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 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.

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.

Protecting Hospital Patients from Passive Smoking
Psychological Reports, 1980Ample evidence exists showing the dangers of tobacco smoking for smokers as well as non-smokers exposed to passive smoking (Aronow, 1978; Aronow, Ferlinz, & Glauser, 1977; Russell, Cole, & Brown, 1973). Despite the hazards of tobacco smoking to smokers and non-smokers, little effort has been directed to controlling smoking in hospital settings.

PASSIVE FIRE PROTECTION FOR ALUMINUM STRUCTURES
Naval Engineers Journal, 1975ABSTRACTThis paper describes a small scale fire endurance test program sponsored by the Naval Sea Systems Command to screen candidate thermal insulation systems for passive fire protection of aluminum structures.An incombustible thermal Insulation system tested in 1–3/4 inch thickness provided the same degree of fire protection as three inches of a ...

Passive radar for airborne platform protection
International Journal of Microwave and Wireless Technologies, 2012The paper presents the idea of the application of passive radar on board of an airplane. The aim of the passive coherent location (PCL) system is to provide surveillance information to the pilot (or autopilot), to detect the targets in the surveillance space, and to protect the platform from collisions and other threats.

Passive radar for strategic object protection
2011 IEEE International Conference on Microwaves, Communications, Antennas and Electronic Systems (COMCAS 2011), 2011This paper presents an overview of recent research and developments in passive radars at Warsaw University of Technology. The main goal is to show potential of passive radars to provide wide area covert surveillance to protect sensitive infrastructure and strategic objects (e.g. embassies, airports, power plants, railway station, etc.).

Passive Protection Versus Active Defenses
Naval Engineers Journal, 2001ABSTRACTThe increased risk of surprise attacks resulting from changed Navy missions (Hansen 2000; Hansen and Wagner 2001) makes it desirable to consider the possible development of improved passive protection systems. It is not obvious, however, which direction such development should take for optimum returns.

Passivity and Protective Oxide Films
Nature, 1928IN NATURE of Feb. 11 (p. 222) it is stated that “An X-ray examination of finely divided iron, nickel, and chromium, conducted by F. Kruger and E. Nahring at Greifswald, has shown conclusively that films of oxide thicker than 10−7 cm. are not present on the surface of a passive metal.” Lest a wrong impression be gained from this statement, I would ...
