[2] While ROE is used in both domestic and international operations by some militaries, ROE is not used for domestic operations in the United States. Instead, the use of force by the U.S. military in such situations is governed by Rules for the Use of Force (RUF). An abbreviated description of the rules of engagement may be issued to all personnel.

Ruthenium hexafluoride was discovered by American radiochemists in 1961, soon after the discovery of technetium hexafluoride. [3] It is made by a direct reaction of ruthenium metal in a gas stream of fluorine and argon at 400–450 °C. The yields of this reaction are less than 10%. [4] Ru + 3 F 2 → RuF 6
Ruthenium pentafluoride is the inorganic compound with the empirical formula RuF 5.This green volatile solid has rarely been studied but is of interest as a binary fluoride of ruthenium, i.e. a compound containing only Ru and F.
RuF 4 in the solid state is polymeric, with a three-dimensional structure of corrugated layers containing RuF 6 octahedra joined by shared fluorine atoms. The crystalline structure is similar to that of vanadium tetrafluoride and is monoclinic , space group P 2 1 / n , with lattice constants a = 560.7 pm, b = 494.6 pm, and c =514.3 pm, β = 121 ...
RuCl 2 (PPh 3) 3 is the product of the reaction of ruthenium trichloride trihydrate with a methanolic solution of triphenylphosphine. [1] [2] 2 RuCl 3 (H 2 O) 3 + 7 PPh 3 → 2 RuCl 2 (PPh 3) 3 + 2 HCl + 5 H 2 O + OPPh 3. The coordination sphere of RuCl 2 (PPh 3) 3 can be viewed as either five-coordinate or octahedral.
Vickers hardness H V = 50 GPa was reported for thin films composed of RuB 2 and Ru 2 B 3 phases. [1] This value is significantly higher than those of bulk RuB 2 or Ru 2 B 3 , but it has to be confirmed independently, as measurements on superhard materials are intrinsically difficult.
Floyd's joke and the ensuing silence. On December 13, 1971, during oral arguments before the United States Supreme Court in the abortion rights case Roe v. Wade, Texas assistant attorney general Jay Floyd prefaced his remarks with a reference to his opposing counsel, Sarah Weddington and Linda Coffee: "It's an old joke, but when a man argues against two beautiful ladies like this, they are ...
