The company's original name stems from the concept that "making a wiki is as easy as making a peanut butter sandwich". [7] The original beta test of PBworks was released for public comment on May 31, 2005. [8] The site was formally launched in June 2005.
Naval Aircraft Factory version of the PBY-5 with major modification including a 2 ft (0.61 m) bow extension, modified hull lines and step, re-designed tip floats and tail surfaces and a revised electrical system. 155 were built for delivery to the RAF as the Catalina V although 138 were Lend-Leased to the Soviet Navy as the KM-1
As a simplified example, if a beamline runs for 8 hours (28 800 seconds) at an instantaneous luminosity of 300 × 10 30 cm −2 ⋅s −1 = 300 μb −1 ⋅s −1, then it will gather data totaling an integrated luminosity of 8 640 000 μb −1 = 8.64 pb −1 = 0.008 64 fb −1 during this period. If this is multiplied by the cross-section ...
The Consolidated P-30 (PB-2) was a 1930s United States two-seat fighter aircraft. An attack version called the A-11 was also built, along with 2 Y1P-25 prototypes and YP-27 , Y1P-28 , and XP-33 proposals.
Lead azide in its pure form was first prepared by Theodor Curtius in 1891. Due to sensitivity and stability concerns, the dextrinated form of lead azide (MIL-L-3055) was developed in the 1920s and 1930s with large scale production by DuPont Co beginning in 1932. [10]

Plumbide [Pb 5] 2−. Plumbide is an anion of lead atoms. There are three plumbide anions, written as Pb −, Pb 2− and Pb 4− with 3 oxidation states, -1, -2 and -4, respectively. A plumbide can refer to one of two things: an intermetallic compound that contains lead, or a Zintl phase compound with lead as the anion.
