The spherical coordinate u is the angle from the z axis, varying from 0 to p, and f is the angle from the x axis, varying from 0 to 2p. Conversion between Cartesian and spherical coordinates is carried out with the following expressions: rdu z = r cos u In spherical coordinates, the three sides of the volume element are r du, r sin u df, and dr.

albite: Topics by Science.gov

 · 2017-10-19. Albite (NaAlSi 3 O 8 ), a framework silicate of the plagioclase feldspar family and a common constituent of felsic rocks, is often present in the siliceous mineral aggregates that compose concrete. When exposed to radiation (e.g., in the form of neutrons) in nuclear power plants, the crystal structure of albite can undergo ...

 · The K-T boundary claystone, which is composed of kaolinite and small amounts of illite/smectite mixed-layer clay, is similar in most respects to kaolinite tonstein layers in coal beds. At some, but not all, K-T boundary localities, the boundary claystone contains solid kaolinite and hollow and solid goyazite spherules, 0.05 to 1.2 mm in diameter.

 · 2011-09-01. The hydrogen and deuterium atom addition reactions of CO to form HCO and DCO are addressed by Harmonic Quantum Transition State Theory calculations. Special attention is paid to the reactions at very low temperatures (5-20 K) where it is found that quantum tunneling leads to substantial rates of reaction.
