Theoretical investigation of variable infra-red emission by cosmic dust sources
Thesis
Bode, M. F. (1979). Theoretical investigation of variable infra-red emission by cosmic dust sources

Light travel time considerations are applied to the development of the infra-red flux from a cloud of dust grains surrounding a variable cosmic source of heating radiation. The properties of individual grains are explored, and the equation of radiati... Read More about Theoretical investigation of variable infra-red emission by cosmic dust sources.

The effects of hydrogen, oxygen and water vapour on the work function and resistance of titanium films
Thesis
(1980). The effects of hydrogen, oxygen and water vapour on the work function and resistance of titanium films

The changes of work function; ? and resistance; R of titanium films were measured in U.H.V. at room temperature, when- hydrogen, oxygen and water vapour interacted with them. The interaction of hydrogen reduced R by 30% after an initial increase of 1... Read More about The effects of hydrogen, oxygen and water vapour on the work function and resistance of titanium films.
