S&P Australian Dollar Futures 2x Inverse Daily Index TR (CME:SPADFT2I) Sidelines Mode (-55) - SPADFT2I is moving in a sideways pattern and is unable to gain momentum in either direction. Beware of choppy movement and consider a sidelines position until a stronger trend is identified. ...
Density functional theory has been applied to study the origin of the inverse and normal trans influence in alkylcobalamins. In order to cover the X-ray structural data available for alkylcobalamins with a variety of axial substituents, geometries of 28 related corrin-containing models have been ...
