Passive and Active Lighting Protection [PDF]
, 2021 The article discusses various types of lightning protection, from a Franklin lightning rod to a heavy-duty laser lightning protection device. Description of passive (protects only one object) and active (protects several objects at once) lightning protection systems.

On the Applicability of Spacecraft Passive Protection
Journal of Surface InvestigationThe spacecraft passive protection of a monolithic and a screen types has been considered. The screen passive protection includes one additional protective shield placed in front of the protected wall. The penetration length of particles for various types of passive protection has been estimated.

Protecting designs with a passive thermal tag
2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008The theft of electronic designs and in particular Intellectual Property (IP) Cores is problematic [1]. Proving a design has been stolen is difficult if not impossible. A method is required to quickly and cheaply identify electronic designs and especially IP Core designs embedded within larger chips or programmed into Field Programmable Gate Arrays ...

AbstractAn “Inhibitor” is something added to a corrosive liquid to render it non‐corrosive; “passivity” is a change in the metal remaining after it has emerged from the “inhibiting” bath, enabling it to resist liquids which normally would corrode it. The object of the paper is to ask whether passivity is due to (1) a three‐dimensional film (2) a two ...

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.

The development of aerospace engineering has given rise to the need to create lightweight high-temperature structures, polymeric and composite materials, fiberglasses and carbon fiber-reinforced polymers that are widely used as thermal protective materials.

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.

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 ...
