Stress corrosion crack inhibiting method for titanium
Addition of oxyanions to liquid solvents in excess of the number of chloride, bromide, or iodide ions present prevents cracking of titanium-aluminum alloys under exposure to aqueous and other solvent environments. The molar concentration of oxyanion is set from 10 to 100 times higher than concentration of halide ions

A new device for communication systems
A communication device and modulation capability were developed for the transmission of digital data or voices from point to point. This device is a fast-switching phase coherent frequency synthesizer. When this synthesizer is appropriately incorporated in a communication system it can provide interference resistance, multiple-user capability, user identification, ranging, navigation, Doppler correction, and digitized communication (voice and data). The application of this device to aircraft/airport complex and law enforcement communications is discussed
E2/M1 ratio from the Mainz data
We suggest that the error quoted in the Mainz determination of the E2/M1
ratio (at the resonance energy) should be enlarged. A term dropped in
expressions used by this group could be significant.Comment: 2 pages of text. Submitted to the Comments section of PR
Developing generative themes for community action
This chapter explores a range of participative methods for working with groups to achieve social change in community settings. It draws on the work of Paulo Freire and examines how workers can facilitate processes of dialogue and critical reflection which enable local people to develop solutions to the issues they are dealing with
Magnetic field reversals and galactic dynamos
We argue that global magnetic field reversals similar to those observed in
the Milky Way occur quite frequently in mean-field galactic dynamo models that
have relatively strong, random, seed magnetic fields that are localized in
discrete regions. The number of reversals decreases to zero with reduction of
the seed strength, efficiency of the galactic dynamo and size of the spots of
the seed field. A systematic observational search for magnetic field reversals
in a representative sample of spiral galaxies promises to give valuable
information concerning seed magnetic fields and, in this way, to clarify the
initial stages of galactic magnetic field evolution
