Abstract: Examples of apparatus and methods for transmutation of an element are disclosed. An apparatus can include a neutron emitter configured to emit neutrons with a neutron output, a neutron moderator configured to reduce the average energy of the neutron output to produce a moderated neutron output, a target configured to absorb neutrons when exposed to the moderated neutron output, the absorption of the neutrons by the target producing a transmuted element, and an extractor configured to extract the desired element. A method can include producing a neutron output, reducing the average energy of the neutron output with a neutron moderator to produce a moderated neutron output, absorbing neutrons from the moderated neutron output with the target to generate a transmuted element, and eluting a solution through the target to extract a desired element. In some examples, the target includes molybdenum-98, and the desired element includes technetium-99m.

Abstract: Apparatus and methods for an airborne biota monitoring and control system are disclosed. Radar and laser/optical sensors are used to detect insects, with detection zones being over water in some embodiments to reduce backscatter clutter. A pest control laser or small autonomous or radio controlled aircraft under automated or human control may be used to disable a targeted flying insect. One embodiment includes use of a head-mounted display for displaying insect targeting information superimposed on a real landscape view. Technologies such as adaptive lens, holographic optical elements, polarized radar and/or laser beams, light amplifiers and light guides, thin disk, spinning disk, or vertical cavity surface emitting lasers enhance performance of the apparatus or reduce cost of the apparatus. Also disclosed are methods of discrimination of insect types using spectral information and dynamic relative variation of spectral intensities at different wavelengths reflected from an insect in flight.
