She recognised that mancing was held back because power came from diffuse and poorly understood sources.

It was designed to obtain data in the far ultraviolet region of the spectrum from diffuse sources of light.

This instrument collected data on X-ray radiation from diffuse sources in deep space.

Illumination from both direct and diffuse sources were periodically measured.

They could have a diffuse source, from collisions between charged particles and the gas abundant in interstellar space.

The arched walls were cool blue, fading to white overhead where it was lit by a diffuse source.

The transport sector consists of many small diffuse sources that we thought would be difficult to monitor, administer and control.

The common position provides for an exception for pollutants from diffuse sources.

Such an exception would complicate the monitoring of diffuse sources and lead to legal uncertainty.

Further, university lobbyists must cope with the diffuse sources of scientific research money.
