The amount of phospholipids is calculated from the content of phosphorus and contains 55 mg of phosphatidylcholine of which 30 mg is dipalmitoylphosphatidylcholine. It is suspended in 0.9% sodium chloride solution.The pH is adjusted with sodium bicarbonate to a pH of 6.2 (5.5 to 6.5).UROSURF is an extract of natural porcine lung surfactant consisting of 99% polar lipids (mainly phospholipids) and 1% hydrophobic low molecular weight proteins (surfactant associated proteins SP-B and SP-C).
1.404 Class deviations. Class deviations affect more than one contract action. When an agency knows that it will require a class deviation on a permanent basis, it should propose a FAR revision, if appropriate. Civilian agencies, other than NASA, must furnish a copy of each approved class deviation to the FAR Secretariat. (a) For civilian agencies except NASA, class deviations may be authorized by agency heads or their designees, unless 1.405 (e) is applicable. Delegation of this authority shall not be made below the head of a contracting activity.
President Dwight D. Eisenhower established NASA in 1958 with a distinctly civilian (rather than military) orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act was passed on July 29, 1958, disestablishing NASA's predecessor, the National Advisory Committee for Aeronautics (NACA). The new agency became operational on October 1, 1958.
