Proceedings of the IEE - Part B: Radio and Electronic Engineering, 1958
A passive protection cell consists essentially of a t.r. cell containing argon without water vapour. The effects of the omission of water vapour from the gas filling on keep-alive characteristics, leakage power and recovery time are described. Tests on several cells in active duplexing systems have shown that lives in excess of 10000 hours are obtained.

Passive protection of calves with Pasteurella haemolytica antiserum
American Journal of Veterinary Research, 1995SUMMARY Four colostrum-deprived calves each were immunized passively with antisera to whole Pasteurella haemolytica, leukotoxin-containing supernatants of P haemolytica, P haemolytica lipopolysaccharide, or newborn calf serum. Calves were challenge exposed intrabronchially with 5 × 109 P haemolytica, and 24 hours later, the resulting lesions were ...

Passive protection of sheep against capripoxvirus
Research in Veterinary Science, 1986The close antigenic relationship between strains of capripox was shown by passively immunising sheep with serum against capripoxviruses isolated from a sheep and from a goat. Sheep immunised with immune serum to Oman sheep pox or Yemen goat pox resisted challenge with Yemen goat pox or Nigeria sheep pox respectively.

Rotavirus infection in lambs: Studies on passive protection
Archives of Virology, 1976Gnotobiotic lambs were protected against rotavirus infection by the presence in the gut at the time of infection of colostrum or serum containing antibodies to rotavirus. This protection was observed even when passively-acquired antibody was not present in the serum of the infected lamb.

Passive Fire Protection Success
Aircraft Engineering and Aerospace Technology, 1991TESTS recently conducted by the Fire Research Station on behalf of the CAA to assess the effectiveness of onboard water sprinklers involved the construction of a test rig based on the fuselage of a Boeing 707 passenger aircraft. Major fire conditions were created outside and the flames were also drawn into the fuselage in a series of tests.

Performance Assessment of Passive Fire Protection Materials
Industrial & Engineering Chemistry Research, 2011The performance of fireproofing materials in providing effective protection from fire strongly depends on the thermophysical properties and on the behavior of the material during fire exposure. Not only active insulators but also nonactive coatings may undergo significant changes in their structure and properties when exposed to high temperatures.

Passive Immune Protection of Turkeys against Coryza
Avian Diseases, 1997Antisera made against whole cells of Bordetella avium protected turkeys against disease signs of turkey coryza, but antiserum against the dermonecrotic heat-labile toxin (DHLT) did not. Neither antiserum against whole cells nor antiserum against DHLT protected turkeys against colonization of the trachea by B. avium.
