  2. Protactinium - Wikipedia

    en.wikipedia.org/wiki/Protactinium

    The polytrioxophosphate Pa(PO 3) 4 can be produced by reacting the difluoride sulfate PaF 2 SO 4 with phosphoric acid (H 3 PO 4) under an inert atmosphere. Heating the product to about 900 °C eliminates the reaction by-products, which include hydrofluoric acid, sulfur trioxide, and phosphoric anhydride.

    en.wikipedia.org/wiki/Physician_assistant

    Physician assistant (or associate) education is shorter than a medical degree required to become a physician. It also typically does not involve residency training, although this is increasingly offered in a variety of specialties. Renewal of certification is usually required every few years, varying by jurisdiction. [citation needed]

  6. Degree of reaction - Wikipedia

    en.wikipedia.org/wiki/Degree_of_Reaction

    The degree of reaction contributes to the stage efficiency and thus used as a design parameter. Stages having 50% degree of reaction are used where the pressure drop is equally shared by the stator and the rotor for a turbine. Figure 4.
