Avian reoviruses have been implicated in respiratory disease enteric conditions including Cloacal pasting in young chicks, pericarditis, hydropericardium, anaemia with swollen spleen and liver and petechiation of skeletal muscle and viral arthritis. This study was conducted to examine properties of reovirus field 3 strains isolated from affected broiler from several farms. An infectious agent was isolated from leg tendons and intestine of broiler with clinical tenosynovitis. The agent grew well on the chicken embryo kideny cells(CEK). One of them produced cytopathic effects(CPE) of round type and formed intranuclear inclusions, and the other was characterized by CPE of syncytical type and cytoplasmic inclusion. The properties and serological classification of field strains were examined by hemagglutin test, virus neutralization test, agar gel precipitin, electropherotype. They showed no hemagglutination reactions and not well neutralization and to possess common antigens detectable by AGP test. RNA electropherotype presented 10 segment band as the previous report. These data suggest that the field strains and standard strains(1133, 1733) may be the same group.

M125 booster is one of the reliable S&A device(safety and arming device) to determine the arming distance of fuze for gun ammunitions from 90 mm to 8 inch in diameter. And it is also well known that the arming distance of M125 booster is determined by the multiplication value of the gun tube property(traveled distance per turn of projectile) and the S&A device property(number of turns to arm), not by the projectile muzzle velocity. We have tried and succeeded in executing a proper analysis on M125 booster to figure out its characteristic constant of arming distance by considering only the gun tube properties and the S&A device properties. More detailed arming distance will be analyzed in the future by considering dynamic characteristics on all elements in the S&A device with vector analysis.
