The phrase "attenuation down" is not standard in written English and may cause confusion.
It could be used in contexts related to signal processing or telecommunications, where it might refer to a reduction in signal strength.
Example: "The technician noted that the attenuation down of the signal was affecting the overall performance of the network."
Alternatives: "signal reduction" or "decrease in attenuation."
The results indicated that air velocity attenuation down the direction of the supply air affected dust distribution at the bottom of duct, to some extent, and the number of microorganisms was positively correlated with the quantity of dust.
Not only does the slow diffusion of CO2 in the aquatic environment limit its uptake by leaves (Smith and Walker 1980), but also the decreased light availability, due to attenuation down the water column, impairs photosynthesis (Sand-Jensen 1989; Pedersen and Colmer 2006).
There exists a similar problem at high frequencies, where the attenuation goes down at about the square of the inverse frequency as soon as the frequency limit of ray formation is exceeded at which the free duct is about half a wavelength wide.
This work presents the first climatologic maps of diffuse attenuation of down-welling solar radiation (KdPAR and Kd490 coefficients) for the Azores derived from full resolution (FR) MERIS satellite imagery.
In this paper, we study the loss of coaxial cables and rectangular waveguides using a resonant-cavity technique from which we extract attenuation constants down to (0.005 mbox{dB}/mbox{m}) accurately between room and cryogenic temperatures at the tens of millikelvin level.
Similarly, it is uncommon to extract attenuation information from down-hole tests.
Transgene expression shut-down, attenuation and/or variability from integrated retroviral vectors pose a major obstacle to gene therapy trials involving hematopoietic cells.
An attenuation of receptor down-modulation was observed upon 30 min of stimulation in Syk− or Syk KI cells (Figure 3A), suggesting a role for active Syk in regulating FcεRI surface expression.
We further transiently depleted CCR2+ cells and show that such treatment recapitulates many facets of late IL-12 depletion, including loss of KLRG1+ cells and an attenuation in the down-regulation of CXCR3 expression.
Results show that the shear band can improve the shearing strength and slow down the attenuation of load bearing capacity after reaching the shearing strength, without obviously increasing the thermal conductivity.
We have performed measurements of attenuations constants down to (0.005 mbox{dB}/mbox{m}) using a resonant-cavity technique at cryogenic temperatures.
