This value controls the degree of intensity attenuation by the filter at its point of maximum density.

Audience member In the 1918 flu I understand that they theorized that there was some attenuation of the virus when it made the leap into humans.

The attenuation of downside risks and pleasant surprises in developed and emerging economies could lead to a further increase in demand for risky assets (equities and credit), which would reinforce economic recovery via wealth effects and lower borrowing costs.

And you can see from this map, there's this incredible geographical signature of a series of islands that were out in the harbor and a matrix of salt marshes and beaches that served as natural wave attenuation for the upland settlement.

The task force report also noted that in many countries, a large proportion of the refrigerators produced had already gone into landfills, and that issues related to the attenuation of landfill emissions through stimulation of breakdown of CFC 11 deserved further attention.

Lastly, the task force had noted that in many countries, 60 per cent of the refrigerators produced using CFC 11 blowing agents had already gone into landfills and that issues related to the attenuation of landfill emissions through anaerobic degradation of CFC 11 deserved further attention.

Because microwave radiation suffers very little attenuation in passing through clouds and rainfall (except very heavy thunderstorms), the ERS 1 and ERS 2 SARs provide images of the tropical areas that heretofore could not be thoroughly mapped with LANDSAT and SPOT because of the constant presence of clouds in the region.
