Discussions on a long gap discharge to an EHV transmission tower by a rocket triggered lightning experiment [PDF]

open access: yes
The triggered lightning experiments using a rocket have been carried out on a winter mountain in Japan since 1986. For the four years from 1986 to 1989, 39 rockets were launched and 19 of them triggered lightning strikes.

An assessment of tailoring of lightning protection design requirements for a composite wing structure on a metallic aircraft [PDF]

open access: yes
The Navy A-6E aircraft is presently being modified with a new wing which uses graphite/epoxy structures and substructures around a titanium load-bearing structure. The ability of composites to conduct electricity is less than that of aluminum.

Lightning Discharge and Fundamentals of Lightning Protection [PDF]

open access: yesJournal of Lightning Research, 2012
A review of lightning protection concepts introduced by Benjamin Franklin (18th century) and James Clerk Maxwell (19th century) is given. Modern approaches to lightning protection of various structures and systems are discussed. In particular, the widely used electrogeometrical model (one version of which is the Rolling Sphere Method) and the ...

Delivery of nano‐formulated drugs to solid tumours is selectively increased by co‐application of the vascular disrupting agent CA4P

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and purpose Nano‐formulated chemotherapeutics prolong systemic availability of drugs and can reduce systemic toxicity, but their accumulation in solid tumours is often limited and unpredictable. Broadly applicable strategies to selectively enhance tumour delivery are lacking.

Launch pad lightning protection effectiveness [PDF]

open access: yes
Using the striking distance theory that lightning leaders will strike the nearest grounded point on their last jump to earth corresponding to the striking distance, the probability of striking a point on a structure in the presence of other points can be
