms an insoluble salt with sodium (the vast majority of sodium salts are water-soluble). Uranyl acetate solutions show evidence of being sensitive to light, especially UV, and will precipitate if exposed.
Opening verse of matins. Nocturns (Latin: nocturni or nocturna) is a Christian canonical hour said in the nighttime.. In the liturgy of the Roman Rite of the Catholic Church, nocturns refer to the sections into which the canonical hour of matins was divided from the fourth or fifth century until after the Second Vatican Council.
Uranyl nitrate is important for nuclear reprocessing.It is the compound of uranium that results from dissolving the decladded spent nuclear fuel rods or yellowcake in nitric acid, for further separation and preparation of uranium hexafluoride for isotope separation for preparing of enriched uranium.
