Abstract: The present disclosure relates generally to certain compounds, pharmaceutical compositions comprising said compounds, and methods of making and using said compounds and pharmaceutical compositions. The compounds and compositions provided herein may be used for the treatment or prevention of a Retroviridae infection, including an HIV infection.

Abstract: Provided is a lubricating oil composition that includes a major amount of a lubricant base oil and a minor amount of a viscosity index improver comprising a syndiotactic propylene-based ethylene-propylene copolymer comprising: a) 2 to 20% by weight of ethylene, b) 80 to 98% by weight of propylene; c) 50 to 99% of rr triads; and d) Mw (LS) of 10 to 250 kg/mol.

Abstract: An x-ray imaging system (10) for generating multiple energy x-ray images is provided. The system (10) includes an exposure switch (32) having an “ON”state. A console (14) is electrically coupled to the exposure switch (32) and contains two or more selected imaging program sets. An x-ray generator (18) generates x-rays. An image detector (28) detects the x-rays and generates two or more electronic signals. An image generation controller (20) is electrically coupled to the image detector (28) and controls the sequencing of the two or more electronic signals. An x-ray controller (12) is electrically coupled to the console (14) and the x-ray generator (18). The x-ray controller signals the image generation controller (20) to generate the two or more electronic signals sequentially when the exposure switch (30) is in the ON state and in response to the two or more selected imaging program sets. A method for performing the same is also provided.
