Effects of Material Properties of Warhead Casing on Natural Fragmentation Performance of High Explosive (HE) Warhead

This research paper presents numerical studies of the characteristics of warhead fragmentation in terms of initial velocities, spray angles of fragments and fragment mass distribution of high explosive (HE) warhead. The behavior of warhead fragmentation depends on shape and size of warhead, thickness of casing, type of explosive, number and position of detonator, and etc. This paper focuses on ...

The colibactin warhead crosslinks DNA

Members of the human microbiota are increasingly being correlated to human health and disease states, but the majority of the underlying microbial metabolites that regulate host-microbe interactions remain largely unexplored. Select strains of Escherichia coli present in the human colon have been linked to the initiation of inflammation-induced colorectal cancer through an unknown small-molecul...

Measurements of Radiation from a Soviet Warhead

On 5 July 1989, in a remarkable display of military glasnost, a team of us scientists organized by the National Resources Defense Council (NRDC) and a team of Soviet scientists from the I. v: Kurchatov Institute of Atomic Energy measured the radiation emitted by the nuclear warhead of a cruise missile aboard the Soviet ship Slavs. The measurements took place in the Black Sea off Yalta. We publi...

Designing Protocols for Nuclear Warhead Verification

Future arms-control and disarmament treaties could place numerical limits on all categories of nuclear weapons in the arsenals of weapon states, including tactical weapons, non-deployed weapons, and weapons awaiting dismantlement. Verification of such agreements is likely to require new types of inspection equipment — but also new verification protocols. This paper offers a set of definitions a...
