11. Shielding makes use of the electrical principle of the Faraday cage.12. Defense against persistent agents requires shielding for extended periods of time. 13. These become pendent in rainy weather thus shielding the reproductive parts. 14. Countermeasures include putting visual shielding over sensitive targets or camouflaging them. 15. Thin shields also have internal reflections that reduce the shielding effectiveness. 16. 1976 models featured steel floor panels shielding the catalytic converter exhaust. 17. It was unarmored apart from some light shielding for the crew. 18. Gable roof with eaves shielding half the peak arcade and shingled. 19. Barnes responded by manipulating the strike and shielding Bradman from Bedser. 20. The fluid cell is designed with shielding to minimize electrical noise.
